[The pathogenesis of acne vulgaris (author's transl)]

Abstract

Stickl's method of oral treatment of acne vulgaris with antigens has been carried out on 26 test persons. During the treatment the number of comedones increased significantly and the number of papules decreased significantly. Biochemically, a significant increase of the free fatty acids and a significant decrease of the triglycerides could be demonstrated in the skin surface lipids, the total amount remaining unchanged. The following important conclusions for the pathogenesis of acne may be drawn: 1. The living conditions for Corynebacterium acnes on the surface of the skin or in the ducts of sebaceous glands respectively are influenced by the immunological system of the host. 2. The free fatty acids have a comedogenic effect in vivo. 3. The free fatty acids are not responsible for the development of inflammatory acne efflorescences.
