GERAP's Epidemiological Survey on Perioperative Hypersensitivity Reactions
Perioperative hypersensitivity reactions are still associated with significant morbidity and mortality despite early recognition and use of epinephrine. The epidemiology of these reactions evolves over time and changes with clinical practice. The main objective is to study the epidemiology of these reactions over a 10-year period, including patient phenotype, reaction phenotype and outcome of the allergic work-up.
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.
Group CBT Intervention for Parents of Children With Food Allergy
Food allergy has been found to have a profound impact on parents of children with food allergy, with caregivers experiencing poorer psychological outcomes such as increased stress, anxiety, worry and depression than parents of non-allergic children. Furthermore, they report poorer quality of life (QoL) due to the psychosocial impact of looking after a child with food allergy, identifying the need for parental interventions aimed at improving these outcomes. There has generally been a paucity of research in this area, but there has recently been encouraging evidence to suggest that interventions involving Cognitive Behavioural Therapy...
Growth and Plasma Amino Acids in Infants With CMPA and Treated With a Newly Innovated Amino Acid Formula
The purpose of this study is to determine growth and protein status of infants with cow's milk protein allergy and treated with a newly innovated amino acid formula compared to those with a commercial amino acid formula.
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.
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: A Pilot Study
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.
Improved Diagnostics of Celiac Disease in Children
The main purpose of this study is to improve the diagnostics of celiac disease and reduce the need for invasive endoscopic studies in children. Further, the investigators aim to investigate the natural history and risk of complications in children with celiac disease or gluten sensitivity and to create a large scientific database.
