Reversal of acute renal allograft rejection by extracorporeal photopheresis: a case presentation and review of the literature.

There is a clear need for well-tolerated immunomodulatory agents that can aid in the prevention of acute solid organ rejection. Extracorporeal photopherosis is an apheresis-based therapy that is currently available at many medical centers worldwide. Preliminary studies utilizing photopheresis with standard immunosuppressives have shown this therapy to successfully reverse acute cellular rejection of cardiac allografts with minimal toxicity. No formal evaluation of the role of extracorporeal photopheresis had been performed in renal transplantation. In this report, photopheresis was successfully utilized to treat acute cellular rejection in a patient with a renal allograft. This lends further support to the existing literature suggesting that photopheresis may be useful for the reversal of acute solid organ rejection. Although our experience with this patient is anecdotal, photopheresis merits further study as treatment for severe renal allograft rejection.
