Abstract

BACKGROUND AND AIM: There is conflicting evidence regarding the prevalence of and risk factors for metabolic-associated fatty liver disease (MAFLD) in patients with inflammatory bowel disease (IBD). We aimed to determine MAFLD prevalence and risk factors in IBD patients. METHODS: Cross-sectional, case-control study that included all consecutive IBD patients treated at two different university hospitals. Controls were subjects randomly selected from the general population and matched by age, sex, type 2 diabetes (T2D) status and BMI in a 1:2 ratio. MAFLD was confirmed by controlled attenuation parameter (CAP). Liver biopsies were collected when MAFLD with significant liver fibrosis was suspected. Additionally, age- and fibrosis stage-paired non-IBD patients with biopsy-proven MAFLD served as a secondary control group. RESULTS: 831 IBD patients and 1718 controls were included. The prevalence of MAFLD and advanced liver fibrosis (TE = 9.7 kPa) was 42.00% and 9.50%, respectively, in IBD patients and 32.77% and 2.31%, respectively, in the general population (p < 0.001). A diagnosis of IBD was an independent predictor of MAFLD (adjusted OR 1.99; p < 0.001) and an independent risk factor for advanced liver fibrosis (adjusted OR 5.55; p < 0.001). Liver biopsies were obtained from 40 IBD patients; MAFLD was confirmed in all cases and fibrosis of any degree was confirmed in 25/40 (62.5%) cases. BMI and T2D prevalence were significantly lower in IBD-MAFLD patients than in severity-paired patients with biopsy-proven MAFLD. CONCLUSIONS: MAFLD and liver fibrosis are particularly prevalent in IBD patients, regardless of the influence of classic metabolic risk factors.
