New and Emerging Biologics and Jak Inhibitors for the Treatment of Prurigo Nodularis: A Narrative Review.

Prurigo nodularis (PN) is a chronic dermatological condition characterized by intensely pruritic nodules resulting from repeated scratching. Its pathogenesis involves neuroimmune dysregulation, inflammatory cytokines, and neural proliferation. Conventional treatments often provide limited relief, necessitating novel therapeutic approaches.

Potential role of leptin in Janus kinase 2 inhibitor-associated weight gain: a monocentric retrospective study.

Janus kinase (JAK) inhibitors are widely used for treating atopic dermatitis (AD) and alopecia areata (AA). Weight gain is an emergent adverse event associated with JAK inhibitors, particularly those acting on the JAK2 pathway. We conducted a retrospective monocentric two-cohort study, including 226 patients, to evaluate the prevalence of weight gain in patients with AD and AA who were treated with JAK inhibitors for ≥ 1 year.

Baricitinib for the treatment of severe alopecia areata: results from a 52-week multicenter retrospective real-world study.

Baricitinib, a JAK 1/2 inhibitor, is approved for treating severe alopecia areata (AA). This study aimed to evaluate the long-term effectiveness and safety of baricitinib in a real-world setting over 52 weeks. This multicenter retrospective study included 96 adult patients diagnosed with severe AA from 11 Italian Dermatology Units.

Real-life Effectiveness and Safety of Guselkumab in Moderate-to-Severe Plaque Psoriasis: A 104-Week Retrospective Single-Center Study.

Background: Guselkumab is a monoclonal antibody approved for treating moderate-to-severe plaque psoriasis. Long-term data on the effectiveness and safety of guselkumab in a real-world setting are still limited.

Materials And Methods: We conducted a 104-week monocentric retrospective study on 102 psoriasis patients, all treated with guselkumab for at least 16 weeks.

Practical Use of Upadacitinib in Patients with Severe Atopic Dermatitis in a Real-World Setting: A Systematic Review.

Upadacitinib is a selective Janus kinase inhibitor approved for the treatment of severe atopic dermatitis (AD). This systematic review aims to summarize the most recent data in terms of effectiveness and safety of upadacitinib in the treatment of severe AD in a real-world setting. The review included a comprehensive search of databases, including PubMed, Google Scholar and Web of Science, according to Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines.

Anti-interleukin-17 and anti-interleukin-23 biologic drugs for genital psoriasis: a single-center retrospective comparative study.

Genital psoriasis affects 3-33% of patients with psoriasis during the course of the disease, usually leading to a severe reduction in the patient's quality of life. This study aims to retrospectively assess the effectiveness of interleukin (IL)-23 and IL-17 inhibitors in a real-life population affected by moderate-to-severe plaque psoriasis with genital involvement coming from our dermatology department. A total of 86 patients with a diagnosis of moderate-tosevere plaque psoriasis with severe genital involvement were enrolled.

Real-Life Effectiveness and Safety of Risankizumab in 131 Patients Affected by Moderate-to-Severe Plaque Psoriasis: A 52-Week Retrospective Study.

Introduction: Risankizumab is a humanized monoclonal antibody that selectively targets interleukin-23. It is approved for treatment of moderate-to-severe plaque psoriasis. We conducted a 52-week monocentric retrospective study to evaluate the effectiveness and safety of risankizumab in a real-life setting.
