Patient's question:
9-year-old child, allergic rhinitis for 8 years.Doctor's answer:
Immunotherapy, also known as specific desensitization therapy, involves the subcutaneous injection of allergen extracts with positive skin test results, starting with a low concentration and small dose, gradually increasing the concentration and dosage over several months, and then switching to a maintenance dose. Patients treated with this method can develop specific IgG blocking antibodies, which block the binding of allergens to IgE and reduce the sensitivity of mediators to the allergen.
