Abstract:
Objective To investigate the related index of early diagnosis of acute-on-chronic liver failure caused by chronic hepatitis B.Methods 13 cases of the acute-on-chronic liver failure caused by chronic hepatitis B were collected in our department,39 cases of chronic hepatitis B were randomly paired to analyze the difference index.ROC curve analysis was conducted for the different data,then to choose the data whose AUC (area under the curve)is >0.8 to accumulate points,while the cutoff value in the light of Youden index was indentified.Each accu-mulating points data would score 1 point if it is≥cutoff value,otherwise,it would score 0 points.ROC curve analysis was conducted for the total accumulating points,the cutoff value of the total accumulating points according to Youden index was indentified,the sensitivity and specificity were calculated.Results The data of which AUC are >0.8 include glutamic-pyruvic transaminase (ALT)/Upper Limit Of Normal (ULN),neutrophil count (N),alkaline phosphatase (AKP)/ULN,glutamic-oxalacetic transaminease(AST)/ULN,direct bilirubin/total bilirubin(Dbil/Tbil),total bile acid(TBA),whose AUC were respectively 0.869,0.874,0.897,0.917,0.919 and 0.978,while their cutoff value were respectively 18.57,3.1 ×109/L,0.99,22.21,44.41%and 140.20μmol/L.The cutoff value of total accumula-ting points of the six data was 4 points,AUC was 0.987,Youden index was 0.949,and their sensitivity for ealier diag-nosis for the acute -on -chronic liver failure caused by chronic hepatitis B was 100%,specificity was 94.87%. Conclusion The accumulating points of the six data aboved (ALT/ULN,N,AKP/ULN,AST/ULN,Dbil/Tbil,TBA) will help the early diagnosis of acute-on-chronic liver failure caused by chronic hepatitis B.
