Summary

This study is to assess whether a single oral loading dose of 100,000 IU vitamin D3 prior to allogeneic hematopoietic stem cell transplant (aHSCT) can achieve optimal 25 hydroxy-vitamin D3(25-OH-D3) levels (\>75nmol/L) at one month post aHSCT, and maintain adequate levels for at least three months, compared to our standard practice of 2000 IU vitamin D3 daily. 25-OH-D3 levels will be measured prior to vitamin D3 supplementation, and 30 as well as 100 days post vitamin D supplementation. We hypothesize that the intervention will prevent vitamin D insufficiency or deficiency in aHSCT recipients, therefore benefit aHSCT-associated morbidity, including osteoporosis.
