Abstract:
OBJECTIVE:To investigate the association of synergistic effects of Wuzhi capsules on tacrolimus with CYP3A5*3 (6986A>G,rs776746) gene polymorphisms. METHODS:One hundred and severty patients underwent renal transplantation receiving tacrolimus maintenance therapy after surgery were selected from our hospital during Jan. 1997-Dec. 2015,and then divided into Wuzhi capsules(+)group(74 cases)and Wuzhi capsules(-)group(96 cases)according to the use of Wuzhi capsules. Both groups received tacrolimus+mycophenolate mofetil+prednisone;Wuzhi capsules (+)group was additionally given Wuzhi capsules,one capsule each time,bid,for more than 12 months. Trough concentration of tacrolimus was detected by CMIA 0,1,3,6,12 months after medica-tion,and the blood concentrations(C0/D)were calculated at different time points after correcting daily dose. CYP3A5*3 gene polymor-phisms was detected by PCR-RFLP. The association of C0/D value with gene polymorphism was investigated by analysis of covariance. RESULTS:Among 170 patients,there were 65 cases of CYP3A5 GG genotype,83 cases of AG genotype and 22 cases of AA geno-type;genotype frequencies were 38.2%,48.8% and 12.9%,which was in line with Hardy-Weinberg balance (P>0.05). There was statistical significance in the distribution frequencies of GG,AG+AA genotype between Wuzhi capsules(+)group and Wuzhi capsules (-)group (P<0.05). After 1 month of medication,C0/D of tacrolimus in GG genotype was significantly higher in Wuzhi capsules (+)group than in Wuzhi capsules(-)group. After 1,3,6,12 months of medication,C0/D of tacrolimus in AG+AA genotype was sig-nificantly higher in Wuzhi capsules(+)group than in Wuzhi capsules(-)group,with statistical significance(P<0.05). There was no statistical significance in C0/D of tacrolimus in GG genotype between 2 groups after 3,6,12 months of treatment(P>0.05). CON-CLUSIONS:Wuzhi capsules can increase C0/D of tacrolimus in CYP3A5*3 AG+AA genotype,but have no significant effect on C0/D of tacrolimus in GG genotype;CYP3A5*3 genotype should be considered when using Wuzhi capsules as synergist of tacrolimus.
