Objectives: The aim of this study was to evaluate the acute and chronic effects of mesoglycan on the endothelial function and arterial elastic properties in patients with metabolic syndrome (MetS). Background: MetS is defined by a clustering of vascular risk factors that demand both pharmacologic and non-pharmacologic interventions, including body weight reductions and physical activity. The correction of endothelial dysfunction and arterial wall distensibility associated with MetS have lately received increasing interest. Methods: Thirty consecutive ambulatory patients affected by MetS were 2: 1 randomized in a double-blind fashion to receive mesoglycan or placebo, respectively. In the first phase of the study, we evaluated the acute effects of a single i.m. administration of mesoglycan (60 mg) or placebo on vascular reactivity, as assessed by brachial flow-mediated dilation (FMD). Then, patients were chronically treated with mesoglycan per os (50 mg twice a day) or placebo for 90 days. At the end of this period, vascular reactivity and the arterial wall elastic properties were evaluated. Results: In the mesoglycan group, FMD increased above baseline after acute administration, with a maximum increment of 52% after 2 h. FMD was also significantly greater than baseline after 90 days of chronic treatment. In the placebo group, FMD was unaffected by both acute and chronic mesoglycan administration. Moreover, after 90 days of mesoglycan treatment, a marked improvement in arterial distensibility and compliance was detected and arterial stiffness reduced significantly. Conclusions: This small, preliminary study shows that mesoglycan exerts relevant effects on vascular physiology, both in an acute setting as well as after prolonged, three-month treatment, in patients affected by metabolic syndrome.
