| Popis: | Tetradecylthioacetic acid (TTA) is a bioactive 3-thia fatty acid, giving hypolipidemic response, inhibiting the proliferation and increasing the differentiation of normal adult epidermal keratinocytes and showing anti-oxidant and anti-inflammatory effects. Psoriasis is an inflammatory disease associated with abnormalities in lipid profile, lipid peroxidation, antioxidant capacity, eicosanoid metabolism and increased frequency of cardiovascular events. On this background we have conducted a pilot study to explore the hypothesis that this modified fatty acid could improve dyslipidemia and reduce inflammation in psoriatic patients. In this double-blinded, placebo-controlled study, we assessed the metabolic effects of systemic TTA in a limited number of patients with mild to moderate psoriasis, 1000 mg TTA daily for 28 days. The most important findings were: (i) TTA reduced plasma total cholesterol, non HDL-cholesterol, LDL/HDL cholesterol ratio, triglycerides and total fatty acids; (ii) TTA decreased plasma TNF-α, IL-8 and VCAM-1; and (iii) plasma fatty acid composition changed with an increased level of monounsaturated fatty acids and decreased n-3 polyunsaturated fatty acids. In conclusion TTA exerts both hypolipidemic and anti-inflammatory effects in psoriasis patients. The results further indicate that TTA can be of therapeutic benefit for a subgroup of psoriatic patients. |
