PREVALÊNCIA AMBULATORIAL EM UM HOSPITAL GERAL DE MARCADORES PARA HEPATITES B E C EM PACIENTES COM INFECÇÃO PELO VÍRUS DA

ABSTRACT - Background - Hepatitis B and C viruses and human immunodefi ciency virus share the same route of transmission, and the prevalence of HBV and HCV infection in patients infected with HIV is greater than it is in the general population. Aim - To determine the prevalence of hepatitis B and C markers in a population of patients with HIV as well as the risk factors involved. Patients and Methods - From 5,870 registration forms of patients with HIV of an Infectology Unit, 587 were randomly selected. From these, the 343 which had investigated the presence of any hepatitis B (HBsAg, anti-HBc or anti-HBs) or C (anti-HCV) marker were retrospectively analyzed. Results - HBsAg was positive in 14/306 (4.6%), anti-HBs was positive in 40/154(26.0%), and anti-HBc in 79/205 (38.5%). The anti-HCV test was reacti ve in 126/330 (38.2%). HBV and HCV co-infection was observed in 7 of the 296 patients who had both HBsAg and anti-HCV tests (2.4%). For those who were HBsAg positive, the main exposure factor was homosexual intercourse (50.0%). For those who were anti-HCV reactive, the main risk factor was intravenous drug use (75.3%). In the HIV mono-infected (185 patients), the most prevalent exposure risk factor was promiscuous heterosexual practices or sexual intercourse with a spouse infected with HIV (83 patients - 44.9%).
