Fish Oral Immunotherapy in Hong Kong Children
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe, but we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Fish Immunotherapy (FOIT), with codfish as the primary focus, in inducing tolerance in children with fish allergy compared with Placebo. Children will take increasing doses of codfish protein until a total of 12 months treatment is...

Food Allergy in the Brain
Preventing food allergic reactions predominantly relies on allergen avoidance and managing this daily causes high anxiety in some patients, while having an allergic reaction can cause a post-traumatic stress disorder-like syndrome in children. The underlying mechanisms of these psychological changes are poorly understood, but one potential mechanism may be post-natal hippocampal neurogenesis (HN). HN is the production of new neurons from stem cells in the hippocampus which is one of the brain centres for memory and mood regulation. HN has been associated with cognitive function and some psychiatric disorders. Importantly, it can be...

Food-Specific and Component IgE Threshold Levels That Predict Food Allergy in People With Elevated Total Serum IgE Levels and Atopic Dermatitis
Background: Atopic dermatitis (AD), also called eczema, makes skin dry, red, and itchy. People with AD are more likely to get a food allergy than people without AD. But some food allergy tests are not always accurate in people with AD. Researchers want to study if people are truly allergic to milk and/or peanuts. Objectives: To improve the ways doctors test for food allergy in people with AD. Eligibility: People ages 3 21 who have had AD; have a high total IgE level (an allergic antibody); might have a milk and/or peanut allergy; and are currently enrolled in another NIH study Design: ...

GERAP's Epidemiological Survey on Perioperative Hypersensitivity Reactions
Perioperative hypersensitivity reactions are still associated with significant morbidity and mortality despite early recognition and use of epinephrine. The epidemiology of these reactions evolves over time and changes with clinical practice. The main objective is to study the epidemiology of these reactions over a 10-year period, including patient phenotype, reaction phenotype and outcome of the allergic work-up.

Group CBT in Parents of Children With Food Allergy
Parents of children with food allergies that are medically established will be randomized to participate either in 6 one-hour weekly virtual Cognitive Behavioral Therapy (CBT) groups or to a wait-list group, and outcomes will be measured for anxiety, depression and quality of life. Possible benefits include improvement in psychological functioning and quality of life of families, as well as improved understanding of the use of group Cognitive Behavioral Therapy (CBT) for parents of children with medically established food allergies.

Growth, Allergy and Neurodevelopment in Infants on Hydrolysed Formula
Breastfeeding is the recommended diet for all infants during the first half of infancy and is associated with numerous health benefits. However, when breastfeeding is not possible, an infant formula is the only nutritive alternative. Formula-fed infants have a different growth pattern compared to breastfed infants. Studies have shown that the higher protein content in infant formula compared to breastmilk results in a more rapid weight gain and an increased risk of overweight and obesity in childhood. For this reason, both quantity and quality of protein in infant formulae have been optimized during the last decade, to better meet the ...
