HIV-positive patients treated for multidrug-resistant tuberculosis: clinical outcomes in the HAART era.

2012 
SETTING: Multidrug-resistant tuberculosis (MDR-TB) and the human immunodeficiency virus (HIV) pose two of the greatest threats to global tuberculosis (TB) control. Given expanding global access to antiretroviral therapy (ART) and second-line TB drugs more data are needed on experiences treating MDR-TB and HIV co-infection in resource-poor settings. OBJECTIVE: To describe the clinical characteristics management outcomes and factors associated with survival among HIV-positive individuals receiving treatment for MDR-TB. DESIGN: This was a retrospective case series of 52 HIV-positive individuals receiving treatment for MDR-TB in Lima Peru. We used Cox proportional hazards regression models to identify risk factors for mortality. RESULTS: A total of 31 (57%) of the cohort died on treatment with the majority of deaths due to MDR-TB. Low baseline weight predicted a three-fold increased rate of death (aHR 3.1 95%CI 1.5-6.7) while individuals receiving highly active ART experienced a significantly lower rate of death compared to those who were not (aHR 0.4 95%CI 0.2-0.9). CONCLUSION: Early ART is likely a key component of effective MDR-TB management in co-infected individuals.
