Below we will list the departments and units that form part of Vall d’Hebron Hospital and the main diseases that we treat. We will also make recommendations based on advice backed up by scientific evidence that has been shown to be effective in guaranteeing well-being and quality of life.
We will guide you from your first visit to the centre, allowing you to find all the departments and make the most of our facilities. Whatever the reason for your visit, we will explain how to get about the hospital.
Immunotherapy is a long-term, preventive treatment that aims to reduce the symptoms of patients diagnosed with hay fever, allergic asthma, conjunctivitis, or allergies to insect stings.
The objective of immunotherapy with allergens is to change the allergic response by inducing immunological tolerance. A patient with allergies has symptoms when they are exposed to the relevant allergen. Immunotherapy uses a larger quantity of the allergen, in combination with a different route of entry into the body. This modifies the immune system's abnormal response, causing it to develop a tolerance to the allergen instead of inflammation and allergic symptoms.
Immunotherapy was originally administered by subcutaneous injection.There are currently liquids or fast-dissolving tablets that can be used in sublingual immunotherapy for certain allergens.
Subcutaneously injected treatments are administered every 4 or 8 weeks; sublingual treatments must be administered daily. This is generally continued over a period of 3 to 5 years. Many patients experience a prolonged protective effect after that period, so an assessment may be made of stopping the immunotherapy.
Immunotherapy is indicated for patients with allergic rhinoconjunctivitis or allergic asthma who:
Immunotherapy with hymenoptera venom is indicated for individuals who experience a severe generalised reaction to bee or wasp stings.
Immunotherapy is generally safe and well tolerated when used in suitably selected patients. Even so, localised and generalised reactions can occur.
The most frequent reactions are localised ones, such as redness or itching at the injection site. These reactions are most likely to occur during the first administration of the treatment, which is why immunotherapy starts at the Allergology Department and, if well tolerated, can be continued on an outpatient basis.
