ABSTRACT
<p><b>OBJECTIVE</b>To investigate the risk factors attributable to tuberculosis-related deaths in areas with human immunodeficiency virus (HIV) infection epidemics.</p><p><b>METHODS</b>A prospective cohort study of newly registered patients in tuberculosis (TB) dispensaries in six representative Chinese provinces was conducted from September 1, 2009 to August 31, 2011. Risk factors for TB-associated death were identified through logistic regression analysis.</p><p><b>RESULTS</b>Of 19,103 newly registered pulmonary TB patients, 925 (4.8%) were found to be HIV-positive. Miliary TB and acid-fast bacillus smear-negative TB were more common among these patients. Out of a total of 322 (1.7%) deaths that occurred during TB treatment, 85 (26%) of the patients were co-infected with HIV. Multivariate analysis revealed that HIV infection was the strongest predictor of death [adjusted odds ratio (aOR) 7.86]. Other significant mortality risk factors included presentation with miliary TB (aOR 4.10; 95% confidence interval 2.14-7.88), ⋝35 years of age (aOR 3.04), non-Han ethnicity (aOR 1.67), and farming as an occupation (aOR 1.59). For patients with TB/HIV co-infection, miliary TB was the strongest risk factor for death (aOR 5.48). A low CD4 count (⋜200 cells/µL) (aOR 3.27) at the time of TB treatment initiation and a lack of antiretroviral therapy (ART) administration (aOR 3.78) were also correlated with an increased risk of death.</p><p><b>CONCLUSION</b>Infection with HIV was independently associated with increased mortality during TB treatment. Offering HIV testing at the time of diagnosis with TB, early TB diagnosis among HIV/acquired immunodeficiency syndrome patients, and the timely provision of ART were identified as the key approaches that could reduce the number of HIV-associated TB deaths.</p>
