Abstract

Abstract : Objective: This study aimed to explore the association between GPIa, COX‐2 gene polymorphisms and aspirin resistance in the ischemic stroke patients from the southern part of Jiangsu province. Methods: In all, 97 patients with acute ischemic stroke were enrolled in the study. GPIa gene polymorphism at 807C>T (rsl126643) locus and COX‐2 gene polymorphism at ‐765G>C (rs20417) locus were genotyped by PCR pyrosequencing technology. Patients were divided into the aspirin sensitivity (AS) group and aspirin resistance (AR) group according to the platelet aggregation rate. The relationship between the two gene polymorphisms and aspirin resistance was investigated and analyzed. Results: The distribution of the genotype (CC, CT, TT, CT + TT, and CC) and the frequency of allele T of GPIa gene at 807C>T locus were significantly different in AS and AR groups in female patients ( P < .05). Logistic regression analysis showed that the genotype of CT+TT at 807C>T locus was significantly correlated with AR after adjustment for relative factors ( P = .047, OR = 4.856, 95% CI: 1.020–23.108). There were no significant differences in the genotype distribution and allele frequency of the COX‐2 gene ‐765G>C site between two groups ( P > .05). Conclusion: GPIa gene polymorphism at 807C>T locus was associated with AR in Chinese Han females, and the expression of allele T increased the incidence of AR. The gene polymorphism of COX‐2 gene at ‐765G>C locus was not significantly correlated with AR.
