BAT Cow's Milk for the Replacement of the Food Challenge Test
The prevalence of children suspected of a cow's milk allergy is 17% in the Netherlands. Cow's milk diagnosis is based on a food challenge test However, this food challenge test is expensive, time consuming, risky, with waiting lists of several months. This waiting time results in unnecessarily long-term use of expensive hypoallergenic milk formula Therefore, there is a great need to introduce a better and faster diagnostic test for cow's milk allergy diagnosis in standard care. The in vitro Basophil Activation Test (BAT) is cheap, quick (result < 1 day, no waiting list), safe for the child and is a reliable alternative for the food challenge test to diagnose an IgE-mediated...

Baylor Infant and Toddler Biomarker of Nutrition Study
Young children rely on their foods and drinks for the nutrients they need to grow, like energy, protein, vitamins, and minerals. In addition to nutrients, there are substances in fruits, vegetables, milk and formula, called phytochemicals, that can support health. While researchers know more about the role of phytochemicals in adult health, researchers know surprisingly little about how phytochemicals can support health in young children. One group of phytochemicals are called the carotenoids. Carotenoids are responsible for the red, orange, and yellow colors in some fruits and vegetables. In adults, carotenoids can support visual function. Researchers also know that measuring...

Blood Samples for the Study of Peanut, Tree Nut and Other Food Allergies
Food allergies are now a major problem. These experiments involve getting blood from people with food allergies and from people without food allergies. The blood collected will be used to answer questions and find information about peanut and other food allergies. Samples will come from: - People signed up by the investigators at the University of Colorado Denver - University of North Carolina, Massachusetts General Hospital, Children's Hospital of Colorado and the Immune Tolerance Network (Benaroya Research Institute) where people have been treated for peanut allergies - University of North Carolina, Massachusetts General Hospital, National Jewish...

Boiled Tree Nut for Oral Immunotherapy in Food-allergic Children
As the global prevalence of food allergy steadily increases, tree nut (TN) becomes one of the main triggers of food-allergic reactions and food anaphylaxis. Since there is no effective cure, TN-allergic patients and their families must continue to live with this chronic, disabling condition while avoiding allergens and responding to allergic reactions with emergency treatment. An emerging experimental treatment for food allergy is oral immunotherapy (OIT). Tree nut OIT appears promising in preliminary studies but there are concerns about the high risk of adverse reactions to TNs used in the treatment. The rate of remission with TN OIT is also lacking. Identification of OIT regimes...

Brachyspira and Intestinal Allergy-like Immune Reactions in Patients With Irritable Bowel Syndrome (IBS)
The aim of this study is to define local immune responses in the GI tract to food antigens in IBS patients, with and without Brachyspira infection, using advanced imaging. We hypothesize that Brachyspira infection can cause IBS symptoms by inducing loss of oral tolerance to dietary antigens through development of food-specific intestinal immune reactions and subsequent development of visceral hypersensitivity. During this study, the investigators will perform either confocal laser endomiscroscopy (CLE) or colonoscopic antigen provocation test (COLAP) to test to which food items the participants react to. Furthermore, the investigators will perform rectal barostat examination and...

Canadian Anaphylaxis Network- Predicting Recurrence After Emergency Presentation for Allergic REaction
BACKGROUND: Anaphylaxis is the most severe form of allergy that rapidly affects multiple body systems and can be deadly. The highest incidence of anaphylaxis is in children and adolescents. In Canada, approximately every 10 minutes there is an Emergency Department (ED) visit for food allergy, and up to 80% of anaphylactic reactions in children are triggered by food. The ambiguity in how physicians manage anaphylaxis adds a huge burden to health care and further contributes to ED crowding. Current Canadian and international treatment guidelines universally recommend that all patients present to the ED for a prolonged period (6-24 hours) of in-hospital monitoring after initial...

Capsule Sponge Study in Eosinophilic Oesophagitis
Open pragmatic, descriptive single site study in adult patients with non-stenotic eosinophilic oesophagitis. To assess the clinical value of Capsule sponge in the assessment of treatment response in patients with known non-stenosing eosinophilic oesophagitis, as an alternative to gastroscopy in a real world setting. To assess patient preference for Capsule sponge or gastroscopy. All patients with non-stenosing eosinophilic oesophagitis who are reviewed in clinic that have not had reassessment of their oesophagus post treatment initiation or change in treatment will be offered Capsule sponge as an alternative to gastroscopy. A standardised clinical symptom questionnaire will...

Changes in Esophageal Distensibility With Proton Pump Inhibitors in Patients With Esophageal Eosinophilia: A Pilot Study
This pilot study will explore whether treatment of eosinophilic inflammation in the esophagus is associated with an improved distensibility of the esophagus. Furthermore, previous studies of the esophagus using EndoFlip only measured distensibility of the distal esophagus, specifically the distal esophagus and esophagogastric junction. Eosinophilia in EoE has been demonstrated to affect both upper, middle and lower esophagus. The aim is to measure distensibility both proximal and distal, before and after treatment.
