Clinical and epidemiological profile and prevalence of tuberculosis/HIV co-infection in a regional health district in the state of Maranhão, Brazil.

OBJECTIVE To describe the clinical and epidemiological profile, as well as the prevalence, of tuberculosis/HIV co-infection in the Regional Health District of Tocantins, which serves 14 cities in the state of Maranhão, Brazil. METHODS This was a descriptive epidemiological study based on secondary data obtained from individual tuberculosis reporting forms in the Brazilian Case Registry Database. We included all reported cases of tuberculosis/HIV co-infection, by city, between January of 2001 and December of 2010. RESULTS In the district, 1,746 cases of tuberculosis were reported. Of those tested for HIV, 100 had positive results, which corresponded to a tuberculosis/HIV co-infection prevalence of 39%. Of the co-infected patients, 79% were male, 42% were Mulatto, and 64% were in the 20- to 40-year age bracket, 31% had had < 4 years of schooling, and 88% resided in the city of Imperatriz. Cases of pulmonary tuberculosis and new cases of tuberculosis predominated (in 87% and 73%, respectively). Of the co-infected patients, 27% had positive sputum smear microscopy results, and 89% had chest X-ray findings suggestive of tuberculosis. Sputum culture was performed in only 7% of the cases. CONCLUSIONS Our results show that, because of its clinical and epidemiological profile, tuberculosis/HIV co-infection is still a major public health problem in the southwestern region of Maranhão. This situation calls for better coordination between tuberculosis and sexually transmitted disease/AIDS control programs, as well as a political commitment and greater involvement on the part of administrators and health care professionals in the planning of interventions and the functioning of health care facilities.
