摘要:

文题释义:
BK病毒:是多瘤病毒家族亚型之一,属于DNA小颗粒病毒。健康人群存在BK病毒隐性感染史者较为普遍,一般无明显临床症状,但当肾移植受者接受免疫抑制治疗时,病毒可在体内再激活,感染率升高现象尤为突出。
CYP3A5:细胞色素P450酶3A5,即细胞色素P450基因,第3家族,A亚家族,第5多肽链。主要参与内源性和外源性化合物(包括大多数临床药物)的代谢。

背景:BK病毒是一种易感性多瘤病毒。近年来,随着新型强效免疫抑制剂的广泛应用,肾移植后BK病毒感染率不断升高,由其导致的 BK病毒性肾病已成为移植肾失功的重要原因之一,目前尚缺乏有效的药物预防或治疗BK病毒性肾病。确定肾移植后BK病毒感染的高危人群,有助于及时发现并早期防控BK病毒性肾病。
目的:研究他克莫司代谢率与肾移植移植后早期BK病毒感染的关系。
方法:选择2017年1月至2018年12月在解放军北部战区空军医院接受肾移植的62例受者,均采用一代基因测序检测患者CYP3A5基因多态性,然后根据基因检测结果分为快代谢组(CYP3A5*1/*1基因型或*1/*3基因型)(n=28)和慢代谢组(CYP3A5*3/*3基因型)(n=34)。手术均经解放军北部战区空军医院伦理委员会批准。研究经解放军北部战区空军医院伦理委员会批准。
结果与结论:快代谢组受者移植后1,3,6,12个月的他克莫司代谢率明显低于慢代谢组受者。快代谢组BK病毒血症的发生率高于慢代谢组,而两组BK病毒尿症和BK病毒性肾病发生率接近。提示CYP3A5*1/*1和*1/*3基因型的肾移植受者移植后早期BK病毒血症发生风险比CYP3A5*3/*3基因型较高。

Abstract: BACKGROUND: BK virus is a kind of polyomavirus. In recent years, with the widely application of new powerful immunosuppressants, BK virus infection rate is continuously rising after renal transplantation. Kidney diseases caused by BK virus nephropathy have become one of the important reasons for renal allograft loss. However, there is a lack of effective antiviral drugs to prevent or treat BK virus nephropathy. Identifying the high-risk population of BK virus infection after kidney transplantation will help in the timely detection and early prevention and control of BK virus nephropathy.
OBJECTIVE: To study the relationship between the metabolic rate of tacrolimus and early BK virus infection after kidney transplantation. 
METHODS: A total of 62 kidney transplant recipients from January 2017 to December 2018 in Air Force Hospital of PLA Northern Theater Command were selected for detection of CYP3A5 gene polymorphism by gene sequencing, and then were divided into fast metabolites (CYP3A5*1/*1 or *1/*3 genotype; n=28) and slow metabolites (CYP3A5*3/*3 genotype; n=34), according to the gene detection results. All surgeries were approved by the Ethics Committee of the Air Force Hospital of PLA Northern Theater Command. The study protocol was also approved by the Ethics Committee of Air Force Hospital of Northern Theater Command.
RESULTS AND CONCLUSION: The tacrolimus metabolic rates at 1, 3, 6 and 12 months after surgery were significantly lower in the fast metabolite group than the slow metabolite group, and the incidence rates of BK viruria and BK virus nephropathy were similar between the two groups. These findings suggest that kidney transplant recipients with CYP3A5*1/*1 and *1/*3 genotypes have a higher risk of early BK viremia after kidney transplantation than those with CYP3A5*3/*3 genotypes.
