[Clinical study of bronchial asthma in adult, intractable asthmatics after introduction of guideline therapy].
Introduction of Guideline for asthma treatment proposed by the committee of Japanese allergology have a tremendous impact on patients with bronchial asthma. Intractable asthmatics who have had to take some oral steroid to overcome disease severity, may have also some merit by this treatment, so that some of them might be no longer considered as intractable asthmatics. To clarify this, multicenter study was conducted. In this study, a case who have had more than 5 mg of prednisolone and/or 800 mu g of beclomethasone dipropionate throughout the year, was diagnosed as intractable asthmatics. In 845 case, 14.7%, 123 cases were diagnosed as intractable. These cases were significantly to be non-atopic and adult onset. Also, they have a significant tendency to be deteriorated by infection and careless drug administrations. Using the multiquantification method to examine the most powerful factor on intractable asthmatics, type of asthmatics was the most important and the past history of severe attack was the second. When intractable asthmatics diagnosed mainly by their BDP usage (BDP-intractable) were compared with intractable diagnosed by oral PSL (PSL-intractables), BDP-intractables were significantly atopic compared to PSL-intractables.
