AIM: Despite increasing evidence of adiponectin’s anti-inflammatory and antiatherogenic effects, its role in atherogenesis remains uncertain. The aim of the present study is to investigate the association between +45T>G and +276G>T polymorphisms of the adiponectin gene and both plasma adiponectin levels and carotid intima-media thickness in patients with diabetes mellitus type 2.
METHODS: 301 diabetic patients, divided into three categories on the basis on BMI were enrolled in the study. Carotid intima-media thickness (CIMT) was assessed ultrasonographically. Plasma adiponectin levels were measured by enzyme-linked immunosorbent assay (ELISA). Genotypes were determined by real-time PCR.
RESULTS: Adiponectin level and prevalence of the G allele of 45T>G polymorphism decreased significantly with increasing BMI category. G allele of +45T>G polymorphism was associated with higher plasma adiponectin level only after adjustment for age, sex and BMI. No statistically significant difference in CIMT and +276T>G genotypes distribution was observed between BMI categories. None of the polymorphisms as well as plasma adiponectin level was associated with CIMT after adjustment for covariates.
CONCLUSION: The G allele of the +45T>G polymorphism is not independently associated with plasma adiponectin level and is not associated with CIMT. +276G>T polymorphism is not associated with plasma adiponectin levels and CIMT in diabetic patients.
