Serial Phlebotomy in Voluntary Blood Donors

Status Completed

Clinical Trial Summary

Blood donation has been proposed to be associated with reduced risk of cardiovascular disease, but the effects of phlebotomy on vascular function in human subjects have not been well characterized. A prospective randomized double-blind study was undertaken to determine the effects of iron loss and red blood cell loss induced by serial phlebotomy on vascular endothelial function in the brachial artery.

Clinical Trial Description

84 Fe-replete, non-anemic subjects were randomly assigned to one of three experimental serial phlebotomy procedures designed to induce Fe loss or RBC loss. Brachial artery reactivity (BAR, %) in response to transient oxidative stress induced by oral methionine was measured with high-resolution duplex ultrasound imaging before and after study phlebotomy procedures. ;

Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention
