- Abstract
Aims To investigate the effect of two common ATP-binding cassette transporter 1 ( ABCA1) polymorphisms (rs4149263 and rs2020927) on atherogenic dyslipidaemia in Korean Type 2 diabetic patients who were treated with rosiglitazone. Patients and methods Two hundred and fifty-six patients with Type 2 diabetes who had never previously received peroxisome proliferator-activated receptor gamma (PPAR-γ) agonists or lipid-lowering treatment were treated with 4 mg of rosiglitazone daily for 12 weeks without any adjustment to their glucose-lowering regimen. The primary outcome was the change in atherogenic index of plasma (AIP), calculated as log [triglyceride (mmol/l)/high-density lipoprotein cholesterol (mmol/l)], before and after rosiglitazone treatment. The effect of rosiglitazone on the change in AIP was compared across the ABCA1 single nucleotide polymorphisms (SNPs) rs41429263 and rs2020927. Results Before adjustment, the change in AIP at 12 weeks was significantly different across the rs4149263 genotypes [median (interquartile range): −0.05 (−0.21, 0.09) for TT; 0.02 (−0.09, 0.17) for TC; and 0.11 (0.03, 0.25) for CC; P = 0.003], but not across the rs2020927 [−0.04 (−0.18, 0.10) for TT; 0.03 (−0.17, 0.15) for TC; and −0.03 (−0.13, 0.10) for CC; P = 0.401]. After controlling for age, gender and duration of diabetes, the presence of the C-allele was significantly associated with an increase in AIP by 0.13 [95% confidence interval (CI), 0.04–0.21; P = 0.003]. This association did not change significantly when body mass index and pretreatment metabolic parameters were additionally controlled for (the change in AIP: 0.14; 95% CI, 0.04–0.24; P = 0.007). Conclusions The ABCA1 SNP rs4149263 may be associated with the change in atherogenic lipid profile in Type 2 diabetes treated with rosiglitazone.
