摘要
Background Studies have suggested an association between metabolic-associated fatty liver disease (MAFLD) and intestinal barrier function. The present study aims to investigate the association between MAFLD and intestinal barrier impairment in humans and identify potential risk factors for MAFLD. Methods A total of 491 patients were retrospectively enrolled in this study. The serum levels of diamine oxidase, D-lactate and lipopolysaccharide were measured to evaluate intestinal barrier integrity in patients with and without MAFLD. Binary logistic regression and correlational analyses were conducted to verify the association between MAFLD and serum levels of intestinal barrier biomarkers. Results We enrolled 294 patients with MAFLD and 197 patients without MAFLD in this study. Patients with MAFLD had higher serum levels of diamine oxidase, D-lactate and lipopolysaccharide ( P < 0.001) than those without MAFLD. Multivariate logistic regression analyses showed that BMI [odds ratio (OR) 1.324; P < 0.001], triglycerides (OR 2.649; P = 0.002), nonesterified fatty acids (OR 1.002; P = 0.011), diamine oxidase (OR 1.149; P = 0.011) and D-lactate (OR 1.221; P < 0.001) were independent risk factors for MAFLD. Additionally, serum levels of diamine oxidase and D-lactate increase as liver steatosis became more severe. MAFLD patients with ≥2 metabolic abnormalities had higher serum levels of lipopolysaccharide ( P = 0.034). Conclusions MAFLD is associated with intestinal barrier impairment. Diamine oxidase and D-lactate are potential predictors of MAFLD, and their serum levels are related to liver steatosis. Intestinal barrier impairment is related to metabolic disorders in patients with MAFLD.
