The advances of hyposensibilisation therapy in bronchial asthma patients allergic to house dust antigen.

The hyposensibilisation therapy was realized in a population of 72 adult asthma patients allergic to house dust, feathers and molds. In this number 52 patients were treated by aqueous extracts of allergens produced by Pasteur Institute in Paris (20 patients by house dust extract only) and 20 patients by D. pteronyssinus tyrosine adsorbate (Migen Bencard). The very good and good results of hyposensibilisation were observed in 67.3% of cases receiving the aqueous extracts of allergens and in 80% of cases treated by Migen. Side effects of such form of therapy were not observed. The extract of house dust mite emulsified in tyrosine is, in the authors opinion, expecially successful in the treatment of atopic asthma patients sensibilized to inhalant allergens.
