Participants completed quality of life and physical activity questionnaires and underwent a clinical examination of both joints and entheses, followed by a detailed musc

Objectives To test the hypothesis that recently-developed total body-positron emission tomography (TB-PET) imaging with integrated computed tomography (CT) will enable low-dose, quantitative, domain-specific evaluation of the total inflammatory burden of psoriatic arthritis (PsA) and associate with established outcome measures of the clinical domains of PsA.Methods Seventy-one adult participants (40 with PsA, 16 with rheumatoid arthritis (RA), and 15 with osteoarthritis (OA)) underwent 20-min TB

Objective Psoriatic arthritis (PsA) guidelines aim to provide consistent, evidence-based recommendations. Multiple regional guidelines exist, often based on similar evidence but with different methodologies and contexts. Our aim was to compare recent PsA treatment guidelines from the American College of Rheumatology, Group for Research and Assessment of Psoriasis and Psoriatic Arthritis, European Alliance of Associations for Rheumatology, and Pan American League of Associations for Rheumatology,

Introduction Difficult-to-treat psoriatic arthritis (D2T-PsA) is increasingly recognized as a complex clinical entity characterized by persistent disease burden despite multiple targeted therapies. Its identification is essential to improve patient outcomes and to guide the development of new therapeutic strategies.Areas covered In this perspective article, we discuss the evolving concept of D2T-PsA, including its epidemiology, clinical characterization, and underlying pathophysiological mechani

Context Evidence regarding the relationship between serum trace element levels and immune-mediated inflammatory skin diseases (IMSDs) is inconsistent.Objective In this systematic review and meta-analysis we aimed to evaluate the association between selected serum trace element levels (zinc [Zn], copper [Cu], iron [Fe], selenium [Se], and calcium [Ca]) and IMSDs (psoriasis, vitiligo, atopic dermatitis [AD], alopecia areata [AA], hidradenitis suppurativa, and bullous diseases).Data sources We cond

Justification and objectives: Topical therapy is vital in the management of psoriasis. In recent years there have been multiple advances and changes in the management of psoriatic patients that justify a review and update of the use of topical therapy. Experts from the Spanish Psoriasis Working Group (GPS) of the Spanish Academy of Dermatology Venereology (AEDV) have developed a set of recommendations for the treatment of psoriasis based on the best available evidence and experts' opinion. Metho

Secukinumab, a fully human monoclonal antibody that antagonizes interleukin-17A (IL-17A), has proven efficacious in the management of moderate to severe plaque psoriasis. Secukinumab has established itself as an effective treatment for plaque psoriasis, offering rapid and sustained symptom improvement. However, more research is warranted to assess its efficacy and safety in elderly patients, where clinical data is currently lacking. We describe an 84-year-old female presented with stable angina

Generalized pustular psoriasis (GPP) is a potentially life-threatening infrequent immune-mediated disease characterized by rapid-onset of erythematous plaques, sterile pustules, and systemic inflammation. Spesolimab, a monoclonal antibody targeting the interleukin-36 receptor, is a novel treatment for GPP. However, GPP's low incidence and limited evidence represents a challenge in determining its real-world efficacy. This review aims to explore the clinical use of spesolimab in a real-world sett

Keratinocyte hyperproliferation and excessive inflammatory responses are associated with psoriasis pathogenesis. Trifolirhizin has anti-inflammatory and anti-proliferation effects. The purpose of the study was to investigate the role of trifolirhizin in psoriasis-like skin lesions and its molecular mechanism. Imiquimod-induced psoriasis-like mouse models were treated with trifolirhizin. Skin lesions and inflammatory factors were assessed. In vitro, human HaCaT keratinocytes were stimulated by a

Background Genetic susceptibility to psoriasis involves multiple loci, including TYK2 (Tyrosine Kinase 2), which is associated with various autoimmune diseases. However, its specific role and mechanisms in psoriasis remain unclear. This study aimed to identify psoriasis-associated proteins using Summary-based Mendelian Randomization (SMR) and to explore their regulatory mechanisms.Methods SMR analysis integrating pQTL data was conducted to identify proteins linked to psoriasis, revealing ICAM1 (

Introduction Research findings show a substantial correlation between Crohn's disease and psoriasis. However, the exact cause or pathogenesis of the concurrent manifestations of these two conditions in the same individuals remains uncertain. This research aimed to scrutinize the important molecules and mechanisms responsible for the concomitance of Crohn's disease and Psoriasis by using quantitative bioinformatics utilizing a publicly available RNA sequencing repository.Methods The database Gene

Enthesitis represents a hallmark feature and central pathological process in psoriatic arthritis and has been proposed as a potential early indicator in patients with psoriasis prior to the onset of clinically apparent psoriatic arthritis. Given the risks associated with delayed diagnosis, there is growing interest in identifying at-risk patients early to enable timely interventions and personalized treatment approaches. In clinical practice, dermatologists are often the first to encounter these
