Thiozolidinediones in the Treatment of Patients With Extensive Psoriasis and Concomitant Alimentary Obesity

Abstract

Psoriasis is one of the most common chronic recurrent systemic autoimmune multifactorial diseases, affected the skin, joints, internal organs and systems of the body. Despite the significant prevalence of psoriasis and a large number of studies devoted this problem there is still no single view on the pathogenesis of this dermatosis. To clear up the pathogenesis of psoriasis, it seems to be reasonable to focus on the common comorbidities or multimorbidities, which may occur in the course of psoriasis, as this issue is still insufficiently studied. Recent reports have proven the evidences of indisputable link between psoriasis and obesity. The scientific literature extensively covers the issues of identical pathogenetic mechanisms of inflammatory processes in psoriasis and obesity. Given the current data on the role of systemic inflammation underlying the development of both psoriasis and obesity, the study of molecular mechanisms of its development and in particularly the role of proinflammatory nuclear transcription factors, thiazolidinediones have been found out as pathogenetically justified medicine of choice for the therapy of these diseases. In this study, we determined the effectiveness of using 30 mg of pioglitazone daily for 6 months in the course of treatment for patients with extensive psoriasis vulgaris of moderate severity, who were also diagnosed as having concomitant grade І-ІІ alimentary obesity that was supported by clinical and immunological findings evidenced of systemic inflammation. Analyzing the results obtained, we have found out the prolonged therapy with pioglitazone leads to a decrease in systemic inflammation and contributes to a milder recurrent course of psoriasis.
