Abstract The prevalence of infection with hepatitis B virus in Portugal is around 1% of the population; 20-30% of those infected typically develop cirrhosis. The study focuses on the epidemiological profile of patients with hepatitis B infection and liver damage, in particular, cirrhosis. Of the 358 individuals that comprised the study, a liver biopsy was performed in 249 to identify the presence of cirrhosis. Cirrhosis was observed in 59 patients (23.7%) The Child-Pugh classification was used to assess the prognosis of cirrhosis: 3 out of the 59 patients were classified as Child-Pugh grade C, the most severe, 17 (28.8%) as grade B, and 39 (66.2%) as grade A. Patients classified as grade B were older, drank more, and showed higher levels of AST and alkaline phosphatase when compared with individuals classified as grade A. Genotypes A and D were predominant, and no significant differences with respect to genotype distribution were observed. Analysis of the hematological parameters showed that patients classified as Child's grade B had lower levels of platelets and higher levels of prothrombin time than those classified as Child's grade A. The profile of the patients with cirrhosis, including an extended number of individual characteristics, provides useful information, however, only a prospective study could evaluate definitively if liver disease is influenced by these factors. Future studies would benefit from the analysis of the impact of genotypes on liver disease, particularly genotypes A and D, the most predominant genotypes in northern Portugal. © 2010 Wiley-Liss, Inc.
