ICENSE study

Not Applicable

• Conditions: Diabetic nephropathy; Diabetic nephropathy, proteinuria

• Registration Number: JPRN-jRCTs042180076
• Lead Sponsor: Wada Takashi

Brief Summary

DL apheresis was performed on 40 patients with diabetic nephropathy enrolled in this study. it was suggested that LDL apheresis for diabetic nephropathy presenting severe proteinuria with refractory hypercholesterolemia is useful for improving survival.
