Background & aims: With a drastic increase in the number of chronic hepatitis B (CHB) patients with coexisting nonalcoholic fatty liver disease (NAFLD), there is an urgent need to evaluate antiviral treatment effects in this special population. Methods: CHB patients with hepatic steatosis (CHB + HS) were prospectively recruited with followed-up of 3 years. HS and liver fibrosis were assessed by transient elastography. HS was defined as controlled attenuation parameter (CAP) ≥248 dB/m, and fibrosis progression was defined with ≥1-stage fibrosis increment. Multivariate and propensity score matching (PSM) analysis were used to evaluate antiviral therapy effects on fibrosis progression. Results: In total 212 recruited CHB + HS patients (median age 36 years, median ALT 59 U/L), 49.1% (104/212) received antiviral therapy and 50.9% (108/212) did not. Among patients with antiviral therapy, rates of serum HBV DNA undetectable, HBeAg and HBsAg loss, and ALT normalization at year 3 were 88.5%, 31.0%, 8.7% and 70.2%, respectively. Patients with mild-moderate HS didn't differ patients with severe HS regarding biochemical and virological responses. Antiviral therapy was independently associated with a lower risk of fibrosis progression among the entire cohort (odds ratio 0.473, 95% CI 0.245–0.911, P = 0.025). This finding was further verified by PSM analysis. When stratified by the severity of HS, the antiviral therapy benefits in reducing fibrosis progression were mainly seen in patients with mild-moderate HS. Conclusions: Among CHB + HS patients, long-term antiviral treatment effectively inhibits HBV replication and reduces fibrosis progression. Our findings have implications for the optimal management of this population.
