Rapid and Sustained Effect of Dupilumab on Work Productivity in Patients with Difficult-to-treat Atopic Dermatitis:Results from the Dutch BioDay Registry

Dupilumab treatment improves signs, symptoms, and quality of life in patients with moderate-to-severe atopic dermatitis. This study evaluated the impact of dupilumab treatment on absenteeism, presenteeism, and related costs in a large multi-centre cohort of adult patients with difficult-to-treat atopic dermatitis in daily practice. Patients treated with dupilumab participating in the Dutch BioDay Registry reporting employment were included. Absenteeism, presenteeism, and related costs at baseline and during follow-up were calculated using the Work Productivity and Activity Impairment questionnaire. A total of 218 adult patients with moderate-to-severe atopic dermatitis were included. Total work impairment reduced significantly from baseline (35.5%) to week 52 (11.5%), p &lt; 0.001. Median weekly productivity losses reduced significantly from baseline (€379.8 (140.7-780.8)) to week 52 (€0.0 (0.0-211.0), p &lt; 0.001). In this study, dupilumab treatment demonstrated a significant improvement in work productivity and reduction in associated costs in a large cohort of patients with difficult-to-treat atopic dermatitis in daily practice.</p

Dupilumab shows long-term effectiveness in a large cohort of treatment-refractory atopic dermatitis patients in daily practice:52-Week results from the Dutch BioDay registry

Background Real-life data on long-term effectiveness and safety of dupilumab in atopic dermatitis patients are limited. Objective To study 52-week effectiveness and safety of dupilumab in a prospective multicenter cohort of adult patients with treatment-refractory atopic dermatitis. Methods Patients treated with dupilumab and participating in the Dutch BioDay registry were included. Clinical effectiveness and safety were evaluated. Results Two hundred ten atopic dermatitis patients were included. Mean percentage change in Eczema Area and Severity Index score after 16 weeks was –70.0% (standard deviation 33.2%) and further decreased to –76.6% (standard deviation 30.6%) by week 52. A greater than or equal to 75% improvement in the score was achieved by 59.9% of individuals by week 16 and by 70.3% by week 52. The most reported adverse effect was conjunctivitis (34%). Limited patients (17; 8.1%) discontinued dupilumab treatment. Limitations Because of the lack of a control group and observational design, factors of bias may have been induced. Conclusion Treatment with dupilumab resulted in a rapid improvement in clinical outcome measures, and effectiveness further improved during the 52-week follow-up period

When does atopic dermatitis warrant systemic therapy? Recommendations from an expert panel of the International Eczema Council

BackgroundAlthough most patients with atopic dermatitis (AD) are effectively managed with topical medication, a significant minority require systemic therapy. Guidelines for decision making about advancement to systemic therapy are lacking.ObjectiveTo guide those considering use of systemic therapy in AD and provide a framework for evaluation before making this therapeutic decision with the patient.MethodsA subgroup of the International Eczema Council determined aspects to consider before prescribing systemic therapy. Topics were assigned to expert reviewers who performed a topic-specific literature review, referred to guidelines when available, and provided interpretation and expert opinion.ResultsWe recommend a systematic and holistic approach to assess patients with severe signs and symptoms of AD and impact on quality of life before systemic therapy. Steps taken before commencing systemic therapy include considering alternate or concomitant diagnoses, avoiding trigger factors, optimizing topical therapy, ensuring adequate patient/caregiver education, treating coexistent infection, assessing the impact on quality of life, and considering phototherapy.LimitationsOur work is a consensus statement, not a systematic review.ConclusionThe decision to start systemic medication should include assessment of severity and quality of life while considering the individual's general health status, psychologic needs, and personal attitudes toward systemic therapies

Serum Creatinine Levels During and After Long-term Treatment with Cyclosporine A in Patients with Severe Atopic Dermatitis

Safety data with respect to kidney function during long-term treatment with cyclosporine A (CsA) in patients with atopic dermatitis is limited. Data on serum creatinine levels before, during and after CsA treatment were collected in a retrospective cohort of adult patients with atopic dermatitis. The median duration of treatment of 150 patients was 280 days (interquartile range 203-528 days). There was a significant, but not clinically relevant, increase in serum creatinine compared with the baseline level after 3 weeks of treatment with CsA and stabilization during the maintenance phase at the group level. Twenty-two (14.7%) patients had a greater than 30% increase in serum creatinine (cut-off point for clinically relevant change) compared with baseline. These patients were significantly older than the patients without a 30% increase (mean ± standard deviation age 41.4 ± 15.6 vs. 33.8 ± 11.7 years (p = 0.01)). During follow-up, all patients had a less than 30% increase in serum creatinine levels compared with baseline levels. At the group level serum creatinine levels during follow-up were not significantly different from baseline

Dupilumab in atopic dermatitis : rationale, latest evidence and place in therapy

Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases. The prevalence of AD is increasing and is currently estimated at 10–20% in adults worldwide. In the majority of patients, AD can be adequately controlled with topical treatment or ultraviolet light therapy, but there is a high unmet need for effective and safe therapeutics in patients with more severe or difficult to treat AD. During the past decade, new advances in the understanding of the underlying immune pathogenesis of AD have led to the development of new, more targeted therapies. Dupilumab, a fully human monoclonal antibody targeting the interleukin (IL)-4 receptor α, thereby blocking the IL-4 and IL-13 pathway, is one of the first biologics that has been developed for AD. Dupilumab has shown promising results in phase III trials and has recently been approved by the US Food and Drug Administration and the European Commission for the treatment of moderate to severe AD. With the approval of dupilumab, we are entering a new era of biological therapeutics in AD management. The place of dupilumab should be established in the current treatment standards. Based on current treatment guidelines and experts’ opinions in the management of AD, we have built a proposal for a treatment algorithm for systemic treatment of AD in European countries
