Introduction: The pathogenesis of atopic diseases is highly complex, and the exact mechanisms leading to atopic dermatitis (AD) onset in infants remain mostly enigmatic. In addition to an interdependent network of components of skin development in young age and skin barrier dysfunction underlying AD development that is only partially understood, a complex interplay between environmental factors and lifestyle habits with skin barrier and immune dysregulation is suspected to contribute to AD onset. This study aims to comprehensively evaluate individual microbiome and immune responses in the context of environmental determinants related the risk of developing AD in the first 4 years of a child's life.

Article Synopsis
  • The study explores the limitations of DNA-based microbiome analysis, particularly regarding the inability to distinguish between live and dead microorganisms.
  • A Benzonase-based approach (BDA) was tested, which effectively digests DNA from dead cells, thus providing a clearer picture of the living microbiome in skin samples.
  • The findings suggest that while BDA improves the accuracy of living microbiota assessments and reduces host DNA interference, it does not completely eliminate bias from low biomass samples.

Vitiligo ist eine erworbene Hauterkrankung, an der weltweit 0,5 % der Bevölkerung erkranken und die eine große Herausforderung in der dermatologischen Versorgung darstellt.
