Allergen extracts are prepared from a wide variety of source materials including pollens, fungi, arthropods, animal danders, foods, and dusts. The composition of allergen extracts can vary depending on the allergen source, manufacturing process, and storage conditions. Allergen-specific immunoglobulin E (IgE) assays and skin tests employ a variety of allergen-containing reagents that confer spe...

Allergen-specific immunotherapy (AIT) is an allergen-specific treatment for people with IgE-related allergies. used to treat allergic disorders when symptoms persist despite medication and allergen avoidance. The therapy presumed effective if it reduces the use of medications, improves quality life even after discontinuation treatment, as well prevents conversion one type allergy other developm...

More than 40% of allergic patients suffer from grass pollen allergy. Phl p 1, the major timothy grass pollen allergen, belongs to the cross-reactive group 1 grass pollen allergens that are thought to initiate allergic sensitization to grass pollen. Repeated allergen encounter boosts allergen-specific IgE production and enhances clinical sensitivity in patients. To investigate immunological mech...

Allergen-specific immunotherapy (SIT) is the only allergen-specific treatment for allergy. It can prevent progression of the disease and has a long-lasting therapeutic effect. Since SIT is allergen-specific, the identification of the disease-eliciting allergen is an essential prerequisite for the accurate prescription of treatment. Diagnostic tests based on allergen extracts consist of mixtures...

Peanut and tree-nut allergies have increased dramatically in prevalence, especially children. Historically, children with food been treated through strict avoidance of the allergen. Recently, an oral preparation peanut allergen (Palforzia) was approved for immunotherapy (ie, desensitization) 4 to 17 years old. This article reviews its role allergies.

BACKGROUND Questionnaires are commonly used in epidemiologic studies to obtain information about house characteristics in order to predict the household aeroallergen exposure levels. However, the reliability of the predictions made with the questionnaires has not been evaluated. To address this issue, we compared objectively measured fungal propagules including the most frequently isolated mold...

Abstract The immunomodulatory properties of probiotics are particularly important at the establishment Th 1-Th 2immune balance early in life. A skewing to response driven by dendritic cell regulation can lead airway alteration during respiratory allergy and virus infection. Previous work from our lab have determined that oral supplementation mice with Lactobacillus johnsonii (Lj) resulted be pr...

Exposure to fungi, particularly in water damaged indoor environments, has been thought to exacerbate a number of adverse health effects, ranging from subjective symptoms such as fatigue, cognitive difficulties or memory loss to more definable diseases such as allergy, asthma and hypersensitivity pneumonitis. Understanding the role of fungal exposure in these environments has been limited by met...

Preparation of high quality allergen extracts is essential for the diagnosis and immunotherapy of allergic disorders. Standardization of allergen extracts concerns determination of the allergen unit, development of reference material and measurement of the overall IgE binding capacity of an allergen extract. Recently, quantification of individual allergens has been the main focus of allergen st...
