Identifying Gaps in axSpA: Lessons from European Map of Axial Spondyloarthritis (EMAS)
Despite the increasing scientific knowledge on axSpAs, a substantial gap still remains. Delay in diagnosis continues to pose a threat in the early identification of patients and those already on treatment may deal with additional issues such as work productivity or quality of life.

Pre-clinical RA: starting off the wrong foot
Patients with clinically suspect arthralgia can represent a challenge for clinicians, in a sense that there are not yet reliable markers to predict evolution to clinical RA nor enough evidence to support routine prescription of conventional synthetic DMARDS or biologic treatments in this setting.

Detecting inflammation in SIJ for axSpA is by MRI but Artificial intelligence convolutional network aids this:
-In the Validation set: Trained CNN ▶️91.8% accuracy; Sens 88.9% Sp 93.5%
- Holdout set: 81.5% accuracy; Sens 67%; Sp 84.5%.

There are no MRI imaging difference in axSpA with psoriasis, coliitis or iritis. 240 patients in the SASPIC study show psoriatic axSpA similar to axSpA associated with iritis or colitis.

⭐️Total Body PET/CT (TB-PET/CT) as a tool to identify subclinical PsA at the point of transition from psoriasis (PsO).
➡️Should all pts w/ new dx of PsO have a baseline TB-PET/CT to identify early PsA?

Does tenderness in non-swollen joints of PsA or RA pts portend inflammation & radiographic damage?
⭐️NO, except in early PsA!
➡️Abnormal PDUS associated w/ radiographic progression vs tenderness otherwise

Blurred line indeed, one could argue that a patient with ACPA+, arthralgia and sub-clinical inflammation detected on MRI is already transitioning toward early RA and fall into the category of patients we should treat anyway. https://t.co/Y1JceOijK0

Torgutalp et al.
⭐️Included Early axSpA - 166 nr-axSpA (symptom duration ≤5 y) and 135 with r-axSpA (symptom duration ≤10 y) from German Cohort
⭐️Assessed TNFI use over 2 years and has shown🔽 in radiographic sacroiliitis progression.

Can we predict who which PsA pts will be radiographic progressors?
Abs#449 identified 103 candidate biomarker peptides corresponding to 69 proteins that could ID progressors
More data needed

Provocative study in pre-RA. SC Abatacept in patients with pre-clinical RA can:
-improvement MRI inflammation
-⬇️evolution to clinical RA at 6 months
-No new safety signal
Yes, but we need longer term follow-up and an estimation of NNT.

Pre clinical RA: don't miss the feet 🦶🏼! Among 577 patients
with clinically suspect arthralgia undergoing MRI:
-23% intermetatarsal bursitis > ACPA + 56% vs. 19%
-higher risk or RA HR 3.3.
Would we find the same results w/ US?

Accdg to this study by Dr. B VanDijk et al, intermetatarsal bursitis (IMB) was seen in 23% of clin suspect arthralgia(CSA) pts; predicted clinical arthritis in ACPA+; ⬆ frequent w/ synovitis & tenosynovitis
Addtl tool for early RA dx?

ARIAA study of abatacept in pre-RA. Abatacept ⬇️MRI inflammation and reduces progression to RA. Of course it does. Like all these studies, really not sure what this is telling us. Abstr#0455 #ACR21 @RheumNow https://t.co/yNVVZFBWDq

⭐︎ Tenosynovitis on MRI hand/foot in ACPA(-) undifferentiated oligo-arthritis pts is predictive of RA
➡️NPV 93%, Se 85%
⭐︎ BM edema not prognostic of RA development
Do you already use MRI to help detect early RA?

Pearls on Rheum imaging:
👉CPPD is not erosive
👉SC joint in OA is common (hard to image)
👉AC joint is 1st place OA affects shoulders (not GH)
👉Neuropathic OA progress rapidly, look at the TMTs
👉Get more views if you aren't seeing what you need
