Abstract

Background: Peripheral artery disease (PAD) is a common complication in patients receiving hemodialysis (HD). Cilostazol is used for the treatment of ischemic symptoms in patients with PAD, based on its antiplatelet and vasodilating effects. In addition to these beneficial effects on clinical symptoms in PAD patients, cilostazol has been proposed to have additional effects on clinical symptoms in patients with restless legs syndrome (RLS) via the upregulation of dopamine. We performed an observational, prospective study to evaluate the effect of cilostazol on several clinical and biochemical parameters in HD patients with PAD and RLS. Methods: All the study patients received cilostazol treatment for 12 months. During the study period, several biochemical parameters, such as high-sensitivity CRP, von Willebrand antigen (VW-Ag), triglyceride (TG), high-density lipoprotein (HDL) and malondialdehyde-modified low-density lipoprotein, were monitored. A questionnaire on the physical status of PAD and RLS was also completed. 45 HD patients who received cilostazol were compared with a control group of 22 patients. Results: The patients who continued cilostazol treatment exhibited a improvement in their serum inflammatory and biochemical parameters (VW-Ag, TG, HDL). Although PAD and RLS scores were not improved by multivariate analysis, several patients showed improvement of signs and symptoms which were included in the PAD or RLS scores. Conclusion: The treatment of HD patients with cilostazol improved some of the lipid-related and endovascular inflammatory biochemical parameters associated with PAD, and relieved the clinical symptoms and physical status of PAD in some cases.
