Does adding a Clofutriben (HSD-1 inhibitor) w/ prednisone minimize the risks of steroid toxicities in #PMR patients?
VS placebo, PMR patients who received Clofutriben + Prednisone had substantial reductions in bone, lipid, and glycemic control parameters

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

Does vasculitis flare with checkpoint inhibitors?
@MDAndersonNews experience:
17 stable pts
4 pts flared - all able to be controlled
(i.e. 13 didn't flare)
Encouragement that stable vasculitis pts that need ICI should get them!

Dr. @karen_kc123 discusses the results of the VITAL study.
- Long term use of Vit D3 2000IU was safe and decreased the incidence of all autoimmune dses by 22%.
- It took a while to work but the effect dissipates once discontinued.

Will be covering some TAK pearls and pitfalls from today’s session!
Renal dz stratified by location of vessel inflammation:
- TAK = proximal (off aorta)
- FMD = mid-section, beading
- PAN = distal arterial branches

A call for ANA stewardship?
Abstract 1931: Educating clinicians on wise ANA ordering via EMR Alert plus removing the comprehensive ANA panel -->
- ↓ ANA testing (outpatient 15.9%→7.4%, inpatient 25.5%→6.4%)
↓ costs ($440k→$130k)

Study of 25K+ patients using TrinetX on immune checkpoint inhibitors shows no significant mortality difference between those with pre-existing autoimmune disease (AID) and those without.
Mortality rates:
AID: 39.8%
Non-AID: 40.2%
Large-scale evidence supports ICIs in AID… https://t.co/BI5jK9jsoM

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

Imaging in TAK Diagnosis
@KQuinnRheum @RheumNow
⭐ Take homes ⭐
👉location of renal artery stenosis (RAS) key to making Dx with proximal RAS in TAK
👉FDG PET -focal uptake in TAK vs diffuse in GCA
👉MRI good surrogate for disease activity where PET unavailable

Mental health, sex, and comorbidities are key factors in determining recalcitrant psoriatic arthritis (PsA).
Key findings:
- 21.7% of patients required ≥4 biologic/targeted synthetic DMARDs.
- Female patients and those with depression were more likely to be recalcitrant.
- No… https://t.co/I9YYoRnLwh https://t.co/VtnPceVLOZ
