| Bacterial infections are important factors in decompensation, and they increase the mortality rate of patients with liver cirrhosis. The most common infections among these patients are spontaneous bacterial peritonitis, pneumonia, skin infections and urinary tract infections (UTI). This transversal study evaluated the frequency of UTI in non-hospitalized patients with cirrhosis followed in a hepatology outpatient unit. Patients with clinical, laboratorial, echographic and/or histological diagnosis of cirrhosis were evaluated from April 2002 to August 2004. Patients who accepted participating in this study were submitted to clinical evaluation and the following laboratorial examinations: urine analysis, urine culture, blood culture and hepatic function... |

| A sentinel study on viral hepatitis is currently being carried out in the village of Cavunge in a semiarid rural region of the state of Bahia, northeastern Brazil. This study has identified individuals in whom anti-HBc IgG was the only serological marker for hepatitis B virus (HBV). This serological pattern may constitute evidence of occult HBV infection. This study Investigated the possibility of occult hepatitis B virus infection in individuals in a rural community who tested positive for anti-HBc IgG alone. A cross-sectional population-based study. ELISA III was performed on serum samples to test for serological viral markers, and ultrasensitive PCR (US-PCR) was used to assess viremia. Among the 1,536 serum samples, 3.6% (n=55) were positive for... |

| In the village of Cavunge, located in a dry tropical, semiarid rural region of the state of Bahia, Brazil, a sentinel study on viral hepatitis is underway. We report on the first part of the study. The objective of this study was to determine the prevalence of serological markers for hepatitis A, B and C in the village. Cross sectional study. Blood samples were tested for serological markers of hepatitis A (HAV), B (HBV) and C (HCV) through ELISA-III assay. In HBsAg and anti-HCV carriers, HCV-RNA and HBV-DNA were checked by PCR. The prevalence of anti-HAV IgG was 83.3% (1,210/1,452), being higher among residents from the village (87.4%) than in residents from the rural area (79.5%); it also higher among individuals older than 10 years of age.
