title: [The prevalence of HBsAg in hospitalized children as a marker of hepatitis B virus infection].
abstract: The aim of this study was to determine the prevalence of hepatitis B surface antigen (HBsAg) in hospitalised children, as specific marker for hepatitis B virus (HBV) infection. Our study group consists of 517 children, 68 of them diagnosed with chronic hepatitis. For HBsAg determination we used an ELISA test (Labsystems); for some children we also tested by ELISA the following markers: the antibodies and anti-hepatitis C virus (HCV) antibodies. From 517 children 24.28% were HBSAg positive and 75% of children with chronic hepatitis were positive for the same marker. Almost 100% of chronic active hepatitis (CAH) patients was positive for HBSAg.
  
  
  CONCLUSIONS
  1. The prevalence of HBsAg was much higher as compared with the healthy population prevalence; it is a clear prove that HBV infection has an important role in chronic hepatitis appearance. 2. For all HBsAg positive patients, it is necessary to determine other markers like HBeAg-anti-HBe antibodies system as well as markers for other viral hepatitis (HDV, HCV). 3. The anti-HBV infection vaccine will reduce significantly the prevalence of HBV and HDV infections; 4. Biological molecular technique, like PCR will be necessary in our country, in the future, even the price is so high, to monitoring the IFN treatment for chronic infection as unique solution for these patients.
