Peanut Allergy News and Research

RSS

A peanut allergy is an overreaction of the body's immune system to peanut protein. All peanut and peanut products must be excluded from the diet. This is one on the most common allergies that leads to anaphylaxis, so it is extremely important that all sources of peanut be avoided.

Breakthrough nano-shield blocks selective allergic reactions

Northwestern University researchers have developed the first selective therapy to prevent allergic reactions, which can range in severity from itchy hives and watery eyes to trouble breathing and even death.

Advancements in food allergy research promise improved diagnosis and treatment options

A review in the Journal of Allergy and Clinical Immunology discusses the global trends in food allergy prevalence, with stabilization in developed regions and an increase in developing countries, alongside advancements in understanding the mechanisms, diagnosis, and treatment of food allergies.

Early intervention with sublingual immunotherapy may lead to remission of peanut allergy

A three-year clinical trial funded by the National Institutes of Health and Food Allergy Research and Education (FARE) has shown that the sublingual immunotherapy, or SLIT, is safe in peanut-allergic children ages 1 to 4, with a greater likelihood of desensitization and remission the earlier the treatment began.

Differences in gut bacteria can be early indicators for the development of peanut allergies

A new study led by researchers at the Icahn School of Medicine at Mount Sinai has revealed key differences in gut bacteria and their metabolic byproducts in infants that may predict the development of peanut allergies by mid-childhood.

Children exposed to air pollution in early years more likely to develop food allergies

A new research paper explores associations between food allergies and pre- or post-natal exposure to pollutants in the air, thus paving the way for future studies on the potential sensitization of the gut by exposure of the skin or airway to pollutants, in addition to the alimentary route.

Novel peanut-specific human IgE monoclonal antibodies may uncover new therapeutic targets for peanut allergy

A recent Frontiers in Immunology journal study by University of North Carolina at Chapel Hill and Vanderbilt University researchers has created an in vitro system to determine potential therapeutics targeting sensitized effector cells based on human, allergen-specific, Immunoglobulin E (IgE) monoclonal antibodies (mAbs).

Microneedle treatments could significantly desensitize people with food allergies

Treating peanut allergy with microneedles could significantly improve desensitization by directly targeting the allergen to the skin, providing greater protection from severe allergic reactions for millions of people, a new study suggests.

Clinical trial shows encouraging results with fecal microbiota transplants for peanut-allergic patients

Peanut allergies are hard to treat and can cause fatal or near-fatal anaphylactic reactions. People usually don't outgrow peanut allergy, requiring lifelong scrutiny of food labels to avoid even small traces of peanut.

New opportunity to induce remission of peanut allergy in young children through oral immunotherapy

A clinical trial funded by the National Institutes of Health has found that giving peanut oral immunotherapy to highly peanut-allergic children ages 1 to 3 years safely desensitized most of them to peanut and induced remission of peanut allergy in one-fifth. The immunotherapy consisted of a daily oral dose of peanut flour for 2.5 years.

Study shows efficacy, safety of oral immunotherapy in one- to three-year-olds with peanut allergy

The majority of young children treated with peanut immunotherapy achieved desensitization after two and a half years of treatment, and one in five remained in remission 26 weeks after treatment ended, according to a randomized controlled trial published in The Lancet.
