JAK/TYK2

The big news this week: the approval of deucravacitinib (a new class of drug?) for psoriasis; the 2022 ACR guidance on glucocorticoid-induced osteoporosis; a national poll of older adults over the age of 50 who claimed self-reported or doctor-diagnosed arthritis; and much more. Let's review these and other news, journal reports and announcements from this past week.

Deucravacitinib (Sotyktu), a first-in-class, oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor, is the only approved TYK2 inhibitor worldwide and the first innovation in oral treatment for moderate-to-severe plaque psoriasis in nearly 10 years.

Can we predict the bad outcomes? Like when ITP evolves into SLE; or when psoriasis will develop arthritis; or if Sjogren's will develop lymphoma? Let's dive in and review these journal reports and this past week's news from RheumNow.com.

Research presented in the Journal of Experimental Medicine shows that ANCA-associated vasculitis (AAV) may be propagated by pathogenic mechanisms triggering cGAS/STING/IRF3-dependent IFN-I release.

Dr. Jack Cush reviews the news and journal reports from this past week on RheumNow and discusses a case of refractory juvenile dermatomyositis with calcinosis.

We've got a lot to discuss this week: psoriasis; fatigue; sleep; sural nerve biopsies; uveitis and SpA; diet and RA; tofacitinib and the ORAL surveillance study; what not to take with mycophenolate - and more. In what order should these items be discussed? This week the run down is based on popularity, measured by rheumatologist engagements on the website and social media.

Another analysis of the mandatory postmarketing safety study for tofacitinib (Xeljanz) has confirmed what most observers expected: that rates of infection with the drug in rheumatoid arthritis are higher than with tumor necrosis factor (TNF) inhibitors.

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.

Dr. Jack Cush reviews the news, FDA approvals, journal articles from the past week on RheumNow; plus viewer questions. This week great hopes for vitamin D, the great unknows of CSA and the great big mess that is the gout.

The ACR has posted a new ACR Clinical Practice Guideline Summary providing recommendations on the use of vaccinations for children and adults with rheumatic and musculoskeletal diseases (RMDs). This guideline builds on past ACR vaccination guidance, last published in 2021.

Tan and Buch have reviewed the approach to difficult to treat rheumatoid arthritis (D2T-RA), with a new EULAR definiation of D2T-RA to foster an approach rationale and concideration of treatment options.

Are you treating “systemic” or “articular” (arthritis) Still’s disease? Most Still’s patients have a dominance of one or the other. With certainty, the right therapy for the right symptoms can be chosen. What about patients who have an incomplete or no response, or who become unresponsive to a drug that once worked well?

Dr. Jack Cush covers the news and journal reports from the past week on RheumNow.com. This week we have Insights NAFLD, overdose deaths, septic arthritis, refractory stills, & when MTX doesn’t work.

A large prospective psoriatic arthritis (PsA) study examined the enthesitis outcomes when PsA patients received conventional (cDMARDs) or targeted disease-modifying antirheumatic drugs (tDMARDs) and showed an overall 86% response rates, regardless of the medication used.

With the recent publication of the third iteration of the GRAPPA Psoriatic Arthritis (PsA) treatment recommendations, it seems to be an auspicious time to reflect on some key considerations that arose during the development of the recommendations, as well as to look towards what the future may hold.
