Isoniazid prophylaxis for tuberculosis prevention among HIV infected police officers in Dar Es Salaam
Abstract
Objective: To determine the acceptability, compliance and side effects of isoniazid (INH) prophylaxis against tuberculosis among HIV infected police officers (PO) in Dar es Salaam.
Design: A nested study from a prospective follow up of a cohort of police officers.
Setting: Dar es Salaam, Tanzania.
Subjects: One hundred and forty three HIV-1 infected police officers.
Main outcome measures: Acceptance and compliance to INH prophylaxis.
Results: Of the 400 HIV-1 infected officers, 143 (35.7%) came forward for post-test counselling and HIV test results. Sixty per cent (87/143) of them accepted to be on INH prophylaxis. However only 42.5% (37/87) came forward for evaluation regarding their
suitability for INH prophylaxis. During the evaluation, eight (21.6%) of 37 otherwise asymptomatic PO were found to have active pulmonary tuberculosis (TB). Eventually only 29 PO were actually started on INH, and only 16 (55.2%) of them completed the six months course. No serious side effects were observed. One PO developed TB two months after loss to follow up before completing the six months.
Conclusions: There was low acceptability of and poor compliance with INH prophylaxis among the HIV-1 infected PO despite being educated on the benefits of prophylaxis. The prevalence of PTB among asymptomatic HIV-1 infected PO was high, and therefore persons
with HIV infection should be examined for TB even in the absence of symptoms.
