Dr. Jack Cush reviews the regulatory actions, news and journal reports from this past week on RheumNow.com.

1. FDA Approves Icotrokinra for Plaque Psoriasis
2. FDA has approved secukinumab (Cosentyx) for use pediatric patients (aged >12yrs) with moderate to severe hidradenitis suppurativa
3. https://t.co/G1BtS15sWT
4. FDA has accepted the supplemental biologics license application for use of interleukin-23 inhibitor tildrakizumab (Ilumya; Sun Pharma) in active psoriatic arthritis (PsA) in adults. https://t.co/cwqz9DoWsL
5. Urinary biomarkers improve w/ anifrolumab in TULIP-LN (lupus nephritis) trial; 112 pts, 197 uriniary proteins assessed. Urinary CD163 and MCP-1 signif improved as early as wk 12. Anifrolumab reduced the proteomic inflammatory signature, regardless of responder status https://t.co/n6fIJVDCN1
6. REVEAL, a 5-yr real-world study of 236 SLE pts initiating anifrolumab (basekbube SLEDAI-2K 7 for mucocutaneous (67%) & MSK (49%) dz. At 6 months, 26% achieved remission, 66% reached LLDAS, and 57% achieved LLDAS5. Authors claim rapid onset of action https://t.co/16OQatOcPj
7. SOLSTICE: phase 3b RCT of IL-23i, guselkumab vs PBO in 451 active PsA pts (GUS q4wk vs q8wk vs PBO). @wk 24 GUS signif better than PBO-ACR20 (59%/62% vs 35%), ACR50 (31%/32% vs 12%), ACR70 (17%/17% vs 2%), PASI 90 (49%/45% vs 12%), MDA (19%/24% vs 5%) https://t.co/QDMCnGdN6J
8. Pilot phase I open-label trial of the PPARγ agonist pioglitazone (ACTOS; 45 mg/d) in 13 pts w/ inclusion body myositis (IBM) showed promise. After 32 weeks, no clinical improvement but proteomic muscle metabalomics & PPARGC1A expression improved. https://t.co/MtiTnwRfaE https://t.co/jUthouMSnP
9. JAMA Patient Education Page on JAMA Eosinophilic Fasciitis (EF). EF is rare, but begins with swelling and redness of the arms and/or legs. Later the skin thickens and develops the peau d’ orange appearance. EF does not involve fingers or toes, & doesnt have Raynauds https://t.co/azH9bMRsOb
10. Single center prospective cohort study of 137 Takayasu’s arteritis (TAK) pts found the prevalence of coronary arteritis was 13 (9%). TAK coronary arteritis pts were not distinguished by demographics, angiographic patterns. 50% had complications from vascular grafts or stents https://t.co/xRR7TSi5FW
11. Hydralazine and the Rare Risk of Vasculitis Since the 1980s, hydralazine has been a notable cause of drug-induced lupus, and inferred to cause vasculitis as well. A retrospective cohort study from Canada has shown that vasculitis resulting from hydralazine is possible, but rare, inconsequential. https://t.co/ewqCesatbm
12. Cross-sectional study of 180 PMR pts compared dz activity by PMR-AS to Systemic Immune-Inflammation Index (SII = Plts × PMNs/Lymphs) using CBC.48% had mod-hi dz (PMR-AS >=7). SII had moderate correlation with PMR-AS (r = 0.47), possibly useful in monitoring PMR https://t.co/vG1alSdVRU
13. A multi-center, retrospective chart review of 82 Still’s disease pts (63% female; mean Dx age 6.4 ± 4 yrs; F/U ~2.8 yrs). When analyzing Dz course, 34% were monophasic, 46% polyphasic (higher-than-expected), 19.5% persistent Dz. non-monophasic predicted by active 3 mos from Dx https://t.co/qtONtpeA22
14. Rheumatic Immune-related Adverse Effects with Checkpoint Inhibitor Therapy A retrospective study of patients who developed rheumatic immune-related adverse events (R-irAEs) after receiving immune checkpoint inhibitors (ICIs) at two oncology centers in Spain suggests that early recognition is important https://t.co/hYf6GiR6TN
15. Worldwide Trends in Hyperuricemia
16. Pitfalls of autoimmune serologic testing
