Impact of the Age Difference Between the Donor and Recipient on the Morbidity and Mortality After Lung Transplantation. Study on a National Multicenter Cohort (COLT)

Lung Transplantation

It is commonly accepted that the characteristics of the organ donor impact on the future post transplant. In lung transplantation (LP), the defining characteristics of the ideal donor includes an age less than 55 years. However, before the pulmonary graft shortage with a corresponding mortality still too high waiting list, the lung graft acceptance criteria were reassessed permitting criteria extension ( marginal graft). And were grafted, depending on the urgency and accessibility problems in the registry of potential candidate, organs from donors aged 55 and older with quite comparable to those obtained from younger donors . Nevertheless, it is common practice that the grafts from older donors are more readily allocated to older candidates and the most severe, as many confounding factors to assess the real impact of donor age on post-transplant evolution on small cohorts. The main goal of this study is to compare the survival of lung transplant patients depending on the age difference between donor and recipient. The study will be conducted from a broad national cohort of lung transplant patients registered in COLT ( Lung Transplantation COhort). Established in September 2009, promoted by the University Hospital of Nantes, COLT involves 11 lung transplant centers authorized on French territory. It provides a standardized common longitudinal monitoring of the recipient from his transplant. Currently more than 1,000 patients included in this study are transplanted.
