Prospective Multicenter Nationwide Registry of Children With Eosinophilic Esophagitis
1. Registry of demographic, clinical, endoscopic and histological data at baseline. 2. Registry of patients treated with PPI: - Clinical, endoscopic and histological response at 8-12 weeks of induction treatment - Clinical, endoscopic and histological response at 6 and 12 months weeks of maintenance treatment 3. Registry of patients treated with two foods elimination diet: - Clinical, endoscopic and histological response at 8-12 weeks of induction treatment - Identification of food trigger: milk, gluten or milk and gluten - Clinical, endoscopic and histological response at...
Prospective Study About Sensitization Pattern to Insects as Food Source in Patients With House Dust Mite Allergy
Patients allergic to seafood and/or sensitized to Tropomyosin of SPT or crustacean origin will may be also be sensitized to edible insects. Aim of the study is to evaluate whether patients allergic to seafood and/or sensitized to Tropomyosin of SPT or crustacean origin may be more often be sensitized to edible insects used as food source.
Protection From Food Induced Anaphylaxis by Reducing the Serum Level of Specific IgE (Protana).
Anaphylaxis elicited by accidental intake of the offending food constitutes a major health risk to the food allergic patient. Current advice for the food allergic patient is to avoid the offending food allergen and to carry an epinephrine autoinjector. However, novel treatments altering the clinical reactivity to the offending food thereby diminishing the risk of anaphylaxis are much needed. A correlation between the level of specific IgE in serum towards the offending food and the clinical sensitivity of the patient has been suggested. The clinical threshold for a food allergic reaction to occur is therefore hypothesized to increase by...
Proton Pump Inhibitor (PPI) Response in Eosinophilic Esophagitis Assessed by Transnasal Endoscopy (TNE)
This study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE). Upon study enrollment, the participant will begin a proton pump inhibitor (PPI), Omeprazole 20mg twice daily. After taking Omeprazole for four weeks, the participant will have a Transnasal Endoscopy, and biopsies will be taken to determine the histological change. If the biopsies are abnormal, the participant continues Omeprazole and will undergo another endoscopy at eight weeks. The study aims to determine the percentage of children with Eosinophilic Esophagitis who improve with PPI use and to determine the length of time and effectiveness of...
Radiation Dose in Humans From Orally Administered Tc99m-Heparin
This is a research study of a new agent used for evaluation of inflammation in the GI tract. This agent is investigational and thus is being studied to determine appropriate dosing and administration in both normal controls (i.e. people without gastrointestinal complaints) and patients with eosinophilic disease (i.e. those with an immune reaction and inflammation in their bodies with a certain cell called an eosinophil). The study will test whether the radiolabeled agent will bind to the inflammation of eosinophilic esophagitis patients because an animal model of eosinophilic esophagitis which shows the striking deposition of eosinophil...
Randomized Placebo-controlled Study of L. Reuteri NCIMB 30351 in GI Functional Disorders and Food Allergy in Newborns
This study is a randomized, placebo-controlled, single-masked (blinded), post-marketing clinical study of a drug Lactobacillus Reuteri NCIMB 30351 drops in functional disorders of gastrointestinal tract and skin symptoms of food allergies in children between the ages of one and four months inclusive. The aim of the study is to assess clinical effects of probiotics Lactobacillus Reuteri NCIMB 30351 drops on the symptoms of infantile colic, constipation, diarrhea, gastroesophageal reflux, atopic dermatitis/eczema in full-term newborns during the first months of life, laboratory parameters of microbiome will also be assessed. A...
Reduction of Peanut Reactivity and Immune Modulation With Anti-IgE Therapy
This pilot study is will examine the pathways involved in allergic response, primarily in food allergy; specifically peanut allergy. We will also study non-allergic donors as well as patients with atopic disorders, primarily as control subjects. We believe that this study will lead to discovery of significant pathways involved in the allergic pathway that can be explored in more detail during follow-up studies in order to address mechanistic questions that cannot be answered in a pilot trial. We believe that such a pilot study represents the ideal approach to identify effective therapeutic interventions and to simultaneously better ...
Registry for Eosinophilic Gastrointestinal Disorders (REGID)
Develop Registry tool
Registry of Food Allergy Oral Immunotherapy Treatment
The purpose of this patient registry is to demonstrate safety and efficacy of food oral immunotherapy in food allergic patients. Factors that lead to adverse reactions will be identified. The frequency of rescue epinephrine use will be recorded.
Re-Introducing Nuts in Allergic Patients
This study aims to compare the safety and the compliance to different procedures (A: at home or B: at the hospital) for introducing tree nuts into the diet of patients with Immunoglobulin E (IgE)-mediated allergy to the aforementioned nuts. In parallel, the effectiveness of tree nuts' introduction in respect to tolerance induction compared to the standard care (strict avoidance of tree nuts) will be evaluated.
