Preliminary results of clinical renal allograft transplantation in the dog and cat.

Renal allograft transplantation was performed as treatment for terminal renal failure in six veterinary patients. Three patients failed to survive the postsurgical period, one patient died due to acute allograft rejection, one patient died subsequent to complications of previous parenteral hyperalimentation and infection, and one patient was euthanatized due to the inability of the clients to maintain the effort necessary to manage a transplant recipient. Further clinical studies are necessary to determine if renal transplantation with cyclosporine (cyclosporin A)/prednisolone immunosuppression has the potential to provide practical treatment of terminal renal disease in clinical veterinary medicine. Pharmacologic and immunologic monitoring of transplant recipients with individualized immunosuppression is imperative. Careful surveillance is necessary to identify and eliminate nosocomial sources of infection. Candidates for transplantation cannot be critically ill or malnourished prior to surgery, and pet owners must be prepared for the financial and time commitments associated with caring for a renal allograft recipient.
