Anaphylaxis
1
Anaphylaxis is a severe adverse event with rapid onset, usually occurring within 5 - 30
minutes, but can occur within hours of administration of medication. It is characterised by
respiratory distress, hypotension and/or circulatory collapse. Symptoms can range from mild
to severe with early signs such as generalised widespread erythema and urticaria.
Signs / Symptoms1
Mild
•
urticaria (large itchy red patches or lesions on the skin)
•
erythema
•
swelling around eyes
•
gastrointestinal disturbance i.e. abdominal cramps, diarrhoea, and/or vomiting
•
no airway obstruction.
These signs may progress to become severe anaphylaxis.
Moderate
•
feeling worried or frightened
•
flushed face.
These signs may progress to become severe anaphylaxis.
Severe
•
coughing or wheezing
•
swelling of the tongue, lips and tissue of the face and neck
•
limpness and pallor (particularly in children)
•
noisy inspiration or expiration – indicating obstruction of the upper airway from
angioedema of the hypopharynx, epiglottis, and larynx)
•
subjective feeling of retrosternal tightness, dyspnoea with audible expiratory wheeze –
indicating lower airway obstruction from bronchospasm
•
profound hypotension, shock, rapid or thready pulse
•
tachycardia and central pulse weak or absent
•
loss of consciousness or fitting.
Management
2
•
stop giving medication
•
call for assistance and stay with the client
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
•
immediately notify a MO
•
call emergency or ambulance (as per internal policy/procedure).
•
maintain Airway, Breathing, and Circulation
•
commence basic life support as indicated
•
if client is conscious, place supine in “head down and feet up” position (unless this
results in breathing difficulties)
•
if client is unconscious, place him/her on the left side in ‘recovery’ position and keep the
airway clear
•
give adrenaline by deep intramuscular injection (see below for dosage or Australian
Immunisation Handbook)
–
adrenaline is indicated for any signs of anaphylaxis with respiratory and/or
cardiovascular symptoms or signs
–
adrenaline is not indicated if erythema (flushing) or itching is the only presenting
symptom
–
if there is no improvement in the client’s condition within five minutes, repeat dose of
adrenaline every five minutes until there is improvement.
•
give 100% oxygen at high flow rate via face mask if available
•
all cases should be transferred to hospital for observation and treatment. Document
details of client management and send this to the hospital with the client
•
clearly document
–
the episode in the client’s record including BP, respiratory rate, localised reaction or
skin eruptions, respiratory involvement, wheezing or coughing
–
the drug responsible for the reaction and mark it in the client’s chart.

CLINICAL MANAGEMENT GUIDELINES
Atrophic vaginitis
It is normal for the post menopausal female genital tract to undergo atrophy. The appearance
may be of a pale epithelium or, where the thin epithelium reveals surface blood vessels,
a deeper red colour. No treatment is required if asymptomatic except for Pap smear
management.
Signs / symptoms
•
vaginal dryness
•
dyspareunia
•
asymptomatic with:
–
atrophic appearance of genital tract
–
unsatisfactory pap smear report due to atrophic cellular changes on cytology.
Management
Conditions requiring NO to refer to or at minimum consult with a MO or NP
(if appropriate/available):
•
persistent, recurrent symptoms
•
no response to treatment
•
contraindication to treatment
•
client requests ongoing treatment
•
immunosuppression e.g. HIV positive client
•
abnormal findings of significance
•
findings outside NOs scope of practice.

Bacterial vaginosis (BV)
Bacterial vaginosis (BV) is a common cause of vaginal discharge in women of childbearing
age2. BV results from a decrease in concentration of normal hydrogen-peroxide producing
lactobacilli flora and an increase in other vaginal organisms, especially anaerobes such as
gardnerella vaginalis2, 3. The absence of inflammation indicates it is vaginosis instead of
vaginitis. BV is considered endogenous in origin3.
Signs / symptoms4-7
Symptomatic with a minimum of three of the following:
•
thin, greyish/white, homogenous discharge that adheres to vaginal walls
•
increased amount of vaginal discharge
•
malodour or “fishy odour” which is more noticeable during menstruation or after sex
•
pH of vaginal discharge is alkaline (>4.5)
•
introital dyspareunia and vulval irritation is usually absent or minimal.
Investigations5 - 8
Testing should be performed when a client presents with vaginal discharge. Always examine
the cervix and vagina.
•
speculum examination
•
take swab from the posterior vaginal wall for M/C/S
•
wet preparation – mix the vaginal secretion with two drops of normal saline on
a microscope slide and examine under 400 x magnification. This allows precise
identification of the three major causes of vaginitis. If BV is suspected, look for clue cells
•
vaginal smear – smear swab from vaginal wall onto a microscope slide, air-dry, heat fix,
gram-stain and examine under 1000 x oil-immersion magnification. This allows precise
identification of clue cells and absence of lactobacilli
•
vaginal culture – place swab from vaginal wall into a suitable transport medium (Amie’s
or Stuart’s medium with added charcoal) and send for culture testing. Positive culture
for gardnerella vaginalis does not necessarily indicate BV as this micro-organism may be
present in low numbers as a commensal in many women.
•
vaginal pH
•
KOH whiff test positive for volatile amines.
In asymptomatic client:
•
8
Treatment is not necessary however it is advisable before invasive procedures (i.e. IUD
insertion, hysteroscopy or termination of pregnancy) as there is association between
bacterial vaginosis and pelvic inflammatory disease.
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
•
Treatment in pregnancy is advisable, as there are reports of association with premature
rupture of membranes and ascending infection, although effectiveness of this measure
has had variable success in studies to date3.
Management
Conditions requiring NO to refer to or at minimum consult with a MO or NP
(if appropriate/available):
•
persistent symptoms
•
abdominal or pelvic symptoms e.g. pain or PID
•
client is pregnant or breastfeeding
•

Client education
•
discuss vulval and vaginal health e.g. no soap or douching
•
reinforce that BV is not a sexually transmissible infection and that compliance is
important
•
treatment is not necessary if asymptomatic, but it is required before invasive procedures
such as IUCD insertion, hysteroscopy or termination of pregnancy
•
recurrence is common and little is understood about why it recurs. It may be related to
sexual activity and menstruation as semen and blood alter the vaginal environment

•
take Metronidazole with food and avoid alcohol for 24 hours post treatment
•
take Tinidazole with food and avoid alcohol for 72 hours post treatment
•
Clindamycin cream contains mineral oil which may weaken latex or rubber such as
condoms or vaginal contraceptive diaphragms, therefore use of the contraceptive
products is not recommended within 72 hours following treatment with Clindamycin
cream 2%. Ingredients can cause burning and irritate eyes. In the event of accidental
contact, rinse eye adequately with cool water

Contact tracing14
There is some evidence of sexual transmission between women who have sex with women,
so female partners of women should be contacted and offered treatment48. Male partners do
not need to be contact traced or treated
Follow-up2
14
•
if BV recurs soon after initial treatment, client may require longer course of
Metronidazole
•
if treatment is given during pregnancy to reduce risk of pre-term birth, women should be
re-tested 4 – 6 weeks after treatment and retreated if necessary
•
If symptoms have not resolved consult with MO.

Balanitis and balanoposthitis
Balanitis is an inflammation of the glans penis. Balanoposthitis is an inflammation of the
foreskin and glans in uncircumcised men. Neither condition is classified an STI and is
generally a result of an overgrowth of organisms (fungal or bacterial) which are normally
present on the skin of the glans / penis. One of the most common causes is candida albicans
and other causes include contact dermatitis and mechanical trauma15, 16.

Candidiasis
Candida, a yeast that is considered normal flora in the gastrointestinal and genitourinary
tracts, has a tendency to overgrow and cause genital symptoms when there is a change
or imbalance in normal vaginal acidity due to the use of oral contraceptives, pregnancy,
antibiotic use, diabetes mellitus or compromised immune systems. Vulvovaginal candidiasis
(VVC) is generally caused by candida albicans and is the most common form of genital
mucosal candidiasis7,18. It is not considered an STI, however male partners of women with
thrush may become secondarily infected and develop candidal balanitis and female partners
may develop candidiasis.
Signs / symptoms3, 5 - 7
•
vaginal discharge (varying from thick, white ‘cottage-cheese like’ to a thin white
homogeneous discharge)
•
adherent plaques of yeast on vaginal wall
•
pruritus
•
genital discomfort, external dysuria, dyspareunia or vaginal soreness
•
vaginitis, vulvitis or vestibulitis
•
vaginal pH remains normal (around 4.5)
•
fissures, vulvar swelling or excoriations.
•
balanitis
•
erythema of glans
Note: Severe candidiasis can often be confused with genital herpes.
Investigations3, 5 - 7
Test clients presenting with abnormal vaginal discharge, vulval erythema or itch. Perform a
speculum examination if the vulva is not too painful. Always examine the cervix and vagina in
cases of vaginal discharge.
Uncomplicated vulvovaginal candidiasis (VVC)
Characterised by sporadic or infrequent episodes with mild to moderate symptoms, immunocompetence, likely to be caused by candida albicans.
Vaginal
18
•
swab from posterior vaginal wall with transport medium (Amie’s or Stuart’s medium with
added charcoal) for M/C/S
•
swab from posterior vaginal wall for wet preparation/gram stain
(if available this allows precise identification of spores and pseudo hyphae characteristic
of candidiasis)
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
•
vaginal pH (usually normal below 4)
•
offer additional STI screening if indicated.
Complicated vulvovaginal candidiasis
Characterised by recurrent candidiasis >4 times per year, severe VVC,
immuno-suppression, debilitation or pregnant client.
Vaginal
•
swab from posterior vaginal wall for M/C/S (to check for candida species).
Serology
•
HIV.
Note:
•
Candida albicans may be detected via vaginal smear or M/C/S, however, a positive
culture may not indicate symptomatic infection as it presents in low numbers as part of
normal flora in many asymptomatic women
•
Consider systemic causes of candidiasis in cases of complicated VVC. i.e. people with
diabetes mellitus or a compromised immune system are more susceptible to increased
skin and mucosal colonisation with candida albicans.19 Additional investigation or referral
to a medical officer may be required depending on history and examination e.g. HIV
serology, random or fasting BSL and HbA1C.
Management
Conditions requiring NO to refer to or at minimum consult with a MO or NP
(if appropriate/available):
•
persistent, recurrent symptoms
•
no response to treatment
•
contraindication to treatment
•
abdominal pain or pelvic symptoms i.e. pain or PID
•
client is pregnant
•
immunosuppression e.g. HIV positive client
•
abnormal findings of significance
•
findings outside NOs scope of practice.
Note:
•
However, if Candida is identified and the client’s symptoms have resolved, discuss with
client refraining from treatment unless symptoms return.
•
If candidiasis recurs frequently, consider underlying causes such as diabetes,
immunosuppression, HIV infection and antibiotic use. Exclude other recurrent vulval
symptoms such as herpes and dermatitis. In most cases, no cause can be found.

Chancroid
Chancroid is an acute ulcerative disease caused by the bacteria Haemophilus Ducreyi.4,8 It
is rare in Australia, but is endemic in places such as South-east Asia, India or Africa. It may
be confused with other genital ulcerative disease but should be suspected following sexual
contact in an endemic area or with a person from an endemic area. It is transmitted by direct
contact with discharge from open lesions during sexual activity. Auto-inoculation to nongenital sites is rare, but can occur.
Signs / symptoms7,22, 49
Incubation period is 3 -10 days following sexual exposure.
•
Lesions commence at the site of inoculation as a tender erythematous papule which
becomes pustular, eroded and ulcerates
•
in males, commonly on the prepuce near the frenulum or in the coronal sulcus. In
females, generally at the vaginal entrance and less commonly painless vaginal and
cervical ulcers49.
•
Perianal and extragenital lesions may occur.
•
ulcers are typically painful and nonindurated with ragged edges. Base may be may be
covered with yellow or grey necrotic purulent exudate, ands ulcer frequently bleeds when
scraped.49
•
associated with painful regional adenitis in about 50% of cases
•
10-40% of people with Chancroid have suppurating inguinal lymphadenopathy or
“buboes”.49
•
constitutional symptoms are usually mild (if present at all)
•
painful unilateral adenitis.
Four criteria for formulating a diagnosis of chancroid
•
presence of one or more painful ulcers
•
presence of regional lymphadenopathy
•
a negative Treponema pallidum evaluation or negative serology at least seven days after
the onset of symptoms
•
negative HSV culture from the ulcer exudate.
Investigations
Lesion:
•
GUMP tests – HSV I and II, T. Pallidum, H. Ducreyi, K. Granulomatis
•
culture in specialised medium for haemophilus ducreyi
SECTION 4
2010
27
–
collect from base of ulcer or aspirate from bubo
–
consult MO and laboratory prior to collection.
•
Offer additional STI screening (including HIV) as indicated by history
•
Testing for Chancroid should not occur in isolation.
A PCR test has been developed which is available from Queensland Health Pathology
Services only in the Northern Zone of Queensland as part of the Genital Ulcer Multiplex PCR
(GUMP) test. It is likely that a PCR test will replace the need for culture in the future.
Diagnosis should only be made by a specialist, based on clinical presentation, history of
exposure, and after exclusion of other causes of genital ulcers.
Management
Conditions requiring NO to refer to or at minimum consult with a MO or NP (if appropriate/
available):
•
Suspected or laboratory confirmed chancroid
•
no improvement after three days of treatment
•
no resolution of lymphadenopathy
•
client is pregnant or breastfeeding
•
immunosuppression e.g. HIV positive client
•
abnormal findings of significance.
Treatment

•
Antibody susceptibility may vary according to geographical region of contact
•
Differentiation of genital ulcerative disease is inaccurate, particularly in areas where
more then one causative organism is endemic or prevalent at high rates.24 This is
compounded by the presence of HIV infection which may alter clinical manifestations
and patterns of GUD occurrence. Recent evidence indicates that HSV 2 is increasing in
many populations as the main cause of GUD.24 After detection of GUD (i.e. chancroid,
donovanosis, LGV or HSV) it is important to consider additional investigation and
treatment based on local sensitivity patterns.

Chlamydia
Chlamydia is caused by serovar D - K of chlamydia trachomatis, while other serovars are
responsible for causing trachoma and lymphogranuloma venereum (LGV). Chlamydia infects
the columnar epithelial cells of the urethra, endocervix, fallopian tubes, rectum, oropharynx,
epididymis and conjunctiva.3, 21 It is the most common notifiable disease in Australia among
young people and the most common cause of urethritis in males and cervicitis in females.
Signs / symptoms
Female
•
abnormal vaginal discharge or bleeding (i.e. post coital or IMB)
•
dysuria
•
lower abdominal pain, pressure or heaviness
•
chlamydia cervicitis is indistinguishable from other causes of cervical infection on clinical
examination. Signs and symptoms often go unrecognised and include intermenstrual
bleeding, post coital bleeding and PV discharge
•
approximately 10 - 15% of chlamydia cases (in females) are complicated by pelvic
infection, resulting in pelvic inflammatory disease (PID). Tubal damage can increase risk
of ectopic pregnancy and infertility. Symptoms may include lower abdominal pain and
dyspareunia.
Male
•
dysuria
•
mucoid, watery or mucopurulent discharge and urethral irritation 1 – 3 weeks after
exposure
•
epididymo-orchitis presents as a painful swollen testicle and is occasionally a
complication of chlamydia.
Both
•
asymptomatic (most common)
•
anorectal pain or discharge
•
Less common indicators include sore throat, eyes, joints or other signs of complicated
infection.
Investigations
Test symptomatic or asymptomatic clients who identify risk behaviour through unprotected
sexual intercourse and/or known contacts of chlamydia, gonorrhoea, epididymo-orchitis or
pelvic inflammatory disease.
If there is history of the client performing unprotected fellatio or being the receptive partner
in unprotected anal sex, take swabs from the rectum and pharyngeal sites for PCR.

Note:
•
first catch urine or self-obtained low vaginal swab for chlamydia PCR is appropriate if
unable to do a speculum examination and asymptomatic
•
if males present with urethral symptoms it is recommended to also take a swab of the
urethral discharge for gonorrhoea M/C/S
•
PCR is not validated for pharyngeal, rectal or low vaginal sites, but is recommended.
Positive results should be checked with a supplementary test in the laboratory.
•
PCR has high specificity and sensitivity when used in high prevalence groups, including
those aged 15 - 25 years, symptomatic clients or clients with risk history. Care should be
taken in interpreting PCR results in low prevalence populations.

Donovanosis
3, 7, 21
Donovanosis is a chronic, progressively destructive genital ulcerative infection caused by the
bacteria klebsiella granulomatis. It generally occurs in tropical climates such as Papua New
Guinea. Infection in Australia is rare, but is more predominant in the Indigenous populations
of northern and central Australia.
Signs / symptoms
Most commonly affected areas include the penile shaft and glans, vulva and perianal skin.
•
starts as a papule or subcutaneous nodule which ulcerates
•
four classical types:
•
–
ulcerogranulomatous – is the most common and may appear as beefy red
granulations or painless ulcers with thick, rolled edges
–
hypertrophic verrucous - like a dry walnut
–
necrotic destructive - deep and foul smelling
–
sclerotic or cicatricial - fibrous scar tissue.
if regional lymph nodes are involved, it can lead to progressive tissue invasion from the
genitals to the groin.
Investigations3
Test all clients who present with ulcerated lesions (especially those living in rural and remote
areas). When investigating suspected cases, always test for common causes of genital
ulceration i.e. herpes and syphilis.
Lesions
•
perform genital ulcer multiplex PCR (GUMP) swab. Use a sterile cotton-tipped swab to
swab the centre and edges of the lesion aiming to moisten the swab with ulcer exudate,
then place into a dry sterile container. This test is used to detect herpes simplex virus,
treponema pallidum, klebsiella granulomatis and haemophilus ducreyi
•
press slide for Donovan bodies. Clean the lesion with saline, then press a glass slide on
the lesion, ensuring that the base and the edges of the lesion are pressed onto the slide.
Allow to air-dry.
•
HSV PCR swab of lesion
•
punch biopsy of lesion and non-infected tissue (advancing edge) for Donovan bodies
should be collected if there is no improvement in lesions after six weeks of treatment
•
serology
•
–
syphilis
–
HIV.
Discuss additional STI screening with the client.
SECTION 4
2010
43
Note:
•
testing for donovanosis should not occur in isolation
•
donovanosis is often diagnosed from clinical evidence and on epidemiological grounds.
Laboratory confirmation of diagnosis is not required for notification or treatment
•
the GUMP test is funded for Indigenous clients who have genital lesions, where
donovanosis is suspected or the cause is unclear. If a non-Indigenous person is
suspected of having donovanosis, reach agreement with the laboratory to process the
GUMP specimen.

To minimise discomfort:
•
reconstitute each 900mg in minimum 4mls of water for injection
•
use a 5ml syringe
•
hold vial vertically and shake until the powder is absorbed
•
prepare immediately prior to administration
•
warm the injection by rolling between palms of hands prior to administration. This can
help reduce discomfort for the client.
Do not heat >50oC
•
if there is a delay in administration following preparation, rotate syringe vertically prior to
administration to ensure powder is mixed. This will reduce obstruction of the needle due
to precipitation of the suspension
•
attach a 21 gauge or 19 gauge needle to the syringe just prior to injecting suspension to
prevent blockage of needle
•
administer in the upper-outer quadrant of the gluteus maximus
•
give two injections - one in each buttock
•
apply pressure to the injection site for at least 10 seconds prior to administration.
Note:
•

is compounded by the presence of HIV infection which may alter clinical manifestations
and patterns of GUD occurrence. Recent evidence indicates that HSV 2 is increasing in
many populations as the main cause of GUD25. After detection of GUD (i.e. chancroid,
donovanosis, LGV or HSV) it is important to consider additional investigation and
treatment based on local aetiology and sensitivity patterns.
•
COC users taking a short course (<3 weeks) of antibiotics should be advised to use
additional contraception (i.e. condoms) during treatment and for seven days after
antibiotics have been stopped.13
Client education
•
keep lesions clean and dry
•
if there is purulent discharge, sitz baths or saline cleansing can relieve discomfort
•
protect skin from sunlight (especially between 10am – 3pm) as some macrolide
antibiotics increase sensitivity to sunlight. If there is a rash, itching, redness or severe
sunburn consult a MO
•
encourage client to refrain from sexual contact until lesions are completely healed and
partner(s) are treated
•
Offer condoms and lube
•
Offer screening for other STIs
•
client fact-sheet available at www.health.qld.gov.au/sexhealth
•
provide MIMS Medication Consumer Information www.ckn.health.qld.gov.au
Contact tracing14
Offer all partners who had sexual contact during the period of active lesions and 40 days
prior to the onset of symptoms, an STI screening and treat presumptively for donovanosis.
Follow-up
•
this condition is highly stigmatised so ongoing support and counselling is important
•
review weekly until healed and symptoms resolved
•
if there is no improvement within six weeks refer to a MO
•
review in three and six months to ensure there is no evidence of reinfection

Dyspareunia
Recurrent or persistent genital pain experienced before, during, or after sexual intercourse,
penetration or masturbation is classified as dyspareunia. It is situational or generalised
in presentation and can be acute or chronic (acquired or lifelong). 1-5 The Diagnostic and
Statistical Manual of Mental Disorders fourth edition (DSM IV) classifies dyspareunia as a
sexual pain disorder under sexual dysfunction and lists the additional criteria for diagnosis as
a recurrent or persistent genital pain associated with sexual intercourse; and a disturbance
that causes marked distress or interpersonal difficulties.1,2
Dyspareunia can be related to physical, neurological and complex psychosocial issues.2,3
Predisposing risk factors can include anxiety, depression, history of sexual assault or
specifically in females – peri/post menopause and pelvic inflammatory disease.4,5 Identifying
when the pain occurs in relation to the stage of a sexual act is helpful in determining the
cause.6 Dyspareunia is rare in males.
History
A detailed history should include assessment of possible physical, neurological and
psychological causes as ongoing management, treatment and indication for referral to
medical officer is dependant on the suspected cause. Examination and investigations will be
guided by the comprehensive history findings.
Females
A detailed history should include:
•
sexual, medical, surgical and family history including medication history
•
specific questions related to pain:
–
nature (i.e. when and where the pain occurs)
–
onset (i.e. before, on initial penetration, during or after sexual intercourse, with
orgasm or positional)
–
location (i.e. superficial, at vaginal entrance, vaginal or deeper, single or multiple
sites)
–
duration and severity (i.e. is pain lifelong or acquired, how long does it last?)
–
frequency (i.e. permanent or intermittent - does the pain occur with every sexual
encounter? If not, what is different about the times when no pain is experienced?)
–
characteristics (i.e. stinging, cutting, burning, pulling or stabbing)7
–
radiation (i.e. does pain travel to the perineum, rectum, abdomen etc)
–
contributing or aggravating factors:
>Is it situational or general?
>Does it occur with all partners, foreplay and non-penetrative sexual behaviour or
with penetration with fingers, sex toys, tampon
50
QUEENSLAND SEXUAL HEALTH

> What makes it better – if anything, is it bad enough to take pain medication, does
using lubrication stop the pain?
>Are there any aggravating factors: sex, direct pressure, urination, menses, bowel
movement, diet, orgasms.8

Examination
Females
•
Examination should be guided by comprehensive history findings
•
General examination - include skin, nails, abdomen and extremities
•
Palpate abdomen for tenderness and guarding
•
Examine the vulva and perianal region for erythema, lesions, ulcers, rashes,
abnormalities, anatomical presentation, scarring or tenderness
•
Examine vaginal opening and hymenal membrane for erythema and thickening, presence
or absence of lesions, anatomical abnormalities, vaginal discharge or vulvar soreness
•
Palpate vulva and perineum for pain, tenderness, masses or scarring
–
assess for vestibulodynia by gently parting the labia minora and using a moist
cotton-tipped swab to determine whether there is pain with pressure at one or more
points around the vestibule.
•
Vaginal examination - gently slide a single finger into the vagina and depress the levator
ani muscles at multiple angles looking for hypertonicity, spasm or tenderness.
•
Speculum examination (If tolerated)
•
–
observe for anomalies, discharge, fissures, erosions, ulcers and atrophy
–
examine the vagina for inflammation, discharge, lesions or other abnormalities
–
assess the cervix for inflammation, oedema, discharge, bleeding and other
abnormalities.
Bimanual examination (if tolerated and pregnancy test negative)
–
assess cervix for cervical excitation
–
assess uterus for size, position and tenderness
–
assess adnexae for tenderness and masses.
Males
54
•
General examination – include skin, nails, abdomen and extremities
•
Genital examination – standing and lying down. Look for scarring (from circumcision or
from old piercing), feel for plaques along the shaft, swelling of the glans, prepuce or
shaft, and lesions on the skin
•
Testes – look for symmetry, size, shape, tenderness, heat, skin lesions, and lesions within
the scrotum, testes or epididymis
•
Feel for the vas deferens from the length up to the groin.
•
Examine the groin for inguinal hernias
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
•
Standing – check for symmetry (one testes is usually slightly lower than the other),
varicosities (varicocele), hernias or abnormal penile curvature (may be difficult to see
with a flaccid penis).
Note: The goal of physical examination is to localise the pain or discomfort, determine the
type and location of any pathology.4,5 In most cases, female dyspareunia requires referral or
at minimum, consultation with a MO for ongoing examination and management. Therefore
the extent of examination performed by a NO is dependant on their experience, setting and
the clinical scenario.

Management / treatment
Females
Female sexual dysfunction often involves several aetiologies contributing to the problem.10
Management must be tailored to the sexual issue and take into account underlying physical
and psychological factors (including relationship). Conditions that may alter sexual function
(e.g. depression, sexual issues related to medication or substance abuse) should also be
considered.
Medical referral
Conditions requiring NO to refer to or at minimum consult with a MO or NP (if appropriate/
available):
•
suspected organic basis to dyspareunia
•
uncertain diagnosis
•
persistent symptoms after treatment
•
ongoing medical management
•
contraindication to treatment
•
client is pregnant or breastfeeding
•
abnormal findings of significance (i.e. in males – varicocele, hernia, penile curvature,
intrascrotal, testicular torsion, testicular or vas deferens lesions)
•
immunosuppression i.e. HIV positive client
•
findings outside NOs usual scope of practice.
For all other cases
•
Refer to management and treatment of specific condition diagnosed.
Note: requirements for referral and medical consultation will depend on history and clinical
findings. For example, if an infection related to STI is obvious, offer treatment according to
findings and refer to a MO as indicated. If any mental health issues are identified refer the
client to a psychologist/counsellor. Consider epididymo-orchitis or testicular torsion with
tender / painful testes in younger males.

•
review client in three days to ensure resolution of symptoms and response to treatment.
If no improvement, consider changing treatment regimen, surgical referral3 or alternate
diagnosis (i.e. testicular infarction, abscess formation, mumps, testicular tumour or
tuberculous epididymo-orchitis)
•
recommend retesting for gonorrhoea and chlamydia in three months if confirmed STI
related infection, as reinfection is common.
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
Genital herpes (HSV)
Genital herpes is the most common cause of genital ulcer disease. It is caused by herpes
simplex virus 1 and 2 (HSV 1 and HSV 2).3 It is a chronic, life-long viral infection7 acquired
by skin-to-skin contact during oral or genital sex. It can be acquired from symptomatic
or asymptomatic partners. About 70% of genital herpes is caused by HSV 2 and is
primarily transmitted by a person unaware of their infective status or during an episode of
asymptomatic shedding.7
Perinatal transmission is a rare but serious infection with high morbidity and mortality.
Transmission is more likely to occur with vaginal delivery at the time of primary maternal
infection. Risk is significantly lower with recurrent HSV lesions or asymptomatic infection at
the time of delivery. A female with a history of genital herpes or an infected partner, should
notify the medical obstetric team immediately. A vaginal delivery is usual for women with a
history of genital herpes, though lesions at the time of delivery would prompt most obstetric
teams to perform a caesarean section.
Signs / symptoms3
Most HSV infections are asymptomatic. Clinical manifestations depend on the site of viral
entry and immunity from previous oral or genital HSV exposure. Manifestations of newly
acquired infection may be severe in non-immune clients, while initial infections are less
severe in clients with prior exposure. Sexually acquired manifestations include genital
ulceration, gingivostomatitis, urethritis, cervicitis and proctitis.
It can be difficult to determine whether a client who presents with herpes for the first time
has a true ‘first’ infection or whether it is a recurrence of previously unrecognised infection.
Multiple, widespread, bilateral lesions, which are at different stages of development and
resolution and at sites of direct mucosal infection are usual indicators of first infection.
In contrast, recurrent lesions are grouped and localised, unilateral, at identical stages of
development and at cutaneous sites along sacral dermatomes.
Primary or initial episode
•
multiple, widespread, painful lesions with associated systemic symptoms
•
atypical presentation may include skin splits, skin irritation, fissures or single lesions.
Recurrent episode
•
localised unilateral painful lesion(s)
•
history of recurrent thrush or lesion(s)
•
atypical presentation can include skin splits, skin irritation or fissures.
HSV infections also present asymptomatically as mild or unrecognised infections. The
severity of presentation depends on existing immunity from previous oral/genital HSV
exposure and the site of infection. Initial infection is less severe in clients with previous
exposure to HSV 1.
SECTION 4
2010
71
Investigations
Test all clients presenting with genital lesions, ulcers, chronic genital skin tears or recurrent
candidiasis.
Lesions
•
HSV PCR swab from the lesion(s)
Serology
•
HSV Serology is not recommended for diagnosis,3 as available tests do not necessarily
distinguish between HSV 1 and HSV 2 antibodies. Type-specific herpes antibody tests are
available but their place in the diagnosis of genital herpes is unclear
•
HIV
•
Syphilis.
Note: Testing for HSV should not occur in isolation. Consider testing for other genital ulcer
diseases and discuss additional STI screening with the client.
Management
Conditions requiring NO to refer to or at minimum consult with a MO or NP (if appropriate/
available):
•
prescription required for recurrent episodic or suppression therapy, analgesia
•
symptoms persist while taking antiviral treatment
•
disseminated infection i.e. meningitis or neurological problems

CLINICAL MANAGEMENT GUIDELINES
Note: For clients living with HIV, suppressive therapy can be changed to Valaciclovir 500mg
orally twice a day12. Consult a HIV specialist for further advice regarding managing HSV in HIV
positive clients.
Suppressive therapy should be discontinued after six months to assess the need for further
courses. Relapse may occur at the end of prophylaxis. There is no evidence that lysine,
zinc, vitamins or other non-mainstream remedies are any more effective than placebo in the
prevention of recurrences.
Pain management
Analgesics, ural sachets, salt baths and local application of ice packs may help reduce
discomfort. Topical antiseptics such as povidone-iodine may also be of benefit.
Topical Xylocaine jelly 2% is a useful adjunct to Valaciclovir or Aciclovir in managing severe
first episodes. It should be applied frequently but for no longer than 24 - 36 hours as there is
a rare risk of sensitisation.

Genital warts – human papilloma virus
(HPV)
There are more than 100 genotypes of the human papilloma virus (HPV). More than 30
of these are known to infect the external and internal anogenital area and may present
as genital warts7. The most common genotypes causing genital warts are type 6 and 11.
High-risk HPV types 16, 18, 31, 33 and 35 are associated with cervical changes, neoplasias7
and other oncogenic anogenital infections3. The majority of anogenital HPV infections
are asymptomatic, unrecognised or subclinical in presentation7. Most HPV infections are
believed to spontaneously regress but infections can persist32. A persistent infection with
high risk HPV types is the most predictive factor in progression to squamous intraepithelial
neoplasia7,32. HPV vaccination is designed to help prevent infection with specific HPV
genotypes and protect against persistent infection.
Genital warts are transmitted by skin-to-skin sexual contact and transmission of HPV can
occur regardless of clinical manifestations3. Incubation period is variable and may be
prolonged. The existence of infectivity and infection in the absence of symptoms makes
interruption of transmission extremely difficult. Transmission rarely occurs perinatally.
Signs / symptoms
•
asymptomatic carriage of the virus, detectable as viral DNA in affected cells
•
cytological changes not apparent to the naked eye but detectable by histological
techniques
•
cervical, vaginal, vulval, anorectal and penile lesions seen by colposcopy but not
apparent macroscopically
•
recognisable genital warts or condylomata acuminata.
Investigations
Clients presenting for a sexual health check should be examined for genital warts. Partners
of people diagnosed with genital warts should also be encouraged to attend a sexual health
check.

CLINICAL MANAGEMENT GUIDELINES
Management
Conditions requiring NO to refer to or at minimum consult with an MO or NP (if appropriate/
available):
•
warts are extensive and potential labour problems are identified
•
no response to therapy after four ablative treatments
•
internal warts
•
abnormal findings of clinical significance or uncertain diagnosis
•
atypical warts including pigmented, indurated, fixed or ulcerated
•
client is pregnant or breastfeeding
•
immunosuppression e.g. HIV positive or transplant client
•
findings outside NOs scope of practice.
Treatment
Indicators
Diagnosis of anogenital warts is based on direct visual examination of lesion. If in doubt,
excise and examine histologically. This should be considered if lesions are atypical, there is
ulceration or attachment to underlying structures or there are prompt or frequent recurrences
after treatment.
Non-wart HPV infection is often diagnosed by the presence of cytological changes on a pap
smear.
Assessed risk factors for HPV may indicate need for vaccination.
Clinic treatment regimen
Factors that may influence selection of treatment include size and number of warts, anatomic
site of wart, wart morphology, client preference, cost and convenience of treatment, adverse
effects and provider experience.
•
Non DTP-SRH endorsed NOs are authorised to administer this regimen only if clinical

Gonorrhoea
Gonorrhoea is caused by Neisseria Gonorrhoeae, a gram negative diplococcus, which infects
the columnar and transitional epithelial cells of the genitourinary tract, rectum, pharynx
and conjunctiva.3 Transmitted predominately by sexual contact it can be transmitted by
autoinoculation or prenatally.
Signs / symptoms
Females
•
dysuria
•
abnormal vaginal discharge or bleeding (i.e. post coital or IMB)
•
lower abdominal pain, pressure or heaviness
•
anorectal pain or discharge.
Gonococcal cervicitis is indistinguishable from other causes of cervical infection on clinical
examination.3 Most cases are asymptomatic. Coexistent pharyngeal and anorectal infections
are common and often asymptomatic. Females can experience rectal infection resulting
from anal sex or the posterior spread of infective secretions from the vagina. Approximately
10 -15% of cases of acute gonococcal cervicitis are complicated by pelvic infection. The
prevalence of penicillinase producing Neisseria Gonorrhoeae (PPNG) varies within Australia
and averages about 5 - 20% of cases. Co-infection with chlamydia is common in cases of
gonorrhoea.
Males
•
dysuria
•
tender, painful or swollen testicles
•
anorectal pain or discharge.
Gonococcal urethritis is often indistinguishable from other causes of urethral infection
on clinical examination.3 It usually presents as purulent discharge within a few days of
exposure and cases are rarely asymptomatic. Coexistent pharyngeal and anorectal infections
are common in men who have sex with men (MSM) and are often asymptomatic. Rectal
infection in MSM results from anal intercourse. Some cases of gonorrhoea are complicated
by epididymo-orchitis. Co-infection with chlamydia is common in heterosexual men and
increasingly common in MSM.

containing charcoal
•
perform a first catch urine test by PCR for nucleic acid amplification to identify
gonorrhoea or chlamydia in asymptomatic clients or during screening programs
•
pharyngeal and anorectal swabs for culture (not smears) should be taken if symptoms
or sexual history suggest infection at these sites. Gram-stained smears should be taken
via proctoscopy if there are symptoms after unprotected anal intercourse. Nucleic acid
amplification testing is not validated at these sites. PCR is still the recommended test
for chlamydia but positive results should be checked with a supplementary test in the

CLINICAL MANAGEMENT GUIDELINES
HIV and AIDS
39
The human immunodeficiency virus (HIV) is a retrovirus which was discovered by French
and American researchers in 1983, and an antibody test for HIV-1 was available the following
year. A less common and less virulent virus is HIV-2, found mainly in West Africa, while only
isolated cases have been detected in Australia39.
The virus causes depletion of CD4 lymphocytes (T4 or T helper cells) and immuno-deficiency
by leaving the immune system open to opportunistic infection and tumours such as
pneumicystis jiroveci, pneumonia, oesophageal candidiasis, cerebral toxoplasmosis,
diarrhoeal diseases, kaposi’s sarcoma and lymphomas. These and many other conditions are
known as AIDS (Acquired Immune Deficiency Syndrome)39.
Australia’s situation
In Australia, HIV is predominantly sexually transmitted and occurs most commonly in
homosexually active men39. However, consider the possibility of HIV infection in any person at
risk of STIs and in those with a history of injecting drug use. In Australia, most incident cases
(>85%) occur in homosexual men, as the virus hasn’t broadly infiltrated injecting drug users
or the heterosexual community. Estimates indicate 17,444 Australians were living with HIV by
the end of 2008. Over the past few years, incident cases of HIV have risen and this is causing
concern. In 2006, 998 HIV infections were diagnosed, an increase of 31% since 2000.
The Asia-Pacific region - particularly Papua New Guinea, Cambodia, Thailand and Myanmar
- are experiencing high growth rates of HIV. Papua New Guinea, Cambodia, Myanmar and
Thailand are experiencing high rates of HIV and there is a significant risk of transmission from
Papua New Guinea to Torres Strait Islander and Cape York communities.
The HIV virus is present in blood, semen, vaginal fluids and breast milk, and can be
transmitted by:
•
sexual intercourse (vaginal or anal)
•
injection of blood, or through mucous membranes contaminated with blood or bodily
fluids
•
infection from mother to infant (in utero, perinatally or through breastfeeding).
Signs / symptoms
HIV disease comprises three phases: acute primary illness, asymptomatic chronic illness and
symptomatic chronic illness. Progression from one stage to another is variable. For further
detail see HIV Management in Australasia: a guide for clinical care58.
History taking
Take a comprehensive history to assess risk behaviours for HIV and conduct a physical
examination to look for clinical manifestations of immune dysfunction or neuropsychiatric
conditions39, 58. Maintain a high index of suspicion because of the varied clinical picture in
HIV58.
SECTION 4
2010
105
Pre and post test discussion60
Provide pre-test and post-test discussion to a client undergoing HIV antibody testing. Pretest discussion is essential to prepare the client for testing and ensure they understand the
benefits, risks and implications of a positive or negative test result. It also enables you to
clarify essential information regarding transmission of HIV, safe sex and injecting drug use.
This is also the ideal time to discuss the availability of PEP to people in high risk groups.
The National HIV Testing Policy, 200660 provides the principles and framework that guide
approaches to HIV testing in Queensland. The policy is available from the Department of
Health and Ageing website – www.health.gov.au.
People may be tested for the following reasons:
•
sexual health check-up (i.e. occupational screen for sex workers)
•
signs or symptoms of HIV
•
named as a contact of STI or HIV
•
antenatal screening (HIV testing should be offered to all pregnant women)
•
immigration screen
•
insurance medical testing
•
blood bank and tissue donation
•
occupational or non-occupational exposure to HIV
•
prior to some employment
Serology testing
Combined antigen and antibody tests are now more widely available and are performed
when an HIV test is requested. These new tests can generally rule out HIV infection after only
weeks from the date of infection. Formerly, it used to take up to three months for an antibody
to become reactive after infection but the new ‘window period’ from acquiring HIV to test
results becoming positive is now less than six weeks
Diagnosis
If a result is positive, do a repeat HIV antibody test to confirm the original result was correct39.
A positive result is confirmed by the Western Blot analysis. Also perform baseline testing for
a range of other infections (including STIs), CD4 count, HIV quantitative RNA test (viral load),
along with a baseline genotypic resistance assay (now considered routine). The genotypic
resistance assay looks for evidence of resistance virus that may have been transmitted to
the individual39. It is estimated that 10 -15% of transmissions in Australia involve a resistant
virus39.
Primary HIV infection
Have a high index of suspicion for acute primary HIV infection (PHI) in clients presenting with
infectious mononucleosis-like febrile illness and be aware that in the first week of primary
106
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
infection, HIV antibody assays may remain non-reactive. HIV PCR (viral load) tests will be
positive - usually at high copy count during PHI but low counts (<10,000 copies per ml) may
represent false positive results. Diagnosis depends on careful assessment of risk factors,
clinical picture, serial HIV antibody assays and the viral load test. Laboratory indicators
may be lowered or raised white cell count, atypical lymphocytes in the blood film and liver
transaminitis39.
Refer clients suspected of having primary HIV infection (but who have non-reactive HIV
antibody assays initially) for specialist review and ensure they are followed up with repeat
HIV antibody tests.
Early in the course of PHI, the HIV antibody screening test may be negative but the combined
antigen and antibody test has a much shorter window period. Special tests such as detection
of the p24 antigen and proviral DNA should be discussed with the laboratory and/or an
experienced HIV clinician. If clinical suspicion remains, repeat HIV Ag/Ab testing39.
Client education for people newly diagnosed with HIV
•
provide contact details for groups such as Queensland Association of Healthy
Communities QAHC (previously the AIDS Council) and Queensland Positive People (QPP).
These groups provide information, support, activities and
self-empowerment
•
offer psychological counselling and support to newly diagnosed clients.
•
Instruct regarding correct use of condoms
•
client fact sheet available at www.health.qld.gov.au/sexhealth
•
provide client with booklets/fact-sheets outlining:
–
natural history and prognosis of HIV
–
explanation on prevention of transmission and superinfection
–
health management including complimentary therapies.
•
recommend vaccination for HAV and HBV
•
discuss pneumococcal and influenza vaccination
•
encourage partner(s) testing
•
discuss need for monitoring
•
discuss legal obligations, disclosure of positive status and discrimination issues. Assure
client that confidentiality will be maintained
•
obtain consent for release of information relating to previous medical care.

•
discuss informing sexual partner(s) and others at risk of exposure (eg. people who inject
drugs), and agree and document method of identifying and notifying contacts(s)
SECTION 4
2010
107
•
contact(s) will often require counselling
•
if primary illness confirmed, trace contacts for at least 6 weeks prior to onset
•
if late HIV infection or infection of unknown origin, contact trace depending on risk and
age of index case (may be necessary to trace back to 1980)
•
offer PEP and STI screening to partner(s) exposed within the last 72 hours
•
screen all contacts and offer additional STI screening
•

Monitoring
People with HIV should attend regular follow-up at 3 - 6 month intervals58 or more
frequently if their clinical or immunological condition warrants it. At each visit, assess the
person psychologically and reinforce the importance of transmission prevention. Physical
examination should look for evidence of immune dysfunction. Arrange haematological,
biochemical, viral load and immune function testing.
At subsequent visits, repeat testing for full blood count, HIV viral load and CD4/CD8
lymphocyte counts, U & E and liver function tests. Falling CD4 counts and rising viral load (+/the development of signs or symptoms of immunodeficiency) indicate a need for antiretroviral
therapy.

recommend annual pap smears after two successive normal smears six months apart. Any
abnormalities should be followed up by colposcopy.
Clients living with HIV do not necessarily cease to be sexually active and recent guidelines
110
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
recommend regular screening for common STIs such as gonorrhoea, chlamydia, ano-genital
herpes and syphilis. Clinicians should discuss responsibilities for preventing transmission
of HIV as well as safer sex practices periodically with clients as part of their routine
management.
Monitoring response to therapy involves resolution of signs and symptoms attributable to
HIV prior to initiation of antiretroviral therapy, including monitoring changes in weight.
Monitor drug toxicity depending on the antiretroviral agents the client is taking. Refer to HIV
Management in Australasia: a guide for clinical care at www.ashm.org.au
Clients with progressive disease (suggested by HIV-related symptoms or deteriorating
laboratory surrogate markers) or those who have just commenced or altered antiretroviral
therapy require more frequent monitoring. Frequency of monitoring in these circumstances
should be made in conjunction with an HIV specialist.
Monitoring for clients on antiretroviral treatment
Monitoring includes clinical assessment and laboratory testing which aims to document
efficacy of therapy ( initial fall in plasma HIV RNA and subsequent rise in CD4) and detection
of toxicity (clinical and laboratory)58.
Assessment should include58
•
History – new symptoms, side effects, adherence, psychosocial issues
•
Examination – weight, BP, body shape changes, peripheral neuropathy, rash
•
Laboratory – plasma HIV RNA, CD4 count, FBE, liver function tests, electrolytes. Fasting
lipids and glucose 6 monthly.
•
Assessment for co-morbidity – depression, recreational drugs use, STIs
•
Assessment of toxicity – peripheral neuropathy, cardiovascular risk factors, lipodystrophy

Prevention
Current39
112
•
Condoms and community health education focussed on at-risk individuals and
communities have shown to be effective in prevention of HIV.
•
Some of the most cost-effective public health initiatives include needle and syringe
programs, and methadone and buprenorphine substitution programs.
•
Post-exposure prophylaxis (PEP) is a combination of two to three antiretroviral agents
given within 72 hours of significant exposure to HIV (usually sexual or occupational). The
medications are taken for one month and reduce the risk of acquiring HIV.
•
Prevent mother to child transmission by using antiretrovirals for the mother during
pregnancy and for the baby for a short period after birth. Breastfeeding is not
recommended in Australia. The overall risk of vertical transmission is 25-20%58.
•
Early diagnosis of primary HIV infection, counselling of the index client and contact
tracing partners is very important. It is estimated that about half of all HIV infections are
caused by someone who was recently infected. Counselling the index client in this setting
can have benefits in reducing onward transmission.
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
Future
•
Vaginal and anal microbicidal agents that can be introduced by the person having sex
(without requiring their sexual partner’s permission) are undergoing trials.
•
Pre-exposure prophylaxis (PREP) – HIV medication taken prior to intercourse may reduce
the risk of HIV infection in those at high risk.
•
Increased emphasis on testing and treatment of chlamydia, gonorrhoea, syphilis and
genital herpes – all of which increase the risk of HIV acquisition and transmission. Trials
looking at suppressing HSV-2 in order to prevent HIV transmission are underway, but
early results appear to be disappointing.
Treatment
Clients should be treated according to Australian antiretroviral guidelines58 available at www.
ashm.org.au.
Treatment is usually commenced when the CD4 count drops to 350cells/µl (usual level for
a healthy adult is 450-1200 cells/µL). Combination antiviral therapy (cART) is indicated
in pregnant women, people with HIV-associated nephropathy or HBV co infection when
hepatitis B treatment is indicated58. Antiretroviral treatment during pregnancy is routine and
can reduce the mother-to-child transmission rate to <1%. Without antiretroviral treatment or
caesarean section the rate is approximately 25%58.
Currently available antiretroviral agents are classified as nucleoside reverse transcriptase
inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), entry and fusion
inhibitors (FIs), integrase inhibitor and protease inhibitors (PIs).
Nucleoside Reverse Transcriptase Inhibitors (NRTIs):
•
Abacavir (category B3 in pregnancy)
•
Didanosine (ddI) (category B2 in pregnancy)
•
Emtricitabine (FTC) (category B1 in pregnancy)
•
Lamivudine (3TC) (category B3 in pregnancy)
•
Zidovudine (AZT) (category B3 in pregnancy)
Nucleotide Reverse Transcriptase Inhibitors:
•
Tenofovir (Category B3 in pregnancy)
Non Nucleoside Reverse Transcriptase Inhibitors (NNRTIs):
•
Efavirenz (Category D in pregnancy)
•
Nevirapine (Category B3 in pregnancy)
•
Etravirine (Category B1 in pregnancy)
Entry Inhibitor
•
Maraviroc (Category B1 in pregnancy)
SECTION 4
2010

Fusion Inhibitors (FIs):
•
Enfuvirtide (Category B2 in pregnancy)
Integrase Inhibitor
•
Raltegravir (Category B3 in pregnancy)
Protease Inhibitors (PIs):
•
Amprenavir (Category B3 in pregnancy)
•
Atazanavir (Category B2 in pregnancy)
•
Fosamprenavir (Category B3 in pregnancy)
•
Indinavir (Category B3 in pregnancy)
•
Lopinavir (Category B3 in pregnancy)
•
Ritonavir (Category B3 in pregnancy)
•

Co-formulated preparations
•
Atripla ( Tenofovir / Emtricitabine / Efavirenz)
•
Combivir (Zidovudine / Lamiviudine)
•
Kivexa ( Abacavir / Lamivudine)
•
Truvada ( Tenofovir / Emtricitabine)
The gold standard of HIV treatment is triple combination antiretroviral treatment (cART)58.
In general, clients receive two nucleoside analogues in combination with either a nonnucleoside reverse transcriptase inhibitor or a (ritonavir-boosted) protease inhibitor.
Only clinicians who have completed an HIV prescriber’s course, attend regular professional
updates and are experienced in the use of antiretrovirals can prescribe these S100s.
Combination antiretroviral therapy (cART) may cause significant side-effects which can limit
the client’s ability to take the medication effectively. Some side-effects include:
•
nausea and diarrhoea
•
skin rashs
•
lipoatrophy (loss of fat from limbs and face)
•
hyperlipidaemia
•
raised liver transaminases and bilirubin
•
impaired glucose tolerance and diabetes.
Ninety-five percent compliance with cART is essential in order to reduce the risk of resistant
virus developing. People with HIV are more likely to also have other issues which can impact
their health including depression, mental illness, higher rates of tobacco and alcohol misuse,
unemployment and poverty.

QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
Prophylactic therapy against opportunistic infections (OIs)
Prophylactic therapy against opportunistic infections in immunocompromised clients is
critical in managing the infection58. Consult an HIV specialist for discussion of opportunistic
disease prevention. Refer to HIV Management in Australasia: a guide for clinical care (2009)
at www.ashm.org.au/publications
Administer primary prophylaxis to clients at risk of developing certain opportunistic
infections such as Pneumocystis Jiroveci Pneumonia PCP (CD4 < 200/µL, CD4 % <14%, or
presence of Oral Candidiasis) or Mycobacterium avium complex disease (CD4 <50/µL)58.
However, primary prophylaxis is not recommended for the following opportunistic infections oropharyngeal/oesophageal candidiasis, CMV disease or cryptococcal meningitis.
Clients with CD4 counts < 50/µL or non-retinal CMV disease are at risk of CMV retinitis and
should have regular HIV specialist ophthalmological review to enable early detection and
treatment of CMV retinitis. Educate clients to notice increased ‘floaters’ or changes to visual
acuity and advise them to seek medical attention if these occur.
Clients who have already experienced opportunistic infection are at risk of recurrent infection
until anti-retroviral therapy induced immune reconstitution occurs. These clients should
receive secondary prophylaxis and consult with an HIV specialist.
Opportunistic infection prophylaxis may cease following antiretroviral therapy induced
immune reconstitution. Consult with an HIV specialist regarding cessation of opportunistic
infection prophylaxis. All clients who are diagnosed with latent tuberculosis should also be
referred to an HIV specialist.
Referral of clients with HIV infection
Clients with HIV should be managed by clinicians experienced in the management of HIV
disease. Optimal models of care involve HIV specialist and general practitioner input.
General practitioners with HIV infected clients would benefit from HIV courses offered by the
University of Queensland at www.som.uq.edu.au/hivandhcvprojects
Post-exposure prophylaxis (PEP) for HIV
If exposed to significant risk of HIV infection through:
•
occupational exposure e.g. deep needle-stick injury
•
non-occupational exposure e.g. unprotected receptive or insertive anal or vaginal
intercourse
•
injecting drug user e.g. needle sharing with a person known or suspected to have HIV
infection
Offer administration of combination antiretroviral therapy for one month. This may provide
benefit if drugs are commenced within 72 hours of exposure. There is little direct evidence of
the effectiveness of PEP, however a substantial body of indirect epidemiological and animal
model evidence now exists for the effectiveness of PEP.
The Queensland Health Guidelines for Management of Occupational and non-Occupational
Exposures to Blood and Body Fluids, 2009 provide detailed advice regarding PEP.

People seeking PEP may present at an emergency department or sexual health clinic where
starter packs of antiretroviral drugs are available. They will require follow-up within a few
days for counselling, risk review, review of side effects and to receive further prescription
of anti-retroviral drugs by an accredited HIV prescriber for one month (if appropriate).
Counselling for PEP involves exploring the known or suspected risks of HIV infection against
the risks and known side effects of one month’s antiretroviral therapy.
The risk of HIV transmission through single exposure is determined by:
•
method of exposure and its estimated risk
•
risk that the source is HIV positive, if their status is unknown
•
co-factors associated with the source and exposed individuals.
Assess risk
•
establish reason for requesting PEP
•
assess client’s potential risk of exposure to HIV by establishing date, time, and type of
exposure
•
explain relevance for further questioning if exposure was percutaneous, significant mucous
membrane or non-intact skin.
Assess exposure
116
•
determine exposure – what, when, where, whom and exact details (including contributory
factors)
•
amount of blood or body fluid involved (including trauma)
•
first aid measures applied.

Lymphogranuloma venereum (LGV)
Lymphogranuloma venereum (LGV) is an invasive genital disease caused by chlamydia
trachomatis serovars L1, L2 or L3, which results in complex and severe symptoms including
tissue destruction and ulceration. These serovars differ from other chlamydia trachomatis
serovars B - K which are known to cause urethritis and cervicitis. LGV is endemic to tropical
areas such as the Caribbean, Africa, South America, Central America and Asia. Almost all
infections reported in Australia have either been acquired from endemic areas overseas or in
men who have sex with men (MSM). There is reported high incidence of concurrent infection
with HIV, syphilis, gonorrhoea and hepatitis C. LGV may cause proctitis if the infection is
acquired through unprotected anal sex.
Transmission is by direct skin-to-skin contact with open lesions, usually occurring through
sexual contact. Lesions outside the genital area are rare but oral lesions have been reported.
Signs / symptoms
Primary stage49, 50
•
painless blister, usually three to ten days after sexual contact (sometimes up to 30 days)
•
ulceration may occur.
Secondary stage
•
systemic symptoms one to six weeks after sexual contact including inguinal
lymphadenopathy, fluctuant bubo, necrosis of the lymph nodes and abscess formation
•
anorectal symptoms include proctitis, pain, discharge, bleeding, tenesmus, constipation,
inflammation and acute haemorrhagic proctitis which is usually confined to the distal
10cm of the anorectal canal
•
fever, nausea and malaise are common.
Late or tertiary stage
•
development of chronic inflammatory lesions and lymphoedema, sinus formation,
scarring, strictures and fibrosis of the anogenital tract, lymphatic obstruction,
elephantiasis, rectal strictures and fistulae.
Investigations
•
•
Lesion
–
swab for chlamydia PCR
–
rectal or anal swab for LGV PCR (available from Pathology Queensland – Central
Laboratory (RBWH) phone 0437 082 545)
–
swab for HSV PCR.
Rectal
–
swab for chlamydia PCR
SECTION 4
2010
119
•
–
swab for LGV PCR (indicated if presenting rectal symptoms and/or positive rectal
chlamydia)
–
swab for HSV PCR
–
swab for syphilis TPPA DNA / PCR.
Serology (discuss with a MO or laboratory)
–
LGV complement fixation test (LGV-CFT). Contact laboratory prior to testing. Titres
>1:64 are highly suggestive of LGV in a client with a compatible clinical picture, while
titres <1:32 make the diagnosis unlikely.
LGV testing should be performed as a secondary test for all confirmed. Chlamydia trachomatis
rectal isolates, and for their sexual partner(s). Attempt to isolate the organism from the
lesion, the rectal mucosa or by aspiration from the enlarged nodes or bubo.

•
COC user taking a short course (<3 weeks) of antibiotics should be advised to use
additional contraception (i.e. condoms) during treatment and for seven days after

•
Clinical differentiation of conditions that cause genital ulcerative disease is inaccurate,
particularly in areas where more then one causative organism is endemic26. This is further
compounded by the presence of HIV infection which may alter clinical manifestations and
patterns of GUD occurrence. Recent evidence suggests that HSV 2 is increasing in many
populations as the main cause of GUD26. Therefore after detection of GUD (i.e. Chancroid,
Donovanosis, LGV or HSV) it is important to consider additional investigations and
treatment regimens based on local aetiology and sensitivity patterns.

Molluscum contagiosum
Molluscum contagiosum is a common benign skin disease caused by a poxvirus49. Lesions
are predominately self-limiting and spontaneously regress in immunocompetent individuals.
In the immunocompromised (i.e. people living with HIV), lesions can become extensive and
persistent51. Treatment is not essential as there are no significant abnormal complications,
however it can be requested for cosmetic reasons. The disease is transmitted by direct skin
contact and fomite transfer49.
Signs / symptoms49
Lesions
•
Generally appear 3 – 12 weeks after contact
•
Flesh coloured, discrete, smooth, firm, dome-shaped papules with central umbilication
•
most have a 3 – 5mm diameter, however giant papules (>15mm diameter) can occur
•
In adults, lesions commonly occur on thighs and buttocks
•
In people with HIV, the infection may be widespread and is common opportunistic

CLINICAL MANAGEMENT GUIDELINES
Pelvic inflammatory disease (PID)
Pelvic inflammatory disease (PID) is a range of inflammatory disorders of the female upper
genital tract which include endometritis, salpingitis, pelvic abscess and pelvic peritonitis8,32.
PID is an acute clinical syndrome often associated with ascending infection due to microorganisms such as neisseria gonorrhoeae or chlamydia trachomatis. This can be termed STI
associated PID32.
Anaerobic bacteria that are considered normal flora of the genitourinary tract (i.e. gardnerella
vaginalis, genital mycoplasms (M. hominins, M. genitalium) or enteric gram-negative rods
are sometimes associated with PID, as are gynaecological procedures such as surgery, TOP,
delivery, intrauterine contraceptive device (IUCD) insertions/removals.
The diagnosis will only be made if symptoms are identified by the client and a bimanual
examination is done on women at risk. This is especially important in symptomatic women
diagnosed with chlamydia or gonorrhoea at screening
NOs must refer to or at minimum consult a MO or authorised endorsed NP regarding all
suspected or confirmed cases of PID and acute abdominal pain.
Signs / symptoms
•
low grade PID is commonly asymptomatic
•
fever
•
nausea and vomiting
•
pain (abdominal, pelvic, bowel or bladder)
•
abnormal vaginal bleeding, irregular menstrual cycles
•
abnormal discharge (urethral, vaginal or rectal)
•
sexually transmitted infection (STI)
•
pregnancy
•
urinary symptoms (e.g. dysuria, frequency)
•
evidence of intrauterine or other gynaecological instrumentation (e.g. intrauterine
contraceptive device insertion).
Factors associated with increased risk of PID
•
young age
•
multiple partners
•
presence of bacterial vaginosis
•
history of STI
•
vaginal douching
•
new partner in previous three months
SECTION 4
2010
137
•
post-partum endometritis
•
recent history of instrumentation (i.e. TOP, IUCD insertion)
•
from areas of high STI prevalence.
Diagnosis
Diagnosis of PID is clinical and based on signs, history and examination. However, it is
important to remember that clinical diagnosis for PID is imprecise. All women with suspected
PID should have a bimanual examination.
When taking history ensure you ask about the following:
•
last menstrual period (LMP)
•
sexual activity including recent change of sexual partner(s) and previous STIs
•
contraceptive usage e.g. recent insertion of intrauterine systems (IUCS)
•
recent surgical instrumentation e.g. termination of pregnancy (TOP) and/or delivery
•
urinary symptoms
•
medication and drug allergies
•
onset, location, radiation and duration of pain
•
severity of pain and whether any treatment has been received
•
characteristics of pain e.g. acute, chronic or intermittent
•
associated symptoms e.g. nausea, vomiting, anorexia, diarrhoea, bleeding or haematuria
•
recent use of analgesia, narcotics or antibiotics
•
time of last bowel movement.
PID should be suspected if a sexually active young woman or women at risk of STI especially
experiencing all of the following symptoms:
•
pelvic or lower abdominal pain and/or tenderness of recent onset
•
dyspareunia
•
no other illness can be identified
•
has one or more of the following minimum criteria present on pelvic examination.7
Minimum criteria for suspecting/diagnosing PID
138
•
cervical motion tenderness (CMT) with bimanual palpation
•
adnexal tenderness
•
uterine tenderness with bi-manual palpation.
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
Additional criteria
The following additional criteria may support the diagnosis.
•
mucopurulent discharge from external os
•
elevated temperature (>38.3c)
•
abnormal vaginal discharge
•
presence of abundant numbers of WBC on saline wet prep
(>10 cells per high field)
•
confirmed laboratory diagnosis of chlamydia or gonorrhoea
•
elevated C-reactive protein
•
elevated ESR.
Investigations
Urethral
•
urinalysis and mid stream urine
•
urine BHCG.
Vaginal
•
high vaginal swab for M/C/S for BV or candidiasis
•
high vaginal swab for trichomonas PCR
•
high vaginal swab for wet prep/gram stain (if available)
•
pH
•
whiff test.
Endocervical
•
swab for chlamydia PCR
•
swab for gonorrhoea M/C/S.
Other
•
bi-manual examination (if not pregnant)
•
examine abdomen for rebound, tenderness and guarding
•
temperature, pulse and blood pressure
•
discuss additional STI screening.
Note: If the client declines or is unable to complete an STI screen, encourage as a minimum:
•
self-administered vaginal swab for chlamydia, gonorrhoea and trichomonas PCR
or
•
first catch urine for chlamydia and gonorrhoea PCR.
All women of childbearing age presenting with lower abdominal pain should have a urine
SECTION 4
2010
139
pregnancy test to exclude ectopic pregnancy. Negative swabs do not preclude a diagnosis
of PID. Pelvic ultrasound is usually unhelpful in establishing or excluding a diagnosis of PID.
Laparoscopy provides definitive diagnosis but may be difficult to access so diagnosis is
based on pelvic examination.
Management
Conditions requiring NO to refer to or at minimum consult with an MO or NP (if appropriate/
available):
•
suspected or confirmed diagnosis of PID
•
acute abdominal pain
•
surgical emergency e.g. appendicitis
•
persistent pain and/or symptoms following treatment
•
inability to tolerate out-patient treatment
•
recent instrumentation e.g. intrauterine device in-situ or TOP
•
complicated infection e.g. symptoms of Fitz Hugh Curtis syndrome
•
pregnancy test is positive
•
immunosuppression e.g. HIV positive client
•
abnormal findings of clinical significance
•
findings outside NOs scope of practice.
Note: NOs are recommended to refer all cases of suspected or confirmed PID to an
emergency department if a MO is unavailable for immediate consultation.
Treatment
Indicators
•
clinical diagnosis based on examination and history
•
signs and symptoms
•
laboratory confirmed diagnosis is not required to commence or continue treatment.
For mild to moderate PID (out-patient management)
•
the client should be reassessed at 72 hours
•
refer for further MO consultation or hospitalisation if there is no substantial improvement
within 72 hours.

Note:

•
Treatment regimens should be effective against N. gonorrhoeae, Chlamydia Trachomatis,
anaerobes and bacterial vaginosis as endocervical screening does not rule out an upper
reproductive tract infection.
Evidence suggests that an effective treatment for mild to moderate PID is Ceftriaxone
250mg IMI plus Doxycycline orally 100mg twice daily for 14 days with or without
Metronidazole 500mg orally twice daily for 14 days7,54. The decision to administer this
regimen with or without Metronidazole is based on clinical judgement of client risk of
anaerobic pathogens such as pelvic abscess; proven or suspected trichomonas vaginalis
and/or bacterial vaginosis, or history of gynaecological instrumentation in the preceding
2 - 3 weeks. Currently this is not an approved regimen so a NO is required to discuss first
with a MO.
Recent studies indicate that a regimen of Azithromycin and Ceftriaxone or Doxycycline
and Ceftriaxone (doses as above) for PID may be equivalent in efficacy for first-line
treatment of mild PID. However, additional research is required before recommendations
can be made54.
COC user taking a short course (<3 weeks) of antibiotics should be advised to use
additional contraception such as condoms, during treatment and for seven days after
antibiotics have been stopped.
Women with an IUCD insitu should be referred to a MO.

Proctitis
Proctitis is indicated by the presence of anal discharge, blood and/or mucous in stools, and
pain during defecation. Proctitis caused by sexually transmitted organisms is usually caused
by Neisseria Gonorrhoeae or the herpes simplex virus, however Chlamydia trachomatis
is increasingly implicated in MSM. Recently, Lymphogranuloma venereum (LGV) has been
identified as a cause of acute proctitis in MSM in Australia, Europe and North America.
Signs / symptoms
•
rectal discharge, itch and/or soreness
•
blood, pus and/or mucus in stools or on underwear
•
discomfort or bleeding on defecation or in association with anal penetration.
The following are possible causes of Proctitis:
•
Chlamydia Trachomatis
•
Neisseria Gonorrhoeae
•
Trichomonas vaginalis
•
Herpes simplex virus
•
Human papilloma virus
•
Treponema Pallidum
•
Lymphogranuloma venereum
•
Enteric pathogens/parasites such as Giardia Lamblia, Entamoeba Histolytica,
Campylobacter, Shigella
•
Inflammatory/Irritable Bowel Syndrome
•
Rectal and/or bowel abnormalities such as malignancy, benign growths or polyps
•
Diverticular disease
•
Anal fissure, tear, sinus or fistula
•
Foreign bodies
•
Trauma.
When taking history be sure to ask about the following:
•
Sexual, medical and surgical history and for females a gynaecological and menstrual
history
•
blood, pus and/or mucus in stools or on underwear
•
discomfort/pain or bleeding on defecation
•
discomfort/pain or bleeding during or after anal intercourse
SECTION 4
2010
149
•
associated symptoms e.g. tenesmus, pruritus, pain or fever
•
previous history of STIs and treatment history
•
recent change of sexual partner or symptomatic partner
•
recent increase in anal intercourse
•
recent overseas travel or sexual contact with person from endemic country
•
use of foreign objects/sex toys for anal penetration
•
change in bowel motions/habits.
Examination
•
palpate inguinal lymph nodes for enlargement and or tenderness
•
examine perianal region for colour, discharge, erythema, lesions, ulcers, rashes,
excoriation, trauma or abnormalities
•
perform proctoscopy and examine rectal mucosa for colour changes, appearance,
lesions, ulceration, fissures, discharge, inflammation, masses or abnormalities.
Investigations
Perform investigations based on risk assessment, clinical findings and local policy.
•
blood pressure, TPR
•
rectal mucosa swabs for:
•
150
–
gonorrhoea PCR or culture and sensitivity (C/S)
–
chlamydia PCR. If positive also perform LGV serotype (PCR).
–
swab for HSV PCR (if indicated)
–
swab for Treponemal PCR for syphilis
–
press slide and GUMP for donovanosis
–
consider punch biopsy for lesions that are atypical or unresponsive to treatment
(particularly in clients with HIV).
serology
–

–
HIV.
•
if diarrhoea is present take a stool sample for microscopy, culture and sensitivity (M/C/S)
•

proctitis associated with painful ulceration can suggest herpes simplex virus, so
presumptive anti-viral treatment should also be given.
Laboratory confirmed diagnosis:
•
if rectal PCR positive for chlamydia, perform LGV testing and consult with a MO.

Syphilis
Syphilis is caused by the bacterium Treponema pallidum49. T. pallidum is a member of the
spirochaetaceae family which is responsible for Yaws (T. Pertenue) and Pinta (T. Carareum).
Syphilis can be categorised into congenital infection and acquired infection.
Congenital infection is acquired through transplacental infection or during delivery.
Acquired infection is acquired by direct contact with infectious exudate from associated skin
lesions (chancre) and mucous membranes during sexual contact. Transmission may occur
within the injecting drug user population. Acquired infection can be divided into two further
categories:
•
Early infection of <2 years (which includes primary, secondary and early latent infection)
•
Late syphilis of >2 years duration (which includes late clinical stage such as tertiary or
late latent infection).
Signs / symptoms
Primary syphilis
The infecting organism disseminates through the body during this time.
•
10 - 90 days incubation (three weeks on average)
•
skin lesions (chancres):
–
painless ulceration
–
typically presents as a single painless lesion with raised border and indurated clean
base
–
atypical presentations and/or multiple lesions can occur due to
co-infection with HIV, secondary infection or application of topical medication
–
may occur at extra-genital point of treponemal inoculation i.e. fingers, nipples or lips
–
painless regional lymphadenopathy may be present.
Secondary syphilis
Signs and symptoms may appear and regress at intervals over a two year period.
•
Cutaneous or mucosal rash49
•
chancres may still be evident in secondary syphilis
•
flu-like illness
•
skin lesions
•

QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES

–
wart-like lesions (condylomata lata).
•
generalised lymphadenopathy
•
loss of eyelashes and outer-third of eyebrows
•
sometimes alopecia or ‘moth-eaten’ appearance beginning at the occipital scalp
•
systemic dissemination
•
manifestation of neurological involvement (more common in HIV infected clients).
Latency
After the secondary stage there is typically a long period of latency during which the only
finding is positive syphilis serology. This interval may be shorter in those who are HIV
positive.
Tertiary syphilis
Tertiary syphilis is rare but should be excluded in anyone presenting with neurological signs
who has positive syphilis serology and no history of treatment. Management should always
be in consultation with a specialist MO.
Testing
Testing should occur in the following circumstances:
•
known contact of syphilis
•
genital ulceration
•
presence of other STI
•
identified risk through unprotected intercourse including oro-genital
•
symptoms characteristic of second or latent syphilis
•
sexual health check and routine antenatal testing.
Investigations
Testing for syphilis should not occur in isolation. Screen for all STIs and if syphilis is
suspected contact the Syphilis Register on 1800 032 238 for advice.
Serology
•
syphilis
•
HBV
•
HIV.
SECTION 4
2010
167
Lesion
•
dark ground microscopy (if available)
•
treponemal PCR swab (if available). Discuss with MO and laboratory prior to collection.
Serology
Most syphilis is diagnosed on the basis of serology. In approximately 75% of cases of primary
chancres, serology is positive at the time of presentation. However, negative serology in a
client with a genital ulcer does not exclude syphilis. Dark-field microscopy and PCR testing
can be used if available.
Non-specific (non-treponemal) tests (RPR and VDRL) usually become reactive six weeks after
infection. RPR is the most common test to assess disease activity and monitor response to
treatment. In early syphilis, there will be a four-fold
(2 titre) drop in the RPR titre over 6 - 12 months following adequate treatment. Even without
treatment, the RPR titre gradually declines over many years.
Specific treponemal tests (EIA, TPPA and FTA-ABS) remain positive ‘for life’ in most cases,
regardless of treatment. Some of these tests e.g. FTA - may detect infection at an earlier stage
than RPR. RPR plus a specific treponemal test is typically used for screening purposes to
detect infections where the RPR may have become negative over time. Specific tests cannot
be used for monitoring the efficacy of treatment.
Dark-field microscopy
This allows demonstration of spirochaetes from primary chancres or mucous membrane
lesions of secondary syphilis. The lesion is cleaned with saline, squeezed gently, and a drop
of expressed exudate is placed into a drop of saline on a glass slide. If dark-field microscopy
is immediately available, motile treponemes can be seen directly in the wet preparation.
If dark-field microscopy is not available, allow the sample to dry, then send the slide to a
laboratory for detection of treponemes by an immunofluorescent technique (however this
test is not commonly available in Australia). Check with your local laboratory to confirm
whether dark-field microscopy is available.
PCR testing for Treponema pallidum
PCR testing of a swab taken from a genital ulcer or mucous membrane lesion has good
sensitivity and specificity. In Queensland Health laboratories, this test will only be performed
if it is accompanied by a blood specimen for syphilis serology. In the Northern Zone, the test
is performed as part of a multiplex PCR test for GUMP.

Benzathine Benzylpenicillin (Pan Benzathine Penicillin) injection
To minimise discomfort:
•
reconstitute each 900mg in a minimum of 4mls of water
•
use a 5ml syringe
•
hold the vial vertically and mix well until powder is absorbed
•
prepare immediately prior to administration
•
prior to administration, warm injection (do not heat above +50oC) by rolling syringe
between palm of hands, as this may reduce discomfort for the client
•
if there is delay in administration following preparation, ensure syringe is rotated
vertically prior to administration so it mixes adequately. This will reduce obstruction of
the needle due to precipitation of the suspension
•
attach a 19 gauge or 21 gauge needle for injection to the syringe just prior to injecting
suspension, to prevent blockage of needle
•
administer in the upper/outer quadrant of the gluteus maximus and apply pressure to
the injection site at for at least ten seconds prior to administration
•
give two injections (one in each buttock).
Jarisch-Herxheimer reaction
Approximately 30% of people treated for primary syphilis and 60% of people treated for
secondary syphilis have a reaction characterised by chills, fever, arthralgias, headaches and
transiently increased prominence of lesions49. The Jarisch-Herxheimer reaction is due to the
release of treponemal constituents and usually occurs within 24 hours of starting treatment.
Advise the client that this may occur and that it can cause signs and symptoms to temporarily
exacerbate.
Signs / symptoms of Jarisch-Herxheimer reaction
•
prodromal phase with aches and pains (<4 hours)
•
rigor or chill (4 - 8 hours)
•
flush with temperature peak and hypotension (8 hours)
•
falling temperature, back to normal (lasting up to 12 hours)
•
fever, sweats, shivering, muscle/joint pains, sore throat or headache
•
sudden worsening of local lesion (i.e. chancre or rash)
•
fast pulse or feeling faint (postural hypotension).
Jarisch-Herxheimer reaction can cause premature labour in some women and fetal distress
during the second half of pregnancy.
Management
•
174
advise client in advance of possible reaction(s)
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
•
manage with rest and fluids
•
aspirin or paracetamol - two tablets four hourly (as required). Do not exceed four doses
(eight tablets) in 24 hours. Aspirin should not be given during pregnancy
Note: COC users taking a short course (<3 weeks) of antibiotics should be advised to use
additional contraception such as condoms, during treatment and for seven days after
antibiotics have been stopped
Penicillin remains the preferred treatment for all stages of syphilis. Serology should be
repeated at the time of initial treatment as this will provide a baseline RPR for monitoring
response to treatment.
Treatment of early syphilis in clients allergic to penicillin
This includes clients who have a documented cutaneous reaction or history of
hypersensitivity to Penicillin.
Use Doxycycline 100 mg twice daily for 14 days. Doxycycline should not be used in pregnancy
(category D in pregnancy).
Consideration could be given to desensitisation in those who are Penicillin allergic (especially
in pregnancy).
Erythromycin should not be used during pregnancy as it may not prevent congenital
syphilis. Pregnant clients who are allergic to Penicillin pose difficult problems. If Penicillin
desensitisation is not possible, the remaining treatment options are Azithromycin or
Ceftriaxone. However, the baby will always require additional treatment and careful follow-up
if a non-penicillin treatment is used during pregnancy.
Penicillin allergic clients should be managed in consultation with an experienced infectious
disease or sexual health clinician.
Late latent syphilis (>2 years duration)
People with late latent syphilis are not sexually infectious. Vertical transmission can still
occur even though it’s less likely more than two years after initial infection. The principal goal
of treatment is to prevent late complications.
Lumbar puncture in late latent syphilis
T. Pallidum invades the CNS in 25% of clients with syphilis (irrespective of HIV status).
Infection is effectively cleared in about 75% of these clients, while the remaining 25%
harbour organisms in their CNS which can lead to symptomatic neurological disease in
late syphilis. Symptomatic neurosyphilis in secondary or late syphilis is a rare occurrence,
probably due to widespread use of antibiotics for other reasons.
Lumbar puncture is not necessary in secondary or latent syphilis unless there is clinical
evidence of neurological involvement. Seek specialist advice if in doubt.
All clients with positive syphilis serology who have neurological symptoms or signs of late
syphilis should undergo lumbar puncture and CSF examination.
There is no comprehensive test to diagnose neurosyphilis, so all test results should be

serological test for syphilis in CSF. When reactive in the absence of significant contamination
of CSF with blood, it is considered diagnostic of neurosyphilis. However, the VDRL-CSF may
be non-reactive in clients with neurosyphilis. CSF FTA-ABS is less specific but highly sensitive,
and if negative, neurosyphilis is usually excluded. The CSF leucocyte count is usually elevated
(>5 WBC/mm3) with protein raised and glucose reduced. Seek specialist advice in the management of symptomatic late syphilis and neurosyphilis.
Treating neurosyphilis
Seek specialist advice. Recommended treatment is Benzyl Penicillin 1.8grams IV (depending
on body weight), four hourly for 15 days.
Pregnancy and congenital syphilis
If a client has history of adequate treatment for syphilis with serological follow-up, and reinfection is unlikely, avoid re-treatment and serological examination of the infant. In areas of
high prevalence, it may be necessary to screen for syphilis in pregnancy. Testing should occur
during presentation at the third trimester and time of delivery.
Vertical transmission of syphilis in untreated women is possible but tends to decrease in
probability over time. Pregnant women should be treated with Penicillin at the same dosage
for non-pregnant women at a similar stage of infection. Seek specialist advice about females
allergic to Penicillin. Tetracyclines should not be used in pregnancy and Erythromycin does
not reliably treat an infected foetus.
Contact the Queensland Syphilis Register on 1800 032 238 if a pregnant woman has positive
syphilis serology.
Treatment is adequate if:
•
completed before 29 weeks
•
there is a documented four-fold (two titre) drop in RPR before or at time of delivery.
A baby is at high risk if:
•
the mother has primary or secondary syphilis genital sores at time of delivery
•
the mother was treated with a drug other than Penicillin or treatment was inadequate
•
treatment of mother was within four weeks of delivery
•
the mother’s RPR is greater than or equal to 1:64, or is not falling
•
examination of the baby shows signs of congenital syphilis
•
the mother’s RPR at delivery shows inadequately treated or previously undiagnosed
syphilis.
Any high risk baby needs a lumbar puncture and CSF examination for white cells, protein and
VDRL.
If CSF examination is abnormal:
Benzyl Penicillin 50 mg/kg IM or IV daily in two divided doses for ten days, or Procaine
Penicillin 50 mg/kg IM daily for ten days.
176
QUEENSLAND SEXUAL HEALTH
CLINICAL MANAGEMENT GUIDELINES
If CSF examination is normal:
•
the baby needs single dose treatment at birth.
In the following circumstances, the baby is at low risk and requires only a single dose
treatment of Benzathine Penicillin (Bicillin LA) 50 mg/kg IM at birth.
•
the mother had no syphilis serology performed during pregnancy but there is moderate
- high prevalence of syphilis in her community (e.g. remote Indigenous community). The
mother should have an RPR performed at the earliest opportunity to ensure the baby is
not at high risk
•
the mother was treated for syphilis with Penicillin during pregnancy, treatment was
completed before 36 weeks with an adequate response
•
the baby needed a lumbar puncture but the result is normal.
The baby needs no investigation or treatment if:
•
the mother had all antenatal and pregnancy bloods taken and all syphilis antibody
screens EIA or TPPA or FTA-ABS and RPR are non-reactive
•
the RPR during pregnancy and just prior to pregnancy are stable low titres
•
the mother has a documented record of past treatment.
If in doubt consult a paediatrician or infectious disease clinician. A useful reference is the
Australian Society of Infectious Diseases and the Royal Australian and New Zealand College
of Obstetricians and Gynaecologists. Phone (02) 9256 5475 or email [email protected]
Follow-up for babies
The mother needs follow-up in all cases where she may have had syphilis during pregnancy.
Babies fall into four groups for follow-up:
•
high risk with abnormal CSF - repeat RPR and lumbar puncture at six months and review
by paediatrician
•
high risk with normal CSF but confirmed Congenital Syphilis - RPR at six months and
review by paediatrician
•
high risk with normal CSF and no signs of Congenital Syphilis - follow-up the mother only
•
low risk or no treatment needed - follow-up mother only.

–
repeat serology at three, six and 12 months
–
discuss results of follow-up serology with a MO
–
•
after adequate treatment of early syphilis, a four-fold (two titre) drop in RPR titre should
occur over 6 -12 months. Quantitative RPR or VDRL tests should be taken at six, 12 and 24
months following treatment. If at six months the RPR has fallen by at least two titres and
is 1:16 or less, further follow-up may not be necessary unless reinfection is likely
•
re-treatment should be considered if signs/symptoms persist or recur, if there is a
sustained four-fold increase in the titre of RPR or VDRL or if the initial RPR or VDRL titre
fails to show a four-fold decrease within 12 months

Tinea cruris
Tinea cruris is a superficial fungal infection of the groin and adjacent skin caused by
dermatophytes which cause the skin to become red and itchy. Common etiologic agents for
tinea cruris are trichophyton rubrum and epidermophyton floccosum, while trichophyton
mentagrophytes and trichophyton verrucosum are also known to be involved55. Infection
is more common in men than women and frequently occurs in young men in association
with tinea infection of the feet32 (known as tinea pedis). Tinea cruris can be spread by close
contact, fomites and autoinoculation and is common in hot or humid climates or associated
with wearing tight-fitting or wet clothing/underwear55.
Signs / symptoms
•
macular erythematous scaling, itchy red rash in groin extending to inner thighs, and may
include buttocks, lower back and abdomen
•
edges are sharply demarked with a prominent annular rim
•
rash may have central clearance with satellite lesions
•
pustules of fungal folliculitis
•
autoinoculation from feet can sometimes occur.

Trichomoniasis
Trichomoniasis is caused by the motile flagellated protozoan Trichomonas Vaginalis7, 32.
Infection can result in vaginitis and urethritis in females and urethritis in males. Infection is
relatively uncommon in urban Australian settings, but is prevalent in Indigenous populations
of Australia and countries such as Africa, Asia, and Latin America. Transmission is
predominately through sexual contact but perinatal transmission can also occur. Co-infection
with other STIs is common.
Signs / symptoms
Female
Symptoms can persist for years. About 10 - 50 % of females can remain asymptomatic.
•
vaginal discharge
–
copious greenish/yellow which is sometimes frothy
–
‘fishy odour’ which is more noticeable during menstruation or after sexual
intercourse
–
wet prep reveals trichomonads.
•
Vaginitis or vulvitis
•
vulval irritation
•
cervicitis (strawberry cervix)
•
dysuria
•
dyspareunia
•
sometimes minimal or no symptoms.
Male
Infection is usually asymptomatic and short-lived in comparison to female infection (i.e.
months as opposed to years).
•
dysuria
•
urethral discharge (usually scant or moderate, rarely copious or purulent)
•
urethral irritation
•
urinary frequency
•
prostatitis (rare)
•
balanoposthitis (rare).
SECTION 4
2010
183
Investigations
There is no reliable test available for males.
Females presenting with persistent, offensive and irritating vaginal discharge should be
tested. This should be a routine part of any sexual health check in high prevalence areas
such as remote Indigenous communities. It is sometimes picked up by an incidental finding
on a pap smear. Ensure that women with a vaginal discharge have a vaginal and cervical
examination.
Vaginal
•
swab for M/C/S
•
swab for PCR
•

•
wet preparation (onsite if available)
•

For microscopy (wet preparation) and culture, transport using Amie’s or Stuart’s medium with
added charcoal.
•
take high vaginal swab for wet prep and culture
•
treat contacts of females with trichomonas or contacts of males with urethral symptoms
(in the absence of gonorrhoea or chlamydia) empirically for trichomonas
•
trichomonads may be seen on a pap smear, however there is a significant
•
rate of false positives. Confirm diagnosis by microscopy and culture of vaginal discharge
•
PCR test for trichomonas is only available through Queensland Health Pathology Service
on specimens from remote communities. Transport a high vaginal swab in a dry sterile
container at room temperature for PCR testing. Theoretically, when validated, the PCR
test should also allow reliable testing of first catch urine specimens for Trichomonas
Vaginalis in males and females.

Urinary tract infection (UTI)
Acute uncomplicated urinary tract infections (UTI) are usually caused by a single microorganism with the commonest pathogen being Escherichia Coli32.
Less common causes include:
•
gram negative organisms i.e. pseudomonas
•
gram negative bacilli i.e. enterobacter, klebsiella or proteus
•
gram positive cocci i.e. staphylococcus, streptococcus or enterococcus.
UTI is common during pregnancy and has been associated with increased risk of
pyelonephritis, premature delivery and fetal mortality56. Group B streptococcus (GBS) is
a frequent cause of asymptomatic bacteriuria, urinary tract infection in pregnant women,
clients with diabetes or clients with weaker immune systems.
Uncomplicated UTIs are unusual in healthy young men32.
Signs / symptoms
•
urinary frequency or urgency
•
dysuria
•

Note: Empricial treatment with antibiotics is recommended in otherwise healthy females
presenting with symptoms/signs of uncomplicated lower UTI. In females with symptoms of
vaginal itch or discharge, explore alternative diagnoses and consider pelvic examination prior
to treatment.
Urinalysis and MSU
•
urinalysis via dipstick is recommended for diagnosis of bacteria in females with limited
urinary symptoms. Empirical treatment is still indicated if symptomatic with negative
urinalysis
•
some evidence suggests MSU for M/C/S is not necessary for uncomplicated UTI in nonpregnant females, prior to initiating empirical treatment
•
MSU for M/C/S is recommended if:
–
unresponsive to syndromic management of uncomplicated UTI
–
symptoms return 2 - 4 weeks post syndromic treatment
–

Vaccination - Hepatitis A (HAV)
Hepatitis A is an acute infection of the liver caused by the hepatitis A virus (HAV)1. HAV is a
picornavirus [33] that is now classified as a hepatovirus1.
HAV is transmitted by the faecal-oral route by either person-to-person contact or through
contaminated food or water. The incubation period for hepatitis A is 15 to 50 days and it
is able to survive on hands and in the environment for considerable periods of time. It is
important to remember for purposes of infectivity and prevention that HAV can be excreted
in faeces for up to 2 weeks prior to onset of illness and for approximately 1 week after
presentation of illness1. The majority of infections are sub clinical and self limiting (especially
in children) and complications are rare. HAV does not result in chronic infection or chronic
liver disease7.
HAV is endemic at high prevalence rates in many developing countries with majority of the
community infected at a young age1. In developed countries risk factors include: travel to
a high prevalence country, institutional settings such as child care centres, MSM, IDU and
occasional outbreaks related to poor hygiene, food handling and contaminated water.1, 32
Vaccination against HAV should be offered to all clients assessed to be at risk factors of
infection and tested negative HAV Total Ab.
Management
•
check protocols and availability of equipment and drugs necessary for management of
anaphylaxis prior to each vaccination1
•
advise the client of risks and benefits of vaccination and preventable diseases1
•

Vaccination - Hepatitis B (HBV)
Hepatitis B infection is caused by the hepatitis B virus (HBV), a virus that contains a partially
double stranded DNA1, 32. HBV has an outer surface envelope that contains hepatitis B surface
antigen (HBsAg) and a core containing hepatis B core antigen (HBcAg). HBcAg is not detected
in the blood but excess HBsAg circulates in the blood and is used in HBV screening and
detection of infectivity. HBeAg is also produced by HBV and excreted into the blood. Presence
of HBeAg in serum along with HBsAg indicates an acute infection or ongoing increased
infectivity. Hepatitis B surface antibodies (HBsAb) are produce in response to HBsAg and
indicate immunity due to past infection or vaccination.
HBV prevalence rates varieties across the world and within some countries1, 32. It is important
to understand prevalence rates when screening and offering vaccination in order to ensure
appropriate pre test information. HBV is transmitted perinatally and in early childhood from
close contact in developing countries with high prevalence. But in developed countries
such as Australia the main mode of transmission is from adult exposure to infectious blood
or body fluids (semen, vaginal secretions) by sexual contact or percutaneous routes (e.g.
injecting drug use)1, 7.
Vaccination against HBV should be offered to the following:
•
anyone assessed to be at risk of HBV
•
anyone with HBsAb <10u/L with history of no prior completion of vaccination schedule1
•
opportunities vaccination for all clients of sexual health services
•
SIW and their partners
•
Household and sexual contacts of people who live with acute and chronic HBV as well as
•
members of families who have migrated from high prevalence countries
•
Men who have sex with men and their contacts
•
IDU and their contacts
•
Persons with chronic liver disease and/or HCV
•
Haemodialysis clients, HIV-positive clients and other immunosuppressed clients
•
Health-care workers
•
Recipients of blood/blood products, persons who have sustained a needle stick injury,
sexual
•
assault victims, and persons from areas of endemic Hepatitis B infection7
•
Other at risk groups as outlined in NHMRC (Current Version) The Australian Immunisation
Handbook
Management
•
check protocols and availability of equipment and drugs necessary for management of
anaphylaxis before each vaccination1 as per The Australian Immunisation Handbook and
DTP-SRH

Vaccination – HPV
There are more than 100 genotypes of Human papilloma virus (HPV) with more than 30 that
are known to infect the external and internal anogenital area and may present as genital
warts7. The most common genotype that cause genital warts on the skin are Type 6 and
11, high risk HPV types (16, 18, 31, 33, 35) are strongly associated with cervical changes,
neoplasias7 and other oncogenic anogenital infections. Majority of anogenital HPV infections
are asymptomatic, unrecognised or subclinical in presentation7. The majority of HPV
infections are believed to spontaneously regress but infections can persist32. A persistent
infection with high risk HPV types is the most predictive factor in progression to squamous
intraepithelial neoplasia7, 32. HPV vaccination is designed to help prevent infection with
specific HPV genotypes and protect against persistent infection.
Offer vaccination for:
•
risk of HPV infection
•
prevention of cervical, vulvar, vaginal cancer, precancerous or dysplastic lesions, genital
warts, infection caused by HPV types 6, 11, 16, 18 in females 9-26 yrs and prevention of
infection caused by HPV types 6, 11, 16, 18 in males 9-15 yrs.
Note:
•
pre-vaccination HPV screening is not recommended
•
vaccination for HPV should not occur in isolation. Discuss pap smear and additional STI
screening with client.
National HPV Vaccination Program39
The Australian Government is funding the Human Papillomavirus (HPV) vaccine Gardasil® to
girls aged 12 and 13 years, through a school-based program, on an ongoing basis as part of
the National Immunisation Program.
Note:
•
HPV vaccine is registered for males aged 9 - 15 years, however it is not funded for males
under the National HPV Vaccination Program39
•
HPV vaccine is not approved for use in females aged < 9 and is registered but not funded
for women > 26 years or males aged < 9 or > 15 years.
Regimens
•
Non DTP-SRH endorsed NOs are not authorised to administer this regimen and must
refer to a DTP–SRH or immunisation endorsed NO, endorsed NP or MO.
•
DTP–SRH or immunisation endorsed NO may progress if within scope of practice and
competence. For all other cases consult an endorsed NP or MO.
•

The National Human Papillomavirus (HPV) Vaccination Program Register
The Australian Government has developed a national HPV register which collects confidential
data to evaluate the impact of the HPV vaccination program against cervical cancer rates,
issues reminders to complete vaccination course, issues certificate of completion and
provides a mechanism to contact recipients if a booster is required at a later date.
Vaccinated females aged 18 - 26 years are not required to provide their details, but can elect
to have their details included in the HPV register. Information is collected on a consent form
at time of vaccination, then forwarded to the HPV register.
