Abstract

Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive disorder that results in irreversible renal damage due to 2,8-dihydroxyadenine (DHA) nephropathy. A 28-year-old man underwent living-related kidney transplantation for chronic kidney disease of unknown etiology. Numerous spherical brownish crystals observed in his urinary sediment on postoperative day 3 and were observed within the tubular lumen of renal allograft biopsy specimens on postoperative day 7. After a genetic diagnosis, febuxostat treatment was started on postoperative day 7, with the dosage gradually increased to 80 mg/day until complete the disappearance of 2,8-DHA crystals. Febuxostat prevented secondary 2,8-DHA nephropathy after kidney transplantation.
