title: Prevalence of hepatitis C-related cirrhosis in elderly Asian patients infected in childhood.
abstract: OBJECTIVE
  Approximately 20% of hepatitis C virus (HCV) patients develop cirrhosis from infection after about 20 years. The proportion of patients developing cirrhosis for longer than 30 years after infection is unknown. Our objectives were to determine the prevalence of HCV-related cirrhosis in a population of Asian patients who were infected in childhood 20 to 80 years ago and compare this with the prevalence of cirrhosis in Caucasian patients referred to the same hospitals.
  
  
  METHODS
  Retrospective analyses were performed of all patients who had detectable HCV-RNA levels and who attended local hospitals in northeast London between 1992 and 2003. Factors implicated in the development of cirrhosis were examined by multivariable analysis.
  
  
  RESULTS
  A total of 143 adult Asian patients who had been infected with HCV for many decades were compared with 239 Caucasian patients. The prevalence of cirrhosis increased with age. Of Asian patients aged 61-80 years (n = 55) 78% had cirrhosis, whereas 25% of Caucasian patients aged 61-80 years (n = 55) had cirrhosis. Multivariable linear analysis revealed that fibrosis progression and age were similar in both groups and the difference in the prevalence of cirrhosis was not explained by any unique Asian characteristic other than prolonged infection.
  
  
  CONCLUSIONS
  The prevalence of cirrhosis in patients with chronic HCV increases with increasing duration of infection. In Asian patients infected at birth, infection for over 60 years causes cirrhosis in 71% of infected individuals. Because relationship between the severity of fibrosis and age in Asian patients is similar to that seen in Caucasian patients it is likely that similar rates of cirrhosis will be seen in other patients who are infected for more than 60 years.
