Clinical effect of individualized parenteral nutrition vs conventional method in patients undergoing autologous hematopoietic SCT.

Malnutrition in patients undergoing hematopoietic SCT is known as a risk factor for adverse effects and is directly or indirectly responsible for excess mortality and morbidity. We designed the present study to evaluate the effects of individualized parenteral nutrition (PN) and compare the present method to the conventional PN. Individualized PN based on the Harris-Benedict equation was administered to 30 patients after hematopoietic SCT and was compared with an age, gender and disease matched group of patients who underwent hematopoietic SCT with conventional PN. These two groups were compared on clinical, hematological, nutritional outcomes. Comparing duration of hospital stay (P value<0.0001), infection (P value = 0.01), time to platelet engraftment (P value = 0.02), units of packed cell transfusion (P value = 0.006) and decrease in body weight (P value = 0.004) showed significant differences between the two groups. In conclusion, the use of individualized PN seems more beneficial than conventional PN.
