摘要：

Background The donor liver grafts with different allelic patterns do not affect CYP2C19 genotypes in the peripheral blood of living donor liver transplantation (LDLT) recipients. Aim This study investigated the influence of graft liver CYP2C19 genotypes on recipients who received the same or different CYP2C19 genotypes from donors after LDLT. Methods There were 30 donors and 30 recipients with the same CYP2C19 genotypes and 47 donors and 47 recipients with different CYP2C19 genotypes. Genomic DNA was isolated from the liver tissue of recipients. The CYP2C19 haplotypes were determined by polymerase chain reaction. Results A homogenous phenomenon in the sequences of graft liver CYP2C19 genotypes was indicated because the recipients showed mixed patterns that were similar to that of the original donor after LDLT. A significant decrease in homozygous extensive metabolizer (HomEM) and an increase in poor metabolizer (PM) distribution were observed in recipients with different CYP2C19 genotypes from their donors compared with recipients with the same CYP2C19 genotype as their donors (P < 0.05). Conclusions Homogenous phenomenon of sequence changes in graft liver CYP2C19 from the different genotypes between the donors and the recipients may play a role in graft stability by causing decreased HomEM and increased PM after LDLT.
