Epidemiological aspects of human immunodeficiency virus/tuberculosis co-infection in Ribeirão Preto, Brazil from 1998 to 2003OBJECTIVE: This study aimed to characterize the epidemiological profile of tuberculosis cases reported in the city of Ribeirão Preto between 1998 and 2003, according to patient HIV status, gender, age bracket and treatment outcome. METHODS: This was a descriptive epidemiological study that employed the Brazilian National Tuberculosis Notification Database as an instrument of data collection. The study sample consisted of all cases of human immunodeficiency virus/tuberculosis co-infection occurring in residents of Ribeirão Preto and reported between 1998 and 2003. RESULTS: During this period, 1273 new cases of tuberculosis were reported, 377 of which were in HIV-positive individuals, for a co-infection rate of 30%. Of the cases of co-infection, 76% were in men, and the majority occurred in individuals in the 20-59 age bracket. In terms of treatment outcome, cure was achieved in 52%, treatment abandonment was reported in 11%, and death occurred in 32%. The predominant clinical form of tuberculosis was the pulmonary form, which accounted for 58% of the cases. CONCLUSION: A high prevalence of co-infection was observed in the community studied. The treatment outcomes seen among the cases in our study sample underscore the need to adopt special strategies to monitor this clientele. Comparing the cases of tuberculosis in isolation with the cases of co-infection, no gender-related or age-related differences were observed.
