A Long Term, Observational Follow-Up Study of Children and Young People Who Underwent an 18-Month Course of Oral Immunotherapy Treatment for Peanut, Egg or Milk Allergy (5-15 Years Post-Treatment)

The goal of this observational study is to learn about the long-term outcomes of children and young people who underwent an 18-month course of oral immunotherapy (OIT) treatment for peanut, egg or milk allergy. It aims to: • Compare long-term changes in health-related quality of life (HRQL) at 5-15 years after stopping OIT in participants who achieved remission and those who did not. Participants will attend a single follow-up visit for: * A blood test * Skin prick test (SPT) * Allergy questionnaires

Study to Evaluate the Safety, Pharmacokinetic, and Pharmacodynamic Effects of MY006 in Healthy Volunteers and Patients With Peanut Allergy

The goal of this clinical trial is to evaluate the safety, pharmacokinetics, and effectiveness of MY006, a therapy designed to prevent severe or potentially life-threatening allergic reactions caused by accidental peanut intake. In the first part of the study, adult participants receive one dose or two doses of MY006 or a placebo, administered by subcutaneous injection. The safety of MY006, including the number of adverse events, injection-site reactions, and immunogenicity, in these participants will be reviewed by an independent Safety Monitoring Committee and, if the safety is judged acceptable, the second part of the study will be started. In the second part of the study, adult and adolescent participants with peanut allergy receive one dose of MY006 or a placebo, administered by subcutaneous injection. Several weeks later, the participants are given a food peanut challenge to assess reactions and treatment effects. The duration of the study for participants is for up to 32 weeks.

The Role of Filaggrin Mutations and Sensitization Pathways in Allergic Rhinitis and Peanut Allergy

Caucasian male and female participants age 18 years of age and older will be enrolled in this study if they have known birch or peanut allergies or known to be non-atopic. Participants will undergo skin testing to confirm their allergies if not completed in the last 12 months. Medications and medical history will be captured with a focus on atopic disorders. Participants will undergo birch and peanut patch testing to assess penetration and if potential correlation exists with filaggrin genotyping and phenotyping. Blood samples will be drawn from participants and DNA isolated for genotyping of null mutations in filaggrin.

Blood Samples for the Study of Peanut, Tree Nut and Other Food Allergies

Food allergies are now a major problem. These experiments involve getting blood from people with food allergies and from people without food allergies. The blood collected will be used to answer questions and find information about peanut and other food allergies. Samples will come from: * People signed up by the investigators at the University of Colorado Denver * University of North Carolina, Massachusetts General Hospital, Children's Hospital of Colorado and the Immune Tolerance Network (Benaroya Research Institute) where people have been treated for peanut allergies * University of North Carolina, Massachusetts General Hospital, National Jewish Health and The Children's Hospital in Denver where people have taken part or will take part in clinically indicated oral food challenges. Blood and health histories from the University of North Carolina, Massachusetts General Hospital, National Jewish Health, The Children's Hospital and the Immune Tolerance Network will not have personal information linked. The specific aims of this experiment are: 1. Come up with a lab test that will predict how bad an allergic reaction will be to peanuts. 2. Find out what part of a peanut causes allergic reactions. 3. Come up with preventions that can block peanut allergies. 4. Find the strongest proteins in walnuts.
