Abstract [Background] With the recent decrease in the
number of tuberculosis wards and increase in elderly tuberculosis patients with comorbidities, the role of regional referral hospitals has become more important in tuberculosis
management.
[Objective] This study aimed to assess the current state
of tuberculosis management and related issues in a general
hospital lacking a tuberculosis ward.
[Methods] We retrospectively evaluated the clinical characteristics and course of patients diagnosed with tuberculosis
by culture testing from April 2008 to March 2015 at Kainan
Hospital.
[Results] A total of 146 patients (83 males and 63 females;
mean age 76, range 18 _ 94 years) were diagnosed with active
tuberculosis. Of these, 129 were diagnosed with pulmonary
tuberculosis (23 had pulmonary tuberculosis with pleurisy),
and 17 patients were diagnosed with extrapulmonary tuberculosis. The chief complains were cough/sputum in 40 cases,
fever in 24, and no symptoms in 36. Associated major
comorbidities included diabetes mellitus, chronic kidney
disease, and malignancy. In 33 patients, over 30 days were
required to diagnose tuberculosis after initial evaluation.
Drug-resistant strains were detected in 14 patients. 57 were
diagnosed with smear-positive pulmonary tuberculosis, and
66 were transferred to a tuberculosis hospital. Modify in antituberculosis therapy due to adverse reactions were reported
in 27 patients.
[Conclusion] This study evaluated the current state of
tuberculosis management in our hospital. Further educational
guidance regarding tuberculosis is needed for the hospital
staff, and is important for improvement of tuberculosis
management in our hospital.

COMPLIANCE RATE OF STANDARD TREATMENT REGIMEN AND
OPTIMAL DOSE OF ANTI-TUBERCULOSIS DRUGS
IN LATE ELDERLY PATIENTS WITH PULMONARY TUBERCULOSIS
Haruka CHINO, Eri HAGIWARA, Akimasa SEKINE, Hideya KITAMURA,
Tomohisa BABA, Takeshi SHINOHARA, Shigeru KOMATSU, and Takashi OGURA
Abstract [Purpose] The proportion of the elderly in patients
with pulmonary tuberculosis is increasing, and failure to
complete the standard treatment regimen is not uncommon
in these patients. We examined the compliance rate and problems of the standard regimen in the late elderly pulmonary
tuberculosis patients.
[Methods] We reviewed the medical records of late elderly
patients with pulmonary tuberculosis aged 75 or above who
were smear-positive and treated in Kanagawa Cardiovascular
and Respiratory Center between January 2011 and December
2014. Our retrospective study examined patient characteristics, imaging findings, laboratory results, and outcomes. The
compliance rate of standard regimen during the hospitalization period was calculated. We compared the discontinuation rate and the incidence of adverse drug reactions by
body weight equivalent doses of anti-tuberculosis drugs.
[Results] A total of 298 patients were included in this
study, and 76％ of those patients were aged 80 or above.
Anti-tuberculosis therapy was not able to be initiated for 3
patients (1％), and treatment other than standard regimen
was inevitably introduced at initiation in 21 patients. The
remaining 274 patients (92％) were administered the standard regimen. Among them, at least one medication was
subsequently discontinued for 85 patients (29％), and the
medication was changed due to drug resistance in 6 patients
(2％). The remaining 183 patients (61％) complied with the
standard regimen during hospitalization. In the comparison
by body weight equivalent dose, significantly more patients
discontinued their medication in the group using ethambutol
with a higher standard dose per weight (37％ vs. 21％,
p＝0.02).
[Conclusion] Nearly 40％ of the late elderly patients could
not comply with the standard regimen. We may need to be
more careful when calculating ethambutol equivalent dose.

TUBERCULOSIS DIAGNOSIS FOLLOWING A VISIT TO THE EMERGENCY ROOM
Takehiro YAJIMA, Daisuke JINGU, Satoshi UBUKATA, Makoto SHOJI,
and Hiroshi TAKAHASHI
Abstract [Objective] We aimed to evaluate the clinical characteristics of patients admitted to the emergency room (ER)
and diagnosed with tuberculosis.
[Method] We conducted a retrospective study of patients
aged ≧16 years admitted to the hospital between April 1980
and March 2015 and diagnosed with tuberculosis. We compared patient clinical characteristics and type of tuberculosis
between ER and non-ER patients. We also compared the
incidence of delayed diagnosis of tuberculosis between ER
patients with and without respiratory symptoms. We compared
the tuberculosis encounter rate and the time to diagnosis of
tuberculosis in ER and non-ER patients.
[Results] A total of 255 patients, including 54 ER and 201
non-ER patients were enrolled in this study. The average age
was higher in ER patients than in non-ER patients (71.7±16.3
vs. 63.3±20.3 years, p＝0.006). The reasons for visiting the
ER included acute conditions such as fracture of the lumbar
spine, acute myocardial infarction, hemorrhagic gastric ulcer,
brain infarction, and carbon monoxide intoxication, requiring
immediate treatment. The time to diagnosis of tuberculosis
in ER patients without respiratory symptoms (n＝21) was
approximately three times longer than that in patients with
respiratory symptoms (n＝33) as urgent treatment is prioritized. The tuberculosis encounter rate was 1/1,800 for patients transported by ambulance and 1/22,000 for emergency
outpatients. The time to diagnosis of tuberculosis for patients
transported by ambulance was approximately 4 _ 6 days longer than that for emergency outpatients or non-ER patients.
[Conclusion] Physicians should seek to rule out the possibility of tuberculosis in all patients admitted to the ER, even
where more urgent clinical conditions are prioritized.

LIVER TOXICITY DUE TO RIFAMPICIN MONOTHERAPY
IN LATENT TUBERCULOSIS INFECTION
Kunihiko ITO
Abstract [Purpose] To investigate the outcome of rifampicin (RFP) monotherapy for latent tuberculosis infection
(LTBI) and the incidence of RFP-induced liver toxicity.
[Method] We conducted a retrospective chart review of
patients who received RFP monotherapy as LTBI treatment
at the Daiichi Dispensary Clinic.
[Result] Of 61 patients who received RFP monotherapy, the
treatment completion rate was 88.5％, self-termination rate
was 3.3％, abandonment rate due to adverse drug effects was
8.2％ (5 cases : 3 cases of skin eruption and 2 cases of liver
dysfunction). Among the 2 cases of liver dysfunction, 1 was
not associated with abnormal alkaline phosphatase (ALP) or
gamma-glutamyl transferase (γ
γGTP) levels. Among patients
with liver dysfunction who did not discontinue RFP monotherapy, no cases of severely abnormal ALP and/or γGTP
levels were reported.
[Conclusion] The incidence of liver toxicity due to RFP is
lower than that observed with isoniazid, and liver dysfunction
due to RFP was not always associated with abnormal of ALP
and/or γGTP levels.

CASE OF TUBERCULOSIS COMPLICATIONS DURING PREGNANCY
LEADING TO AN INFECTION OUTBREAK
Emiko NISHIKAWA, Shuichi YANO, Mitsuhiro TADA, Shinichi IWAMOTO,
Toru KADOWAKI, Masahiro KIMURA, Kanako KOBAYASHI, and Toshikazu IKEDA
Abstract A 31-year-old woman developed a constant cough
during the 8th week of pregnancy and was diagnosed with
bronchial asthma. She was prescribed prednisolone and inhaled
corticosteroids. At 28 weeks of pregnancy, she showed
worsening weight loss, fever, night sweats, hoarseness, and
coughs. At 31 weeks of pregnancy, a scatter shadow and
cavitary lesions were detected on the chest radiograph. Acidfast bacilli smear test and tuberculosis (TB) polymerase chain
reaction tests yielded positive results (G-8), and she was
diagnosed with TB. Contact tracing and screening indicated
3 patients with TB onset and 18 patients with latent TB infection attributed to the initial patient, who infected a total of
36 people. In the present case, physicians were reluctant to
order a chest radiograph for fear of harming the fetus and did
not order sputum or interferon gamma release (IGRA) assay
tests either. The diagnosis was delayed by 152 days, which
was considered as a factor that caused the outbreak. The diagnosis of TB in a pregnant patient may be very challenging
because symptoms may initially be ascribed to the pregnancy, and delayed diagnosis and treatment of military TB can
lead to the death of the mother and fetus. Consequently, to
ensure early diagnosis and treatment, chest radiography and
sputum and IGRA tests are recommended for pregnant women
who have TB symptoms or are at high risk for TB.

TUBERCULOSIS ANNUAL REPORT 2014
─ (3) Case Finding and Condition of Tuberculosis Patients on Diagnosis ─
Tuberculosis Surveillance Center (TSC), RIT, JATA
Abstract Tuberculosis (TB) surveillance data from 2014
was reviewed, with respect to modes of detection, symptoms
at diagnosis, diagnostic delay, radiographic findings, comorbidity, and drug susceptibility test (DST) results.
Of the 19,615 newly registered TB cases, 82.8％ were
diagnosed while seeking care for, or during treatment of, other
illnesses.
Of the 15,149 patients with pulmonary TB (PTB), 55.9％
presented with respiratory symptoms, while 18.0％ presented
with non-respiratory symptoms, and 25.5％ were asymptomatic.
Considerable delay to the initiation of treatment following
the appearance of symptoms was observed among the younger
symptomatic smear-positive TB patients. Over 35％ of patients
aged 35 _ 59 years did not seek care for more than 2 months
after the initial appearance of symptoms.
The proportion of PTB patients with advanced or faradvanced cavitation peaked at 49.9％ among males aged 60 _
64 years, while it remained constant at around 25％ among
females in all age groups.
Positive HIV test results were obtained in 0.2％ (n＝45)
of the newly registered TB patients, among which 86.7％ were
male and 22.2％ were foreign-born. In addition, 16.3％ of
male and 10.5％ of female newly diagnosed patients had
diabetes mellitus.
Of the 10,259 culture-positive PTB patients, DST results
were available for 74.5％ of patients. In previously untreated
patients, the proportions of multi-drug resistant TB, any
isoniazid resistance, and any rifampicin resistance were 0.6
％, 4.1％, and 0.8％, respectively; among previously treated
patients, these proportions were 3.3％, 12.7％, and 3.8％,
respectively.
