Vitamin D deficiency is common in childhood, pervasive before and after bone marrow transplant, and associated with increased incidence of graft-versus-host disease (GVHD) and decreased survival in patients undergoing hematopoietic stem cell transplantation (HSCT). Numerous barriers impede replacement, including malabsorption secondary to gut GVHD, mucositis, inability to take capsules, kidney disease, liver disease, and infection; many patients remain refractory despite vitamin D therapy. We hypothesized that a different formulation of cholecalciferol, administered on the tongue as a readily dissolving oral thin film (OTF), would ease administration and facilitate therapeutic vitamin D levels (>35 ng/mL) in refractory patients. In this prospective pilot study, we evaluated 20 patients post-HSCT (range: day +21 - day +428 at enrollment) with serum vitamin D levels 📄 Download the PDF from VitaminDWiki
