Background: Component-Resolved diagnosis (CRD) can help to establish immunoglobulin E (IgE) sensitization profiles and potential risks and determines whether specific IgE is the result of primary sensitization or cross-reactivity, especially for those who are polysensitized.

Background: Component-resolved diagnosis (CRD) allows to identify single molecular allergen components, and constitutes a routine practice in many allergy units. However, skin prick test (SPT) remains the technique of choice in many otorhinolaryngology departments, thus increasing the risk of using inadequate immunotherapies in patients with respiratory allergies. This study aimed to compare sensitization profles determined by SPT and CRD in patients with respiratory allergy, and to explore the relationship between sensitization and type and severity of the respiratory disease.

Introduction: Chronic pain is related to gastrointestinal (GI) functions because food components affect inflammation and pain through their action on the GI immune and/or neural system and because many analgesics interact with the gut to alter its structure and function. Immunoglobulin G4 (IgG4) are food-specific antibodies resulting from exposure of the gut immune system to nutrients. High IgG4 levels have been found to be associated with inflammation.

Objective: Using multiplex microarray-based component resolved diagnosis (CRD) to investigate the allergen sensitization profile of allergic asthma patients in southern China.

Background: Molecular antibody reactivity profiles have not yet been studied in depth in patients treated by sublingual house dust mite (HDM) tablet immunotherapy. Humoral immune responses to a large panel of HDM mite allergens were studied using allergen microarray technology in a subset of clinically defined high and low responder patients from a double-blind placebo-controlled allergen-specific immunotherapy (AIT) trial using sublingual 300 IR HDM tablets.

Introduction: Asymptomatic sensitization is defined as the presence of positive skin prick test (SPT) and/or positive serum allergen-specific IgE in the absence of clinical allergic symptoms. Currently, there is no convincing explanation why some people with positive allergen tests do not show symptoms. We aimed to investigate the house dust mite (HDM)-specific IgE and IgG4 repertoire in asymptomatic HDM-sensitized subjects and HDM-induced allergic rhinitis(AR) patients.

Background: A genetic defect in the epidermal barrier protein filaggrin (FLG) plays a major role in the etiology of eczema and associatedallergic airways diseases.However, it is still controversial to what extend loss-of-function (LOF)mutations in FLG contribute to the development and persistence of food allergies.

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.

Abstract:Background: Flow cytometry is a well-accepted approach for immune profiling; however, its value is restricted by the limited number of markers that can be analyzed simultaneously. Mass cytometry/CyTOF offers broad-scale immune characterization integrating large number of parameters. While partial blood phenotyping was reported in atopic dermatitis (AD), patients’ comprehensive profiling, critical for leveraging new targeted treatments, is not available. IL-21 may be involved in inflammatory skin diseases but its role in AD is not well established.

Background: Pollen food allergy syndrome (PFAS) is a frequently underdiagnosed disease due to diverse triggers, clinical presentations, and test results. This is especially relevant in geographic areas with a broad spectrum of pollen sensitization, such as Southern Europe.

Background: IL-13 is an archetypal T2 cytokine central to the clinical disease expression of asthma. The IL-13 response genes, which are upregulated in central airway bronchial epithelial of asthma patients, can be normalized by high-dose inhaled steroid therapy in severe asthma. However, this is not the case within the peripheral airways. We have sought to further understand IL-13 in the peripheral airways in severe asthma through bronchoalveolar analysis.

Background: Diagnostic tests for fish allergy are hampered by the large number of under-investigated fish species. Four salmon allergens are well-characterized and registered with the WHO/IUIS while no catfish allergens have been described so far. In 2008, freshwater-cultured catfish production surpassed that of salmon, the globally most-cultured marine species. We aimed to identify, quantify, and compare all IgE-binding proteins in salmon and catfish.

Abstract:Anaphylaxis is defined as a severe, life-threatening, rapidly evolving, generalized or systemic hypersensitivity reaction.Typical clinical signs include bronchoconstriction, vasodilatation, and hypovolemia, which can lead to respiratory insufficiency, shock, and death.3 The term allergic anaphylaxis is used when the reaction is mediated by an immunologic mechanism (IgE, IgG, and immune complex [IC] complement-related). Based on the involvement of IgE is the reaction then subclassified into IgE-mediated and not IgE-mediated reaction.

Background: The association between grass pollen exposure and early markers of asthma exacerbations such as lung function changes and increase in airway inflammation is limited. We investigated the associations between short-term grass pollen exposure and lung function and airway inflammation in a community-based sample, and whether any such associations were modified by current asthma, current hay fever, pollen sensitization, age, and other environmental factors.

Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a type 2-mediated inflammatory disease associated with significant clinical, social, and economic burdens and high unmet therapeutic need. Dupilumab, a fully human monoclonal antibody targeting the interleukin-4 receptor α (IL-4Rα) subunit, demonstrated efficacy and acceptable safety in CRSwNP and other type 2 diseases (eg, atopic dermatitis and asthma). We now report the local effects of dupilumab on type 2 inflammatory biomarkers in nasal secretions and nasal polyp tissues of patients with CRSwNP in a randomized, placebo-controlled, phase 2 trial

Background: Patients with peach allergy due to nsLTP sensitisation constitute a heterogeneous group in terms of sensitisation profile and severity. This could be due to the presence of additional allergies to pollens. The aim of this study was to analyse the clinical characteristics, sensitization profile, and severity of reactions in peach-allergic patients sensitised to nsLTP from two Mediterranean areas with different pollen exposure.

Background: Atopic dermatitis (AD) is associated with a dysregulation of the skin barrier and may predispose to the development of secondary allergic conditions, such as asthma. Tmem79ma/ma mice harbor a mutation in the gene encoding Transmembrane Protein 79 (or Mattrin), which has previously been associated with AD. As a result of the Tmem79 gene mutation, these mice have a defective skin barrier and develop spontaneous skin inflammation. In this study, Tmem79ma/ma mice were assessed for the underlying immunological response in the development of spontaneous skin and lung inflammation

Background: Oral immunotherapy (OIT) for food allergy improves the quality of life (QOL) of children from parental perspective but little is known about the child perception.

Background: Peanut allergy (PA) is a common, potentially life-threatening and typically lifelong condition with a significant burden of illness. However, information is lacking on how persons with PA (PwPA) and their caregivers perceive the psychosocial impact of living with PA. The Allergy to Peanuts imPacting Emotions And Life 1(APPEAL-1) survey, conducted across Europe, investigated the experience and impact of living with PA. Here, we report data evaluating the psychosocial impact of PA on PwPA and their caregivers.

Background: Obesity associated with various complications has increased worldwide. Body weight gain alters lipid metabolites (especially sphingolipids) contributing to obesity-induced inflammation. However, the significance of the metabolites in the development of obese asthma is not yet clear.
