INTRODUCTION: The effects of metabolic syndrome (MetS), its individual components, and baseline liver histology, on the rates of progression and regression of nonalcoholic fatty liver disease (NAFLD), were evaluated.
METHODS: We conducted a post hoc analysis of a multicenter prospective cohort study using the noninterventional registry of the Nonalcoholic Steatohepatitis Clinical Research Network (2002-2022). We included patients aged 18 years or older with biopsy-proven NAFLD. Outcomes included progression/regression of histology defined by changes in NAFLD Activity Score, nonalcoholic steatohepatitis, or fibrosis. Crude incidence rates were compared among patients with MetS vs those without using Kaplan-Meier curves and log-rank test. Cox proportional hazard models were used to estimate effects of MetS and its components on the fibrosis progression/regression.
RESULTS: We included 452 patients; the mean age was 51 years, one-third was male, and 85% was White. The median follow-up was 4.3 (range: 1-15.6) years. At baseline, patients with MetS, large waist circumference, and impaired glucose tolerance/diabetes had worse ballooning and fibrosis scores and a higher prevalence of definite nonalcoholic steatohepatitis than those without. MetS was not associated with fibrosis progression or regression. Impaired glucose tolerance/diabetes was associated with a higher risk of fibrosis progression (adjusted hazard ratio = 1.61; 95% confidence interval: 1.11-2.34) whereas hypertension was associated with a lower risk (adjusted hazard ratio = 0.64; 95% confidence interval: 0.43-0.96).
DISCUSSION: In the cohort of patients with NAFLD, MetS was associated with greater histological severity at baseline but was not a risk factor of disease progression or regression. Impaired glucose/diabetes was associated with a higher rate and hypertension with a lower rate of fibrosis progression.
