Spesolimab Reduces Inflammation in Generalized Pustular Psoriasis: Molecular Characterization of Flare Treatment in EFFISAYIL 1.

EFFISAYIL 1 was a randomized, placebo-controlled study of spesolimab, an anti-IL-36 receptor antibody, in patients presenting with a generalized pustular psoriasis flare. Treatment with spesolimab led to more rapid pustular and skin clearance versus treatment with placebo in approximately half of the patients. In this study, we present histologic, transcriptomic, and proteomic analyses of lesional and nonlesional skin and whole-blood samples collected from EFFISAYIL 1.

Clinical course, treatment and management of generalised pustular psoriasis from a United Kingdom extension of a global Delphi panel.

This article presents the results of the UK extension of a previously conducted global Delphi panel on generalised pustular psoriasis (GPP). Five UK based dermatologists experienced in GPP management have expressed their level of agreement on 101 questionnaire statements addressing four aspects of GPP: clinical course and flare definition, diagnosis, treatment goals, and holistic management. Consensus was achieved for 89 of 101 statements (88%).

Psychometric validation of the Psoriasis Symptom Scale, Functional Assessment of Chronic Illness Therapy-Fatigue and pain-Visual Analogue Scale in patients with generalized pustular psoriasis.

Background: Generalized pustular psoriasis (GPP) is a rare, chronic, inflammatory skin disease associated with considerable patient burden. The Psoriasis Symptom Scale (PSS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) and pain-Visual Analogue Scale (pain-VAS) are patient-reported outcomes (PROs) that have not yet been validated in patients with GPP.

Objectives: To evaluate the psychometric properties of the PSS, FACIT-Fatigue and pain-VAS using data from Effisayil 1, a randomised trial of spesolimab in patients with moderate-to-severe GPP.

Spesolimab, an interleukin-36 receptor monoclonal antibody, for the treatment of generalized pustular psoriasis.

Introduction: Generalized pustular psoriasis (GPP) is a rare cutaneous and systemic inflammatory disease which is characterized by flares of widespread painful pustulation of the skin, often associated with fever and elevated inflammatory markers. Although it has historically been regarded as a severe variant of plaque psoriasis, genetic and immunological developments over the past decade have revealed that it is a distinct auto-inflammatory entity, in which over-activity of the interleukin-36 signaling pathway is fundamental. Treatments targeting the IL-36 pathway are under investigation, and in 2022 spesolimab, a monoclonal antibody against the IL-36 receptor, was licensed for treating flares of GPP.

Contaminant Back Diffusion from Low-Conductivity Matrices: Case Studies of Remedial Strategies.

Recalcitrant groundwater contamination is a common problem at hazardous waste sites worldwide. Groundwater contamination persists despite decades of remediation efforts at many sites because contaminants sorbed or dissolved within low-conductivity zones can back diffuse into high-conductivity zones, and therefore act as a continuing source of contamination to flowing groundwater. A review of the available literature on remediation of plume persistence due to back diffusion was conducted, and four sites were selected as case studies.

Psychometric validation of the generalized pustular psoriasis physician global assessment (GPPGA) and generalized pustular psoriasis area and severity index (GPPASI).

Background: Generalized pustular psoriasis (GPP) is a rare and life-threatening skin disease often accompanied by systemic inflammation. There are currently no standardized or validated GPP-specific measures for assessing severity.

Objective: To evaluate the reliability, validity and responder definitions of the Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) and Generalized Pustular Psoriasis Area and Severity Index (GPPASI).

Clinical Characteristics and Outcomes of Generalized Pustular Psoriasis Flares.

Background: Generalized pustular psoriasis (GPP) is a rare, neutrophilic skin disease that can become life-threatening if flares are untreated. There are limited data describing the characteristics and clinical course of GPP disease flares with current treatment options.

Objective: The aim of the study was to describe the characteristics and outcomes of GPP flares using historical medical information from patients enrolled in the Effisayil™ 1 trial.

Design of Effisayil™ 2: A Randomized, Double-Blind, Placebo-Controlled Study of Spesolimab in Preventing Flares in Patients with Generalized Pustular Psoriasis.

Introduction: Generalized pustular psoriasis (GPP) is a rare autoinflammatory skin disease characterized by flares of widespread erythema with sterile pustules, and can be relapsing with recurrent flares, or persistent with intermittent flares. Spesolimab, a humanized anti-interleukin-36 (IL-36) receptor monoclonal antibody, targets the key IL-36 pathogenetic pathway in GPP. A previous study showed that spesolimab treatment led to rapid pustular and skin clearance in patients with GPP flares, which was sustained for up to 12 weeks.

Symptom Experience and Content Validity of the Psoriasis Symptom Scale (PSS) in Patients with Generalized Pustular Psoriasis (GPP).

Introduction: We sought to understand key symptoms of generalized pustular psoriasis (GPP) and to confirm the relevance to patients and content validity of the Psoriasis Symptom Scale (PSS) in GPP.

Methods: A targeted literature review and clinical expert interviews were conducted as background research. Patients were interviewed individually (involving concept elicitation and cognitive interviews), and a separate patient workshop was conducted to determine disease-specific symptoms of importance.

Single-cell analysis implicates T17-to-T2 cell plasticity in the pathogenesis of palmoplantar pustulosis.

Background: Palmoplantar pustulosis (PPP) is a severe inflammatory skin disorder characterized by eruptions of painful, neutrophil-filled pustules on the palms and soles. Although PPP has a profound effect on quality of life, it remains poorly understood and notoriously difficult to treat.

Objective: We sought to investigate the immune pathways that underlie the pathogenesis of PPP.

Clinical Disease Measures in Generalized Pustular Psoriasis.

Generalized pustular psoriasis (GPP) is a rare neutrophilic skin condition characterized by episodes of widespread eruption of sterile macroscopic pustules that can be associated with systemic inflammation. The rarity of GPP and its heterogeneous cutaneous and extracutaneous symptoms pose considerable challenges to the development and adoption of comprehensive accurate disease measures for the routine clinical assessment of disease severity and the evaluation of new treatments in clinical trials. Psoriasis disease measures remain among the most commonly used methods for evaluating patients with GPP, despite their limitations owing to a lack of assessment of pustules (a hallmark of GPP), systemic inflammation, and disease symptoms.

Trial of Spesolimab for Generalized Pustular Psoriasis.

Background: Generalized pustular psoriasis (GPP) is a rare, life-threatening, inflammatory skin disease characterized by widespread eruption of sterile pustules. Interleukin-36 signaling is involved in the pathogenesis of this disorder. Spesolimab, a humanized anti-interleukin-36 receptor monoclonal antibody, is being studied for the treatment of GPP flares.

Deteriorating Patient Training Using Nonimmersive Virtual Reality: A Descriptive Qualitative Study.

Recent nurse education pedagogical strategies are starting to embrace the use of virtual patient simulations in higher education settings. This study evaluated student, simulation technician, and lecturer perspectives on student performance after virtual training for care of a deteriorating diabetic patient. Second year nursing students learned using a virtual patient simulation, which was a follow-up of a randomized controlled trial that took place during the academic year 2017-2018.

Dysregulation of Connexin Expression Plays a Pivotal Role in Psoriasis.

Background: Psoriasis, a chronic inflammatory disease affecting 2-3% of the population, is characterised by epidermal hyperplasia, a sustained pro-inflammatory immune response and is primarily a T-cell driven disease. Previous work determined that Connexin26 is upregulated in psoriatic tissue. This study extends these findings.

The BSR-PsA: study protocol for the British Society for Rheumatology psoriatic arthritis register.

Background: Psoriatic arthritis (PsA) presents a unique clinical challenge. Affecting joints, skin, nails, and other organs, it is associated with various comorbidities and has a significant impact on quality of life, social participation and working life. While biologic and other targeted synthetic disease modifying anti-rheumatic drugs (bDMARDs and tsDMARDs) have revolutionised therapy, questions remain about the long-term safety of these agents, and their effectiveness and cost-effectiveness in the real-world clinical setting.
