Background: Studies in lung transplantation demonstrate that the ancestry and gender dissimilarities of donor-recipients lead to a decrease in survival of the recipient.
Objectives: To evaluate the survival of lung transplant recipients in Israel based on whether the donors and recipients are of Jewish or Arab ancestry as well as survival based on gender match or mismatch.
Methods: We performed a retrospective observational cohort study of 345 lung transplant recipients at the Rabin Medical Center, Petah Tikva, Israel between January 1997 and January 2013. We compared the survival of lung transplant recipients in two ancestry categories: ancestry matched (Jewish donors to Jewish recipients or Arab donors to Arab recipients) and ancestry mismatched (Jewish donors to Arab recipients and vice versa). We also compared the survival among the four gender donor and recipient combinations (male to male, female to female, male to female, and female to male).
Results: Survival analysis revealed no significant differences between the two ancestry groups (P = 0.51) and among the four gender combinations (P = 0.58). On Cox multivariate analysis, younger donor age was the only significant parameter for longer survival (hazards ratio 1.025, 95% confidence interval 1.012-1.037).
Conclusions: Gender and ancestry mismatches in these two Israeli populations do not appear to alter the clinical outcomes following lung transplantation.
