Potential role of reduced environmental UV exposure as a driver of the current epidemic of atopic dermatitis

Abstract: The basis for the sudden and dramatic increase in atopic dermatitis (AD) and related atopic diseases in the second half of the 20th century is unclear. The hygiene hypothesis proposes that the transition from rural to urban living leads to reduced childhood exposure to pathogenic microorganisms. Hence instead of having the normal TH1 bias and immune tolerance because of repeated exposure to pathogens, urban dwellers have TH2 cell immune activity and atopic disease in a more sterile environment. Various other e… Show more

“…Hence, small peptide inhibitors of PAR2 could yet enter the therapeutic armamentarium for AD. Because reduced exposure to the benefits of suberythemogenic UV-B has been proposed as a key factor in the recent, urban resurgence of AD [45], it would seem prudent to recommend moderate amounts of exposure to ambient UV-B as a part of the management plan for AD patients. Finally, not only PPAR activators [46], but also several bioflavonoid ingredients, such as hesperidin and apigenin [47], have been shown to boost filaggrin production, and could therefore prove useful in those AD patients who do not exhibit double-allele mutation in Filaggrin gene expression.…”

“…Ево-люційні зміни в структурі та функції шкіри, імовір-ніше, пояснюють підвищений рівень циркулюючого 25(ОН)D 3 у крові жителів Північної Європи. Опи-сано суттєвий зв'язок генетичних факторів струк-тури епідермісу та вітамін-D-статусу, що корелює зі здатністю людини генерувати вітамін D під дією ультрафіолетового опромінення протягом літніх мі-сяців [16].…”

“…Крім того, запалення шкіри, що спостерігається у хворих на АД, знижує рівень філагрину, особливо взимку [9]. Отже, зниження сонячного випромінювання взимку в поєднанні з вологістю і запаленням у шкі-рі, слугує приводом гідролізації філагрину і може пояснити зниження ефекту FLG-мутацій протягом зими [4,16].…”
