    ObjectiveThe role of Non-Alcoholic Fatty Liver Disease (NAFLD) on antiviral response in Chronic Hepatitis B (CHB) remains unclear. Previous studies mainly focus on the impact of the Non-Alcoholic Fatty Liver (NAFL) on antiviral efficacy, whereas the role of Non-Alcoholic Steatohepatitis (NASH) has not been highlighted. The authors aimed to investigate the association of NAFLD (NAFL and NASH), viral and histological characteristics with antiviral response.MethodsThe authors collected data of treatment-naïve CHB patients who underwent liver biopsy. All these patients received antiviral monotherapy and 48-week follow-up. The antiviral response was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the variables associated with antiviral response.ResultsOverall, 120 treatment-naïve CHB patients were enrolled, with 49.2 % (59/120) of them were complicated by NAFLD. Male (Odd Ratio [OR = 4.222], 95 % Confidence Interval [95 % CI 1.620-11.003]) and overweight (OR = 8.709, 95 % CI 3.355-22.606) were independent predictors for concurrent NAFLD. After 48-week follow-up, the authors found that the overall antiviral response did not differ between CHB patients with and without concomitant NAFL/NASH (p > 0.05). High viral load (Hazard Ratio [HR = 0.522], 95 % CI 0.286-0.952), advanced fibrosis (HR = 2.426, 95 % CI 1.256-4.686), and moderate-to-severe interface hepatitis (HR = 2.541, 95 % CI 1.406-4.592) were significantly correlated with antiviral response after 8-week follow-up.ConclusionNeither NAFL nor NASH had an impact on antiviral therapy for CHB. It was low hepatitis B load, advanced fibrosis, and moderate-to-severe interface hepatitis that contributed to the virological response.Copyright © 2024 HCFMUSP. Published by Elsevier España, S.L.U.
