Filter by:This study is researching an experimental drug called linvoseltamab when combined with another drug called dupilumab. The study is focused on patients who have IgE-mediated food allergy. If the patient has an allergy, the immune system overreacts to an allergen (eg, certain foods such as peanuts, milk, shellfish) by producing antibodies called IgE. IgE antibodies are released by cells such as plasma cells. These antibodies and allergen bind to other cells that release chemicals, causing an allergic reaction. The aim of the study is to see how safe and tolerable linvoseltamab is when combined with dupilumab. The study is looking at several other research questions, including: - What side effects may happen from taking the study drugs - Whether linvoseltamab when combined with dupilumab has an effect on other types of antibodies in the blood at different times - How much study drug(s) is in the blood at different times
It is a randomized, sigle-center, controlled trial to evaluate the effectiveness of oral immunotherapy with cashew protein compared with standard treatment (elimination diet) in pediatric patients with cashew allergy.
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 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 to describe the symptoms and their evolution up to the age of 5 years in a population of newly diagnosed infants with a suspected or confirmed allergy to cow proteins, for whom the doctor prescribed the Pepticate® Syneo® replacement formula as soon as they were diagnosed. The Pepticate® Syneo® product is an advanced protein hydrolyzate, food type intended for special medical purposes. This is a product already available on the market.
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.
Testing of a new ready-to-use Tape in comparison to the currently used skin prick test for the diagnosis of allergies. Assessment of clinical equivalence of the SPT Tape for representative common inhalant allergens to conventional SPT in terms of wheal reaction positivity and overall safety. Tests are performed in patients who have a medical history of relevant allergic rhinitis to any of the tested allergens.
A high number of birch pollen-allergic individuals develop hypersensitivity reactions to certain foods, e.g. apples. This food allergy is due to immunological cross-reactivity. Birch pollen-related foods contain proteins, e.g. Mal d 1 in apple, that are structurally related with the major birch pollen allergen, Bet v 1. Hence IgE antibodies and T lymphocytes specific for Bet v 1 recognize these food proteins which results in activation of the immune system and, consequently, in clinical symptoms. In the present study the investigators intend to investigate if and how the consumption of birch pollen-related food allergens affects birch pollen allergy. In other words, the investigators are interested to analyse whether Bet v 1-related food allergens activate Bet v 1-specific memory cells and thus, contribute to the maintenance of the pollen allergy outside the pollen season. Data obtained in this study will help to clarify the immunological and clinical role of cross-reactivity between pollen and food allergies and will reveal whether avoidance of such foods should be recommended for the patients. Finally, novel approaches for diagnosis and therapy of pollen-related food allergens can be developed.
