Baseline Characteristics of Canadian Patients in the Psoriasis Longitudinal Assessment and Registry (PSOLAR).

BACKGROUND: The Psoriasis Longitudinal Assessment and Registry (PSOLAR) is a global, prospective, longitudinal, disease-based registry. It serves as a post-marketing safety commitment with a focus on patients with moderate to severe plaque psoriasis who are candidates for systemic therapy. OBJECTIVES: To describe the baseline disease demographics and clinical characteristics of a Canadian subgroup of participants enrolled in PSOLAR. METHODS: Baseline demographic/disease characteristics, medical histories, and previous psoriasis treatments for Canadian patients in PSOLAR were summarized using descriptive statistics. RESULTS: There were 1896 patients analyzed in the Canadian subgroup at 37 clinical sites, accounting for 15.7% of the global PSOLAR population. Baseline disease and clinical characteristics were as expected for a moderate to severe psoriasis population and were generally similar to the global PSOLAR population. Two distinctions were noted in the Canadian subgroup versus those enrolled globally: a higher proportion of patients were overweight/obese (84.7% vs. 80.4%) and male (61.4% vs. 54.7%). In addition, the Canadian subgroup had numerically higher historical peak disease activity (PGA score 3.35 vs. 3.1) and longer disease duration (22.3 years vs. 17.5 years). Canadian PSOLAR patients reported a variety of comorbidities, including psoriatic arthritis (31.5%), hypertension (34.6%), hyperlipidemia (24.3%), mental illness (24.1%), and inflammatory bowel disease (1.6%). CONCLUSION: The Canadian subgroup of PSOLAR patients was generally similar to those enrolled globally with respect to baseline disease demographics and clinical characteristics. Multiple comorbidities are noted in the Canadian subgroup, underscoring the need for a holistic approach to the treatment of psoriatic patients.

Real-World Moderate-to-Severe Hidradenitis Suppurativa: Decrease in Disease Burden With Adalimumab.

BACKGROUND: Real-world knowledge of the burden of hidradenitis suppurativa (HS) on patients remains limited. OBJECTIVES: To measure the impact of adalimumab on moderate-to-severe HS patients' health-related quality of life (HRQoL) and work productivity. METHODS: In 23 Canadian centres, 138 adults with moderate-to-severe HS requiring a change in ongoing therapy were treated with adalimumab for up to 52 weeks as per the physician's practice. Patient-reported outcome measures (PROMs) were obtained at baseline, weeks 24 and 52 to measure overall HRQoL, HS severity, levels of anxiety and depression, impact and symptoms of HS, work productivity and activity impairment. A post-hoc analysis further explored the PROMs by abscess and inflammatory nodule (AN) count at baseline (≤5, low; 6-10, medium; ≥11, high). RESULTS: From baseline to weeks 24 and 52, all PRO overall scores improved significantly (P ≤ .0023). The number of patients reporting "good disease control" and "complete disease control" increased from 9.7% to 66.4% over 52 weeks. The score in Health Utility Index Mark 3 (HUI3) pain attribute meaningfully decreased over 52 weeks (mean difference ≥.05). The HS symptoms skin "tenderness" and "itchiness" improved the most. Work productivity loss and activity impairment improved by approximately 20% over 52 weeks. Disease burden improved more in 24 week responders with low and medium AN counts at baseline than in those with high AN count or in 24 week nonresponders. CONCLUSION: At week 24 and maintained at week 52 in a real-world setting, adalimumab meaningfully improved HRQoL, work productivity, and activity impairment in moderate-to-severe HS patients.

The Proposed PASI-HD Provides More Precise Assessment of Plaque Psoriasis Severity in Anatomical Regions with a Low Area Score.

The Psoriasis Area and Severity Index (PASI) is the most widely used clinical measure in clinical trials to assess disease severity of plaque psoriasis. However, the PASI is not a precise measure of severity with less precision when the regional area of involvement is < 10% of the BSA of a specific anatomical region. Degradation of precision results from the area score defaulting to '1' when the area of involvement within an anatomical region falls between 0% and 10% of the BSA for a given anatomical region. We describe a modification to the PASI, termed PASI-high discrimination (PASI-HD), for determination of more accurate psoriasis severity in body regions where < 10% of the body surface area is affected. The methodology for assessing disease severity in these conditions is described.

Qualitative Assessment of Adult Patients' Perception of Atopic Dermatitis Using Natural Language Processing Analysis in a Cross-Sectional Study.

INTRODUCTION: Atopic dermatitis (AD) is an incurable, inflammatory skin disease characterized by skin barrier disruption and immune dysregulation. Although AD is considered a childhood disease, adult onset is possible, presenting with daily sleep disturbance and functional impairment associated with itch, neuropsychiatric issues (anxiety and depression), and reduced health-related quality of life. Although such aspects of adult AD disease burden have been measured through standardized assessments and based on population-level data, the understanding of the disease experienced at the patient level remains poor. This text-mining study assessed the impact of AD on the lives of adult patients as described from an experiential perspective. METHODS: Natural language processing (NLP) was applied to qualitative patient response data from two large-scale international cross-sectional surveys conducted in the USA and countries outside of the USA (non-USA; Canada, France, Germany, Italy, Spain, and the UK). Descriptive analysis was conducted on patient responses to an open-ended question on how they felt about their AD and how the disease affected their life. Character length, word count, and stop word (common words) count were evaluated; centrality analysis identified concepts that were most strongly interlinked. RESULTS: Patients with AD in all countries were most frequently impacted by itch, pain, and embarrassment across all levels of disease severity. Patients with moderate-to-severe AD were more likely than patients with mild AD to describe sleep disturbances, fatigue, and feelings of depression, anxiety, and a lack of hope that were directly associated with AD. Centrality analysis revealed sleep disturbance was strongly linked with itch. Collectively, these concepts revealed that patients with AD are impacted by both physical and emotional burdens that are intricately connected. CONCLUSIONS: Qualitative data from NLP, being more patient-centric than data from clinical standardized measures, provide a more comprehensive view of the burden of AD to inform disease management.

Approach to the Assessment and Management of Adult Patients With Atopic Dermatitis: A Consensus Document.

BACKGROUND:: Atopic dermatitis (AD) is a chronic, relapsing, and remitting inflammatory skin disease with complex pathophysiology, primarily driven by type 2 inflammation. Existing guidelines often do not reflect all current therapeutic options and guidance on the practical management of patients with AD is lacking. OBJECTIVES:: To develop practical, up-to-date guidance on the assessment and management of adult patients with AD. METHODS:: An expert panel of 17 Canadian experts, including 16 dermatologists and 1 allergist, with extensive clinical experience managing moderate-to-severe AD reviewed the available literature from the past 5 years using a defined list of key search terms. This literature, along with clinical expertise and opinion, was used to draft concise, clinically relevant reviews of the current literature. Based on these reviews, experts developed and voted on recommendations and statements to reflect the practical management of adult patients with AD as a guide for health care providers in Canada and across the globe, using a prespecified agreement cutoff of 75%. RESULTS:: Eleven consensus statements were approved by the expert panel and reflected 4 key domains: pathophysiology, assessment, comorbidities, and treatment. CONCLUSIONS:: These statements aim to provide a framework for the assessment and management of adult patients with AD and to guide health care providers in practically relevant aspects of patient management.

Approach to the Assessment and Management of Adult Patients With Atopic Dermatitis: A Consensus Document. Section II: Tools for Assessing the Severity of Atopic Dermatitis.

Clinicians rely on clinical measures to define the severity of atopic dermatitis and assess outcomes of therapy. These measures can be objective (ie, physician assessments of disease severity) or subjective (ie, patient-reported symptoms and quality of life outcomes). In this review, the most commonly used tools for assessing atopic dermatitis severity in adult patients are presented and compared. These include Eczema Area and Severity Index (EASI); SCORing Atopic Dermatitis (SCORAD); Physician Global Assessment (PGA); body surface area (BSA); Atopic Dermatitis Severity Index (ADSI); Six Area, Six Sign Atopic Dermatitis (SASSAD); Patient Oriented Eczema Measure (POEM); Dermatology Life Quality Index (DLQI); and pruritus Numerical Rating Scale (NRS). Available severity strata for the tools are summarized, although the use of severity strata in clinical practice is not recommended. Since both objective and subjective assessments of disease severity are important to assess, consideration of clinical characteristics such as disease recurrence or persistence, as well as location of the affected areas, should be considered in the overall judgement of disease severity and consideration of therapy choice.

Evaluation of the Physician Global Assessment and Body Surface Area Composite Tool for Assessing Psoriasis Response to Apremilast Therapy: Results from ESTEEM 1 and ESTEEM 2.

BACKGROUND: The Physician Global Assessment and Body Surface Area (PGAxBSA) composite tool is a simple, effective alternative for measuring psoriasis severity. OBJECTIVE: To evaluate the product of PGAxBSA as a sensitive alternative to the Psoriasis Area and Severity Index (PASI) for assessing disease severity and therapeutic response with data collected from the phase 3 ESTEEM 1 and 2 trials. METHODS: This post hoc analysis included 836 patients randomized to apremilast 30 mg BID at baseline (ESTEEM 1, n=562; ESTEEM 2, n=274). Spearman correlation coefficients were used to compare PGAxBSA, PASI, and the Dermatology Life Quality Index (DLQI). Concordance between PGAxBSA and PASI was evaluated for 50%/75%/90% improvement from baseline at week 16. RESULTS: In ESTEEM 1 and 2, PGAxBSA and PASI exhibited significant positive correlations for measuring disease severity at baseline (r≥0.757) and week 16 (r≥0.807). At week 16, ≥79% concordance was observed between PGAxBSA and PASI for 75% and 90% improvement from baseline; greater concordance (>88.0%) was observed using 50% improvement from baseline. At week 16, PGAxBSA and PASI were moderately correlated with DLQI. LIMITATIONS: Analysis was limited to patients with baseline BSA ≥10% and static PGA ≥3. CONCLUSIONS: In patients with moderate to severe psoriasis, PGAxBSA is correlated with PASI and sensitive to therapeutic response.

Assessment of the long-term safety and effectiveness of etanercept for the treatment of psoriasis in an adult population.

BACKGROUND: Etanercept is well tolerated and effective in moderate to severe plaque psoriasis. However, effectiveness and safety data beyond 2.5 years have not been reported. OBJECTIVE: We sought to assess the effectiveness and safety profile of up to 4 years of etanercept therapy in psoriasis. METHODS: We analyzed prospective data from previous trials and open-label extensions, including 506 patients who initiated etanercept therapy in either of two phase III trials. Patients received etanercept, 25 mg twice weekly, 50 mg weekly, or 50 mg twice weekly, depending on which trial therapy was started. Dosage adjustments were allowed in open-label extensions, but no patients exceeded 50 mg twice weekly. Outcomes included change from baseline for the static Physician Global Assessment and Dermatology Life Quality Index scores. Exposure-adjusted adverse event (AE) rates were calculated. RESULTS: In all, 75.9% (95% confidence interval 67.9-84.0) and 27.8% (95% confidence interval 19.3-36.2) maintained Dermatology Life Quality Index response (≥ 5-point improvement from baseline) and static Physician Global Assessment response (clear or almost clear) at 48 months, respectively. AE and serious AE rates were 243.5 and 7.8 events per 100 patient-years, respectively. No serious AE rates exceeded 1.0 event per 100 patient-years. Overall infection and serious infection rates were 96.9 and 0.9 events per 100 patient-years, respectively. No cases of tuberculosis or lymphoma were reported. LIMITATIONS: Effectiveness data were limited to static Physician Global Assessment and Dermatology Life Quality Index scores. Analysis of AE rates was limited to available comparator databases. CONCLUSION: Etanercept demonstrated sustained effectiveness and a favorable safety profile with no cumulative toxicity for up to 4 years, representing, to our knowledge, the longest published study on etanercept use in psoriasis to date.

Safe psoriasis control: a new outcome measure for the composite assessment of the efficacy and safety of psoriasis treatment.

BACKGROUND: PASI is an inadequate outcome measure for the assessment of psoriasis treatments. No currently used endpoints provide a benefit: risk assessment of treatment taking into consideration all available efficacy and safety data. OBJECTIVE: To propose a new outcome measure called "safe psoriasis control" (SPC), which assesses multiple dimensions of the disease in a clinically meaningful way through the combined use of appropriate efficacy, quality of life, and safety data. METHODS: Data from 3,500 subjects were used for the purpose of derivation and validation of the SPC endpoint. Advanced statistical methodology was used to evaluate and validate important components in the assessment of therapeutic benefit. RESULTS: SPC was shown to be a simple but meaningful combined endpoint showing the proportion of patients who had treatment benefit without major side effects. CONCLUSION: The SPC endpoint may be a step-forward in providing a composite tool for the evaluation of treatments for psoriasis.
