Exposure to cow's milk constitutes one of the most common causes of food allergy. In addition, exposure to soy proteins has become relevant in a restricted proportion of milk allergic pediatric patients treated with soy formulae as a dairy substitute, because of the cross-allergenicity described between soy and milk proteins . We have previously identified several cross-reactive allergens between milk and soy that may explain this intolerance. The purpose of the present work was to identify epitopes in the purified αS1-casein and the recombinant soy allergen Gly m 5...

BACKGROUND: Household animal dander has been implicated as aeroallergen in childhood atopic diseases. Many parents seek healthcare advice if household pet keeping may be detrimental in atopic eczema (AE) and atopies. AIM: We investigated if skin sensitization by cat/dog dander was associated with disease severity and quality of life in children with AE. METHODS: Demographics, skin prick test (SPT) results, disease severity (Nottingham eczema severity score NESS), Children Dermatology Life Quality Index (CDLQI), blood IgE and eosinophil counts of a cohort of AE patients were reviewed...

BACKGROUND: Living with an allergic disease has consequences for both affected children and their families. The aim of this qualitative study was to gain deeper knowledge of what life is like for families of children with severe allergic disease, in order to improve care and thereby reduce the consequences of living with a chronic disease. METHODS: Four focus group interviews were performed with Swedish parents of children, aged 6-11 and 12-16 years, with severe allergic disease (from one or more allergic conditions, such as food allergy/eczema/hay fever/asthma)...

Stability to proteolytic degradation in the digestive tract is considered a general feature shared by most food allergens. Current digestibility models exclusively utilize purified allergen proteins, neglecting the relevant effects of matrix that occur for foodstuff systems. In the present study, we investigated digestion stability of the major peanut allergens directly in the natural matrix using an in vitro static model that simulates the gastrointestinal digestion including the oral, gastric, duodenal and intestinal (brush border membrane enzymes) phases...

There are a number of examples of immunologic cross-reactivity elicited by pollens, fruits, seeds, and nuts of closely related plant species. Such cross-reactivity is of particular concern for patients with food allergies. In this report, we investigated a spice (mahleb) that is prepared from the kernel of the St. Lucie cherry, Prunus mahaleb, for cross-reactivity with almond (Prunus dulcis), using enzyme-linked immunosorbent assay (ELISA) and Western blot. Almond and mahleb are members of the same genus. Cross-reactivity between the mahleb and almond was demonstrated by reaction of cherry and almond kernel protein extracts with antibodies raised against almond proteins...

Histamine is a mediator of many physiological processes. It plays an important role in modulating allergy reactions and immune system responses. H1 receptor is a therapeutic target for drugs applied in allergic diseases such as allergic rhinoconjunctivitis, urticarial, or atopic dermatitis. H1-antihistamines display different chemical structures, pharmacokinetics and a potential for drug-drug and drug-food interactions. Drug-food interactions are known to reduce therapeutic effects of the medicine, as well as to induce a potent adverse drug reactions...

PURPOSE OF REVIEW: Molecular allergology uses pure, mainly recombinant and structurally defined allergen molecules and allergen-derived epitopes to study mechanisms of IgE-associated allergy, to diagnose, and even predict the development of allergic manifestations and to treat and prevent IgE-associated allergies. Atopic dermatitis, a chronic inflammatory skin disease is almost always associated with IgE sensitization to allergens. However, also non-IgE-mediated pathomechanisms seem to be operative in atopic dermatitis and it is often difficult to identify the disease-causing allergens...

BACKGROUND: Hematochezia is a frequent symptom in early infancy. However, it occurs very rarely within the immediate neonatal period, and its occurrence before any oral intake is particularly rare. Because of the "congenital" presentation of hematochezia in our patient, we initially considered our case to be a non-classical, potentially severe type of food protein-induced allergic proctocolitis. This diagnosis needs to be confirmed by an abnormal oral challenge test once the hematochezia has disappeared...

BACKGROUND: Recently, the nature of the lipid-ligand of Pru p 3, one of the most common plant food allergens in Southern Europe, has been identified as a derivative of the alkaloid camptothecin bound to phytosphingosine. However, the origin of its immunological activity is still unknown. OBJECTIVE: We sought to evaluate the role of the Pru p 3 lipid- ligand in the immunogenic activity of Pru p 3. METHODS: In vitro cultures of different cell types (monocyte-derived dendritic cells (moDCs), PBMCs and epithelial and iNKT-hybridoma cell lines) have been used to determine the immunological capacity of the ligand, by measuring cell proliferation, maturation markers and cytokine production...

Food allergy is an increasing phenomenon in Australia, with most recent reports of food allergy occurring in 1 in 12 children. A number of studies have demonstrated that children and adolescents with food allergies experience a decreased quality of life across a number of domains. More recent evidence suggests that this population also experiences an increased occurrence of bullying compared to similar school-aged children. Some individuals have reported being bullied because of their allergies, whilst others have reported specific allergy-related-bullying, such as being touched with foods that they are allergic to or having their food being intentionally contaminated with an allergen...

BACKGROUND: Peanut oral immunotherapy (POIT) decreases the probability of accidental recurrent systemic reactions but reactions from the therapy itself are frequent. OBJECTIVE: The purpose of this economic analysis was to characterize the potential cost-effectiveness of POIT. METHODS: Cohort simulations were used to evaluate the effect of POIT for children with peanut allergy. A POIT with probiotic was used in the base-case simulation and long-term survival was modeled using age-adjusted mortality together with the risk of food allergy-associated mortality...

BACKGROUND: Food allergies are a growing health problem and the development of therapies that prevent disease onset is limited by the lack of adjuvant-free experimental animal models. We compared allergic sensitization in patients with food allergy or Wiskott-Aldrich syndrome (WAS) and defined whether spontaneous disease in Was(-/-) mice recapitulates the pathology of a conventional disease model and/or human food allergy. METHODS: Comparative ImmunoCAP ISAC microarray was performed in patients with food allergy or WAS...
