AIM:To study the diagnostic value of controlled attenuation parameter(CAP),evaluated by transient elastography,for liver steatosis in patients with chronic hepatitis B(CHB).METHODS:Eighty-eight patients with CHB were enrolled in this study.All of the patients were subjected to transient elastography to determine CAP.These patients also underwent liver biopsy in the same period.Using liver biopsy as a reference,we determined receiver operating characteristic(ROC)curves for different endpoints.Areas under the ROC curves(AUCs)were used to evaluate the diagnostic importance of CAP for liver steatosis in patients with CHB.RESULTS:A positive correlation was observed between the AUCs of CAP and liver pathological stage(r=0.582,P0.05;r=0.068,P>0.05).The mean CAP value at S0 was 209.59±41.25 dB/m,223.84±35.28 dB/m at S1,274.17±43.69 dB/m at S2,and 312.50±25.44dB/m at S3.CAP values among S0,S1,S2,and S3were significantly different(F=17.79,P<0.01).The AUC values for CAP were 0.711(0.592-0.870),0.868(0.748-0.989),and 0.974(0.922-1.026)for S1,S2,and S3,respectively.The optimal cut-off values were219.5,230.0,and 283.5 dB/m.CONCLUSION:CAP is a novel tool that can be used to assess the degree of steatosis.
