Nutritional Immunity is one of the most ancient innate immune responses, during which the body can restrict nutrients availability to pathogens and restricts their uptake by the gut mucosa (mucosal block). Though this can be a beneficial strategy during infection, it also is associated with non‐communicable diseases—where the pathogen is missing; leading to increased morbidity and mortality as micronutritional...
Background
Food allergy (FA) is an inappropriate immunological response to food proteins resulting from an impaired induction of oral tolerance. Various early environmental factors can affect the establishment of intestinal homeostasis, predisposing to FA in early life. In this context, we aimed to assess the effect of chronic perinatal exposure to food‐grade titanium dioxide (fg‐TiO2), a common...
Background
Food allergy is a leading cause of anaphylaxis worldwide. Allergen‐specific immunotherapy is the only treatment shown to modify the natural history of allergic disease, but application to food allergy has been hindered by risk of severe allergic reactions and short‐lived efficacy. Allergen‐derived peptides could provide a solution. PVX108 comprises seven short peptides representing immunodominant...
Background
The role of prenatal diet on childhood wheezing and subsequent risk of asthma is inconclusive, which may be partly due to the heterogeneity in wheezing phenotypes. We aimed to identify wheeze trajectories in early childhood and to examine their associations with periconceptional maternal diet quality.
Methods
Data from 70,530 mother–child pairs of liveborn singletons from the Japan Environment...
Background
Environmental exposure to peanut through non‐oral routes is a risk factor for peanut allergy. Early‐life exposure to air pollutants, including particulate matter (PM), is associated with sensitization to foods through unknown mechanisms. We investigated whether PM promotes sensitization to environmental peanut and the development of peanut allergy in a mouse model.
Methods
C57BL/6J mice...
Background
Conventional basophil activation tests (BATs) measure basophil activation by the increased expression of CD63. Previously, fluorophore‐labeled avidin, a positively‐charged molecule, was found to bind to activated basophils, which tend to expose negatively charged granule constituents during degranulation. This study further compares avidin versus CD63 as basophil activation biomarkers...
Background
New treatment options with improved safety and novel mechanisms of actions are needed for patients with peanut allergy.
Objectives
To evaluate the safety, tolerability, and immunogenicity of ASP0892, a peanut DNA vaccine, after intradermal (id) or intramuscular (im) administration in adult or adolescent patients with peanut allergy in two phase 1 studies.
Methods
ASP0892 or placebo...
Background
While dysregulated sphingolipid metabolism has been associated with risk of childhood asthma, the specific sphingolipid classes and/or mechanisms driving this relationship remain unclear. We aimed to understand the multifaceted role between sphingolipids and other established asthma risk factors that complicate this relationship.
Methods
We performed targeted LC–MS/MS‐based quantification...
The European Academy of Allergy and Clinical Immunology (EAACI) is updating the Guidelines on Food Allergy Diagnosis. We aimed to undertake a systematic review of the literature with meta‐analyses to assess the accuracy of diagnostic tests for IgE‐mediated food allergy. We searched three databases (Cochrane CENTRAL (Trials), MEDLINE (OVID) and Embase (OVID)) for diagnostic test accuracy studies published...
In 2014, the European Academy of Allergy and Clinical Immunology (EAACI) published the first systematic review that summarized the prevalence of food allergy (FA) and food sensitization in Europe for studies published 2000–2012. However, only summary estimates for tree nut allergy (TNA) were feasible in that work. In the current update of that systematic review, we summarized the prevalence of tree...
