Abstract:
Objective To evaluate the value of transient elastography (FibroScan,FS)in predicting hepatic fibrosis in patients with HBeAg-negative chronic hepatitis B (CHB).Methods One hundred and four patients with HBeAg-negative CHB,who were diagnosed and treated in Hubei Hospital of Traditional Chinese Medicine from June 2011 to May 2013,were enrolled in this study.All patients underwent FS for liver stiffness measurement before liver biopsy.Statistical analysis was applied to compare liver stiffness (kPa)with fibrosis stage (de-termined by liver biopsy).The receiver operating characteristic (ROC)curve of FS was constructed,and the area under the ROC curve (AUC)was calculated to analyze the accuracy of live stiffness in predicting significant fibrosis and cirrhosis.Comparison between groups was made by Kruskal-Wallis H test,followed by Mann-Whitney U test for multiple comparisons.The correlation between two variables was an-alyzed by Spearman rank and Pearson correlation test.Results Liver stiffness gradually rose as the degree of hepatic fibrosis increased, with significant differences between groups (P<0.01 or P<0.05).Liver stiffness was positively correlated with the stage of hepatic fibrosis (r=0.810,P<0.01).The AUC of liver stiffness for detecting liver cirrhosis was 0.956;the cut-off value for diagnosing liver cirrhosis was 13.1 kPa;the sensitivity was 92.7%,and the specificity was 80%.Conclusion FS is a promising noninvasive method for the assessment of hepatic fibrosis in patients with HBeAg-negative CHB;particularly,it has high accuracy in the diagnosis of liver cirrhosis.FS combined with direct or indirect markers may play an important role in differential diagnosis and efficacy evaluation in patients with hepatic fibrosis.
