| Study Title | Gut sphingolipid metabolites in infants with atopic dermatitis associated with food allergy - Part 2 |
| Study Summary | This study determines sphingolipids and diacylglycerols from infant feces to explore the lipid changes with food allergy in atopic dermatitis. Food allergy (FA) may be present in the range of 20–80% in atopic dermatitis (AD). Food sensitization through the skin can cause FA due to damage to the skin barrier, and failure to acquire tolerance to food allergens in the gut can equally cause the development of FA. Gut metabolites can influence the physical gut barrier and intestinal homeostasis. Therefore, it is possible that gut metabolites related to gut immunity play an important role in the development of FA. Sphingolipids are key factors in cell inflammatory response and affect gut epithelial cells and skin barrier integrity and function. FA is associated with a marked decrease in serum sphingolipid levels. However, there are no reports of FA-associated gut sphingolipid metabolites in infants by targeted metabolomics. In our previous study, we showed that when FA is present in various phenotypes of AD in early life, it might be associated with the later development of asthma. The discovery of a biomarker that can distinguish the phenotypes that accompany AD and FA from other AD phenotypes is therefore expedient. Consequently, we aimed to investigate whether FA in AD infants. can be classified as gut sphingolipid metabolites using targeted metabolomics. |
