BackgroundWe investigated whether the coronary artery disease (CAD) locus on chromosome 9p21 (as represented by single nucleotide polymorphism rs2383206) is associated with low estimated glomerular filtration rate (eGFR) or increased urinary albumin excretion in patients with Type 2 diabetes mellitus (T2DM).MethodsFour samples, including a total of 3167 patients, were studied. The presence of low eGFR (<60 mL/min/1.73m2) was estimated from serum creatinine by means of the Modification of Diet in Renal Disease Study equation. Increased urinary albumin excretion was defined as an albumin-creatinine ratio (ACR) ≥2.5 mg/mmol in men and ≥3.5 mg/mmol in women.ResultsNo association was found between rs2383206 and low eGFR or increased ACR in each sample as well as in a pooled analysis (overall odds ratio = 1.07, 95% confidence interval 0.94-1.22, P = 0.31 and overall odds ratio = 1.00, 95% confidence interval 0.90-1.12, P = 0.95, respectively). No interaction was observed between rs2383206 and poor glycemic control [HbA1c was above the median in the pooled sample (7.7%) in modulating eGFR or ACR (P for interaction = 0.42 and 0.90, respectively)].ConclusionVariability at the 9p21 CAD locus is unlikely to play a role in modulating susceptibility to kidney dysfunction in patients with T2DM.

Abstract
BackgroundWe investigated whether the coronary artery disease (CAD) locus on chromosome 9p21 (as represented by single nucleotide polymorphism rs2383206) is associated with low estimated glomerular filtration rate (eGFR) or increased urinary albumin excretion in patients with Type 2 diabetes mellitus (T2DM).MethodsFour samples, including a total of 3167 patients, were studied. The presence of low eGFR (<60 mL/min/1.73m2) was estimated from serum creatinine by means of the Modification of Diet in Renal Disease Study equation. Increased urinary albumin excretion was defined as an albumin-creatinine ratio (ACR) ≥2.5 mg/mmol in men and ≥3.5 mg/mmol in women.ResultsNo association was found between rs2383206 and low eGFR or increased ACR in each sample as well as in a pooled analysis (overall odds ratio = 1.07, 95% confidence interval 0.94-1.22, P = 0.31 and overall odds ratio = 1.00, 95% confidence interval 0.90-1.12, P = 0.95, respectively). No interaction was observed between rs2383206 and poor glycemic control [HbA1c was above the median in the pooled sample (7.7%) in modulating eGFR or ACR (P for interaction = 0.42 and 0.90, respectively)].ConclusionVariability at the 9p21 CAD locus is unlikely to play a role in modulating susceptibility to kidney dysfunction in patients with T2DM.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
