INTRODUCTION: Arteriosclerosis obliterans (ASO) causes ischemic symptoms of the lower limbs, reducing quality of life (QOL), and has a poor prognosis. Early diagnosis and treatment are necessary. In this study, the effects of long-term administration of beraprost sodium (beraprost) to treat ASO were investigated.
METHODS: One hundred and eighty eight patients treated with beraprost for ≥1 year were retrospectively identified. Outcomes were lower limb ischemic symptoms, carotid intima/media thickness (IMT), and cardiovascular events. Patients reported visual analog scale scores for major symptoms at baseline and after 3, 6, and 12 months of treatment.
RESULTS: Overall, 188 patients (mean age 70.8 ± 10.15 years, Fontaine classification: grade I 14.4%, grade II 85.6%) treated with beraprost for 2.4-10.7 years (mean 6.5 years) were included in this study. Administration of beraprost significantly reduced patient-reported severity of lower limb ischemic symptoms in all patients at 12 months, including those with diabetes, hypertension, or dyslipidemia. IMT decreased from 1.09 ± 0.09 mm at baseline to 1.04 ± 0.11 mm at 12 months (P < 0.001). Decreases in IMT were similar in patients with diabetes, hypertension, or dyslipidemia. Overall, 26 (13.8%) events occurred during a mean follow-up of 6.5 years, including 23 cardiovascular events (unstable angina in three patients, myocardial infarction in six patients, cerebral infarction in eight patients, and transient cerebral ischemic attack in six patients) and non-cardiovascular death in three patients. Beraprost at 120 μg/day significantly reduced the risk of ischemic symptoms compared with <120 μg/day (adjusted hazard ratio: 0.17; 95% confidence interval: 0.06, 0.45; P < 0.001). No severe adverse events or adverse events requiring dose reductions/discontinuation occurred during long-term administration of beraprost.
CONCLUSION: Beraprost reduced lower limb ischemic symptoms, IMT, and the incidence of cardiovascular events in patients with ASO.
