We investigated the effect of pregnane X receptor (PXR) polymorphisms on tacrolimus (FK506) blood trough concentrations and the associated adverse reactions in kidney transplantation recipients (KTRs). Polymerase chain reaction (PCR)-restriction fragment length polymorphism was used to detect the genotypes of single nucleotide polymorphism loci in 336 KTRs. The PXR six-base deletion mutation was classified using specific allele PCR, and the FK506 blood trough concentration in the KTRs was measured by chemiluminescent microparticle immunoassay.

Effect of CYP3A5 gene polymorphisms on tacrolimus concentration/dosage ratio in adult liver transplant patients

We examined the influence of the cytochrome P450 3A5 (CYP3A5) genes in both donors and recipients on the concentration-dosage ratio (C/D) of tacrolimus in Chinese liver transplant patients. Fifty-one adult liver transplant patients who received tacrolimus were included in this study. The CYP3A5 polymorphism in donors and recipients was determined at the time of transplantation, and tacrolimus-based immunosuppressive therapy was started based on each patient’s genetic constitution.
