During a two-year period, 30 patients with spontaneous bacterial peritonitis were documented. All patients had ascites and 70% were alcoholic cirrhosis. Fever and abdominal pain were the most frequent presenting manifestations (96.66% and 76.66% respectively). Triads of fever, abdominal pain and rebound tenderness were found in 40%. A third had hepatic encephalopathy and decreased bowel sound. Ascitic fluid was transudate. Positive ascitic fluid culture and blood culture were obtained in 40% and 59% respectively, and three quarters were due to gram negative enteric bacilli. There was no significant statistic correlation among the result of ascitic fluid gram's stain and ascitic fluid culture, and of ascitic fluid culture and blood culture. The clinical and laboratory findings of patients with positive and negative ascitic fluid culture were similar. Significant increased mortality was found in patients who had hepatic encephalopathy, hypotension, increased bilirubin level and serum creatinine. The over all mortality was 33.33%. We recommend abdominal paracentesis in every cirrhotic patients with ascites who were admitted into hospital.

We studied the functional effects of intraperitoneal sepsis on systemic hemodynamics in general, and on renal function in particular, in sheep in whom bacterial peritonitis was induced by cecal perforation. In the first group of seven sheep (group 1) fluid was administered throughout the period of sepsis to maintain pulmonary capillary wedge pressure as close to presepsis values as possible. These sheep exhibited hemodynamic changes known to be associated with sepsis in man: increased cardiac output and decreased systemic vascular resistance. In a second group of seven sheep (group 2) fluid intake was restricted; compared with group 1, these sheep demonstrated a smaller increase in cardiac output that did not persist and that was associated with an increase in the systemic vascular resistance during the septic period. Plasma renin levels increased fivefold in group 2 but were unchanged in group 1. Serial renal biopsies during the septic period revealed that all sheep had evidence of tubular cell damage on electron microscopy: cell swelling, loss of the microvillous brush border, and cell necrosis. Both groups of sheep also demonstrated marked tubular proteinuria similar to that found in humans with generalized sepsis. Despite this, sheep in group 1 exhibited no functional renal changes: creatinine clearance levels rose slightly from control values, urine concentrating ability was unimpaired, and fractional excretion of sodium increased appropriately in response to a sodium load. In contrast, group 2 sheep exhibited a fall in creatinine clearance levels but fractional sodium excretion did not fall as would have been expected were renal function entirely normal. The results suggest that generalized "hyperdynamic" sepsis induces tubular cell damage and tubular proteinuria by an unknown mechanism. However, this does not necessarily produce renal impairment since the glomerular filtration rate does not fall unless volume contraction is also allowed to occur.

Cefamandole in combination with tobramycin was evaluated in the treatment of peritonitis as an adjunct to laparotomy and performance of the indicated surgical procedure in 88 patients. The clinical response was judged satisfactory in 91 per cent. Of four deaths, only one could be attributed to infection. Side effects noted were decreased creatinine clearance in 16 patients, increased liver enzymes in ten patients, and eosinophilia in nine patients. Microbiologic studies revealed aerobic peritonitis in 44 cultures and anaerobic in 32. Eighty-five per cent of the gram-negative and 69 per cent of the gram-positive strains were susceptible to cefamandole. Cefamandole alone or in combination with tobramycin appears to be an effective and safe antibiotic when used in appropriate doses for the treatment of bacterial peritonitis.

Four children aged 6-10 years (body weight 20-31 kg) and one adolescent patient (age 17 years, 32 kg) were treated by continuous ambulatory peritoneal dialysis (CAPD) over periods of 4-14 months totalling 39 months. Dialysis volumes of 1 liter for the pediatric patients and 1.5 liters for the adolescent patient were exchanged four times daily: glucose concentration was 15 milligrams during three cycles and 42.5 milligrams during one cycle. Bag exchanges and general care of the younger patients were primarily carried out by their mothers. Overall rehabilitation and patients' acceptance were good despite several complications, but full school attendance was only achieved in 2 children. Uremia and fluid balance were well controlled despite minimal dietary restrictions. Average serum urea was 20 mmol/l and creatinine 700 mumol/l. Glucose reabsorption from dialysate was 1-4 g/kg per day. Bacterial peritonitis occurred six times and responded well to appropriate treatment. Its incidence decreased from one episode every 4-5 months (before July 1980) to one every 8 months. Protein losses in the dialysate were 0.10-0.17 g/kg per day in 4 children; the serum protein was 57-69 milligrams. One child with sterile peritonitis lost 0.46 g protein per kg per day and became frankly hypoproteinemic (47 micrograms). Technical problems included cuff erosion (3 cases), and dislocation (1) or malposition (1) of the Tenckhoff catheter. Statural growth was unsatisfactory in 2 children treated for more than 9 months. CAPD was terminated by cadaveric renal transplantation in 3 patients, and by recovery of renal function in one. One patient is still on CAPD. CAPD offers a valuable alternative to hemodialysis in selected pediatric patients. However, the choice between the two methods should be left to specialized child centers. The long-term potential of CAPD still remains to be defined.

Forty-three patients with spontaneous bacterial peritonitis (SBP) between 1973 and 1978 were identified. Criteria for SBP included a positive ascites culture and polymorphonuclear cell concentration greater than 250 cells per mm3. Chronic liver disease was documented by varices in 91%, severe histologic fibrosis or cirrhosis in 94%, splenomegaly in 91%, and past hospitalization for liver disease in 57% of the patients. SBP was detected within 7 days of admission in 17 patients (40%) and within 35 days in 38 patients. Single organisms were isolated from 38 patients and multiple organisms from 5 patients. Twenty-six of 43 patients survived the episode of SBP, but only 13 survived the hospitalization. Analysis of the survival curve from the onset of SBP revealed a rapid death rate and a slow death rate set of patients. Rapid death (less than or equal to 7 days from SBP onset) correlated with a lack of prior hospitalization for liver disease (p less than 0.001), hepatomegaly (p less than 0.001), increased serum bilirubin (p less than 0.005), serum creatinine (p less than 0.05), and peripheral white blood cell concentrations (p less than 0.05). Survival during hospitalization was associated with prior hospitalization with liver disease (p less than 0.001) and chills during the episode of SBP (p less than 0.001). The 43 patients were divided into Group 1 patients on the basis of a serum bilirubin greater than 8 mg% and/or serum creatinine greater than 2.1 mg%; Group 2 patients had lower values. Survival was greater in Group 2 patients with advanced, relatively quiescent liver disease compared to Group 1 patients for both the episode of SBP (91 vs. 29%; p less than 0.001) and for hospitalization (50 vs. 9%; p less than 0.05). Death in Group 2 patients was related to inadequate antibiotic therapy (p less than 0.05), nonhepatic factors, and new onset of renal failure. Although SBP in the setting of severe acute liver injury has a dismal prognosis, SBP with minimal acute liver injury has a relatively good prognosis for hospital survival even with advanced chronic liver disease. Long-term survival is also possible since 4 of 9 patients with prolonged follow-up have survived 3 years.

To determine the potential role of orthotopic liver transplantation (OLT) in cirrhotic patients surviving a first episode of spontaneous bacterial peritonitis (SBP), medical records of 79 patients presenting with a first episode of SBP were reviewed. Of these patients, 37 were selected as potential candidates for OLT using the following criteria: absence of hepatocellular carcinoma; no severe organ failure other than the liver; age < or = 66 years; and survival after SBP > 60 days. Survival time was calculated from the day of SBP diagnosis. Prognostic value of clinical, biological and bacteriological data recorded at the time of SBP was determined using univariate and multivariate analysis (Cox's regression model). Survival rate of the potential candidates for OLT at 3 months, 1 year and 2 years was 94, 46 and 30% respectively. Serum creatinine value (P = 0.001) and Pugh score (P = 0.005) were independently correlated with death. The 1 year survival rate was 80% for the 11 patients with a Pugh score < 10, and 26% for the 26 patients with a Pugh score > or = 10. Our results suggest that after SBP, OLT should be considered in patients with severe liver disease. Survival of patients with a moderate liver disease (i.e. Pugh score < 10) might be relatively high.

In order to identify the predictive factors of hospital mortality in cirrhotics with spontaneous bacterial peritonitis (SBP), we studied 64 patients who fulfilled the accepted diagnostic criteria. All cases were treated with cefotaxime up to 2 days after the infection was considered cured (7.7 +/- 2.9 days). Eleven patients (17%) died while in hospital, six of them before SBP was cured. After uni- and multivariate analyses, only seven routine clinical, biological, and bacteriological variables studied were independently associated with hospital mortality. These were: the presence of upper gastrointestinal bleeding at admission (beta = 2.01), the absence of abdominal pain as presenting symptom (beta = -1.29), the polymorphonuclear count (%) in the ascites (beta = 0.48), prothrombin rate (beta = -0.22), and serum Na (beta = -0.64), creatinine (beta = 0.50), and cholesterol (beta = -0.68). When the equation obtained was computed in a randomly selected sample of the patients studied, it correctly predicted the outcome in 92.3% of the cases. We conclude that short-term outcome of SBP patients depends on the existence of recent gastrointestinal bleeding, the severity of SBP, and the degree of liver and renal failure. The prognostic value of this model needs prospective validation in a new series of patients.

We made a retrospective study of 233 episodes of spontaneous bacterial peritonitis that were treated at our Service between January 1980 and September 1996 in order to analyze the clinical presentation, microbiological data, possible pathogenic factors, treatment, and evolution of this clinical entity. Ascites, abdominal pain, and fever were the most frequent symptoms. Only 3.43% of the episodes developed asymptomatically. Thirty-six episodes resulted in the patient's death (15.45%) and, of all the factors analyzed, only a prothrombin time of < 35%, bilirubin > 8 mg/dl, and serum creatinine > 2.1 mg/dl were statistically correlated with a higher death rate. The culture of the ascitic fluid gave a positive result in 47.6% of the cases, whereas no clinical differences were noticed between these patients and those with negative results. The most frequently isolated microorganisms turned out to be Gram negative (49.54%). A proportion of 71.24% of the episodes were treated with cephotaxime (i.v.), whereas 28.76% were treated with other drugs or pharmacological combinations. The death rate was much lower with cephotaxime (4.81% vs. 41.79%, p < 0.01%).

Spontaneous bacterial peritonitis (SBP) is associated with an important production of inflammatory mediators. However, it is unknown whether there is a relationship between the abdominal production of these mediators and the development of renal impairment, one of the most important prognostic parameters in spontaneous bacterial peritonitis. We studied 52 cirrhotic patients at diagnosis and resolution of the infection, by measuring endotoxin, tumor necrosis factor (TNF), and interleukin-6 (IL-6) levels in plasma and ascitic fluid. Thirteen patients (25%) developed renal impairment. Patients developing renal impairment showed significantly higher plasma and ascitic fluid cytokine levels at diagnosis of infection than patients who did not (plasma TNF-alpha: 96.0+/-38.7 vs. 39.1+/-3.6 pg/mL, P=.0209; ascitic fluid TNF-alpha: 474.5+/-118.1 vs. 160.8+/-42.7 pg/mL, P=.0173; plasma IL-6: 6,635+/-2,897 vs. 458+/-109 pg/mL, P=.0004; ascitic fluid IL-6: 182,559+/-47,328 vs. 39,250+/-10,803 pg/mL, P=.0001). Independent predictors of development of renal impairment at diagnosis were: renal failure (blood urea nitrogen > 30 mg/dL or serum creatinine > 1.5 mg/dL) (P < .001), IL-6 levels in ascitic fluid (P < .001), and mean arterial pressure (P < .05). Ten of the 13 (77%) patients who developed renal impairment died during hospitalization, but only 2 of the 39 (5%) patients who did not (P=.0001). In addition, renal failure at diagnosis of the infection was the only independent predictor of hospital mortality (P < .001). In conclusion, the inflammatory response to the infection may be an important mechanism of renal impairment and the associated mortality in SBP.

Cirrhosis of the liver results from a variety of mechanisms that cause progressive hepatic injury. It is the sixth leading cause of death in all patients between the ages of 35 and 55. This study attempts to correlate the morbidity and mortality of spontaneous bacterial peritonitis in liver failure patients to numerous etiologic and clinical variables. A retrospective review of 26 patients with spontaneous bacterial peritonitis associated with chronic liver disease was performed in a university hospital. Demographics (age and gender), clinical variables (etiology of liver failure, Child's classification, prior history of ascites, fever, abdominal pain, encephalopathy, and upper gastrointestinal hemorrhage), and laboratory variables (ascitic polymorphonuclearcyte count and cultures, serum albumin, bilirubin, creatinine, and prothrombin time) were studied. All of the patients had Child's C liver disease. Mortality rate was 46 per cent. Alcohol (46%) and hepatitis (30%) were the most common etiologies. Escherichia coli and Klebsiella pneumoniae were the most common culture isolates. All of the infections were monomicrobial. The only significant predictor of mortality (P < 0.05) in this study was the peritoneal fluid polymorphonuclear (PMN) cell count. PMN count >1000 PMN/mm3 was associated with a mortality of 88 per cent. Few patients with spontaneous bacterial peritonitis are ultimately transplanted.
