In order to achieve good results with the corticosteroid-therapy in not spontaneously regredient sarcoidoses a longterm treatment (12-24 months) by considerable corticosteroid-doses proves to be necessary; thereby the problem of side-effects by steroids will arise, especially in young women frequently developing a Cushing-syndrome. By our endeavour to prevent this unpleasant phaenomenon we carried through an alternating attempt with two variant kinds of intermittent treatment. The first method relates to 4 successive days in the week (as it is proposed by P. Krakowka) and the second procedure relates to each 2nd day. The second treatment has proved to be the better one. Side-effects appeared in 31. 9 per cent in case of a daily treatment by steroids, in 27.3 per cent after the application of the method of 4 days a week, and in no one case after an application each second day. The results of the treatment by corticosteroids are equal in all the three groups.
