Well-recognized tactic for the management of formula-fed children with cow’s milk protein allergy (CMPA) is exclusion of whole cow milk protein and its replacement with extensively hydrolyzed or amino acid formula. One of the most topical issue is the choice of therapeutic formula for a child with CMPA. This article presents information about the clinical manifestations of CMPA and describes the principles of nutrition therapy. All the stages of preparation of adapted therapeutic formula are discussed in detail. It has been shown that the choice of therapeutic formula for a child with CMPA depends on the disease clinical manifestations, their severity, and the presence of comorbid conditions. Current requirements for extensively hydrolyzed formula are reduced to limitations in the size of peptides with immunoreactive properties and indicate the need for evidence of the clinical efficacy of such formula in double-blind placebo-controlled studies.
Background. According to the currently existing hypothesis, epicutaneous sensitization is one of the leading mechanisms in the development of food allergy.The aim of this review was to analyze immune mechanisms in epicutaneous sensitization and the role of skin barrier impairment.We performed a literature search using PubMed, UpToDate, Web of Science, and Scopus databases by the key words: epicutaneous sensitization, atopic dermatitis, skin barrier impairment, food allergy. Articles were to be in open access and present the most relevant information on the topic. Studies were selected by the largest sample size and the highest citation index. Once publications were identified, they were reviewed by all the authors to select the studies that specifically addressed the theme of the review. A total of 101 publications from 1998–2000 were included in the study.This review article discusses the data of experimental studies, sets out modern ideas about the hypothesis of a double exposure to an allergen, and presents research data proving the clinical significance of epicutaneous sensitization in relation to food allergy. Knowledge about the mechanisms of epicutaneous sensitization development is necessary to elaborate strategies for prevention of food allergy. One of the modern trends in prevention is the use of emollients, which are supposed to restore the skin response. However, studies on preventive intake of emollients do not present a similar viewpoint.There is not enough evidence for or against the mechanism of epicutaneous sensitization as an indispensable condition for the formation of food allergies. Further research in this area is required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
