Abstract
Viral hepatitis is a global health problem. Uptill now five I, es of VH have been categorized; namely VHA, VHB, VHC, VHD, d VHE. Of these VHB is considered to be more serious due to the 11 ,her incidence of dismal sequelae in patients with IiBV infection an other types. The prevalence of VIiB is quite different all over the world, ing lowest in the Scandinavian countries, USA &. Canada; modest in the Mediterranean basin; and highest in most of the tropical &. btropical countries. In Egypt it is moderately endemic with a carrier rate of 4-6. Fortunately most cases (90.) of acute VIiB resolve jl ontaneously within 3-6 months. Only 1-10 of cases proceed to :omplications. The World liealth Organization estimated that :1: round 300,00,000 individuals worldwide are chronically infected ”’ith HBV of whom 20-25 die annually from the chronic sequelae. 11 The risk of development of chronic IiBV infection depends pon many factors mainly the age that is inversely related to it; the sex which shows male predominance; the immunological status; as w~1I as the genetic element. This study was designed to: I, investigate the impact of the demographic characteristics and the associated diseases on the outcome of HBV infection. il. assess the prognostic value of the liver function tests and HBV markers in predicting HBV infection outcome.
