    Atopic dermatitis (AD) affects 15-20% of children globally and is characterized by chronic skin inflammation and impaired skin barrier.

  • 2

    This study analyzed fecal samples from 53 children with mild-to-moderate AD and 16 healthy controls to investigate gut microbiota and metabolomic profiles.

  • 3

    AD patients showed increased gut microbial richness and distinct β-diversity, with specific genera like Parabacteroides and Klebsiella enriched.

  • 4

    A combined biomarker panel demonstrated promising diagnostic potential with an AUC of 0.941 and accuracy of 84.6%, requiring further validation.

  • 5

    Metabolomic analysis identified 68 differentially accumulated metabolites in AD, primarily linked to lipid and nucleotide metabolism.
