Abstract
PURPOSE: Glucocorticoids are used to prevent chronic lung allograft dysfunction (CLAD) after lung transplantation (LT). Our study was aimed at assessing the association between the glucocorticoid-induced transcript 1 gene (GLCCI1) variant, which modulates glucocorticoid sensitivity, and the postoperative lung function and development of CLAD after LT. METHODS: A total of 71 recipients of LT were genotyped for the GLCCI1 variant (rs37972) and divided into three groups: the homozygous mutant allele (TT) group, the heterozygous mutant allele (CT) group, and the wild-type allele (CC) group. The results of pulmonary function tests were compared with the postoperative baseline values. RESULTS: The total lung capacity (TLC) in the TT group was significantly lower than that in the CC group at 3 years after LT (P = 0.029). In the recipients of cadaveric LT, the TLC and forced expiratory volume in 1 s in the TT group were significantly lower than those in the CC groups, resulting in a significant worse CLAD-free survival at 3 years after LT (P = 0.016). CONCLUSION: The GLCCI1 variant was associated with a significant decrease of the TLC at 3 years after LT and the development of CLAD at 3 years, especially in patients undergoing cadaveric LT.
