Plasminogen activators and plasminogen activator inhibitor in malignant and non-malignant ascitic fluid.

Ascitic fluid from tumour patients (hepatoma, gastric cancer, gallbladder cancer, colorectal cancer, ovarian cancer) and from non-malignant diseases (liver cirrhosis, congestive heart failure) were compared with respect to their content of determinants of the fibrinolytic system, tissue-type plasminogen activator antigen (t-PAag) and activity (t-PAact), urokinase-type plasminogen activator antigen (u-PA) and plasminogen activator inhibitor activity (PAI). Furthermore, SDS-polyacrylamide slab-gel electrophoresis (SDS-PAGE) was performed to evaluate molecular weight distribution of the detectable fibrinolytic parameters. In malignant ascites, PAI activity was three to four times higher, and increased complex formation of PAI with t-PA could be demonstrated, compared with non-malignant ascitic fluid. Tissue-type plasminogen activator antigen and activity showed a similar concentration in ascites of both study groups. Urokinase-type plasminogen activator antigen was detectable neither in ascites of malignant nor in ascites of non-malignant origin. It is concluded that t-PA is the physiological plasminogen activator in ascites and that increased PAI levels followed by increased complex formation between t-PA and PAI might reflect a reaction of the peritoneum.

Effect of transferrin concentration on bacterial growth in human ascitic fluid from cirrhotic and neoplastic patients.

Cirrhotic patients with ascites have an unusually high frequency of development of spontaneous bacterial peritonitis. Iron availability is a key factor in bacterial growth and the ability of the host to limit it is associated with resistance to infection. The present study was undertaken to evaluate the influence of iron and transferrin on bacterial growth in ascitic fluid from 25 biopsy-proven cirrhotic and nine neoplastic carcinomatous patients. No significant differences were found when comparing total ascitic fluid iron between the two groups but ascitic fluid transferrin concentration was significantly lower in cirrhotic (29.26 mg dl-1 SD 29.58) than neoplastic (96.57 mg dl-1 SD 76.01) patients. Moreover, a significant negative correlation was found between bacterial growth and transferrin concentration in ascitic fluid (P = 0.039). When the iron concentration in ascitic fluid was experimentally elevated (50 micrograms dl-1 or 150 micrograms dl-1) we observed a progressive increase in bacterial growth. If transferrin concentration is simultaneously elevated (250 mg dl-1) this increase does not occur. These findings indicate that the transferrin level is an important factor in the regulation of bacterial growth in ascitic fluid and that the low concentration found in cirrhotic patients could facilitate spontaneous bacterial peritonitis.

Norfloxacin and cisapride combination decreases the incidence of spontaneous bacterial peritonitis in cirrhotic ascites.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a serious complication of cirrhosis with ascites, having high recurrence despite antibiotic prophylaxis. Small bowel dysmotility and bacterial overgrowth have been documented to be related to SBP. The purpose of the present paper was (i) to study whether addition of a prokinetic agent to norfloxacin ameliorates the development of SBP in high-risk patients; and (ii) to identify risk factors for SBP development. METHODS: A prospective, single blinded, randomized controlled trial was conducted in high-risk cirrhotic patients with ascites who had either recovered from an episode of SBP or who had low ascitic fluid protein. Norfloxacin 400 mg once daily (group I) or norfloxacin 400 mg once daily with cisapride 20 mg twice a day (group II) was given and occurrence of side-effects of therapy and mortality were recorded. RESULTS: Of the 94 patients, 48 (51%) were in group I, and 46 (49%) in group II. The actuarial probability of developing SBP at 12 month in group I was 56.8% and in group II, 21.7% (P = 0.026). Treatment failure was observed in five patients (10%) in group I and none in group II (P = 0.003). The actuarial probability of death at 18 months was 20.6% in group I and 6.2% in group II (P = 0.1). Low serum albumin, low ascitic fluid protein and alcoholic cirrhosis were related to development of SBP (P < 0.05). Additionally, low serum albumin (2.8 g/dL), gastrointestinal bleeding, alcoholic cirrhosis and low ascitic fluid protein were significantly associated with multiple occurrences of SBP. CONCLUSIONS: Prophylaxis with norfloxacin and cisapride significantly reduces the incidence of SBP in high-risk cirrhosis patients; low serum albumin, low ascitic fluid protein and alcoholic cirrhosis predispose to the development of SBP in high-risk cirrhosis patients; and low ascitic fluid protein should also be considered as a risk factor for the development of SBP requiring prophylaxis.

Pancreatic ascites in children.

We report on three children with pancreatic ascites confirmed by endoscopic retrograde cholangiopancreaticography (ERCP) and treated with surgery. The children presented with ascites, malnutrition and severe weight loss. Pancreatic ascites was diagnosed by elevated ascitic fluid and serum amylase levels. ERCP demonstrated a pseudocyst and the site of disruption of the pancreatic duct, but not the etiology of the pancreatitis. Following a period of nutritional support, surgery was carried out. Two of the children underwent a stented transgastric drainage of the pseudocyst; a recurrent pseudocyst in one of the children required a revision cystojejunostomy. The third child was treated with a Roux-en-Y cystojejunostomy. All the children are pain-free and without ascites and are doing well on long-term follow-up. We conclude that pancreatic ascites must be considered in the differential diagnosis of intractable ascites in children. An ERCP is essential in planning management and cystoenterostomy is the definitive treatment.

The role of nitric oxide in the pathogenesis of systemic and splanchnic vasodilation in cirrhotic rats before and after the onset of ascites.

BACKGROUND: The role of nitric oxide (NO) in the pathogenesis of splanchnic arterial vasodilation in cirrhosis has been recently debated by some experimental studies. AIMS: We investigated the role of NO in the pathogenesis of the splanchnic arterial vasodilation along the course of CCl(4)-induced experimental cirrhosis. METHODS: We analyzed the effect on mean arterial pressure (MAP), cardiac output (CO), total peripheral resistance (TPR), and resistance in the superior mesenteric artery (RSMA), before and after the administration of a unspecific NO synthase (NOS) inhibitor (Nomega-nitro-L-arginine-methyl-ester, L-NAME) and a specific NOS2 inhibitor (L-N-(1-iminoethyl)-lysine, L-NIL) to cirrhotic rats with and without ascites, and to control rats. NOS2 and NOS3 protein expression was also assessed in systemic and splanchnic arteries of these animals. RESULTS: L-NAME in cirrhotic rats markedly improved MAP, and TPR and decreased CO regardless of whether they had ascites or not. L-NIL did not produce any significant effect on systemic haemodynamics in control and cirrhotic rats. NOS3 overexpression in the aorta of cirrhotic animals paralleled the progression of the liver disease. L-NAME increased RSMA in cirrhotic rats, but this effect was much less intense in rats with ascites. L-NIL had an effect only on RSMA in rats with ascites, which was of a similar extent to that produced by L-NAME. Western blot experiment showed a faint overexpression of NOS3 in the mesenteric artery of cirrhotic rats with and without ascites and a clear induction of NOS2 only in the mesenteric artery of rats with ascites. CONCLUSIONS: These results indicate that NO contributes significantly to the pathogenesis of arterial splanchnic circulation in the early stages of experimental cirrhosis but has only a minor role in its maintenance after the development of ascites. Furthermore, the expression of the different NOS isoforms varies along the course of the liver disease.

Correlation between serum-ascites albumin concentration gradient and endoscopic parameters of portal hypertension.

OBJECTIVE: We sought to determine the correlation between the level of serum-ascites albumin concentration gradient (SAAG) and the complications of portal hypertension (PHTN), manifested by the presence and grade of esophageal varices (EV). METHODS: Our study included 31 patients with ascites, demonstrated by ultrasonography, who had measurement of the SAAG. All had upper gastrointestinal endoscopy with assessment of the presence and size of EV. High SAAG was considered to be present when the SAAG was > or = 1.1 g/dl and Low SAAG when it measured < 1.1 g/dl. RESULTS: We found that 25 of 31 (80.6%) patients had High SAAG and six of 31 (19.4%) had Low SAAG. Esophageal varices were present in 17 of 25 (68%) patients with High SAAG and in none of six (0%) patients with Low SAAG (p = 0.028). In patients with alcoholic liver disease (ALD), 14 of 14 (100%) had EV. Otherwise, in patients with nonALD, only three of 11 (27.3%) had EV (p < 0.05). The presence of EV was associated with the Child-Pugh Score (p = 0.039). Among patients with High SAAG, EV were present in four of 10 (40%) with SAAG values of 1.10-1.49 g/dl; in four of 6 (66.7%) with SAAG values of 1.50-1.99 g/dl; and in nine of nine (100%) with SAAG values of > or =2.0 g/dl (p = 0.049). The size of the EV had no association with the level of SAAG in patients with High SAAG (p = 0.788), with a Pearson correlation coefficient of R = 0.54 (p = 0.005). Using the Receiver-Operating-Characteristic Curve a SAAG value of > or =1.435 +/- 0.015 g/dl was an accurate indicator of the presence of EV (cutoff point for the higher predictive value: positive = 87.5% and negative = 66.7%). CONCLUSIONS: In patients with ascites the presence of EV is associated only with patients with High SAAG. The presence of EV in patients with ascites and High SAAG is directly related to the degree of SAAG. The size of the EV in patients with ascites and High SAAG is not associated with the degree of SAAG. A SAAG value of > or =1.435 +/- 0.015 g/dl is a useful means to predict the presence of EV in patients with ascites. Finally, in patients with ascites, EV were more prevalent in those with ALD.

Ascites and liver test abnormalities during severe ovarian hyperstimulation syndrome.

OBJECTIVE: Severe ovarian hyperstimulation syndrome is an uncommon cause of ascites that is being increasingly recognized because of the high number of women undergoing assisted reproductive techniques, mainly in vitro fertilization. This prospective study investigates the clinical and biochemical characteristics of a large series of patients with this syndrome and ascites, including renal and electrolyte abnormalities, activity of neurohormonal systems participating in the regulation of extracellular fluid volume, and liver function tests. METHODS: This was a prospective longitudinal study including 50 consecutive patients with ascites due to severe ovarian hyperstimulation syndrome. Renal function, serum electrolytes, body weight, mean arterial pressure, pulse rate, plasma renin activity, plasma concentration of aldosterone, norepinephrine, antidiuretic hormone and atrial natriuretic peptide, and standard liver function tests were measured during the syndrome and 4-5 wk after recovery. A sample of ascitic fluid was obtained from eight patients for protein measurement and cell count. RESULTS: At diagnosis, patients had ascites associated with low urinary sodium excretion, oliguria, and hyponatremia. They had also markedly low arterial pressure and increased pulse rate in association with marked activation of vasoconstrictor and antinatriuretic factors. The ascitic fluid was characterized by a high protein concentration, low leukocyte count, and relatively high number of red blood cells. Fifteen (30%) patients had abnormal liver tests characterized by mild to moderate increases in AST (mean 103 +/- 17.1 IU/L) and ALT (76 +/- 8.3 IU/L), which were associated in some cases with increases in gamma-glutamyl transpeptidase or alkaline phosphatase. All abnormalities reverted to normal after the resolution of the syndrome. CONCLUSIONS: With the increasing use of assisted reproductive techniques, physicians should be aware of severe ovarian hyperstimulation syndrome as a cause of ascites. The syndrome is associated with sodium retention, hyponatremia, arterial hypotension, and marked activation of vasoconstrictor and antinatriuretic systems. In one third of patients, liver tests abnormalities are present.

Effects of a new orally active dopamine prodrug, docarpamine, on refractory ascites: a pilot study.

OBJECTIVE: Refractory ascites is a debilitating condition in patients with cirrhosis. Recently, docarpamine, an orally active dopamine prodrug, was reported to increase renal blood flow, glomerular filtration, and sodium excretion. This suggests docarpamine may be useful for the treatment of refractory ascites. METHODS: In this study, we investigated docarpamine metabolism in cirrhotic patients and its effect on refractory ascites. RESULTS: Blood samples were obtained from seven cirrhotic patients and six healthy subjects after administration of 750 mg docarpamine, and plasma levels of free dopamine were measured. In healthy subjects, maximum plasma concentration (Cmax), time taken to reach Cmax (Tmax), elimination half-life (T(1/2)), and area under the plasma concentration-time curve (AUC) of plasma free dopamine were 76.8 +/- 24.1 ng/ml, 1.3 +/- 0.2 h, 0.8 +/- 0.1 h, and 97.5 +/- 21.1 ng x h/ml, respectively. In patients with cirrhosis, Cmax (53.1 +/- 24.9 ng/ml), T(1/2) (0.8 +/- 0.1 h), and AUC (100.6 +/- 45.6 ng x h/ml) were no different from healthy subjects when comparing each parameter, whereas Tmax (2.7 +/- 0.2) was significantly longer than that of healthy subjects. We treated 10 cirrhotic patients with refractory ascites with docarpamine or placebo and the same dose of diuretics used before hospitalization. After 8 wk of docarpamine treatment, ascites disappeared completely in three of the five patients and decreased in the remainder. However, in five patients treated with placebo, ascites was not changed or increased. Side effects were not observed in any case. CONCLUSIONS: Docarpamine was found to metabolize in cirrhotic patients as well as in normal subjects and may be an effective treatment for refractory ascites.

Transjugular intrahepatic portosystemic shunt for refractory ascites: an analysis of the literature on efficacy, morbidity, and mortality.

OBJECTIVES: Transjugular intrahepatic portosystemic shunt (TIPS) is frequently used to treat patients with refractory ascites, but its role is controversial. We sought to determine from the literature the efficacy, morbidity, and mortality associated with TIPS for refractory ascites. METHODS: We searched MEDLINE and identified studies published in English from January, 1985, to March, 2003, that evaluated the effect of TIPS in patients with refractory ascites. Outcomes that were analyzed included complete resolution of ascites, reduction in ascites, mortality, encephalopathy, stenosis, and renal function. Data were analyzed on an intention to treat basis. RESULTS: Of 25 studies identified, 16 were included in the analysis. The pooled estimate for complete response at 6 months was 45% and for any response (complete and partial) was 63%. Pooled 6-month mortality after TIPS was 36%. Risk factors for mortality included renal insufficiency (serum creatinine >1.5 mg/dl), hyperbilirubinemia (total bilirubin >3 mg/dl), advanced age (>60 yr), and poor response to TIPS. The pooled rate of new or worsening encephalopathy after TIPS was 32%. In most cases, encephalopathy was managed medically or by reduction in shunt size; however, refractory cases were associated with 100% mortality in most studies. Studies reporting the effect of TIPS on kidney function showed improvement in creatinine clearance and urinary sodium excretion. CONCLUSIONS: TIPS is effective in eliminating ascites or substantially reducing ascites in cases refractory to medical therapy. Renal insufficiency, refractory encephalopathy, and hyperbilirubinemia were consistently associated with mortality after TIPS. In individuals with risk factors for mortality, alternative strategies should be recommended.

Portal hypertension: a permissive factor only in the development of ascites and variceal bleeding.

It is controversial whether the occurrence of ascites and gastrointestinal bleeding in cirrhosis is related to the severity of portal hypertension. Portal pressure was examined in 124 unselected patients with portal hypertension due to chronic liver disease to evaluate this issue. Portal pressure was less in patients without complications of chronic liver disease (11.7 +/- 3.0 mmHg, n = 16) as compared to patients who had bled from varices or erosive gastritis (16.6 +/- 3.4 mmHg, p less than 0.001, n = 49), who had ascites (16.2 +/- 3.0 mmHg, p less than 0.001, n = 78) or both (16.5 +/- 3.0 mmHg, p less than 0.001, n = 19). Portal pressure was similar in patients bleeding from varices and erosive gastritis (16.7 +/- 3.4 mmHg, n = 43; vs 16.2 +/- 4.0 mmHg, n = 6, respectively) and in patients with refractory and nonrefractory ascites (16.2 +/- 3.5, n = 21; vs 16.2 +/- 3.5 mmHg, n = 57). The lowest portal pressure recorded in a patient with variceal bleeding was 9.0 mmHg. The lowest portal pressure recorded in a patient with ascites was 8.0 mmHg. Esophageal varices (graded 0-4 at endoscopy) were larger in patients with a history of bleeding from esophageal varices as compared to patients without such a history (3.2 +/- 0.7 vs 2.0 +/- 0.9, p less than 0.001). Serum albumin concentration was greater in patients without ascites as compared to patients with ascites (33 +/- 5 vs 26 +/- 5 g/l p less than 0.001) but was similar in patients with refractory and nonrefractory ascites (25 +/- 7 vs 26 +/- 5 g/l, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Sodium retention and ascites formation in dogs with experimental portal cirrhosis.

Experimental cirrhosis was produced in dogs by the sporadic feeding of dimethylnitrosamine for the purpose of studying the temporal relationships between urinary sodium retention, plasma volume expansion, and ascites formation. Sodium retention started about 16 days following the onset of cirrhosis and preceded ascites formation by about 10 days. Plasma volume increased by 9% (P less than 0.05) within 3-4 days of sodium retention and expanded further as ascites accumulated. Splanchnic plasma volume was greater by 161 ml in 10 cirrhotic dogs with ascites than in 14 normal dogs. Nonsplanchnic volume was greater by 96 ml (P less than 0.05). Thus, the "effective" as well as the splanchnic component of the vascular space was expanded. Paracentesis did not cause the re-formation of ascites in five dogs as long as dietary salt was denied. Refeeding permitted reaccumulation of ascites and further plasma volume expansion. Renal perfusion remained constant as dogs became progressively cirrhotic. We conclude that ascites formation depends on the prior retention of urinary sodium, and occurs as an "overflow" phenomenon. A contracted effective plasma volume does not appear to be necessary for continuing sodium retention.

Dysfunction of the canine respiratory muscle pump in ascites.

Ascites, a complicating feature of many diseases of the liver and peritoneum, commonly causes dyspnea. The mechanism of this symptom, however, is uncertain. In the present study, progressively increasing ascites was induced in anesthetized dogs, and the hypothesis was initially tested that ascites increases the impedance on the diaphragm and, so, adversely affects the lung-expanding action of the muscle. Ascites produced a gradual increase in abdominal elastance and an expansion of the lower rib cage. Concomitantly, the caudal displacement of the diaphragm and the fall in airway opening pressure during isolated stimulation of the phrenic nerves decreased markedly; transdiaphragmatic pressure during phrenic stimulation also decreased. To assess the adaptation to ascites of the respiratory system overall, we subsequently measured the changes in lung volume, the arterial blood gases, and the electromyogram of the parasternal intercostal muscles during spontaneous breathing. Tidal volume and minute ventilation decreased progressively as ascites increased, leading to an increase in arterial PCO2 and parasternal intercostal inspiratory activity. It is concluded that 1) ascites, acting through an increase in abdominal elastance and an expansion of the lower rib cage, impairs the lung-expanding action of the diaphragm; 2) this impairment elicits a compensatory increase in neural drive to the inspiratory muscles, but the compensation is not sufficient to maintain ventilation; and 3) dyspnea in this setting results in part from the dissociation between increased neural drive and decreased ventilation.

Proinvasive properties of ovarian cancer ascites-derived membrane vesicles.

Malignant ovarian ascites are rich in cellular components, membrane-bound vesicles, and soluble proteins. This study focused on the structure of membrane-bound vesicles and their ability to promote invasion in cultured malignant ovarian epithelium. Membrane vesicles were derived from women with stage I-IV malignant ovarian ascites and from nonmalignant gynecologic ascites. Isolated vesicles were characterized by immunofluorescence and Western blot analysis. Using gel zymography for matrix metalloproteinase (MMP) detection and a colorimetric assay for urokinase-type plasminogen activator (uPA) analysis, we analyzed the proteinase activities of MMP-2, MMP-9, and uPA from the prepared vesicles, whole cells isolated from ascites, and the cell-free ultracentrifuged supernatant. The invasiveness of established cultured malignant ovarian epithelium on addition of ascites-derived vesicles was tested using a Matrigel-based invasion assay. Fractionation of malignant ascites revealed that extracellular matrix-degrading proteinases including MMPs and uPA are localized preferentially in membrane vesicles. All malignant vesicles tested, regardless of cancer stage, stimulated invasion. Furthermore, the combination of ovarian cancer cells and membrane vesicles resulted in greater uPA activation than that of cells or vesicles alone. Membrane vesicles from malignant ascites were also found to contain activated MMP-2, MMP-9, and uPA. Our data suggest that vesicle-stimulated proteinase activation leads to increased extracellular matrix degradation, which may facilitate tumor cell invasion and metastasis.

Accumulation of selected carotenoids, alpha-tocopherol and retinol in human ovarian carcinoma ascitic fluid.

BACKGROUND: Patients with severe forms of cancer are reported to have reduced concentrations of micronutrients in plasma due to the chronic reduction of food intake and an increased metabolism of these components. The purpose of this study was to evaluate if an accumulation of carotenoids, alpha-tocopherol and retinol in malignant ascitic fluid in women with ovarian cancer might contribute to a loss of these components from plasma. METHODS: Blood and ascitic fluid samples obtained from 21 women with ovarian carcinomas and 17 healthy controls were analyzed for retinol, retinol-binding protein (RBP), alpha-tocopherol and carotenoids. RESULTS: Plasma concentrations of all micronutrients were lower in cancer patients compared to controls. Ascitic fluid concentration of all investigated components was comparable (73-110%) to plasma. While the mean concentration of retinol in malignant ascites represented 73% of that in plasma, the concentration of RBP was less than 10% resulting in an increased mean molar ratio of retinol to RBP from 1.18 to 10.5. CONCLUSIONS: The results suggest that lower plasma concentrations of micronutrients in women suffering from ovarian carcinoma are not only caused by a cachexia-induced decrease of food intake and a higher rate of metabolic utilization, but also by a substantial yet not considered transfer from plasma into ascitic fluid possibly associated with plasma lipoproteins. This raises questions with regard to the protective function of these plasma components in ascitic fluid, the consequences of paracentesis on an additional supplementation and finally the possibility to use one or a combination of these components as an additional marker to discriminate between benign and malignant ascites.

Refractory ascites.

Patients with cirrhosis have significant abnormalities in their fluid and electrolyte balance; this is manifested mainly by the development of ascites and edema. Ascites is the most common complication of patients with cirrhosis and its development constitutes the first and most important manifestation of the disease. With disease progression, patients with advanced cirrhosis and severe urinary sodium retention develop refractory ascites, a condition in which patients do not respond to diuretics or develop severe side effects to these that preclude their use. This condition occurs in 5-10% of cases admitted to the hospital for treatment of ascites. Approximately half of these patients will die within 1 year if not transplanted; therefore, the best therapy is liver transplantation in suitable candidates. During the last two decades, significant advances have been made in regard to pathogenesis and treatment of refractory ascites. The re-introduction of therapeutic paracentesis with plasma expansion in the 1980s was a milestone in the treatment of these patients. In addition, the introduction of transjugular intrahepatic portosystemic shunts as a therapy for refractory ascites has certainly provided a reasonable alternative for those patients with preserved liver function and unwilling to undergo several taps per month. This article will discuss the pathophysiology, clinical features and therapy of refractory ascites in cirrhosis.

Prenatal diagnosis and management of fetal xerocytosis associated with ascites.

OBJECTIVES: To discuss the prenatal diagnosis and management of fetal xerocytosis associated with ascites. CASE REPORT: A 29-year-old woman with hereditary xerocytosis was found to present a fetus with severe ascites on the 20-week scan. Cordocentesis showed mild anemia and blood transfusion was discarded. Ascites worsened and 2 weeks later a new cordocentesis showed lower hematocrit values. Blood transfusion was performed but ascites remained unchanged. Cordocentesis was repeated at 28 weeks and albumin was transfused. Fetal hemoglobin was within the normal range. Peak systolic velocity of the middle cerebral artery remained normal and correctly predicted mild anemia. Expectant management was followed. An elective cesarean section was performed at 32 weeks because of breech presentation and preterm labor which did not respond to aggressive tocolysis. A female newborn weighing 2,615 g was delivered and required paracenteses and exchange transfusion. The newborn was discharged at 4 weeks of life and at 2 months of age, the ascites resolved completely. CONCLUSIONS: The mechanism of development of ascites in fetal xerocytosis remains unanswered. As ascites does not seem to be related to fetal anemia or hypoalbuminemia, does not substantially change after blood transfusion and tends to resolve in late gestation, a conservative management is reasonable if fetal anemia is not severe.

Cytologic study of ascites and the endometrium in ovarian carcinoma. Clinical significance.

OBJECTIVE: To ascertain the usefulness of endometrial cytology with ovarian cancers when examining extension of the disease and to analyze significant factors associated with migration of ovarian cancer cells into the uterine cavity. STUDY DESIGN: Cytologic results on ascites and the endometrium were analyzed in 87 patients with primary ovarian cancer in the absence of metastasis to the endometrium or cervicovagina. RESULTS: Positive results for cytology were found in 62/87 of ascites cases (71.3%) and in 20/87 endometrium cases (23.0%). The 15 cases (15/62 or 24.2%) positive for ascitic and endometrial cytology, divided clinically into stage III (6 cases) and stage IV (9 cases), were classified histologically as serous, 7 cases; mucinous, 2 cases; clear cell, 4 cases; endometrioid, 1 case; and unclassified, 1 case. Half the clear cell carcinomas (4/8 or 50.0%) were positive in the ascites and endometrium. The ascitic volume at surgery exceeded 500 mL in 9/15 cases (60.0%). CONCLUSION: Papillae with basement membrane material in the cores may be structurally associated with migration of ovarian cancer cells into the uterine cavity, especially in clear cell carcinomas. Cytologic positivity of the endometrium and ascites significantly correlated with ascitic volume.

Effective plasma volume in cirrhosis with ascites. Evidence that a decreased value does not account for renal sodium retention, a sponteneous reduction in glomerular filtration rate (GFR), and a fall in GFR during drug-induced diuresis.

A reduction in effective (nonportal) plasma volume is considered the basis for renal sodium retention, a spontaneous reduction in glomerular filtration rate (GFR), and a fall in GFR occurring during drug-induced diuresis in patients with cirrhosis and ascites. In the present study the concept of a reduced effective plasma volume in cirrhosis is challenged by two lines of evidence, even though effective plasma volume itself could not be measured. (a) Total plasma volume failed to rise in 10 patients with the spontaneous loss of ascites, the appearance of sodium in the urine, and a rise in GFR. Portal pressure remained constant in these patients as ascites left, suggesting that effective plasma volume had not increased while portal plasma volume decreased. (b) Reduction of GFR could not be prevented in five patients with cirrhosis and ascites while total plasma volume was prevented from falling with albumin infusions during drug-induced diuresis. Reduction of GFR during drug-induced diuresis in 15 patients with cirrhosis and ascites was completely reversed with saline infusion despite continued diuresis with the identical drugs, excluding drug nephrotoxicity as the cause for the reduced GFR. The ascites of cirrhosis might no longer be regarded as a cause of effective plasma volume contraction, stimulating renal sodium retention and a reduction in GFR. More likely, this form of ascites is a result of plasma volume expansion and sodium retention. The causes for renal sodium retention and a spontaneous reduction in GFR remain unknown. The cause for a fall in GFR during drug-induced diuresis also remains unknown, but effective plasma volume contraction and drug nephrotoxicity seem excluded.
