Tibor Z Veres
The airway mucosa is the primary tissue site exposed to inhaled particulate matter, which includes pathogens and allergens. While most inhaled particles are eliminated from the airways via mucociliary clearance, some pathogens may penetrate the mucosal epithelial barrier and an effective activation of the mucosal immune system is required to prevent further pathogen spread. Similarly, inhaled environmental allergens may induce an aberrant activation of immune cells in the airway mucosa, causing allergic airway disease...

Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICS) represent the standard of care for the majority of patients. Combination ICS/long-acting beta2 -agonist inhalers are preferred for most adults who fail to achieve control with ICS therapy...

Rates of allergy-test positivity vary by country and by regions within countries. Several studies have looked at allergy test results to determine the most common allergens. Many of these studies have been based on surveys or on studies of small numbers of tests. Positivity rates for allergy tests are poorly defined in the northern midwestern region of the United States. We conducted a study to identify the rates of positive allergy tests for both inhalant/respiratory allergens and food allergens in the upper Midwest...

Eosinophil degranulation is a determining factor in allergy-mediated airway pathology. Receptor-mediated degranulation in eosinophils requires vesicle-associated membrane protein 7 (VAMP-7), a principal component of the SNARE fusion machinery. The specific contribution of eosinophil degranulation to allergen-induced airway responses remains poorly understood. We generated mice with VAMP-7 gene deficiency exclusively in eosinophils ( eoCRE/V7 ) from a cross using eosinophil-specific Cre recombinase-expressing mice crossed with VAMP-7 f/f mice...

BACKGROUND: Component resolved diagnosis (CRD) allows to precisely identify the sensitization to specific molecules of a given allergenic source, resulting in an important improvement in clinical management, particularly of polysensitized subjects. This will end in the correct prescription of allergen immunotherapy (AIT) for respiratory allergy and in adequate avoidance diets or prescription of self-injectable adrenaline in food allergy. OBJECTIVE: The aim of this multicenter, real life study is to evaluate the percentage change of the diagnostic-therapeutic choice in polysensitized patients with respiratory allergy and in patients with food allergy, after using CRD compared to a first level diagnosis, along with an economic analysis of the patient's overall management according to the two different approaches...

An estimated 10% to 30% of the global population has an allergic disease. Clinical presentations of allergic diseases, respiratory infections, and autoimmune conditions have similar features. Allergy and immunologic testing can help clarify the diagnosis and guide treatment. Immediate immunoglobulin E (IgE) and delayed T cell-mediated reactions are the main types of allergic responses. The allergens suspected in an immediate IgE-mediated response are identified through serum IgE-specific antibody or skin testing...

Secondary food allergies due to cross-reactivity between inhalant- and food allergens are a significant and increasing global health issue. Cross-reactive food allergies predominantly involve plant-derived foods resulting from a prior sensitization to cross-reactive components present in pollen (grass, tree, weeds) and natural rubber latex (NRL). But also primary sensitisation to allergens present in fungi, insects and both non-mammalian and mammalian meat might induce cross-reactive food allergic syndromes...

Asthma is a heterogeneous condition involving various levels of chronic airway inflammation, bronchoconstriction, airway hyperresponsiveness, and mucus production. Although inhaled corticosteroids and long-acting bronchodilators have improved patient outcomes, asthma remains uncontrolled for at least 10% of patients, even when use of these therapies is maximized. Improved understanding of the biology, genetics, and role of immune cell signaling in asthma has led to the development of immunobiologic therapies...

Background: Oral allergy syndrome (OAS) is a type of allergic reaction that mainly occurs on oral contact with raw fruit, vegetables, or nuts. The most common type of OAS is birch pollen-related food allergy. Although OAS is a common food allergy in adults, only few epidemiologic studies have been reported in Korea. Here we investigate the prevalence and triggers of birch pollen-related food allergy. Methods: We conducted a retrospective chart review of 1,427 patients who underwent a skin prick test for inhalant allergens at the Asthma and Allergy Clinic in Seoul National University Bundang Hospital from January 2011 to December 2016...

Wheat allergy specifically refers to the adverse reaction involving IgE antibody to one or more protein fraction of wheat such as albumin, globulin, gliadin and glutenin (gluten). The majority of IgE-mediated reactions to wheat involve albumin and globulin fraction while gluten (gliadin & glutenin) also cause allergy (Celiac disease). Allergic reactions to wheat may be caused by ingestion of wheat containing foods or inhalation of flour (Bakers asthma). The present study was an effort to explore the antibody response of different proteins present in wheat...

Although skin-prick testing (SPT) is commonly used by allergists in the evaluation of allergy, in-vitro testing for specific IgE (sIgE) is an attractive alternate because it can be performed remotely and is of utility when SPT is contraindicated, as in patients on anti-histamines, or with dermatitis or severe eczema. It is, however, necessary to determine the extent of correlation between the in-vitro and in-vivo methods. In this study, we examined the qualitative concordance between SPT and sIgE as measured on the HYTEC™288 platform for 10 commonly encountered inhalant allergens in 232 subjects, and analysed the performance characteristics for the HYTEC™288...
