[Immunological therapy in asthma].

The goals of pharmacological treatment of asthma is to achieve clinical control and prevent exacerbations with the minimal adverse effects. Pharmacologic therapies are categorized in two general classes: long-term and quick-relief medications. Local or systemic corticosteroids blockade the late phase reaction of the immunological inflammatory response and reduce airway hyperresponsiveness. This reaction can also be diminished by allergen specific immunotherapy, this treatment also create immunological tolerance for the allergen and prevents new sensitizations. Immunosuppressants and immunomodulators such as methotrexate can be used as part of therapy in patients who does not respond to the recommended treatment, these medications should be used only selected patients under the supervision of an asthma specialist, as their potential beneficial effect may not outweigh the risk of serious side effects. Biomolecular therapy medications, such as etarnecept, are not recommended, more studies are required. The anti-IgE monoclonal antibody, omalizumab, is recommended in adults and children over 12, who have allergy as an important cause of their asthma. In reference to childhood immunizations, there is no evidence of influence on the incidence of asthma, possible beneficial effect on asthma exacerbations with anti-influenzae vaccine. Finally we'll see some interesting points about pharmacogenetics.
