Objective.: To test the performance of the 2015 ACR-EULAR gout classification criteria against presence of SF MSU crystals in a primary healthcare population. Methods.: The criteria were applied to an existing dataset of consecutive patients with monoarthritis presenting to Dutch family physicians; all patients underwent microscopic SF analysis by design. The data had been prospectively collected to develop a diagnostic decision rule for gout in 2010. Diagnostic performance was assessed by calculating area under the receiver operating characteristic curve, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and constructing calibration plots for the full version of the criteria (including SF analysis results of all patients) and the clinical-only version (not including SF analysis results)...

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)...

In the past few years, metastatic renal cell carcinoma prognosis was improved by the development of molecular targeted therapies (TTs). At the metastatic stage, the tolerance to treatment is a major concern, not only because of the challenge of the efficacy/toxicity ratio improvement but also because of the importance of an optimal adherence to oral treatments. The present case series relates the issues of dealing with uncommon and sometimes never described side effects of sunitinib and sorafenib. The first case report deals with grade 3 vomiting during hemodialysis with concurrent administration of sunitinib...

Ganapathy Sivakumar
The plant-based colchicine potentially affects major diseases such as cardiovascular events, cancers and gout. Gloriosa superba seeds are a conventional pharmaceutical source of colchicine. The demand for pharmaceutical-grade colchicine has increased due to the shortage of feasible upstream manufacturing, encompassing all stages in the processes of biosynthesis and biomanufacturing before the raw material is ready for purification. Consequently, developing sustainable upstream industrial colchicine biofactories is imperative, especially in curtailing drug costs...

BACKGROUND: Clinical observations indicated an increased risk of developing prostate cancer in gout patients. Chronic inflammation is postulated to be one crucial mechanism for prostate carcinogenesis. Allopurinol, a widely used antigout agent, possesses potent anti-inflammation capacity. We elucidated whether allopurinol decreases the risk of prostate cancer in gout patients. METHODS: We analyzed data retrieved from Taiwan National Health Insurance Database between January 2000 and December 2012...

Objective.: Gout is characterized by recurrent attacks of arthritis with hyperuricaemia and urate crystal-induced inflammation. Although urate transporters are known as risk factors, the immunogenetics of gouty inflammation remains unclear. This study aimed to investigate the genetic association between immune/metabolism regulators and gout. Methods.: We enrolled 448 gout patients and 943 population controls from Taiwan; all were Han Chinese. We screened association between gout and 22 variants of candidate genes, including NLRP3 , caspase 1, peroxisome proliferator-activated receptor-γ, proliferator-activated receptor-γ coactivator 1α ( PPARGC1A ) and 1β ( PPARGC1B )...
