Liver histology was evaluated by the METAVIR scoring system. Receiver operator characteristic curves were applied to the diagnostic value of CP for measuring liver fibrosis in CHB patients. Spearman rank correlation analyzed the relationship between CP and liver fibrosis. A noninvasive model was set up through multivariate logistic regression analysis.RESULTS Serum CP levels individualized various fibrosis stages via area under the curve(AUC) values. Multivariate analysis revealed that CP levels were significantlyrelated to liver cirrhosis. Combining CP with serum GGT levels, a CG model was set up to predict significant fibrosis and liver cirrhosis in CHB patients with normal or minimally raised ALT. The AUC, sensitivity, specificity, positive predictive value, and negative predictive value were 0.84, 83.1%, 78.6%, 39.6%, and 96.5% to predict liver cirrhosis, and 0.789, 80.26%, 68.38%, 62.25%, and 84.21% to predict significant fibrosis. This model expressed a higher AUC than FIB-4(age, ALT, aspartate aminotransferase, platelets) and GP(globulin, platelets) models to predict significant fibrosis(P = 0.019 and 0.022 respectively) and revealed a dramatically greater AUC than FIB-4(P = 0.033) to predict liver cirrhosis.CONCLUSION The present study showed that CP was independently and negatively associated with liver fibrosis. Furthermore, we developed a novel promising model(CG), based on routine serum markers, for predicting liver fibrosis in CHB patients with normal or minimally raised ALT.展开更多
