Abstract
BACKGROUND
The SNP (rs7139228) of the RETN gene is a polymorphism that has been associated with metabolic disorder in subjects with obesity, and its effect on metabolic response after dietary intervention has not been evaluated.
OBJECTIVE
Our objective was to analyse the effects of the polymorphism of the RETN gene rs7139228 on metabolic changes secondary to weight loss with a hypocaloric Mediterranean diet.
DESIGN
1000 obese Caucasian patients were evaluated. An anthropometric evaluation and a biochemical analysis were performed before and after 12 weeks of a hypocaloric Mediterranean diet. The statistical analysis was performed as a dominant model (GG vs GA+AA).
RESULTS
Improvements in anthropometric parameters, leptin levels and systolic blood pressure were similar in both genotype groups. In non- A allele carriers, levels of resistin, insulin, HOMA-IR, triglycerides and C-reactive protein decreased. The improvements were statistically significant in this group; resistin (-1.3+0.1ng/dL: p=0.02), triglycerides (-22.9+4.9mg/dl: p=0.02), CRP (-2.7+0 0.4mg/dl: p=0.02), insulin -6.5+1.8 mIU/L: p=0.02) and HOMA-IR (-2.2+0.8: p=0, 03). In addition, insulin, HOMA-IR and resistin levels were higher in A allele carriers than in non-carriers. Finally, the prevalence of metabolic syndrome and hyperglycaemia were higher in A allele carriers, and these percentages only decreased after intervention in non-A allele carriers.
CONCLUSION
The A rs7139228 allele is associated with a worse metabolic response (insulin, HOMA-IR, triglycerides and CRP) after weight loss with a hypocaloric Mediterranean diet. A non-significant decrease in the prevalence of metabolic syndrome and hyperglycaemia were detected in A allele carriers.
