Abstract:
Objective To investigate the therapeutic effects and safety of beraprost sodium on vascular endothelial dysfunction in elderly patients with lower extremity arteriosclerotic occlusive disease (LEAOD).Methods A total of 80 patients with LEAOD were randomly divided into 2 groups:the treatment group and the control group (n=40 each group).All patients were treated with conventional antihypertensive,antidiabetic,hypolipidemic,antiplatelet drug therapy and non-drug therapy such as smoking cessation,foot care.In addition,patients in the treatment group received 40 μg oral beraprost sodium at a dose of 120 μg/day,3 times/day for 30 days.The changes in symptoms,vital signs,the function of liver and kidney,hemorheology,and serum nitric oxide (NO)were observed before and after the treatment.Results No adverse reactions happened among all patients.After 30 days treatment,there was a significant difference in the total efficacy between the treatment and control groups (80％ vs.35％,x2 =19.60,P＜0.01).The levels of plasma viscosity,erythrocyte aggregation index and serum NO in the control group were (1.70±0.19) mpas.s,5.69±1.08,(43.86±5.20) μmol/L,respectively before the treatment and (1.36±0.14) mpas.s,3.23±0.67,(56.84 ± 7.05) μmol/L,respectively after the treatment.The levels of plasma viscosity,erythrocyte aggregation index and serum NO in the treatment group were (1.71 ±0.18) mpas.s,5.70±1.04,(44.24±5.40) μmol/L,respectively before the treatment and (1.10±0.12) mpas.s,2.80 ±0.52,(64.00±8.15) μmol/L,respectively after the treatment.Compared with pretreatment,the levels of plasma viscosity and erythrocyte aggregation index in the two groups were significantly decreased and serum NO level was increased after the treatment (t=9.07,12.17,17.85,15.76,9.38,12.78,respectively,all P＜0.05).Compared with the control group,the levels of plasma viscosity and erythrocyte aggregation index in the treatment group were significantly decreased and serum NO level was increased (t =8.91,3.27,4.21,all P＜0.05).Conclusions The oral beraprost sodium can effectively and safely improve the hemorheologic and endothelial function in elderly patients with LEAOD.
