Extracorporeal Photopheresis, a Therapeutic Alternative for T cell-mediated Rejection in Renal Transplantation.

T-cell mediated rejection (TCMR) in renal transplantation, although reduced by better immunosuppressants, still impacts graft survival. TCMR responds to methylprednisolone (MPL) in 60% to 70% of cases, with polyclonal anti-T-lymphocyte antibodies (ATGs) used for severe or corticoresistant cases. When ATG is contraindicated, extracorporeal photopheresis (ECP) may be an alternative.
