[Co-morbidities in psoriasis vulgaris].

Epidemiologic data document not only a higher prevalence of joint involvement among psoriasis patients than previously thought, but also an association with numerous other diseases, including depression, smoking, alcoholism, Crohn's disease, and metabolic syndrome. The resulting increased cardiovascular mortality is of particular clinical importance, and its pathogenetic link as a complication of the psoriatic inflammation is well recognized. Thus, we need to re-invent the management of psoriasis: Dermatologists are not only the sentinel regarding the early diagnosis of psoriatic arthritis, but also of metabolic complications such as dyslipidemia or diabetes. Moreover, they need to keep in mind interactions between (systemic) anti-psoriatic drugs and the co-medication of their patients as well as possible consequences of these co-medications on the course of psoriasis. To successfully accomplish this mission, a comprehensive management concept and ground-breaking research are urgently needed.
