Swedish Study of Immunotherapy for Milk Allergy in Children
This trial is a two-armed open randomized controlled trial in children aged 5-15 years with challenge proven Immunoglobulin E (IgE)-associated milk allergy.The purpose is to determine if oral immunotherapy with milk can induce tolerance to milk. The active intervention is intake of increasing amounts of fresh milk for six months followed by three years of maintenance treatment with milk. The control group continues their elimination (milk free) diet. The trial will recruit patients at ten pediatric departments in Sweden, coordinated by Umeå University. The primary outcome is milk tolerance (defined as a negative double-blind ...

Systems Biology of Early Atopy
The goal of this study is to establish a birth cohort that collects prenatal and early life biosamples and environmental samples and rigorously phenotypes young children for food allergy and Atopic Dermatitis (AD) to identify prenatal and early life markers of high risk for food allergy and AD, as well as biological pathways (endotypes) that result in these conditions. Primary Objectives: - To study the role and interrelationships of established and novel clinical, environmental, biological, and genetic prenatal and early-life factors in the development of allergic diseases through age 3 years, with an...

Targeted Elimination Diet in EoE Patients Following Identification of Trigger Nutrients Using Confocal Laser Endomicroscopy
Using confocal laser endomicroscopy (CLE), gastrointestinal allergic reactions to certain foods in the duodenum will be evaluated on a cellular level. After that, a personalized exclusion diet will be followed based on the CLE results for 6 weeks, sham-controlled, in a cross-over fashion. Gastroscopy with esophageal biopsies will be repeated after each diet.

The Clinical Impact of the Basophil Activation Test to Diagnose Food Allergy
The BAT Impact study is a prospective multicentre study in the UK using a biomarker-led study design to compare the incidence of adverse events (defined as allergic reactions during oral food challenges) in a randomized-controlled trial. Patients will either follow the standard-of-care (i.e. an oral food challenge in case of equivocal SPT/sIgE) or follow a basophil activation test (BAT)/mast cell activation test (MAT)-based strategy, i.e. patients with a positive BAT or MAT are dispensed of an oral food challenge (OFC) and patients with a negative BAT/MAT undergo an OFC.

The Efficacy and Tolerability of 12-weeks Treatment With Almond and Buckwheat Based Formula in Pediatric Patients With Active EoE
Eosinophilic esophagitis (EoE) is a chronic, relapsing, immune-mediated esophageal disease. Clinical manifestations in infants and toddlers generally include vomiting, food refusal, choking with meals and, less commonly, failure to thrive. The management of the disease includes dietary and pharmaceutical interventions, and the goal of the treatment should ideally be both the resolution of symptoms and the normalization of the macroscopic and microscopic abnormalities. Milk is the most common food trigger identified, followed by wheat, soy, and eggs. The aim of the study is to examine the tolerability of a new plant based formula made...

The Egg Up Trial - Testing a New Treatment Pathway for Infants With Newly Diagnosed Egg Allergy
The goal of this study is to test the safety and feasibility of a change in management approach for infants with newly diagnosed egg allergy. Infants with newly diagnosed egg allergy will have egg introduced via a gradual and graded home based approach known as an "egg ladder" supervised by a dietitian. The main questions this study aims to answer are how safe and feasible are home-based dietitian-led "egg ladders" as a treatment pathway to achieve tolerance of egg for newly diagnosed infants with egg allergy.

The Frequency of Beef Allergy in Children With Cow Milk Allergy
This study aims to determine the frequency of allergy to beef meat in children with allergy to cow's milk by serum measurement. Also, the study aims to assess the sensitivity and specificity of beef IgE in relation to gold standardized of elimination challenge test and to assess effect of eating of cooked meat on symptoms of allergy in those proven to have either CMA alone +/- beef allergy (by serology).

The Naples Pediatric Food Allergy (NAPFA) Score
Food Allergy (FA) is one of the most expensive allergic disorders in the pediatric age, and affecting up to 10% of children worldwide, it is recognized as a global health problem. The Oral Food Challenge (OFC) is the gold standard for FA diagnosis, but it is time-consuming, expensive, and potentially dangerous, as it can determine severe anaphylaxis. In addition, causing long-lasting impact on patient anxiety and mental health due to the physical duress and health risks involved with its application, OFC strategy is little applied in clinical practice with consequent diagnostic errors and delays. The goal of the Naples Pediatric Food ...

The Potential Role of Compounds Derived From Ultra-processed Foods in Pathogenesis of Eosinophilic Esophagitis
Eosinophilic esophagitis (EoE) is a chronic antigen-mediated inflammatory disease of the esophagus that affects both children and adults. The incidence and prevalence of EoE is rapidly increasing in Western countries with an estimated incidence of 6.6 per 100,000 person-years (95% CI, 3-11.7) in children and 7.7 per 100,000 person-years (95% CI, 1.8-17.8) in adults. Clinically, it is characterized by various symptoms related to esophageal dysfunction, including vomiting, regurgitation, feeding difficulties, epigastric heartburn, dysphagia, or food bolus impaction, and may cause growth retardation. Diagnosis is made on the basis of...

The Quality of Life of Mothers of Children With Food Allergy
Food allergy (FA) derives from an abnormal immunological response to dietary antigens. On the basis of the immunological mechanism, FA are divided into the following forms: IgE-mediated, non-IgE-mediated and mixed. Prevalence, persistence and severity of pediatric FA have significantly increased over the past 2 decades. The treatment of FA is based on a rigorous elimination diet and on the correct management of acute allergic reactions, induced by the accidental ingestion of food allergens, with antihistamines, cortisones and adrenaline. Ensuring a strict exclusion of the allergen from the diet can be problematic, with the risk of...
