Effectiveness and Safety of Tildrakizumab in Elderly and Frail Elderly Psoriatic Patients Up to 2 years.

Purpose: Elderly patients with age ≥65 years represent an increasing percentage of the population with moderate-severe psoriasis. The definition of "frail elderly" is not easily framed, generally meaning a patient with unstable homeostasis. To date, there is no study in the literature examining possible differences between frail and non-frail elderly with psoriasis being treated with tildrakizumab.

Effectiveness of Dupilumab and Omalizumab in Bullous Pemphigoid: A Nationwide Retrospective Cohort Study.

Bullous pemphigoid (BP) is the most common autoimmune blistering skin disease worldwide. In the difficult-to-treat BP or if standard therapies are contraindicated, the use of biologics may be also considered although there is no strong evidence supporting their use. This study aimed to investigate clinical and diagnostic findings as well as treatment outcomes among patients diagnosed with BP and undergoing omalizumab or dupilumab in a real-world setting.

Keratin Variants in Pyoderma Gangrenosum: Pathogenetic Insights from a Whole-Exome Sequencing-Based Bioinformatic Analysis.

Pyoderma gangrenosum (PG) is an inflammatory skin disorder that belongs to the group of neutrophilic dermatoses. Clinically, it is typified by cutaneous ulcers with distinctive erythematoviolaceous borders and may occur alone or in association with other inflammatory, autoinflammatory, or neoplastic conditions. Although its pathophysiology remains incompletely understood, mounting evidence points toward a predisposing genetic background and dysregulation of both the innate and adaptive immune responses, with follicular or epidermal structures as putative initial targets.

Interleukin-13 in immunohistochemistry: implications for Grover disease, morphea, and immune checkpoint inhibitor-induced bullous pemphigoid.

Interleukin-13 (IL-13), a key T-helper 2 cytokine, has a central role in type 2 inflammation and is implicated in various skin disorders. This study investigated the IL-13 immunohistochemical expression in skin biopsies from patients with atopic dermatitis (AD), psoriasis vulgaris, morphea, Grover's disease, and immune checkpoint inhibitor-induced bullous pemphigoid (ICI-BP). AD biopsies showed the highest IL-13 expression (mean 27.

Paradoxical Psoriasis: An Updated Review of Clinical Features, Pathogenesis, and Treatment Options.

The definition of paradoxical psoriasis (PP) encompasses 2 main scenarios, namely, (i) new-onset psoriasis in patients treated for a different disease and (ii) worsening as well as phenotypical change of pre-existing psoriasis. Originally restricted to the appearance of an untoward psoriasiform reaction under TNF inhibitors, the term has gained new meaning, with the progressive observation of psoriasis-like eruptions also with other medications. Although the conceptual framework of PP has expanded, a molecular and clinicotherapeutic classification is still lacking.

Short-, mid- and long-term efficacy of dupilumab in moderate-to-severe atopic dermatitis: a real-world multicentre Italian study of 2576 patients.

Background: The efficacy and safety of dupilumab in atopic dermatitis (AD) have been defined in clinical trials but limited real-world evidence on long-term treatment outcomes is currently available to inform clinical decisions.

Objectives: To describe the long-term effectiveness and safety of dupilumab up to 48 months in patients with moderate-to-severe AD.

Methods: A multicentre, retrospective, dynamic cohort study was conducted to assess long-term effectiveness and safety of dupilumab in patients with moderate-to-severe AD in a real-world setting.

Hidradenitis Suppurativa-Related Autoinflammatory Syndromes: An Updated Review on the Clinics, Genetics, and Treatment of Pyoderma gangrenosum, Acne and Suppurative Hidradenitis (PASH), Pyogenic Arthritis, Pyoderma gangrenosum, Acne and Suppurative Hidradenitis (PAPASH), Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis (SAPHO), and Rarer Forms.

Hidradenitis suppurativa (HS) is an autoinflammatory skin disorder of the terminal hair follicle, which can present in sporadic, familial, or syndromic form. A classification has been proposed for the latter, distinguishing cases associated with a known genetic condition, with follicular keratinization disorders or with autoinflammatory diseases. This review focuses on the clinical and genetic features of those entities (ie, pyoderma gangrenosum [PG], acne and HS; PG, acne, pyogenic arthritis and HS; psoriatic arthritis, PG, acne and HS; synovitis, acne, pustulosis, hyperostosis, osteitis; and so forth) for which the collective term HS-related autoinflammatory syndromes is proposed.

Treatment of Psoriasis Patients with Latent Tuberculosis Using IL-17 and IL-23 Inhibitors: A Retrospective, Multinational, Multicentre Study.

Background: Tuberculosis has a major global impact. Immunocompetent hosts usually control this disease, resulting in an asymptomatic latent tuberculosis infection (LTBI). Because TNF inhibitors increase the risk of tuberculosis reactivation, current guidelines recommend tuberculosis screening before starting any biologic drug, and chemoprophylaxis if LTBI is diagnosed.

Vitiligo: Unmet Need, Management and Treatment Guidelines.

Vitiligo is a chronic depigmenting disorder characterized by characteristic, non-scaly, chalky-white skin macules and patches, due to the loss of skin pigment. Its exact pathogenesis is still not fully understood but it seems to be an autoimmune disease where the combination of genetic, environmental, and immune factors contributes to the destruction of melanocytes in the epidermis. Vitiligo is classified into different types based on its clinical characteristics and distribution patterns.

The Bowel-Associated Arthritis-Dermatosis Syndrome (BADAS): A Systematic Review.

Bowel-associated arthritis-dermatosis syndrome (BADAS) is a rare neutrophilic dermatosis that was first described in 1971 in patients who underwent bypass surgery for obesity. Over the years, the number of reported cases associated with medical gastroenterological conditions, particularly inflammatory bowel disease (IBD), has progressively increased. To date, there are no systematic reviews in the literature on BADAS.

Lymphomatoid papulosis associated with myeloid neoplasm with eosinophilia and FIP1L1::PDGFRA rearrangement: Successful imatinib treatment in two cases.

Lymphomatoid papulosis (LyP) is a benign condition, listed among primary cutaneous CD30+ lymphoproliferative disorders. Its typical picture consists of relapsing-remitting papular lesions and it can be encountered in the course of a hematologic disease, at times representing its first manifestation. Hypereosinophilic syndromes are a heterogeneous group of disorders characterized by persistent peripheral blood hypereosinophilia that may lead to life-threatening organ damage.

Mpox: an updated review of dermatological manifestations in the current outbreak.

Mpox is a disease caused by a double-stranded DNA orthopoxvirus discovered in 1958. In 2022, an outbreak on an unprecedented scale marked its transition from neglected, zoonotic disease circulating almost exclusively within African borders to sexually transmitted infection (STI) of international concern. Although phylogenetic evidence suggests progressive evolution from the strain associated with the 2018 outbreak in Nigeria, epidemiological links with previous cases have still not been completely elucidated.
