The study included 13 infants under one year complaining of acute gastroenteritis and dehydration who were still in oliguria or anuria 6 hours after rehydration was initiated. They were given a single dose of furosemide at the rate of 1 mg/kg and indices of U/P of urea and osmolarity, ratio urea/plasmatic creatinine, urinary volume, natriuresis and evolution of urea plasmatic figures and of creatinine were determined. Four patients showed no response to the diuretic; all of them died and through clinical and histopathologic evaluation they were classified as having acute renal insufficiency (IRA). The nine patients showing response to the drug with an increase of 5 to 30 times the control figure for urine and natriuresis showed an index U/P of urea of 5.52 +/- 3.82, U/P of osmolarity of 1.32 +/- 09, ratio urea/plasmatic creatinine of 58.7 +/- 19.8 and the figures for urea and creatinine in blood turned normal within 2 to 4 days. This was classed as prerenal azotemia (APR). It is thus concluded that furosemide appears to be a good parameter to make an early differentiation of cases with IRA, but that this measure, the same as the rest of the indices cannot show an absolute value since there are important variations in each individual.

Total hydroxyproline/creatinine ratio (THP:Cr) was measured in random urine specimens from 18 infants with gastroenteritis. THP:Cr was sometimes increased during the acute phase of the illness and the reasons for this are discussed. Seven patients failed to thrive after the acute phase and THP:Cr was low in all of these. The test appears to be a sensitive indicator of the onset of failure to thrive, and it is suggested that it may be of value in the management of these patients.

To explore different types of metabolic acidosis in acute gastroenteritis of infancy, and to correlate it with nutritional status and clinical outcome, we examined prospectively 27 consecutive infants admitted with moderate to severe dehydration and arterial blood pH less than or equal to 7.20. Serum anion gap, creatinine, divalent cations (Ca, Mg), and the anionic contribution of total protein, lactate, and phosphate as well as ketones and urine pH, were determined on admission and compared with age-matched controls. Twenty infants (Group A) presented with normal anion gap (13.1 +/- 2.7) associated with hyperchloremia (115.8 +/- 4.2 mmol/L, p less than 0.01) and diminished bicarbonate (9.7 +/- 2.4 mmol/L, p less than 0.01), compared with controls. The other seven infants (group B) demonstrated an increased anion gap (26.7 +/- 3.2, p less than 0.01), associated with significant elevations of lactate (3.4 +/- 0.7 mmol/L, p less than 0.001), total protein (93.4 +/- 12.3 g/L, p less than 0.01), as well as phosphate (2.3 +/- 0.2 mmol/L, p less than 0.01) and creatinine (164.9 +/- 45.1 mumol/L, p less than 0.001), compared with controls. No significant deviations of blood divalent cations or ketones were noted in both groups. Urine pH was less than or equal to 5.5 in all subjects. Analysis of nutritional status and clinical outcome in both groups revealed significant differences.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative examinations of renal function using inulin- and endogenous creatinine-clearance tests in 5 pigs showed nearly identical values of glomerular filtration rate (GFR). Based on this relation 79 healthy pigs, weighting 2 kg to 230 kg were investigated using the creatinine-clearance test for determination of normal values of GFR and urine flow rate (Vu) as well as renal excretion (E), renal clearance (Clr) and fractional excretion (FE) of urea, sodium, potassium, calcium, phosphorus, glucose and lactate. The renal excretion of creatinine (E-Creat) was closely correlated with the body weight. Therefore it is possible to use the body weight for estimation of E-Creat and to calculate GFR and Vu using plasma and urine concentrations of creatinine independent of a timed volumetric urine collection. Subsequently E, Clr and FE of electrolytes or other endogenous substances can be evaluated. Finally the practicability of this procedure for detection of disturbed glomerular filtration or tubular reabsorption was demonstrated in piglets suffering from colidiarrhoea and/or transmissible gastroenteritis.

We studied urinary acidification daily during the hospital course of 16 infants with acute gastroenteritis and metabolic acidosis. Urine pH value on admission was higher than 5.5 in 14 (87%) patients. We hypothesized that inappropriate urinary acidification was due to sodium deficiency and inadequate sodium delivery to the distal nephron. Forty-one urinary samples were collected during metabolic acidosis. The mean pH of 24 urine samples with sodium concentration less than 10 mmol/L was significantly higher than the pH of 17 samples with sodium concentration greater than 10 mmol/L (6.04 +/- 0.06 vs 5.19 +/- 0.1; p less than 0.001). The urine ratios of titratable acid to creatinine and of total acidity to creatinine were significantly higher in urine samples containing more sodium (p less than 0.02), whereas the ammonium/creatinine ratio was not. After administration of furosemide or correction of the sodium deficit, appropriate acidification was observed. We conclude that impaired urinary acidification is frequently found during metabolic acidosis in infants with acute gastroenteritis and results from a sodium deficit rather than from transient distal renal tubular acidosis.

This study records our experience with 40 infants who developed acute renal failure in a tropical environment over a period of 2 years. All the patients required intermittent peritoneal dialysis. Septicaemia (88%) and acute gastroenteritis (55%) constituted the leading causes of acute renal failure. Haemolytic uraemic syndrome was present in six (18%) patients. An elevated serum creatinine (85%), metabolic encephalopathy (75%), uncompensated metabolic acidosis (75%) and hyperkalaemia (48%) were the major indications for dialysis, while fluid overload was present in only 18% of the infants. Intermittent peritoneal dialysis was used in all the patients and was found to be effective. Procedural complications were minor and infrequently encountered. The clinical course and laboratory data consistent with haemolytic uraemic syndrome was observed in six patients, and acute tubular necrosis was the predominant renal lesion in the remainder. Mortality was 75%. The aetiology of acute renal failure in infants in the tropics differs significantly from that in the West, and even within a given country marked regional variations exist.

A 3-year-old girl is reported on who underwent laparotomy for ileocaecal intussusception elsewhere one week following severe gastroenteritis. Immediately after surgery, she developed haemolytic-uraemic syndrome with haemolytic anaemia, thrombocytopenia, increase of urea and creatinine and anuria as well as subsequent peritonitis, enterocolitis and sepsis. Following relaparotomy with establishment of ileostomy, peritoneal dialysis for several days was carried out for treatment of the haemolytic-uraemic syndrome. This case demonstrates that the haemolytic-uraemic syndrome can be treated effectively by peritoneal dialysis despite fresh bowel anastomoses, and that simultaneously occurring peritonitis can be managed by intraperitoneal administration of antibiotics via dialysis fluid.

150 infants aged under 6 months and admitted to hospital with acute gastroenteritis were treated with rice water (RW), rice-based electrolyte solution (RES), and the glucose electrolyte solution (GES) recommended by the World Health Organisation. Two-thirds of the patients were moderately dehydrated and only 8% had positive stool culture. Vomiting, present in 11%, did not interfere with successful oral rehydration. Before treatment serum electrolytes and other biochemical variables were similar in the three groups. After 48 h of treatment the blood urea nitrogen and serum creatinine were lower (p less than 0.05) in the RW and RES group than in the GES group. Serum potassium was also lower in the RW than in the RES group. RW and RES were superior to GES in reducing the frequency and volume of stool output and in producing weight gain.

Alterations in serum ionized and total calcium, magnesium, and phosphate concentrations, during recovery from acute dehydrating gastroenteritis, were studied. Fifteen children with acute dehydrating gastroenteritis had serum concentrations of ionized and total calcium, magnesium, phosphate, sodium, potassium, chloride, urea, creatinine, and albumin, as well as acid-base status, evaluated during rehydration and up to 72-h postadmission. The total serum calcium corrected for albumin did not change significantly during rehydration and remained within the normal range. Although serum ionized calcium fell significantly at 24 and 72 h, its concentration was not sufficiently decreased to cause symptomatic hypocalcemia. Serum ionized calcium correlated significantly with pH (r = -0.57), bicarbonate (r = -0.63), and albumin (r = +0.65), but not with total serum calcium, magnesium, and phosphate. Serum magnesium remained within the normal range during the study period. Serum phosphate was increased on admission (2.64 +/- 0.77 mmol/L), decreased by 12 h (to 0.84 +/- 0.32 mmol/L), and then followed by a gradual increase. This study suggests that changes in serum ionized calcium in dehydrating gastroenteritis are not of clinical significance. However, changes in serum phosphate concentration need further evaluation.

The main purpose of this study was to evaluate the effectiveness of an oral fluid therapy alone or combined with parenteral administration of a 5% dextrose solution to attenuate the clinical signs and the pathophysiological consequences of transmissible gastroenteritis in neonatal piglets. Eighteen two day old conventional piglets were infected with transmissible gastroenteritis virus while six others were used as controls (Group 1). At the onset of diarrhea, infected piglets were divided into three groups of six (Groups 2, 3 and 4). Piglets in group 2 were not treated and were fed a milk replacer ad libitum. Piglets in group 3 were removed from the milk replacer and placed on an oral glucose-glycine-electrolyte solution ad libitum. Those in group 4 were placed on oral fluid therapy and received a 5% dextrose solution intraperitoneally at the rate of 25 mL/kg of body weight once a day. Blood samples were collected in heparin within minutes after the infected piglets became comatose and from the controls at four or five days of age. The following variables were measured: packed red cell volume, blood pH, total plasma protein and bicarbonate, blood urea nitrogen, and plasma glucose, creatinine, chloride, inorganic phosphorus, sodium, potassium, magnesium and calcium. Vomiting and diarrhea appeared 12 to 24 hours postinoculation in the infected piglets. There was a sudden and rapid progression into a comatose and moribund state one or two days later whether the infected piglets were treated or not.(ABSTRACT TRUNCATED AT 250 WORDS)
