Abstract:
Background
Atorvastatin is prescribed for the primary and the secondary prevention of coronary artery diseases. A wide variation in inter-individual statin response suggests that genetic differences may contribute to this variation. This study investigated the association of ABCB1 (C3435T) and ABCC1 (G2012T) polymorphisms with clinical response to atorvastatin in Iranian primary hyperlipidemic patients.Methods
Individuals (n=179) with primary hypercholesterolemia were enrolled, and peripheral blood samples were collected. Genotyping of two polymorphisms were performed by amplification refractory mutation system PCR.Results
Following four weeks of treatment, a significant reduction of LDL-C was observed in variant groups (CT) of ABCB1 (P=0.018) and wild-type group (GG) of ABCC1 genes (P=0.029). Logistic regression analysis revealed a significant difference between male and female responses to 10 mg/day atorvastatin (P=0.004, odds ratio=0.2, CI 95%=0.06-0.6).Conclusion
Our finding indicated that these polymorphisms may be attributed to LDL-C serum levels in the primary hypercholesterolemia patients receiving atorvastatin.Keywords:
