title: [The role of the hepatitis B, C and D viruses in the etiology of chronic hepatopathies in Cluj].
abstract: OBJECTIVE
  We studied the prevalence of viral hepatitis B, C and D markers in chronic hepatopathies from Cluj.
  
  
  METHODS
  Sera of 297 patients with chronic hepatopathies (236 adults and 61 children) have been tested for viral hepatitis markers: HBsAg, anti-HBc, anti-HBs, HBeAg, anti-HBe, anti-HDV, anti-HCV, by automated ELISA.
  
  
  RESULTS
  HBV infection markers in 32% (adults) and 4.9% (children), and HDV infection markers in 11.8% (adults) and 26.3% (children). Double (HBV and HCV) and triple infection (HBV, HDV and HCV) were observed in 28.4% (adults), 4.9% (children), and 3.4% (adults), 0% (children), respectively.
  
  
  CONCLUSIONS
  Hepatitis virus infection markers, especially HBV and HCV play an important role in the determinism of chronic hepatopathies from Cluj area, both in children and adults.
