Pilot evaluation of 15-deoxyspergualin for refractory acute renal transplant rejection.
15-deoxyspergualin (DSG) is a novel immunosuppressant which has been shown to be effective in preventing and treating rejection in animal allo- and xenotransplant models. Preliminary clinical studies suggest that DSG is an effective antirejection agent. In our study, 4 patients with biopsy-proven rejection episodes that were resistant to steroid and antibody therapy were then treated with DSG. All 4 rejection episodes responded to DSG therapy and all 4 kidneys continue to function (follow-up 7-15 months). However, 2 patients had additional rejection episodes after DSG therapy. Side effects during DSG treatment were minimal; 1 patient, who had also had multiple courses of antibody, developed a lymphoproliferative tumor 2 months after DSG administration. We conclude that DSG is effective in treating refractory renal transplant rejection episodes. Additional studies are necessary to determine the ideal place for DSG in treating renal transplants recipients with rejection.
