ABSTRACT
OBJECTIVE@#To assess the association of cytochrome P450 (CYP450) gene polymorphisms with the occurrence of ischemic stroke (IS).@*METHODS@#From January 2020 to August 2022, 390 IS patients treated at the Zhengzhou Seventh People's Hospital were enrolled as the study group, and 410 healthy individuals undergoing physical examination during the same period were enrolled as the control group. Clinical data of all subjects were collected, which included age, sex, body mass index (BMI), smoking history and results of laboratory tests. Chi-square test and independent sample t test were used for comparing the clinical data. Multivariate logistic regression analysis was used to analyze the non-hereditary independent risk factors for IS. Fasting blood samples of the subjects were collected, and the genotypes of rs4244285, rs4986893, rs12248560 of the CYP2C19 gene and rs776746 of the CYP3A5 gene were determined by Sanger sequencing. The frequency of each genotype was calculated by using SNPStats online software. The association between the genotype and IS under the dominant, recessive and additive models was analyzed.@*RESULTS@#The levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), apolipoprotein B (Apo-B) and homocysteine (Hcy) of the case group were significantly higher than those of the control group, whilst the levels of high density lipoprotein (HDL-C) and Apo-A1 (APO-A1) were significantly lower (P < 0.05). Multivariate Logistic regression analysis showed that TC (95%CI = 1.13-1.92, P = 0.02), LD-C (95%CI = 1.03-2.25, P = 0.03), Apo-A1 (95%CI = 1.05-2.08, P = 0.04), Apo-B (95%CI = 1.7-4.22, P < 0.01) and Hcy (95%CI = 1.12-1.83, P = 0.04) were non-genetic independent risk factors for the occurrence of IS. Analysis of the association between the genetic polymorphisms and the risk of IS showed that the AA genotype at rs4244285 of the CYP2C19 gene, the AG genotype and A allele at rs4986893 of the CYP2C19 gene, and the GG genotype and G allele at rs776746 of the CYP3A5 gene were significantly associated with IS. Under the recessive/additive model, dominant model and dominant/additive model, polymorphisms of the rs4244285, rs4986893 and rs776746 loci were also significantly associated with the IS.@*CONCLUSION@#TC, LDL-C, Apo-A1, Apo-B and Hcy can all affect the occurrence of IS, and CYP2C19 and CYP3A5 gene polymorphisms are closely associated with the IS. Above finding has confirmed that the CYP450 gene polymorphisms can increase the risk of IS, which may provide a reference for the clinical diagnosis.
