Setting: Metropolitan New Orleans.
Objective: To determine the impact of human immunodeficiency virus (HIV) co-infection on the manifestations and outcome of extra-pulmonary tuberculosis (EPTB).
Design: Retrospective analysis of 136 patients diagnosed with EPTB between 1 January 1993 to 31 December 2001. Characteristics of EPTB were compared by HIV serostatus.
Results: Of those tested for HIV (n = 87), 42.5% were seropositive. Except for a higher frequency of disseminated TB among co-infected persons, the manifestations, laboratory diagnostic yield and outcome of EPTB were similar between HIV-infected and non-infected persons. The overall fatality rate was 20%; HIV-infected patients had a three-fold higher mortality compared to non-infected persons. In multivariate logistic regression analysis, factors associated with death were: HIV-seropositive (adjusted odds ratio [aOR] 5.2, 95% CI 1.1-24.65) compared to HIV-seronegative, disseminated and meningeal compared to lymphatic disease (aOR 16.87, 95% CI 12.31-123.34), and lack of TB treatment compared to receipt of TB treatment (aOR 29.23, 95% CI 14.47-191.23).
Conclusion: Manifestations of EPTB were non-specific and did not differ between HIV-infected and non-infected persons. Severe disease, lack of TB treatment and HIV co-infection were associated withdeath. Approaches are needed to reduce EPTB morbidity and mortality, especially among HIV-infected persons.
