Filter by:The purpose of the study is to test a food supplement to: - Show that the food supplement is well tolerated and safe to feed to infants; - Find out how often parents/caregivers feed their infants the food supplement; - Find out how parents/caregivers usually add the food supplement to infants' regular solid or liquid food; and - Learn what aspects of the food supplement are more or less attractive to infants and to parents/caregivers.
Comparison the result of skin prick tests and atopy patch test of lyophilized food extracts at different storage time (0, 3 and 6 months) after preparation
The goal of this study is to compare ten current and readily available FDA approved allergy skin prick devices to determine the most sensitive and specific product and methods used for the diagnosis of allergic disease. The primary outcome will be to determine the analytical sensitivity and specificity of all ten skin prick devices by measuring wheal and flare response to histamine and control diluent in 1mm increments. Secondary outcomes include comparison of skin prick technique, optimum histamine concentration, patient comfort, reproducibility, and the comparability of high-resolution digital images.
Primary Objective: To assess tolerability and safety of SAR439794 [peanut extract (PE) sublingual immunotherapy (SLIT) adjuvanted with Glucopyranosyl Lipid A (GLA)] after repeated sublingual (SL) daily administration in peanut allergic adult and adolescent patients. Secondary Objective: To assess pharmacodynamics of SAR439794 after repeated SL daily administration in peanut allergic adult and adolescent patients.
Activation of mast cells in the immune system is known to cause allergic reactions sometimes with severe systemic symptoms. The investigators have recently developed a blood-based mast cell activation diagnostic test in which levels of functional activation in-vitro in primary cultured mast cells generated from the peripheral blood of single individuals can be assessed. It is the hypothesis that the test can be used to predict the potential state of in-vivo mast cell activation in any individual based on the functional activation profiles exhibited by their cultured mast cells. The investigators now wish to translate their in-vitro findings in a pilot study to disease groups where mast cell activation is expected to be high. These include highly allergic individuals; those with chronic idiopathic urticaria; those with mastocytosis; and those with the mast cell activation syndrome. Furthermore, they will use the functional genomics approach to identify gene expression biomarkers that are correlated with such diseases. The results will be compared with data that have been collected from a cohort of healthy control blood donors.
The aim is to analyse the results of per oral immunotherapy treatment in severe milk, peanut or egg allergy in adults. This is the second part of the oral immunotherapy study in adults at Skin and Allergy Hospital. The diagnosis of food allergy is verified with positive history, skin prick tests, egg and milk allergen specific IgE (immunoglobulin E) antibodies. In addition, food allergy is verified with an open label (milk allergy) or blind (peanut and egg allergy) allergen specific challenge test. OIT (oral immunotherapy) is performed according to a detailed plan. Lung function parameters are followed before OIT and and a year after OIT.
Living with food allergy may result in anxiety and reduced quality of life. Food allergic patients and their families are often concerned about casual exposure with the offending allergen through skin contact or being near the offending food, which is actually very low risk. This concern can limit social activities and increase stress. The aim of this study is to provide a behavioral intervention consisting of having peanut/tree nut allergic patients hold a cup with a peanut or tree nut to which the patient is allergic to and touching it. The goal is to reduce anxiety about casual exposure to food allergens and improve quality of life for patients with food allergies and their families.
Assessment of the knowledge levels of restaurant personnel about food allergies. A structured questionnaire was given through a telephonic interview to evaluate the responses of the respondents.
The first 1,000 days of life, from the conception to 24 months, are crucial to achieve long-term health outcomes and represent a strategic period to intervene under prevention and public health perspective. Nutritional exposures during this critical period of life can influence the future disease susceptibility. Maternal diet during pregnancy has been linked to offspring overweight/obesity risk and it could represent a potential target for overweight/obesity prevention. The Mediterranean Diet (MD) is considered one of the healthiest dietary models, which impacts beneficially the gut microbiome (GM), providing high amounts of fiber, antioxidants polyphenols and vitamins, and a balanced ratio of essential fatty acids (ω6:ω3). Notably, the MD beneficial effects are due to the synergistic and interactive combinations of nutrients, and the modulation of gene expression through epigenetic changes. Unofrtunately, the MD mechanisms during pregnancy in the prevention of childhood overweight/obesity are not yet fully known.
Among the 15 million people with food allergies in the U.S., adolescents experience the highest risk of adverse events. Yet, there are few evidence-based strategies to improve food allergy management in adolescents. In a cohort multiple randomized controlled trial, this study will include two experiments to test the effectiveness of text message reminders and incentives to encourage epinephrine-carrying.
