Clinical Factors Associated with Peanut Allergy in a High Risk Infant Cohort.

BACKGROUND: Prognostication of peanut allergy (PNA) is relevant for early interventions. We aimed to determine baseline parameters associated with development of PNA in 3-15 month olds with likely egg and/or milk allergy, and/or moderate-severe atopic dermatitis (AD) and a positive egg/milk skin prick test (SPT), but no known PNA. METHODS: The primary endpoint was PNA […]

Food allergy endotype with high risk of severe anaphylaxis in children-Monosensitization to cashew 2S albumin Ana o 3.

BACKGROUND: Food allergy in children can be life-threatening. Component-resolved diagnostics approach to food anaphylaxis is rarely assessed in children. The aim of the study was to identify the food allergen components as the triggers responsible for severe anaphylaxis, with regard to characteristics and associated risks, among children in a large, population-based setting. METHODS: Two hundred […]

The functional biology of peanut allergens and possible links to their allergenicity

Peanut is one of the most common food triggers of fatal anaphylaxis worldwide although peanut allergy affects only 1-2% of the general population. Peanuts are the source of highly potent allergenic proteins. It is emerging that the allergenicity of certain proteins is linked to their biological function. Peanut is an unusual crop in that it flowers above […]

Chemically modified peanut extract shows increased safety while maintaining immunogenicity.

BACKGROUND: Peanuts are most responsible for food-induced anaphylaxis in adults in developed countries. An effective and safe immunotherapy is urgently needed. The aim of this study was to investigate the immunogenicity, allergenicity and immunotherapeutic efficacy of a well characterized chemically modified peanut extract (MPE) adsorbed to Al(OH)3. METHODS: Peanut extract (PE) was modified by reduction […]

Oral peanut immunotherapy‐How much is too much? How much is enough?.

Efficacy of Food allergy immunotherapy (FA-AIT) for cow's milk, hen's egg and peanut at the level of desensitization is established via several small placebo-controlled trials and a number of open label trials1 . First approved treatments for peanut allergy are projected to become available soon including oral immunotherapy (OIT). But there is still a discussion which group of patients might […]

Peanut allergy–individual molecules as a key to precision medicine.

Peanut allergy is one of the most severe food allergies affecting millions of individuals worldwide. In German-speaking countries, peanutallergy is the most important cause of anaphylaxis in children and adolescents. This Editorial highlights the impact of individual peanutallergens on the severity of symptoms and summarizes the allergens' biological characteristics and usefulness as tools for precision diagnostic tests.

" To Screen or not to Screen": Comparing the Health and Economic Benefits of Early Peanut Introduction Strategies in Five Countries.

BACKGROUND: Early peanut introduction (EPI) in the first year of life is associated with reduced risk of developing peanut allergy in children with either severe eczema and/or egg allergy. However, EPI recommendations differ among countries with formal guidelines. METHODS: Using simulation and Markov modeling over a 20-year horizon to attempt to explore optimal EPI strategies […]

Diagnostic accuracy, risk assessment, and cost‐effectiveness of component‐resolved diagnostics for food allergy: a systematic review.

BACKGROUND: Component-resolved diagnostics (CRD) are promising tools for diagnosing food allergy, offering the potential to determine specific phenotypes and to develop patient-tailored risk profiles. Nevertheless, the diagnostic accuracy of these tests varies across studies; thus, their clinical utility remains unclear. Therefore, we synthesized the evidence from studies investigating the diagnostic accuracy, risk assessment ability, and […]

Prediction of the severity of allergic reactions to foods.

BACKGROUND: There is currently considerable uncertainty regarding what the predictors of the severity of diagnostic or accidental food allergic reactions are, and to what extent the severity of such reactions can be predicted. OBJECTIVE: To identify predictors for the severity of diagnostic and accidental food allergic reactions and to quantify their impact. METHODS: The study […]
