BACKGROUND: Elevated gamma-glutamyl transpeptidase (GGT) is present approximately in half of all patients with non-alcoholic fatty liver disease (NAFLD). NAFLD is the liver manifestation of metabolic syndrome (MS). This study aimed to explore the relationship between GGT and MS or proinflammatory parameters. METHODS: Data from the cross-sectional HepaMeta study conducted in Slovakia in 2011 among Roma living in rural communities were used. Participants (n = 446) were divided into 2 groups; those with elevated GGT and those with normal GGT levels. MS was diagnosed according to the International Diabetes Federation criteria; presence of central obesity and low density lipoproteins (LDL) or high density lipoproteins (HDL), high triglycerides, hypertension, glucose intolerance or type 2 diabetes. Participants were tested for the presence of MS and its components, and biochemical tests for lipid levels (total cholesterol, HDL, LDL, TG) and inflammatory parameters (high sensitivity C-reactive protein--hs-CRP and ferritin) were performed. RESULTS: Of 446 Roma participants, only 29 (6.5%) had GGT levels above the normal value. After exclusion of patients with viral hepatitis and alcohol abuse, patients with elevated GGT suffered from MS more often (p < 0.001), and patients with more MS components had a higher risk of elevated GGT. We found a significant association between GGT and the individual MS components, except HDL (waist circumference > or = 94 cm in men or 80 cm in women: p < 0.01; BMI > 30: p < 0.001; fasting glucose > or = 5.6 mmol/l: p < 0.001; arterial hypertension: p < 0.05, and TAG > or = 1.7 mmol/l: p < 0.001). Patients with elevated GGT levels had also significantly higher hs-CRP (hs-CRP > 2 mg/l: p < 0.001; hs-CRP > 3 mg/l: p < 0.001) and ferritin (ferritin > 300 mg/l: p < 0.01) levels. CONCLUSION: Patients with MS have more significantly elevated levels of GGT. There is a significant association of GGT with individual MS components, except HDL and inflammatory parameters (hs-CRP, ferritin).
