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.

Who should consider this trial

Good fit: Ideal candidates are children aged 5 to 18 years who are receiving allergen immunotherapy at the participating hospital.

Not a fit: Patients who have received less than 12 months of allergen immunotherapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness of allergen immunotherapy, potentially improving treatment strategies for children with allergies.

How similar studies have performed: While similar studies have explored the effects of allergen immunotherapy, this specific long-term observational approach in children is relatively novel.
