Abstract
BACKGROUND AND AIMS: We want to investigate whether a novel noninvasive marker is suitable for Chinese CHB patients. METHODS: A total of 160 treatment-naïve CHB patients who underwent liver biopsy were enrolled in our study, and we assessed the diagnostic accuracies of GPR, aspartate transaminase-to-platelet ratio index (APRI), and the fibrosis index based on 4 factors (FIB-4) in them. RESULTS: Of these 160 CHB patients, the numbers of F0, F1, F2, F3, and F4 are 34 (21.3%), 62 (38.8%), 18 (11.3%), 24 (15%), and 22 (13.8%), respectively. The area under the receiver operating characteristic curves (AUROC) of GPR for fibrosis (0.77 versus 0.70, P = 0.03), significant fibrosis (0.70 versus 0.63, P = 0.02), and extensive fibrosis (0.71 versus 0.64, P = 0.02) were significantly higher than those of APRI. The AUROCs of GPR and Fib-4 for fibrosis (0.77 versus 0.75, P = 0.14), significant fibrosis (0.70 versus 0.70, P = 0.22), extensive fibrosis (0.71 versus 0.68, P = 0.13), and cirrhosis (0.64 versus 0.67, P = 0.24) were comparable. CONCLUSIONS: The GPR can be a routine laboratory marker to stage liver fibrosis in patients with CHB in China.
