Abstract:
Objective To assay the plasma omentin level in patients of type 2 diabetes mellitus (T2DM) combined with non-alcoholic fatty liver disease (NAFLD) and investigate the relationship between plasma omentin level,glucose and lipid metabolism,insulin resistance and NAFLD.Methods The plasma omentin level was assayed by enzyme-linked immunosorbent assay(ELISA) in all subjects,including patients of T2DM controls with NAFLD (group A,50 cases),T2DM without NAFLD (group B,50 cases),simple with NAFLD(group C,51 cases) and normal controls (group D,49 cases).Meanwhile,blood glucose,glycosylated hemoglobin(HbA1c),lipids and insulin levels were also measured.Body mass index (BMI) and waist-to-hip ratio were evaluated.Insulin sensitivity was assessed by HOMA-IR.Results The plasma omentin level was (17.85 ±3.68),(13.89 ±10.68),(26.05 ±7.26) and (22.92 ±2.71)μg/L in group A,B,C and D respectively.The plasma omentin level of group A and group B was significantly lower than that of group C and group D(P ＜ 0.05).The plasma omentin level of group A was higher than that of group B (P ＜ 0.05).The plasma omentin level of group C was higher than that of group D (P＜ 0.05).Correlation analysis showed that the plasma omentin level was negatively correlated to weight,BMI,waist,triglyceride,fasting blood glucose,fasting insulin (FINS) and HOMA-IR (P ＜0.05 or ＜0.01),and positively correlated to high-density lipoprotein cholesterol (HDL-C)(P ＜0.01).Multiple stepwise regression analysis showed that BMI,HOMA-IR and FINS was independent variable of omentin.The concentration of omentin was 24.82 μ g/L which could predict the risk of NAFLD in people with normal glucose regulation.Conclusions The plasma omentin level is closely correlated with glucose,lipid metabolism and insulin resistance.Plasma omentin may play an important role in the pathogenesis of T2DM and NAFLD.
