title: Serial profile of vitamins and trace elements during the acute phase of allogeneic stem cell transplantation.
abstract: Currently, we utilize vitamins and trace elements formulations that are not prepared specifically for patients receiving hematopoietic stem cell transplantation (HSCT), and adequacy of this strategy has not been evaluated. We prospectively measured blood level of vitamins and trace elements in 15 patients once per week at 6 time points around the acute phase of allogeneic HSCT. We provided standard nutrition support, including administration of parenteral nutrition with vitamin and trace elements formulation in case of impairment of oral intake. Most patients had vitamin B1 deficiency from the start of preparative regimens. Vitamin C deficiency was prominent throughout the acute phase of HSCT and this was significantly associated with high inflammatory markers, C-reactive protein and ferritin. Remarkable vitamin K overload associated with administration of parenteral supplementation and ferritin overload caused by repeated transfusions was observed. Moderate deficiency of zinc was at least partially linked to gastrointestinal loss by diarrhea. We revealed several features of vitamin and trace element status in the acute phase of HSCT and provided a basis for attempts to improve the nutritional condition in HSCT recipients.
