Abstract:
Background: Sirolimus, one of the immunosuppressive drugs administered to renal transplant recipients,
is metabolized by cytochrome P450 (CYP) 3A5. Accordingly, CYP3A5 polymorphism is a genetic
factor affecting sirolimus pharmacokinetics (PK). Therefore, we conducted a systematic review and meta-analysis
on the association between sirolimus PK and CYP3A5*3 polymorphism.
Methods: We searched for studies published up to 13 June 2024 from PubMed, Embase, Cochrane Library,
and Web of Science. We reviewed studies on the relationship between CYP3A5*3 polymorphism and weightadjusted
trough concentration/dose (C0 /D) ratio and dosage of sirolimus in renal transplant recipients, according
to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We evaluated
mean differences (MDs) and 95% confidence intervals (CIs).
Results: A total of seven studies were included. The weight-adjusted C0 /D ratio of sirolimus was significantly
higher in patients with the CYP3A5*3/*3 rather than CYP3A5*1/*1 or CYP3A5*1/*3 genotype (MD 95.27
ng/mL per mg/kg; 95% CI: 58.06, 132.47; I2 = 74%; p < 0.00001). Also, the weight-adjusted dosage of sirolimus
was significantly lower in patients with the CYP3A5*3/*3 rather than CYP3A5*1/*1 or CYP3A5*1/*3
genotype (MD -2.60 × 10-3 mg/kg; 95% CI: -4.52, -0.69; I2 = 44%; p = 0.008).
Conclusion: Our meta-analysis showed a significant effect for the CYP3A5*3 genotype on weight-adjusted
C0 /D ratio and dosage of sirolimus in adult renal transplant recipients.
