Key clinical point: Tofacitinib was more effective and as safe as placebo in men and women with psoriatic arthritis (PsA); however, men were more likely to achieve minimal disease activity (MDA) with tofacitinib due to differences in baseline disease activity.

Major finding: At 3 months, tofacitinib was more efficacious than placebo irrespective of sex (P < .001); however, MDA was achieved by a higher proportion of men vs  women receiving tofacitinib (P < .05), although the American College of Rheumatology 20/50/70 response was comparable. The incidence of treatment-emergent adverse events was similar in men and women receiving tofacitinib at doses of 5 mg (67.5% and 70.2%, respectively) or 10 mg (70.0% and 72.8%, respectively) twice daily.

Study details: This post hoc analysis of data pooled from phase 3 randomized controlled trials included 816 patients with PsA who received tofacitinib, adalimumab, or placebo.

Disclosures: This study was sponsored by Pfizer. Some authors declared being employees, holding shares, or having other ties with various sources, including Pfizer.

Key clinical point: COVID-19 vaccination was not associated with the worsening of disease activity in patients with psoriatic arthritis (PsA) who were treated with targeted therapies; however, COVID-19 vaccination may worsen disease activity in patients treated with interleukin-12/23 inhibitors (IL-12/23-i).

Major finding: The flare rate was not significantly different in the 6 months post-vaccination vs  the pre-vaccination period (P  =  .797), with no significant change in disease activity score in 28 joints before or after vaccination in the overall population. However, COVID-19 vaccination significantly worsened disease activity in patients treated with IL-12/23-i vs  tumor necrosis factor inhibitor (P  =  .019).

Study details: The data come from a prospective observational study including 1765 patients total with PsA (n = 587) or rheumatoid arthritis (n = 1178) treated with targeted therapies who were vaccinated for COVID-19 with any of the available vaccines.

Disclosures: This study was funded by Bristol-Myers Squibb, Galapagos Biopharma Spain SLU, and Roche Farma. Two authors reported ties with various sources, including Galapagos or Roche.

Key clinical point: Among malignancies, including breast cancer, melanoma, lymphoma, and non-melanoma skin cancer (NMSC), patients with moderate-to-severe atopic dermatitis (AD) had the highest incidence rate (IR) for NMSC followed by breast cancer and melanoma; NMSC incidence increased with age among patients with moderate but not severe AD.

Major finding: In patients with moderate and severe AD, the IR per 1000 person-years were 4.6 (95% CI 3.9-5.5) and 5.9 (95% CI 3.8-9.2) for NMSC, 2.2 (95% CI 1.6-3.0) and 0.5 (95% CI 0.1-3.9) for breast cancer, and 0.4 (95% CI 0.2-0.7) and 0.6 (95% CI 0.1-2.3) for melanoma, respectively. The NMSC IR increased with increasing age in patients with moderate AD (18-39 vs ≥65 years: 0.1 [95% CI 0.0-0.7] vs 18.0 [95% CI 13.9-23.2]).

Major finding: Compared with non-atopic and atopic control individuals, individuals with a maternal AD family history had a significantly higher risk for childhood-onset (adjusted odds ratio [aOR] 4.36, 95% CI 1.18-16.17; and aOR 32.97, 95% CI 4.03-269.68, respectively) and adult-onset AD (aOR 15.79, 95% CI 1.81-137.74; and aOR 34.15, 95% CI 3.15-370.28, respectively) and active smokers had an increased risk for adult-onset AD (aOR 5.54, 95% CI 1.06-29.01; and aOR 4.03, 95% CI 1.20-13.45, respectively).

Study details: This study analyzed the cross-sectional data of 736 adult individuals with childhood-onset (<18 years) or adult-onset (≥18 years) AD and 76 non-atopic and 91 atopic control individuals without AD.

Disclosures: This study was funded by the Christine Kühne-Center for Allergy Research and Education (CK-CARE), Switzerland. Some authors declared various ties, including employment, with CK-CARE or others.

Key clinical point: Long-term topical corticosteroid (TCS) and tacrolimus (TAC) treatments had similar efficacy and impact on airway hyperresponsiveness or inflammation in children with moderate-to-severe atopic dermatitis (AD).

Major finding: At month 36, children treated with TCS and TAC had no significant difference in the mean body surface area (P  =  .12), mean Eczema Area and Severity Index score (P  =  .2), mean Investigator’s Global Assessment Score (P  =  .12), mean transepidermal water loss at eczema site (P  =  .96) and control site (P  =  .19), median exhaled nitric oxide level (P  =  .71), or median bronchial hyperresponsiveness to methacholine (P  =  .7).

Study details: Findings are from a single-center 3-year follow-up study including 152 children aged 1-3 years with moderate-to-severe AD who were randomly assigned to receive TCS (n = 75) or TAC (n = 77).

Disclosures: This study was supported by the Foundation for Paediatric Research, Finland, Orion Research Foundation, Finland, Orion Pharma, Finland, Astellas Pharma, Japan, and others. Orion and Astellas are commercial manufacturers of the TCS used in this study.
