Vitamin D deficiency remains common among pediatric patients undergoing hematopoietic stem cell transplant (HSCT) despite both aggressive and standard of care strategies. This study examined the safety and efficacy of single high-dose oral vitamin D therapy (Stoss therapy) for treatment of vitamin D deficiency in HSCT recipients. Patients ages 1-21 years presenting for HSCT were randomized to receive either Stoss regimen plus weekly/daily supplementation or standard of care, per US Endocrine Society guidelines. Among the total 48 subjects, 22 (46%) were randomized to Stoss and 26 (54%) to control arms. Baseline 25-hydroxyvitamin D (25-OHD) levels were insufficient/deficient in total of 34 (71%) patients, without difference between treatment groups. The Stoss regimen was well tolerated and no toxicity was observed. At Day +30, mean 25-OHD levels were significantly higher (P = 0.04) with Stoss (42.3 ± 12 μg/l) compared to controls (35.6 ± 14.3 μg/l), and a higher proportion of Stoss patients had adequate vitamin D levels than controls (85% vs 65%). Stoss therapy is a safe and efficacious treatment option for vitamin D deficiency in children undergoing HSCT and may achieve sufficient levels more rapidly than standard of care.
This trial was registered at www.clinicaltrials.gov as NCT03176849.

Better than Daily has the following

32 items in BETTER THAN DAILY category

Non-daily (Bolus) is better:

1. Better compliance for everyone
   • Fewer opportunities to forget.
   • If happen to forget, just take the dose many days later
   • Fewer times to have to take a pill - for those who dislike doing so
2. Non-daily gets more vitamin D to the cells for the ~20% who have a poor Vitamin D Receptor
   • A high concentration gradient is one of 14+ ways to get past Vitamin D Receptor limitations
   • So, while 80% get no extra benefit from non-daily dosing, 20% will get an extra benefit
