Abstract
BACKGROUND
The objectives were to investigate the effect of the interaction between peroxisome proliferator-activated receptor gamma (PPAR-γ) Pro12Ala polymorphisms and dietary insulin load and insulin index (DIL and DII) on Cardio-metabolic Markers among diabetic patients.
METHODS
This cross-sectional study was conducted on 393 diabetic patients. Food-frequency questionnaire (FFQ) was used for DIL and DII calculation. PPAR-γ Pro12Ala was genotyped by the PCR-RFLP method. Biochemical markers including TC, LDL, HDL, TG, SOD, CRP, TAC, PTX3, PGF2α. IL18, leptin and ghrelin were measured by standard protocol.
RESULT
Risk-allele carriers (CG, GG) had higher obesity indices WC (P interaction =0.04), BMI (P interaction =0.006) and, WC (P interaction =0.04) compared with individuals with the CC genotype when they consumed a diet with higher DIL and DII respectively. Besides, carriers of the G allele who were in the highest tertile of DIL, had lower HDL (P interaction =0.04) and higher PGF2α (P interaction =0.03) and PTX3 (P interaction =0.03). Moreover, the highest tertile of the DII, showed an increase in IL18 (P interaction =0.01) and lower SOD (P interaction =0.03) for risk allele carriers compared to those with CC homozygotes.
CONCLUSION
We revealed PPAR-γ Pro12Ala polymorphism was able to intensify the effect of DIL and DII on CVD risk factors; risk-allele carriers who consumed a diet with high DIL and DII score have more likely to be obese and have higher inflammatory markers. Also, protective factor against CVD risk factors were reduced significantly in this group compared to CC homozygotes. This article is protected by copyright. All rights reserved.
