What this trial studies

This observational study aims to assess the long-term effects of allergen immunotherapy in children aged 5 to 18 years who are treated at Hans Christian Andersen Children's Hospital. Participants will undergo either subcutaneous or sublingual immunotherapy for allergies related to grass pollen, birch, house dust mites, or venom. Data will be collected from patient records, including symptoms, medication use, and test results, with follow-up questionnaires administered 5 and 10 years post-treatment to evaluate ongoing allergy symptoms and asthma. The study will systematically monitor treatment effects and adverse events annually during the treatment period.
