Clinic-pathological features of metabolic associated fatty liver disease with hepatitis B virus infection

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: Metabolic associated fatty liver disease (MAFLD) is a novel concept proposed in 2020. AIM: To compare the characteristics of MAFLD and MAFLD with hepatitis B virus (HBV) infection. METHODS: Patients with histopathologically proven MAFLD from a single medical center were included. Patients were divided into MAFLD group (without HBV infection) and HBV-MAFLD group (with HBV infection). Propensity score matching was utilized to balance the baseline characteristics between two groups. In multivariate analysis, HBV infection was associated with significantly lower grade of hepatic steatosis [odds ratio (OR) = 0.088, 95% confidence interval (CI): 0.027-0.291] but higher inflammation level (OR = 4.059, 95%CI: 1.403-11.742) and fibrosis level (OR = 3.016, 95%CI: 1.087-8.370) after adjusting for age, gender, and other metabolic parameters. CONCLUSION: HBV infection is associated with similar metabolic risks, lower steatosis grade, higher inflammation, and fibrosis grade in MAFLD patients.
