title: [Acarex test and acarosan effect in house dust mite allergy in 2 year follow-up].
abstract: Clinical investigations of the effect of the acaricide product Acarosan shows in a large collective of patients beneficial results, whereby the patients are examined up to three months after sanitation. The remaining patients of this study are followed up one and two years after sanitation in open clinical trials. Without exception Acarex test values decrease highly significant after three months, indicating the effective elimination of the house dust mites by Acarosan treatment and consequently the reduction of the allergen containing excreta. The values increase after one year, but after a repetition of the Acarosan treatment they decrease again to the level reached after the first sanitation. The best results are achieved by sanitation of carpets, less favourable results are obtained by treating matresses and upholstered furniture. After sanitation all patients with monovalent house dust mite sensitization report an improvement of their symptoms (eyes, nose, bronchi) up to two years. Drug consumption is variable and decreases over all for up to two years. Peak flow meter values improve in the first year and even further more in the second year. The clinical improvement does not depend on sex, living area or former immunotherapy. During the two year observation period immunologic parameters do not change. 25.6% of the patients show a negative provocation test after the first year and 57% after the second year. Side effects due to the sanitation or signs of sensitization against Acarosan are not observed.
