Abstract

Objective: This study aimed to investigate the combined effect of CYP3A5*3, CYP3A4*22, and POR*28 genetic polymorphisms on tacrolimus and cyclosporine dose requirements.

Methods: One hundred thirty renal transplant patients placed on either tacrolimus or cyclosporine were recruited, where the effect of CYP3A5*3, CYP3A4*22, and POR*28 genetic polymorphisms on their dose requirements were studied at days 14, 30, and 90 post-transplantations.

Results: The POR*28 allele frequency in the studied population was 29.61%. The tacrolimus dose-adjusted trough concentration ratio (C0/D) was significantly lower in the fast metabolizers group ( CYP3A5*1/POR*28(CT/TT ) carriers) than in the poor metabolizers group ( CYP3A5*3/*3/CYP3A4*22 carriers) throughout the study (14, 30, and 90 days) ( P = 0.001, <0.001, and 0.003, respectively). Meanwhile, there was no significant effect of this gene combination on cyclosporine C0/D.

Conclusion: Combining the CYP3A5*3, POR*28 , and CYP3A4*22 genotypes can have a significant effect on early tacrolimus dose requirements determination and adjustments. However, it does not have such influence on cyclosporine dose requirements.

CYP3A4*22、CYP3A5*3和POR*28基因多态性对早期肾移植患者钙调磷酸酶抑制剂剂量需求的影响

目的:本研究旨在探讨CYP3A5*3、CYP3A4*22和POR*28基因多态性对他克莫司和环孢素剂量需求的联合影响。方法:招募130例接受他克莫司或环孢素治疗的肾移植患者，在移植后第14、30和90天研究CYP3A5*3、CYP3A4*22和POR*28基因多态性对其剂量需求的影响。结果:研究人群中POR*28等位基因频率为29.61%。研究期间(14、30、90天)，快速代谢组(CYP3A5*1/POR*28(CT/TT)携带者)的他克莫司剂量调整谷浓度比(C0/D)显著低于代谢不良组(CYP3A5*3/*3/CYP3A4*22) (P = 0.001)。结论:结合CYP3A5*3、POR*28、CYP3A4*22基因型对早期他克莫司剂量需求的确定和调整有显著影响。然而，它对环孢素的剂量要求没有这样的影响。

期刊介绍： Pharmacogenetics and Genomics is devoted to the rapid publication of research papers, brief review articles and short communications on genetic determinants in response to drugs and other chemicals in humans and animals. The Journal brings together papers from the entire spectrum of biomedical research and science, including biochemistry, bioinformatics, clinical pharmacology, clinical pharmacy, epidemiology, genetics, genomics, molecular biology, pharmacology, pharmaceutical sciences, and toxicology. Under a single cover, the Journal provides a forum for all aspects of the genetics and genomics of host response to exogenous chemicals: from the gene to the clinic.
