详细描述
Immunotherapy is a specific treatment for allergic diseases. Unlike conventional pharmacological treatment, immunotherapy is the only treatment that could modify the natural course of allergic disease. This is a prospective double-blind placebo controlled study with three arms of treatment: placebo and two active (one of the active arms will receive subcutaneous immunotherapy and the other one will receive sublingual immunotherapy).
