title: Persistent infection of hepatitis C virus in the elderly: a clinical and quantitative pathological study of autopsy cases.
abstract: OBJECTIVE
  The entire spectrum of persistent infection by hepatitis C virus (HCV) is still unknown.
  
  
  METHODS
  A total of 37 autopsy cases, positive with second generation anti-HCV ELISA, were analyzed. The cases comprised 15 males and 22 females, the average ages being 76.5 in males and 81.1 in females. Twenty-one cases were found to be asymptomatic, while 16 were symptomatic.
  
  
  RESULTS
  Based on two pathological parameters of hepatic fibrosis and inflammation, the cases were divided into five groups; group A (non-inflammatory group without significant fibrosis; 11 cases), group B (inflammatory group without significant fibrosis; 9 cases), group C (non-inflammatory group with significant fibrosis; 1 case), group D (inflammatory group with significant fibrosis; 11 cases) and group E (undetermined inflammatory index; 5 cases). All cases in group A and seven cases in group B were asymptomatic. Group A included 6 cases with normal liver. All cases in groups C and D were symptomatic. All examined cases of the inflammatory groups were positive for serum HCV-RNA.
  
  
  CONCLUSIONS
  Anti-HCV-positive elderly autopsy patients include many asymptomatic cases. The two pathological parameters of hepatic fibrosis and inflammation can be used to divide the cases into five groups with each group being well correlated with clinical and virological features.
