Most previous reports suggesting beneficial effects of prostaglandin E1 (PGE1) have been retrospective and uncontrolled. Therefore, this study was undertaken to assess the efficacy of PGE1 in the treatment of ischemic ulcers in patients with peripheral vascular occlusive disease (PVOD). One hundred twenty patients with one to three ischemic ulcers not healing for 3 weeks with standard care were randomized to receive either PGE1 (20 ng/kg/min) or a placebo for 72 hours through a central venous catheter. Ulcers were measured and photographed, and the rest pain was evaluated before and after infusion and at 1- and 2-month follow-up intervals. Fifty-seven patients with 95 ulcers received PGE1. Seventeen ulcers healed (18%); 22 ulcers decreased in size (23%); 37 ulcers remained unchanged or increased in size (39%); five new ulcers developed during the study (5%); and 14 ulcers had inadequate follow-up (15%). Sixty-three patients with 115 ulcers received a placebo. Nineteen ulcers healed (16%); 38 ulcers decreased in size (33%); 45 ulcers remained unchanged or increased in size (39%); three new ulcers developed during the study (3%); and 10 ulcers had inadequate follow-up (9%). None of the above differences between the drug-treated group and the placebo-treated group was statistically significant. This study did not demonstrate efficacy for intravenously administered PGE1 in the healing of ischemic ulcers in patients with PVOD.
