Why is there female predominance in #SLE - the extra X chromosome in females (XX) may not be inactivated properly- usually maintained by the long non-coding RNA #Xist

Do pts w autoimmune disease (AID) respond differently to immune checkpoint inhibitors (ICI) & have different mortality or iRAE risk vs pts without AID?
Study of pts on ICI showed no significant difference in mortality in pts w & without pre-existing AID

Non-pharm tx in TAK - not something we always think about but…
Impressive effect of resistance exercise!!
Not just in symptoms but also inflammatory markers
Per Dr. Springer - even a stress ball could be enough for UE vascular health in these pt

Lots of data on TYKs including much supporting efficacy in interferon inhibition
Can we really call interferon signalling a "central" pathway in SLE?
Inhibiting it has been modestly successful, at best, and mostly for skin dx

Late-Breaking Abstract L07
The CLASS Project introduces new global classification criteria for Anti-Synthetase Syndrome (ASSD). Using the gold standard dataset, the key findings were:
✅ Definite ASSD: Sensitivity 94.3%, Specificity 99.7%
✅ Probable ASSD: Sensitivity 97.5%,… https://t.co/PtciIMTSsu https://t.co/jvJv2VNvHx

ANA reactive CD4 cells: elevated B cell help activation in SjD
Unique autoreactive T cell cluster in SSc shows CD4+ TRAIL+ IFN type I - unique to SSc
Leads to decrease activation of APCs, decrease CD4 T effector fxn

CRISPR deletion of fibroblasts, gave cytokine activation to mimic inflamm
Are there gene depletions that affect inflamm pathways?
👉SIX1 reduces inflamm potentiation
👉NFIL3 deletion promotes inflamm, degradation

Now we have GWAS, we are getting polygenic risk scores for RA, and we can see what disease risks cluster with RA risk.
RA genetic risk clusters with risk for:
type 1 diabetes
thyroiditis
multiple sclerosis
What draws these diseases together?

The TAPIR study presented at #ACR24 may not be as attention grabbing as others like SELECT-GCA, but in my opinion it is arguablyone of the most important ANCA-vasculitis studies ever. I've shared some further thoughs in an article on @RheumNow https://t.co/mImAE8ezSQ
