febuxostat in renal transplant

Hyun Seon Kim, Sun Woo Lim, Long Jin, Jian Jin, Byung Ha Chung, Chul Woo Yang
BACKGROUND: The use of calcineurin inhibitors is a well-known risk factor for hyperuricemia in kidney transplant recipients. We evaluated the effect of febuxostat (Fx), a new uric acid-lowering drug, on hyperuricemia and renal injury in an experimental model of chronic tacrolimus (Tac)-induced nephropathy. METHODS: Chronic Tac nephropathy was induced by administering Tac (1.5 mg/kg/day) to rats on a low-salt diet (0.05%) with oxonic acid (OA, 2%, 0.2 g/kg/day) for 28 days...

Febuxostat is a non-purine, selective inhibitor of both isoforms of xanthine oxido-reductase (XOR), and a major alternative to the scarce number of urate-lowering medications available in the last decades. Its inhibition of XOR is more potent than allopurinol in a mg to mg comparison, what is associated to achievement of serum urate target more frequently than allopurinol at doses tested in clinical trials, especially in patients with the highest baseline serum urate levels. Its pharmacokinetics is not greatly dependent on renal clearance, contrary to allopurinol, what may be an advantage in patients with chronic kidney disease...

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...

BACKGROUND: Post-transplant hyperuricemia (PTHU), defined as serum uric acid concentration ≥7.0 mg/dL or need for treatment with allopurinol or benzbromarone, reduces long-term allograft survival in kidney transplant recipients. Febuxostat, a new nonpurine selective xanthine oxidase inhibitor, is well tolerated in patients with moderate renal impairment. However, its efficacy and safety in kidney recipients with PTHU is unclear. We therefore assessed the efficacy and safety of febuxostat in stable kidney transplant recipients with PTHU...

INTRODUCTION: The shortage of cadaver organs has led to expansion of living donor kidney transplantations with, 30% increase among ABO-incompatible cases in Japan and the use of marginal extended donors. Herein we have reported the outcome after an ABO-incompatible kidney transplantation from an aged living-related donor who suffered from mild diabetes mellitus and hypertension. CASE REPORT: A 48-year-old man underwent ABO-incompatible kidney transplantation from his 76-year-old father, using anti-CD20 antibody induction, followed by cyclosporine (CsA), mycophenolate mofetil (MMF), and prednisolone...

Hyperuricemia and gout are common among adult renal transplant recipients, but it is rarely reported following pediatric renal transplantations. Treating gout in pediatric kidney transplant recipients presents clinical challenges to the management of both immunosuppressive regimen and hyperuricemia for their effects on serum uric acid levels, renal function and drug interactions. Most renal transplant recipients have a relative impairment of renal clearance of urate due to abnormalities in renal transport, explaining the association of hyperuricemia and decreased glomerular filtration rate...

The aim of urate-lowering therapy is to maintain urate concentration below the saturation point for monosodium urate. This therapy dissolves crystal deposits and cures gout while it is maintained. EULAR guidelines recommend that plasma urate should be maintained at a concentration less than 360μM, and the British Guidelines less than 300μM. Urate-lowering therapy is indicated for patients with recurrent gout attacks, chronic arthropathy, tophi, and gout with uric acid stones. Allopurinol lowers uricemia through inhibition of xanthine oxidase activity...

INTRODUCTION: Gout is a common and disabling cause of arthritis in middle-aged and elderly populations, with its main predisposing factor being hyperuricemia (serum urate > 6.8 mg/dL). Options for treatment of chronic gout until 2008 were allopurinol, a xanthine oxidase inhibitor, and the group of drugs known as uricosurics that stimulate the renal excretion of uric acid. A proportion of patients, including some with chronic kidney disease and solid organ transplantations, could not be treated with the those therapies because of intolerance, drug interactions, or adverse events...
