Lung Transplant Infection, Lung Transplant Rejection
Conditions
Brief summary
The purpose of this study is to investigate the use of ECP for lung-transplanted patients to reduce the occurrence of acute and chronic rejection and CMV-infection.
Detailed description
The intention of the planned study is the use of ECP as a form of induction treatment in combination with standard triple-drug immunosuppressive therapy (IS). This is a single-center prospective randomized controlled trial conducted at Medical University of Vienna between 2018 and 2020. It includes 31 COPD recipients per group. Treatment group underwent ECP with in addition to IS after lung transplantation. Control group received only IS. The primary outcome was a composite outcome defined as incidence of high-grade ACR, CMV infection or CLAD within 24 months after lung transplantation. Parallel to the clinical parameters, immunologic investigations will be performed to get a better insight into the mechanisms of ECP on the immune system. The dynamics of Tregs and dentritic cell will be analyzed to compare the influence of ECP vs standard IS.
Interventions
Patients who are assigned to the ECP group receive treatments by means of the THERAKOS ® CELLEX ® Photopheresis System (Mallinckrodt Pharmaceuticals Inc.) with either double- or single-needle access. During the leukapheretic processing, 1500 ml of whole blood is processed, and peripheral blood mononuclear cells (MCNs) are separated by centrifugation and collected in the buffy coat. 8-methoxypsoralen (Uvadex®, Mallinckrodt Pharmaceuticals Inc.) at a dose of 20 μg/ml is added to the MNC collection bag and cells are irradiated with ultraviolet A light (1.5 J/cm2) in a 1-mm-thick film through a photoactivation plate. After exposure of the cells to the ultraviolet light, the buffy coat is reinfused into the patient.
