Community study of the relative impact of HIV-1 and HIV-2 on intrathoracic tuberculosis
(2002) In AIDS 16(7). p.1059-1066- Abstract
- Background: HIV-1 infection is associated with an increased incidence of and mortality from tuberculosis. Few community studies have examined the effect of HIV-2 on tuberculosis. Methods: We investigated the association between HIV-1, HIV-2 and active tuberculosis in four districts (population 42 709) in Bissau, capital of Guinea-Bissau, with the highest known seroprevalence of HIV-2 infection in the world. From May 1996 to June 1998, tuberculosis surveillance and active case finding among contacts was conducted. Patients were HIV-tested, given specific tuberculosis treatment for 8 months and followed regarding mortality. Simultaneously, an HIV sero-survey was performed in a random sample of 1748 permanent residents. Results: During a... (More)
- Background: HIV-1 infection is associated with an increased incidence of and mortality from tuberculosis. Few community studies have examined the effect of HIV-2 on tuberculosis. Methods: We investigated the association between HIV-1, HIV-2 and active tuberculosis in four districts (population 42 709) in Bissau, capital of Guinea-Bissau, with the highest known seroprevalence of HIV-2 infection in the world. From May 1996 to June 1998, tuberculosis surveillance and active case finding among contacts was conducted. Patients were HIV-tested, given specific tuberculosis treatment for 8 months and followed regarding mortality. Simultaneously, an HIV sero-survey was performed in a random sample of 1748 permanent residents. Results: During a 25-month period, 366 tuberculosis cases were identified. After excluding cases among visitors to the area, and adjusting for age, the incidence of tuberculosis was 18.3 times higher (95% CI 12.9-26.0) among HIV-1-positive individuals, 13.7 times higher (9.0-20.7) among dually infected (HIV-1 and HIV-2), and 3.0 times higher (2.1-4.3) among HIV-2-infected compared with HIV-negative individuals. HIV-1 and dually infected tuberculosis patients had a higher mortality rate than HIV-negative tuberculosis patients [mortality ratio (MR) 2.68; CI 1.11 -6.48 and 2.89; CI 1.13-7.39, respectively]. The survival of HIV-2-positive tuberculosis patients was similar to that of HIV-negative tuberculosis patients (MR 1.19; CI 0.46-3.06). Conclusion: The presence of HIV-2 infection increases the incidence of tuberculosis compared with that in non-HIV-infected individuals, but does not affect tuberculosis-related mortality in the short term. In contrast, the presence of HIV-1 infection, alone or with HIV-2, has a several-fold greater impact on both the incidence of and mortality from tuberculosis. (C) 2002 Lippincott Williams Wilkins.
