Abstract

<p><strong>SETTING: </strong>The impact of the human immunodeficiency virus (HIV) on multidrug-resistant tuberculosis (MDR-TB) treatment outcomes in sub-Saharan Africa, where extensive rollout of highly active antiretroviral therapy (HAART) has occurred, remains unclear.</p>

<p><strong>OBJECTIVE: </strong>To compare the time to initial culture conversion among patients with and those without HIV infection in a setting of individualized MDR-TB care in Botswana.</p>

<p><strong>DESIGN: </strong>Prospective cohort study of MDR-TB patients receiving ambulatory, integrated TB-HIV care at two public clinics in Botswana. The time to culture conversion was compared by HIV status using Cox proportional hazard ratios (HRs).</p>

<p><strong>RESULTS: </strong>A total of 40 HIV-infected and 30 non-HIV-infected patients with MDR-TB and follow-up cultures were identified. The median time to initial culture conversion was 78 days (interquartile range [IQR] 42-186) for HIV-infected and 95 days (IQR 70-133) for non-HIV-infected individuals (log rank P &gt; 0.5; unadjusted HR 0.9, 95%CI 0.5-1.5). Adjusting for age, sex, treatment history and number of active anti-tuberculosis drugs did not change this result (adjusted HR 0.8, 95%CI 0.4-1.4).</p>

<p><strong>CONCLUSION: </strong>We found no difference in the proportion of or time to initial sputum culture conversion between an HIV-infected and a non-infected cohort of MDR-TB patients in Botswana, suggesting that outcomes may be comparable in similar settings with access to individualized anti-tuberculosis treatment and HAART.</p>
