Obliterative Bronchiolitis (OB) is the major cause of long-term lung allograft loss for patients with end stage pulmonary diseases like cystic fibrosis. Numerous cells and proteins are implicated in this process, which have never been studied prospectively in a multicentric longitudinal cohort. The aim of this study is to detect predictive risk factors of OB through a national multicentric cohort of 500 newly transplanted recipients (COLT). COLT will consist in a large database, associated with a recipient bio-collection, and specific projects using these resources. COLT will aggregate all the 11 French centres of pulmonary transplantation. Patient will be followed-up during 5 years. Blood samples will be obtained. Induced sputum, bronchoalveolar lavage fuid, exhaled breath condensate and trans bronchial biopsies will be also taken. T cells, known to be involved in chronic rejection will be studied, and genomic, microarray and proteomic approaches will be used to detect further predictive factors. A study on Circulating Endothelial Cells and Circulating Endothelial Progenitors is also realised from blood samples. COLT will prove molecular markers to be predictive of early OB, before the development of severe airway obstruction and will allow the identification of patients at high risk of OB. COLT will identify potential targets for future treatments of OB. This collaborative project makes research and clinical teams working together, and creates the conditions of a long term network, extendable to other laboratories with new projects and additional European transplant centres.

Further study details as provided by Nantes University Hospital:

Primary Outcome Measures:
  • Identification of predictive factors for lung chronic rejection outcome in lung transplant recipients. This primary outcome will be evaluated at the end of the study. [ Time Frame: 8 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Evaluate the pertinence of a monitoring of lung chronic rejection based on the predictive factors identified in the study, in order to prevent this rejection. The secondary outcome measure will be evaluated at the end of the study. [ Time Frame: 8 years ] [ Designated as safety issue: No ]

Enrollment: 700
