Lesinurad with Allopurinol When Allopurinol Alone Is Insufficient

  |  

Current guidelines for the long-term management of gout recommend a combination of lifestyle management and/or pharmacotherapy to lower serum UA levels to <6.0 mg/dL in most patients or <5.0 mg/dL in patients with more severe disease. Allopurinol is the most widely used xanthine oxidase inhibitor and is recommended in treatment guidelines as a first-line urate-lowering…

New Insights into Cartilage & Tendon Differentiation

  |  

By examining the phenotypic plasticity of cartilage and tendon cells, researchers found that oxidative stress and P13K signaling pathways are key modulators of the phenotype of musculoskeletal cells. Using monolayer and three-dimensional cultures, the experiments confirmed that dedifferentiation occurs via reductions in expression of genes for cartilage (Col2a1, Agcn) and tendon (Tnmd, Serpinf1)…

Statin Use Tied to Attenuation of Tocilizumab-Mediated Lipid Increases

Reuters Staff  |  

NEW YORK (Reuters Health)—Statin treatment is associated with an attenuation of the increases in serum lipids experienced by rheumatoid arthritis patients on tocilizumab, according to a post-hoc analysis of clinical trials. Treatment with the interleukin-6 receptor-alpha inhibitor tocilizumab is known to raise total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglyceride levels. To explore the possible effect of…
