Re-determining the cut-off points of FIB-4 for patients monoinfected with chronic hepatitis B virus infection

Re-determining the cut-off points of FIB-4 for patients monoinfected with chronic hepatitis B... AbstractObjective:This study aimed to determine significant liver fibrosis and cirrhosis with different FIB-4 cut-off points, and the need for liver biopsy (LB) by optimizing the initially established cut-off points of 1.45 and 3.25.Materials and methods:The study included 201 patients monoinfected with chronic HBV. METAVIR classification was used to determine the stage of fibrosis. ROC analysis and the Youden index were performed to define the optimum cut-off points.Results:A FIB-4 cut-off point of 1.45 and 1.62 generated Youden indexes of 0.51 and 0.55, the accuracy of 78.6% and 81.1% for significant liver fibrosis, respectively. The FIB-4 cut-off was set at 2.40 and 3.25 Youden indexes were 0.46 and 0.16, accuracies were 79.6% and 69.7% for significant liver fibrosis, respectively. A cut-off point of 1.45 and 1.62 for FIB-4 generated Youden indexes of 0.62 and 0.66, the accuracies of 81.6% and 84.1% for cirrhosis, while the FIB-4 cut-off point of 2.40 and 3.25 generated Youden indexes of 0.59 and 0.22, with the accuracies of 90% and 84.1% for cirrhosis, respectively.Conclusions:The FIB-4 cut-off points of 1.62 and 2.40 have higher accuracy and may decrease the need for LB 12% more than the initially established ones in HBV monoinfected patients. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Turkish Journal of Biochemistry de Gruyter

Abstract

METAVIR classification was used to determine the stage of fibrosis. ROC analysis and the Youden index were performed to define the optimum cut-off points.Results:A FIB-4 cut-off point of 1.45 and 1.62 generated Youden indexes of 0.51 and 0.55, the accuracy of 78.6% and 81.1% for significant liver fibrosis, respectively. The FIB-4 cut-off was set at 2.40 and 3.25 Youden indexes were 0.46 and 0.16, accuracies were 79.6% and 69.7% for significant liver fibrosis, respectively. A cut-off point of 1.45 and 1.62 for FIB-4 generated Youden indexes of 0.62 and 0.66, the accuracies of 81.6% and 84.1% for cirrhosis, while the FIB-4 cut-off point of 2.40 and 3.25 generated Youden indexes of 0.59 and 0.22, with the accuracies of 90% and 84.1% for cirrhosis, respectively.Conclusions:The FIB-4 cut-off points of 1.62 and 2.40 have higher accuracy and may decrease the need for LB 12% more than the initially established ones in HBV monoinfected patients.
