    Objetivos: Verificar a prevalĂȘncia da co-infecção tuberculose (TBC)/HIV e a capacidade da anamnese em detectar a infecção pelo HIV em pacientes internados por TBC. Local: Hospital Eduardo de Menezes, Belo Horizonte, MG, referĂȘncia para TBC e SIDA. Material e mĂ©todos: Todos os pacientes internados com TBC na enfermaria de pneumologia foram avaliados prospectivamente no perĂ­odo de 1/1/1997 atĂ© 31/1/1998, com anamnese dirigida para fatores de risco para SIDA, TBC, tratamentos anteriores e abandonos de tratamento para TBC, e verificadas as formas clĂ­nicas de TBC. Foram excluĂ­dos pacientes com doenças marcadoras de SIDA com exceção da TBC, ou com sorologia anti-HIV realizada anteriormente. Foram realizadas sorologias anti-HIV (ELISA) e, quando positivas, confirmadas pelo teste Western-Blot. Os testes do qui-quadrado e de Fisher foram usados para anĂĄlise estatĂ­stica. Resultados: Sessenta e cinco pacientes avaliados foram divididos em grupo I (sorologia positiva para HIV, n = 6) e grupo II (sorologia negativa para HIV, n = 59). NĂŁo houve diferença significativa entre os dois grupos quanto a fatores de risco para SIDA, TBC, abandonos de tratamento ou tratamentos anteriores para TBC ou formas clĂ­nicas de TBC. ConclusĂ”es: Devido Ă  alta prevalĂȘncia da infecção pelo HIV (9,2%) no grupo estudado, estes achados reforçam as orientaçÔes do Consenso Brasileiro de Tuberculose no sentido de: 1) a anamnese nĂŁo consegue detectar uma parcela significativa dos pacientes com co-infecção TBC/HIV; e: 2) a solicitação de sorologia anti-HIV deve ser feita de forma rotineira em todos os pacientes com TBC ativa.<br>Objectives: To verify the prevalence of tuberculosis (TB)/HIV co-infection and the ability of the clinical history to detect the HIV infection in TB inpatients. Setting: Eduardo de Menezes Hospital, reference for both TB and AIDS. Patients and methods: All patients admitted with TB in a pneumology ward were evaluated prospectively from 1/1/1997 to 1/31/1998. The clinical history was directed to the presence of risk factors for AIDS or TB, previous treatments or abandoned treatments for TB, and TB clinical forms. Patients with AIDS defining illnesses, except for TB, and with previous anti-HIV tests were excluded. All patients had an ELISA anti-HIV serology, and when positive, a Western-Blot test was performed to confirm the previous result. X-square test and Fisher test were used for statistical analysis. Results: Sixty-five patients were divided into group I (positive serology for HIV, n = 6) and group II (negative serology for HIV, n = 59). There were no statistical differences between the groups comparing the risk factors for AIDS and TB, previous treatments or abandoned treatments for TB, or TB clinical forms. Conclusions: The high prevalence of TB/HIV co-infection (9.2%) reinforces that: 1) the clinical history was not able to detect a significant number of patients with TB/HIV co-infection and that: 2) anti-HIV serology should be performed in all patients with active TB forms
