OBJECTIVES Determine the efficacy and safety of daily lesinurad (200 or 400 mg orally) added to allopurinol in patients with serum uric acid (sUA) above target in a 12-month, randomised, phase III trial. METHODS Patients on allopurinol ≥300 mg (≥200 mg in moderate renal impairment) had sUA level of ≥6.5 mg/dL (≥387 µmol/L) at screening and two or more gout flares in the prior year. Primary en...

Allopurinol is the mainstay of urate-lowering therapy for patients with gout and impaired renal function. Although rare, a life-threatening hypersensitivity syndrome may occur with this drug. The risk of this allopurinol hypersensitivity syndrome (AHS) is increased in renal impairment. The recognition that AHS may be because of delayed-type hypersensitivity to oxypurinol, the main metabolite of...

Gout can have a significant impact on the quality of life (QoL) patients. Objective: to assess dynamics QoL indicators and possibility achieving target level uric acid (UA) in patients with gout febuxostat therapy, ineffectiveness / or contraindications allopurinol administration. Patients methods. The prospective, single-center study included 80 gout. follow-up period was at least 6 months (Az...

Background Thiopurines, azathioprine (AZA) and 6-mercaptopurine (6-MP) are common maintenance medications for inflammatory bowel disease (IBD). Excessive methylation via thiopurine methyltransferase (TPMT) frequently causes therapeutic failure. Allopurinol reduces excessive 6-methyl-mercaptopurine (6-MMP) while enhancing 6-thioguanine (6-TGN) levels. The aim of this study was to evaluate clinic...

CONTEXT Despite multiple trials of different adjuvant therapies to an antipsychotic regimen, there have been few promising results. Allopurinol may be one promising adjunctive therapy based on three randomized controlled trials. OBJECTIVE To determine whether adjuvant allopurinol would be beneficial to a patient already on multiple trials of antipsychotics with no improvement. RESULTS Allop...

INTRODUCTION Previous studies have shown an association between gout and/or hyperuricemia and a subsequent increase in cardiovascular disease (CVD) outcomes. Allopurinol reduces vascular oxidative stress, ameliorates inflammatory state, improves endothelial function, and prevents atherosclerosis progression. Accordingly, we tested the hypothesis that a positive association between allopurinol t...

BACKGROUND Hyperuricemia has been associated with the development of high blood pressure (BP). We studied the effects of allopurinol therapy in hyperuricemic hemodialysis (HD) patients with high BP. MATERIALS AND METHODS This single-blind, randomized cross-over clinical study involved 55 HD patients with serum uric acid level > 6.5 (men) and > 5.5 mg/dL (women). They were randomly divided in ...
