Gradual Egg-tolerance Induction in Hen's Egg Allergic Children Who Tolerate Baked Egg (TETI-II Study)
The investigators want to test the hypothesis that a total period of 12 months of stepwise open egg introduction is not inferior when compared to a total period of 20 months gradual open egg introduction of a certain egg product with regard to full egg tolerance induction.
Grass Pollen Immunotherapy Plus Dupilumab for Tolerance Induction
The primary objective of this study is to assess whether the combination of grass allergen sublingual immunotherapy (SLIT) and dupilumab for 2 years is more effective than double placebo in suppressing the nasal allergen challenge (NAC) response to grass pollen at 1 year after completion of study medication.
High and Low Dose Oral Peanut Immunotherapy - Comparison of Efficacy and Safety
In this trial the investigators aim to assess the effectiveness and safety of oral immunotherapy with peanut protein in high and low dose (300mg versus 150mg) in children with peanuts allergy.
Hymenoptera Venom Immunotherapy: Evaluation of Its Long-term Efficacy at the University Hospital of Angers (EFLOTITA2)
Allergy to Hymenoptera venom is one of the main causes of anaphylaxis in adults, and is less common in the paediatric population. It can be severe or even fatal. Despite the use of an emergency kit, including an adrenaline auto-injector (AAI), at present only hymenoptera venom immunotherapy (VIT) is effective in preventing subsequent severe systemic reactions. Recurrence during the 5 years following cessation of VIT is about 10-15 percent. Studies evaluating longer-term efficacy are scarce. At the University Hospital of Angers, hundreds of patients are treated each year, and its allergology unit has been providing VIT...
Identification of Autoantigens in EGPA and Severe Eosinophilic Asthma
In this project the investigators will look for auto-antibodies to relevant proteins both in native form and importantly in post-translationally modified forms. Potential modified auto-antigens are eosinophil proteins (analogous to the cytoplasmic neutrophil proteins identified in vasculitides such as Granulomatosis with Polyangiitis (formerly known as Wegener's granulomatosis) and alternatively structural proteins such as collagen V. As well as advancing the understanding of asthma pathology, identifying a serum auto-antibody that could then be used as a clinical blood test, analogous to anti-cyclic citrullinated peptide (CCP)...
Immune and Clinical Implications of Threshold-based Phenotypes of Peanut Allergy
The primary objective of this study is to determine whether allowing ingestion of sub-threshold amounts of peanut in those with a high threshold (tolerate at least 143 mg peanut protein on supervised double-blind, placebo-controlled oral food challenge [DBPCFC]) will be associated with attaining even higher thresholds over time in children with high threshold peanut allergy compared to those avoiding peanut. The secondary clinical objectives include assessing the development of sustained unresponsiveness (SU, a surrogate term for tolerance without daily ingestion), effects on quality of life, and safety compared to those avoiding...
Immunological Response After Shrimp Oral Immunotherapy Treatment
Oral immunotherapy is effective in desensitized food allergy. Shrimp allergy is increasing in Thailand. So the purpose of our study is to determine level of specific immunoglobulin E antibodies to shrimp, Immunoglobulin G4 and immunoblot analysis in shrimp allergy patients after shrimp oral immunotherapy.
Improvement of Foodallergy Diagnostic in Gastrointestinal Tract
Currently, diagnostic possibilities for the detection of food allergy in the gastrointestinal tract are scarce. The endoscopic segmental Lavage is the method of choice, but it´s controversial. Additional to the endoscopic segmental lavage fluid a cytobrush is used for collecting the mucosa cells and biopsies are taken. Comparative to the Lavage specific IgE antibodies, Tumor necrosis factor- alpha, Eosinophilic cation protein and mastcell tryptase were measured.
Indiana University Gastrointestinal Motility Diagnosis Registry
Develop a registry (list of patients) with accurate clinical motility diagnosis. This registry will help the doctors to identify the patients with specific disease conditions. It will also help in promoting future research in gastroenterology motility disorders
Infant Formula Feeding and Necrotizing Enterocolitis in Newborns
Necrotizing enterocolitis (NEC) is the most common life-threatening gastrointestinal emergency of prematurity, associated with a significant morbidity and mortality. Early diagnosis and early treatment interventions may reduce the risk of mortality and morbidity. The Primary goal of this observational study is to gather survey data to establish a national database of NEC in newborns in order to better understand the risk factors underlying NEC. Survey data will be used along with a medical history to identify the mechanism(s) underlying the increased prevalence of NEC in non-breast fed, formula fed premature infants.
