Fast Clinical Response of Bimekizumab in Nail Psoriasis: A Retrospective Multicenter 36-Week Real-Life Study

(1) Background/Objectives: Nail psoriasis (NP) is a chronic and difficult-to-treat disease, which causes significant social stigma and impairs the patients’ quality of life. Moreover, nail psoriasis is a true therapeutic challenge for clinicians. The presence of nail psoriasis can be part of a severe form of psoriasis and can have predictive value for the development of psoriatic arthritis. Our real-world-evidence multicenter study aims to evaluate the efficacy of bimekizumab in nail psoriasis. (2) Methods: A retrospective analysis of a multicenter observational study included 834 patients affected by moderate-to-severe psoriasis, in 33 Dermatologic Units in Italy, treated with bimekizumab from December 2022 to September 2023. Clinimetric assessments were based on Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and Physician’s Global Assessment of Fingernail Psoriasis (PGA-F) for the severity of nail psoriasis at 0, 12, 24, and 36 weeks. (3) Results: Psoriatic nail involvement was present in 27.95% of patients. The percentage of patients who achieved a complete clearance of NP in terms of PGA-F 0 was 31.7%, 57%, and 88.5% at week 4, 16, and 36, respectively. PASI 100 was achieved by 32.03% of patients at week 4, by 61.8% at week 16, and by 78.92% of patients at week 36. The mean baseline PASI was 16.24. The mean DLQI values for the entire group of patients at baseline, at week 4, at week 16, and at week 36 were 14.62, 3.02, 0.83, and 0.5, respectively. (4) Conclusions: Therapies that promote the healing of both the skin and nails in a short time can also ensure a lower risk of subsequently developing arthritis which is disabling over time. Bimekizumab proved to be particularly effective to treat NP, with a fast response in terms of complete clearance, with over 88.5% of patients free from NP after 36 weeks. The findings of our real-world study showed that patients with moderate-to-severe PsO and concomitant NP had significantly faster and more substantial improvements in NP up to 36 weeks with respect to previous research findings. Considering the rapid healing of the nail, the dual inhibition of IL17 A and F might have a great value in re-establishing the dysregulation of keratin 17 at the nail level.

Persistent Patient-Level Effect of Guselkumab at Consecutive 8-Week Dosing Visits and Over Time in Patients With Active Psoriatic Arthritis: Post Hoc Analysis of a 2-Year, Phase 3, Randomized, Controlled Study.

Group-level analyses from the phase 3 DISCOVER-2 trial of guselkumab demonstrated robust and durable improvements across psoriatic arthritis (PsA) domains. To specifically evaluate continuous disease control in individual patients, persistence of clinically relevant improvements was assessed, both at consecutive guselkumab dosing visits and over time. Post hoc analyses included biologic-naïve patients randomized to 100 mg of guselkumab at week 0, week 4, and then every 8 weeks (Q8W). Improvements in joint (minimal clinically important improvement [MCII] in Disease Activity Index for PsA [DAPSA; ≥7.25], clinical DAPSA [cDAPSA; ≥5.7]), skin (Investigator's Global Assessment [IGA] 0/1), and overall disease activity (patient global assessment of arthritis and psoriasis [PtGA Arthritis+Psoriasis; MCII ≥ 15 mm], PsA Disease Activity Score [PASDAS; MCII ≥ 0.8]) were assessed. Proportions of patients with maintenance of DAPSA and cDAPSA MCII at consecutive Q8W guselkumab dosing visits (ie, at weeks 4 and 12, weeks 12 and 20, etc through week 52) and patient-level durability of response through week 100 (Kaplan-Meier) were determined. Among 248 patients randomized to guselkumab Q8W, 93% to 99% maintained clinical improvement in joint disease at consecutive Q8W dosing visits through week 52 across time periods. Among guselkumab patients achieving MCII by week 24, estimated probabilities of maintenance of clinical improvement 100 weeks post achievement ranged from 68% (IGA 0/1) to 89% (PASDAS MCII). Median times to loss of improvement were not reached; estimated mean weeks of maintenance of improvement were 58.6, 52.4, 75.7, 83.6, and 76.7, respectively, for DAPSA, cDAPSA, IGA, PtGA Arthritis+Psoriasis, and PASDAS. Guselkumab provided highly durable patient-level improvements, both at consecutive Q8W dosing visits for joint disease activity and over time across PsA domains according to physician- and patient-driven assessments.

Image-Based Artificial Intelligence in Psoriasis Assessment: The Beginning of a New Diagnostic Era?

Psoriasis, a chronic inflammatory skin disease, affects millions of people worldwide. It imposes a significant burden on patients' quality of life and healthcare systems, creating an urgent need for optimized diagnosis, treatment, and management. In recent years, image-based artificial intelligence (AI) applications have emerged as promising tools to assist physicians by offering improved accuracy and efficiency. In this review, we provide an overview of the current landscape of image-based AI applications in psoriasis. Emphasis is placed on machine learning (ML) algorithms, a key subset of AI, which enable automated pattern recognition for various tasks. Key AI applications in psoriasis include lesion detection and segmentation, differentiation from other skin conditions, subtype identification, automated area involvement, and severity scoring, as well as personalized treatment selection and response prediction. Furthermore, we discuss two commercially available systems that utilize standardized photo documentation, automated segmentation, and semi-automated Psoriasis Area and Severity Index (PASI) calculation for patient assessment and follow-up. Despite the promise of AI in this field, many challenges remain. These include the validation of current models, integration into clinical workflows, the current lack of diversity in training-set data, and the need for standardized imaging protocols. Addressing these issues is crucial for the successful implementation of AI technologies in clinical practice. Overall, we underscore the potential of AI to revolutionize psoriasis management, highlighting both the advancements and the hurdles that need to be overcome. As technology continues to evolve, AI is expected to significantly improve the accuracy, efficiency, and personalization of psoriasis treatment.

The development and use of artificial intelligence (AI) in dermatology: a narrative review

Artificial intelligence (AI) is defined as a computer science involving program development aiming to reproduce human cognition to analyze complex data. Artificial intelligence has rapidly developed in the medical field. In dermatology, its development is relatively new and is generally used in the diagnostic, especially for skin imaging analysis and classification, and also for risk assessment. The greatest advances have been primarily in the diagnosis of melanoma, followed by the assessment of psoriasis, ulcers, and various other skin diseases. The use of AI has shown good accuracy and is comparable to dermatologists in various studies, especially related to melanoma and skin tumors. However, several obstacles exist in the application of AI to daily clinical practice, including generalizability, image standardization, the need for large data quantities, and legal and privacy aspects. In current developments, AI should be aimed at helping enhance the decision-making of clinicians.

Breakout Session and Report Back: Collaboration of Rheumatologists and Dermatologists for the Care of Patients With Psoriatic Disease.

Multidisciplinary care is essential for the management of patients with psoriatic disease (PsD), considering the great range of cutaneous and musculoskeletal symptoms and the potential for associated comorbidities and extraarticular manifestations. Consequently, combined rheumatology/dermatology clinics represent a gold standard model of care for patients with PsD. Many challenges are associated with the establishment of these clinics in routine clinical practice. In this report, we describe the thoughts and debates within a collaborative care breakout session during the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting. The breakout discussion focused around 3 main topics: (1) challenges of dermatologist-rheumatologist collaboration; (2) innovative approaches to encourage collaboration; and (3) how to identify patients with psoriasis at high risk of developing PsA.

GRAPPA Point-Counterpoint: Should Biologics Be Used for Mild Psoriasis?

Psoriasis (PsO) is commonly classified as mild, moderate, or severe, usually based on body surface area (BSA) or other validated measures. Although most dermatologists agree that mild PsO should be treated with topical therapies, there are circumstances where mild or limited PsO should be treated with biologics, even as first line. A debate about use of topical vs biologic therapy was presented at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting. Arguments in favor of using biologics when patients have mild disease on limited BSA included presence of psoriatic arthritis (PsA) and symptoms on special sites (ie, scalp, face, body folds, genitals, nails, palms, soles). New data suggest that treating limited or early PsO may decrease the risk of developing PsA. Arguments against using biologics for mild PsO focused on the definition of mild PsO, citing that limited BSA with PsA and significant quality of life impact should not be defined as mild. Truly mild PsO should be treated with topical agents, given their safety and relative low cost. The availability of newer agents like roflumilast and tapinarof have expanded therapeutic choice and have data supporting their use for treatment of special sites.

Unintended Consequences of Immune Therapy for Immune-Mediated Diseases: Paradoxical Psoriasis and Dupilumab-Associated Musculoskeletal Syndrome.

Two presentations at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting focused on unintended consequences of immunomodulatory therapy for psoriasis (PsO). Dr. Elizabeth Wallace presented on unintended consequences of tumor necrosis factor inhibitors for treating PsO and other inflammatory disorders. These consequences include paradoxical PsO, which is defined as unexpected new PsO cases or worsening PsO symptoms seemingly induced by treatment. Dr. Bruce Kirkham focused on unintended consequences of dupilumab treatment, which can include a musculoskeletal syndrome similar to psoriatic arthritis.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Celebrates Its 20th Anniversary.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) started in August 2003 with 40 initial participants and celebrated its 20th anniversary with 1036 members, many of whom attended the annual meeting in Dublin, Ireland, on July 15 to 17, 2023. GRAPPA arose from a need experienced by psoriatic arthritis (PsA) and psoriasis (PsO) investigators to meet to address questions related to psoriatic disease (PsD). Though other groups were meeting at the time to classify and discuss PsA, GRAPPA arose from a desire to include international clinical and investigational researchers of both dermatology and rheumatology. The organization has built awareness of PsO and PsA, developed and validated research assessment tools to measure clinical status and disease outcomes, published multiple treatment recommendations, supported basic and clinical research on PsD pathophysiology, fostered interactions across research fields, and educated the future generation of PsO and PsA researchers. The group continues to focus on major priorities affecting patients with PsD and will continue evolving in the next decades.

Prologue: Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 Annual Meeting.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting was held on July 13 to 15, 2023, in Dublin, Ireland, and was attended by 285 rheumatologists, dermatologists, trainees, patient research partners (PRPs), representatives of patient organizations, and industry partners. The 20th anniversary of GRAPPA was celebrated with a special presentation and archival video. Ahead of the meeting, the PRP Network met, a workshop was held by the International Dermatology Outcome Measures (IDEOM) group, and there was a workshop in which researchers discussed advancing ultrasound use to improve the management of psoriatic disease (PsD). Young-GRAPPA also held a workshop and business meeting. Multiple presentations highlighted important topics currently influencing PsD, including ensuring that patients are included in advancing research, the role of depression in PsD, the use of magnetic resonance imaging for spinal lesions, and animal models of PsD, among others. Debates focused on whether biologics should be used for mild psoriasis, whether methotrexate should remain the first-line treatment for PsD, and whether PsD is really a primary enthesitis driving joint synovitis. Here we provide an overview of the features of the GRAPPA 2023 annual meeting and introduce the manuscripts published together in this supplement as a meeting report.

GRAPPA 2023 Basic Science Workshop: What to Expect From Animal Models for Psoriatic Arthritis and Psoriasis.

Animal models help to drive research into psoriasis and psoriatic arthritis (PsA), particularly when studies in humans are not feasible. There are no animal models that perfectly mimic psoriatic disease (PsD) and so the pros and cons of each existing model must be considered for appropriate experimental design. Roughly, the existing animal models for PsD can be divided into 4 categories: (1) spontaneous models, (2) transgenic models, (3) inducible models, and (4) xenotransplantation models. Animal models in PsD are extremely important for dissecting and understanding molecular mechanisms of the disease process and for developing novel drugs. Animal models remain highly valuable for research in PsD in 2 scenarios. The first scenario is when complex interventions or analyses are required that are not feasible in humans due to technical, safety, or economic reasons. The second is when well-controlled study environments are required, such as dietary modifications, that would be challenging in humans. This topic was presented as part of the basic science workshops during the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting.

GRAPPA 2023 Collaborative Research Network Meeting.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Collaborative Research Network (CRN)/research committee met during the GRAPPA 2023 annual meeting. Updates were provided on GRAPPA research projects, including the Axial Involvement in Psoriatic Arthritis (AXIS), Axial Psoriatic Arthritis Molecular and Clinical Characterisation Study, Diagnostic Ultrasound Enthesitis Tool (DUET), and Sex- and Gender-Based Analysis of the Effectiveness of Advanced Therapies (SAGE) studies, as well as the Health Initiatives in Psoriasis and Psoriatic Arthritis Consortium European States (HIPPOCRATES) and Elucidating the Landscape of Immunoendotypes in Psoriatic Skin and Synovium (ELLIPSS) studies. The highlight of the meeting was a presentation and discussion on the use of digital tools to study psoriatic disease.

Advancing Basic and Translational Science: Highlights From the Basic Science Workshop at the GRAPPA 2023 Annual Meeting.

Contemporary translational and clinical research advances in psoriatic disease (PsD) were highlighted at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting basic science workshop. This year's workshop focused on key topics, including the significance of the annual GRAPPA meetings as a platform for collaboration and knowledge exchange. Discussions centered around expanding our understanding of tumor necrosis factor inhibitor (TNFi) treatment in PsD and enhancing early detection strategies for PsD comorbidities, specifically for the timely intervention and management of cardiovascular (CV) comorbidities. Insights on the role of the C-C chemokine receptor type 6 (CCR6) in PsD and psoriatic arthritis were provided, suggesting that blockade of CCR6 can reduce psoriasis-like dermatitis and joint inflammation in mouse models.

Composite Outcome Measures for Psoriatic Arthritis: OMERACT and 3 and 4 Visual Analog Scale Progress in 2023.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) psoriatic arthritis (PsA) working group provided updates at the GRAPPA 2023 annual meeting on its work to evaluate composite outcome measures for PsA. An ongoing systematic literature review is in progress to evaluate psychometric measurement properties using the OMERACT filter 2.2 for a list of candidate composite outcome measures, which include minimal disease activity (MDA), Disease Activity for Psoriatic Arthritis (DAPSA), American College of Rheumatology (ACR) response criteria, Psoriatic Arthritis Disease Activity Score (PASDAS), Composite Psoriatic Disease Activity Index (CPDAI), 3 visual analog scale (3VAS), and 4VAS. The performance of the 3VAS and 4VAS in clinical practice and a synthesis of new data were presented, including estimates for minimal clinically important differences and thresholds of meaning, discrimination and construct validity, and longitudinal construct validity. Numeric rating scale (NRS) versions of the VAS have also been tested. Performance characteristics and psychometric properties are similar to the ASSESS study, a UK multicenter study, indicating that the VAS scales may be feasible tools for routine clinical care with a preference for the 4VAS because of superior face validity and clinical utility.

Hot Topics: Depression in Individuals With Psoriasis and Psoriatic Arthritis.

Psoriasis and psoriatic arthritis are associated with an increased risk of mental health conditions such as depression and anxiety. People with psoriatic disease (PsD) are also more likely to die by suicide than those without. Mood disorders affect people with PsD in a multitude of ways, such as in effectiveness of care, response to treatment, remission rates, and quality of life. Although the links between PsD and mental health conditions have not been fully elucidated, this review will highlight recent studies investigating shared biologic mechanisms between depression and PsD. Since mental health disorders can be assessed and treated effectively, dermatologists and rheumatologists should be aware of the mental health burden in individuals with PsD to accomplish the following: (1) educate their patients with PsD about this association, (2) screen for mental health conditions on an ongoing basis in their clinical practice, (3) refer their patients with PsD to a mental health professional when needed, and (4) ensure selection of a safe PsD treatment in the setting of comorbid mental health disease. Finally, important treatment considerations for individuals with PsD and depression are reviewed. This topic was presented at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting.

GRAPPA 2023 Annual Meeting Report: Hot Topic Session on Measurement of Musculoskeletal Symptoms in Psoriatic Disease.

During the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting, the International Dermatology Outcome Measures (IDEOM) psoriatic disease (PsD) workgroup presented an update on their efforts toward measurement of musculoskeletal (MSK) symptoms in patients with PsD. Dr. Joseph Merola initiated the presentation emphasizing the vital importance of assessing MSK symptoms in patients with psoriasis (PsO) regardless of whether they have been diagnosed with psoriatic arthritis (PsA). He also discussed existing challenges for evaluating MSK symptoms in patients with PsO without a PsA diagnosis. Dr. Lourdes Perez-Chada then presented their work on the development and validation of the IDEOM Musculoskeletal Questionnaire (MSK-Q), a patient-reported questionnaire developed by the IDEOM to capture the intensity and impact of MSK symptoms on quality of life in patients with PsO with or without PsA. Dr. Perez-Chada also introduced a set of ongoing studies employing the IDEOM MSK-Q, highlighting the potential effects of the data collected through this innovative tool.

How to Involve Patients in GRAPPA Research as Partners.

Patient research partners (PRPs) have been actively participating in the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) annual meetings, working groups, and research activities since 2013. As they have evolved, the PRPs operate as a cohesive group supported by their GRAPPA-approved handbook and policy documents. The number of involved PRPs has increased, allowing more opportunity for the incorporation of the patient voice and experience in GRAPPA activities. In the GRAPPA proceedings, PRPs regularly report on their involvement in the meetings and research projects. During a 30-minute plenary session at the GRAPPA 2023 annual meeting, attendees were informed about the evolving roles of PRPs in GRAPPA and beyond and were asked to provide feedback on their experience and opinions regarding PRP involvement in psoriatic disease research. Here we report the key messages of the session, including polling results, examples of PRP involvement, and ongoing challenges.

Advances in Psoriatic Disease Research: Insights From GRAPPA Pilot Research Awardees.
