Background. Cross-reactivity among phylogenetically distant invertebrates—such as mites, crustaceans, and mollusks—is mainly driven by conserved panallergens including tropomyosin, arginine kinase, and troponin C. However, the clinical impact and molecular basis of these cross-reactivities remain incompletely defined. Methods. A multicenter observational study was conducted in 3,777 patients reactive to at least one arthropod or invertebrate allergen […]

Background. The allergic asthma phenotype is the most extensively investigated. However, few studies have explored the association between sensitization to different aeroallergens, asthma severity and blood eosinophil counts, an important biomarker of Type 2 inflammation. This study aims to evaluate associations between sensitization to aeroallergens, severity of asthma, eosinophilic phenotypes and age of onset of […]

Background. Tree nut and peanut allergy are common, and often persistent conditions, that significantly affect quality of life. Multiple nut avoidance is common due to cross-reactivity concerns but may cause unnecessary restrictions. Data regarding multiple nut oral food challenges (MN-OFC) remains limited. Our aim was to evaluate the safety and clinical impact of MN-OFC in […]

Background. Flaxseed allergy is a rare and potentially underdiagnosed condition. In recent years, sensitization to flaxseed has increased due to its growing presence in the human diet. This study presents three distinct cases of flaxseed allergy and discusses the strengths and limitations of current diagnostic tools in identifying this emerging allergy. Methods. Each case underwent […]

Background. Anaphylaxis is the most severe form of acute systemic allergic reactions. Several recommendations have been proposed to guide and standardize anaphylaxis approach and management. The objective of this study is to characterize a cohort of patients referred through an anaphylaxis fast-track system, to enhance and standardize anaphylaxis patient care. Methods. Observational study including patients […]

Background. Hereditary angioedema (HAE) is a rare genetic disorder with variable prevalence, characterized by recurrent swelling in various parts of the body, including potential laryngeal attacks, significantly affecting patients’ quality of life. Methods. A nationwide, cross-sectional survey study was conducted between December 2023 and June 2024, targeting adults (aged 18 and older). The patients filled […]
Background. The diagnosis of immediate drug allergy (DA) relies on a combination of skin tests (ST), drug provocation tests (DPT), specific IgE levels (sIgE) and/or basophil activation tests (BAT). We aimed to compare BAT results with those of other allergy tests in patients with suspected immediate DA to a heterogeneous group of drugs, aiming to […]

Background. Oral immunotherapy (OIT) is a promising strategy for severe and persistent cow’s milk (CM) allergy. However, clinical experience concerning long-term follow-up is scarce. The objective is to assess long-term efficacy and safety of maintenance phase of OIT in real-life. Methods. Prospective study of children with severe IgE-mediated CM allergy that underwent CM-OIT, and were […]

Background. Soy allergy represents a diagnostic challenge, particularly when mediated by Gly m 4, a PR-10 protein known for its cross-reactivity with birch pollen allergens. Traditional diagnostic methods, including skin prick tests (SPTs) and specific IgE assays, often lack sensitivity or specificity, especially for Gly m 4-mediated allergies. Methods. In this study, the basophil activation […]

Background. Small airway dysfunction (SAD) is increasingly recognized as a key feature in asthma, influencing control, exacerbations, and severity. Spirometry remains the gold standard for lung function assessment but mainly reflects large airways, whereas impulse oscillometry (IOS) offers complementary insights into peripheral airway function. Methods. A retrospective analysis was conducted on 218 patients referred for […]
