Washed microbiota transplantation relieves atopic dermatitis via gut-skin microbiome rebalancing.

ABSTRACT:

Background

Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease in which dysbiosis of gut and skin microbiota contributes to pathogenesis and severity. Washed microbiota transplantation (WMT)-an improved form of fecal microbiota transplantation with enhanced safety and microbiota quality control-has shown efficacy in a single reported adolescent case. However, clinical data on WMT in AD and its effects on the skin and gut microbiota remain limited.

Methods

Twenty-three patients with moderate-to-severe AD received at least two courses of WMT between January 2022 and December 2023. Disease activity was evaluated using the SCORing Atopic Dermatitis (SCORAD) index, the Eczema Area and Severity Index (EASI), the Numeric Rating Scale (NRS) for itch, and the Der
