摘要: 目的探讨10种无创诊断肝纤维化指数对慢性乙型肝炎患者肝纤维化诊断的准确性。方法回顾性分析2008年1月~2014年12月期间行肝穿刺活检术诊断的1362例CHB患者的临床资料,分别计算不同的指数得分。以受试者工作特征曲线下面积(AUROC)评价各指数的准确性,采用DeLong法对各指数诊断的准确性进行比较。结果本组资料显示,诊断显著肝纤维化(≥S2)的AUROC依次为:S指数(0.745)、GPRI (0.736)和APRI (0.681);诊断肝硬化(S4)的AUROC依次为:S指数(0.716)、FIB-4(0.708)和GPRI (0.707);S指数诊断肝硬化时,其截断点为0.03,敏感度为98.8%,阴性预测值为97.0%,阴性似然比为0.14;截断点为1.5的特异度为99.5%,阳性预测值为70.0%,阳性似然比为10.1;S指数诊断显著肝纤维化时,其截断点为0.89,特异度为99.5%,阳性预测值为98.5%,阳性似然比为11.5;截断点为0.02的敏感度为97.7%,阴性预测值为40.0%,阴性似然比为0.26。结论在10个无创诊断指数中,S指数的诊断性能相对最佳,值得进一步研究。

Abstract: Objective To evaluate the diagnostic efficacy of ten noninvasive indexes for liver fibrosis in patients with chronic hepatitis B. Methods The data of 1362 patients with chronic hepatitis B between January 2008 and December 2014 were collected and statistically analyzed. Results For significant fibrosis diagnosis,the best AUROCs of S index,GPRI and APRI were 0.745,0.736 and 0.681,respectively;For cirrhosis diagnosis,the best AUROCs were S index(0.716),FIB-4 (0.708) and GPRI 0.707,respectively;In diagnosing liver cirrhosis,the cut-off value of S index was 0.03,with a sensitivity of 98.8%,a negative predictive value of 97.0% and a negative likelihood ratio of 0.14;and the cut-off value 1.5 showed a specificity of 99.5%,a positive predictive value of 70.0% and a positive likelihood ratio of 10.1;For significant fibrosis diagnosis,the cut-off value of S index was 0.89,with a specificity of 99.5%,a positive predictive value of 98.5% and a positive likelihood ratio of 11.5;the cut-off value 0.02 showed a sensitivity of 97.7%,a negative predictive value of 40.0% and a negative likelihood ratio of 0.26. Conclusions S index has a relatively good accuracy and is superior to other nine noninvasive diagnostic indexes in diagnosing significant liver fibrosis in patients with chronic hepatitis B.
