Özet
Background: Metabolic syndrome (MetS) comprises interrelated metabolic abnormalities that collectively confer increased risk of cardiovascular disease and hepatic morbidity. The MAF-5 score is a non-invasive prognostic marker of liver fibrosis and mortality, while Cystatin C (CysC) is a sensitive indicator of renal function that also reflects inflammation, atherosclerosis, and metabolic dysfunction. Although both MetS and CysC have been widely studied, their potential interplay via MAF-5 remains unclear. We aimed to investigate the relationship between MAF-5 scores and CysC levels in MetS patients for the first time. Materials and Methods: Adults (≥18 years) with MetS were included in this study. MAF-5 scores (based on waist circumference, BMI, diabetes status, AST, and platelet count) and CysC levels were recorded. The MAF-5–CysC relationship was assessed via Pearson correlation. Participants were grouped into MAF-5 quartiles, and continuous variables were compared using ANOVA with Bonferroni-corrected pairwise tests. Results: We included 347 MetS patients (54.8% female, median age 54 years). The median MAF-5 score was 1.25, and MAF-5 correlated positively with CysC (r = 0.357, p < 0.001). CysC levels differed significantly across MAF-5 quartiles (Q1 = 0.96, Q2 = 0.99, Q3 = 1.06, Q4 = 1.09; p < 0.001), with Q4 showing higher values than Q1 and Q2. Conclusions: A significant correlation was found between MAF-5 scores and CysC in patients with MetS. CysC levels differed significantly across MAF-5 quartiles, suggesting a potential link between systemic inflammation, liver fibrosis, and CysC. These results highlight shared inflammatory and fibrotic pathways, underlying metabolic dysfunction. Clinically, combined assessment of MAF-5 and CysC may improve risk stratification, identifying patients at higher risk for hepatic fibrosis and adverse outcomes.
