Risk Assessment: Women


NEW question 
◦ "Is it possible that any of your sex partners in
the past 12 months had sex with someone
else while they were still in a sexual
relationship with you?"
Douching may increase risk of BV, some STIs,
and HIV

Retesting Recommendations:




Retest all women and men with CT or GC 3
months after treatment
If client returns earlier than 3 months, consider
retest
If client does not return for retesting at 3
months, retest when possible
Test of cure is not recommended, except in
pregnancy, compliance is in question, or
symptoms persist

Mycoplasma genitalium



Sexually transmitted pathogen
Associated with acute and persistent
non-gonococcal urethritis (NGU) in
men, endometritis in women
Insufficient evidence for infertility,
ectopic pregnancy, adverse birth
outcomes
• Diagnostic test in development
• Azithro superior to doxy for M. genitalium
urethritis: 82% vs 39%
• Moxifloxacin effective for persistent NGU
caused by M. genitalium
52
Urethritis
Common Infectious Causes


53
Urethritis Diagnosis
Exam findings:
o Purulent discharge
Stat laboratory:
o Gram stain exudate:  5 WBC/HPF
or intracellular GNDC
o Positive LE on urine dip
o  10 WBCs/HPF on first void urine

Urethritis Treatment
Initial episode, uncomplicated:
 Treat for both GC and CT unless GC ruled
out
 Azithromycin efficacy better for M.
genitalium
Persistent infection:
 If noncompliance or re-infection, repeat
treatment with standard therapy
 Consider trichomonas, doxy-resistant
ureaplasma, prostatitis, non-infectious
etiologies
CDC 2010 STD Treatment Guidelines

55
Persistent NGU Treatment
Recommended regimens:
Metronidazole 2 g orally in a single dose
OR
Tinidazole 2 g orally in a single dose
PLUS
Azithromycin 1 g orally in a single dose
(if not used for initial episode)
Moxifloxacin 400 mg PO x 7d effective for NGU

PID Treatment Issues





Emergence of QRNG
◦ Quinolones not recommended
◦ If parenteral treatment not feasible and GC prevalence
and individual risk low, FQs may be considered
Limited data: Ceftriaxone 250 mg IM + azithro 1g PO q
wk x 2
No oral cephalosporins are recommended
When to use metronidazole:
◦ Oral regimens only
◦ Assess for BV and if present, use metronidazole
◦ If no wet mount available, use metronidazole
Insufficient evidence to warrant removal of IUD
CDC 2010 STD Treatment Guidelines
www.cdc.gov/std/treatment
58
PID: Oral Treatment Regimens
Oral regimens:
 Ceftriaxone 250 mg IM (or other parenteral 3rd
generation cephalosporin) x 1 or
 Cefoxitin 2 g IM with probenecid 1 g orally once
PLUS
 Doxycycline 100 mg orally twice daily for 14 days
WITH OR WITHOUT
 Metronidazole 500 mg orally twice daily for 14 days

Trichomoniasis





Diagnostic testing:
◦ Aptima TV (NAAT) recently approved
◦ POC tests (Affirm VP III, OSOM Trich Rapid Test*)
◦ Trich on Pap may need confirmation, liquid cytology
more specific
Consider selective screening
Consider retesting women 3 months after treatment
Antimicrobial resistance significant (5-10%)
Treat all recent sex partners; consider EPT

Trichomonas Screening?


Screening rationale is based on:
 High prevalence (STD clinics and other
settings)

Trichomoniasis Testing and Screening
Recommendations



Test women with vaginal discharge
Screening recommended for HIV+ women
Consider screening in those at high risk
for infection:
◦
◦
◦
◦


new or multiple partners
history of STIs
exchange sex for payment
use injection drugs
Consider retest in 3 months
NAATs preferred test for males

Trichomoniasis Treatment
Recommended regimen:
 Metronidazole 2 g PO x 1
 Tinidazole 2 g po x 1
Consider treating HIV-infected women:
 Metronidazole 500 mg PO BID x 7d
Alternative regimen:
 Metronidazole 500 mg PO BID x 7d
Recommended regimen in pregnancy:
Metronidazole 2 g PO x 1
Note: Vaginal therapy is ineffective
Tinidazole is a Category C drug in pregnancy

65
Trichomoniasis Treatment Failure
First treatment failure, re-treat with:
 Metronidazole 500 mg PO BID x 7 days
If repeat failure, treat with:
 Metronidazole 2 g PO x 5 days
 Tinidazole 2 g PO x 5 days
Susceptibility testing: send isolate to CDC

Bacterial Vaginosis (BV)




Additional alternative treatment regimens
Insufficient evidence to support screening high
risk pregnant women; against screening in low
risk (USPSTF)
Pre-procedural screening/treatment not
recommended
Prevention: use condoms, avoid douching
67
BV Treatment
Recommended regimens:
Metronidazole 500 mg PO BID x 7 d
Metronidazole gel 0.75% 5 g per vagina QD/BID x 5 d
Clindamycin cream 2% 5 g per vagina QHS x 7 d
Alternative regimens:
Tinidazole 2 g PO QD x 2 days
Tinidazole 1 g PO QD x 5 days
Clindamycin 300 mg PO BID x 7 d
Clindamycin ovules 100 mg per vagina QHS x 3 d
Recurrences:
Metronidazole gel 2x weekly x 4-6 weeks
Oral nitroimidazole followed by intravaginal boric acid
and suppressive metronidazole gel*

Genital Herpes

Testing:
◦ Culture, PCR for lesions
◦ Type-specific serology
◦ IgM testing not useful

Added for episodic treatment:

Suppressive therapy: prevents outbreaks and
transmission
Stronger recommendation for antiviral treatment in
late pregnancy
Famciclovir 500 mg PO x 1, then 250 mg BID x 2 d*

*Not a Family PACT benefit
71
Herpes Serology*: Recommendations



Type-specific HSV-2 serology tests may be useful:
◦ Recurrent/atypical symptoms with negative culture
◦ Clinical diagnosis without lab confirmation
◦ Patients with a partner with genital HSV
Some experts recommend serology tests:
◦ Patients who request testing or as part of
“comprehensive STI evaluation”
◦ Patients with multiple partners, HIV-infected, MSM at
high HIV risk
Universal screening NOT recommended

Genital Herpes Treatment Issues


All patients with initial genital HSV should receive
treatment
Episodic therapy for recurrent HSV:
◦ Added Famciclovir 500 mg PO x 1, then 250mg BID for 2
days



Famciclovir is less effective for suppressive
therapy than acyclovir and valacyclovir
Suppressive HSV therapy does not reduce the risk
of HIV in HSV-2 infected individuals
Antiviral therapy recommended late in pregnancy
in women with symptomatic HSV to reduce Csections

73
Syphilis




Screening: MSM, HIV+, pregnancy
Diagnosis: Reverse serology screening
challenges
Treatment: no extra dose of BIC for primary,
secondary, and early latent syphilis in HIV-infected
patients
CSF evaluation: only for neuro symptoms, tertiary
syphilis, or serology treatment failure
