Biochemical indices for the assessment of nutritional status during hematopoietic stem cell transplantation: are they worth using? A single center experience.

Hematopoietic stem cell transplantation (HSCT) is being used increasingly in an attempt to cure many hematological disorders, solid tumors and autoimmune diseases. One of the major challenges in the post-transplant period is nutrition. The purpose of this investigation was to assess changes in the biochemical indices of nutritional status during HSCT and compare them with acute-phase protein levels to find the best parameters for nutritional support qualification. Nutritional status was assessed in 54 patients during autologous (30 cases) and allogeneic (24 cases) transplantation. Fifteen patients had to be treated with total parenteral nutrition (TPN), eight of them needing prolonged hospitalization. All nutritional indices and acute-phase protein levels were evaluated during the day before the beginning of conditioning regimen, after chemotherapy completion and every 7 days until engraftment, at least three times after stem cells infusion. Wilcoxon test and canonical analysis were used for statistical analyses. The measurement of retinol-binding protein and transferrin can be useful for nutritional assessment during autologous and allogeneic HSCT, respectively. Prealbumin level, measured 8 days after the end of conditioning regimen, is helpful in making a decision about starting TPN.Bone Marrow Transplantation (2007) 40, 567–572; doi:10.1038/sj.bmt.1705767; published online 16 July 2007 [ABSTRACT FROM AUTHOR]
