Filter by:The investigators will conduct low-dose intranasal allergen challenges on children and young people with an indeterminate diagnosis of food allergy to cow's milk or peanut. Blood samples will also be taken, for conventional blood allergy diagnostics (allergy-specific Immunoglobulin E) and mast cell activation test (MAT). The data will be used to determine the diagnostic accuracy of two complementary, novel approaches to diagnose food allergy, in a representative clinical cohort.
This is an experimental, interventional study, following on from a clinical trial comparing the efficacy and safety of oral immunotherapy with low and high doses of sesame protein, in which patient desensitisation was achieved (High and Low Dose Oral Sesame Immunotherapy - Comparison of Efficacy and Safety, NCT05158413). The aim of this study is to assess a sustained unresponsiveness (SU) to sesame protein after at least 8 months of previously assigned high- or low-dose sesame OIT, followed by 4-week-allergen avoidance, and verified by an open oral food challenge (OOFC).
The goal of this clinical trial is to learn about oral immunotherapy in food allergic children < 30 months of age. The main question it aims to answer is: What is the clinical- and cost-effectiveness of early low-dose oral immunotherapy aimed at long-term tolerance induction. Participants will receive oral immunotherapy for 1 year with a maintenance dose of 300 mg allergenic protein and are compared with food allergic infants not receiving oral immunotherapy to compare with natural tolerance development.
This STRING study will examine markers of esophageal inflammation using a minimally-invasive testing device, the esophageal string test (EST). The primary objective is to determine the effect of omalizumab (Xolair) and dupilumab (Dupixent) on markers of eosinophilic inflammation in the esophagus of subjects treated with omalizumab-facilitated mOIT(mult-allergen oral immunotherapy) and/or mOIT with concurrent dupilumab.
The purpose of this prospective study is twofold: 1) to establish oral tolerance to selected tree nuts and to examine potential predictors of oral tolerance and 2) to determine the usefulness of mixed tree nut allergen food challenges in more efficiently defining tree nut allergy and oral tolerance.
The Study examines the molecular basis of food allergy. It explores the interaction between T cells, InKT cells and cytokines in the development of food allergy. The study also explores these factors in development of tolerance "outgrowing" food allergy. It will also explore the genetic factors that lead to the development of food allergy. The study examines all type of food allergy including IgE mediated reactions, Eosinophilic Esophagitis and Food Protein Induced Enterocolitis
Although some causal factors in allergy development such as allergen exposure and environmental pollution have decreased during recent years, the incidence of the allergic diseases has increased in the Western world. Since the genetic predisposition to develop allergies cannot change in such a short time it is conceivable that, instead of the emerging of some new and unknown risk factors, some protective factors seem to have disappeared in the Western world. Allergic disease is a tendency to develop allergies to allergens in the surrounding environment. The most common symptoms are eczema and food allergy in the early life, bronchial asthma (AB) later in childhood and allergic rhino conjunctivitis (ARC) during school age and adolescence, the so-called allergic march. Some person may develop only one, but others some or all of the symptoms. Inheritance, environment and allergen exposure are important factors affecting this march but there are important factors that predict later development of diseases. Sensitization to egg (positive skin prick test or specific IgE to egg in the serum) combined with skin problems in infancy predispose strongly to the development of allergic asthma in later life. The purpose of this work is to supply children with early development of IgE associated eczema and food allergy with omega-3 LCPUFA before the age of 12 months and assess the effect of the supplementation on the future development of skin symptoms, food allergy, sensitisation against inhalant allergens and asthma in these children. We will also assess immunological markers of Th2-skewed immunity in relation to clinical effect of the supplementation. Families with children younger than 12 months referred to the paediatric department at Linköping University Hospital, Motala, Norrköping and Jönköping Hospitals in the South East of Sweden, with the diagnosis IgE associated eczema and sensitised against food allergens (egg, milk, wheat and/or soya) will be invited to participate in this study. Clinical examination by a paediatrician and assessment of disease severity with SCORAD will be performed by a research nurse at inclusion. The children will be assessed every six months by a nurse until 2.5 years of age and by a paediatrician at 3 years of age. Later clinical assessment will be performed yearly until age 7.
