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...

The Role of Bifidobacterium Intervention in Food Allergic Infants
Infant food protein allergy is the most common allergic disease in children, which can lead to infantile-specific dermatitis, intestinal inflammation, and so on. Dietary avoidance is a common strategy for food protein allergy in infants and young children. However, the hidden etiology of food protein allergy or multiple food allergies often leads to poor efficacy. The aim of this study is to observe the clinical effectiveness of Bifidobacterium intervention on food allergy.

The Role of Filaggrin Mutations and Sensitization Pathways in Allergic Rhinitis and Peanut Allergy
Caucasian male and female participants age 18 years of age and older will be enrolled in this study if they have known birch or peanut allergies or known to be non-atopic. Participants will undergo skin testing to confirm their allergies if not completed in the last 12 months. Medications and medical history will be captured with a focus on atopic disorders. Participants will undergo birch and peanut patch testing to assess penetration and if potential correlation exists with filaggrin genotyping and phenotyping. Blood samples will be drawn from participants and DNA isolated for genotyping of null mutations in filaggrin.

The Role of Food Sensitivity in Psoriasis
Psoriasis is a common chronic skin disorder that affects over 4 million people. There is no cure for psoriasis and treatment is directed at controlling patients' symptoms. The purpose of this study is to determine whether psoriasis patients are more likely to have food sensitivities than those patients without psoriasis. We will also determine if eliminating certain foods from the diet results in a change in psoriasis symptoms.
