Filter by:Child food allergy represent 6 to 8% of child in industrialised country. Within this allergy, peanuts and egg allergy are one of the most common. Actually when there is a suspicion of food allergy, the OPT is the gold standard for the diagnosis. During the OPT we give increasing doses of the allergen to the patient and evaluate threshold causing a clinical reaction. This test is associated with a risk of strong allergic reaction and need a medical supervision. Standard allergy test, like skin test or specific IgE test, can't be use for the diagnosis of these allergy. Some publications demonstrate that these tests lack sensibility and specificity for child food allergy diagnosis. New tests have to be develop to diagnosis child food allergy without risks. The BAT is a cellular test able to evaluate the basophiles activation by specific allergen in vitro. This test allow us to evaluate more physiologically the sensitization of patients to an allergen. It is already used in drug allergy and it has been evaluated in infant milk allergy in an other clinical trial. In this study we want to evaluate the sensitivity of BAT to the diagnosis of child food allergy compare to the gold standard test OPT. We will evaluate the BAT on 140 children with food allergy and compare this results with the OPT at the same time. If the BAT results can predict the sensitivity of children to food allergen, it could limit the use of the OPT and reduce the risk of this test.
Food allergy is on the rise within the pediatric population. Having food allergy can cause medical, nutritional and psychological issues in those who suffer with it. Although making the appropriate diagnosis of food allergy is very important, properly diagnosing food allergy has been a challenge. Skin prick testing and food-specific IgE testing of the blood can give positive results that are false. Currently, Oral Food Challenges are the best way to diagnose a food allergy. Unfortunately, Oral Food Challenges are time consuming and may not be readily available to suspected food allergy sufferers. This study is designed to examine the effectiveness of an allergy-detecting blood test called IMMULITE 2000 manufactured by the study sponsor, Siemens.
The objective of this research is to evaluate the effectiveness of a handbook for parents of children newly diagnosed with food allergy. The handbook was developed to provide information and strategies to support families in effectively managing food allergies while maintaining positive quality of life. Parents of children newly diagnosed with food allergy (within the past year) will be randomized into either the treatment condition (handbook) or a control condition (management of food allergy as usual). Participants will complete study questionnaires online at three time points: baseline (this will be before receiving the handbook for the treatment group), post-intervention (2-3 weeks after baseline), and follow-up (2-3 months after baseline). Data will be analyzed for change on study outcome measures and satisfaction with the handbook. Parents in the control group will receive the handbook following the conclusion of their participation in the study.
Food allergy occurs when the immune system reacts against foods. The immune system is the part of the body that protects us from illness and germs, but it can also cause allergies. Peanut allergy occurs in 1 - 2% of people in the United States and other Western countries. There is proof that allergy to peanut is increasing. Allergic reactions to peanut can be severe and life threatening. The only way that you can prevent an allergic reaction is to avoid exposure to peanuts. However, peanut proteins are found in a variety of foods and people can be accidently exposed to peanut proteins. Treatment for accidental exposure include antihistamines (medications like Benadryl), and injectable epinephrine (adrenalin) which must be carried at all times. DBV Technologies has developed an epicutaneous delivery system, a patch that puts the peanut protein on the skin.
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 purpose of this study is to attempt to understand how desensitization works in peanut allergic children who are undergoing oral immunotherapy (OIT) to peanut. We want to identify the early changes in the desensitization process the immune cells undergo to become desensitized to the peanut protein.
Irritable bowel syndrome (IBS) sufferers often find that specific foods can exacerbate their symptoms; identifying which foods involves a long and arduous process. Different food allergy tests are marketed to IBS sufferers and healthcare practitioners as an easy way to identify these offending foods. Which test method might be best to use? This project compares the results of different food allergy methods versus an elimination/challenge diet to determine which method maybe superior in IBS sufferers.
