Ascitic fluid pH in alcoholic cirrhosis: a reevaluation of its use in the diagnosis of spontaneous bacterial peritonitis.

An ascitic fluid pH less than or equal to 7.31 has been advanced as being the best index in the early diagnosis of spontaneous bacterial peritonitis in cirrhotic patients. In order to test the validity of this criteria, 55 patients with alcoholic cirrhosis and ascites were studied. In each patient, arterial blood and ascitic fluid samples were analysed for pH, PCO2, total CO2 and PO2, and the pH gradient between blood and ascites was calculated. White blood cell and polymorphonuclear cell counts were determined in ascitic fluid, and cultures of ascites were done under aerobic and anaerobic conditions. Twelve patients had a culture proven spontaneous bacterial peritonitis. Their mean ascitic fluid pH (+/- SD) was 7.38 +/- 0.09 (range 7.21-7.49) and differed significantly (p less than 0.05) from that found in patients without spontaneous bacterial peritonitis: 7.44 +/- 0.06 (range 7.34-7.6.3). A marked overlap was observed, however, between the two groups, and only three out of the 12 patients with spontaneous bacterial peritonitis had an ascitic fluid pH less than or equal to 7.31. The pH gradient was 0.10 +/- 0.08 (range -0.01 to +0.28) in the spontaneous bacterial peritonitis group, as compared with 0.02 +/- 0.04 (range -0.09 to +0.12) in the sterile group (p less than 0.01), but a marked overlap was also noted between the two groups. In the spontaneous bacterial peritonitis group, the polymorphonuclear count was 3588 +/- 3849/microliter (range 60-11 776) versus 41 +/- 138/microliter (range 0-813) in the sterile group (p less than 0.0001). All but one patient in the spontaneous bacterial peritonitis group and only two patients in the sterile group had over 250 polymorphonuclear/ microliter. Thus, in our experience, neither the ascitic fluid pH nor the pH gradient values accurately discriminated the individual patients with and without spontaneous bacterial peritonitis. A polymorphonuclear count less than 250/ microliter remained the best criteria for the diagnosis of spontaneous bacterial peritonitis in cirrhotic patients, before having the results of ascitic fluid cultures.

Splanchnic and systemic hemodynamics in cirrhotic patients with refractory ascites. Effect of peritoneovenous shunting.

The splanchnic and systemic hemodynamics of 14 patients with refractory ascites were studied and were compared to those of 15 patients with ascites responding to medical treatment. Among the 14 patients, 10 were grade B and 4 C, according to the Pugh classification. Of the 15 patients, 5 were Pugh B and 10 C. In patients with refractory ascites, free hepatic venous pressure was significantly higher and hepatic venous pressure gradient was significantly lower than in patients with responsive ascites. Hepatic and azygos blood flows were not significantly different between the two groups. Cardiac output was lower in patients with refractory ascites (p less than 0.05) than in those with responsive ascites. In patients with refractory ascites, six months after peritoneovenous shunting, there was a significant reduction of wedged and free hepatic venous pressures and azygos blood flow. Cardiac output increased by 20 % (p less than 0.02). This study shows that hemodynamic alterations in patients with refractory ascites is the consequence of increased intraabdominal pressure due to chronic ascites. Six months after peritoneovenous shunting splanchnic and systemic hemodynamics became similar to those observed in patients without ascites.

Albendazole: a potent inhibitor of vascular endothelial growth factor and malignant ascites formation in OVCAR-3 tumor-bearing nude mice.

PURPOSE: Angiogenesis and vessel hyperpermeability are the two factors leading to the formation of ascites. Vascular endothelial growth factor (VEGF) plays a pivotal role in malignant ascites formation. We have recently shown that albendazole inhibits peritoneal growth of human colorectal cancer cells (HT-29). The present study was designed to find out if albendazole can suppress ascites formation in ascites-producing peritoneal carcinomatosis. EXPERIMENTAL DESIGN: Female nude mice bearing peritoneal tumors of human ovarian cancer cells (OVCAR-3) were treated with albendazole. Following i.p. inoculation and ascites development, mice were given i.p. albendazole (150 mg/kg) or the vehicle x 3 weekly for 4 weeks. RESULTS: Whereas vehicle-treated mice developed overt ascites requiring repeated aspiration, ascites formation in the albendazole-treated mice was markedly suppressed. As a result of this, 7 of 10 mice from the control group had to be euthanized before the course of treatment was over. Suppressed ascites production and reduced tumor vascularity observed was a result of dramatic reduction in tumor VEGF production as revealed by profoundly lower VEGF ascites fluid and plasma levels. In vitro, incubation of SKOV-3 cells with various concentrations of albendazole led to significant dose-dependent inhibition of VEGF secretion. Examination of floating tumor cells collected from the peritoneal wash revealed profound down-regulation of VEGF mRNA in albendazole-treated mice. CONCLUSIONS: These findings suggest for the first time that in nude mice bearing OVCAR-3 peritoneal tumors, by inhibiting VEGF production, albendazole abolishes tumor angiogenesis and ascites formation.

Targeting vascular endothelial growth factor blockade: ascites and pleural effusion formation.

PRIMARY PURPOSE: Formation of ascites and pleural effusion (PE) is a common problem for patients with advanced-stage cancer. These fluid accumulations cause severe symptoms such as abdominal distention, shortness of breath, cachexia, anorexia, and fatigue. Preclinical models have demonstrated that vascular endothelial growth factor (VEGF) plays a pivotal role in the accumulation of malignant PE or ascites. This study investigated whether blockade of VEGF activity would reduce biological activity of PE and ascites on endothelial cells of cancer patients. PATIENTS AND METHODS: The activity of VEGF in PE and ascites of 58 patients (39 with PE and 19 with ascites) was measured. An endothelial cell proliferation assay with human umbilical vein endothelial cells was used to determine the biological activity of ascites and PE. RESULTS: VEGF concentrations ranged from 67-6,245 pg/ml. A significantly higher concentration of VEGF was detected in the ascites and PE of patients with cancer (median, 1,290 pg/ml) than in patients with nonmalignant disease (median, 250 pg/ml; p = 0.02). Of the 58 PE and ascites samples, 41 were biologically active, based on a two- to fourfold stimulation of endothelial cell proliferation in 72 hours. VEGF concentrations were significantly higher in the biologically active samples compared with the 17 nonactive samples (2,056 pg/ml versus 771 pg/ml; p = 0.02). Coincubation of the samples with either a neutralizing polyclonal antibody against VEGF or SU5416, a small molecule inhibitor of the VEGF receptor Flk-1/KDR, inhibited endothelial cell proliferation by 66% and 100%, respectively. The inhibition caused by the antibody and that caused by SU5416 correlated significantly (r = 0.8, p<0.001). CONCLUSION: We conclude that malignant ascites and PE contain high levels of biologically active VEGF. This study strongly supports the hypothesis that blockade of VEGF, such as that afforded by SU5416, may benefit cancer patients with recurrent ascites or PE formation.

Clinical studies of hepatocellular carcinoma with liver cirrhosis and ascites.

A comparison was made of the clinical findings of 59 patients with liver cirrhosis (LC) accompanied with hepatocellular carcinoma (HCC) (of which 35 had ascites and 24 did not at the time of admission) and 164 patients with LC, but without HCC (of which 39 had ascites and 125 did not). HCC patients were older and more often had hepatomegaly, vascular spider and pleural effusion than LC patients. Ascites was more frequently observed in HCC than in LC patients when the serum albumin level and the indocyanine green disappearance rate were relatively well maintained and when peripheral edema was absent. There was no difference in the ascitic protein concentration between LC and HCC patients. Malignant cells were detected in ascites only in 14% of the HCC patients. These facts indicate the presence of ascites-inducing factors in HCC patients which have no direct relation to serum colloid osmotic pressure and effective hepatic blood flow. Almost all of the HCC patients with ascites (96%) died with ascites, whereas 54% of the LC patients with ascites recovered from the ascitic condition.

Leptin levels in the differential diagnosis between benign and malignant ascites.

AIM: To evaluate the role of leptin levels in the differential diagnosis of ascites. METHODS: Ascitic leptin, TNFalpha and serum leptin levels were measured in 77 patients with ascites (35 with malignancies, 30 cirrhosis and 12 tuberculosis). Control serum samples were obtained from 20 healthy subjects. Leptin and TNFalpha levels were measured by ELISA. Body mass index (BMI) and percentage of body fat (BFM) by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients. RESULTS: In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFalpha levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls. CONCLUSION: In patients with malignant ascites, levels of leptin and TNFalpha were significantly lower than in patients with tuberculous ascites.

Effect of tense ascites on esophageal body motility and lower esophageal sphincter pressure.

BACKGROUND: Esophageal motility and lower esophageal sphincter (LES) pressure change with rapid changes in intraabdominal pressure (IAP); the response of these to slow change in IAP is not known. AIMS: To study esophageal body motility and LES pressures in patients with cirrhosis with tense ascites in the basal state and after paracentesis. METHODS: Twenty four patients with cirrhosis of liver and tense ascites and 13 with cirrhosis without ascites (controls) were studied. Basal intragastric (IGP) and LES pressures, and esophageal body response to water swallows, were recorded using a water perfusion system; IAP was measured in patients with ascites. In patients with ascites, the study was repeated twice: after paracentesis of two liters of fluid and after adequate control of ascites. RESULTS: Basal IGP (p = 0.002) and duration of esophageal contraction (p = 0.01) were lower in controls, but basal LES pressures were similar in the two groups. After control of ascites, IAP (p = 0.02) and IGP (p = 0.005) decreased; amplitude and duration of distal esophageal contraction decreased (p < 0.05). The frequency of high-amplitude waves also decreased (p = 0.04). LES pressure remained unaltered. CONCLUSIONS: Esophageal contraction duration is increased in the presence of ascites, and decreases after control of ascites; LES pressure is not affected by ascites.

The value of ascitic fluid polymorphonuclear cell count determination during therapy of spontaneous bacterial peritonitis in patients with liver cirrhosis.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis is one of the most common complications attending the onset of ascites in patients with liver cirrhosis. The aim of this study was to demonstrate whether it is possible, on the basis of ascitic fluid polymorphonuclear cell count in patients with liver cirrhosis and spontaneous bacterial peritonitis, to determine the optimal duration of cefotaxime therapy, as the most frequently applied empirical therapy, and possibly anticipate the disease recurrence. METHODOLOGY: In 16 patients with alcoholic liver cirrhosis and confirmed diagnosis of spontaneous bacterial peritonitis, cefotaxime therapy was administered 2g t.i.d. during 5 days. Before the therapy, at 48 hours, 5 days and 15-20 days after the cefotaxime therapy was started, in all patients with spontaneous bacterial peritonitis diagnostic abdominal paracentesis was performed, each time determining the ascitic fluid polymorphonuclear cell count together with microbiological analysis. RESULTS: In the course of the "primary" spontaneous bacterial peritonitis attack, 3 patients died (18.8%). In 4 patients the recurrence of spontaneous bacterial peritonitis was observed within 15-20 days after therapy was discontinued. Two patients died during the therapy of spontaneous bacterial peritonitis recurrence. After 48 hours of therapy, 11 patients with the "primary" spontaneous bacterial peritonitis attack were without any symptoms (68.8%). Out of these 11, 10 patients (62.5%) had the ascitic fluid polymorphonuclear cell count lower than 250/mm3. After 5 days of therapy, 12 patients (75%) were free of symptoms, and the number of ascitic fluid polymorphonuclear cell count < 250/mm3 was still found in 10 (62.5%) patients. No association between the presence of symptoms 48 hours after the therapy and the recurrence of spontaneous bacterial peritonitis was established. A significant association was found between the ascitic fluid polymorphonuclear cell count determined 48 hours after the therapy and the recurrence of spontaneous bacterial peritonitis. A recurrence occurred in only 1 patient with the number of ascitic fluid polymorphonuclear cell count < 250/mm3, 48 hours after the therapy was started. A recurrence of spontaneous bacterial peritonitis occurred in all the patients who had an ascitic fluid PMN cell count > or = 250/mm3, 48 hours after the therapy was started. CONCLUSIONS: By monitoring the ascitic fluid PMN cell count it seems to be possible to determine the efficacy and optimal duration of cefotaxime therapy in patients with spontaneous bacterial peritonitis when it is of most importance that the number of ascitic fluid PMN cell count should decrease below 250/mm3 during the therapy.

Serum and ascites levels of macrophage migration inhibitory factor, TNF-alpha and IL-6 in patients with chronic virus hepatitis B and hepatitis cirrhosis.

OBJECTIVE: To study the potential role of macrophage migration inhibitory factor (MIF), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in the development of chronic virus hepatitis B (CH) and hepatitis cirrhosis (HC). METHODS: The serum concentrations of MIF, TNF-alpha and IL-6 in 18 patients with chronic virus hepatitis B and in 14 patients with hepatitis cirrhosis without ascitic fluid, and the serum and ascites cytokine concentrations in 22 HC patients with ascitic fluid were detected by enzyme linked immunity sorbed assay. RESULTS: The cytokine concentrations of the patients were significantly higher than those of the controls. The serum levels of MIF, TNF-alpha and IL-6 of the 22 patients with ascitic fluid were higher than those of 14 HC patients without ascites. In the 18 patients with CH, the serum cytokine concentrations were the lowest. The serum cytokine concentrations of the 22 HC patients with ascites were significantly higher than those of the 14 HC patients without ascites (P<0.01). Their serum cytokine concentrations were significantly higher than those in the 18 patients with CH (P<0.01). The concentration of IL-6 in ascites was the highest among all the groups. The serum levels of MIF, TNF-alpha and IL-6 are correlated with alanine aminotransferase (ALT) in the patients with CH, but not in those with HC with or without ascites. CONCLUSIONS: These results indicated that MIF, TNF-alpha and IL-6 may participate in the pathological process of CH and cirrhosis, that IL-6 seems to play an important role in ascites formation, and that se-rum levels of MIF, TNF-alpha and IL-6 appear to reflect the severity of tissue injury in HBV disease.

Dose ascites mean more severe Crohn's disease?

BACKGROUND/AIMS: Ascites that can be induced by various causes is not a rare finding in Crohn's disease. The clinical implication of ascites in Crohn's disease remains unknown in the cases without any specific cause of ascites except Crohn's disease itself. The purpose of this study was to investigate the clinical implication and characteristics of ascites in Crohn's disease. METHODS: We reviewed the medical records of the patients with Crohn's disease who underwent abdominal CT scan. Patients were categorized into two groups: patients with ascites (22 cases) and without ascites (23 cases). We compared clinical features, disease activities and clinical courses of the two groups. RESULTS: Serum albumin level was significantly lower and the C-reactive protein level was significantly higher in the ascites group than in the control group. Harvey and Bradshaw index was significantly higher in the ascites group (8.32 +/- 2.51) than in the control group (6.09 +/- 2.07) (p=0.002). The average dose of prednisolone was higher in the ascites group. On the other hand, there was no significant difference in the number of cases requiring surgery due to complication between two groups. CONCLUSIONS: Our results suggest that the presence of ascites in Crohn's disease is associated with increased disease activity and inflammations requiring more aggressive treatment.

[Clinical and experimental study of xiaoshui decoction in the treatment of primary liver cancer caused ascites].

OBJECTIVE: To observe the clinical efficacy of Xiaoshui Decoction (XSD) in treating ascites in patients suffered from primary liver cancer of Pi-deficiency with damp harassment syndrome (PDDHS) as well as to study the effect through the experiment in mice. METHODS: Sixty-one patients confirmed to be primary liver cancer of PDDHS and accompanied with ascites were randomly divided into the treated group (n=33) and the control group (n=28). The treated group was treated by XSD combined with chemotherapy by locally applying of DDP via abdominal infusion, while the control group treated by DDP infusion alone. The treatment lasted for two months. The conditions of ascites, quality of life (QOL), survival period, and TCM syndrome after treatment were observed. In the experimental study, the mice models of ascites were grouped and treated to observe the conditions of ascites and their survival period. RESULTS: The short-term total effective rate of the treated group and the control group was 42.4% and 21.4%, the interval of aspirating ascites after treatment was 17.95 +/- 9.63 days and 10.87 +/- 7.76 days, and the 1-year survival rate 33.3% and 14.3%, respectively, significant difference was shown between the two groups in the three parameters (all P < 0.05 ). QOL was improved in both groups with insignificant difference (P > 0.05). Besides, the main symptoms were improved in patients of both groups, especially in the ameliorating of fatigue, abdominal distension, nausea and vomiting. Evaluation on safety of treatment showed that XSD had no obvious toxic and adverse reaction, and so it was safe in use. Experimental study showed that on the two mice models of ascites induced by inoculating two kinds of tumor cell, the effect of XSD was superior to that of the control group in aspects of reducing ascites and prolonging survival period, showing significant difference (P < 0.05). CONCLUSION: Satisfactory short-term efficacy in treating primary liver cancer with ascites of the Pi-deficiency with damp harassment syndrome could be obtained by XSD. Its effect in prolonging survival period was confirmed by experimental study. XSD can also improve the symptoms and QOL of patients, therefore, it is an effective and reliable remedy for treatment of primary liver cancer with ascites.

[Refractory ascites and dilutional hyponatremia: current management and new aquaretics].

Ascites is the most common complication of cirrhosis and is associated with 50% mortality at 2 years if patients do not receive orthotopic liver transplantation. Recently the International Ascites Club defined ascites into three groups: In grade I ascites fluid is detected only by ultrasound; in grade II, ascites is moderate with symmetrical distention of the abdomen; and in Grade 3 ascites is large or tense with marked abdominal distention. About 10% of patients with ascites are refractory to treatment with diuretics. In refractory ascites, patients do not respond to highest doses of diuretics (spironolactone 400 mg/day and furosemide 160 mg/ day) or develop side effects (hyperkalemia, hyponatremia, hepatic encephalopathy, or renal failure) that prohibit their use. Patients may be treated either by repeated large volume paracentesis plus albumin or transjugular intrahepatic portosystemic shunts (TIPS). Dilutional hyponatremia in cirrhotic patients is defined as serum sodium < or = 130 mEq/L in the presence of an expanded extracellular fluid volume, as indicated by the presence of ascites and/or edema. This complication of cirrhotic patients with ascites has recently gained attention given that several reports indicate that when serum sodium concentration is combined with the Model for End-Stage liver disease (MELD) it improves the prognostic accuracy of MELD score in patients awaiting orthotopic liver transplant (OLT). The first step in the management of dilutional hyponatremia is fluid restriction and discontinuation of diuretics. Water restriction at 1,000 mL/day helps prevent the progressive decrease in serum sodium concentration but usually does not correct hyponatremia in most cases. Actually are developing drugs that are active orally and act by selectively antagonizing the specific receptors (V2 receptor) of arginine vasopressin. These agents act in the distal collecting ducts of the kidneys, by increasing solute free water excretion and, thus, improving serum sodium concentration in hyponatremic patients.

Role of leucocytes in ascites in the production of factor(s) stimulating differentiation of mouse myeloid leukemia cells.

Although the ascitic fluid of animals bearing various tumors and that of mice induced by complete Freund's adjuvant had high activity for inducing differentiation of myeloid leukemic cell line (M1) from an SL mouse to macrophages and granulocyte-like cells, the activity in the ascitic fluid of syngeneic mice bearing the M1 cells was markedly reduced. Macrophages and granulocytes were abundant in the active ascites of animals bearing tumors (8 to 12% of the total ascites cells) while in the ascites of syngeneic mice bearing the M1 cells they were not (0.1 to 0.7% of the total ascites cells). Appearance of lymphocytes in the ascites of both types was not significantly different. Although the conditioned media of the Ehrlich tumor cells, M1 cells, and whole ascites cells with the M1 cells were not active in inducing differentiation of the M1 cells, the conditioned media of all the ascites cells with Ehrlich tumor cells and those of peritoneal macrophages and granulocytes in mice did show a high activity. These results indicate that the peritoneal macrophages and granulocytes in the ascites are responsible for the production of factors stimulating differentiation of the M1 cells.

[Spontaneous bacterial peritonitis in patients with decompensated liver cirrhosis and "tense" ascites].

In the study 52 patients with decompensated liver cirrhosis and "tense" ascites were included. According to the clinical picture, ascites cultures and the number of polymorphonuclears in cmm of the ascitic fluid, all patients were selected in one of the following groups: 1. group of patients with sterile ascites (28), 2. group of patients with spontaneous peritonitis (16), and 3. group of patients with bacterascites (8). The results have shown that the incidence of spontaneous peritonitis is much higher in the group of "tense" ascites patients than in the group of all patients with ascites, the ratio being 30.7% compared to 6% in all cirrhotic patients with ascites. Spontaneous bacterial peritonitis correlates with increased polymorphonuclears in the ascitic fluid (p less than 0.05), decreased pH values (p less than 0.0), and increased amounts of total proteins in the ascitic fluid (p less than 0.05). The lethality rate in the group of spontaneous peritonitis and sterile ascites was 43.7% and 7.1% respectively. Early diagnosis and, of course, adequate therapy are the main points in spontaneous bacterial peritonitis.

Exchange of macromolecules between plasma and peritoneal cavity in ascites tumor-bearing, normal, and serotonin-injected mice.

Fluorescein-labeled dextrans (FITC-D) from 3 to 5000 kDa (Stokes' radii from 1 to 40 nm) were used to study influx from the plasma into the peritoneum and efflux from the peritoneal cavity into the plasma in normal and ascites tumor-bearing mice and in mice whose peritoneal vessels had been rendered hyperpermeable by serotonin. Two syngeneic transplantable murine ascites tumors were studied: mouse ovarian tumor and the TA3/St breast adenocarcinoma. To control for effects of peritoneal fluid volume, influx and efflux were also analyzed in mice that had received 5 ml of 5% bovine serum albumin i.p. as "artificial ascites." Following i.v. or i.p. injection, levels of FITC-D in the plasma and peritoneal fluid were quantitated by fluorimetry at successive time intervals from 5 to 360 min posttracer injection. Influx and efflux data were analyzed with a model consisting of three compartments (plasma, peritoneal cavity, and the extravascular space of all other organs) to yield kinetic parameters that characterized macromolecular transport. Depending on the size of the FITC-D tracer, from 3- to 50-fold more FITC-D accumulated in mouse ovarian tumor or TA3/St tumor ascites fluid, and 3- to 10-fold more FITC-D accumulated in the peritoneum of serotonin-treated than normal mice, all of it intact by gel exclusion chromatography. Influx of the FITC-D from plasma into the peritoneum, as characterized by the rate constant k1, was 2- to 40-fold greater in ascites tumor-bearing animals and 2- to 10-fold greater in serotonin-treated animals than in controls. Control animals with artificial ascites showed at most a 4-fold increase in the value of k1. As judged by fluorescence microscopy, the permeability of peritoneal-lining vessels in ascites tumor-bearing animals was greatly increased to FITC-D of 70 to 5000 kDa. Efflux of FITC-D, characterized by the rate constant k2, was reduced from 5- to 50-fold in ascites tumor-bearing animals but was unchanged or actually somewhat enhanced following serotonin treatment. Efflux in animals that had received artificial ascites was reduced 2.5- to 12.5-fold, correlating increased peritoneal fluid volume with decreased efflux. We conclude that tracer accumulation in malignant ascites fluid results from both increased influx as well as impaired efflux. Influx, and to a lesser extent efflux, were significantly affected by tracer size. However, within the range of FITC-D tested, we found no absolute size barrier to macromolecular transport from plasma to the peritoneal cavity, or vice versa.(ABSTRACT TRUNCATED AT 400 WORDS)

Patient selection and survival after peritoneovenous shunting for nonmalignant ascites.

Patient selection and survival after peritoneovenous shunting for nonmalignant ascites was assessed in 30 patients undergoing 44 peritoneovenous shunting procedures over a 5-year period. Indications for peritoneovenous shunting included refractory ascites alone, refractory ascites complicated by hepatorenal syndrome, and nonrefractory but recurrent ascites. Fifty-six percent of shunting procedures were complicated by shunt malfunction and an additional 13% ended in shunt removal or ligation. Serious perioperative morbidity occurred in 47% of patients. Mean duration of shunt function was significantly less (p less than 0.05) in the patients with hepatorenal syndrome (15 +/- 5 days) compared to the patients with refractory ascites alone (45 +/- 13 days), or the patients with nonrefractory ascites (64 +/- 34 days). Mean survival was 265 +/- 87 days. Survival of patients with nonrefractory ascites (767 +/- 214 days) was significantly longer (p less than 0.05) than that seen in patients with hepatorenal syndrome (28 +/- 5 days) or in patients with refractory ascites alone (256 +/- 148 days). Combined inhospital mortality was 30%. It was significantly greater (p less than 0.05) in patients with hepatorenal syndrome (70%) than in patients with refractory ascites alone (14%) or in patients with nonrefractory ascites (0%). We conclude that patient selection significantly influences survival after peritoneovenous shunting and may account for the varying results reported by other groups.

[Justification of routine puncture of ascites in cirrhotic patients admitted to emergency hospital units].

OBJECTIVES: Spontaneous bacterial peritonitis (SBP) is a frequent, serious, recurrent complication, occurring in 10 to 30% of cirrhotic patients hospitalized with ascites. The key to diagnosis of SBP is ascites paracentesis and polymorphonuclear count in ascitic fluid. The purpose of our study was to evaluate sensitivity and specificity of clinical and biological criteria in diagnosis of 5 BP. METHODS: We prospectively reviewed 30 adult cirrhotic patients admitted in our emergency department with ascites. Ascites paracentesis was performed in each patient, and SBP diagnosis was based on either positive bacteriological culture or polymorphonuclear count above 250/mm3 in ascitic fluid. Classical criteria for SBP were recorded: blood pressure under 90 mm of Hg, abdominal pain, temperature above 38.5 or under 36.5, jaundice, encephalopathy, increased serum bilirubin or creatinine, leukocyte blood count about 12 G/l. We evaluated sensitivity and specificity of those criteria in SBP, and compared their frequency in patients with SBP or sterile ascitic fluid. RESULTS: Thirty patients were included in our series, and in 14 of them a SBP was diagnosed. A significant difference was observed between spontaneous bacterial peritonitis and sterile ascitic fluid for abdominal pain and temperature abnormalities, but specificity and sensitivity of these criteria were very low. Moreover, SBP was asymptomatic in 7%. CONCLUSION: Due to the high rate of mortality in patients with SBP we recommend diagnostic procedures for this frequent complication as soon as patient is admitted in emergency department. This diagnosis must be based on ascitic fluid paracentesis, which has to be performed, in the emergency department, in every cirrhotic patient admitted with ascites. Indeed, SBP is often asymptomatic, and no clinical or bacteriological criteria can be considered as completely reliable for the diagnosis of spontaneous bacterial peritonitis.

[Ascites after liver transplantation in children].

The objective of this study, based on a series of 148 transplants performed in 131 children, was to evaluate the frequency, complications and predisposing factors of ascites occurring after liver transplantation (LT). The diagnosis of post-LT ascites was defined as a drainage rate greater than 25 ml/kg/day (or- > 500 ml/day) persisting for at least 72 hours after removal of the drains. Among the 123 transplants analysed, 31 (25.2%) were complicated by ascites (group I). Group II consisted of 92 LT without ascites. This ascites was predominantly lymphocytic (669 +/- 1,104/mm3), rich in proteins (32 +/- 13 g/l), with a low triglyceride concentration. The mean duration of ascites was 25 +/- 19 days. Complications of ascites included: infection of ascitic liquid (35%), respiratory complications (65%), parietal complications (50%), consumption coagulopathy (35%), functional renal failure (Creat > 130 mumol/l, 35%). There were 9 deaths (29%) in group I versus 8 in group II (p < 0.02). The predictive factors, pre-LT, of postoperative ascites included: serum bilirubin > 300 mumol/l (p < 0.02); PT < 30% (p < 0.05); and serum albumin < 30 g/l (p < 0.05). Intraoperative factors favouring the development of ascites were end-to-side cavo-caval implantation of the graft when it was reduced (p < 0.02) and a volume of transfused blood after unclamping greater than 60 ml/kg (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
