title: Clinical significance of portal lymphoid aggregates/follicles in Chinese patients with chronic hepatitis C.
abstract: OBJECTIVE
  Portal lymphoid aggregates/follicles (lymphoid A/F) is a characteristically histological finding in patients with chronic hepatitis C. We assessed the prevalence of lymphoid A/F in Chinese patients with chronic hepatitis C and evaluated the correlation of this phenomenon with clinical, biochemical, immunological, virological, and other histological features of these patients.
  
  
  METHODS
  Eighty-nine Chinese patients with chronic hepatitis C were enrolled and portal lymphoid A/F was evaluated in liver biopsy. Clinical, biochemical, immunological, histological, and virological data, including serum HCV RNA titer and HCV genotype and the response to interferon therapy, were compared between patients with and without portal lymphoid A/F.
  
  
  RESULTS
  Twenty-nine (33%) of 89 patients with chronic hepatitis C had portal lymphoid A/F. Patients with lymphoid A/F had a significantly higher frequency of HCV genotype 1b infection (p = 0.039) and had a significantly higher mean score of bile duct damage, periportal necroinflammation, and portal inflammation in liver histologies when compared with patients without lymphoid A/F. No significant difference in sex distribution, mean age, history of blood transfusion, serum liver biochemistry, presence of serum autoantibodies/cryoglobulinemia, serum viral titer, and response to interferon therapy was noted between the two groups. Multivariate logistic regression analysis showed HCV genotype 1b infection and periportal necroinflammation were significant independent predictors associated with portal lymphoid A/F.
  
  
  CONCLUSIONS
  The presence of portal lymphoid A/F in Chinese patients with chronic hepatitis C was significantly correlated with HCV genotype 1b infection and periportal necroinflammation.
