Psoriatic Arthritis

Key clinical point: Improvements in inflammatory arthritis, pain, physical functioning, and the use of tumor necrosis factor (TNF) inhibitors were associated with patient-reported treatment success in patients with psoriatic arthritis (PsA).

Major finding: Increased odds for patient-reported treatment success was seen with TNF inhibitors therapy (odds ratio [OR] 12.86, 95% CI 1.50-110.47), while pain, fatigue, and swollen and tender joint counts reduced the odds of treatment success (OR < 1.00, P < .05). Each point increase in the physical function score was associated with 12%-14% increased odds of treatment success.

Study details: This single-center study included 178 patients with PsA, of which 116 patients reported treatment success.

Disclosures: This study was supported by Celgene; Amgen; Johns Hopkins School of Medicine Biostatistics, Epidemiology and Data Management Core; and others. Two authors declared serving as principal investigators or private consultants for or having other ties with various sources, including Amgen or John Hopkins University. The other authors declared no conflicts of interest.

Key clinical point: Patients with psoriatic arthritis (PsA) who did or did not respond to treatment with tumor necrosis factor alpha inhibitor (TNFi) and interleukin-17A inhibitor (IL-17Ai) showed different profiles of pro- and anti- inflammatory cytokines.

Major finding: At 4 months of follow up, a significant decrease in IL-6 (P  =  .032) and an increase in IL-10 (P  =  .010) was seen in patients achieving ≥ 50% improvement in Disease Activity in PsA (DAPSA50) response with TNFi treatment. IL-17Ai treatment showed decrease in IL-1α and IL-27 levels in DAPSA50 responders and increase in IL-17A in both DAPSA 50 responders and non-responders (all P < .05).  

Study details: This study included 68 patients with PsA who were initiated with TNFi (n = 29), IL-17Ai (n = 19), or methotrexate (n = 20) treatment and were followed for 4 months.

Key clinical point: Bimekizumab (160 mg/4 weeks) demonstrated favorable efficacy outcomes over secukinumab (150 mg or 300 mg/4 weeks) in patients with psoriatic arthritis (PsA) who were naive to biologic disease-modifying anti-rheumatic drugs (bDMARD) or had prior inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR).

Major finding: In the bDMARD naive subgroup, the probability of achieving at least 70% improvement in American College of Rheumatology (ACR) response was higher with bimekizumab vs secukinumab (odds ratio > 2; P < .05) at week 52, with similar response in the TNFi-IR subgroup for ACR70 and minimal disease activity outcomes (all P < .05).

Study details: This study included data of bDMARD naive or TNFi-IR patients with PsA who received bimekizumab from BE OPTIMAL (n = 236) and BE COMPLETE (n = 146) and secukinumab from FUTURE 2 trial (n = 200).

Key clinical point: Real-world treatment with guselkumab for ≥6 months was effective and safe in patients with longstanding active psoriatic arthritis (PsA) who had median disease duration of 6 years.

Major finding: Disease Activity Index for Psoriatic Arthritis (DAPSA) scores reduced significantly by 15.47 points in guselkumab-treated patients with PsA (P  =  .001), with 39.6% of patients achieving low disease activity, as assessed by achievement of DAPSA ≤ 14 at 6 months of follow-up. Guselkumab was well tolerated, with no reports of new safety signals.

Study details: This was a prospective real-world cohort study including 111 patients with active, longstanding PsA with a median disease duration of 6 years, who received guselkumab for ≥6 months.

Key clinical point: A long delay (>1 year) in diagnosing psoriatic arthritis (PsA) is associated with worse clinical outcomes, especially in women and patients with enthesitis, chronic back pain, and lower C-reactive protein (CRP) levels.

Major finding: Patients with a short (<12 weeks) vs long delay (>1 year) in PsA diagnosis after symptom onset was more likely to achieve minimum disease activity (odds ratio 2.55; 95% CI 1.37-4.76). Female sex, chronic back pain (age < 45 years), enthesitis, and lower CRP levels were associated with a diagnostic delay > 1 year in patients with PsA (all P < .05).

Study details: This study included 708 newly diagnosed patients with PsA who were followed up for ≥3 years; were naive to disease-modifying antirheumatic drugs; and were categorized into groups having short (n  =  136), intermediate (12 weeks to 1 year; n  =  237), or long (n  =  335) delay to diagnosis after symptom onset.

Key clinical point: Higher relative abundance of gut microbiota belonging to family Rikenellaceae and an unidentified metabolite X-11538 were associated with a reduced risk for psoriatic arthritis (PsA), highlighting the potential of gut microbiota taxa and metabolites as biomarkers for treatment and prevention of PsA.

Major finding: Adjusted multivariable Mendelian randomization analysis showed that a higher relative abundance of microbiota belonging to the family Rikenellaceae (odds ratio [OR] 0.5; 95% CI 0.320-0.780) and elevated serum levels of X-11538 (OR 0.448; 95% CI 0.244-0.821) were causally associated with a reduced risk for PsA.

Study details: This Mendelian randomization study included summary level data of gut microbiota taxa (n  =  18,340), PsA (n  =  339,050), and metabolites (n  =  7824) from participants included in the MiBioGen consortium, FinnGen Biobank, and TwinsUK and KORA cohorts, respectively.

Disclosures: This study was sponsored by UCB Pharma. Four authors reported being employees or shareholders of UCB Pharma. Several authors declared receiving research support or consulting fees or having other ties with various sources, including UCB Pharma.

Key clinical point: Bimekizumab led to long-term improvements in efficacy outcomes and had a manageable safety profile in patients with active psoriatic arthritis (PsA) and prior inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR).

Major finding: At week 16, a significantly higher number of patients achieved ≥50% improvement in American College of Rheumatology response with bimekizumab vs placebo (43.4% vs 6.8%; P < .0001), with improvements sustained up to week 52 by >40% of patients receiving bimekizumab. No new safety signals were observed.

Key clinical point: The incidence rates of major adverse cardiovascular events (MACE) were similar in patients with psoriatic arthritis (PsA) and rheumatoid arthritis (RA), suggesting that both inflammatory disorders share a common atherogenic mechanism.

Major finding: After a total of 119,571 patient-years of follow-up, 6.7% of patients with RA or PsA developed MACE for the first time. The rates of MACE incidence (adjusted incidence rate ratio 0.96; P  =  .767) and MACE-free survival (P  =  .987) were comparable between patients with PsA and RA. Higher time-varying erythrocyte sedimentation rate, C-reactive protein levels, and exposure to glucocorticoids increased the risk for MACE in both patients with PsA and RA (all P < .05).

Study details: This population based retrospective cohort study included 13,905 patients with PsA (n  =  1672) or RA (n  =  12,233) who did not have any previous history of MACE.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Key clinical point: Ixekizumab was more effective than adalimumab in resolving distal interphalangeal (DIP) joint tenderness, swelling, and adjacent nail psoriasis in patients with psoriatic arthritis (PsA) and DIP joint involvement who nearly invariably had adjacent nail psoriasis.

Major finding: More than 96% of patients with PsA and simultaneous DIP joint involvement reported adjacent nail psoriasis in at least one digit in the finger unit. Ixekizumab vs adalimumab led to greater improvements in DIP involvement and adjacent nail psoriasis as early as week 12 (38.8% vs 28.4%; P < .0001), with improvements sustained up to week 52 (64.9% vs 57.5%; P  =  .0055).

Study details: This post hoc analysis of the SPIRIT-H2H study included 354 patients with PsA who had simultaneous DIP joint involvement and adjacent nail psoriasis and were randomly assigned to receive ixekizumab or adalimumab.
