There is little evidence of the association between CETP SNPs and obesity and/or related metabolic parameters. To analyze the association of the polymorphism rs1800777 of the CETP gene with anthropometric parameters, lipid profile, metabolic syndrome and its components, and adipokine levels in obese subjects without type 2 diabetes mellitus or hypertension. A population of 1005 obese subjects was analyzed. Electrical bioimpedance was performed, and blood pressure, presence of metabolic syndrome, dietary intake, physical activity, and biochemical tests were recorded. Nine hundred and sixty eight patients (96.3%) had the GG genotype, 37 patients the GA genotype (3.7%) (no AA genotype was detected). Fat mass (delta: 4.4±1.1kg; p=0.04), waist circumference (delta: 5.6±2.1cm; p=0.02), and waist to hip ratio (delta: 0.04±0.01cm; p=0.01) were higher in A allele carriers than in non-A allele carriers. HDL cholesterol levels were lower in A allele carriers than in non-A allele carriers (delta: 4.2±1.0mg/dL; p=0.04). In the logistic regression analysis, the GA genotype was associated to an increased risk of central obesity (OR 7.55, 95% CI 1.10-55.70, p=0.02) and low HDL cholesterol levels (OR 2.46, 95% CI 1.23-4.91, p=0.014). The CETP variant at position +82 is associated to lower HDL cholesterol levels, increased fat mass, and central obesity in obese subjects. These results may suggest a potential role of this variant gene in pathophysiology of adipose tissue. Show less

There is few evidence of cholesterol ester transfer protein (CETP) in subjects with obesity and diabetes mellitus. We examined the association of the polymorphism (rs1800777) of CETP gene on anthropometric parameters, lipid profile and adipokines in subjects with obesity and diabetes mellitus type 2. A population of 229 obese subjects with diabetes mellitus type 2 was enrolled. An electrical bioimpedance, blood pressure, dietary intake, exercise and biochemical analyses were recorded. Two hundred and seventeen subjects (94.8%) had genotype GG and 12 GA (5.2%) (genotype AA was not detected). Weight (delta: 14.4 ± 2.1 kg, p = 0.01), body mass index (delta: 2.2 ± 1.1 kg/m2, p = 0.01), fat mass (delta: 11.2 ± 3.1 kg, p = 0.02), waist circumference (delta: 3.9 ± 2.0 cm, p = 0.02), waist to hip ratio (delta: 0.04 ± 0.02 cm; p = 0.01), tryglicerides (delta: 48.6 ± 9.1 mg / dl, p = 0.03) and leptin levels (delta: 58.6 ± 15.9 mg/dl, p = 0.02) were higher in A allele carriers than non A allele carriers. Levels of HDL-cholesterol were lower in A allele carriers than non-carriers (delta: 5.6 ± 1.1 mg/dl, p = 0.03). In regression analysis, HDl cholesterol, weight and fat mass remained in the model with the SNP. Our results show an association of this CETP variant at position +82 on HDL cholesterol, levels and adiposity parameters in obese subjects with diabetes mellitus type 2. Show less
