[Psoriasis, a systemic disease?].
It has long been recognized the epidemiological association of psoriasis, especially the most severe forms, with several diseases that share a common pathogenic substrate involving TNF-alpha and different target organs (arthritis and Crohn's disease, for example), as well as an increased risk of coronary heart disease and occlusive cardiovascular disease. In the patient with severe psoriasis there is also an increased prevalence of obesity, dyslipemia, adult diabetes mellitus, alcohol abuse and tobacco habit which contribute to the increased risk of mortality associated with atherosclerosis. Recently it has been identified the so-called metabolic syndrome, characterized by the association of abdominal obesity, atherogenic dyslipemia, hypertension, insulin resistance with or without glucose intolerance and a proinflammatory and prothrombotic state as a risk factor for cardiovascular disease. There is evidence that in rheumatoid arthritis as well as in psoriasis, chronic inflammation has a pathogenic role in the metabolic syndrome and associated comorbidities, and its adequate treatment may contribute to revert it. The dermatologist should recognize the elements of the metabolic syndrome and propose the patient with psoriasis, in addition to the optimal dermatologic treatment, changes in life habits and appropriate drug therapy to reduce the risk of cardiovascular morbi-mortality.
