Hospitalization in Stills: Is it "Still" an infection?
Dr. Janet Pope discusses abstract 0163, "Trends in hospitalization and outcomes among patients admitted with Adult-onset Still’s disease in the United States: INSIGHTS FROM THE NATIONAL INPATIENT SAMPLE (2016-2022)," https://t.co/3Z0U9XN3nx

@CarolineDiorio @ChildrensPhila @RheumNow Indeed, there are a lot of familiar HLH/MAS friends in the post-CAR-T CRS mix...
(indeed, rheum friends from many places)

I've always (very) simplistically considered post-CAR-T CRS and HLH/MAS in the same bucket, and there certainly are substantial similarities.
It raises the obvious question - can we borrow therapies?

What dictates how severe CRS is following CAR-T?
(Often the critical question, and will especially be in the autoimmune space, where CAR-T is largely less time-critical)

CAR-T Cell Therapies Show Promise for Autoimmune Disease
Two pioneering studies presented at #ACR25 spotlight the potential of CAR-T cell therapies to transform treatment for SLE and other autoimmune diseases. These early findings suggest a new frontier in immune modulation and https://t.co/KdNWmVc4Qc

The next VEXAS, but also maybe we can treat it?
IDH1/2
Another clonal hematopoesis known to cause heme malignancy, but also some inflamm sequelae (autoinflamm-like e.g. PMR/GCA)
& you can directly inhibit it
Wow. We will hear more

#ACR25 Abstr#LB21 Are they novel somatic variants beyond #VEXAS in driving inflammation in undiagnosed SAID?Unbiased enrichment analysis in 265 UBA1-negative adults identified IDH1/2 hotspot mutations. Cd be used to screen esp those with cytopenia. Sorry pix not allowed @RheumNow

The Power of Gamma Delta T Cell for Autoimmunity https://t.co/wIMu5r7b3D
More on T Cell engagers , this time with gama delta T cell ( tiny but mighty ). Kate Roslin talks about advantages of this protocol. (No cytokines thus less toxicity).

How does DADA2 present?
Ten studies provided data on a total 225 patients
1) skin findings
2) fever
3) stroke
4) cytopenias

When MAS is suspected. Soluble IL2 receptor alpha and CXCL9 may be useful (however t cell lymphomas and viral infections like hepatitis may also have them)
#ACR25 @RheumNow
Key takeaways below https://t.co/wJv1dvwU88

Soluble IL2 receptors help assess macrophages behavior. Ferritin also asses the same in Macrophage activation syndrome.
ADA2 is the newer biomarker for hemophagocytic syndromes.
#ACR25 @RheumNow
Interferon gamma also a newer important target in MAS https://t.co/7sWwninBTM

Simultaneous measurements if S100, Ferritin and IL-18 increase diagnostic utility of these biomarkers in Stills disease.
@RheumNow #Acr25 https://t.co/3wmijNcpVY

Low percentage of glycosylated Ferritin was more specific for Stills disease but not used frequently in clinical practice.

Biomarkers in Stills disease and MAS. #ACR25 @RheumNow
IL 6 may not be helpful compared to CRP, and IL 1 beta is difficult to measure
IL-18 seems to be the best one. https://t.co/u3oBTd4eaP
Bella Mehta bella_mehta ( View Tweet)
IL- 18 go together sometimes with glycolytic enzymes such as aldolase
Also MAS may not be a switch on and off mechanism.
Lastly MAS with Stills may have increased IL18 levels but not in other disease like SLE
#ACR25 @RheumNow https://t.co/BW1fD7usBT
Bella Mehta bella_mehta ( View Tweet)
What do we know about IL-18
Normal levels less than 500
Non specific 500 to 15000
Stills (quiet) 2000 to 10000
Mas/glares 20000 and more

AOSD And sJIA aren't the same disease!!!. Another take on this by Scott Canna..because the clinical syndrome might have somethings distinct!!

#0777 Big news for VEXAS! 🎯
The first validated disease activity index (VEXAS-DAI) has been developed via international Delphi consensus. A 12-domain, 40-point tool to standardise assessment & power trials in this complex syndrome. Validation underway! @RheumNow #ACR25 https://t.co/DSeHb7eNeV
