Abstract

The objective of this study was to evaluate the prevalence of hepatitis B and C viruses in a group of HIV infected patients, followed at a single institution since 1996. 1,693 HIV positive patients (1,162 male, 531 female) were tested for HBV infection. Virological markers for HBV included HBsAg and total anti-HBc by ELISA. 1,457 patients (1,009 male, 448 female) were tested for HCV infection. Detection of HCV antibodies was carried out by ELISA. A sample of HCV antibody positive patients was tested for HCV by PCR to confirm infection. Of 1,693 patients tested for HBV, 654 (38.6%) and 96 (5.7%) were anti-HBc and HBsAg positive, respectively. Of 1,457 patients tested for HCV, 258 (17.7%) were anti-HCV positive. 82 of these patients were also tested by PCR and 81 were positive (98%). Of 1,411 patients tested for HBV and HCV 26 (1.8%) were positive for both viruses.<br>O objetivo do presente trabalho é avaliar a prevalência da infecção causada pelos vírus da hepatite B (HBV) e da hepatite C (HCV) em um grupo de pacientes infectados pelo HIV e acompanhados em uma única instituição desde 1996. 1.693 pacientes infectados pelo HIV (1.162 do sexo masculino e 531 do sexo feminino) foram testados para o HBV. Os marcadores virológicos utilizados para o HBV foram o HBsAg e o anti-HBc total por ELISA. 1.457 pacientes (1009 do sexo masculino e 448 do sexo feminino) foram testados para o HCV. Realizou-se a detecção dos anticorpos para o HCV através da reação de ELISA. Um grupo de pacientes anti-HCV positivos realizou PCR (polimerase chain reaction) para pesquisa do HCV, para confirmação da infecção. Dos 1.693 pacientes testados para HBV, 654 (38,6%) e 96 (5,7%) eram anti-HBc total e HBsAg positivos, respectivamente. Dos 1.457 pacientes testados para HCV, 258 (17,7%) eram anti-HCV positivos. 82 desses pacientes realizaram PCR para HCV e 81 foram positivos (98%). Dos 1.411 pacientes testados para ambos os vírus HBV e HCV 26 (1,8%) foram positivos para ambos os vírus
