Abstract:
Objective To investigate the application of ultrasound and blood indicators in diagnosis of early liver cirrhosis (S4) for patients with chronic hepatitis B (CHB).Methods Data of blood and ultrasound examinations of 631 patients with CHB who received liver biopsy in the Sixth People' s Hospital of Shenyang during April 2002 and March 2011 were collected.Logistic regression analysis was performed to determine the factors independently correlated with early liver cirrhosis,and the diagnostic model was established using these indicators.The diagnostic value of the established model was assessed by using area under receiver operating characteristic curve (AUROC) and compared with FIB-4 index,aspartate aminotransferase (AST)/platelet (PLT) ratio index (APRI) and S index.Results Logistic regression analysis indicated that age,PLT,albumin globulin ratio (A/G) and splenic square area (SPS) in ultrasound findings were independently correlated to early liver cirrhosis (Wald =10056,46.236,3.751 and 10.669,P ＜0.01).AUROC of the model based on the above factors in diagnosing early liver cirrhosis was 0.908,which was higher than those of FIB-1 index,APRI index and S index (Z =8.322,4.334 and 4.087,P ＜ 0.05).Taking 0.063 as cut-off value,the sensitivity,specificity,positive predict value and negative predict value of the established model in diagnosis of early liver cirrhosis were 90.1％,77.8％,50.0％ and 97.1％,respectively.Taking ＜0.060 and ≥0.110 as the cut-off values to exclude,and diagnose early liver cirrhosis,69.7％ (440/631) patients could avoid liver biopsy.Conclusion The model based on age,PLT,A/G and SPS can effectively predict early liver cirrhosis,and can reduce liver biopsy.
