Sleep Apnea in Psoriatic Arthritis – A Wake Up Call
Fatigue is one of the most disabling symptoms in psoriatic arthritis (PsA), yet its causes are often underexplored. At ACR 2025, Abstract #0549, a possible hidden contributor was studied: obstructive sleep apnea (OSA).

Stress Raises the Risk of Psoriasis
EurekAlert!
New longitudinal research reveals that severe stress caused by changes in family structure like divorce or separation experienced during the first year of life may triple the risk of developing psoriasis later in life.

A simple flow cytometry analysis of peripheral blood monocytes to predicts progression to clinical RA or PsA in at-risk patients?
Too good to be true!
284 RA 56 PsA 57 HC
-HLA-DR higher in PsA
-CD11c lower in RA
But no clear difference between Converters and non Converters https://t.co/f3Sett4eXd

PD-1+ effector memory T cells in PsA synovium are functionally active and regulate Th17 cytokines via STAT3/RORγt. Recombinant PD-L1 agonist significantly reduced T cell proliferation and IL-17A/F/IL-22 production highlighting checkpoint agonists as a novel therapeutic strategy https://t.co/I6eNa0j7aa

Effect of BioDMARDs on Diabetes risk in 6400+ Psoriasis pts
IL-23i and IL-17Ai associated w/
-lower risks of diabetes
-Diabetic nephropathy
-Stage 3–5 CKD
and reduced risk compared to TNFi treated and bionaive pts

Retrospective study by Dr. Goudot et al. - pts w/D2T PsA had dactylitis, fibromylagia & ischemic cardiomyopathy
In multivariate analysis, FM & ischemic CM found to be RFs for D2T PsA
☝️Consider other dx if D2T PsA

Icotrokinra, a first-in-class targeted oral peptide IL-23R inhibitor, cleared scalp (66%), genital (77%), and overall skin (57%) PsO vs placebo at Week 16. Basket trial design enabled targeted evaluation. Safety profile favorable. Abstract 0555 @RheumNow #ACR25

A systematic review by Dr. SRamiro et al evaluated efficacy of b/tsDMARDs on peripheral axSpA
Majority on bDMARDs (TNFi, n=24; IL-17, n=13)
Most of the SMDs were small --> b/tsDMARDs showed small to moderate effects on peripheral arthritis & enthesitis.

From the FOREMOST study factors predicting progression from oligo to polyarticular PsA: Female sex, enthesitis and dactylitis found to increase the risk of progression. Among patients in FOREMOST receiving PBO, prior csDMARD use was protective. Abstract#0576 @RheumNow #ACR25 https://t.co/CFMhAFgFBa

Real-world T2T strategy from MONITOR-PsA cohort:
🎯 At 48 weeks - 33.6% (49/146) of pts achieved PASDAS 'moderate' response & 37% (54/146) achieved a 'good' response
This was close to the T2T outcomes of the TICOPA trial
Adapt a T2T approach in PsA tx

This retrospective cohort analysis by Dr. Lihi Eder et al showed that among patients with PsA, those w/ high dse activity & high 3VAS scores were assoc w/⬆️ risk of atrial tachyarrythmias.
Main message: PsA conveys ⬆️CV risk; inflamm control is key!

Mediterranean Diet Efficacy in Psoriasis
A small clinical trial found that a 16-week Mediterranean diet reduced psoriasis severity, presumably due to anti-inflammatory benefits of extra virgin olive oil, plant-based foods, and moderate meat consumption, according to a study https://t.co/fiJTx6TEZq
