Summary:The age of persons with hepatitis A virus (HAV) infection in the general population has risen; these persons are at increased risk of clinically severe disease, especially patients with chronic liver disease. The aim of the present study was to analyze the prevalence of total antibodies against HAV in patients with chronic liver disease. In a prospective study carried out between September 1998 and June 1999, 180 patients seen in the chronic liver disease outpatient department were studied. The prevalence of total anti-HAV antibodies was determined by age group, etiology and degree of histological damage, and according to the antecedents of risk for parenteral infection. A nonconditional logistic regression model was fitted with anti-HAV positivity as the dependent variable. Mean age was 44.1 years, with an anti-HAV prevalence of 77.2% (varying from 42.9% in the 21-25-year-old group to more than 83% in patients > 56-years old). Differences across groups regarding other categories (histological damage, etiology and history of parenteral or drug use) were not statistically significant, but the probability of anti-HAV positivity increased with age and a history of drug addiction. The prevalence of total anti-HAV antibodies is high among patients with chronic liver disease. We therefore recommend this test before vaccination against HAV, until current recommendations on universal childhood vaccination are implemented, in order to prevent hepatitis A epidemics in the general population.
