The analysis of the genomes of the hepatitis B virus in human hosts identifies phylogenetic variants called viral genotypes. Indeed, clinical and epidemiological observations suggest that differences in viral genotypes lead to distinct biological and clinical behaviors. The aim of this study was to evaluate the subgenotypic distribution and to conduct a(More)
BACKGROUND A correlation between the levels of serum globulins and the hepatic fibrosis degree in chronic hepatitis was described, but reports in schistosomiasis mansoni have not been found. OBJECTIVE To evaluate the serum globulins and IgG levels, and periportal fibrosis intensity measured by ultrasound in patients with schistosomiasis mansoni. METHODS(More)
The patients with chronic renal failure in hemodialysis present low levels of serum alanine aminotransferases. In order to establish a better cutoff value for ALT in hepatitis C screening of hemodialysis patients, the ALT levels were measured monthly in 235 patients, being excluded those that presented average above the upper limit of normality. The cutoff(More)
Hepatitis C virus (HCV) is a public health problem throughout the world and 3% of the world population is infected with this virus. It is estimated that 3-4 millions individuals are being infected every year. It has been estimated that around 1.5% of Brazilian population is anti-HCV positive and the Northeast region showed the highest prevalence in Brazil.(More)
The evidence of a higher incidence of hepatitis G virus (HGV) infection among patients with hepatocellular carcinoma (HCC) and the relatively high prevalence of patients with primary liver carcinoma without apparent risk factors in our country motivated the present study, the objective of which was to determine the frequency of HGV-ribonucleic acid (RNA) in(More)
BACKGROUND The epidemiology of Helicobacter pylori (Hp) still constitutes a relevant subject of investigation. GOAL The goal of this study was to determine the seroprevalence rate of Hp antibodies in medical students and residents, and its relationship with medical practice, age, gender and parents' formal education level. STUDY The study was carried(More)
