DSA Intragraft in Lung Transplantation: Diagnostic and Prognostic Value in Antibody Mediated Rejection

Not Applicable

Recruiting

• Conditions: Donor Specific Antibodies; Antibody Mediated Rejection; Lung Transplant Recipient

• Registration Number: NCT03702257
• Lead Sponsor: University Hospital, Strasbourg, France

Brief Summary

The diagnosis of AMR in lung transplant recipients is difficult and often comes too late, because of lack of standardized definition. The diagnosis is nowadays based on an expert multidisciplinary approach involving clinical, histopathological and immunological criteria.

Hypothesis: the presence of intragraft donor specific antibodies (gDSAs) could be used as a new diagnostic tool for AMR in lung transplant recipients Study Objectives: to evaluate, in lung transplant patients with circulating DSAs, the diagnostic value of gDSAs in AMR and to analyze its prognostic value on graft outcome.
