Scratching the skin triggers a series of immune responses culminating in an increased number of activated mast cells—immune cells involved in allergic reactions—in the small intestine, according to research conducted in mice. This newly identified skin-gut communication helps illuminate the relationship between food allergy and atopic dermatitis (a type of eczema), a disease characterized by dry, itchy skin.

Atopic dermatitis, a common inflammatory skin condition also known as allergic eczema, affects nearly 20 percent of children, 30 percent of whom develop food allergies. Scientists have now found that children with both atopic dermatitis and food allergy have structural and molecular differences in the top layers of healthy-looking skin near the eczema lesions, whereas children with atopic dermatitis alone do not.
New research suggests that the gut microbiome may help prevent the development of cow’s milk allergy. Scientists at the University of Chicago found that gut microbes from healthy human infant donors transplanted into mice protected animals exposed to milk from experiencing allergic reactions, while gut microbes transplanted from infants allergic to milk did not. The work, described online today in Nature Medicine, was supported in part by NIH’s National Institute of Allergy and Infectious Diseases.
The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and Children’s National Health System, a pediatric academic medical center in Washington, D.C., have launched a clinical research partnership devoted to treating and preventing allergic, immunologic and infectious diseases in children. An inaugural symposium will take place at Children’s National on Sept. 17, 2018, to highlight the partnership and discuss current and future directions for its research activities.
Scientists have discovered that the absence of a specific protein in cells lining the esophagus may cause inflammation and tissue damage in people with eosinophilic esophagitis (EoE). EoE affects as many as 150,000 people in the United States, many of whom are children. People with EoE experience difficult or painful swallowing, vomiting and nutritional problems because an accumulation of immune cells called eosinophils scars the esophagus.
Combining a 16-week initial course of the medication omalizumab with oral immunotherapy (OIT) greatly improves the efficacy of OIT for children with allergies to multiple foods, new clinical trial findings show. After 36 weeks, more than 80 percent of children who received omalizumab and OIT could safely consume two-gram portions of at least two foods to which they were allergic, compared with only a third of children who received placebo and OIT.
While rare, some people experience recurrent episodes of anaphylaxis—a life-threatening allergic reaction that causes symptoms such as the constriction of airways and a dangerous drop in blood pressure—for which the triggers are never identified. Recently, researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, found that some patients’ seemingly inexplicable anaphylaxis was actually caused by an uncommon allergy to a molecule found naturally in red meat.
The National Institutes of Health intends to award $42.7 million over seven years to the Consortium of Food Allergy Research (CoFAR) so it may continue evaluating new approaches to treat food allergy. Established in 2005, the CoFAR has been continuously funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH. The first year of funding has been awarded, and awards will be made in subsequent years based on the availability of funds.
An expert panel sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, issued clinical guidelines today to aid health care providers in early introduction of peanut-containing foods to infants to prevent the development of peanut allergy.
A wearable patch that delivers small amounts of peanut protein through the skin shows promise for treating children and young adults with peanut allergy, with greater benefits for younger children, according to one-year results from an ongoing clinical trial. The treatment, called epicutaneous immunotherapy or EPIT, was safe and well-tolerated, and nearly all participants used the skin patch daily as directed.
Nearly 80 percent of peanut-allergic preschool children successfully incorporated peanut-containing foods into their diets after receiving peanut oral immunotherapy (OIT), a clinical trial has found. Peanut OIT involves eating small, gradually increasing amounts of peanut protein daily.
Introducing peanut-containing foods during infancy as a peanut allergy prevention strategy does not compromise the duration of breastfeeding or affect children’s growth and nutritional intakes, new findings show. The work, funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is published online on June 10 in the Journal of Allergy and Clinical Immunology.
The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is seeking public comment on a draft update to the 2010 Guidelines for the Diagnosis and Management of Food Allergy in the United States (link is external) to address the prevention of peanut allergy.
The benefits of regularly consuming peanut-containing foods early in life to prevent the development of peanut allergy persist even after stopping peanut consumption for one year, new clinical trial findings show.
Oral immunotherapy for peanut allergy induces early, distinct changes in immune T-cell populations that potentially may help researchers determine which people will respond well to the therapy and which immune mechanisms are involved in the response, a new study suggests.
