Spontaneous bacterial peritonitis is one of the most common complications of ascitic fluid in patients with liver cirrhosis. The aim of this study was to investigate the role of total protein, albumin, globulin and complement ascitic fluid concentrations in development of spontaneous bacterial peritonitis in patients with liver cirrhosis. In patients with liver cirrhosis and spontaneous bacterial peritonitis (n = 8) the ascitic fluid total protein, albumin and globulin concentrations were significantly lower than in patients with sterile ascites (n = 11) (p < 0.01). The ascitic fluid complement C3 and C4 concentrations were significantly lower in patients with spontaneous bacterial peritonitis than in patients with sterile ascites (9.1 +/- 3.1 mg/dL to 22.9 +/- 17.4 mg/dL, p < 0.01; 3.8 +/- 5.9 mg/dL to 8.2 +/- 5.9 mg/dL, p < 0.01, respectively). The ascites total protein, albumin, globulin and complement concentrations in cirrhotic patients with spontaneous bacterial peritonitis were significantly lower than in patients with sterile ascites demonstrating the importance of those factors in ascitic fluid defense against secondary bacterial infection.

The pathways and physiology of lymph absorption (LA) from the peritoneal cavity are well documented; however, much uncertainty still exists as to the various clinical and demographic factors affecting LA. We studied LA measured by the albumin instillation method, in adult Chinese CAPD patients, and showed that it was independent of age, sex, body surface area, duration of dialysis, intrinsic renal disease, use of intraperitoneal drugs (heparin/antibiotics/deferroxamine) and frequency of past bacterial peritonitis. High lymph absorbers had a relatively higher transcapillary cumulative ultrafiltration than low lymph absorbers. An enhanced LA was associated with a high initial intraperitoneal volume. Assessment of diaphragmatic strength by the decrement in vital capacity on changing from an erect to a supine position failed to distinguish patients with high and low LA.

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.

Tuberculous peritonitis is a rare disease, which often goes unrecognized because of the subtle clinical clues and its insidous onset. We retrospectively analyzed the records of 37 cases of tuberculous peritonitis diagnosed over a 15-year period, and compared the clinical and diagnostic features of cirrhotic and noncirrhotic patients. In cirrhotic patients, tuberculous peritonitis can simulate ascites from liver disease or spontaneous bacterial peritonitis. The diagnosis is difficult in these patients because the ascitic fluid may not be of the exudative type as a result of the low albumin level in serum, and lymphocytes do not predominate in all cases. Adenosine deaminase (ADA) activity in ascitic fluid was elevated (higher than 40 U/L) in all 11 patients (four patients with hepatic cirrhosis). The time required to achieve a correct diagnosis was significantly longer in cirrhotic than in noncirrhotic patients. The overall mortality was 13%, with deaths occurring exclusively among cirrhotic patients. We emphasize that tuberculous peritonitis in cirrhotic patients can present an atypical picture. A considerable element of suspicion is necessary.

The analysis of ascitic fluid has been complicated by several recently reported new tests. To simplify this assessment, we evaluated nine parameters prospectively and simultaneously in blood and ascitic fluid from 285 patients with ascites to determine which were the most reliable for immediate diagnosis of the etiology of the ascites and of its complications. Subjects were first divided into four groups: sterile cirrhotic ascites (n = 201), spontaneous bacterial peritonitis (n = 41), malignant ascites (n = 34), and miscellaneous ascites (n = 9). An ascitic fluid polymorphonuclear count greater than 500/microliters was the test with the greatest accuracy (96%) for the diagnosis of spontaneous bacterial peritonitis. Neither the most precise cutoff values for ascitic fluid pH (less than 7.32) and ascitic fluid lactate (greater than 32 mg/dl), nor their respective blood-ascitic fluid gradients (greater than 0.11 and less than -20 mg/dl) were more reliable indexes of spontaneous bacterial peritonitis, mainly due to the decreased ascitic fluid pH and increased ascitic fluid lactate observed in malignant ascites, tuberculous peritonitis, and pancreatic ascites. A blood-ascitic fluid albumin gradient less than 1.1 g/dl was the most accurate parameter for the diagnosis of malignant ascites (diagnostic efficacy, 93%). Therefore, the etiologic analysis of ascitic fluid might be simplified and the single practice of two tests, ascitic fluid polymorphonuclear cell count and blood-ascitic fluid albumin gradient, provides immediately useful information.

Repeated large-volume paracentesis (4-6 L/day) is an effective and safe therapy of ascites in patients with cirrhosis provided albumin is infused intravenously. To investigate whether ascites can be safely mobilized in only one paracentesis session ("total paracentesis"), 38 cirrhotic patients with tense ascites were treated with total paracentesis plus intravenous albumin (6-8 g/L ascites removed). Standard liver tests and renal function tests, glomerular filtration rate, free water clearance, plasma volume, plasma renin activity, and plasma aldosterone and norepinephrine concentrations were measured before and after treatment. Total paracentesis was effective in mobilizing ascites in all but 1 patient and did not impair any of the parameters studied. The volume of ascitic fluid removed and the duration of the procedure were 10.7 +/- 0.5 L (mean +/- SEM) and 60 +/- 3 min, respectively. Five of the 38 patients (13%) developed complications during the first hospital stay (hepatic encephalopathy and gastrointestinal hemorrhage in 2 patients each and culture-negative bacterial peritonitis in 1). No patient developed renal impairment. This complication rate, as well as the clinical course of the disease during follow-up, estimated by the probability of readmission to hospital, causes of readmission, and survival probability after treatment, was similar to that reported in patients treated with repeated large-volume paracentesis. These results indicate that total paracentesis associated with intravenous albumin can be safely performed in cirrhotic patients with tense ascites and suggest that these patients could be treated in a single-day hospitalization regime.

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.

Diagnostic paracentesis with ascitic fluid analysis is critical to the accurate diagnosis and management of ascites. Recent advances have improved the evaluation of ascitic fluid, among them the serum-ascites albumin difference for discriminating between ascites caused by liver disease and ascites due to malignancy. The ascitic fluid polymorphonuclear leukocyte concentration is the best index for the rapid presumptive diagnosis of spontaneous bacterial peritonitis. Familiarity on the part of the clinician with ascitic fluid interpretation and with ascitic fluid characteristics in various diseases will increase the chances of controlling ascites early.

We studied the effects of systemic sepsis on peripheral microcirculatory fluid exchange by examining changes in flow (Qlymph) and lymph-to-plasma [L/P] total protein and albumin ratios from lymph draining, the efferent duct of a prefemoral lymph node in sheep, before and during surgically-induced peritonitis. After baseline study, peritonitis was produced by cecal ligation, perforation, and devascularization. By 24 hours blood cultures revealed a polymicrobial bacteremia. The hemodynamic response to the septic insult during the 72-hour study period was characterized by an increase in heart rate and an initial fall in stroke volume index; yet, the mean blood pressure remained unchanged from baseline levels throughout the study protocol. The intrapulmonary shunt fraction increased (p less than 0.05) by 48 hours, as did both the Qlymph (2.6 +/- 1.9 ml/hr to 6.8 +/- 4.6 ml/hr; p less than 0.05) and the calculated lymph albumin clearance (1.6 +/- 1.2 ml/hr to 3.1 +/- 1.7 ml/hr; p less than 0.05). Although the calculated serum to interstitial colloid osmotic pressure gradient fell (F = 4.37; p less than 0.04), both the [L/P] total protein and albumin ratios were unchanged from baseline throughout 72 hours of study. Further, [L/P] total protein ratios were unrelated to Qlymph (r = -0.20); as Qlymph (experimental/baseline) increased with sepsis, [L/P] total protein ratio (experimental/baseline) did not fall (r = +0.62). We therefore conclude that systemic sepsis, as represented by this model of bacterial peritonitis, results in increased peripheral microcirculatory fluid flux that is primarily a consequence of an increase in permeability of the peripheral microvascular exchanging membrane.

One hundred sixty-five patients with cirrhosis diagnosed by needle liver biopsy were followed for 2 years to evaluate the relation between clotting factors and survival. Patients with spontaneous bacterial peritonitis, hepatic carcinoma, and cholestatic liver diseases were excluded. Patients were classified as A (n = 34), B (n = 75), or C (n = 56) according to Child-Pugh criteria. During the follow-up 45 patients died of liver failure or gastrointestinal hemorrhage. Nonsurvivor patients had significantly higher values of bilirubin and D-dimer, a marker of fibrinolysis in vivo, lower values of albumin, prothrombin activity, fibrinogen, prekallikrein, factor VII, and a more prolonged activated partial thromboplastin time than survivors. All these variables and Child-Pugh classification were significantly associated with survival in a univariate analysis. Multivariate analysis (Cox's model) showed that only prekallikrein and factor VII were independently predictors of survival. Ninety-three percent of patients with prekallikrein values < 32% died within 32 months of follow-up, whereas factor VII < 34% identified 93% of patients who died within 10 months of follow-up. This study suggests that factor VII is an early predictor of survival and may be a useful test to better identify cirrhotic patients who should be candidates for liver transplantation.
