Filter by: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.
Infants/children with cow's milk allergy will take part in 2 double-blinded placebo-controlled food challenges (DBPCFC) of 2 extensively hydrolyzed formulas in random order. If both food challenges are passed, subjects will be asked to consume the Test formula in an at-home open challenge for 7 days.
In this study the investigators aimed to evaluate diagnostic accuracy the scoring tool used to determine cow's milk protein allergy, the cow's milk related symptom score, is based on the gastrointestinal, respiratory system and dermatological symptoms being together in young Turkish children.
The Cow's Milk-related Symptom Score (CoMiSS) tool has been developed to define a score to recognize cow's milk related symptoms in infants and young children. Many infants and toddlers with symptoms that can be related to intake of cow's milk and cow's milk protein allergy (CMPA) are often not diagnosed due to the lack of specific markers. The goal of this trial is to validate the CoMiSS tool in infants suspected of CMPA and investigate if the CoMiSS tool could be an alternative to the open challenge test needed to confirm the diagnosis of Cow Milk Protein Allergy.
Cow's milk protein (CMP) allergy is one of the most common food allergies and potentially a fatal one. Early feeding with CMP has been considered in the past as a risk factor for development of CMP allergy in high risk infants. Although other studies argue with this assumption and suggest early exposure to CMP might be protective against atopic dermatitis and CMP allergy. A cohort study that first introduction of CMP after 15-30 days of age, raised the risk for CMP allergy.The aim of this study is to investigate if early and continuous exposure to CMF will decrease CMP allergy rate.
Epigenetic mechanisms have been implicated in the pathogenesis of food allergy. The investigators previously demonstrated that tolerance acquisition in children with Immunoglobulin E- (IgE) mediated cow's milk allergy (CMA) is driven by epigenetic modulation of the Th1 and Th2 cytokine genes. A regulatory T cell (Treg) suppressive phenotype, characterized by stable expression of the transcription factor "Forkhead box Protein 3" (FoxP3), plays a pivotal role in food tolerance. FoxP3 mRNA expression is lower in children with atopic asthma or IgE-mediated food allergy than in healthy children. FoxP3 stable expression requires full CpG demethylation of its transcriptional regulatory regions, and, moreover, hypermethylation of the FoxP3 gene has been associated with reduced Treg function and allergy. DNA methylation is a biologically and chemically stable epigenetic modification that locks in long-term gene expression patterns. The demethylation status of FoxP3 at a highly conserved region within the Treg-specific-demethylated-region (TSDR), a CpG-rich, located on the 2nd conserved non-coding sequence of FoxP3 (CNS2), is restricted to Tregs. Transcriptional activity of the TSDR is essentially determined by its methylation status : it is completely inactive in its methylated state, but when the TSDR is demethylated, transcription factors such as Ets-1 and Creb can bind to the TSDR. TSDR demethylated and open chromatin conformation in the Foxp3 locus leads to stable phenotype differentiated Foxp3+ Treg. FoxP3 TSDR demethylation in peripheral blood mononuclear cells (PBMCs) has been associated with reduced atopic sensitization and asthma in children. Epigenetic regulation of antigen-induced T-cell subsets may predict a state of immune tolerance in food allergy. Indeed, DNA methylation of the FoxP3 gene in Tregs decreased during oral tolerance acquisition in patients with peanut allergy undergoing oral immunotherapy. The aim of this study was to evaluate further the epigenetic regulation of FoxP3 gene in children with IgE-mediated CMA.
To investigate the effect of baked milk in immunotherapy of cow's milk allergy.
Primary Endpoint -The percentage of subjects who develop tolerance to cow's milk protein by 12 months post randomization to study formula. Secondary Endpoints - Tolerance - The transcriptional profile of milk-specific T cells by clinical outcome. - Growth and Weight Velocity - Stool Consistency and Frequency - The estimated frequency of milk-specific T cells by clinical outcome. - The TCR diversity of milk-specific T cells by clinical outcome. - The milk allergen component-specific IgE, IgG4 and IgA by clinical outcome. - Safety - The rate of reported adverse events by treatment group.
The aim of this study is to assess the hypoallergenicity of a new thickened extensively hydrolyzed formula, in infants with confirmed cow's milk protein allergy assessed through a double blind placebo controlled food challenge, followed by a 3-month open feeding period.
This is a single-site, double-blind, placebo-controlled, randomized trial to study efficacy and safety of the Viaskin® Milk Patch for children with milk induced Eosinophilic Esophagitis (EoE). 20 subjects will be randomized 3:1 to Viaskin® Milk or placebo patch.
