In seven patients, six with Crohn's disease and one with pancreatitis, two methods of parenteral nutrition were compared: the partial consecutive administration of the components of a parenteral nutrition regimen versus the administration of all nutrients simultaneously. With respect to the consecutive regimen, the simultaneous infusion regimen gave an improvement in the nitrogen balance of 13% and a decrease in urinary lactic acid of about 50%. Urinary excretion of alpha-amino nitrogen, glucose, and fructose was very small in both cases but was slightly lower during the simultaneous infusion regimen. The improvement in the nitrogen balance attained with the simultaneous infusion regimen can be explained by the fact that infused nutrients, especially carbohydrates, cause fewer metabolic disturbances. The simultaneous infusion regimen has three other advantages. The patients rarely complain of headache and nausea, the infusion regimen is markedly simplified and the risk of contamination when nutrients are added to the infusion bottles in the ward is considerably diminished.

21 patients with gastroenterological disease and indication for the use of intravenous nutrition received an elemental diet (ED) for 5-44 days. In 6 out of 8 patients with exacerbation of Crohn's disease remissions were achieved, apart from 3 persistent fistulas. In 5 out of 9 cases with various primary diseases and postoperative intestinal fistulas, spontaneous healing was observed. Furthermore, 2 patients with ulcerative colitis, 1 with radiation enteritis and 1 with pancreatitis were treated with ED. On ED, hemoglobin increased from 11.3 +/- 0.4 (m +/- SEM) to 12.0 +/- 0.5 g% (p less than 0.01) and serum albumin from 2.7 +/- 0.1 to 3.4 +/- 0.1 g% (p less than 0.001). Nitrogen requirements were studied in 11 patients receiving various quantities of ED. Nitrogen balance was found to be in equilibrium or positive in 7 patients, and negative in 4. In one patient with severe ulcerative colitis, fecal nitrogen losses were higher than urinary nitrogen losses. The unpleasant taste of ED resulting from free amino acids limited the ED supply in 3 patients and led to premature ending of ED administration in 3 other patients. In such cases ED may be given by nasogastric tube feeding. From the results presented it appears that ED is indicated in Crohn's disease and intestinal fistulas. However, the results obtained require confirmation by further observations and comparison with an intravenously fed control group.

Pancreatitis was induced in 11 miniature pigs by infusing a bile salt-trypsin solution into the pancreatic duct. Seven animals served as sham-operated controls. Serum ionized calcium, total calcium, albumin, total protein, inorganic phosphorus, urea nitrogen, magnesium, insulin, glucagon, and hematocrit were determined every six to 12 h over a period of one week in both test and control animals. We observed significant decreases in ionized and total calcium, modest decreases in albumin, and significant increases in the inorganic phosphorus, urea nitrogen, and hematocrit in the pancreatitic pigs. The latter two findings were consistent with early acute hypovolemia. Glucagon and insulin appeared to play no role in the hypocalcemia. Glucagon concentrations increased to the same degree in both test and control animals, probably as a result of the stress of being handled and operated on. The highest concentrations of inorganic phosphorus and the lowest concentrations of both ionized and total calcium were seen 18 h after the induction of pancreatitis in the test animals. These findings suggest that parathyrin (parathormone) was not being secreted in adequate amounts, or that the target organs were unresponsive to parathyrin.

The value of conservative treatment in a case of chronic advanced renal failure was investigated in a 5-year-old girl with congenital hypoplastic kidneys. Before treatment the patient was severely anorexic and her plasma urea nitrogen was 180 mg/100 ml. Protein restriction alone was fruitless. After a transitional period on total parenteral therapy the patient was put on a maintenance oral diet, where an energy-rich diet was supplemented with essential amino acids including histidine. Plasma urea nitrogen dropped and stayed at about 50 mg/100 ml during the whole treatment in spite of a rising plasma creatinine from 10 to 24 mg/100 ml. The general condition of the patient normalized as she went into an anabolic state with weight gain and growth in height. The nitrogen balance studied in two different periods was positive. An acute attack of pancreatitis, secondary to hyperparathyroidism, ended the patient's life after 22 months of treatment.

Three hundred patients with acute pancreatitis have been studied. Pancreatitis was associated with alcoholism in 207, biliary tract disease in 51 and other conditions in 42. Twenty-two patients died, and an additional 34 patients required more than one week of treatment in the intensive care unit. Retrospective analysis of the first 100 patients identified 11 objective findings which correlated with the occurrence of serious illness or death. They were, on admission, age over 55 years, blood glucose level over 200 milligrams per cent, white blood count over 16,000 per cubic millimeter, serum lactic dehydrogenase level over 350 International units per liter and serum glutamic-oxalacetic transaminase level over 250 Sigma Frankel units per cent. During the initial 48 hours of therapy, the findings were hematocrit value decrease over 10 percentage points, serum calcium level below 8 milligrams per cent, base deficit over 4 milli-equivalents per liter, a blood urea nitrogen level increase over 5 milligrams per cent, estimated fluid sequestration over 6 liters and arterial oxygen tension less than 60 millimeters of mercury. Prospective application of these signs in the latter 200 patients permitted the accurate early identification of those with severe pancreatitis. Only one of 162 patients with fewer than three of these early features was seriously ill or died, while 24 of 38 patients with three or more early positive findings were seriously ill or died. The objective early identification of patients with severe pancreatitis permits more vigorous management of this group and also provides a basis for the selection of patients for the evaluation of proposed improved therapies. Percutaneous peritoneal dialysis in severe pancreatitis was evaluated in ten patients, with three or more positive early signs, who were randomly assigned to dialysis or continued conventional care. Morbidity was strikingly reduced in patients who underwent dialysis, and while death or more than nine days of intensive care occurred in two of five patients who did not receive dialysis, all five patients having dialysis recovered after fewer than nine days of intensive care treatment. Serious illness or death occurred in 31 of the first 100 patients but in only 26 of the more recent 200 patients. There has been a similar fall in mortality from 15.0 to 3.5 per cent. Factors which may contribute to this improvment include the objective early identification of patients with severe disease, the avoidance of early laparotomy whenever practical, the prolongation of nasogastric suction until all evidence of pancreatic inflammation has resolved, careful monitoring of respiratory function and early treatment of pulmonary complications and peritoneal dialysis in patients with severe disease.

The current review has summarized current data relevant to the nutritional support of patients with acute pancreatitis. Selection of the most appropriate form of nutritional support for patients with acute pancreatitis is intimately linked to a thorough understanding of the effects of various forms of enteral and parenteral nutrition on physiologic exocrine secretory mechanisms. Two basic concepts have emerged from the multiple studies that have addressed these issues to date: 1, enteral feeds should have low fat composition and be delivered distal to the ligament of Treitz to minimize exocrine pancreatic secretion and 2, parenteral substrate infusions, alone or in combinations similar to those administered during TPN, do not stimulate exocrine pancreatic secretion. From a practical standpoint, most patients with acute pancreatitis are diagnosed by nonoperative means and will manifest some degree of paralytic ileus during the early phase of the disease. Therefore, jejunal feeds are usually not a therapeutic option early in the course of this disease. On the basis of the clinical studies reviewed herein we propose general guidelines for the nutritional support of patients with acute pancreatitis: 1, most patients with mild uncomplicated pancreatitis (one to two prognostic signs) do not benefit from nutritional support; 2, nutritional support should begin early in the course of patients with moderate to severe disease (as soon as hemodynamic and cardiorespiratory stability permit); 3, initial nutritional support should be through the parenteral route and include fat emulsion in amounts sufficient to prevent essential fatty acid deficiency (no objective data exist to recommend specific amino acid formulations); 4, patients requiring operation for diagnosis or complications of the disease should have a feeding jejunostomy placed at the time of operation for subsequent enteral nutrition using a low fat formula, such as Precision HN (Sandoz, 1.3 percent calories as fat), Criticare HN (Mead Johnson, 3 percent calories as fat) or Vivonex High Nitrogen (Norwich Eaton, 0.87 percent calories as fat), and 5, oral feedings should be low fat in composition and should be reinstituted using traditional clinical criteria, including the symptoms of the patient, physical examination and computed tomographic appearance of the pancreas (clinicians should bear in mind the well documented exocrine stimulatory effects of even low fat oral feeds and the risks of early refeeding). These general guidelines must be individualized to incorporate what is perhaps the most important clinical variable--the premorbid nutritional state of the patient.(ABSTRACT TRUNCATED AT 400 WORDS)

The malnourished alcoholic patient requires frequently hospitalization for treatment and an adequate nutritional support is necessary for recovery of their health. The objective of the present study was to evaluate the nutritional value of an enteral diet based on "soya milk", corn sugar, coconut oil and water. Seven alcoholics, males, with 36.4 year mean age, without any clinical evidence of hepatic cirrhosis and/or pancreatitis, were submitted to three periods of metabolic nitrogen balance (NB), with multiple levels of protein intake (0.4, 0.6 and 0.8 grams of proteins/kg of body weight/day). The nitrogen intake (NI), the fecal nitrogen (FN) and the urinary nitrogen (UN) were determined, and the NB and protein digestibility value were calculated. The net protein utilization (NPU) was calculated by correlation studies between the NI and NB, with a value of 101.3%. The mean true digestibility was 100.1% and the mean requirement for that population was 0.5g protein/kg of body weight/day. Using a 97.5% confidence limit, the protein requirement of the enteral diet was calculated to be 0.8g protein/kg of body weight/day. The enteral diet based on "soya milk" can be profitable for this group of patients. It is a good alternative for use in enteral nutrition, easily available, well tolerable, and of high biological value.

Continuing researches on the monitoring of acute phase proteins (A.P.P.) as markers of septic risk in the surgery patient, a series of 50 patients suffering from pathological processes classifiable as follows has been examined: 1) acute biliary pancreatitis 18 cases; 2) acute hepatobiliary pathology without pancreatic impairment 26 cases; 3) burn 2 cases; 4) particularly serious sepsis in immunodepressed subjects 4 cases. The constant finding of increased values of PCR, fibrin, cerul, alpha 1-Trip in the surgery patient at septic risk and their normalisation after treatment is, in single cases, particularly significant and perfectly consistent with the clinical entity of the infectious process. In immunodepressed surgery patients showing deficiency in nitrogen balance and suffering from endotoxin shock a marked, persistent decrease in alpha 2-Macro, Tranfs, Albu and Prealbu parameters was noted. The reduction in these four A.P.P. can, in the Authors' experience, be considered a diagnostic indicator of sepsis of extreme gravity and an unfavourable prognosis finding regarding the course of the disease process.

Normothermic ischemia tolerance is an important aspect of organ procurement and transplantation. The function of pancreas and kidney autografts was investigated in totally pancreatectomized or nephrectomized canine recipients. In 30 dogs the left limb (tail) of the pancreas was removed but left in the abdominal cavity after cessation of blood flow to produce warm ischemia for 30, 60, and 120 min (10 dogs at each time point), and then was flushed with cold Ringers' lactate and transplanted to the iliac vessels. Twenty dogs with fresh pancreatic transplants were controls. The success rate of pancreas transplants with warm ischemia of 1/2 and 1 hr was the same as that of controls (80%); however, after 1 hr normothermia 5/10 dogs had episodes of hyperglycemia for 1 week before glucose levels came back to normal. All but one graft with 2 hr warm ischemia failed. Intravenous glucose tolerance test (IVGTT) mean (+/- SEM) K values were not different in the successful groups, i.e., no warm ischemia: -1.55 +/- 0.15%; 1/2 hr warm ischemia: -1.81 +/- 0.18%; 1 hr warm ischemia: -1.64 +/- 0.09%. Amylase levels increased after transplant with maximum values at Day 2, then returned to normal, but the levels remained elevated in recipients of grafts subjected to longer normothermia with evidence of pancreatitis after 1 hr warm ischemia. Fifteen kidney grafts were treated similarly with warm ischemia exposure of 1/2 hr (n = 9) and 1 hr (n = 6) before being flushed and autotransplanted, and were compared to 16 fresh kidney transplants. After 1/2 hr warm ischemia none of the kidney grafts failed but 78% of the recipients had elevated serum creatinine and urea nitrogen levels which returned slowly to normal after 3 to 4 weeks. There was only one long-term survivor after 1 hr warm ischemia. Thus the pancreas seems to be more resistant to warm ischemia damage than is the kidney. This difference should be taken into consideration in regard to organ procurement for clinical transplantation.

The use of total parenteral nutrition (TPN) in the treatment of 73 patients with acute severe pancreatitis was prospectively studied during a two year period. Patients were divided into three groups on the basis of calorie substrate used. Glucose and twice weekly lipid infusion (glucose based) were used in 60 per cent; 27 per cent required daily lipid infusion (lipid based), and 13 per cent received no lipid because of pre-existing hyperlipemia or thrombocytopenia (no lipid). Nutritional indices (albumin, transferrin and total lymphocyte count) were initially abnormal in more than 80 per cent of patients, and 50 per cent had three or more of Ranson's criteria. After TPN, 81 per cent had improved nutritional indices, and none had hypertriglyceridemia or aggravation of pancreatitis develop. Patients who received lipid based or no lipid had higher insulin requirements (p less than 0.01) than those receiving mainly glucose. Mortality was increased tenfold (2.5 versus 21.4 per cent, p less than 0.01) in patients who did not achieve positive nitrogen balance. We conclude that TPN, either lipid or glucose based, is a safe and effective therapy to reverse the malnutrition of acute pancreatitis and that failure to achieve positive nitrogen balance is associated with increased mortality.
