Objective To investigate the relationship between the CYP3A5 genotyping and the drug metabolism of tacrolimus after operation in adult liver transplantation.Methods Ninety-eight adult patients with liver transplantation in Tianjin First Center Hospital were selected as subjects. The blood samples of liver transplantation recipients and donor were collected before operation, and then tested the CYP3A5 genotyping by PCR method. The weekly body mass, tacrolimus dose, and drug valley concentration of the patients were monitored in 1, 2, 3, and 4 weeks after operation, to calculate the tacrolimus concentration/dose ratio. And then compared the effects of different genotyping of donor and receptors on tacrolimus concentration/dose ratio.Results In the CYP3A5 genotyping of 98 patients with liver transplantation and the corresponding donors, GG type was the most and AA type was the least, the distribution of alleles was in accordance with the genetic law, and the difference was not statistically significant (P>0.05). According to the donor genotype, the results showed that there was a significant correlation between tacrolimus concentration/dose ratio and donor or recipients CYP3A5 genotype at 1, 2, 3, and 4 weeks after liver transplantation, and there was significant difference among the three groups (P<0.05): GG>AG>AA. According to the combined grouping of donor and receptor genotype, the results showed that there was significant difference in tacrolimus concentration/dose ratio among A*/A*, A*/GG, GG/A*, and GG/GG group (P<0.05), while there was significant difference in tacrolimus concentration/dose ratio between GG/GG and A*/A* group (P<0.01), the tacrolimus concentration/dose ratio was highest in GG/GG group and lowest in A*/A* group.Conclusions The CYP3A5 genotyping of the recipient and donor can affect the blood concentration of tacrolimus after liver transplantation, and the CYP3A5 GG genotype is more likely to reach the target plasma concentration than the other genotypes, that the detection of donor and recipient CYP3A5 genotype in patients with liver transplantation can provide a reference for individualized treatment of tacrolimus after liver transplantation.
