Allergen specific immunotherapy in nasobronchial allergy.
BACKGROUND
More than one antigen has been used for immunotherapy of allergic disorders. So far less than five antigens have been employed with variable results.


OBJECTIVE
To evaluate effect of multiple antigens up to six in the immunotherapy of nasobronchial allergy.


METHODS
Based on clinical history, symptoms present for at least 3 years with set criteria of immunomodulation for asthma and rhinitis: documented IgE mediated asthma and rhinitis, failure in allergen avoidance and moderate to severe clinical manifestations.


METHODS
Five hundred cases of various allergic disorders attending allergy clinic of Bombay hospital were screened. Allergen specific immunotherapy was initiated in 131 subjects (56 -rhinitis and 75 asthma) with prior consent. Patients suffering from allergic disorders secondary to diseases or drug therapy were excluded. Multiple allergen immunotherapy was given at specific intervals up to a period of one year. Allergen extracts were prepared as per standard technique. For statistical analysis "students't test" was used.


CONCLUSIONS
Significant improvement in PEFR, reduction in skin sensitivity to allergens used in immunotherapy formulation and symptomatic relief without any untoward reaction show that multiple allergen immunotherapy is as effective as monoallergen immunotherapy in nasobronchial allergy.
