Clinical and pathological features of primary biliary cirrhosis / 中华风湿病学杂志

ABSTRACT

Objective The aim of this study was to describe the clinical and pathological features of primary biliary cirrhosis(PBC) and their correlation.Methods Liver biopsy specimens were obtained through percutaneous needle puncture from twenty four patients with PBC who had not been diagnosed or treated before.These samples were fixed in formaldehyde and embedded in paraffin for routine histological examination.Pathologic stages based on Ludwig criteria,fibrosis,portal and periportal inflammation,lymphocytic periportal piecemeal necrosis,ductular proliferation,intralobular hepatocyte necrosis,the degree of ductopenia and relevant laboratory results were recorded.Statistics method used was x2 or t-test,Mann-whitmey U nonperametric test and Pearson's or Spearman's correlation analysis.Results The pathological stages,degree of fibrosis were positively correlated with total bilirubin (TBIL) level,total bile acid (TBA),cholesterol (CHO),IgG levels,and were negatively correlated with serum albumin(ALB) level(r=-0.527,P=0.030; r=-0.503,P=0.039) ,percentage of eosinophilic cells (EOS) ( r=-0.554,P=0.021; r=-0.502,P=0.040).Lymphocytic periportal piecemeal necrosis was positively correlated with alkaline phosp-hatase (ALP),TBIL,DBIL,TBA,and also tumor necrosis factor-αt (TNF-αα) levels(r=0.617,P=0.006).Conclusion TBIL,DBIL,TBA,CHO,IgG and ALB,EOS are good surrogate markers for disease sever ity and reversibility of PBC,while ALP,TNF-Cα,TBIL,DBlL,TBA can be used as markers for disease activity.
