Filter by:Accurate diagnosis of food allergy depends on the identification of the causative allergenic molecule(s). The proposed study intends to investigate and compare the pattern of IgE antibody sensitisation in walnut allergic subjects from three different regions of Europe (south (SEU) and central/north (C/NEU), to evaluate the diagnostic utility of a panel of novel allergen reagents.
The purpose of this study is to investigate the dose of a probiotic supplement (Bifidobacterium longum subsp. infantis) required to achieve predominant gut colonization in healthy newborn, breastfed infants. The study will also examine whether supplementation with this probiotic can reduce the chance of developing eczema and food allergies in enrolled infants.
The objectives of this study are to evaluate the safety and efficacy of Viaskin Milk after 12 months of epicutaneous immunotherapy (EPIT) treatment, for desensitizing IgE-mediated cow's milk allergic children and to assess the long-term safety and therapeutic benefit with Viaskin Milk.
Allergy to cow's milk is the most common food allergy affecting children. There is currently no accepted routine clinical therapy to cure milk allergy. Recently studies have attempted to induce desensitisation using small daily doses of cow's milk, predominantly by the oral route (oral immunotherapy, OIT). Although this therapy works for some people, its effects are not generally long lasting and it is associated with significant side effects during protocol, including potentially life-threatening allergic reactions. Pilot data suggests that sublingual immunotherapy (SLIT, where allergen is held under the tongue, rather than swallowed) can also induce a degree of desensitisation, but with fewer adverse events. However, the degree of desensitisation induced appears to be lower than that with oral immunotherapy. The investigators wish to determine whether a sublingual pretreatment phase can improve the safety of conventional OIT in cow's milk allergy.
The purpose of this study is to assess the responses in the immune system of infants after they receive the vaccine against diphtheria, tetanus, and pertussis (DTaP). The investigators will do this by studying the immune cells and allergy responses in the blood prior to and after receipt of the third DTaP vaccine.
Purpose of this study is to determine whether NAET procedures are effective in the treatment of crab or shrimp allergy. Hypothesis: experimental group will show a significant improvement over the control group in allergic symptom, serum crab- or shrimp-specific IgE and skin test for crab or shrimp extract.
Food allergies are now a major problem. These experiments involve getting blood from people with food allergies and from people without food allergies. The blood collected will be used to answer questions and find information about peanut and other food allergies. Samples will come from: - People signed up by the investigators at the University of Colorado Denver - University of North Carolina, Massachusetts General Hospital, Children's Hospital of Colorado and the Immune Tolerance Network (Benaroya Research Institute) where people have been treated for peanut allergies - University of North Carolina, Massachusetts General Hospital, National Jewish Health and The Children's Hospital in Denver where people have taken part or will take part in clinically indicated oral food challenges. Blood and health histories from the University of North Carolina, Massachusetts General Hospital, National Jewish Health, The Children's Hospital and the Immune Tolerance Network will not have personal information linked. The specific aims of this experiment are: 1. Come up with a lab test that will predict how bad an allergic reaction will be to peanuts. 2. Find out what part of a peanut causes allergic reactions. 3. Come up with preventions that can block peanut allergies. 4. Find the strongest proteins in walnuts.
The investigators will conduct low-dose intranasal allergen challenges on children/adolescents with a diagnosis of food allergy to egg/cow's milk/soya/wheat/peanut. The data will be used to determine the safety and potential utility of intranasal food challenges in the diagnosis of food allergy.
We report that Australia has the highest prevalence of Immunoglobulin(Ig)E-mediated food allergy in the world, with 10% of infants having challenge-proven food allergy in Melbourne. There has been a 5-fold increase in hospital admissions for life-threatening anaphylaxis. These changes are most pronounced in children less than 5 years, suggesting a causal role for early life determinants. We have primary data to inform hypotheses for the rise in food allergy, which appears to result from potentially modifiable factors related to the modern lifestyle, particularly Vitamin D insufficiency (VDI). We propose an intervention study to assess if infant Vitamin D supplementation during the first year of life significantly decreases the risk of early-onset food allergy and other allergic disease at 12 months (part 1) and 6 years of age (part 2). Australia is ideally placed to answer this important question since, unlike the USA, Canada and Europe, there are no population recommendations for routine infant supplementation with Vitamin D and we are one of the few developed countries that do not supplement the food chain supply with Vitamin D.
The purpose of the study is to determine whether therapeutic education can improve the quality of life of the child from 8 to 12 years old suffering of food allergy. This study also show us if therapeutic education has an effect on the quality of life of child's family.
