Background & Aims: Chronic hepatitis B (CHB) can cause liver fibrosis and lead to cirrhosis even cancer, antiviral therapy can reverse liver fibrosis with limited effect, thus we aimed to evaluate the effect of An-Luo-Hua-Xian pill (ALHX) on fibrosis regression in CHB patients treated with ETV.Methods: Treatment naïve patients with CHB from Oct 1st, 2013 to Dec 31st, 2020 were randomly treated with ETV alone or combined with ALHX (ETV+ALHX). Patients’ demographic, laboratory and liver histology data before and after 78 weeks of treatment were collected. Ishak fibrosis score (F) was used and fibrosis regression means F decreased ≥1 after treatment.Results: In total, 394 patients with a second liver biopsy after treatment were included in per-protocol population: 132 patients in ETV group and 262 patients in ETV+ALHX group. After 78 weeks of treatment, the fibrosis regression rate in the ETV+ALHX group were significantly higher than ETV group in baseline F≥3 patients: 124/211 (58.8%) verse 45/98 (45.9%), p=0.035. The degradation rate of liver stiffness measurement (LSM) is also consistent with it: 154/262 (73.0%) in ETV+ALHX group and 60/132 (61.2%) in ETV group, p=0.037. Logistic regression analysis showed that combined with ALHX was related to fibrosis regression (OR=1.94, p=0.018), and family history of hepatocellular carcinoma was on the contrary (OR=0.41, p=0.031).Conclusions: ETV combined with ALHX can significantly increase liver fibrosis regression in CHB patients.
