Filter by: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 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.
Our central hypothesis is that dietary limitations introduced by food allergy will contribute to increased food insecurity in households with food allergic children when compared to food insecure households without food allergic children.
The Polish Mother and Child Cohort is multicentre prospective study on different exposures. Prospective cohort study design enables identification of exposures that may influence pregnancy outcome and chil-dren's health, verification of such exposures by biomarker measurements and notification of any changes in exposure levels. The aim of the study is to evaluate the impact of exposure to different environmental factors during pregnancy and after birth on pregnancy outcome and children's health. Specific research hypotheses refer to the role of heavy metals, exposure to polycyclic aromatic hydrocar-bons (PAHs) and environmental tobacco smoke (ETS) in the aetiology of intrauterine growth retardation (IUGR), preterm delivery (PD) and the risk of respiratory diseases, allergy and poor mental and physical development. It is also intended to explain the role of oxidative stress and nutritional status of the pregnant women. The impact of occupational exposures and stressful situations on pregnancy outcome will be evaluated from question-naire data. The results of the study will help to determine levels of child prenatal and postnatal exposure in several areas of Poland and their im-pact on course and outcome of pregnancy and children's health. This protocol concerns the children that are followed-up from birth to the age of 2 years to determine long term effects of pre- and postnatal environmental exposures.
The purpose of this study is to compare Baked Egg vs. Egg Oral Immunotherapy for inducing sustained unresponsiveness to egg exposure in children.
In Finland, the estimated prevalence of physician-diagnosed food allergy in 1-4 year old children is 9%, and the most common allergen is milk. The overall food allergy has been reported to be 3.7%. Hen's egg allergy is among the most common food allergies in childhood. In addition, it predicts later development of allergic disease such as asthma. Most of the egg and milk allergy is transient and disappears in childhood. Currently, the standard of care for food allergy includes strict allergen avoidance. However, oral immunotherapy has been under investigation in children milk, egg, and wheat allergy. Previously, induction of clinical egg tolerance has been reported with egg oral immunotherapy in children aged from 3 to 13 years. In adults, strict avoidance is still the standard care but there is also growing interest in treatment of severe food allergy with oral immunotherapy or anti-IgE. The investigators aim to analyse the results of per oral immunotherapy treatment in severe IgE-mediated egg, milk, and nut allergy in adults. Could severe egg, milk and nut allergy be treated with oral immunotherapy treatment in stead of total allergen avoidance and could desensitization thus be achieved?
The investigators will perform a double blind, placebo controlled clinical trial with Xolair (omalizumab) at four centers to safely and rapidly desensitize patients with severe peanut allergy. The investigators will determine if pretreatment with anti-IgE mAb (Xolair/omalizumab) can greatly reduce allergic reactions and allow for faster and safer desensitization.
The objective of the study is to assess the prevalence of a sensitization to proteins from legumes by skin prick test using commercial extracts (peanut, soy, and pea) and raw material (lupin) in atopic and healthy subjects.
This study evaluates the diagnostic efficacy of CAP System (capsulated hydrophilic carrier polymer) for recombinant tropomyosin from shrimp extract in discriminating between subjects allergic to shrimp with CAP positive subjects allergic to mites, crustaceans asymptomatic but with a positive CAP to shrimp, to identify those at greatest risk of food reactions.
