Summary

Serum copper level and oxidase activity of ceruloplasmin were determined in psoriasis patients before and after active helio- and thalassotherapy. In a group of 30 patients of both sexes with psoriasis the serum copper level was 29,2% higher in comparison with 20 normal controls and oxidase activity of ceruloplasmin was 116.8% higher than in 100 normal controls. After 4 weeks-long thalassotherapy with 3–4 h insolation daily, in correlation with clinical improvement and complete disappearance of the psoriatic lesions, the serum copper level decreased by 28.3% in a statistically significant manner. The oxidase activity of ceruloplasmin decreased insignificantly. The pathogenesis of the psoriasis and the process of keratogenesis and melanogenesis in connection with the copper pathochemistry and the UV-irradiation are discussed.

Zusammenfassung

Es wurde bei Kranken mit Psoriasis das Kupfer und die Oxidaseaktivität des Ceruloplasmins in Serum vor und nach aktiver Helio- und Thalassotherapie untersucht. In einer Gruppe von 30 Kranken mit Psoriasis beider Geschlechter war das Kupfer und das Ceruloplasmin vor der Behandlung um 29.2% höher als bei einer Kontrollgruppe von 20 gesunden Probanden. Die Oxidaseaktivität des Ceruloplasmins war um 116,8% höher als bei einer Kontrollgruppe von 100 gesunden Probanden. Nach 4wöchentlicher Helio- und Thalassotherapie, bei 3–4 Std tägliche Insolation war, paralell zur klinischen Besserung und dem Verschwinden der Hautläsionen eine statistisch signifikante Herabsetzung des Kupfers um 28,3% aufgetreten. Die Oxidaseaktivität des Ceruloplasmins zeigte dagegen keine statistisch signifikante Herabsetzung. Es wird die Pathogenese der Psoriasis und der Prozeß der Kerato- und Melanogenese im Zusammenhang mit der Pathochemie des Kupferstoffwechsels und der UV-Strahlung besprochen.
