Filter by:Peanut allergy is the most common cause of fatal and near-fatal food-allergic reactions and egg allergy is among the two most common causes of food-induced anaphylaxis. The proposed research will explore the development of sensitization to these food(s) in infants based on maternal consumption or avoidance during pregnancy and breastfeeding.
Fenugreek or Trigonella foenum greacum is an ancient medicinal plant native to the eastern Mediterranean, later spread to Asia (especially in India); it belongs to Rosaceae order, Leguminosae family, subfamily of Papilonaceae and it is used as a medicinal herb, spice or food. It is a component of spice mix, such as curry, and it is also used as a supplement in wheat and corn flour for bread-making. Fenugreek appears to have many health benefits and potential medicinal properties (antioxidant, antidiabetic, hepatoprotective, hypocholesterolemic, antimicrobial, anti-inflammatory, neuroprotective, anticarcinogenic, antiulcer, and antilithigenic) both in vitro and in vivo studies; for this reason it may be increasingly being used as nutraceutical formulations (powder, herbal teas, tablets and various combinations).This study aims to describe patients who came to our operating unit for suspected adverse reaction after ingestion of fenugreek and to highlight possible cross-reactivity between fenugreek and other legumes or other foods. Given the increasing use of novel spices in Mediterranean cuisine and the possible spread of fenugreek-based nutraceuticals, it is relevant to draw attention to possible allergic reactions.
Children with Food Allergy (FA) are at risk of life threatening reactions. They must carry an emergency medicine kit containing adrenaline auto-injector devices for the immediate treatment of anaphylaxis. Much research has documented the adverse impact of childhood FA on the food allergy related quality of life (FQoL) of the Carer and the family, along with reported higher levels of anxiety and stress. These adverse impacts are largely driven by the need for Carers to always be "emergency ready". Mothers of food allergic children report higher levels of anxiety compared to the rest of the family, possibly due to mothers commonly being the primary care givers responsible for the preparation of meals, childcare etc. Carers of newly diagnosed food allergic children, looking for more information about their child's FA are at risk of exposure to myths and misinformation about food allergy. These falsehoods are likely to increase further, Carers Food Allergy-related anxiety. The investigators wish to survey the frequency with which common myths on FA are believed among mothers prior to their attendance at an allergy clinic. They wish to understand the impact of "myth-busting" information on maternal anxiety or self-efficacy when provided to mothers while awaiting a specialist appointment. The research question is to determine if the online educational session is effective at decreasing anxiety and improving quality of life in Carers of FA children awaiting a specialist appointment.
The goal of this observational study is to learn about repetitive anaphylactic reactions in food allergic patients and to compare the frequency of repetitive reactions between different elicitors in food allergic patients. The main question it aims to answer are: • Is there an elicitor specific difference in the occurrence of anaphylactic reactions once the elicitor has been identified and the patient received counselling about its avoidance? Participants will answer questionnaires via a link they will receive via e-mail at baseline and 3, 6, 12 and 24 months after inclusion in the study.
Gibberellin-related proteins (GRPs) are proteins contained in both pollens and vegetables and are associated with an increased risk of severe food allergy reactions. The best characterized one the only one for which a specific IgE (Immunoglobulin E) may be dosed in current clinical practice is Pru p 7, an allergen contained in peaches (Prunus persica). Sensitization to GRPs seems to be greater in areas with high exposure to pollens of the Cupressaceae family (as in the Montpellier region in Southern France); a subtype of Cupressaceae pollinosis, characterized by sensitization to Pru p 7 has been shown to be responsible for severe peach allergies. To date, there has been no real analysis of the prevalence of sensitization to GRPs, or of possible cross-sensitization between plants and foods containing GRPs. Main food containing GRPs with a high level of homology with Pru p 7 include apples (Malus domestica, 97.3%), sesame (Sesamum indicum, 91.9%), carrots (Daucus carota subsp. Sativus, 88.9%), lemons and oranges (different species, with a homology of 87.3%). If investigators consider that sensitization to GRPs could be associated with severe allergic hypersensitivity reactions, it is important to detect the prevalence of sensitization to these allergens and to find sensitization profiles for these patients in order to gain a better understanding of this type of allergy and offer a more appropriate and preventive management to allergic patients. This remains today a major challenge for the allergy community in the Mediterranean region. This study aims to investigate the rate of sensitization to peach and 5 other allergens containing gibberellins, chosen on the basis of their homology with Pru p 7 (the gibberellin from Prunus persica): carrot, lemon, orange, apple and sesame.
The purpose of this study is to develop a microarray-based diagnostic test system for the determination of allergen specific IgE in human blood serum.
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.
For Patients diagnosed as cow milk protein allergy: Elimination of cow's milk products (CMPs) for 6 months. All infants were supplemented with Amino Acid-based Formula (AAF) (Neocate infant®/ Neocate junior®, Dannone Nutricia) for 6 months at start of elimination diet. For mixed milk fed infants (still receiving breast milk with the formula), mothers were encouraged to continue breast-feeding while avoiding all milk and milk products from their own diet. Intervention after completing 6 months of eliminating CMPs. The included patients were randomly assigned to one of (2 groups). 1. Group I (AAF group) n= 50 Infants in this group continued with Amino Acid-based Formula for another 6 months. 2. Group II (pHF group) n= 50 Infants in this group were shifted gradually to Partially-hydrolyzed whey formula (pHF) (Liptomil Plus HA infant formula. for another 6 months with continuation of elimination of cow's milk products. They were followed up for manifestations of intolerance to pHF. Infant who showed manifestations of intolerance were returned to AAF and continued for 6 months with AAF. Final step: Reintoduction of CMPs After 12 months of elimination of CMPs, evaluation of tolerance to whole CMPs was done by oral food challenge (OFC). For infants who were still non-tolerant to CMPs after 12 months of elimination were followed up and re-challenged after 6 months.
The evaluation of the quality of life (QOL) in food allergy (AA) is difficult due to the lack of a currently validated questionnaire. There are only a few tools available to assess the impact of nutritional care on the QOL of the allergic patient . Available questionnaires are poorly adapted to studies dealing with large cohorts where functionality and ease of use are determining factors. The aim of this work will be to develop and validate QOL questionnaires for AA, short and easy to use, also integrating the theme of collective catering in order to assess the evolution of QOL in patients with food allergy. The target population of the questionnaires will be: i) the parents of allergic children 0 to 17 years (15 questions) ii) allergic children aged 8 to 17 years (13 questions) iii) Adults over 18 (14 questions) After receiving an information note, eligible patients or their parents will complete the questionnaires. A total of 200 patients will be recruited for each questionnaire. A statistical evaluation will be carried out using 200 questionnaires for each targeted population in order to validate the psychometric properties of the questionnaire as well as investigate the degree of correlation between the scores of the mini-questionnaire and those obtained using the Europrevall reference questionnaire.
The purpose of this study is testing the use of Enhanced-Butanol purified-Food Allergy Herbal Formula-2 (E-B-FAHF-2) Chinese herbal therapy in combination with multi-food oral immunotherapy (OIT) and Xolair® (Omalizumab) to help children and adults who are allergic to foods be able to safely tolerate food allergens. Specifically in this protocol, the food allergens are milk, egg, peanut, almond, cashew, hazelnut, walnut, sesame, and/or wheat. Omalizumab is considered an investigational drug for the treatment of food allergies in children and adults. Investigational means it has not been approved by the Food and Drug Administration (FDA) for use in the U.S. The researchers hope to learn whether the addition of Chinese herbal therapy (E-B-FAHF-2) can improve the outcome of sustained unresponsiveness (which is the ability to consume a food allergen and pass an oral food challenge after being off treatment for 3 months) as compared to placebo (i.e. subjects with OIT/Omalizumab + herbal vs. OIT/Omalizumab + placebo), and will help adults and children be able to safely ingest the foods they are allergic to.
