Seven hundred fifty-eight unselected children entered into the United Kingdom Medical Research Council acute lymphoblastic leukaemia UKALL VIII Study and Trial were studied for differences in early treatment-related toxicity according to the type of intramuscular L-asparaginase received. Two hundred seventy-five received a product obtained from Escherichia coli and 483 the enzyme from Erwinia chrysanthemi. The E. coli patients had a significantly higher incidence of neurotoxicity, pancreatitis, and life-threatening sepsis (4%, 2%, and 20%, respectively) when compared with the Erwinia group (2%, 0%, and 18%). Severe hypersensitivity was seen in one patient from both groups and the incidence of glucose intolerance was not significantly different. These findings indicate that E. coli asparaginase may be more toxic. With a minimum follow up of 4 1/2 years there is no evidence that either product has made a significantly different contribution to disease-free survival.

We investigated the impact of norepinephrine administration on hemodynamics, oxygen metabolism and renal function in patients in severe septic shock. PATIENTS AND METHODS. Twenty-six patients with extremely low resistance who were between 24 and 87 years of age were included in the study. In 7 patients, acute necrotizing pancreatitis and superinfection was diagnosed; 19 patients suffered from diffuse peritonitis. The entrance criteria for the study were: a mean arterial pressure (MAP) of below 60 torr or, in chronic hypertensive patients, a decrease in systolic pressure of more than 50 torr compared to previous values, despite volume optimization, and dopamine greater than 20 micrograms/kg per min and cumulative doses of dopamine/dobutamine greater than 30 micrograms/kg per min, respectively. Cases with tachycardia greater than 140/min were also included in the study even when the inotropic medication dose was lower. After registration of baseline values, dopamine was reduced to 2.5 micrograms/kg per min, and norepinephrine was administered starting at a dose rate of 0.05 micrograms/kg per min, until a MAP of greater than 60 torr could be maintained. RESULTS. Of the 26 patients investigated, 16 survived; 10 patients with persisting sepsis died due to multiple organ failure (mortality: 38.5%). During the study period, a norepinephrine dosage ranging between 0.1 and 2 micrograms/kg per min was necessary to stabilize the arterial pressure. The mean dose rate was 0.3 micrograms/kg per min. The mean arterial pressure and systemic vascular resistance index showed a statistically significant increase of 30 and 20%, respectively, just after 1 h and distinctly remained above the initial values in the further course. The cardiac index remained constant or increased slightly. After 24 h a statistically significant increase in stroke volume and a decrease in heart rate could be observed. Creatinine clearance increased significantly from the control value of 73 +/- 48 ml/min to 114 +/- 37 ml/min after 48 h under norepinephrine treatment. O2-delivery and O2-consumption did not change significantly, although they showed a slight tendency to increase. CONCLUSION. When patients are in a septic high output-low resistance condition, particular attention must be paid to maintaining sufficient mean arterial pressures. Our results suggest that this essential goal can be achieved by norepinephrine. The mean arterial pressure and glomerular filtration rate improved markedly, and there was no evidence of bad effects such as an increased afterload on critical parameters like cardiac index, O2-delivery and O2-consumption.

One hundred five patients receiving concurrent aminoglycoside and vancomycin therapy of at least 5 days' duration were retrospectively reviewed for development of nephrotoxicity. All had their vancomycin and aminoglycoside serum concentrations controlled by a clinical pharmacokinetics service. Nephrotoxicity occurred in 28 (27%) of the patients. Twenty-two of the 28 had other factors that are known to contribute to renal failure (amphotericin B therapy, sepsis, liver disease, obstructive uropathy, pancreatitis, anesthesia). The remaining six developed nephrotoxicity without other known contributing factors. Logistic regression analysis revealed associations between nephrotoxicity and age, sex, aminoglycoside trough and vancomycin peak and trough serum concentrations, length of aminoglycoside and vancomycin therapy, concurrent amphotericin B therapy, liver disease, neutropenia, and peritonitis (p less than 0.05). In addition to factors previously reported, this study found that neutropenia and peritonitis are associated with an increased risk of nephrotoxicity. Patients with one or more risk factors warrant close monitoring of renal function as well as vancomycin and aminoglycoside serum concentrations.

The complications presented by 36 patients submitted to anti-reflux procedures that were treated in our Hospital in a 10 year period, from September 1978 to May 1988, are analyzed. The patients were divided in 2 groups depending on the initial treatment being performed inside or outside our Hospital. The indication for the initial operation was reflux esophagitis in all patients, 4 or whom, had developed a shortened esophagus with stenosis. The selected procedures were of several types with a clear predilection for the Nissen type fundoplication with its variants. Different kinds of complications were observed; mortality was associated with gastric or esophageal leak, with a fatal outcome in 11 patients, another one died of postoperative pancreatitis and abdominal sepsis (33.3 percent mortality rate).

Endoscopic retrograde cholangiopancreatography and its therapeutic applications are the most invasive and risky procedures performed regularly by endoscopists. Potential complications include those of the endoscopy (sedation reactions, infection transmission, perforation, etc.), those specific to instrumentation of the bile duct and pancreas (sepsis, pancreatitis) and those caused by therapeutic intervention, especially sphincterotomy (perforation and bleeding). These complex procedures require two fully trained GI nurse assistants. One is responsible for the safety of the patient (who is often elderly and frail) before, during and after the procedure. The other is responsible for ensuring that all necessary equipment is available and correctly disinfected and assists the endoscopist during the examination.

The detection of TATC may inform about the presence of thrombin generation and, and hence of a pre-thrombotic status. An ELISA test (Enzygnst TAT) has been developed here in order to evaluate the predictive role played by TATC, and it was applied on 182 patients who distributed in 14 with cirrhosis of the liver, 11 with sepsis, 17 with chronic arterial insufficiency, 55 with neoplasms, 9 with thrombosis, 15 in postoperative period, 15 with pneumonia, 16 with disseminated intravascular coagulation (DIC), 14 with multiple injuries and 16 with pancreatitis. TATC levels were significantly increased in all groups with regard to the control group. Patients with thrombosis, sepsis, multiple injuries, DIC and in the postoperative period showed especially high TATC figures. No correlation between TATC and fibrinogen, platelet count, activated partial thromboplastin time or prothrombin complex assay was found in the post-operative patient-group. It was concluded that TATC are a good indicator of hypercoagulability.

Previous investigators suggested that increased plasma levels of the terminal complement complex (sC5b-9) are an early marker for the development of adult respiratory distress syndrome (ARDS) in septic patients. We asked whether an increase in sC5b-9 was also associated with the development of ARDS from other etiologies and whether sC5b-9 measurements consistently reflected complement activation in vivo. We evaluated 75 patients with sepsis, trauma, hypertransfusion, multiple fractures, aspiration, or pancreatitis who were at risk for ARDS but did not develop the syndrome and 23 patients with similar histories who did develop ARDS. Of the latter patients, seven were identified and studied both when they were at risk and when they had ARDS. Serial blood samples were obtained and analyzed for the complement activation products Bb, Ba, C4d, C3d, IC3b, and sC5b-9. All but one of the patients studied had levels of one or more complement fragments that were greater than 2 SD above the mean obtained from 18 normal subjects. In contrast to the report referred to previously, none of the fragments measured, including sC5b-9, was a specific indicator of ARDS, and no combination of complement fragments predicted which patients at risk would develop ARDS. Patients demonstrated evidence of activation of the classical pathway only, alternative pathway only, or both pathways, but none of these was associated with greater risk or severity of disease. In addition, in several patients only late components were activated, suggesting that enzymes other than those derived from complement activation may be responsible. In conclusion, complement can be activated by a variety of mechanisms in critically ill patients.(ABSTRACT TRUNCATED AT 250 WORDS)

We describe our experience between 1985 and 1989 with 24 patients with clinically significant pancreatitis after endoscopic retrograde cholangiopancreatography. The resulting pancreatitis was categorized into three groups, all requiring hospitalization: (1) mild pancreatitis (n = 12); (2) moderate pancreatitis requiring aggressive evaluation, treatment, and follow-up (n = 6); and (3) severe pancreatitis requiring surgical therapy (n = 6). The average length of hospitalization for the entire group was 12.8 days. Surgical intervention was required in 5 patients, and 3 patients died of acute necrotizing pancreatitis with sepsis, adult respiratory distress syndrome, and intractable hemodynamic failure. Our experience with this entity suggests that this form of pancreatitis includes severe and even lethal outcomes. It was associated with a mortality of 13%.

Radionuclide cholescintigraphy (RC) is a useful adjunctive diagnostic tool for the identification of acute cholecystitis. False-positive rates, that is, nonvisualization, of 10 to 38 per cent have been reported in patients with factors associated with nonfilling of the gallbladder, such as prolonged fasting and the administration of total parenteral nutrition, pancreatitis, alcoholism or other critical illnesses. The administration of morphine sulfate increases resting pressure of the common bile duct because of constriction of the sphincter of Oddi, and increases the likelihood of gallbladder visualization. We administered morphine sulfate (0.05 to 0.1 milligram per kilogram given intravenously) to 68 patients (including 25 critically ill patients) suspected of having biliary sepsis and who demonstrated nonvisualization of the gallbladder by RC at 30 to 60 minutes. Visualization of the gallbladder occurred within 60 minutes after the administration of morphine sulfate in 38 patients and within 30 minutes in 36 of the 38, aiding in exclusion of the diagnosis of acute cholecystitis in 37 patients. Acute cholecystitis was confirmed by laparotomy in 28 of the remaining 31 patients. There were two false-positive and one false-negative scans, yielding a sensitivity rate of 97 per cent, a specificity rate of 95 per cent, positive and negative predictive values of 0.93 and 0.97, and an accuracy of 96 per cent for this investigative procedure. We conclude that administration of morphine sulfate in conjunction with RC in seriously ill patients enhances the reliability of this test.

During the past two decades, cholelithiasis has been recognized in increasing numbers of pediatric patients. This diagnosis should be considered in the event of upper abdominal complaints, particularly when one or more risk factors are evident. The etiology may be unknown or may be related to risk factors, including hemolytic conditions. In recent years, it has become evident that approximately 80% of gallstones in children are not due to hemolytic disease and that the remaining 20% are related to recurring hemolysis. The diagnosis of gallstones is best confirmed with ultrasonography. Routine ultrasonographic evaluation should be performed at intervals for all children who received TPA for more than 4 weeks, particularly those who have had ileal resection or have had chronic enteritis (Crohn disease). Cholecystectomy is the procedure of choice for symptomatic children with cholelithiasis, regardless of age. Cholecystectomy is recommended for the asymptomatic child younger than 3 years of age when echogenic shadows have been present for at least 12 months following resumption of oral feedings or when the gallstones are radiopaque. Also, cholecystectomy is advised for asymptomatic children who are older than 3 years of age if ultrasonographic studies confirm that echogenic foci with shadowing are true stones and not echogenic sludge. Complications of common bile duct obstruction, pancreatitis, perforation with bile peritonitis, and life-threatening sepsis may thus be prevented. Morbidity and mortality following cholecystectomy are expected to be relatively low in the pediatric age group.
