The European League Against Rheumatism published updated recommendations for the management of gout in 2016, comprising 3 overarching principles and 11 key recommendations for clinical practice. Patient education about the pathophysiology of gout and its comorbidities, as well as the existence of effective treatments are important, and understanding the principles of managing acute attacks and eliminating urate crystals by lifelong lowering of the serum urate (SU) below a target level are essential. Advice about lifestyle, diet, weight, and other risk factors, as well as the need to screen for, and manage, comorbidities is emphasized...

Emma D Deeks
Lesinurad (Zurampic(®)) is an oral selective inhibitor of the URAT1 and OAT4 uric acid (UA) transporters of the kidney, via which it inhibits UA reabsorption and thus increases renal UA excretion and lowers serum UA (sUA) levels. Lesinurad 200 mg once daily is indicated for use in combination with a xanthine oxidase inhibitor (XOI) to treat hyperuricaemia in adults with gout who have not achieved target sUA levels with an XOI alone. Approval was based on three 12-month phase 3 trials that evaluated lesinurad in combination with allopurinol in adults with gout inadequately responsive to allopurinol (CLEAR 1 and 2) and in combination with febuxostat in adults with tophaceous gout (CRYSTAL)...

Higher plasma uric acid (PUA) levels are associated with lower GFR and higher blood pressure (BP) in patients with type 1 diabetes (T1D). Our aim was to determine the impact of PUA lowering on renal and vascular function in patients with uncomplicated T1D.T1D patients (n=49) were studied under eu- and hyperglycemic conditions at baseline and after PUA lowering with febuxostat (FBX) for 8 weeks. Healthy controls (HC) were studied under normoglycemic conditions (n=24). PUA, GFR (inulin), effective renal plasma flow (ERPF, paraaminohippurate), BP and hemodynamic responses to an infusion of angiotensin II (assessment of intrarenal RAAS) were measured pre- and post-FBX...

OBJECTIVE: Patients with an HLA-B*58:01 allele have an increased risk of developing severe cutaneous adverse drug reactions (SCAR) when treated with allopurinol. Although one-off pharmacogenetic testing may prevent life-threatening adverse drug reactions, testing prior to allopurinol initiation incurs additional costs. The study objective was to evaluate the cost-effectiveness of HLA-B*58:01 screening compared with using other available urate-lowering agents (ULA). METHODS: A decision-analytical model was used to compare direct medical costs and effectiveness [including lifetime saved, quality-adjusted life-yrs (QALY) gained] in treating new patients with the following options: (1) genetic screening followed by allopurinol prescribing for noncarriers of HLAB* 58:01, (2) prescribing benzbromarone without screening, (3) prescribing febuxostat without screening, and (4) prescribing allopurinol without screening...

BACKGROUND: This case report describes a spontaneous tumor lysis syndrome due to a rare solid tumor. CASE PRESENTATION: A 65-year-old white woman had tumor lysis syndrome, which represent a dangerous oncological emergency. This syndrome occurs usually with a hematological tumor, but in this case our patient had a solid tumor, which was a rare extraskeletal osteosarcoma, localized in her pelvic region. She also had lung metastases and bilateral hydronephrosis. After spontaneous tumor lysis syndrome, she had acute renal insufficiency, which was treated with hemodialysis and successively with rasburicase, Kayexalate (sodium polystyrene sulfonate), and febuxostat...

Xanthine oxidase is a key enzyme responsible for hyperuricemia, a pre-disposing factor for Gout and oxidative stress-related diseases. Only two clinically approved xanthine oxidase inhibitors Allopurinol and Febuxostat are currently used for treatment of hyperuricemia. However, owing to their side effects there is a need for new non-purine-based selective inhibitors of xanthine oxidase. In the process of exploring novel xanthine oxidase inhibitors and anti-oxidants, we screened the culture filtrate of 07 novel species of Muscodor, a sterile endophytic fungi isolated from Cinnamomum and Aegle marmelos...

Sildenafil and febuxostat protect against doxorubicin-induced nephrotoxicity; however the exact mechanism remains to be elucidated. The effect of sildenafil and febuxostat on doxorubicin-induced nephrotoxicity in rats was studied. Male rats were subdivided into nine groups. The 1(st) group served as normal control, the 2(nd) group received dimethylsulfoxide 50% (DMSO), the 3(rd) group received doxorubicin (3.5mg/kg, i.p.), twice weekly for 3 weeks. The next 3 groups received sildenafil (5mg/kg; p.o.), febuxostat (10mg/kg; p...

Gout is the most common cause of inflammatory arthritis worldwide. Despite clinical cure being achievable and multiple evidence-based guidelines having been published, the incidence and prevalence continues to increase and the condition remains undertreated. Concerns regarding allopurinol have limited its use in those with renal impairment. Febuxostat, a novel xanthine oxidase inhibitor requiring no dose adjustment in mild-moderate renal impairment was launched in the United Kingdom (UK) in 2010. We review published data on the efficacy, safety and tolerability of febuxostat and provide an opinion on its place in the management of gout in the UK in the context of other published guidelines...

The treatment of gout is based on several principles. Symptom control and termination of the inflammatory process are important early goals, whereas the urate level should be lowered in the long term to prevent further gout attacks and complications. The non-pharmacological approach is based on individually informing the patient on dietary measures and changes of life style. Besides physical measures, such as cold applications on the affected joint, various medications are available for treatment of an acute gout attack...

Several studies suggest that chronic hyperuricemia, the main precursor of gout, is involved in the pathogenesis of different systemic disorders that affect cardiovascular and renal systems, such as hypertension, obesity, hypercholesterolemia, atherosclerosis, metabolic syndrome, chronic heart failure, and chronic kidney disease. Recent epidemiological evidence has shown an increasing trend in the prevalence of hyperuricemia and gout in the Western world: a number of population-based studies estimate a prevalence of up to 21% for hyperuricemia and 1%-4% for gout...

Febuxostat exhibits unprecedented solid forms with a total of 40 polymorphs and pseudopolymorphs reported. Polymorphs differ in molecular arrangement and conformation, intermolecular interactions, and various physicochemical properties, including mechanical properties. Febuxostat Form Q (FXT Q) and Form H1 (FXT H1) were investigated for crystal structure, nanomechanical parameters, and bulk deformation behavior. FXT Q showed greater compressibility, densification, and plastic deformation as compared to FXT H1 at a given compaction pressure...

Gout is the most prevalent inflammatory arthritis and affects 2.5% of the general population in the UK. It is also the only arthritis that has the potential to be cured with safe, inexpensive and well tolerated urate-lowering treatments, which reduce serum uric acid by either inhibiting xanthine oxidase - eg allopurinol, febuxostat - or by increasing the renal excretion of uric acid. Of these, xanthine oxidase inhibitors are used first line and are effective in 'curing' gout in the vast majority of patients...

The new chemical entities febuxostat and topiroxostat have been approved by the US Food and Drug Administration, opening new avenues for exploiting different heterocycles other than purines as xanthine oxidase (XO) inhibitors. A different series of substituted 2-benzamido-4-methylthiazole-5-carboxylic acid derivatives (5a-r) was synthesized and characterized by the collective use of IR, (1) H and (13) C NMR, and mass spectroscopy, for the treatment of gout and hyperuricemia. In vitro studies of the synthesized derivatives revealed that the presence of a fluoro group at the para position in 5b (IC50 = 0...

The pharmacokinetics (PKs) of febuxostat varies among individuals, while the main causes are still unknown. We investigated whether the polymorphisms of UGT1A1 and UGT1A3 played an important role in the disposition of the drug after oral administration of febuxostat tablet in Chinese subjects. A total of 42 healthy subjects were from two previous independent clinical bioequivalence (BE) trials of febuxostat, in which the same reference formulation (ULORIC(®) tablet, 80 mg) was taken, and thus the PK data were combined for the evaluation of pharmacogenomic effect on febuxostat PKs...

BACKGROUND: Hyperuricemia is a common adverse event frequently found in renal transplant recipients with mizoribine (MZ). Hyperuricemia itself will be a cause of renal dysfunction, and renal dysfunction also will be a cause of hyperuricemia simultaneously. This study investigates frequency of hyperuricemia and renal failure in renal transplant recipients treated with high-dose MZ. PATIENTS AND METHODS: From December 2007 to October 2015, there was a total of 32 living related renal transplant recipients treated with high-dose MZ...
