Introduction:
Non-invasive tests (NITs) have been alternative methods of liver biopsy for the cross-sectional assessment of liver fibrosis in patients with chronic hepatitis B (CHB). However, there are limited data on the longitudinal association between NITs and histological changes of liver fibrosis. This study aimed to evaluate whether NITs can be used to assess liver fibrosis regression (LFR) during anti-HBV treatment.
Methods:
This retrospective study included 337 patients with CHB who underwent contemporaneous NITs, such as liver stiffness measurement (LSM), the aspartate aminotransferase to platelet ratio index (APRI), the fibrosis index based on four factors (FIB-4), and the γ-glutamyl transpeptidase to platelet ratio (GPR), and liver biopsy at baseline and followed by a repeated liver biopsy and NITs assessment. The LFR was defined as fibrosis regression by at least one stage assessed by METAVIR scoring system.
Results:
The median interval between the two paired liver biopsy assessment was 31 months (IQR 24-45). At the first liver biopsy, the fibrosis stage was F2 in 159 (47.2%), F3 in 68 (20.2%), and F4 in 110 (32.6%) patients. At the second liver biopsy, the number of patients with fibrosis stages F0-1, F2, F3, and F4 was 102 (30.3%), 106 (31.5%), 63 (18.7%), and 66 (19.6%), respectively. At follow-up liver biopsy, 169 patients (50.1%) had LFR, 128 patients (38.0%) had no change in fibrosis stage, and 40 patients (11.9%) had liver fibrosis progression on histology. A decrease in liver stiffness measurement (LSM) by 25% is the optimal cutoff for predicting LFR. Patients with a 25% or larger decrease in LSM value had more LFR than those with a less than 25% decrease in LSM value (78.1% vs 22.9%, p < 0.001).
Conclusion:
LSM might be used to monitor regression of liver fibrosis during antiviral treatment using nucleos(t)ide analogues (NUCs) in patients with CHB.
