Food allergies are associated with various abnormalities in seemingly-healthy skin in pediatric patients suffering from atopic dermatitis (AD). AD is a common skin disorder also known as eczema that makes the skin turn red and itchy. It is long lasting which tends to flare up periodically.
The surprising findings represent one of the most comprehensive skin-related assessments of AD patients to date, and hint that treatments for AD and food allergy should focus on improving the function of the skin barrier.
Atopic dermatitis is an inflammatory skin disorder that affects nearly 20% of children worldwide, and one-third of AD patients also have food and respiratory allergies. Scientists have sought to better understand the relationship between AD and food allergy, but progress has been limited because skin sampling methods such as biopsies are overly invasive.
Future studies should further examine the complex relationships between S. aureus overgrowth, reduced filaggrin and food allergy sensitization in patients, the authors say.
