Drug Safety

      A population-based study from Ontario, Canada suggests an increased mortality risk in patients with giant cell arteritis (GCA), according to a recent report in Arthritis Care & Research. A health administrative data study looked at 22,677 GCA patients (≥50 years of age) compared to an age matched population for mortality rates between 2000 and 2018. Standardized mortality ratios (SMRs) were estimated.

      A small retrospective study suggests that patients with difficult to treat adult-onset Still's disease (AOSD) or sytemic juvenile idiopathic arthritis (sJIA) may respond well to JAK inhibitor (JAKi) agents - presumable by blocking pro-inflammatory cytokines, notably IL-6 and IFN.

      Oral surveillance - tofacitinib vs TNFi in high risk pts: more infections, serious infection (SIEs) & non-serious infx with Tofa vs TNFi. SIE risk 17%-48% higher; SIE higher w/ high dose Tofa, esp in pts aged≥65. Usual risk factors - age, pred, comorbid. https://t.co/gjD8xqtfgp https://t.co/doMd4E9ClL

      A large case-control study showed that gout patients who experienced a cardiovascular (CV) event were more likely to have had a recent (< 120 days) gout flare compared to those without CV events. This study sought to investigate the temporal association between gout flares and cardiovascular events in a gout cohort.

      Krill oil supplements in knee osteoarthritis (OA) was shown to be superior to placebo in reducing knee pain, stiffness and function while increasing the omega-3 index. Krill oil, rich in anti-inflammatory long-chain (LC) omega-3 ( ω–3) PUFAs and astaxanthin, is thought to be safe and now shown to be effective nutritional treatment for mild to moderate knee OA.
      The janus kinase inhibitor, upadacitinib, has been shown to significantly improve the signs and symptoms of non-radiographic axial spondyloarthritis (nr-AxSpA), extending the efficacy of UPA beyond classic ankylosing spondylitis.
