NCT03534674

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • To assess the efficacy of 100,000 IU vitamin D3 prior to aHSCT

    To assess the efficacy (the proportion of patients achieving sufficient serum 25-OH-D3 level) after a single oral loading dose of 100,000 IU vitamin D3 prior to aHSCT, with subsequent vitamin D3 2000 IU daily, in preventing vitamin D insufficiency/deficiency in the first 100 days post-aHSCT.

Study Arms (2)

Intervention

EXPERIMENTAL

Participants assigned to the intervention group will receive a single oral loading dose of 100,000 IU vitamin D3 on the day of hospital admission for aHSCT, with subsequent vitamin D3 2000 IU daily.

Dietary Supplement: vitamin D3

Control

NO INTERVENTION

Participants assigned to the control group will be advised to take our current vitamin D regimen (2000 IU vitamin D3 daily).
