To delineate the natural clinical course of spontaneous bacterial peritonitis in hepatitis B-related cirrhosis and to determine if it occurs in hepatocellular carcinoma, a prospective survey was conducted in 262 patients over 2 1/2 years. The in-hospital incidence and mortality rates of spontaneous bacterial peritonitis were 21.6% and 36.4%, respectively, in cirrhosis and 7.3% and 50% in hepatocellular carcinoma. In cirrhosis, the cumulative probability of annual recurrence of spontaneous bacterial peritonitis was 47.3%, which was significantly higher than the annual probability of occurrence of 11.3% in those with no previous attack (P less than 0.0001). The cumulative probability of annual survival was 27.6% in the spontaneous bacterial peritonitis patients, significantly lower than the probability of 64.0% in the control group (P = 0.0001). A univariate analysis, with Kaplan-Meier curves compared by the Mantel-Cox test, and subsequent multivariate analysis by stepwise Cox regression procedure were used to evaluate 37 variables recorded immediately after admission. Blood urea nitrogen concentration greater than 10.5 mmol/L urea (greater than 30 mg/dL) and ascitic fluid protein concentration less than 7.35 g/L (less than 735 mg/dL) were found to be the only significant predictors of lower annual survival; ascitic fluid protein concentration less than 7.50 g/L (less than 750 mg/dL) was the only significant predictor of higher annual recurrence. The authors conclude that spontaneous bacterial peritonitis has a high risk of recurrence in hepatitis B-related cirrhosis and that the same disease occurring in patients with hepatocellular carcinoma is related to the underlying cirrhosis rather than the hepatocellular carcinoma.

Chemical analysis of ascitic fluid may be helpful in determining the underlying disease. We discuss the diagnostic accuracy of the common and newer chemical parameters (protein, LDH, lactate, glucose, cholesterol, triglycerides, phospholipids, fibronectin, albumin gradient [value of serum minus value of ascites], ferritin, tumor markers, immunomodulators, leukocytes, bacterial and cytologic examinations). We also review the pathogenesis and clinical findings of the most frequent ascites forms (benign hepatic, infective, malignant ascites, ascites associated with liver metastases or hepatocellular carcinoma, cardiac and pancreatic ascites) and the most important diagnosis criteria. In the malignant ascites a high cholesterol, a narrow albumin gradient or a high ferritin value have high diagnostic accuracy, but diagnosis is by the finding of malignant cells. For the diagnosis of infective ascites, bacteriology is mandatory even though the results are negative in most cases, particularly in spontaneous bacterial peritonitis where diagnosis has to be established clinically, by a low pH or by a high leukocyte count. Benign hepatic ascites is diagnosed by demonstrating an underlying chronic liver disease and laboratory examinations of the peritoneal fluid to exclude other causes. The laboratory tests in ascites associated with liver metastases or with hepatocellular carcinoma were similar to those in benign hepatic ascites and the two ascites forms must be separated by other clinical and technical findings. Pancreatic ascites can easily be distinguished from the other forms by the high amylase and lipase content.

Critical considerations are expressed on scientific approach to liver cirrhosis, a nosological entity based on both analytical inquiry and long term observation of a large number of cirrhotic patients. The main points taken into consideration are: the etiopathogenesis of cirrhosis; a systematic of diagnostic elements; some preventional aspects of the disease and of its major sequelae. In the histogenetical analysis, the following steps are identified and analysed: a) hepatocellular death (necrosis), b) inflammatory process, c) fibrosis, d) hepatocellular regeneration and disorganized vascular architecture as a consequence of nodular regeneration. The hepatotoxic action of the three most studied and widespread etiologic agents of cirrhosis, alcohol, HBV, iron, is also considered. Finally, as a last pathogenetic step and peculiar to liver cirrhosis, the complex vascular rearrangement that leads to a relative increase of the liver blood flow is analysed. Clinical experience suggests a distinction between active and inactive liver cirrhosis. In the former we find a chronic active hepatitis associated with nodular regeneration and subsequent compensatory blood flow rearrangement. No signs of chronic active hepatitis can be found in the latter which is characterized by irreversible alteration of the liver architecture, reduction of the liver function and hemodynamic rearrangement (portal and arterial). Both nosologic entities can be either clinically characterized or not by symptoms of the major sequelae and complications of cirrhosis. On the basis of the clinical experience, among the complications of cirrhosis spontaneous bacterial peritonitis, gastrointestinal bleeding, hepatorenal syndrome and hepatocarcinoma appear to have a great prognostic value. Association between hepatocarcinoma and liver cirrhosis, which seems to be independent of single etiologic factors of cirrhosis itself, also has a great reliance.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to test the diagnostic value of ascitic fluid cholesterol and triglycerides concentrations and of serum-ascites albumin concentration gradient in the differentiation between cirrhotic and malignant ascites. These biological parameters were determined, on the one hand in 34 cirrhotic patients, 6 of them having an hepatocellular carcinoma and 6 others having a spontaneous bacterial peritonitis and, on the other hand, in 16 patients with malignant ascites, 13 of them having an abdominal extra-hepatic or pelvic cancer, and 3 others having an extra-abdominal cancer with multiple liver metastases. Ascitic carcinoembryonic antigen assay and ascitic fluid cytology were also done in the 50 patients. In differentiating the cirrhotic patients from those with malignancy, ascitic fluid cholesterol concentration (discriminating value less than 1.1 mmol/l) ascitic fluid triglycerides concentration (discriminating value 0.5 mmol/l) and serum-ascites albumin concentration gradient (discriminating value greater than 11 g/l) allowed a diagnostic efficiency of 0.92, 0.80 and 0.77, respectively. Ascitic fluid cytology showed presence of malignant cells in 3/6 patients with hepatocellular carcinoma associated with cirrhosis, in 9/16 patients having a malignant ascites, and was negative in other patients. Ascitic carcinoembryonic antigen assay was abnormal only in 3/16 patients with malignant ascites. These results suggest that measurement of ascitic fluid cholesterol concentration must be included in the initial evaluation of patients with ascites of unknown origin.

The aim of this study was to determine the efficacy of oral antibiotics in the treatment of severe infections in cirrhosis. Twenty-two patients (17 males, 5 females) with spontaneous bacteremia (n = 7) or bacterial peritonitis (n = 15) were treated with oral pefloxacin 400 mg per 24 hr alone (n = 1) or in combination with another oral antibiotic, trimethoprimsulfamethoxazole (n = 13), amoxicillin (n = 6), cefadroxil (n = 2), or metronidazole (n = 1). In patients with spontaneous bacteremia, all organisms were found to be sensitive to oral antibiotics, and a favorable response was elicited in 6 out of 7 (86 p. cent) within 3 days (mean) of treatment. In patients with spontaneous peritonitis, ascitic fluid cultures were positive in 11 cases, and organisms were sensitive to pefloxacin in 9 out of 11 cases. A favorable response was elicited in 13 out of 15 within 2 to 8 days of treatment. Fourteen patients died (64 p. cent), 3 of infection (bacteremia n = 1, peritonitis n = 2), and 11 patients of causes unrelated to infection, mainly variceal hemorrhage, hepatorenal syndrome or hepatocellular carcinoma, although the clinical symptoms of infection were controlled. One-year survival was 57 p. cent in patients with bacteremia and 33 p. cent in those with bacterial peritonitis. Oral treatment was well tolerated in all patients. We suggest that most bacteremia and spontaneous bacterial peritonitis in cirrhotic patients can be treated with oral antibiotics. In some patients, this may be accomplished on an out patient basis.

The aim of this retrospective study was to define prognostic factors for cure and survival after spontaneous bacterial peritonitis. In a 4-year period from 1982 to 1986, spontaneous bacterial peritonitis was diagnosed in 38 consecutive hospitalized cirrhotic patients (positive ascites culture and polymorphonuclear cell concentration greater than 250 cells per mm3). Twenty-five patients recovered from their infection (69 p. 100) in a mean time of 9 +/- 7 days. The cumulative survival was 68 p. 100 at one week, 50 p. 100 at one month, and 25 p. 100 at one year. The best independent prognostic factors for lack of cure from peritonitis were a low ascitic pH value (p less than 0.001), an elevated serum creatinine level (p = 0.01) and the presence of hepatocellular carcinoma (p less than 0.05). The best prognostic factors for death were low ascitic pH value (p = 0.001) and gastrointestinal hemorrhage (p = 0.005). A low ascitic pH value was correlated with other signs of severe infection (signs of generalized infection, ongoing infection during the first week after diagnosis), with signs of severe liver disease (encephalopathy, hepatocellular carcinoma) or severe renal dysfunction (high serum creatinine level, low arterial pH value). Because of the late high-death rate associated with spontaneous bacterial peritonitis, liver transplantation should be considered in these patients.

We studied fibronectin concentration in the ascitic fluid of 102 patients, 71 with cirrhosis, 13 with hepatocellular carcinoma, 12 with malignant peritonitis, and six with miscellaneous disease. Fibronectin concentrations in the first three groups were 45 +/- 45 mg/l, 54 +/- 84 mg/l, and 144 +/- 123 mg/l, respectively. The difference between patients with cirrhosis and malignant peritonitis was significant (p less than 0.01). However, fibronectin concentration greater than 100 mg/l had a sensitivity of 58 per cent and a specificity of 86 per cent for the diagnosis of malignant peritonitis. Ascitic fluid protein content over 30 g/l had the same sensitivity and specificity was 90 per cent. Among cirrhotic patients, high fibronectin concentrations were demonstrated in those with long-standing ascites (m = 134 +/- 58 mg/l) whereas the lowest concentrations were found in patients with severe hepatocellular failure (m = 12 +/- 9 mg/l). Concentrations were significantly different, according to whether or not spontaneous bacterial peritonitis occurred later (20 +/- 13 mg/l versus 52 +/- 49 mg/l); 83 per cent of patients with spontaneous bacterial peritonitis during their clinical course had initial fibronectin concentrations above 30 mg/l in their ascites. We conclude that: 1) measurement of fibronectin concentration in ascitic fluid is of poor diagnostic value for discrimination between malignant and non malignant ascitic, 2) low concentrations of fibronectin are associated with the occurrence of spontaneous bacterial peritonitis in cirrhotic patients. Hypothetically, the quantitative defect of fibronectin could be responsible for bacterial opsonization impairment in these patients.

To evaluate the diagnostic accuracy of fibronectin levels in ascites to differentiate malignant from non-malignant ascites, the authors studied 30 patients with sterile uncomplicated ascites in chronic liver disease, 18 patients with malignant ascites and four patients with spontaneous bacterial peritonitis. Fibronectin concentration was significantly higher in malignant ascites than in sterile ascites (P less than 0.001). High values (greater than 85 mg/l) were found in four of six cases of hepatocellular carcinoma in liver cirrhosis with negative cytologic examination, and in six of seven peritoneal carcinomatoses. Low values (less than 85 mg/l) were found in four patients with liver metastases and in one patient with intrahepatic biliary duct carcinoma in cirrhosis. In four patients with infected ascites, the fibronectin level was low. Among all other parameters (total protein concentration, lactate dehydrogenase, gamma-glutamyl-transpeptidase, pH, amylase, triglycerides, leukocyte count, and cytologic examination), fibronectin yielded the best degree of discrimination (diagnostic accuracy, 79%).

Between March 1982 and September 1983, 40 inpatients (25 men and 15 women, mean age 53 years) with alcoholic cirrhosis and total serum bilirubin greater than or equal to 5 mg per dl were studied. Those with hepatocellular carcinoma, renal failure, hyponatremia, septicemia, spontaneous bacterial peritonitis, gastrointestinal bleeding, and hepatic coma were excluded. Patients were studied for 28 days. The two groups were offered an oral diet containing 40 kcal per kg per day. Patients in the supplementary parenteral nutrition group received 40 kcal per kg per day and 200 mg nitrogen per kg per day using a central catheter. The major endpoint was total serum bilirubin on Day 28. On admission, serum bilirubin was not significantly different in the two groups: oral group, 12.5 +/- 6.6 mg per dl; supplementary parenteral nutrition group, 12.3 +/- 8.5 mg per dl. On Day 28, serum bilirubin was lower in the supplementary parenteral nutrition group (2.5 +/- 1.4 mg per dl) than in the oral group (4.1 +/- 2.2 mg per dl) (p less than 0.02). Serum bilirubin was also lower in the supplementary parenteral nutrition group than in the oral group on Days 7, 14 and 21 (p less than 0.05). Analysis of covariance, considering serum bilirubin on admission and at randomization and time between admission and randomization, confirmed these results. On Day 28, anthropometric parameters, serum transferrin, prealbumin and retinol-binding protein were higher in the supplementary parenteral nutrition group, but the differences were not significant. Serum albumin was significantly lower in the supplementary parenteral nutrition group. The incidence of encephalopathy and sepsis was not significantly different between the two groups.

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.
