Correlation between the adiponectin-leptin ratio and parameters of insulin resistance in patients with type 2 diabetes.
Metabolism. 2005 Mar; 54(3):281-6.M

Abstract

We studied the correlation between the adiponectin-leptin (A/L) ratio and parameters of insulin resistance in 220 Japanese patients with type 2 diabetes (138 men and 82 women). Body mass index (BMI), triglycerides (TGs), HDL cholesterol (HDL), and preheparin serum lipoprotein lipase (LPL mass) were examined as laboratory parameters of the insulin resistance. The correlations between these laboratory parameters and adiponectin, leptin, or A/L ratio were studied. Adiponectin levels correlated significantly with BMI (r = -0.298, P = .0003), TGs (r = -0.221, P = .0092), HDL (r = 0.31, P = .0002), and LPL mass (r = 0.26, P = .0021) in men, and with TGs (r = -0.29, P = .0093), HDL (r = 0.239, P = .0338), and LPL mass (r = 0.499, P < .0001) in women. Leptin levels correlated significantly with only BMI (r = 0.31, P = .0002) in men, and with BMI (r = 0.71, P < .0001) and TGs (r = 0.26, P = .0201) in women. Adiponectin and leptin levels tended to correlate with these parameters in an opposite manner. On the other hand, A/L ratio significantly correlated with BMI (r = -0.4, P < .0001), TG (r = -0.199, P = .0192), HDL (r = 0.235, P = .0054), and LPL mass (r = 0.244, P = .0390) in men, and with BMI (r = -0.482, P < .0001), TG (r = -0.402, P = .0002), HDL (r = 0.358, P = .0011), and LPL mass (r = 0.487, P < .0001) in women. Next, the patients were divided into 3 groups classified by their fasting plasma glucose (FPG) level, and the correlations between the parameters and A/L ratio or homeostasis model assessment (HOMA-R), and the correlation between A/L ratio and HOMA-R were investigated in each group. Significant correlations between the parameters and A/L ratio were tended to be observed as the FPG level rose; however, the significant correlations between the parameters and HOMA-R were no longer seen as FPG level elevated. The results suggested that the A/L ratio was effective in relevance as a parameter of insulin resistance to adiponectin or leptin alone, and a more sensitive and reliable marker of insulin resistance than HOMA-R as the FPG level elevated, in patients with type 2 diabetes.
