    Abstract The first reports of hypersensitivity reactions following the rollout of COVID-19 vaccination programs have raised public concern. Given the recent availability and novel mechanisms of COVID-19 vaccines, there is limited data on possible hypersensitivity reactions. Although it seems rare, the incidence of anaphylaxis for approved COVID-19 vaccines has been suggested as being higher when compared to previous vaccines. Adequate risk assessment, recognition, classification, and management of hypersensitivity reactions is crucial to ensure safe immunization and avoid misinformation and vaccine hesitancy. In this review, we present an overview of the types of hypersensitivity reactions that can potentially occur due to vaccination and the possible allergenic components of COVID-19 vaccines, as well as a suggestion for causality and risk assessment for the BNT162b2, mRNA-1273 and AZD1222 vaccines.

    Abstract Beer is one of the most consumed alcoholic beverages worldwide but allergic reactions to this beverage are uncommon. The authors present a case report of a 32-year-old male patient, sent to our Allergy and Immunology Department due to anaphylaxis minutes after Franziskaner beer ingestion. He tolerates all other alcoholic beverages. Prick tests to cereals were positive to wheat, corn and barley, as well as to peach. Prick-to-prick tests were performed with nine beer brands, all positive. Immunoglobulin (Ig)E to Pru p 3 was 14.8 kU/L. Sodium dodecyl sulfate polyacrylamide gel electrophoresis inhibition immunoblotting was performed with the Franziskaner beer extract in solid phase and both cereal extracts (wheat, barley and corn) and Pru p 3 as inhibitors. Extracts from wheat, barley and corn, and Pru p 3 purified protein were able to inhibit almost totally the IgE-binding to the Franziskaner beer extract. It seemed likely that the IgE-binding bands detected in the Franziskaner beer extract could be an LTP from cereals.

    Abstract Abstract Skin prick testing is an essential test procedure to confirm sensitization in IgE-mediated allergic disease in subjects with rhinoconjunctivitis, asthma, urticaria, anapylaxis, atopic eczema and food and drug allergy. This manuscript reviews the available evidence including Medline and Embase searches, abstracts of international allergy meetings and position papers from the world allergy literature. The recommended method of prick testing includes the appropriate use of specific allergen extracts, positive and negative controls, interpretation of the tests after 15 – 20 minutes of application, with a positive result defined as a wheal ≥3 mm diameter. A standard prick test panel for Europe for inhalants is proposed and includes hazel ( Corylus avellana ), alder ( Alnus incana ), birch ( Betula alba ), plane ( Platanus vulgaris ), cypress ( Cupressus sempervirens ), grass mix ( Poa pratensis , Dactilis glomerata , Lolium perenne , Phleum pratense , Festuca pratensis , Helictotrichon pretense ), Olive ( Olea europaea ), mugwort ( Artemisia vulgaris ), ragweed ( Ambrosia artemisiifolia ), Alternaria alternata ( tenuis ), Cladosporium herbarum , Aspergillus fumigatus , Parietaria , cat, dog, Dermatophagoides pteronyssinus , Dermatophagoides farinae , and cockroach ( Blatella germanica ). Standardization of the skin test procedures and standard panels for different geographic locations are encouraged worldwide to permit better comparisons for diagnostic, clinical and research purposes.

    Abstract Background: Fruits and vegetables are rich in compounds with proposed antioxidant, anti-allergic and anti-inflammatory properties, which could contribute to reduce the prevalence of asthma and allergic diseases.
    Objective: We investigated the association between asthma, and chronic rhino-sinusitis (CRS) with intake of fruits and vegetables in European adults.
    Methods: A stratified random sample was drawn from the Global Allergy and Asthma Network of Excellence (GA
    Results: A total of 3206 individuals had valid data on asthma and dietary exposures of interest. 22.8% reported having at least 1 asthma symptom (asthma score ≥1), whilst 19.5% had CRS. After adjustment for potential confounders, asthma score was negatively associated with intake of dried fruits (β-coefficient -2.34; 95% confidence interval [CI] -4.09, -0.59), whilst CRS was statistically negatively associated with total intake of fruits (OR 0.73; 95% CI 0.55, 0.97). Conversely, a positive association was observed between asthma score and
    Conclusion and clinical relevance: There was no consistent evidence for an association of asthma or CRS with fruit and vegetable intake in this representative sample of European adults.
