Objetivos: Verificar a prevalência 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, referência para TBC e SIDA. Material e métodos: Todos os pacientes internados com TBC na enfermaria de pneumologia foram avaliados prospectivamente no período de 1/1/1997 até 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 clínicas de TBC. Foram excluídos 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 análise estatística. 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). Não 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 clínicas de TBC. Conclusões: Devido à alta prevalência da infecção pelo HIV (9,2%) no grupo estudado, estes achados reforçam as orientações do Consenso Brasileiro de Tuberculose no sentido de: 1) a anamnese não 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.
Background Cryptococcosis affects more than 220,000 patients/year, with high mortality even when the standard treatment [amphotericin B (AMB), 5-flucytosin (5-FC) and fluconazole] is used. AMB presents high toxicity and 5-FC is not currently available in Brazil. In a pre-clinical study, pioglitazone (PIO - an antidiabetic drug) decreased AMB toxicity and lead to an increased mice survival, reduced morbidity and fungal burden in brain and lungs. The aim of this trial is to evaluate the efficacy and safety of PIO combined with standard antifungal treatment for human cryptococcosis. Methods A phase 1/2, randomized, double blind, placebo-controlled trial will be performed with patients from Belo Horizonte, Brazil. They will be divided into three groups (placebo, PIO 15 mg/day or PIO 45 mg/day) and will receive an additional pill during the induction phase of cryptococcosis’ treatment. Our hypothesis is that treated patients will have increased survival, so the primary outcome will be the mortality rate. Patients will be monitored for survival, side effects, fungal burden and inflammatory mediators in blood and cerebrospinal fluid. The follow up will occur for up 60 days. Conclusions We expect that PIO will be an adequate adjuvant to the standard cryptococcosis’ treatment.
