Are we putting the CAR-T before the horse?
CAR T-cells have been a revolutionary development in rheumatology. We have seen a population of patients with severe refractory autoimmune conditions almost overnight presented with the prospect of not just improvement, but of a cure.

Psoriatic Arthritis: Which biologic agent is the best first choice?
A growing arsenal of therapeutic targets in psoriatic arthritis (PsA) has enhanced the landscape of treatment in patients with this disease.

In a retrospective study of TAK patients, ~about 1/3 developed new lesions on imaging over time
Most lesions:
- stenotic
- L carotid
- Abdominal aorta
- SMA
50% of the 1/3 = 2 or more lesions
Serial imaging is crucial!

How does DADA2 present?
Ten studies provided data on a total 225 patients
1) skin findings

3) stroke
4) cytopenias

PET and histologic discordance in aortitis
Of 5 aortitis patients who had PET/CT prior to aortic surgery with path, only 1 showed concordance (neg PET, neg biopsy)
4/5 patients had inflammatory biopsy with neg PET
Small # but PET is not perfect!

Delay in PsA diagnosis
Meta Analysis of 32000+ pts
Median diagnostic delay 2.5 years
Median delay in referral 1 year
Increase odds of Rx damage from 50%
Geographic variation
We need to do better

PMR patients need healthcare professionals who know a bit about their disease.
Survey of US HCPs, amongst responders:
- 68% were not aware/unsure about PMR
- of those who were aware, knowledge was… not great (see below)
PMR needs everyone’s respect

A largely understudied area:
Impact of peri-menopause in PsA
Toronto Cohort 473pts, HRT 1.5%
Peri menopause =
increase DAPSA, TJC, SJC, FACIT-fatigue, HAQ
compared to pre- and post-menopause
No association w/ BMI, but with fatigue
Less impact when education level increases https://t.co/bSuGxZCbGn

Abstract 1718: Immune checkpoint inhibitors (ICI) in pre-existing #SLE
Compared to non-SLE pts, those with SLE receiving ICIs had:
🔹 ↑ risk of thrombocytopenia & pancytopenia
🔹 No significant difference in all-cause mortality

IL-5 agents may in fact work for severe EGPA manifestations
Although severe pt were excluded from enrollment in MANDARA, post-hoc and OLE data suggest development of severe manifestations is rare in benra treated patients

The first father-daughter session at ACR?
Brilliant session in diagnostic thinking and mimics in rheumatology from @LCalabreseDO and @CCalabreseDO, teasing apart heuristics, biases, and examples straddling the ID-Rheum divide. Well worth catching on the replay #ACR25 @RheumNow https://t.co/16FEqVyDGg

ANCA status does not inform IL-5 agent response in EGPA patients
Terrier et al. analyzed the OLE of MANDARA and compared ANCA+ and ANCA- subgroups:
- similar rates of remission
- similar rates of GC withdrawal
- comparable relapse rates

Abstract 1657: Can LLMs track medication history?
GPT-4 outperformed most LLMs in identifying TNFi start/stop events and reasons for switch.
💊 Common reasons for TNFi switching: lack of effectiveness, adverse events, and insurance/cost barriers.

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)

Functional MRI studies have been out there for a while, but mechanisms and significance underlying fMRI findings are unclear
fMRI study in 38 active PsA pts w/ significant fatigue
Altered functional connectivity between posterior insula to cerebellum & superior frontal gyrus https://t.co/3s9CJUg2uN

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.
