ABSTRACT

BACKGROUND: Febuxostat, a novel nonpurine selective inhibitor of xanthine oxidase, is a potential alternative to allopurinol for patients with hyperuricemia. In this study, we evaluated the efficacy and safety of febuxostat for the management of hyperuricemia in renal transplant recipients. PATIENTS AND METHODS: Between June 2012 and January 2013, a total of 22 renal transplant recipients (56 ± 10 years old) with hyperuricemia were enrolled in this study. All patients underwent de novo kidney transplantation, except for 1 patient, who received a second kidney transplant. Ten patients receiving allopurinol and 3 patients receiving benzbromarone were converted to febuxostat at doses of 10-20 mg/d. In the remaining 9 patients, who did not have a history of other urate-lowering medications, febuxostat was initiated at a dose of 10 mg/d. RESULTS: Uric acid levels after initiation of febuxostat were significantly lower than before treatment (5.7 ± 0.7 mg/mL vs 8.0 ± 0.8 mg/mL; P < .001). At last follow-up visit, 16 of the 22 patients (73%) achieved uric acid levels of ≤ 6.0 mg/dL, despite the low dosage of febuxostat. All patients were maintained on febuxostat without serious adverse events, except for 1 patient, who discontinued febuxostat because of numbness in the arms. CONCLUSIONS: Low-dose febuxostat is a promising alternative to allopurinol or benzbromarone for the treatment of hyperuricemia in kidney transplant recipients. The long-term urate-lowering efficacy and safety of febuxostat with regard to renal function in kidney transplant recipients with hyperuricemia requires further investigation.

ABSTRACT

OBJECTIVE: We perform living-related ABO-incompatible kidney transplantations to alleviate the organ shortage in our country. Splenectomy has been performed routinely in these recipients, although its clinical significance remains controversial. In this study, we have reported our experience with a hand-assisted laparoscopic splenectomy (HALS) technique. METHODS: Between April 2000 and December 2006, 50 patients (23 males) underwent ABO-incompatible kidney transplantation with HALS. The mean age and weight of the recipients were 44 +/- 13 years and 56 +/- 12 kg, respectively. All patients underwent preoperative plasmapheresis to reduce isoagglutinin (A and/or B antibody). In 6/50 patients, a hand-assisted device was placed through a peritoneal window in the right lower abdominal skin incision for kidney engraftment. In the remaining 44 patients, a 6-cm upper midline or periumbilical midline incision was made for the hand-assisted device in the lateral position. RESULTS: An ABO-incompatible procedure was completed successfully in all cases. The average HALS time was 118 +/- 42 minutes, with an average pneumoperitoneum time of 79 +/- 40 minutes and average blood loss of 48 +/- 81 g. There were two conversions to open splenectomy because of intraoperative bleeding and suspected pneumothorax. Two other cases required relaparotomy because of hematoma and perforation of the ileum. Successfully operations were achieved through the previous periumbilical incision. CONCLUSIONS: Although meticulous, rigorous surgical technique is essential, HALS is safe and feasible for recipients of ABO-incompatible grafts with tissue weakness and a bleeding tendency because of renal failure and preoperative plasmapheresis.
