Brief Summary

Background: This study investigated whether administering erythropoiesis-stimulating agents (ESAs) improves endothelial function in patients with non-dialysis chronic kidney disease (CKD) and anemia. Methods: This single-center, prospective, single-arm comparison study enrolled patients with non-dialysis CKD (stages 4-5) and hemoglobin levels <10g/dL. ESA administration followed the Kidney Disease: Improving Global Outcomes guideline. The primary endpoint was the change in flow-mediated dilatation after ESA administration in individual patients. The secondary endpoints were changes in 6-minute walk test results, blood pressure, New York Heart Association class, and echocardiographic parameters. The echocardiographic parameters examined included chamber quantification, Doppler parameters, and systolic and diastolic function parameters. Results: Initially, 13 patients were screened, but 2 discontinued due to either heart failure or voluntary withdrawal. The mean flowmediated dilatation values significantly increased by 10.59% (from 1.36%±1.91% to 11.95%±8.11%, P=.001). Echocardiographic findings showed that the left ventricular mass index decreased by 11.9g/m2 (from 105.8±16.3 to 93.9±19.5g/m2, P=.006), and the left atrial volume index decreased by 10.8mL/m2 (from 50.1±11.3 to 39.3±11.3mL/m2, P=.004) after 12weeks of ESA administration. There were no significant differences between pre- and post-ESA treatment 6-minute walk test results. No significant side effects were observed during the study period. Conclusions: This is the first clinical study to demonstrate that an ESA improves endothelial dysfunction, left ventricular hypertrophy, and left atrial volume in patients with non-dialysis CKD. Thus, ESAs may be considered as adjunctive therapy for reducing cardiovascular risk in these patients.
