Therapeutic Efficacy of Cutaneous Application of Postbiotic N-(1-carbamoyl-2-phenyl-ethyl) Butyramide (FBA) in Pediatric Subjects Affected by Atopic Dermatitis
- Conditions
- Atopic Dermatitis
- Registration Number
- NCT07016087
- Lead Sponsor
- Federico II University
- Brief Summary
Atopic dermatitis (AD) is a chronic, multifactorial inflammatory skin disease characterized by eczematous skin and pruritus and it's due to an alteration of the skin barrier and of the intestinal and skin microbiome (SM), which normally contributes to maintaining skin integrity and modulating host inflammatory responses. This alteration leads to a lower production of butyrate, a short-chain fatty acid capable of reducing skin permeability by improving barrier integrity, performing a trophic effect on the skin and suppressing local inflammatory responses. Furthermore, a reduction of butyrate in patients with AD has also been demonstrated at the intestinal level.
Conventional therapy for AD consists of eliminating exacerbating factors, applying emollients and in exacerbations, or in moderate/severe forms, applying topical steroids or topical calcineurin inhibitors. The possibility of using emollients containing substances physiologically present in the skin, such as butyrate, could represent a safe treatment strategy, capable of reducing exacerbations and therefore the evolution towards moderate-severe forms of AD.
On the basis of these premises, the BuPad study aims to evaluate the therapeutic efficacy of the cutaneous application of a butyrate releaser, the postbiotic N-(1-carbamoyl-2-phenyl-ethyl) butyramide (FBA) in a cosmetic formulation, in children affected by AD.
