Effectiveness of central parenteral nutrition versus peripheral parenteral nutrition plus enteral nutrition in reversing protein-energy malnutrition in children with advanced neuroblastoma and Wilms' tumor: a prospective randomized study.

The effectiveness of central parenteral nutrition (CPN) versus peripheral parenteral nutrition (PPN) plus enteral nutrition in reversing protein-energy malnutrition was evaluated in 19 children (nine CPN, 10 PPN) with advanced neuroblastoma or Wilms' tumor. Weekly dietary, anthropometric, and biochemical measurements were compared for 15 patients (eight CPN, seven PPN) who completed more than 25 days of nutrition support. The groups had similar mean energy and protein intakes (CPN: 95 +/- 5% of healthy children, 2.5 +/- 0.3 g/kg; PPN: 102 +/- 5% of healthy children, 2.9 +/- 0.3 g/kg). Increases in weight (p less than 0.001), subscapular skinfold thickness (p less than 0.001), albumin (p less than 0.05), and transferrin (p less than 0.05) for the first 28 days were significant and did not differ between groups. Fever, sepsis, elevated SGOT, and severe anemia occurred with both CPN and PPN. PPN resulted in subcutaneous infiltrations and more psychological trauma. PPN with enteral nutrition seems most appropriate for short term intravenous nutrition support or as a temporary substitute for CPN; CPN is preferred for long-term support.

Lower glycemic response to sucrose in the diets of children with type 1 diabetes.

OBJECTIVE: To compare glycemic responses of isocaloric mixed meals containing 2% and 17% sucrose in children with type 1 diabetes who had fasting euglycemia. STUDY DESIGN: Nine children (11 to 16 years) with type 1 diabetes were randomized in a crossover design to receive 2 isocaloric diets (2% or 17% sucrose) in the Clinical Research Center. In the 2% sucrose diet, starch isocalorically replaced sucrose. RESULTS: Fasting euglycemia was comparable on both study days (mean +/- SEM: 2% sucrose, 5.0 +/- 0.3 mmol/L or 90 +/- 5 mg/dL; 17% sucrose, 5.0 +/- 0.3 mmol/L or 91 +/- 6 mg/dL). The 17% sucrose diet resulted in a lower glycemic response than the 2% sucrose diet over the 4-hour study period (area under glucose response curve: mean +/- SEM, 37 +/- 3.5 mmol/L x 4 h vs 42 +/- 4.7 mmol/L x 4 h, P = .01). Peak blood glucose response was earlier and lower (2.2 to 2.8 mmol/L, 40 to 50 mg/dL) with the 17% sucrose diet. CONCLUSIONS: Sucrose in moderate amounts, isocalorically exchanged for starch, lowered glycemic response between breakfast and lunch in children who were euglycemic before breakfast. These data refute concerns about adverse glycemic effects of sucrose and support the use of sucrose-containing foods in the context of a healthy meal plan.

Short- and long-term effectiveness of enteral and parenteral nutrition in reversing or preventing protein-energy malnutrition in advanced neuroblastoma. A prospective randomized study.

The effectiveness of enteral and parenteral nutrition regimens in preventing or reversing protein-energy malnutrition (PEM) and in preventing treatment delays was evaluated in 32 children receiving treatment for newly diagnosed Stage III (3 patients) and IV (29 patients) neuroblastoma. Ten of 18 malnourished patients were randomized to central parenteral nutrition (CPN) and 8 to peripheral parenteral nutrition (PPN) plus enteral nutrition for 4 weeks and then received enteral nutrition (EN: intense nutrition counselling, oral foods and supplements) for weeks 5 through 10. Ten of 14 nourished patients received EN and 4 CPN for 4 weeks and EN thereafter. Dietary, anthropometric and biochemical measurements were determined for weeks 0, 1, 2, 3, 4, 7, and 10 for 24 patients who completed the protocols. In malnourished patients, both CPN (seven patients) and PPN (seven patients) were effective in reversing PEM in the first 4 weeks; thereafter, EN effectively maintained nutritional gains in both groups. In nourished patients, EN (seven patients) was not as effective as CPN (three patients) in preventing PEM during the first 4 weeks; afterwards, EN maintained gains in the CPN group but did not promote needed increases in weight nor fat reserves in the EN group. Patients supported by parenteral nutrition (PN, weeks 1-4) had fewer treatment delays (2/17, 12%) than EN patients (4/7, 57%, P less than 0.05). These data indicate that PN reverses or prevents PEM and prevents treatment delays during the first 4 weeks of intense oncologic treatment and provides nutritional benefits which can be maintained with EN thereafter.

Integration of nutrition support into oncologic treatment protocols for high and low nutritional risk children with Wilms' tumor. A prospective randomized study.

Benefits and risks of nutrition support were evaluated in 31 malnourished children with newly diagnosed Wilms' tumor managed according to the third National Wilms' Tumor Study protocol. Patients were classified at diagnosis as being at high nutritional risk (HNR, n = 19) or low nutritional risk (LNR, n = 12). Ten HNR patients were randomized to central parenteral nutrition (CPN) and nine HNR patients were randomized to peripheral parenteral nutrition (PPN) plus enteral nutrition (EN) for 4 weeks of initial intense treatment and EN (nutritional counseling, oral foods and supplements) thereafter. Thirteen HNR patients (seven CPN, six PPN) completed the protocol. Twelve LNR patients received EN; 11 Stage I malnourished patients were randomized to 10 or 26 weeks of chemotherapy. Dietary, anthropometric, and biochemical data were determined for HNR patients at weeks 0-4, 6, 13, 19, and 26 and for LNR patients at weeks 1, 2, 5, and 26. In HNR patients, adequate parenteral nutrition support reversed protein energy malnutrition (PEM), and prevented chemotherapy and radiotherapy delays due to granulocytopenia. CPN was superior to PPN in reversing PEM: energy intake, weight gain, and retinol binding protein were higher (P less than 0.05). LNR patients lost weight and fat reserves in the first 2 weeks of treatment; depletion persisted at week 5, and 25% had chemotherapy delays. Thereafter, EN reversed PEM in patients with both chemotherapy regimens. These data suggest that CPN is preferable during initial intense treatment for HNR patients, and that, although EN is ineffective in preventing depletion and treatment delays in the first 5 weeks of treatment for LNR patients, it is effective thereafter.

Effect of nutrition staging on treatment delays and outcome in Stage IV neuroblastoma.

The effect of the state of nutrition of 18 children with Stage IV neuroblastoma at diagnosis and during initial therapy, was evaluated with respect to treatment delays, drug dosage alterations, tumor response, days to first event (relapse or death), and survival. All patients received similar therapy (CCSG protocol CCG 371). Based on nutrition staging at diagnosis, nine were classified as malnourished; four were randomized to receive total parenteral nutrition (TPN) and four peripheral parenteral nutrition plus enteral nutrition for 28 days (through 2 chemotherapy courses), and one died before randomization. Nine were nourished at diagnosis; seven received a comprehensive enteral nutrition program and two received TPN. By life-table analysis, the duration of remission was significantly greater in the nourished than the malnourished (P less than 0.01) and a trend towards improved survival was evident at one year (P = 0.08). The median length of survival for children nourished at diagnosis was approximately 12 months, whereas those malnourished had a median survival of only 5 months. Nine children remained nourished or were becoming renourished during the first 21 days of therapy, and one of these had treatment delays and decreased drug dosages. Seven were becoming malnourished or remained malnourished during this period and six had treatment delays (P less than 0.01). These data support the idea that nutrition staging at diagnosis and during initial treatment should be an integral part of protocol design and initial evaluation of children with Stage IV neuroblastoma.
