Filter by: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 EAT Study showed a reduction in both sensitisation (to all foods) and clinical food allergy (to peanut and egg) among children who consumed allergenic food early compared with those who followed standard government feeding advice to exclusively consume breast milk for the first 6 months of life. The EAT-On Study aims to establish whether the effects seen at 3 years in the EAT study represent a delay in FA onset or sustained tolerance. EAT-On will also investigate the natural history (emergence and resolution) of FA in childhood; thus shaping dietary and management plans for allergic patients. Findings will inform future research and weaning recommendations for preventing FA.
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.
