BACKGROUND: Food allergy significantly impairs health-related quality of life (HRQL). Currently, it is still unknown whether diagnostic interventions for food allergy improve HRQL. We aim to assess the impact of diagnostic interventions for food allergy on HRQL. METHODS: A systematic search was performed in MEDLINE, Embase, Cochrane Library and CINAHL focused on patients with a (suspected) food allergy who underwent diagnostic interventions (i.e. skin prick test, specific IgE or oral food challenges (OFC)), and in whom HRQL was assessed...

BACKGROUND AND OBJECTIVES: Reasons for intolerance to commercial amino acid-based formulas (cAAF) in infants diagnosed with cow's milk protein allergy (CMA) remain unknown. We assume that minute amounts of proteins, presenting in the glucose polymers derived from corn starch (cGPs), can elicit the intolerance to the cAAFs observed in some infants with CMA. By replacing cGPs with glucose polymers derived from rice starch (rGPs), a new amino acid-based (nAAF) formula has been shown to be better tolerated than an existing cAAF...

Gluten from wheat, rye, and barley can trigger IgE-mediated allergy or Celiac disease in sensitive individuals. Gluten-free labeled foods are available as a safe alternative. Immunoassays such as the enzyme-linked immunosorbent assay (ELISA) are commonly used to quantify gluten in foods. However, various non-assay related factors can affect gluten quantitation. The effect of gluten-containing grain cultivars, thermal processing, and enzymatic hydrolysis on gluten quantitation by various ELISA kits was evaluated...

UNLABELLED: Consumers, especially those with allergies and/or intolerances, should have confidence in two critical areas of food safety: foods should be correctly labelled and free from contamination. To this end, global proteomic analysis employing LC-MS/MS of gluten-enriched extracts derived from 12 barley cultivars was undertaken, providing a foundation for the development of MS-based quantitative methodologies that would enable the detection of barley contamination in foods. Subsequently, a number of candidate barley-specific peptide markers were evaluated by multiple-reaction monitoring MS...

BACKGROUND: Prevalence and severity of cow's milk protein allergy (CMA) in infants are increasing. A proportion of infants with CMA still elicit signs and symptoms of CMA while ingesting commercial amino acid-based formulas (AAFs). We propose that protein in glucose polymers (GPs) derived from corn starch in the AAFs might be the cause of intolerance to AAF in some infants. We thus have produced small molecules of GPs from rice starch, eliminating the protein fraction from them, and subsequently used them as the sole source of carbohydrate in a new amino acid-based formula (NAAF)...

BACKGROUND: DC-SIGN (dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin) is a C-type lectin receptor expressed on macrophages and dendritic cells. DC-SIGN has high affinity for fucosylated glycans in several plant glycoproteins and pathogens. DC-SIGN is thought to be crucial for the development of allergic sensitization. However, the precise role of DC-SIGN in food allergy pathogenesis is not yet understood. OBJECTIVE: We sought to characterize DC-SIGN-binding glycoproteins in a panel of allergenic and non-allergenic foods...

Peanuts are among the most common food allergies, which may result in life-threatening reactions in certain people. For this reason, it is very important to monitor the presence of peanuts in the food system. Biosensors are an emerging way of detecting allergen proteins. In this research, we present a surface enhanced Raman spectroscopy (SERS) technique to detect the main allergen protein, Ara h1. The sensors were biodegradable and made out of a corn protein, zein. Nanophotonic structures on zein films consisted of gold coated pyramid structures...

BACKGROUND: Childhood allergic diseases have a major impact on a child's quality of life, as well as that of their parents. We studied the coexistence of reported allergies in children who use asthma medication. Additionally, we tested the hypothesis that asthma severity is greater among children with certain combinations of co-morbid allergic conditions. METHODS: For this cross-sectional study, 703 children (ages 4 to 12 years) from the PACMAN cohort study were selected...

Extra virgin olive oil (EVOO) with its nutraceutical characteristics substantially contributes as a major nutrient to the health benefit of the Mediterranean diet. Unfortunately, the adulteration of EVOO with less expensive oils (e.g., peanut and corn oils), has become one of the biggest source of agricultural fraud in the European Union, with important health implications for consumers, mainly due to the introduction of seed oil-derived allergens causing, especially in children, severe food allergy phenomena...

BACKGROUND: To minimize the risk of accidental reactions, atopic children with multiple sensitizations to tree nuts are advised to avoid all nuts. Multiple food challenges would be needed to confirm the clinical relevance, but are too burdensome to be practical. The usefulness of open mixed nut challenges in terms of safety, reactions during challenge, tolerance of the challenge material, effect on the elimination diet and satisfaction of the parents was evaluated. FINDINGS: Open mixed nut challenges were performed in 19 children with a previous negative hazelnut challenge and long term elimination diet for tree nuts...

BACKGROUND: Food challenge tests are the gold standard in diagnosing food allergy. Guidelines provide scoring systems to classify symptoms during challenge and typically recommend that challenges are considered positive when objective symptoms occur. However, currently no standard criteria for the definition of a positive challenge outcome exists and interpretation of food challenges mainly depends on clinical judgment. This study aims to assess inter- and intra-observer variability in outcomes of routinely performed peanut challenges in children...

There are two groups of dust mites, house dust mites (HDMs) and storage mites (SMs), that have been identified in the household environment. Both could induce airway inflammation through activation of innate and adaptive immunity and lead to asthma. In order to monitor environmental dust mite infestation, different methods can be used to detect their presence, such as the use of floating methods, monoclonal antibodies, and nanostructured biosensor. SM could be identified in the storage room, mainly in contaminated food such as mushrooms and corn starch...

INTRODUCTION: Asthma control is considered the major goal of asthma management, while many determinants of control are difficult to modify. We studied the association between respiratory infection episodes (RTIs) of various types and asthma control. METHODS: Cross-sectional data were used from children aged 4-18 years with physician-diagnosed asthma who participated in a web-based electronic portal for children with asthma, allergies or infections. Asthma control was measured using the Childhood Asthma Control Test (C-ACT) or the Asthma Control Test (ACT)...

Food allergy is a common condition that plays an important role in the pathogenicity and maintenance of atopic dermatitis (AD), however, must be carefully investigated before imposing a restrictive diet. The aim of this study was to evaluate the sensitivity to foods in patients with AD, correlating it with the severity of the disease and other possible associated factors. One hundred and eleven children (6-180 months of age) with AD were evaluated and later followed up at the Allergy and Clinical Immunology Division, Department of Pediatrics at FMABC...

Patients with allergies or intolerances and those requiring special diets are among the groups that require formulations with special excipients. When compounding preparations for this population, the suitability of dyes, flavorings, sweeteners, preservatives, gelatins, milk products, gluten, corn, soy, nuts, alcohol, chocolate, and other animal-derived ingredients must be considered. Unlike manufacturers of foods and nutritional supplements, pharmaceutical companies are not required to list certain ingredients of manufactured drugs, such as wheat...

BACKGROUND: Limited and contrasting data are available about risk factors for severe reactions during double-blind, placebo-controlled food challenge (DBPCFC). Knowing these risk factors would help to improve safety precautions and choosing the best setting for challenge. We assessed whether we could determine predictors for positive and severe food challenge outcome (FCO) with regular available patient data in children suspected for peanut allergy. METHODS: A retrospective study in children referred for DBPCFC with peanut was performed during a 3-year period...
