BACKGROUND To study the prevalence of chronic kidney disease (CKD) and its impact on allopurinol dosing and uric acid control among patients with gout. METHODS This was a retrospective study using data from a large US health plan. Claims and laboratory data were analyzed for enrollees from the health plan database from January 2002 through December 2005. Patients with gout were identified fro...

INTRODUCTION To assess the comparative effectiveness of febuxostat and allopurinol in reducing serum urate (sUA) levels in a real-world U.S. managed care setting. METHODS This retrospective study utilized 2009 to 2012 medical and pharmacy claims and laboratory data from a large U.S. commercial and Medicare Advantage health plan. Study patients had at least one medical claim with a diagnosis o...

AIMS To characterize patients with urate measurements by urate-lowering therapy (ULT) use and to study the impact of allopurinol treatment on cardiovascular and mortality outcomes. METHODS A cohort study using a record-linkage database. The study included 7135 patients aged ≥60 years with urate measurements between 2000 and 2002 followed up until 2007. A Cox regression model was used. The ass...

This study was performed to assess the effect of allopurinol in a canine preparation of myocardial infarction. Dogs underwent occlusion of the left circumflex coronary artery for 90 min, followed by reperfusion for 6 hr. Three groups were studied: (1) control, (2) dogs receiving 25 mg/kg allopurinol 18 hr before occlusion and 50 mg/kg 5 min before occlusion, and (3) dogs receiving allopurinol a...

Allopurinol ameliorates endothelial dysfunction and arterial stiffness among patients without chronic kidney disease (CKD), but it is unknown if it has similar effects among patients with CKD. Furthermore, because arterial stiffness increases left ventricular afterload, any allopurinol-induced improvement in arterial compliance might also regress left ventricular hypertrophy (LVH). We conducted...

INTRODUCTION Diabetic nephropathy is the most prevalent cause of end-stage renal disease. Besides factors such as angiotensin II, cytokines, and vascular endothelial growth factor, uric acid may play a role as the underlying cause of diabetic nephropathy. We evaluated allopurinol effects on proteinuria in diabetic patients with nephropathy. MATERIALS AND METHODS In a double-blinded randomized...

BACKGROUND Several studies have tested the effects of allopurinol on arterial stiffness, but the results have been inconclusive. We aimed to conduct a meta-analysis to investigate the impacts of allopurinol treatment on arterial stiffness, as measured by pulse wave velocity (PWV) and augmentation index (AIx). MATERIAL AND METHODS Randomized controlled trials (RCTs) assessing the effects of allo...

The presence of Trypanosoma cruzi in chronic chagasic patients with negative xenodiagnosis (XD) after 6 years following completion of therapy with either itraconazole or allopurinol was assessed by polymerase chain reaction (PCR) and hybridization assays. A 330-bp DNA fragment amplified from the hypervariable regions of T. cruzi kinetoplastid minicircles was hybridized with total 32P-labeled ki...

Allopurinol, a competitive inhibitor of xanthine oxidase, has been shown to have a protective effect on ischemic myocardium, but its mechanism of action remains controversial. We used an isolated rat heart preparation to test the hypothesis that allopurinol could restore adenosine triphosphate (ATP) levels and improve the recovery of left ventricular function after global myocardial ischemia. H...
