OBJECTIVE: Single nucleotide variants (SNVs) of ADIPOQ gene on different comorbidities are related to obesity and weight loss. Despite, there are no studies evaluating the effect of rs3774261 on metabolic variables after bariatric surgery. We evaluated the effect of SNV rs3774261 of ADIPOQ gene on biochemical changes after biliopancreatic diversion surgery in morbidly obese subjects for 3 years follow-up.
PATIENTS AND METHODS: One hundred and forty-nine patients (111 females/38 males) with morbid obesity (body mass index >40 kg/m2) without diabetes mellitus type 2 were enrolled. Biochemical and anthropometric evaluation were registered before and after 1, 2, and 3 years. Genotype of rs3774261 has been studied.
RESULTS: Total cholesterol, LDL-cholesterol and triglyceride levels decreased in all genotype groups during the study. Although the improvement in glucose, insulin and HOMA-IR was significant in two genotypes (AA and AG); these changes were earlier in the AA genotype than in Ag and GG genotypes. Adiponectin levels increased in a significant way in subjects with AA genotype in the 3 follow-up periods (first year delta: 16.4±0.5 ng/ml; p=0.03, second year delta: 21.3±0.5 ng/ mL; p=0.02 and third year delta: 23.6±0.7 ng/mL; p=0.01) and at 3 years in subjects with AG genotype (delta: 18.3±0.4 ng/ mL; p=0.03). The ratio adiponectin/leptin increased in a significant way in subjects with AA genotype in the 3 follow-up times (first year delta: 0.40±0.1 units; p=0.02, second year delta: 0.58±0.1 units; p=0.01 and third year delta: 0.65±0.1 ng/mL; p=0.01) and at 3 years in subjects with AG genotype (delta: 0.61±0.1 ng/ mL; p=0.02). Subjects with GG genotype did not show a significant improvement in these parameters during the follow-up.
CONCLUSIONS: G allele carriers of rs3774261 showed a delay in the improvement of glucose metabolism parameters, adiponectin and adiponectin/leptin ratio.Free PDF Download
