Filter by:The Nutrition Study of the GA2LEN Follow-Survey was designed to investigate the association between usual dietary intake and allergic and respiratory outcomes in adults across Europe. Within this framework, a food frequency questionnaire (FFQ) was designed to ascertain usual dietary intake of 250 food items, which was translated into the languages of the participant centres. Information on daily intake of foods, nutrients, and flavonoids was derived.
The purpose of this study is to evaluate the clinical usefulness of assessing specific human allergy antibodies and other immunologic parameters associated with the diagnosis, evolution, and management of allergic disease.
Few studies have been conducted to optimize safety of multiple food allergen oral immunotherapy (OIT) in conjunction with Omalizumab as well as to identify the immunological mechanism(s) underlying any long-lasting effects of OIT. To address these issues in the field of food allergy research, we have designed this study to test whether: 1) Omalizumab improves the safety of multiple food allergen OIT in subjects with multi food allergies, 2) Omalizumab treatment with multiple food allergen OIT is associated with the ability to use a lower maintenance dose of each food allergens in the OIT regimen, particularly in younger subjects with food allergies.
This is a phase II open label study on the use of Ibrutinib on the inhibition of food-induced anaphylaxis in adults with food allergy. Ibrutinib (brand name Imbruvica) is currently FDA approved for the treatment of mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and Waldenstrom's macroglobulineia (WM). We propose to administer this approved drug to adults with food allergy to inhibit food allergy responses.
The proposed study intends to compare the outcome of food challenge in hazelnut allergic patients with the outcome of basophile activation tests using hazelnut extract and components.
The purpose of this patient registry is to demonstrate safety and efficacy of food oral immunotherapy in food allergic patients. Factors that lead to adverse reactions will be identified. The frequency of rescue epinephrine use will be recorded.
The study will ascertain the ability of preschool lung function tests to distinguish healthy children from those with wheeze, and to differentiate phenotypes of wheezy children (high and low risk for asthma as defined by API) in order to predict response to therapy, and to explore the correlation between preschool lung function test results and symptoms, in order to develop objective methods for monitoring asthma.
This is a pilot randomized, double-blind, placebo controlled study which will be conducted at a single center. All participants will receive oral immunotherapy for their specific food allergies (limited to 5 of those food allergens in IND 14831). In a 3:1 ratio, 36* participants will receive Xolair for 16 weeks while 12* will receive corresponding placebo instead of Xolair. 12 controls will be enrolled who will receive no OIT and no Xolair. These 12 controls are not part of the randomization. The total number of participants randomized to the two arms is 48*.
In Italy, few data about anaphylaxis due to peanuts in pediatric age are available, conversely data about walnuts/hazelnuts, shellfish/mollusks anaphylaxis have not yet been collected. Children with physician-confirmed food allergy to peanuts, walnuts/hazelnuts and shellfish/mollusks will be recruited from 9 allergy clinics located in the Italian Territory (Bologna, Lecce, Napoli, Palermo, Parma, Pavia, Roma, Torino, Trento). Parent of food allergic children will compile a food allergy questionnaire (questions about general information on the family, on life and food habits, on indoor environment, on health status, on clinical aspects of the allergy, on the access to diagnostic and treatment resources). Parent of healthy children will compile a control questionnaire (questions about general information on the family, on life and food habits and on indoor environment) The 1-year survey will determine the frequency of anaphylaxis in allergic outpatient children.
This is a phase 2 randomized, double-blind, placebo controlled study which will be conducted at multiple centers in the U.S. All subjects will receive oral immunotherapy for their specific food allergies (limited to 5 of those food allergens in Investigational New Drug (IND) 14831). All subjects will receive Omalizumab for 16 weeks. The subject's allergens will be introduced in a rush desensitization day at week 8. Subjects will return to clinic to escalate the dose of their allergens until 2,000mg protein of each allergen is reached Subjects will return to clinic for a DBPCFC to each allergen at week 30. If subjects are nonreactive to 2 or more allergens during their DBPCFC at week 30 they will be randomized to one of three double blinded arms: Arm A- continue with current dose (2000 mg each food allergen protein), Arm B-300 mg of each food allergen protein, Arm C-placebo (avoiding food allergen protein), their current dose. All subjects will return to clinic for a DBPCFC to each allergen at week 36. The final challenge of week 36 will be the final end of study visit. Safety is a paramount concern in the study design and will be monitored carefully throughout the study. Study subjects and their parents/guardians will receive extensive education on food allergy reactions and medication use.
