The long-term effect of dupilumab on chronic hand eczema in patients with moderate to severe atopic dermatitis:52 week results from the Dutch BioDay Registry

Background: The hands are a common predilection site of atopic dermatitis (AD). Dupilumab is licensed for the treatment of AD but not for chronic hand eczema (CHE), while CHE is challenging to treat. Objectives: To evaluate the long-term effect of dupilumab on hand eczema (HE) in patients with AD from the BioDay Registry. Methods: A prospective observational study of adult patients with HE, treated for AD with dupilumab. Patients with a HE severity of at least moderate at baseline were considered for analysis. Patients with other concomitantly systemic immunosuppressive treatments were excluded. Clinical effectiveness on HE severity, using the Hand Eczema Severity Index (HECSI) and photographic guide, and health-related quality of life, using the Quality of Life in Hand Eczema Questionnaire (QOLHEQ), were evaluated. Results: A total of 72 patients were included. HECSI-75 was achieved by 54/62 patients (87.1%) and HECSI-90 by 39/72 (62.9%) at 52 weeks. Based on the photographic guide, 56/62 patients (90.3%) achieved the endpoint of ‘clear’ or ‘almost clear’. Mean QOLHEQ reduction was −63.5% (95% confidence interval −38.23 to −27.41). There was no difference in response between HE subtypes. Conclusions: The results from this study hold promise for dupilumab to be a suitable treatment option for isolated CHE

Effect of dupilumab on hand eczema in patients with atopic dermatitis:An observational study

Systemic treatment options for chronic hand eczema are limited. Dupilumab is used in atopic dermatitis (AD) but is not licensed for (isolated) hand eczema. In this observational prospective study we aimed to determine the response of hand eczema to dupilumab in patients with AD. Adult patients with hand eczema and AD received dupilumab s.c. at a 600 mg loading dose, followed by 300 mg every 2 weeks. Primary outcome was a minimum improvement of 75% on the Hand Eczema Severity Index after 16 weeks (HECSI-75). Secondary outcomes were severity, measured using the Photographic guide; quality of life improvement as patient-reported outcome, measured using the Dermatology Life Quality Index (DLQI); and AD severity, measured using the Eczema Area and Severity Index (EASI). Forty-seven patients were included (32 males; mean age, 45 years). HECSI-75 was achieved by 28 (60%). Mean HECSI score reduction was 49.2 points (range, 0-164; 95% within-subject confidence interval, 46.4-52.0), which was already significantly decreased after 4 weeks (P < 0.001). DLQI score mean improvement was 8.8 points (standard deviation [SD], 6.0) or 70.0% decrease (SD, 26.4) (P < 0.001). Eighteen patients (38%) were classified as responders on the Photographic guide. There was no difference in response between chronic fissured and recurrent vesicular clinical subtypes. Similar percentages of patients achieving EASI-75 and HECSI-75 were seen after 16 weeks. In conclusion, this study shows a favorable response of hand eczema to dupilumab in patients with AD. This raises the question whether a response will also be seen in isolated hand eczema

Nomenclature and clinical phenotypes of atopic dermatitis

Atopic dermatitis is a heterogeneous disease and resists classification. In this review, we discuss atopic dermatitis nomenclature and identify morphologic phenotypes, which will facilitate correct diagnoses and development of treatment strategies. We support using the term 'atopic dermatitis' rather than eczema, because it describes the allergic background and inflammation ('itis') as drivers of the disease. Atopic dermatitis has many morphologic manifestations that vary by topographic area affected, age, or race and require consideration in differential diagnosis. Different phenotypes based on morphology and topographic location, ethnicity, and age are discussed. A better-defined phenotype identification for atopic dermatitis will facilitate earlier and correct diagnosis of this complex condition and inform selection of the most appropriate treatment choice in an era in which targeted therapies may generate more individualized patient care

Efficacy of Dupilumab in Atopic Dermatitis : The Patient's Perspective

Atopic dermatitis (AD), a predominantly type 2 inflammatory skin disease, affects approximately 2-5% of adults, with a high burden of disease. In moderate-to-severe AD, lesions can be extensive and pruritus intense with patients experiencing skin pain, sleep and mental health disturbances, and diminished quality of life (QoL). The objective of this study was to evaluate the efficacy of dupilumab for the treatment of AD from the patients' perspective using patient-reported outcome data from four clinical trials (CHRONOS, SOLO 1&2, and CAFÉ) in patients (N = 1553) receiving either the approved 300 mg q2w dupilumab with/without topical corticosteroids (TCS) dose or control (placebo or placebo + TCS). Patient Global Assessment of Disease Status (PGADS) was used to measure patients' well-being and Patient Global Assessment of Treatment Effect (PGATE) was used to measure treatment efficacy. Patients were asked "Considering all the ways in which your eczema affects you, indicate how well you are doing" to assess their perception of well-being and "How would you rate the way your eczema responded to the study medication?" to assess their perception of treatment effect. Possible responses for both metrics included poor, fair, good, very good, and excellent. In all four studies, a significantly higher proportion of dupilumab-treated patients reported "Good"/"Very Good"/"Excellent" disease status from week 2 through study end versus control (CHRONOS, 52 weeks: 69.8% vs. 25.1%; SOLO 1&2, 16 weeks: 59.5% vs. 24.6%; CAFÉ, 16 weeks: 84.1% vs. 45.4%; all P < 0.0001), and significantly more dupilumab-treated patients reported "Good"/"Very Good"/"Excellent" treatment efficacy versus control (CHRONOS: 72.6% vs. 24.8%; SOLO 1&2: 65.0% vs. 21.1%; CAFÉ, 16 weeks: 85.0% vs. 36.1%; all P < 0.0001). Adult patients with AD perceived that dupilumab with/without concomitant TCS was highly efficacious and improved overall disease status and well-being as early as week 2 and throughout treatment periods up to 1 year.

Eczema control and treatment satisfaction in atopic dermatitis patients treated with dupilumab - a cross-sectional study from the BioDay registry

Background Eczema control is a new construct to be measured in atopic dermatitis (AD). Objectives Measuring patient-perceived eczema control and treatment satisfaction in AD patients, treated with dupilumab between 16 and 52 weeks. Methods Cross-sectional questionnaire study. Patients from the Dutch BioDay registry completed the Atopic Dermatitis Control Test (ADCT), Recap of Atopic Eczema (RECAP) and Treatment Satisfaction Questionnaire for Medication, Version II (TSQM v. II), along with other Patient Reported Outcome Measures (PROMs). Results 104/157 patients responded (response rate 66.2%). Median ADCT score was 4 (interquartile range [IQR] 5); median RECAP score was 5 (IQR 6); median TSQM v.II global satisfaction score was 83.3 (IQR 25.0). According to the ADCT, 38.5-66.3% perceived their AD was 'in control', depending on the interpretability method used. Minimally clinically important difference (MCID) of >= 4 points for the DLQI and POEM was achieved respectively in N = 66 (84.6%) and N = 63 (78.8%) patients. Conclusion When considering the favorable scores on other PROMs and the TSQM v. II, and comparing these to the relatively low percentage of patients perceiving control according to the ADCT, interpretability of eczema control still appears difficult. Treatment satisfaction in the studied cohort was high

Use of systemic therapies in adults with atopic dermatitis:12-month results from the European prospective observational study in patients eligible for systemic therapy for atopic dermatitis (EUROSTAD)

Background The European Prospective Observational Study in Patients Eligible for Systemic Therapy for Atopic Dermatitis (EUROSTAD) is an ongoing observational study aiming to describe characteristics of patients with atopic dermatitis (AD) treated with systemic therapy over time and the management of their disease in a real-world setting. Methods Data from patients enrolled in EUROSTAD between March 2017 and April 2019 were analyzed for systemic therapy use and treatment change over 12 months. Results 288 patients reported taking systemic medications; 42.7% received cyclosporine, 35.3% dupilumab, 28.1% methotrexate, 25.4% oral corticosteroids, 6.8% azathioprine, 6.1% injectable corticosteroids, and 3.4% mycophenolate. The median duration of treatment was 1.1 months for oral systemic corticosteroids, 3.2 months for injectable corticosteroids, 4.8 months for cyclosporine, 7.3 months for methotrexate, and 14.9 months for dupilumab. The most frequent reasons for stopping treatment included lack of efficacy, patient decision, adverse events, and disease well controlled. Conclusion The 12-month interim EUROSTAD study analysis highlights the current trends and outcomes of systemic treatments for moderate-to-severe AD. Among all systemic treatments for AD, dupilumab was the least likely to be discontinued, whereas cyclosporine and corticosteroids, whilst effective, were primarily limited to episodic flare management consistent with treatment guidelines

The patient-reported disease burden in adults with atopic dermatitis : a cross-sectional study in Europe and Canada

Cross-sectional data on patient burden in adults with atopic dermatitis () from real-world clinical practice are limited. This study compared patient-reported burden associated with adult across severity levels from clinical practices in Canada and Europe. This study included adults (18-65 years) diagnosed with by dermatologists, general practitioners or allergists. Participants categorized as mild (n = 547; 37.3%), moderate (n = 520; 35.4%) or severe (n = 400; 27.3%) based on Investigator's Global Assessment completed a questionnaire that included pruritus and pain numerical rating scales, Patient-Oriented-Scoring of Atopic Dermatitis (PO-SCORAD) itch and sleep visual analogue scales, Dermatology Life Quality Index (), and the Hospital Anxiety and Depression Scale (HADS). Participants were also stratified by inadequate efficacy/intolerance/contraindication to cyclosporine [Cyclo; n = 62 (4 mild, 18 moderate, 40 severe)] and any systemic immunomodulatory agent [; n = 104 (13 mild, 31 moderate, 60 severe)] and compared with the severe group excluding participants identified as Cyclo/. Age was similar across severity groups; the proportion of women was higher in the mild group relative to severe (61.2% vs. 50.5%; P < 0.001). Compared with moderate and mild, participants with severe had more comorbidities, higher itch and pain severity, worse sleep and higher levels of anxiety and depression (all P < 0.001). Mean ± score among participants with severe (16.2 ± 6.9) showed a large effect on quality of life that was higher than those with moderate (10.2 ± 6.3) and mild (5.5 ± 4.9) (both P < 0.001). The burden among Cyclo and subgroups was generally similar to that of participants with severe . Adults with reported a substantial burden across multiple domains that was significantly higher in those with severe disease. The burden among participants in the Cyclo/ subgroups was similar to those with severe
