Therapeutic Use of Intravenous Vitamin C in Allogeneic Stem Cell Transplant Recipients

Vitamin C is a nutritional supplement that can help fight inflammation. Most patients who
have a stem cell transplant have lower than normal levels of vitamin C in their blood.
Patients will receive intravenous Vitamin C the day after transplant for two weeks, followed
by oral vitamin C until six months after transplant. The effect of the Vitamin C on
non-relapse mortality (NRM), time to engraftment, rate of acute graft-versus-host disease and
to characterize the safety and tolerability of the vitamin C regimen.
