    Description / Table of Contents: Zusammenfassung Erythrocyten von 8 Psoriatikern und 8 Kontrollpersonen wurden in vitro mit3H-markiertem freiem DHEA, DHEA-sulfat und DHEA-sulfatid inkubiert. Es zeigte sich, daß die Penetration von DHEA und DHEA-sulfatid durch die Erythrocytenmembran bei Psoriasis um ca. 50% vermindert ist. Im Erythrocyten des Psoriatikers ließ sich, insbesondere nach Inkubation mit DHEA-sulfatid, eine vermehrte Reduktion von DHEA zum ADIOL feststellen. Weiterhin ergab sich eine statistisch erfaßbare Beziehung zwischen dem DHEA-Gehalt im Erythrocyten und seiner Hemmung der G-6-PDH. Die Bedeutung dieser Befunde für den Entstehungsmechanismus des DHEA-Mangels bei der Psoriasis vulgaris wird diskutiert.
    Notes: Summary Erythrocytes of 8 psoriatics and 8 controls were incubated in vitro with3H-labeled free DHEA, DHEA-sulfate and DHEA-sulfatide. It could be demonstrated that in psoriasis the penetration of DHEA and DHEA sulfatide through the membrane of erythrocytes is reduced by approximately 50%. Within the erythrocytes of psoriatic patients an augmented reduction of DHEA to ADIOL was found, especially after incubation with DHEA sulfatide. Furthermore, a statistically defined correlation could be observed between the DHEA content of erythrocytes and the inhibition of red blood cell glucose-6-phosphate dehydrogenase. The significance of these findings for the pathogenesis of a DHEA deficiency in psoriasis is discussed.
