Psoriatic Arthritis

Key clinical point: Achievement of low or minimal disease activity levels with guselkumab therapy diminished radiographic progression over 2 years in patients with psoriatic arthritis (PsA) at risk for radiographic damage.

Major finding: Among patients receiving guselkumab, the mean change in total van der Heijde-Sharp score from 0 to 100 weeks was numerically lower among those who achieved clinical response at week 52 vs non-responders, as assessed by ≥20% improvement in American College of Rheumatology criteria (1.0-1.2 vs 2.8-4.1), PsA Disease Activity Score low disease activity (LDA; 1.0 vs 1.9-2.4), and Disease Activity in PsA LDA (0.7-0.9 vs 2.3-3.1).

Study details: The data come from a post hoc analysis of the DISCOVER-2 study including 664 biologic-naïve patients with PsA who received guselkumab or placebo.

Disclosures: This study was funded by the Janssen Research & Development, LLC. Some authors reported ties with various sources, including Janssen. Some authors declared being employees of Janssen and owning stocks in Johnson & Johnson.

Key clinical point: Early initiation of apremilast led to rapid and sustained improvements in psoriatic arthritis (PsA) manifestations with a consistent safety profile in a real-world cohort of biologic-naive patients who were intolerant of conventional synthetic disease-modifying antirheumatic drugs (csDMARD).

Major finding: Among patients with baseline swollen joint count (SJC) and tender joint count (TJC) of >0, significant median decreases in SJC (50% and 90%, respectively) and TJC (50% and 80%, respectively) were observed at 16 and 52 weeks (all P < .001), with 55.2% of evaluable patients achieving minimal disease activity at 52 weeks. Overall, 13.8% of patients experienced ≥1 adverse event, with all except one being non-serious.

Study details: This prospective study included 167 biologic-naive patients with early peripheral PsA and intolerance or inadequate response to csDMARD who initiated apremilast.

Key clinical point: In patients with moderate-to-severe psoriasis, the presence of synovio-enthesitis on ultrasound, particularly in lower limbs, indicated progression to subclinical psoriatic arthritis (PsA). Therefore, routine ultrasound screening should be performed irrespective of arthritis symptoms.

Major finding: Only synovio-enthesitis diagnosis differed significantly among patients with silent psoriasis vs control individuals (16.1% vs 1.3%; P < .001), with 12.7% of patients diagnosed with synovio-enthesitis progressing to subclinical PsA and the top four sites with synovio-enthesitis involvement being in lower limbs. Body surface area and Psoriasis Area and Severity Index scores were not different in psoriasis, subclinical PsA, and prodromal/active PsA phases.

Study details: This cross-sectional study included 490 patients with moderate-to-severe psoriasis, of which 384 and 106 patients without and with arthritis symptoms formed the silent psoriasis and clinical PsA groups, respectively, and 80 age- and sex-matched control individuals without psoriasis.

Key clinical point: All Janus kinase inhibitors (JAKi) were more effective than placebo in patients with psoriatic arthritis (PsA), but led to a higher overall incidence of adverse events, particularly at higher doses.

Major finding: JAKi vs placebo were associated with a significantly higher American College of Rheumatology 20 response rate (relative risk [RR] 2.09; P < .00001), with the response being the highest for filgotinib (RR 2.40; P < .00001), followed by upadacitinib, tofacitinib, and deucravacitinib. However, the overall incidence of adverse events was higher with JAKi vs placebo (RR 1.17; P < .00001) and significantly higher with 10 mg vs 5 mg tofacitinib (P = .03).

Study details: The data come from a systematic review and meta-analysis of 17 phase 2/3 randomized controlled trials including 6802 patients with PsA or moderate-to-severe plaque psoriasis who received ≥1 JAKi.

Major finding: At week 24, a significantly higher proportion of patients receiving guselkumab every 4 or 8 weeks (Q4W or Q8W) vs placebo (63.5% or 59.4% vs 42.2%, respectively; P < .05) achieved dactylitis resolution; approximately 80% of patients receiving guselkumab achieved ≥70% improvement in dactylitis severity score by week 52. Patients with resolved dactylitis at week 24 were more likely to achieve American College of Rheumatology 50 response and other clinical outcomes (P < .05).

Study details: This pooled analysis included 1120 patients with active PsA from the phase 3 DISCOVER-1 and DISCOVER-2 studies who were randomly assigned to receive 100 mg guselkumab Q4W or Q8W or placebo.

Key clinical point: Women with psoriatic arthritis (PsA) were at an increased risk for emergency caesarean section, with active disease in the third trimester further amplifying the risk, highlighting the importance of pregestational counseling and disease control along with systematic monitoring during pregnancy.

Major finding: Compared with control individuals, women with PsA had a higher risk for caesarean section (risk difference [RD] 15.0%; P < .001) and for emergency caesarean section (RD 10.6%; P < .001), with active disease in the third trimester further amplifying both risks (caesarean section: RD 17.7%; P = .028; emergency caesarean section: RD 15.9%; P = .015).

Study details: The data come from a population-based cohort study that included women with PsA (n = 121), women with axial spondyloarthritis (n = 312), and control individuals (n = 575,798) with singleton births.

Disclosures: This study was funded by The Norwegian Women’s Public Health Association. The authors did not declare any conflicts of interest.
