Short-Term Effects of Beraprost Sodium on the Markers for Cardiovascular Risk Prediction in Type 2 Diabetic Patients with Microalbuminuria

초록

Background: To evaluate the changes in cardiovascular risk markers including pulse wave velocity (PWV), microalbuminuria, inflammatory cytokines, and adhesion molecules after treatment with beraprost sodium (BPS) in patients with diabetic nephropathy Methods: This was a multicenter, prospective, randomized, double-blind, placebo-controlled trial. Type 2 diabetes mellitus patients with microalbuminuria were included. The primary endpoints were changes in microalbuminuria in spot urine and PWV after BPS or placebo (PCB) treatment for 24 weeks. The secondary endpoints were changes in clinical and metabolic parameters. Results: A total of 52 patients completed the 24-week trial. Changes in PWV were not different significantly in the BPS and PCB groups (right, P=0.16; left, P=0.11). Changes in microalbuminuria were 14.2 +/- 157.0 and 34.5 +/- 146.6 (mu g/mg Cr) in the BPS and PCB groups, respectively (P=0.63). Subgroup analysis in the high blood pressure (BP) group (baseline systolic BP >120 mm Hg and diastolic BP >80 mm Hg), showed that microalbuminuria decreased by -47.6 in the BPS group compared with an increase by 116.4 (pg/mg Cr) in the PCB group (P=0.04). Also, in the large waist circumference group (>95 cm), microalbuminuria decreased significantly in the BPS group (P=0.04). Conclusion: Short-term treatment of BPS for patients with diabetic nephropathy did not show significant improvement in various cardiovascular risk factors. However, BPS significantly decreased microalbuminuria in study subjects with higher cardiovascular risk such as high BP or large waist circumference.
