The primary objective of this study is to establish that single dose vitamin A supplementation is feasible and safe in pediatric and young adult bone marrow transplant recipients until day +30 (± 7 days) after hematopoietic stem cell transplantation.
The investigators' preliminary data suggest that low levels of vitamin A directly impact risk of mucosal barrier injury laboratory-confirmed bloodstream infection (MBI-LCBI), likely via decreased gut permeability, and they hypothesize supplemental vitamin A at the time of HSCT can reduce the risk of MBI-LCBI and gastrointestinal graft versus host disease (GI GVHD). A 3x3 dose escalation/de-escalation study design will be used to determine the safety and dosing required to maintain vitamin A levels in the upper quartile of normal range for age at day +30 (± 7 days) with single dose vitamin A supplementation prior to hematopoietic stem cell transplantation.
