Tanaka et al. observed that in Japanese patients with rheumatoid arthritis treated with tofacitinib, those with absolute lymphocyte counts (ALCs) <0.5x10³ cells/mm³ had a higher risk of serious infections and herpes zoster events compared to patients with higher ALC levels. This threshold may help identify increased infection risk in this population

Risankizumab for Ulcerative Colitis Two Randomized Clinical Trials

JAMA. 2024;332:881-897 doi: 10.1001/jama.2024.12414

Louis et al. demonstrated risankizumab to significantly improve clinical remission rates compared to placebo in both an induction trial and in a maintenance trial for patients with moderately to severely active ulcerative colitis.

Phase 2 Trial of Anti-TL1A Monoclonal Antibody Tulisokibart for Ulcerative Colitis

N Engl J Med. 2024;391:1119-1129 doi: 10.1056/NEJMoa23140

Sands et al. demonstrated that 12-week treatment of tulisokibart, a monoclonal antibody targeting TL1A, significantly improved clinical remission rates compared to placebo in patients with moderate-to-severe ulcerative colitis.

Efficacy of Janus kinase inhibitors in the treatment of psoriasiform atopic dermatitis

Clin Exp Dermatol. 2024 Sep 18;49:1232-1234 doi: 10.1093/ced/llae16

Napolitano et al. conducted a retrospective analysis on patients with moderate-to-severe psoriasiform atopic dermatitis (AD) treated with JAK inhibitors, showing significant improvements in disease severity scores (EASI, P-NRS, DLQI) by Week 4, with 95% of patients achieving EASI-75 and 86% achieving EASI-90 by Week 24.

Kristensen et al. compared 14 PsA drugs across five treatment classes, evaluating their real-world effectiveness over three months. Ixekizumab showed rapid effectiveness on joint disease activity and skin outcomes, performing better than IL-12/23i and IL-23i, and comparable to TNFi and JAKi. More patients with active psoriasis achieved minimal disease activity with Ixekizumab than other therapies.

Su et al. conducted a comprehensive systematic review and network meta-analysis to assess the efficacy and safety of therapies for difficult-to-treat (D2T) RA. They found that tocilizumab and rituximab had superior efficacy and safety profiles, with 8mg every 4 weeks of tocilizumab identified as the optimal therapeutic dose.

Ghani et al. compared the efficacy and safety profiles of tapinarof and roflumilast for treating mild-to-moderate plaque psoriasis. Both therapies showed robust efficacy and were well-tolerated, with low rates of adverse events. Tapinarof exhibited marginally higher efficacy in PASI scores compared to roflumilast.

Cai et al. demonstrated that xeligekimab significantly improved the Psoriasis Area and Severity Index (PASI) scores in patients with moderate-to-severe plaque psoriasis, with 90.7% achieving PASI 75 at week 12. Xeligekimab was well-tolerated with no unexpected safety concerns.

Peyrin-Biroulet et al. evaluated the efficacy and safety of etrasimod in patients with moderately to severely active isolated proctitis, demonstrating significant improvement in clinical outcomes compared to placebo. The study reported a favourable safety profile, making etrasimod a viable treatment option for this population.

Magro et al. evaluated histologic outcomes for mirikizumab in Crohn's disease and found that early combined histologic-endoscopic response was associated with endoscopic remission after 1 year of treatment.
