Risk factors and outcome of human immunodeficiency virus-infected patients with sporadic multidrug-resistant tuberculosis in New York City
Abstract:SETTING: An 880 bed university teaching hospital in New York City.
OBJECTIVE: To assess risk factors and outcome for sporadic cases of multidrug-resistant tuberculosis (MDR-TB) in persons with human immunodeficiency virus (HIV) infection.
DESIGN: In a retrospective cohort analysis, 13 HIV-positive patients with MDR-TB (cases) diagnosed between January 1991 and December 1993 were compared to 31 HIV-infected patients with susceptible or single drug-resistant tuberculosis (controls) diagnosed during the same time period to assess for differences in risk factors and outcome.
RESULTS: Risk factors for MDR-TB included homosexual contact as a risk for HIV transmission, prior antiretroviral therapy and Pneumocystis carinii prophylaxis. Fatality rates were 62% for MDR-TB patients and 26% for controls (P < 0.04). The median survival time was 5.8 months for cases and 9.8 months for controls. Risk factors associated with death included multidrug-resistance and CD4-lymphocyte counts below 200.
CONCLUSION: Sporadic MDR-TB infection in HIV-infected patients is associated with increased morbidity and mortality compared to infection with susceptible or single-drug-resistant TB. The median survival for HIV-infected patients with MDR-TB in this study is, however, two to three times longer than previously reported in MDR-TB outbreaks.
