Background In contrast with other elastographic techniques, ascites is considered an exclusion criterion for assessment of fibrosis stage by transient elastography. However, a normal liver stiffness could rule out hepatic causes of ascites at an early stage. The aim of the present study was to determine whether liver stiffness can be generally determined by transient elastography through an ascites layer, to determine whether the ascites-mediated increase in intra-abdominal pressure affects liver stiffness, and to provide initial data from a pilot cohort of patients with various causes of ascites. Methods and results Using the XL probe in an artificial ascites model, we demonstrated (copolymer phantoms surrounded by water) that a transient elastography-generated shear wave allows accurate determination of phantom stiffness up to a water lamella of 20 mm. We next showed in an animal ascites model that increased intra-abdominal pressure does not affect liver stiffness. Liver stiffness was then determined in 24 consecutive patients with ascites due to hepatic (n = 18) or nonhepatic (n = 6) causes. The cause of ascites was eventually clarified using routine clinical, imaging, laboratory, and other tools. Valid (75%) or acceptable (25%) liver stiffness data could be obtained in 23 patients (95.8%) with ascites up to an ascites lamella of 39 mm. The six patients (25%) with nonhepatic causes of ascites (eg, pancreatitis, peritoneal carcinomatosis) had a significantly lower liver stiffness (<8 kPa) as compared with the remaining patients with hepatic ascites (>30 kPa). Mean liver stiffness was 5.4 kPa ± 1.3 versus 66.2 ± 13.3 kPa. Conclusion In conclusion, the presence of ascites and increased intra-abdominal pressure does not alter underlying liver stiffness as determined by transient elastography. We suggest that, using the XL probe, transient elastography can be used first-line to identify patients with nonhepatic ascites at an early stage. PMID:24367229

AIM: To investigate the mRNA expression of cyclooxygensae-2 (COX-2) in benign and malignant ascites, and to explore the difference in COX-2 mRNA expression among different diseases. METHODS: A total of 36 samples were collected from the Fifth Affiliated Hospital of Sun Yat-Sen University and divided into two experimental groups: benign ascites (n = 21) and malignant ascites (n = 15). Benign ascites included cirrhotic ascites (n = 10) and tuberculous ascites (n = 5). Malignant ascites included oophoroma (n = 7), cancer of colon (n = 5), cancer of the liver (n = 6), gastric cancer (n = 2), and bladder carcinoma (n = 1). The mRNA expression of COX-2 in ascites was examined with reverse transcriptase polymerase chain reaction (RT-PCR) technology, and the positive rate of COX-2 mRNA was compared between different diseases. RESULTS: The positive rate of COX-2 mRNA in malignant ascites was 42.9% (9/21), which was significantly higher than in benign ascites, 6.7% (1/15), difference being significant between these two groups (χ2 = 4.051, P = 0.044). The proportion of the positive rate in the malignant ascites was as follows: ovarian cancers 57.1% (4/7), colon cancer 40.0% (2/5), liver cancer 33.3% (2/6), gastric cancer 50.0% (1/2), and bladder cancer 0.00% (0/1). However, there was no significant difference in COX-2 mRNA expression among various tumors with malignant ascites (χ2 = 1.614, P = 0.806). Among the benign ascites, COX-2 mRNA levels were different between the tuberculous ascites (0/5) and cirrhotic ascites (1/10), but there was no significant difference (P = 1.000). CONCLUSION: COX-2 mRNA, detected by RT-PCR, is useful in the differential diagnosis of benign and malignant ascites, which also has potential value in the clinical diagnosis of tumors. PMID:24187465

The transport of plasma albumin and newly made albumin into ascitic fluid was studied in eight patients with cirrhosis and ascites. The thoracic duct was cannulated in two patients and lymph collected over a period of 2 hr. Simultaneously albumin-131I and carbonate-14C were injected intravenously. The albumin-131I measured the transfer of plasma albumin into ascites and into thoracic duct lymph. The carbonate-14C, by labeling newly formed albumin, permitted the estimation of the transfer of newly formed albumin into plasma, ascites, and lymph. If the newly synthesized albumin entering ascites and thoracic duct lymph is delivered initially into the plasma, then the ratios of the albumin-14C and -131I in ascites and lymph compared with the content of albumin-14C and -131I in plasma would be identical. However, if some newly formed albumin is delivered directly into ascites or lymph, the ratio for albumin-14C would be higher than that for albumin-131I in lymph or ascites. The ratios of both labeled albumins found in ascites or lymph are expressed as per cent of the total plasma pool. In the eight patients studied 4.2-11.7% of the albumin-14C in plasma was found in ascites in 2 hr whereas only 0.4-2.2% of plasma albumin-131I entered in this same period. In the two patients studied during thoracic duct lymph drainage 6.1 and 13.5% of newly made albumin-14C appeared in lymph in 2 hr whereas only 2.8 and 3.8% of plasma albumin-131I was found in the lymph. In cirrhosis with ascites some newly formed albumin entered ascites and thoracic duct lymph by a direct pathway from the liver bypassing the systemic circulation. PMID:5824072

An African pygmy hedgehog (Atelerix albiventris) was diagnosed as chylous ascites with biliary cirrhosis. Abdomenocentesis revealed a milky fluid with a 324 mg/dl triglyceride level. On serum biochemical examination, the hedgehog had hypoalbuminemia, hypoglycemia, and high blood urea nitrogen. There was no cytologic or genomic evidence of infection, and a blood culture was negative. Histopathologic examination revealed a liver with proliferative bile ducts that were often surrounded by prominent septa of fibrous connective tissue. In the area of ductular reaction, proliferative cells positive for CD66, an embryogenic antigen of epithelial cells, were revealed. The potential association between chylous ascites and liver cirrhosis is undetermined but could be an aspect of future study. This is the first description of chylous ascites in a hedgehog.

1. The objectives of the current study were to investigate the effect of incidence rate (5%, 10%, 20%, 30% and 50%) of ascites syndrome on the expression of genetic characteristics for body weight at 5 weeks of age (BW5) and AS and to compare different methods of genetic parameter estimation for these traits. 2. Based on stochastic simulation, a population with discrete generations was created in which random mating was used for 10 generations. Two methods of restricted maximum likelihood and Bayesian approach via Gibbs sampling were used for the estimation of genetic parameters. A bivariate model including maternal effects was used. The root mean square error for direct heritabilities was also calculated. 3. The results showed that when incidence rates of ascites increased from 5% to 30%, the heritability of AS increased from 0.013 and 0.005 to 0.110 and 0.162 for linear and threshold models, respectively. 4. Maternal effects were significant for both BW5 and AS. Genetic correlations were decreased by increasing incidence rates of ascites in the population from 0.678 and 0.587 at 5% level of ascites to 0.393 and -0.260 at 50% occurrence for linear and threshold models, respectively. 5. The RMSE of direct heritability from true values for BW5 was greater based on a linear-threshold model compared with the linear model of analysis (0.0092 vs. 0.0015). The RMSE of direct heritability from true values for AS was greater based on a linear-linear model (1.21 vs. 1.14). 6. In order to rank birds for ascites incidence, it is recommended to use a threshold model because it resulted in higher heritability estimates compared with the linear model and that BW5 could be one of the main components of selection goals.

Chylous ascites is infequent after abdominal surgery. We describe the case of a 43-year-old man with portal cavernomatosis who underwent surgery to insert a splenorenal shunt, which was not placed due to the absence of signs of portal hypertension. On postoperative day 20, the patient developed abdominal distension and mild dyspnea and was diagnosed with chylous ascites, which was related to the surgery. The patient was initially treated with diet and diuretics, with no clinical response, and consequently octreotide therapy was started. Four days later, the ascites was almost resolved and an ultrasound scan at 4 months showed its complete disappearance. This article demonstrates the effectiveness of octreotide in the treatment of postsurgical chylous ascites. Copyright © 2012 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

Chylous ascites is an extremely rare complication of abdominal aortic surgery. A case with a successful outcome is presented, followed by a review of the 17 published cases. Chylous ascites can result in nutritional imbalance, immunological deficit and respiratory dysfunction. Paracentesis confirms the diagnosis and provides symptomatic relief. Conservative management, beginning with a low-fat diet and medium-chain triglyceride (MCT) supplementation, is recommended, changing to total parenteral nutrition if unsuccessful. Failure of non-operative treatment may necessitate the need for laparotomy and ligation of leaking lymphatics or peritoneovenous shunting.

Spontaneous bacterial peritonitis (SBP) as a monomicrobial infection of ascites fluid is one of the most important causes of morbidity and mortality in cirrhotic patients. This study was aimed to determine the diagnostic accuracy of ascites fluid color in detection of SBP in cirrhotic cases referred to the emergency department. Cirrhotic patients referred to the ED for the paracentesis of ascites fluid were enrolled. For all studied patients, the results of laboratory analysis and gross appearance of ascites fluid registered and reviewed by two emergency medicine specialists. The sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ration of the ascites fluid gross appearance in detection of SBP were measured with 95% confidence interval. The present project was performed in 80 cirrhotic patients with ascites (52.5 female). The mean of the subjects' age was 56.25±12.21 years (35-81). Laboratory findings revealed SBP in 23 (29%) cases. Fifty nine (73%) cases had transparent ascites fluid appearance of whom 17 (29%) ones suffered from SBP. From 21 (26%) cases with opaque ascites appearance, 15 (71%) had SBP. The sensitivity and specificity of the ascites fluid appearance in detection of SBP were 46.88% (Cl: 30.87-63.55) and 87.50% (95% Cl: 75.3-94.14), respectively. It seems that the gross appearance of ascites fluid had poor diagnostic accuracy in detection of SBP and considering its low sensitivity, it could not be used as a good screening tool for this propose.

Ovarian cancer ascites is a native medium for cancer cells that allows investigation of their secretome in a natural environment. This medium is of interest as a promising source of potential biomarkers, and also as a medium for cell-cell communication. The aim of this study was to elucidate specific features of the malignant ascites metabolome and proteome. In order to omit components of the systemic response to ascites formation, we compared malignant ascites with cirrhosis ascites. Metabolome analysis revealed 41 components that differed significantly between malignant and cirrhosis ascites. Most of the identified cancer-specific metabolites are known to be important signaling molecules. Proteomic analysis identified 2096 and 1855 proteins in the ovarian cancer and cirrhosis ascites, respectively; 424 proteins were specific for the malignant ascites. Functional analysis of the proteome demonstrated that the major differences between cirrhosis and malignant ascites were observed for the cluster of spliceosomal proteins. Additionally, we demonstrate that several splicing RNAs were exclusively detected in malignant ascites, where they probably existed within protein complexes. This result was confirmed in vitro using an ovarian cancer cell line. Identification of spliceosomal proteins and RNAs in an extracellular medium is of particular interest; the finding suggests that they might play a role in the communication between cancer cells. In addition, malignant ascites contains a high number of exosomes that are known to play an important role in signal transduction. Thus our study reveals the specific features of malignant ascites that are associated with its function as a medium of intercellular communication. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

Ovarian carcinoma cells form multicellular aggregates, or spheroids, in the peritoneal cavity of patients with advanced disease. The current paradigm that ascites spheroids are non-adhesive leaves their contribution to ovarian carcinoma dissemination undefined. Here, spheroids obtained from ovarian carcinoma patients' ascites were characterized for their ability to adhere to molecules encountered in the peritoneal cavity, with the goal of establishing their potential to contribute to ovarian cancer spread. Spheroids were recovered from the ascites fluid of 11 patients with stage III or stage IV ovarian carcinoma. Adhesion assays to extracellular matrix (ECM) proteins and human mesothelial cell monolayers were performed for each of the ascites spheroid samples. Subsequently, inhibition assays were performed to identify the cell receptors involved. Most ascites samples adhered moderately to fibronectin and type I collagen, with reduced adhesion to type IV collagen and laminin. Monoclonal antibodies against the beta1 integrin subunit partially inhibited this adhesion. Ascites spheroids also adhered to hyaluronan. Additionally, spheroids adhered to live, but not fixed, human mesothelial cell monolayers, and this adhesion was partially mediated by beta1 integrins. The cellular content of the ascites fluid has often been considered non-adhesive, but our findings are the first to suggest that patient-derived ascites spheroids can adhere to mesothelial extracellular matrix via beta1 integrins, indicating that spheroids should not be ignored in the dissemination of ovarian cancer.

The decrease of erythrocyte deformability may be one of the predisposing factors for pulmonary hypertension and ascites in broiler chickens. In mammals, the cytoplasmic calcium is a major regulator of erythrocyte deformability. In this study, the erythrocyte deformability was measured, and the precise locations of Ca2+ and Ca2+ -ATPase in the erythrocytes were investigated in chickens with ascites syndrome induced by low ambient temperature. The results showed that ascitic broilers had higher filtration index of erythrocyte compared with control groups, indicating a decrease in erythrocyte deformability in ascitic broilers. The more calcium deposits were observed in the erythrocytes of ascitic broilers compared with those of the age-matched control birds. The Ca2+ -ATPase reactive grains were significantly decreased on the erythrocyte membranes of ascitic broilers. Our data suggest that accumulation of intracellular calcium and inhibition of Ca2+ -ATPase might be important factors for the reduced deformability of the erythrocytes of ascitic broilers.

Malignant ascites, occurring in advanced stages of cancer, is linked with poor prognosis and can cause invalidating symptoms. Physiopathological mechanisms of ascites formation are complex and have yet to be fully elucidated. In most cases, ascites is due to peritoneal carcinomatosis in which vascular permeability is enhanced by VEGF production while lymphatic drainage decreases. Ascites can also be secondary to portal hypertension, for example in case of multiple liver metastases, or due to lymphatic obstruction. While paracentesis and diuretics are commonly used, their efficiency has never been compared in a randomized controlled study. Paracentesis brings immediate but temporary relief in over 90% of cases, and implies multiple hospitalizations. Literature reports ascites control by aldosterone alone or in association with furosemide. But, available data is controversial, and there is no predictive factor to identify patients that respond to diuretic treatment. The indication of diuretic treatment is left to the appreciation of physicians. Existing recommendations are old, and practices influenced by results obtained in non-neoplastic ascites. Additional evidences are required before guidelines can be established for the palliative management of malignant ascites. Copyright © 2015 Société Française du Cancer.

Cell-free and concentrated ascites reinfusion therapy (CART) is expected to improve symptoms associated with refractory ascites of the decompensated liver cirrhosis patients. The aim of this study was to evaluate the safety and efficacy of the CART system performed on the decompensated liver cirrhosis patients. In this retrospective observational study, we evaluated 24 CART processes performed on 11 patients with decompensated liver cirrhosis. We evaluated the effectiveness and adverse events during CART procedures. The amounts of collected and concentrated ascites were 4491.7 ± 2222.8 mL (mean ± SD), respectively, and the concentration ratio was 22.4 ± 15.3 times, respectively. The amount of collected protein in ascites was 2.3 ± 0.5 g/dL, and concentration ratio of protein was 8.2 ± 9.4 times. Serum protein level was not significantly different between before and after CART sessions. Thus, CART allowed for the reduction of doses of albumin preparations (Alb) to be administered. CART has been reported to cause two adverse reactions: elevation of body temperature and decrease in blood pressure. In our study, decreased blood pressure was not observed even in patients with > 5 L of ascites drained. Although a transient elevation in body temperature was seen in only one patient, this febrile patient immediately returned to normal body temperature with the use of NSAIDs. In patients with refractory ascites of decompensated liver cirrhosis in whom complete cure cannot be expected, CART improves their QOL and, in terms of medical economy, allows for the reduction of doses of Alb. CART can be effectively applied as a palliative procedure for refractory ascites of decompensated liver cirrhosis patients. © 2016 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

Ascites is a common complication of advanced cancer and frequently requires paracentesis to reduce symptoms of pain, anorexia, and dyspnea. For many patients repeat paracenteses are required at short intervals. We prospectively studied 15 patients with recurrent ascites of malignancy to determine if intraperitoneal triamcinolone hexacetonide, a slowly metabolized corticosteroid, produced objective and symptomatic responses. After biochemical, radiological, and symptom assessment and the establishment of the interval between paracenteses, patients underwent large-volume paracentesis followed by intraperitoneal triamcinolone hexacetonide 10 mg/kg. Patients were followed after treatment for assessment of symptoms and physical signs of ascites. Repeat paracentesis was performed when symptomatic ascites recurred. Symptomatic ascites recurred in 13 of 15 patients, but the interval between paracenteses was extended from 9.5 +/- 1.6 days to 17.5 days (P = 0.0086). Symptom questionnaire scores assessing well-being, nausea, abdominal pain, dyspnea, appetite, appearance, and change in abdominal size on a scale from 0 to 6 averaged 3.2 +/- 0.3 at entry and 2.5 +/- 0.2 at the 2-week assessment (P = 0.026). Self-assessed symptoms, feeling of well-being, abdominal distention, and physical appearance improved significantly. The mean serum cortisol decreased from baseline, suggesting that some systemic corticosteroid absorption occurred. Thirteen of 15 patients have died, with a median survival of 42 days. Potential adverse effects included 1 episode each of transient abdominal pain, bacterial peritonitis, and localized herpes zoster infection. In patients with ascites of malignancy, intraperitoneal triamcinolone hexacetonide appears to postpone the requirement for repeat paracentesis and improve symptoms of malignant ascites.

To determine intestinal permeability, the serum tumor necrosis factor (TNF)-alpha level and urine nitric oxide (NO) metabolites are altered in liver cirrhosis (LC) with or without ascites. Fifty-three patients with LC and 26 healthy control subjects were enrolled in the study. The intestinal permeability value is expressed as the percentage of polyethylene glycol (PEG) 400 and 3350 retrieval in 8-h urine samples as determined by high performance liquid chromatography. Serum TNF-alpha concentrations and urine NO metabolites were determined using an enzyme-linked immunosorbent assay (ELISA) and Greiss reaction method, respectively. The intestinal permeability index was significantly higher in patients with LC with ascites than in healthy control subjects or patients with LC without ascites (0.88 +/- 0.12 vs 0.52 +/- 0.05 or 0.53 +/- 0.03, P < 0.05) and correlated with urine nitrite excretion (r = 0.98). Interestingly, the serum TNF-alpha concentration was significantly higher in LC without ascites than in control subjects or in LC with ascites (198.9 +/- 55.8 pg/mL vs 40.9 +/- 12.3 pg/mL or 32.1 +/- 13.3 pg/mL, P < 0.05). Urine nitrite excretion was significantly higher in LC with ascites than in the control subjects or in LC without ascites (1170.9 +/- 28.7 micromol/L vs 903.1 +/- 55.1 micromol/L or 956.7 +/- 47.7 micromol/L, P < 0.05). Increased intestinal macromolecular permeability and NO is probably of importance in the pathophysiology and progression of LC with ascites, but the serum TNF-alpha concentration was not related to LC with ascites.

Chylous Ascites: Evaluation and Management

2014-01-01

Chylous ascites refers to the accumulation of lipid-rich lymph in the peritoneal cavity due to disruption of the lymphatic system secondary to traumatic injury or obstruction. Worldwide, abdominal malignancy, cirrhosis, and tuberculosis are the commonest causes of CA in adults, the latter being most prevalent in developing countries, whereas congenital abnormalities of the lymphatic system and trauma are commonest in children. The presence of a milky, creamy appearing ascitic fluid with triglyceride content above 200 mg/dL is diagnostic, and, in the majority of cases, unless there is a strong suspicion of malignancy, further investigations are not required in patients with cirrhosis. If an underlying cause is identified, targeted therapy is possible, but most cases will be treated conservatively, with dietary support including high-protein and low-fat diets supplemented with medium-chain triglycerides, therapeutic paracentesis, total parenteral nutrition, and somatostatins. Rarely, resistant cases have been treated by transjugular intrahepatic portosystemic shunt, surgical exploration, or peritoneovenous shunt. PMID:27335837

Carvedilol, a non-selective beta-blocker (NSBB) with additional anti-alpha 1 receptor activity, is a potent portal hypotensive agent and has been used as prophylaxis against variceal bleeding. However, its safety in patients with decompensated liver cirrhosis and ascites is still disputed. In this study, we examined whether long-term use of carvedilol in patients with ascites is a risk factor for mortality. A single-centre retrospective analysis of 325 consecutive patients with liver cirrhosis and ascites presenting to our Liver Unit between 1st of January 2009 to 31st August 2012 was carried out. The primary outcome was all-cause and liver-specific mortality in patients receiving or not receiving carvedilol as prophylaxis against variceal bleeding. The final cohort after propensity score matching comprised 264 patients. Baseline ascites severity and UK end-stage liver disease (UKELD) score between carvedilol (n=132) and non-carvedilol (n=132) treated patient groups were comparable. Median follow-up time was 2.3years. Survival at the end of the follow-up was 24% and 2% for the carvedilol and the non-carvedilol groups respectively (log-rank p<0.0001). The long-term survival was significantly better in carvedilol than non-carvedilol group (log-rank p<0.001). The survival difference remained significant after adjusting for age, gender, ascites severity, aetiology of cirrhosis, previous variceal bleed, spontaneous bacterial peritonitis prophylaxis, serum albumin and UKELD with hazard ratio of 0.59 (95% confidence interval [CI]: 0.44, 0.80; p=0.001), suggesting a 41% reduction in mortality risk. When stratified by the severity of ascites, carvedilol therapy resulted in hazard ratio of 0.47 (95% CI: 0.29, 0.77; p=0.003) in those with mild ascites. Even with moderate or severe ascites, carvedilol use was not associated with increased mortality risk. Long-term carvedilol therapy is not harmful in patients with decompensated cirrhosis and ascites. The safety of carvedilol

OBJECTIVE The objective of our study was to determine the prevalence and clinical predictors of delayed contrast enhancement of ascites. MATERIALS AND METHODS In this retrospective study, 132 consecutive patients with ascites who underwent repeated abdominopelvic CT examinations performed within 7 days of each other were identified. These patients included 112 patients who received and 20 who did not receive IV contrast material at the initial CT examination. For each examination, we recorded the CT attenuation of the ascites. For the follow-up scan, the presence of delayed enhancement of ascites was defined as an increase in CT attenuation > 10 HU over baseline. The Fisher’s exact test, unpaired Student’s t test, and logistic regression were used to determine predictors of delayed enhancement of ascites. RESULTS A threshold increase in the attenuation of ascites by > 10 HU or more between the initial and follow-up CT examinations occurred only when IV contrast material was given with the initial examination. The increased attenuation was due to delayed contrast enhancement of ascites and occurred in 15 of the 112 patients (13%). Of the 16 patients scanned less than 1 day apart, 10 (63%) showed delayed enhancement of ascites. Delayed enhancement was not observed 3 or more days after IV contrast material administration. For each 1 mg/dL increase in serum creatinine level, the likelihood of delayed enhancement of ascites increased (odds ratio, 2.02; 95% CI, 1.11–3.69). Multivariate logistic regression showed that a short time interval between examinations (p < 0.001), increased serum creatinine level (p < 0.001), and presence of loculated ascites (p = < 0.01) were independent predictors of the magnitude of delayed enhancement of ascites. CONCLUSION Delayed contrast enhancement of ascites occurs commonly after recent prior IV contrast material administration and should not be mistaken for hemoperitoneum or proteinaceous fluid such as pus.

Pregnancy-associated plasma protein-A (PAPP-A) stimulates insulin-like growth factor (IGF) action through proteolysis of IGF-binding protein (IGFBP)-4. In experimental animals, PAPP-A accelerates ovarian tumor growth by this mechanism. To investigate the effect of PAPP-A in humans, we compared serum and ascites from 22 women with ovarian carcinoma. We found that ascites contained 46-fold higher PAPP-A levels as compared to serum (P < 0.001). The majority (80%) of PAPP-A was enzymatically active. This is supported by the finding that ascites contained more cleaved than intact IGFBP-4 (P < 0.03). Ascites was more potent than serum in activating the IGF-I receptor (IGF-IR) in vitro (+31%, P < 0.05); in 8 of 22 patients by more than two-fold. In contrast, ascites contained similar levels of immunoreactive IGF-I, and lower levels of IGF-II (P < 0.001). Immunohistochemistry demonstrated the presence of IGF-IR in all but one tumor, whereas all tumors expressed PAPP-A, IGFBP-4, IGF-I and IGF-II. Addition of recombinant PAPP-A to ascites increased the cleavage of IGFBP-4 and enhanced IGF-IR activation (P < 0.05). In conclusion, human ovarian tumors express PAPP-A, IGFBP-4 and IGFs and these proteins are also present in ascites. We suggest that both soluble PAPP-A in ascites and tissue-associated PAPP-A serve to increase IGF bioactivity and, thereby, to stimulate IGF-IR-mediated tumor growth. PMID:26336825

Umbilical hernia is a common abdominal complication in cirrhotic patients with ascites. Our study aimed to evaluate the correlation of umbilical hernia with the volume of ascites. Cirrhotic patients that underwent axial abdominopelvic computed tomography (CT) scans at our hospital between June 2012 and June 2014 were eligible. All CT images were reviewed to confirm the presence of umbilical hernia. The volume of ascites was estimated by five-point method. One hundred and fifty-seven patients were enrolled into this study. Among them, 101 patients had ascites and 6 patients had umbilical hernia. Alkaline phosphatase (AKP) and serum sodium were significantly lower in patients with umbilical hernia (P = 0.008, P = 0.011, respectively). Child-Pugh scores and the volume of ascites were significantly higher in patients with umbilical hernia (P = 0.03, P < 0.0001, respectively). Correlation analysis demonstrated that the volume of ascites, Child-Pugh scores, and blood ammonia had positive correlations with umbilical hernia (r = 0.4579, P < 0.0001; r = 0.175, P = 0.03; r = 0.342, P = 0.001, respectively) and that serum sodium had a negative correlation with umbilical hernia (r = -0.203, P = 0.011). In patients with ascites ≥2000 mL, only AKP was significantly associated with umbilical hernia (P = 0.0497). No variables were significantly associated with umbilical hernia in a subgroup analysis of patients matched according to the volume of ascites. The volume of ascites has a positive correlation with umbilical hernia. However, the factors associated with umbilical hernia in patients with severe ascites remain unclear. © 2016 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

AIM: To assess how ascites and alpha-fetoprotein (AFP) added to the Barcelona Clinic Liver Cancer (BCLC) staging predict hepatocellular carcinoma survival. METHODS: The presence of underlying cirrhosis, ascites and encephalopathy, Child-Turcotte-Pugh (CTP) score, the number of nodules, and the maximum diameter of the largest nodule were determined at diagnosis for 1060 patients with hepatocellular carcinoma at a tertiary referral center for liver disease in Egypt. Demographic information, etiology of liver disease, and biochemical data (including serum bilirubin, albumin, international normalized ratio, alanine and aspartate aminotransferases, and AFP) were evaluated. Staging of the tumor was determined at the time of diagnosis using the BCLC staging system; 496 patients were stage A and 564 patients were stage B. Patients with mild ascites on initial ultrasound, computed tomography, or clinical examination, and who had a CTP score ≤ 9 were included in this analysis. All patients received therapy according to the recommended treatment based on the BCLC stage, and were monitored from the time of diagnosis to the date of death or date of data collection. The effect of the presence of ascites and AFP level on survival was analyzed. RESULTS: At the time the data were censored, 123/496 (24.8%) and 218/564 (38.6%) patients with BCLC stages A and B, respectively, had died. Overall mean survival of the BCLC A and B patients during a three-year follow-up period was 31 mo [95% confidence interval (95%CI): 29.7-32.3] and 22.7 mo (95%CI: 20.7-24.8), respectively. The presence of ascites, multiple focal lesions, large tumor size, AFP level and CTP score were independent predictors of survival for the included patients on multivariate analysis (P < 0.001). Among stage A patients, 18% had ascites, 33% had AFP ≥ 200 ng/mL, and 8% had both. Their median survival in the presence of ascites was shorter if AFP was ≥ 200 ng/mL (19 mo vs 24 mo), and in the absence of ascites

Endometriosis-related ascites is rare and is frequently confused with an ovarian malignancy. Since it affects women in reproductive age, its diagnosis and therapy are even more challenging. These patients usually present with abdominal distension, pelvic pain, and weight loss, but a careful questioning usually reveals the typical endometriosis symptoms-such as dysmenorrhea and dyspareunia. We present three cases of endometriosis-related ascites, one of them with pleural effusion. All cases were associated with extensive disease and required laborious laparoscopic surgery, medical therapy with gonadotropin releasing hormone analogs, and long-term follow-up. One of the patients delivered twins following an in vitro fertilization (IVF) cycle without recurrence of ascites. We aim to raise awareness toward the importance of considering endometriosis in a patient with ascites of unknown origin.

A variety of options have been proposed to treat malignant ascites but most of them have failed to reach a significant impact in terms of palliation. Laparoscopic hyperthermic intraperitoneal chemotherapy (LHIPEC) could represent a good therapeutic tool for patients in whom medical therapies have failed and peritoneovenous shunting is contraindicated. Here we present a case of a 49-year-old woman with malignant ascites secondary to peritoneal spreading of a right pleural mesothelioma. After failure of medical therapy, the patient underwent LHIPEC with Cisplatin 25 mg/m/L and Doxorubicin 7 mg/m/L. A dramatic reduction of ascites was documented in the postoperative period and the patient experienced complete abdominal symptom relief. Ascites did not recur during a follow-up period of 6 months. LHIPEC could be a good therapeutic option to palliate malignant ascites from mesothelioma in cases not eligible for a radical treatment. Further studies are needed to standardize dosage and perfusion parameters.

We present the case of a 37-year-old male, admitted to our clinic with abdominal tenderness, right supraclavicular tumour, and ascites. The presence of ascites was incidentally reported 6 years before, but no other evaluation was done at that moment or during this period. Abdominal ultrasound and CT scan revealed moderate ascites, perivascular adenopathies, and multiple abdominal cystic lesions, while thoracic CT scan revealed the same lesions in mediastinum. Laboratory data were within normal limits, including the tumoral markers, and the tests for hydatid cysts. A biopsy from the right supraclavicular nodule was performed, and based on usual and immunohistochemical stains (calretinin, mesotheline, CK 5/6, CK 7, CK18 diffusely positive in mesothelial cells, and CEA -M, bcl-2 and vimentin negative), suggested the diagnosis of mesothelioma. Based on these results, the diagnosis of "multicystic mesothelioma" was made. The patient was referred for surgery.

Chylous ascites is an unusual condition with many causes. Two cases are presented in which it appeared to be related to whole pelvis irradiation in one patient for carcinoma of the vagina and in another for carcinoma of the vulva. The diagnosis is made by paracentesis and analysis of the fluid. The underlying disease usually requires identification by exploratory laparotomy. Although a malignant process is the most common cause, the only findings in the authors' cases were widespread radiation changes in the intestine. After diagnosis treatment by low-fat diet with medium-chain triglyceride supplements resulted in disappearance of chylous ascites.

Giant ovarian cysts are tumours of the ovary presenting with diameters greater than 10 cm. Giant ovarian cysts have become rare in recent days as they are diagnosed and managed early due to the availability of good imaging modalities. The aim of this case report is to show how a huge cystic ovarian mass can mislead the diagnosis of ascites in a postmenopausal woman. Factors associated with late presentation of giant ovarian cysts in sub-Saharan Africa have also been discussed. We present the case of a 65-year-old grand multiparous woman who was referred to our centre with a grossly distended abdomen misdiagnosed as a massive ascites. Abdominopelvic ultrasound scan revealed a right giant multiloculated ovarian cyst. She benefited from a cystectomy with an uneventful postoperative stay. Histopathology revealed mucinous cystadenoma. Large cystic ovarian tumours can present masquerading as massive ascites and misleading diagnosis as in this case report. We report this case to increase the suspicion index of a large ovarian cyst in all women presenting with massive ascites.

To evaluate the technical feasibility of artificial ascites formation using an angiosheath before percutaneous radiofrequency ablation (RFA) for hepatic tumours and to determine predictive factors affecting the technical failure of artificial ascites formation. This retrospective study was approved by the institutional review board. One hundred and thirteen patients underwent percutaneous RFA of hepatic tumours after trying to make artificial ascites using an angiosheath to avoid collateral thermal damage. The technical success rate of making artificial ascites using an angiosheath and conversion rate to other techniques after initial failure of making artificial ascites were evaluated. The technical success rate for RFA was assessed. In addition, potential factors associated with technical failure including previous history of transcatheter arterial chemoembolization (TACE) or RFA, type of abdominal surgery, and adjacent perihepatic structures were reviewed. Predictive factors for the technical failure of artificial ascites formation were analysed using multivariate analysis. The technical success rates of artificial ascites formation by angiosheath and that of RFA were 84.1% (95/113) and 97.3% (110/113), respectively. The conversion rate to other techniques after the failure of artificial ascites formation using an angiosheath was 15.9% (18/113). Previous hepatic resection was the sole independent predictive factor affecting the technical failure of artificial ascites formation (p<0.001, odds ratio = 29.03, 95% confidence interval: 4.56-184.69). Making artificial ascites for RFA of hepatic tumours using an angiosheath was technically feasible in most cases. However, history of hepatic resection was a significant predictive factor affecting the technical failure of artificial ascites formation. Copyright © 2014 The Royal College of Radiologists.

Ascites is commonly found in patients with liver cirrhosis. Although conservative therapy is often the ideal choice of care with these patients who also have symptomatic pelvic organ prolapse, this may fail and surgical methods may be needed. Literature is limited regarding surgical repair of prolapse in the setting of ascites. The authors present the surgical evaluation and management of a 63-year-old woman with recurrent ascites from liver cirrhosis who failed conservative therapy. With adequate multidisciplinary care and medical optimization, this patient underwent surgical therapy with resolution of her symptomatic prolapse and improved quality of life.

2004-09-01

Effects of coenzyme Q10 (CoQ10) supplementation on growth performance and ascites were studied in broilers. One hundred eighty 1-d-old Arbor Acre male broiler chicks were randomly allocated into 3 groups with 6 replicates each. From d 8, the diets were supplemented with CoQ10 at levels of 0, 20, and 40 mg/kg, respectively. From d 15 to 21, all the chicks were exposed to low ambient temperature (15 to 18 degrees C) to induce ascites. Average feed intake, BW gain, and feed conversion ratio of the broilers during 0 to 3 wk, 3 to 6 wk, and 0 to 6 wk were measured. The results showed that there were no influences observed on broilers' growth performance, but the mortality due to ascites was reduced by CoQ10 supplementation (P < or = 0.05). Erythrocyte osmotic fragility (EOF) was significantly decreased by 40 mg/kg CoQ10 compared with the control, but no significant changes were observed on blood packed cell volume (PCV) among the treatments. Pulmonary arterial diastolic pressure was significantly decreased on d 36, but no significant changes were observed on right ventricular pressure (RVP), pulmonary arterial systolic pressure, and the maximum change ratio of right intraventricular pressure (+/- dp/ dtmax). Ascites heart index (AHI) was significantly decreased by 40 mg/kg CoQ10 supplementation (P < or = 0.05). The results of this study suggested that CoQ10 has a beneficial effect in reducing ascites mortality in broilers, and 40 mg/kg CoQ10 seems to be more effective than 20 mg/ kg CoQ10.

The purpose of this study is to investigate the value of 18 F-FDG PET/CT combined with assessment of tumor markers in serum or ascites for the diagnosing and determining the prognosis of benign and malignant ascites. Patients with ascites of unknown cause who underwent evaluation with FDG PET/CT were included in this retrospective study. The maximum standardized uptake value (SUV max ) and levels of the tumor markers carbohydrate antigen-125 (CA-125) and carcinoembryonic antigen (CEA) in serum and ascites were recorded. The diagnostic values of FDG PET/CT, CEA and CA-125 levels in serum or ascites, and the combination of imaging plus tumor marker assessment were evaluated. Factors that were predictive of survival were also analyzed. A total of 177 patients were included. Malignant ascites was eventually diagnosed in 104 patients, and benign ascites was diagnosed in the remaining 73 patients. With the use of FDG PET/CT, 44 patients (42.3%) were found to have primary tumors. The sensitivity, specificity, and accuracy of FDG PET/CT were 92.3%, 83.6%, and 88.7%, respectively. CA-125 levels in serum and ascites showed much better sensitivity than did CEA levels, but they showed significantly lower specificity. If the combination of tumor markers and FDG PET/CT was analyzed, the sensitivity, specificity, and accuracy of tumor markers in serum were 96.6%, 78.1%, and 88.7%, and those of tumor markers in ascites were 97.7%, 80.0%, and 90.4%, respectively. Sex may be an important factor affecting survival time (hazard ratio, 0.471; p = 0.004), but age, CEA level, and FDG PET/CT findings could not predict survival. FDG PET/CT combined with assessment of tumor markers, especially CEA, increased the efficacy of diagnosis of ascites of unknown causes. Male sex conferred a poorer prognosis, whereas age, CEA level, and FDG uptake had no predictive significance in patients with malignant ascites.

Neutrophil gelatinase-associated lipocalin (NGAL) is a marker of both tissue injury and infection. Urine NGAL levels strongly predict acute kidney injury and mortality in patients with cirrhosis, but ascites NGAL is not well characterized. We hypothesized that ascites NGAL level is a marker of spontaneous bacterial peritonitis (SBP) and mortality risk in patients with cirrhosis. Hospitalized patients with cirrhosis and ascites undergoing diagnostic paracentesis were prospectively enrolled and followed until death or discharge. Patients with secondary peritonitis, prior transplantation, or active colitis were excluded. NGAL was measured in the ascites and serum. Ascites NGAL level was evaluated as a marker of SBP (defined as ascites absolute neutrophil count > 250 cells/mm 3 ) and predictor of in-patient mortality. A total of 146 patients were enrolled, and of these, 29 patients (20%) had SBP. Baseline characteristics were similar between subjects with and without SBP. Median (IQR) ascites NGAL was significantly higher in patients with SBP compared to those without SBP (221.3 [145.9-392.9] vs. 139.2 [73.9-237.2], p < 0.01). Sixteen (11%) patients died in the hospital. In the final multivariable model, ascites NGAL (OR 1.02 per 10 units, p < 0.01) remained predictive of in-hospital mortality, controlling for SBP (OR 9.76, p < 0.01) and MELD (OR 1.11, p = 0.01). In ROC analysis, ascites NGAL had an AUC of 0.79 for inhospital mortality, and the final model including ascites NGAL, MELD, and SBP had an AUC of 0.94. Ascites NGAL level may be a biomarker of peritonitis in hospitalized patient with cirrhosis and an independent predictor of short-term in-hospital mortality, even controlling for SBP and MELD.

Primary volvulus of the small intestine associated with chylous ascites is very rare, with only four reported cases. In this paper, we report a new case of primary volvulus associated with chylous ascites. The patient was a 70-year-old man. After experiencing bloating and abdominal pain for several hours, he called an ambulance and underwent an emergency examination at our hospital. Abdominal distension, pressure pain, and rebound tenderness were observed throughout his entire abdomen. The patient had a history of hypertension for which he was receiving oral treatment. Abdominal contrast-enhanced computed tomography (CT) revealed an edematous change in the intestinal membrane and volvulus of the small intestine. As findings suggestive of ischemia were observed in part of the intestines, emergency surgery was performed on the day of admission. Open surgery revealed approximately 500 mL of chylous ascites in the abdominal cavity. The small intestine had twisted 180° in a counter-clockwise direction at the root of the superior mesenteric artery, and the mesentery appeared milky white with edematous changes extending 75 to 240 cm from the ligament of Treitz. There was no evidence of intestinal necrosis; therefore intestinal resection was not performed. The volvulus of the small intestine was corrected. Moreover, because there was no other underlying disease observed, surgery was completed. The ascites collected during surgery revealed high levels of triglycerides at 332 mg/dL, and chylous ascites was diagnosed. An abdominal CT performed on the third day after surgery showed an improvement in intestinal edema, and primary volvulus of the small intestine associated with chylous ascites was diagnosed. Postoperative progress was good, and the patient was discharged on hospital day 10.

Refractory peritonitis remains a thorny issue for patients with chronic peritoneal dialysis (PD). Shortly after catheter removal, some patients develop persistent peritoneal inflammation and ascites formation, which require percutaneous drainage for symptom relief. Our study aimed at finding the risk factors for this kind of event. A total of 47 PD patients complicated with refractory peritonitis who underwent catheter removal between January 2009 and December 2011 were enrolled in this study. Data were compared between patients with and without the development of symptomatic ascites requiring drainage during hospitalization. Among the 47 refractory peritonitis patients, 15 patients developed symptomatic ascites that needed further drainage shortly after catheter removal during hospitalization. The following factors were associated with an increased risk: longer dialysis duration, higher peritoneal Kt/V urea, and a significant rise in serum C-reactive protein (CRP) level after catheter removal. These patients had a prolonged hospital stay (62 vs 21 days, P < 0.001) and a significantly higher risk of recurrent loculated ascites during subsequent 6 months of follow-up (33.3 vs 6.2 %, P = 0.022) compared with patients who did not develop ascites requiring drainage during hospitalization. A significant portion of patients with refractory PD peritonitis experienced ascites requiring drainage shortly after catheter removal, which led to a prolonged hospitalization. Whether routine drain placement at the time of catheter removal for this high-risk group would be of benefit warrants further prospective studies.

Umbilical hernia in the cirrhotic patient is frequently seen in the setting of refractory ascites. This article reports a rare case of spontaneous rupture of a recurrent umbilical hernia in a patient with persistent ascites, following an acute increase in intra-abdominal pressure, leading to bowel evisceration. This case highlights a potentially fatal complication of umbilical hernia in the setting of chronic ascites, which was successfully managed with prompt surgical intervention. PMID:24964319

Anidulafungin concentrations were quantified with high-pressure liquid chromatography (HPLC) and UV detection of the ascites fluid and pleural effusion of 10 adult critically ill patients. Samples were collected from ascites fluid and from pleural drains or during paracentesis and thoracentesis, respectively. Anidulafungin levels in ascites fluid (0.12 to 0.99 μg/ml) and in pleural effusion (0.32 to 2.02 μg/ml) were below the simultaneous levels in plasma (1.04 to 7.70 and 2.48 to 13.36 μg/ml, respectively) and below the MIC values for several pathogenic Candida strains.

2008-09-01

We aimed to determine the expression of vascular endothelial growth factor (VEGF) and the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of cells isolated from ascites in the hen model of ovarian cancer. Ovarian tumor and normal ovary were collected from hens and ascites cells were isolated from hens with ovarian cancer. Quantitative real-time PCR was used to quantify mRNA expression. Immunohistochemical and/or Western blot analyses were used to localize protein expression in ovarian tumors, normal ovaries, and ascites cells. Cells were treated with a nonspecific, COX-1-specific, or COX-2-specific NSAID and proliferation was determined. VEGF mRNA was increased in ascites cells and there was a trend for a correlation between VEGF mRNA in ascites cells and ascites volume. VEGF protein was localized to theca cells of normal ovaries, in glandular areas of tumors, and to the cytoplasm of ascites cells. Aspirin and a COX-1-specific inhibitor decreased the proliferation of ascites cells, whereas a COX-2-specific inhibitor did not. VEGF may play a role in ovarian cancer progression in the hen and the proliferation of ascites cells can be decreased by targeting the COX-1 but not COX-2 pathway.

Klippel-Trenaunay syndrome is a rare disease characterized by capillary malformationsand soft tissue and bony hypertrophy and atypical varicosities. Management of this syndrome is focused primarily on treatment of the complications that arise from these malformations. Ascites and lymphedema are two of the more common complications in these patients. A 15-year-old female with Klippel-Trenaunay syndrome presented with chylous ascites, vaginal drainage, and unilateral lower extremity lymphedema. Treatment included dilation, hysteroscopy and curettage, and laparoscopic evacuation of abdomino-pelvic ascites with resolution of symptoms for 32 months. Repeat laparoscopic drainage was successful and remains symptom free after 12 months. Vaginal drainage of chylous ascites is a rare complication from Klippel-Trenaunay syndrome and can be successfully managed by techniques to remove abdomino-pelvic ascites.

Nephrotic syndrome is considered a rare cause of chylous ascites. Intestinal lymphangiectasia in a background of chylous ascites and without any lymphatic obstruction has been reported in association with yellow nail syndrome, which is a rare clinical occurrence in itself. The existence of chylous ascites, duodenal and splenic lymphangiectasia (without any lymphatic obstruction) and nephrotic syndrome in the form of focal segmental glomerulosclerosis in the same patient makes this case the first of its kind to be reported in the literature. Here we report the case of a 54-year-old Asian man who presented with recurrent episodes of anasarca for approximately 25 years. He was subsequently found to have chylous ascites, lymphangiectasia and persistent proteinuria. A renal biopsy revealed focal segmental glomerulosclerosis, not otherwise specified. A lymphangiogram, which was performed with the purpose of addressing the intestinal lymphangiectasia, failed to demonstrate any abnormality of lymphatic channels. He was put on oral steroids with consequent remission of his oedema and proteinuria. This case highlights the fact that duodenal and splenic lymphangiectasia can exist in a scenario of chylous ascites without any obvious obstruction of lymphatic channels and in the absence of yellow nail syndrome. This case also signifies that chylous ascites may be a rare presenting feature of nephrotic syndrome and hence this aspect should be considered while in diagnostic dilemma regarding such a clinical presentation.

Ascites usually occurs in the setting of end-stage liver disease and low serum albumin and is associated with increased mortality. However, some patients develop ascites despite normal serum albumin (NSA), when a higher portal pressure and/or enhanced renal sodium retention would be expected. This study investigated the relationship between the hepatic venous pressure gradient (HVPG) and serum albumin in ascitic patients with different etiologies of cirrhosis and mortality. Records of all patients with non-malignant ascites who underwent HVPG measurement from 2005 to 2009 were reviewed. One hundred and thirty-eight 138 patients met inclusion criteria; 18.8% had NSA. No difference in sodium excretion or diuretic use was noted in patients with and without NSA. NASH patients were more likely to have a NSA (34.2% vs 12.4%; P=0.001) as well as lower HVPG (15 vs 17.9 mmHg; P=0.009) compared to other etiologies. MELD and HVPG predicted overall survival. However, mortality did not differ by disease etiology, though NASH patients had lower CTP (7.6 vs 8.5; P<0.001) and MELD (15.6 vs 18.1; P=0.09) scores, particularly among patients who died. In patients with ascites and NSA, there were no increase in HVPG or urinary sodium retention. NASH patients with ascites had lower HVPG and a higher prevalence of NSA. They also had a higher mortality relative to MELD and CTP scores in other patients. In these patients, mechanisms other than portal and oncotic pressures and sodium retention play a role in ascites development, and increase mortality rate when complicated by low albumin.

Within-line opportunities for selection against ascites were studied in a data set comprising a 10-line comparison. The study attempted to reveal whether contrasts between lines provide reliable candidate traits for within-line selection. Mortality was chosen as the reference trait. As no pedigree information was available, a trait was required that related mortality to the nonmortality data. By principal component analysis, such a trait (ASC_INDIC = ascites indicator) was developed from pathology data. The composite trait ASC_INDIC ranked lines well for their mortality figures (r = 0.96), from which it was concluded that ASC_INDIC represents an underlying continuous ascites trait. Between lines, blood gas traits seemed to be the most promising traits. Within lines, performance traits appeared to be highly correlated to ascites. Comparison of within-line variation to between-line contrasts revealed considerable differences. The high correlation of the blood gas traits with mortality was not present within lines. However, although the magnitude was considerably reduced, the nature of the blood gas traits in their relationship to ascites was similar within and between lines. The study primarily demonstrates that contrasts between lines carry systematic but limited information for within-line coherence. Therefore, line contrasts must be interpreted with care when aiming to study genetic variation and coherence within lines.

Cell-free and concentrated ascites reinfusion therapy (CART) is a very useful treatment method for refractory ascites but is difficult for many hospitals to employ due to its need for specialized equipment. We have therefore developed drop-type with adjustable concentrator CART (DC-CART) that uses a drop-type filtration mechanism and requires only a simple pump and pressure monitor for its concentration process. Easy adjustment of ascites concentration is possible through a recirculation loop, and filter membrane washing is aided by DC-CART's external pressure-type filtration to enable the processing of any quality or quantity of ascites. Moreover, the absence of a roller pump before filtration avoids inflammatory substance release from compressed cells. A total of 268 sessions of DC-CART using ascites from 98 patients were performed with good clinical results at our hospitals between January 2012 and June 2016. This report presents the detailed methods of DC-CART and summarizes its clinical effectiveness using patient ascites and blood data obtained from 59 sessions between March 2015 and February 2016. This novel technique successfully processed refractory ascites in numerous diseases with no serious adverse events. DC-CART could concentrate large amounts of ascites (from median weight: 4900 g [max: 20 200 g] to median weight: 695 g; median concentration ratio: 7.4), and a high amount of protein (median weight: 73 g [max: 294 g]) could be reinfused. Serum albumin levels were significantly increased (P = 0.010) and kidney function and systemic hemodynamics were well maintained in treated subjects. Additional concentration of ascites and adjustment of ascites volume were easily performed by recirculation (from median weight: 615 g to median weight: 360 g; median concentration ratio: 1.5). Time was needed during DC-CART for filter membrane cleaning, especially for viscous ascites. Overall, DC-CART represents a safe and useful treatment method for various forms

The role of nonselective beta-blockers in cirrhotic patients with ascites has been recently questioned; however, definitive evidence in this regard is still lacking. To analyze published data on the influence of nonselective beta-blockers as compared to control group on survival of cirrhotic patients with ascites. Computerized bibliographic search on the main databases was performed. Hazard ratios from Kaplan-Meier curves were extracted in order to perform an unbiased comparison of survival estimates. Secondary outcomes were mortality in patients with refractory ascites, pooled rate of nonselective beta-blockers interruption, spontaneous bacterial peritonitis and hepato-renal syndrome incidence. Three randomized controlled trials and 13 observational studies with 8279 patients were included. Overall survival was comparable between the two groups (hazard ratio = 0.86, 0.71-1.03, p = 0.11). Study design resulted as the main source of heterogeneity in sensitivity analysis and meta-regression. Mortality in refractory ascites patients was similar in the two groups (odds ratio = 0.90, 0.45-1.79; p = 0.76). No difference in spontaneous bacterial peritonitis (odds ratio = 0.78, 0.47-1.29, p = 0.33) and hepato-renal syndrome incidence (odds ratio = 1.22, 0.48-3.09; p = 0.67) was observed. Pooled rate of nonselective beta-blockers interruption was 18.6% (5.2-32.1%). Based on our findings, nonselective beta-blockers should not be routinely withheld in patients with cirrhosis and ascites, even if refractory.

Rhino- and/or otoliquorrhea can be diagnosed by detecting beta-trace protein (β-TP) in nasal or ear secretions, as β-TP is found in high concentrations in cerebrospinal fluid (CSF) but not in serum. CSF fistulae following trauma or surgery can also occur at other anatomical sites, resulting in CSF leakage into the thoracic and abdominal cavities. By analogy, determination of ß-TP has also been used to diagnose CSF admixture in pleural effusions and ascites. However, no systematic study has yet evaluated the concentrations of β-TP in such fluids in the absence of CSF. To determine the validity of β-TP determination as a marker for the presence of CSF, we investigated β-TP concentrations in pleural effusions and ascites without CSF admixture. Patients from whom samples of ascites or pleural effusion and a paired plasma sample were available were investigated. One hundred sixty-four patients were prospectively recruited. ß-TP concentrations were determined by nephelometry. Mass spectrometric proteome analysis confirmed the presence of ß-TP in the samples. Median β-TP concentrations detected in ascites and pleural effusions (range, 0.014-26.5 mg/L, median 2.29 mg/L) exceeded the corresponding plasma concentrations 2.6-fold. According to cutoffs published to diagnose rhino- and otoliquorrhea, between 6.1% and 95.7% of the specimens would have been erroneously rated CSF-positive. Protein analysis confirmed the presence of β-TP in pleural effusion and ascites. Ascites and pleural effusion contain high concentrations of β-TP that exceed the levels in corresponding plasma. Therefore, β-TP is not a specific marker for the presence of CSF in these fluids.

Ascitic fluid antibody produced in C57/B1 mice immunized with Friend leukemogenic virus exhibited potent neutralizing activity. In vitro neutralization tests revealed that a mean neutralization index of 3.0 was achieved, and it was shown by sucrose gradient ultracentrifugation that this antibody resembled the 7S type. A mean yield of 6.7 ml of fluid per mouse per weekly paracentesis was obtained over an 8-week period. The ascitic fluid antibody to Friend virus was also active in vivo. Mice given antibody 3, 5, 7, and 9 days after infection with Friend virus did not develop the splenomegaly characteristic of Friend disease. PMID:16349755

To evaluate the feasibility, safety and technical efficacy of ultrasound-guided percutaneous microwave ablation with artificial ascites for adenomyosis. Between May 2015 and May 2016, a total of 25 patients with symptomatic adenomyosis who underwent ultrasound-guided percutaneous microwave ablation with artificial ascites were included in this retrospective study. A matching cohort of 50 patients underwent ultrasound-guided percutaneous microwave ablation without artificial ascites as controls. The technical efficacy, complications and short-term treatment effectiveness were assessed and compared with the controls. Artificial ascites was successfully achieved in all of the 25 patients with the administration of a median of 550 mL (range, 250-1200 mL) of solution. There was substantial improvement in achieving a better antenna path in 100% (20/20) of the cases with a poor antenna path. The complete separation was achieved in 23 of 25 patients. The mean ablation time was 26.5 ± 7.3 min and the median non-perfusion volume ratio was 76% which was similar to the control group (p > .05). No serious complications were observed. Patient pain scores for dysmenorrhoea showed a statistically significant decline from the baseline of 6.71 ± 0.96 to 2.92 ± 0.79 and the symptom severity score declined statistically significantly from 21.8 ± 5.5 to 16.4 ± 4.8 at 3 months follow-up. Percutaneous microwave ablation with artificial ascites is feasible, safe and can be effective in improving access for treatment of adenomyosis.

Drainage of malignant ascites: patient selection and perspectives

Malignant ascites (MA) is a sign of advanced cancer and poor prognosis. MA can result in impairment in quality of life (QOL) and significant symptoms. As a supportive treatment, ascites can be drained by paracentesis (PC), percutaneously implanted catheters (tunneled, untunneled, central venous catheters), or peritoneal ports, or peritoneovenous shunts. The aim of this study was to evaluate the effectiveness, safety, and patient-reported outcomes (PRO) of different drainage methods for the management of MA. A systematic review of the literature was performed, and 32 original articles met the inclusion criteria. Patients selected for permanent drain insertion demonstrated symptoms related to MA and had undergone repeated PC. The primary focus of the reviewed articles was procedural safety issues. The rate of technical success of drainage device installation was 100%. Most patients experienced improvements in symptom control after ascites drainage. When analyzed together, 19.7% (255/1297) of patients experienced any complication and 6.2% (81/1297) experienced serious adverse events during MA drainage. Complications were reported for every drainage method; however, the least occurred after PC or central venous catheter, while the most serious occurred after peritoneovenous shunts. Adverse events were as follows: catheter obstruction: 4.4%, infection: 4.1%, leakage: 3.5%, catheter dislodgment: 2.3%, hypotension: 0.6%, injuries during device insertion: 0.6%, renal impairment: 0.5%, electrolyte imbalance: 0.2%, other: 3.6%. PRO and QOL endpoints were available for 12 studies. When PRO were measured using an interview, a significant improvement in symptom control and QOL was reported in almost all patients. Once standardized questionnaires were used, improvements in symptomatic scores and role functioning were observed. Deterioration was observed in cognitive and emotional subscales. MA drainage is a safe and effective method to control symptoms associated with ascites

Malignant ascites: A review of prognostic factors, pathophysiology and therapeutic measures

Malignant ascites indicates the presence of malignant cells in the peritoneal cavity and is a grave prognostic sign. While survival in this patient population is poor, averaging about 20 wk from time of diagnosis, quality of life can be improved through palliative procedures. Selecting the appropriate treatment modality remains a careful process, which should take into account potential risks and benefits and the life expectancy of the patient. Traditional therapies, including paracentesis, peritoneovenous shunt placement and diuretics, are successful and effective in varying degrees. After careful review of the patient’s primary tumor origin, tumor biology, tumor stage, patient performance status and comorbidities, surgical debulking and intraperitoneal chemotherapy should be considered if the benefit of therapy outweighs the risk of operation because survival curves can be extended and palliation of symptomatic malignant ascites can be achieved in select patients. In patients with peritoneal carcinomatosis who do not qualify for surgical cytoreduction but suffer from the effects of malignant ascites, intraperitoneal chemotherapy can be safely and effectively administered via laparoscopic techniques. Short operative times, short hospital stays, low complication rates and ultimately symptomatic relief are the advantages of laparoscopically administering heated intraperitoneal chemotherapy, making it not only a valuable treatment modality but also the most successful treatment modality for achieving palliative cure of malignant ascites.

China still has more than 30,000 patients of advanced schistosomiasis while new cases being reported consistently. D-dimer is a fibrin degradation product. As ascites being the dominating symptom in advanced schistosomiasis, the present study aimed to explore a prediction model of ascites with D-dimer and other clinical easy-achievable indicators. A case-control study nested in a prospective cohort was conducted in schistosomiasis-endemic area of southern China. A total of 291 patients of advanced schistosomiasis were first investigated in 2013 and further followed in 2014. Information on clinical history, physical examination, and abdominal ultrasonography, including the symptom of ascites was repeatedly collected. Result showed 44 patients having ascites. Most of the patients' ascites were confined in the kidney area with median area of 20 mm 2 . The level of plasma D-dimer and pertinent liver function indicators were measured at the initial investigation in 2013. Compared with those without ascites, cases with ascites had significantly higher levels of D-dimer (0.71±2.44 μg/L vs 0.48±2.12 μg/L, P =0.005), as well ALB (44.5 vs 46.2, g/L) and Type IV collagen (50.04 vs 44.50 μg/L). Receiver operating characteristic curve analyses indicated a moderate predictive value of D-dimer by its own area under curve (AUC) of 0.64 (95% CI: 0.54-0.73) and the cutoff value as 0.81 μg/L. Dichotomized by the cutoff level, D-dimer along with other categorical variables generated a prediction model with AUC of 0.76 (95% CI: 0.68-0.89). Risks of patients with specific characteristics in the prediction model were summarized. Our study suggests that the plasma D-dimer level is a reliable predictor for incident ascites in advanced schistosomiasis japonica patients.

Malignant ascites is a common complication in the late stages of epithelial ovarian cancer (EOC) that greatly diminishes the quality of life of patients. Malignant ascites is a known consequence of vascular dysfunction, but current approved treatments are not effective in preventing fluid accumulation. In this study, we investigated an alternative strategy of targeting macrophage functions to reverse the vascular pathology of malignant ascites using fluid from human patients and an immunocompetent murine model (ID8) of EOC that mirrors human disease by developing progressive vascular disorganization and leakiness culminating in massive ascites. We demonstrate that the macrophage content in ascites fluid from human patients and the ID8 model directly correlates with vascular permeability. To further substantiate macrophages’ role in the pathogenesis of malignant ascites, we blocked macrophage function in ID8 mice using a colony-stimulating factor 1 receptor kinase inhibitor (GW2580). Administration of GW2580 in the late stages of disease resulted in reduced infiltration of protumorigenic (M2) macrophages and dramatically decreased ascites volume. Moreover, the disorganized peritoneal vasculature became normalized and sera from GW2580-treated ascites protected against endothelial permeability. Therefore, our findings suggest that macrophage-targeted treatment may be a promising strategy toward a safe and effective means to control malignant ascites of EOC. PMID:26471360

Right ventricular hypertrophy and failure is an important step in the development of ascites syndrome (AS) in broiler chickens. Cytoplasmic calcium concentration is a major regulator of cardiac contractile function and various physiological processes in cardiac muscle cells. The purpose of this study was to measure the right ventricular pressure and investigate the precise ultrastructural location of Ca(2+) and Ca(2+)-ATPase in the right ventricular myocardium of chickens with AS induced by low ambient temperature. The results showed that the right ventricular diastolic pressure of ascitic broilers was significantly higher than that of control broilers (P < 0.01), and the maximum change ratio of right intraventricular pressure (RV +/- dp/dt(max)) of ascitic broilers was significantly lower than that of the controls (P < 0.01). Extensively increased calcium deposits were observed in the right ventricular myocardium of ascitic broilers, whereas in the age-matched control broilers, calcium deposits were much less. The Ca(2+)-ATPase reactive products were obviously found on the sarcoplasmic reticulum and mitochondrial membrane of the control right ventricular myocardium, but rarely observed in the ascitic broilers. The data suggest that in ascitic broilers there is the right ventricular diastolic dysfunction, in which the overload of intracellular calcium and the decreased Ca(2+)-ATPase activity might be the important factors.

Systemic lupus erythematous (SLE) is an auto-immune disease with multiple organ involvements that occurs mainly in young women. Literature data suggest that serositis is more frequent in late-onset SLE. However, peritoneal serositis with massive ascites is an extremely rare manifestation. We report a case of old-onset lupus peritonitis treated successfully by Hydroxychloroquine. A 77-year-old Tunisian woman was hospitalized because of massive painful ascites. Her family history did not include any autoimmune disease. She was explored 4 years prior to admission for exudative pleuritis of the right lung without any established diagnosis. Physical examination showed only massive ascites. Laboratory investigations showed leucopenia: 3100/mm3, lymphopenia: 840/mm3 and trace protein (0.03 g/24 h). Ascitic fluid contained 170 cells mm(3) (67% lymphocytes), 46 g/L protein, but no malignant cells. The main etiologies of exudative ascites were excluded. She had markedly elevated anti-nuclear antibody (ANA) titer of 1/1600 and a significantly elevated titer of antibody to double-stranded DNA (83 IU/mL) with hypo-complementemia (C3 levl was at 67 mg/dL). Antibody against the Smith antigen was also positive. Relying on these findings, the patient was diagnosed with SLE and treated with Hydroxychloroquine 200 mg daily in combination with diuretics. One month later, there was no detectable ascitic fluid and no pleural effusions. Five months later she remained free from symptoms while continuing to take chloroquine. This case was characterized by old age of onset of SLE, the extremely rare initial presentation with lupus peritonitis and massive painful ascites with dramatic response to only hydroxychloroquine treatment.

Permanent catheters for recurrent ascites-a critical and systematic review of study methodology.

Management of refractory ascites traditionally includes medical treatment with diuretics or intermittent paracentesis. Patients with recurrent ascites may benefit from the use of permanent intra-abdominal catheters with more frequent drainage without hospitalization. The objective was to systematically asses the methodology of factors and endpoints reported in studies investigating permanent catheters for recurrent ascites treatment. Using a systematic search strategy, we critically assessed the methodology when treating refractory ascites using a permanent catheter. Studies critically assessed included both retro- and prospective studies. A total of 715 unique articles were found via PubMed, The Cochrane Library and Embase. Twenty-nine studies (tunnelled catheter = 12, peritoneal ports = 6 and peritoneovenous shunts = 11) with three distinct types of permanent catheters fulfilled the inclusion criteria. Only three studies reported technical success less than 100 %. Data on complications and treatment were not available in all papers; peritonitis (48 %), cellulitis (41 %), prophylactic antibiotics (48 %) and complications to catheter insertion were difficult to distinguish from advanced co-morbidity of patients. Thirteen studies (45 %) reported some type of evaluating patient experience or functional outcome, but only three studies used validated reproducible scales when assessing outcomes. Fifteen of the 29 studies included 30 patients or less. Knowledge is limited because complications and outcomes are poorly defined. The expected increase in catheter treatment of refractory ascites necessitates comparative studies, using validated patient-related outcomes, and the reporting of unambiguous complications. A proposal of variables to include in future studies is presented.

PurposeThe aim of the study is to assess patient outcomes, complications, impact on rehospitalizations, and healthcare costs in patients with malignant ascites treated with tunneled catheters.Materials and MethodsA total of 84 patients with malignant ascites (mean age, 60 years) were treated with tunneled catheters. Patients with peritoneal carcinomatosis and malignant ascites treated with tunneled drain catheter placement over a 3-year period were studied. Overall survival from the time of ascites and catheter placement were stratified by primary cancer and analyzed using the Kaplan–Meier method. Complications were graded by the Common Terminology Criteria for Adverse Events v3.0 (CTCAE). The differences between pre-more » and post-catheter admissions, hospitalizations, and Emergency Department (ED) visits, as well as related inpatient expenses were compared using paired t tests.ResultsThere were no significant differences in gender, age, or race between different primary cancer subgroups. One patient (1 %) developed bleeding (CTCAE-2). Four patients (5 %) developed local cellulitis (CTCAE-2). Three patients (4 %) had prolonged hospital stay (between 7 and 10 days) to manage ascites-related complications such as abdominal distention, discomfort, or pain. Comparison between pre- and post-catheter hospitalizations showed significantly lower admissions (−1.4/month, p < 0.001), hospital stays (−4.2/month, p = 0.003), and ED visits (−0.9/month, p = 0.002). The pre- and post-catheter treatment health care cost was estimated using MS-DRG IPPS payment system and it demonstrated significant cost savings from decreased inpatient admissions in post-treatment period (−$9535/month, p < 0.001).ConclusionsTunneled catheter treatment of malignant ascites is safe, feasible, well tolerated, and cost effective. Tunneled catheter treatment may play an important role in improving patients’ quality of life and outcomes while controlling health care

To assess the benefit of trans-jugular intrahepatic porto-systemic shunt (TIPS) placement for refractory ascites. A retrospective observational study of all patients undergoing TIPS for refractory ascites in our hospital between 2003 and 2012. Secondary care. Cirrhotic patients with refractory ascites. We examined direct real-world (National Health Service) health related costs in the year before and after the TIPS procedure took place. Data were collected relating to the need for reintervention and hepatic encephalopathy. Data were available for 24 patients who underwent TIPS for refractory ascites (86% of eligible patients). TIPS was technically successful in all cases. Mean number of bed days in the year prior to TIPS was 30.3 and 14.3 in the year following (p=0.005). No patient had ascites at the end of the year after the TIPS with less requirement for paracentesis over the course of the year (p<0.001). Mean reduction in cost was £2759 per patient. TIPS was especially cost-effective in patients requiring between 6 and 12 drains per year with a mean saving of £9204 per patient. TIPS is both a clinically effective and economically advantageous therapeutic option for selected patients with refractory ascites.

Umbilical hernia repair is often accompanied by complications in patients with liver cirrhosis and ascites. It appears that the early elective repair of umbilical hernias in these patients is safer and can be considered for selected patients. The objective of this study is to evaluate the feasibility, safety, complications and technical aspects of sublay mesh repair of umbilical hernia in cirrhotic patients with ascites. Between October 2010 and April 2013, 70 patients with non-complicated umbilical hernia, liver cirrhosis and ascites were enrolled in this study. All patients underwent sublay mesh repair. Demographic data, preoperative variables, peri-operative course, and postoperative complications were recorded and analyzed. A total of 38 women and 32 men underwent operation at an average age 51.24 years. The patients mean MELD score was 18 (range 12-25). The mean operative time was 67.45 min and the average hospital stay was 3.8 days. 2 patients had wound infection, 3 patients developed seroma and 1 patient had an ascitic fistula. Recurrence occurred in 1 (1.4%) patient and no mortality related to the procedure. elective sublay umbilical hernia mesh repair is a safe approach and feasible technique in selected non-complicated cirrhotic patients with ascites.

Pancreatic ductal adenocarcinoma has limited treatment options. There is an urgent need for developing appropriate pre-clinical models recapitulating metastatic disease, the most common clinical scenario at presentation. Ascites accumulation occurs in up to 20–30% of patients with pancreatic cancer; this milieu represents a highly cellular research resource of metastatic peritoneal spread. In this study, we utilized pancreatic ascites/pleural effusion cancer cells to establish patient derived xenografts. Ascites/pleural effusion-patient derived xenografts were established from twelve independent cases. Xenografts were serially passed in nude mice and tissue bio-specimen banking has been established. Histopathology of emergent tumors demonstrates poorly to moderately differentiated, glandular and mucin producing tumors, mirroring morphology of primary pancreatic cancer tumors. Whole genome sequencing of six patient derived xenografts samples demonstrates common mutations and structural variations similar to those reported in primary pancreatic cancer. Xenograft tumors were dissociated to single-cells and in-vitro drug sensitivity screen assays demonstrated chemo-resistance, correlating with patient clinical scenarios, thus serving as a platform for clinically relevant translational research. Therefore, establishment of this novel ascites/pleural effusion patient derived xenograft model, with extensive histopathology and genomic characterization, opens an opportunity for the study of advanced aggressive pancreatic cancer. Characterization of metastatic disease and mechanisms of resistance to therapeutics may lead to the development of novel drug combinations. PMID:28489577

Previous research has demonstrated that physician clinical suspicion, determined without assessing fluid appearance, is not adequate to rule out spontaneous bacterial peritonitis (SBP) without fluid testing. To determine the sensitivity of physician clinical suspicion, including a bedside assessment of fluid appearance, in the detection of SBP in Emergency Department (ED) patients undergoing paracentesis. We conducted a prospective, observational study of ED patients with ascites undergoing paracentesis at three academic facilities. The enrolling physician recorded the clinical suspicion of SBP ("none," "low," "moderate," or "high"), and ascites appearance ("clear," "hazy," "cloudy," or "bloody"). SBP was defined as an absolute neutrophil count ≥ 250 cells/mm(3), or culture pathogen growth. We defined "clear" ascites fluid as negative for SBP, and "hazy," "cloudy," or "bloody" as positive. A physician clinical suspicion of "none" or "low" was considered negative for SBP, and an assessment of "moderate" or "high" was considered positive. The primary outcome measure was sensitivity of physician clinical impression and ascites appearance for SBP. There were 348 cases enrolled, with SBP diagnosed in 43 (12%). Physician clinical suspicion had a sensitivity of 42% (95% confidence interval [CI] 29-55%) for the detection of SBP. Fluid appearance had a sensitivity of 72% (95% CI 58-83%). Physician clinical impression, which included an assessment of fluid appearance, had poor sensitivity for the detection of SBP and cannot be used to exclude the diagnosis. Routine laboratory fluid analysis is indicated after ED paracentesis, even in patients considered to have a low degree of suspicion for SBP. Copyright © 2013 Elsevier Inc. All rights reserved.

Congenital chylous ascites in the neonatal period is a rare entity. Total parenteral nutrition (TPN), medium chain triglyceride (MCT)-based diet, octreotide and repeated paracentesis are regarded as appropriate medical treatment for congenital chylous ascites, and surgery is recommended when conservative therapy has failed. We present two cases in which ascites were confirmed via an abdominal sonogram and diagnostic paracentesis. In our clinical experience, rice soup combined with PN can be a safe and effective intervention.

Ascites interferes with the activity of lurbinectedin and trabectedin: Potential role of their binding to alpha 1-acid glycoprotein.

Trabectedin and its analogue lurbinectedin are effective drugs used in the treatment of ovarian cancer. Since the presence of ascites is a frequent event in advanced ovarian cancer we asked the question whether ascites could modify the activity of these compounds against ovarian cancer cells. The cytotoxicity induced by trabectedin or lurbinectedin against A2780, OVCAR-5 cell lines or primary culture of human ovarian cancer cells was compared by performing treatment in regular medium or in ascites taken from either nude mice or ovarian cancer patients. Ascites completely abolished the activity of lurbinectedin at up to 10nM (in regular medium corresponds to the IC90), strongly reduced that of trabectedin, inhibited the cellular uptake of lurbinectedin and, to a lesser extent, that of trabectedin. Since α1-acid glycoprotein (AGP) is present in ascites at relatively high concentrations, we tested if the binding of the drugs to this protein could be responsible for the reduction of their activity. Adding AGP to the medium at concentration range of those found in ascites, we reproduced the anticytotoxic effect of ascites. Erythromycin partially restored the activity of the drugs, presumably by displacing them from AGP. Equilibrium dialysis experiments showed that both drugs bind AGP, but the affinity of binding of lurbinectedin was much greater than that of trabectedin. KD values are 8±1.7 and 87±14nM for lurbinectedin and trabectedin, respectively. The studies intimate the possibility that AGP present in ascites might reduce the activity of lurbinectedin and to a lesser extent of trabectedin against ovarian cancer cells present in ascites. AGP plasma levels could influence the distribution of these drugs and thus they should be monitored in patients receiving these compounds. Copyright © 2017 Elsevier Inc. All rights reserved.

AIM: To elucidate the efficacies of tolvaptan (TLV) as a treatment for refractory ascites compared with conventional treatment. METHODS: We retrospectively enrolled 120 refractory ascites patients between January 1, 2009 and September 31, 2014. Sixty patients were treated with oral TLV at a starting dose of 3.75 mg/d in addition to sodium restriction (> 7 g/d), albumin infusion (10-20 g/wk), and standard diuretic therapy (20-60 mg/d furosemide and 25-50 mg/d spironolactone) and 60 patients with large volume paracentesis in addition to sodium restriction (less than 7 g/d), albumin infusion (10-20 g/wk), and standard diuretic therapy (20-120 mg/d furosemide and 25-150 mg/d spironolactone). Patient demographics and laboratory data, including liver function, were not matched due to the small number of patients. Continuous variables were analyzed by unpaired t-test or paired t-test. Fisher’s exact test was applied in cases comparing two nominal variables. We analyzed factors affecting clinical outcomes using receiver operating characteristic curves and multivariate regression analysis. We also used multivariate Cox’s proportional hazard regression analysis to elucidate the risk factors that contributed to the increased incidence of ascites. RESULTS: TLV was effective in 38 (63.3%) patients. The best cut-off values for urine output and reduced urine osmolality as measures of refractory ascites improvement were > 1800 mL within the first 24 h and > 30%, respectively. Multivariate regression analysis indicated that > 25% reduced urine osmolality [odds ratio (OR) = 20.7; P < 0.01] and positive hepatitis C viral antibodies (OR = 5.93; P = 0.05) were positively correlated with an improvement of refractory ascites, while the total bilirubin level per 1.0 mg/dL (OR = 0.57; P = 0.02) was negatively correlated with improvement. In comparing the TLV group and controls, only the serum sodium level was significantly lower in the TLV group (133 mEq/L vs 136 mEq/L; P = 0

Purpose: Peritoneal venous shunts (PVSs) are widely used for palliating symptoms of refractory malignant ascites and are recognized as one of the practical methods. However, reliable clinical data are insufficient because most previous reports have been small studies from single centers. We conducted a retrospective, multicenter study to evaluate the safety and efficacy of radiologically placed PVSs in patients with malignant refractory ascites. Methods: A total of 133 patients with malignant ascites refractory to medical therapies were evaluated for patient characteristics, technical success, efficacy, survival times, adverse events, and changes in laboratory data. Results: PVSs were successfully placed in allmore » patients and were effective (i.e., improvement of ascites symptoms lasting 7 days or more) in 110 (82.7%). The median duration of symptom palliation was 26 days and median survival time was 41 days. The most frequent adverse event was PVS dysfunction, which occurred in 60 (45.1%) patients, among whom function was recovered with an additional minimally invasive procedure in 9. Abnormalities in coagulation (subclinical disseminated intravascular coagulation) occurred in 37 (27.8%) patients, although only 7 (5.3%) developed clinical disseminated intravascular coagulation. Other major adverse events were gastrointestinal bleeding (9.8%), sepsis (3.8%), and acute heart failure (3.0%). PVS was least effective in patients with elevated serum creatinine, bloody ascites, or gynecologic tumor. Conclusions: Radiological PVS is a technically feasible and effective method for palliating the symptoms from refractory malignant ascites, but preoperative evaluation and monitoring the postprocedural complications are mandatory to preclude severe adverse events after PVS.« less

 Recurrent ascitic decompensation is a frequent complication of advanced alcoholic liver disease. Ascites can be controlled by transjugular intrahepatic portosystemic shunt (TIPS) implantation, but specific pre-procedural outcome predictors are not well established. Liver and spleen stiffness measurement (LSM, SSM) correlate with outcome of compensated liver disease, but data for decompensated cirrhosis disease are scarce. Therefore, the predictive value of LSM and SSM was evaluated in patients with refractory ascites treated with TIPS insertion or receiving conservative therapy.  Patients with alcoholic liver cirrhosis and recurrent or refractory ascites were stratified according to TIPS eligibility. LSM was prospectively assessed by transient elastography (TE, XL probe) and point shear wave elastography (pSWE). pSWE was also used for SSM. The primary study endpoint was transplant-free survival after 12 months. In addition, correlation of LSM and SSM with TIPS complications was analyzed.  43 patients (16 % female, age 55.5 [28.6 - 79.6] years) were recruited, n = 20 underwent TIPS and n = 23 were treated with repeated paracenteses only. 15 patients died and five underwent liver transplantation during follow-up. LSM and SSM at baseline did not predict the patients' outcome in the TIPS cohort and in patients with conservative therapy. SSM was increased in two cases with spontaneous TIPS occlusion and declined after revision.  LSM and SSM cannot be recommended for risk stratification in cirrhotic patients with refractory ascites. SSM may be useful in monitoring TIPS function during follow-up. © Georg Thieme Verlag KG Stuttgart · New York.

Ascites-induced shift along epithelial-mesenchymal spectrum in ovarian cancer cells: enhancement of their invasive behavior partly dependant on αv integrins.

At least one-third of patients with epithelial ovarian cancer (OC) present ascites at diagnosis and almost all have ascites at recurrence. The presence of ascites, which acts as a dynamic reservoir of active molecules and cellular components, correlates with the OC peritoneal metastasis and is associated with poor prognosis. Since epithelial-mesenchymal transition (EMT) is involved in different phases of OC progression, we have investigated the effect of the unique ascitic tumor microenvironment on the EMT status and the behavior of OC cells. The exposure of three OC cell lines to ascites leads to changes in cellular morphologies. Within ascites, OC cells harboring an initial intermediate epithelial phenotype are characterized by marked dislocation of epithelial markers (E-cadherin, ZO-1 staining) while OC cells initially harboring an intermediate mesenchymal phenotype strengthen their mesenchymal markers (N-cadherin, vimentin). Ascites differentially triggers a dissemination phenotype related to the initial cell features by either allowing the proliferation and the formation of spheroids and the extension of colonies for cells that present an initial epithelial intermediate phenotype, or favoring the migration of cells with a mesenchymal intermediate phenotype. In an ascitic microenvironment, a redeployment of αv integrins into cells was observed and the ascites-induced accentuation of the two different invasive phenotypes (i.e. spheroids formation or migration) was shown to involve αv integrins. Thus, ascites induces a shift toward an unstable intermediate state of the epithelial-mesenchymal spectrum and confers a more aggressive cell behavior that takes on a different pathway based on the initial epithelial-mesenchymal cell features.

Refractory ascites has a poor prognosis. Recurrent large-volume paracentesis is the current standard of care; however, it results in circulatory dysfunction and renal dysfunction, and hospitalization is commonly required. Transjugular intrahepatic portosystemic shunt placement is not an option in a substantial number of patients because of contraindications. The placement of a tunneled peritoneal drainage catheter has been shown to be effective in patients with malignant ascites. However, data in patients with nonmalignant refractory ascites are rare. We followed 24 consecutive patients in whom tunneled peritoneal drainage catheters were placed in the Endoscopy Unit at Hannover Medical School between June 2013 and December 2014. Catheters were placed in 24 patients with refractory ascites in end-stage liver disease and with a contraindication to transjugular intrahepatic portosystemic shunt placement. Placement was technically successful in all patients. The dosage of diuretics could be reduced significantly. The number of paracentesis decreased from 2.2±1 to 0 per week, although the volume of daily ascites removal remained stable (2 l). Despite frequent drainage of ascites, kidney function, serum sodium, and serum albumin remained stable. Seven adverse events occurred in six (25%) patients. Five patients listed for liver transplantation underwent successful transplantation without a negative impact. The tunneled peritoneal drainage catheter placement is a viable and effective treatment alternative in patients with refractory ascites because of end-stage liver disease, reducing diuretic intake and the need for paracentesis. The procedure avoids hyponatremia, worsening kidney function, and albumin infusions without an increased risk of spontaneous bacterial peritonitis.

Serum lipopolysaccharide-binding protein is increased in a subset of non-infected ascitic cirrhotic patients, a finding previously related to bacterial passage from the gut to the circulation without overt infection. We prospectively analysed the risk factors associated with a first episode of severe bacterial infection in 84 ascitic cirrhotics, followed up for a median of 46 weeks. The cumulative probability of such infection in patients with raised and normal lipopolysaccharide-binding protein was 32.4% and 8.0% (p=0.004), respectively. Increased lipopolysaccharide-binding protein was the only factor independently associated with severe bacterial infection in a multivariate analysis (relative risk 4.49, 95% CI 1.42-14.1). Monitoring of serum lipopolysaccharide-binding protein could, therefore, help to target cirrhotic patients with ascites for antibiotic prophylaxis.

We investigated the in vitro influence of HAF on the antibacterial activity of moxifloxacin against Escherichia coli ATCC 10798, Escherichia coli K-12, Proteus rettgeri (Sanelli), Staphylococcus aureus ATCC 25923, Staphylococcus aureus NCTC 1808 and Staphylococcus epidermidis ATCC 12228. Human ascitic fluid was obtained from 6 cirrhotic patients by paracentesis. The interaction effect was evaluated by the checkerboard technique. Our results indicate the ability of human ascitic fluid to reduce minimum inhibitory concentrations of moxifloxacin against Gram-negative bacteria, but not against Gram-positives.

The pocket ultrasound device (PUD) is a new tool that may be of use in the early detection of ascites. Abdominal ultrasound-guided paracentesis has been reported to decrease the rate of complications due to the procedure, but must be performed in a healthcare setting; this new tool may be a useful on an ambulatory basis. The aim of this study was to determine the diagnostic usefulness of the PUD in the diagnosis of ascites and the safety of guided paracentesis. We conducted a retrospective study that included adult patients suspected of having ascites and in whom an evaluation was performed with the PUD to identify it. Concordance with abdominal ultrasound (AUS) was determined with the Kappa coefficient. Sensitivity (Se), specificity (Sp) and likelihood ratios (LR) were determined and compared with physical examination, AUS, computed tomography and procurement of fluid by paracentesis. Complications resulting from the guided paracentesis were analyzed. 89 participants were included and 40 underwent a paracentesis. The PUD for ascites detection had 95.8 % Se, 81.8 % Sp, 5.27 +LR and 0.05 -LR. It had a concordance with AUS of 0.781 (p < 0.001). Technical problems during the guided paracentesis were present in only two participants (5 %) and three patients (7.5 %) developed minor complications that required no further intervention. There were no severe complications or deaths. This study suggests that the PUD is a reliable tool for ascites detection as a complement to physical examination and appears to be a safe method to perform guided paracentesis.

Hyperammonemia with or without ascites with normal synthetic liver functions after liver transplantation might indicate the presence of anastomotic stenosis of the portal or hepatic vein or the existence of a patent portosystemic shunt. The authors describe six patients, three children after split-liver transplantation and three adults after cadaver liver transplantation, who presented with hyperammonemia. Three patients had ascites. All lesions were successfully treated percutaneously; stents were placed in patients with anastomotic stenoses and coil embolization was performed in patients with patent portosystemic shunts--with either transhepatic or transjugular approaches according to the site of the abnormality. Ammonia levels returned to normal, and ascites had regressed completely for at least 3 months.

To assess the feasibility, safety and efficacy of one-stage percutaneous triple procedure including; ascites drainage, primary metallic biliary stenting, and tract embolisation with N-butyl 2-cyanoacrylate (NBCA), in treatment of patients with malignant biliary obstruction and marked ascites. This study involved 25 patients with malignant biliary obstruction and marked ascites (age range, 46-78y; mean age±SD, 65y±5) for whom endoscopic treatment failed or was unsuitable. Ascites drainage, percutaneous primary metallic biliary stenting, and tract embolisation with lipiodol/NBCA mixture were performed in a one-stage procedure. The mean±SD follow up period was 26±2weeks. The technical and clinical success rates were 96% and 88% respectively. No procedure related deaths or major complications were observed. The reported minor complications included; moderate pain and vomiting during and after balloon dilation, postprocedural cholangitis, and bile leakage in 44%, 16%, and 8% of the patients respectively. Primary stent patency was achieved in 96%. The 30-days mortality was 8%. The stent obstruction occurred in 3 (13%) of the 23 patients who survived more than 30-days. Percutaneous drainage of ascites followed immediately by primary biliary stenting, together with tract embolisation with NBCA is technically feasible, safe, and effective alternative palliative treatment for endoscopically unmanageable patients with malignant biliary obstruction and marked ascites.

2017-02-01

Image-guided percutaneous thermal ablation is increasingly utilized in the treatment of hepatic malignancies. Peripherally located hepatic tumors can be difficult to access or located adjacent to critical structures that can be injured. As a result, ablation of peripheral tumors may be avoided or may be performed too cautiously, leading to inadequate ablation coverage. In these cases, separating the tumor from adjacent critical structures can increase the efficacy and safety of procedures. Artificial ascites and artificial pneumoperitoneum are techniques that utilize fluid and gas, respectively, to insulate critical structures from the thermal ablation zone. Induction of artificial ascites and artificial pneumoperitoneum can enable complete ablation of otherwise inaccessible hepatic tumors, improve tumor visualization, minimize unintended thermal injury to surrounding organs, and reduce post-procedural pain. This pictorial essay illustrates and discusses the proper technique and clinical considerations for successful artificial ascites and pneumoperitoneum creation to facilitate safe peripheral hepatic tumor ablation.

Catumaxomab: malignant ascites: unjustified marketing authorisation.

PubMed

2010-10-01

The only treatment for malignant ascites in patients with refractory cancer is paracentesis, a procedure to relieve symptoms. Catumaxomab, a monoclonal antibody, is now authorised in the European Union for intraperitoneal administration to patients with epithelial cancers that overexpress epithelial cellular adhesion molecule (EpCAM) and provoke ascites unresponsive to chemotherapy. Clinical evaluation of catumaxomab in this setting is based on a comparative, randomised but unblinded trial including 258 patients. Patients in the catumaxomab group had four paracenteses over a 10-day period, followed by a 6-hour intraperitoneal catumaxomab infusion, while patients in the control group had a single paracentesis. Catumaxomab did not extend median survival time, which was about two months. Methodological biases rule out any conclusions as to whether catumaxomab reduced the number of paracenteses needed during this short survival period. In this trial, 80% of patients treated with catumaxomab experienced serious adverse events, versus 29% of controls, resulting in hospitalisation in respectively about 29% versus 16% of patients. Two-thirds of patients had reactions linked to intraperitoneal catumaxomab infusion. Gastrointestinal disorders were frequent, and included abdominal pain, nausea and vomiting. Catumaxomab is hepatotoxic. In addition, most patients develop anti-catumaxomab antibodies, although the clinical consequences are unclear. Catumaxomab therapy is inconvenient: it lasts 10 days and requires 4 intraperitoneal infusions that last 6 hours each and require 24-hour monitoring. In practice, catumaxomab has more harms than benefits. It is better to focus on individually tailored palliative care for these terminally ill patients.

To study the prevalence and predictive factors of spontaneous bacterial peritonitis (SBP) in patients of cirrhosis with ascites and to study the clinical characteristics and prognosis of patients with SBP. The present study was conducted on 122 cases admitted in Department of Medicine, through emergency, in Guru Gobind Singh Medical College and Hospital, Faridkot, Punjab, India. Cases of cirrhosis (irrespective of aetiology) with ascites between the ages of 18-75 years were included in this study. Ascitic fluid of every patient was aspirated under all aseptic measures, before initiation of antibiotic therapy and was sent for biochemical analysis, culture and cytological analysis. Mean age of patients enrolled was 50.30± 10.98 years. 85% were male and 15% were female. Alcohol (73.8%) was the leading cause of cirrhosis followed by HCV (37.7%) and HBV (4.9%). Of the 122 patients studied, 27 (20.4%) patients were diagnosed as having SBP and its variants. Monomicrobial Bacterascites (BA) was present in 5 patients and Culture Negative Neutrocytic Ascites (CNNA) was present in 22 patients. Escherichia coli were the most common isolated organism followed by Klebsiella. The various factors that predispose to development of SBP include low ascitic fluid protein concentration, a high level of serum bilirubin, deranged serum creatinine, high Child-Pugh score and high MELD score. Ascitic fluid analysis remains the single most important test for identifying and assessing a course of SBP. Bedside inoculation of 10-20ml of ascitic fluid into culture bottle at patient bedside will yield better results. Early diagnosis and treatment will reduce the mortality rate in these patients.

Enhanced cytogenetic damage by cyclophosphamide (CP) was observed when Ehrlich ascites tumor cells were exposed in vivo to nontoxic concentrations of caffeine. One h before i.p. injection of 5-bromodeoxyuridine adsorbed to activated charcoal Ehrlich ascites tumor-bearing mice treated i.p. with CP appear to have a dose-dependent increase in sister chromatid exchange rates and cell division delays. Caffeine increased the survival time of the Ehrlich ascites tumor-bearing mice treated with CP and markedly reduced the ascitic volume. Therefore, the in vivo antitumor effect by CP in conjunction with caffeine appears to correlate well with the in vivo synergistic effect on cytogenetic damage caused by the combined CP plus caffeine treatment.

G. lucidum total triterpenes were assessed for its apoptosis-inducing and anti-tumour activities. The ability of the total triterpenes to induce apoptosis was evaluated in Dalton's lymphoma ascites (DLA) and Ehrlich's ascites carcinoma (EAC) cell lines. Total triterpenes were found to be highly cytotoxic to DLA and EAC cell lines with IC50 values 5 ± 0.32 and 7.9 ± 0.2 µg/ml respectively. Total triterpenes induced apoptosis in both cell lines which is evident from the DNA fragmentation assay. Anti-tumour activity was accessed using DLA induced solid and EAC induced ascites tumour models in Swiss albino mice. Administration of 10, 50 and 100 mg/kg b. wt. total triterpenes showed 11.86, 27.27 and 40.57% increase in life span of animals in ascites tumour model. Treatment with 10, 50 and 100 mg/kg b. wt. total triterpenes exhibited 76.86, 85.01 and 91.03% inhibition in tumour volume and 67.96, 72.38 and 77.90% inhibition in tumour weight respectively in the solid tumour model. The study reveals the significant dose-dependent anti-tumour activity of total triterpenes in both models. Total triterpenes were more active against the solid tumour than the ascites tumour. The anti-oxidant potential and ability to induce cell-specific apoptosis could be contributing to its anti-tumour activities.

Chylous ascites is an uncommon finding which is usually associated with recent abdominal/oncologic or retroperitoneal surgery. It is not usually seen in cases of acute obstruction. A patient who had previously undergone a laparoscopy-assisted distal gastrectomy with Roux-en-Y reconstruction for early gastric cancer presented with acute abdominal pain and epigastric fullness. Computed tomography suggested small bowel obstruction due to volvulus. We were able to reduce the volvulus and close a Petersen's hernia without resecting the bowel; a large amount of chylous ascites was an incidental finding. We present a case of chylous ascites occurring in a setting of small bowel obstruction due to Petersen's hernia, 3 years after successful distal gastrectomy for early gastric cancer, with no evidence of tumor recurrence.

An 85-year-old woman was admitted to our hospital for steroid therapy for relapsing nephrotic syndrome. During hospitalization, she complained of sudden epigastric pain at night. Although there were signs of peritoneal irritation, CT showed a large amount of ascitic fluid, but no free intraperitoneal gas. Gram staining of ascitic fluid obtained by abdominal paracentesis showed Gram-negative rods, which raised a strong suspicion of gastrointestinal perforation and peritonitis. Therefore, emergency surgery was performed. Exploration of the colon showed multiple sigmoid diverticula, one of which was perforated. The patient underwent an emergency Hartmann's procedure. Imaging studies failed to reveal any evidence of gastrointestinal perforation, presenting a diagnostic challenge. However, a physician performed rapid Gram staining of ascitic fluid at night when laboratory technicians were absent, had a strong suspicion of gastrointestinal perforation, and performed emergency surgery. Gram staining is superior in rapidity, and ascitic fluid Gram staining can aid in diagnosis, suggesting that it should be actively performed. We report this case, with a review of the literature on the significance of rapid diagnosis by Gram staining.

Flood Syndrome: Spontaneous Umbilical Hernia Rupture Leaking Ascitic Fluid-A Case Report.

We report a rare case of Flood syndrome, which is a spontaneous rupture of an umbilical hernia. A 42-year-old man with decompensated hepatitis C and alcoholic cirrhosis complicated by ascites and esophageal varices presented with 1 day of ascitic fluid drainage after rupture of a preexisting umbilical hernia associated with diffuse abdominal pain and tenderness. A pigtail drain was placed in the right upper abdominal quadrant to decrease fluid drainage from the abdominal wall defect, allowing it to heal naturally. The spontaneous rupture of an umbilical hernia in our patient highlights a rare complication with high mortality rates and stresses the challenge of treatment that falls in the area between medical and surgical management.

Thymidylate synthetase from 5-fluorodeoxyuridine-resistant Ehrlich ascites carcinoma cells was purified to a state close to electrophoretical homogeneity (sp. act. = 1.3 mumoles/min/mg protein) and studied in parallel with the homogeneous preparation of the enzyme from the parental Ehrlich ascites carcinoma cells. The enzyme from the resistant cells compared to that from the parental cells showed: (i) a higher turnover number (at least 91 against 31 min-1), (ii) a higher inhibition constant (19 against 1.9 nM) for FdUMP (a tight-binding inhibitor of both enzymes), (iii) a lower activation energy at temps above 36 degrees (1.37 against 2.59 kcal/mole), and (iv) a lower inhibition constant (26 against 108 microM) for dTMP, inhibiting both enzymes competitively vs dUMP.

An Approach to Diagnosis and Endovascular Treatment of Refractory Ascites in Liver Transplant: A Pictorial Essay and Clinical Practice Algorithm.

PubMed

Pereira, Keith; Salsamendi, Jason; Fan, Ji

Recipients of liver transplant are surviving longer as both the surgical procedure and postsurgical care have improved. Despite improvements, serious complications from the procedure remain that significantly affect patient outcome and may result in retransplant. Refractory ascites is one complication, occurring in about 5.6% of transplant recipients. Management of refractory ascites after liver transplant presents a challenge to the multidisciplinary team caring for these patients. We discuss approaches to the diagnosis and treatment of refractory ascites after liver transplant, based on a literature review, with a primary focus on vascular causes. These approaches are illustrated by case examples highlighting our experiences at an academic tertiary medical center. We propose a clinical practice algorithm for optimal endovascular treatment of refractory ascites after liver transplant. The cornerstone of refractory ascites care is diagnosis and treatment of the cause. Vascular causes are not infrequently encountered and, if not treated early, are associated with graft loss and high morbidity and mortality and are major indications for retransplant. For patients with recurrent disease or graft rejection needing large volume paracentesis, the use of a transjugular intrahepatic portosystemic shunt may serve as a bridge to more definitive treatment (retransplant), although it may not be as effective for managing ascites as splenic artery embolization, arguably underused, which is emerging as a potential alternative treatment option. A multidisciplinary strategy for the diagnosis and care of patients with refractory ascites after liver transplant is crucial, with endovascular treatment playing an important role. The aim is for this document to serve as a concise and informative reference to be used by those who may care for patients with this rare yet serious diagnosis.

Although adoptive cell therapy (ACT) has demonstrated effective and remarkable clinical responses in several studies, this approach does not lead to objective clinical responses in all cases. The function of ACT is often compromised by various tumor escape mechanisms, including the accumulation of immunoregulatory cells. As a result of peritoneal metastasis in the terminal stage, malignant ascites fluid lacks effectiveness and is a poor prognostic factor for gastric cancer. The present study assessed T-cell subsets in lymphocytes derived from malignant ascites, and investigated the effects of arsenic trioxide (As 2 O 3 ) on regulatory T cells (Tregs) and ascites-derived tumor-infiltrating lymphocytes (TILs) in vitro . In this study, lymphocytes were separated from malignant ascites and T-cell subsets were detected via flow cytometry. Forkhead box P3 (FoxP3) expression was assessed by immunohistochemistry and reverse transcription-quantitative polymerase chain reaction. In addition, cytokines, including interleukin-10 (IL-10), transforming growth factor-β (TGF-β), and interferon-γ (IFN-γ), were measured by enzyme-linked immunosorbent assay (ELISA). Abundant Tregs were observed in ascites lymphocytes, which and exhibited a significantly increased frequency compared with that in the peripheral blood of patients. Furthermore, As 2 O 3 treatment significantly reduced Treg numbers and Foxp3 mRNA levels in vitro (P<0.05). IFN-γ levels in the supernatant of ascites-derived TILs were increased by As 2 O 3 , whereas IL-10 and TGF-β levels were significantly reduced (P<0.05). As 2 O 3 may induce selective depletion and inhibit immunosuppressive function of Tregs, and may enhance the cytotoxic activity of ascites-derived TILs.

Diverse proinflammatory biomarkers and oxidative stress are strongly associated with advanced epithelial ovarian cancer (EOC). Objective. To determine the behavior of markers of oxidative stress and inflammation in plasma and ascites fluid in patients with platinum-sensitive, platinum-resistant, and platinum-refractory EOC. Methods. A prospective cohort study. The colorimetric method was used to determine levels of the markers 8-isoprostanes (8-IP), lipid peroxidation products (LPO), and total antioxidant capacity (TAC) in plasma and ascites fluid; and with ELISA, the levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) were determined in patients with EOC. Results. In ascites fluid, a significant increase in 8-IP versus baseline plasma levels was found (p = 0.002). There was an important leakage of the TAC levels in ascites fluid versus baseline plasma levels (p < 0.001). The IL-6 was elevated in ascites fluid versus baseline plasma levels (p = 0.003), and there were diminished levels of TNF-α in ascites fluid versus baseline plasma levels (p = 0.001). Discussion. We hypothesize that the ascites fluid influences the behavior and dissemination of the tumor. Deregulation between oxidants, antioxidants, and the proinflammatory cytokines was found to vary among platinum-sensitive, platinum-resistant, and platinum-refractory patients. PMID:28848618

Umbilical hernia rupture with evisceration of omentum from massive ascites: a case report

2011-01-01

Introduction The incidence of hernias is increased in patients with alcoholic liver disease with ascites. To the best of our knowledge, this is the first report of an acute rise in intra-abdominal pressure from straining for stool as the cause of a ruptured umbilical hernia. Case presentation An 81-year-old Caucasian man with a history of alcoholic liver disease presented to our emergency department with an erythematous umbilical hernia and clear, yellow discharge from the umbilicus. On straining for stool, after initial clinical assessment, our patient noted a gush of fluid and evisceration of omentum from the umbilical hernia. An urgent laparotomy was performed with excision of the umbilicus and devitalized omentum. Conclusion We report the case of a patient with a history of alcoholic liver disease with ascites. Ascites causes a chronic increase in intra-abdominal pressure. A sudden increase in intra-abdominal pressure, such as coughing, vomiting, gastroscopy or, as in this case, straining for stool can cause rupture of an umbilical hernia. The presence of discoloration, ulceration or a rapid increase in size of the umbilical hernia signals impending rupture and should prompt the physician to reduce the intra-abdominal pressure.

Struma ovarii is uncommon tumor of ovary which can mimic as advanced carcinoma of ovary. Thyroid tissue is relatively frequent constituent of mature ovarian teratoma. Case of struma ovarii masquerading as cancer of ovary in a female aged 63 yrs showing complex large unilateral multilocular adnexal mass with elevated CA 125 (more than 1721 IU/L) and massive ascites mislead treating surgeons for long time. Clinicians were virtually clueless about preoperative diagnosis. Combination of ascites has been seen in one third cases but association with raised CA 125 is rare(only 8-10 cases so far). This case developed hypothyroidism one week after surgery. PMID:24783110

To explore influence of sodium restricted diet and non-sodium restricted diet on plasma rennin (PRA), angiotensin II (All), ALD, renal blood flow (RBF) and subside of ascites in patients with cirrhotic ascites. Eighty cases of hepatitis B with cirrhotic ascites were randomly divided into sodium restricted diet group and non-sodium restricted diet group. 39 cases were in non-sodium restricted diet group, taking sodium chloride 6500-8000 mg daily; 41 cases were in sodium restricted diet group, taking sodium chloride 5000 mg daily. Both groups received diuretics furosemide and spironolactone. Blood sodium, urine sodium, PRA, AII, ALD, RBF ascites subsiding were compared after treatment. In non-sodium restricted diet group, blood sodium and urine sodium increased 10 days after treatment compared with those before treatment, and compared with those of sodium restricted diet group 10 days after treatment, P <0. 01. RBF increased compared with that before treatment, and compared with that of sodium restricted diet group 10 days after treatment, P < 0. 01. Renal damage induced by low blood sodium after treatment was less in non-sodium restricted diet group than that in sodium restricted diet group, P <0. 05. Ascites disappearance upon discharge was more in sodium restricted diet group than that in non-sodium restricted diet group, P <0. 01. Time of ascites disappearance was shorter in non-sodium restricted diet group than that in sodium restricted diet group, P < 0. 01. Compared with sodium restricted diet, while using diuretics of both groups, non-sodium restricted diet can increase level of blood sodium, thus increasing excretion of urine sodium and diuretic effect. It can also decrease levels of PRA, AII and ALD, increase renal blood flow and prevent renal damage induced by low blood sodium and facilitate subsiding of ascites.

Chylous ascites occurring after abdominal surgery is rare. Despite being potentially critical, there is no definite treatment guideline because of its rarity. Here we present a case of massive chylous ascites occurring after rectal surgery which was successfully treated with an oral fat-free elemental diet (ED). A 67-year-old man underwent low anterior resection with para-aortic lymphadenectomy for advanced rectal cancer. Early postoperative course was uneventful and the patient was discharged from hospital 10 days after surgery; however, after discharge, abdominal distension rapidly developed. Abdominal computed tomography (CT) performed 3 weeks after surgery revealed massive ascites and laboratory findings showed remarkable hypoproteinemia and lymphopenia. Urgent diagnostic paracentesis showed the ascites to be a white milky fluid containing high levels of triglycerides (564 mg/dl), leading to a diagnosis of chyloperitoneum. Daily nutrition of the patient was entirely with a fat-free ED (30 kcal/kg/day of Elental(®), Ajinomoto Pharmaceutical Co. Ltd, Tokyo, Japan). After the initiation of oral Elental(®), abdominal distension, hypoproteinemia, and lymphopenia gradually improved. Abdominal CT performed 7 weeks after surgery showed no ascitic fluid in the abdomen, and thereafter a normal diet was initiated. Since then, no relapse of chyloperitoneum has been proven. As a result, the chylous ascites was successfully treated in the outpatient clinic.

Chylous ascites is an uncommon condition, which could be due to various causes. We report a case of gross chylous ascites in a patient with cirrhosis and portal vein thrombosis. It is confirmed that gross chylous ascites in a patient with cirrhosis and portal vein thrombosis heralds an ominous prognosis for the patient. Results also demonstrate that common therapeutic interventions confer minimal benefit to the patient, whose survival may be limited to a few months. The use of lymphoscintigraphy as a convenient method for diagnostic exploration of the chylous ascites is emphasized, as it does not lead to complications or adverse effects, and can be readily repeated as needed.

There are several limitations in diagnosing plasma leakage using the World Health Organization (WHO) guidelines of dengue hemorrhagic fever. We conducted a study to develop a dengue scoring system to predict pleural effusion and/or ascites using routine laboratory parameters. A prospective observational study was carried out at Cipto Mangunkusumo Hospital and Persahabatan Hospital, Jakarta, Indonesia. Dengue-infected adults admitted on the third febrile day from March, 2010 through August, 2015 were included in the study. A multivariate analysis was conducted to determine the independent diagnostic predictors of pleural effusion and/or ascites and to convert the prediction model into a scoring system. A total of 172 dengue-infected adults were enrolled in the study. Of the 172 patients, 101 (58.7 %) developed pleural effusion and/or ascites. A multivariate analysis was conducted to determine the independent diagnostic predictors of pleural effusion and/or ascites in dengue-infected adults. The predictors were scored based on the following calculations: hemoconcentration ≥15.1 % had a score of 1 (OR, 3.11; 95 % CI, 1.41-6.88), lowest albumin concentration at critical phase ≤3.49 mg/dL had a score of 1 (OR, 4.48; 95 % CI, 1.87-10.77), lowest platelet count ≤49,500/μL had a score of 1 (OR, 3.62; 95 % CI, 1.55-8.49), and elevated ratio of AST ≥2.51 had a score of 1 (OR 2.67; 95 % CI, 1.19-5.97). At a cut off of ≥ 2, the Dengue Score predicted pleural effusion and/or ascites diagnosis with positive predictive value of 79.21 % and negative predictive value of 74.63 %. This prediction model is suitable for calibration and good discrimination. We have developed a Dengue Score that could be used to identify pleural effusion and/or ascites and might be useful to stratify dengue-infected patients at risk for developing severe dengue.

Risk factor analysis for massive lymphatic ascites after laparoscopic retroperitonal lymphadenectomy in gynecologic cancers and treatment using intranodal lymphangiography with glue embolization

PubMed Central

2016-01-01

Objective To evaluate risk factors for massive lymphatic ascites after laparoscopic retroperitoneal lymphadenectomy in gynecologic cancer and the feasibility of treatments using intranodal lymphangiography (INLAG) with glue embolization. Methods A retrospective analysis of 234 patients with gynecologic cancer who received laparoscopic retroperitonal lymphadenectomy between April 2006 and November 2015 was done. In June 2014, INLAG with glue embolization was initiated to manage massive lymphatic ascites. All possible clinicopathologic factors related to massive lymphatic ascites were determined in the pre-INLAG group (n=163). Clinical courses between pre-INLAG group and post-INLAG group (n=71) were compared. Results In the pre-INLAG group (n=163), four patients (2.5%) developed massive lymphatic ascites postoperatively. Postoperative lymphatic ascites was associated with liver cirrhosis (three cirrhotic patients, p<0.001). In the post-INLAG group, one patient with massive lymphatic ascites had a congestive heart failure and first received INLAG with glue embolization. She had pelvic drain removed within 7 days after INLAG. The mean duration of pelvic drain and hospital stay decreased after the introduction of INLAG (13.2 days vs. 10.9 days, p=0.001; 15.2 days vs. 12.6 days, p=0.001). There was no evidence of recurrence after this procedure. Conclusion Underlying medical conditions related to the reduced effective circulating volume, such as liver cirrhosis and heart failure, may be associated with massive lymphatic ascites after retroperitoneal lymphadenectomy. INLAG with glue embolization can be an alternative treatment options to treat leaking lymphatic channels in patients with massive lymphatic leakage. PMID:27171674

Alpha-2A Adrenoceptor Agonist Guanfacine Restores Diuretic Efficiency in Experimental Cirrhotic Ascites: Comparison with Clonidine

2016-01-01

Background In human cirrhosis, adrenergic hyperfunction causes proximal tubular fluid retention and contributes to diuretic-resistant ascites, and clonidine, a sympatholytic drug, improves natriuresis in difficult-to-treat ascites. Aim To compare clonidine (aspecific α2-adrenoceptor agonist) to SSP-002021R (prodrug of guanfacine, specific α2A-receptor agonist), both associated with diuretics, in experimental cirrhotic ascites. Methods and Results Six groups of 12 rats were studied: controls (G1); controls receiving furosemide and potassium canrenoate (G2); rats with ascitic cirrhosis due to 14-week CCl4 treatment (G3); cirrhotic rats treated (over the 11th-14th CCl4 weeks) with furosemide and canrenoate (G4), furosemide, canrenoate and clonidine (G5), or diuretics and SSP002021R (G6). Three rats of each group had their hormonal status and renal function assessed at the end of 11th, 12th, 13th, and 14th weeks of respective treatments.Cirrhotic rats in G3 and G4 gained weight over the 12th-14th CCl4 weeks. In G4, brief increase in sodium excretion over the 11th-12th weeks preceded worsening of inulin clearance and natriuresis (diuretic resistance). In comparison with G4, the addition of clonidine (G5) or guanfacine (G6) to diuretics improved, respectively, sodium excretion over the 11th-12th CCl4 weeks, or GFR and electrolytes excretion over the 13th-14th CCl4 weeks. Natriuretic responses in G5 and G6 were accompanied by reduced catecholamine serum levels. Conclusions α2A-receptor agonists restore glomerular filtration rate and natriuresis, and delay diuretic-resistant ascites in experimental advanced cirrhosis. Clonidine ameliorates diuretic-dependent natriuresis just for a short time. PMID:27384184

Portal hypertension is regularly encountered by the general practitioner. It is defined by an elevation of the porto-systemic pressure gradient, with complications such as ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, variceal bleeding, hypersplenism, hepatopulmonary syndrome or hepatic encephalopathy occuring when a significant elevation of this gradient is reached. Cirrhosis is the primary cause of portal hypertension in industrialized countries. Symptomatic portal hypertension carries a poor prognosis. Management should be initiated rapidly, including the identification and correction of any reversible underlying condition. Liver transplantation should be considered in advanced cases.

We examined the efficacy of flavopiridol, a cyclin-dependent kinase inhibitor that is undergoing clinical trials, on primary cancer cells isolated from the ascites or pleural fluids of patients with metastatic cancers. Metastasized cancer cells were isolated from the pleural fluids (n = 20) or ascites (n = 15) of patients, most of whom were refractory to chemotherapy. These primary cancer cells were used within 2 weeks of isolation without selecting for proliferative capacities. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide viability assay was used to characterize the response of these cancer cells to commonly used chemotherapeutic agents, and their response to flavopiridol was compared with rapidly dividing cultured cell lines. The primary cancer cells displayed phenotypes that were different from established cell lines; they had very low replication rates, dividing every 1 to 2 weeks, and underwent replicative senescence within five passages. These primary tumor cells retained their resistance to chemotherapeutic drugs exhibited by the respective patients but did not show cross-resistance to other agents. However, these cancer cells showed sensitivity to flavopiridol with an average LD50 of 50 nmol/L (range, 21.5-69 nmol/L), similar to the LD50 in established cell lines. Because senescent cells also showed similar sensitivity to flavopiridol, it suggests that the mechanism of action is not dependent on the activity of cyclin-dependent kinases that regulate the progression of the cell cycle. Using cancer cells isolated from the ascites or pleural fluids, this study shows the potential of flavopiridol against cancer cells that have developed resistance to conventional chemotherapeutic agents.

Here we describe the PCA complications we observed after resection for treating a case of giant adrenocortical carcinoma and we have the brief review of the PCA complication. PMID:28149812

Immunotherapies targeting the PD-1 checkpoint pathway have recently gained regulatory approval in numerous cancer types. With the widespread use of immune checkpoint therapies, varying patterns of responses and immune-related adverse events are being observed. In this case, we highlight a patient who developed recurrent, large-volume ascites, while simultaneously having a 49% reduction in peritoneal tumor lesion size by RECIST criteria. Sampling of the fluid revealed high levels of IL-6 and IL-15. Cytology revealed no malignant cells on 4 separate paracenteses over a period of 6 weeks. Cell counts revealed that 45% of cells were lymphocytes, and further analysis was performed by fluorescence-activated cell sorting (FACS). The majority of lymphocytes were CD8 + , of which 78% were PD-1 + and 43% were HLA-DR + indicating an activated phenotype. In summary, treatment with anti-PD-1 therapy may result in pseudoprogression manifested by ascitic fluid accumulation due to the influx of activated T cells. Since worsening of ascites is typically associated with disease progression, it is important to consider the possibility of pesudoprogression in such patients undergoing therapy with immune checkpoint inhibitors.

[Study of Chinese herbal medicine in treating ascites and their mechanism in regulating lymphatic stomata].

To study the therapeutic effect of Chinese herbal medicines (CHM) in treating ascites to elucidate its mechanism in regulating the lymphatic stomata and promoting the absorption of ascites from the peritoneal cavity. Using scanning electron microscope (SEM) and computerized image processing and quantitative analysis assays, the CHM extract consisting of Atractylodes macrocephala, Salvia miltiorrhiza, Codonopsis pilosula, Alismatis orientale and Leonurus heterophyllus were studied. Intraperitoneal injection of nitric oxide (NO) supplier or CHM administration could cause the average area of lymphatic stomata obviously enlarged (P < 0.05), and the open numbers significantly increased (P < 0.01) in normal healthy mice. When L-notroarginine, a NO synthetase suppressor, was injected after CHM administration, it was found that the regulating effect of CHM on lymphatic stomata was inverted obviously, i.e. the average area and the density of lymphatic stomata were markedly reduced (P < 0.01). CHM might treat ascites through increasing the endogenous NO concentration to open the lymphatic stomata and in turn to conduct the peritoneal water through lymphatic path.

Changes in glycosylation have been associated with human cancer, but their complexity poses an analytical challenge. Ovarian cancer is a major cause of death in women because of an often late diagnosis. At least one-third of patients presents ascites fluid at diagnosis, and almost all have ascites at recurrence. Vitronectin (Vn) is a multifunctional glycoprotein that is suggested to be implicated in ovarian cancer metastasis and is found within ascites. The present study evaluated the potential of using lectin affinity for characterizing the glycosylation pattern of Vn. Human Vn was purified from 1 sample of ovarian cancer ascites or a pool of plasma samples. Consistent findings were observed with both dot blot and lectin array assays. Based on a panel of 40 lectins, the lectin array revealed discriminant patterns of lectin binding to Vn glycans. Interestingly, almost all the highlighted interactions were found to be higher with Vn from ascites relative to the plasma counterpart. Also, the lectin array was able to discriminate profiles of lectin interactions (ConA, SNA-I, PHA-E, PHA-L) between Vn samples that were not evident using dot blot, indicating its high sensitivity. The model of ConA binding during thermal unfolding of Vn confirmed the higher accessibility of mannosylated glycans in Vn from ascites as monitored by turbidimetry. Thus, this study demonstrated the usefulness of lectins and the lectin array as a glycoproteomic tool for high throughput and sensitive analysis of glycosylation patterns. Our data provide novel insights concerning Vn glycosylation patterns in clinical specimens, paving the way for further investigations regarding their functional impact and clinical interest.

Massive postoperative ascites remains a major threat that can lead to liver failure and other fatal complications, especially in patients with poor liver function. Branched-chain amino acid (BCAA) administration increases biosynthesis and secretion of albumin by hepatocytes and increases oncotic pressure by elevating blood albumin concentration, thereby decreasing peripheral edema, ascites, and pleural effusion. We randomly allocated consecutive patients undergoing major liver resection for hepatocellular carcinoma to either a group where oral BCAA administration was initiated 3 weeks before liver resection, or a non-BCAA group. The primary study endpoint was development of postoperative ascites. Overall, 39 patients were allocated to the BCAA group, while 38 were assigned to the non-BCAA group. No significant difference in the rate of refractory ascites, considered alone, was evident between the BCAA (5.1 %) and non-BCAA groups (13.2 %; p = 0.263). However, the occurrence of refractory ascites and/or pleural effusion was significantly less frequent in the BCAA group (5.1 %) than in the non-BCAA group (21.1 %; p = 0.047). Furthermore, the postoperative serum concentration of reduced-state albumin was greater immediately after liver resection in the BCAA group than in the non-BCAA group. Preoperative administration of BCAA did not significantly improve prevention of refractory ascites, but significant effectiveness in preventing ascites, pleural effusion, or both, as well as improving metabolism of albumin, was demonstrated [University Hospital Medical Information Network (UMIN) reference number 000004244].

To investigate the distribution and activation state of circulating monocytes and T-cell subsets, their contribution to tumour necrosis factor-alpha (TNFalpha) production, and their potential relationship with bacterial products of enteric origin in alcoholic cirrhosis. Peripheral blood monocytes and T-lymphocytes from 60 cirrhotic patients and 24 controls were characterized by four-color flow-cytometry after labelling of differentiation antigens and cytokines, before and after a 4-week course of norfloxacin or placebo. Monocytes from ascitic patients showed increased number, enhanced CD80 and HLA-DR surface levels, and spontaneous intracytoplasmic TNFalpha expression, when compared to non-ascitic patients and controls. Blood TNFalpha levels directly correlated with the amount of TNFalpha expressed by monocytes. In ascitic patients, there was a collapse of virgin CD4(+) and CD8(+) T-cell subsets; and, an expansion of activated CD4(+) T-cells. The above abnormalities were mainly restricted to ascitic patients with high serum levels of lypolysaccharide-binding-protein. Norfloxacin normalized the number of monocytes, reduced their activated phenotype and ability to produce TNFalpha and improved the abnormal T-cell homeostasis. In ascitic cirrhosis with high lipolysaccharide-binding-protein, monocytes are spontaneously activated to produce TNFalpha and are major contributors to the elevated serum TNFalpha. The T-cell compartment is profoundly depleted. Enteric bacterial products play a relevant role in these immune cellular abnormalities.

Spontaneous bacterial peritonitis (SBP) is a severe complication in cirrhotics with ascites. Monocyte chemotactic protien-1 (MCP-1) is a chemotactic factor for monocytes/macrophages, and it activates lymphocytes and neutrophils during infection. This study aimed to evaluate the role of MPC-1 in the pathogenesis of SBP and assess its prognostic value and correlation to disease severity. The study included ninety patients with liver cirrhosis and ascites. Patients were divided into 2 groups: Group I including 45 ascetic patients with SBP (polymorph nuclear cell count (PMN) >= 250 cell/mm3 in ascitic fluid), and Group II including 45 ascetic patients without SBP. Assessment of the severity of liver cirrhosis was done using the modified Child-Pugh and model for end stage liver disease (MELD) scores. Ascetic fluid samples were subjected to total leucocytic count and differential, albumin, protein, glucose, and serum-ascetic albumin gradient analysis Ascetic fluid levels of (MCP-1was measured by ELISA. Higher level was detected in patients with SBP as compared to those without SBP. The number of polymorph nuclear cell count (PMN) >= 250 cell/mm3 in ascitic fluid) was used as gold standard for diagnosis of SBP. The diagnosis sensitivity and specificity of MCP level test were 86.7% and 95.4% respectively at cutoff of122.5ng/ml with accuracy 91%. MCP-1 level showed positive significant correlation with TLC, PMN leucocytes and MELD score. In conclusion, ascitic fluid MCP-1 level could be a reliable test for diagnosis of SBP, and could be used as a prognostic marker due to its positive correlation with the severity of liver disease.

Patients with malignant ascites (MAs) display several symptoms, such as dyspnea, nausea, pain, and abdominal tenderness, resulting in a significant reduction in their quality of life. Tumor-associated macrophages (TAMs) play a crucial role in MA progression. Because TAMs have a tumor-promoting M2 phenotype, conversion of the M2 phenotypic function of TAMs would be promising for MA treatment. Nuclear factor-κB (NF-κB) is a master regulator of macrophage polarization. Here, we developed targeted transfer of a NF-κB decoy into TAMs by ultrasound (US)-responsive, mannose-modified liposome/NF-κB decoy complexes (Man-PEG bubble lipoplexes) in a mouse peritoneal dissemination model of Ehrlich ascites carcinoma. In addition, we investigated the effects of NF-κB decoy transfection into TAMs on MA progression and mouse survival rates. Intraperitoneal injection of Man-PEG bubble lipoplexes and US exposure transferred the NF-κB decoy into TAMs effectively. When the NF-κB decoy was delivered into TAMs by this method in the mouse peritoneal dissemination model, mRNA expression of the Th2 cytokine interleukin (IL)-10 in TAMs was decreased significantly. In contrast, mRNA levels of Th1 cytokines (IL-12, tumor necrosis factor-α, and IL-6) were increased significantly. Moreover, the expression level of vascular endothelial growth factor in ascites was suppressed significantly, and peritoneal angiogenesis showed a reduction. Furthermore, NF-κB decoy transfer into TAMs significantly decreased the ascitic volume and number of Ehrlich ascites carcinoma cells in ascites, and prolonged mouse survival. In conclusion, we transferred a NF-κB decoy efficiently by Man-PEG bubble lipoplexes with US exposure into TAMs, which may be a novel approach for MA treatment. PMID:24850474

The purposes of this study were to determine the effect of Poultry Litter Treatment (PLT) on levels of litter moisture, litter nitrogen, atmospheric ammonia, and death due to ascites. Data were collected from chicks raised in containment conditions that resembled commercial settings. The ascites death rate (5.9%) in broiler chicks on PLT-treated litter was significantly (chi 2 = 15.5, df = 1, P = 0.0001) lower than that (31.5%) in broiler chicks raised on untreated litter. Likewise, atmospheric ammonia levels in pens that had been treated with PLT were significantly (P < 0.05) lower than those in pens that received no treatment. Under the conditions of the present study, litter moisture and litter nitrogen levels were not different (P > 0.05) among treatments at any sample interval.

To clarify unknown rationalities of herbaceous compatibility of Euphorbia Pekinensis (DJ) and Glycyrrhiza glabra (GC) acting on hepatocellular carcinoma (HCC) ascites, peritoneum transcriptomics profiling of 15 subjects, including normal control (Con), HCC ascites mouse model (Mod), DJ-alone, DJ/GC-synergy and DJ/GC-antagonism treatment groups were performed on OneArray platform, followed by differentially expressed genes (DEGs) screening. DEGs between Mod and Con groups were considered as HCC ascites-related genes, and those among different drug treatment and Mod groups were identified as DJ/GC-combination-related genes. Then, an interaction network of HCC ascites-related gene-DJ/GC combination-related gene-known therapeutic target gene for ascites was constructed. Based on nodes’ degree, closeness, betweenness and k-coreness, the Frk-Arhgdib-Inpp5d-Avpr2-Aqp4 axis with highly network topological importance was demonstrated to be a candidate target of DJ/GC combination acting on HCC ascites. Importantly, both qPCR and western blot analyses verified this regulatory effects based on HCC ascites mice in vivo and M-1 collecting duct cells in vitro. Collectively, different combination designs of DJ and GC may lead to synergistic or antagonistic effects on HCC ascites partially via regulating the Frk-Arhgdib-Inpp5d-Avpr2-Aqp4 axis, implying that global gene expression profiling combined with network analysis can offer an effective way to understand pharmacological mechanisms of traditional Chinese medicine prescriptions.

Bilateral hydronephrosis secondary to urinary obstruction leads to a buildup of back pressure in the urinary tract and may lead to impairment of renal function. We present a case of a 57-year-old male with a history of alcoholic liver cirrhosis, who presented with tense ascites and acute renal failure. Bilateral hydronephrosis was seen on abdominal ultrasound. Multiple large-volume paracenteses resulted in resolution of hydronephrosis and prompt improvement in renal function. PMID:19802498

A new technique using cyanoacrylate glue is suggested for closing the transparenchymal tract following metallic endoprosthesis placement in a patient with malignant biliary obstruction complicated by ascites. With this technique, complications related to bile reflux through the transparenchymal tract would be avoided after transhepatic endoprosthesis placement in patients who have ascites. This technique would also be useful for avoiding bleeding following transhepatic portal venous puncture.

The study was conducted to determine the effects of dietary L-carnitine and coenzyme Q10 (CoQ10) supplementation on growth performance and ascites mortality of broilers. A 3 x 3 factorial arrangement was employed with three levels (0, 75 and 150 mg/kg) of L-carnitine and three levels of CoQ10 (0, 20 and 40 mg/kg) supplementation during the experiment. Five hundred and forty one-day-old Arbor Acre male broiler chicks were randomly allocated into nine groups with six replicates each. All birds were fed with the basal diets from day 1 to 7 and changed to the experimental diets from day 8. During day 15 to 21 all the birds were exposed to low ambient temperature (15-18 degrees C) to induce ascites. The results showed that under this condition, growth performance of broilers were not significantly affected by CoQ10 or L-carnitine + CoQ10 supplementation during week 0-3 and 0-6, but body weight gain (BWG) of broilers was significantly reduced by 150 mg/ kg L-carnitine during week 0-6. Packed cell volume (PCV) of broilers was significantly decreased by L-carnitine and L-carnitine + CoQ10 supplementation (P < 0.05). Erythrocyte osmotic fragility (EOF), ascites heart index (AHI) and ascites mortality of broilers were significantly decreased by L-carnitine, CoQ10 and L-carnitine + CoQ10 supplementation. Though no significant changes were observed in total antioxidative capability (T-AOC), total superoxide dismutase (T-SOD) was increased by L-carnitine, CoQ10 and L-carnitine + CoQ10 supplementation (P < 0.05). Malonaldehyde (MDA) content was significantly decreased by CoQ10 and L-carnitine + CoQ10 supplementation. The results indicate that dietary L-carnitine and CoQ10 supplementation reduce ascites mortality of broilers; the reason may be partially associated with their antioxidative effects.

Pediatric literature on spontaneous bacterial peritonitis (SBP) is limited. We evaluated the prevalence, subtypes, clinical profile, and effect on outcome of ascitic fluid infection (AFI) in children with liver disease. Children with liver disease-related ascites and subjected to paracentesis were classified as no-AFI and AFI (SBP, culture-negative neutrocytic ascites [CNNA], and monomicrobial non-neutrocytic bacterascites). Clinical and laboratory parameters, in-hospital mortality, and outcome in follow-up were noted. Two hundred sixty-two children (163 boys; age 84 [1-240] months, chronic liver disease [CLD, n = 173], non-CLD [n = 89]) were enrolled. A total of 28.6% (n = 75) had SBP/CNNA, more common in CLD than non-CLD (55/173 [31.7%] vs 20/89 [22.4%]; P = 0.1). A total of 50.6% SBP/CNNA cases were symptomatic for AFI. Gram-negative bacilli were isolated from 70% SBP cases. Twenty-five percent (18/72) CLD children with AFI had a poor hospital outcome, with INR, Child-Pugh score and gastrointestinal bleeding predicting outcome on multivariate analysis. Patients with CLD with SBP had higher in-hospital mortality (10/20 vs 5/35; P = 0.01) than those with CNNA, but similar Child-Pugh score (12[7-15] vs 11[7-14]; P = 0.1), recurrence of AFI (3/9 vs 6/24; P = 0.6) and mortality in follow-up (22.2% vs 25%; P = 0.1). Patients with CLD with SBP/CNNA had higher mortality over 1 year follow-up than no-AFI (24.2% [8/33] vs 12.2% [7/57]; P = 0.1) but the difference was not significant. A total of 28.6% children with liver disease-related ascites have SBP/CNNA; 50% are symptomatic. Patients with CLD with SBP/CNNA have a mortality of 24% over 1year follow-up. CLD with SBP is similar to CNNA except for higher in-hospital mortality.

Radiographic findings of dengue fever have not yet been clearly elucidated in relation to clinical and serological findings, despite the fact that two-fifths of the world population lives in areas where the virus is endemic. The current study is a retrospective analysis of ultrasonographic (USG) features of patients presenting with probable dengue fever during the outbreak of DF of 2006 in North India. Case records of a 169 patients with probable dengue fever were included. Ten individual sonographic parameters were reviewed vis-à-vis ascites, hepatomegaly, splenomegaly, gall bladder wall edema (GBWE), pleural effusion (right or left or both), pericardial effusion, pericholecystic collection, perinephric collection. Subjects who had GB wall thickness >3 mm as measured on ultrasound were identified as positive for GBWE. The cases were analyzed in view of their serological profile. The mean age of the subjects was 27.9 +/- 13.4 years. The mean value of the platelet count was 57.4 +/- 22.3 x 103/cmm. The most common ultrasonographic feature was ascites (126, 74.6%) followed by gall bladder wall edema (122, 72%), hepatomegaly (78, 46.2%), splenomegaly (66, 39.1%) and pericholecystic collection (63, 37.3%); 48 (28.4%) subjects demonstrated evidence of pleural effusion on the right side, while 19 (11.2%) had bilateral effusion. None of the subjects had an isolated left pleural effusion. Twenty-seven (16%) subjects reported bleeding manifestations in the form of petechiae and five (3%) developed renal dysfunction. Presence of pleural and pericardial effusions was found to be specific while ascites and GBWE were identified as highly sensitive markers for seropositive Primary DF. Ultrasonographic evidence of ascites, pleuro-pericardial effusion, and gallbladder wall edema are rapidly acquired, non-invasive markers of dengue and can be helpful before serological investigations become available. These findings may indicate severity and may herald the onset of bleeding

The balance between generation and elimination of reactive oxygen species by superoxide dismutase (SOD) is crucially involved in the pathophysiology of liver cirrhosis. Reactive oxygen species damage cells and induce inflammation/fibrosis, but also play a critical role in immune defense from pathogens. As both processes are involved in the development of liver cirrhosis and its complications, genetic variation of the SOD1 gene was investigated. Two SOD1 single nucleotide polymorphisms (rs1041740 and rs3844942) were analyzed in 49 cirrhotic patients undergoing liver transplantation. In addition, 344 cirrhotic patients with ascites were analyzed in a cohort of 521 individuals in terms of the relationship of these polymorphisms with spontaneous bacterial peritonitis (SBP). Although rs3844942 showed no associations with complications of cirrhosis, we observed a significant association between rs1041740 and the presence of ascites and SBP in the discovery cohort of patients with cirrhosis. Importantly, the association with SBP was not confirmed in the validation cohort of patients with ascites. By contrast, a trend toward lower SBP rates was observed in carriers of rs1041740. In this cohort, rs1041740 was not associated with survival. These data suggest a complex role of SOD1 in different processes leading to complications of liver cirrhosis. rs1041740 might be associated with the development of ascites and possibly plays a role in SBP once ascites has developed.

A 40-year-old woman was admitted due to an urticarial rash that was attributed to recent onset of methimazole treatment for a diagnosis of Grave's disease. The patient had no prior significant medical history and used no medications, including over-the-counter or herbal medications. Her sister had Grave's disease. On admission, the patient received corticosteroids with improvement in her rash. On the second day of the hospitalization, the patient complained of abdominal discomfort. Abdominal ultrasound revealed a large amount of new onset ascites. Peritoneal tap yielded a milky fluid with high triglyceride level (12.2 mmol/L or 1080 mg/dL), consistent with chylous ascites. After discontinuation of the methimazole, the ascites disappeared. The patient later underwent therapeutic thyroidectomy, after which all features of thyrotoxicosis had improved. PMID:26366308

A total of 336 one-day-old male broiler chickens were allocated to 4 experimental groups with 4 replicates of 21 birds each under STC. In addition, the same grouping with another 336 birds was used for CTC. Under CTC, the birds were exposed to cold temperatures for induction of ascites. Experimental groups were defined by the inclusion of 0 (control), 5, 10 or 15 g/kg garlic bulbs in the diets under both STC and CTC. Growth performance, systolic blood pressure (as a measure of systemic arterial blood pressure), physiological and biochemical parameters, as well as ascites indices (right ventricle [ RV: ], total ventricle [ TV: ] weights, and RV/TV: ) were evaluated. Systolic blood pressure was determined using an indirect method with a sphygmomanometer, a pediatric cuff, and a Doppler device. The final body weight decreased quadratically (P = 0.003), with increasing garlic bulb levels in the diets under STC. The feed conversion ratio showed no significant differences among all groups under both STC and CTC. No significant differences were observed in total mortality and ascites-related mortality in all groups under STC, although total mortality (L: P = 0.01; Q: P = 0.001) and ascites-related mortality (L: P = 0.007; Q: P = 0.001) were significantly different among the diets under CTC. Under STC, the systolic blood pressure, packed cell volume, hemoglobin, RV, TV, and RV/TV did not vary significantly among the diets. However, red blood cell count and erythrocyte osmotic fragility decreased linearly (P < 0.005) with increasing garlic bulb levels in the diets under STC. Under CTC, the systolic blood pressure, packed cell volume, red blood cell count, and erythrocyte osmotic fragility decreased

To evaluate the efficacy of intraperitoneal vincristine administration into ascitic sarcoma-180 bearing mice as a model of human malignant ascites regarding various peritoneal/retroperitoneal sarcomatosis, and to evaluate the flowcytometric telomerase reverse transcriptase expression for the diagnostic and prognostic purposes. Present study included disease induction by intraperitoneal homologous ascitic sarcoma-180 transplantation followed by in vivo intraperitoneal drug administration to study mitotic index, flowcytometric cell cycle and telomerase reverse transcriptase expression pattern, erythrosin-B dye exclusion study for malignant cell viability assessment. Besides, in vitro malignant ascite culture in presence and absence of vincristine sulfate and survival study were also taken into consideration. Intraperitoneal vincristine administration (concentration 0.5 mg/kg body weight) significantly diminished the mitotic index in diseased subjects in comparison to untreated control subjects. Treated group of animals showed increased life span and median survival time. Cell viability assessment during the course of drug administration also revealed gradual depression on cell viability over time. Flowcytometric cell cycle analysis showed a good prognostic feature of chemotherapeutic administration schedule by representing high G2/M phase blocked cells along with reduced telomerase reverse transcriptase positive cells in treated animals. We conclude that long term administration of vincristine sulfate in small doses could be a good pharmacological intervention in case of malignant peritoneal ascites due to sarcomatosis as it indirectly reduced the level of telomerase reverse transcriptase expression in malignant cells by directly regulating cell cycle and simultaneously increased the life expectancy of the diseased subjects.

To evaluate the effect of the heat-sink phenomenon induced by artificial ascites on the size of the ablation zone during percutaneous radiofrequency (RF) ablation of the hepatic subcapsular area in an in vivo rabbit model. A total of 21 percutaneous rabbit liver RF ablations were performed with and without artificial ascites (5% dextrose aqueous solution). The rabbits were divided into three groups: a) control group (C, n = 7); b) room temperature ascites group (R, n = 7); and c) warmed ascites group (W, n = 7). The tip of a 1 cm, internally cooled electrode was placed on the subcapsular region of the hepatic dome via ultrasound guidance, and ablation was continued for 6 min. Changes in temperature of the ascites were monitored during the ablation. The size of the ablation zones of the excised livers and immediate complications rates were compared statistically between the groups (Mann-Whitney U test, Kruskal-Wallis test, linear-by-linear association, p = 0.05). One rabbit from the "W" group expired during the procedure. In all groups, the ascites temperatures approached their respective body temperatures as the ablations continued; however, a significant difference in ascites temperature was found between groups "W" and "R" throughout the procedures (39.2+/-0.4 degrees C in group W and 33.4+/-4.3 degrees C in group R at 6 min, p = 0.003). No significant difference was found between the size of the ablation zones (782.4+/-237.3 mL in group C, 1,172.0+/-468.9 mL in group R, and 1,030.6+/-665.1 mL in group W, p = 0.170) for the excised liver specimens. Diaphragmatic injury was identified in three of seven cases (42.9%) upon visual inspection of group "C" rabbits (p = 0.030). Artificial ascites are not likely to cause a significant heat-sink phenomenon in the percutaneous RF ablation of the hepatic subcapsular region.

A hypothesis was tested that providing the breeder hens with exogenous thyroxine (T(4)) would help their offspring to better survive the ascites-inducing condition during the growing period. In total, 132 broiler breeder hens were randomly assigned to one of 3 treatments: control (CON), hypothyroid [HYPO; 6-N-propyl-2-thiouracil (PTU)-treated], and hyperthyroid (HYPER; T(4)-treated). The hens were artificially inseminated, and the hatching eggs (n = 1,320) were incubated. No eggs in the HYPO group hatched. The 1-d-old male chicks (n = 288) from other groups were reared for 42 d under standard or low ambient temperature to induce ascites. Blood samples were drawn from the hens, embryos, and broilers for determination of T(4) and triiodothyronine (T(3)). The hematocrit was also determined in broilers. The PTU-treated hens had an increased BW along with lower plasma T(3) and T(4) concentrations. Plasma T(4) was higher in the HYPER hens compared with CON hens, but T(3) concentration was not different between these groups. The fertility rate was not affected by either hypo- or hyperthyroidism. The embryos in the HYPO group had lower plasma T(3) and T(4) concentrations at d 18 of embryonic development and internal pipping. Higher plasma T(4) was recorded in the HYPER birds at internal pipping, although plasma T(3) concentration was not affected at this stage. Maternal hyperthyroidism decreased the overall incidence of ascites in the cold-exposed chickens (10.0 vs. 33.4% for HYPER and CON groups, respectively). Although the effect of maternal PTU or T(4) treatment on plasma thyroid hormones and on the right ventricle-to-total ventricular weight ratio in the broilers was not significant, the cold-exposed healthy CON chicks showed higher hematocrit values, compared with the HYPER birds. It was concluded that maternal hyperthyroidism could decrease the incidence of cold-induced ascites in broiler chickens; however, probable causal mechanisms remain to be elucidated.

The excess and deficit of serotonin can be the cause of somatic and mental disorders. The aim of this study was to evaluate serotonin levels in blood and ascitic fluid as well as excretion of 5-hydroxyindoleacetic acid (5-HIAA) in urine in patients with hepatic encephalopathy (HE). The study included 75 alcoholic cirrhotic patients divided into 3 groups (HE1, HE2, HE3), 25 patients each, with grade 1, 2 and 3 of hepatic encephalopathy according to West-Haven classification. The control group (C) included 25 clinically healthy volunteers. Venous blood and ascitic fluid were collected in fasting. On the same day a 24-hour urine collection was performed. Immunoenzymatic method was used to determine the serotonin level in serum and ascitic fluid, and 5-HIAA in urine (IBL-RE-59121, RE-59131). In the control group, mean serum serotonin level (ng/ml) was 155.5 ± 38.1 and in the 3 study groups: HE1 - 175.2 ± 32.4 (NS), HE2 - 137.2 ± 28.6 (NS), HE3 - 108.3 ± 46.3 (p<0.001). Serotonin concentration in ascitic fluid was on the average about 25% of its level in serum. The excretion of 5-HIAA in urine (mg/24h) in all groups, was: C - 5.9 ± 2.1, HE1 - 5.8 ± 1.8 (NS), HE2 - 4.8 ± 1.2(NS), HE3 - 4.3 ± 1.3 (p<0.05). The results of our study indicate that serum and ascitic fluid level of serotonin and urine excretion of 5-HIAA depends on the grade of hepatic encephalopathy. In patients with severe hepatic encephalopathy serotonin concentration in blood is decreased which can affect some clinical manifestation of this disease.

Small interfering RNA (siRNA) offers a great potential for the treatment of various diseases and disorders. Nevertheless, inefficient in vivo siRNA delivery hampers its translation into the clinic. While numerous successful in vitro siRNA delivery stories exist in reduced-protein conditions, most studies so far overlook the influence of the biological fluids present in the in vivo environment. In this study, we compared the transfection efficiency of liposomal formulations in Opti-MEM (low protein content, routinely used for in vitro screening) and human undiluted ascites fluid obtained from a peritoneal carcinomatosis patient (high protein content, representing the in vivo situation). In Opti-MEM, all formulations are biologically active. In ascites fluid, however, the biological activity of all lipoplexes is lost except for lipofectamine RNAiMAX. The drop in transfection efficiency was not correlated to the physicochemical properties of the nanoparticles, such as premature siRNA release and aggregation of the nanoparticles in the human ascites fluid. Remarkably, however, all of the formulations except for lipofectamine RNAiMAX lost their ability to be taken up by cells following incubation in ascites fluid. To take into account the possible effects of a protein corona formed around the nanoparticles, we recommend always using undiluted biological fluids for the in vitro optimization of nanosized siRNA formulations next to conventional screening in low-protein content media. This should tighten the gap between in vitro and in vivo performance of nanoparticles and ensure the optimal selection of nanoparticles for further in vivo studies.

Mortality in spontaneous bacterial peritonitis (SBP) decreased significantly from 90% in 1970 to 10-30% today, but SBP still remains a complication with a poor prognosis. Although there are new preventive measures, such as early diagnosis and treatment with albumin, the introduction of new antibiotics, the prognosis of patients with decompensated cirrhosis and SBP remains poor, with a mortality rate of 20-40%. The installation of an episode of spontaneous bacterial peritonitis reduces the survival rate at 1 year to 30% and to 20% at 2 years. In this context, the identification of patients with increased risk of death is extremely important in order to improve prognosis. The prospective study included 153 patients with cirrhosis admitted to the Institute of Gastroenterology and Hepatology Iaşi from 1 January to 31 December 2010, reevaluated during 2 years. Criteria for the diagnosis of SBP were the presence of a number > 250 PMN / mmc. The presence of ascites and/or upper gastrointestinal bleeding (UGB) marks the decompensated cirrhosis. To assess the severity of cirrhosis, there were used Child-Pugh and MELD scores. Diagnostic paracentesis and ascites fluid cultures were performed in all hospitalized patients with ascites and also in case of signs and symptoms of SBP, before and after antibiotic treatment. Lack of response to empirical therapy was considered in those cases with a decrease in the number of neutrophils < 25% from baseline. Identification of patients with increased risk of death is extremely important to improve prognosis. In peripheral leukocytosis and in the ascites fluid, low hemoglobin can be considered predictors of mortality in patients with PBS. Child-Pugh score, increased levels of bilirubin and creatinine and hyponatremia are independent risk factors of mortality in patients with SBP. Bacteremia and lack of therapeutic response are independent risk factors of mortality associated with SBP. Recent history of variceal bleeding, severity of

Midodrine is an α-agonist prodrug of desglymidodrine used for the management of hypotension, and can also be used for hepatorenal syndrome and cirrhotic patients with tense ascites. The objective of the present work was to study the clinical pharmacokinetic parameters of midodrine and its active metabolite desglymidodrine in cirrhotic patients with tense ascites, which may help in dose selection and improve treatment outcome. This was a prospective, open-label, single-dose, parallel-group study. At first, a pilot study was performed on one healthy volunteer by taking serial blood samples at scheduled time intervals to validate the method of analysis and sampling times. The full study was then conducted by selecting 12 cirrhotic patients with tense ascites in one group and taking nine blood samples. We also selected five healthy volunteers as the control group and took 11 blood samples. Statistically significant differences were observed between the healthy volunteer group and the patients group in the area under the concentration versus time curve (AUC0-t) and maximum plasma concentration (Cmax) values of midodrine and desglymidodrine. Based on the results of the pharmacokinetic analysis, the patient group was further subdivided into those receiving the interacting drug ranitidine (five patients) and those not receiving the interacting drug (seven patients). Pharmacokinetic parameters of midodrine can differ significantly in cirrhotic patients with tense ascites from those in healthy individuals. Drug monitoring, dose adjustments, and drug-drug interactions should all be considered during therapy in this vulnerable patient group.

Umbilical hernias are common in cirrhotics, yet, their management poses several challenges. The objective of this paper was to evaluate the indications, selection criteria, and technical aspects of umbilical hernia repair in patients with cirrhosis and ascites. An extensive review of the literature since 1980 was performed. A survey was also conducted to obtain expert consensus to supplement any available conclusions from the literature. Nineteen surgeons (45%) responded to the survey. For asymptomatic hernias, all would consider hernia repair in Child's A cirrhosis, but not in more advanced disease, whereas the vast majority would consider the repair of complicated hernias. This seems to reflect the respondents' higher estimates of morbidity and mortality with more advanced liver disease. However, because the recent literature demonstrates much lower morbidity and mortality than in the past, many authors now advocate early elective repair. In addition, uncontrolled ascites appear to be strongly predictive of hernia recurrence (relative risk [RR] 8.5; 95% confidence interval [CI] 2.7-26.9). While acknowledging the limitations of this study, it appears that the early repair of umbilical hernias in patients with cirrhosis and ascites is safer than it was in the past and can be considered for selected patients. This may avoid increased morbidity and mortality associated with urgent repair later on. The control of ascites is critical to a successful outcome. Urgent repair of umbilical hernia in cirrhotic patients is indicated when complications develop.

An experiment was conducted to evaluate the effects of dietary glutamine (Gln) and arginine (Arg) supplementation on performance, intestinal morphology and ascites mortality in broilers. A total of 675 day old chicks were randomly allocated to 9 experimental groups in a 3×3 factorial arrangement based on a completely randomized design with 5 replicates of 15 chicks. Three levels of dietary Gln (0, 0.5 and 1%) and Arg (100, 130% and 160% of Ross recommendation) supplementation were used in ascites inducing condition (15±1 ˚C) from 7 to 42 days of age. Dietary supplementation of Gln increased body weight gain (BWG) during grower, finisher and total periods (P<0.05) and increased feed intake during total period. Ascites mortality was decreased by Gln supplementation (P<0.05). Gln supplementation increased the villus height (VH) and crypt depth (CD) in duodenum and jejunum, and decreased the muscular layer in jejunum and ileum segments (P<0.05). Arg supplementation decreased CD in duodenum and jejunum and increased ileum villus width (VW), villus height /crypt depth ratio (VH/CD) in duodenum and jejunum and also muscular layer in duodenum, jejunum and ileum (P<0.05). Both Gln and Arg increased the goblet cell number (GCN) in duodenum whereas Gln supplementation decreased GCN in jejunum and ileum (P<0.05). The Gln×Arg interaction were observed for VH, VW, CD, VH/CD, muscular and serous layer thickness. It was concluded that dietary 0.5% Gln along with 130% Arg of Ross requirement, improve the intestinal morphology and performance and hence decrease the ascites mortality in broiler chickens with cold induced ascites.

We report our experience of managing an 18-month-old boy in whom a giant omental cyst of 4.6 kg, which constituted 42% of his pre-operative weight, masqueraded as massive ascites. Pre-operative diagnosis and early surgical intervention were facilitated by inter-disciplinary collaboration, ultrasonography and radiological contrast studies. The differential diagnoses and treatment options of omental and mesenteric cysts are discussed. The importance of ultrasonography as an initial imaging tool for arriving at the correct diagnosis in a child with ascites of obscure aetiology is emphasized.

Diagnosis of abdominal tuberculosis (TB) from ascitic fluid samples using routinely available diagnostic methods is challenging due to its paucibacillary nature. Although performance of Xpert MTB/RIF assay has been evaluated extensively on pulmonary samples, its performance on extrapulmonary samples is still under evaluation. The objective of this study was to find out the performance of Xpert MTB/RIF on ascitic fluid samples obtained from suspected cases of abdominal TB. Performance was compared with Mycobacterium growth indicator tube-960 (MGIT-960) culture and in-house multiplex polymerase chain reaction (PCR). The latter detects and differentiates Mycobacterium tuberculosis and nontuberculous mycobacteria simultaneously. Sixty-seven patients suspected of probable/possible abdominal TB were included in this observational, prospective study. All samples were tested by Ziehl-Neelsen staining, MGIT-960 culture, in-house multiplex PCR, and Xpert MTB/RIF assay. All 67 samples were smear negative. Seventeen (25.4%) were MGIT-960 culture positive while 12 (17.9%) were detected positive by the Xpert MTB/RIF assay and 9 (13.4%) by in-house multiplex PCR. Sensitivity and specificity of the Xpert MTB/RIF assay compared with the MGIT-960 culture were 70.6% (95%, confidence interval [CI]: 44.1-89.7) and 100% (95%, CI: 92.8-100) and that of in-house multiplex PCR were 52.9% (95%, CI: 30.9-73.8) and 100% (95%, CI: 92.8-100), respectively. Diagnostic yield of Xpert MTB/RIF assay on ascitic fluid samples was lower than MGIT-960 culture. We thus emphasize on the need for urgent discovery of new biomarkers for paucibacillary TB.

Thioredoxin reductase (TrxR) is a target for cancer therapy and the anticancer mechanism of cisplatin involves TrxR inhibition. We hypothesize that the anticancer drug nedaplatin (NDP), an analogue of cisplatin and a second-generation platinum complex, also targets TrxR. Furthermore, we investigate whether the therapeutic efficacy of NDP can be enhanced by simultaneous modulation of 1) TrxR, via NDP, and 2) glutathione (GSH), via the GSH synthesis inhibitor buthionine sulfoximine (BSO). Mice bearing ascitic hepatoma 22 (H22) cells were treated with NDP alone or NDP plus BSO. TrxR activity of H22 cells was inhibited by NDP in a dose-dependent manner. Amore » high correlation between the inhibition of TrxR activity at 6 h and the inhibition of ascitic fluid volume at 72 h was established (r = 0.978, p < 0.01). As an adaptive response, the viable ascitic cancer cells after NDP treatment displayed an enlarged cell phenotype, assembled with several-fold more antioxidant enzymes and GSH-predominant non-protein free thiols. This adaptive response was largely eliminated when BSO was co-administered with NDP, leading to the decimation of the H22 cell population without enhancing renal toxicity, since at this dose, NDP did not inhibit renal TrxR activity. In conclusion, the pharmacological effect of NDP involves TrxR inhibition, and the adaptive response of NDP-treated ascitic H22 cells can be efficiently counteracted by BSO. Simultaneous modulation of TrxR and GSH on ascitic H22 cells using NDP plus BSO greatly enhances therapeutic efficacy as compared with the single modulation of TrxR using NDP alone. -- Highlights: ► Nedaplatin at a pharmacological dose inhibits TrxR in cancer cells but not in kidney. ► The nedaplatin-treated cancer cells exhibit adaptive response. ► Buthionine sulfoximine inhibits glutathione in both cancer cells and kidney. ► Buthionine sulfoximine counteracts the adaptive response to the nedaplatin treatment. ► Buthionine sulfoximine does

A 53-year-old man with Crohn's disease treated with adalimumab was hospitalised with abdominal pain, fatigue, fever and chills. CT scan of the abdomen showed chronic thickening of the terminal ileum and cecum and new-onset ascites. Further studies revealed weakly positive urine and serum histoplasma antigen. Laparoscopy revealed metastatic caking of the omentum and abdominal wall; peritoneal biopsy demonstrated organisms morphologically consistent with Histoplasma capsulatum No dissemination outside of the peritoneal cavity was evident. The patient completed 2 weeks of liposomal amphotericin B followed by oral itraconazole for 1 year. Adalimumab therapy was held for 10 weeks, then restarted. Presenting symptoms resolved following initiation of antifungal therapy. Follow-up MRI of his abdomen demonstrated resolution of ascites. To our knowledge, this is the first reported case of histoplasmosis presenting as peritonitis in a patient with Crohn's disease receiving antitumour necrosis factor-alpha (TNF-α) therapy. Many clinicians are aware that patients receiving anti-TNF-α therapy are at increased risk for histoplasmosis, but may fail to consider the diagnosis in the absence of lung involvement. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Refractory ascites in liver-cirrhosis is associated with a poor prognosis. We performed a prospective study to investigate whether aggressive nutritional-support could improve outcomes in cirrhotic patients. Cirrhotic patients undergoing serial large-volume paracentesis for refractory-ascites were enrolled and randomized into three groups. Group A received post-paracentesis intravenous nutritional-support in addition to a balanced oral diet and a late-evening protein snack, group B received the same oral nutritional-protocol as the first group but without parenteral support, and group C (the control group) received a low-sodium or sodium-free diet. Clinical, anthropometric and laboratory nutritional parameters and biochemical tests of liver and renal function were reported for 12 months of follow-up. We enrolled 120 patients, who were randomized into three groups of equal size. Patients on the nutritional-protocol showed better preservation of clinical, anthropometric and laboratory nutritional parameters that were associated with decreased deterioration of liver function compared with patients on the low-sodium or sodium-free diet (group C). Groups A and B had lower morbidity and mortality rates than the control group (C). Mortality rates were significantly better in patients who were treated with parenteral-nutritional-support than for the other two groups. In patients who were on the nutritional-protocol, there was a reduction in the requirement of taps for the treatment of refractory ascites. Post-paracentesis parenteral-nutritional-support with a balanced oral diet and an evening protein snack appears to be the best care protocol for patients with liver-cirrhosis that has been complicated by refractory-ascites. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

To evaluate the clinical efficiency of tumor-infiltrating lymphocytes (TILs) compared to cisplatin for malignant pleural effusion and ascites through intrapleural and intraperitoneal infusion. Thirteen patients with malignant pleural effusion and ascites were divided into a TIL-treated group and a cisplatin-treated group. Patients were given TILs or cisplatin, through intrapleural and intraperitoneal infusion respectively, after drainage of the malignant serous effusion by thoracentesis or abdominocentesis. The overall response rate and disease control rate of the TIL-treated group (33.33% and 83.33%) were higher than that of the cisplatin-treated group (28.57% and 71.43%). The progression-free survival for the TIL-treated group was significantly longer (p=0.002) and better than that of the cisplatin-treated group (66.67% vs. 28.57%). Quality of life apparently improved in the TIL-treated group and was clearly higher than that in the cisplatin-treated group. The use of TILs has a better clinical efficiency for malignant pleural effusion and ascites than cisplatin through intrapleural and intraperitoneal infusion without severe adverse effects.

AIM: To investigate the benefits of probiotics treatment in septic rats. METHODS: The septic rats were induced by cecal ligation and puncture. The animals of control, septic model and probiotics treated groups were treated with vehicle and mixed probiotics, respectively. The mixture of probiotics included Bifidobacterium longum, Lactobacillus bulgaricus and Streptococcus thermophilus. We observed the survival of septic rats using different amounts of mixed probiotics. We also detected the bacterial population in ascites and blood of experimental sepsis using cultivation and real-time polymerase chain reaction. The severity of mucosal inflammation in colonic tissues was determined. RESULTS: Probiotics treatment improved survival of the rats significantly and this effect was dose dependent. The survival rate was 30% for vehicle-treated septic model group. However, 1 and 1/4 doses of probiotics treatment increased survival rate significantly compared with septic model group (80% and 55% vs 30%, P < 0.05). The total viable counts of bacteria in ascites decreased significantly in probiotics treated group compared with septic model group (5.20 ± 0.57 vs 9.81 ± 0.67, P < 0.05). The total positive rate of hemoculture decreased significantly in probiotics treated group compared with septic model group (33.3% vs 100.0%, P < 0.05). The population of Escherichia coli and Staphylococcus aureus in ascites of probiotics treated group were decreased significantly compared with that of septic model group (3.93 ± 0.73 vs 8.80 ± 0.83, P < 0.05; 2.80 ± 1.04 vs 5.39 ± 1.21, P < 0.05). With probiotics treatment, there was a decrease in the scores of inflammatory cell infiltration into the intestinal mucosa in septic animals (1.50 ± 0.25 vs 2.88 ± 0.14, P < 0.01). CONCLUSION: Escherichia coli and Staphylococcus aureus may be primary pathogens in septic rats. Probiotics improve survival of septic rats by suppressing these conditioned pathogens. PMID:23840152

Differential response of human melanoma and Ehrlich ascites cells in vitro to the ribosome-inactivating protein luffin.

The cytotoxicity and inhibitory effect on proliferation of the type 1 ribosome-inactivating protein luffin purified from the seeds of Luffa aegyptiaca were investigated both in human metastatic melanoma cells and in murine Ehrlich ascites tumour cells. Results indicate that luffin from the seeds of Luffa aegyptiaca is cytotoxic to the cell lines tested, with approximately 10 times greater potency in Ehrlich cells. Luffin was found to induce an increase in cytosolic oligonucleosome-bound DNA in both melanoma and Ehrlich ascites tumour cells, the level of DNA fragmentation in the former cell line being higher than in the latter. Experiments with melanoma cells indicate that an increase in cytosolic nucleosomes could be supportive of apoptosis as the type of cell death induced by luffin.

Yellowtail ascites virus (YAV) is an aquabirnavirus that causes ascites in yellowtail, a fish often used in sushi. Segment A of the YAV genome codes for a polyprotein (pVP2-VP4-VP3), where processing by its own VP4 protease yields the capsid protein precursor pVP2, the ribonucleoprotein-forming VP3, and free VP4. VP4 protease utilizes the rarely observed serine-lysine catalytic dyad mechanism. Here we have confirmed the existence of an internal cleavage site, preceding the VP4/VP3 cleavage site. The resulting C-terminally truncated enzyme (ending at Ala716) is active, as shown by a trans full-length VP4 cleavage assay and a fluorometric peptide cleavage assay. We present a crystal structure of a native active site YAV VP4 with the internal cleavage site trapped as trans product complexes and trans acyl-enzyme complexes. The acyl-enzyme complexes confirm directly the role of Ser633 as the nucleophile. A crystal structure of the lysine general base mutant (K674A) reveals the acyl-enzyme and empty binding site states of VP4, which allows for the observation of structural changes upon substrate or product binding. These snapshots of three different stages in the VP4 protease reaction mechanism will aid in the design of anti-birnavirus compounds, provide insight into previous site-directed mutagenesis results, and contribute to understanding of the serine-lysine dyad protease mechanism. In addition, we have discovered that this protease contains a channel that leads from the enzyme surface (adjacent to the substrate binding groove) to the active site and the deacylating water.

This study reports the biological properties of LQFM030 in vivo, a molecular simplification of the compound nutlin-1. Ehrlich ascites tumor (EAT)-bearing mice were treated intraperitoneally with LQFM030 (50, 75 or 150mg/kg) for 10days to determine changes in ascites tumor volume, body weight, cytotoxicity and angiogenesis. Moreover, flow cytometric expression of p53 and p21 proteins and caspase-3/7, -8 and -9 activation were investigated in EAT cells from mice treated. Acute oral systemic toxicity potential of LQFM030 in mice was also investigated using an alternative method. Treatment of EAT-bearing mice with LQFM030 resulted in a marked decline in tumor cell proliferation and the vascular endothelial growth factor (VEGF) levels along with enhanced survival of the mice. Apoptotic tumor cell death was detected through p53 and p21 modulation and increase of caspase-3/7, -8 and -9 activity. LQFM030 also showed orally well tolerated, being classified in the UN GHS category 5 (LD 50 >2000-5000mg/Kg). LQFM030 seems to be a promising antitumor candidate for combinatory therapy with typical cytotoxic compounds, reducing the toxicity burden while allowing a superior anticancer activity. Moreover, these data also open new perspectives for LQFM030 as an antiangiogenic agent for treatment of diseases involving VEGF overexpression. Copyright © 2017. Published by Elsevier Inc.

Albumin constitutes approximately one half of the proteins in the plasma and plays a pivotal role in modulating the distribution of fluid between body compartments. Hence it is commonly employed in cirrhotic patients in association with diuretics for the treatment of ascites. Nevertheless, its usefulness is controversial in this condition and well-stated only in some circumstances. The item of safety of the drug appears to be convincing due to the accurate cautions in the course of its preparation. Side effects are described in literature only as sporadic events. Indeed, albumin administration is effective to prevent the circulatory dysfunctions after large-volume paracentesis and renal failure and after Spontaneous Bacterial Peritonitis (SBP). Finally albumin represents, associated with vasoconstrictors, the therapeutic gold standard for the hepatorenal-syndrome (HRS). Physiopathological bases of the therapeutic use of albumin in hepatic cirrhosis consist in both hypoalbuminemia and portal hypertension consequences. In fact, cirrhotic patient with ascites, in spite of hydrosaline retention, shows an effective hypovolemia with peripheral arterial vasodilatation and increase in heart rate. Therefore the effectiveness of albumin administration in the treatment of ascites is due to its plasma volume expander property as well as its efficacy in restoring plasmatic oncotic pressure. Trials are in progress in order to define the effectiveness of the prolonged home-administration of human albumin in the treatment and prevention of ascites. Finally, it has been recently demonstrated that the binding, transport and detoxification capacities of human albumin are severely reduced in cirrhotics and this impairment correlates with the degree of liver failure. Therefore, the next challenge will be to determine whether the alterations of non-oncotic properties of albumin are able to forecast mortality in cirrhotics with ascites and exogenous albumin chronic administration will be

This study was designed to assess whether artificial ascites has a heat-sink effect on the ablation zone for percutaneous radiofrequency ablation (RFA) of hepatic tumors abutting the diaphragm. We retrospectively assessed 28 patients who underwent percutaneous RFA for the treatment of a single nodular hepatic tumor that abutted the diaphragm from July 2000 to December 2006. All patients underwent ultrasound-guided RFA using internally cooled electrodes. A single ablation for 12 minutes was applied using 3-cm active-tip electrodes. We divided patients into two groups on the basis of whether artificial ascites was introduced before RFA: Group A consisted of patients who received artificial ascites with a mean of 760 mL of a 5% dextrose in water solution (n = 15) and group B consisted of patients who did not receive artificial ascites (n = 13). The volume of the ablation zone was measured on CT images obtained immediately after the ablation procedure, and imaging findings were compared for both groups using the Student's t test. We also compared the local tumor progression rate between both groups using the chi-square test (mean follow-up, 37.4 months). There was no significant difference between the two patient groups with regard to age, sex, Child-Pugh class, or tumor location (p > 0.05). The tumors were significantly smaller in group A patients (mean +/- SD, 1.6 +/- 0.5 cm) than in group B patients (2.1 +/- 0.7 cm) (p = 0.019). The mean volume of the RFA zone was 31.6 +/- 11.9 cm(3) in group A patients and 30.9 +/- 11.0 cm(3) in group B patients. There was no significant difference between the groups in the ablation volume (p = 0.871). Local tumor progression was noted in four patients (26.7%) in group A and in three patients (23.1%) in group B. There was no significant difference in the local tumor progression rate between the two groups (p = 0.83). Artificial ascites did not show a heat-sink effect on the volume of the ablation zone after percutaneous RFA for the

Malignant pleural effusion (PE) and ascites, common clinical manifestations in advanced cancer patients, are associated with a poor prognosis. However, the biological characteristics of malignant PE and ascites are not clarified. Here we report that malignant PE and ascites can induce a frequent epithelial-mesenchymal transition program and endow tumor cells with stem cell properties with high efficiency, which promotes tumor growth, chemoresistance, and immune evasion. We determine that this epithelial-mesenchymal transition process is mainly dependent on VEGF, one initiator of the PI3K/Akt/mechanistic target of rapamycin (mTOR) pathway. From the clinical observation, we define a therapeutic option with VEGF antibody for malignant PE and ascites. Taken together, our findings clarify a novel biological characteristic of malignant PE and ascites in cancer progression and provide a promising and available strategy for cancer patients with recurrent/refractory malignant PE and ascites.

Effects of dietary L-carnitine and coenzyme Q10 (CoQ10) at different supplemental ages on performance and some immune response were investigated in ascites-susceptible broilers. A 3 x 2 x 2 factorial design was used consisting of L-carnitine supplementation (0, 75, and 100 mg/kg), CoQ10 supplementation (0 and 40 mg/kg) and different supplemental ages (from day 1 on and from day 10 on). A total of 480 one-day-old Arbor Acre male broiler chicks were randomly allocated to 12 groups, every group had five replicates, each with eight birds. The birds were fed a corn-soybean based diet for six weeks. From day 10-21, all the birds were exposed to a low ambient temperature (12-15 degrees C) to increase the susceptibility to ascites. No significant effects were observed on growth performance by L-carnitine, CoQ10 supplementation, and different supplemental ages. Packed cell volume was significantly decreased by L-carnitine supplementation alone, and ascites heart index and ascites mortality were decreased by L-carnitine, CoQ10 supplementation alone, and L-carnitine + CoQ10 supplementation together (p < 0.05). Heart index of broilers was significantly improved by L-carnitine, CoQ10 supplementation alone during 0-3 week. Serum IgG content was improved by L-carnitine supplementation alone (p < 0.05), but lysozyme activity was increased by L-carnitine + CoQ10 supplementation together (p < 0.05). A significant L-carnitine by supplemental age interaction was observed in lysozyme activity. L-carnitine supplementation alone had no effects on the peripheral blood lymphocyte (PBL) proliferation in response to concanavalin A (ConA) and lipopolysaccharide, but supplemental CoQ10 alone and L-carnitine+ CoQ10 together decreased the PBL proliferation in response to ConA (p < 0.05). The present study suggested that L-carnitine + CoQ10 supplementation together had positive effects on some immune response of ascites-susceptible broilers, which might benefit for the reduction of broilers

Sepsis-induced inflammation in the gut/peritoneal compartment occurs early in sepsis and can lead to acute lung injury (ALI). We have suggested that inflammatory ascites drives the pathogenesis of ALI and that removal of ascites with an abdominal wound vacuum prevents ALI. We hypothesized that the time- and compartment-dependent changes in inflammation that determine this process can be discerned using principal component analysis (PCA) and Dynamic Bayesian Network (DBN) inference. To test this hypothesis, data from a previous study were analyzed using PCA and DBN. In that study, two groups of anesthetized, ventilated pigs were subjected to experimental sepsis via intestinal ischemia/reperfusion and placement of a peritoneal fecal clot. The control group (n = 6) had the abdomen opened at 12 h after injury (T12) with attachment of a passive drain. The peritoneal suction treatment (PST) group (n = 6) was treated in an identical fashion except that a vacuum was applied to the peritoneal cavity at T12 to remove ascites and maintained until T48. Multiple inflammatory mediators were measured in ascites and plasma and related to lung function (PaO2/FIO2 ratio and oxygen index) using PCA and DBN. Peritoneal suction treatment prevented ALI based on lung histopathology, whereas control animals developed ALI. Principal component analysis revealed that local to the insult (i.e., ascites), primary proinflammatory cytokines play a decreased role in the overall response in the treatment group as compared with control. In both groups, multiple, nested positive feedback loops were inferred from DBN, which included interrelated roles for bacterial endotoxin, interleukin 6, transforming growth factor β1, C-reactive protein, PaO2/FIO2 ratio, and oxygen index. von Willebrand factor was an output in control, but not PST, ascites. These combined in vivo and in silico studies suggest that in this clinically realistic paradigm of sepsis, endotoxin drives the inflammatory response in the

Ovarian cancer cells were isolated from ascites fluid of 30 different patients diagnosed with cystadenocarcinoma of ovaries. Large colonies of malignant ASC cells were observed during the first week of cell growth in vitro. Colony formation was followed by fusion of cells and formation of large multinucleated and highly vacuolated syncytia. In contrast, cells isolated from the ascites fluid produced by patients with benign mucinous cystadenoma of ovaries did not form syncytia. Nonmalignant Brenner tumor cells, isolated from the ascites fluid, also did not form syncytia. Syncytia, but not the nonmalignant tumor cells, were immunofluorescence stained with an anti-human immunodeficiency virus type 1 (HIV-1) gp120 monoclonal antibody (MAb) and MAb RAK-BrI. Both MAbs recognized cancer-associated antigens RAK (for Rakowicz markers) p120, p42, and p25. Exposure of ASC cells to either the anti-HIV-1 gp120 MAb or MAb RAK-BrI inhibited syncytium formation. PCR with HIV-1 Env-derived primers revealed DNA sequences with over 90% homology to HIV-1 gp41 in syncytia and in ovarian cancer cells but not in normal ovary cells. Electron microscopic analysis revealed viral particles, hexagonal in shape (90 nm in diameter), with a dense central core surrounded by an inner translucent capsid and dense outer shell with projections. Negative staining detected membrane-covered particles (100 to 110 nm in diameter) in the cell culture medium. Incubation of normal breast cells with viral particles resulted in drastic morphological changes and syncytium formation by the transformed breast cells. The cytopathic effects of the identified virus resembled those of spumaviruses, which, in addition to their epitopic and genetic homology to HIV-1, might suggest a common phylogeny. PMID:9874674

Objectives Epithelial ovarian cancer (EOC) typically presents with advanced disease. Even with optimal debulking and response to adjuvant chemotherapy, the majority of patients will have disease relapse. We evaluated cytokine and chemokine profiles in ascites at primary surgery as biomarkers for progression-free survival (PFS) and overall survival (OS) in patients with advanced EOC. Methods Retrospective analysis of patients (n =70) who underwent surgery at Roswell Park Cancer Institute between 2002-12, followed by platinum-based chemotherapy. Results The mean age at diagnosis was 61.8 years, 85.3% had serous EOC, and 95.7% had stage IIIB, IIIC, or IV disease. Univariate analysis showed that ascites levels of tumor necrosis factor (TNF)-α were associated with reduced PFS after primary surgery. Although the ascites concentration of interleukin (IL)-6 was not by itself predictive of PFS, we found that stratifying patients by high TNF-α and high IL-6 levels identified a sub-group of patients at high risk for rapid disease relapse. This effect was largely independent of clinical prognostic variables. Conclusions The combination of high TNF-α and high IL-6 ascites levels at primary surgery predicts worse PFS in patients with advanced EOC. These results suggest an interaction between ascites TNF-α and IL-6 in driving tumor progression and resistance to chemotherapy in advanced EOC, and raise the potential for pre-treatment ascites levels of these cytokines as prognostic biomarkers. This study involved a small sample of patients and was an exploratory analysis; therefore, findings require validation in a larger independent cohort. PMID:26001328

To compare point-of-care ultrasound and physical examination (PEx), each performed by first-year medical students after brief teaching, for assessing ascites and hepatomegaly. Ultrasound and PEx were compared on: (1) reliability, validity and performance, (2) diagnostic confidence, ease of use, utility, and applicability. A single-center, randomized controlled trial was performed at a tertiary centre. First-year medical students were randomized to use ultrasound or PEx to assess for ascites and hepatomegaly. Cohen's kappa and interclass coefficient (ICC) were used to measure interrater reliability between trainee assessments and the reference standard (a same day ultrasound by a radiologist). Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were compared. A ten-point Likert scale was used to assess trainee diagnostic confidence and perceptions of utility. There were no significant differences in interobserver reliability, sensitivity, specificity, accuracy, PPV, or NPV between the ultrasound and PEx groups. However, students in the ultrasound group provided higher scores for perceived utility (ascites 8.38 ± 1.35 vs 7.08 ± 1.86, p  = 0.008; hepatomegaly 7.68 ± 1.52 vs 5.36 ± 2.48, p  < 0.001) and likelihood of adoption (ascites 8.67 ± 1.61 vs 7.46 ± 1.79, p  = 0.02; hepatomegaly 8.12 ± 1.90 vs 5.92 ± 2.32, p  = 0.001). When performed by first-year medical students, the validity and reliability of ultrasound is comparable to PEx, but with greater perceived utility and likelihood of adoption. With similarly brief instruction, point-of-care ultrasonography can be as effectively learned and performed as PEx, with a high degree of interest from trainees.

The effect of feed restriction and the application of canola oil to broiler straw litter to contain respirable dust on growth performance, carcass traits, and the incidence of ascites was evaluated with 800 male broilers studied in two 6-wk periods. Two pens of birds were feed restricted. Two pens of birds received feed ad libitum for the 6-wk trial. One restricted and one ad libitum pen received biweekly addition of canola oil to the litter. At 6 wk of age, 30 birds from each pen were killed for determination of breast muscle, fat pad, and heart weights. All birds were scored for the incidence of ascites at processing. A cross sectional image of each heart was digitally recorded and, using image analysis, the right ventricular area (RVA), left ventricular area (LVA), and total heart area (HA) were determined. The right ventricular wall was removed and its weight was expressed as a percentage of total heart weight (PRVW). The 40-d BW was significantly greater in the ad libitum birds (2.07 kg) than in the feed-restricted birds (1.86 kg). The right ventricular weight (RVW) (1.69 and 1.92 g) and the RVA (0.35 and 0.40 cm2) were also significantly different between the two feeding treatments. The ascites score was significantly correlated to the RVW (r = 0.50) and RVA (r = 0.52). The RVA was also correlated to the RVW (r = 0.63). Oiling the litter did not result in differences in carcass characteristics. Litter oiling significantly reduced the RVA of the ad libitum birds (0.36 cm2) compared to the ad libitum birds that did not have oiled litter (0.44 cm2). Feed restriction reduced the incidence of ascites, but also reduced gain. Litter oiling in the feed-restricted groups reduced the RVA, but did not reduce mortality.

Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoid malignancy and the most common type of non-Hodgkin's lymphomas, the stomach is the most common extranodal site. Gastric DLBCL is often characterized by epigastric pain and vomiting. We report a case of a 78-year-old female patient with gastric diffuse large B-cell lymphoma (DLBCL) with high CD8 level which was initially manifested with ascites of unknown origin. The patient was admitted with a chief complaint of abdominal distension and scanty urine over the last twenty days, while without anorexia and fatigue until 15 March. She had no history of viral hepatitis, tuberculosis, schistosomiasis. Laboratory data revealed normal aminotransferases and bilirubin levels, but serum lactate dehydrogenase, CA125, ascitic fluid lactate dehydrogenase, ascitic fluid lymphocytes increased. The ascitic fluid was yellow-colored with 98.5% lymphocytes. Stool occult blood test was positive. Upper gastrointestinal endoscopy performed a few days later revealed multiple gastric crateriform ulcers, and Helicobacter pylori was detected in the biopsy specimen. Peripheral blood CD8+ was increased by 51%. Pathology test showed lymphocytes with atypical hyperplasia, and immunohistochemistry test resulted CD20+, CD10-, CD79α+, κ+, bcl-6+, Ki-67+ (approximately 95%), λ-, bcl-2-, CD3-, CD43-. Immunoglobulin gene (Ig) clonal rearrangement showed IgH: FR1 (+), FR2 (+), FR3(-), Igk: VJ(+), Vkde (+) in lymphoma tissue. The features of histopathology and immunohistochemistry of the tissue confirmed diffuse large B-cell lymphoma (DLBL). The patient received an uncompleted CHOP program combined with H. pylori eradication. However, the patient deceased due to disease development sixteen days later after the diagnosis.

Daily exposure of mouse recipients of Ehrlich ascites carcinoma to electromagnetic radiation of the microwave range leads to a change in the dynamics of tumor growth by decreasing the total number of cells. The number of tumor cells with blebbing morphological signs after microwave radiation increases gradually with tumor growth. The maximum content of tumor cells in the state of blebbing is observed during active proliferation in tumor-recipient mice of the control group (without irradiation).

Ethanol-insoluble components were extracted from fresh garlic with 0.9% NaCl solution containing streptomycin and penicillin. This extract, containing approximately 10% sugar, 0.3% nitrogen, and 0.4% ash, was termed garlic sugar solution. This garlic sugar solution (Medium 1) was used as the suspending medium for Ehrlich ascites tumor cells attenuated with allicin, the main principle of garlic, and 0.9% NaCl solution containing streptomycin and penicillin (Medium 2) was also used as the suspending medium. Mice of DDD strain were immunized with the attenuated tumor cells suspended in Medium 1 or 2. After immunization, the immunized and control mice were challenged intraperitoneally with viable Ehrlich ascites tumorcells. Animals immunized with the attenuated tumor cells suspended in Medium 1 acquired significantly stronger resistance against the tumor cells than animals immunized with those suspended in Medium 2.

Immunotherapy of BALB/c mice bearing Ehrlich ascites tumor with vitamin D-binding protein-derived macrophage activating factor.

PubMed

Yamamoto, N; Naraparaju, V R

1997-06-01

Vitamin D3-binding protein (DBP; human DBP is known as Gc protein) is the precursor of macrophage activating factor (MAF). Treatment of mouse DBP with immobilized beta-galactosidase or treatment of human Gc protein with immobilized beta-galactosidase and sialidase generated a remarkably potent MAF, termed DBPMAF or GcMAF, respectively. The domain of Gc protein responsible for macrophage activation was cloned and enzymatically converted to the cloned MAF, designated CdMAF. In Ehrlich ascites tumor-bearing mice, tumor-specific serum alpha-N-acetylgalactosaminidase (NaGalase) activity increased linearly with time as the transplanted tumor cells grew in the peritoneal cavity. Therapeutic effects of DBPMAF, GcMAF, and CdMAF on mice bearing Ehrlich ascites tumor were assessed by survival time, the total tumor cell count in the peritoneal cavity, and serum NaGalase activity. Mice that received a single administration of DBPMAF or GcMAF (100 pg/mouse) on the same day after transplantation of tumor (1 x 10(5) cells) showed a mean survival time of 35 +/- 4 days, whereas tumor-bearing controls had a mean survival time of 16 +/- 2 days. When mice received the second DBPMAF or GcMAF administration at day 4, they survived more than 50 days. Mice that received two DBPMAF administrations, at days 4 and 8 after transplantation of 1 x 10(5) tumor cells, survived up to 32 +/- 4 days. At day 4 posttransplantation, the total tumor cell count in the peritoneal cavity was approximately 5 x 10(5) cells. Mice that received two DBPMAF administrations, at days 0 and 4 after transplantation of 5 x 10(5) tumor cells, also survived up to 32 +/- 4 days, while control mice that received the 5 x 10(5) ascites tumor cells only survived for 14 +/- 2 days. Four DBPMAF, GcMAF, or CdMAF administrations to mice transplanted with 5 x 10(5) Ehrlich ascites tumor cells with 4-day intervals showed an extended survival of at least 90 days and an insignificantly low serum NaGalase level between days 30 and 90.

The study aimed to evaluate the effects of tolvaptan treatment on survival of patients with decompensated liver cirrhosis with refractory ascites. This multicenter, retrospective, observational study included patients with cirrhosis who were treated with tolvaptan for hepatic ascites refractory to conventional diuretics. Patients who could and could not decrease accompanying diuretics within 1 month after tolvaptan administration were defined as the "Decreased" and "Not-decreased" groups, respectively. Median body weight change 1 week after tolvaptan treatment was -1.95 kg, with the 50% of patients experiencing a 2 kg/week reduction. Spot urinary sodium was found to be a better predictor of tolvaptan response than liver function and liver fibrosis markers. Median survival was significantly longer (not reached versus 116 days, p = 0.005) and serum creatinine concentrations 12 weeks after tolvaptan administration significantly lower (0.99 vs. 1.55 mg/dL, p < 0.05) in the Decreased than in the Not-decreased group. Multivariate analysis showed that the presence of viable hepatocellular carcinoma (hazards ratio [HR] 2.14, p = 0.02) and a decrease in diuretics were independently prognostic of survival (HR 0.36, p < 0.01). The maintenance of renal function is essential in enhancing survival of patients with cirrhosis. Doses of diuretics should be adjusted appropriately during tolvaptan treatment. © 2018 S.

Although the herbal pair of Euphorbia kansui (GS) and Glycyrrhiza (GC) is one of the so-called "eighteen antagonistic medicaments" in Chinese medicinal literature, it is prescribed in a classic Traditional Chinese Medicine (TCM) formula Gansui-Banxia-Tang for cancerous ascites, suggesting that GS and GC may exhibit synergistic or antagonistic effects in different combination designs. Here, we modeled the effects of GS/GC combination with a target interaction network and clarified the associations between the network topologies involving the drug targets and the drug combination effects. Moreover, the "edge-betweenness" values, which is defined as the frequency with which edges are placed on the shortest paths between all pairs of modules in network, were calculated, and the ADRB1-PIK3CG interaction exhibited the greatest edge-betweenness value, suggesting its crucial role in connecting the other edges in the network. Because ADRB1 and PIK3CG were putative targets of GS and GC, respectively, and both had functional interactions with AVPR2 approved as known therapeutic target for ascites, we proposed that the ADRB1-PIK3CG-AVPR2 signal axis might be involved in the effects of the GS-GC combination on ascites. This proposal was further experimentally validated in a H22 hepatocellular carcinoma (HCC) ascites model. Collectively, this systems-level investigation integrated drug target prediction and network analysis to reveal the combination principles of the herbal pair of GS and GC. Experimental validation in an in vivo system provided convincing evidence that different combination designs of GS and GC might result in synergistic or antagonistic effects on HCC ascites that might be partially related to their regulation of the ADRB1-PIK3CG-AVPR2 signal axis.

To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. A total of 226 advanced schistosomiasis patients with ascites were randomly divided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing, while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed, and the quality of life of the patients before and after hospital discharge was assessed. The improvement rate, satisfaction degree, and awareness rate of health knowledge of the patients in the experiment group were 93.8%, 100% and 97.4%, respectively, which were significantly higher than those of the control group (all P < 0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%, respectively, which were significantly lower than those of the control group (both P < 0.05). In addition, the average hospitalization days and the hospitalization cost of the experiment group were (12.2 ± 0.7) d and (4 725.0 ± 310.1) Yuan respectively, which were less than those of the control group (both P < 0.01). When 6 months after the discharge from hospital, the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group (all P < 0.05). The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites; meanwhile, it can shorten the hospitalization time and save the hospitalization cost. Therefore, this nursing model is suitable for popularization and application in the treatment and nursing work of the advanced schistosomiasis assistance.

Nocardia veterana is a recently characterized species within the genus Nocardia, and only three human clinical isolates have been reported for this species. We describe a case of ascitic fluid infection in an immunocompromised patient due to N. veterana. To our knowledge, this is the first report of a Nocardia sp. strain from ascitic fluid and the fourth report of N. veterana isolated from human samples. Chemotaxonomic methods showed the strain to belong to the genus Nocardia, and identification to the species level was done by 16S ribosomal DNA gene sequencing. The antibiotic susceptibility profile of N. veterana is reported here for the second time. The strain was deposited in the Collection of the Pasteur Institute and in the Culture Collection of the University of Göteborg (CIP 107497 and CCUG 46576). The corresponding 16S ribosomal DNA gene sequence is available from the GenBank database under accession number AY149599. A phylogenetic analysis was conducted and showed that N. veterana was most closely related to the recently characterized species Nocardia africana rather than to Nocardia vaccinii, as previously reported.

Intensive selection of broilers for faster growth and better feed efficiency resulted in greater susceptibility to metabolic disorders such as ascites syndrome, which is one of the major causes of mortality and economic loss in broiler industry. Whereas cool temperature is one of the primary triggers for ascites, early feed restriction (FDR) significantly alleviates its incidence and mortality. However, little is known about effects of FDR, cold environmental temperature and their interaction on physiological responses in broiler chickens. For this purpose, 320 one-day-old male broilers were divided into two treatment groups of Ad libitum (Ad) and feed restricted (FR) with eight pen replicates each. Chickens in FR group underwent feed access limitation from days 7 to 14 of age. On day 21 half of the birds (four pens) in each group exposed to the cold temperature (CT) and the other half (four pens) continued at normal temperature (NT). Average daily feed intake, average daily weight gain and feed conversion ratio (FCR) were measured at days 7, 14, 21, 28 and 42. At 39 and 46 days of age two chicks with a BW around the pen average were selected from each pen and slaughtered after collecting blood samples. Then, relative weight of internal organs and right ventricle weight per total ventricle weight (RV : TV) ratio were calculated. Compared with NT group, CT birds had higher daily feed intake and FCR (P<0.05) from day 28 to 42. Cumulative ascites mortality in CT chickens was higher (P<0.001) than NT chicks. Within the CT group, ascites mortality in FR chickens was reduced (P<0.001) to 1.25% compared with 8.75% in Ad chicks. Birds in CT group had significantly (P<0.05) thicker right ventricle and greater relative weight of heart, hematocrit and triiodothyronine concentration. However, none of these parameters were affected by FDR. Under cold stress conditions, FDR reduced activity of alanine aminotransferase and aspartate aminotransferase (P<0.05). Serum triglyceride

Extracellular fluid volume (E.C.F.) and plasma volume (P.V.), were measured with sodium sulfate labeled with 35I and 131I human serum albumin, respectively, by the dilution technique in control subjects and in cirrhotic patients without clinical ascites or edema, renal or hepatic failure, gastrointestinal bleeding or diuretics. Results are expressed as mean +/- DS in both ml/m2 and ml/kg. In normal subjects E.C.F. (n = 8) was 7,533 +/- 817 ml/m2 (201.3 +/- 182 ml/kg), P.V. (n = 11) 1,767 +/- 337 ml/m2 (47.2 +/- 9.3 ml/kg), and interstitial fluid (I.S.F.) (n = 7) 5,758 +/- 851 ml/m2 (Table 2). In cirrhotic patients E.C.F. (n = 11) was 10,318 +/- 2,980 ml/m2 (261.7 +/- 76.8 ml/kg), P.V. (n = 12) 2,649 +/- 558 ml/m2 (67.7 +/- 15.6 ml/kg) and I.S.F. (n = 11) 7,866 +/- 2,987 ml/m2 (Table 3). Cirrhotic patients compared with normal subjects have hypervolemia due to a significant E.C.F. and P.V. expansion (p less than 0.02 and less than 0.001 respectively) (Fig. 1). Reasons for E.C.F. and P.V. abnormalities in cirrhotic patients may reflect urinary sodium retention related to portal hipertension which stimulates aldosterone release or enhanced renal tubular sensitivity to the hormone. However, it is also possible that these patients, in the presence of hypoalbuminemia (Table 1), have no clinical edema or ascites due to increased glomerular filtration, suppressed release of vasopressin, increased natriuretic factor, and urinary prostaglandin excretion, in response to the intravascular expansion, all of which increased solute and water delivery to the distal nephron and improved renal water excretion. We conclude that in our clinical experience cirrhotic patients without ascites or edema have hypervolemia because of a disturbance in E.C.F.

Membrane-associated actin from the microvillar membranes of ascites tumor cells

PubMed Central

1982-01-01

A membrane fraction (MF2) has been purified from isolated microvilli of the MAT-C1 subline of the 13762 rat mammary ascites adenocarcinoma under conditions which cause F-actin depolymerization. This membrane preparation contains actin as a major component, although no filamentous structures are observed by transmission electron microscopy. Membranes were extracted with a Triton X-100-containing actin-stabilizing buffer (S buffer) or actin-destabilizing buffer (D buffer). In D buffer greater than 90% of metabolically labeled protein and glycoprotein was extracted, and 80-90% of these labeled species was extracted in S buffer. When S buffer extracts of MF2 were fractionated by either gel filtration on Sepharose 6 B or rate-zonal sucrose density gradient centrifugation, most of the actin was found to be intermediate in size between G- and F-actin. In D buffer most of the MF2 actin behaved as G-actin. Extraction and gel filtration of intact microvilli in S buffer also showed the presence of the intermediate form of actin, indicating that it did not arise during membrane preparation. When [35S]methionine-labeled G-actin from ascites cells was added to S buffer extracts of MF2 and chromatographed, all of the radioactivity chromatographed as G-actin, indicating that the intermediate form of actin did not result from an association of G-actin molecules during extraction or chromatography. The results of this study suggest that the microvillar membrane fraction is enriched in an intermediate form of actin smaller than F-actin and larger than G-actin. PMID:6890066

To determine whether dogs with ascites secondary to right-sided congestive heart failure (CHF) have bleeding disorders associated with hypofibrinogenemia and discordant plasma fibrin-fibrinogen degradation products (FDPs) and D-dimer assay results (ie, a circulating concentration of FDPs higher than the reference range and a circulating concentration of D-dimer within the reference range). Retrospective case-control study. 80 client-owned dogs. Dogs with ascites secondary to right-sided CHF (group 1; n = 20), unhealthy dogs without cardiac disease (group 2; 40), and dogs with left-sided CHF (group 3; 20) were included in the study. Urine bile acids-to-creatinine concentration ratios were calculated as a marker of liver function. Differences among groups regarding coagulation profile analysis results and prevalence of discordant FDPs and D-dimer assay results were determined. No significant differences were detected among the 3 groups regarding urine bile acids-to-creatinine concentration ratios. Plasma fibrinogen concentration was significantly lower for group 1 versus groups 2 or 3. Prevalence of discordant FDPs and D-dimer assay results was significantly higher for group 1 versus groups 2 or 3. Eighteen group 1 dogs had discordant FDPs and D-dimer assay results. Ten of these dogs had concurrent hypofibrinogenemia, 2 of which had clinical signs of bleeding. Only 10 dogs in groups 2 or 3 had discordant FDPs and D-dimer assay results; none of these dogs had hypofibrinogenemia or clinical signs of bleeding. Dogs with right-sided CHF and ascites may be at increased risk for primary hyperfibrinogenolysis (ie, hypofibrinogenemia and discordant FDPs and D-dimer assay results).

Purpose: Monoclonal antibodies are potentially powerful tools used in biomedical research, diagnosis, and treatment of infectious diseases and cancers. The monoclonal antibody against Human IgA can be used as a diagnostic application to detect infectious diseases. The aim of this study was to improve an appropriate protocol for large-scale production of mAbs against IgA. Methods: For large-scale production of the monoclonal antibody, hybridoma cells that produce monoclonal antibodies against Human IgA were injected intraperitoneally into Balb/c mice that were previously primed with 0.5 ml Pristane. After ten days, ascitic fluid was harvested from the peritoneum of each mouse. The ELISA method was carried out for evaluation of the titration of produced mAbs. The ascitic fluid was investigated in terms of class and subclass by a mouse mAb isotyping kit. MAb was purified from the ascitic fluid by ion exchange chromatography. The purity of the monoclonal antibody was confirmed by SDS-PAGE, and the purified monoclonal antibody was conjugated with HRP. Results: Monoclonal antibodies with high specificity and sensitivity against Human IgA were prepared by hybridoma technology. The subclass of antibody was IgG1 and its light chain was the kappa type. Conclusion: This conjugated monoclonal antibody could have applications in designing ELISA kits in order to diagnose different infectious diseases such as toxoplasmosis and H. Pylori. PMID:25789225

Regulatory T lymphocytes evoke the immune tolerance by suppressing and inactivating cytotoxic T lymphocytes. The objective of this study was to compare the proportion of regulatory T lymphocytes, precisely defined as CD4(+)CD25(high+)Foxp3(+) T lymphocytes, in primary and recurrent ovarian carcinoma before and after ex vivo expansion of ascites with interleukin-2 (IL-2). Ascitic fluid samples were obtained from 26 patients with ovarian carcinoma. Lymphocytes were isolated from ascites and cell markers were analyzed by flow cytometry using anti-CD3/CD4/CD8/CD16/CD56/CD25 and anti-Foxp3 antibodies. Lymphocytes were incubated for 2 to 3 weeks and expanded ex vivo by IL-2 stimulation and their phenotypes were analyzed by flow cytometry. Following ex vivo expansion, ascitic fluid lymphocytes increased by a greater extent in the recurrent group than in the primary group. The proportion of ex vivo-expanded lymphocytes changed as follows; CD4(+) T lymphocytes increased, CD8(+) T lymphocytes decreased, and the proportion of CD3(-)CD16(+)56(+) NK cells was unchanged. The proportion of CD4(+)CD25(high+)Foxp3(+) regulatory T lymphocytes in CD4(+) T lymphocytes increased after ex vivo expansion in both groups, but to a greater degree in the recurrent group. This study showed that regulatory T lymphocytes, neither cytotoxic T lymphocytes nor NK cells, were extensively increased after ex vivo expansion, especially in recurrent ovarian carcinoma. These results may provide information that helps to guide the future development of adoptive immunotherapy against ovarian carcinoma.

An 11-yr-old female cheetah (Acinonyx jubatus) was diagnosed clinically with hepatic and renal disease and euthanatized after an extended illness. Postmortem examination revealed 8-10 L of milky white fluid in the abdominal cavity and markedly dilated lymphatic vessels within the intestinal mesentery. The abdominal fluid was a chylous effusion based on the cytologic predominance of lymphocytes and macrophages and comparison of cholesterol and triglyceride levels in the fluid and in serum. Gross and histopathologic lesions in the liver were consistent with a diagnosis of venoocclusive liver disease. Chylous ascites is uncommon with human chronic liver disease and is rarely identified in animals.

Midodrine is an α-agonist prodrug of desglymidodrine used for the management of hypotension. Midodrine has demonstrated usefulness in hepatorenal syndrome. The objective of the present work was to study the role of midodrine in patients with non-azotemic cirrhosis with tense ascites. This prospective randomized double blind placebo-controlled study was conducted on 67 non azotemic inpatients with liver cirrhosis and tense ascites (52 men and 15 women; age range, 45-72). One patient declined to participate in the study, 33 patients were randomly assigned to take midodrine hydrochloride, and 33 patients were randomly assigned to take placebo. Out of 67 enrolled patients, 60 patients (30: in midodrine group; 30: in placebo group) completed the study and 6 patients lost to follow up. Patients were assessed for patients’ characteristics, history of tapping their ascetic fluid, laboratory values, and Doppler parameters before and after the study. Average 24-h urine volume was assessed before and after the start of the study. significant reduction in body weight and abdominal girth was observed after 2 weeks of midodrine therapy. Midodrine appeared to be effective in lowering body weights and abdominal girths of non azotemic cirrhotic patients with tense ascites.

Background & aims Prognostic tests are critical in the management of patients with cirrhosis and ascites. Biological tests or scores perform poorly in that situation. Mid-infrared fibre evanescent wave spectroscopy (MIR-FEWS) which allows for global serum metabolic profiling may provide more relevant information by measuring a wider range of metabolic parameters in serum. Here we present the accuracy of a MIR-FEWS based predictive model for the prognosis of 6 months survival in patients with ascites and cirrhosis. Methods Patients with ascites were prospectively included and followed up for 6 months. MIR-FEWS spectra were measured in serum samples. The most informative spectral variables obtained by MIR-FEWS were selected by FADA algorithm and then used to build the MIR model. Accuracy of this model was assessed by ROC curves and 90%/10% Monte Carlo cross-validation. MIR model accuracy for 6 months survival was compared to that of the Child-Pugh and MELD scores. Results 119 patients were included. The mean age was 57.36±13.70, the MELD score was 16.32±6.26, and the Child-Pugh score was 9.5±1.83. During follow-up, 23 patients died (20%). The MIR model had an AUROC for 6 months mortality of 0.90 (CI95: 0.88–0.91), the MELD 0.77 (CI95: 0.66–0.89) and Child-Pugh 0.76 (CI95: 0.66–0.88). MELD and Child-Pugh AUROCs were significantly lower than that of the MIR model (p = 0.02 and p = 0.02 respectively). Multivariate logistic regression analysis showed that MELD (p<0.05, OR:0.86;CI95:0.76–0.97), Beta blockers (p = 0.036;OR:0.20;CI95:0.04–0.90), and the MIR model (p<0.001; OR:0.50; CI95:0.37–0.66), were significantly associated with 6 months mortality. Conclusions In this pilot study MIR-FEWS more accurately assess the 6-month prognosis of patients with ascites and cirrhosis than the MELD or Child-Pugh scores. These promising results, if confirmed by a larger study, suggest that mid infrared spectroscopy could be helpful in the management of these patients

An accurate diagnosis of cancer of Müllerian origin is required before the initiation of treatment. An overlap in clinical presentation and cytological, histological, or imaging studies with other nongynecological tumors does occur. Therefore, immunocytochemistry markers are used to determine tumor origin. Human epididymis protein 4 (HE4) is overexpressed in tissue of epithelial ovarian cancer (EOC). It has shown to be a sensitive and specific serum marker for EOC and to be of value for the differentiation between EOC and ovarian metastases of gastrointestinal origin. The objective of the current study was to evaluate HE4 immunocytochemistry in malignant ascites for differentiation between cancer of Müllerian origin, including EOC, and adenocarcinomas of the gastrointestinal tract. Cytological specimens of 115 different adenocarcinomas (45 EOCs, 46 cases of gastric cancer, and 24 cases of colorectal cancer) were stained for HE4, paired box 8 (PAX8), and other specific markers. 91% of the ascites samples from patients with EOC stained for both HE4 and PAX8. The 4 samples without HE4 staining were a clear cell carcinoma, a low-grade serous adenocarcinoma, an undifferentiated adenocarcinoma, and a neuroendocrine carcinoma. All high-grade serous adenocarcinomas (n = 37, 100%) stained with HE4, compared with 94% that stained positively for PAX8. In cases of gastric or colorectal cancer, 25% and 21% of cases, respectively, stained positive for HE4. No PAX8 staining was observed in colorectal or gastric adenocarcinomas. HE4 staining in ascites is feasible and appears to have a high sensitivity for high-grade serous ovarian cancer. HE4 is a useful addition to the current panel of immunocytochemistry markers for the diagnosis of EOC and for differentiation with gastrointestinal adenocarcinomas.

Angiopoietin-like 4 (ANGPTL4) regulates plasma triglyceride levels by inhibiting LPL. Inactivation of ANGPTL4 decreases plasma triglycerides and reduces the risk of coronary artery disease. Unfortunately, targeting ANGPTL4 for the therapeutic management of dyslipidemia and atherosclerosis is hampered by the observation that mice and monkeys in which ANGPTL4 is inactivated exhibit lipid accumulation in the mesenteric lymph nodes (MLNs). In mice these pathological events exclusively unfold upon feeding a high saturated FA diet and are followed by an ultimately lethal pro-inflammatory response and chylous ascites. Here, we show that Angptl4−/− mice fed a diet rich in trans FAs develop numerous lipid-filled giant cells in their MLNs, yet do not have elevated serum amyloid and haptoglobin, do not exhibit ascites, and survive, unlike Angptl4−/− mice fed a saturated FA-rich diet. In RAW264.7 macrophages, the saturated FA, palmitate, markedly increased markers of inflammation and the unfolded protein response, whereas the trans-unsaturated elaidate and the cis-unsaturated oleate had the opposite effect. In conclusion, trans and saturated FAs have very distinct biological effects in macrophages. Furthermore, lipid accumulation in MLNs is uncoupled from activation of an acute-phase response and chylous ascites, suggesting that ANGPTL4 should not be fully dismissed as target for dyslipidemia.

The study objective was to determine the reliability and validity of the Chinese version of the Functional Assessment of Chronic Illness Therapy - Ascites Index (FACIT-AI). A forward-backward translation procedure was adopted to develop the Chinese version of the FACIT-AI, which was tested in 69 patients with malignant ascites. Cronbach's α, split-half reliability, and test-retest reliability were used to assess the reliability of the scale. The content validity index was used to assess the content validity, while factor analysis was used for construct validity and correlation analysis was used for criterion validity. The Cronbach's α was 0.772 for the total scale, and the split-half reliability was 0.693. The test-retest correlation was 0.972. The content validity index for the scale was 0.8-1.0. Four factors were extracted by factor analysis, and these contributed 63.51% of the total variance. Item-total correlations ranged from 0.591 to 0.897, and these were correlated with visual analog scale scores (correlation coefficient, 0.889; P<0.01). The Chinese version of the FACIT-AI has good reliability and validity and can be used as a tool to measure quality of life in Chinese patients with malignant ascites.

Xpert™ MTB/Rif is a multiplex hemi-nested real-time PCR-based assay to detect presence of M. tuberculosis within 2 hours of sample collection. The present study aimed at assessing efficacy of Xpert™ MTB/Rif assay for diagnosing peritoneal tuberculosis. Patients with exudative ascites, fluid negative for acid-fast bacilli on auramine O fluorescence staining and unyielding fluid cytology for malignant cells, were included. Ultrasound-guided omental biopsy samples were obtained in all. Xpert™ MTB/Rif assay on tissue samples was assessed against a composite "reference" standard for diagnosis of peritoneal tuberculosis, defined as presence of any of the three-culture showing M tuberculosis, granulomatous inflammation on histology or resolution of ascites with 2 months of antitubercular therapy. During January 2012-July 2013, 28 patients (age:43 ± 15 years; mean ± SD; male:20) were recruited. Serum ascitic albumin gradient was <1.1 in all except in four patients with underlying cirrhosis. Twenty-one of the 28 patients had peritoneal TB as diagnosed by composite reference standard (histology:18; culture:4; treatment response:3). Seven patients (25%) had an alternative diagnosis (metastatic carcinoma 2, adenocarcinoma 2, mesothelioma 2, and systemic lupus erythematous 1). Xpert™ MTB/Rif assay was positive in 4/21 patients with peritoneal tuberculosis and in none of the 7 patients with alternative diagnosis. Thus, sensitivity, specificity, positive, and negative predictive values for tissue Xpert™ MTB/Rif assay in diagnosing peritoneal tuberculosis were 19% (95% C.I: 6% to 42%), 100% (95% C.I: 59% to 100%), 100% (40% to 100%), and 29% (95% C.I: 13% to 51%), respectively. Tissue Xpert™ MTB/Rif assay was of limited use in diagnosing peritoneal tuberculosis.

The occurrence of refractory ascites in nearly 17% of patients with decompensated cirrhosis is an unresolved issue. Advanced liver disease, functional renal impairment, and vascular insensitivity to vasopressors are the main causes of its refractoriness. Therefore, the aim of this study was to evaluate the impact on diuresis, weight loss, and short-term survival if midodrine and rifaximin were added to the diuretic therapy (DT). The study evaluated the eligibility of 650 patients with cirrhosis and refractory ascites who were selected during the period from November 2011 to May 2015. A total of 50 patients were excluded and finally 600 were selected and divided into the following groups: patients exposed to DT (n=200) as a control group, or DT with midodrine and rifaximin group (n=400). Body weight, mean arterial pressure, and glomerular filtration rate were determined. Plasma renin and aldosterone were also determined. Follow-up was performed after 2, 6, and 12 weeks, and then every 2 months for 24 months. The mean arterial pressure was significantly higher in the midodrine and rifaximin group (P=0.000), and there was a highly significant weight loss after 12 weeks (12.5 kg) (P=0.000), a highly significant increase in serum sodium, urine output, and urinary sodium excretion (P=0.000), and creatinine clearance was more reduced in the control group. With rifaximin and midodrine, a complete response occurred in 310 (78%) patients, a partial response in 72 (18%), and no response in 18 (4%) versus 30 (15%), 110 (55%), and 60 (30%) in the control group, respectively (P=0.000). Midodrine and rifaximin significantly reduced paracentesis needs when compared with the controls (18 study patients vs. 75 DT-only patients, P=0.000). Adding rifaximin and midodrine to DT enhanced diuresis in refractory ascites with improved systemic, renal hemodynamics and short-term survival.

Ovarian cancer is highly dependent on tumor microvessels and angiogenesis regulated by vascular endothelial growth factors (VEGFs) and their receptors (VEGFRs) and angiopoietins (Ang) and their Tie receptors. We studied the efficacy of adenoviral (Ad) gene therapy with soluble VEGFR2 and Tie2 combined with paclitaxel and carboplatin for the treatment of ovarian cancer. An intraperitoneal human ovarian cancer xenograft model in nude mice (n = 44) was used in this study. Gene therapy was given intravenously when the presence of sizable tumors was confirmed in magnetic resonance imaging. The study groups were as follows: AdCMV as a control (group I), AdCMV with chemotherapy (group II), AdsVEGFR2 and AdsTie2 (group III), and AdsVEGFR2 and AdsTie2 with chemotherapy (group IV). Antitumor effectiveness was assessed by overall tumor growth, ascites, immunohistochemistry, microvessel density, and sequential magnetic resonance imaging analyses. AdsVEGFR2 and AdsTie2 gene therapy (group III) significantly reduced tumor weights as compared with group II (P = 0.007). Accumulation of ascites was significantly reduced when the mice were treated with AdsVEGFR2 and AdsTie2 gene therapy or with combined gene therapy and chemotherapy as compared with controls (P = 0.029 and P = 0.010, respectively). Vascular endothelial growth factor and Ang2 levels in ascites fluid were elevated after the gene therapy. Combined inhibition of VEGF/VEGFR2 and Ang/Tie2 pathways provided efficient therapy for ovarian cancer in mice. In addition, antiangiogenic gene therapy has potential as a treatment for the accumulation of ascites.

Primary prevention of spontaneous bacterial peritonitis (SBP) is an important strategy to reduce morbidity and mortality in cirrhotic patients with ascites. Efficacy and safety of alternating rifaximin and norfloxacin as primary prophylaxis is questionable. Three hundred thirty-four cirrhotic patients with high SAAG (≥1.1) ascites, protein level in ascitic fluid less than 1.5 g/dL with advanced liver disease (Child-Pugh score >9 points with serum bilirubin level >3 mg/dL) or renal impairment (serum creatinine level >1.2 mg/dL, blood urea nitrogen level >25 mg/dL, or serum sodium level <130 mEq/L) were included in an open-label, randomized study aimed at comparing alternating use of norfloxacin and rifaximin vs. norfloxacin or rifaximin alone as primary prophylaxis for SBP. Both intention-to-treat and per-protocol efficacy analyses were done after 6 months of treatment by assessment of ascitic fluid neutrophil count. Safety analysis was done for all intention-to-treat populations. Alternating norfloxacin and rifaximin showed superior prophylaxis by intention-to-treat (74.7 vs. 56.4% vs. 68.3%, p < 0.048). Pairwise analysis showed that alternating regimen had lower probability to develop SBP when compared to a norfloxacin-based regimen in intention-to-treat (p = 0.016) and per protocol analysis (p = 0.039). There was no difference among the studied groups regarding the incidence and severity of adverse events reported. Alternating norfloxacin- and rifaximin-based primary prophylaxis for SBP showed higher efficacy with the same safety profile when compared with monotherapy of norfloxacin.

Experiments were carried out using various levels of sodium (Na+) from NaCl or NaHCO3 to determine: 1) the level of Na+ required to induce ascites alone or in combination with cold temperature and 2) the effect of Na+ on weight gain and fat deposition in broiler chickens. In experiment 1, there were no cases of ascites using levels of Na+, from NaCl at 0.14% to 0.44% in the feed from day 3 or using added Na+, from NaCl at 0.0% to 0.12% in the water from day 3 with a level of 0.14% in the feed. There was no significant difference in 21 or 42 day body weight, feed conversion, or right ventricle:total ventricle (RV:TV) ratio between treatment groups. Day 3 to 4 body weight gains were significantly increased in all treatment groups with added Na+ (p less than 0.01). In experiment 2, with levels of added Na+, from NaCl, at 0.0% to 0.12% in the water with a level of 0.20% in the feed there were two cases of ascites, one at day 7 and one at day 40 at the 0.12% level. There were no significant differences in body weight at days 21 or 42 or in the RV:TV ratios between groups. Feed conversions were improved (p less than 0.01) with the lowest and highest levels of Na+ and a significant increase in day 3 to 4 body weight gain, with increasing Na+ in all treatment groups, was observed.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1423057

Objective Hyponatremia is frequently observed in patients with decompensated liver cirrhosis and it is also related to a poor prognosis. The vasopressin V2-receptor antagonist tolvaptan is used to treat cirrhotic patients with ascites and increases the serum sodium (Na) level. In this study, we investigated (i) whether or not correction of the Na level improves the prognosis of cirrhotic patients with ascites and (ii) predictors of normalization of the serum Na level after tolvaptan therapy. Methods This was a single-center retrospective study. A total of 95 Japanese cirrhotic patients (60 men, median age 63 years) were enrolled and received tolvaptan orally after hospitalization for ascites treatment. The serum Na level was monitored during the period of tolvaptan treatment. The laboratory data and survival rates of patients who achieved serum Na levels of <135 and ≥135 mEq/L after 1 week were compared. Results Patients showed serum Na levels of 136 (121-145) mEq/L, and 42.1% had a serum Na level of <135 mEq/L. Among patients with an initial serum Na level <135 mEq/L, 60.0% achieved a normal level after 1 week, and the survival rate was significantly higher in patients with a normalized serum Na level (p<0.01). The pretreatment brain natriuretic peptide (BNP) level was predictive of achieving a serum Na level of ≥135 mEq/L (odds ratio: 0.87, 95% confidence interval: 0.316-0.987, p<0.05). Conclusion Normalization of the Na level after one week was associated with a favorable outcome of tolvaptan therapy, and Na correction improved the prognosis. PMID:28943585

In a 20-year-old primiparous patient, a routine ultrasound scan performed at 28 weeks revealed fetal ascites, bilateral talipes, and oligohydramnios. This woman, married to possibly her first cousin, was at risk for an autosomal recessive disease, a metabolic disorder. At 29 weeks, an amniotic fluid biochemical study revealed the presence of an abnormal band of free sialic acid, leading to a diagnosis of a congenital form of sialic acid storage disease. Termination of pregnancy was performed at 30 weeks. Measurement of free sialic acid in cultured fetal skin fibroblasts confirmed the diagnosis.

Amyloidosis is a systemic disease known to affect a vast range of organs, including the liver, heart, and kidney. When infiltrating the liver, amyloidosis typically does not present with cirrhosis. Typical presentation includes hepatomegaly with some mild laboratory abnormalities. A 72-year-old man presented with a 2-week history of worsening abdominal, scrotal, and extremity swelling. He endorsed melanotic stools and intermittent dizziness with a 10-pound weight gain. Vitals revealed a blood pressure of 82/57 mmHg and a pulse of 83 beats/min with positive orthostatic changes. Mild bibasilar crackles were noted. His abdomen was moderately distended with a fluid wave present, but no hepatosplenomegaly was noted. He displayed anasarca with significant extremity and scrotal edema, but no jaundice, telangiectasias, or other stigmata of chronic liver disease were present. Liver function tests demonstrated a total bilirubin of 1.5 mg/dL (normal value: 0.2-1.2 mg/dL), AST 111 IU/L (normal value 5-34 IU/L), ALT 51 IU/L (normal value 5-55 IU/L), and GGT 583 U/L (12-64 U/L). Alkaline phosphatase was 645 U/L (40-150 U/L). Analysis of peritoneal fluid was consistent with portal hypertension due to liver disease. Given an atypical presentation of cirrhosis with unclear etiology, a biopsy was performed and revealed amyloid deposition. Liver disease can be due to various etiologies, many of which can present ambiguously. Although the most typical etiologies have been well defined, we present a case of an atypical presentation of hepatic amyloidosis discovered in a patient with ascites and without typical hepatomegaly.

A study was made to determine the effectiveness of treating tumor-injected mice with verapamil, a calcium antagonist, and hyperthermia. The co-treatment reduced the incidence of tumors in animals injected with Meth A solid cells. It was shown that the decrease in tumors corresponded to increases in natural killer (NK) cell activity measured in a /sup 51/Cr release assay, in the amount of anti-Meth A antibody measured in an immunofluorescence assay, and a decrease in the amount of intra-tumor cyclic AMP measured by radioimmunoassay in co-treated compared to untreated sarcoma-injected animals. A role of the immune system for mediating the preventionmore » of sarcoma growth was indicated by Winn assays. Splenocytes sensitized in vivo against Meth A solid cells for 14 days exhibited an enhanced cytotoxic activity against syngeneic target cells compared to untreated tumor-sensitized splenocytes following heat-drug co-treatment. It was established that the stimulation of cytotoxic T cells against a histocompatibility antigen (H-2/sup d/) present on Meth A sarcoma cells resulted in tumor cell lysis. Animals bearing established Meth A solid sarcomas did not manifest tumor regressions following the administration of co-treatment alone or the adoptive transfer of co-treated tumor-sensitized splenocytes. The growth of Meth A ascites and Meth A ascites-derived solid sarcomas, unlike Meth A solid cell tumors, were not prevented in Winn assays. Additionally, the lifespan of animals injected with Meth A ascites cells was reduced by 50% compared to animals injected with Meth A solid sarcoma cells.« less

Patients with both cirrhosis and ascites have a 20% risk of developing umbilical hernia. A retrospective study from our center comparing conservative management of umbilical hernia with elective repair in these patients showed a significant risk of mortality as a result of hernia incarceration in conservatively treated patients. The goal of this study was to assess the safety and efficacy of elective umbilical hernia repair in these patients prospectively. Patients with liver cirrhosis and ascites presenting with an umbilical hernia were included in this study. For all patients, the expected time to liver transplantation was more than 3 months, and they did not have a patent umbilical vein in the hernia sac. The following data were collected prospectively for all patients: Child-Pugh-Turcotte (CPT) classification, model for end-stage liver disease (MELD) score, kidney failure, cardiovascular comorbidity, operation-related complications, and duration of hospital stay. Mortality rates were registered in hospital records and verified in government records during follow-up. Mortality rates were registered in hospital records and verified in government records during follow-up. On completion of the study, a retrospective survey was performed to search for any patients who met the study inclusion criteria but were left out of the study cohort. In total, 30 patients (25 males) underwent operation at a mean age of 58 years (standard deviation [SD] ± 9 years). Of these 30 patients, 6 were classified as CPT grade A (20%), 19 (63%) as grade B, and 5 (17%) as grade C. The patients' median MELD score was 12 (interquartile range [IQR], 8-16). In 10 (33%) of the 30 patients hernia repair was performed with mesh. The median duration of hospital stay was 3 days (IQR, 2-4). None of the patients were admitted to the intensive care unit. Postoperative complications included pneumonia and decompensation of cirrhosis (1 case each,) resulting in prolonged hospital stay for those 2

1. One hundred and sixty 1-d-old Arbor Acre male broiler chicks were fed with maize-soybean based diets for 6 weeks in a 2 x 2 factorial experiment. The factors were CoQ10 supplementation (0 or 40 mg/kg) and Escherichia coli lipopolysaccharide (LPS) challenge (LPS or saline). 2. CoQ10 was supplemented from d 1. From d 18, the chickens received three weekly i.p. injections of LPS (1.0 mg/kg BW) or an equivalent amount of sterile saline as control. From d 10 on, all chickens were exposed to low ambient temperature (12 to 15 degrees C) to induce ascites. 3. The blood packed cell volume and ascites heart index of broiler chickens were reduced by dietary CoQ10 supplementation. Mitochondrial State 3 and State 4 respiration, respiratory control ratio and phosphate oxygen ratio were not changed, but H+/site stoichiometry of complex II + III was elevated by dietary CoQ10 supplementation. 4. Cytochrome c oxidase and H+-ATPase activity were increased by CoQ10 supplementation, whereas NADH cytochrome c reductase and succinate cytochrome c reductase were not influenced. Mitochondrial anti-ROS capability was increased and malondialdehyde content was decreased by CoQ10 supplementation. 5. The work suggested that dietary CoQ10 supplementation could reduce broiler chickens' susceptibility to ascites, which might be the result of improving hepatic mitochondrial function, some respiratory chain-related enzymes activities and mitochondrial antioxidative capability.

1. The formation of adenosine 5′-phosphate, guanosine 5′-phosphate and inosine 5′-phosphate from [8-14C]adenine, [8-14C]guanine and [8-14C]hypoxanthine respectively in the presence of 5-phosphoribosyl pyrophosphate and an extract from Ehrlich ascites-tumour cells was assayed by a method involving liquid-scintillation counting of the radioactive nucleotides on diethylaminoethylcellulose paper. The results obtained with guanine were confirmed by a spectrophotometric assay which was also used to assay the conversion of 6-mercaptopurine and 5-phosphoribosyl pyrophosphate into 6-thioinosine 5′-phosphate in the presence of 6-mercaptopurine phosphoribosyltransferase from these cells. 2. At pH 7·8 and 25° the Michaelis constants for adenine, guanine and hypoxanthine were 0·9 μm, 2·9 μm and 11·0 μm in the assay with radioactive purines; the Michaelis constant for guanine in the spectrophotometric assay was 2·6 μm. At pH 7·9 the Michaelis constant for 6-mercaptopurine was 10·9 μm. 3. 25 μm-6-Mercaptopurine did not inhibit adenine phosphoribosyltransferase. 6-Mercaptopurine is a competitive inhibitor of guanine phosphoribosyltransferase (Ki 4·7 μm) and hypoxanthine phosphoribosyltransferase (Ki 8·3 μm). Hypoxanthine is a competitive inhibitor of guanine phosphoribosyltransferase (Ki 3·4 μm). 4. Differences in kinetic parameters and in the distribution of phosphoribosyltransferase activities after electrophoresis in starch gel indicate that different enzymes are involved in the conversion of adenine, guanine and hypoxanthine into their nucleotides. 5. From the low values of Ki for 6-mercaptopurine, and from published evidence that ascites-tumour cells require supplies of purines from the host tissues, it is likely that inhibition of hypoxanthine and guanine phosphoribosyltransferases by free 6-mercaptopurine is involved in the biological activity of this drug.

To evaluate the frequency of urinary peritonitis in children and to highlight its terms of management in a country with limited resources. We retrospectively observed nine case reports of urinary peritonitis collected in surgical reanimation service at the CHU of Antananarivo, from 1st January 2009 to 31 December 2012. Urinary peritonitis accounts 0.5% of all pediatric abdominal emergencies and 5% of pediatric urological emergencies collected in our service during study period. Three etiologies were traumatic bladder rupture, one bladder iatrogenic rupture, four secondary to obstructive uropathy and one other after cystolithotomy. We found a new case of posttraumatic transverse rupture of the bladder neck. Among obstructive uropathy observed, there were two cases of posterior urethral valves and two cases of ureteralpelvic junction obstruction. Clinical expression was dominated by fever, with abdominal distention and defense. In majority of cases, etiological diagnosis was made intraoperatively. The surgical treatment by laparotomy was performed under cover of systemic antibiotic therapy. Evolution was complicated with sepsis in three cases and acute renal failure in both cases. Surgical follow-up without complication were observed in four cases. A child has died to septic shock and multivisceral failure. Unlike urinary ascites resulting a transperitoneal extravasation of urine, uroperitoneum was a fistula between adominal cavity and content of the urinary tract. Urinary ascites was a rare cause of peritonitis. In contrast, uroperitoneum caused peritonitis quickly. Urinary peritonitis was a rare entity but severe prognosis in children. In majority of cases, etiological diagnosis was made intraoperatively. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

The effects of diurnal temperature fluctuations and removal of respirable dust, by application of canola oil to straw litter, on growth, carcass traits, and the degree of ascites was evaluated with 1,200 male broilers studied in two replicated 6-wk trials. Each trial used four pens of 150 birds. The temperature treatment consisted of a fluctuation of 3 C in temperature above the required temperature during the day (0600 to 1800 h) and 3 C below the required temperature at night (1800 to 0600 h) for a 6 C change in daily temperature. The control temperature was constant. All pens had the same mean daily temperature. In each trial, one control temperature pen and one fluctuation temperature pen received bi-weekly applications of canola oil to the litter (1.1 L/m2 of oil over 6 wk). At 6 wk of age, 30 birds from each pen were killed for determination of breast muscle, fatpad, and heart weights. All birds were scored for lesions of ascites at time of processing. A score of 0 or 1 represented slight pericardial effusion, slight pulmonary congestion, and edema. A score of 4 represented birds with marked accumulation of ascitic fluid in one or more ceolomic cavities (other than the pericardium) and advanced liver lesions. A cross-sectional image of each 4-mm heart slice (cross-section of the ventricles) was digitally recorded, and with image analysis we determined the right ventricular area (RVA), left ventricular area (LVA), and total heart area (HA). The final BW of the broilers were significantly different, the oiled-litter treatment (2,249 g) had lower weight gain compared with the nonoiled litter treatment (2,293 g). There were no differences in fatpad weight, shank length, lung weight, and percentage breast muscle between the main treatments. The Pectoralis minor and Pectoralis major weight were significantly heavier in the temperature fluctuation treatment than in the control temperature treatment by 3.0 and 12.0 g, respectively. The birds subjected to the control

kappa-Opioid receptor agonists (niravoline) or nonpeptide antidiuretic hormone (ADH) V2 receptor antagonists (OPC-31260) possess aquaretic activity in cirrhosis; however, there is no information concerning the effects induced by the chronic administration of these drugs under this condition. To compare the renal and hormonal effects induced by the long-term oral administration of niravoline, OPC-31260, or vehicle, urine volume, urinary osmolality, sodium excretion, and urinary excretion of aldosterone (ALD) and ADH were measured in basal conditions and for 10 days after the daily oral administration of niravoline, OPC-31260, or vehicle to cirrhotic rats with ascites and water retention. Creatinine clearance, serum osmolality, ADH mRNA expression, and systemic hemodynamics were also measured at the end of the study. Niravoline increased water excretion, peripheral resistance, serum osmolality, and sodium excretion and reduced creatinine clearance, ALD and ADH excretion, and mRNA expression of ADH. OPC-31260 also increased water metabolism and sodium excretion and reduced urinary ALD, although the aquaretic effect was only evident during the first 2 days, and no effects on serum osmolality, renal filtration, and systemic hemodynamics were observed. Therefore, both agents have aquaretic efficacy, but the beneficial therapeutic effects of the long-term oral administration of niravoline are more consistent than those of OPC-31260 in cirrhotic rats with ascites and water retention.

Total 30 patients (age 39.69 ± 21.26, 18M/12F) with clinical suspicion of tuberculosis peritonitis were included in this study after analyzing selection criteria. Laparoscopic peritoneal biopsy with 'histopathological diagnosis' was considered gold standard against which accuracics of two biomarkers (ADA & CA-125) were compared. Cut off value of ADA and CA-125 are 24 u/l, 35 U/ml respectively. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ADA as a diagnostic modality in tuberculos peritonitis were 87.5%, 83.33%, 95.45%, 62.5% and 86.67% respectively where as CA-125 was found to have 83.33% sensitivity, 50% specificity, 86.9% positive predictive value, 42.85% negative predictive value and 76.6% accuracy. Both biomarkers are simple, non-invasive, rapid and relatively cheap diagnostic test where as laparoscopy is an invasive procedure, costly & requires trained staff and not without risk and also not feasible in all the centre in our country. So ascitic fluid ADA and serum CA-125 are important diagnostic test for peritoneal tuberculosis.

To study antitumor activity of triptorelin - agonist of gonadotropin-releasing hormone and exemestane - inhibitor of aromatase in combination with cisplatin on the model of receptor-positive for estrogens and progesterone malignant transplantable ascites ovarian tumor (OT); to assess tumor response to treatment and VEGF expression in tumor cells under different combinations of cytostatic and hormonal drugs. 36 female Wistar rats, which underwent intraperitoneal transplantation of ascites OT (5×10(6) cells per animal), have been involved in the study. Rats were distributed into 4 groups (9 rats in each group): group 1 - animals, which received combination of cisplatin and triptorelin; group 2 - rats treated with combination of cisplatin and exemestane; group 3 - animals, which were administered with combination of cisplatin, triptorelin and exemestane; group 4 - rats, which received combination of triptorelin and exemestane. Histological study with assessment of treatment pathomorphosis in OT and immunohistochemical study have been carried out to analyze VEGF expression in OT cells. Survival of animals has been evaluated. Combination of cytostatic agent with triptorelin or exemestane has demonstrated significantly higher rates of treatment pathomorphosis (10.1 ± 0.1% and 16.2 ± 0.3%, respectively) and antiangiogenic activity in OT (21.4 ± 1.4% and 15.0 ± 1.3%, respectively), as well as the highest survival of animals (100.0 and 85.7%, respectively) as compared with the same in rats treated in regimen of monotherapy with cisplatin, triptorelin, exemestane or by combination of hormonal drugs. Among animals treated by combination of cytostatic drug with triptorelin, two were cured (22.2%), and among rats, which received cisplatin and exemestane, one animal (11.1%) was cured. Triptorelin and exemestane increase antitumor activity of cisplatin in respect to the transplantable malignant ascites OT and significantly increase survival of animals, especially when

To present prenatal diagnosis and array comparative genomic hybridization (aCGH) characterization of partial trisomy 16p (16p12.2→pter) and partial monosomy 22q (22q13.31→qter) presenting with fetal ascites and ventriculomegaly in the second trimester. A 31-year-old woman, gravida 2, para 1, was referred to the hospital at 20 weeks of gestation because of fetal ascites. Amniocentesis revealed a derivative chromosome 22. Subsequent parental karyotyping revealed that the father carried a balanced reciprocal translocation between 16p12 and 22q13. Bacterial artificial chromosome-based aCGH using amniocyte DNA demonstrated partial trisomy 16p and partial monosomy 22q [arr cgh 16p13.3p12.2 (CTD-3077J14→RP11-650D5)x3, 22q13.31q13.33 (RP1-111J24→CTD-3035C16)x1]. Oligonucleotide-based aCGH showed a 20.9-Mb duplication of distal 16p and an approximate 3.7-Mb deletion of distal 22q. Level II ultrasound revealed fetal ascites and ventriculomegaly. The pregnancy was terminated and a malformed male fetus was delivered with craniofacial dysmorphism and abnormalities of the digits. The fetal karyotype was 46,XY,der(22)t(16;22)(p12.2;q13.31)pat. The paternal karyotype was 46,XY,t(16;22)(p12.2;q13.31). Partial trisomy 16p can be associated with fetal ascites and ventriculomegaly in the second trimester. Prenatal sonographic detection of fetal ascites in association with ventriculomegaly should alert chromosomal abnormalities and prompt cytogenetic investigation, which may lead to the identification of an unexpected parental translocation involving chromosomal segments associated with cerebral and vascular abnormalities.

We tested the hypothesis that poultry by-product meal would produce a thermogenic response (an increased requirement for oxygen) resulting in an increased incidence of pulmonary hypertension with right ventricular failure and ascites in commercial broiler chickens. Four treatment groups, each with three replicates of 40 chicks, were fed a commercial broiler starter to day 21, grower to day 35, and the following experimental diets after day 35: group 1, commercial chicken broiler finisher; group 2, commercial chicken broiler finisher with poultry by-product meal added to replace part of the soyabean meal; group 3, commercial chicken broiler finisher with poultry fat added to replace the animal-vegetable (AV) fat; group 4, commercial chicken broiler finisher with both poultry by-product meal and poultry fat added to replace soyabean meal and AV fat. On day 35, pen temperature was reduced to 15°C, and on day 42 to 12°C. Mortality from ascites between days 35 and 56 was 11(9%) in group 2, 5(4%) in group 4 and 3(2.5%) in groups 1 and 3 The incidence of pulmonary hypertension, as measured by an increased right ventricle: total ventricle (RV:TV) ratio (RV:TV > 0.249) at processing on day 57, was higher in the groups receiving poultry by-product and poultry fat: 27(22.5%) in group 2, 26(21.7%) in group 3, and 20(16.7%) in group 4 compared to that of the controls 12(10%).

Hypoxia-inducible factor 1 (HIF-1) is a ubiquitously expressed heterodimeric transcription factor that mediates adaptive responses to hypoxia in all nucleated cells of metazoan organisms. Hypoxia-inducible factor 1α is involved in the pathogenesis of pulmonary hypertension in humans and animals, but whether HIF-1α is associated with the development of pulmonary hypertension syndrome (also known as ascites syndrome, AS) in broiler chickens has not been determined. In the present paper we addressed this issue by measuring the expression of HIF-1α mRNA in hearts and lungs of broiler chickens with AS induced by excess salt in drinking water. We conducted 2 experiments. The first experiment was used to observe the effects of excess salt on AS incidence. The results indicated that total incidence (20%) of AS in excess salt group (receiving 0.3% NaCl in drinking water) was much higher compared with the control group (receiving tap water) over a 43-d time course (P < 0.05). In the second experiment, we determined mean pulmonary arterial pressure (mPAP), ascites heart index (AHI), and expression of HIF-1α mRNA in lungs and hearts of broiler chickens after the excess salt treatment. Our results showed that excess salt induced pulmonary hypertension (indicated by higher mPAP) and right ventricular hypertrophy (greater ascites heart index) in broiler chickens. Meanwhile, the expression levels of HIF-1α mRNA in lungs and hearts were significantly increased at different time points in the excess salt group compared with the control group. Linear correlation analysis showed that the expression of HIF-1α mRNA in lungs was significantly positively correlated with mPAP (correlation coefficient = 0.79, P < 0.001), demonstrating that expression of HIF-1α mRNA was gradually increased in the excess salt group with the increase of pulmonary arterial pressure. In addition, the ascitic chickens showed significantly higher transcriptional levels of HIF-1α in hearts and lungs

Primary intestinal lymphangiectasia is a lymphatic system's disorder, where lymphatic drainage is blockaged. Clinically it produces malabsorption, protein-losing enteropathy, hypogammaglobulin in blood, and several degrees of malnutrition. Its treatment is not easy and includes dietetic-therapy and drugs. A 35-year-old-woman case report is exposed. She has recurrent chylosa ascites, requiring several admissions and evacuatory paracentesis. After food-fat was replaced by medium-chain triacyl-glicerol-enriched diet, a clinical, analytical and anthropometric improvement was demonstrated. The major way of treatment in intestinal lymphangiectasia in this case is the employement of specific-diet and adaptaded-basic-food. It's difficult and high collaboration of the patient is required, being necessary medical revisions during the whole life, due to the not well known evolution of this long-standing disease.

To investigate the efficacy and safety of 14 days' orally administered tolvaptan as adjunctive treatment for hepatic oedema in Japanese liver cirrhosis patients with insufficient response to conventional diuretics, with the option to increase dose in those who did not respond initially. This multicentre, single-arm, phase 3 study allocated patients with liver cirrhosis and persistent ascites to 7-day treatment with 7.5 mg/day tolvaptan followed by an additional 7 days' treatment. Responders at day 7 (achieving ≥ 1 kg body-weight reduction) continued on 7.5 mg/day tolvaptan; nonresponders (<1 kg body-weight reduction) received 15 mg/day tolvaptan. Conventional diuretic treatment continued throughout. The primary endpoint was change in body weight from baseline, as a marker of ascites volume. A total of 51 patients received 7.5 mg/day tolvaptan for 7 days, which caused a significant reduction in mean body weight (55% response rate). During the second 7-day treatment period, 30 patients received 7.5 mg/day tolvaptan and 13 patients received tolvaptan 15 mg/day: response rates were 43% and 23%, respectively. Two serious adverse events were observed. Serum sodium was within normal range. Tolvaptan therapy for 14 days (with possible dose increase as necessary), in combination with conventional diuretics, effectively reduced body weight in patients with hepatic oedema.

The intracellular synthesis and retention of polygammaglutamyl derivatives of methotrexate and their interactions with H/sub 2/ folate reductase was evaluated. Methotrexate polyglutamates were detected within 15 minutes in hepatocytes exposed to 1 microM methotrexate, and continued to accumulate for at least 60 minutes producing a large transmembrane gradient. These derivatives appeared to be preferentially retained within the cell. In studies with the Ehrlich ascites tumor accumulation of methotrexate polyglutamates was increased over 5-fold by the addition of 5 mM L-glutamine or L-glutamate and exhibited a positive correlation with the extracellular concentration of methotrexate. When Ehrlich ascites tumor cells were exposedmore » to 10 microM methotrexate and 5 mM L-glutamine intracellular polyglutamates were detected within 10 minutes and their levels increased linearly over 4 hours. As these derivatives accumulated, there was a decline in intracellular methotrexate due at least in part to a replacement of methotrexate on H/sub 2/ folate reductase by polyglutamates and subsequent efflux of the previously bound methotrexate from the cell. When polyglutamate derivatives were in excess of the H/sub 2/ folate reductase binding capacity and extracellular methotrexate removed, methotrexate rapidly exited the cell whereas the majority of its metabolites were retained and eventually saturated the major portion of the enzyme. These studies indicate that (1) intracellular methotrexate is rapidly converted to polygammaglutamyl derivatives, (2) these metabolites effectively compete with methotrexate for binding sites on H/sub 2/ folate reductase, (3) these derivatives are retained within the cell more effectively than methotrexate, and (4) vincristine and probenecid may be potentially useful for selectively increasing methotrexate polyglutamates in tumor cells.« less

Antitumor effect of vitamin D-binding protein-derived macrophage activating factor on Ehrlich ascites tumor-bearing mice.

PubMed

Koga, Y; Naraparaju, V R; Yamamoto, N

1999-01-01

Cancerous cells secrete alpha-N-acetylgalactosaminidase (NaGalase) into the blood stream, resulting in deglycosylation of serum vitamin D3-binding protein (known as Gc protein), which is a precursor for macrophage activating factor (MAF). Incubation of Gc protein with immobilized beta-galactosidase and sialidase generates the most potent macrophage activating factor (designated GcMAF). Administration of GcMAF to cancer-bearing hosts can bypass the inactivated MAF precursor and act directly on macrophages for efficient activation. Therapeutic effects of GcMAF on Ehrlich ascites tumor-bearing mice were assessed by survival time and serum NaGalase activity, because serum NaGalase activity was proportional to tumor burden. A single administration of GcMAF (100 pg/mouse) to eight mice on the same day after transplantation of the tumor (5 x 10(5) cells) showed a mean survival time of 21 +/- 3 days for seven mice, with one mouse surviving more than 60 days, whereas tumor-bearing controls had a mean survival time of 13 +/- 2 days. Six of the eight mice that received two GcMAF administrations, at Day 0 and Day 4 after transplantation, survived up to 31 +/- 4 days whereas, the remaining two mice survived for more than 60 days. Further, six of the eight mice that received three GcMAF administrations with 4-day intervals showed an extended survival of at least 60 days, and serum NaGalase levels were as low as those of control mice throughout the survival period. The cure with subthreshold GcMAF-treatments (administered once or twice) of tumor-bearing mice appeared to be a consequence of sustained macrophage activation by inflammation resulting from the macrophage-mediated tumoricidal process. Therefore, a protracted macrophage activation induced by a few administrations of minute amounts of GcMAF eradicated the murine ascites tumor.

Rifaximin is a non-absorbable antibiotic used to prevent relapses of hepatic encephalopathy which may also be a candidate for prophylaxis of spontaneous bacterial peritonitis (SBP). To detect the impact of rifaximin on the occurrence and characteristics of SBP. We prospectively studied all hospitalized patients that underwent a diagnostic paracentesis in our department from March 2012 to April 2013 for SBP and recorded all clinical data including type of SBP prophylaxis, prior use of rifaximin, concomitant complications of cirrhosis, as well as laboratory results and bacteriological findings. Patients were divided into the following three groups: no antibiotic prophylaxis, prophylaxis with rifaximin or with systemically absorbed antibiotic prophylaxis. Our study cohort comprised 152 patients with advanced liver cirrhosis, 32 of whom developed SBP during the study period. As expected, our study groups differed regarding a history of hepatic encephalopathy and SBP before inclusion into the study. None of the 17 patients on systemic antibiotic prophylaxis developed SBP while 8/27 patients on rifaximin and 24/108 without prophylaxis had SBP (p = 0.02 and p = 0.04 versus systemic antibiotics, respectively). In general, episodes of SBP were similar for patients treated with rifaximin and those without any prophylaxis. However, Escherichia coli and enterococci were dominant in the ascites of patients without any prophylaxis, while mostly klebsiella species were recovered from the ascites samples in the rifaximin group. Rifaximin pretreatment did not lead to a reduction of SBP occurrence in hospitalized patients with advanced liver disease. However, the bacterial species causing SBP were changed by rifaximin.

Cell-production rates estimated by the use of vincristine sulphate and flow cytometry. II. Correlation between the cell-production rates of ageing ascites tumours and the number of S phase tumour cells.

A new method for the evaluation of cell production rates combining flow cytometry (FCM) and the stathmokinetic method using vincristine sulphate (VS) has been used for the analysis of three aneuploid ascites tumours at different stages of growth. Using this technique it was possible to estimate the well-known decrease in cell production rates of ageing ascites tumours. The percentage of normal host cells in the aneuploid tumours studied was easily determined by FCM prior to the calculation of the tumour cell-production rates. A correlation was found between the percentage of tumour cells in the S phase and the tumour cell-production rate. This correlation is probably explained by the gradual transfer of proliferating cells in S phase to resting G1 and G2 phases with increasing tumour age.

In order to explain the biochemical mechanisms associated with deteriorating heart function in broiler chickens, this study compared myocardial high energy phosphate substrates in leghorns, feed restricted (Broilers-Res) broilers, ad libitum fed broilers (Broilers-AL), and in broilers that developed heart failure and ascites. The profile of adenine nucleotide content in the heart tissue did not differ between leghorns and Broilers-Res, but there were significant differences among Broilers-Res, Broilers-AL, and broilers with ascites. During intensive growth periods, leghorns and Broilers-Res showed increasing trends in heart ATP levels, whereas in fast growing broilers the heart ATP declined (p<0.021). ATP:ADP and ATP:CrP ratios increased with age in both leghorn and Broilers-Res, declined in fast growing broilers, and were the lowest in broilers that developed heart failure. The changes in heart high energy phosphate profile in broilers suggest that the energy demand of the heart during a rapid growth phase may exceed the bird's metabolic capacity to supply adequate levels of high energy phosphate substrate. The insufficiency of energy substrate likely contributes to the declining heart rate. In some individuals this may lead to impaired heart pump function, and in more severe cases may progress to heart pump failure.

Delivery of small interfering RNA (siRNA) is recently gaining tremendous attention for the treatment of ovarian cancer. The present study investigated the potential of different liposomal formulations composed of (2,3-dioleoyloxy-propyl)-trimethylammonium (DOTAP) and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE) encapsulating siRNA (hydration method) for their ability to knockdown luciferase (Luc) activity in human ovarian cancer SKOV-3 cells. Fluorescence single particle tracking (fSPT) and fluorescence correlation spectroscopy (FCS) in human-undiluted ascites fluid obtained from a peritoneal carcinomatosis patient revealed that cationic hydra-lipoplexes (HYDRA-LPXs) and HYDRA-LPXs decorated with stable DSPE-PEG (DSPE HYDRA-LPXs) showed high stability during at least 24 h. HYDRA-LPXs decorated with sheddable C8 and C16 PEG-Ceramides (Cer HYDRA-LPXs) resulted in rapid and premature release of siRNA already in the first hours. Despite their role in preventing aggregation in vivo, liposomes decorated with stable PEG residues resulted in a poor transfection compared to the ones decorated with sheddable PEG residues in reduced serum conditions. Yet, the transfection efficiency of both Cer HYDRA-LPXs significantly decreased following 1 h of incubation in ascites fluid due to a drastic drop in the cellular uptake, while DSPE HYDRA-LPXs are still taken up by cells, but too stable to induce efficient gene silencing.

Honey is thought to exhibit a broad spectrum of therapeutic properties including antibacterial, antifungal, cytostatic and anti-inflammatory activity and has been used for the treatment of gastric ulcers, burns, and for storage of skin grafts. The present study investigated the antitumor effect of bee honey against Ehrlich ascites tumor in mice and the possible mode of antitumor action. Peroral administration of mice with honey (10, 100 or 1000 mg/ 100 g BW) every other day for 4 weeks before intraperitoneal inoculation with Ehrlich ascites tumor (EAT, 1 x 10(6) cells) increased the number bone marrow cells as well as peritoneal macrophages, but not peripheral blood leukocytes nor splenocytes. The phagocytic function of macrophages as well as the T- and B-cell functions were also increased. Honey pre-treatment also recovered the total lipids, total proteins, as well as liver and kidney enzyme activities in EAT-bearing mice. In vitro studies on EAT cells demonstrated inhibitory effect of honey on tumor cell proliferation, viability % of tumor cells as well as the size of solid tumor. The present results indicate that the preventive treatment with honey is considerably effective against EAT in mice both in vivo and in vitro. The antitumor activity of honey may occur through the activation of macrophages, T-cells and B-cells.

Interactions of lectins with plasma membrane glycoproteins of the Ehrlich ascites carcinoma cell.

Several aspects of the interaction of various lectins with the surface of Ehrlich ascites carcinoma cells are described. The order of agglutinating activity for various lectins is Ricinus communis greater than wheat germ greater than or equal to concanavalin A greater than or equal to soybean greater than Limulus polyphemus. No agglutination was noted for Ulex europaeus. Using 125I-labeled lectins it was determined that there are 1.6 and 7 times as many Ricinus communis lectin binding sites for concanavalin A and soybean lectins. Sodium deoxycholate-solubilized plasma membrane material was subjected to lectin affinity chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The lectin receptors of the plasma membrane appeared to be heterogeneous and some qualitative differences could be discerned among the electrophoretically analyzed material, which bound to and was specifically eluted from the various lectin affinity columns. The characteristics of elution of bound material from individual lectin columns indicated secondary hydrophobic interactions between concanavalin A or wheat germ agglutinin and their respective lectin receptor molecules.

Human endometrial glands synthesize and secrete a high molecular weight mucin-like glycoprotein in a menstrual cycle-dependent fashion. A novel moiety within this Golgi-associated glycoprotein is strongly reactive with IgG antibodies in numerous murine ascites, and has been termed MAG (mouse ascites Golgi). Immunohistochemical staining of 201 endometrial biopsies revealed the following patterns: MAG first appeared in the Golgi on cycle day 5, peaked on day 15, was present on the surface of the luminal epithelium between days 17 and 19, and was no longer detectable after day 19. MAG was also present in cervical, prostate, seminal vesicle, and lacrimal glands, pancreatic acinar cells, gall bladder and bile duct epithelium, and certain cells of the salivary and sweat glands. Interestingly, only tissues from blood group A individuals exhibited this staining. As a common link among all these cell types is the expression of mucins, we speculated that the MAG epitope could be a mucin-associated blood group A-related epitope. This hypothesis was tested by absorption experiments with a variety of glycoconjugates and erythrocytes and by immunoblots of MAG-rich material. The absorption studies demonstrated that only type III porcine mucin (< 1% sialic acid) and blood type A or AB erythrocytes were able to absorb the anti-MAG antibody. Inasmuch as N-acetyl-galactosamine alone, the terminal blood group A carbohydrate, did not block MAG antibody binding, the MAG epitope appears to involve N-acetylgalactosamine plus other determinants. Immunoblots of endometrial extracts and saliva from blood type A individuals revealed MAG-reactive material with a molecular weight > 200 kd under reducing conditions. Because the MAG epitope appears on the endometrial surface during the purported implantation window, we speculate that mucin-like epitopes could play a role in the earliest apposition phases of conceptus-endometrial interaction.

Objectives: With the development of sophisticated instruments for the isolation and elucidation of natural products structures from marine and freshwater organisms, major advances have been made in the discovery of aquatic derived therapeutics. Present investigations were carried out to evaluate cuttlefish (Sepia officinalis) ink extract (IE) and freshwater clam (Coelatura aegyptiaca) extract (CE) for their anticancer and antioxidant activities as compared to 5-flurouracil (5-Fu), in Ehrlich ascites carcinoma (EAC). Methods: Sixty female Swiss albino mice were divided into five groups (n = 12). All groups except group I received EAC cells (5 × 106 cells/mouse i.p.) and this was taken as the 0th day. Group I served as saline control (5 ml/kg 0.9% NaCl w/v p.o). Group II served as EAC control. Rats of groups III, IV and V received IE, CE (200 mg/kg body weight i.p.), and reference drug (5-Fu, 20 mg/kg body weight i.p.), respectively. Results: The reduction in tumor volume, packed cell volume, tumor cell counts and increase in median survival time and percentage increase in life span in treated animals were observed. There was a significant increase in RBC count; Hb content in treated animals and reduction in total WBC count. There was a significant decrease in AST, ALT, ALP and liver MDA levels and increase in GSH, SOD and NO levels were observed in all treated animals. Conclusion: Both IE and CE were effective in inhibiting the tumor growth in ascitic tumor models. The biochemical, antioxidants and histopathological studies were also supported their antitumor properties. PMID:26097537

Inhibition by derivatives of diguanidines of cell proliferation in Ehrlich ascites cells grown in cultures.

The anti-proliferative effects of 1,1'-[(methylethanediylidene)dinitrilo]diguanidine [methylglyoxal bis(guanylhydrazone)] and 1,1'-[(metHYLETHANEDIYLIDENE)dinitrilo]bis-(3-aminoguaNIDINE) HAVE BEEN STUDIED IN Ehrlich ascites carcinoma cells grown in suspension cultures. Both compounds are potent inhibitors of S-adenosyl-L-methionine decarboxylase from the tumour cells. In the presence of putrescine (but not in its absence), the inhibition produced by 1,1'-[methylethanediylidene)dinitrilo]bis-(3-aminoguanadine) was apparently irreversible, as judged by persistent depression of the enzyme activity even after extensive dialysis. The two compounds produced similar increases in adenosylmethionine decarboxylase activity, which resulted from a striking stabilization of the enzyme in cells grown in the presence of the drugs. The inhibitory effect of the two diguanidine derivatives on the synthesis of DNA and protein became evident after an exposure of 4--8 h. At that time, the only change seen in tumour polyamines in cells grown in the presence of the inhibitors was an increase in cellular putrescine. To find out whether the compounds initially interfered with the energy production of the tumour cells, the cultures were grown in the presence of uniformly labelled glucose, and the formation of lactate, as well as the oxidation of the sugar into CO2, were measured. The activation of glycolysis upon dilution of the tumour cells with fresh medium and the subsequent formation of labelled CO2 were siliar in control cells and in cells exposed to methylglyoxal bis(buanylhydrazone), 1,1'-[(methylethanediylidene)dinitrilo]bis-(3-aminoguanidine) or diaminopropanol. Only a marginal decrease in the cellular content of ATP was found in cells exposed to the inhibitors for 24 h. The diguanidine-induced growth inhibition was fully reversed by low concentrations of exogenous polyamines. However, the possibility remained that the reversal by polyamines was due to a decrease of intracellular

Treatment of Ehrlich-ascites-carcinoma-bearing mice with methylglyoxal bis(guanylhydrazone) alone or in combination with 2-difluoromethylornithine greatly enhanced the transfer of intragastrically administered radioactive putrescine and cadaverine into the carcinoma cells. Difluoromethylornithine alone did not have any effect on the accumulation of intestine-derived diamines in the tumour cells. The frequently reported restoration of difluoromethylornithine-induced polyamine depletion on administration of methylglyoxal bis(guanylhydrazone) is in all likelihood attributable to a profound inhibition of intestinal diamine oxidase (EC 1.4.3.6), resulting in an enhanced entry of intestinal (bacterial) diamines into general circulation and finally into tumour cells.

Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings.

The biologic effects and the underlying mechanisms of Ehrlich ascitic tumor (EAT) cells induced by ultrasound were investigated in this study. Cells were subjected to ultrasonic irradiation with a frequency of 2.17 MHz and an intensity of 3 W/cm(2) for variable periods of time. Trypan blue exclusion was used to detect the integrity of cellular membrane; the membrane permeability was investigated by the incorporation of fluorescein isothiocyanate dextran during ultrasound exposure; and the cell membrane ultrastructure changes were observed under a scanning electron microscope. The potential mechanism was estimated from the generation of hydroxyl radicals, the lipid peroxidation levels, and intracellular reactive oxygen radicals production. The cell membrane damage effects induced by ultrasound increased with a prolonged exposure time; the fluorescent rates of the cells irradiated with ultrasound for 30 and 60 seconds were 11.46% and 18.50%, respectively; the amount of hydroxyl radicals in 30 (26.10 U/mL) and 60 seconds (28.47 U/mL) were significantly enhanced, compared with the control group (24.44 U/mL); then, the level of lipid peroxidation was also changed from 0.27 to 0.54 (30 seconds) and 1.21 nmol/mL (60 seconds). Shear forces and free radicals produced by acoustic cavitation may play important roles in these actions.

Ovarian cancers present a mild clinical course when diagnosed early but an aggressive pathway when diagnosed in the peri- and postmenopausal periods. However, the predictability of tumor progression is stochastic and is difficult to predict. In the present study, we hypothesized to examine the key pathways that are dysregulated to promote epithelial-mesenchymal transition in serous ovarian carcinoma. Examination of these steps would help to identify ascitic fluid with cells poised for metastasis or otherwise. We focused on examining the Akt2 expression, mainly because of its report as being overamplified in the aggressive variants of ovarian cancer, as well as TGFbeta-sensitivity of Akt2 that forms the key basis for metastasis initiation of most kinds of carcinoma. We obtained primary ovarian carcinoma samples as well as ascitic fluid and distantly metastatic ovarian carcinoma to examine the expression of Akt2. The results of the study demonstrated that in malignant exfoliated ovarian cancer cells, Smad4 expression was tremendously increased in the nuclei, suggesting nuclear translocation of Smad, which thereafter may have activated ZEB2, and thereafter genomically affected the expression of E-cadherin, myosin II, and vimentin, key components for initiating and sustaining metastasis. All of these may have been stimulated by increased cellular expression of Akt2 in metastatic variants of the serous ovarian carcinoma. The reliance on Akt2 and TGF beta signaling may also potentiate the case for Akt inhibitors or small molecule inhibitors of TGFbeta signaling like doxycycline as adjunct chemotherapy in serous ovarian carcinoma, especially the metastatic variants.

Letrozole (LTZ) incorporated PLGA nanoparticles were prepared by solvent displacement technique and characterized by transmission electron microscopy, poly-dispersity index and zeta potential measurement. Radiolabeling of free LTZ and LTZ-loaded PLGA NPs was performed with technetium-99m with high labeling efficiency. The labeled complex showed good in vitro stability as verified by DTPA challenge test. The labeled complexes also showed significant in vivo stability when incubated in rat serum for 24 h. Biodistribution studies of (99m)Tc-labeled complexes were performed after intravenous administration in normal mice and Ehrlich Ascites tumor bearing mice. Compared to free LTZ, LTZ-loaded PLGA NPs exhibited significantly lower uptake by the organs of RES. The tumor concentration of LTZ-loaded PLGA NPs was 4.65 times higher than that of free LTZ at 4 h post-injection. This study indicates the capability of PLGA nanopartcles in enhancing the tumor uptake of letrozole. Copyright 2010 Elsevier B.V. All rights reserved.

Development and characteristics of a subline of Ehrlich ascites carcinoma cells persistently resistant to 5-fluoro-2'-deoxyuridine.

A subline of Ehrlich ascites carcinoma (EAC) cells resistant to 5-fluoro-2'-deoxy-uridine (FdUrd) was developed by continuous exposure to progressively increasing concentrations of the drug (35-75 mg/kg per day) during 15 passages through mice. Since then, the EAC cells have been retransplanted more than 80 times through drug-untreated mice and continue to be resistant. After adaptation to growth in suspension culture the drug-adapted cells were 1000 times more resistant to FdUrd in comparison with parental ones, and remained near-tetraploid with doubling time longer than in parental line. The activity of thymidine kinase was deeply depressed (100-fold) whereas that of thymidylate synthetase several-fold increased in the resistant EAC cells, both grown in vivo and in vitro.

Systemic lupus erythematosus (SLE) is an autoimmune disease, involving multiple organs. Diverse manifestations may obscure the diagnosis and confuse our thinking process, especially when few clues are present at the beginning. Serositis is one of the various presentations, and the presence of lupus erythematosus (LE) cell in body fluid may be a hint for the final diagnosis of SLE. Herein, we present a young female patient diagnosed of SLE with initial presentation of lupus peritonitis. Finding of LE cell in ascites prompted us for immunologic survey. Diagnosis of SLE was confirmed with high titer of anti-nuclear antibody and antibody to double-stranded DNA. Cytologic examination of body fluid is mainly useful in detecting malignant cells, but high specificity of this marker aids in early diagnosis of SLE.

Conditions are described for the production of 0.3 to 0.7 NIH mouse reference standard units of interferon per cell from Ehrlich ascites tumour cells cultured as monolayers and induced by infection with Newcastle disease virus (NDV). Inclusion of theophylline (6 mM) in the medium increased the interferon yield three to four times. Cells infected with NDV started to lyse at about 15 p.i., but infected, theophylline-treated cells lysed only 24 p.i. Several other methylxanthines (e.g. theobromine, caffeine and isobutylmethylxanthine) when tested a concentrations similar to that of theophylline, did not boost interferon production. Dibutyryl cyclic AMP (10(-10) to 10(-2)M) did not substitute for theophylline in increasing interferon production, and, if used together with theophylline, did not cause further enhancement.

The Dengue Score is a model for predicting pleural effusion and/or ascites and uses the hematocrit (Hct), albumin concentration, platelet count and aspartate aminotransferase (AST) ratio as independent variables. As this metric has not been validated, we conducted a study to validate the Dengue Score and assess its clinical application. A retrospective study was performed at a private hospital in Jakarta, Indonesia. Patients with dengue infection hospitalized from January 2011 through March 2016 were included. The Dengue Score was calculated using four parameters: Hct increase≥15.1%, serum albumin≤3.49 mg/dL, platelet count≤49,500/μL and AST ratio ≥ 2.51. Each parameter was scored as 1 if present and 0 if absent. To validate the Dengue Score, goodness-of-fit was used to assess calibration, and the area under the receiver operating characteristic curve (AROC) was used to assess discrimination. Associations between clinical parameters and Dengue Score groups were determined by bivariate analysis. A total of 207 patients were included in this study. The calibration of the Dengue Score was acceptable (Hosmer-Lemeshow test, p = 0.11), and the score's discriminative ability was good (AROC = 0.88 (95% CI: 0.83-0.92)). At a cutoff of ≥2, the Dengue Score had a positive predictive value (PPV) of 79.03% and a negative predictive value (NPV) of 90.36% for the diagnostic prediction of pleural effusion and/or ascites. Compared with the Dengue Score ≤ 1 group, the Dengue Score = 2 group was significantly associated with hemoconcentration> 20% (p = 0.029), severe thrombocytopenia (p = 0.029), and increased length of hospital stay (p = 0.003). Compared with the Dengue Score = 2 group, the Dengue Score ≥ 3 group was significantly associated with hemoconcentration> 20% (p = 0.001), severe thrombocytopenia (p = 0.024), severe dengue (p = 0.039), and increased length of hospital stay (p = 0.011).

Ehrlich ascites carcinoma thymidylate synthetase was purified to electrophoretic homogeneity by affinity chromatography on 10-formyl-5,8-dideazofolate-ethyl-Sepharose. Electrophoretic analysis of the formation of the enzyme-5-fluorodeoxyuridylate-5,10-methylenetetrahydrofolate complexes showed the presence of two binding sites for 5-fluorodeoxyuridylate on the enzyme molecule. Molecular weight of the native enzyme was found to be 78,5000, whereas that of its monomer was 38, 500. The apparent Michaelis constants for dUMP and (+/-)-L-5,10-methylenetetrahydrofolate were 1.3 +/- 0.4 and 32.2 +/- 0.7 micrometers respectively. Phosphate acted as a weak inhibitor, competitive toward dUMP. The enzyme reaction exhibited a temperature-dependent change of activation energy, reflected in the binding affinity of dUMP, with a transitional temperature of 35.8 degrees. Both Mg2+ and MgATP2- were strong activators of the enzyme, MgATP2- being more effective.

Bi-212 is an alpha-emitting radionuclide being investigated as a therapeutic agent in the intraperitoneal treatment of micrometastatic ovarian carcinoma. In evaluating a new therapeutic modality, cell-survival studies are often used as a means of quantifying the biological effects of radiation. In this analysis, Ehrlich ascites cells were irradiated under conditions similar to therapy in various concentrations of Bi-212. Immediately following irradiation, a cell survival assay was performed in which cells were plated and colonies were counted after 10--14 days. Both a macrodosimetric and a microdosimetric approach were used in analyzing these data. These models used as input the fraction ofmore » activity within the cell and in solution, the distribution of cell sizes, and the variation of LET along individual alpha-particle tracks. The results indicate that the energy deposited within the nucleus varies significantly among individual cells. There is a small fraction of cell nuclei which receive no hits, while the remaining cells receive energy depositions which can differ significantly from the mean value. These dosimetric parameters are correlated with measured cell survival and will be a useful predictor of outcome for therapeutic doses.« less

The synergistic effect of methotrexate (at concentrations between 3. 1 and 100 nM) and its combinations with caffeine (618 microM) and/or hyperthermia (42 degreesC for 2 h) on the frequency of sister chromatid exchanges (SCEs), the proliferating rate index and the mitotic index in cultured human lymphocytes, was examined. Also, the in vivo antineoplastic effects of methotrexate (at a concentration of 0.45 microg/g body weight) and its combination with caffeine (120 microg/g body weight), both on the survival time and the increase of the weight of tumor of BALB/c mice inoculated with Ehrlich ascites tumor cells was examined in the present study. The results indicated that: (a) the triple combination of methotrexate, caffeine and hyperthermia synergistically increased the levels of SCEs and exerted cytostatic and cytotoxic action and (b) the combination of methotrexate and caffeine significantly increased the survival span of the mice inoculated with Ehrlich ascites tumor cells and reduced the increase of the weight of their tumors at rates higher than in the case of methotrexate by itself. It is suggested that the above triple combination (methotrexate plus caffeine plus hyperthermia) could achieve increased effectiveness of methotrexate, better therapy results, and could be successfully applied in the treatment of various types of cancer.

Abstract Rationale: Malignant ascites (MA) is one of the poor prognostic factors for advanced pancreatic cancer and can bring about serious symptoms. The improvement of quality of life for patients is priority. However, there is no standard method for the treatment for pancreatic cancer-mediated MA. Apatinib is a novel and highly selective tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2. There are no reports of concurrent apatinib with gemcitabine in patients with pancreatic cancer-mediated MA. Patient concerns: Herein, we presented a 64-year-old man patient who visited hospital due to abdominal pain for 1 month. Diagnoses: He was initially diagnosed with pancreatic cancer and his first symptom was MA. Interventions: After failing in tube drainage and gemcitabine therapy, the patient received gemcitabine combined apatinib orally and after administrated 1 month, the MA was evaluated as nearly clear response according to the RECIST 1.1 standard, and without further need of paracentesis. The CEA and CA199 reached the lowest level after administrating for 2.5 months during the treatment process. Outcomes: 10.5 months following apatinib administration, the patient achieved a progression-free survival for more than 11 months. Hypertension (grade IV), hand-foot syndrome (grade I) and proteinuria (grade II) were observed. Lessons: It indicated that apatinib concurrent gemcitabine may be a superior choice for pancreatic cancer-mediated MA. Further clinical trials required to confirm its efficacy and safety.

Objective To determine the hepatoprotective effect of acetone semicarbazone (ASC) in vivo in normal and Ehrlich ascites carcinoma (EAC) bearing male Swiss albino mice. Methods Drug-induced changes in biochemical and behavioral parameters at dose of 2.0 mg/kg body weight for 14 d and nullifying the toxicity induced by EAC cells were studied. The histopathology studies of the protective effects of ASC on vital organs were also assessed. Results The administration of ASC made insignificant changes in body weight and behavioral (salivation, diarrhea, muscular numbness) changes during treatment period due to minor toxicity were minimized after the treatment in normal mice. The biochemical parameters, including serum glutamate pyruvate transaminase, glutamate oxaloactate transaminase, alkaline phosphatase, serum glucose, cholesterol, urea, triglyceride and billirubin changed modestly in normal mice receiving ASC. Though the treatment continued, these values gradually decreased to normal level after the treatment. In EAC bearing mice, the toxic effects due to EAC cells in all cases were nullified by treatment with the ASC. Significant abnormalities were not detected in histology of the various organs of the normal mice treated with ASC. Conclusions ASC can, therefore, be considered safe in formulating novel anticancer drug, as it exhibits strong protective effect against EAC cell bearing mice. PMID:23593588

Biosynthetic maturation of an ascites tumor cell surface sialomucin. Evidence for O-glycosylation of cell surface glycoprotein by the addition of new oligosaccharides during recycling.

Previous biosynthetic studies of the ascites 13762 rat mammary adenocarcinoma cell surface sialomucin ASGP-1 (ascites sialoglycoprotein-1) showed that it is synthesized initially as a poorly glycosylated immature form, which is converted to a larger premature form (t1/2 30 min) and more slowly to the mature glycoprotein (t1/2 greater than 4 h). In the present study O-glycosylation of ASGP-1 polypeptide is shown to occur in two phases: an early phase complete in less than 30 min, which corresponds to the synthesis of the premature form, and a later phase that continues for hours and corresponds to the synthesis of the mature form. Pulse-chase labeling studies indicate that 95% of the ASGP-1 has moved to the cell surface in 2 h. Since transit to the cell surface is faster than the slow phase of addition of new oligosaccharides, some new oligosaccharides must be added after ASGP-1 has reached the cell surface. Initiation of new oligosaccharides on cell surface ASGP-1 was demonstrated directly using a biotinylation procedure to identify cell surface molecules. Glucosamine labeling of biotinylated ASGP-1 was shown to occur on galactosamine residues, which are linked to the polypeptide, establishing the addition of new oligosaccharides to the cell surface molecules. Finally, resialylation studies indicate that ASGP-1 rapidly recycles through a sialylating compartment. From these results we propose that ASGP-1 reaches the cell surface in an incompletely glycosylated state and that additional oligosaccharides are added to the glycoprotein in a second process involving recycling.

Rats were divided into 8 groups, 9 rats in each group. Histological study with assessment of therapeutic pathomorphosis in TOT and immunohistochemical study has been carried out. Survival of animals in the studied groups has been evaluated. Among animals treated in regimen of monotherapy, the most pronounced antiangiogenic activity in TOT has been observed on application of hormonal drugs (triptorelin - 39.4 ± 1.9 and exemestane - 33.9 ± 1.4%; р = 0.003), the highest grade of treatment pathomorphosis in TOT has been observed at treatment with cisplatin (11.7%; р = 0.001). Combination of triptorelin and exemestane has amplified antiangiogenic activity in TOT (12.2 ± 0.9%; р = 0.001), but has not significantly changed rates of pathomorphosis (22.1 ± 0.4%; р=0.005) and survival of animals (32.2%; р = 0.007) as compared with the same rates in rats treated with hormonal drugs in monotherapy. Significant correlation between VEGF expression and pathomorphosis has been established (relative part of viable tumor tissue (RPVTT)) in TOT (r = 0.712; р = 0.001), as well as between RPVTT and life-span of animals (r = -0.320; р = 0.007). However, lack of correlation between VEGF expression in cells of TOT and survival of rats has been determined (r = -0.194; р = 0.11). Combination of cytostatic agent with triptorelin or exemestane has demonstrated significantly high rates of therapeutic

A hypothesis that the ionic composition of drinking water might affect development of the ascites syndrome in broilers was investigated in two trials. The first trial comprised four groups of 650 male chicks. A control treatment was normal tap water and the other three treatments comprised the addition to the tap water of 1,000 mg/L sodium as NaCl, 5,000 mg/L NH4Cl, or 5,000 mg/L KHCO3, supplied from age 2 to 47 d. At Day 28, equally sized subsets of these groups were moved to individual cages, where they received a severe exposure to ambient cold. The development of the ascites syndrome was monitored by measurements of hematocrit and arterial blood oxygen saturation (PaO2) by oximetry, body weight, and examination of dead birds for cause of death. Mortality from ascites in cold-exposed birds from Days 28 to 47 was 28, 48, 40, and 16% in the tap water, NaCl, NH4Cl, and KHCO3 groups, respectively; only the NaCl mortality was significantly different from the tap water mortality. The KHCO3 treatment increased PaO2 (compared with tap water treatment) at Day 28 by 5.5% and at Day 35 by 10.5%, but not at Day 42. The KHCO3 caused a reduction in body weight, which was 13% less than the tap water group at Day 42, probably due to a chronic toxicity. The second trial specifically examined the same parameters with lower water levels of KHCO3 (3,000 and 1,000 mg/L), in comparison to a 10% feed restriction protocol, in order to clarify whether the increased PaO2 was due to a specific effect of the KHCO3 or was a metabolic manifestation of a reduced growth rate. The 3,000 mg/L KHCO3 treatment had no effect on PaO2, but the 1,000 mg/L treatment augmented PaO2 by 5.3% at Day 35 (but not at Days 28 or 42), without reducing the final body weight. The feed restriction group showed an elevated PaO2 of 5.4% at Day 35 (but not at Days 28 or 42), with no reduction in the final body weight. The inclusion of 1,000 mg/L of KHCO3 into the drinking water of broilers or a temporary 10% feed

1. A strain of Ehrlich ascites-tumour cells that showed little inhibition of growth in the presence of 6-mercaptopurine accumulated less than 5% as much 6-thioinosine 5′-phosphate in vivo, in the presence of 6-mercaptopurine, as did the sensitive strain from which it was derived. 2. Specific activities of the phosphoribosyltransferases that convert adenine, guanine, hypoxanthine and 6-mercaptopurine into AMP, GMP, IMP and 6-thioinosine 5′-phosphate were similar in extracts of the resistant and the sensitive cells. 3. As found previously with sensitive cells, 6-mercaptopurine is a competitive inhibitor of guanine phosphoribosyltransferase and hypoxanthine phosphoribosyltransferase from the resistant cells and does not inhibit the adenine phosphoribosyltransferase from these cells. Michaelis constants and inhibitor constants of the purine phosphoribosyltransferases from resistant cells did not differ significantly from those measured with the corresponding enzymes from sensitive cells. 4. Resistance to 6-mercaptopurine in this case is probably not due to qualitative or quantitative changes in these transferases. PMID:14342251

To construct the cDNA library of the ascites tumor cells of ovarian cancer, which can be used to screen the related antigen for the early diagnosis of ovarian cancer and therapeutic targets of immune treatment. Four cases of ovarian serous cystadenocarcinoma, two cases of ovarian mucinous cystadenocarcinoma, and two cases of ovarian endometrial carcinoma in patients with ascitic tumor cells which were used to construct the cDNA library. To screen the ovarian cancer antigen gene, evaluate the enzyme, and analyze nucleotide sequence, serological analysis of recombinant tumor cDNA expression libraries (SEREX) and suppression subtractive hybridization technique (SSH) techniques were utilized. The detection method of recombinant expression-based serological mini-arrays (SMARTA) was used to detect the ovarian cancer antigen and the positive reaction of 105 cases of ovarian cancer patients and 105 normal women's autoantibodies correspondingly in serum. After two rounds of serologic screening and glycosides sequencing analysis, 59 candidates of ovarian cancer antigen gene fragments were finally identified, which corresponded to 50 genes. They were then divided into six categories: (1) the homologous genes which related to the known ovarian cancer genes, such as BARD 1 gene, etc; (2) the homologous genes which were associated with other tumors, such as TM4SFI gene, etc; (3) the genes which were expressed in a special organization, such as ILF3, FXR1 gene, etc; (4) the genes which were the same with some protein genes of special function, such as TIZ, ClD gene; (5) the homologous genes which possessed the same source with embryonic genes, such as PKHD1 gene, etc; (6) the remaining genes were the unknown genes without the homologous sequence in the gene pool, such as OV-189 genes. SEREX technology combined with SSH method is an effective research strategy which can filter tumor antigen with high specific character; the corresponding autoantibodies of TM4SFl, ClD, TIZ, BARDI

The aim of the present investigation was to evaluate Zingiber officinale paste against Dalton's lymphoma ascites (DLA)-induced tumours in Swiss albino mice. Experimental animals received Z. officinale paste (low dose 100 mg/kg bw and high dose 500 mg/kg bw) orally for eight alternative days. Treatment with Z. officinale paste showed significant increase in haemoglobin level and decrease in aspartate amino transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (γ-GT) level. Z. officinale paste reduced the inflammatory mediators and cytokine levels, such as inducible nitric oxide (iNOS), tumour necrosis factor level (TNF-α) and interleukin-1β (IL-1β). Treatment with Z. officinale paste also significantly increased the antioxidant enzyme level, such as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and glutathione transferase (GST), and decreased the lipid peroxidation. Treatment also increased the vitamin C and E levels in treated animals compared with the DLA-bearing host. Histopathological studies also confirmed the protective influence of Z. officinale paste against DLA. The present study suggested that Z. officinale paste could be used as natural spice and a potent antitumour agent.

ABSTRACT The present study was carried out to assess the antitumor effect of venomous peptide from the cephalopod Octopus aegina on Ehrlich's ascites carcinoma (EAC). Male albino Swiss mice were used in the present study. Four groups of animals were treated with three doses of the sublethal dose of venom, 15, 75, and 150 mug/kg body weight (intraperitoneal injection), along with the standard drug 5-fluorouracil (20 mg/kg b.w.). After 10 days of treatment, six animals from each group were sacrificed for the biochemical analysis and the rest were left to calculate the mean survival time. In EAC-bearing mice, mean lifespan, tumor volume, hemoglobin, red blood cells, and lymphocytes were significantly decreased when compared to the normal animals. While body weight, neutrophils, and viable tumor cell count were increased in the EAC-bearing mice, these changes were brought back to near normal levels in different treatment groups. The macromolecule concentration of peritoneal cells, such as DNA, RNA, and protein, were altered in the EAC-bearing mice and observed to be near normal in the treatment groups. The caspase-3 activity was significantly increased in the peritoneal cells of the treatment groups when compared to the EAC-bearing mice. The role of apoptotic cascade in EAC cell death was confirmed by the DNA fragmentation on agarose gel. Apart from the antitumor effect, octopus venom reduced the tumor burden on the liver and altered the changes in the activities of alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP). Therefore, the venom from O. aegina has a potential antitumor effect on the EAC-bearing mice.

Yellowtail ascites virus (YAV) is an aquabirnavirus that causes ascites in yellowtail, a fish often used in sushi. Segment A of the YAV genome codes for a polyprotein (pVP2-VP4-VP3), where processing by its own VP4 protease yields the capsid protein precursor pVP2, the ribonucleoprotein-forming VP3, and free VP4. VP4 protease utilizes the rarely observed serine-lysine catalytic dyad mechanism. Here we have confirmed the existence of an internal cleavage site, preceding the VP4/VP3 cleavage site. The resulting C-terminally truncated enzyme (ending at Ala(716)) is active, as shown by a trans full-length VP4 cleavage assay and a fluorometric peptide cleavage assay. We present a crystal structure of a native active site YAV VP4 with the internal cleavage site trapped as trans product complexes and trans acyl-enzyme complexes. The acyl-enzyme complexes confirm directly the role of Ser(633) as the nucleophile. A crystal structure of the lysine general base mutant (K674A) reveals the acyl-enzyme and empty binding site states of VP4, which allows for the observation of structural changes upon substrate or product binding. These snapshots of three different stages in the VP4 protease reaction mechanism will aid in the design of anti-birnavirus compounds, provide insight into previous site-directed mutagenesis results, and contribute to understanding of the serine-lysine dyad protease mechanism. In addition, we have discovered that this protease contains a channel that leads from the enzyme surface (adjacent to the substrate binding groove) to the active site and the deacylating water.

Naturally occurring pterostilbene (PTER) and isothiocyanate (ITC) attract great attention due to their wide range of biological properties, including anti-cancer, anti-leukemic, anti-bacterial and anti-inflammatory activities. A novel class of hybrid compound synthesized by introducing an ITC moiety on PTER backbone was evaluated for its anti-cancer efficacy in hormone-dependent breast cancer cell line (MCF-7) in vitro and Ehrlich ascitic tumor bearing mice model in vivo. The novel hybrid molecule showed significant in vitro anti-cancer activity (IC{sub 50}=25±0.38) when compared to reference compound PTER (IC{sub 50}=65±0.42). The conjugate molecule induced both S and G2/M phase cell cycle arrest as indicated by flowmore » cytometry analysis. In addition, the conjugate induced cell death was characterized by changes in cell morphology, DNA fragmentation, activation of caspase-9, release of cytochrome-c into cytosol and increased Bax: Bcl-2 ratio. The conjugate also suppressed the phosphorylation of Akt and ERK. The conjugate induced cell death was significantly increased in presence of A6730 (a potent Akt1/2 kinase inhibitor) and PD98059 (a specific ERK inhibitor). Moreover, the conjugated PTER inhibited tumor growth in Ehrlich ascitic cell induced tumor bearing mice as observed by reduction in tumor volume compared to untreated animals. Collectively, the pro-apoptotic effect of conjugate is mediated through the activation of caspases, and is correlated with the blockade of the Akt and ERK signaling pathways in MCF-7 cells. - Highlights: • Conjugate was prepared by appending isothiocyanate moiety on pterostilbene backbone. • Conjugate showed anticancer effects at comparatively lower dose than pterostilbene. • Conjugate caused blockage of the Akt and ERK signaling pathways in MCF-7 cells. • Conjugate significantly reduced solid tumor volume as compared to pterostilbene.« less

Cisplatin (CP) is a widely used cytotoxic agent against cancer, and high doses of CP have been known to cause nephrotoxicity and hepatotoxicity. Some reports claim that antioxidants can reduce CP-induced toxicity. This study investigated the hepatoprotective, nephroprotective, and antioxidant activity of Urtica dioica L methanolic extract (UDME) against CP toxicity in Erhlich ascites tumor (EAT)-bearing mice. Levels of serum hepatic enzymes, renal function markers, and oxidant/antioxidant parameters of liver tissue were measured. Mice were inoculated with EAT on day 0 and treated with nothing else for 24 hours. After a single dose of CP administration on day 1, the extract was given at the doses of 50, 100, 200, and 400 mg/kg body weight daily during 6 days. Almost all doses of UDME performed a significant (P < 0.05) preventive role against CP toxicity by decreasing aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, blood urea nitrogen, creatinine, lipid peroxidation, protein oxidation levels, and myeloperoxidase activity, as well as increasing reduced glutathione content, superoxide dismutase, catalase, glutathione S-transferase, and glutathione peroxidase activities. This suggests that UDME has a protective capacity and antioxidant activity against CP toxicity in EAT-bearing mice, probably by promoting antioxidative defense systems.

Malignant ascites (MA) is one of the poor prognostic factors for advanced pancreatic cancer and can bring about serious symptoms. The improvement of quality of life for patients is priority. However, there is no standard method for the treatment for pancreatic cancer-mediated MA. Apatinib is a novel and highly selective tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2. There are no reports of concurrent apatinib with gemcitabine in patients with pancreatic cancer-mediated MA. Herein, we presented a 64-year-old man patient who visited hospital due to abdominal pain for 1 month. He was initially diagnosed with pancreatic cancer and his first symptom was MA. After failing in tube drainage and gemcitabine therapy, the patient received gemcitabine combined apatinib orally and after administrated 1 month, the MA was evaluated as nearly clear response according to the RECIST 1.1 standard, and without further need of paracentesis. The CEA and CA199 reached the lowest level after administrating for 2.5 months during the treatment process. 10.5 months following apatinib administration, the patient achieved a progression-free survival for more than 11 months. Hypertension (grade IV), hand-foot syndrome (grade I) and proteinuria (grade II) were observed. It indicated that apatinib concurrent gemcitabine may be a superior choice for pancreatic cancer-mediated MA. Further clinical trials required to confirm its efficacy and safety.

In this study, we evaluated the carcinostatic effects of combined ascorbic acid (AsA) and a capacitive-resistive electric transfer (CRet) hyperthermic apparatus-induced hyperthermic treatment on Ehrlich ascites tumor (EAT) cells. EAT cells were exposed to various AsA (0-10 mM) concentrations for 1 h; they subsequently underwent CRet treatment for 15 min at 42 °C. Cell viability was assessed by the WST-8 assay 24 h after the combined treatment. Reactive oxygen species involvement was evaluated using catalase and tempol; caspase-3/7 activation was determined by their fluorescent substrates; cell proliferation were estimated by time-lapse observation. The effect on the cell cycle was analyzed by flow cytometry. Combined AsA and CRet treatment synergistically suppressed cell viability compared with either treatment alone, and these synergistically carcinostatic effects were evident even at noncytotoxic concentrations of AsA alone (≤ 2 mM). The carcinostatic effects of combined AsA and CRet treatment were attenuated in a dose-dependent manner by catalase addition, but not by the superoxide anion radical scavenger tempol. Time-lapse observation revealed that combined AsA and CRet treatment activated caspase-3/7 at 10-24 h after treatment, accompanied by significant cell growth suppression. Cell cycle analysis revealed that the rate of sub-G1-phase (apoptotic) cells was drastically increased at 12 h and 24 h, and that the G2/M-phase cells gradually increased at 6-24 h after treatment. These results indicate that combined AsA and CRet treatment synergistically inhibits EAT cell growth through G2/M arrest and apoptosis induction via H2O2 generation at lower AsA concentrations; this carcinostatic effect cannot be exerted by AsA alone.

The influence of boric acid, a boron carrier, on Ehrlich ascites carcinoma (EAC) cell-bearing mice was investigated in view of its importance in the boron neutron capture therapy and the influence of boron on proliferation and progression of cancer cells mediated by proteoglycans and collagen. The present study included the evaluation of boric acid for the effects on total count and viability of EAC cells in addition to their non-protein sulfhydryls (NP-SH) and malondialdehyde (MDA) contents as parameters for conjugative detoxication potency and possible oxidative damage. The EAC cell-bearing animals were also observed for the effect on survival, body weight changes, and histopathological evaluation of the tumors grown at the site of inoculation. The treatment with boric acid significantly increased the total number of peritoneal EAC cells and their viability. A significant increase in the body weight was observed that dose-dependently reached plateau levels by 20 days of treatment. Conversely, a reduction in the duration of survival of these animals was evident with the same protocol. Boric acid treatment resulted in a decrease in NP-SH contents with a concomitant increase in MDA levels in EAC cells as revealed by the results of the biochemical analysis. These data are supported by our results on histopathological investigations, which apparently showed fast growth, in addition to several mitotic figures and mixed inflammatory reaction, after treatment with boric acid. It seems likely that a particular combination of properties of boric acid, rather than a single characteristic alone, will provide useful information on the use of this boron carrier in neutron capture therapy.

The purpose of this investigation was to evaluate the antiproliferative and apoptogenic mechanistic studies of methanol extract of Anthocephalus cadamba (MEAC) on Dalton’s lymphoma ascites (DLA) cells treated mice. Determination of antiproliferative activity was performed by using different DLA cells (2×106 cells, i.p.) inoculated mice groups (n = 12). Groups were treated for 14 consecutive days with MEAC at the doses of 200 and 400 mg/Kg b.w. respectively. The mechanism of antiproliferation activity of MEAC was investigated through morphological studies by acridine orange (AO)/ethidium bromide (EB) double staining method. Comet assay was estimated to check the DNA damage induced apoptosis property. Furthermore, flow cytometry (FACS) was used to quantitatively detect the apoptotic rate by double labeling techniques using Annexin-V FITC/propidium iodide staining analysis and apoptotic proteins expression done by western blotting assay method. MEAC exhibited significant (p<0.01) decrease the tumor volume, viable cell count, tumor weight and elevated the life span of DLA tumor bearing mice. Analysis of AO/EB staining and flow cytometry showed that MEAC possessed apoptosis induced antitumor activity on DLA cells in a dose dependant manner. Dose dependent induction of DNA damage on DLA cells were observed after MEAC treatment, which was evident from the appearance of comet tail length. Pro-apoptotic gene, Bax was up-regulated and down-regulation of the Bcl-2/Bax ratio, suggesting that Bcl-2 family involved in the control of apoptosis. Experimental results revealed that MEAC possess potent antitumor activity via induction of cancer cell apoptosis mechanism. PMID:27980586

To investigate experimentally the possible antitumor effect of methanol extract (ME) of Calotropis gigantea L. (C. gigantean) root bark and its petroleum ether (PEF) and chloroform (CF) soluble fractions against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. The effects of ME (10 and 20 mg/kg), PEF (40 and 80 mg/kg) and CF (20 and 40 mg/kg) on the growth of EAC and life span of EAC bearing mice were studied. Hematological profile and biochemical parameters (SALP, SGPT and SGOT) were also estimated. Results of in vivo study showed a significant decrease in viable tumor cell count and a significant increase of life span in the ME and CF treated group compared to untreated one. The life span of ME and CF treated animals was significantly (P<0.05) increased by 43.90% (20 mg ME/kg) and 57.07% (40 mg CF/kg). ME and CF brought back the hematological parameter more or less normal level. ME and CF also restored the altered levels of serum alkaline phosphatase (SALP) and serum glutamate oxaloacetate transaminase (SGOT). Methanol extract (ME) of C. gigantea root bark and its chloroform soluble fraction (CF) possesses significant antitumor activity. Copyright © 2011 Hainan Medical College. Published by Elsevier B.V.

Intraperitoneal injection of ovine prolactin (100 micrograms/d) in Fischer 344 rats bearing transplantable 13762 mammary ascites tumor (MAT) cells modifies the surface charge density and membrane fluidity of the tumor cells. In each of five experiments the mean electrophoretic mobility (epm) of MAT cells taken from prolactin-treated rats was significantly lower than that of cells from nonhormone-treated controls. Prolactin concentrations were increased in vivo by (a) direct intraperitoneal injection of ovine prolactin; (b) subcutaneous implantation of diethylstilbestrol-containing silastic capsules to produce pituitary prolactin secreting tumors; or (c) a single subcutaneous injection of polyestradiol phosphate, a long-acting estrogen. In an effort to establish that the prolactin effect was a direct one, two in vivo protocols were used: (a) MAT cells were coincubated with anterior pituitary halves obtained from nontumor-bearing littermates; or (b) rat or ovine prolactin was added to serum-free culture media containing MAT cells. In both protocols, the epm of the prolactin-treated cells was significantly lower. The isoelectric focusing pH of whole cells was increased by prolactin treatment from 4.93 to 5.12, consistent with a reduction in the number of surface carboxyl groups. The fluidity of membranes of treated cells was drastically increased, as measured by spin-label probe rotation rates. These combined results imply that the hormone exerts its effect by stimulating events in the cell that lead to a reduction of the average density of carboxylic acid residues on the tumor cell surface.

Calcium-ion transport by intact Ehrlich ascites-tumour cells. Role of respiratory substrates, Pi and temperature.

PubMed

Charlton, R R; Wenner, C E

1. The interaction of intact Ehrlich ascites-tumour cells with Ca2+ at 37 degrees C consists of Ca2+ uptake followed by efflux from the cells. Under optimum conditions, two or three cycles of uptake and efflux are observed in the first 15 min after Ca2+ addition. 2. The respiratory substrates malate, succinate and ascorbate plus p-phenylenediamine support Ca2+ uptake. Ca2+ uptake at 37 degrees C is sensitive to the respiratory inhibitors rotenone and antimycin A when appropriate substrates are present. Ca2+ uptake and retention are inhibited by the uncoupler S-13. 3. Increasing extracellular Pi (12 to 30 mM) stimulates uncoupler-sensitive Ca2+ uptake, which reaches a maximum extent of 15 nmol/mg of protein when supported by succinate respiration. Ca2+ efflux is partially inhibited at 30 mM-Pi. 4. Optimum Ca2+ uptake occurs in the presence of succinate and Pi, suggesting that availability of substrate and Pi are rate-limiting. K. Ca2+ uptake occurs at 4 degrees C and is sensitive to uncouplers and oligomycin. Ca2+ efflux at this temperature is minimal. These data are consistent with a model in which passive diffusion of Ca2+ through the plasma membrane is followed by active uptake by the mitochondria. Ca2+ uptake is supported by substrates entering respiration at all three energy-coupling sites. Ca2+ efflux appears to be an active process with a high temperature coefficient.

An expression of calpain and caspase-1 as well as the concomitant ultrastructural alterations were investigated during necrosis of the mouse Ehrlich ascites carcinoma. The calpain expression was registered at 0 h and 1 h although caspase-1 did not induce any signals during these time periods. The rise of the cytoplasmic lytic zones contacted by calpain antibodies was identified as a morphologic event corresponding to the expression of calpain. Lytic zone's distribution followed by the appearance of the calpain/caspase-1 clusters assigned for lysis of the Golgi vesicles and ER. Also, the microapocrine secretion of the vesicles containing the calpain/caspase-1 clusters was detected. Further, the lysis of the plasma membrane occurred due to progression of intracellular lysis. Rupture of the plasma membrane resulted in the termination of secretion and dissemination of cell contents. The nuclei still had their normal shape. Nuclear lysis continued to rise with intranuclear lytic zones, of which the progression was accompanied with the presence of calpain/caspase-1 clusters. The data contribute to the concept of the initial role of calpain for tumor cell destruction, provide first evidence of the calpain/caspase-1 pathway in tumor cells, and highlight microapocrine secretion as a possible tumor cell death signalling mechanism.

The growth-related protein p23 of the Ehrlich ascites tumor (EAT) is preferentially expressed in the exponentially growing tumor; its synthesis is translationally controlled. p23 mRNA is efficiently translated in the wheat germ cell-free lysate. In contrast, p23 mRNA present in poly(A)+RNA isolated from EAT is not translated in cell-free systems of EAT and reticulocytes. Moreover, translation of a p23 transcript is inhibited in the presence of total poly(A)+RNA. This inhibition is abolished by the removal of the 5'-UTR of the p23 transcript. Solution hybridization/RNase protection experiments point to the presence of a nucleotide sequence complementary to the 5'-UTR of p23 mRNA which might be involved in p23 mRNA inhibition.

To investigate the chemopreventive efficacy of the Indian medicinal plant Acanthus ilicifolius L Acanthaceae in a transplantable Ehrlich ascites carcinoma (EAC)-bearing murine model. Male Swiss albino mice were divided into four groups: Group A was the untreated normal control; Group B was the EAC control mice group that received serial, intraperitoneal (ip) inoculations of rapidly proliferating 2 x 10(5) viable EAC cells in 0.2 mL of sterile phosphate buffered saline; Group C was the plant extract-treated group that received the aqueous leaf extract (ALE) of the plant at a dose of 2.5 mg/kg body weight by single ip injections, once daily for 10, 20 and 30 consecutive days following tumour inoculation (ALE control); and Group D was the EAC + ALE-treatment group. The chemopreventive potential of the ALE was evaluated in a murine model by studying various biological parameters and genotoxic markers, such as tumour cell count, mean survival of the animals, haematological indices, hepatocellular histology, immunohistochemical expression of liver metallothionein (MT) protein, sister-chromatid exchanges (SCEs), and DNA alterations. Treatment of the EAC-bearing mice with the ALE significantly (P < 0.001) reduced viable tumour cell count by 68.34% (228.7 x 10(6) +/- 0.53) when compared to EAC control mice (72.4 x 10(6) +/- 0.49), and restored body and organ weights almost to the normal values. ALE administration also increased (P < 0.001) mean survival of the hosts from 35 +/- 3.46 d in EAC control mice to 83 +/- 2.69 d in EAC + ALE-treated mice. Haematological indices also showed marked improvement with administration of ALE in EAC-bearing animals. There was a significant increase in RBC count (P < 0.001), hemoglobin percent (P < 0.001), and haematocrit value (P < 0.001) from 4.3 +/- 0.12, 6.4 +/- 0.93, and 17.63 +/- 0.72 respectively in EAC control mice to 7.1 +/- 0.13, 12.1 +/- 0.77, and 30.23 +/- 0.57 respectively in EAC + ALE-treated group, along with concurrent

The K+ and Cl− currents activated by hypotonic cell swelling were studied in Ehrlich ascites tumour cells using the whole-cell recording mode of the patch-clamp technique. Currents were measured in the absence of added intracellular Ca2+ and with strong buffering of Ca2+. K+ current activated by cell swelling was measured as outward current at the Cl− equilibrium potential (ECl) under quasi-physiological gradients. It could be abolished by replacing extracellular Na+ with K+, thereby cancelling the driving force. Replacement with other cations suggested a selectivity sequence of K+ > Rb+ > NH4≈ Na+≈ Li+; Cs+ appeared to be inhibitory. The current-voltage relationship of the volume-sensitive K+ current was well fitted with the Goldman-Hodgkin-Katz current equation between -130 and +20 mV with a permeability coefficient of around 10−6 cm s−1 with both physiological and high-K+ extracellular solutions. The class III antiarrhythmic drug clofilium blocked the volume-sensitive K+ current in a voltage-independent manner with an IC50 of 32 μM. Clofilium was also found to be a strong inhibitor of the regulatory volume decrease response of Ehrlich cells. Cell swelling-activated K+ currents of Ehrlich cells are voltage and calcium insensitive and are resistant to a range of K+ channel inhibitors. These characteristics are similar to those of the so-called background K+ channels. Noise analysis of whole-cell current was consistent with a unitary conductance of 5.5 pS for the single channels underlying the K+ current evoked by cell swelling, measured at 0 mV under a quasi-physiological K+ gradient.

1983-11-01

The preceding paper showed that IMP dehydrogenase [IMP:NAD+ oxidoreductase, EC 1.2.1.14] tended to form a precipitable complex(es) through ionic and hydrophobic interactions. On the basis of these observations, a method was developed for purification of IMP dehydrogenase from Yoshida sarcoma ascites cells. On SDS-polyacrylamide gel electrophoresis, the purified preparation (1.19 U/mg protein) appeared homogeneous and its minimum molecular weight was estimated to be 68K daltons. Amino acid analyses indicated a subunit molecular weight of 68,042. Molecular sieve chromatography in the presence of 10% (NH4)2SO4 showed that the molecular weight of the native enzyme was 127K daltons. These values indicate that the native enzyme is composed of two identical subunits. However, the purified enzyme gave 4 protein bands on polyacrylamide gel electrophoresis under non-denaturing conditions, and appeared as a single fraction in the vicinity of the void volume on Ultrogel AcA 34 column chromatography at low salt concentration, indicating that its molecular weight exceeded 200K daltons. These findings indicate that the enzyme tends to aggregate owing to its own physicochemical characteristics. The Km values for IMP and NAD were calculated to be 12 and 25 microM, respectively, and the Ki values for XMP, GMP, and AMP to be 109, 130, and 854 microM, respectively. The purified enzyme showed full activity in the presence of K+, and K+ could be partially replaced by Na+. PCMB inactivated the enzyme, but the activity was completely restored by the addition of DTT. Cl-IMP also inactivated the enzyme and IMP prevented this inactivation.(ABSTRACT TRUNCATED AT 250 WORDS)

Pharmacology of liposomal vincristine in mice bearing L1210 ascitic and B16/BL6 solid tumours.

Vincristine pharmacokinetic, tumour uptake and therapeutic characteristics were investigated here in order to elucidate the processes underlying the enhanced efficacy observed for vincristine entrapped in small (120 nm) distearoylphosphatidylcholine/cholesterol liposomes. Plasma vincristine levels after intravenous (i.v.) injection are elevated more than 100-fold in the liposomal formulation compared with free drug in tumour-bearing as well as non-tumour-bearing mice over 24 h. Biodistribution studies demonstrate that the extent and duration of tumour exposure to vincristine is dramatically improved when the drug is administered i.v. in liposomal form. Specifically, 72 h trapezoidal area under the curve values for liposomal vincristine in the murine L1210 ascitic and B16/BL6 solid tumours are 12.9- to 4.1-fold larger, respectively, than observed for free drug. Similar to previous results with the L1210 model, increased drug delivery to the B16 tumour results in significant inhibition of tumour growth, whereas no anti-tumour activity is observed with free vincristine. Comparisons of drug and liposomal lipid accumulation in tumour and muscle tissue indicate that the enhanced efficacy of liposomal vincristine is related predominantly to drug delivered by liposomes to the tumour site rather than drug released from liposomes in the circulation. Consequently, improvements in liposomal vincristine formulations must focus on factors that increase uptake of liposomes into tumour sites as well as enhance liposomal drug retention in the circulation.

In this study, we report evidence of the damage effects of sonodynamic therapy (SDT) on a novel intracellular target, cytoskeletal F-actin, that has great importance for cancer treatment. Ehrlich ascites carcinoma (EAC) cells suspended in PBS were exposed to ultrasound at 1.34 MHz for up to 60s in the presence and absence of protoporphyrin IX (PPIX). To evaluate the polymeric state and distribution of actin filaments (AF) we employed FITC-Phalloidin staining. The percentage of cells with intact AF was decreased with 10-80 microM PPIX after ultrasonic exposure, while only few cells with disturbed F-actin were observed with 80 microM PPIX alone. The fluorescence intensity of FITC-Phalloidin labeled cells was detected by flow cytometry. The morphological changes of EAC cells were observed by scanning electron microscope (SEM). The nuclei were stained with Hoechst 33258 to determine apoptosis. Cytoskeletal F-actin and cell morphological changes were dependent on the time after SDT. Some cells suffered deformations of plasma membrane as blebs that reacted positively to FITC-Phalloidin at 2h after SDT treatment. Many of the cells showed the typically apoptotic chromatin fragmentation. The alterations were more significant 4h later. Our results showed that cytoskeletal F-actin might represent an important target for the SDT treatment and the observed effect on F-actin and the subsequent bleb formation mainly due to apoptosis formation due to the treatment.

Reduced sister chromatid exchanges (SCE) frequency in response to cyclophosphamide (CP) was observed when Ehrlich ascites tumour (EAT) cells were exposed in vivo to 2 micrograms/g body weight of prostaglandin E2 (PGE2). 1 h before i.p. injection of 5-bromodeoxyuridine (BrdUrd) adsorbed to activated charcoal, EAT-bearing mice treated i.p. with CP appeared to have increased SCE rates and cell division delays. PGE2 had no effect on survival and in inhibiting tumour growth. CP had only a slight non-significant effect on survival and in inhibiting tumour growth. In mice treated with the combined CP (5 micrograms/g bd wt) plus PGE2 (2 micrograms/g bd wt) a significant enhancement (P < 0.01) of survival time was accompanied by inhibition of tumour growth (P < 0.01) in comparison with the untreated controls. These data imply that SCEs might result from errors in a repair process which might involve a PGE2 sensitive step.

In Brazil many health disorders are treated with the consumption of different varieties of tea. Shell extracts of pecan nut (Carya illinoinensis), which have significant amounts of phenolic compounds in their composition, are popularly taken as tea to prevent diverse pathologies. Phenolic compounds from pecan nut shell extract have been associated with diverse biological effects but the effect on tumor cells has not been reported yet. The aim of the current work was to evaluate the relationship between DNA fragmentation, cell cycle arrest and apoptosis induced by pecan nut shell extract and its antitumor activity. Cytotoxicity, proliferation, cell death and cell cycle were evaluated in MCF-7 cells by MTT, colony assay, differential coloring and flow cytometry assays, respectively. DNA damage effects were evaluated through intercalation into CT-DNA and plasmid DNA cleavage. Tumor growth inhibition, survival time increase, apoptosis and cell cycle arrest were assessed in Ehrlich ascites tumor in Balb/C mice. The cytotoxic effect of pecan nut shell extracts, the induction of cell death by apoptosis and also the cell cycle arrest in MCF-7 cells have been demonstrated. The survival time in mice with Ehrlich ascites tumor increased by 67%. DNA damage was observed in the CT-DNA, plasmid DNA and comet assays. The mechanism involved in the antitumor effect of pecan nut shell extracts may be related to the activation of key proteins involved in apoptosis cell death (Bcl-XL, Bax and p53) and on the cell cycle regulation (cyclin A, cyclin B and CDK2). These results were attributed to the phenolic profile of the extract, which presented compounds such as gallic, 4-hydroxybenzoic, chlorogenic, vanillic, caffeic and ellagic acid, and catechin, epicatechin, epigallocatechin and epicatechin gallate. The results indicated that pecan nut shell extracts are effective against tumor cells growth and may be considered as an alternative to the treatment of cancer. Copyright © 2017

(2'-5')(A)n synthetase and RNAase L (a latent endoribonuclease) are among the mediators of interferon action. The product of (2'-5')(A)n synthetase (i.e., (2'-5')(A)n) binds, and thereby activates RNAase L. Interferons induce in Ehrlich ascites tumor (EAT) cells two mRNAs (sizes 1.5 kb and 3.8 kb), which can be translated in Xenopus oocytes into (2'-5')(A)n synthetases of 20,000 to 30,000 daltons and 85,000 to 100,000 daltons, respectively. (2'-5')(A)n synthetases of corresponding sizes are induced by interferons in EAT cells. In the cell extract the bulk of the larger enzyme is in the cytoplasmic fraction, and the bulk of the smaller one in the nuclear fraction. The only known function of (2'-5')(A)n is the activation of RNAase L, and RNAase L can be selectively crosslinked to a (2'-5')(A)n derivative in a cytoplasmic extract from EAT cells. The same (2'-5')(A)n derivative can be crosslinked to several proteins in the nuclear extract of EAT cells, and some of these proteins are induced by interferon.

PROTEIN METABOLISM AND EXCHANGE AS INFLUENCED BY CONSTRICTION OF THE VENA CAVA

Constriction of inferior vena cava above the diaphragm is used to produce experimental ascites in the dog. This type of experimental ascites drains the body protein reserves, reduces the level of circulating plasma proteins, and in effect is an internal plasmapheresis. As the ascitic fluid is withdrawn and the proteins measured, we observe a production of ascitic protein (80–90 gm. per week) comparable to that removed by plasmapheresis (bleeding and replacement of red cells in saline). High protein diet tends to decrease the ascites but the protein content of the ascitic fluid may increase. Sodium chloride increases notably the volume of the ascites which accumulates and the total ascitic protein output increases. Sodium-free salt mixtures have a negative influence. High protein diet low in sodium salts gives minimal ascitic accumulation under these conditions. The question of circulation of the ascitic fluid is raised—how rapid is the absorption and the related accumulation? PMID:18858638

Regulation of S-adenosylmethionine decarboxylase by polyamines in Ehrlich ascites-carcinoma cells grown in culture

1. The mechanism of stimulation of S-adenosylmethionine decarboxylase (EC 4.1.1.50) activity by inhibitors of ornithine decarboxylase (EC 4.1.1.17), namely dl-α-difluoromethylornithine, 1,3-diaminopropane and 1,3-diaminopropan-2-ol, was studied in Ehrlich ascites-tumour cells grown in suspension cultures. 2. Difluoromethylornithine and diaminopropane, although decreasing the content of putrescine and spermidine, markedly stimulated adenosylmethionine decarboxylase activity after exposure of the cells to the drugs for 8h, whereas the effect of diaminopropanol only became apparent many hours later. In tumour cells exposed to any of the inhibitors, a close negative correlation existed between the activity of adenosylmethionine decarboxylase and the intracellular concentration of spermidine and/or spermidine plus spermine, suggesting that a depletion of higher polyamines triggered enhancement of adenosylmethionine decarboxylase activity. 3. The mechanism of difluoromethylornithine- and diaminopropane-induced stimulation of adenosylmethionine decarboxylase involved (a) a marked increase in the apparent half-life of the enzyme and (b) an induction of enhanced enzyme synthesis. Diaminopropanol seemed to act solely via an induction mechanism. 4. The increased adenosylmethionine decarboxylase activity elicited by difluoromethylornithine could be restored to control values by micromolar concentrations of exogenous spermidine and spermine in 4h and by putrescine in 22h. In addition to the natural polyamines, elevated adenosylmethionine decarboxylase activity could be repressed by 3,3′-iminodipropylamine, a close analogue of spermidine, but not by non-physiological diamines. 5. Addition of spermidine and actinomycin D to cultures treated with difluoromethylornithine produced a comparable decay of enhanced adenosylmethionine decarboxylase activity (with an apparent half-life of about 2.5h), whereas the effect of cycloheximide was much more rapid. The present results suggest

Ascites leaks (AL) in patients with end-stage liver disease (ESLD) are associated with significant morbidity and mortality regardless if they are medically or surgically managed. In a pilot study, 14 ESLD patients with AL underwent treatment with fibrin glue injection around the leak after failing conservative therapy. The end point of this study was the cessation of AL in the short term and the maintenance of a leak-free abdomen in the long term, allowing for medical optimization of the patients. Median age of the 10 men and 4 women was 50 (range 26-67) years. Underlying ESLDs were chronic hepatitis C (n=5), alcoholic LD (n=2), cryptogenic cirrhosis (n=2), and miscellaneous (n=5). There were six leaking incisions posthernia repair (three umbilical and three inguinal), two leaking/ruptured umbilical hernias, four leaking paracentesis sites, one leaking Jackson-Pratt (JP) drain canal, and one leaking laparoscopic trocar site. Average AL volume per day was 1000 (range 400-2000) mL. All leaks were immediately resolved with a 3-5 mL fibrin glue injection. Five recurred and required a second injection (four within 24 hours). Mental status improved in 7 patients (West Haven Criteria: grade II to I [n=6], grade III to I [n=1]). Median model of end-stage liver disease scores improved from 23 (range 8-33) to 20 (range 14-26). There were no infections, bleeds, or other injection-related complications. Average follow-up for these patients was 441.6 days (range 2-852). Five patients underwent liver transplant (LT) median 15 (range 4-270) days postinjection; 2 of them died. Another 3 patients died (2 from sepsis and 1 from metastatic cancer). Fibrin glue injection for the control of AL is a simple and safe bedside procedure that quickly controls AL, allowing for patient recovery in anticipation of further care.

Effect of anhydrosophoradiol-3-acetate of Calotropis gigantea (Linn.) flower as antitumoric agent against Ehrlich's ascites carcinoma in mice.

Over 60% of currently used anti-cancer agents are derived in one-way or another from natural sources, including plants, marine organisms and microorganisms. Calotropis gigantea (Linn.) (Family: Asclepiadaceae) is a perennial shrub and it is used as a traditional folk medicine for the treatment of various health complications. But there is no report on isolation of anticancerous chemicals from the flower of Calotropis gigantea. The objective of the present study is to explore the antitumor effect of anhydrosophoradiol-3-acetate (A3A), isolated from the flower of Calotropis gigantea (Linn.) against Ehrlich's ascites carcinoma (EAC) in Swiss albino mice. Antitumoric effect of A3A was assessed by evaluating viable tumor cell count, survival time, body weight gain due to tumor burden, hematological and biochemical (glucose, cholesterol, triglyceride, blood urea, SALP, SGPT and SGOT) parameters of EAC bearing host at doses of 10 and 20 mg/kg body weight. Treatment with A3A decreased the viable tumor cells and body weight gain thereby increasing the life span of EAC bearing mice. A3A also brought back the altered hematological (Hb, total RBC and total WBC) and biochemical parameters more or less to normal level. Results of this study conclude that in vivo the A3A was effective in inhibiting the growth of EAC with improving in cancer induced complications.

From a wild type strain of Ehrlich ascites tumor (EATWT) sublines resistant to daunorubicin (EATDNM), etoposide (EATETO), and cisplatinum (EATCIS) have been developed in vivo. Increase in survival and cure rate caused by adriamycin (doxorubicin) have been determined in female NMRI mice which were inoculated i.p. with EAT cells. Adriamycin concentrations causing 50% inhibition of 3H-thymidine (ICT) and 3H-uridine incorporation (ICU) and intracellular adriamycin steady-state concentrations (SSC) were measured in vitro. Adriamycin resistance increased and SSC decreased in the following sequence: EATWT - EATCIS - EATDNM - EATETO. When ICT and ICU were corrected for intracellular adriamycin concentrations in consideration of the different SSC (ICTc, ICUc), ICTc and ICUc still varied up to the 3.2 fold in EATCIS, EATDNM and EATETO in comparison to EATWT. Thus, in addition to different SSC other factors must be responsible for adriamycin resistance. Therefore, enzymes which may play a role in the cytotoxicity related to adriamycin metabolism (NADPH-cytochrome P-450 reductase, NADPH-glutathione reductase, NADP-glucose-6-phosphate dehydrogenase, NADP-isocitrate dehydrogenase) were measured. In contrast to the other parameters determined, NADPH-glutathione reductase was significantly (p less than 0.01) increased up to the 3.2 fold parallel to adriamycin resistance as determined by increase in life span, cure rate, ICTc, and ICUc, respectively. It is concluded that high activities of NADPH-glutathione reductase may contribute to an increase in adriamycin resistance of malignant tumors.

Further studies of ascitic fluid production and related factors in dogs with constriction of the vena cava above the diaphragm are reported. Whole dog plasma given intravenously to such animals produces a rise in circulating plasma protein to normal levels, but increases the output of ascitic fluid with a loss of protein via the ascites equivalent to 72, 76, and 65 per cent respectively, of the injected protein. Forced ingestion of water in excess of the test animal's normal needs and desires produces no significant changes in the circulating plasma protein level or in ascitic fluid production. Amino acid growth mixtures given intravenously in distilled water cause weight loss, elevation of circulating plasma proteins, a slightly negative nitrogen balance, but no ascitic fluid production. Amino acid growth mixtures given intravenously in normal saline cause depression of the circulating plasma proteins, negative nitrogen balance, and significant ascitic fluid production. Ascitic fluid given intravenously to the test animals causes a marked depression of circulating plasma proteins, a marked increase in ascitic fluid production containing the equivalent of 116 and 98 per cent of the injected protein, and a negative nitrogen balance. Ascitic fluid given orally produces a marked depression of circulating plasma proteins, and a marked increase in ascitic fluid secretion, containing the equivalent of 66, 66, and 54 per cent respectively, of the ingested protein. Sodium chloride is a dominant factor in some of these experiments where abundant ascites production is recorded. Protein levels and intake are important, but take second place to sodium. Ascitic fluids show electrophoretic patterns which are almost identical to the plasma patterns. The A/G ratios are often equal in ascitic fluid and plasma, sometimes even lower in the ascitic fluid. This emphasizes the ease with which globulins pass cell or other membrane barriers in these experiments. PMID:18143588

Liver cirrhosis is associated with functional abnormalities of the cardiovascular system with co-existing electrocardiographic (ECG) abnormalities. The aim was to analyze ECG changes in patients with cirrhosis, to evaluate whether alcoholic etiology of cirrhosis and ascites has an impact on ECG changes. The study involved 81 patients with previously untreated alcoholic cirrhosis (64 patients with ascites, classes B and C according to the Child-Pugh classification; and 17 without ascites, categorized as class A); 41 patients with previously untreated cirrhosis due to chronic hepatitis C (HCV--30 patients with ascites, classes B and C; and 11 without ascites, class A); 42 with alcoholic steatohepatitis and 46 with alcoholic steatosis. The control group consisted of 32 healthy volunteers. Twelve-lead ECG recordings were performed and selected parameters were measured. Significantly longer QT and QTc intervals and lower QRS voltage were found in patients with alcoholic and HCV cirrhosis compared to the controls. Significantly lower QRS voltage was found in subjects with ascites than in those without ascites. Removal of ascites significantly increased QRS voltage. In cirrhosis, irrespective of etiology, ECG changes involved prolonged QT and QTc intervals and reduced QRS voltage. Prolonged QT and QTc intervals were not related to the severity of cirrhosis or to the presence of ascites. However, low QRS voltage was associated with the presence of ascites. Removal of ascites reverses low QRS voltage.

It is estimated that venoms of marine cone snails (genus Conus) contain more than 100,000 different small peptides with a wide range of pharmacological and biological actions. Some of these peptides were developed into potential therapeutic agents and as molecular tools to understand biological functions of nervous and cardiovascular systems. In this study we examined the cytotoxic and anticancer properties of the marine vermivorous cone snail Conus vexillum (collected from Hurgada and Sharm El-Shaikh, Red Sea, Egypt) and suggest the possible mechanisms involved. The in vitro cytotoxic effects of Conus venom were assessed against Ehrlich's ascites carcinoma (EAC) cells. Conus venom treatment resulted in concentration-dependent cytotoxicity as indicated by a lactate dehydrogenase leakage assay. Apoptotic effects were measured in vivo by measuring levels of reactive oxygen species and oxidative defense agents in albino mice injected with EAC cells. Conus venom (1.25 mg/kg) induced a significant increase (p < 0.05) in several oxidative stress biomarkers (lipid peroxidation, protein carbonyl content and reactive nitrogen intermediates) of EAC cells after 3, 6, 9 and 12 hours of venom injection. Conus venom significantly reduced (p < 0.05) the activities of oxidative defense enzymes (catalase and superoxide dismutase) as well as the total antioxidant capacity of EAC cells, as evidenced by lowered levels of reduced glutathione. These results demonstrate the cytotoxic potential of C. vexillum venom by inducing oxidative stress mediated mechanisms in tumor cells and suggest that the venom contains novel molecules with potential anticancer activity.

Fluctuation analysis experiments were performed to assess whether selection or induction determines expression of P-glycoprotein and resistance in the murine Ehrlich ascites tumour cell line (EHR2) after exposure to daunorubicin. Thirteen expanded populations of EHR2 cells were exposed to daunorubicin 7.5 x 10(-9) M or 10(-8) M for 2 weeks. Surviving clones were scored and propagated. Only clones exposed to daunorubicin 7.5 x 10(-9) M could be expanded for investigation. Drug resistance was assessed by the tetrazolium dye (MTT) cytotoxicity assay. Western blot was used for determination of P-glycoprotein. Compared with EHR2, the variant cells were 2.5- to 5.2-fold resistant to daunorubicin (mean 3.6-fold). P-glycoprotein was significantly increased in 11 of 25 clones (44%). Analysis of variance supported the hypothesis that spontaneous mutations conferred drug resistance in EHR2 cells exposed to daunorubicin 7.5 x 10(-9) M. At this level (5 log cell killing) of drug exposure, the mutation rate was estimated at 4.1 x 10(-6) per cell generation. In contrast, induction seemed to determine resistance in EHR2 cells in vitro exposed to daunorubicin 10(-8) M. The revertant EHR2/0.8/R was treated in vivo with daunorubicin for 24 h. After treatment, P-glycoprotein increased in EHR2/0.8/R (sevenfold) and the cell line developed resistance to daunorubicin (12-fold), suggesting that in EHR2/0.8/R the mdr1 gene was activated by induction. In conclusion, our study demonstrates that P-glycoprotein expression and daunorubicin resistance are primarily acquired by selection of spontaneously arising mutants. However, under certain conditions the mdr1 gene may be activated by induction. PMID:9820176

Purification of immunoglobulin M (IgM) antibodies could be challenging, and is often characterized by the optimization of the purification protocol to best suit the particular features of the molecule. Here, two different schemes were compared to purify, from ascites, the 1E4 IgM monoclonal antibody (mAb) previously raised against the stage of redia of the trematode Fasciola hepatica. This immunoglobulin is used as capture antibody in an immunoenzymatic assay to detect parasite ongoing infection in its intermediate hosts. The first purification protocol of the 1E4 mAb involved two chromatographic steps: an affinity chromatography on a Concanavalin A matrix followed by size exclusion chromatography. An immunoaffinity chromatography was selected as the second protocol for one-step purification of the antibody using the crude extract of adult parasites coupled to a commercial matrix. Immunoreactivity of the fractions during purification schemes was assessed by indirect immunoenzymatic assays against the crude extract of F. hepatica rediae, while purity was estimated by protein electrophoresis. Losses on the recovery of the antibody isolated by the first purification protocol occurred due to protein precipitation during the concentration of the sample and to low resolution of the size exclusion molecular chromatography step regarding this particular immunoglobulin. The immunoaffinity chromatography using F. hepatica antigens as ligands proved to be the most suitable protocol yielding a pure and immunoreactive antibody. The purification protocols used are discussed regarding efficiency and difficulties.

The activation of the p53 pathway through the inhibition of MDM2 has been proposed as a novel therapeutic strategy against tumours. A series of cis-imidazoline analogues, termed nutlins, were reported to displace the recombinant p53 protein from its complex with MDM2 by binding to MDM2 in the p53 pocket, and exhibited an antitumour activity both in vitro and in vivo. Thus, the purpose of this study was to evaluate the antitumour properties of LQFM030 (2), a nutlin analogue created by employing the strategy of molecular simplification. LQFM030 (2) cytotoxicity was evaluated in Ehrlich ascites tumour (EAT) cells, p53 wild type, by the trypan blue exclusion test, and the mechanisms involved in EAT cell death were investigated by light and fluorescence microscopy, flow cytometry, real-time PCR and Western blotting. Our results demonstrate that LQFM030 has dose-dependent antiproliferative activity and cytotoxic activity on EAT cells, induces the accumulation of p53 protein and promotes cell cycle arrest and apoptosis. p53 gene transcription was unaffected by LQFM030 (2); however, MDM2 mRNA increased and MDM2 protein decreased. These results suggest that the small-molecule p53 activator LQFM030 (2) has the potential for further development as a novel cancer therapeutic agent. © 2016 Royal Pharmaceutical Society.

The initial rate of incorporation of 14C or 3H-labeled choline into Ehrlich-Lettre ascites cells of the glycogen-free strain seven days after inoculation was investigated in vitro. 1. At choline concentrations in the medium between 6 to 30 muM and 100 to 500 muM the choline uptake by the cells followed Michaelis-Menton Kinetics with V values between 31 to 100 and 59 to 500 pmol per minute at a given cell density, and average Q10-values of 2.1 at the high and of 2.4 at the low choline molarity. The K-m-values increased from 27 muM to 58.8 muM at low and from 0.11 mM to 0.22 mM at high choline concentrations over a temperature range between 15 degrees C and 37 degrees C. Arrhenius plot of the V values gave two lines, one with a transition temperature at 25 degrees C at low and one straight line at high choline concentrations, from which the energy of activation for choline uptake was determined to be 16 kcal/mol. 2. It is assumed that two systems exist for the choline uptake by the ascites cells. One, operative at low substrate concentrations, which is saturable and probably is to be classified as a carrier-mediated facilitated diffusion process, can be strongly inhibited by deoxyglucose or 2,4-dinitrophenol and also by substrate analogues such as chlorocholine or benzoylcholine. Ouabain affects this system to a lesser extent. The other system functioning at high choline concentrations may be a simple diffusion process, which is little inhibited by substrate analogues, ouabain and deoxyglucose; however, it is also inhibited by 2,4-dinitrophenol and p-chloromercuribenzoate. 3. Choline incorporation into the acid-insoluble material (lecithin) gave linear Michaelis-Menton kinetics at the low and the high substrate concentration respectively. K-m-values decreased with an increase in temperature at low and increased with rising temperature at high substrate concentrations thus reflecting a close relationship between choline uptake and its metabolism.

The multidrug resistance (MDR) phenotype is presumed to be mostly dependent on changes in the resistant cell plasma membrane, notably the emergence of a 170 kDa glycoprotein called P-glycoprotein, which facilitate increased drug efflux. We have previously demonstrated that ATP-enhanced binding of vincristine (VCR) to plasma membrane vesicles is much greater in MDR than in wild type cells. The present study has shown that VCR binding to MDR Ehrlich ascites tumour cell plasma membrane vesicles is inhibited 50% most efficiently by quinidine (0.5 microM) followed by verapamil (4.1 microM) and trifluoperazine (23.2 microM). This is the reverse order of the effect on whole cells where a ranking of efficiency in terms of enhancement of VCR accumulation, inhibition of VCR efflux, DNA perturbation and modulation of resistance in a clonogenic assay, was trifluoperazine greater than or equal to verapamil much greater than quinidine. The detergent Tween 80 inhibited VCR binding to plasma membrane vesicles at 0.001% v/v which agreed with the level which modulated resistance and increased VCR accumulation in whole cells. No effect was observed on daunorubicin binding to MDR plasma membrane vesicles after incubation with either Tween 80 (up to 0.1% v/v) or verapamil (up to 25 microM). We conclude that the effect of a modulating drug in reversing resistance to VCR correlates with its ability to raise intracellular VCR levels but not with its capability to inhibit VCR binding to the plasma membrane. Thus, enhancement of VCR accumulation in MDR cells is hardly solely due to competition for a drug binding site on P-glycoprotein. Furthermore, the lack of a demonstrable effect on daunorubicin binding to the plasma membrane by modulators points to transport mechanisms which do not utilise specific drug binding to the plasma membrane.

Ascites syndrome (AS), also known as pulmonary artery hypertension, remains a challenging disease that severely affects both humans and broiler chickens. Pulmonary artery remodeling presents a key step in the development of AS. In this study, we obtained pulmonary artery tissues from broilers with and without AS to perform miRNA sequencing analysis, miRNA-mRNA association analysis and pathological examinations. 29 significantly differentially expressed miRNAs were found both in known and novel miRNAs with 18 up-regulated and 11 down-regulated miRNAs. Their predicted potential targets were involved in a wide range of functional clusters as indicated via GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) analyses. The upregulation of miR-155, miR-23b-3p, miR-146b-5p and miR-146b-3p were found closely associated with the pathogenesis of pulmonary artery remodeling in AS progression. The association analysis for the miRNAs-mRNAs showed that these 29 significantly differentially expressed miRNAs regulate 162 differentially expressed target genes. Among them, 20 miRNAs correlated with 18 predicted target genes that appear to be involved in pulmonary artery remodeling, mainly in three broad physiological processes: the hypoxia sensing response (HIF1a, NHE1, STAT5 and STAT3), endothelial permeability dysfunction (CD44, TRAF2, CDK2AP1, LZTFL1, JAZF1, PEBP1, LRP1B, RPS14 and THBS2) and inflammation (MEOX2, STAT5, STAT3, IRF8, MAP3K8, IL-1BETA and TNFRSF1B). Pathological pulmonary artery remodeling in the AS broilers was consistently observed in the present study. Taken together, the current analysis further illuminates the molecular mechanism of pulmonary artery remodeling underlying AS progression. PMID:27791988

Glucose uptake study plays a major role in diabetes research. Impaired glucose uptake has been implicated in the development of hyperglycemia during diabetes. Banana plant is known for its anti-diabetic properties and our earlier report revealed that banana flower and pseudostem of Musa sp. cv. elakki bale is beneficial during diabetes in rat models. The present study was designed to evaluate the potential effect of banana flower and pseudostem extracts on glucose uptake in Ehrlich ascites tumor (EAT) cells using 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-D-glucose (2-NBDG), a fluorescent analogue of 2-deoxyglucose. Methanol and aqueous extracts of banana flower and pseudostem were more potent in promoting glucose uptake in EAT cells, in comparison to acetone and ethanol extracts. At 20 µg dosage, highest net glucose uptake was observed in aqueous extracts of banana flower (18.17 ± 0.43 nmol L⁻¹) and pseudostem (19.69 ± 0.41 nmol L⁻¹). Total polyphenol content was higher in methanol (9.031 ± 0.036 g kg⁻¹) and aqueous (6.862 ± 0.024 g kg⁻¹) extracts of banana flower compared to pseudostem, which were 0.442 ± 0.006 and 0.811 ± 0.011 g kg⁻¹, respectively. Banana flower and pseudostem extracts are able to promote glucose uptake into the cells, presumably through glucose transporters 1 and 3, which could be beneficial in diabetes. Glucose uptake is likely promoted by phenolic acids besides other bioactives. It can be hypothesized that consumption of nutraceutical-rich extract of banana flower and pseudostem could replace some amount of insulin being taken for diabetes.

We studied the effects of caffeine alone or in combination with homo-aza-steroidal ester of p-bis(2-chloroethyl)aminophenylacetic acid (ASE, NSC 290205) on the frequency of SCEs and lymphocyte proliferation kinetics. Caffeine was found to act synergistically with ASE on the induction of SCEs when the two components were administered in combination. Caffeine was also found to act synergistically with ASE in inducing cell-division delays. Enhanced cytogenetic damage by ASE was observed when Ehrlich ascites tumour cells (EAT cells) were exposed in vivo to caffeine. ASE alone or in combination with caffeine caused a dose-dependent increase in SCE rates and cell-division delays. SCEs were demonstrated in EAT-bearing mice, by the i.p. injection of BrdUrd adsorbed onto activated charcoal, 1 h after the i.p. injection of ASE and/or caffeine.

Cirrhosis is a frequent and severe disease, complicated by renal sodium retention leading to ascites and oedema. A better understanding of the complex mechanisms responsible for renal sodium handling could improve clinical management of sodium retention. Our aim was to determine the importance of the amiloride-sensitive epithelial sodium channel (ENaC) in collecting ducts in compensate and decompensate cirrhosis. Bile duct ligation was performed in control mice (CTL) and collecting duct-specific αENaC knockout (KO) mice, and ascites development, aldosterone plasma concentration, urinary sodium/potassium ratio and sodium transporter expression were compared. Disruption of ENaC in collecting ducts (CDs) did not alter ascites development, urinary sodium/potassium ratio, plasma aldosterone concentrations or Na,K-ATPase abundance in CCDs. Total αENaC abundance in whole kidney increased in cirrhotic mice of both genotypes and cleaved forms of α and γ ENaC increased only in ascitic mice of both genotypes. The sodium chloride cotransporter (NCC) abundance was lower in non-ascitic KO, compared to non-ascitic CTL, and increased when ascites appeared. In ascitic mice, the lack of αENaC in CDs induced an upregulation of total ENaC and NCC and correlated with the cleavage of ENaC subunits. This revealed compensatory mechanisms which could also take place when treating the patients with diuretics. These compensatory mechanisms should be considered for future development of therapeutic strategies.

Donkey milk and donkey milk kefir exhibit antiproliferative, antimutagenic and antibacterial effects. We investigated the effects of donkey milk and donkey milk kefir on oxidative stress, apoptosis and proliferation in Ehrlich ascites carcinoma (EAC) in mice. Thirty-four adult male Swiss albino mice were divided into four groups as follows: group 1, administered 0.5 ml water; group 2, administered 0.5 ml water + EAC cells; group 3, administered 0.5 ml donkey milk + EAC cells; group 4, administered 0.5 ml donkey milk kefir + EAC cells. We introduced 2.5 x 10 6 EAC cells into each animal by subcutaneous injection. Tap water, donkey milk and donkey milk kefir were administered by gavage for 10 days. Animals were sacrificed on day 11. After measuring the short and long diameters of the tumors, tissues were processed for histology. To determine oxidative stress, cell death and proliferation iNOS and eNOS, active caspase-3 and proliferating cell nuclear antigen were assessed using immunohistochemistry. A TUNEL assay also was used to detect apoptosis. Tumor volume decreased in the donkey milk kefir group compared to the control and donkey milk groups. Tumor volume increased in the donkey milk group compared to the control group. Proliferating cell nuclear antigen levels were higher in the donkey milk kefir group compared to the control and donkey milk groups. The number of apoptotic cells was less in the donkey milk group, compared to the control, whereas it was highest in the donkey milk kefir group. Donkey milk administration increased eNOS levels and decreased iNOS levels, compared to the control group. In the donkey milk kefir group, iNOS levels were significantly lower than those of the control and donkey milk groups, while eNOS levels were similar to the control group. Donkey milk kefir induced apoptosis, suppressed proliferation and decreased co-expression of iNOS and eNOS. Donkey milk promoted development of the tumors. Therefore, donkey milk kefir appears to

To promote the specific targeting and elimination of CD44-positive cancer cells, berberine chloride (BRB)-encapsulated hyaluronic acid-grafted poly(lactic-co-glycolic acid) copolymer (BRB-d(HA)-g-PLGA) nanoparticles (NPs) were prepared. The targeted action of these NPs was compared to non-targeted BRB-loaded PLGA NPs and bulk BRB. The in vitro studies demonstrated faster release of BRB and increased cytotoxicity of BRB-d(HA)-g-PLGA NPs in Hela and MCF-7 cells in comparison to BRB-PLGA NPs and bulk BRB. The uptake of BRB-d(HA)-g-PLGA NPs was increased in case of MCF-7 cells as compared to HeLa cells owing to the higher expression of CD44 receptors on MCF-7 cells. The CD44 receptor-mediated uptake of these NPs was confirmed through competitive inhibition experiments. The in vitro results were further validated in vivo in Ehrlich Ascites Carcinoma (EAC)-bearing mice. EAC-bearing mice were injected intravenously with these NPs and the results obtained were compared with that of BRB-PLGA NPs and bulk BRB. BRB-d(HA)-g-PLGA NPs were found to significantly enhance apoptosis, sub-G1 content, life span, mean survival time, and ROS levels in EAC cells with subsequent decrease in mitochondrial membrane potential and tumor burden ion tumor-bearing mice. Taking into account the findings of in vitro and in vivo studies, the enhanced and targeted anti-tumor activity of HA-grafted PLGA copolymer-encapsulated NPs of BRB cannot be negated. Therefore, HA-grafted nanoparticle-based delivery of BRB may offer a promising and improved alternative for anti-tumor therapy.

The clinical success of the applicability of tea polyphenols awaits efficient systemic delivery and bioavailability. Herein, following the concept of nanochemoprevention, which uses nanotechnology for enhancing the efficacy of chemotherapeutic drugs, we employed tea polyphenols, namely theaflavin (TF) and epigallocatechin-3-gallate (EGCG) encapsulated in a biodegradable nanoparticulate formulation based on poly(lactide-co-glycolide) (PLGA) with approximately 26% and 18% encapsulation efficiency, respectively. It was observed that TF/EGCG encapsulated PLGA nanoparticles (NPs) offered an up to ~7-fold dose advantage when compared with bulk TF/EGCG in terms of exerting its antiproliferative effects and also enhanced the anticancer potential of cisplatin (CDDP) in A549 (lung carcinoma), HeLa (cervical carcinoma), and THP-1 (acute monocytic leukemia) cells. Cell cycle analysis revealed that TF/EGCG-NPs were more efficient than bulk TF/EGCG in sensitizing A549 cells to CDDP-induced apoptosis, with a dose advantage of up to 20-fold. Further, TF/EGCG-NPs, alone or in combination with CDDP, were more effective in inhibiting NF-κB activation and in suppressing the expression of cyclin D1, matrix metalloproteinase-9, and vascular endothelial growth factor, involved in cell proliferation, metastasis, and angiogenesis, respectively. EGCG and TF-NPs were also found to be more effective than bulk TF/EGCG in inducing the cleavage of caspase-3 and caspase-9 and Bax/Bcl2 ratio in favor of apoptosis. Further, in vivo evaluation of these NPs in combination with CDDP showed an increase in life span (P<0.05) in mice bearing Ehrlich’s ascites carcinoma cells, with apparent regression of tumor volume in comparison with mice treated with bulk doses with CDDP. These results indicate that EGCG and TF-NPs have superior cancer chemosensitization activity when compared with bulk TF/EGCG. PMID:26586942

Umbilical hernia in patients with liver cirrhosis: A surgical challenge

Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment. PMID:27462389

Ventriculoperitoneal (VP) shunt insertion is the most common cerebrospinal fluid (CSF) diversionary procedure used for the treatment of chronic hydrocephalus. Sterile CSF ascites is a rare complication of VP shunt insertion. This can arise from either an overproduction of CSF or inadequate filtration of CSF at the level of the peritoneum. By either mechanism, the development of CSF ascites requires an intact VP shunt. The authors discuss two paediatric cases diagnosed with suprasellar pilocytic astrocytomas treated with platinum-based chemotherapy, who subsequently developed sterile CSF ascites. We review the literature with regard to CSF malabsorption and discuss it as a contributing factor to shunt malfunction. CSF malabsorption with resultant ascites is a rare complication of VP shunting with many etiologies. Two common predisposing factors included the use of platinum-based chemotherapeutic agents, as well as the specific neuropathology. Further analysis of these two entities is needed in order to elucidate their role in contributing to the development of CSF ascites in this patient cohort.

AIM: To evaluate the feasibility of using an automated spring-loaded needle device for endoscopic ultrasound (EUS)-guided abdominal paracentesis (EUS-P) to see if this would make it easier to puncture the mobile and lax gastric wall for EUS-P. METHODS: The EUS database and electronic medical records at Fukushima Medical University Hospital were searched from January 2001 to April 2011. Patients with a history of cancer and who underwent EUS-P using an automated spring-loaded needle device with a 22-gauge puncture needle were included. The needle was passed through the instrument channel and advanced through the gastrointestinal wall under EUS guidance into the echo-free space in the abdominal cavity and ascitic fluid was collected. The confirmed diagnosis of malignant ascites included positive cytology and results from careful clinical observation for at least 6 mo in patients with negative cytology. The technical success rate, cytology results and complications were evaluated. RESULTS: We found 11 patients who underwent EUS-P with an automated spring-loaded needle device. In 4 cases, ascites was revealed only with EUS but not in other imaging modalities. EUS-P was done in 7 other cases because there was minimal ascitic fluid and no safe window for percutaneous abdominal aspiration. Ascitic fluid was obtained in all cases by EUS-P. The average amount aspirated was 14.1 mL (range 0.5-38 mL) and that was sent for cytological exam. The etiology of ascitic fluid was benign in 5 patients and malignant in 6. In all cases, ascitic fluid was obtained with the first needle pass. No procedure-related adverse effects occurred. CONCLUSION: EUS-P with an automated spring-loaded needle device is a feasible and safe method for ascites evaluation. PMID:24567793

N-ω-chloroacetyl-L-ornithine (NCAO) is an ornithine decarboxylase (ODC) inhibitor that is known to exert cytotoxic and antiproliferative effects on three neoplastic human cancer cell lines (HeLa, MCF-7, and HepG2). Here, we show that NCAO has antiproliferative activity in 13 cancer cell lines, of diverse tissue origin from human and mice, and in a mouse cancer model in vivo. All cell lines were sensitive to NCAO after 72 h of treatment (the EC50 ranged from 1 to 50.6 µmol/l). The Ca Ski cell line was the most sensitive (EC50=1.18±0.07 µmol/l) and MDA-MB-231 was the least sensitive (EC50=50.6±0.3 µmol/l). This ODC inhibitor showed selectivity for cancer cells, exerting almost no cytotoxic effect on the normal Vero cell line (EC50>1000 µmol/l). NCAO induced apoptosis and inhibited tumor cell migration in vitro. Furthermore, in vivo, this compound (at 50 and 100 mg/kg, daily intraperitoneal injection for 7 days) exerted potent antitumor activity against both solid and ascitic tumors in a mouse model using the myeloma (Ag8) cell line. At these same two doses, the toxicological evaluation showed that NCAO has no obvious systemic toxicity. The current results suggest that the antitumor activity is exerted by apoptosis related not only to a local but also a systemic cytotoxic effect exerted by NCAO on tumor cells. The applications for NCAO as an antitumor agent may be extensive; however, further studies are needed to ascertain the antitumor activity on other types of tumor in vivo and to determine the precise molecular mechanism of its activity.

As liver cirrhosis is a dynamic condition, it is possible to improve survival in decompensated cirrhosis. Hence, we planned a prospective study to determine the natural history of cirrhosis after first decompensation. We enrolled all patients of liver cirrhosis who presented with first episode of decompensation defined by the presence of ascites, either overt or detected by Ultrasonography (UD), Gastroesophageal Variceal Bleeding (GEVB), and Hepatic Encephalopathy (HE). All patients were followed up to death/liver transplant or at least for the period of 1 year. Multivariable Cox proportional hazards regression was used to analyze the risk of failure (death or Orthotopic Liver Transplantation (OLT)). In total of 110 cirrhotic patients (93 males, mean age 50 ± 11 years), the most frequent etiology was alcohol (48%), followed by nonalcoholic steatohepatitis/cryptogenic (26%), hepatitis B (10%), autoimmune hepatitis (7%), and hepatitis C (6%). The distribution of CTP classes was: 4%, 56%, and 41% in class A, B, and C, respectively. Ascites was the most common decompensation found in 88 patients (80%) followed by HE (14%) and GEVB (6%). At 1-year follow up, transplant free survival was 78%, 2 underwent OLT, 4 developed hepatocellular carcinoma, and 24 died. Cumulative incidence of failure (death or OLT) by type of decompensation after 1 year was: 22% overt ascites, 50% GEVB, 28% UD ascites, 20% HE, and 33% ascites and GEVB concomitant. Patients with UD ascites do not have a negligible mortality rate as compared to overt ascites. Patients with cirrhosis after first decompensation have better transplant free survival with treatment of etiology and complications than previously mentioned in literature.

We report a rare complication of incarceration of an umbilical hernia after Denver peritoneovenous shunt placement. A 50-year-old man presented with refractory ascites from liver cirrhosis. He also had an umbilical hernia. Because the ascites became uncontrollable, Denver peritoneovenous shunting was performed. The operation was successful and the ascites decreased. Ten days later, however, incarceration of the umbilical hernia occurred. A surgical repair was performed, but he died 2 days later. The cause of death was considered to be sepsis.

Preclinical studies in ovarian cancer have demonstrated upregulation of the Wnt/β-catenin pathway promoting tumor proliferation and chemoresistance. Our objective was to evaluate the effect of the Wnt/β-catenin pathway inhibitor, WNT974, in primary ovarian cancer ascites cells. Ascites cells from patients with papillary serous ovarian cancer were isolated and treated with 1 μM WNT974±100 μM carboplatin. Viability was evaluated with the ATPlite assay. The IC50 was calculated using a dose-response analysis. Immunohistochemistry (IHC) was performed on ascites cells and tumor. Expression of R-spondin 2 (RSPO2), RSPO3, PORCN, WLS, AXIN2, and three previously characterized RSPO fusion transcripts were assessed using Taqman assays. Sixty ascites samples were analyzed for response to WNT974. The ascites samples that showed a decrease in ATP concentration after treatment demonstrated no difference from the untreated cells in percent viability with trypan blue staining. Flow cytometry demonstrated fewer cells in the G2 phase and more in the G1 and S phases after treatment with WNT974. Combination therapy with WNT974 and carboplatin resulted in a higher percentage of samples that showed ≥30% reduction in ATP concentration than either single drug treatment. IHC analysis of Wnt pathway proteins suggests cell cycle arrest rather than cytotoxicity after WNT974 treatment. QPCR indicated that RSPO fusions are not prevalent in ovarian cancer tissues or ascites. However, higher PORCN expression correlated to sensitivity to WNT974 (P=0.0073). In conclusion, WNT974 produces cytostatic effects in patient ascites cells with primary ovarian cancer through inhibition of the Wnt/β-catenin pathway. The combination of WNT974 and carboplatin induces cytotoxicity plus cell cycle arrest in a higher percentage of ascites samples than with single drug treatment. RSPO fusions do not contribute to WNT974 sensitivity; however, higher PORCN expression indicates increased WNT974 sensitivity.

In recent ten years one of the major problems of modern radiobiology is the study of radiation protective mechanisms with the help of different substances as well as activation of internal resources of the organism. Internal resources mean such phenomena as hormesis and adaptive response which represent cell or body reaction on low doses of inducing factors and predetermine their further high dose effect resistance. At present special interest is attracted by studies of biological effects of low-dose-rate high-LET radiation because of searching for new types of radiation for more effective cancer therapy and searching for new methods of radiation protection. Since natural biologically active substances have low toxicity and are capable of affecting physiological processes taking place in human’s organism and increasing organism’s natural defense system, the interest to protective means of vegetal origin and search of special food supplements intensifies every year. The purpose of this study is to investigate the combined influence of food supplement, low dose rate high-LET radiation simulating high-altitude flight conditions and X-ray radiations on radiosensitivity, induction of radiation adaptive response (RAR) and growth of Ehrlich ascite carcinoma as well. Experiments were performed with males of SHK mice at the age of two months. The animals were being irradiated with low-dose-rate high-LET radiation with the dose of 11,6 cGy (0,5 cGy/day) behind the concrete shield of the 70 GeV protons accelerator (Protvino). The X-ray irradiation was carried out on the RTH device with a voltage of 200 kV (1 Gy/min; Pushchino). The diet composition included products containing big amount of biologically active substances, such as: soybeam meat, buckwheat, lettuce leaves and drug of cod-liver oil. Four groups of mice were fed with selected products mentioned above during the whole irradiation period of 22 days. The control groups received the same food without irradiation

Hepatorenal syndrome (HRS) is a functional renal failure that occurs late during cirrhosis. The prognosis is extremely poor with a mean survival of 1.7 wks from the time of diagnosis. The aim of the present study was to examine the effects of albumin and furosemide administration tailored to central venous pressure (CVP) on renal function and clinical outcome. We treated 20 consecutive patients with HRS. Albumin was given to increase and/or maintain CVP above 3 cm H(2)O. If diuresis remained below 50 mL/h despite effective volume expansion, furosemide was administrated. Patients were considered responders and treatment was discontinued when creatinine clearance rose above 40 mL/min or serum creatinine fell under 132 mumol/L. The need for albumin varied from patient to patient (extremes 40-600 g) and in the same patient from day to day. All but one needed furosemide. Eleven patients (55%) responded to treatment. In this population, diuresis, serum creatinine, and creatinine clearance were all significantly improved. Creatinine clearance at baseline was predictive of treatment efficacy. Survival increased in these patients compared to nonresponders defined as patients with no improvement in renal function (259 days +/- 113 compared to 14 days +/- 3, p < 0.0005). Response to treatment and the type of HRS were the only variables with an independent prognostic value. This study shows that HRS as defined by the International Ascites Club can be treated by albumin administration alone or with furosemide given according to the patient's specific need using CVP.

Even though hepatic veno-occlusive disease (VOD) is a potentially fatal complication of hematopoietic cell transplantation (HCT), there is paucity of research on the management of associated multiorgan dysfunction. To help provide standardized care for the management of these patients, the HCT Subgroup of the Pediatric Acute Lung Injury and Sepsis Investigators and the Supportive Care Committee of the Pediatric Blood and Marrow Transplant Consortium, collaborated to develop evidence-based consensus guidelines. After conducting an extensive literature search, in part 2 of this series we discuss the management of fluids and electrolytes, renal dysfunction; ascites, pleural effusion, and transfusion and coagulopathy issues in patients with VOD. We consider the available evidence using the GRADE criteria. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc. All rights reserved.

Magnetic resonance cholangiopancreatography (MRCP) is often used for imaging of the biliary tree and is required by surgeons before liver transplantation. Advanced liver cirrhosis and ascites in patients however present diagnostic problems for MRCP. The aim of this study was to find out if the use of our negative per-oral contrast agent containing superparamagnetic iron oxide nanoparticles (SPIO) in MRCP is helpful for imaging of hepatobiliary tree in patients with liver cirrhosis. Forty patients with liver cirrhosis were examined on a 1.5 T MR unit using standard MRCP protocol. Twenty patients (group A) underwent MRCP after administration of per-oral SPIO contrast agent 30 min before examination. In group B, twenty patients were examined without per-oral bowel preparation. Ascites was present in eleven patients from group A and in thirteen patients in group B. Four radiologists analyzed MR images for visibility and delineation of the biliary tree. χ 2 tests were used for comparison of the visibility of intrahepatic and extrahepatic biliary ducts in patients with and without ascites. Better extrahepatic biliary duct visualization and visibility of extraluminal pathologies in patients with ascites was proved after administration of SPIO contrast agent. No statistically significant difference between group A and B was found for visualization of extrahepatic biliary ducts in patients without ascites. Delineation of intrahepatic biliary ducts was independent on bowel preparation. Application of our negative per-oral SPIO contrast agent before MRCP improves the visualization of extrahepatic biliary ducts in patients with ascites which is helpful during the liver surgery, mainly in liver transplantation.

2002-12-15

We report the case of a 37-year-old man with necrotizing pancreatitis associated with inflammatory extrahepatic portal vein stenosis and progressive ascites. Four months after the acute onset, when no signs of infection were present, portal decompression was performed to treat refractory ascites. Transjugulartranshepatic venoplasty failed to dilate the stenosis in the extrahepatic portion of the portal vein sufficiently. Therefore a Wallstent was implanted, resulting in almost normal diameter of the vessel. In follow-up imaging studies the stent and the portal vein were still patent 12 months after the intervention and total resolution of the ascites was observed.

Quality control of murine monoclonal antibodies using isoelectric focusing affinity immunoblot analysis

Hamilton, Robert G.; Rodkey, L. Scott; Reimer, Charles B.

1987-01-01

The quality control of murine hybridoma secretory products has been performed using two approaches for isoelectric focusing affinity immunoblot analysis: (1) a method in which antigen-coated nitrocellulose is placed on top of an acrylamide gel containing isoelectrically focused ascites to bind the antigen specific monoclonal antibody; and (2) a method in which focused ascite proteins were passively blotted onto nitrocellulose and specific monoclonal antibodies were detected with enzyme-conjugated antigen. Analysis by both methods of batches of ascites containing antihuman IgG antibodies that were produced by six hybridomas permitted effective monitoring of immunoreactive antibodies for pI microheterogeneity.

Six mice were immunized intraperitoneally (i.p.) with a chemically synthesized 9-mer fragment (PH1) designed from the N-terminal part of the bacteriocin pediocin PA-1 and conjugated to keyhole limpet haemocyanin (KLH). After three doses of the immunogen had been administered, serum-specific antibodies were detected by a competitive direct ELISA. Myeloma cells were injected i.p. into mice in order to obtain ascites polyclonal antibodies. Although four mice developed ascites, only mouse 2 had detectable specific antibodies in the ascites fluid. The serum and ascites antibodies were specific for PH1 but they did not recognize the whole pediocin PA-1 molecule. This is the first attempt to generate antibodies against bacteriocins with a chemically synthesized oligopeptide as immunogen. This approach still remains attractive for detection, quantification, mode of action studies and purification of bacteriocins, especially those for which the purification process is difficult or inefficient at present.

[Routes of resorption of peritoneal fluid in the diaphragm in liver cirrhosis (morphologic study)].

Khoroshaev, V A; Vorozheĭkin, V M; Baĭbekov, I M

1991-01-01

The diaphragm peritoneum from 12 operated patients and 34 patients who died from liver cirrhosis with or without ascites was studied by means of light microscopy and electron transmission and scanning microscopy. Considerable lesions are found in the peritoneum: cuboidization of mesothelial cells, basal membrane thickening, dilation of stomata, lymphatic lacunae and collectors lumina. Liver cirrhosis with ascites is frequently followed by lymphatic vessels thrombosis and firm attachment of the diaphragm to the liver resulting in the inhibition of the ascitic liquid elimination. Thus both the enhancement of liquid transudation into the abdominal cavity and the disturbance of the drainage function of the diaphragm peritoneum take place.

Aberrantly activated FOXM1 (forkhead box protein M1) leading to uncontrolled cell proliferation and dysregulation of FOXM1 transcription network occurs in 84% of ovarian cancer cases. It was demonstrated that thiostrepton, a thiazole antibiotic, decreases FOXM1 expression. We aimed to determine if targeting the FOXM1 pathway with thiostrepton could improve the efficacy of paclitaxel and cisplatin in human ovarian cancer ascites cells ex vivo. Human ovarian cancer cell lines and patients' ascites cells were treated with paclitaxel, cisplatin, and thiostrepton or a combination for 48 hours, and cytotoxicity was assessed. Drug combination effects were determined by calculating the combination index values using the Chou and Talalay method. Quantitative reverse transcriptase-polymerase chain reaction was performed to determine changes in FOXM1 expression and its downstream targets. Ovarian cancer cell lines and the patients' ascites cancer cells had an overexpression of FOXM1 expression levels. Targeting FOXM1 with thiostrepton decreased FOXM1 mRNA expression and its downstream targets such as CCNB1 and CDC25B, leading to cell death in both cell lines and patients' ascites cancer cells. Furthermore, addition of thiostrepton to paclitaxel and cisplatin showed synergistic effects in chemoresistant ovarian cancer patients' ascites cells ex vivo. Targeting FOXM1 may lead to novel therapeutics for chemoresistant epithelial ovarian cancer.

Tjalma syndrome or pseudo-pseudo Meigs' syndrome is a clinical condition characterized by pleural effusion, ascites and elevated CA-125 with no associated benign or malignant ovarian tumor in a patient with systemic lupus erythematosus (SLE). Tjalma described the first case of a patient with SLE, pleural effusion, ascites and elevated CA-125. We report the first case in a 14-year old patient who presented with ascites and pleural effusion refractory to treatment and elevated CA-125, in the absence of an ovarian tumor, that warranted aggressive management.

Hutchison, Thomas W.S.; Riddell, Craig

1990-01-01

A detailed descriptive study was done on broiler chickens with abnormal livers found at processing. Two syndromes were evident: those birds with enlarged, pale, firm livers, designated hepatosis, with Clostridium perfringens type A often isolated; and ascitic birds with cobblestone-appearing livers. Livers with hepatosis had marked proliferation of bile ducts; ascitic livers had normal architecture. Hearts from birds with ascites had elevated right ventricular/total ventricular weight ratios, whereas hearts from normal birds and birds with hepatosis did not. Two isolates of C. perfringens produced necrotic enteritis in experimental birds; an attempt to reproduce hepatosis with these isolates was unsuccessful.

The current study was to prepare a mouse-derived antibody against the angiotensin II type 1 receptor (AT1-mAb) based on monoclonal antibody technology, to provide a foundation for research on AT1-AA-positive diseases. Balb/C mice were actively immunized with the second extracellular loop of the angiotensin II type 1 receptor (AT1R-ECII). Then, mouse spleen lymphocytes were fused with myeloma cells and monoclonal hybridomas that secreted AT1-mAb were generated and cultured, after which those in logarithmic-phase were injected into the abdominal cavity of mice to retrieve the ascites. Highly purified AT1-mAb was isolated from mouse ascites after injection with 1 × 107 hybridomas. A greater amount of AT1-mAb was purified from mouse ascites compared to the cell supernatant of hybridomas. AT1-mAb purified from mouse ascites constricted the thoracic aorta of mice and increased the beat frequency of neonatal rat myocardial cells via the AT1R, identical to the effects of AT1-AA extracted from patients' sera. Murine blood pressure increased after intravenous injection of AT1-mAb via the tail vein. High purity and good biological activity of AT1-mAb can be obtained from mouse ascites after intraperitoneal injection of monoclonal hybridomas that secrete AT1-mAb. These data provide a simple tool for studying AT1-AA-positive diseases. PMID:27057554

We have established an orthotopic nude-mouse model of gastric cancer carcinomatosis peritonitis, a recalcitrant disease in human patients. Human MKN45 poorly-differentiated human gastric cancer cells developed carcinomatosis peritonitis upon orthotopic transplantation in nude mice. The MKN45 cells expressed the fluorescent ubiquitination-based cell cycle indicator (FUCCI) that color codes the phases of the cell cycle. The intra-peritoneal tumors and ascites contained mostly quiescent G 1 /G o cancer cells visualized as red by FUCCI imaging. Cisplatinum (CDDP) treatment did not reduce bloody ascites, and larger tumors formed in the peritoneal cavity after CDDP treatment in an early-stage carcinomatosis peritonitis orthotopic mouse model. Paclitaxel-treated mice had reduced ascites, but also had large tumor masses in the peritonium after treatment with cancer cells mostly in G 0 /G 1 , visualized by FUCCI red. In contrast, OBP-301 telomerase-dependent adenovirus-treated mice had no ascites and only small tumor nodules consisting of cancer cells mostly in S/G 2 phases in the early-stage carcinomatosis peritonitis model, visualized by FUCCI green. Furthermore, OBP-301 significantly reduced the size of tumors (P < 0.01) and ascites even in a late-stage carcinomatosis peritonitis model. These results suggest that quiescent peritoneally-disseminated gastric cancer cells are resistant to conventional chemotherapy, but OBP-301 significantly reduced the weight of the tumors and increased survival, suggesting clinical potential.

Gastrodia elata Blume (G. elata) is a famous restorative food in East Asia. It can be used as an auxiliary reagent in hepatocellular carcinoma (HCC) treatment. Previous studies unveiled that G. elata exhibited immunomodulatory activities. To explore the active ingredients contributing to its immunomodulatory activities, gastrodin, vanillin, and parishin B were purified from G. elata and their anti-HCC effects were assessed in vivo. Among these compounds, only gastrodin was capable of repressing transplanted H22 ascitic hepatic tumor cell growth in vivo with low toxicity. Further investigations were designed to explore the effects of gastrodin on the immune system of tumor-bearingmore » mice and potential molecular mechanisms underlying these effects. Our data showed that gastrodin ameliorated tumor cell transplantation-induced activation of endogenous pro-apoptotic pathway in CD4 + T cells and abnormalities in serum cytokine profiles in host animals. These events enhanced cytotoxic activities of natural killer and CD8 + T cells against H22 hepatic cancer cells. Gastrodin administration specifically upregulated mRNA levels of several nuclear factor κB (NF-κB) responsive genes in CD4 + T cells but not in CD8 + T cells. Chromatin immunoprecipitation assay showed that gastrodin increased the association of NF-κB p65 subunit to the promoter regions of IL-2 and Bcl-2 encoding genes in CD4 + T cells. Our investigations demonstrated that gastrodin is the main active ingredient contributing to the anticancer immunomodulatory properties of G. elata. Promoting NF-κB-mediated gene transcription in CD4 + T cells is implicated in its immunomodulatory activity. - Highlights: • Gastrodin stimulates anticancer immune response. • Gastrodin represses tumor transplantation-induced CD4 + T cell apoptosis. • Gastrodin activates NF-κB activity in CD4 + T cells.« less

Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv.

Transforming growth factor beta (TGFβ) is a family of genes that play a key role in mediating tissue remodeling in various forms of acute and chronic lung disease. In order to assess their role on pulmonary hypertension in broilers, we determined mRNA expression of genes of the TGFβ family and endothelin 1 in lung samples from 4-week-old chickens raised either under normal or cold temperature conditions. Both in control and cold-treated groups of broilers, endothelin 1 mRNA expression levels in lungs from ascitic chickens were higher than levels from healthy birds (P < 0.05), whereas levels in animals with cardiac failure were intermediate. Conversely, TGFβ2 and TGFβ3 gene expression in lungs were higher in healthy animals than in ascitic animals in both groups (P < 0.05). TGFβ1, TβRI, and TβRII mRNA gene expression among healthy, ascitic, and chickens with cardiac failure showed no differences (P > 0.05). BAMBI mRNA gene expression was lowest in birds with ascites only in the control group as compared with the values from healthy birds (P < 0.05). PMID:24286074

A 66-year-old woman was admitted to our clinic for appetite loss and abdominal distension in August 1995. Endoscopic study revealed an advanced gastric cancer in the upper body of her stomach. Abdominal CT study revealed massive ascites and para-aortic lymph nodal involvement. Cytological study of the ascites revealed class V. She was diagnosed to be in the terminal stage of gastric cancer with carcinomatosa peritonitis. Combination chemotherapy with 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) was given by continuous intravenous injection of 5-FU 500 mg/day, and intermittent intravenous injection of CDDP 30 mg/week was performed for reduction of the ascites and her complaint. Endoscopic study 6 weeks after starting chemotherapy could not find crater of the gastric cancer but only a shallow ulcerative lesion. The biopsy specimen of that lesion was group III. No ascites and over 50% reduction of the para-aortic lymph node were found by the abdominal CT study. This state persisted over 4 weeks. No myelo-suppression, renal dysfunction or any severe side effect were observed during chemotherapy. Her performance status improved from 3 to 1.

Increased pro-brain natriuretic peptide (pro-BNP) or troponin T-hypersensitivity (TnT-HSST) levels are common in liver cirrhosis. We conducted a retrospective observational study aimed to evaluate the correlation of pro-BNP and TnT-HSST levels with the clinical characteristics, laboratory data and in-hospital outcomes of patients with liver cirrhosis. We selected cirrhotic patients admitted to our hospital between January 2011 and June 2014. All eligible patients had pro-BNP or TnT-HSST data, or both. The pro-BNP and TnT-HSST data were further divided according to the presence of cardiac diseases. The prevalence of pro-BNP level >900pg/mL was 41.72% (63 of 151 patients). The prevalence of TnT-HSST level >0.05ng/mL was 11.22% (45 of 401 patients). In the overall analysis, pro-BNP level significantly correlated with red blood cell (RBC), platelet, ascites, blood urea nitrogen (BUN), creatinine (Cr), Child-Pugh score, model for end-stage liver disease (MELD) score and in-hospital death; TnT-HSST level significantly correlated with white blood cell, ascites, albumin (ALB), BUN, Cr, Child-Pugh score, MELD score and in-hospital death. In patients with cardiac diseases, pro-BNP level significantly correlated with RBC, ascites, BUN, Cr, Child-Pugh score and MELD score; TnT-HSST level significantly correlated with sex, ascites, white blood cell, ALB, BUN, Cr, Child-Pugh score, MELD score and in-hospital death. In patients without cardiac diseases, pro-BNP level significantly correlated with ascites, RBC, platelet, BUN, Cr, MELD score and in-hospital death; TnT-HSST level significantly correlated with age, ascites, RBC, ALB, BUN, Cr, Child-Pugh score, MELD score and in-hospital death. Pro-BNP and TnT-HSST levels significantly correlated with the severity of liver dysfunction and in-hospital mortality in cirrhosis. Copyright © 2017 Southern Society for Clinical Investigation.

The aim of this study is the evaluation of laparoscopic treatment in abdominal complications following ventriculoperitoneal (VP) shunt. Methods: We report a retrospective study including 17 patients with abdominal complications secondary to VP shunt for hydrocephalus, laparoscopically treated in our department, between 2000 and 2007. Results: Patients' age ranged from 1 to 72 years old (mean age 25.8 years old). Male: female ratio was 1.4. Abdominal complications encountered were: shunt disconnection with intraperitoneal distal catheter migration 47.05% (8/17), infections 23.52% (4/17) such as abscesses and peritonitis, pseudocysts 11.76% (2/17), CSF ascites 5.88% (1/17), inguinal hernia 5.88% (1/17), and shunt malfunction due to excessive length of intraperitoneal tube 5.88% (1/17). Free–disease interval varies from 1 day to 21 years, depending on the type of complication, short in peritoneal irritation syndrome and abscesses (days) and long in ascites, pseudocysts(months– years). Laparoscopic treatment was: extraction of the foreign body in shunt disconnection with intraperitoneal distal catheter migration, evacuation, debridement, lavage and drainage for pseudocysts, abscess and peritonitis, shortening of the tube in shunt malfunction due to excessive length of intraperitoneal tube a nd hernioraphy. One diagnostic laparoscopy was performed in a peritoneal irritation syndrome, which found only CSF ascites. There were no conversions to open surgery. The overall mortality was of 5.88% and postoperative morbidity was of 11.76%. In 7 patients operated for abscesses, peritonitis, pseudocysts, and CSF ascites the shunting system was converted in to a ventriculocardiac shunt. Conclusions: Abdominal complication following VP shunt can be successfully performed laparoscopically. Abdominal surgery required, in selected cases, the repositioning of the distal catheter, frequently as a ventriculocardiac shunt. There are abdominal complications with no indication of

Meigs' syndrome is defined as the co-existence of benign ovarian fibroma or fibroma-like tumor, ascites, and pleural effusion. In contrast, pseudo-Meigs' syndrome is defined as the co-existence of other ovarian or pelvic tumors, ascites, and pleural effusion. In Meigs' and pseudo-Meigs' syndromes, ascites and pleural effusion resolve promptly after the complete resection of the ovarian or pelvic tumor(s). Secondary ovarian tumors from colorectal gastrointestinal metastases rarely cause pseudo-Meigs' syndrome; only 11 cases of pseudo-Meigs' syndrome secondary to colorectal cancers have been reported in the literature. Therefore, the prognosis and etiology of pseudo-Meigs' syndrome caused by ovarian metastasis from colorectal cancers remain unclear. We report here a rare case of pseudo-Meigs' syndrome caused by ovarian metastases from sigmoid colon cancer with long-term survival. A 47-year-old woman presented with abdominal distention of 1-month duration. She developed acute dyspnea 2 weeks after the initial presentation. Colonoscopy and computed tomography revealed sigmoid colon cancer with an ovarian metastasis, along with massive ascites and bilateral pleural effusion. Emergency operation, including bilateral oophorectomy and sigmoidectomy, was performed. Subsequently, ascites and bilateral pleural effusion resolved rapidly. Curative hepatic resection was performed for liver metastases 29 months after the first operation, and as of this writing, the patient is alive with no evidence of a disease 78 months after the first operation. In general, colorectal cancer with ovarian metastasis is hard to cure, and long-term survival in patients with colorectal cancer with pseudo-Meigs' syndrome is rare. Our experience suggests that curative resection for pseudo-Meigs' syndrome caused by ovarian metastasis from colorectal cancer may offer long-term survival. Our experience suggests that pseudo-Meigs' syndrome can occur in a patient with colorectal cancer after metastasis

The objective of this study was to determine the influence of pleural and ascitic fluid on the pharmacokinetics of the antitumor camptothecin derivative topotecan. Four patients with histological proof of malignant solid tumor received topotecan (0.45 or 1.5 mg/m2) p.o. on several occasions in both the presence and absence of third space volumes. Serial plasma and pleural or ascitic fluid samples were collected during each dosing and analyzed by high-performance liquid chromatography for both the intact lactone form of topotecan and its ring-opened carboxylate form. The apparent topotecan clearance demonstrated substantial interpatient variability but remained unchanged within the same patient in the presence [110 +/- 55.6 liters/ h/m2 (mean +/- SD of eight courses)] or absence of pleural and ascitic fluid [118 +/- 31.1 liters/h/m2 (mean +/- SD of seven courses)]. Similarly, terminal half-lives and area under the concentration-time curve ratios of lactone:total drug in plasma were similar between courses within each patient. Topotecan penetration into pleural and ascitic fluid demonstrated a mean lag time of 1.61 h (range, 1.37-1.86 h), and ratios with plasma concentration increased with time after dosing in all patients. The mean ratio of third space topotecan total drug area under the concentration-time curve to that in plasma was 0.55 (range, 0.26-0.87). These data indicate that topotecan can be safely administered to patients with pleural effusions or ascites and that there is substantial penetration of topotecan into these third spaces, which may prove beneficial for local antitumor effects.

Spontaneous bacterial peritonitis (SBP) is a common and important clinical problem and is life-threatening in decompensated liver disease. Ascites fluid test by leukocyte esterase test strip has been recently proposed as an effective and rapid method to diagnose SBP in patients with cirrhosis. This study aimed to evaluate sensitivity and specificity of leukocyte esterase test strip in the diagnosis of SBP. The population of this research was all patients with cirrhosis and ascites admitted to the emergency room at Imam Reza (AS) hospital, Mashhad. A written consent was taken for inclusion in the study. 50 mL ascites sample was taken from all patients for use in a urine test strip (LER) (Urine Test Strips Convergys®Urine Matrix 11). The patient's ascites samples were evaluated for cell counting. Positive dipstick test for LER in this study considered as grade 3 +. The values of WBC > 500 cell/mm(3) or PMN > 250 cell/mm(3) considered as positive result of the gold standard method for the diagnosis of SBP. In this study, 100 patients with ascites due to cirrhosis, with an average age of 38.9 ± 6.54 years were evaluated. Twenty cases had positive results, of whom 17 cases were also detected based on the standard diagnostic criteria and other three cases were healthy individuals. Thus, sensitivity, specificity, positive and negative predictive values, and accuracy of the method were 95%, 96.3%, 85%, 97.5% and 95%, respectively. The use of leukocyte esterase urine dipstick test can be a quick and easy method in early diagnosis of SBP to start the treatment until preparation of SBP-cell count results.

Post-transplantation portal hypertension has severe complications, such as esophageal varix bleeding, therapy refractory ascites, extreme splenomegaly, and graft dysfunction. The aim of our study was to analyze the effectiveness of the therapeutic strategies and how to visualize the procedure. A retrospective study involving liver transplantation patients from the Semmelweis University Department of Transplantation and Surgery was performed between 2005 and 2015. The prevalence, etiology, and leading complications of the condition were determined. The applied interventions' effects on the patients' ascites volume, splenic volume, and the occurrence of variceal bleeding were determined. Mean portal blood flow velocity and congestion index values were calculated using Doppler ultrasonography. The prevalence of post-transplantation portal hypertension requiring intervention was 2.8%. The most common etiology of the disease was portal anastomotic stenosis. The most common complications were esophageal varix bleeding and therapy refractory ascites. The patients' ascites volume decreased significantly (2923.3 ± 1893.2 mL vs. 423.3 ± 634.3 mL; P < .05), their splenic volume decreased markedly. After the interventions, only one case of recurrent variceal bleeding was reported. The calculated Doppler parameters were altered in the opposite direction in cases of pre-hepatic versus intra- or post-hepatic portal hypertension. After the interventions, these parameters shifted towards the physiologic ranges. The interventions performed in our clinic were effective in most cases. The patients' ascites volume, splenic volume, and the prevalence of variceal bleeding decreased after the treatment. Doppler ultrasonography has proved to be a valuable imaging modality in the diagnosis and the follow-up of post-transplantation portal hypertension. Copyright © 2017 Elsevier Inc.

Acute umbilical hernia rupture in patients with hepatic cirrhosis and ascites is an unusual, but potentially life-threatening complication, with postoperative morbidity about 70% and mortality between 60%-80% after supportive care and 6%-20% after urgent surgical repair. Management options include primary surgical repair with or without concomitant portal venous system decompression for the control of the ascites. We present a retrospective analysis of our centre’s experience over the last 6 years. Our cohort consisted of 11 consecutive patients (median age: 53 years, range: 36-63 years) with advanced hepatic cirrhosis and refractory ascites. Appropriate patient resuscitation and optimisation with intravenous fluids, prophylactic antibiotics and local measures was instituted. One failed attempt for conservative management was followed by a successful primary repair. In all cases, with one exception, a primary repair with non-absorbable Nylon, interrupted sutures, without mesh, was performed. The perioperative complication rate was 25% and the recurrence rate 8.3%. No mortality was recorded. Median length of hospital stay was 14 d (range: 4-31 d). Based on our experience, the management of ruptured umbilical hernias in patients with advanced hepatic cirrhosis and refractory ascites is feasible without the use of transjugular intrahepatic portosystemic shunt routinely in the preoperative period, provided that meticulous patient optimisation is performed.

Outbreaks of serious mortality among cultured juvenile cobia Rachycentron canadum L. (weighing 8-10 g) characterized by lethargy, dark skin and ascites in the peritoneal cavity while some fish possessing damaged eyes occurred in July and August of 2001 in Taiwan. Fifteen motile bacterial strains were isolated from head kidney and/or the ascites on tryptic soy agar supplemented with 1% NaCl (TSA1) and/or thiosulphate citrate bile salt (TCBS) sucrose agar plates during the two outbreaks. All the isolates were characterized and identified as Vibrio alginolyticus on the basis of biochemical characteristics, and comparisons with those of the reference strain V. alginolyticus ATCC 17749. The strain C3c01 (a representative of the 15 similar field isolates), was virulent to the cobia with an LD50 value of 3.28 x 10(4) colony forming units/g fish body weight. All the moribund/dead fish exhibited lethargy, dark skin and ascites in the peritoneal cavity as that observed in natural outbreaks. The same bacteria could be reisolated from kidney and the ascites of fish after bacterial challenge using TSA1 and TCBS plates. The results reveal that V. alginolyticus is an infectious agent of vibriosis in the cobia.

Sclerosing peritonitis is a rare condition characterised by ascites, peritoneal and bowel wall thickening. Causes reported in the literature include luteal ovarian the comas, peritoneal dialysis, peritoneal chemotherapy and liver cirrhosis. We report an interesting case of a woman presenting with diarrhoea, abdominal distension, ascites and pleural effusion. She was subsequently diagnosed with Sclerosing Peritonitis caused by a degenerating fibroid which was successfully treated by Total Abdominal Hysterectomy and Bilateral Salpingoophrectomy.

The purpose of this study was to develop a safe and non-toxic alternative to the conventional conservative treatment of peritoneal carcinomatosis with malignant ascites (PCMA) by investigating the efficacy and safety of local modulated electro-hyperthermia (mEHT) combined with the traditional Chinese medicine (TCM) ‘Shi Pi’ herbal decoction, compared with standard intraperitoneal chemoinfusion (IPCI). A randomized, controlled, single-center, open-label clinical trial (phase II) with two parallel groups (allocation ratio, 1:1) was conducted to investigate the efficacy and safety of mEHT+TCM (study group, SG) vs. standard IPCI (control group, CG) in patients with PCMA by intention-to-treat analysis. A total of 260 patients with PCMA were randomly allocated into the two groups (130/130); mEHT was applied for 60 min per session every second day for 4 weeks, for a total of 14 sessions. The TCM decoction was administered orally, at 400 ml daily. In CG, occlusive IPCI with cisplatin (30–60 mg) and fluorouracil (500–600 mg/m2) was applied twice, biweekly. The objective response rate (ORR), quality of life (QoL) and adverse event rate (AER) in the two groups were evaluated 1 month after treatment, analyzed and compared. The present study is registered on ClinicalTrials.gov (NCT02638051). No case was lost or excluded (0/260). The ORR in SG was 77.69% (101/130) vs. 63.85% (73/130) in CG (P<0.05). The QoL in SG was 49.23% vs. 32.3% in CG (P<0.05). The AER in SG was 2.3% (3/130) vs. 12.3% (16/130) in CG (P<0.05). All the adverse events were grade I. In conclusion, the combination of mEHT with TCM achieves better control of PCMA compared with standard IPCI, with less toxicity. Both components of the combination are non-toxic treatments easily tolerated by patients. Thus, this combined treatment may be preferred due to the better benefit-harm balance. PMID:28529748

Peritoneal carcinomatosis is considered as a potentially lethal clinical condition, and the therapeutic options are limited. The antitumor effectiveness of the [Ru(l-Met)(bipy)(dppb)]PF 6 (1) and the [Ru(l-Trp)(bipy)(dppb)]PF 6 (2) complexes were evaluated in the peritoneal carcinomatosis model, Ehrlich ascites carcinoma-bearing Swiss mice. This is the first study that evaluated the effect of Ru(II)/amino acid complexes for antitumor activity in vivo. Complexes 1 and 2 (2 and 6 mg kg -1 ) showed tumor growth inhibition ranging from moderate to high. The mean survival time of animal groups treated with complexes 1 and 2 was higher than in the negative and vehicle control groups. The induction of Ehrlich ascites carcinoma in mice led to alterations in hematological and biochemical parameters, and not the treatment with complexes 1 and 2. The treatment of Ehrlich ascites carcinoma-bearing mice with complexes 1 and 2 increased the number of Annexin V positive cells and cleaved caspase-3 levels and induced changes in the cell morphology and in the cell cycle phases by induction of sub-G1 and G0/G1 cell cycle arrest. In addition, these complexes reduce angiogenesis induced by Ehrlich ascites carcinoma cells in chick embryo chorioallantoic membrane model. The treatment with the LAT1 inhibitor decreased the sensitivity of the Ehrlich ascites carcinoma cells to complexes 1 and 2 in vitro-which suggests that the LAT1 could be related to the mechanism of action of amino acid/ruthenium(II) complexes, consequently decreasing the glucose uptake. Therefore, these complexes could be used to reduce tumor growth and increase mean survival time with less toxicity than cisplatin. Besides, these complexes induce apoptosis by combination of different mechanism of action.

Cholera toxin activation of adenylate cyclase in cancer cell membrane fragments.

Activation of adenylate [ATP pyrophosphate-lyase (cyclizing), EC 4.6.1.1] by cholera toxin (84,000 daltons, 5.5 S) is demonstrated in plasma membrane fragments of mouse ascites cancer cells. The activation of adenylate cyclase is mediated by a macromolecular cyclase activating factor (MCAF), which has a sedimentation constant of 2.7 S and a molecular weight of about 26,000. MCAF is derived from, and may be identical to the "A fragment" of cholera toxin. Generation of MCAF depends on prior interaction of cholera toxin with either dithiothreitol, NADH, NAD, or a low-molecular-weight component (less than 700 daltons) present in cytoplasm. Subsequent exposure of this pretreated cholera toxin to cell membranes from a variety of mouse ascites cancer cells is followed rapidly by the appearance of MCAF, which no longer requires dithiothreitol, NADH, or NAD for the activation of adenylate cyclase. Activation of adenylate cyclase by MCAF in ascites cancer cell membrane fragments is not reversed by repeated washing of these membrane fragments. Adenylate cyclase in normal cell membrane fragments fails to respond either to cholera toxin or MCAF in the presence of dithiothreitol. In striking contrast, the adenylate cyclase in membrane fragments from five ascites cancer cells responds to either MCAF or native cholera toxin preincubated with dithiothreitol, NADH, or NAD.

Peritoneal effusion appears to be an unusual complication of infectious mononucleosis (IM). The cytological features of peritoneal effusion from a patient affected by IM are presented. The patient was a 21-year-old Japanese woman, with typical and physical findings of IM. Ascites disappeared with resolution of acute IM. The cytospin smears of the ascitic fluid were highly cellular, consisting exclusively of lymphoid cells. Lymphoid cells were composed of large cells with broad basophilic cytoplasm, as well as of small to medium-sized cells having scant cytoplasm and irregularly shaped nuclei. The overall cytomorphological pictures posed serious difficulties in differentiating this condition from those of peripheral T-cell lymphomas manifesting ascites. The majority of atypical lymphocytes, including large cells, expressed CD3 and CD8. The present case indicates that IM should be added to the list of lesions considered for the differential diagnosis of non-Hodgkin's lymphoma of the peritoneal fluid, particularly regarding young adults.

Pseudo-Meigs’ syndrome associated with colorectal cancer is extremely rare. We report here a case of pseudo-Meigs’ syndrome secondary to metachronous ovarian metastases from colon cancer. A 65-year-old female with a history of surgery for transverse colon cancer and peritoneal dissemination suffered from metachronous ovarian metastases during treatment with systemic chemotherapy. At first, neither ascites nor pleural effusion was observed, but she later complained of progressive abdominal distention and dyspnea caused by rapidly increasing ascites and pleural effusion and rapidly enlarging ovarian metastases. Abdominocenteses were repeated, and cytological examinations of the fluids were all negative for malignant cells. We suspected pseudo-Meigs’ syndrome, and bilateral oophorectomies were performed after thorough informed consent. The patient’s postoperative condition improved rapidly after surgery. We conclude that pseudo-Meigs’ syndrome should be included in the differential diagnosis of massive or rapidly increasing ascites and pleural effusion associated with large or rapidly enlarging ovarian tumors.

2012-01-01

Pulmonary giant cell carcinoma is a rare subtype of sarcomatoid carcinoma. Pseudomyxoma peritonei (PMP) is a rare condition in which gelatinous material accumulates within the peritoneal cavity. It is believed PMP arises from a primary appendiceal mucinous neoplasm that perforates the gut, causing mucinous ascites. There are sporadic reports of PMP associated with neoplasms of other organs, rarely the lung. Here, we report on a 60-year-old woman with pulmonary giant cell carcinoma associated with PMP. She presented with progressive dyspnea and abdominal distention. Abdominal computed tomography revealed moderately dense ascites without an obvious mass. Chest computed tomography revealed a large, solitary right lower-lobe lung mass. She underwent transbronchial fine-needle aspiration of the mass, and was diagnosed with pulmonary giant cell carcinoma. The ascites showed scattered malignant cells in a background of mucin, confirming PMP. To our knowledge, this is the first report of pulmonary giant cell carcinoma associated with PMP.

Massive vulvar edema in a woman with preeclampsia preceded the development of massive ascites and impending eclampsia. A 17-year-old preeclamptic, primiparous woman was admitted with preeclampsia and massive vulvar edema. Other causes were excluded. The vulvar edema increased as the blood pressure and ascites increased, and a severe headache developed. Cesarean section for increasing preclampsia was performed. In the puerperium, the blood pressure improved and vulvar edema resolved. The clinical picture of the vulvar edema correlated with the severity of the preeclampsia. The presence of vulvar edema in women with preeclampsia should indicate immediate admission to the hospital. These patients must be considered as at high risk, and close monitoring must be instituted. In our case, vulvar edema preceded massive ascites development. We assume a common development mechanism for these signs in preeclampsia, due mainly to increased capillary permeability and hypoalbuminemia. The attending physician must be prepared for immediate delivery and possible preeclampsia complications in these patients.

Catumaxomab, a monoclonal bispecific trifunctional antibody, was approved in the european Union in April 2009 for the intraperitoneal treatment of patients with malignant ascites. The marketing authorization holder Fresenius Biotech GmbH developed catumaxomab (Removab®) together with its partner TRiOn Pharma GmbH, Germany. it is the first substance worldwide with a regulatory label for the treatment of malignant ascites due to epithelial carcinomas. Since the peritoneum is of mesothelial origin and therefore lacks epCAM expression, the intraperitoneal administration of catumaxomab is an attractive targeted immunotherapeutic approach. Catumaxomab is able to destroy epCAM positive tumor cells in the peritoneal cavity known as the main cause of malignant ascites. in addition, catumaxomab is a potential therapeutic option for several primary tumors since the epCAM molecule is expressed on the majority of epithelial carcinomas. This review focuses on the clinical development of catumaxomab and indicates future directions. PMID:20190561

A female infant with extralobar lung sequestration (ELS) combined with bilateral hydrothorax and ascites is presented. A 34-year-old para II, pregnant in the 29th gestation week, was referred to hospital because of acute hydramnios. Ultrasound examination demonstrated marked hydramnios, together with ascites and bilateral pleural effusion in the fetus. In the amniotic fluid, alfafetoprotein was found normal and the karyotype showed a normal chromosome pattern, 46 xx. The hydramnios was so severe and the cervix so unripe, that cesarean section had to be undertaken, and a girl of 1650 g, and 42 cm long was born. Just after delivery the infant had bradycardia, cyanosis and respiratory insufficiency, with Apgar score 2 during the first 15 min. Manual ventilation followed by Servo respirator with 100% oxygen was given, but with poor effect. The infant lived only 6 3/4 hours. At autopsy there was hydrothorax, bilateral collapsed lungs and ascites and ELS as the only congenital malformation.

The main goal of our study was to evaluate cirrhosis course on one year. The study was prospective and longitudinal from January 2005 to December 2006 in the center of hepatology and gastro-enterology of CHU Gabriel Touré. The patients had one year follow up and examinated every three months. In this study 57 patients were included. Mean age was 41,5 + 15,3 years. Ascite and jaundice were the main clinical signs respectively 70.2% and 54.4%. Ascite or its increase was the most complication in 67.5% of cases (p = 0.002). The global mortality was 82.5% and it was high in the three first months, caused by hepatocellular carcinoma, digestive bleeding and hepatic encephalopathy respectively 33.3%, 27.3% and 15.2%. Abdomen pain, ascite and jaundice have an predictive value for high mortality (p between 3.10-3 et 10-7). Early examination, therapeutic observance and good management of cirrhosis complications could reduce the mortality.

Listeria monocytogenes-induced monomicrobial non-neutrocytic bacterascites.

Spontaneous bacterial peritonitis (SBP) is a common complication in patients with cirrhosis of the liver. The organisms most commonly involved in this infection are gram-negative bacteria like Escherichia coli and Klebsiella pneumoniae, and gram-positive bacteria like Streptococcus pneumoniae and Staphylococcus aureus. Listeria monocytogenes is an uncommon gram-positive bacillus implicated in infections in neonates, pregnant females, the elderly, and immunocompromised patients. Listeria monocytogene-induced SBP is rare, with less than 40 cases reported in the medical literature. Monobacterial non-neutrocytic bacterascites (MNB) is a variant of SBP, where the ascitic fluid culture is positive but the ascitic neutrophil count is less than 250/mm3. Forty percent of these patients will subsequently have SBP. Only 2 cases of MNB from L monocytogenes have previously been reported. We report a case of MNB in a patient with cirrhosis whose ascitic neutrophil count was 164/mm', but Gram stain and microbiologic culture showed the growth of L monocytogenes.

The creation of a transjugular intrahepatic portosystemic shunt (TIPS) is a critical procedure for the treatment of recurrent variceal bleeding and refractory ascites in the setting of portal hypertension. Chronic portal vein thrombosis remains a relative contraindication to conventional TIPS and options are limited in this scenario. Presented is a novel technique for management of refractory ascites in a patient with hepatitis C cirrhosis and chronic portal and superior mesenteric vein thrombosis secondary to schistosomiasis and lupus anticoagulant utilizing fluoroscopically guided percutaneous mesocaval shunt creation.

AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation. METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index (BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease (MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure (MIP) and maximal expiratory pressure, spirometry, root mean square (RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference (P = 0.01) between the first (initial) and the third month (final) MIP in the control group and in the intervention group, but there was no difference (P = 0.45) between the groups. The RMS of the diaphragm was lower (P = 0.001) and the functional capacity was higher (P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group (P = 0.01) and the intervention group (P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group (P = 0.083) and intervention group (P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups (P = 0.21). In the intervention group, patients with

Demons-Meigs' syndrome is characterized by the presence of a benign ovarian tumor associated with ascites and a right-sided hydrothorax. Its pathophysiology remains unclear. Anesthesia of this syndrome is a real challenge. Respiratory, hemodynamic, metabolic problems and abdominal hypertension are the main anesthetic risks. A 52-year-old African woman with Demons-Meigs' syndrome was admitted for elective surgery under general anesthesia. An abdominal computed tomography scan showed a tumor mass, with tissue and cystic components associated with abundant ascites and a right pleural effusion of medium abundance. In the operating room after standard monitoring, a crash induction was performed. Just after, her saturation level decreased requiring the use of an alveolar recruitment maneuver followed by the application of positive end-expiratory pressure. Vasoconstrictor and vascular filling were used to correct the hypotension that occurred. Airway pressures remained at 35 cm H2O. Maintenance of a slightly proclive position and opening of the abdomen with the progressive removal of 3200 ml ascitic fluid allowed a lower thoracic pressure (airway pressures=24 cm H2O). Her postoperative course was unremarkable. Clinical evolution after five months was marked by a complete recovery of our patient and no recurrence of effusion or ascites. Demons-Meigs' syndrome is a benign disease with a good prognosis. Respiratory and hemodynamic problems and abdominal hypertension are the main anesthetic risks of this syndrome. Good management of these risks is necessary to preserve the prognosis.

Bacterial translocation (BT) may cause infections, in particular, spontaneous bacterial peritonitis (SBP). In the absence of overt infection, BT may further stimulate the immune system and contribute to haemodynamic alterations and complications. Bacterial DNA (bDNA) is claimed to be a promising surrogate marker for BT, although its clinical relevance has been questioned. In 38 cirrhotic patients with and without SBP, bDNA in blood and ascites were assessed by 16S rDNA quantitative PCR. Levels of lipopolysaccharide-binding protein in plasma and highly sensitive C-reactive protein, tumour necrosis factor-α, soluble urokinase plasminogen activating receptor, interleukin-6, interleukin 8, interferon-γ inducible protein-10 and vascular endothelial growth factor in plasma and ascites were measured by multiplex cytokine and ELISA assays. In patients without signs of SBP or positive cultures, we found a high frequency of bDNA but low concordance of bDNA between blood and ascites. Markers of inflammation were not significantly different between blood bDNA-positive (22%), ascites bDNA-positive (52%), and bDNA-negative patients. The 16S rDNA PCR failed to show bDNA in two out of six samples with SBP. Sequencing of positive samples did not determine the source of bDNA. bDNA as assessed by this PCR method was largely unrelated to markers of inflammation and does not seem to be of clinical value in the diagnosis of SBP. According to our results, bDNA is not a reliable marker of BT.

To present a dedicated series of transjugular intrahepatic porto-systemic shunts (TIPS) in the elderly since data is sparse on this population group. A retrospective review was performed of patients at least 65 years of age who underwent TIPS at our institutions between 1997 and 2010. Twenty-five patients were referred for TIPS. We deemed that 2 patients were not considered appropriate candidates due to their markedly advanced liver disease. Of the 23 patients suitable for TIPS, the indications for TIPS placement was portal hypertension complicated by refractory ascites alone (n = 9), hepatic hydrothorax alone (n = 2), refractory ascites and hydrothorax (n = 1), gastrointestinal bleeding alone (n = 8), gastrointestinal bleeding and ascites (n = 3). Of these 23 attempted TIPS procedure patients, 21 patients had technically successful TIPS procedures. A total of 29 out of 32 TIPS procedures including revisions were successful in 21 patients with a mean age of 72.1 years (range 65-82 years). Three of the procedures were unsuccessful attempts at TIPS and 8 procedures were successful revisions of our existing TIPS. Sixteen of 21 patients who underwent successful TIPS (excluding 5 patients lost to follow-up) were followed for a mean of 14.7 mo. Ascites and/or hydrothorax was controlled following technically successful procedures in 12 of 13 patients. Bleeding was controlled following technically successful procedures in 10 out of 11 patients. We have demonstrated that TIPS is an effective procedure to control refractory complications of portal hypertension in elderly patients.

Improvement of macrophage dysfunction by administration of anti-transforming growth factor-beta antibody in EL4-bearing hosts.

PubMed

Maeda, H; Tsuru, S; Shiraishi, A

1994-11-01

An experimental therapy for improvement of macrophage dysfunction caused by transforming growth factor-beta (TGF-beta) was tried in EL4 tumor-bearing mice. TGF-beta was detected in cell-free ascitic fluid from EL4-bearers, but not in that from normal mice, by western blot analysis. The ascites also showed growth-suppressive activity against Mv1Lu cells, and the suppressive activity was potentiated by transient acidification. To investigate whether the functions of peritoneal macrophages were suppressed in EL4-bearers, the abilities to produce nitric oxide and tumor necrosis factor-alpha (TNF-alpha) upon lipopolysaccharide (LPS) stimulation were measured. Both abilities of macrophages in EL4-bearing mice were suppressed remarkably on day 9, and decreased further by day 14, compared with non-tumor-bearing controls. TGF-beta activity was abrogated by administration of anti-TGF-beta antibody to EL4-bearing mice. While a large amount of TGF-beta was detected in ascitic fluid from control EL4-bearers, little TGF-beta was detectable in ascites from EL4-bearers given anti-TGF-beta antibody. Furthermore, while control macrophages exhibited little or no production of nitric oxide and TNF-alpha on LPS stimulation in vitro, macrophages from EL4-bearers administered with anti-TGF-beta antibody showed the same ability as normal macrophages. These results clearly indicate that TGF-beta contributes to macrophage dysfunction and that the administration of specific antibody for TGF-beta reverses macrophage dysfunction in EL4-bearing hosts.

We present two cases of umbilical hernia incarceration following large volume paracentesis (LVP) in patients with cirrhotic ascites. Both patients became symptomatic within 48 hours after the LVP. Although being rare, given the significantly higher mortality rate of cirrhotic patients undergoing emergent herniorrhaphy, this complication of LVP is potentially serious. Therefore, it is recommended that patients be examined closely for the presence of umbilical hernias before removal of ascitic fluid and an attempt should be made for external reduction of easily reducible hernias, if a hernia is present.

Although being rare, given the significantly higher mortality rate of cirrhotic patients undergoing emergent herniorrhaphy, this complication of LVP is potentially serious. Therefore, it is recommended that patients be examined closely for the presence of umbilical hernias before removal of ascitic fluid and an attempt should be made for external reduction of easily reducible hernias, if a hernia is present.

Ovarian cancer is a prevalent gynecological malignancy with potent immune-suppression capabilities; regulatory T cells (Tregs) are significant contributors to this immune-suppression. As ovarian cancer patients present with high levels of TNF and Tregs expressing TNFR2 are associated with maximal suppressive capacity, we investigated TNFR2+ Tregs within these patients. Indeed, TNFR2+ Tregs from tumor-associated ascites were the most potent suppressor T cell fraction. They were abundantly present within the ascites and more suppressive than peripheral blood TNFR2+ Tregs in patients. The increased suppressive capacity can be explained by a distinct cell surface expression profile, which includes high levels of CD39, CD73, TGF-β and GARP. Additionally, CD73 expression level on TNFR2+ Tregs was inversely correlated with IFN-γ production by effector T cells. This Treg fraction can be selectively recruited into the ascites from the peripheral blood of patients. Targeting TNFR2+ Tregs may offer new approaches to enhance the poor survival rates of ovarian cancer. © 2013.

To document our experience with the use of the Bonanno catheter as a closed abdominal drain for OHSS Methods: A retrospective study of all IVF embryo transfer (ET) treatment cycles carried out between May 2006 and April 2009 at a dedicated IVF centre. Case notes of patients with OHSS were retrieved and the outcome of the continuous closed abdominal drain with Bonanno catheter documented. Within the period under review, 234 patients had controlled ovarian stimulation with ultrasound guided egg retrieval. Two hundred and twenty eight (228) got to the stage of embryo transfer with 72 clinical pregnancies. The clinical pregnancy rate was 31.58%. Fourteen (6%) of those who were stimulated developed OHSS and had a closed abdominal drain of the ascitic fluid using the Bonanno catheter. The average number of days of the abdominal drainage was 7.5days and the average volume of ascitic fluid drained from a patient per day was 2454.9 + 748mls. Eight (8) patients who had OHSS achieved clinical pregnancy (six intrauterine, one ectopic and one heterotopic pregnancies), giving a clinical pregnancy rate of 57.14% in patients with OHSS. Four patients had blocked Bonanno catheters and three of them had the catheter changed while the fourth had the catheter successfully flushed. Four patients had the insertion site dressing changed due to soaking with ascitic fluid. There was no incidence of injury to intra abdominal organs or broken catheter. Bonanno Catheter is both effective and safe in draining ascitic fluid following OHSS.

AIM: To present a dedicated series of transjugular intrahepatic porto-systemic shunts (TIPS) in the elderly since data is sparse on this population group. METHODS: A retrospective review was performed of patients at least 65 years of age who underwent TIPS at our institutions between 1997 and 2010. Twenty-five patients were referred for TIPS. We deemed that 2 patients were not considered appropriate candidates due to their markedly advanced liver disease. Of the 23 patients suitable for TIPS, the indications for TIPS placement was portal hypertension complicated by refractory ascites alone (n = 9), hepatic hydrothorax alone (n = 2), refractory ascites and hydrothorax (n = 1), gastrointestinal bleeding alone (n = 8), gastrointestinal bleeding and ascites (n = 3). RESULTS: Of these 23 attempted TIPS procedure patients, 21 patients had technically successful TIPS procedures. A total of 29 out of 32 TIPS procedures including revisions were successful in 21 patients with a mean age of 72.1 years (range 65-82 years). Three of the procedures were unsuccessful attempts at TIPS and 8 procedures were successful revisions of our existing TIPS. Sixteen of 21 patients who underwent successful TIPS (excluding 5 patients lost to follow-up) were followed for a mean of 14.7 mo. Ascites and/or hydrothorax was controlled following technically successful procedures in 12 of 13 patients. Bleeding was controlled following technically successful procedures in 10 out of 11 patients. CONCLUSION: We have demonstrated that TIPS is an effective procedure to control refractory complications of portal hypertension in elderly patients. PMID:22400084

Spontaneous bacterial peritonitis (SBP) requires rapid diagnosis and the initiation of antibiotics. Diagnosis of SBP is usually based on cytobacteriological examination of ascitic fluid. These tests require good laboratory facilities and reporting time of few hours to 1-2 day. However, the 24 h laboratory facilities not widely available in country like India. We evaluated the diagnostic utility of reagent strip (Multistix 10 SG(®)) for rapid diagnosis of SBP. The study was prospectively carried out on patients of cirrhosis with ascites. Bedside leukocyte esterase reagent strip testing was performed on ascitic fluid. Cell count as determined by colorimetric scale of reagent strip was compared with counting chamber method. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. Out of 100 patients with cirrhotic ascites, [72 males: 28 female; mean age 44.34 (SD 13.03) years] 18 patients were diagnosed to have SBP by counting chamber method as compared to 14 patients detected to have SBP by reagent strip test ≥++ positive. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of reagent strip ≥++ positive were 77.77%, 95.12%, 77.77%, 95.12% and 92% respectively compared to counting chamber method. Reagent strip to diagnose SBP is very specific but less sensitive as compared to counting chamber method. This can be performed rapidly, easily and efficiently even in remote area of developing countries. This bedside test could be a useful tool for the diagnosis of SBP in country like India.

This study examined the effects of dietary DL-2-hydroxy-4(methylthio)butanoic acid (DL-HMTBA) supplementation on growth performance, antioxidant capacity, and ascites syndrome (AS) in broilers reared at low ambient temperature (LAT) from 7 to 28 days of age. Eight hundred 7-day-old broilers were randomly assigned to two ambient temperatures (LAT and normal ambient temperature [NAT]), four supplemental DL-HMTBA levels (0.17, 0.34, 0.51, and 0.68 %) of the basal diet in a 2 × 4 factorial arrangement (ten replicate pens; ten birds/pen). LAT and NAT indicate temperatures of 12-14 and 24-26 °C in two chambers, respectively, and broilers were reared at these temperatures from 7 to 28 days of age. LAT significantly decreased body weight gain ( P < 0.001), serum glutathione (GSH) content (day 14, P = 0.02; day 28, P = 0.045), glutathione peroxidase (GSH-Px) activity, and total antioxidant capacity (T-AOC) at 21 days ( P = 0.001, 0.015) and 28 days ( P = 0.017, 0.010) and increased feed conversion ratio (FCR) ( P < 0.001), serum malondialdehyde (day 21, P = 0.000) and protein carbonyl Level (day 14, P = 0.003; day 21, P = 0.035). As for incidence of AS, there were significant effects of LAT on red blood cell (RBC) count ( P < 0.05), hematocrit (HCT) ( P < 0.05), and the right to total ventricular weight ratio (RV/TV) at 21 days ( P = 0.012) and 28 days ( P = 0.046). Supplementation of DL-HMTBA markedly decreased RV/TV at day 28 ( P = 0.021), RBC (day 21, P = 0.008), HCT (day 21, P < 0.001), mean cell hemoglobin (day 14, P = 0.035; day 21, P = 0.003), and serum protein carbonyl level (day 21, P = 0.009), while significantly increased serum GSH content (day 14, P = 0.022; day 28, P = 0.001), SOD and GSH-Px activities at 21 days of age ( P < 0.001 and P = 0.037). The optimal supplemental DL-HMTBA levels in basal diet of broilers aged from 7 to 28 days under low or normal temperatures were similar, so the authors recommended supplemental of DL-HMTBA level was 0.46 %.

Klein, Seth J., E-mail: kleins@mir.wustl.edu; Saad, Nael; Korenblat, Kevin

A 59-year old man with alcohol related cirrhosis and portal hypertension was referred for transjugular intrahepatic portosystemic shunt (TIPS) to treat his refractory ascites. Ten years later, two sequential TIPS revisions were performed for shunt stenosis and recurrent ascites. After these revisions, he returned with increased serum pancreatic enzyme levels and disseminated superficial fat necrosis; an iatrogenic pancreaticoportal vein fistula caused by disruption of the pancreatic duct was suspected. The bare area of the TIPS was subsequently lined with a covered stent-graft, and serum enzyme levels returned to baseline. In the interval follow-up period, the patient has clinically improved.

This mini review outlines studies of cell volume regulation in two closely related mammalian cell lines: nonadherent Ehrlich ascites tumour cells (EATC) and adherent Ehrlich Lettre ascites (ELA) cells. Focus is on the regulatory volume decrease (RVD) that occurs after cell swelling, the volume regulatory ion channels involved, and the mechanisms (cellular signalling pathways) that regulate these channels. Finally, I shall also briefly review current investigations in these two cell lines that focuses on how changes in cell volume can regulate cell functions such as cell migration, proliferation, and programmed cell death.

Recently, sirolimus, an inhibitor of mammalian target of rapamycin, was reported to decrease chylous effusion in patients with lymphangioleimyomatosis (LAM). We herein report a case of a 34-year-old woman with LAM who developed refractory chylothorax and chylous ascites during sirolimus therapy. In this case, to reduce chylous effusion, we administered octreotide, which is often used to control postoperative chylous effusion, in addition to the sirolimus therapy. This combination therapy reduced the chylothorax and chylous ascites. For patients with LAM, octreotide therapy in addition to sirolimus may be effective for treating sirolimus-refractory chylous effusion.

Ascites remains the most common cause of hospitalization among patients with decompensated cirrhosis. Paracentesis is a relatively safe procedure with low complication rates. Computerized tomography (CT)-guided therapeutic paracentesis could be a safe and effective alternative to unaided or aided (ultrasonogram-guided) bedside paracentesis. In this retrospective study, we aimed to compare the efficacy, safety, and cost-effectiveness of CT-guided paracentesis with bedside paracentesis. The period of study was from 2002 to 2012. All patients with cirrhosis who underwent therapeutic paracentesis were included in the study. These patients were divided into two groups. Group I consisted of patients who underwent CT-guided pigtail catheter insertion with ascitic fluid drainage. Group II consisted of patients who underwent beside therapeutic paracentesis after localization of fluid either by physical examination or sonographic localization. We measured the efficacy of CT-guided paracentesis and bedside paracentesis in terms of volume of fluid removed, length of stay, discharge doses of diuretics (spironolactone and furosemide) and number of days to readmission for symptomatic ascites. We also computed the cost-effectiveness of CT-guided therapeutic paracentesis when compared to a bedside procedure. Fischer exact test was used to analyze the distribution of categorical data and unpaired t -test was used for comparison of means. There were a total of 546 unique patients with diagnosed cirrhosis who were admitted to the hospital with symptomatic ascites and underwent therapeutic paracentesis. Two hundred and forty-seven patients underwent CT-guided paracentesis, while 272 patients underwent bedside paracentesis. There was significant inverse correlation between the amount of ascitic fluid removed and total length of stay in the hospital. We found that the volume of fluid removed via a CT-guided pigtail insertion and drainage (2.72 ± 2.02 L) is significantly higher when

In patients with fluid retention, the total plasma clearance of (51)Cr-EDTA (ClP) may overestimate the glomerular filtration rate (GFR). The present study was therefore undertaken in order to compare ClP with the urinary plasma clearance of (51)Cr-EDTA (ClU) in patients with cirrhosis with and without fluid retention. A total of 136 patients with cirrhosis (24 without fluid retention, 112 with ascites) received a quantitative intravenous injection of (51)Cr-EDTA followed by plasma and quantitative urinary samples for 5 hours. ClP was determined from the injected dose relative to the plasma concentration-time area, extrapolated to infinity. ClU was determined as urinary excretion relative to the plasma concentration-time area up to voiding. In patients without fluid retention, the difference between ClP and ClU (ClP - ClU = ClΔ) was mean 4.5 mL/min/1.73 m(2). In patients with ascites, ClΔ was significantly higher (17.6 mL/min/1.73 m(2), p < 0.0001). ClΔ increased with lower values of GFR (r = - 0.458, p < 0.001). Repeated measurements of ClU in a subgroup of patients with fluid retention (n = 25) gave almost identical values. Different types of corrections of one-pool clearance were almost identical with ClP, except for higher clearance values, which were somewhat underestimated by the former. In patients with fluid retention and ascites ClP and corrected one-pool clearance overestimates GFR substantially. Although ClU may underestimate GFR slightly, patients with ascites should collect urine quantitatively in order to obtain a reliable measurement of GFR.

An experiment was conducted to evaluate the effects of a periodically low eggshell temperature exposure during incubation and dietary supplementation of arginine on performance, ascites incidence, and cold tolerance acquisition in broilers. A total of 2,400 hatching eggs were randomly assigned to 2 treatment groups (16 replicates of 75 eggs per treatment). The eggs were incubated at a constant eggshell temperature (EST) of 37.8ºC throughout the incubation period (CON) or were periodically exposed to 15°C for one hour on days 11, 13, 15, and 17 of incubation and the EST was measured (periodical low EST; PLE). After hatching, 240 one-day-old male broiler chicks from both treatment groups were reared for 42 d with or without dietary arginine supplementation in a completely randomized design with a 2 × 2 factorial arrangement. In order to induce ascites, all chicks were exposed to a 15°C room temperature from 14 d onwards. Results showed that second grade chicks and yolk sac weight were decreased, and final body weight was increased in the PLE group. Ascites mortality rate was decreased only in the PLE group and dietary arginine supplementation had no apparent effect. In the PLE group, the packed cell volume (PCV) percentage and red blood cell (RBC) count were decreased. In conclusion, the results showed that the PLE treatment during incubation was associated with improved hatchability, chick quality, and productive performance of broilers and decreased ascites incidence during post hatch cold exposure. Dietary arginine supplementation had no beneficial effects in cold exposed broilers. © 2016 Poultry Science Association Inc.

Purpose CO2 leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasis after laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis between B-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). Materials and Methods Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC. Clinical efficacy was assessed from the objective remission rate (ORR), the Karnofsky Performance Status (KPS) score, and overall survival. The incidence of port-site metastasis was compared between the two groups. Results Patients in the B-ultrasound (n=32) and laparoscopy (n=30) groups were comparable in terms of age, sex, primary disease type, volume of ascites, and free cancer cell (FCC)-positive ascites. After HIPPC, there were no significant differences between the B-ultrasound and laparoscopy groups in the KPS score change, ORR, and median survival time. The incidence of port-site metastasis after HIPPC was not significantly different between the B-ultrasound (3 of 32, 9.36%) and laparoscopy (3 of 30, 10%) groups, but significantly different among pancreatic, gastric, ovarian, and colorectal cancer (33.33, 15.79, 10.00, and 0.00%, p<0.001). Conclusion The chimney effect may not be the key reason for port-site metastasis after laparoscopy. Other factors may play a role, including the local microenvironment at the trocar site and the delivery of viable FCCs (from the tumor or malignant ascites) to the trauma site during laparoscopic surgery.

Spontaneous bacterial peritonitis is an acute bacterial infection of ascitic fluid; it has a high incidence in cirrhotic patients and it is associated with high mortality. In such a situation, early diagnosis and treatment is crucial for the survival of the patient. However, bacterial analysis in ascitic fluid is currently based on culture methods, which are time-consuming and laborious. We report here the application of a photonic interferometer biosensor based on a bimodal waveguide (BiMW) for the rapid and label-free detection of bacteria directly in ascitic fluid. The device consists of a straight waveguide in which two modes of the same polarization interfere while interacting with the external medium through their evanescent fields. A bimolecular event occurring on the sensor area of the device (e.g. capturing bacteria) will differently affect each light mode, inducing a variation in the phase of the light exiting at the output of the waveguide. In this work, we demonstrate the quantitative detection of Bacillus cereus in buffer medium and Escherichia coli in undiluted ascitic fluid from cirrhotic patients. In the case of Bacillus cereus detection, the device was able to specifically detect bacteria at relevant concentrations in 12.5min and in the case of Escherichia coli detection, the analysis time was 25min. Extrapolation of the data demonstrated that the detection limits of the biosensor could reach few bacteria per milliliter. Based on the results obtained, we consider that the BiMW biosensor is positioned as a promising new clinical tool for user-friendly, cost-effective and real-time microbiological analysis.

The gold-standard for diagnosis is growth of Mycobacterium tuberculosis on ascitic fluid or peritoneal culture. Due to the non-specific signs and symptoms of disease, its early diagnosis is difficult, especially in patients with decompensated cirrhosis. The reported sensitivity of ascitic fluid is low and to obtain tissue for peritoneal biopsy in patients with cirrhosis is difficult. Endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) is a good alternative to obtain peritoneal tissue for establishing the diagnosis of peritoneal TB. To assess the role of EUS-FNA in the diagnosis of peritoneal tuberculosis in patients with decompensated cirrhosis. Consecutive patients with peritoneal thickening, ascites and decompensated cirrhosis underwent EUS-FNA from the thickened omentum. Presence of granuloma or demonstration of acid fast bacilli was diagnostic of peritoneal tuberculosis. A total of 5 patients with CLD underwent EUS-FNA from omentum. FNA cytology revealed granuloma with multinucleated cells in all patients (100%) and AFB stain was positive in 2 of them (40%). We hereby report the use of EUS guided fine needle aspiration (FNA) of peritoneum as a newer, safe and unexplored technique for diagnosis of peritoneal TB.

The purpose of this study was to investigate the prognostic value of various clinical, ECG, echocardiographic, and Doppler echocardiographic variables in dogs with dilated cardiomyopathy. The relationship to survival of 11 variables was evaluated in 63 dogs. Studied variables were age at time of diagnosis, class of heart failure (HF), dyspnea, ascites, atrial fibrillation (AF), ejection fraction (EF), E-point septal separation, end-diastolic volume index, end-systolic volume index (ESV-I), and restrictive or nonrestrictive transmitral flow (TMF) pattern. Median survival time was 671 days (lower 95% confidence limit, 350 days). Survival curves showed that severity of HF, ascites, ESV-I greater than 140 mL/m2, EF less than 25%, and restrictive TMF pattern had a significant negative relation to survival time. Thirty-nine dogs with both sinus rhythm and AF presented adequate TMF recordings; in these dogs, after stratification by TMF pattern, the restrictive TMF pattern was the most important negative prognostic indicator. We conclude that in dogs with dilated cardiomyopathy the restrictive TMF pattern appears to represent a useful prognostic indicator. Class of HF, ascites, ESV-I, and EF are also useful indexes if an adequate TMF pattern is not recorded.

Demons-Meigs syndrome is a benign tumor of the ovary. It is very rare and its physiopathology remains obscure. We report a case of Demons-Meigs syndrome in a woman aged 51 years. It was discovered following a right pleural effusion syndrome with ascites and an abdominopelvic mass. Rate of serum CA 125 was 412IU/mL. Surgical exploration revealed ascites of one litre with no suspicious peritoneal lesion and an ovarian fibrothecoma of 70 mm. There were no post-operative complications and three months later, the level of CA 125 was negative with a total drainage of effusions. Copyright © 2011. Published by Elsevier Masson SAS.

Paraneoplastic syndromes are generally defined as clinical disorders associated with malignant diseases, and hypocalcemia associated with cancer is a rare condition. A woman in her 60s was referred to our hospital for the further examination of massive ascites due to carcinoma of unknown primary origin. She complained of numbness around her lips, and marked hypocalcemia of 5.0 mg/dL was noted. After two courses of chemotherapy, computed tomography showed a decrease in the ascites, and her serum calcium level increased. Although hypocalcemia is a very rare condition in patients with gastric cancer, serum calcium values should be evaluated when neurological symptoms are observed.

Eight hundred 7-day-old broilers were randomly assigned to two ambient temperatures (LAT and normal ambient temperature [NAT]), four supplemental DL-HMTBA levels (0.17, 0.34, 0.51, and 0.68 %) of the basal diet in a 2 × 4 factorial arrangement (ten replicate pens; ten birds/pen). LAT and NAT indicate temperatures of 12-14 and 24-26 °C in two chambers, respectively, and broilers were reared at these temperatures from 7 to 28 days of age. LAT significantly decreased body weight gain (P < 0.001), serum glutathione (GSH) content (day 14, P = 0.02; day 28, P = 0.045), glutathione peroxidase (GSH-Px) activity, and total antioxidant capacity (T-AOC) at 21 days (P = 0.001, 0.015) and 28 days (P = 0.017, 0.010) and increased feed conversion ratio (FCR) (P < 0.001), serum malondialdehyde (day 21, P = 0.000) and protein carbonyl Level (day 14, P = 0.003; day 21, P = 0.035).

International guidelines for antibiotic treatment of spontaneous bacterial peritonitis (SBP) are based on studies conducted decades ago and do not reflect regional differences of bacterial epidemiology. We retrospectively analyzed epidemiology of agents, antibiotic resistance patterns, and survival in liver cirrhosis patients with their first episode of SBP during the years 2007-2013. Of the 311 patients included, 114 patients had a positive ascites culture, and 197 had an ascitic neutrophil count >250 μL. Gram-positive bacteria (47.8%) were more frequently found than Gram-negatives (44.9%), fungi in 7.2%. Enterobacter spp. (40.6%), Enterococcus spp. (26.1%), and Staphylcoccus spp. (13.8%) were the most frequently isolated agents. Third-generation cephalosporins covered 70.2% of non-nosocomial and 56.3% of nosocomial-acquired SBP cases.When SBP was diagnosed by a positive ascitic culture, survival was highly significantly reduced (mean: 13.9 ± 2.9 months; 95% confidence interval [CI]: 8.1-19.8) compared with culture-negative SBP patients (mean: 44.1 ± 5.4 months; 95% CI: 33.4-54.9; P = 0.000). Along with model of end-stage liver disease score and intensive care unit contact, a positive ascites culture remained an independent risk factor associated with poor survival (odds ratio: 1.49; 95% CI: 1.09-2.03) in multivariate analysis; piperacillin/tazobactam proved to be an adequate antibiotic for nosocomial and non-nosocomial SBP in 85.1% and 92.5%, respectively. SBP infection with Enterococcus spp. was associated with poor patient survival (P = 0.048). Third-generation cephalosporins have poor microbial coverage for treatment of SBP. Current guidelines need to adapt for the emerging number of Gram-positive infectious agents in SBP patients. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Purpose The present study aimed to investigate the role of hepatic venous pressure gradient (HVPG) for prediction of long-term mortality in patients with decompensated cirrhosis. Materials and Methods Clinical data from 97 non-critically-ill cirrhotic patients with HVPG measurements were retrospectively and consecutively collected between 2009 and 2012. Patients were classified according to clinical stages and presence of ascites. The prognostic accuracy of HVPG for death, survival curves, and hazard ratios were analyzed. Results During a median follow-up of 24 (interquartile range, 13-36) months, 22 patients (22.7%) died. The area under the receiver operating characteristics curves of HVPG for predicting 1-year, 2-year, and overall mortality were 0.801, 0.737, and 0.687, respectively (all p<0.01). The best cut-off value of HVPG for predicting long-term overall mortality in all patients was 17 mm Hg. The mortality rates at 1 and 2 years were 8.9% and 19.2%, respectively: 1.9% and 11.9% with HVPG ≤17 mm Hg and 16.2% and 29.4% with HVPG >17 mm Hg, respectively (p=0.015). In the ascites group, the mortality rates at 1 and 2 years were 3.9% and 17.6% with HVPG ≤17 mm Hg and 17.5% and 35.2% with HVPG >17 mm Hg, respectively (p=0.044). Regarding the risk factors for mortality, both HVPG and model for end-stage liver disease were positively related with long-term mortality in all patients. Particularly, for the patients with ascites, both prothrombin time and HVPG were independent risk factors for predicting poor outcomes. Conclusion HVPG is useful for predicting the long-term mortality in patients with decompensated cirrhosis, especially in the presence of ascites. PMID:26632394

In vitro studies suggest that ovarian cancer evades immune rejection by fostering an immunosuppressive environment within the peritoneum; however, the functional responses of ovarian cancer-specific T cells have not been directly investigated in vivo. Therefore, we developed a new murine model to enable tracking of tumor-specific CD8(+) T-cell responses to advanced ovarian tumors. The ovarian tumor cell line ID8 was transfected to stably express an epitope-tagged version of HER-2/neu (designated Neu(OT-I/OT-II)). After i.p. injection into C57BL/6 mice, ID8 cells expressing Neu(OT-I/OT-II) gave rise to disseminated serous adenocarcinomas with extensive ascites. CD8(+) T cells expressing a transgenic T-cell receptor specific for the OT-I epitope of Neu(OT-I/OT-II) were adoptively transferred into tumor-bearing mice, and functional responses were monitored. Cytokine signaling requirements were evaluated by comparing the responses of wild-type donor T cells with those with genetic deletion of the interleukin (IL)-2/IL-15 receptor beta subunit (CD122) or the IL-2 receptor alpha subunit (CD25). On adoptive transfer into tumor-bearing hosts, wild-type OT-I T cells underwent a striking proliferative response, reaching peak densities of approximately 40% and approximately 90% of CD8(+) T cells in peripheral blood and ascites, respectively. OT-I cells infiltrated and destroyed tumor tissue, and ascites completely resolved within 10 days. By contrast, CD122(-/-) OT-I cells and CD25(-/-) OT-I cells proliferated in blood but failed to accumulate in ascites or tumor tissue or induce tumor regression. Contrary to expectation, advanced ovarian cancers can support extraordinary CD8(+) T-cell proliferation and antitumor activity through an IL-2/IL-15-dependent mechanism.

Peritoneal metastasis (PM) is a poor prognostic factor in patients with gastric cancer. The aim of this study was to evaluate the efficacy and safety of hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with advanced gastric cancer with PM by retrospective analysis. A total of 54 gastric cancer patients with positive ascitic fluid cytology were included in this study: 23 patients were treated with systemic chemotherapy combined with HIPEC (HIPEC+ group) and 31 received systemic chemotherapy alone (HIPEC- group). The patients were divided into 4 categories according to the changes of ascites, namely disappear, decrease, stable and increase. The disappear + decrease rate in the HIPEC+ group was 82.60%, which was statistically significantly superior to that of the HIPEC- group (54.80%). The disappear + decrease + stable rate was 95.70% in the HIPEC+ group and 74.20% in the HIPEC- group, but the difference was not statistically significant. In 33 patients with complete survival data, including 12 from the HIPEC+ and 21 from the HIPEC- group, the median progression-free survival was 164 and 129 days, respectively, and the median overall survival (OS) was 494 and 223 days, respectively. In patients with ascites disappear/decrease/stable, the OS appeared to be better compared with that in patients with ascites increase, but the difference was not statistically significant. Further analysis revealed that patients with controlled disease (complete response + partial response + stable disease) may have a better OS compared with patients with progressive disease, with a statistically significant difference. The toxicities were well tolerated in both groups. Therefore, HIPEC was found to improve survival in advanced gastric cancer patients with PM, but the difference was not statistically significant, which may be attributed to the small number of cases. Further studies with larger samples are required to confirm our data. PMID:27446587

The availability of adequate cancer stem cells or cancer stem-like cell (CSC) is important in cancer study. From ovarian cancer cell lines, SKOV3 and OVCAR3, we induced peritoneal ascites tumors in immunodeficient mice. Among the cells (SKOV3.PX1 and OVCAR3.PX1) from those tumors, we sorted both CD44 and CD133 positive cells (SKOV3.PX1_133+44+, OVCAR3.PX1_133+44+), which manifest the characteristics of self-renewal, multi-lineage differentiation, chemoresistance and tumorigenicity, those of cancer stem-like cells (CSLC). Intraperitoneal transplantation of these CD44 and CD133 positive cells resulted in poorer survival in the engrafted animals. Clinically, increased CD133 expression was found in moderately and poorly differentiated (grade II and III) ovarian serous cystadenocarcinomas. The ascites tumor cells from human ovarian cancers demonstrated more CD133 and CD44 expressions than those from primary ovarian or metastatic tumors and confer tumorigenicity in immunodeficient mice. Compared to their parental cells, the SKOV3.PX1_133+44+ and OVCAR3.PX1_133+44+ cells uniquely expressed 5 CD markers (CD97, CD104, CD107a, CD121a, and CD125). Among these markers, CD97, CD104, CD107a, and CD121a are significantly more expressed in the CD133+ and CD44+ double positive cells of human ovarian ascites tumor cells (Ascites_133+44+) than those from primary ovarian or metastatic tumors. The cancer stem-like cells were enriched from 3% to more than 70% after this manipulation. This intraperitoneal enrichment of cancer stem-like cells, from ovarian cancer cell lines or primary ovarian tumor, potentially provides an adequate amount of ovarian cancer stem-like cells for the ovarian cancer study and possibly benefits cancer therapy.

Various studies have investigated hepatic carcinoma cachexia, however, there is little published information regarding the effect of Chinese Medicine carcinoma cachexia. The present study was performed to investigate the effect of modified Chinese herbal compound jianpijiedu (MJPJD) on a mouse model of ascites‑induced hepatic carcinoma cachexia. C57BL/6 mice were randomized to five groups: Control (Group A); xenograft tumor (Group B); low concentration of MJPJD (Group C); high concentration of MJPJD (Group D) and medroxyprogesterone (MPA) combined with indometacin (IND; Group E). The mouse model of ascites‑induced hepatic carcinoma cachexia was established by abdominal injection of H22 hepatic carcinoma cells. Subsequently, the body weight, food intake and gastrocnemius weight were recorded, and the levels of interleukin (IL)‑lα, IL‑6, tumor necrosis factor‑α (TNF‑α) in ascites were detected by enzyme‑linked immunosorbent assay. The protein expression levels of muscle RING‑finger protein‑1 (MU‑RF1) and atrogin 1 were detected by western blotting and immunohistochemistry, and the mRNA levels in gastrocnemius were detected by reverse transcription‑quantitative polymerase chain reaction. Compared with the xenograft tumor group, the administration of MJPJD inhibited the increase in body weight and the volume of ascites, the consumption of gastrocnemius was reduced, the net weight of ascites was maintained, the food intake was enhanced and the levels of the cytokines IL‑lα, IL‑6, TNF‑α in ascites and the levels of MU‑RF1 and atrogin 1 proteins were reduced. These results indicated that MJPJD delays the pathological process of ascites‑induced hepatic carcinoma cachexia, and the mechanism of action may be correlated with a reduction in the levels of IL‑lα, IL‑6, TNF‑α and inhibiting the activation of the ubiquitin proteosome pathway.

The roots of Pfaffia paniculata (Brazilian ginseng) have been indicated for the treatment of several diseases and as an analgesic and antiinflamatory drug. Treatment of mice with 200 mg/kg of the powdered root of P. paniculata reduced the Ehrlich ascitic volume [Matsuzaki, P., Akisue, G., Salgado Oloris, S.C., Gorniak, S.L., Zaidan Dagli, M.L., 2003. Effect of Pffafia paniculata (Brazilian ginseng) on the Ehrlich tumor on its ascitic form. Life Sciences, Dec 19; 74 (5), 573-579.]. One of the putative means to control the Ehrlich tumor growth is by increasing macrophage activity [Kleeb, S.R., Xavier, J.G., Frussa-Filho, R., Dagli, M.L.Z., 1997. Effect of haloperidol on the development of the solid Ehrlich tumor in mice. Life Sciences, 60 (4/5), 69-742.]. The aim of this study was to investigate experimentally the effects of the methanolic extract of P. paniculata roots on macrophage activity. Male mice received, by gavage, once a day, different doses (100, 250, or 500 mg/kg) of the methanolic extract of P. paniculata or filtered water, as control, for 10 days. Macrophage activity was evaluated through the phagocytosis index (PI), spreading index (SI), production of peroxide oxigen and nitric oxide. The peritoneal cells were activated with ip inoculation of Ehrlich ascitic cells, 24 h before the macrophage harvesting. The methanolic extract raised significantly the SI of mice from group of 500 mg/kg in comparison with the control group and group of 100 mg/kg. This raise of SI possibly induced the higher phagocytic activity observed in the experimental situation. Increased macrophage activity may be one of the effects contributing to inhibition of the Ehrlich ascitic tumor growth in mice.

Patients with cirrhosis and ascites are prone to abdominal wall complications largely predominate by umbilical hernia. Elective surgery is indicated in select patients but a high morbidity and mortality rate occurs if it is performed in emergency conditions. We present a clinical case of a patient with advanced alcoholic liver disease who came to the emergency room for an acutely incarcerated umbilical hernia. Due to the high surgical risk, we had to discuss other treatment options. The use of umbilical paracentesis for incarcerated hernia reduction in cirrhotic patients with tense ascites is a safe and reproducible technique. Umbilical paracentesis could be considered as an alternative to emergency surgery in these high-risk patients.

The distinction between exudates and transudates is very important in the patient management. Here we evaluate whether the acute-phase protein serum amyloid A (SAA), in comparison with C reactive protein (CRP) and total protein (TP), can be useful in this discrimination. CRP, SAA, and TP were determined in 36 exudate samples (27 pleural and 9 ascitic) and in 12 transudates (9 pleural and 3 ascitic). CRP, SAA, and TP were measured. SAA present in the exudate corresponded to 10% of the amount found in serum, that is, the exudate/serum ratio (E/S) was 0.10 +/- 0.13. For comparison, the exudate/serum ratio for CRP and TP was 0.39 +/- 0.37 and 0.68 +/- 0.15, respectively. There was a strong positive correlation between serum and exudate SAA concentration (r = 0.764; p < 0.0001). The concentration of SAA in transudates was low and did not overlap with that found in exudates (0.02-0.21 versus 0.8-360.5 g/mL). SAA in pleural and ascitic exudates results mainly from leakage of the serum protein via the inflamed membrane. A comparison of the E/S ratio of SAA and CRP points SAA as a very good marker in discriminating between exudates and transudates.

High-grade serous ovarian cancer (HGSOC) is the most aggressive type of ovarian cancer and is responsible for most deaths caused by gynecological cancers. Numerous candidate biomarkers were identified for this disease in the last decades, but most were not sensitive or specific enough for clinical applications. Hence, new biomarkers for HGSOC are urgently required. This study aimed to identify new markers by isolating different extracellular vesicle (EV) types from the ascites of ovarian cancer patients according to their affinities for lipid-binding proteins and analyzing their protein cargo. This approach circumvents the low signal-to-noise ratio when using biological fluids for biomarker discovery and the issue of contamination by large non-EV complexes. We isolated and analyzed three distinct EV populations from the ascites of patients with ovarian cancer or cirrhosis and observed that Annexin V-binding EVs have higher levels of matrix metalloproteinase 9 in malignant compared to portal-hypertensive ascites. As this protein was not detected in other EV populations, this study validates our approach of using different EV types for optimal biomarker discovery. Furthermore, MMP9 in Annexin V-binding EVs could be a HGSOC biomarker with enhanced specificity, because its identification requires detection of two distinct components, that is, lipid and protein.

Ascites and hyponatremia are the most common complications in patients with liver cirrhosis and develop as a consequence of a severe impairment of liver function and portal hypertension. Increasing evidences support the central role of renal function alterations in the pathogenesis of hydroelectrolytic imbalances in cirrhotic patients, thus implying a dense cross-talk between liver and kidney in the systemic and splanchnic vascular homeostasis in such subjects. Since Arginin Vasopressin (AVP) hyperincretion occurs at late stage of cirrhosis and plays an important role in the development of refractory ascites, dilutional hyponatremia and finally hepato-renal syndrome, selective antagonists of AVP receptors V2 (vaptans) have been recently introduced in the therapeutic algorithm of advanced cirrhotic patients. Despite the promising results of earlier phase-two studies, randomized controlled trials failed to find significant results in terms of efficacy of such drugs both in refractory ascites and hyponatremia. Moreover, concerns on their safety profile arise, due to the number of potentially severe side effects of vaptans in the clinical setting, such as hypernatremia, dehydration, renal impairment, and osmotic demyelination syndrome. More robust data from randomized controlled trials are needed in order to confirm the potential role of vaptans in the management of advanced cirrhotic patients. PMID:25429317

Purpose: Monoclonal antibodies or specific antibodies are now an essential tool of biomedical research and are of great commercial and medical value. The purpose of this study was to produce large scale of monoclonal antibody against CD34 in order to diagnostic application in leukemia and purification of human hematopoietic stem/progenitor cells. Methods: For large scale production of monoclonal antibody, hybridoma cells that produce monoclonal antibody against human CD34 were injected into the peritoneum of the Balb/c mice which have previously been primed with 0.5 ml Pristane. 5 ml ascitic fluid was harvested from each mouse in two times. Evaluation of mAb titration was assessed by ELISA method. The ascitic fluid was examined for class and subclasses by ELISA mouse mAb isotyping Kit. mAb was purified from ascitic fluid by affinity chromatography on Protein A-Sepharose. Purity of monoclonal antibody was monitored by SDS -PAGE and the purified monoclonal antibody was conjugated with FITC. Results: Monoclonal antibodies with high specificity and sensitivity against human CD34 by hybridoma technology were prepared. The subclass of antibody was IgG1 and its light chain was kappa. Conclusion: The conjugated monoclonal antibody could be a useful tool for isolation, purification and characterization of human hematopoietic stem cells. PMID:24312838

Transjugular intrahepatic portosystemic shunting (TIPS) is an effective treatment modality for refractory variceal bleeding and ascites in patients with cirrhotic portal hypertension (CPH). Variceal rebleeding and shunt dysfunction are major post-TIPS morbidities. This study aimed to retrospectively evaluate the effectiveness and safety of use of concomitant variceal embolization and prophylactic antiplatelet/anticoagulative in patients with CPH undergoing TIPS. Between October 2006 and October 2011, 182 patients with CPH were retrospectively and consecutively hospitalized for elective TIPS with Fluency stenting. Concomitant variceal embolization was given after establishing the shunt. Subcutaneous heparin was given after TIPS and replaced by oral clopidogrel, aspirin, or warfarin for at least 6 months. Main outcome measures included shunt patency rate, recurrence of CPH (rebleeding and/or refractory ascites), hepatic encephalopathy (HE) frequency, and post-TIPS survival. The cumulative primary patency rate was 96%, 94%, 90%, 88%, and 88% at 6, 12, 24, 36, and 48 months, respectively. Shunt stenosis occurred in 16 (9%) patients, gastrointestinal (GI) rebleeding in 32 (17.5%) patients, recurrence of refractory ascites 44 (48%) patients, HE in 42 (23%) patients, and death in 36 (20%) patients during the follow-up period. Use of concomitant variceal embolization and prophylactic antiplatelet/anticoagulative was associated with a favorable shunt patency and a low risk of GI rebleeding.

Methylglyoxal-bis(guanylhydrazone), Methyl-G, is a potent antineoplastic agent currently undergoing Phase l clinical trials. Serum, ascitic and pleural fluids, and urine are deproteinized with methanol, supernatant is evaporated, residue is redissolved in the eluent, lipids are removed with carbon tetrachloride, and an aliquot of the aqueous layer injected into the chromatograph. Ethylglyoxal-bis(guanylhydrazone) (Ethyl-G) is the internal standard. The mobile phase is a mixture of an aqueous buffer (containing 0.004 M heptane and pentane sulfonic acid, 90%:10%, buffered to pH 3.5) and methanol (68%:32%). The ion-pair complex is retained on a micro Bondapak C18 column, eluted with a flow of 2.0 mL/min. Absorbance is measured at 280 nm. Detectability: 30 ng/mL (0.11 micro M) in serum, ascitic and pleural fluids, 300 ng/mL (1.1 micro M) in urine. Calibration curves (peak height ratios of Methyl-G/Ethyl-G plotted against known drug concentrations) were linear in the 0.1-30 microg/mL range. Correlation coefficinets were 0.999; coefficients of variation for reproducibility were less than 5%. Residual blood levels of Methyl-G persist for several days. Methyl-G was found to pass into ascitic fluid.

Purpose. To understand systemic the influence of stent therapy for inferior vena cava (IVC) obstruction due to advanced liver tumor. Methods. Seven patients with symptomatic IVC obstruction due to advanced primary (n 4) or secondary (n = 3) liver tumor were subjected to stent therapy. Enrollment criteria included high IVC pressure over 15 mmHg and the presence of edema and ascites. Z-stents were deployed using coaxial sheath technique via femoral venous puncture. Physiologic and hematobiochemical parameters were analyzed. Results. All procedures were successful, and the stents remained patent until patient death. Promptly after stent placement, the IVC flow recovered, andmore » the venous blood pressure in the IVC below the obstruction level showed a significant decrease from 20.8 {+-} 1.2 mmHg (mean {+-} SE) to 10.7 {+-} 0.7 mmHg (p < 0.01). Transient mild increase of right atrial pressure was observed in 1 patient. During the following week prominent diuresis was observed in all patients. Mean urine output volume in the 3 days before the stent therapy was 0.81 {+-} 0.09 l/day compared with 2.1 {+-} 0.2 l/day (p < 0.01) in the 3 days after. The edema and ascites decreased in all patients. The caval pressure change correlated well (r > 0.6) with the urine volume increase, and with the decreased volume of edema and ascites. The urine volume increase correlated well with the decrement of edema, but not with that of ascites. Improvements for various durations in the levels of blood urea nitrogen, serum creatinine, lactate dehydrogenase, fibrinogen, and platelet count were found (p < 0.05). These hematobiochemical changes were well correlated with each other and with the decrement of ascites. Two patients showed a low blood sodium level of 128.5 mEq/l after intensive natriuresis, and one of them died on day 21 with hepatic failure, which was interpreted as maladaptation aggravation. The mean survival time was 94.1 {+-} 34.1 days (mean {+-} SD), ranging from 21 to 140

POEMS (acronym for polyneuropathy, organomegaly, endocrinopathy, M protein myeloma and skin changes), is a rare disease which occurs in the setting of plasma cell dyscrasias. We describe a case of an adult lady who presented with gradual onset weakness of all four limbs and multisystem involvement characterized by pedal edema, ascites, hyperpigmentation and hypogonadism. Nerve conduction study showed severe sensorimotor polyneuropathy. Serum immunofixation showed lambda light chain restricted monoclonal gammopathy. Bone marrow biopsy consistent with plasma cell dyscrasia. Hormonal assay showed decreased FSH, LH and estradiol levels which led us to diagnosis of hypogonadotrophic hypogonadism. The patient responded well to combination therapy of thalidomide, melphalan and dexamethasone. Eight months after the therapy, she noted decreased paresthesias and increased strength. She had reduced edema and ascites.

Climate change impact assessment and adaptation research in agriculture has focused primarily on crop production, with less known about the potential impacts on livestock. We investigated how the prevalence of health and welfare conditions in broiler (meat) chickens changes with weather (temperature, rainfall, air frost) in a temperate climate. Cases of 16 conditions were recorded at approved slaughterhouses in Great Britain. National prevalence rates and distribution mapping were based on data from more than 2.4 billion individuals, collected between January 2011 and December 2013. Analysis of temporal distribution and associations with national weather were based on monthly data from more than 6.8 billion individuals, collected between January 2003 and December 2013. Ascites, bruising/fractures, hepatitis and abnormal colour/fever were most common, at annual average rates of 29.95, 28.00, 23.76 and 22.29 per 10 000, respectively. Ascites and abnormal colour/fever demonstrated clear annual cycles, with higher rates in winter than in summer. Ascites prevalence correlated strongly with maximum temperature at 0 and -1 month lags. Abnormal colour/fever correlated strongly with temperature at 0 lag. Maximum temperatures of approximately 8°C and approximately 19°C marked the turning points of curve in a U-shaped relationship with mortality during transportation and lairage. Future climate change research on broilers should focus on preslaughter mortality.

Patient: Female, 54 Final Diagnosis: Suprahepatic inferior vena cava anastomosis stricture Symptoms: Ascites • fatigue • lower limb edema • hepatomegaly Medication: — Clinical Procedure: — Specialty: Transplantology • Critical Care Medicine Objective: Unusual clinical course Background: Suprahepatic inferior vena cava anastomosis stricture is an unusual vascular complication after orthotopic liver transplantation with the “piggyback” technique. Clinical manifestations are dependent upon the severity of the stenosis. Portopulmonary hypertension after orthotopic liver transplantation is a complication that carries high mortality due to cardiopulmonary dysfunction. The pathogenesis of pulmonary vascular disorders after orthotopic liver transplantation remains uncertain. Case Report: We report a case of acute right heart pressure overload after surgical correction of the suprahepatic inferior vena cava anastomotic stricture in a 54-year-old woman who had preexisting pulmonary arterial hypertension associated with portal hypertension after orthotopic liver transplantation. Twenty months posttransplantation, she developed fatigue and progressive ascites. On admission, the patient had hepatomegaly, ascites, and lower limb edema. Symptoms in the patient developed gradually over time. Conclusions: Recurrent portal hypertension by vascular complications is a cause of pulmonary arterial hypertension after orthotopic liver transplantation. Clinical manifestations of suprahepatic inferior vena cava anastomotic stenosis are dependent upon their severity. Sildenafil is an effective drug for treatment of pulmonary arterial hyper-tension after portal hypertension by vascular complications. PMID:24046802

Estimation of body cell mass (BCM) has been regarded valuable for the assessment of malnutrition. To investigate the value of segmental bioelectrical impedance analysis (BIA) for BCM estimation in malnourished subjects and acromegaly. Nineteen controls and 63 patients with either reduced (liver cirrhosis without and with ascites, Cushing's disease) or increased BCM (acromegaly) were included. Whole-body and segmental BIA (separately measuring arm, trunk, leg) at 50 kHz was compared with BCM measured by total-body potassium. Multiple regression analysis was used to develop specific equations for BCM in each subgroup. Compared to whole-body BIA equations, the inclusion of arm resistance improved the specific equation in cirrhotic patients without ascites and in Cushing's disease resulting in excellent prediction of BCM (R(2) = 0.93 and 0.92, respectively; both P<0.001). In acromegaly, inclusion of resistance and reactance of the trunk best described BCM (R(2) = 0.94, P<0.001). In controls and in cirrhotic patients with ascites, segmental impedance parameters did not improve BCM prediction (best values obtained by whole-body measurements: R(2)=0.88 and 0.60; P<0.001 and <0.003, respectively). Segmental BIA improves the assessment of BCM in malnourished patients and acromegaly, but not in patients with severe fluid overload. Copyright 2003 Elsevier Science Ltd.

Lupus erythematosus cell phenomenon in synovial and peritoneal fluids in systemic lupus erythematosus: smoking guns, crime scenes and a twist.

The presence of the lupus erythematosus (LE) phenomenon has been generally conceptualized as an in vitro occurrence where numerous damaged cells are present and substantial nucleo-phagocytosis has occurred. In systemic lupus erythematosus (SLE), the positive LE cell phenomenon has been shown to indicate active disease with major organ involvement which potentially warrants prompt and heavy immunosuppressive therapy. We report a 36-year-old woman with a known history of SLE who presented with fever, left knee effusion, polyserositis, pancytopenia, low complement and high anti-dsDNA antibody levels whose immunosuppressive treatment was escalated in view of the clinically and serologically active SLE, accompanied by the presence of LE cells in her inflammatory yet sterile left knee synovial fluid. Within 3 days of immunosuppressant escalation, her ascites worsened. While microscopic examination of the ascitic fluid also revealed LE cells, culture of the ascitic fluid later grew Candida parapsilosis. The patient subsequently responded to the addition of anti-fungal therapy into her augmented immunosuppressive regime. Coexistence of the LE cell phenomenon and infection in SLE patients has hitherto not been described. This case illustrates that infection remains to be meticulously excluded despite the presence of the LE phenomenon in the context of clinically and serologically active SLE. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

2015-01-01

Cancer is a leading cause of death worldwide. Due to the toxic side effects of the commonly used chemotherapeutic drug cyclophosphamide (CTX), the use of herbal medicines with fewer side effects but having potential use as inducing anti-cancer outcomes in situ has become increasingly popular. The present study sought to investigate the effects of a methanolic extract of Bauhinia tomentosa against Dalton's ascites lymphoma (DAL) induced ascites as well as solid tumors in BALB/c mice. Specifically, B. tomentosa extract was administered intraperitonealy (IP) at 10 mg/kg. BW body weight starting just after tumor cell implantation and thereafter for 10 consecutive days. In the ascites tumor model hosts, administration of extract resulted in a 52% increase in the life span. In solid tumor models, co-administration of extract and CTX significantly reduced tumor volume (relative to in untreated hosts) by 73% compared to just by 52% when the extract alone was provided. Co-administration of the extract also mitigated CTX-induced toxicity, including decreases in WBC count, and in bone marrow cellularity and α-esterase activity. Extract treatment also attenuated any increases in serum levels of TNFα, iNOS, IL-1β, IL-6, GM-CSF, and VEGF seen in tumor-bearing hosts. This study confirmed that, the potent antitumor activity of B.tomentosa extract may be associated with immune modulatory effects by regulating anti-oxidants and cytokine levels.

Solitomab is a novel, bispecific, single-chain antibody that targets epithelial cell adhesion molecule (EpCAM) on tumor cells and also contains a cluster of differentiation 3 (CD3) (T-cell coreceptor) binding region. The authors evaluated the in vitro activity of solitomab against primary chemotherapy-resistant epithelial ovarian carcinoma cell lines as well as malignant cells in ascites. EpCAM expression was evaluated by flow cytometry in 5 primary ovarian cancer cell lines and in 42 fresh ovarian tumor cell cultures in ascites from patients with mainly advanced or recurrent, chemotherapy-resistant disease. The potential activity of solitomab against EpCAM-positive tumor cells was evaluated by flow cytometry, proliferation, and 4-hour chromium-release, cell-mediated cytotoxicity assays. EpCAM expression was detected by flow cytometry in approximately 80% of the fresh ovarian tumors and primary ovarian tumor cell lines tested. EpCAM-positive, chemotherapy-resistant cell lines were identified as resistant to natural killer cell-mediated or T-cell-mediated killing after exposure to peripheral blood lymphocytes in 4-hour chromium-release assays (mean±standard error of the mean, 3.6%±0.7% of cells killed after incubation of EpCAM-positive cell lines with control bispecific antibody). In contrast, after incubation with solitomab, EpCAM-positive, chemotherapy-resistant cells became highly sensitive to T-cell cytotoxicity (mean±standard error of the mean, 28.2%±2.05% of cells killed; P<.0001) after exposure to peripheral blood lymphocytes. Ex vivo incubation of autologous tumor-associated lymphocytes with EpCAM-expressing malignant cells in ascites with solitomab resulted in a significant increase in T-cell activation markers and a reduction in the number of viable ovarian tumor cells in ascites (P<.001). Solitomab may represent a novel, potentially effective agent for the treatment of chemotherapy-resistant ovarian cancers that overexpress EpCAM. © 2014 American

Differentiation by colchicine and vincristine sulphate of regenerative hepatocellular mitosis and tumour-associated hepatocellular mitosis.

PubMed

Parry, E W

1977-10-01

Colchicine and vincristine sulphate differentiate sharply between hepatocyte mitosis associated with the Ehrlich ascites tumour, and regenerative (post-CCl4 necrosis) hepatocyte mitosis. In the former case there is a gross depression of prophase index and a marked lowering of the overall mitotic index. In the latter, although a degree of prophase depression is evident, this is insufficient to prevent an overall substantial elevation of mitotic index due to accumulation at metaphase. Very low doses of colchicine claimed to be effective in stathmokinesis of hepatocytes under influence of hepatomitogenic tumour brei and tumour extracts, produced no discernible effect on the mitotic pattern of hepatocytes in Ehrlich ascites tumour-bearing mice nor in post-CCl4 regenerating livers. The results are discussed in the context of known features of tumour-associated hepatocellular mitosis.

Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of primary effusion lymphomas (PEL). PEL cell lines infected with KSHV, but negative for Epstein-Barr virus have a tumorigenic potential in non-obese diabetic/severe combined immunodeficient mice and result in efficient engraftment and formation of malignant ascites with notable abdominal distension, consistent with the clinical manifestations of PEL in humans. Using this preclinical mouse model, we demonstrate that the combination of arsenic trioxide and interferon-alpha (IFN) inhibits proliferation, induces apoptosis and downregulates the latent viral transcripts LANA-1, v-FLIP and v-Cyc in PEL cells derived from malignant ascites. Furthermore, this combination decreases the peritoneal volume and synergistically increases survival of PEL mice. These results provide a promising rationale for the therapeutic use of arsenic/IFN in PEL patients.

Development of differential cytotoxic compounds containing nitrosourea and benzothiazine nucleus.

1997-01-01

The in vivo activity of 4 new benzothiazinyl-nitrosourea compounds was investigated against Sarcoma-180 (S-180) and Ehrlich Ascitic Carcinoma (EAC) induced ascitic and solid tumors. EAC solid tumor was found to be the most sensitive, where one compound (no 4) inhibited tumor growth to only 3 per cent of the control value. All the 4 compounds tested were found to be toxicologically more selective than 5-fluorouracil and 6-mercaptopurine drugs. The reason for this selective toxicity may be attributed to the inhibition of isocyanate moiety in these compounds which causes toxicity to normal cells via a carbamoylation reaction. However, they may still remain potent, since they decompose into an alkylating carbonium species and a charge transfer complex which may interact with DNA via alkylation and intercalation reactions, respectively.

Background and AimsComplications of portal hypertension, such as variceal hemorrhage and ascites, are associated with significant increases in both mortality and complications during pregnancy. Transjugular intrahepatic portosystemic shunt (TIPS) is a well-established procedure for treating portal hypertension, but the safety of TIPS during pregnancy is largely unknown. In this series, we review five patients who underwent TIPS placement while pregnant and describe their clinical outcomes.MethodsFive pregnant patients with cirrhosis and portal hypertension underwent elective TIPS for complications of portal hypertension (four for secondary prevention of variceal bleeding and one for refractory ascites). Outcomes measured were recurrent bleeding episodes or needmore » for further paracenteses during pregnancy, estimated radiation dose to the fetus and gestational age at delivery. All patients were followed after delivery to evaluate technical and clinical success of the procedure.ResultsAll five patients survived pregnancy and went on to deliver successfully. When TIPS was performed for secondary prevention of variceal bleeding (n = 4), no patients demonstrated variceal bleeding after TIPS placement. When TIPS was performed for refractory ascites (n = 1), no further paracenteses were required. All patients delivered successfully, albeit prematurely. Average radiation dose estimated to the fetus was 16.3 mGy.ConclusionsThis series suggests that TIPS can be performed in selective pregnant patients with portal hypertension, with little added risk to the mother or fetus.« less

Objective Natural killer (NK) cells represent a powerful immunotherapeutic target as they lyse tumors directly, do not require differentiation, and can elicit potent inflammatory responses. The objective of these studies was to use an IL-15 super-agonist complex, ALT-803 (Altor BioScience Corporation), to enhance the function of both normal and ovarian cancer patient derived NK cells by increasing cytotoxicity and cytokine production. Methods NK cell function from normal donor peripheral blood mononuclear cells (PBMCs) and ovarian cancer patient ascites was assessed using flow cytometry and chromium release assays +/− ALT-803 stimulation. To evaluate the ability of ALT-803 to enhance NK cell function in vivo against ovarian cancer, we used a MA148-luc ovarian cancer NOD scid gamma (NSG) xenogeneic mouse model with transferred human NK cells. Results ALT-803 potently enhanced functionality of NK cells against all ovarian cancer cell lines with significant increases seen in CD107a, IFNγ and TNFα expression depending on target cell line. Function was also rescued in NK cells derived from ovarian cancer patient ascites. Finally, only animals treated with intraperitoneal ALT-803 displayed an NK dependent significant decrease in tumor. Conclusions ALT-803 enhances NK cell cytotoxicity against ovarian cancer in vitro and in vivo and is able to rescue functionality of NK cells derived from ovarian cancer patient ascites. These findings suggest that ALT-803 has the potential to enhance NK-cell-based immunotherapeutic approaches for the treatment of ovarian cancer. PMID:28236454

Aim of the study To determine plausible associations between liver cirrhosis and circulating endothelial cell-derived microparticles (EMPs), vascular endothelial growth factor (VEGF) levels and plasma nitric oxide (NO) metabolites. Material and methods Sixty patients with cirrhosis and 20 healthy control subjects were enrolled in the study. Circulating EMPs from platelet-poor plasma samples were examined by flow cytometry. These microparticles were categorized into endothelial cell-derived activated MPs (EMP-ac) (CD31+ CD42b– AN-V–) and endothelial cell-derived apoptotic MPs (EMP-ap) (CD31+ CD42b– AN-V+). Plasma VEGF levels were measured by enzyme-linked immunosorbent assay. Plasma NO metabolites (NOx–) levels were determined using a Greiss reaction method. Results Compared with the healthy control subjects, the patients with cirrhosis showed a significant increase in plasma levels of both phenotypes of EMPs. When the presence of ascites was considered, the plasma levels of EMP-ap were higher (p < 0.01), as well as NOx– (p < 0.05). EMP-ap positively correlated with VEGF level in all cirrhotic patients and this correlation was stronger in decompensated cirrhotic patients. In multivariate logistic regression analysis, the independent factors associated with the presence of ascites were high EMP-ap levels and elevated VEGF levels. Conclusions Elevated plasma levels of EMP-ap in addition to high levels of VEGF might be considered as valuable parameters for predicting the occurrence of ascites in cirrhotic patients.

The Model for End-Stage Liver Disease (MELD) exception policy in liver transplantation is based on symptoms and clinical conditions not included in the calculated MELD score. Therefore, patients with chronic liver disease, like refractory ascites, chronic encephalopathy, recurrent cholangitis, and refractory pruritus, may benefit with extra points. The objective of this study was to establish the profile of the patients submitted to liver transplantation with MELD exceptions based on symptoms in the University Hospital Walter Cantídio, Ceara, Brazil, between the years of 2012 and 2015, analyzing donor and recipient data, with special attention to patients with refractory ascites and recurrent encephalopathy, including survival rates. The results demonstrated acceptable survival rates for MELD exception patients (78.4% in 3 years), showing that maybe this allocation criterion should be maintained, or even expanded.

Intraabdominal tuberculosis (TB) presents with a wide variety of clinical and radiologic features. Besides the reported computed tomographic (CT) finding of high-density ascites in tuberculous peritonitis, this report describes additional CT features highly suggestive of abdominal tuberculosis in eight cases: (1) irregular soft-tissue densities in the omental area; (2) low-density masses surrounded by thick solid rims; (3) a disorganized appearance of soft-tissue densities, fluid, and bowel loops forming a poorly defined mass; (4) low-density lymph nodes with a multilocular appearance after intravenous contrast administration; and (5) possibly high-density ascites. The differential diagnosis of these features include lymphoma, various forms ofmore » peritonitis, peritoneal carcinomatosis, and peritoneal mesothelioma. It is important that the CT features of intraabdominal tuberculosis be recognized in order that laparotomy be avoided and less invasive procedures (e.g., laparoscopy, biopsy, or a trial of antituberculous therapy) be instituted.« less

Imatinib mesylate (IM), a tyrosine kinase inhibitor, is the treatment of choice in patients with chronic myeloid leukemia (CML). It is considered a very safe drug, with mostly mild and reversible side effects. Lately, it has been suggested that adverse events may occur after a long term. We report a case of a 72-year-old woman diagnosed with blastic phase of Philadelphia chromosome positive CML treated with IM for 28 months. The patient presented first with ascites as a side effect of the drug. When the ascites re-occurred, it was caused by neuroendocrine tumor (NET) with peritoneal carcinomatosis. We believe this is the first case of a NET as a secondary malignancy (SM) after IM treatment. SM have been described in patients on IM before. It is unclear whether these tumors are caused by imatinib or found more easily because of close follow-up.

Age, Predisposing Diseases, and Ultrasonographic Findings in Determining Clinical Outcome of Acute Acalculous Inflammatory Gallbladder Diseases in Children

PubMed Central

2016-01-01

We evaluated clinical factors such as age, gender, predisposing diseases and ultrasonographic findings that determine clinical outcome of acute acalculous inflammatory gallbladder diseases in children. The patients were divided into the four age groups. From March 2004 through February 2014, clinical data from 131 children diagnosed as acute acalculous inflammatory gallbladder disease by ultrasonography were retrospectively reviewed. Systemic infectious diseases were the most common etiology of acute inflammatory gallbladder disease in children and were identified in 50 patients (38.2%). Kawasaki disease was the most common predisposing disease (28 patients, 21.4%). The incidence was highest in infancy and lowest in adolescence. The age groups were associated with different predisposing diseases; noninfectious systemic disease was the most common etiology in infancy and early childhood, whereas systemic infectious disease was the most common in middle childhood and adolescence (P = 0.001). Gallbladder wall thickening was more commonly found in malignancy (100%) and systemic infection (94.0%) (P = 0.002), whereas gallbladder distension was more frequent in noninfectious systemic diseases (60%) (P = 0.000). Ascites seen on ultrasonography was associated with a worse clinical course compared with no ascites (77.9% vs. 37.7%, P = 0.030), and the duration of hospitalization was longer in patients with ascites (11.6 ± 10.7 vs. 8.0 ± 6.6 days, P = 0.020). In conclusion, consideration of age and predisposing disease in addition to ultrasonographic gallbladder findings in children suspected of acute acalculous inflammatory gallbladder disease might result in better outcomes.

Albumin infusion reduces the incidence of postparacentesis circulatory dysfunction among patients with cirrhosis and tense ascites, as compared with no treatment. Treatment alternatives to albumin, such as artificial colloids and vasoconstrictors, have been widely investigated. The aim of this meta-analysis was to determine whether morbidity and mortality differ between patients receiving albumin versus alternative treatments. The meta-analysis included randomized trials evaluating albumin infusion in patients with tense ascites. Primary endpoints were postparacentesis circulatory dysfunction, hyponatremia, and mortality. Eligible trials were sought by multiple methods, including computer searches of bibliographic and abstract databases and the Cochrane Library. Results were quantitatively combined under a fixed-effects model. Seventeen trials with 1,225 total patients were included. There was no evidence of heterogeneity or publication bias. Compared with alternative treatments, albumin reduced the incidence of postparacentesis circulatory dysfunction (odds ratio [OR], 0.39; 95% confidence interval [CI], 0.27-0.55). Significant reductions in that complication by albumin were also shown in subgroup analyses versus each of the other volume expanders tested (e.g., dextran, gelatin, hydroxyethyl starch, and hypertonic saline). The occurrence of hyponatremia was also decreased by albumin, compared with alternative treatments (OR, 0.58; 95% CI, 0.39-0.87). In addition, mortality was lower in patients receiving albumin than alternative treatments (OR, 0.64; 95% CI, 0.41-0.98). This meta-analysis provides evidence that albumin reduces morbidity and mortality among patients with tense ascites undergoing large-volume paracentesis, as compared with alternative treatments investigated thus far.

Primary effusion lymphoma (PEL) is a rare B-cell neoplasm, associated with Kaposi sarcoma-associated herpes virus/human herpes virus-8 (KSHV/HHV-8), arising as malignant effusions in body cavities. PEL cells do not harbor conventional genetic cancer mutations; however, their oncogenesis is mainly attributed to HHV-8 latent genes. Treatment strategies are inefficient resulting in poor prognosis of PEL patients, stressing the need for new effective therapy. ST1926 is a synthetic retinoid with favorable antitumor properties and no cross-resistance with the natural retinoid, all-trans retinoic acid. ST1926 has shown potent apoptotic activities on a variety of solid tumors and hematologic malignancies in in vitro and in vivo models. In the present study we elucidated the antitumor activities and underlying molecular mechanism of ST1926 using in vitro, ex vivo, and in vivo PEL preclinical models. ST1926, at sub‑micromolar concentrations, displayed potent antiproliferative effects on PEL cell lines and malignant ascites. Furthermore, ST1926 treatment of PEL cells and ascites resulted in their accumulation in the sub-G1 region, S phase cell cycle arrest, early DNA damage, PARP cleavage and p53 activation including the upregulation of its target genes p21 and Bax. However, ST1926 did not significantly modulate HHV-8 latent viral transcripts. Importantly, ST1926 delayed formation of ascites and enhanced survival of PEL mice. These results highlight the therapeutic potential of ST1926 in combination with drugs that target HHV-8 in PEL patients.

To identify clinicopathologic factors associated with 10-year overall survival in epithelial ovarian cancer (EOC) and primary peritoneal cancer (PPC), and to develop a predictive model identifying long-term survivors. Demographic, surgical, and clinicopathologic data were abstracted from GOG 182 records. The association between clinical variables and long-term survival (LTS) (>10years) was assessed using multivariable regression analysis. Bootstrap methods were used to develop predictive models from known prognostic clinical factors and predictive accuracy was quantified using optimism-adjusted area under the receiver operating characteristic curve (AUC). The analysis dataset included 3010 evaluable patients, of whom 195 survived greater than ten years. These patients were more likely to have better performance status, endometrioid histology, stage III (rather than stage IV) disease, absence of ascites, less extensive preoperative disease distribution, microscopic disease residual following cyoreduction (R0), and decreased complexity of surgery (p<0.01). Multivariable regression analysis revealed that lower CA-125 levels, absence of ascites, stage, and R0 were significant independent predictors of LTS. A predictive model created using these variables had an AUC=0.729, which outperformed any of the individual predictors. The absence of ascites, a low CA-125, stage, and R0 at the time of cytoreduction are factors associated with LTS when controlling for other confounders. An extensively annotated clinicopathologic prediction model for LTS fell short of clinical utility suggesting that prognostic molecular profiles are needed to better predict which patients are likely to be long-term survivors.

The purpose of the present study was to investigate the therapeutic efficacy of 211At-labelled specific monoclonal antibody MOv18 in nude mice with intraperitoneal growth of the human ovarian cancer cell line OVCAR3. In the first part of the study the antibody was injected intraperitoneally when the cancer growth was microscopic. The injected activity was 485-555 kBq. The median survival for treated mice was 213 days compared to 138 days for untreated mice (p < 0.014, log-rank test). No obvious toxicity was seen. Thirty-three percent of the mice were apparently free of cancer after 7 months and were probably cured. In the second part of the study mice with macroscopic cancer and signs of ascites were injected intraperitoneally with the same 211At-labelled antibody (377-389 kBq). This treatment possibly delayed the production of ascites. Hopefully radioimmunotherapy with regionally administered 211At-labelled antibody will be of value in women with ovarian cancer as well.

Intestinal lymphangiectasia is defined as a dilatation of small bowel lymphatic capillaries and a loss of lymph into the bowel lumen. Clinically it is characterized by hypoproteinaemia and oedema. We present here a case of protein-losing enteropathy due to intestinal lymphangiectasia after liver transplantation in a 57-year-old man who was transplanted for hepatitis C virus. Four years after liver transplantation, the patient developed hypoalbuminaemia and ascites associated with recurrence of cirrhosis. The sudden fall in serum albumin led us to look for a cause of reduction other than or in addition to cirrhosis. Duodenal biopsies showed tall villi with dilated lymphatic vessels and widening of the villi caused by oedema, demonstrating intestinal lymphangiectasia. In this case a low-fat diet supplemented with medium-chain triacylglycerols achieved an early clinical improvement with increased serum albumin levels and ascites disappearance. Intestinal lymphangiectasia should be suspected in liver-transplanted patients developing hypoproteinaemia and hypoalbuminaemia after the recurrence of cirrhosis.

The gold standard for diagnosis of peritoneal tuberculosis is growth of Mycobacterium tuberculosis on ascitic fluid or peritoneal culture. Due to the nonspecific signs and symptoms of disease, its early diagnosis is difficult, especially in patients with decompensated cirrhosis. The reported sensitivity of ascitic fluid is low, and to obtain tissue for peritoneal biopsy in patients with cirrhosis is difficult. Thus, there is an urgent need to explore newer diagnostic modalities, especially those that can provide perioneal tissue by less invasive means. Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is a good alternative to obtain peritoneal tissue for establishing the diagnosis of peritoneal tuberculosis (TB). We hereby report the use of EUS- FNA of the peritoneum in five patients with decompensated cirrhosis, in whom the diagnosis could not be confirmed by other means; thus, we propose EUS-FNA of the peritoneum as a new, safe, and unexplored technique for diagnosis of peritoneal TB.

A 19-year-old male African penguin ( Spheniscus demersus ) was presented with coelomic distention after a 6-week history of lethargy and decreased appetite. Results of radiographs showed loss of coelomic detail, and ultrasound and computed tomography results revealed coelomic fluid and dilated hepatic veins. Echocardiography revealed moderate right atrial enlargement. Findings were consistent with right-sided cardiac disease. Treatment with furosemide initially reduced ascites, but the clinical condition worsened weeks later and enalapril, pimobendan, and sildenafil were added to the medical therapy. At 12 weeks after presentation, results of an echocardiogram revealed persistent right atrioventricular valve regurgitation, moderate ascites, and dilation of hepatic veins. Clinical signs of right heart failure were managed through adjustments in medical therapy and coelomic fluid aspiration, but the bird died 18 weeks after initial presentation. Gross and microscopic findings were consistent with valvular insufficiency and right-sided heart failure. To our knowledge, this case is the first documented report of cardiac disease in an African penguin.

The effect of the route administration on the distribution of radioiodinated OV-TL 3 F(ab')2 was studied in Balb/c female mice with intraperitoneal or subcutaneous ovarian carcinoma xenografts. In the intraperitoneal tumour model in which both ascites and solid tumour deposits were present, intraperitoneal administration resulted in a lower estimated radiation dose to blood as compared with intravenous administration. In this model normalization to equal estimated radiation doses to blood for both routes of administration indicated that a twice as high estimated radiation dose can be guided to solid intraperitoneal tumour deposits following intraperitoneal administration. Evacuation of ascitic tumour cells prior to monoclonal antibody injection further increased the estimated radiation dose to solid intraperitoneal tumour deposits following intraperitoneal delivery. Following simultaneous intravenous and intraperitoneal injection of the monoclonal antibody, tissue uptake showed no relevant differences in the subcutaneous tumour model. Overall, the intraperitoneal route of administration was found to be the best choice for therapeutic delivery of iodine-131 labelled monoclonal antibodies.

Four new ethylnitrosourea derivatives of substituted naphthalimides 3a-d have been synthesized from the respective N-(2-ethylamino) naphthalimides. Their chemical alkylating activity compared with the clinical drug CCNU and an experimental compound Mitonafide indicated that they possess lower alkylating activity than CCNU and comparable activity with the latter. Their anti-tumor efficacies were assessed in vivo in two murine ascites tumors namely Sarcoma-180 (S-180) and Ehrlich ascites carcinoma (EAC) by measuring the increase in median survival times (MST) of drug treated (T) over untreated control (C) mice. CCNU and Mitonafide were used as positive controls for comparison. The representative compound 3a has displayed marginal anti-tumoral activity in these tumors. Three compounds were further screened in vitro in 4 different human tumor cell lines but no significant activity was observed in those lines. These compounds moderately inhibit the synthesis of DNA and RNA in S-180 tumor cells.

Their chemical alkylating activity compared with nor -HN2 indicated that they possess greater alkylating activity than the latter. Their antitumour efficacies were assessed in vivo in two murine ascites tumours, namely Ehrlich ascites carcinoma (EAC) and Sarcoma-180 (S-180) by measuring the increase in median survival times (MST) of drug treated (T) over untreated control (C) mice. Two standard clinical drugs namely endoxan (cyclophosphamide) and 5-fluorouracil (5-FU) were used as positive controls for comparison. Both of them have displayed substantial and reproducible antitumoral activity in these tumours comparable with 5-FU. These were further screened in vitro in 6 different human tumour cell lines but no significant activity was observed in those lines.

Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

Intracellular putrescine and spermidine deprivation induces increased uptake of the natural polyamines and methylglyoxal bis(guanylhydrazone).

Inhibition of polyamine synthesis by alpha-difluoromethylornithine in cultured Ehrlich ascites-carcinoma cells rapidly enhanced the uptake of exogenous putrescine, spermidine and spermine from the culture medium. In tumour cells exposed to the drug for 2 days, the intracellular concentration of spermidine was decreased to less than 10% of that found in untreated cells. However, the strikingly stimulated transport system brought the concentration of spermidine to the control values in less than 2h after supplementation of the cells with micromolar concentrations of the polyamine. In the absence of polyamine deprivation, tumour cells did not accumulate extracellular polyamines to any appreciable extent. Ascites-tumour cells deprived of putrescine and spermidine likewise concentrated methylglyoxal bis(guanylhydrazone) [1,1'-[methylethanedylidine)dinitrilo]diguanidine] at a greatly enhanced rate. A previous "priming of tumour cells with difluoromethylornithine followed by an exposure of the cells to methylglyoxal bis(guanylhydrazone) resulted in a marked and rapid anti-proliferative effect.

Dengue fever in renal transplanted patients has not been studied well, and we review all the literature about episodes dengue fever in renal transplant patients. The aim was to describe clinico-pathological characteristics, immunosuppressive protocols, need renal outcome and mortality. PubMed, LILACS, Google Scholar and Research Gate were searched for "Dengue" and "Renal/Kidney Transplantation" with no date limits. Hits were analyzed by two researchers separately. Fever, myalgia, arthralgia and headache was significantly lower than normal population, while pleural effusions and ascites were observed more. Incidence of severe dengue is significantly higher among transplant patients in this review, as well as they had a significantly higher mortality (8.9% vs 3.7%, p = 0.031). Age, period after transplantation and immunosuppressive profile had no effect on disease severity, mortality or graft out come. Presence of new bleeding complications and ascites was associated with more severe disease (p < 0.001 and p = 0.005), death (p = 0.033) or graft loss (p = 0.035). Use of tacrolimus was associated with new bleeding complications (p = 0.027), and with ascites (p = 0.021), but not with thrombocytopenia. 25% of patients with primary disease fail to mount an IgG response by 15 weeks of the illness. 58.9% had graft dysfunction during illness. Postoperative transplanted patients were at risk of severe disease and unfavorable outcome. The physical and laboratory findings in dengue fever in renal transplanted patients differ from the general population. Some degree of graft dysfunction is common during the illness, but only a minority develops graft failure.

The creatine/creatine kinase system decreases drastically in sarcoma. In the present study, an investigation of catalytic activities, western blot and mRNA expression unambiguously demonstrates the prominent expression of the creatine-synthesizing enzymes l-arginine:glycine amidinotransferase and N-guanidinoacetate methyltransferase in sarcoma, Ehrlich ascites carcinoma and Sarcoma 180 cells, whereas both enzymes were virtually undetectable in normal muscle. Compared to that of normal animals, these enzymes remained unaffected in the kidney or liver of sarcoma-bearing mice. High activity and expression of mitochondrial arginase II in sarcoma indicated increased ornithine formation. Slightly or moderately higher levels of ornithine, guanidinoacetate and creatinine were observed in sarcoma compared to muscle. Despite the intrinsically low level of creatine in Ehrlich ascites carcinoma and Sarcoma 180 cells, these cells could significantly take up and release creatine, suggesting a functional creatine transport, as verified by measuring mRNA levels of creatine transporter. Transcript levels of arginase II, ornithine-decarboxylase, S-adenosyl-homocysteine hydrolase and methionine-synthase were significantly upregulated in sarcoma and in Ehrlich ascites carcinoma and Sarcoma 180 cells. Overall, the enzymes related to creatine and arginine/methionine metabolism were found to be significantly upregulated in malignant cells. However, the low levels of creatine kinase in the same malignant cells do not appear to be sufficient for the building up of an effective creatine/phosphocreatine pool. Instead of supporting creatine biosynthesis, l-arginine:glycine amidinotransferase and N-guanidinoacetate methyltransferase appear to be geared to support cancer cell metabolism in the direction of polyamine and methionine synthesis because both these compounds are in high demand in proliferating cancer cells.

Interstitial fluid accumulation can occur in pleural, pericardial, and peritoneal spaces, and subcutaneous tissue planes. The purpose of the study was to assess if whole body CT examination in a postmortem setting could help determine the presence and severity of third space fluid accumulation in the body. Our study included 41 human cadavers (mean age 61 years, 25 males and 16 females) who had whole-body postmortem CT prior to autopsy. All bodies were maintained in the morgue in the time interval between death and autopsy. Two radiologists reviewed the whole-body CT examinations independently to grade third space fluid in the pleura, pericardium, peritoneum, and subcutaneous space using a 5-point grading system. Qualitative CT grading for third space fluid was correlated with the amount of fluid found on autopsy and the quantitative CT fluid volume, estimated using a dedicated software program (Volume, Syngo Explorer, Siemens Healthcare). Moderate and severe peripheral edema was seen in 16/41 and 7/41 cadavers respectively. It is not possible to quantify anasarca at autopsy. Correlation between imaging data for third space fluid and the quantity of fluid found during autopsy was 0.83 for pleural effusion, 0.4 for pericardial effusion and 0.9 for ascites. The degree of anasarca was significantly correlated with the severity of ascites (p < 0.0001) but not with pleural or pericardial effusion. There was strong correlation between volumetric estimation and qualitative grading for anasarca (p < 0.0001) and pleural effusion (p < 0.0001). Postmortem CT can help in accurate detection and quantification of third space fluid accumulation. The quantity of ascitic fluid on postmortem CT can predict the extent of anasarca.

Ovarian cancer is the leading cause of death among gynecological malignancies. It is detected at late stages when the disease is spread through the abdominal cavity in a condition known as peritoneal carcinomatosis. Thus, there is an urgent need to develop novel therapeutic interventions to target advanced stages of ovarian cancer. Mammary serine protease inhibitor (Maspin) represents an important metastasis suppressor initially identified in breast cancer. Herein we have generated a sequence-specific zinc finger artificial transcription factor (ATF) to up-regulate the Maspin promoter in aggressive ovarian cancer cell lines and to interrogate the therapeutic potential of Maspin in ovarian cancer. We found that although Maspin was expressed in some primary ovarian tumors, the promoter was epigenetically silenced in cell lines derived from ascites. Transduction of the ATF in MOVCAR 5009 cells derived from ascitic cultures of a TgMISIIR-TAg mouse model of ovarian cancer resulted in tumor cell growth inhibition, impaired cell invasion, and severe disruption of actin cytoskeleton. Systemic delivery of lipid-protamine-RNA nanoparticles encapsulating a chemically modified ATF mRNA resulted in inhibition of ovarian cancer cell growth in nude mice accompanied with Maspin re-expression in the treated tumors. Gene expression microarrays of ATF-transduced cells revealed an exceptional specificity for the Maspin promoter. These analyses identified novel targets co-regulated with Maspin in human short-term cultures derived from ascites, such as TSPAN12, that could mediate the anti-metastatic phenotype of the ATF. Our work outlined the first targeted, non-viral delivery of ATFs into tumors with potential clinical applications for metastatic ovarian cancers. PMID:22782891

Spontaneous bacterial peritonitis (SBP) is a serious complication of liver cirrhosis with a high recurrence rate and a marked increase in mortality. Norfloxacin is used widely for the secondary prophylaxis of SBP; however, its extensive long-term use has led to an increase in the incidence of quinolone-resistant and Gram-positive SBP. Rifaximin is a nonabsorbable broad-spectrum antibiotic and does not appear to promote emergence of resistance. The aim of this study was to compare the safety and efficacy of rifaximin versus norfloxacin for the secondary prevention of SBP in patients with liver cirrhosis and ascites. Two hundred and sixty two cirrhotic patients with ascites and a previous episode of SBP were assigned randomly to receive either 1200 mg rifaximin or 400 mg of norfloxacin daily for 6 months. All patients were monitored clinically each month and with ascitic fluid examination at the end of 2 and 6 months if not clinically suspected of recurrence earlier. Recurrence of SBP was significantly lower in the rifaximin group (3.88 vs. 14.13%) compared with the norfloxacin group (P=0.04). The mortality rate was significantly decreased in the rifaximin group (13.74 vs. 24.43%) compared with the norfloxacin group (P=0.044). The causes of death between the two groups did not show a significant difference (P=0.377), but encephalopathy-related deaths were three folds higher in the norfloxacin group. There was a significant decrease in the side effects in the rifaximin group versus the norfloxacin group (P=0.033). Rifaximin was more effective than norfloxacin in the secondary prevention of SBP. Encephalopathy-related mortality and side effects were fewer in the rifaximin group.

The idea of acute-on-chronic liver failure (ACLF) has emerged to identify those subjects with organ failure and high mortality rates. However, the absence of a precise definition has limited the clinical application and research related to the ACLF concept. We sought to validate the ACLF definition and the CLIF-SOFA Score recently proposed by the EASL-CLIF Consortium in a cohort of patients admitted for acute decompensation (AD) of cirrhosis. In this prospective cohort study, patients were followed during their hospital stay and thirty and 90-day mortality was evaluated by phone call, in case of hospital discharge. All subjects underwent laboratory evaluation at admission. Between December 2010 and November 2013, 192 cirrhotic patients were included. At enrollment, 46 patients (24%) met the criteria for ACLF (Grades 1, 2 and 3 in 18%, 4% and 2% respectively). The 30-day mortality was 65% in ACLF group and 12% in the remaining subjects (P < 0.001). Logistic regression analysis showed that 30-day mortality was independently associated with ascites and ACLF at admission. The Kaplan-Meier survival probability at 90-day was 92% in patients without ascites or ACLF and only 22% for patients with both ascites and ACLF. The AUROC of CLIF-SOFA in predicting 30-day mortality was 0.847 ± 0.034, with sensitivity of 64%, specificity of 90% and positive likelihood ratio of 6.61 for values ≥9. In our single-centre experience the CLIF-SOFA and the EASL-CLIF Consortium definition of ACLF proved to be strong predictors of short-term mortality in cirrhotic patients admitted for AD. © 2014 John Wiley & Sons A/S.

Overexpression of sialomucin complex, a rat homologue of MUC4, inhibits tumor killing by lymphokine-activated killer cells.

PubMed

Komatsu, M; Yee, L; Carraway, K L

1999-05-01

Sialomucin complex (SMC) is a large heterodimeric glycoprotein complex composed of a mucin subunit ascites sialoglycoprotein-1 and a transmembrane subunit ascites sialoglycoprotein-2. It is a rat homologue of human mucin gene MUC4 and is abundantly expressed on the cell surface of highly metastatic ascites 13762 rat mammary adenocarcinoma cells. Because of their extended and rigid structures, mucin-type glycoproteins are suggested to have suppressing effects on cell-cell and cell-matrix interactions. During the metastatic process, these effects presumably cause tumor cell detachment from the primary tumor mass and facilitate escape of the tumor cells from immunosurveillance. Analyses of human breast cancer cells in solid tumors and tumor effusions showed that the more aggressive cells in effusions are stained with polyclonal antibodies against SMC more frequently than cells in solid tumors, suggesting a role for MUC4/SMC in tumor progression and metastasis. Previously, we generated recombinant cDNAs for SMC that vary in the number of mucin repeats to study the putative functions of SMC in tumor metastasis. These cDNAs were transfected into human cancer cell lines and tested for the effect of the expression of this gene. Here, using a tetracycline-responsive inducible expression system, we demonstrate that overexpression of SMC masks the surface antigens on target tumor cells and effectively suppresses tumor cell killing by cytotoxic lymphocytes. This effect results from the ability of SMC to block killer cell binding to the tumor cells and is dependent on both overexpression of the mucin and the number of mucin repeats in the expressed SMC. These results provide an explanation for the proposed role of SMC/MUC4 in tumor progression.

The primary objective was to evaluate the clinical efficacy of hu3S193, a humanized monoclonal antibody against the Lewis-Y antigen, in patients with platinum resistant/refractory ovarian, fallopian tube and primary peritoneal carcinoma. Secondary objectives were safety and pharmacokinetics. In addition, we sought to determine the potential interaction of clinical benefit and patient characteristics. This two-stage, multicenter, single arm, phase II trial enrolled eligible patients to receive hu3S193 weekly at a dose of 20mg/m(2) intravenously for 8 weeks (1 cycle) to a maximum of 3 cycles. Efficacy was measured as clinical benefit rate (objective response or stable disease for at least 24 weeks). 26 of 31 patients were eligible for efficacy analysis. No complete/partial responses were observed. Six patients had stable disease for 24+weeks [clinical benefit rate 23% (95% CI=9.77%-46.71%)]. Median PFS was 8.4 weeks (95% CI=6.0 to 16.1). Median PFS differed between patients with no ascites and no visceral disease and patients with ascites and/or visceral disease [16.1 vs. 8.1 weeks (p=0.0058)]. The most commonly reported treatment-related adverse events were fatigue (19.3%) and nausea (16.2%). Allergic reactions occurred in 6 patients (5 with Grade 1/2; 1 with Grade 3). Hu3S193 lacked sufficient activity in the first stage of the study to open enrollment to the second stage. However, based on the longer PFS in patients with no ascites and no visceral disease, consolidation strategies in platinum sensitive disease are currently being tested. Copyright © 2015 Elsevier Inc.

Enzymic determinations of intracellular concentrations of methylglyoxal-bis(guanylhydrazone), an anticancer drug which inhibits the synthesis of the polyamines spermidine and spermine, in cultured tumor cells revealed that the drug was remarkably effectively concentrated inside the cell. A concentration gradient across the cell membrane as great as 500--1000-fold was formed in cells exposed to the drug for 1-2 days. An exposure of cultured Ehrlich ascites carcinoma cells to increasing concentrations of the drug indicated that the cells could tolerate intracellular concentrations up to 1 mM with only slight changes in their proliferation rate. Micromolar concentrations of spermidine or spermine, but not putrescine, effectively blocked the uptake of methylglyoxal-bis(guanylhydrazone) and reduced the intracellular concentration of the drug below the levels required for growth inhibition. Analysis of cellular polyamine contents in Ehrlich ascites cells exposed to rising concentrations of methylglyoxal-bis(guanylhydrazone) gave little support to the view that the drug-induced growth inhibition was solely produced by an intracellular polyamine deprivation. Not only was the uptake of the drug inhibited in the presence of spermidine and spermine, but it was likewise washed out by polyamines from the cells that had been previously exposed to the drug and then transferred into drug-free medium in the presence of polyamines. For the inhibition of methylglyoxal-bis(guanylhydrazone) uptake by amines, three or more amino/imino groups were apparently required, since low concentrations of aliphatic diamines were either without any effect (short-chain diamines) or only marginally prevented (long-chain diamines) the uptake of the drug. High concentrations of Mg2+ ions, however, markedly inhibited the transport of the drug into Ehrlich ascites tumor cells.

Spontaneous bacterial peritonitis is the most common infectious complication in cirrhosis. Spontaneous fungal peritonitis is rare and remains unknown. In this work, spontaneous fungal peritonitis as well as risk factors and prognosis are characterized. A retrospective case-control study of 253 consecutive admissions by peritonitis in cirrhotic patients was carried out between 2006 and 2015. Comparison of patients with spontaneous fungal peritonitis (cases) and spontaneous bacterial peritonitis with positive microbiologic ascitic fluid culture (controls) was performed. Variables such as sociodemographic and clinical features, cirrhosis etiology, liver dysfunction scores, ascitic and laboratory parameters, invasive procedures, and prognosis were evaluated. Of the 231 patients, eight (3.5%) developed spontaneous fungal peritonitis, 62.5% of cases being coinfected with bacteria. Candida spp. was isolated in 87.5% of cases, mainly Candida albicans (37.5%) and C. krusei (25.0%). Patients with spontaneous fungal peritonitis had higher ascitic fluid lactate dehydrogenase (288.4±266.6 vs. 161.0±179.5; P=0.011), blood leukocyte count (15187.5±5432.3 vs. 10969.8±6949.5; P=0.028), blood urea nitrogen (69.8±3.1 vs. 36.3±25.5; P=0.001), higher number of invasive procedures (colonoscopy: 25.0 vs. 0.8%, P=0.001; urinary catheterization: 87.5 vs. 49.6%, P=0.038; nasogastric intubation: 87.5 vs. 26.9%, P=0.001), and longer duration of hospital stay (30.0±32.9 vs. 18.9±17.0 days; P=0.031). No statistical difference was found between the two groups for Model for End-Stage Liver Disease, Model for End-Stage Liver Disease-sodium, and Child-Pugh scores. Spontaneous fungal peritonitis was associated with a worse prognosis, particularly severe sepsis/septic shock (87.5 vs. 42.8%, P=0.023), admission in the gastroenterology intensive care unit (87.5 vs. 24.4%; P=0.001), and overall (62.5 vs. 31.9%; P=0.039) or 30-day mortality (50.0 vs. 24.4%; P=0.034), with a mean diagnosis

To compare the outcomes of umbilical hernia repair in patients with and without signs of portal hypertension, such as esophageal varices or ascites; to assess the effect of emergency surgery on complication rates; and to identify predictors of postoperative mortality. Database search from January 1, 2005, through December 31, 2009. North American hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program initiative. We studied patients who underwent umbilical hernia repair. Those with congestive heart failure, disseminated malignant tumor, or chronic renal failure while undergoing dialysis were excluded. Preoperative variables and perioperative course were analyzed. Main outcome measures were morbidity and mortality after umbilical hernia repair. A total of 390 patients with ascites and/or esophageal varices formed the study group, and the remaining 22 952 patients formed the control group. The overall morbidity and mortality rates for the study group were 13.1% and 5.1%, whereas these rates were 3.9% and 0.1% for the control group, respectively (P < .001). For the study group, the mortality after elective repair among patients with a model for end-stage liver disease (MELD) score greater than 15 was 11.1% compared with 1.3% in patients with a MELD score of 15 or less. The patients with ascites and/or esophageal varices underwent emergency surgery more frequently than the control group (37.7% vs 4.9%; P < .001). Emergency surgery for the study group was associated with a higher morbidity than elective surgery (20.8% vs 8.3%; P < .001) but not a significantly higher mortality (7.4% vs 3.7%; P = .11). However, logistic regression analysis showed that age older than 65 years, MELD score higher than 15, albumin level less than 3.0 g/dL (to convert to grams per liter, multiply by 10), and sepsis at presentation were more predictive of postoperative mortality.

Isolated ruptures of the urinary bladder following minor traumas are a rare abdominal lesion. Diagnosis and treatment are a challenge to emergency physicians and surgeons. This case shows a 46-year-old patient admitted for a minor brain injury after falling during an episode of alcoholic intoxication. Ultrasound and CT scan of the abdomen showed intraabdominal fluid without a parenchymatous lesion. Also a hematuria was significant. The retrograde cystography showed intraabdominal contrast agent. The rupture of the urinary bladder was confirmed by laparoscopy and was intracorporal sutured in double layer technique. Without any postoperative complications the patient was discharged after 4 days. The retrograde cystography after 10 days showed no leckage and the urinary catheter could be removed.

The purpose of this study is to investigate the clinical characteristics to determine the optimal timing of interval debulking surgery following neoadjuvant chemotherapy in patients with advanced epithelial ovarian cancer. We reviewed the charts of women with advanced epithelial ovarian cancer, fallopian tube cancer or primary peritoneal cancer who underwent interval debulking surgery following neoadjuvant chemotherapy at our cancer center from April 2006 to April 2014. There were 139 patients, including 91 with ovarian cancer [International Federation of Gynecology and Obstetrics (FIGO) Stage IIIc in 56 and IV in 35], two with fallopian tube cancers (FIGO Stage IV, both) and 46 with primary peritoneal cancer (FIGO Stage IIIc in 27 and IV in 19). After 3-6 cycles (median, 4 cycles) of platinum-based chemotherapy, interval debulking surgery was performed. Sixty-seven patients (48.2%) achieved complete resection of all macroscopic disease, while 72 did not. More patients with cancer antigen 125 levels ≤25.8 mg/dl at pre-interval debulking surgery achieved complete resection than those with higher cancer antigen 125 levels (84.7 vs. 21.3%; P< 0.0001). Patients with no ascites at pre-interval debulking surgery also achieved a higher complete resection rate (63.5 vs. 34.1%; P< 0.0001). Moreover, most patients (86.7%) with cancer antigen 125 levels ≤25.8 mg/dl and no ascites at pre-interval debulking surgery achieved complete resection. A low cancer antigen 125 level of ≤25.8 mg/dl and the absence of ascites at pre-interval debulking surgery are major predictive factors for complete resection during interval debulking surgery and present useful criteria to determine the optimal timing of interval debulking surgery. © The Author 2016.

To confirm the safety and effectiveness of techniques to assist radiofrequency ablation (RFA) for difficult cases, we retrospectively evaluated successful treatment rates, early complications and local tumor progressions. Between June 1999 and April 2009, a total of 341 patients with 535 nodules were treated as difficult cases. Artificial pleural effusion assisted ablation was performed on 64 patients with 82 nodules. Artificial ascites-assisted ablation was performed on 11 patients with 13 nodules. Cooling by endoscopic nasobiliary drainage (ENBD) tube-assisted ablation was performed on 6 patients with 8 nodules. When the tumors were not well visualized with conventional B-mode ultrasonography (US), contrast-enhanced US-assisted ablation with Levovist or Sonazoid or virtual CT sonography-assisted ablation was performed. Contrast-enhanced US-assisted ablation was performed on 139 patients with 224 nodules and virtual CT sonography-assisted ablation was performed on 121 patients with 209 nodules. In total, complete ablation was achieved in 514 of 535 (96%) nodules in difficult cases. For RFA with artificial pleural effusion, artificial ascites and ENBD, complete response was confirmed in all cases. For contrast-enhanced US- and CT sonography-assisted ablation, complete response was 95%. Early complications were recognized in 24 cases (4.5%). All cases recovered with no invasive treatment. Local tumor recurrence was investigated in 377 nodules of 245 patients, and 69 (18%) nodules were positive. Tumor recurrences in each assisted technique were 14.7% in artificial pleural effusion cases, 7% in artificial ascites, 12.5% in ENBD tube cases, 31% in virtual CT sonography, and 8.5% in contrast-enhanced US. Although local tumor progression needs to be carefully monitored, assisted techniques of RFA for difficult cases are well tolerated and expand the indications of RFA. Copyright (c) 2010 S.

Infections in patients affected by liver cirrhosis: an update.

PubMed

Ascione, Tiziana; Di Flumeri, Giusy; Boccia, Giovanni; De Caro, Francesco

2017-06-01

Patients with liver cirrhosis present an increased incidence of infections. The main cause has been founded in alterations of the enteric flora and of the intestinal barrier probably due to portal hypertension, in addition to a reticulo-endothelial system dysfunction. Furthermore, those living with cirrhosis can report a high predisposition to sepsis and septic shock, due to the excessive response of pro-inflammatory cytokines and a complessive hemodynamic derangement. By the analysis in the experimental model of the cirrhotic rat, it was demonstrated that radio-labelled Escherichia coli given by the oral route resulted in the location of the bacteria in the gut, the ascitic fluid and mesenteric lymph nodes, a phenomenon known as bacterial translocation. Bacteria encountered with the highest frequency are those colonizing the intestinal tract, such as E. coli, Klebsiella pneumoniae and Enterobacteriaceae, intracellular bacteria and parasites are reported with a lower frequency. Multi-drug resistant bacteria are cultured with the highest frequency in those with frequent hospitalisations and report both high septic shock and mortality rates. Spontaneous bacterial peritonitis (SBP) is the commonest infection in cirrhotic, estimated to occur in 10-30% of the cases with ascites. A practical approach may include administration of a protected penicillin, III generation cephalosporin or quinolones in uncomplicated cases. Instead, in complicated cases and in nosocomial SBP, administration of cephalosporin or quinolones can be burned by the high resistance rate and drugs active against ESBL-producing bacteria and multi-drug resistant Gram positive bacteria have to be considered as empiric therapy, until cultures are available. When cultures are not readily available and patients fail to improve a repeated diagnostic paracentesis should be performed. Current investigations suggest that norfloxacin 400 mg/day orally has been reported to successfully prevent SBP in patients

Failure to rescue (FTR) is a key metric of perioperative morbidity and mortality. We review perioperative medical comorbidities (MCMs) to determine what factors are associated with complications and rates of FTR. A retrospective review of a NSQIP database including general, vascular, and surgical subspecialty patients from a tertiary referral center between March 2008 and March 2013 was performed. Demographics, MCMs, complications, 30-day mortality, and risk of FTR associated with specific complications and MCM were evaluated. A total of 7,763 patients were included; 52.6% had MCMs and 14% (n = 1,099) experienced a complication. Patients with complications were older (64.9 vs 55 years; p < 0.001), more likely male (54% vs 44%; p < 0.001), and had more MCMs per patient (1.6 vs 1.4; p < 0.001). Complications were also associated with renal failure (odds ratio [OR] = 1.4; 95% CI, 1.0-2.0), steroid use (OR = 1.9; 95% CI, 1.4-2.5), CHF (OR = 2.5; 95% CI, 1.2-5.1), and ascites (OR = 9.1; 95% CI, 3.7-21.7), but not diabetes, hypertension, or COPD. There were 117 (11%) deaths among patients with complications. Adjusting for age, sex, American Society of Anesthesiologists class, and number of comorbidities, FTR was associated with postoperative respiratory failure, sepsis, and renal failure, as well as comorbid CHF, renal failure, ascites, and disseminated cancer. Specific comorbidities are associated with higher rates of complications and FTR. Preoperative CHF, renal failure, and ascites, which were associated with FTR, can reflect a physiologic inability to tolerate complication-induced fluid shifts. Postoperative mortality was associated with signs of end organ damage, including sepsis, respiratory failure, and renal failure. Earlier recognition of these complications in at-risk patients should improve rates of FTR. Copyright © 2015 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Background Tumor resistance to platinum-based drugs has been an obstacle to the treatment of ovarian cancer. Extract of the plant Rauwolfia vomitoria has long been used by cancer patients. However, there have not been systematic studies of its anticancer activity. Objective In an effort to enhance the effectiveness of platinum-based drugs, we investigated the anticancer effect of a Rauwolfia vomitoria extract (Rau), both alone and in combination with carboplatin (Cp). Methods In vitro cytotoxicity and colony formation were evaluated in several ovarian cancer cell lines. In vivo effects were evaluated in an intraperitoneal ovarian cancer mouse model. The combination of Rau and Cp was assessed using Chou-Talalay’s constant ratio design and median effect analysis based on the isobologram principle to determine the combination index values. Results Rau decreased cell growth in all 3 tested ovarian cancer cell lines dose dependently and completely inhibited formation of colonies in soft agar. Apoptosis was induced in a time- and dose-dependent manner and was the predominant form of Rau-induced cell death. Synergy of Rau with Cp was detected, with combination index values <1 and dose reduction index values for Cp ranging from 1.7- to 7-fold. Tumor growth in mice was significantly suppressed by 36% or 66% with Rau treatment alone at a low (20 mg/kg) or a high dose (50 mg/kg), respectively, an effect comparable to that of Cp alone. The volume of ascitic fluid and the number of nonblood cells in ascites were also significantly decreased. Combining Rau with Cp remarkably enhanced the effect of Cp and reduced tumor burden by 87% to 90% and ascites volume by 89% to 97%. Conclusions Rau has potent antitumor activity and in combination significantly enhances the effect of Cp against ovarian cancer. PMID:24465036

The aim of the present study was to investigate the reversal effect and its related mechanism of Ginkgo biloba exocarp extracts (GBEEs) in obtained multidrug resistance (MDR) of mice S180 tumor cells in vitro and in vivo. In order to simulate the clinical PFC [cis-dichlorodiamineplatinum, cisplatin (DDP) + fluorouracil (FU), FU+cyclophosphamide and cyclophosphamide] scheme, a gradually increasing dose was administered in a phased induction in order to induce S180 cells in vivo and to make them obtain multidrug resistance. The results in vitro demonstrated that GBEE could significantly increase the IC50 of DDP on S180 MDR cells, increase the accumulation of Adriamycin (ADR) and rhodamine 123 (Rho 123), and reduce the efflux of Rho 123 of S180 MDR cells. The results from the in vivo treatment with a combination of GBEE and DDP to S180 MDR ascites tumor in mice demonstrated that each dose of GBEE could effectively reverse the drug-resistance of S180 MDR cells to DDP in order to extend the survival time of mice with ascite tumors and inhibit tumor growth in solid tumor mice. In addition, GBEE effectively inhibited the expression of MDR-1 mRNA and multidrug resistance-associated protein-1 mRNA in S180 MDR cells of ascites tumor in mice and improved the expression levels of cytokines, including interleukin (IL)-3, IL-18 and interferon-γ in the blood serum of S180 MDR tumor-bearing mice. The present study showed that the mechanism of GBEE reversal of MDR may be associated with the inhibition of the functional activity of P-glycoprotein, the downregulation of drug resistance related gene expression of S180 MDR cells and the improvement of the production of related serum cytokines of S180 MDR tumor mice.

Although the induction of cytochrome P450 (CYP) has long been investigated in patients with cirrhosis, the question whether liver dysfunction impairs the response to CYP inducers still remains unresolved. Moreover, the mechanism underlying the possible effect of cirrhosis on induction has not been investigated. Since ethical constraints do not permit methodologically rigorous studies in humans, this question was addressed by investigating the effect of the prototypical inducer benzo[a]pyrene (BP) on CYP1A1 and CYP1A2 in cirrhotic rats stratified according to the severity of liver dysfunction. We simultaneously assessed mRNA level, protein expression and enzymatic activity of the CYP1A enzymes, as well as mRNA and protein expressions of the aryl hydrocarbon receptor (AhR), which mediates the BP effect. Basal mRNA and protein expressions of CYP1A1 were virtually absent in both healthy and cirrhotic rats. On the contrary, CYP1A2 mRNA, protein and enzyme activity were constitutively present in healthy rats and decreased significantly as liver function worsened. BP treatment markedly increased the concentrations of mRNA and immunodetectable protein, and the enzymatic activities of both CYP1A enzymes to similar levels in healthy and non-ascitic cirrhotic rats. Induced mRNA levels, protein expressions and enzymatic activities of both CYPs were much lower in ascitic rats and were proportionally reduced. Both constitutive and induced protein expressions of AhR were significantly lower in ascitic than in healthy rats. These results indicate that the inducibility of CYP1A enzymes is well preserved in compensated cirrhosis, whereas it is markedly reduced when liver dysfunction becomes severe. Induction appears to be impaired at the transcriptional level, due to the reduced expression of AhR, which controls the transcription of CYP1A genes. PMID:23626760

In advanced cirrhosis, gut bacterial translocation is the consequence of intestinal barrier disruption and leads to bacterial infection. Bile acid abnormalities in cirrhosis could play a role in the integrity of the intestinal barrier and the control of microbiota, mainly through the farnesoid X receptor. We investigated the long-term effects of the farnesoid X receptor agonist, obeticholic acid, on gut bacterial translocation, intestinal microbiota composition, barrier integrity and inflammation in rats with CCl4-induced cirrhosis with ascites. Cirrhotic rats received a 2-week course of obeticholic acid or vehicle starting once ascites developed. We then determined: bacterial translocation by mesenteric lymph node culture, ileum expression of antimicrobial peptides and tight junction proteins by qPCR, fecal albumin loss, enteric bacterial load and microbiota composition by qPCR and pyrosequencing of ileum mucosa-attached contents, and intestinal inflammation by cytometry of the inflammatory infiltrate. Obeticholic acid reduced bacterial translocation from 78.3% to 33.3% (p<0.01) and upregulated the expression of the farnesoid X receptor-associated gene small heterodimer partner. Treatment improved ileum expression of antimicrobial peptides, angiogenin-1 and alpha-5-defensin, tight junction proteins zonulin-1 and occludin, and reduced fecal albumin loss and liver fibrosis. Enteric bacterial load normalized, and the distinctive mucosal microbiota of cirrhosis was reduced. Gut immune cell infiltration was reduced and inflammatory cytokine and Toll-like receptor 4 expression normalized. In ascitic cirrhotic rats, obeticholic acid reduces gut bacterial translocation via several complementary mechanisms at the intestinal level. This agent could be used as an alternative to antibiotics to prevent bacterial infection in cirrhosis. Copyright © 2016 European Association for the Study of the Liver. Published by Elsevier B.V.

Abstract Hospitalizations for advanced liver disease are costly and associated with significant mortality. This population-based study aimed to evaluate factors associated with in-hospital mortality and resource use for the management of hospitalized patients with cirrhosis. Mortality records and resource utilization for 52,027 patients hospitalized with cirrhosis and/or complications of portal hypertension (ascites, hepatic encephalopathy, variceal bleeding, spontaneous bacterial peritonitis, or hepatorenal syndrome) were extracted from a nationally representative sample of Thai inpatients covered by Universal Coverage Scheme during 2009 to 2013. The rate of dying in the hospital increased steadily by 12% from 9.6% in 2009 to 10.8% in 2013 (P < .001). Complications of portal hypertension were independently associated with increased in-hospital mortality except for ascites. The highest independent risk for hospital death was seen with hepatorenal syndrome (odds ratio [OR], 5.04; 95% confidence interval [CI], 4.38–5.79). Mortality rate remained high in patients with infection, particularly septicemia (OR, 4.26; 95% CI, 4.0–4.54) and pneumonia (OR, 2.44; 95% CI, 2.18–2.73). Receiving upper endoscopy (OR, 0.29; 95% CI, 0.27–0.32) and paracentesis (OR, 0.93; 95% CI, 0.87–1.00) were associated with improved patient survival. The inflation-adjusted national annual costs (P = .06) and total hospital days (P = .07) for cirrhosis showed a trend toward increasing during the 5-year period. Renal dysfunction, infection, and sequelae of portal hypertension except for ascites were independently associated with increased resource utilization. Renal dysfunction, infection, and portal hypertension-related complications are the main factors affecting in-hospital mortality and resource utilization for hospitalized patients with cirrhosis. The early intervention for modifiable factors is an important step toward improving hospital outcomes. PMID:28796076

Molecular-based techniques reduce the delay in diagnosing infectious diseases and therefore contribute to better patient outcomes. We assessed the FilmArray blood culture identification (BCID) panel (Biofire Diagnostics/bioMérieux) directly on clinical specimens other than blood: cerebrospinal, joint, pleural and ascitic fluids, bronchoscopy samples and abscesses. We compared the results from 88 samples obtained by culture-based techniques. The percentage of agreement between the two methods was 75 % with a Cohen κ value of 0.51. Global sensitivity and specificity using the FilmArray BCID panel were 71 and 97 %, respectively. Sensitivity was poorer in samples with a low bacterial load, such as ascitic and pleural fluids (25 %), whereas the sensitivity for abscess samples was high (89 %). These findings suggest that the FilmArray BCID panel could be useful to perform microbiological diagnosis directly from samples other than positive blood cultures, as it offers acceptable sensitivity and moderate agreement with conventional microbiological methods. Nevertheless, cost-benefit studies should be performed before introducing this method into algorithms for microbiological diagnostics.

Development, characterization, and use of monoclonal and polyclonal antibodies against the myxosporean, Ceratomyxa shasta

Both monoclonal and polyclonal antisera were produced against Ceratomyxa shasta. Ascites containing trophozoites of the parasite was collected from infected fish and used as antigen for immunization of mice. The resulting monoclonal antibodies reacted specifically with trophozoite and sporoblast stages but did not react with C. shasta spores by either indirect fluorescent antibody techniques or in Western blots. This indicates that some C. shasta antigens are specific to certain life stages of the parasite. Polyclonal antiserum was produced in a rabbit by injecting a spore protein electro-eluted from an SDS-polyacrylamide gel. This antiserum reacted with both trophozoites and spores by indirect fluorescent antibody techniques and in Western blots. All antisera were tested for cross-reactivity to trout white blood cells, a contaminant of the ascites, and to other myxosporea. Two monoclonal antibodies reacted with white blood cells and myxosporea of the genera Sphaerospora and Myxobilatus. One hybridoma produced antibodies of high specificity for C. shasta pre-spore stages. This is the first report of a monoclonal antibody produced against a myxosporean parasite.

Chemotherapy-induced cerebrospinal fluid malabsorption in a shunted child: case report and review of the literature

Ventriculoperitoneal (VP) shunt insertion is one of the most common neurosurgical procedures for the treatment of chronic hydrocephalus. Although regarded as a relatively benign procedure, several complications including obstruction, infection and mechanical failure can be seen during the postoperative stage. Symptomatic sterile cerebrospinal fluid (CSF) ascites and hydrothoracies are rare complications of VP shunt surgery. The paucity of cases makes identifying the aetiological factors difficult, particularly without catheter tip migration. It is most likely that several factors interact to reduce the absorption of CSF. The authors discuss the case of a 5-year-old girl who developed CSF ascites and a pleural effusion after starting chemotherapy for a suprasellar pilocytic astrocytoma, 2 years post-VP shunt insertion, due to a secondary obstructive hydrocephalus. After the initial management of the presenting symptoms, the child's VP shunt was subsequently changed to a ventriculo-atrial shunt and the patient made an unremarkable recovery. We also review the literature pertaining to this rare complication, assessing identifiable risk factors and surgical management options. PMID:23396932

The identification of immunosuppressive factors within human tumor microenvironments, and the ability to block these factors, would be expected to enhance patients’ anti-tumor immune responses. We previously established that an unidentified factor, or factors, present in ovarian tumor ascites fluids reversibly inhibited the activation of T cells by arresting the T cell signaling cascade. Ultracentrifugation of the tumor ascites fluid has now revealed a pellet that contains small extracellular vesicles (EV) with an average diameter of 80nm. The T cell arrest was determined to be causally linked to phosphatidylserine (PS) that is present on the outer leaflet of the vesicle bilayer, as a depletion of PS expressing EV or a blockade of PS with anti-PS antibody significantly inhibits the vesicle induced signaling arrest. The inhibitory EV were also isolated from solid tumor tissues. The presence of immune suppressive vesicles in the microenvironments of ovarian tumors and our ability to block their inhibition of T cell function represent a potential therapeutic target for patients with ovarian cancer.

We sought to identify the most relevant hemofilter for cytokine removal based on the mechanisms of filtration and adsorption. Ascites were filtered using four types of hemofilters composed of different membrane materials (polymethyl methacrylate, PMMA, cellulose triacetate, CTA, or polysulfone, PS) and different surface areas (1.0 or 2.1 m(2)) to investigate the rate of interleukin-6 (IL-6) filtration. Next, ascites were perfused through each hemofilter without obtaining a filtrate to study each filter's adsorptive capability. The PMMA hemofilters resulted in a marginal observed IL-6 filtration rates, whereas the CTA and PS hemofilters resulted in highly effective IL-6 filtration. Regarding the IL-6 adsorptive capabilities of the filters, the PMMA hemofilter with a large surface area showed the highest level of IL-6 clearance. The present findings suggest that when cytokine removal based on filtration is desired, CTA or PS hemofilters should be selected. When IL-6 removal based on adsorption is desired, a PMMA hemofilter with a large surface area should be selected. Copyright © 2010 S. Karger AG, Basel.

The lymphokine B-cell stimulatory factor 1 (BSF-1) has been shown to greatly enhance the differentiation of lipopolysaccharide-activated B cells into IgG1- and IgE-secreting cells in vitro. To determine whether in vivo IgG1 and IgE antibody responses are BSF-1 dependent, the ability of a monoclonal rat IgG1 anti-BSF-1 antibody, 11B11, to affect polyclonal IgG1 and IgE production in mice infected with the nematode parasite Nippostrongylus brasiliensis or injected with a purified goat antibody to mouse IgD was studied. 11B11-containing ascites fluid or purified 11B11 strongly inhibited IgE production in both systems but did not affect IgG1 production, while control ascites or normal rat IgG1 had no IgE-inhibitory activity. These results indicate an important physiologic role for BSF-1 in the generation of IgE antibody responses and suggest means for limiting the production of antibodies responsible for allergic reactions without inhibiting protective antibody responses.

Conventional wisdom teaches that small hernia defects are more likely to incarcerate. We aim to identify radiographic features of ventral hernias associated with increased risk of bowel incarceration. We assessed all patients who underwent emergent ventral hernia repair for bowel complications from 2009 to 2015. Cases were matched 1:3 with elective controls. Computed tomography scans were reviewed to determine hernia characteristics. Univariate and multivariable analyses were performed to identify variables associated with emergent surgery. The cohort consisted of 88 patients and 264 controls. On univariate analysis, older age, higher ASA score, elevated BMI, ascites, larger hernias, small angle, and taller hernias were associated with emergent surgery. On multivariable analysis, morbid obesity, ascites, smaller angle, and taller hernias were independently associated with emergent surgery. The teaching that large defects do not incarcerate is inaccurate; bowel compromise occurs with ventral hernias of all sizes. Instead, taller height and smaller angle are associated with the need for emergent repair. Early elective repair should be considered for patients with hernia features concerning for increased risk of bowel compromise. Copyright © 2016 Elsevier Inc. All rights reserved.

Ovarian cancer patients often suffer from malignant ascites and pleural effusion. Apart from worsening the outcome, this condition frequently impairs the quality of life in patients who are already distressed by ovarian cancer. This study investigated whether single intraperitoneal administration of the anti-VEGF antibody bevacizumab is capable of reducing the ascites-related body surface and prolonging survival. The study was performed in an orthotopic murine model of peritoneal disseminated platin-resistant ovarian cancer. Mice were treated with bevacizumab and/or paclitaxel or buffer (control). Reduction of body surface and increased survival rates were assessed as therapeutic success. Survival of mice in all treatment groups was significantly enhanced when compared to the non-treatment control group. The combination of paclitaxel plus bevacizumab significantly improved body surface as well as overall survival in comparison to a treatment with only one of the drugs. Treatment of malignant effusion with a single dose of bevacizumab as an intraperitoneal application, with or without cytostatic co-medication, may be a powerful alternative to systemic treatment.

To describe peritoneal manifestations of fascioliasis on CT. We reviewed CT images in 31 patients with fascioliasis confirmed by enzyme-linked immunosorbent assay (ELISA) (n = 24) or surgery (n = 7). Image analyses were performed to identify hepatic, biliary, and peritoneal abnormalities. Hepatic abnormalities were seen in 28 (90.3 %) of the 31 patients. The most common finding was caves sign, which was present in 25 (80.1 %) patients. Three patients (9.7 %) presented with biliary abnormalities exhibiting dilatation and enhancing wall thickening of the bile duct, wall thickening of the gallbladder, and elongated structures in the bile duct or gallbladder. Peritoneal abnormalities were seen in 14 (45.2 %) of the 31 patients. The most common peritoneal abnormality was mesenteric or omental infiltration, which was seen in 9 (29.0 %) patients. Other peritoneal findings included lymph node enlargement (n = 7), ascites (n = 7), thickening of ligamentum teres (n = 2), and peritoneal mass (n = 2). Peritoneal manifestations of fascioliasis are relatively common, and CT findings include mesenteric or omental infiltration, lymph node enlargement, ascites, thickening of the ligamentum teres, and peritoneal masses.

Inflammation: a way to understanding the evolution of portal hypertension

Aller, María-Angeles; Arias, Jorge-Luis; Cruz, Arturo; Arias, Jaime

2007-01-01

Background Portal hypertension is a clinical syndrome that manifests as ascites, portosystemic encephalopathy and variceal hemorrhage, and these alterations often lead to death. Hypothesis Splanchnic and/or systemic responses to portal hypertension could have pathophysiological mechanisms similar to those involved in the post-traumatic inflammatory response. The splanchnic and systemic impairments produced throughout the evolution of experimental prehepatic portal hypertension could be considered to have an inflammatory origin. In portal vein ligated rats, portal hypertensive enteropathy, hepatic steatosis and portal hypertensive encephalopathy show phenotypes during their development that can be considered inflammatory, such as: ischemia-reperfusion (vasodilatory response), infiltration by inflammatory cells (mast cells) and bacteria (intestinal translocation of endotoxins and bacteria) and lastly, angiogenesis. Similar inflammatory phenotypes, worsened by chronic liver disease (with anti-oxidant and anti-enzymatic ability reduction) characterize the evolution of portal hypertension and its complications (hepatorenal syndrome, ascites and esophageal variceal hemorrhage) in humans. Conclusion Low-grade inflammation, related to prehepatic portal hypertension, switches to high-grade inflammation with the development of severe and life-threatening complications when associated with chronic liver disease.

Multicellular detachment generates metastatic spheroids during intra-abdominal dissemination in epithelial ovarian cancer.

Ovarian cancer is the most lethal gynecological cancer, where survival rates have had modest improvement over the last 30 years. Metastasis of cancer cells is a major clinical problem, and patient mortality occurs when ovarian cancer cells spread beyond the confinement of ovaries. Disseminated ovarian cancer cells typically spread within the abdomen, where ascites accumulation aids in their transit. Metastatic ascites contain multicellular spheroids, which promote chemo-resistance and recurrence. However, little is known about the origin and mechanisms through which spheroids arise. Using live-imaging of 3D culture models and animal models, we report that epithelial ovarian cancer (EOC) cells, the most common type of ovarian cancer, can spontaneously detach as either single cells or clusters. We report that clusters are more resistant to anoikis and have a potent survival advantage over single cells. Using in vivo lineage tracing, we found that multicellular spheroids arise preferentially from collective detachment, rather than aggregation in the abdomen. Finally, we report that multicellular spheroids from collective detachment are capable of seeding intra-abdominal metastases that retain intra-tumoral heterogeneity from the primary tumor.

Proteinuria is one of the characteristic adverse events by ramucirumab(RAM)plus paclitaxel(PTX)combination therapy for advanced gastric cancer. We reported a case of recurrent gastric cancer with grade(gr)3 proteinuria caused by RAM plus PTX therapy. 77-year-old woman was underwent distal gastrectomy in 76 years old for gastric cancer that was diagnosed mucinous adenocarcinoma, fStage III C(T4aN3H0P0CY0M0)and received adjuvant chemotherapy of S-1 for 1 year. She suffered from peritoneal recurrence with ascites after 1 year and 4 months of the operation and RAM(8mg/kg; day 1 and 15)plus PTX(80mg/m2; day 1, 8 and 15)therapy was administrated as second-line chemotherapy. After 1 course, weekly PTX has been continued for gr 3 proteinuria and the ascites disappeared after 4 courses. This successful case might indicate that it was important for patients with gr 3 proteinuria as adverse event to consider discontinuance of RAM and continuation of PTX according to the proper usage guide of RAM.

Mucinous cystadenoma of the appendix is a rare condition that develops as a result of proliferation of mucin-secreting cells in an occluded appendix. Mucinous cystadenoma of the appendix presenting as an umbilical hernia is a rare clinical entity. The most common causes of this condition are known to be ascites, hepatitis and cirrhosis; however, the patient in the present study, was diagnosed as hepatitis- and cirrhosis-negative, with no history of chronic coughing or constipation. The aim of the present study was to report a rare case of mucinous cystadenoma of the appendix presenting as an umbilical hernia in a 66-year-old female patient. The patient had a 6-month history of a reducible mass in the umbilical region and was diagnosed with umbilical hernia. Computed tomography and ultrasonography were performed and revealed massive ascites. Ultimately, a laparoscopic appendectomy was performed and borderline mucinous appendiceal cystadenoma of low malignant potential was confirmed. In addition, the present study discussed the association between mucinous cystadenoma of the appendix and umbilical hernia, as well as the diagnostic process and treatment strategies.

To study the protective effect of polysaccharides from corn silk (PCS) against cyclophosphamide (CTX) induced host damages in mice bearing H22 tumors. The ascitic and solid tumor bearing mice model were established to investigate the anti-tumor effects of different dose of PCS (100, 200 and 300 mg/kg). The effects of PCS alone and with combination of CTX on tumor weight, survival time, thymus and spleen index, white blood cell, nucleated cell of marrow, serum ALT and AST level were tested. The high-dose PCS (300 mg/kg) had significant inhibitory effects on tumor. After combination with CTX, the tumor inhibitory ratio was enhanced to 68.71%, the survival time of tumor-burdened ascites tumor mice was significantly prolonged to 72.07% compared with CTX group. The Q value of combination group was 0.997. Thymus and spleen index, white blood cell, nucleated cell of marrow decreased by CTX were ameliorated significantly. The level of ALT and AST increased by CTX were reduced by combination with PCS. PCS has a potent inhibitory effect on the growth of implanted H22 tumors in mice and has a synergetic effect and an attenuated toxic effect in combination with CTX.

Seventy-three abdominopelvic contrast-enhanced CT scans obtained in 60 patients with peritoneal tumor spread were reviewed retrospectively to determine the CT signs of peritoneal malignancy. Ascites was present in 54 studies (74%) and was the most common CT finding. Loculation of the fluid occurred in 25 (46%) of these. In nine (17%) of the 54, a new finding, absence of cul-de-sac fluid in the presence of generalized ascites, was noted. Parietal peritoneal thickening with contrast enhancement of the peritoneum, making the peritoneum visible as a thin line along the abdominal wall, was present in 45 (62%) of studies. This is believed to represent confluent peritoneal metastases. Small-bowel involvement was present in half of the cases (wall thickening and irregularity with or without obstruction). Tumor involvement of the omentum was visible as soft-tissue permeation of fat, enhancing nodules, and/or an omental cake. Of the 26 patients without a previously known malignancy, identification of the primary tumor in addition to peritoneal carcinomatosis was possible in 13 (50%). Appreciation of the spectrum of CT findings in peritoneal carcinomatosis is essential for accurate evaluation of scans in patients with abdominopelvic malignancies.

To evaluate whether prenatal diagnosis of intestinal midgut volvulus (a rare condition due to the small bowel loops twisting) can improve the prognosis of the newborns. In our Prenatal Diagnosis Center, eight cases of intestinal volvulus observed between 2007 and 2014 were retrospectively considered. Ultrasonographic signs can be direct and specific (whirlpool sign, coffee bean sign) or indirect and non-specific (abdominal mass, dilated bowel loops, pseudocysts, ascites, polyhydramnios). Prenatal diagnosis was performed at 20-34 weeks of gestation. All newborns were exposed to an emergency surgery: the major complication was due to cystic fibrosis. An early suspicion of intestinal volvulus allows the clinician to refer the patient to a tertiary center so to confirm the diagnosis and perform an appropriate follow-up in order to identify the proper time of delivery. The prognosis of the babies with prenatal intestinal volvulus depends on the length of the segment involved, on the level of intestinal obstruction, on the presence of meconium peritonitis and on the gestational age at birth. Our experience, according with the literature, suggests that ascites and absence of abdominal peristalsis are ultrasonographic signs that, in the third trimester of pregnancy, correctly lead to an immediate delivery intervention.

Development of Safe and Potent Oil-in-Water Emulsion of Paclitaxel to Treat Peritoneal Dissemination.

PubMed

2017-04-01

To develop a safer and more potent paclitaxel (PTX) formulation, we prepared various oil-in-water emulsions by using egg phosphatidylcholine, Tween 80, and a mixture of triglycerides with different fatty acid chain lengths as the cosurfactant, surfactant, and oil phase component, respectively. The mean particle diameters of the PTX-emulsions prepared were around 100 nm. The PTX-emulsions did not provoke histamine release from rat mast cells and did not show any significant hemolytic activity, suggesting that PTX-emulsions are biocompatible. In vivo antitumor activity after single intraperitoneal injection of PTX-emulsions to ascites tumor-bearing mice revealed that the formulation containing tricaproin and triacetin (3:1, wt/wt, PTX-emulsion B) significantly prolonged the survival time and suppressed the accumulation of ascites fluid. Two distinct in vitro release studies showed that the release of PTX from emulsion B was significantly faster than those from other preparations. These results indicate that the adequately sustained PTX release would lead to potent in vivo antitumor activity and that PTX-emulsion B would offer an alternative approach to treat peritoneal dissemination.

In the present study, active fractions of the methanolic extract of Xanthium strumarium (XS) showing potent cytotoxicity were determined using microculture tetrazolium (MTT) and sulforhodamine B (SRB) assays in selected cancer cell lines. The active fractions viz., chloroform soluble fraction of root (CEXSR), hexane soluble fraction of leaf (HEXSL), hexane soluble fraction of fruits (HEXSF) and chloroform soluble fraction of fruits (CEXSF) of XS were tested in transplantable animal tumor models for their antitumor potential. Dalton's ascitic lymphoma (DLA) cells were used to induce solid and liquid (ascites) tumor in mice. The tumor bearing animals were treated with active fractions at two dose levels (100 and 200 mg/kg). The antitumor activities of the active fractions in tumor bearing animals were monitored with parameters such as body weight and increase in life-span as well as biochemical and hematological modalities (in the case of liquid tumor). Tumor incidence and tumor volume were the parameters monitored in the case of the solid tumor model. The results were analyzed by one-way ANOVA followed by Tukey's post hoc test. The extracts were found to increase the life-span of tumor bearing animals and restore the altered hematological and biochemical parameters significantly.

An entire, female, mixed-breed cat of unknown age was presented with a 6-week history of lethargy, anorexia and vomiting. There was an increase in the number of white blood cells in the blood, including neutrophils and eosinophils; moderate anaemia; ascites; and possible mesenteric peritonitis. Exploratory laparotomy revealed firm, multifocal small nodules in the mesentery. As the nodules were surgically unresectable, they were biopsied. Histologically, the nodules were composed of thin trabeculae of dense collagen fibres mixed with plump fibroblasts and numerous eosinophils, consistent with feline gastrointestinal eosinophilic sclerosing fibroplasia. Bacteria were not detected on histological examination of the nodules and cytology of the ascites. Remission of disease occurred following treatment with prednisolone and ciclosporin A for 22 days and antibiotics for 40 days. After remission, ciclosporin A was administered for 236 days and then discontinued. Eosinophilia also resolved after treatment with ciclosporin A. The cat is still alive and in good condition on day 689. This report describes what may be an atypical case of feline gastrointestinal eosinophilic sclerosing fibroplasia, lacking involvement of the gastrointestinal tract, and was apparently cured by treatment that involved ciclosporin A. © 2018 British Small Animal Veterinary Association.

1994-05-01

During the period April 1991 to March 1992, data concerning the condemnation rate of standard, vegetarian, and free-range chickens were collected and summarized from one federally inspected abattoir in Ontario. The purpose of this study was to discuss the effects of diet, management, and breed of chickens on pathological lesions, ensuing condemnation rates, and consequent losses to the growers and the poultry industry. The data collected at this abattoir revealed that vegetarian chickens showed a higher condemnation rate (5.23%) for disease and nondisease conditions compared with standard (1.48%) and free-range (0.94%) chickens. Free-range chickens were approximately two weeks older than vegetarian and standard chickens at the time of slaughter. The most common causes of condemnation in vegetarian chickens was cellulitis (1.18%), followed by ascites (0.77%). Ascites and cellulitis (0.26% both) were also the most common causes of condemnation in standard chickens. Cyanosis (0.21%) and mutilation (0.17%) represented the highest rate of condemnation in free-range chickens. The low rate of pathological lesions in free-range chickens is a positive trend in poultry disease management.

Electrolyte and Acid-Base Disturbances in End-Stage Liver Disease: A Physiopathological Approach.

2017-08-01

Electrolyte and acid-base disturbances are frequent in patients with end-stage liver disease; the underlying physiopathological mechanisms are often complex and represent a diagnostic and therapeutic challenge to the physician. Usually, these disorders do not develop in compensated cirrhotic patients, but with the onset of the classic complications of cirrhosis such as ascites, renal failure, spontaneous bacterial peritonitis and variceal bleeding, multiple electrolyte, and acid-base disturbances emerge. Hyponatremia parallels ascites formation and is a well-known trigger of hepatic encephalopathy; its management in this particular population poses a risky challenge due to the high susceptibility of cirrhotic patients to osmotic demyelination. Hypokalemia is common in the setting of cirrhosis: multiple potassium wasting mechanisms both inherent to the disease and resulting from its management make these patients particularly susceptible to potassium depletion even in the setting of normokalemia. Acid-base disturbances range from classical respiratory alkalosis to high anion gap metabolic acidosis, almost comprising the full acid-base spectrum. Because most electrolyte and acid-base disturbances are managed in terms of their underlying trigger factors, a systematic physiopathological approach to their diagnosis and treatment is required.

Umbilical hernia alloplastic dual-mesh treatment in cirrhotic patients.

Abdominal wall hernias represent a pathology with an impressive prevalence among the population of patients with cirrhosis complicated by ascites. The aggressive surgical approach of umbilical hernia for patients with cirrhotic background remains a controversial problem, accompanied by anesthetic and surgical risk. Its indication remains fully justified in case of severe symptoms or life threatening complications: strangulation, incarceration, evisceration. This article evaluates results obtained by using dual-mesh alloplastic materials for surgical treatment of umbilical hernias affecting cirrhotic patients with incipient liver injury. Our lot consists of twelve patients with ages between 45 and 65 years, diagnosed with hepatic cirrhosis, without other associated comorbidities. All patients were admitted for strangulated umbilical hernia. Among the analyzed lot, no decease was encountered, the morbidity being limited to two cases of parietal suppuration, solved conservatively, without the mesh removal. There were no ascitic fistulas. No recurrences were registered for a 12 months tracking period. The presence of cirrhosis implies a high anesthetic and surgical risk, the intervention being grafted by a substantial increase of mortality and morbidity in an emergency setting. The development of new alloplastic materials, together with the modern anesthetic techniques, allows superior results for patients with incipient hepatic injury.

Desmoplastic small round cell tumor (DSRCT) is a rare malignant sarcoma with poor prognosis due to lack of effective treatments. Apatinib is a new potent oral small-molecule tyrosine kinase inhibitor, and targets the intracellular domain of vascular endothelial growth factor receptor 2 (VEGFR-2). In this study, we presented a case of intra-abdominal DSRCT which was effectively treated by apatinib. A 32-year-old man was admitted due to increasing urination frequency and palpable mass in right lower abdomen for 2 months. The mass was resected and diagnosed DSRCT. The patient refused chemotherapy and radiotherapy,and used Chinese medicine only. Six months after the surgery, the patient re-hospitalized due to growing abdominal mass and ascites. Intraperitoneal cisplatin treatment showed little effect. Apatinib was then recommended. Apatinib revealed outstanding effect on reducing mass size and ascites during 2-month treatment. Apatinib therapy continued for additional 2 months, and the patient was in good condition. The only toxicity was hand-food syndrome, which was controllable and well tolerated. It is the first report that apatinib is effective on DSRCT. This report may provide an additional option for the treatment of metastatic DSRCT.

The disease produced by feeding chickens and ducks a commercial poultry feed containing heliotrine and lasiocarpine, pyrrolizidine alkaloids of Heliotropium europaeum, is described. Illthrift, ascites and degenerative lesions in the liver were the major findings. Similar lesions occurred in chickens fed a diet containing H. europaeum. The source of the alkaloids in commercial poultry feed was probably the seeds of H. europaeum harvested with wheat.

A 10-yr-old, male brown bear ( Ursus arctos ) from Bursa Zoo in Turkey died without any apparent signs. Severe purulent pericarditis and myocarditis with mild ascites, lung edema, and moderate liver congestion were observed during necropsy. Microscopically, there were severe neutrophilic infiltrations in the myocardium and thoracic lymph nodes. A member of the Streptococcus bovis - Streptococcus equinus complex (SBSEC) was isolated and identified phenotypically.

Purpose To assess the determinants of technical failure of magnetic resonance (MR) elastography of the liver in a large single-center study. Materials and Methods This retrospective study was approved by the institutional review board. Seven hundred eighty-one MR elastography examinations performed in 691 consecutive patients (mean age, 58 years; male patients, 434 [62.8%]) in a single center between June 2013 and August 2014 were retrospectively evaluated. MR elastography was performed at 3.0 T (n = 443) or 1.5 T (n = 338) by using a gradient-recalled-echo pulse sequence. MR elastography and anatomic image analysis were performed by two observers. Additional observers measured liver T2* and fat fraction. Technical failure was defined as no pixel value with a confidence index higher than 95% and/or no apparent shear waves imaged. Logistic regression analysis was performed to assess potential predictive factors of technical failure of MR elastography. Results The technical failure rate of MR elastography at 1.5 T was 3.5% (12 of 338), while it was higher, 15.3% (68 of 443), at 3.0 T. On the basis of univariate analysis, body mass index, liver iron deposition, massive ascites, use of 3.0 T, presence of cirrhosis, and alcoholic liver disease were all significantly associated with failure of MR elastography (P < .004); but on the basis of multivariable analysis, only body mass index, liver iron deposition, massive ascites, and use of 3.0 T were significantly associated with failure of MR elastography (P < .004). Conclusion The technical failure rate of MR elastography with a gradient-recalled-echo pulse sequence was low at 1.5 T but substantially higher at 3.0 T. Massive ascites, iron deposition, and high body mass index were additional independent factors associated with failure of MR elastography of the liver with a two-dimensional gradient-recalled-echo pulse sequence. © RSNA, 2017.

To test the hypothesis that same-day discharge of selected transarterial chemoembolization patients would not increase 30-day readmission rate compared with overnight observation. With institutional review board approval, 193 hepatocellular carcinoma patients who underwent transarterial chemoembolization from July 2013 to June 2016 were reviewed. Treatment was conventional/lipiodol transarterial chemoembolization with 50 mg doxorubicin/10 mg mitomycin-c/particles or drug-eluting embolics transarterial chemoembolization with 50-75 mg doxorubicin/vial. At 3 hours, patients tolerating oral intake and not requiring intravenous analgesics were considered for discharge. The primary outcome measure was 30-day readmission for observation versus discharge using chi-squared (χ 2 ) analysis. The secondary aim was to identify baseline or treatment variables independently associated with readmission, including Child-Pugh class, medically managed encephalopathy or ascites, patient age (<65 vs ≥65), tumor number (1 or >1), and level of embolization (segmental vs lobar). Patients underwent 261 transarterial chemoembolization procedures. The 30-day readmission rate was not significantly different between observed patients (n = 179, 9.0%) and discharged patients (n = 82, 13.8%; P = .33). Readmission was not related to the selected agent (conventional/lipiodol-transarterial chemoembolization, 11.0% vs drug-eluting embolics transarterial chemoembolization, 7.5%; P = .36). Baseline variables associated with readmission were Child-Pugh B/C (χ2 = 7.9, P < .01), history of encephalopathy (χ2 = 15.4, P < 0.01), and ascites (χ2 = 4.4, P < .05). Patient age (<65 vs ≥65), tumor number (1 vs >1), and level of embolization (segmental vs lobar) were not predictive of readmission (all P > .05). Same-day discharge after transarterial chemoembolization does not increase the risk of 30-day readmission. Child-Pugh B/C patients, as well as those with ascites or encephalopathy, have the

Large-volume paracentesis (LVP) can be time and labor intensive depending on the amount of ascites removed and the method of drainage. Wall suction has been adopted as the preferred method of drainage at many centers, though the safety and benefits of this technique have not been formally evaluated. The primary objective of this study was to define the cost and time savings of wall suction over the traditional glass vacuum bottle method for ascites drainage. The secondary objective was to compare the safety profile and patient satisfaction using these two techniques. We conducted a randomized, controlled pilot study of the wall suction versus vacuum bottle methods for LVP in hospitalized patients. All LVPs were performed under ultrasound guidance by a single proceduralist. Patients with at least 4 liters removed received 25% intravenous albumin, 8 g/liter fluid removed. Demographic, clinical characteristics, and procedure details were recorded. Laboratory and hemodynamic data were recorded for 24 h prior to and 24-48 h post LVP. An electronic chart review was conducted to evaluate procedure-related complications. Data were compared using Fisher's exact test, t test, or Mann-Whitney U test. Thirty-four patients were randomized to wall suction at 200 mmHg (n = 17) or glass vacuum bottle drainage (n = 17). Wall suction was significantly faster and less costly than vacuum bottle drainage (7 versus 15 min, p = 0.002; $4.59 versus $12.73, p < 0.001). There were no differences in outcomes at 24 and 48 h post LVP, or at 60-day follow up. Performing LVP using wall suction resulted in significantly shorter procedure time and supply cost savings. There were no differences in outcomes between the groups, suggesting equivalent safety, though larger studies powered to detect small differences are needed. Given its efficiency, convenience, and cost effectiveness, wall suction may be a superior method of ascites drainage for LVP.
