Background: The relationship between allergy and celiac disease (CD) is not clear.
Objective: The objective of this article is to investigate the association of CD and CD antibody positivity with hay fever, asthma and immunoglobulin (Ig)E sensitization in a general adult population.
Methods: A total of 2297 individuals were screened for CD antibodies and underwent allergy testing. CD antibody-positive participants were invited to undergo clinical evaluation including biopsies. Additionally, biobank blood samples from four population-based studies (6423, 973, 1718 and 1101 participants) with data on IgE sensitization to inhalant allergens were screened for CD antibodies. CD antibody-positive participants were screened for serum IgE against food allergens in three biobank studies. CD-antibody positivity was defined as IgA or IgG tissue transglutaminase ≥7 U/ml and/or IgG deamidated gliadin peptide ≥10 U/ml.
Results: The nine participants (0.4%) diagnosed with CD had significantly higher prevalence of IgE sensitization to wheat and dust mites. The prevalence of CD antibody positivity was 0.8% (18/2297), and these participants had a significantly higher prevalence of IgE sensitization to food allergens (Fx5), egg, dust mites and mugwort. In the biobank studies, the prevalence of CD antibody positivity was 0.8% to 1.2%. One study showed a positive association between CD antibody positivity and IgE sensitization for dog, horse and food allergens.
Conclusion: We found a possible association of CD and IgE sensitization to some food and inhalant allergens in the Health2006 study. In further studies, however, we could not consistently replicate these associations.

The European Commission authorized the use of dried yellow mealworm (Tenebrio molitor - TM) as a food ingredient under Regulation EU 2021/882. As TM emerges as an important allergen source, sensitization and allergy to TM in various populations need investigation. The aim of this study was to assess the incidence of sensitization to TM before its introduction as a food ingredient in Poland, as well as checking the occurrence of co-sensitivity to TM and other invertebrate allergenic extracts and molecules.

Numerous studies have reported on the types of aeroallergen sensitization in various pediatric allergic diseases, but limited data compared the types of aeroallergen sensitization across different pediatric allergic diseases. The aim of this study is to explore the nature and significance of aeroallergen sensitization in diverse pediatric allergic conditions. A comparative analysis was carried out on aeroallergen sensitization in children suffering from allergic diseases who visited the Otolaryngology, Respiratory, and Dermatology Departments between January 2019 and December 2023.

Insights into the underlying immunological mechanisms of prophylactic sublingual immunotherapy (SLIT) may support the development of new strategies for improved prevention and treatment of food allergy. Here, we investigated the humoral, regulatory and sublingual tissue immune response to prophylactic SLIT administration of a single purified peanut allergen in Brown Norway (BN) rats. BN rats received daily sublingual administration of peanut allergen Ara h 6 for three weeks.

Aims: We investigated sensitization to food allergens as a prognostic factor for wheezing in children with recurrent wheezing and compared serum club cell 16 (CC16) and surfactant protein D (SP-D) among these children with and without sensitization to food allergens.
Materials And Methods: Children with recurrent wheezing were enrolled in this prospective cohort study. Specific IgE to five common food allergens (Fx5) was assessed at baseline, and children were followed-up for 1 year for new-onset wheezing episodes.

Background: Allergic Rhinitis (AR) is an inflammatory condition characterized by nasal mucosa remodeling, driven by Immunoglobulin E (IgE). Platycodin D (PLD) exhibits a wide range of bioactive properties.
Aim: The aim of this work was to investigate the potential protective effects of PLD on AR, as well as the underlying mechanisms.
