CIRION MARTINEZ, Gladys Rafaela et al. Histological diagnosis of chronic viral hepatitis B. Rev Ciencias Médicas [online]. 2010, vol.14, n.4, pp.3-16. ISSN 1561-3194.

Nowadays 350 millions of people suffer from chronic hepatitis B all over the world; this is a frequent cause of chronic hepatitis, hepatic cirrhosis and hepatocellular carcinoma. Objective: to characterize the histopathological alterations of chronic hepatitis B at "Abel Santamaria Cuadrado" University Hospital from January 2002 to December 2009. Design: biopsies having the diagnosis of chronic viral hepatitis by means of a retrospective and cross-sectional design were analyzed. Method: the target group included 259 biopsies with the diagnosis of chronic viral hepatitis and the sample contained 126 biopsies with the diagnosis of chronic hepatitis B. Age, sex, histological lesion and in correspondence with the diagnosis between the histological degree of the lesion and fibrosis stage according to the age. Descriptive statistics was used to sum up categorical and quantitative variables as well as calculations to confirm frequencies and/or associations of variables X2 and odds ratio (OR). Results: representative histological draws for the classification of chronic viral hepatitis were created (Ishak, 1995). Chronic hepatitis B was mainly diagnosed in men (35-44 years old) during the period studied. In all the parameters analyzed of necrosis and inflammation, that one of the point 1 was the most frequent, minimal necrotic-inflammatory activity reached 34, 9%. Mild fibrosis was highly observed. Conclusions: it was confirmed that the system of draws makes possible a better standardization of the diagnosis in a group. Chronic hepatitis B was more frequent between 35-44 years old, prevailing minimal necrotic-inflammatory activity and mild fibrosis.
