Use of Dexamethasone in Prevention of the Second Phase or a Biphasic Reaction of Anaphylaxis
Anaphylaxis is an acute serious allergic reaction, with multi-organ system manifestations caused by the release of chemical mediators and it is potentially fatal . Between 5% and 14% of patients may experience a recurrence of anaphylaxis 8-12 hours after the initial presentation, called biphasic (late-phase) . The mainstay of treatment for children experiencing anaphylaxis remains adrenaline and H1-antihistamines. Corticosteroids are not life-saving and do not have an immediate effect on the symptoms of anaphylaxis but may help reduce or prevent a biphasic "late phase" reaction . The aim of this study is to compare the efficacy...
Use of Esophageal String Test to Understand Symptoms, Inflammation, and Function in Eosinophilic Esophagitis
Presently, the only method available to monitor disease activity in Eosinophilic Esophagitis (EoE) is endoscopy with pathological review of biopsies. The overall goal of this study is to determine the ability of the Esophageal String Test (EST), a minimally invasive capsule based technology, to measure disease activity in children with EoE. Additionally, to determine esophageal distensibility in children presenting with EoE by using the EndoFLIP (functional luminal imaging probe) device during endoscopic procedures.
VE416 for Treatment of Food Allergy
This is a single-center, randomized, double-blind trial with four arms evaluating VE416 as pretreatment or concurrent treatment in comparison to low-dose peanut oral immunotherapy (PNOIT) alone.
Virtual Reality Technology Versus Standard Technology During Pediatric Oral Food Challenge
The purpose of this study is to determine if non-invasive distracting devices (Virtual Reality headset) are more effective than the standard of care of utilizing existing technologies that are currently more common in food allergy research treatment and clinics (i.e. television and patients' personal electronic devices) for decreasing levels anxiety and fear in pediatric patients undergoing oral food challenge (OFC) and their caregivers.
Adjuvant Treatment With Abatacept to Promote Remission During Peanut Oral Immunotherapy
This is a phase 2a, multi-center, randomized and double-blind placebo-controlled trial comparing 24 weeks of abatacept versus placebo used as adjuvant to oral immunotherapy to induce remission in adolescents and adults with persistent severe peanut allergy. This is a proof-of-concept trial in which the primary outcome will be the suppression of the initial peanut specific IgE surge during OIT, which is used as a proxy outcome of peanut allergy remission. Adolescents and adults with persistent severe peanut allergy (n=14) will be randomized to either abatacept or placebo at a ratio 1:1 for a total period of 24 weeks. Peanut oral ...
Advanced Multimodal Wireless Vital Signs Monitoring for Patients With Asthma and Anaphylaxis
The primary objective of this study is to assess the function and reliability of a non-invasive, skin-like electronic sensor. We hypothesize that this skin sensor will address an unmet need to wirelessly, noninvasively, and rapidly assess critical vital signs and other measures essential to healthcare monitoring for patients with asthma and anaphylaxis.
Allergy to Almond in Children
Allergy to tree nuts are frequent in children but allergy to almond is one of the less described tree nuts allergy. The main objective of our study is to determine diagnostic values of skin prick-tests and specific IgE to almond in a population of children sensitized to almond and challenged in our unit from november 2013 to march 2020.
Alpha-gal Pork Challenge
This study is investigating the hypothesis that alpha-gal is responsible for the gastrointestinal symptoms that occur in some alpha-gal syndrome subjects following the consumption of mammalian meat. This will be tested by comparing symptoms and immune responses in subjects with alpha-gal syndrome following consumption of "wild-type" pork (which contains alpha-gal) versus consumption of a novel pork product which has been genetically modified to lack alpha-gal (GalSafe pork from Revivicor Inc.).
Diagnosis of Cow's Milk Protein Allergy
The study will assess the diagnosis of cow's milk protein allergy (CMPA) among infant and children in assiut university children hospital using skin prick test and specific serum IgE as well as their management.
Dietary Factors and Disfluency: A Look Into Food Allergies and Other Environmental Triggers Associated With Variations in Severity of Vocal Cord Tension.
The purpose of this study is to see whether participants with persistent developmental disfluency who report fluctuational disfluency due to vocal cord tension on a day to day basis of can achieve a more normalized fluency by identifying dietary allergen responses and subsequently eliminating these dietary triggers from their daily consumption.
