    Abstract:
    The use of total parenteral nutrition (TPN) in bone marrow transplant recipients is well recognized. These patients, as a result of treatment with chemotherapy and immunosuppressive agents, undergo catabolic stress. In stressed patients attention has been focused on the optimal calorie: nitrogen ratio of total parenteral nutrition formulations. Theoretically, TPN formulas of low calorie: nitrogen ratio impede body protein catabolism. In bone marrow transplant patients negative nitrogen balance may persist despite high nitrogen intake. The purpose of the present study is to determine the effect of increasing nitrogen intake on nutritional and metabolic parameters in bone marrow transplant patients. The metabolic effect of an increased nitrogen dose during TPN was studied in 33 bone marrow transplant patients, divided into 2 groups. Patients were given total parenteral nutrition formulas providing a protein intake of 1.4 +/- 0.2 g of protein/kg IBW/day for the first group, and 2.3 +/- 0.12 g of protein/kg IBW/day for the II group. Total calories, non protein and protein, were held constant at 40 kcal/kg IBW/day for all patients. Data have been calculated for 4 weeks starting from the first week pretransplant. As we had expected, the patients who are the object of the present study were well nourished at the time of hospital admission, confirming the description of bone marrow transplant recipients published by other transplant centers. Relative body weight, total serum protein, albumin, prealbumin and cholesterol were not significantly different at any study period.(ABSTRACT TRUNCATED AT 250 WORDS)
