A prospective search for factors that would anticipate successful nutritional repletion was undertaken in patients with advanced malignant diseases of the upper gastrointestinal tract. After two weeks of intravenous hyperalimentation, increasing serum transferrin levels, total lymphocyte counts, and, to a lesser extent, arm muscle circumferences predicted an improved quality of survival, whereas declines in these factors were seen in patients who died. Skin tests, T-lymphocyte counts, albumin levels, and other anthropomorphic measurements were not predictive. The single most useful test was the serum transferrin: in only one patient did it not reflect the eventual outcome of therapy.

This study considers the effects of glucose, during amino acid infusion, on protein-sparing and amino acid utilization after proctocolectomy or abdominoperineal resection of the rectum. Body composition and plasma amino acids were compared in each of three groups of patients before and 15 days after surgery who were receiving, in addition to restricted oral diets: 1) no hyperalimentation 2) parenteral amino acids or 3) hypertonic glucose plus amino acids. Parenteral solutions were given by central venous catheter. Infusion of amino acids alone spared body protein but branch chain amino acids (i.e. valine, isoleucine and leucine) and also phenylalanine, methionine and proline were increased well above the normal values. There were no increases in liver proteins other than for the "acute phase" type. In contrast, full hyperalimentation spared more body protein and fat, restored plasma amino acids to normal while plasma cortisol and acute pohase proteins were lower. Plasma transferrin, prealbumin and retinol binding protein were increased, as previously shown, while clinical outcome was more favorable. It is concluded that glucose is essential to ensure optimum utilization of amino acids for both muscle and liver protein synthesis and, therefore, intravenous hyperalimentation is preferable to amino acids alone after major colorectal surgery.

The effect of intravenous hyperalimentation on the nutritional status of 84 cancer patients treated at the Istituto Nazionale Tumori, Milan, has been evaluated. The body weight increased in 78% of patients, mid upper arm circumferance in 93%, triceps skinfold in 73%, mid upper arm-muscle circumference in 73%, creatinine/height index in 30%, serum albumin in 32%, transferrin in 35%, total peripheral lymphocytes in 38%. Lymphocyte blastogenesis increased in 74% of the patients examined and skin tests were converted from negative to positive in about 20% of patients. In addition 8 our of 18 patients responsive to IVH benefited from chemotherapy and/or radiotherapy indicating that the nutritional repletion of the host did not significantly affect the growth of the tumor. These findings support the opinion that neoplastic cachexia may depend partially on malnutrition and can be often reversed by IVH. Moreover, IVH might have an adjunctive role as potentiator of chemotherapy which however must be confirmed by clinical trials.

We studied the effects of the new amino acid solution MRX-III on the nutritional status and nitrogen metabolism of rats with chronic renal failure (CRF) in comparison with those of a general amino acid solution (MPR-F). The essential amino acids/non-essential amino acids ratio was 3.21 for MRX-III and 1.09 for MPR-F. Rats with CRF, induced by 7/8 renal ablation, were divided into 6 groups of 8 rats each receiving total parenteral nutrition (TPN) containing MRX-III or MPR-F at a non-protein calorie/nitrogen ratio (Cal/N) of 300, 600 or 900 for 7 d. The rats were infused with test solutions containing the same amounts of non-protein calories. The cumulative nitrogen balance, as a nutritional index, in the MRX-III group was significantly higher than that in the MPR-F group at the Cal/N of 600 or 900, and the plasma albumin level at the Cal/N of 300. The plasma transferrin levels at the Cal/N of 900 in the MRX-III groups were significantly higher than those in the corresponding MPR-F groups. At all Cal/N, the MRX-III groups showed low levels of blood urea nitrogen and urinary excretion of ammonia and urea nitrogen as compared with the MPR-F groups at the same Cal/N. The plasma amino acid concentration profiles in the MRX-III groups after TPN showed greater similarity to that in the Normal group as compared with the profiles in the corresponding MPR-F groups. No aggravation of renal failure was observed in any TPN groups during TPN. These results indicate that, in rats with CRF undergoing hyperalimentation, the effects of MRX-III on the nutritional status and nitrogen metabolism are superior to those of the general amino acid solution, MPR-F. It is suggested that MRX-III could safely provide adequate amounts of nitrogen during hyperalimentation.

Few studies have tried to characterize the efficacy of parenteral support of critically ill infants during short period of intensive care. We studied seventeen infants during five days of total parenteral hyperalimentation. Subsequently, according to the clinical conditions, the patients received nutritional support by parenteral, enteral route or both up to the 10th day. Evaluations were performed on the 1st, 5th, and 10th days. These included: clinical data (food intake and anthropometric measurements), haematological data (lymphocyte count), biochemical tests (albumin, transferrin, fibronectin, prealbumin, retinol-binding protein) and hormone assays (cortisol, insulin, glucagon). Anthropometric measurements revealed no significant difference between the first and second evaluations. Serum albumin and transferrin did not change significantly, but mean values of fibronectin (8.9 to 16 mg/dL), prealbumin (7.7 to 18 mg/dL), and retinol-binding protein (2.4 to 3. 7 mg/dL) increased significantly (p < 0.05) from the 1st to the 10th day. The hormonal study showed no difference for insulin, glucagon, and cortisol when the three evaluations were compared. The mean value of the glucose/insulin ratio was of 25.7 in the 1st day and 15. 5 in the 5th day, revealing a transitory supression of this hormone. Cortisol showed values above normal in the beginning of the study. We conclude that the anthropometric parameters were not useful due to the short time of the study; serum proteins, fibronectin, prealbumin, and retinol-binding protein were very sensitive indicators of nutritional status, and an elevated glucose/insulin ratio, associated with a slight tendency for increased cortisol levels suggest hypercatabolic state. The critically ill patient can benefit from an early metabolic support.

We investigated the feasibility of early postoperative enteral diet after esophagectomy. Sixteen patients who underwent esophagectomy followed by reconstruction using gastrictube were divided into two groups based on nutritional protocol after surgery: either total parenteral nutrition (TPN) or enteral diet (ENT). TPN patients were nutritionally maintained with only intravenous hyperalimentation. The ENT group was challenged mainly with enteral diet started on day 1. Serum rapid turnover proteins (RTPs; transferrin, prealbumin, retinal-binding protein, and insulin like growth factor-1: IGF-1) were measured two days before (preoperative value) and 3, 5, 7, 10, and 14 days after surgery. The percent value of the four RTPs were decreased at day 3 and gradually recovered. There were no significant differences between the groups according to four RTPs. No major complications due to early enteral diet occurred in ENT patients. We conclude that early enteral diet is nutritionally adequate and might be recommended as standard nutritional care after subtotal esophagectomy.
