[Specific desensitization of pollinosis by various allergen extracts (author's transl)].

During an observation period of 3 years questionnaires as well as examination results of 155 patients suffering from pollen allergy were evaluated with the aim to determine the efficiency and side effects of aqueous (SEVAC, Prague) and depot (SSW, Dresden) allergen extracts used in the GDR for desensitization. It was found that the rate of success increased with desensitization treatment continued over several years independent of the allergen extract used. When aqueous allergen extracts are administered the therapeutic success of the preseasonal as well as the perennial desensitization was shown to be significantly greater. We found fewer side effects using depot extracts.
