Filter by:The purpose of this study is to investigate differences of the bowel wall thickness visible in conventional ultrasound and bowel perfusion using quantitative Contrast-Enhanced Ultrasound in patients with Crohn´s disease in comparison with healthy controls and patients with food allergy.
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.
The objectives of this study are (i) to evaluate the efficacy of oral immunotherapy to pistachio by evaluating the daily oral tolerance of 2g pistachio, by evaluating the long-term tolerance of 15g pistachio (sustained unresponsiveness) and by decreasing pistachio-specific IgE, (ii) evaluating the efficacy of pistachio immunotherapy on cashew tolerance, (iii) and to evaluate the safety of pistachio immunotherapy.
This is a phase II randomized double-blind placebo-controlled trial that aims at evaluating the safety and tolerability of oral encapsulated fecal microbial transplantation therapy (MTT) in peanut allergic patients. In this research the investigators would like to learn more about ways to treat peanut allergies. The primary objective is to evaluate whether MTT with antibiotic pretreatment can increase the threshold of peanut reactivity during a double-blind placebo-controlled food challenge from <=100 mg peanut protein to 300 mg after 28 days of MTT /placebo therapy and 4 months post therapy initiation.
This is an extension study to evaluate the long-term safety and efficacy of ligelizumab in particiants who have completed a ligelizumab Phase III study in food allergy.
The aim of the study is to assess the prevalence of peanut, tree nuts, and sesame allergy in Polish children at high risk of food allergy. Additionally, the timing of the development of peanut, tree nuts and sesame allergy in the first three years of life in a high-risk population will be assessed.
Tree nut immunotherapy Route Assessment and DEvelopment (TRADE) is a randomized controlled trial that evaluates the efficacy and safety of sublingual immunotherapy and lower, more tolerable, doses of oral immunotherapy than currently in use.
The number of young children with food allergy, in particular with nut allergy, is increasing worldwide. A diagnosis of nut allergy can cause much anxiety in parents. They worry about their child being exposed to nuts in foods when outside the home. This anxiety can lead to these young children being restricted from taking part in normal childhood activities. Last year, the investigators conducted a study Recording accidental allergic reactions in children's and teenagers (ReAACT) in which they surveyed over 500 children with food allergy attending our clinic, in order to learn more about their participation in social activities and their practices in relation to eating outside the home. In the present study, the investigators wish to build upon these results through using the findings to develop a programme to help to lessen the fear and anxiety experienced by parents of young children with newly diagnosed nut allergy. The investigators imagine that knowledge of how other families with children who have food allergy participate in activities involving food outside of the home might help newly diagnosed families. The investigators would like to know if parents of young children newly diagnosed with nut allergy would benefit from hearing this information. In order to do this, the investigators have developed a short online programme that parents can take part in, in their own homes. Content will focus on the day to day social activities of children with food allergy, based on the findings of the REAACT study. To help the investigators to measure the effectiveness of this programme on reducing anxiety and improving quality of life, they are asking all volunteer participants to complete 4 questionnaires. Two of these questionnaires will ask a parent to indicate 1) the impact of their child's nut allergy on their quality of life and 2) on their child's quality of life. The third questionnaire will ask about their level of anxiety. The fourth questionnaire will ask about their emotions and the coping strategies they use in the context of their child's food allergy. Participants will be randomized into 2 groups. Group 1 will take part in the online education session along with the usual education provided by the allergy team. The questionnaires will be completed online using only a study identifier number. This will ensure anonymity throughout the study. The only personal information that will be asked is parent's age group, whether they are a mother or father, their child's age and gender and whether they have any other allergies. Two weeks following the online educational session, Groups 1 and 2 will again complete the online questionnaires. The research question is to determine if the online educational session is effective at decreasing anxiety and improving quality of life in parents of young children with nut allergy. The outcomes are health related quality of life and level of anxiety. It is hoped that the findings will positively support parents, children and their families in Ireland who are living and managing nut allergy on a daily basis.
The BAT Impact study is a prospective multicentre study in the UK using a biomarker-led study design to compare the incidence of adverse events (defined as allergic reactions during oral food challenges) in a randomized-controlled trial. Patients will either follow the standard-of-care (i.e. an oral food challenge in case of equivocal SPT/sIgE) or follow a basophil activation test (BAT)/mast cell activation test (MAT)-based strategy, i.e. patients with a positive BAT or MAT are dispensed of an oral food challenge (OFC) and patients with a negative BAT/MAT undergo an OFC.
Aim of the study is to improve the diagnosis of food allergy and hypersensitivity. Intestinal homogenates will be used to determine total IgE, specific IgE, tryptase, histamine and inflammation parameters (IFNgamma, TNFalpha). These data will be correlated with serum values and disease status. In addition, organoids from duodenal tissue will be isolated and cultured in vitro and stimulated with the major food allergens. The gene and protein expression will be checked to identify relevant biomarkers.
