Investigating the skin microbiome in patients with atopic dermatitis receiving systemic therapy

Official title: Identification of Skin-associated Microbiota in Atopic Dermatitis Patients Undergoing Systemic Therapy

Run by Charite University, Berlin, Germany · NCT05099315 · Data updated 2026-11-12

This study looks at how the skin bacteria of people with moderate to severe atopic dermatitis change while they are on systemic treatments to see if it can help improve their care and understanding of the condition.

What this trial studies

This observational study aims to explore how the skin microbiome changes in patients with moderate to severe atopic dermatitis undergoing systemic therapy, such as biologics or Janus kinase inhibitors. Patients will be monitored over two years with routine examinations every quarter, including blood and skin microbiome sampling. The study seeks to generate new hypotheses regarding the pathogenesis of atopic dermatitis and develop objective scales for assessing disease severity. By understanding these changes, the research could lead to improved therapeutic strategies and disease management.

Why it matters

Potential benefit: If successful, this study could enhance the understanding and management of atopic dermatitis, leading to better treatment options for patients.

How similar studies have gone: While the specific approach of this study is exploratory, similar studies have shown promise in understanding the role of the microbiome in skin conditions.
