Abstract:
BACKGROUND/AIMS: Serum fibroblast growth factor-21 (FGF-21) levels are elevated in obesity, metabolic syndrome, and type 2 diabetes. Clinical studies have demonstrated an association between FGF-21 and nonalcoholic fatty liver (NAFL) in the general population. This study investigated the association between FGF-21 and NAFL in Korean men with type 2 diabetes. METHODS: Clinical and biochemical metabolic parameters were measured in 135 Korean men with type 2 diabetes (mean age: 56.2 +/- 9.2 years; HbA1C: 7.6 +/- 1.5%). Serum FGF-21 was determined by enzyme-linked immunosorbent assay. NAFL severity was assessed by ultrasound of the liver. High-grade (hg) NAFL was defined as moderate or severe fatty liver. RESULTS: The patients were divided into three subgroups according to NAFL severity: normal (17.0%), low-grade (50.4%), and high-grade (32.6%). Patients with hgNAFL had a larger waist circumference and higher body mass index (BMI), homeostatic model assessment-estimated insulin resistance (HOMA-IR) score, and triglyceride (TG), liver enzyme, and FGF-21 levels than those with a normal liver. FGF-21 correlated positively with BMI, serum creatinine (Cr), TG, liver enzymes, and high-sensitivity C-reactive protein, but negatively with high density lipoprotein (HDL). In multivariate regression analysis, Cr and TG were independently associated with FGF-21. BMI, TG, HDL, HOMA-IR, and FGF-21 correlated strongly with hgNAFL. The odds ratio (OR) of a 1-standard-deviation increase in FGF-21 predicting hgNAFL was 2.39 (95% confidence interval, 1.55-3.68). The OR remained significant after adjustment for Cr, TG, BMI, and HOMA-IR. CONCLUSIONS: Our findings suggest an independent association of serum FGF-21 with NAFL in Korean men with type 2 diabetes.
