Since 2000 therapeutic clothing or functional textiles based on silver or chitosan as antibacterial agents were introduced as therapeutics of atopic dermatitis (AD). These agents aim to reduce skin colonization with Staphylococcus (S.) aureus. S. aureus induces further dysregulation of the inflammatory process and increased colonization with S. aureus is correlated with increased AD severity. Based on the theoretical mode of action and clinical experience, we assume a higher effectiveness of antimicrobial therapeutic clothing compared to control therapeutic clothing on reducing AD severity. The goal of this study is to assess the effectiveness of antibacterial clothing based on silver or chitosan on the doctor-reported AD severity in patients with moderate to severe AD. Secondary goals are to retrieve information about the effect of antimicrobial clothing on clinical symptoms, quality of life, S. aureus colonization, AD medication use and the satisfaction regarding the clothing.
This is a multi-center, double-blind, randomized controlled trial. Patients will be randomized in a 1:1:1 fashion to either therapeutic clothing without antimicrobial agents, antimicrobial therapeutic clothing based on chitosan or antimicrobial clothing based on silver for 12 months.

DermaCura® antimicrobial therapeutic clothing (D\&M) consists of 98% TENCEL® and 2% elastane. 1% chitosan has been added to TENCEL® The therapeutic clothing is to be worn at night during the 12-month intervention period and if needed during the day. Usual care including application of emollients, corticosteroid ointments or creams only if needed and/or antihistamines is continued, with standardized steroid ointments and treatment regimens for comparability purposes.
The Binamed® antimicrobial therapeutic clothing (BAP Medical) consists of micro-modal, lycra and woven silver filaments as antibacterial agent. The therapeutic clothing is to be worn at night during the 12-month intervention period and if needed during the day. Usual care including application of emollients, corticosteroid ointments or creams only if needed and/or antihistamines is continued, with standardized steroid ointments and treatment regimens for comparability purposes.
The Binamed® therapeutic clothing without antimicriobial agents (BAP Medical) is therapeutic clothing made of micro-modal and lycra. Micro-madal is a semi-synthetic wood cellulose fiber. This fiber has a high strength hand elasticity, a high moisture-permeability and feels soft. Lycra ensures an optimal fit on the skin. The therapeutic clothing is to be worn at night during the 12-month intervention period and if needed during the day. Usual care including application of emollients, corticosteroid ointments or creams only if needed and/or antihistamines is continued, with standardized steroid ointments and treatment regimens for comparability purposes.
