Abstract

Background:

Cyclooxygenase 1 (COX-1), COX-2, and HO-1 are involved in the process of aspirin's effect. The genetic susceptibility of these enzymes to aspirin resistance (AR) is unclear.

Methods:

A total of 431 patients took aspirin. Using arachidonic acid-induced light transmittance aggregation combined with adenosine diphosphate-induced light transmittance aggregation, 36 participants served for AR, 164 participants for semi-AR, and 231 participants for aspirin sensitivity (AS). The AR with 9 single-nucleotide polymorphism in COX-1, COX-2, and HO-1 genes was investigated.

Results:

COX-1 rs1330344 (− 1676A>G) is associated with AR. G-Allele carriers significantly increased the risk of AR. For patients with AS as control, P is .02 (odds ratio [OR] = 1.77, confidence interval [CI]: 1.07-2.92). For patients with semi-AR as control, P is .05. HO-1 rs2071746 (−413A>T) is associated with AR. T-Allele carriers significantly increased the risk of AR. For patients with AS as control, P is .04 (OR = 1.70, CI: 1.02-2.79). For patients with semi-AR as control, P is .05 (OR = 1.68, CI: 1.00-2.80).

Conclusion:

rs2071746 in HO-1 gene, rs1330344 in COX-1 gene contribute to AR.
