Hepatitis A virus infection in high-risk subjects

Original abstract: Background & Aims. Several outbreaks of hepatitis A affecting homosexual men have been reported in Europe. However, the prevalence of HIV infection in patients affected by hepatitis A has not been extensively studied and hepatitis A is not considered as an indicator disease for routine HIV testing.Methods. We retrospectively analyzed all adult cases of acute hepatitis A, reported by the National Institute of Infectious Disease “L. Spallanzani”, Rome-Italy, in 2002-2008. Data on HIV infection were obtained by chart review and cross-linkage with laboratory. Information on exposure to risk factors were collected from the standard questionnaire of the Local Health Unit.Results. We analyzed a total of 473 cases of hepatitis A, 368 (77.2%) males that accounted for 75% of all reported cases in Rome, aged 25-64 years (same gender distribution). During the study period, we diagnosed a high proportion of cases among male individuals (78%). Among the male patients, HIV serology was available for 203/368 (55.2%). The overall HIV prevalence was 15.2% (56/368); it was significantly associated with same gender sex and was significantly higher than that observed among patients with hepatitis B (4.0%).Conclusions. We found a high HIV prevalence, associated with same gender sex, among adult male patients diagnosed with hepatitis A in the period 2002-2008, except for 2006. Our data suggest that in a low incidence area for hepatitis A, with a constant high proportion of cases among male individuals, all individuals with acute hepatitis A should be routinely offered an HIV test

Association Between Serum Hemoglobin Levels and Non Alcoholic Fatty Liver Disease in a Mexican Population

Introduction and aim. Nonalcoholic fatty liver disease (NAFLD) is closely associated with overweight and obesity, becoming one of the most prevalent hepatic diseases nowadays. Circulating hemoglobin (Hb) concentration is significantly higher in people with NAFLD, compared to healthy patients. While liver biopsy remains the gold standard for NAFLD diagnosis, it is not the best technique due to adverse events that may occur. Therefore it is important to find less invasive and more sensitive markers. This study aimed to determine the association of serum Hb levels in patients with steatosis and fibrosis as a noninvasive marker.Material and methods. A 1,186 patient cross-sectional study nested in a randomized clinical trial (NCT01874249) was conducted. Patients were diagnosed by ultrasound for hepatic steatosis and fibroscan for fibrosis; blood test and anthropometric measurements were also assessed.Results. Serum Hb increased proportionally related to the steatosis level, being significantly higher in patients with severe steatosis than in patients with moderate and mild steatosis.Conclusion. Patients with non-alcoholic fatty liver disease showed elevated levels of circulating Hb, evidence that suggests that Hb exerts a protective role, as it may act as an antioxidant and may counteract the adverse effects of this disease
