Healing of foot ulcers in immunosuppressed renal transplant patients.

Sixteen renal transplant patients were retrospectively studied to determine the time foot ulcerations healed. All patients were taking imuran and medrol. More recently, patients were also on cyclosporine. All were insulin-dependent diabetics. A control group was established from a pool of randomly selected, age-matched, insulin-dependent diabetics who were also observed for foot ulcerations. All treatment was given by one physician. Pulse volume recordings were obtained in all but eight patients, who were clinically believed to have normal vascular supply to the affected extremity. No statistically significant difference was found between these groups in this regard. Cultures were obtained in all patients when indicated; appropriate antibiotics were started. No major differences were noted with respect to infecting organism. The immunosuppressed group had no excellent results, and three good, 14 fair, and 23 poor results. The control group had ten excellent, 14 good, 11 fair, and 17 poor results. A higher failure rate may occur with limb-salvage surgery in the immunosuppressed patient. This observation confirms a long-held clinical suspicion.
