Comparison of FibroTouch and FibroScan for the assessment of fibrosis in chronic hepatitis B patients

Abstract

Objective To explore the diagnostic values of FibroTouch and FibroScan for liver fibrosis in patients with chronic hepatitis B(CHB). Methods This study enrolled patients with CHB who was accepted liver biopsy at Beijing Friendship Hospital, Capital Medical University between March 2014 to December 2017. FibroTouch and FibroScan were performed among these patients at same time. Liver stiffness measurement(LSM), optimal cut-off value, receiver operating characteristic(ROC) were compared. Results In our 103 patients, there were no significantly different between FibroTouch and FibroScan in LSM. The threshold of the optimal cut-off value for FibroTouch and FibroScan were 5.45 versus 5.55 kPa (≥S1), 7.10 versus 6.65 kPa (≥S2), 11.05 versus 9.20 kPa (≥S3), 15.50 versus 15.45 kPa (S4), respectively. The area under the ROC curve for the prediction of the stage1, stage2, stage2, stage 4 of liver fibrosis in these patients were 0.858 versus 0.765 (P=0.54), 0.812 versus 0.801 (P=0.68), 0.863 versus 0.878 (P=0.45), and 1.0 versus 0.99 (P=0.38) respectively. Conclusions FibroTouch and FibmScan have a good consistency in the evaluation of the degree of liver fibrosis in patients with CHB. Key words: Chronic hepatitis B; Fibrosis; FibroTouch; FibroScan
