Psoriasis Clinical Trial
Official title:
Study on the Therapeutic Mechanisms of Dithranol Treatment With Regard to Pro- and Contra-inflammatory Factors, microRNA as Well as Lymph and Blood Vessels in Patients With Chronic Plaque Psoriasis
Dithranol (known in the U.S.A. as anthralin and in Germany as cignolin) is one of the oldest and safest topical anti-psoriatic treatments. However, despite explorative investigations, the skin disease-clearing mechanisms of dithranol remain poorly understood (Painsi et al, JDDG 2015). The purpose of this study is to investigate the therapeutic mechanisms of dithranol in psoriasis.
Skins biopsies from psoriatic skin and blood samples will be taken before (day 0) and at several time points after start (day 4, week 2-3, and week 6-7) of dithranol therapy to be subjected to an explorative analysis (see outcome measures). A total of maximal 15 psoriasis patients will be enrolled. Normal lesion-adjacent skin from 10 patients undergoing surgery for non-inflammatory conditions will serve as control. ;
