He was born with a single kidney with anatomic abnormalities leading to frequent urinary tract infections and end-stage renal disease by age 16. At that time, he received a kidney transplant from a deceased donor, but the allograft failed in 6 years, apparently due to cyclosporine toxicity. At age 22, he received a living-related kidney transplant from his sister. There were 3 out of 6 HLA loci mismatches, one each for A, B and DR between the patient and his sister and he received induction therapy with anti-thymocyte globulin. 4 years later, he had allograft nephrectomy of the first transplant due to pain and shortly thereafter, he stopped taking all his immunosuppressive medications because he lost his insurance and could not afford them.
