Proposal for an Algorithm on the management of Chronic Rhinosinusitis
AbstractManagement algorithms are traditionally based on phenotypes of disease. In chronic rhinosinusitis (CRS) the most predominant phenotyping has been of the division between "with nasal polyps" (CRSwNP) and "without nasal polyps (CRSsNP) (1). A significant proportion of the available evidence has focussed on this division (1). In the western world this classification of phenotypes roughly corresponds with the most prominent endotypes, with CRSwNP mainly being Th2 and CRSsNP more often...

Vagus Nerve Stimulation dampens intestinal inflammation in a murine model of experimental Food Allergy
AbstractBackgroundThe vagus nerve has emerged as an important modulator of the intestinal immune system. Its anti‐inflammatory properties have been previously shown in innate and Th1/Th17 predominant inflammatory models. To what extent the vagus nerve is of importance in Th2 inflammatory responses like food allergy is still unclear. In this study we therefor aimed to investigate the effect of vagotomy (VGX) and vagus nerve stimulation (VNS), on the development and severity of experimental...

Hypoallergenicity of a whey‐based, extensively hydrolyzed infant formula prepared with non‐porcine enzymes
AbstractIn formula‐fed infants, extensively hydrolyzed formula (EHF) is considered the first‐line treatment of cow's milk protein allergy (CMPA).1 The American Academy of Pediatrics (AAP) defines an EHF to be 'hypoallergenic' if at least 90% of infants with CMPA tolerate it under double‐blind, placebo‐controlled conditions.2 The protein hydrolysis process for EHF has traditionally involved the use of porcine pancreatic enzymes.This article is protected by copyright.

A perspective on the pediatric death from oral food challenge reported from the Allergy Vigilance Network
AbstractThe current edition of Allergy contains a report of 18 food allergy deaths from the French Anaphylaxis Vigilance Network (AVN) from 2002‐20181. The AVN maintains a database of food allergy related severe anaphylaxis formed of voluntary, structured reports of anonymous patients submitted by allergists. Therefore, no population estimates can be made, but important cases can be revealed.This article is protected by copyright. All rights reserved.

Innate Immunity in Allergy
AbstractInnate immune system quickly responds to invasion of microbes and foreign substances through the extracellular and intracellular sensing receptors, which recognize distinctive molecular and structural patterns. The recognition of innate immune receptors leads to the induction of inflammatory and adaptive immune responses by activating downstream signaling pathways. Allergy is an immune‐related disease and results from a hypersensitive immune response to harmless substances in the...

AbstractS. aureus is being recognized as a major co‐factor in atopic diseases such as atopic dermatitis, chronic rhinosinusitis with nasal polyps, and asthma. The understanding of the relationship between S. aureus virulence factors and the immune system is continuously improving. Although the precise mechanism of the host's immune response adaptation to the variable secretion profile of S. aureus strains continues to be a matter of debate, an increasing number of studies have reported on...

AbstractAsthma is a chronic inflammatory disease characterized by recurrent airways obstruction, airway hyperresponsiveness (AHR), airway inflammation and airway remodeling, which is often associated with allergy and allergic rhinitis. Many patients with asthma are poorly controlled by current drug treatment, particularly a subgroup of patients with difficult‐to‐treat severe asthma, characterized by chronic symptoms, severe exacerbations, progressive loss of lung function and resistance to...

Precision Medicine for the discovery of treatable mechanisms in severe Asthma
SummaryAlthough the complex disease of asthma has been defined as being heterogeneous, the extent of its endophenotypes remain unclear. The pharmacological approach to initiating treatment has, until recently, been based on disease control and severity. The introduction of antibody therapies targeting the Type2 inflammation pathway for patients with severe asthma has resulted in the recognition of an allergic and an eosinophilic phenotype, which are not mutually exclusive. Concomitantly,...

Prick-puncture test is the primary diagnostic modality for Immunoglobulin E (IgE) mediated hypersensitivity reactions1. Allergen extracts are applied to the skin with a prick-puncture device. Wheal and flare diameters are measured fifteen minutes after application and compared with positive (histamine) and negative (saline) controls2. Although this technique is very sensitive for the diagnosis of IgE mediated hypersensitivities, it is occasionally deferred because of concerns for discomfort, particularly...

Prediction of acute asthma exacerbation severity and interrater reliability of manual pulsus paradoxus measurement
Pulsus paradoxus (PP) represents an exaggeration of the normal fluctuation of left ventricular stroke volume and systolic blood pressure during the respiratory cycle.1 This physiologic phenomenon was first described by Lower in 1669 and the term pulsus paradoxus first applied by Kussmaul in 1873.2 PP measurement is recommended to identify or assess the severity of acute asthma exacerbations, tension pneumothorax, cardiac tamponade and other potentially life-threatening disorders.3

Food Allergy, Eosinophilic Esophagitis and the Enigma of IgG4
The recognition that IgE, formerly known as reagin, is central to the pathogenesis of allergic disease dates back nearly a century to the seminal work of Prausnitz and Kustner. By contrast, IgG4 represents an antibody subclass that is often increased in the setting of allergic disease but whose role in disease pathogenesis is less clear1. Reports in the 1980s suggested that allergen-specific IgG4 could play a role as an anaphylactic antibody, but subsequent research cast significant doubt on this...

Do eosinophils contribute to oxidative stress in mild asthma?
AbstractAsthma is an obstructive airway disease that involves chronic inflammation of the bronchial mucosa. In asthmatics, reactive oxygen species (ROS) production is elevated and cannot be countered effectively by antioxidant mechanisms, leading to increased oxidative stress levels compared to healthy subjects.1 ROS likely originate from inflammatory cells (eosinophils, neutrophils and macrophages) and mitochondria and their deleterious activity can result in lipid peroxidation products,...

Fungal extracts stimulate solitary chemosensory cell expansion in noninvasive fungal rhinosinusitis
BackgroundSolitary chemosensory cells (SCCs) are rare epithelial cells enriched in nasal polyps and are the primary source of interleukin‐25 (IL‐25), an innate cytokine eliciting T‐helper 2 (Th2) immune response. Although it is proposed that SCCs are stimulated by antigens released by upper airway pathogens, the exogenous triggers of human SCCs remain elusive. We studied patients with noninvasive fungal rhinosinusitis to determine whether extracts of Aspergillus fumigatus and Alternaria alternata...
