Park, Soh, Park, and Jeong: Effects of Beraprost Sodium Evaluated by Digital Infrared Thermal Imaging in Diabetic Patients with Peripheral Arterial Disease

Abstract

Purpose

This study examined the effects of beraprost sodium on digital infrared thermal images in patients with peripheral arterial disease caused by type 2 diabetes mellitus.

Materials and Methods

Twenty-five diabetic patients with peripheral arterial disease were treated with beraprost sodium in a prospective, multicenter, cohort study from February 2013 to December 2014. Beraprost sodium (40 µg) was administered orally 3 times daily (120 µg/day) for 6 months. The visual analogue scale (VAS) and digital infrared thermal imaging (DITI) were performed to compare the blood flow improvement between before and after dosing.

Results

Among the 25 patients included in the evaluation, 22 patients completed the study. A significant increase in body temperature was observed in the front and left side, particularly in the plantar side in DITI compared to that before and after administration. An increase in body temperature was observed at the frontal part from 28.1°C±2.3°C to 29.1°C±2.1°C (p=0.021), at the left side from 27.8°C±2.4°C to 28.6°C±1.9°C (p=0.028), at the plantar part at 24.0°C±1.5°C, and at the plantar part at 27.1°C±2.4°C (p<0.01). The VAS decreased significantly from 5.4±1.3 to 2.7±2.0 after 6 months of treatment (p<0.01).

Conclusion

Beraprost sodium is a safe and easy-to use oral medication for diabetes peripheral arterial disease. It can be expected to increase the blood flow and decrease the lower extremity pain statistically after being taken for 6 months.
