| Abstract To assess the prevalence of hepatitis C virus infection among men who have sex with men (MSM) in Central Brazil, a cross-sectional study was conducted in the City of Goiânia, Central Brazil, using Respondent-Driven Sampling (RDS). All serum samples were tested for anti-HCV and also for alanine aminotransferase (ALT). Anti-HCV positive samples and/or those with elevated ALT were tested for HCV RNA and genotyped. Of the 522 participants, four were found to be anti-HCV positive, and one was also HCV RNA positive (active HCV infection). Elevated ALT was found in 14 individuals. Of these, one showed evidence of acute HCV infection (HCV RNA positive and anti-HCV negative). Therefore, five MSM were positive for either anti-HCV and/or HCV RNA, giving a... |

| Objectives:A cross-sectional study on prevalence of HBV and HDV infection, risk factors and genotype distribution of HBV infection was conducted among 848 HIV-infected patients in Mato Grosso do Sul, Central Brazil.Methods:Serum samples of 848 participants were tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc) and hepatitis surface antibody (anti-HBs). HBsAg positive samples were tested for anti-HBc IgM, HBeAg, anti-HBe, anti-HCV, and total anti-HDV. HBsAg and anti-HBc positive were subjected to DNA extraction. Viral DNA was amplified by semi-nested PCR for the regions pre-S/S and then purified and genotyped/subgenotyped by direct sequencing. Student's t-test, chi-square test and Fisher's exact test were used to compare... |
