Abstrakt:	Rationale: Lung transplant recipients have the worst long-term outcomes of all solid organs due to acute rejection and chronic lung allograft dysfunction (CLAD). Objective: To investigate the efficacy of ECP as a prophylactic treatment to prevent acute cellular rejection (ACR), CMV infections and reduce the risk of CLAD. Methods: Single-center prospective randomized controlled trial conducted at Medical University of Vienna between 2018 and 2020. It included 31 COPD recipients per group. Treatment group underwent extracorporeal photopheresis in addition to standard triple-drug immunosuppression protocol after lung transplantation. Control group received standard triple-drug immunosuppressive therapy. The primary outcome was a composite outcome defined as incidence of high-grade ACR, CMV infection or CLAD within 24 months after lung transplantation. Results: In the control group, 19 patients (61.3%) achieved the primary combined endpoint, compared with only 6 patients (19.4%) in the treatment group (p<0.001). Freedom from high-grade ACR was significantly greater in the ECP group (p=0.045). Cumulative A scores were significantly lower in the ECP group than in the control group at 3 months (0.18±0.44 versus 0.56±0.94, p<0.05) and at 12 months (0.25±0.48 versus 1.0±1.45, p=0.002). The rate of infections was lower in the ECP group with 5 cases and 67 cumulative hospital days compared to 22 cases and 309 days in the control group (p=0.002). Freedom from CLAD at three years was significantly greater in the ECP group (p=0.015). Conclusion: Adding ECP to standard triple immunosuppression resulted in a significant reduction of the number of ACR episodes and significantly lower incidence of CLAD. (Copyright ©The authors 2024.
