摘要:

本研究通过回顾性队列研究, 明确CYP2C9*3和CYP4F2 rs2108622基因多态性对华法林治疗相关的过度抗凝和出血并发症的影响。共纳入196例患者, 其中男性80例, 平均年龄50.8±10.7岁, 平均随访26.9±11.8个月。患者行心脏瓣膜置换术后且服用华法林3个月以上, 目标国际标准化比值(INR)控制在1.8–2.5。采用聚合酶链反应(PCR)-基因测序法检测CYP2C9*3和CYP4F2 rs2108622基因型, 采用SPSS19.0软件分析基因型与华法林相关过度抗凝和出血并发症的关系。在434患者年中, 共发生严重出血18例, 轻度出血59例。与*1/*1携带者相比, CYP2C9*1/*3患者存在更高的过度抗凝风险(HR 7.10; 95% CI: 2.54–19.79, P < 0.001)。CYP4F2 rs2108622突变基因型不显著增加出血(HR 0.89; 95% CI: 0.43–1.82, P = 0.74)或过度抗凝(HR 0.43; 95% CI: 0.16–1.13, P = 0.09)风险。Kaplan-Meier生存曲线显示, CYP2C9 *1/*3携带者过度抗凝时间明显短于*1/*1携带者(log-rank检验, P < 0.001), 而CYP4F2 rs2108622突变基因型患者过度抗凝时间较野生型患者长(P = 0.05)。CYP2C9*3CYP4F2 rs2108622可能是中国患者华法林治疗中过度抗凝的主要预测因素。

Abstract:

In this retrospective cohort study, we aimed to identify the influence of the CYP2C9*3 and CYP4F2 rs2108622 gene alleles on over-anticoagulation and bleeding complications associated with warfarin therapy. A total of 196 patients were included, including 80 males, the mean age was 50.8±10.7 years, and the average follow-up was 26.9±11.8 months. These patients underwent heart valve replacement surgery in the Cardiovascular Surgery of Fujian Provincial Hospital between January 2018 and August 2019, who took warfarin for at least 3 months and had target international normalized ratio (INR) between 1.8 and 2.5. Genotypes of CYP2C9*3 and CYP4F2 rs2108622 genes were tested by polymerase chain reaction (PCR)-gene sequencing technique. SPSS19.0 software was utilized to analyze the association between genotypes and warfarin-related over-anticoagulation and bleeding complications. Of the 434 patient-years, 18 severe bleedings and 59 mild ones occurred in 31 patients. Patients with CYP2C9 *1/*3 were associated with a higher over-anticoagulation risk compared with the *1/*1 carriers (hazard rate (HR) 7.10; 95% confidence interval (CI): 2.54–19.79, P < 0.001). The CYP4F2 rs2108622 mutant genotype did not cause significant increase in bleeding risk (HR 0.89; 95% CI: 0.43–1.82, P = 0.74) or over-anticoagulation (HR 0.43; 95% CI: 0.16–1.13, P = 0.09). Meanwhile, Kaplan-Meier survival curves showed that the time to over-anticoagulation in CYP2C9 *1/*3 carriers was significantly shorter compared with the *1/*1 carriers (log-rank test, P<0.001), while that in CYP4F2 rs2108622 mutant genotype patients was longer compared with the wild-type patients (P = 0.05). CYP2C9*3 and CYP4F2 rs2108622 might be major predictive factors of over-anticoagulation for warfarin therapy in Chinese patients.
