Active clinical trials for "Food Hypersensitivity"

The Primary Objective of the study is to develop a customized regimen for oral immunotherapy that reflects what the subject is allergic in a clinically significant way (i.e., the offending food allergen is defined as a food allergen with a positive skin test or positive specific IgE and a positive DBPCFC). Therefore, the investigators prefer that both single and multiple food allergy subjects are included in the study.

The purpose of this study is to determine if treatment with omalizumab (Xolair, anti-IgE) can eliminate or reduce symptoms of peanut allergy.

Peanut allergy is known to cause severe anaphylactic reactions.The goal of this proposal is to produce a new treatment that would benefit young subjects who have recently been diagnosed with peanut allergy by lowering the risk of anaphylactic reactions (desensitization), and changing the peanut-specific immune response in subjects who have peanut allergy (tolerance).

The purpose of this study is to evaluate the safety and immune response to daily sublingual (under the tongue) immunotherapy (SLIT) with peanut extract in adults and children with peanut allergies.

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 influenced by both internal (bloodstream) and external (exercise, diet, etc.) factors. This study will explore the link between food allergy and children's mental health and cognition, and to determine whether this is linked to changes in HN.

Food allergy has been found to have a profound impact on parents of children with food allergy, with caregivers experiencing poorer psychological outcomes such as increased stress, anxiety, worry and depression than parents of non-allergic children. Furthermore, they report poorer quality of life (QoL) due to the psychosocial impact of looking after a child with food allergy, identifying the need for parental interventions aimed at improving these outcomes. There has generally been a paucity of research in this area, but there has recently been encouraging evidence to suggest that interventions involving Cognitive Behavioural Therapy (CBT) have the potential to improve the lives of those parents impacted by a child's food allergy. This study aims to add to this emerging evidence base by reporting on the feasibility of a brief, group CBT intervention for parents of children with food allergy. This small, proof of concept study also aims to report on a range of psychological measures to see if there is any evidence that this intervention may be effective in improving outcomes. Thirty to forty parents of children with food allergy will be recruited to the study and randomised to receive either a one-day or two half-day group CBT intervention or treatment as usual. Measures of a range of psychological outcomes, food allergy specific QoL and goal-based outcomes will be taken at baseline and at one and three-month follow ups. Participants will be asked for their feedback so that researchers can report on the acceptability of the intervention for those involved. This study is also interested in hearing about the parental experience of accessing psychological therapies as it is still not clear why some parents may require psychological intervention whilst others may not; participants in the intervention group will be invited to take part in interviews in order to share their experiences. It is hoped that this set of findings will help to determine if a brief group CBT intervention could be recommended for efficacy testing as part of a wider effort to provide evidence-based treatments for parents of children with food allergy experiencing poor psychological outcomes and poor food allergic-specific QoL.

This study is a randomized, placebo-controlled, single-masked (blinded), post-marketing clinical study of a drug Lactobacillus Reuteri NCIMB 30351 drops in functional disorders of gastrointestinal tract and skin symptoms of food allergies in children between the ages of one and four months inclusive. The aim of the study is to assess clinical effects of probiotics Lactobacillus Reuteri NCIMB 30351 drops on the symptoms of infantile colic, constipation, diarrhea, gastroesophageal reflux, atopic dermatitis/eczema in full-term newborns during the first months of life, laboratory parameters of microbiome will also be assessed. A prospective study comparing two treatment groups: Group 1 (treatment group) - 60 infants. Group 2 (control group) - 30 infants, placebo. The study drug will be taken in 1 time per day within 25 days. Allowed symptomatic therapy includes defoamers (simethicone-based preparations), carminative preparations (dill water (fennel)), etc.

ITN049AD (LEAP-On) Study is a continuation of the ITN032AD LEAP Study (NCT00329784). Peanut Allergy, a recognized public health concern, is a common and potentially life-threatening food allergy for which there is no treatment. ITN032AD (LEAP) Study evaluated whether early exposure to peanut promotes tolerance and provides protection from developing peanut allergy in children who are allergic to eggs or who have severe eczema. ITN049AD (LEAP-On) Study will evaluate persistent tolerance to peanut by assessing the effect of twelve months of cessation of peanut consumption in LEAP Study participants who consumed peanut and those who avoided peanut over the previous five years.

The aim of this study is to investigate the safety and tolerability of Subcutaneous Immunotherapy treatment (SCIT) with incremental doses of a modified recombinant fish parvalbumin (mCyp c 1) quantified in mass units: To establish a safe dose of the candidate hypo-allergen in human subjects and To study the pharmaco-dynamics of the hypo-allergen administered to human subjects. The study is performed as a placebo-controlled double-blinded randomized trial with 24 fish allergic patients allocated into three different groups of eight.

Primary Objective: To determine if 36 months of peanut SLIT as an early intervention in subjects ages 1 to 4 years induces clinical desensitization. The primary outcome of this objective will be a statistically significant difference in challenge scores between the treatment group versus the placebo group during DBPCFC (Double blind placebo controlled food challenge) performed after 36 months of peanut SLIT (desensitization). Challenge scores are measured by the amount of peanut protein participants are able to ingest successfully without symptoms of an allergic reaction. [Time Frame: Baseline, 36 months] Secondary Objectives: A secondary outcome of this objective will be a statistically significant difference in the challenge score of the treatment group versus the placebo group during the DBPCFC performed 3 months after discontinuing therapy (tolerance). To examine the change in immune parameters associated with peanut SLIT and the development of clinical tolerance. Through this objective, the investigators will seek to understand the molecular processes by which SLIT affects the immune system through evaluation of immune mechanisms in relationship to clinical findings of desensitization and tolerance. The investigators will delineate the impact of peanut SLIT on the subsequent cellular and humoral responses to peanut protein. [Time Frame: Baseline, 39 months]
