Rational for statin use in psoriatic patients

Psoriasis represents a common skin diseasewhich is clinically manifested by chronic cutaneous lesions. It has been observed that psoriasis is associated with an increased risk of cardiovascular diseases, which is contributed to the inappropriate lipid metabolism. Statins are commonly used in clinical practice to lower cholesterol concentration and, accordingly, decrease the individual risk of developing a cardiovascular episode. There have been reports that statin administration could also result in better management of psoriasis. The observed beneficial effects are contributed to the effects on lipid metabolism, including that in skin, as well as anti-inflammatory and immunomodulatory properties of statins. Simvastatin and atorvastatin were found to improve the clinical outcome in patients with psoriatic skin lesions. Clinically, the effectiveness of this novel treatment was confirmed by the significant reduction in PASI score. To date several cases have been reported in which atorvastatin or pravastatin worsened psoriasis. Based on these results, it seems that statins represent a promising class of medications which could be extensively used in psoriasis.
