Serum resistin is related to plasma HDL cholesterol and inversely correlated with LDL cholesterol in diabetic and obese humans

Plasma cholesterol, triglycerides and serum resisistin may all be influenced by diabetes and obesity, but their associations remain unclear. Therefore, we put forward a hypothesis that serum lipids might be parallel to resistin, as they all reflect the metabolic status of obese humans. We measured the concentrations of resistin, total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C) and triglycerides (TG) in 134 obese non-diabetic (73 women and 61 men) and 65 obese diabetic (33 women, 32 men) humans, and examined their interrelations. Obesity was defined according to the WHO criterion (BMI, ≥ 30 kg/m²) The presence of diabetes was the only differentiating factor between two groups of frankly obese humans. Non-diabetic vs. diabetic, median and interquartile range, respectively: resistin (ng/mL) 26.08, 16.09 vs. 22.37, 14.54, p=0.736; TC (mmol/L) 5.02, 1.39 vs. 5.16, 1.56, p=0.374; HDL-C (mmol/L): 1.10, 0.41 vs. 1.02, 0.47 p
