Filter by:The proposed research project will evaluate a novel behavioral intervention that promotes early adolescent food allergy self-management and adjustment through 1) food allergy education, 2) problem-solving, communication, assertiveness, and anxiety management skill building, and 3) peer support.
Preventing food allergic reactions predominantly relies on allergen avoidance and managing this daily causes high anxiety in some patients, while having an allergic reaction can cause a post-traumatic stress disorder-like syndrome in children. The underlying mechanisms of these psychological changes are poorly understood, but one potential mechanism may be post-natal hippocampal neurogenesis (HN). HN is the production of new neurons from stem cells in the hippocampus which is one of the brain centres for memory and mood regulation. HN has been associated with cognitive function and some psychiatric disorders. Importantly, it can be influenced by both internal (bloodstream) and external (exercise, diet, etc.) factors. This study will explore the link between food allergy and children's mental health and cognition, and to determine whether this is linked to changes in HN.
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 Allergy (NAPFA) score is to develop a new clinical score including the main anamnestic, and clinical features for the easy identification of pediatric FA in primary care setting.
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe, but we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Fish Immunotherapy (FOIT), with codfish as the primary focus, in inducing tolerance in children with fish allergy compared with Placebo. Children will take increasing doses of codfish protein until a total of 12 months treatment is completed. Children will be tested for fish allergy at the start of the study, at the end of fish treatment T1 (12 months) and T2 (8 weeks) after treatment.
The main purpose of this study is to evaluate efficacy and safety of an amino acid-based formula Neocate Jr in children with food protein allergy, and to evaluate nutrition sufficiency of Neocate Jr in 1 to 10 years old children with food protein 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 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.
The study objectives are : Determine standards of plasma levels of casein-specific immunoglobulin G4 (IgG4) and egg-specific immunoglobulin G4 (IgG4) as a function of age, in non-allergic children, in allergic children, and in cured former allergic patients. Analyze the plasma IgG4 / IgE ratio, according to the result of the oral provocation test (tolerance versus allergy) and, in the event of a reaction, according to the reactogenic dose (dose which caused the reaction).Determine whether analysis of the plasma metabolome can identify children with a cured allergy to cow's milk protein or to egg from those with a persistent allergy.
The BAT II Study is a cross-sectional diagnostic study in which children with suspected IgE-mediated allergy to foods (namely cow's milk, egg, sesame and cashew), as defined by a history of an immediate-type allergic reaction to a food or no history of food consumption or the presence of food-specific IgE as documented by skin prick test or serum specific IgE, will undergo a diagnostic work-up to confirm or refute the diagnosis of IgE-mediated food allergy. Participants will be prospectively recruited from specialised Paediatric Allergy clinics in London and will undergo skin prick testing (SPT), specific IgE testing to allergen extracts and allergen components, basophil activation test (BAT) and oral food challenge. The diagnostic accuracy of the BAT and of other allergy tests will be assessed against the clinical gold-standard.
