Routine indexes for cirrhosis and significant fibrosis detection in patients with compensated chronic hepatitis B

Abstract Background and aim Fibrosis index based on the four factors (FIB-4) and aspartate aminotransferase to platelet ratio index (APRI) were not well validated in patients with chronic hepatitis B (CHB). The aim of this study was to validate the performances of these indexes and construct novel indexes for liver fibrosis assessment. Methods A total of 1438 consecutive antivirus treatment-naive patients with CHB were analysed, and two novel indexes (named HeBCI and HeBFI) were derived for cirrhosis and significant fibrosis detection. Results For cirrhosis, the area under receiver operating characteristic curves (AUROCs) were 0.841 for HeBCI, 0.708 for FIB-4 and 0.623 for APRI in the model set, and 0.779, 0.690, 0.595 in the validation set. For significant fibrosis, the AUROCs were 0.781 for HeBFI, 0.693 for APRI and 0.641 for FIB-4 in the model set, and 0.776, 0.729, 0.641 in the validation set. HeBCI determined 750 (52.2%) patients as having cirrhosis or non-cirrhosis with an accuracy of 86%. HeBFI detected 673 (46.8%) patients with or without significant fibrosis with an accuracy of 76.6%. Conclusions As economical and convenient indexes, HeBCI and HeBFI are suitable to serve as outpatient tools for detecting significant fibrosis and cirrhosis to reduce the need of liver biopsy significantly in resource-limited settings.
