Acute causes and chronic risk factors for the development of acute renal failure were analyzed in prospective acquired data of 261 patients in a medical ICU. The population was divided into a group requiring dialysis treatment for established renal failure (n = 95) and a collective maintaining mild renal insufficiency (n = 166). Bivariate and linear discriminant analyses revealed that, above all, variables related to bacterial infections (sepsis and administration of antibiotic agents) and pancreatitis contributed to the discrimination, followed by bleeding, volume depletion, and chronic liver disease in the discriminant function. Bivariate analysis also yielded significant results for mechanical ventilation, CNS depression, and surgery. The importance of the nephrotoxic properties of aminoglycosides may be outweighed by their role as an indicator of severe infectious disease. The overall correct classification rate of the discriminant function was 78.5%, which reflects the importance of the predictor variables, but does not allow individual predictions.

A retrospective review of 61 patients with calculous cholangitis was carried out. There were 31 men and 30 women and their mean age was 75.8 years. All patients had abdominal pain, 87% had chills and fever, 65% had clinical jaundice, 23% were in shock, and 54% had positive blood cultures. Because intravenous hydration and antibiotics did not help, 33 patients underwent surgery, 25 patients underwent endoscopic papillotomy (EP), and three patients underwent percutaneous transhepatic drainage of the common bile duct (PTD). Morbidity in the surgery group included two wound infections, one respiratory failure, and one renal failure. Morbidity in the EP-PTD group was one case of arterial bleeding requiring surgery and one of pancreatitis treated conservatively. Two patients (6%) died in the surgery group, one of sepsis and the other of cardiorespiratory arrest. In the EP-PTD group nine patients (32%) died of sepsis and multisystem organ failure. These patients were considered too ill to undergo surgery and thus repeat EP-PTD was carried out. Cholangitis persisted, and retained common bile duct stones with sepsis was the cause of death. Thus when initial EP or PTD is unsuccessful, surgical exploration of the common bile duct should be carried out to control sepsis.

To compare the effectiveness of cystgastrostomy and cystjejunostomy for treatment of pancreatic pseudocysts, 39 patients with cystgastrostomy were compared to 59 patients with cystjejunostomy. The groups were comparable in age, sex, cause of pancreatitis, pseudocyst location, symptoms, and preoperative serum amylase level. Cysts treated with cystgastrostomy were larger (mean diameter, 11.1 +/- 0.9 cm) than cysts treated by cystjejunostomy (mean diameter, 6.7 +/- 0.7 cm) (p less than 0.05). Mean duration of surgery was 148 +/- 11 minutes for cystgastrostomy versus 265 +/- 15 minutes for cystjejunostomy (p less than 0.05). Mean blood loss was 397 +/- 82 ml for cystgastrostomy versus 703 +/- 80 ml for cystjejunostomy (p less than 0.05) Mean intraoperative fluid requirements were 2640 +/- 313 ml for cystgastrostomy and 4403 +/- 362 ml for cystjejunostomy (p less than 0.05). Cyst recurrence was 10% for cystgastrostomy versus 7% for cystgastrostomy. Postoperative gastrointestinal bleeding occurred in 8% of patients with cystgastrostomy and in 2% of patients with cystjejunostomy. Infection problems with cystjejunostomy included two wound infections and one case of septicemia; infection problems with cystjejunostomy included five intraabdominal abscesses, two wound infections, and one case of pneumonia. Two patients died with cystgastrostomy (both from gastrointestinal bleeding); two patients died with cystjejunostomy (one from intraabdominal sepsis and one from pulmonary embolus). Cystgastrostomy was used for significantly larger pseudocysts and was associated with significantly less blood loss and operating time than cystjejunostomy (p less than 0.05). Morbidity and mortality from cystgastrostomy and cystjejunostomy were comparable, although gastrointestinal bleeding was more common with cystgastrostomy and intraabdominal abscess was more common with cystjejunostomy. Since cystgastrostomy can usually be performed more quickly and with less blood loss, it should be considered whenever anatomically feasible.

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)
