Abstract Since the discovery of immunoglobulin E (IgE) as a mediator allergic diseases in 1967, our knowledge about immunological mechanisms IgE‐mediated allergies has remarkably increased. In addition to understanding immune response and clinical symptoms, allergy diagnosis management depend strongly on precise identification elicitors reaction. past four decades, innovations bioscience technology have facilitated production well‐defined, highly pure molecules for component‐resolved (CRD), allowing personalized disease individual patients. The first edition “EAACI Molecular Allergology User's Guide” (MAUG) 2016 rapidly became key reference clinicians, scientists, interested readers with background allergology, immunology, biology, medicine. Nevertheless, field molecular allergology is moving fast, after 6 years, new EAACI Taskforce was established provide an updated document. Guide 2.0 summarizes state‐of‐the‐art information allergen molecules, their relevance, application diagnostic algorithms practice. It designed both, clinicians guiding health care professionals through overwhelming list different available testing. Further, it provides relevance allergenic gives overview basic test formats, tests measure exposure.

Going over Fungal Allergy: Alternaria alternata and Its Allergens

Journal of Fungi, Journal Year: 2023, Volume and Issue: 9(5), P. 582 - 582

Fungal allergy is the third most frequent cause of respiratory pathologies and related to a poor prognosis asthma. The genera Alternaria Cladosporium are frequently associated with allergic diseases, being one highest prevalence sensitization. alternata an outdoor fungus whose spores disseminate in warm dry air, reaching peak levels temperate summers. can also be found damp insufficiently ventilated houses, causing what known as sick building syndrome. Thus, exposure fungal allergens occur outdoors indoors. However, not only but fragments contain detectable amounts may function aeroallergenic sources. Allergenic extracts hyphae still use for diagnosis treatment diseases variable standardised, they often random mixture allergenic ingredients casual impurities. has been difficult, knowledge about new stuck. number described Fungi remains almost constant while Plantae Animalia kingdoms.

Understanding of lipid transfer protein sensitization patterns and its clinical significance in children

Allergy and Asthma Proceedings, Journal Year: 2024, Volume and Issue: 45(2), P. 120 - 127

Published: March 1, 2024

Background: Lipid transfer proteins (LTP) are the most common food allergens in Mediterranean region. Objective: The study aimed to investigate co-sensitization patterns and cluster relationships between LTP allergen molecules across a broad range of allergen-specific sensitization patterns, clinical outcomes eastern children. Methods: Among 496 children evaluated for multiple sensitizations with multiplex testing, 105 (21%) 16 different were analyzed. Clinical reactivity was examined based on clear-cut history immunoglobulin E mediated symptoms (oral allergy syndrome [OAS], systemic reactions, anaphylaxis). Results: All included sensitive LTPs, but 56% pollen LTPs. number OAS 12 59, respectively, no cofactors reported. Pru p 3 (74%) Cor 8 (66%). Significant correlations observed heatmap other than Par j 2 Tri 14. Overall, associated increased age molecule positivity. Conclusion: In region, 21% and/or found have sensitization; however, almost half reported reactivity. hierarchical pathway highlights that distinct can act as primary sensitizers. is linked increasing numbers positivity age.

Multiplex Assays in Allergy Diagnosis: Allergy Explorer 2 versus ImmunoCAP ISAC E112i

Diagnostics, Journal Year: 2024, Volume and Issue: 14(10), P. 976 - 976

Published: May 8, 2024

ImmunoCAP ISAC E112i (ISAC) and Allergy Explorer 2 (ALEX2) detect specific immunoglobulin E (IgE) reactivity. Both multiplex assays contain molecular allergens ALEX2 additionally includes allergen extracts inhibitors that block the binding of IgE to cross-reacting carbohydrate determinants (CCDs). This study aimed compare performance by determining reactivity against and/or components using qualitative, semiquantitative, quantitative analyses all comparable in sera from 216 participants recruited South Tyrol/Italy. For extract sensitization ALEX2, analysis revealed negative corresponding 18.4% at least one positive component 81.6% cases. ISAC, results were 23.5% 76.5% cases, respectively. The CCD inhibitor eliminated CCD-positive signals detected 88.5% Based on values 0.3–14.9 ISU or kUA/L, there was good agreement between although showed higher than ISAC. addition allergen-extract tests resulted detection more sensitizations with alone. In range <15 may be effective detecting sensitizations.

ALEX versus ISAC multiplex array in analyzing food allergy in atopic children

Clinical and Molecular Allergy, Journal Year: 2022, Volume and Issue: 20(1)

ALEX multiplex array is a relatively new allergy test which analyses more than 120 allergen extracts and 170 molecular components. ISAC the most used studied to date, offering 112 In ten atopic children with multiple food allergies good agreement was observed between sIgE results for nearly all shared Presence of larger number allergens in could help clinicians improve personalized dietary advice. However positive sensitizations unknown clinical relevance were found by ALEX, potentially increasing complexity.
