Abstract
BackgroundWe aimed to explore the relationship between serum fibroblast growth factor 19 (FGF19) and the atherogenic index of plasma (AIP) in type 2 diabetic patients.MethodsSerum FGF19 levels and lipid profiles were measured in 200 patients with type 2 diabetes (T2D). The levels of serum FGF19 were measured by ELISA. Lipid profiles were measured by enzymatic analysis. AIP and NAFLD fibrosis scores were calculated.ResultsT2D patients showed a significant decreasing trend of FGF19 concentrations depending on the tertiles of AIP (p for trend < 0.05). Simultaneously, the AIP level was closely related to the serum FGF19 level (p < 0.05). Furthermore, after adjusting for age, sex, duration, BMI, hypertension, and diabetic treatment, the correlation was still significant (p < 0.01), and it remained significant even after further adjusting for non-alcoholic fatty liver disease (NAFLD) and NAFLD fibrosis score (NFS) (p < 0.01). However, when stratified by BMI, AIP was positively correlated with FGF19 in normal-weight and overweight T2D patients but not in obese T2D subjects. After adjusting for sex, age, BMI, duration, hypertension, HbA1c, 2hPG, HOMA-IR, AIP, antidiabetic treatments, NAFLD and NFS via multiple stepwise linear regression, AIP was an independent factor affecting serum FGF19 concentrations (SE = 0.238, β = -0.290, p < 0.01).ConclusionsSerum FGF19 levels might be a good predictor for atherosclerosis and cardiovascular disease in T2D patients, especially among non-obese patients; serum FGF19 levels were significantly inversely associated with AIP.
