Background
Immediate drug hypersensitivity reactions (IDHRs) to clavulanic acid (CLV) have increased in the last decades due to a higher consumption alongside amoxicillin (AX). Due to its chemical instability, diagnostic procedures to evaluate IDHRs to CLV are difficult, and current in vitro assays do not have an optimal sensitivity. The inclusion of the specific metabolites after CLV degradation,...
Background
The use of eliciting doses (EDs) for food allergens is necessary to inform individual dietary advice and food allergen risk‐management. The Eliciting Dose 01 (ED01) for milk and egg, calculated from populations of allergic subjects undergoing oral food challenges (OFCs), are 0.2 mg total protein. The respective Eliciting Dose 05 (ED05) is 2.4 mg for milk and 2.3 mg for egg. As about 70%...
Background
The most recognizable phenotype of severe asthma comprises people who are blood eosinophil and FeNO‐high, driven by type 2 (T2) cytokine biology, which responds to targeted biological therapies. However, in many people with severe asthma, these T2 biomarkers are suppressed but poorly controlled asthma persists. The mechanisms driving asthma in the absence of T2 biology are poorly understood...
Background
Polymerized allergens conjugated to non‐oxidized mannan (PM‐allergoids) are novel vaccines targeting dendritic cells (DCs). Previous experimental data indicate that PM‐allergoids are readily taken up by DCs and induce Treg cells. This first‐in‐human study was aimed to evaluate safety and to find the optimal dose of house dust mite PM‐allergoid (PM‐HDM) administered subcutaneously (SC)...
The worldwide use of COVID‐19 vaccines has shown that immediate allergic reactions to the ingredients are rare but should be clarified by means of an allergological work‐up. This review aims to highlight the current state of knowledge and possible pathogenesis based on the literature published to date. In addition to recording a detailed history and performing skin tests, cellular tests (basophil...
Background
Lipopolysaccharide‐responsive beige‐like anchor protein (LRBA) deficiency and cytotoxic T‐lymphocyte protein‐4 (CTLA‐4) insufficiency are recently described disorders that present with susceptibility to infections, autoimmunity, and lymphoproliferation. Clinical and immunological comparisons of the diseases with long‐term follow‐up have not been previously reported. We sought to compare...
Background
IgE‐epitope profiling can accurately diagnose clinical peanut allergy.
Objective
We sought to determine whether sequential (linear) epitope‐specific IgE (ses‐IgE) profiling can provide probabilities of tolerating discrete doses of peanut protein in allergic subjects undergoing double‐blind, placebo‐controlled food challenges utilizing PRACTALL dosing.
Methods
Sixty four ses‐IgE antibodies...
Background
Allergy to dogs affects around 10% of the population in developed countries. Immune therapy of allergic patients with dog allergen extracts has shown limited therapeutic benefit.
Methods
We established a mouse model of dog allergy by repeatedly administering dog dander and epithelium extracts via the intranasal route. We also assessed the efficacy of a recombinant multimeric protein...
Background
Nontypeable Haemophilus influenzae (NTHi) is a respiratory tract pathobiont that chronically colonizes the airways of asthma patients and is associated with severe, neutrophilic disease phenotypes. The mechanism of NTHi airway persistence is not well understood, but accumulating evidence suggests NTHi can persist within host airway immune cells such as macrophages. We hypothesized that...
Background
Different treatments exist for allergic rhinitis (AR), including pharmacotherapy and allergen immunotherapy (AIT), but they have not been compared using direct patient data (i.e., “real‐world data”). We aimed to compare AR pharmacological treatments on (i) daily symptoms, (ii) frequency of use in co‐medication, (iii) visual analogue scales (VASs) on allergy symptom control considering...
Background
The immunological changes underpinning acquisition of remission (also called sustained unresponsiveness) following food immunotherapy remain poorly defined. Limited access to effective therapies and biosamples from treatment responders has prevented progress. Probiotic peanut oral immunotherapy is highly effective at inducing remission, providing an opportunity to investigate immune changes...
Background
Asthma is one of the most common chronic diseases in childhood, and the prevalence has been increasing over the past few decades. One of the most consistent epidemiological findings is that children living in a farming or rural environment are protected from development of asthma and allergies, but the protective factors in rural China are not clear.
Methods
A community‐based, cross‐sectional...
