Storage mite concentrations are underestimated compared to house dust mite concentrations.

Dwellings are increasingly well insulated to save energy and this leads to higher humidity and temperature, which improves conditions for mites. Dermatophagoides antigens are the main allergens involved and tested in atopic asthma. We developed three new species-specific quantitative PCR (qPCR) methods for house dust mites (Dermatophagoides pteronyssinus and D.

Fungal contamination of wind instruments: Immunological and clinical consequences for musicians.

Introduction: Playing a wind instrument is an increasingly reported cause of hypersensitivity pneumonitis. However, current knowledge about contamination of wind instruments by fungi and specific fungal sensitization is scarce. Therefore, we aimed: (i) to assess the current prevalence and type of fungal contamination of wind instruments, (ii) to identify potential risk factors associated with instrument contamination, and (iii) to evaluate the prevalence of sensitization to these fungi among musicians.

An immunoproteomic approach revealed antigenic proteins enhancing serodiagnosis performance of bird fancier's lung.

Background: Bird fancier's lung (BFL) caused by repeated inhalation of avian proteins is the most common form of hypersensitivity pneumonitis. However, the exact identification of proteins involved is unknown, and serological test use for diagnosis need to be standardized. The objectives of this study were (i) to identify antigenic proteins from pigeon droppings (ii) to provide information about their location in avian matrices and (iii) to produce them in recombinant proteins to evaluate their diagnostic performances.

Assessment of pets (cats and dogs) in homes using electrostatic dust collectors and QPCR: new tools to evaluate exposure and risk of allergies.

Contradictory results are found in the literature concerning fungi, bacteria, and pet exposure and the risk of developing asthma. All these allergens have been thoroughly studied separately in cohort studies, and a variety of sampling and analytical methods are used. It is already possible to characterize fungi, mites, and bacteria by QPCR.

New Commercially Available IgG Kits and Time-Resolved Fluorometric IgE Assay for Diagnosis of Allergic Bronchopulmonary Aspergillosis in Patients with Cystic Fibrosis.

Allergic bronchopulmonary aspergillosis (ABPA) is difficult to diagnose; diagnosis relies on clinical, radiological, pathological, and serological criteria. Our aim was to assess the performance of two new commercially available kits and a new in-house assay: an Aspergillus fumigatus enzyme-linked immunosorbent assay (ELISA) IgG kit (Bordier Affinity Products), an Aspergillus Western blotting IgG kit (LDBio Diagnostics), and a new in-house time-resolved fluorometric IgE assay (dissociation-enhanced lanthanide fluorescent immunoassay, or DELFIA) using recombinant proteins from an Aspergillus sp. recently developed by our laboratory for ABPA diagnosis in a retrospective study that included 26 cystic fibrosis patients.

Western blotting as a tool for the serodiagnosis of farmer's lung disease: validation with Lichtheimia corymbifera protein extracts.

Electrosyneresis and double diffusion are immunoprecipitation techniques commonly used in the serological diagnosis of Farmer's lung disease (FLD). These techniques are reliable but lack standardization. The aim of this study was to evaluate Western blotting for the serodiagnosis of FLD.

Immunoreactive proteins of Saccharopolyspora rectivirgula for farmer's lung serodiagnosis.

Purpose: Saccharopolyspora rectivirgula is the principal cause of farmer's lung disease (FLD). Serodiagnosis is based on immunoprecipitation techniques or enzyme immunoassays with homemade crude antigens and is not standardized. We aimed to produce specific recombinant antigens for the development of a standardized ELISA.

Immunoproteomics for serological diagnosis of hypersensitivity pneumonitis caused by environmental microorganisms.

Diagnosis of immunoallergenic pathologies due to microorganisms such as hypersensitivity pneumonitis includes detection of circulating specific antibodies. Detection of precipitins has classically been performed using immunoprecipitation techniques with crude antigenic extracts from microorganisms implicated as etiologic agents. However, these techniques lack standardization because of the different composition of fungal antigenic extracts from one batch to another.

Immunogenic proteins specific to different bird species in bird fancier's lung.

Bird fancier's lung (BFL) is a disease produced by exposure to avian proteins present in droppings, blooms, and serum of a variety of birds. Although serological test results are currently used to confirm clinical diagnosis of the disease, bird species specificity is poorly understood. This study aimed to contribute to a better understanding of the specificity of immunogenic proteins revealed from the droppings of three bird species.

Immuno-reactive proteins from Mycobacterium immunogenum useful for serodiagnosis of metalworking fluid hypersensitivity pneumonitis.

Metalworking fluid-associated hypersensitivity pneumonitis (MWF-HP) is a pulmonary disease caused by inhaling microorganisms present in the metalworking fluids used in the industrial sector. Mycobacterium immunogenum is the main etiological agent. Among the clinical, radiological and biological tools used for diagnosis, serological tests are important.

New evidence of the involvement of Lichtheimia corymbifera in farmer's lung disease.

Farmer's lung disease (FLD) is a form of hypersensitivity pneumonitis resulting from recurrent exposure to moldy plant materials. We investigated and compared the initial response of respiratory epithelium after exposure to extracts of Sacharopolyspora rectivirgula, Lichtheimia corymbifera (formerly Absidia corymbifera), Eurotium amstelodami and Wallemia sebi. The two criteria for selection of these species were their high prevalence in the hay handled by FLD patients and the presence of high levels of specific precipitins to these molds in FLD patients’ sera.
