Introduction
Dupilumab has recently been approved for the treatment of moderate to severe atopic dermatitis (AD) in adults. Daily practice data on dupilumab treatment are scarce.
Objective
To study ...the effect of 16‐week treatment with dupilumab on clinical response and serum biomarkers in adult patients with moderate‐severe AD in daily practice.
Methods
Data were extracted from the BioDay registry, a prospective multicenter registry. Sixteen‐week clinical effectiveness of dupilumab was expressed as number of patients achieving EASI‐50 (Eczema Area and Severity Index) or EASI‐75, as well as patient‐reported outcomes measures (Patient‐Oriented Eczema Measure, Dermatology Life Quality Index, Numeric Rating Scale pruritus). Twenty‐one biomarkers were measured in patients treated with dupilumab without concomitant use of oral immunosuppressive drugs at five different time points (baseline, 4, 8, 12, and 16 weeks).
Results
In total, 138 patients treated with dupilumab in daily practice were included. This cohort consisted of patients with very difficult‐to‐treat AD, including 84 (61%) patients who failed treatment on ≥2 immunosuppressive drugs. At week 16, the mean percent change in EASI score was 73%. The EASI‐50 and EASI‐75 were achieved by 114 (86%) and 82 (62%) patients after 16 weeks of treatment. The most reported side effect was conjunctivitis, occurring in 47 (34%) patients. During dupilumab treatment, disease severity‐related serum biomarkers (TARC, PARC, periostin, and IL‐22), eotaxin‐1, and eotaxin‐3 significantly decreased.
Conclusion
Treatment with dupilumab significantly improved disease severity and decreased severity‐related serum biomarkers in patients with very difficult‐to‐treat AD in a daily practice setting.
This study evaluated the clinical effectiveness and safety of 16‐weeks of dupilumab treatment in adults with AD. Dupilumab treatment significantly suppressed disease severity‐related serum biomarkers and eosinophil chemokines. By the end of the treatment, the EASI‐50 and EASI‐75 was achieved by 86% and 62% of patients, respectively.

Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects 10 to 20% of children and between 2 and 15% of the adults in Western Europe. Since 2000, therapeutic clothing or functional ...textiles based on silver or chitosan as antibacterial agents were introduced for AD. These agents aim to reduce skin colonization with Staphylococcus (S.) aureus. Increased colonization with S. aureus is correlated with increased AD severity. The antimicrobial effects of silver and chitosan have been demonstrated before. At this point, there is insufficient evidence for the effectiveness of antibacterial therapeutic clothing in patients with AD.
This is a pragmatic randomized controlled double-blind multi-center trial comparing the effectiveness of antibacterial therapeutic clothing based on silver or chitosan as compared with non-antibacterial therapeutic clothing in patients with moderate to severe AD. A total of 165 participants, aged 0 to 80, diagnosed with moderate to severe AD are included. The study is performed in the Erasmus MC University Medical Center, University Medical Center Groningen, University Medical Center Utrecht, Amsterdam University Medical Centers, and St. Antonius Hospital Nieuwegein. Patients will be randomized 1:1:1 into one of the three intervention groups: group A will receive therapeutic clothing without antimicrobial agents, group B will receive microbial growth reducing therapeutic clothing based on chitosan, and group C will receive antimicrobial clothing based on silver. All therapeutic clothing is to be worn at night during the 12-month intervention period. Usual care is continued. The primary objective is to assess the effectiveness of antibacterial clothing (silver and chitosan group) as compared to non-antibacterial clothing assessed with the Eczema Area and Severity Index at 12 months compared to baseline. Secondary outcomes include between-group differences in physician- and patient-reported outcome measures, topical therapy use, S. aureus skin colonization, and safety. Data will be collected at baseline and after 1 month, 3 months, 6 months, and 12 months. A cost-effectiveness analysis will be performed.
This trial will provide data on the effectiveness, cost-effectiveness, and safety of antibacterial therapeutic clothing for patients with AD.

Long-term daily practice data on patient-reported benefits of dupilumab for atopic dermatitis (AD) remains limited.
To evaluate patient-reported outcome measures (PROMs) and the safety of dupilumab ...in patients with moderate-to-severe AD over a follow-up period of up to 5 years.
Data were extracted from the prospective, multicenter BioDay registry (October 2017–2022) of patients with moderate-to-severe AD treated with dupilumab in daily practice.
In total 1223 patients, 1108 adults and 115 pediatric patients were included. After ≥1 year of treatment, mean Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), Numeric rating scale (NRS)-pruritus ranged between 7.8 and 8.7, 3.5 and 4.2, and 2.9 and 3.1 in adults, respectively, whilst these patient-reported outcome measures (PROMs) ranged between 8.9 and 10.9, 4.4 and 6.4, and 3.0 and 3.7 in pediatric patients, respectively. At follow-up, overall work impairment decreased from 40.1% to 16.3% to 13.3% in adults. Furthermore, class I obesity and itch-dominant patients generally had less favorable treatment response. Of all patients, 66.8% reported ≥1 adverse event, with conjunctivitis being the most common (33.7%).
The overall percentage of missing values for selected PROMs was 26% in adults and 46% in pediatric patients.
In addition to favorable safety, dupilumab has demonstrated sustained effectiveness across various PROMs, underscoring the treatment benefits from patients' perspectives.
