Filter by:The purpose of this clinical study is to test whether patients with fish or shellfish allergy can ingest different types of fish oil supplements without having an allergic reaction. To achieve this, the recruited participants will be asked to: - provide a blood sample (used for Basophil Histamine Release Assay) - undergo a skin-prick-test - partake in multiple oral provocations These three tests will indicate the likelihood that the participants can consume fish oil supplements without adverse allergic reactions (See the detailed description for an explanation of the tests). The investigators will test the participants tolerance for three different types fish oil supplements: Fish oil, Cod liver oil, and krill oil.
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.
Food allergies account for only a small percentage of all adverse reactions to foods and their prevalence has increased over the past 10-15 years, particularly in industrialized countries: 3-6% of children under 3 years of age and 1-3% of adults. Food allergens in children are represented by milk, egg, wheat, soy, peanuts, tree nuts, fish, and shellfish. The majority of allergic processes that develop during the childhood tend to abate with age, whereas those that occur during adulthood tend to persist. Hypersensitivity refers to an excessive immunological reaction to food antigens with undesirable consequences. The first aim of our study is to evaluate the role of intestinal microbiota and their relationship with immune tolerance or allergic disorder. The second aim of our study is determining the biochemical metabolites on the host (human being) in allergic disorder, and these biochemical metabolites can be measured in fecal or urine samples by metabolomics methods. We try to seek to gain an advanced understanding of gut microbiota and biochemical metabolites associated with mucosal immune responses in the host. These findings could be useful for developing strategies to modify the gut microbiota or medical applications (e.g. healthy microbe preparations) involving beneficial microorganisms to control the development of allergic disorders.
Oral intake of nickel (Ni) is capable of causing the onset of systemic disorders in patients with Systemic Allergy to Nickel Syndrome (SNAS), an emerging allergic condition. Given its ubiquitous age, it is not possible to completely eliminate Ni and, therefore, it is necessary to plan a low-content diet. However, due to various factors (such as variability of Ni concentration in the soil, individual foods, variability of dietary habits and daily menus, different intake of Ni contained in the water, different intake of kitchen utensils, simultaneous intake of other substances), a restrictive diet is difficult and socially discriminating with a strongly negative impact on the quality of life of these patients. Hydroponic agriculture in a completely controlled, aseptic, artificial, soilless environment could be an alternative for patients suffering from SNAS with known and lower concentrations of metals than those deriving from conventional agricultural techniques, which are affected by the soil of origin and practices cultivation. The primary outcome of the study is to evaluate the possible effects of taking tomato puree deriving from hydroponic agriculture compared to tomato puree from conventional cultivation in the subjective control of SNAS symptoms, in patients following a low-diet diet. This is an interventional, randomized, double-blind, single-center crossover study involving a cohort of SNAS patients following a low-nickel diet for at least 4-6 weeks.
This interventional study aims to investigate the tolerance of organic formula milk on infants supplemented with organic formula milk. This study also observes gut microbiota, short chain fatty acids, nutritional status, and atopic manifestation on infants supplemented with organic formula milk. This study will be done on 50 subjects, with an age of 6-7 months old, 38-42 weeks of gestation, had a birth weight ranging from 2700 grams to 4200 grams, not suffering from any major congenital anomaly, not severely stunted at birth, has a normal thyroid function, not suffering any prominent gastrointestinal disease, not having a severe disease at the beginning of study, and has an approval from their parents. Participants' diet will be added an organic formula for infant for 3 months, and will be monitored regularly, since this study starts, at each month, and at the end of this study. The participants' gut microbiomes will be calculated at every session of monitoring by collecting their fecal samples, and brought to laboratory. Anthropological data (weight, height, body mass index), atopic manifestation, IL-6 and IL-10 will also be collected.
Objective: This Phase II STTR grant incorporated user feedback collected in an earlier development project to build interactive, web-based software that helps children with food allergies learn about their condition and gain self-management skills. This highly interactive game allows children to progress through virtual scenes to help them learn about food avoidance, symptom detection, and reaction management. In addition, this project built gaming complexity, with more levels and game options, of the two interactive games "Label Learning: Like it or Lose it!" and "Reaction Action!." Research Procedures: The researchers elicited input from 8 families of children (ages 8-12) with food allergies and their parents by presenting some of preliminary intervention materials (e.g., storyboards of a child in a family gathering involving food) in a focus group format. After that, up to 40 families of children with food allergies (ages 8-12) were recruited to participate in an "open trial". Families were asked to use the software for two weeks and provide feedback on the software. Up to 100 families of children with food allergies (ages 8-12) were then recruited to participate in a Randomized Clinical Trial (RCT) to assess the efficacy of the F3A-App vs. Standard Care (brief office visit and educational handouts). Families in the clinical trial were asked to use the software for two weeks and complete a standard care allergy office visit. This design enabled the investigators to evaluate combined effects of Standard Care and the F3A-App through typical treatment channels (e.g., is the greatest efficacy found after a physician refers family to use the App after an office visit?). Gains in families' knowledge and confidence in food allergy management were evaluated, and interviews with families were conducted to gain further input regarding the software's credibility, usability, and acceptability. This entry describes only the RCT portion of this Phase II STTR project.

Irritable Bowel Syndrome (IBS), or functional colopathy, is a chronic disease that affects 10% to 20% of the world's population.This syndrome is characterized by chronic abdominal pain or discomfort as well as a change in bowel habits (constipation or diarrhea) in the absence of structural or metabolic abnormalities (e.g. celiac disease, Crohn's disease). These symptoms have an impact on the quality of life of these patients who must therefore integrate the management of their disease into their daily life.IBS is subdivided into 3 subtypes according to the predominant symptom: the IBS-D subtype which groups together patients who have a predominance of diarrheal episodes, the IBS-C subtype which groups together patients who have a predominance of '' episodes of constipation and finally the IBS-M subtype which includes patients whose two symptoms mentioned above are observed without predominance
Food allergy is a potentially life-threatening condition, and its prevalence continues to increase despite public health efforts. There are currently no known therapies that can reliably prevent food-induced anaphylaxis. This is an open-label study designed to determine the ability acalabrutinib to prevent signs and symptoms of anaphylaxis during an oral food challenge in food-allergic adults.
This study aims to investigate the incidence of venous thromboembolism in people who are diagnosed with atopic dermatitis.
