    Hepatobiliary scintigraphy has been recognized as a useful diagnostic tool in detecting the presence and site of bile leaks. The authors report a case of bile ascites secondary to a postsurgical biliary leak, the scintigraphic findings in bile ascites, and the potential use of paracentesis, in combination with hepatobiliary scintigraphy, in confirming the presence of bile ascites and a bile leak

    A method was developed dor determination of aldosterone in ascitic fluid. Elevated aldosterone levels in plasma and ascitic fluid of 10 patients with advanced cirrhosis of the liver were recorded, as compared to the plasma levels in normal subjects. Elevated aldosterone levels in these patients was of definite importance for the choice of adequate diuretic drug, since the effectiveness of diuretic treatment largely depended on renin activity and aldosterone level.

    Objective: To determine the frequency and compare the culture yield of bacterial isolation by conventional and blood culture BACTEC bottle techniques in cirrhotic patients with spontaneous bacterial peritonitis (SBP). Study Design: Cross-sectional comparative study. Place and Duration of Study: Pathology Department, Bannu Medical College, Bannu, KPK, from January 2012 to December 2013. Methodology: Paracentesis of 20 ml of ascitic fluid tapped from cirrhotic patients with SBP was carried out by a single technologist. The analysis included differential leukocyte count (DLC), while 5 ml each of the fluid was inoculated into conventional culture media and BACTEC blood culture bottle. All the data were analysed on (SPSS) version 16 to determine frequencies with percentages and mean values with standard deviation. Chi-square test was used for comparing the yield of conventional and blood culture bottle methods. P-value was considered significant if < 0.05. Results: In 105 cases of ascitic fluid analyses, 27 (25.72 percent) had positive ascitic fluid culture whereas 78 (74.28 percent) had negative ascitic fluid culture. Ascitic fluid culture was positive in 6 cases by conventional culture media and in 27 cases by BACTEC culture bottle media (p < 0.001). Bacterial isolation was obtained by both culture methods in 6 cases (p < 0.001). Conclusion: Direct bedside inoculation of ascitic fluid by BACTEC culture bottle method has better yield as compared to conventional culture method. (author)

    Technetium-99m phytate colloids formed in vitro and in vivo were examined as radioindicators for estimation of the volume of third-space fluid in an ovarian ascites model using C3HeB/FeJ mice. In double-label experiments, the accuracy of the colloids for dilution analysis was found to be equal or superior to that of I-125 HSA. Sampling times 3 to 5 min after intraperitoneal administration were found to produce the best volume estimates. Four needle-stopcock assemblies inserted sequentially into the quadrants of the peritoneal cavity were used for administration and sampling of the radioindicators. The stopcocks could be closed to prevent leakage of ascitic fluid during the procedure. In contrast to radiolabeled albumin, Tc-99m phytate colloids have clinical use for simultaneous imaging of radiotracer migration to assess potential occlusion of diaphragmatic lymphatics by neoplastic cells, and for dilution analysis to estimate volume of ascitic fluid

    Objective: To investigate the diagnostic value of determination of serum and ascitic fluid AFP, CEA and CA125 contents for differentiating benign from malignant ascites. Methods: Serum and ascitic fluid contents of the three tumor markers were measured with RIA in 86 patients with ascites due to various causes. Results: The serum and ascitic fluid AFP, CEA and CA125 levels in patients with malignant ascites were very significantly higher than those in patients with benign ascites (p<0.01). For differentiation of benign (mainly T.B and liver cirrhosis) from malignant ascites, CA125≥500 IU/ml and AFP≥300 ng/ml could be taken as the critical value with high specificity and accuracy. Conclusion: Determinations of the three tumor markers levels in serum and ascitic fluid were of high value for differential diagnosis of the etiology of ascites

    Malignant ascites is a sign of peritoneal seeding, which is one of the most frequent forms of incurable distant metastasis. Because the development of malignant ascites is associated with an extremely poor prognosis, determining whether it resulted from peritoneal seeding has critical clinical implications in diagnosis, choice of treatment, and active surveillance. At present, the molecular characterizations of malignant ascites are especially limited in case of gastric cancer. We aimed to identify malignant ascites-specific proteins that may contribute to the development of alternative methods for diagnosis and therapeutic monitoring and also increase our understanding of the pathophysiology of peritoneal seeding. First, comprehensive proteomic strategies were employed to construct an in-depth proteome of ascitic fluids. Label-free quantitative proteomic analysis was subsequently performed to identify candidates that can differentiate between malignant ascitic fluilds of gastric cancer patients from benign ascitic fluids. Finally, two candidate proteins were verified by ELISA in 84 samples with gastric cancer or liver cirrhosis. Comprehensive proteome profiling resulted in the identification of 5347 ascites proteins. Using label-free quantification, we identified 299 proteins that were differentially expressed in ascitic fluids between liver cirrhosis and stage IV gastric cancer patients. In addition, we identified 645 proteins that were significantly expressed in ascitic fluids between liver cirrhosis and gastric cancer patients with peritoneal seeding. Finally, Gastriscin and Periostin that can distinguish malignant ascites from benign ascites were verified by ELISA. This study identified and verified protein markers that can distinguish malignant ascites with or without peritoneal seeding from benign ascites. Consequently, our results could be a significant resource for gastric cancer research and biomarker discovery in the diagnosis of malignant ascites

    BACKGROUND/AIMS: To determine dynamics of albumin in plasma and ascitic fluid of patients with cirrhosis. METHODS: Forty-seven patients were classified in four groups: I--patients without fluid retention; II--patients with ascites not resistant to subsequent diuretic treatment; III......--recompensated patients during diuretic treatment; and IV--patients with diuretic-resistant ascites. Transvascular and transperitoneal albumin transports were quantified by 131I-/125I-labelled human albumin. RESULTS: TER(P) (i.e. the fraction of intravascular albumin (IVM) passing from plasma into the interstitial space...... per hour) was increased in all groups. In group IV patients the transport rate of albumin from plasma into the ascitic fluid (TER(PA)) was significantly higher than the transport rate from the ascitic fluid back into the plasma: TER(AP) (0.45 vs. 0.26% IVM/h, P

    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.

    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.

    Full Text Available A patient with alcoholic cirrhosis of the liver, portal hypertension with hepatic encephalopathy and spontaneous bacterial peritonitis (SBP was admitted in an obtunded condition. Attempts at delineating the aetiology of the SBP using conventional cultures as well as automated systems were not successful. The use of non-anionic surfactant agents such as Tween 80-incorporated blood agar and Triton X treatment of the specimens facilitated the growth of Klebsiella pneumoniae from the ascitic fluid, which otherwise would have been concluded to represent culture-negative neutrocytic ascites. Thus, the use of the aforementioned agents could be explored in elucidating the aetiology of body cavity infections when conventional methods fail.

    Full Text Available Serum and ascitic fluid superoxide dismutase (SOD and malondialdehyde (MDA levels were measured in 43 patients with cirrhosis and in a 10 healthy control group. Compensated cirrhotic patients had no clinically detectable ascites, but decompensated patients had massive ascites. Cirrhotic patients were divided into three groups: patients with compensated cirrhosis (n = 16, patients with decompensated cirrhosis with Spontaneous bacterial peritonitis (SBP (n = 14, and patients with decompensated cirrhosis without SBP (n = 13. All cirrhotic patients in the experimental group had significantly higher serum SOD (p 0.05. These results suggest that the increase in serum SOD and MDA levels are not related to the presence of SBP and the status of liver cirrhosis. To sum up, clarifying the impact of increased serum SOD and MDA levels in cirrhotic patients needs further investigation.

    Transthyretin (TTR), a traditional biomarker for nutritional and inflammatory status exists in different molecular variants of yet unknown importance. A truncated form of TTR has recently been described to be part of a set of biomarkers for the diagnosis of ovarian cancer. The main aim of the study was therefore to characterize differences in microheterogeneity between ascitic fluid and plasma of women affected with ovarian cancer and to evaluate the tumor site as the possible source of TTR. Subjects were 48 women with primary invasive epithelial ovarian cancer or recurrent ovarian carcinoma. The control group consisted of 20 postmenopausal women. TTR and retinol-binding protein (RBP) levels were measured by enzyme-linked immunoassay (ELISA) and C-reactive protein (CRP) levels by a high-sensitivity latex particle turbidimetric assay. The molecular heterogeneity of TTR was analysed using immunoprecipitation and matrix-associated laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Presence of TTR in tumor tissue was determined with indirect peroxidase immunostaining. TTR and RBP (μg/ml) levels in serum were 148.5 ± 96.7 and 22.5 ± 14.8 in affected women compared to 363.3 ± 105.5 and 55.8 ± 9.3 in healthy postmenopausal women (p < 0.01). In ascitic fluid, levels were 1.02 ± 0.24 and 4.63 ± 1.57 μg/ml, respectively. The mean levels of TTR and RBP in serum showed a tendency to decrease with the severity of the disease and were lower in affected women whose CRP levels were > 40 mg/ml (p = 0.08 for TTR; p < 0.05 for RBP). No differences in TTR microheterogeneity were observed between TTR isolated from serum of affected and healthy women or from ascitic fluid. TTR occurred rather consistently in four variants. Mass signals were at 13758 ± 7, 13876 ± 13 (greatest intensity), 13924 ± 21 and 14062 ± 24 Da, representing native, S-cysteinylated, S-cysteinglycinylated and glutathionylated TTR, respectively.

    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.

    Full Text Available Cirrhotic patients (23 with alcoholic cirrhosis, 5 with posthepatitic cirrhosis and 2 with cryptogenic cirrhosis with ascites and portal hypertension were studied and divided into two groups corresponding to high or low risk to develop spontaneous bacterial peritonitis (SBP related to the concentration of total protein in the ascitic fluid (A-TP: group I (high risk: A-TP£1.5 g/dl and group II (low risk: A-TP>1.5 g/dl. Fibronectin (FN, C3 and C4 concentrations were measured by radial immunodiffusion while total protein was measured by the biuret method. The mean values (group I vs group II of C3 (12.59 ± 4.72 vs 24.53 ± 15.58 mg/dl, C4 (4.26 ± 3.87 vs 7.26 ± 4.14 mg/dl and FN (50.47 ± 12.49 vs 75.89 ± 24.70 mg/dl in the ascitic fluid were significantly lower (P<0.05 in the group considered to be at high risk for SBP. No significant difference was observed in the plasma/ascites fibronectin ratio (3.91 ± 1.21 vs 3.80 ± 1.26 or gradient (131.46 ± 64.01 vs 196.96 ± 57.38 between groups. Fibronectin in ascites was significantly correlated to C3 (r = 0.76, C4 (r = 0.58, total protein (r = 0.73 and plasma FN (r = 0.58 (P<0.05. The data suggest that the FN concentration in ascites is related to the opsonic capacity of this fluid, and that its concentration in the ascitic fluid may be a biochemical risk factor indicator for the development of spontaneous bacterial peritonitis

    In this dissertation, the glycolytic nature of the Ehrlich ascites tumor (EAT) cell is disclosed both in vivo and in vitro by experiments challenging it with glucose. It is demonstrated that EAT cells can cause the extracellular pH to drop to values sufficiently acidic so as to inhibit EAT glycolysis. However, the extracellular fluid or the Ascites Supernatant Fluid (ASF) reduced the extent to which the pH dropped during EAT cell glycolysis. A comparison of the activities of the sera from tumor-bearing mice and normal mice revealed that the serumfrom the tumor-bearing mice reduced the pH fall generated by the EAT cell in the same way as did ASF; normal mouse serum had no such effect. The metabolic pathways utilized during glucose catabolism were examined by radio-respirometry and the results demonstrated that the high percentage of the glucose conversion to lactate occurred because of partial blockade of the TCA cycle. The databolism of glutamine, glutamic acid, asparagine, aspartic acid, and alanine was enhanced by ASF as determined by measuring 14 CO 2 from 14 C-labelled amino acids, with glutamine catabolism enhanced about three-fold. Fractionation experiments revealed that ASF contained a factor(s) responsible for this enhancement that had a molecular weight greater than 300,000 daltons and was heat-labile

    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.

    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.

    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 (pencephalopathy. In patients with severe hepatic encephalopathy serotonin concentration in blood is decreased which can affect some clinical manifestation of this disease.

    This cross sectional study was carried out in the department of gastroenterology, BIRDEM, Dhaka from January 2010 to May 2011 to determine the role of ascitic fluid ADA and serum CA-125 in the diagnosis of clinically suspected tubercular peritonitis. 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.

    Full Text Available Abstract Background Ascitic fluid infection (AFI in cirrhotic patients has a high morbidity and mortality. It has two variants namely, spontaneous bacterial peritonitis (SBP and culture negative neutrocytic ascites (CNNA. The aim of this study was to determine the outcome in cirrhotic patients with culture positive (SBP and culture negative neutrocytic ascites. Methods We analyzed 675 consecutive hepatitis B and/or C related cirrhosis patients with ascites admitted in our hospital from November 2005 to December 2007. Of these, 187 patients had AFI; clinical and laboratory parameters of these patients including causes of cirrhosis, Child Turcotte Pugh (CTP score were recorded. Results Out of 187 patients with AFI, 44 (23.5% had SBP while 143 (76.4% had CNNA. Hepatitis C virus (HCV infection was the most common cause of cirrhosis in 139 (74.3% patients. Patients with SBP had high CTP score as compared to CNNA (12.52 ± 1.45 vs. 11.44 ± 1.66; p 9/L as compared to CNNA (132 ± 91 × 109/L, p = 0.005. We found a high creatinine (mg/dl (1.95 ± 1.0 vs. 1.44 ± 0.85, (p = 0.003 and high prothrombin time (PT in seconds (24.8 ± 6.6 vs. 22.4 ± 7.2 (p = 0.04 in SBP as compared to CNNA. More patients with SBP (14/44; 31.8% had blood culture positivity as compare to CNNA (14/143; 9.8%, p = 0.002. Escherichia. Coli was the commonest organism in blood culture in 15/28 (53.5% patients. SBP group had a higher mortality (11/44; 25% as compared to CNNA (12/143; 8.4%, p = 0.003. On multiple logistic regression analysis, creatinine >1.1 mg/dl and positive blood culture were the independent predictors of mortality in patients with SBP. Conclusion Patients with SBP have a higher mortality than CNNA. Independent predictors of mortality in SBP are raised serum creatinine and a positive blood culture.

    Objective: To study the clinical usefulness of combined detection of tumor markers in effusion fluid in patients with malignant pleural effusion or ascites. Methods: Combined detection of six tumor markers (CA125, CA50, CA15-3, CYFRA21-1, βHCG, HCG) in effusion fluid was performed in 92 patients with malignant pleural effusion and 78 patients with malignant ascites as well as 100 control benign specimens. These tumor markers were examined with CLIA, except CA50, which was examined with RIA. Exfoliative cytology was also examined in the malignant specimens. Results: The positive rate of these markers was highest with CA125, followed by CA50, CA15-3, CYFRA21-1, βHCG and HCG in order. βHCG and HCG, though with quite low positive rate, were still useful markers due to the almost zero false-positive rate, i.e. very high specificity. For combined determination of two markers, CA15 + CYFRA21-1 or CA125 + CA50 would result in the highest positive rate. For highly suspected but undetermined cases, the following criteria for malignancy would be helpful: (1) two or more positive among CA125, CA50, CA15-3, CYFRA21-1 (2) One of the four CAs positive + either βHCG or HCG (3) Both βHCG and HCG positive. Tumor markers positiveness would be supplementary to doubtful cytological studies. Conclusion: Combined detection of tumor markers in effusion fluid would be very helpful for diagnosis of malignancy.

As previously substantiated in patients with cirrhosis, the ascitic fluid/plasma concentration ratio (R) of a protein is proportional to the transport rate from blood to lymph (ascitic fluid). Mean Ralb = 0.28 and RIgG = 0.29 were identical......, but significantly higher than, RIgM = 0.18 (P less than 0.01). Ralb was directly correlated to RIgG (r = 0.97, P less than 0.001) and to RIgM (r = 0.78, P less than 0.005). Mean RIgG/Ralb = 1.03, which expresses the relative flux rates between IgG and albumin, was significantly above the ratio between the free...... diffusion coefficients (DIgG/Dalb = 0.64, P less than 0.01). Mean RIgM/Ralb = 0.61 was significantly above DIgM/Dalb = 0.39 (P less than 0.05) and significantly below unity (P less than 0.01). The results are best explained by filtration as the dominant mechanism of the liver blood-lymph (ascitic fluid...

    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

In the current study, the feasibility of preparing bile salt/phospholipid MM precursor (preMM pellets with high oral bioavailability, using fluid-bed coating technology, was examined. In this study, fenofibrate (FB and sodium deoxycholate (SDC were used as the model drug and the bile salt, respectively. To prepare the MMs and to serve as the micellular carrier, a weight ratio of 4:6 was selected for the sodium deoxycholate/phospholipids based on the ternary phase diagram. Polyethylene glycol (PEG 6000 was selected as the dispersion matrix for precipitation of the MMs onto pellets, since it can enhance the solubilizing ability of the MMs. Coating of the MMs onto the pellets using the fluid-bed coating technology was efficient and the pellets were spherical and intact. MMs could be easily reconstituted from preMM pellets in water. Although they existed in a crystalline state in the preMM pellets, FB could be encapsulated into the reconstituted MMs, and the MMs were redispersed better than solid dispersion pellets (FB:PEG = 1:3 and Lipanthyl®. The redispersibility of the preMM pellets increased with the increase of the FB/PEG/micellar carrier. PreMM pellets with a FB:PEG:micellar carrier ratio of 1:1.5:1.5 showed 284% and 145% bioavailability relative to Lipanthyl® and solid dispersion pellets (FB:PEG = 1:3, respectively. Fluid

    Objective: To investigate the chinical value of effusion fluid HCG and β-HCG content determination in the differentiation of malignant from benign disorders. Methods: Fluid contents of HCG and β-HCG were determined with RIA in (1) 50 cases with benign pleural effusion. (2) 50 eases with benign ascites. (3) 79 cases with malignant pleural effusion. (4) 78 eases with malignant ascites and (5) 13 cases with malignant pericardial effusion. Results: (1) No false positive cases were present among the 100 benign eases, suggesting a high specificity with HCG and β-HCG determination. (2) Positive rate of HCG in malignancy: malignant pleural effusion, 55.64% (44/79), malignant ascites, 43.58% (34/76), malignant pericardial effusion 92.30% (12/13). (3) Positive rate of β-HCG in malignancy: malignant pleura[ effusion, 62.02% (49/79), malignant ascites, 66.66% (52/78), malignant pericardial effusion, 92.30% (12/13). (4) Coincidence of 91 eases of positive exfoliative cytology and tumor markers: HCG, 65.93% (60/91), β-HCG 73.62% (67/91), combined HCG and β-HCG, 47.25% (43/91). (5) In 79 eases with negative cytology, HCG was positive in 50 eases (63.29%) and β-HCG was positive in 60 cases (75.94%). A remarkable event was: both HCG and β-HCG were positive in 6 cases of malignant pericardial effusion with negative cytology. (6) In malignant pleural effusions, positive rate of HCG was much higher in the 14 eases with squamous cell carcinoma (78.57%, 11/14) than that in the 33 eases with adenocarcinoma (48.48%), 16/33) (P <0.05), therefore, HCG was the marker of choice in eases with effusion from squamous cell carcinoma. Conclusion: In the abscence of pregnancy, malignancy is highly probable with positive HCG or β-HCG in ascitic or pleural effusion fluid and the diagnosis is almost certain with combined positiveness.

    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.

  9. Four Cases of Chylous Ascites following Robotic Gynecologic Oncological Surgery

    Full Text Available Chylous ascites is an uncommon form of ascites characterized by milky-appearing fluid caused by blocked or disrupted lymph flow through chyle-transporting vessels. The most common causes of chylous ascites are therapeutic interventions and trauma. In this report, we present four cases of chylous ascites following robot-assisted surgery for endometrial staging and the treatment strategies that we used. After retroperitoneal lymph node dissection, leaving a drain is very useful in diagnosing chylous ascites and observing its resolution; furthermore, the use of octreotide in conjunction with TPN appears to be an efficient treatment modality for chylous ascites and should be considered before any invasive intervention.

    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.

  12. Evaluation of bile reflux in HIDA images based on fluid mechanics.

    We propose a new method to help physicians assess, using a hepatobiliary iminodiacetic acid scan image, whether or not there is bile reflux into the stomach. The degree of bile reflux is an important index for clinical diagnosis of stomach diseases. The proposed method applies image-processing technology combined with a hydrodynamic model to determine the extent of bile reflux or whether the duodenum is also folded above the stomach. This condition in 2D dynamic images suggests that bile refluxes into the stomach, when endoscopy shows no bile reflux. In this study, we used optical flow to analyze images from Tc99m-diisopropyl iminodiacetic acid cholescintigraphy (Tc99m-DISIDA) to ascertain the direction and velocity of bile passing through the pylorus. In clinical diagnoses, single photon emission computed tomography (SPECT) is the main clinical tool for evaluating functional images of hepatobiliary metabolism. Computed tomography (CT) shows anatomical images of the external contours of the stomach, liver, and biliary extent. By exploiting the functional fusion of the two kinds of medical image, physicians can obtain a more accurate diagnosis. We accordingly reconstructed 3D images from SPECT and CT to help physicians choose which cross sections to fuse with software and to help them more accurately diagnose the extent and quantity of bile reflux.

    The aim of the study was to assess pH, pO2 and pCO2 in peritoneal fluid. The study was conducted on a group of 22 dogs with symptoms of ascites. Group 1 consisted of 4 dogs with adenocarcinoma, group 2--of 6 dogs with glomerulonephritis, group 3 of 8 dogs with hepatic cirrhosis and group 4 of 4 dogs with bacterial peritonitis. An abdominal cavity puncture was performed in all dogs and the fluid was drawn into a heparinized syringe in order to assess pH, pO2 and pCO2 . The analysis of pH in the peritoneal fluid revealed statistically significant differences between group 4 and groups 1 (p=0.01), 2 (p=0.01), and 3 (p=0.01). The lowest pH value compared to the other studied groups was recorded in group 4. In group 4, the pO2 was the lowest compared to the other groups (group 1 p=0.01, group 2 p=0.01, group 3 p=0.01). The value of pCO2 was the highest in group 4 compared to groups 1, 2, and 3. The study found statistically significant differences in pH, pCO2 and pCO2 between group 4 (the group of dogs with bacterial peritonitis) and the other groups of dogs. This was probably linked to the pathogenesis of peritonitis. As a result of an inflammatory reaction within the peritoneal cavity, there is an increase in fibrin accumulations leading to a decreased oxygen supply causing the oxidative glucose metabolism to change into a non-oxidative glucose metabolism. This, in turn, causes a decrease in pH, acidosis, and a low oxidoreduction potential. It also impairs phagocytosis and activates proteolytic enzymes which create ideal conditions for the growth of anaerobic bacteria. The obtained results indicate that the pH, pO2 and pCO2 may be used to differentiate bacterial peritonitis from ascites of other etiologies.

    The leak of ascitic fluid from surgical incisions is thought to be associated with a very high mortality rate. There have been few reports, however, focusing on the clinical characteristics, management, or mortality rates of this condition. During a 10-year period, 18 patients with postoperative ascitic fluid leaks were treated. All patients had ascites before surgery and all had liver disease; in 13 of the 18 patients alcoholic liver disease was the cause of ascites. Ten of the 18 patients died (56%). Midline incisions were more often associated with recalcitrant leaks and fatal complications than were transverse incisions. Early consideration of fascial dehiscence and prompt repair is emphasized. The most effective predictor of survival was cessation of the leak.

    Full Text Available Background: There is a broad etiology for effusion eosinophilia that includes allergic, reactive, infectious, immune, neoplastic, and idiopathic causes. We report and describe the cytomorphologic findings of a rare case of eosinophilic ascites due to severe eosinophilic ileitis. Case Presentation: A 17-year-old male manifested acutely with eosinophilic ascites due to severe biopsy-proven subserosal eosinophilic ileitis. Isolated peritoneal fluid submitted for cytologic evaluation revealed that 65% eosinophils were present in a bloody background. The patient responded to corticosteroids, with complete resolution of his ascites. Conclusion: Eosinophilic gastroenteritis with subserosal involvement should be added to the list of causes for eosinophils in peritoneal fluid. The finding of eosinophilic ascites, with appropriate clinical and laboratory findings, may warrant the need to perform laparoscopic intestinal biopsies to confirm the diagnosis.

    Full Text Available Endemic to the southwestern parts of the United States, coccidioidomycosis, also known as “Valley Fever,” is a common fungal infection that primarily affects the lungs in both acute and chronic forms. Disseminated coccidioidomycosis is the most severe but very uncommon and usually occurs in immunocompromised individuals. It can affect the central nervous system, bones, joints, skin, and, very rarely, the abdomen. This is the first case report of a patient with coccidioidal dissemination to the peritoneum presenting as eosinophilic ascites (EA. A 27-year-old male presented with acute abdominal pain and distention from ascites. He had eosinophilia of 11.1% with negative testing for stool studies, HIV, and tuberculosis infection. Ascitic fluid exam was remarkable for low serum-ascites albumin gradient (SAAG, PMN count >250/mm3, and eosinophils of 62%. Abdominal imaging showed thickened small bowel and endoscopic testing negative for gastric and small bowel biopsies. He was treated empirically for spontaneous bacterial peritonitis, but no definitive diagnosis could be made until coccidioidal serology returned positive. We noted complete resolution of symptoms with oral fluconazole during outpatient follow-up. Disseminated coccidioidomycosis can present in an atypical fashion and may manifest as peritonitis with low SAAG EA. The finding of EA in an endemic area should raise the suspicion of coccidioidal dissemination.

    Full Text Available A 39-year-old man was referred to our hospital for the investigation of abdominal fluid collection. He was pointed out to have alcoholic chronic pancreatitis. Laboratory data showed inflammation and slightly elevated serum direct bilirubin and amylase. An abdominal computed tomography demonstrated huge fluid collection, multiple pancreatic pseudocysts and pancreatic calcification. The fluid showed a high level of amylase at 4,490 IU/l. Under the diagnosis of pancreatic ascites, endoscopic pancreatic stent insertion was attempted but was unsuccessful, so surgical treatment (Frey procedure and cystojejunostomy was performed. During the operation, a huge amount of fluid containing bile acid (amylase at 1,474 IU/l and bilirubin at 13.5 mg/dl was found to exist in the extraperitoneal space (over the peritoneum, but no ascites was found. His postoperative course was uneventful and he shows no recurrence of the fluid. Pancreatic ascites is thought to result from the disruption of the main pancreatic duct, the rupture of a pancreatic pseudocyst, or possibly leakage from an unknown site. In our extremely rare case, the pancreatic pseudocyst penetrated into the hepatoduodenal ligament with communication to the common bile duct, and the fluid flowed into the round ligament of the liver and next into the extraperitoneal space.

    Ascites can lead to many symptoms, and often occurs in patients with an end-stage malignancy such as ovarian, pancreatic, colonic, or gastric cancer. Intermittent ascites drainage is applied in these patients as a palliative measure. As frequent drainage is necessary, a subcutaneously tunnelled permanent ascites catheter is a good alternative for intermittent drainage. The patient can open - and then re-close - the catheter when abdominal pressure increases. We inserted 35 subcutaneously permanent ascites catheters in the course of the past 3.5 years in the Leiden University Medical Centre. The success rate was 100% and the complication risk was 2.9%. A subcutaneously tunnelled ascites catheter is an effective and safe palliative treatment for patients with end-stage malignant disease and suffering from ascites.

    Are bile acids (BA) and their respective subspecies present in human follicular fluid (FF) and do they relate to embryo quality in modified natural cycle IVF (MNC-IVF)? BA concentrations are 2-fold higher in follicular fluid than in serum and ursodeoxycholic acid (UDCA) derivatives were associated with development of top quality embryos on Day 3 after fertilization. Granulosa cells are capable of synthesizing BA, but a potential correlation with oocyte and embryo quality as well as information on the presence and role of BA subspecies in follicular fluid have yet to be investigated. Between January 2001 and June 2004, follicular fluid and serum samples were collected from 303 patients treated in a single academic centre that was involved in a multicentre cohort study on the effectiveness of MNC-IVF. Material from patients who underwent a first cycle of MNC-IVF was used. Serum was not stored from all patients, and the available material comprised 156 follicular fluid and 116 matching serum samples. Total BA and BA subspecies were measured in follicular fluid and in matching serum by enzymatic fluorimetric assay and liquid chromatography-mass spectrometry, respectively. The association of BA in follicular fluid with oocyte and embryo quality parameters, such as fertilization rate and cell number, presence of multinucleated blastomeres and percentage of fragmentation on Day 3, was analysed. Embryos with eight cells on Day 3 after oocyte retrieval were more likely to originate from follicles with a higher level of UDCA derivatives than those with fewer than eight cells (P IVF were used, which resulted in 14 samples only from women with an ongoing pregnancy, therefore further prospective studies are required to confirm the association of UDCA with IVF pregnancy outcomes. The inter-cycle variability of BA levels in follicular fluid within individuals has yet to be investigated. We checked for macroscopic signs of contamination of follicular fluid by blood but the

  6. Bile Formation and Secretion

    2014-01-01

    Bile is a unique and vital aqueous secretion of the liver that is formed by the hepatocyte and modified down stream by absorptive and secretory properties of the bile duct epithelium. Approximately 5% of bile consists of organic and inorganic solutes of considerable complexity. The bile-secretory unit consists of a canalicular network which is formed by the apical membrane of adjacent hepatocytes and sealed by tight junctions. The bile canaliculi (~1 μm in diameter) conduct the flow of bile countercurrent to the direction of portal blood flow and connect with the canal of Hering and bile ducts which progressively increase in diameter and complexity prior to the entry of bile into the gallbladder, common bile duct, and intestine. Canalicular bile secretion is determined by both bile salt-dependent and independent transport systems which are localized at the apical membrane of the hepatocyte and largely consist of a series of adenosine triphosphate-binding cassette transport proteins that function as export pumps for bile salts and other organic solutes. These transporters create osmotic gradients within the bile canalicular lumen that provide the driving force for movement of fluid into the lumen via aquaporins. Species vary with respect to the relative amounts of bile salt-dependent and independent canalicular flow and cholangiocyte secretion which is highly regulated by hormones, second messengers, and signal transduction pathways. Most determinants of bile secretion are now characterized at the molecular level in animal models and in man. Genetic mutations serve to illuminate many of their functions. PMID:23897680

    Full Text Available Analysis of ascitic fluid should help to identify and characterize malignant cells in gastrointestinal cancer. However, despite a high specificity, the sensitivity of traditional ascitic fluid cytology remains insufficient, at around 60%. Since 2004 the CellSearch® technology has shown its advantages in the detection of circulating tumor cells (CTCs in peripheral blood, which can perform an accurate diagnosis and molecular analysis at the same time. To our knowledge, no previous study has explored the potential utility of this technology for the detection and quantification of tumor cells in ascitic fluid samples. Herein we report a case of metastatic esophageal adenocarcinoma in a 70-year-old man presenting with dysphagia and a large amount of fluid in the peritoneal cavity. Analysis of a peripheral blood sample and ascites sample with the CellSearch® technology both revealed the presence of putative tumor cells that were positive for epithelial cell adhesion molecule (EpCAM and cytokeratin (CK expression. This study confirmed the hematogenous dissemination of esophageal cancer by the detection of circulating tumor cells in the peripheral blood, and is the first to demonstrate that tumor cells can be identified in ascitic fluid by using CellSearch® technology.

    The diagnosis of tuberculosis (TB) ascites using standard diagnostic tools is difficult. The aim of the present meta-analysis was to establish the overall diagnostic accuracy of adenosine deaminase (ADA) levels in ascites for diagnosing TB ascites. A systematic review was performed of English language publications prior to April 2013. Sensitivity, specificity, and other measures of the accuracy of ADA for the diagnosis of TB ascites using ascites fluid were summarized using a random-effects model or a fixed-effects model. Receiver operating characteristic curves were used to summarize overall test performance. Seventeen studies involving 1797 subjects were eligible for the analysis. The summary estimates of sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and the area under cure of overall analysis were: 0.93, 0.94, 13.55, 0.11, 169.83, and 0.976, respectively; the results of sensitivity analysis of studies that used Giusti method were 0.94, 0.94, 12.99, 0.08, 183.18, and 0.977, respectively. Our results suggest that ADA in the ascites can be a sensitive and specific target and a critical criterion for the diagnosis of TB ascites. Copyright © 2014 Elsevier Inc. All rights reserved.

    The proteome analysis of bile fluid represents a promising strategy to identify biomarker candidates for various diseases of the hepatobiliary system. However, to obtain substantive results in biomarker discovery studies large patient cohorts necessarily need to be analyzed. Consequently, this would lead to an unmanageable number of samples to be analyzed if sample preparation protocols with extensive fractionation methods are applied. Hence, the performance of simple workflows allowing for "one sample, one shot" experiments have been evaluated in this study. In detail, sixteen different protocols implying modifications at the stages of desalting, delipidation, deglycosylation and tryptic digestion have been examined. Each method has been individually evaluated regarding various performance criteria and comparative analyses have been conducted to uncover possible complementarities. Here, the best performance in terms of proteome coverage has been assessed for a combination of acetone precipitation with in-gel digestion. Finally, a mapping of all obtained protein identifications with putative biomarkers for hepatocellular carcinoma (HCC) and cholangiocellular carcinoma (CCC) revealed several proteins easily detectable in bile fluid. These results can build the basis for future studies with large and well-defined patient cohorts in a more disease-related context. Human bile fluid is a proximal body fluid and supposed to be a potential source of disease markers. However, due to its biochemical composition, the proteome analysis of bile fluid still represents a challenging task and is therefore mostly conducted using extensive fractionation procedures. This in turn leads to a high number of mass spectrometric measurements for one biological sample. Considering the fact that in order to overcome the biological variability a high number of biological samples needs to be analyzed in biomarker discovery studies, this leads to the dilemma of an unmanageable number of

    The formation of bile depends on the structural and functional integrity of the bile-secretory apparatus and its impairment, in different situations, results in the syndrome of cholestasis. The structural bases that permit bile secretion as well as various aspects related with its composition and flow rate in physiological conditions will first be reviewed. Canalicular bile is produced by polarized hepatocytes that hold transporters in their basolateral (sinusoidal) and apical (canalicular) plasma membrane. This review summarizes recent data on the molecular determinants of this primary bile formation. The major function of the biliary tree is modification of canalicular bile by secretory and reabsorptive processes in bile-duct epithelial cells (cholangiocytes) as bile passes through bile ducts. The mechanisms of fluid and solute transport in cholangiocytes will also be discussed. In contrast to hepatocytes where secretion is constant and poorly controlled, cholangiocyte secretion is regulated by hormones and nerves. A short section dedicated to these regulatory mechanisms of bile secretion has been included. The aim of this revision was to set the bases for other reviews in this series that will be devoted to specific issues related with biliary physiology and pathology.

    Full Text Available Chylous ascites is rare in clinical practice. It is characterized by milky-appearing peritoneal fluid with a triglycerides concentration of >1.25 mmol/l (110 mg/dl. Its pathophysiology is related to a disruption in the normal lymphatic flow. It is more common after trauma (including post surgery, neoplasia or atypical infections such as tuberculosis or filariasis. Other rare medical causes have been reported. The treatment is supportive and focused on correction of the underlying pathology. We report here the first case of chylous ascites caused by giant liver hemangioma and discuss the management of this condition.

The history of the patient originating from former Jugoslavia was suspicious for inadequately treated tuberculous pericarditis. Hence this diagnosis tuberculous peritonitis became probable but for practical reasons could not be proven neither by biopsy nor by culture. Under probatory antituberculous treatment the patient's general condition improved rapidly, the ascites disappeared and initially elevated parameters for infection normalized.

    The aim of this investigation was to develop a procedure to improve the dissolution and bioavailability of silymarin (SM) by using bile salt-containing liposomes that were prepared by supercritical fluid technology (ie, solution-enhanced dispersion by supercritical fluids [SEDS]). The process for the preparation of SM-loaded liposomes containing a bile salt (SM-Lip-SEDS) was optimized using a central composite design of response surface methodology with the ratio of SM to phospholipids (w/w), flow rate of solution (mL/min), and pressure (MPa) as independent variables. Particle size, entrapment efficiency (EE), and drug loading (DL) were dependent variables for optimization of the process and formulation variables. The particle size, zeta potential, EE, and DL of the optimized SM-Lip-SEDS were 160.5 nm, −62.3 mV, 91.4%, and 4.73%, respectively. Two other methods to produce SM liposomes were compared to the SEDS method. The liposomes obtained by the SEDS method exhibited the highest EE and DL, smallest particle size, and best stability compared to liposomes produced by the thin-film dispersion and reversed-phase evaporation methods. Compared to the SM powder, SM-Lip-SEDS showed increased in vitro drug release. The in vivo AUC0−t of SM-Lip-SEDS was 4.8-fold higher than that of the SM powder. These results illustrate that liposomes containing a bile salt can be used to enhance the oral bioavailability of SM and that supercritical fluid technology is suitable for the preparation of liposomes.

    The overexpression of soluble human leukocyte antigen-G is associated with malignant tumours. The purpose of our study was to detect soluble human leukocyte antigen-G concentrations in ascites and to evaluate the value of ascitic soluble human leukocyte antigen-G for the diagnosis of malignant ascites. Enzyme-linked immunosorbent assay was used to detect soluble human leukocyte antigen-G levels in 64 patients with malignant ascites and 30 patients with benign ascites. Receiver operating characteristic curves were used to evaluate the diagnostic efficacy of ascitic soluble human leukocyte antigen-G for the detection of malignant ascites. Ascitic soluble human leukocyte antigen-G levels were significantly higher in the malignant ascites group than in the benign ascites group (20.718 ± 3.215 versus 12.467 ± 3.678 µg/L, t = 7.425, p human leukocyte antigen-G was 0.957 (95% confidence interval, 0.872-0.992). At a cut-off value of 19.60 µg/L, the sensitivity and specificity of ascitic soluble human leukocyte antigen-G were 87.5% (95% confidence interval, 71.0%-96.5%) and 100% (95% confidence interval, 88.4%-100%), respectively. With respect to area under the receiver operating characteristic curve, sensitivity and specificity, ascitic carcinoembryonic antigen (0.810, 68.75% and 83.33%, respectively) and carbohydrate antigen 19-9 (0.710, 65.63% and 70%, respectively) significantly differed (all p human leukocyte antigen-G was 75%, which was higher than the corresponding rates for ascitic carcinoembryonic antigen (31.25%) and carbohydrate antigen 19-9 (6.25%; both p human leukocyte antigen-G exhibited good performance for diagnosing malignant ascites, and particularly those that were cytology-negative and biopsy-positive.

    The diagnosis of malignant ascites is a challenging problem in clinical practice, non-invasive techniques should be developed to improve diagnostic accuracy. The diagnostic performances of tumor markers in malignant ascites remained unsettled. Our aim was to evaluate diagnostic performance of tumor markers in differential diagnosis of benign and malignant ascites. A total of 437 patients were enrolled, and the relevant parameters of the patients were analyzed for the differentiation of benign ascites from malignant ascites. At the predetermined cutoff values of tumor makers, tumor markers in ascitic fluid showed better diagnostic performance than those in serum. Combined use of tumor markers and the cytology increased the diagnostic yield of the latter by 37%. In cytologically negative malignant ascites, tumor markers provided assistance in differentiating malignant ascites from benign ascites, and the combination of ascitic tumor markers yielded 86% sensitivity, 97% specificity. Use of a panel of tumor markers exhibited excellent diagnostic performance in diagnosing malignant ascites, which indicated the detection of tumor markers may represent a beneficial adjunct to cytology, thus guiding the selection of patients who might benefit from further invasive procedures.

    Full Text Available OBJECTIVES: To present the clinical features and outcomes of outpatients who suffer from refractory ascites. METHODS: This prospective observational study consecutively enrolled patients with cirrhotic ascites who submitted to a clinical evaluation, a sodium restriction diet, biochemical blood tests, 24 hour urine tests and an ascitic fluid analysis. All patients received a multidisciplinary evaluation and diuretic treatment. Patients who did not respond to the diuretic treatment were controlled by therapeutic serial paracentesis, and a transjugular intrahepatic portosystemic shunt was indicated for patients who required therapeutic serial paracentesis up to twice a month. RESULTS: The most common etiology of cirrhosis in both groups was alcoholism [49 refractory (R and 11 non-refractory ascites (NR]. The majority of patients in the refractory group had Child-Pugh class B cirrhosis (p=0.034. The nutritional assessment showed protein-energy malnutrition in 81.6% of the patients in the R group and 35.5% of the patients in the NR group, while hepatic encephalopathy, hernia, spontaneous bacterial peritonitis, upper digestive hemorrhage and type 2 hepatorenal syndrome were present in 51%, 44.9%, 38.8%, 38.8% and 26.5% of the patients in the R group and 9.1%, 18.2%, 0%, 0% and 0% of the patients in the NR group, respectively (p=0.016, p=0.173, p=0.012, p=0.012, and p=0.100, respectively. Mortality occurred in 28.6% of the patients in the R group and in 9.1% of the patients in the NR group (p=0.262. CONCLUSION: Patients with refractory ascites were malnourished, suffered from hernias, had a high prevalence of complications and had a high postoperative death frequency, which was mostly due to infectious processes.

    Chylous ascites derives from chyle leakage into the peritoneal cavity, either due to rupture or obstruction of abdominal lymphatic vessels. The main clinical sign is abdominal distention, while diagnosis requires the presence of triglycerides in ascitic fluid. Neoplasms are the most common cause of chylous ascites, although less common causes, such as abdominal surgery, should also be considered. The mainstay of therapy is hyperproteic diet with fat restriction and middle-chain triglycerides. Parenteral nutrition is reserved for cases in which dietary treatment fails to restore an optimal nutritional status or is contraindicated, whereas surgery is considered for patients that are deemed refractory to conservative therapy. We present a case of chylous ascites secondary to retroperitoneal lymphadenectomy.

    Mice were injected daily with a radioprotector WR-2721 (S-2-[3-aminopropyl-amino]ethylphosphorothioic acid) after inoculation with Ehrlich's ascites tumor cells. Increases in weight of mice, volume of ascitic fluid and number of ascitic cells per mouse were reduced by the daily administration of 5 mg/mouse of the drug, indicating a suppressive effect of WR-2721 on growth of ascitic cells. But daily treatment with 5 mg/mouse of WR-2721 caused earlier death of tumor-bearing mice. (author)

    Full Text Available Ascites is a pathologic accumulation of fluid within the peritoneal cavity, and usually develops as a result of liver disease, congestive heart failure or nephrotic syndrome. Ascites is also a common manifestation of some gynecologic diseases. It is important that health care workers consider gynecologic problems among the potential differential diagnoses in patients presenting with ascites. Various kinds of ovarian diseases, such as epithelial ovarian cancer, benign ovarian fibroma, stromal hyperplasia, ovarian hyperstimulation syndrome, primary peritoneal serous carcinoma, endometriosis and peritoneal tuberculosis, should be kept in mind when women are found to have ascites.

    Simultaneous presence of ascites and pleural effusion has been documented in patients with cirrhosis of the liver, renal disease, Meigs' syndrome and in patients undergoing peritoneal dialysis. Mechanisms proposed in the formation of pleural effusion in most of the above diseases are lymphatic drainage and diaphragmatic defect. But sometimes, hepatic hydrothoraxes in the absence of clinical ascites and pleural effusion secondary to pulmonary or cardiac disease are noted. It is not always possible to differentiate between pleural effusion caused by transdiaphragmatic migration of ascites and by other causes based solely on biochemical analysis. Authors performed radionuclide scintigraphy after intraperitoneal administration of 99m Tc-labeled colloid in 23 patients with both ascites and pleural effusion in order to discriminate causative mechanisms responsible for pleural effusion. Scintigraphy demonstrated the transdiaphtagmatic flow of fluid from the peritoneum to pleural cavities in 13 patients correctly. In contrast, in 5 patients with pleural effusion secondary to pulmonary, pleural and cardiac diseases, radiotracers fail to traverse the diaphragm and localize in the pleural space. Ascites draining to mediastinal lymph nodes and blocked passage of lymphatic drainage were also clarified, additionally. Conclusively, radionuclide peritoneal scintigraphy is an accurate, rapid and easy diagnostic tool in patients with both ascites and pleural effusion. It enables the causes of pleural effusion to be elucidated, as well as providing valuable information required when determining the appropriate therapy.

    The availability of new biliary radiopharamaceutical led to the expectation that the physiology and the pathophysiology of bile would be resolved. Some aspects of the physiology of bile have clarified and it has been shown that nasogastric intubation does not cause bile reflux. Careful analysis of excretion patterns has allowed detection of obstruction of the bile duct after cholecystectomy, and the radiopharmaceuticals have proved helpful in the diagnosis of acute colecystitis. In chronic cholecystitis, however, varying results have been obtained. Information on the incidence and amount of reflux in normal subjects is also confused, since several different techniques have been used with widely varying results. The clinical value of biliary dynamic studies is at present limited in patients with chronic cholecystitis, peptic ulcer, or symptoms suggestive of bile reflux. More data, with appropriate control subjects, is required to identify abnormal reflux, determine its effects, and decide on appropriate treatment

    The role of contaminated preservation fluid in the development of infection after liver transplantation has not been fully elucidated. To assess the incidence and etiology of contaminated preservation fluid and determine its impact on the subsequent development of infection after liver transplantation, we prospectively studied 50 consecutive liver transplants, and cultured the following samples in each instance: preservation fluid (immediately before and at the end of the back-table procedure, and just before implantation), blood, and bile from the donor, and ascitic fluid from the recipient. When any culture was positive, blood cultures were obtained and targeted antimicrobial therapy was started. We found that the incidence of contaminated preservation fluid was 92% (46 of 50 cases of liver transplantation per year), but only 28% (14/50) were contaminated by recognized pathogens. Blood and bile cultures from the donor were positive in 28% and 6% respectively, whereas ascitic fluid was positive in 22%. The most frequently isolated microorganisms were coagulase-negative staphylococci. In nine cases, the microorganisms isolated from the preservation fluid concurred with those grown from the donor blood cultures, and in one case, the isolate matched with the one obtained from bile culture. No liver transplant recipient developed an infection due to the transmission of an organism isolated from the preservation fluid. Our findings indicate that contamination of the preservation fluid is frequent in liver transplantation, and it is mainly caused by saprophytic skin flora. Transmission of infection is low, particularly among those recipients given targeted antimicrobial treatment for organisms isolated in the preservation fluid.

    To investigate the feasibility of magnetization transfer contrast (MTC) in characterization of pelvic cystic masses and ascites, in vitro studies were performed. Cystic fluids were taken from operative specimens of ten ovarian cystic masses (five mucinous cystadenomas, one cystadenocarcinoma, two serous cystadenocarcinomas, two clear cell carcinomas) and three non-ovarian pelvic cysts (one paraovarian cyst, one pseudomyxoma peritonei, one pelvic abscess). Samples of ascitic flied were drawn by peritoneal puncture in twenty patients (thirteen with peritonitis carcinomatosa, five with liver dysfunction, two with renal dysfunction). Total protein content in ascitic fluids was measured. Magnetization transfer ratio (MTR) was calculated by the signal intensities under the gradient echo sequence with and without the application of off-resonance pulses. The relative signal intensities (RSI) relative to water in T{sub 1} and T{sub 2} weighted images were obtained using spin echo sequence. There was no correlation between histological type of pelvic mass and MTR and RSI. Good correlation (R{sup 2}=0.761) was obtained between MTR and protein content in ascitic fluids, whereas no correlation was noted between RSI and protein content in ascitic fluids. These results suggest that MTC is not useful in the characterization of pelvic masses but is applicable in the differentiation between exudative ascites and transudative ascites. (author)

    Full Text Available Lila Ammouri, Eric E PrommerMayo Clinic Hospice and Palliative Medicine Program, Mayo Clinic College of Medicine, Mayo Clinic Hospital, Scottsdale, AZ, USAAbstract: Malignant ascites is the abnormal accumulation of fluid in the peritoneal cavity associated with several intrapelvic and intra-abdominal malignancies. The development of ascites leads to significant symptoms and poor quality of life for the cancer patient. Available therapies for palliation include treatment of the underlying disease, but when there are no treatment options, the use of diuretics, implantation of drainage catheters, and surgical shunting techniques are considered. None of these symptom palliation options affect the course of disease. The development of trifunctional antibodies, which attach to specific overexpressed surface markers on tumor cells, and trigger an immune response leading to cytoreductive effects, represents a new approach to the management of malignant ascites. The purpose of this review is to highlight current therapies for malignant ascites and review data as to the effectiveness of a new trifunctional antibody, catumaxomab.Keywords: catumaxomab, ascites, trifunctional

  11. Infectious peritonitis after endoscopic ultrasound-guided biliary drainage in a patient with ascites

    Full Text Available Summary of Event: Bacterial, mycotic peritonitis and Candida fungemia developed in a patient with moderate ascites who had undergone endoscopic ultrasound-guided biliary drainage (EUS-BD. Antibiotics and antifungal agent were administered and ascites drainage was performed. Although the infection improved, the patient’s general condition gradually deteriorated due to aggravation of the primary cancer and he died.Teaching Point: This is the first report to describe infectious peritonitis after EUS-BD. Ascites carries the potential risk of severe complications. As such, in patients with ascites, endoscopic retrograde cholangiopancreatography (ERCP is typically preferred over EUS-BD or percutaneous drainage to prevent bile leakage. However, ERCP may not be possible in some patients with tumor invasion of the duodenum or with surgically altered anatomy. Thus, in patients with ascites who require EUS-BD, we recommend inserting the drainage tube percutaneously and draining the ascites before and after the intervention in order to prevent severe infection.

    Gastroesophageal reflux disease (GERD) is thought to lead to aspiration and bronchiolitis obliterans syndrome after lung transplantation. Unfortunately, the identification of patients with GERD who aspirate still lacks clear diagnostic indicators. The authors hypothesized that symptoms of GERD and detection of pepsin and bile acids in the bronchoalveolar lavage fluid (BAL) and exhaled breath condensate (EBC) are effective for identifying lung transplantation patients with GERD-induced aspiration. From November 2009 to November 2010, 85 lung transplantation patients undergoing surveillance bronchoscopy were prospectively enrolled. For these patients, self-reported symptoms of GERD were correlated with levels of pepsin and bile acids in BAL and EBC and with GERD status assessed by 24-h pH monitoring. The sensitivity and specificity of pepsin and bile acids in BAL and EBC also were compared with the presence of GERD in 24-h pH monitoring. The typical symptoms of GERD (heartburn and regurgitation) had modest sensitivity and specificity for detecting GERD and aspiration. The atypical symptoms of GERD (aspiration and bronchitis) showed better identification of aspiration as measured by detection of pepsin and bile acids in BAL. The sensitivity and specificity of pepsin in BAL compared with GERD by 24-h pH monitoring were respectively 60 and 45 %, whereas the sensitivity and specificity of bile acids in BAL were 67 and 80 %. These data indicate that the measurement of pepsin and bile acids in BAL can provide additional data for identifying lung transplantation patients at risk for GERD-induced aspiration compared with symptoms or 24-h pH monitoring alone. These results support a diagnostic role for detecting markers of aspiration in BAL, but this must be validated in larger studies.

    Background. Small volumes of fluid in the pleural and peritoneal cavities are common after paediatric liver transplantation. Occasionally, larger fluid collections develop and need intervention by aspiration or insertion of a drain. Objective. To assess the incidence of moderate and large pleural and peritoneal fluid collections following paediatric liver transplantation, the need for intervention and the outcome following radiological and non-radiological treatment, with the ultimate objective of recommending a treatment protocol for such post-operative fluid collections. Materials and methods. A total of 184 consecutive liver grafts in 164 children were reviewed. Results. Of 184 grafts, 31 (16.8 %) developed excessive fluid collections requiring intervention (19 pleural effusions, 8 ascites and 4 effusions and ascites). The effusions were first diagnosed between days 1 and 44 after transplant and the ascites between days 1 and 14. The initial diagnosis was made radiologically in 21 (91 %) of 23 pleural effusions and in 10 (83 %) of 12 ascites. No identifiable cause or association was seen in 18 (58 %) of 31 cases. The mean duration of the pleural effusions and ascites, from onset of treatment to resolution, ranged from 33 {+-} 42 days (SD) to 35 {+-} 48 days and from 36 {+-} 47 days to 39 {+-} 46 days respectively. Comparison of the modes of interventional treatment (i. e. unguided, radiological and surgical) showed no statistically significant difference in the outcome of the management. Conclusions. Post-transplantation pleural effusions and ascites requiring intervention are often without definite cause. They are more common with reduced grafts, but this cannot completely explain the occurrence or the protracted duration of accumulation in spite of combined interventional management. The outcome of treatment is not significantly influenced by the mode of intervention except in cases where surgical intervention is indicated. Patients could be managed

    2008-11-01

    Full Text Available A 65-year-old man with chronic hepatitis C and no history of alcohol abuse was admitted to our liver unit for the recent development of massive ascites and presumed hepatorenal syndrome. In the preceding two weeks, he had received medical treatment for acute pancreatitis and cholecystitis. Abdominal paracentesis demonstrated a cloudy, orange peritoneal fluid, with total protein concentration 3.6 g/dl, serum-ascites albumin gradient 1.0 g/dl, and ratios of ascites-serum bilirubin and amylase approximately 8:1. Diagnostic imaging demonstrated no pancreatic pseudocysts. Ten days later, at laparotomy, acalculous perforation of the gallbladder was identified. After cholecystectomy, amylase concentration in the ascitic fluid dropped within a few days to 40% of serum values; ascites disappeared within a few weeks. We conclude that in the presence of a perforated gallbladder, pancreatobiliary reflux was responsible for this unusual combination of choleperitoneum and pancreatic ascites, which we propose to call pancreatobiliary ascites.

    Bile duct injury after ablation of malignant liver tumors (MLTs) was not unusual and should be avoided. However, few studies have focused on evaluating the risk factors for intrahepatic bile duct injury. To evaluate the risk factors for intrahepatic bile duct injury after ablation of MLTs and to evaluate the minimum safe distance for ablating tumors abutting bile ducts. Sixty-five patients with intrahepatic bile duct injury after ablation of MLTs, and 65 controls were recruited. Risk factors for intrahepatic bile duct injury were analyzed. Tumor location was recorded as ≤5 mm (group A), 5-10 mm (group B), and >10 mm (group C) from the right/left main duct or segmental bile duct.

    Full Text Available Abstract Background The production of ascites is a common complication of ovarian cancer. Ascites constitute a unique tumor microenvironment that may affect disease progression. In this context, we recently showed that ovarian cancer ascites may protect tumor cells from TRAIL-induced apoptosis. In this study, we sought to determine whether the prosurvival effect of ascites affects disease-free intervals. Methods Peritoneal fluids were obtained from 54 women undergoing intra-abdominal surgery for suspected ovarian cancer (44 cancers and 10 benign diseases. The ability of peritoneal fluids to protect from TRAIL was assessed in the ovarian cancer cell line CaOV3, and IC50 were determined. The anti-apoptotic activity of 6 ascites against cisplatin, paclitaxel, doxorubicin, etoposide and vinorelbine was also assessed in CaOV3 cells, and the prosurvival activity of two ascites was assessed in 9 primary ovarian cancer cultures. Results Among the 54 peritoneal fluids tested, inhibition of TRAIL cytotoxicity was variable. Fluids originating from ovarian cancer were generally more protective than fluids from non-malignant diseases. Most of the 44 ovarian cancer ascites increased TRAIL IC50 and this inhibitory effect did not correlate strongly with the protein concentration in these ascites or the levels of serum CA125, a tumor antigen which is used in the clinic as a marker of tumor burden. The effect of ascites on cisplatin- and paclitaxel-induced cell death was assessed with 4 ascites having inhibitory effect on TRAIL-induced cell death and 2 that do not. The four ascites with prosurvival activity against TRAIL had some inhibitory on cisplatin and/or paclitaxel. Two ovarian cancer ascites, OVC346 and OVC509, also inhibited TRAIL cytotoxicity in 9 primary cultures of ovarian tumor and induced Akt activation in three of these primary cultures. Among a cohort of 35 patients with ascites, a threshold of TRAIL IC50 with ascites/IC50 without ascites > 2 was

    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.

    Full Text Available Eosinophilic gastroenteritis is a rare gastrointestinal (GI disorder characterized by nonspecific GI symptoms, peripheral eosinophilia, and eosinophilic infiltration of the intestinal wall. The disorder is classified into mucosal, muscular, and sub-serosal types, depending on the clinical picture and the depth of eosinophilic infiltration within the GI wall. Sub-serosal disease, which is complicated by ascites, usually results in the most severe clinical form of eosinophilic gastroenteritis and requires early corticosteroid therapy. In such cases, a favorable outcome can be achieved after a short course of corticosteroids. We present the case of a 28-year-old female with diffuse abdominal pain and distention for 2 weeks. Her physical examination was significant for moderate ascites. Initial work-up demonstrated severe peripheral blood eosinophilia, normal liver function tests, and elevated serum immunoglobulin E (IgE. Upper endoscopy, colonoscopy showed a thickening of the stomach and colon, and biopsies showed marked eosinophilic infiltration of the mucosa. Ascitic fluid analysis showed significant eosinophilia. Subsequent treatment with oral prednisone resulted in the normalization of laboratory and radiologic abnormalities 45 days after the start of the treatment. Despite its rarity, eosinophilic gastroenteritis needs to be recognized by the clinician because the disease is treatable, and timely diagnosis and initiation of treatment could be of major importance.

    Poly(A)-containing RNA (m-RNA) was studied in in vivo growing Ehrlich ascites tumour cells following a roentgen irradiation dose of 5 Gy. m-RNA increased significantly during the first 12 hours after irradiation. Thus, the observed decrease in protein synthesis rate during this time seems not to be due to radiation induced changes at the transcriptional level. The protein synthesis rate of in vivo irradiated cells incubated in vitro in culture medium was unchanged. On the other hand, the protein synthesis rate of non-irradiated cells incubated in vitro in ascites fluid from irradiated animals was decreased. We concluded that factor(s) inhibiting protein synthesis or the lack of factor(s) promoting protein synthesis in the ascites fluid is(are) of significance for the reduced protein synthesis of tumour cells found in irradiated in vivo growing cells.

    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.

    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.

    Full Text Available Transmesenteric hernia is an internal hernia without sac, which forms through a congenital mesentery defect. Mostly diagnosed intraoperatively, it as a variable prognosis, which can lead to high morbidity and mortality.The authors describe a case of transmesenteric hernia that presented as isolated fetal ascites. A 34 week preterm baby was delivered by forceps, with respiratory compromise due to abdominal distension. Orotracheal intubation and evacuation paracentesis were performed. After excluding major causes of neonatal ascites and persistent bowel loop distension, the newborn underwent an exploratory laparotomy, where a transmesenteric hernia and pellets of meconium were identified. Hernia reduction, enterectomy and enterostomies were performed, with good outcome. Cystic fibrosis was diagnosed during post-operatory period.This is the first reported case of transmesenteric hernia presenting as fetal ascites, without associated morbidity or mortality due to an early intervention.

    Malignant ascites is common in various types of cancers and is difficult to manage. Vascular endothelial growth factor (VEGF) has a pivotal role in malignant ascites. The matrix protein of vesicular stomatitis virus (VSVMP) has been shown to inhibit host gene expression and induce the apoptosis of cancer cells. The present study was designed to determine whether VSVMP suppresses the formation of ascites in ascites-producing peritoneal carcinomatosis. BALB/c female mice, 6-8 weeks old, bearing peritoneal tumors of H22 or MethA cells received an intraperitoneal administration of 50 μg VSVMP/250 μg liposome complexes, 50 μg empty plasmid/250 μg liposome complexes or 0.9% NaCl solution, respectively, every 2 days for 3 weeks. Administration of VSVMP resulted in a significant inhibition in ascites formation, improvement in health condition and prolonged survival of the treated mice. Decreased peritoneum osmolarity and reduced tumor vascularity coincided with dramatic reductions in the VEGF level in ascites fluid and plasma. Examination of floating tumor cells collected from the peritoneal wash revealed an apparently increased number of apoptotic cells and profound downregulation of VEGF mRNA in the VSVMP-treated mice. Our data indicate for the first time that in BALB/c mice bearing H22 or MethA cell peritoneal tumors, VSVMP may inhibit VEGF production and suppress angiogenesis, consequently abolishing ascites formation.

    Ascites accumulation is the product of a complex process involving hepatic, renal, systemic, hemodynamic, and neurohormonal factors. The main pathophysiologic theories of ascites formation include the "underfill," "overflow," and peripheral arterial vasodilation hypotheses. These theories are not necessarily mutually exclusive and are linked at some level by a common pathophysiologic thread: The body senses a decreased effective arterial blood volume, leading to stimulation of the sympathetic nervous system, arginine-vasopressin feedback loops, and the renin-angiotensin-aldosterone system. Cornerstones of ascites management include dietary sodium restriction and diuretics. Spironolactone is generally tried initially, with furosemide added if clinical response is suboptimal. More refractory patients require large-volume paracentesis (LVP) accompanied by volume expansion with albumin. Placement of a transjugular intrahepatic portosystemic shunt is reserved for individuals with compensated liver function who require very frequent sessions of LVP. Peritoneovenous shunts are not used in contemporary ascites management. Liver transplantation remains the definitive therapy for refractory ascites. Although treatment of ascites fails to improve survival, it benefits quality of life and limits the development of such complications as spontaneous bacterial peritonitis.

    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.

    2014-01-01

    Bile acids are synthesized in the liver from cholesterol and have traditionally been recognized for their role in absorption of lipids and in cholesterol homeostasis. In recent years, however, bile acids have emerged as metabolic signaling molecules that are involved in the regulation of lipid...... and glucose metabolism, and possibly energy homeostasis, through activation of the bile acid receptors farnesoid X receptor (FXR) and TGR5. Bile acid sequestrants (BASs) constitute a class of drugs that bind bile acids in the intestine to form a nonabsorbable complex resulting in interruption...... of the enterohepatic circulation. This increases bile acid synthesis and consequently reduces serum low-density lipoprotein cholesterol. Also, BASs improve glycemic control in patients with type 2 diabetes. Despite a growing understanding of the impact of BASs on glucose metabolism, the mechanisms behind their glucose...

    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.

  17. Optimization of monoclonal antibody production in mouse ascites by single whole-body irradiation

    1987-01-01

    Hybridoma cells injected intraperitoneally into mice induce formation of ascites tumors producing ascites fluid with high levels of monoclonal antibodies. Several parameters affect the growth of the immunoglobulin-producing tumors in vivo. In 10 different hybridomas the average ascites tumor formation rate could be increased from 32% (n = 338 mice) to 77% (n = 112 mice) by only one whole-body irradiation of paraffin-pretreated Balb/c mice. Production of monoclonal antibodies was better in males because of the significantly (p < 0.01) increased volume of ascites fluid. From the increased tumor formation rate in irradiated mice it is suggested that in non-irradiated recipients the tumor growth rate was lowered by immunological reactions against hybridoma cells provoked by cell surface neoantigens revealed by cell fusion and/or tumor-associated antigens of the myeloma parent cells as well as by altered antigen pattern caused by possible mutations in the myeloma cell line and/or Balb/c/K strain.

  20. Strategies to alleviate the incidence of ascites in broilers: a review

    2005-12-01

    Full Text Available Ascites is a complex problem caused by many interacting factors such as genetics, environment and management. Many nutritional, medicinal and management strategies have been proposed to alleviate the problem. Higher levels of dietary vitamin C and E along with selenium yeast might be beneficial, presumably because of their role in improving cellular integrity. Oils rich in n-3 fatty acids have been shown to reduce pulmonary hypertension and, consequently, ascites incidence. The potential use of flax oil has already been demonstrated, whereas the effects of other oils rich in n-3 fatty acids (fish, linseed and canola oils remain to be investigated. The assessment of the effects of dietary electrolyte balance on ascites incidence seems to be a promising field of research in broiler nutrition. In general, reducing the dietary level of salt (NaCl and adding bicarbonates to the diet and drinking water have been proposed as potential "cost-effective" methods to reduce ascites incidence. The use of nutrients/drug agents that increase the vascular capacity of the lungs or decrease the pulmonary vascular resistance may help to alleviate the problem, but economic and local feed regulations might restrict such use. Diuretics have also shown positive effects, presumably because there is a reduction of sodium and fluid retention in the body; litter humidity however must be closely monitored if diuretics are continuously administered. As the high metabolic rate (fast growth is a major factor contributing to the susceptibility of broilers to ascites, early-age feed or nutrient restriction (qualitative or quantitative or light restriction in order to slow down the growth rate seem practically viable methods, since final body weight is not compromised. Optimization of the house temperature and ventilation in cold weather seem helpful practices to decrease ascites incidence. Under practical conditions, it might be interesting to test the additive effects of

    Full Text Available BackgroundEpithelial ovarian cancer (EOC remains a highly lethal gynecological malignancy. Ascites, an accumulation of peritoneal fluid present in one-third of patients at presentation, is linked to poor prognosis. High levels of regulatory T cells (Tregs in ascites are correlated with tumor progression and reduced survival. Malignant ascites harbors high levels of Tregs expressing the tumor necrosis factor receptor 2 (TNFR2, as well as pro-inflammatory factors such as interleukin 6 (IL-6 and tumor necrosis factor (TNF. IL-6 is also associated with poor prognosis. Herein, we study the effect of IL-6 and TNF present in ascites on the modulation of TNFR2 expression on T cells, and specifically Tregs.MethodsAscites and respective peripheral blood sera were collected from 18 patients with advanced EOC and soluble biomarkers, including IL-6, sTNFR2, IL-10, TGF-β, and TNF, were quantified using multiplexed bead-based immunoassay. Peripheral blood mononuclear cells (PBMC from healthy donors were incubated with cell-free ascites for 48 h (or media as a negative control. In some experiments, IL-6 or TNF within the ascites were neutralized by using monoclonal antibodies. The phenotype of TNFR2+ Tregs and TNFR2− Tregs were characterized post incubation in ascites. In some experiments, cell sorted Tregs were utilized instead of PBMC.ResultsHigh levels of immunosuppressive (sTNFR2, IL-10, and TGF-β and pro-inflammatory cytokines (IL-6 and TNF were present in malignant ascites. TNFR2 expression on all T cell subsets was higher in post culture in ascites and highest on CD4+CD25hiFoxP3+ Tregs, resulting in an increased TNFR2+ Treg/effector T cell ratio. Furthermore, TNFR2+ Tregs conditioned in ascites expressed higher levels of the functional immunosuppressive molecules programmed cell death ligand-1, CTLA-4, and GARP. Functionally, TNFR2+ Treg frequency was inversely correlated with interferon-gamma (IFN-γ production by effector T cells, and was

    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.

    Full Text Available Studying the effects of different bile acids in the body in recent years significantly increased the understanding of their physiological functions. The role of bile acids is to transfer to Striated border of enterocytes lipids in high micellar concentration and subsequent return them to the water layer in the molecular form. The rate of diffusion of molecules or particles is inversely proportional to the square root of the magnitude of their molecular weight. Main components of the glycoprotein complex (GPC allows to preserve the natural structure of mucosa. Previous physicochemical experiments on GPC established presence of bile acids (3,5 to 10 mg/ml, enzymes (amylase and lipase, amino acids (from 10150 to 29500 ug/ml in the complex. Objective. The aim was to study the influence of bile on fat filtration on the model of GPC. Method and Materials. Soaked filters were put on the tubes: with bile - the first, water - the second group, GPC bile at a dose of 25 mg/kg - the third group. Then on each filter was poured 2 ml of liquid fat. 30 minutes after the start of the experiment the amount of liquid fat that passes through the filter was measured. Results and Discussion. As established in the first group (bile medical, the amount of liquid fat, which passed through the filter amounted to 1,85±0,02 ml. In the second group (water - 0,30 ± 0,03 ml. In the third group (GPC 25 mg/kg - 1,75±0,02 ml. After that the impact of GPC bile in emulsification of fats was studied. 1 ml of vegetable oil and 1,5 ml of purified water were contributed in three series of tubes. The first series of test tubes left unchanged. In the other two 2 ml in 2 series - medical bile in 3 series - GPC bile were added. Tubes were shaken in all series. In the first (control series observed the formation of turbid fluid - emulsion. However, in a few seconds instability of the emulsion was detected. In the second and third series of tubes formation of stable emulsions which are

    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.

    The effects of bile duct ligation (BDL), choledochostomy, bile acid sequestering within the intestinal lumen by cholestyramine, and fluid and electrolyte replacement on survival time and development of diarrhea after whole-body exposure to doses of ionizing radiation that result in death from acute intestinal injury were studied. BDL significantly prolonged survival and delayed the onset of diarrhea after exposure to 137 Cs gamma rays, fission neutrons, or cyclotron-produced neutrons in the range of doses that produce intestinal death or death from a combination of intestinal and hematopoietic injuries. Cannulation of the bile duct with exteriorized bile flow (choledochostomy) to protect the irradiated intestine from the mucolytic action of bile salts did not duplicate the effect of BDL in increasing survival time. Choledochostomy without fluid replacement eliminated the occurrence of diarrhea in 15.4 Gy irradiated rats. Diarrhea did occur in irradiated animals with choledochostomy if they received duodenal injections of fluid and electrolytes to replace the fluid lost as a result of bile drainage. Duodenal injection of fluid and electrolytes had no significant effect on survival time in irradiated rats. Injection of fluid and electrolytes into the peritoneal cavity of irradiated rats resulted in an increase in survival time that was comparable to that observed after BDL. Addition of antibiotics to the peritoneally injected fluid and electrolytes further increased survival time (up to 9 days). This survival time approached that seen in animals receiving the same radiation dose but which had the intestine exteriorized and shielded to minimize radiation injury to the intestine. Postmortem histological examinations of the irradiated small intestine showed mucosal regeneration in these long-term survivors receiving fluid and antibiotic therapy

    Full Text Available 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.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.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.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.

    Full Text Available Chyloperitoneum is the accumulation of lymphatic fluid in the peritoneal cavity. Chylous ascites can occur if it is not recognized during surgery. The incidence of chylous ascites after oncological surgery was approximately 7.4% however, the incidence of lymphorrhea after radical gastrectomy for gastric cancer is so low. Extensive lymph node dissection leads to a higher incidence of lymphorrhea. There have been few cases associated with D1 dissection In most patients conservative treatment is recommended that includes paracentesis, total parenteral nutrition (TPN, a medium chain triglyceride (MCT based diet, and somatostatin. Surgery is the last choice only when conservative treatment fails. In this case we aimed to present a late onset of chylous ascites after subtotal gastrectomy and D1+ dissection that was treated with percutaneous drainage and conservative management.

    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.

    Full Text Available Objective: to evaluate the effect of the Euphorbia tirucalli hydroalcoholic extract (ETHE on the development of Ehrlich Tumor, in its ascitic form. Methods: we intraperitoneally inoculated 15 Swiss mice with 10.44 x 107 cells of Ehrlich Tumor and divided them in two groups one day after: ETHE Group (eight mice, treated with a dosage of 125 mg/kg/day of EHTE for five days; and Control Group (seven mice, treated only with 0.9% isotonic saline solution over the same period. The treatment was done by gavage. Ten days after inoculation, four mice from each group were sacrificed for quantification of tumor cell number, ascitic fluid volume and bone marrow cell number. The remaining animals were maintained to evaluate survival. Results: The ascitic fluid volume and the tumor cell number were decreased in the ETHE group when compared with the control group, but with no statistical significance. On the other hand, survival was higher in the ETHE group, as well as the number of bone marrow cells. Conclusion: Treatment with ETHE after inoculation of Ehrlich Tumor decreases its development and increases survival and the bone marrow cellularity, thus reducing the myelosuppression present in the Ehrlich Tumor bearing mice.

    To determine through an analysis of the location of pleural effusion associated with ascites, as seen on abdominal CT scan, differences in the distribution of pleural effusion according to the etiology and distribution of ascites. We retrospectively evaluated 77 consecutive patients in whom abdominal CT scan revealed pleural effusion associated with ascites. Patients with history of surgery or trauma and those with clinically and radiologically diagnosed lung or pleural diseases were excluded. We compared the location of pleural effusion with the etiology and distribution of ascites. Forty-two patients were suffering from hepatobiliary diseases, mainly right dominant pleural effusion (26/42, 62%). Fourteen had intraperitoneal carcinomatosis with no significant difference between the frequency of right dominant (5/14, 36%) and of left dominant (6/14, 43%) pleural effusion. Eleven patients had pancreatic diseases, with mainly left dominant pleural effusion (6/11, 55%). Patients with right dominant ascites usually had right dominant pleural effusion (22/24, 92%) and those with left dominant ascites had left dominant pleural effusion (9/10, 90%). Ascites-associated pleural effusion correlated with the anatomical location of the etiology of ascites; its laterality was, in addition, usually the same as that of ascites.

    Full Text Available Posttransplant lymphoproliferative disorder (PTLD is a spectrum of diseases that involves abnormal lymphoid and/or plasmacytic proliferation in patients with solid organ or hematopoietic cell transplantation. It is a condition with a low incidence of 3.5–4.3% in liver transplant (LT recipients. This case involves a 63-year-old male with history of LT for chronic HCV induced cirrhosis who presented with abdominal distension related to worsening ascites. Cytological ascitic fluid analysis revealed EBV (+ malignant cells without a malignant focal point on imaging. Diagnosis of monomorphic PTLD with primary effusion lymphoma-like morphology and immunophenotype was established. This case highlights the complexity in diagnosis, different diagnostic modalities, and rare clinical presentations of PTLD.

    A 2.5-year-old spayed female American Pit Bull Terrier dog presented with a primary complaint of chronic refractory ascites. The dog's CBC displayed a moderate to severe macrocytic, hypochromic, nonregenerative anemia, and a moderate leukopenia as result of a moderate neutropenia and monocytopenia. Microscopic examination of the blood smear showed marked anisocytosis, mild polychromasia, mild acanthocytosis and ovalocytosis, moderate schistocytosis and poikilocytosis, and 4 metarubricytes/100 WBC. Abdominal ultrasonography revealed a homogenous, mild to moderately hyperechoic appearing liver as well as marked amounts of speckled anechoic to slightly hypoechoic peritoneal fluid. Cytology of the ascitic fluid demonstrated a sterile transudate, with evidence of a chronic inflammatory reaction as well as erythroid and myeloid precursor cells, and a few megakaryocytes with occasional micromegakaryocytes. Histologic sections of bone marrow, spleen, and liver were examined, using routine H&E stains, as well as a variety of immunohistochemistry and other special stains. Histopathology of the bone marrow and spleen revealed varying degrees of fibrosis, erythroid, and myeloid hyperplasia, as well as multiple small hyperplastic clusters of megakaryocytes. The megakaryocytes displayed many features of atypia such as increased cytoplasmic basophilia and occasional abnormal chromatin clumping with mitoses. Histopathologic examination of the liver disclosed evidence of mild extramedullary hematopoiesis. This case represents the first report of canine idiopathic myelofibrosis associated with peritoneal extramedullary hematopoiesis, resulting in refractory ascites. Although idiopathic myelofibrosis is a relatively rare condition in dogs, this case demonstrates that ascites caused by peritoneal implants of hematopoietic tissue may be the initial manifestation of myelofibrosis. © 2016 American Society for Veterinary Clinical Pathology.

    Full Text Available Clinicopathological studies on the effects of combining immunostimulant drugs (levamisole with anti-cancer drugs (chlorambucil revealed the enhancement of the latter against Ehrlich ascites carcinoma-bearing mice and resulted in a reduction in the size of tumour. An evaluation of liver and kidney functions showed a significant increase of alanine transaminase (ALT, aspartate transaminase (AST and creatinine in all groups. Histopathological studies of one group that received an intraperitoneal injection of Ehrlich ascites carcinoma cells (2.5 × 106 showed that hepatic parenchyma revealed degenerative changes. The portal area was oedematous and showed rounded cell aggregations. Cell death within hypertrophied Kupper cells was observed in some hepatic cells. The neoplastic emboli could be seen either inside blood vessels or hepatic sinusoids, while another group which had been treated orally with a combination of Leukeran™ (0.2 mg/kg body weight and levamisole (5 mg/kg body weight revealed that hepatic parenchyma revealed massive necrosis with proliferative bile duct epithelium. No neoplastic cells were observed without the hepatic parenchyma, while the renal cortex presented a large number of lymphocytes and plasma cells forming bands or aggregates, mainly around the blood vessels. It was concluded that the addition of levamisole to chlorambucil improved the anti-cancer effect of chlorambucil against Ehrlich ascites carcinoma. However, it had adverse effects on the liver and kidneys as shown by liver and kidney function tests and confirmed by histopathology.

    2015-10-21

    Malignant ascites affects approximately 10% of patients with gastric cancer (GC), and poses significant difficulties for both patients and clinicians. In addition to the dismal general condition of affected patients and the diversity of associated complications such as jaundice and ileus, problems in assessing scattered tumors have hampered the expansion of clinical trials for this condition. However, the accumulation of reported studies is starting to indicate that the weak response to treatment in GC patients with malignant ascites is more relevant to their poor prognosis rather than to the ascites volume at diagnosis. Therefore, precise assessment of initial state of ascites, repetitive evaluation of treatment efficacy, selection of suitable treatment, and swift transition to other treatment options as needed are paramount to maximizing patient benefit. Accurately determining ascites volume is the crucial first step in clinically treating a patient with malignant ascites. Ultrasonography is commonly used to identify the existence of ascites, and several methods have been proposed to estimate ascites volume. Reportedly, the sum of the depth of ascites at five points (named "five-point method") on three panels of computed tomography images is well correlated to the actual ascites volume and/or abdominal girth. This method is already suited to repetitive assessment due to its convenience compared to the conventional volume rendering method. Meanwhile, a new concept, "Clinical Benefit Response in GC (CBR-GC)", was recently introduced to measure the efficacy of chemotherapy for malignant ascites of GC. CBR-GC is a simple and reliable patient-oriented evaluation system based on changes in performance status and ascites, and is expected to become an important clinical endpoint in future clinical trials. The principal of treatment for GC patients with ascites is palliation and prevention of ascites-related symptoms. The treatment options are various, including a

    Full Text Available Abstract Introduction Chylous ascites may result from diverse pathologies. Ascites results either due to blockage of the lymphatics or leak secondary to inadvertent trauma during surgery. Case presentation We report the first case of chylous ascites following radical nephrectomy for a renal cell carcinoma involving the right half of a crossed fused renal ectopia. The patient was managed conservatively. Conclusion Post-operative chylous ascites is a rare complication of retroperitoneal and mediastinal surgery. Most cases resolve with conservative treatment which aims at decreasing lymph production and optimizing nutritional requirements along with palliative measures. Refractory cases need either open or laparoscopic ligation of the leaking lymphatic channels. A review of the current literature on the management of post-operative chylous ascites is presented.

    Abstract 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.

  10. Bile Acid Metabolism and Signaling

    Chiang, John Y. L.

    2015-01-01

    Bile acids are important physiological agents for intestinal nutrient absorption and biliary secretion of lipids, toxic metabolites, and xenobiotics. Bile acids also are signaling molecules and metabolic regulators that activate nuclear receptors and G protein-coupled receptor (GPCR) signaling to regulate hepatic lipid, glucose, and energy homeostasis and maintain metabolic homeostasis. Conversion of cholesterol to bile acids is critical for maintaining cholesterol homeostasis and preventing accumulation of cholesterol, triglycerides, and toxic metabolites, and injury in the liver and other organs. Enterohepatic circulation of bile acids from the liver to intestine and back to the liver plays a central role in nutrient absorption and distribution, and metabolic regulation and homeostasis. This physiological process is regulated by a complex membrane transport system in the liver and intestine regulated by nuclear receptors. Toxic bile acids may cause inflammation, apoptosis, and cell death. On the other hand, bile acid-activated nuclear and GPCR signaling protects against inflammation in liver, intestine, and macrophages. Disorders in bile acid metabolism cause cholestatic liver diseases, dyslipidemia, fatty liver diseases, cardiovascular diseases, and diabetes. Bile acids, bile acid derivatives, and bile acid sequestrants are therapeutic agents for treating chronic liver diseases, obesity, and diabetes in humans. PMID:23897684

    Significant delay in the washout of intraperitoneal xenon ( 133 Xe) in rats and dogs with decreased splanchnic blood flow (bowel strangulation, superior mesenteric artery and vein occlusion) has been previously demonstrated as the basis for radionuclide imaging to detect early (prenecrotic) intestinal ischemia. In this study, the effect of ascites, adhesions, and misdirected injections on the validity of this technique is evaluated. Xenon-133 (0.6 mCi) in 3 ml saline was injected into the peritoneal cavity of anesthetized rats and the washout of gamma activity monitored externally for 90 min. Gamma camera images were obtained at 30-min intervals. After 60 min, only 12 +/- 2% of injected activity remained in the controls. Sham option (13 +/- 1%) and simple obstruction (12 +/- 2) had been previously shown not to significantly slow washout, but segmental strangulation had done so dramatically (32 +/- 2%, P less than 0.0001). In these experiments, ascitic fluid (Ringer's lactate) in volumes of 10 ml (13 +/- 1%), 20 ml (13 +/- 1%), and 40 ml (13 +/- 1%), did not significantly slow washout in nonischemic rats. Sixty and eighty milliliters produced very tense ascites and slight but significant delay in washout (14 +/- 1%, 17 +/- 1%, respectively, P less than 0.05). Moderate (11 +/- 1%) and severe (11 +/- 1%) adhesions produced by serosal scarification did not delay washout nor affect imaging. Injections of isotope intentionally misdirected into the abdominal wall (32 +/- 2%), bowel wall (18 +/- 1%), and bowel lumen (19 +/- 2%), each significantly (P less than 0.001) slowed washout. However, such misdirected injections were easily recognizable as such on the 1-min gamma camera images and could thereby be excluded as artifactual. It is concluded that the intraperitoneal xenon technique is not invalidated by mild to moderate ascites nor by moderate to severe adhesions

    Objective: To assess the clinical efficacy of TIPS in the treatment of patients with refractory ascites and investigate the clinical factors associated with TIPS. Methods: 21 consecutive patients with refractory ascites, 16 men and 5 women with mean age of 45 years (range 22-69 years) were followed up for an average of 337 days (range 50-1323 days). Ascites/abdomen circumference, serum parameters, stents function, time of followed up and survival rate were analyzed. Results: The ascites was significantly reduced as compared with basal values (P<0.05). 81% and 91% patients had no or mild ascites during 3 to 6 months and 9 to 12 after TIPS respectively. According to responses to treatment within 3 months, using Logistic regression predicated the control of ascites with relation to Child class C for severe prognosis (P<0.05). There were significant change in serum sodium, serum creatinine as compared with baseline at follow-up (P<0.05). Their mortality were 14% during follow-up for 3 months, 20% in 6 and the survival rate was 72% at 1 year. According to COX regression analysis showed that age, Child class C, serum albumin, hepatic encephalopathy, serum total bilirubin were related to severe prognosis; but only hepatic encephalopathy and Child class C had an effect on survival rate. Conclusion: TIPS is an effective method for refractory ascite caused by hepatitis cirrhosis, and also effective for patients with functional renal failure but retaining of liver compensation

    The paper presents an experimental study of pathological human bile taken from the gallbladder and bile ducts. The flow dependences were obtained for different types of bile from patients with the same pathology, but of different age and sex. The parameters of the Casson's and Carreau's equations were found for bile samples. Results on the hysteretic bile behavior at loading-unloading tests are also presented, which proved that the pathologic bile is a non-Newtonian thixotropic liquid. The viscosity of the gallbladder bile was shown to be higher compared to the duct bile. It was found that at higher shear stress the pathological bile behaves like Newtonian fluid, which is explained by reorientation of structural components. Moreover, some pathological bile flow in the biliary system CFD simulations were performed. The velocity and pressure distributions as well as flow rates in the biliary segments during the gallbladder refilling and emptying phases are obtained. The results of CFD simulations can be used for surgeons to assess the patient's condition and choose an adequate treatment.

    It has been known from previous studies that body fluids, such as cerebrospinal fluid, lung surfactant, and urine, have a strong impact on the bacterial killing of many anti-infective agents. However, the influence of human bile on the antimicrobial activity of antibiotics is widely unknown. Human bile was obtained and pooled from 11 patients undergoing cholecystectomy. After sterilization of the bile fluid by gamma irradiation, its effect on bacterial killing was investigated for linezolid (LZD) and tigecycline (TGC) against Enterococcus faecalis ATCC 29212. Further, ciprofloxacin (CIP), meropenem (MEM), and TGC were tested against Escherichia coli ATCC 25922. Time-kill curves were performed in pooled human bile and Mueller-Hinton broth (MHB) over 24 h. Bacterial counts (in CFU per milliliter after 24 h) of bile growth controls were approximately equal to MHB growth controls for E. coli and approximately 2-fold greater for E. faecalis , indicating a promotion of bacterial growth by bile for the latter strain. Bile reduced the antimicrobial activity of CIP, MEM, and TGC against E. coli as well as the activity of LZD and TGC against E. faecalis This effect was strongest for TGC against the two strains. Degradation of TGC in bile was identified as the most likely explanation. These findings may have important implications for the treatment of bacterial infections of the gallbladder and biliary tract and should be explored in more detail.

    We measured plasma bile acids, markers of bile acid synthesis, and expression of bile acid transporters in obese and nonobese subjects. We found that obesity was associated with increased bile acid synthesis and 12-hydroxylation, blunted response of plasma bile acids to insulin infusion or a mixed meal, and decreased expression of liver bile acid transporters.

    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.

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Portal hypertension induces a splanchnic and systemic low-grade inflammatory response that could induce the expression of three phenotypes, named ischemia-reperfusion, leukocytic, and angiogenic phenotypes.During the splanchnic expression of these phenotypes, interstitial edema, increased lymph flow, and lymphangiogenesis are produced in the gastrointestinal tract. Associated liver disease increases intestinal bacterial translocation, splanchnic lymph flow, and induces ascites and hepatorenal syndrome. Extrahepatic cholestasis in the rat allows to study the worsening of the portal hypertensive syndrome when associated with chronic liver disease. The splanchnic interstitium, the mesenteric lymphatics, and the peritoneal mesothelium seem to create an inflammatory pathway that could have a key pathophysiological relevance in the production of the portal hypertension syndrome complications. The hypothetical comparison between the ascitic and the amniotic fluids allows for translational investigation. From a phylogenetic point of view, the ancestral mechanisms for amniotic fluid production were essential for animal survival out of the aquatic environment. However, their hypothetical appearance in the cirrhotic patient is considered pathological since ultimately they lead to ascites development. But, the adult human being would take advantage of the potential beneficial effects of this “amniotic-like fluid” to manage the interstitial fluids without adverse effects when chronic liver disease aggravates.

    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.

    2002-01-01

    Full Text Available OBJECTIVE: To evaluate the clinical meaning of ascites and the main features of patients with ascites and endomyocardial fibrosis. METHODS: We studied 166 patients with endomyocardial fibrosis (mean age 37 years, 114 women treated over the last 20 years. Ventriculography findings, surgery or necropsy confirmed the diagnosis in all patients. Most patients belonged to New York Heart Association Functional Class III/IV (134, 83.7%. Eighty-one (50.6% had biventricular, 28 (17.5% had right ventricular, and 51 (31.8% had left ventricular involvement. During follow-up, 56 patients died. RESULTS: Ascites was present in 67 (41.8% patients, and right ventricular involvement was present in 59 (88%. In the comparison between patients with or without ascites, those with ascites had higher mortality (49.2% and 24.7%, respectively. Patients with ascites had a higher incidence of edema (95% vs. 43%, hepatomegaly (5.8cm vs. 4.1cm, mean right atrium pressure (19.3 vs. 12mmHg, and final right ventricle diastolic pressure (18.7 vs. 12.9mmHg. Also, patients with ascites had a longer history of illness (5.1 and 3.9 years, respectively and had atrial fibrillation more frequently (44.7% vs. 30.1%. CONCLUSION: Ascites was observed in less than 50% of cases of endomyocardial fibrosis and was associated with greater involvement of the right ventricle and with a longer duration of the disease, thus being a characteristic of a worse prognosis.

    The cause of the chylous ascites in infants isn't completely clear. The purpose of this study is to discuss our experience of recognition of intestinal malrotation as a cause of congenital chylous ascites in infants. Medical information of 10 infants with chylous ascites, who were admitted to the hospital between 2001 and 2014, was retrospective analyzed. Preoperatively, all patients underwent a period of conservative treatment. We found that nine of ten patients with intestinal malrotation, six of them underwent laparoscopic Ladd's procedure and three patients underwent open Ladd's procedure. The remaining one patient suffered from mesenteric lymph nodes rupture and laparoscopic resection was performed. The cylous ascites subsided in all patients after the surgery and no significant recurrence was encountered during follow-up time. Our study demonstrates that congenital chylous ascites could be caused by intestinal malrotation, causing the obstruction of the lymphatic flow in the mesenteric lymphatic channels. Ladd's procedure maybe a safe and effective treatment for infantile intractable chylous ascites. Treatment study. Level IV. Copyright © 2017 Elsevier Inc. All rights reserved.

    Chylous ascites is a rare complication following pancreaticoduodenectomy. We report on a case of chylous ascites following pancreaticoduodenectomy in a 76-year-old patient diagnosed with pancreatic cancer. There are various known conservative management strategies, including dietary measures or total parenteral nutrition. Unfortunately, conservative treatment - with total parenteral nutrition and fasting over a period of 4 weeks - was not successful in the present case. The daily output volume of chylous ascites was up to 2500 ml/day. Based on clinical experiences with successfully treated lymphocutaneous fistulas, low-dose radiotherapy was initiated. External beam radiotherapy comprising a total dose of 8.0 Gy to the paraaortic lymph node region was administered in daily single fractions of 1.0 Gy (five fractions/week). Throughout the course of external beam radiotherapy, the secretion of abdominal ascites rapidly decreased, resulting in complete resolution after 2 weeks. There was no clinical evidence of chylous ascites on follow-up. As a result of this experience, we believe that external beam radiotherapy should be considered as an alternative therapy in refractory cases of chylous ascites. (orig.) [de

    Unscheduled DNA synthesis (UDS), an indicator of excision repair, was induced in freshly drawn Ehrlich ascites tumor cells (EAT), using ionizing radiation, far ultraviolet light (254 nm) or near uv light (365 nm) in combination with 8-methoxypsoralen. UDS was scored by grain counts in autoradiographs following the incorporation of tritium-labelled thymidine. The amount of UDS after each of these agents was expressed in terms of two parameters, viz. numer of cells showing repair and the mean number of grains per nucleus. The influence of radiation dose and of the duration of radioactive thymidine incubation were also examined. To test for a possible relationship between low mitotic index and repair capability, EAT cells were incubated in buffered salt media to lower the mitotic index. Cells kept in a buffered salt solution for 7 h show a marked drop in mitotic index compared to those incubated in minimal medium containing 15% fetal calf serum (MEM + FCS). This drop in mitotic index was reversible for up to 5 h, if cells were returned to MEM + FCS. Cells incubated in MEM + FCS also showed a decrease in mitotic activity compared to freshly drawn cells. This reduced mitotic index is approximately constant for up to 24 h. With the drop in mitotic index, EAT cells also show a drop in repair compared to freshly drawn cells. The repair capability of cells incubated in buffer can be restored by returning cells to MEM + FCS

    2018-01-01

    Bile acids facilitate intestinal nutrient absorption and biliary cholesterol secretion to maintain bile acid homeostasis, which is essential for protecting liver and other tissues and cells from cholesterol and bile acid toxicity. Bile acid metabolism is tightly regulated by bile acid synthesis in the liver and bile acid biotransformation in the intestine. Bile acids are endogenous ligands that activate a complex network of nuclear receptor farnesoid X receptor and membrane G protein-coupled bile acid receptor-1 to regulate hepatic lipid and glucose metabolic homeostasis and energy metabolism. The gut-to-liver axis plays a critical role in the regulation of enterohepatic circulation of bile acids, bile acid pool size, and bile acid composition. Bile acids control gut bacteria overgrowth, and gut bacteria metabolize bile acids to regulate host metabolism. Alteration of bile acid metabolism by high-fat diets, sleep disruption, alcohol, and drugs reshapes gut microbiome and causes dysbiosis, obesity, and metabolic disorders. Gender differences in bile acid metabolism, FXR signaling, and gut microbiota have been linked to higher prevalence of fatty liver disease and hepatocellular carcinoma in males. Alteration of bile acid homeostasis contributes to cholestatic liver diseases, inflammatory diseases in the digestive system, obesity, and diabetes. Bile acid-activated receptors are potential therapeutic targets for developing drugs to treat metabolic disorders. PMID:29325602

    2015-01-01

    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 57-year-old male with obstructive jaundice was diagnosed extrahepatic bile duct carcinoma at bifurcation by percutaneous transhepatic cholangiography (PTC). He was treated 3,300 rad of external irradiation and then intraluminal irradiation using the Iridium-192 wire by two times with the aid of PTC internal drainage, each was given by the dose of 1,600 rad at 5 mm inside the tumor from the PTC-tube. He had been well for about 1 year and then died because of ascites and cachexia. Autopsy revealed only microscopic tumor cells remaining around the common duct below the cystic junction. It was confirmed that intraluminal irradiation using the Iridium-192 wire was potentially curable and easily applicable to the bile duct carcinoma.

This study was planned to determine the clinical presentation, study different diagnostic modalities, treatment and outcome of patients with spontaneous perforation of bile duct. Methods: This descriptive case series, comprising 22 patients with spontaneous perforation of bile duct over a period of 24 months. Clinical presentation, biochemical abnormalities, imaging details, treatment options and outcome were studied. Results: Total 22 patients (12 Males and 10 Females) between ages of 1.5-36 months were studied. Associated anatomical defects included choledochal cyst in 7 (31.8%) while acquired biliary atresia in 1 (4.5%). Elevated liver enzymes (ALT and AST) were present in 16 patients (72.7%) and 5 (22.7%) had bilirubin above 3 mg/dl. Coagulopathy was seen in 8 (36.6%) patients. Abdominal USG showed presence of ascites in all 22 (100%), hydrocele in 2 (9.0%), inguinal hernia in 1 (4.5%), choledochal cyst in 7 (31.8%) and atretic gall bladder suggestive of acquired biliary atresia in one (4.5%) patient. HIDA scan was diagnostic in all 17 (77.27%) in which it was performed. MRCP was done in 3 (13.6%) patients. Mortality frequency was 3/22 (13.6%); one died of post-surgical sepsis second one was cirrhotic at time of presentation and didnot make It. Two were lost to follow up one which died at home while we lost contact with fourth patient. Conclusion: Spontaneous perforation of bile duct can present and should be suspected as an important cause of neonatal biliary ascites or peritonitis. Most patients can be managed with intravenous antibiotics, percutaneous drainage and t-tube insertion while patients with choledochal cysts required cholecystectomy with roux en y choledochjejunostomy. Timely recognition and intervention is associated with favourable outcome. (author)

    Background & Aims Algorithms for diagnosis of malignant common bile duct (CBD) stenoses are complex and lack accuracy. Malignant tumors secrete large numbers of extracellular vesicles (EVs) into surrounding fluids; EVs might therefore serve as biomarkers for diagnosis. We investigated whether...... concentrations of EVs in bile could discriminate malignant from nonmalignant CBD stenoses. Methods We collected bile and blood samples from 50 patients undergoing therapeutic endoscopic retrograde cholangiopancreatography at university hospitals in Europe for CBD stenosis of malignant (pancreatic cancer, n = 20...... with a diagnosis of pancreatic cancer, based on tissue analysis, and 10 consecutive controls. Using samples from these subjects, we identified a threshold concentration of bile EVs that could best discriminate between patients with pancreatic cancer from controls. We verified the diagnostic performance of bile EV...

    To determine the most useful sonographic technique to evaluate pleural effusion and ascites by comparing conventional, tissue harmonic and pulse inversion harmonic images. 12 patients having pleural effusion and 14 patients having ascites were included in this study. 18 patients were male and 8 patients were female. Average age was 54.8 yrs (25-77). We compared images which had been taken at the same section with 3 above mentioned sonographic techniques. Evaluation was done by 3 radiologists in consensus and grades were given to 3 techniques from 1 to 3. Evaluating points were 1) normal structures that border the fluid such as liver, peritoneal lining, pleura, 2) septation in fluid, 3) debris floating in fluid, and 4) artifacts. Pulse inversion harmonic image was the best in image quality for normal structures, followed by tissue harmonic and conventional image (p<0.05). Pulse inversion harmonic image was better than conventional image to evaluate septation in fluid (p<0.05), but there were no statistically significant difference between pulse inversion and tissue harmonic images, and tissue harmonic and conventional images. Tissue harmonic image was better than pulse inversion harmonic and conventional images to evaluate debris floating in fluid (p<0.05) but there was no statistically significant difference between these two latter techniques. Artifacts were most prominent on conventional image followed by tissue harmonic and pulse inversion harmonic image (p<0.05). Pulse inversion harmonic image was the best sonographic technique to evaluate pleural effusion or ascites, However, Tissue harmonic image was the best for evaluation of debris.

    The mammalian biliary system, consisting of the intrahepatic and extrahepatic bile ducts, is responsible for transporting bile from the liver to the intestine. Bile duct dysfunction, as is seen in some congenital biliary diseases such as Alagille syndrome and biliary atresia, can lead to the accumulation of bile in the liver, preventing the excretion of detoxification products and ultimately leading to liver damage. Bile duct formation requires coordinated cell-cell interactions, resulting in...

    OBJECTIVE: It is currently discussed if beta-blockers exert harmful effects and increase mortality in patients with cirrhosis and refractory ascites. In this study, we provide an overview of the available literature in this field in combination with a retrospective analysis of 61 patients...... trials (9 trials on propranolol, 1 case-control study and 4 retrospective analyses) were identified. One trial suggested an increased mortality in patients treated with beta-blockers and refractory ascites. The results of the remaining trials were inconclusive. No increase in mortality among beta-blocker......-treated patients was found in the present retrospective analysis. CONCLUSIONS: Treatment with beta-blockers may increase mortality in patients with cirrhosis and refractory ascites. However, the current evidence is sparse and high-quality studies are warranted to clarify the matter....

    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.

    Full Text Available Abstract Introduction Ovarian cancer ascitic fluid, which contains malignant cells, is usually present in women with an advanced stage disease. There are currently no effective therapies for the treatment of ovarian cancer ascitic fluid. We developed a new therapeutic strategy to target expression of the diphtheria toxin fragment A gene in ovarian tumor cells under the control of H19 regulatory sequences. Case presentation A 64-year-old Caucasian woman was diagnosed with a stage IIIc epithelial ovarian cancer. She suffered from progressive disease, accumulation of malignant ascites that needed to be drained weekly, abdominal pain, vomiting, anorexia and severe weakness. Infusion of the diphtheria toxin A chain-H19 plasmid into the peritoneum of our patient resulted in complete resolution of the ascites with minimum adverse events. Conclusion On the basis of this preliminary experience, we are currently conducting an extensive Phase I study on a larger number of patients in order to assess the safety and preliminary efficacy of this novel patient-oriented treatment approach.

    In a previous work, bile-salt-resistant derivatives were obtained from non-intestinal lactobacilli. The aim of this work was to investigate the impact of bile adaptation of Lactobacillus delbrueckii subsp. lactis 200 on morphology, surface properties, in vivo interaction capacity with the gut and ability to activate the gut immune response. Electron microscopy studies, growth kinetics in the presence of bovine and porcine bile, the capacity to deconjugate bile acids, hydrophobicity, autoaggregation and co-aggregation capacities were studied for the parental strain and its bile-resistant derivative in vitro. Additionally, survival in intestinal fluid, the interaction with the gut and the immunomodulating capacities were studied in mice. Bile salt adaptation conferred upon the adapted strain a higher capacity to withstand physiological concentrations of bile salts and greater survival capacity in intestinal fluid. However, bile salt exposure reduced cell hydrophobicity, autoaggregation and adhesion capacities, resulting in reduced persistence in the intestinal lumen and delayed capacity to activate the gut immune response. Insight into the effects of bile salts upon the interaction and immunomodulating capacity of lactobacilli with the gut is provided, relating in vitro and in vivo results.

  16. Observations on the mechanism and location of ascites reabsorption in man

    International Nuclear Information System (INIS)

    Rector, W.G. Jr.; Ibarra, F.

    1987-01-01

    Animal data indicate that ascites is reabsorbed by a lymphatic mechanism and that these vessels are subdiaphragmatic in location. We evaluated the relative role of lymphatics in ascites reabsorption in man by comparing the ascites clearance and plasma appearance rates of intraperitoneally injected radiolabeled albumin to those of intraperitoneally injected labeled autologous red blood cells, which require, owing to their large size, lymphatic removal, in patients with cirrhosis and ascites. To evaluate the location of reabsorption, we repeated these measurements after replacing ascites in the subdiaphragmatic region with 500-1000 ml of intraperitoneally injected air, reasoning that this maneuver should slow or eliminate ascites reabsorption occurring at this site. We found that the transfer rates of albumin and red cells out of ascites were similar and that creation of pneumoperitoneum did not influence these rates. These data confirm that ascites protein reabsorption occurs via a lymphatic mechanism in man. They suggest, however, that these vessels may not be subdiaphragmatic in location

    Chylous ascites is a rare complication following pancreaticoduodenectomy. We report on a case of chylous ascites following pancreaticoduodenectomy in a 76-year-old patient diagnosed with pancreatic cancer. There are various known conservative management strategies, including dietary measures or total parenteral nutrition. Unfortunately, conservative treatment - with total parenteral nutrition and fasting over a period of 4 weeks - was not successful in the present case. The daily output volume of chylous ascites was up to 2500 ml/day. Based on clinical experiences with successfully treated lymphocutaneous fistulas, low-dose radiotherapy was initiated. External beam radiotherapy comprising a total dose of 8.0 Gy to the paraaortic lymph node region was administered in daily single fractions of 1.0 Gy (five fractions/week). Throughout the course of external beam radiotherapy, the secretion of abdominal ascites rapidly decreased, resulting in complete resolution after 2 weeks. There was no clinical evidence of chylous ascites on follow-up. As a result of this experience, we believe that external beam radiotherapy should be considered as an alternative therapy in refractory cases of chylous ascites. (orig.)

    Post-hepatectomy bile leak may lead to undesired morbidity. Multiple methods have been employed to identify this leak but can be inconclusive and taxing. This novel white gauze test is a simple and reliable method. This is a prospective study performed from January 2010 until March 2011. All open hepatic resection were included. Dry white gauze is compressed onto the transected surface and observed for bile staining. The leaking duct is repaired immediately upon detection. The process is repeated until negative. Drain was removed on postoperative day-5. Post-operative bile leak is defined as: 1. Bilirubin concentration of the drain fluid is 3 times or higher than serum; 2. Presence of intra-abdominal bile collection on imaging and upon drainage; 3. Bile leak demonstrated on postoperative cholangiography. 42 patients were recruited. Seven (16.7%) patients were cirrhotic with Child-Pugh A. White gauze test were positive for intra-operative bile leaks in 29 patients (70%), which were primarily repaired. As a result, there was no postoperative bile leak in this series. One mortality was detected in this series due to postoperative pancreatic fistula and multi organ failure. The White Gauze Test is a useful method for the prevention of bile leakage after hepatic resection. It is safe, quick and cheap.

    2003-01-01

    To elucidate whether the morphological changes of the thoracic duct are observed in patients with liver cirrhosis and ascites, the thoracic duct was examined at magnetic resonance (MR) lymphography without contrast agent. In 7 healthy volunteers, the thoracic duct was clearly visualized as an intermittent or continuous straight line along the thoracic aorta (its mean diameter was 3.9 mm). In 20 liver cirrhosis without ascites, its mean diameter was 3.6 mm. In 6 liver cirrhosis with refractory ascites, the thoracic duct was visualized as straight or slightly tortuous and slender line (its mean diameter was 2.5 mm). On the other hand, 7 cases with ascites which respond well to the administration of diuretics showed tortuous and dilated thoracic duct (its mean diameter was 4.3 mm). In cases with refractory ascites, mean diameter of the thoracic duct was significantly reduced, compared with the cases without ascites and with ascites that respond well to the administration of diuretics. Thus, it was found that the morphological differences of the thoracic duct depend on the response to the diuretics in liver cirrhosis patients with ascites. To elucidate whether the morphological changes of the thoracic duct are observed in patients with liver cirrhosis and ascites, the thoracic duct was examined at magnetic resonance lymphography without contrast agent. In cases with refractory ascites, mean diameter of the thoracic duct was significantly reduced, compared with the cases without ascites and with ascites that respond well to the administration of diuretics.

    2018-05-05

    Passive drainage systems are commonly used after subdural hematoma evacuation but there is a dearth of published data regarding the suction forces created. We set out to quantify the suction forces generated by a passive drainage system. We created a model of passive drainage after subdural hematoma evacuation. We measured the maximum suction force generated with a bile bag drain for both empty drain tubing and fluid-filled drain tube causing a siphoning effect. We took measurements at varying heights of the bile bag to analyze if bile bag height changed suction forces generated. An empty bile bag with no fluid in the drainage tube connected to a rigid, fluid-filled model creates minimal suction force of 0.9 mmHg (95% CI 0.64-1.16 mmHg). When fluid fills the drain tubing, a siphoning effect is created and can generate suction forces ranging from 18.7 to 30.6 mmHg depending on the relative position of the bile bag and filled amount of the bile bag. The suction forces generated are statistically different if the bile bag is 50 cm below, level with or 50 cm above the experimental model. Passive bile bag drainage does not generate significant suction on a fluid-filled rigid model if the drain tubing is empty. If fluid fills the drain tubing then siphoning occurs and can increase the suction force of a passive bile bag drainage system to levels comparable to partially filled Jackson-Pratt bulb drainage.

    Full Text Available Abstract Background Although the WHO guideline for the management of dengue fever considers the presence of ascites or pleural effusions in the diagnosis of DSS, it does not emphasize the importance of their presence when selecting fluids for resuscitation. Case presentation We highlight three patients with DSS who received boluses of crystalloids on priority basis as recommended by WHO guidelines during resuscitation. All three patients had varying degrees of third space fluid loss (ascites and pleural effusions at the time of development of DSS. Ascites and pleural effusions were detected in all 3 patients at the time of shock irrespective of whether iv fluids were given or not. All three patients had documented liver involvement at the time of shock evidenced by elevation of AST (4800 iu/L, 5000 iu/L and 1960 iu/L. One patient who had profound shock died 6 hours after admission with evidence of acute pulmonary oedema in the convalescence phase. All of them needed CPAP ventilator support and potent diuretics. Conclusions We therefore feel that resuscitation of patients with DSS who already have third space fluid accumulation with crystalloid boluses on priority basis may contribute to recovery phase pulmonary oedema.

    The effect of Misonidazole on radiosensitivity of Ehrlich ascites tumor cells was studied in vivo. Ehrlich ascites tumor cells growing intraperitoneally (ICR/SIC mice) for either 1, 4, 6 or 10 days were irradiated in vivo (whole body irradiation) with or without Misonidazole. Immediately after irradiation tumor cells were transplanted intraperitoneally into new animals. Four days later, the propagated surviving cells were removed and counted for analyses. Enhancement ratio of Misonidazole at the surviving fraction of 0.1 were 1.0 (for 1-day-old), 1.3 (for 4-day-old), 1.9 (for 6-day-old), 1.9 (for 10-day-old) and 2.8 (for anoxic cells) respectively. The gradual increase of the enhancement ratio of the ascites tumore cells during intraperitoneal growth from 1 through 10 days might be attributed to an increase of hypoxic tumor cells. Cytotoxicity was not observed at 0.1 mg per gram body weight of Misonidazole but was at 1 mg per gram body weight of Misonidazole in 6-day-old and 10-day-old Ehrlich ascites tumor cells which were supposed to contain hypoxic cells. These results suggest that Misonidazole may prove an effective radiosensitizer for hypoxic tumor cells. (author)

    Gastroesophageal reflux (GER) and aspiration of bile acids have been implicated as non-alloimmune risk factors for the development of bronchiolitis obliterans syndrome (BOS) after lung transplantation. The aim of our study was to investigate the association between GER and gastric aspiration of bile acids and to establish which reflux characteristics may promote aspiration of bile acids into the lungs and may feature as a potential diagnostic tool in identifying lung transplantation (LTx) patients at risk for aspiration. Twenty-four stable LTx recipients were studied 1 year after transplantation. All patients underwent 24-hour ambulatory impedance-pH recording for the detection of acid (pH acidic (pH 4 to 7) reflux. On the same day, bronchoalveolar lavage fluid (BALF) was collected and then analyzed for the presence of bile acids (Bioquant enzymatic assay). Increased GER was detected in 13 patients, of whom 9 had increased acid reflux and 4 had exclusively increased weakly acidic reflux. Sixteen patients had detectable bile acids in the BALF (0.6 [0.4 to 1.5] micromol/liter). The 24-hour esophageal volume exposure was significantly increased in patients with bile acids compared to patients without bile acids in the BALF. Acid exposure and the number of reflux events (total, acid and weakly acidic) were unrelated to the presence of bile acids in the BALF. However, both nocturnal volume exposure and the number of nocturnal weakly acidic reflux events were significantly higher in patients with bile acids in the BALF. Weakly acidic reflux events, especially during the night, are associated with the aspiration of bile acids in LTx recipients and may therefore feature as a potential risk factor for the development of BOS.

    Spontaneous perforation of common bile duct (CBD) is extremely rare in children, but potentially a fatal disorder that requires an emergency laparotomy. Most of the patients present with insidious symptoms including slowly progressive abdominal distension with accumulation of the ascites, fluctuating mild jaundice, and clay-colored stools. We report a case of surgically confirmed spontaneous perforation of the CBD in a 3-year-old girl who presented with acute abdominal distension with no biliary symptoms or signs, and who showed imaging findings consistent with anomalous pancreaticobiliary ductal union with a focal stenosis in the CBD.

    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.

    External drainage of the common bile duct by placement of a T-tube is a common practice after choledochotomy. This practice may result in the specific complication of bile peritonitis due to leakage after removal of the T-tube. This complication has multiple causes: some are patient-related (corticotherapy, chemotherapy, ascites), and others are due to technical factors (inappropriate suturing of the drain to the ductal wall, minimal inflammatory reaction related to some drain materials). The clinical presentation is quite variable depending on the amount and rapidity of intra-peritoneal spread of of bile leakage. Abdominal ultrasound (US), with US-guided needle aspiration and occasionally Technetium(99) scintigraphy are useful for diagnosis. Traditional therapy consists of surgical intervention including peritoneal lavage and re-intubation of the choledochal fistulous tract to allow for a further period of external drainage. When leakage is walled off and well-tolerated, a more nuanced and less invasive conservative therapy may combine percutaneous drainage with endoscopic placement of a trans-ampullary biliary drainage.

    2009-10-01

    In addition to their roles in facilitating lipid digestion and absorption, bile acids are recognized as important regulators of intestinal function. Exposure to bile acids can dramatically influence intestinal transport and barrier properties; in recent years, they have also become appreciated as important factors in regulating cell growth and survival. Indeed, few cells reside within the intestinal mucosa that are not altered to some degree by exposure to bile acids. The past decade saw great advances in the knowledge of how bile acids exert their actions at the cellular and molecular levels. In this review, we summarize the current understanding of the role of bile acids in regulation of intestinal physiology.

    Bile salts are potent olfactory stimuli in fishes; however the biological functions driving such sensitivity remain poorly understood. We provide an integrative review of bile salts as semiochemicals in fish. First, we present characteristics of bile salt structure, metabolism, and function that are particularly relevant to chemical communication. Bile salts display a systematic pattern of structural variation across taxa, are efficiently synthesized, and are stable in the environment. Bile salts are released into the water via the intestine, urinary tract, or gills, and are highly water soluble. Second, we consider the potential role of bile salts as semiochemicals in the contexts of detecting nearby fish, foraging, assessing risk, migrating, and spawning. Lastly, we suggest future studies on bile salts as semiochemicals further characterize release into the environment, behavioral responses by receivers, and directly test the biological contexts underlying olfactory sensitivity.

    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. A 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 not

    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.

    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

    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

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

    Obstructive jaundice is frequently caused by bile duct strictures. Determination of malignant strictures is crucial for the initiation of appropriate treatment. Cytologic examination of bile drainage fluid is an easy and reproducible method of detecting malignant cells. This method, however, frequently yields indeterminate results, such as atypia or suspicious of malignancy, due to difficulties in differentiating malignancy from benign atypia. Immunocytochemical assessment of p53 expression by cells in bile drainage fluid may enhance the ability to detect malignancy. A total of 139 samples of bile drainage fluid were obtained from 80 patients. Following cytologic examination, the samples were incubated with antibody to p53. The performance of cytology with and without p53 immunocytochemistry was evaluated, with reference to surgical or clinical findings of benign and malignant biliary strictures. Bile drainage cytology alone had a sensitivity of 31.6% and a specificity of 98.4% in the identification of malignant strictures, whereas the combination of p53 immunocytochemistry and bile drainage cytology had a sensitivity of 80.3% and a specificity of 92.1%. P53 immunocytochemistry alone had a sensitivity of 64.5% and a specificity of 92.7% for the identification of malignant strictures in bile drainage samples with atypical cytology, and a sensitivity of 85.0% and a specificity of 100.0% in samples with suspicious of malignancy. The addition of p53 immunocytochemistry to bile drainage cytology can be useful in identifying malignant strictures in samples showing indeterminate results on bile drainage cytology. Diagn.

    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.

    Full Text Available We report two cases of pulmonary hypoplasia due to fetal ascites in symptomatic congenital cytomegalovirus (CMV infections despite fetal therapy. The patients died soon after birth. The pathogenesis of pulmonary hypoplasia in our cases might be thoracic compression due to massive fetal ascites as a result of liver insufficiency. Despite aggressive fetal treatment, including multiple immunoglobulin administration, which was supposed to diminish the pathogenic effects of CMV either by neutralization or immunomodulatory effects, the fetal ascites was uncontrollable. To prevent development of pulmonary hypoplasia in symptomatic congenital CMV infections, further fetal intervention to reduce ascites should be considered.

    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

    CASE DESCRIPTION A 10-week-old 0.73-kg (1.6-lb) castrated male domestic ferret (Mustela putorius furo) was referred for exploratory laparotomy because of pneumoperitoneum and possible septic peritonitis after being bitten by the owner's dog. CLINICAL FINDINGS Abdominal exploration revealed a large laceration of the duodenum, tears of the jejunal mesentery, and 2 small tears in the abdominal wall. Chylous abdominal effusion developed 48 hours after surgery. TREATMENT AND OUTCOME Postoperative care included supportive treatment, analgesia, and antimicrobials. An abdominal drain was placed during the laparotomy and enabled monitoring of abdominal fluid production. Enteral feeding was provided through an esophagostomy tube. The chylous fluid production rapidly decreased after treatment with octreotide was initiated, and the ferret improved. Chyloabdomen resolved after 8 days of hospitalization and medical treatment. CLINICAL RELEVANCE Findings suggested that chylous ascites can potentially develop secondary to blunt abdominal trauma in ferrets. In this ferret, chyloabdomen was successfully treated with octreotide administration and abdominal drainage.

    Cardiac dysfunction has an increased prevalence in diseases complicated by liver cirrhosis such as primary biliary cholangitis and primary sclerosing cholangitis. This observation has led to research into the association between abnormalities in bile acid metabolism and cardiac pathology. Approximately 50% of liver cirrhosis cases develop cirrhotic cardiomyopathy. Bile acids are directly implicated in this, causing QT interval prolongation, cardiac hypertrophy, cardiomyocyte apoptosis and abnormal haemodynamics of the heart. Elevated maternal serum bile acids in intrahepatic cholestasis of pregnancy, a disorder which causes an impaired feto-maternal bile acid gradient, have been associated with fatal fetal arrhythmias. The hydrophobicity of individual bile acids in the serum bile acid pool is of relevance, with relatively lipophilic bile acids having a more harmful effect on the heart. Ursodeoxycholic acid can reverse or protect against these detrimental cardiac effects of elevated bile acids. Copyright © 2018 Elsevier B.V. All rights reserved.

    Occupational and environmental exposure to potassium dichromate (K2Cr2O7), a hexavalent chromium compound, can result in liver damage associated with oxidative stress and mitochondrial dysfunction. The purpose of this study was to evaluate the effect of the antioxidant curcumin (400 mg/kg b.w.) on the K2Cr2O7-induced injury, with special emphasis on ascitic fluid accumulation and oxidative phosphorylation mitochondrial enzymes and the adenosine triphosphate (ATP) levels in isolated mitochondria from livers of rats treated with K2Cr2O7 (15 mg/kg b.w.). Thus, curcumin attenuated the ascites generation, prevented the decrease in the activities of aconitase and F1F0 ATPase, and maintained the ATP levels. The activity of complex II was not completely reestablished by curcumin, whereas complexes III and IV activities were unchanged. © 2014 Wiley Periodicals, Inc.

  18. Intestinal transport and metabolism of bile acids

    2015-01-01

    In addition to their classical roles as detergents to aid in the process of digestion, bile acids have been identified as important signaling molecules that function through various nuclear and G protein-coupled receptors to regulate a myriad of cellular and molecular functions across both metabolic and nonmetabolic pathways. Signaling via these pathways will vary depending on the tissue and the concentration and chemical structure of the bile acid species. Important determinants of the size and composition of the bile acid pool are their efficient enterohepatic recirculation, their host and microbial metabolism, and the homeostatic feedback mechanisms connecting hepatocytes, enterocytes, and the luminal microbiota. This review focuses on the mammalian intestine, discussing the physiology of bile acid transport, the metabolism of bile acids in the gut, and new developments in our understanding of how intestinal metabolism, particularly by the gut microbiota, affects bile acid signaling.

    The self-assembly of biological surfactants in water is an important topic for study because of its relevance to physiological processes. Two common types of biosurfactants are lecithin (phosphatidylcholine) and bile salts, which are both present in bile and involved in digestion. Previous studies on lecithin-bile salt mixtures have reported the formation of short, rodlike micelles. Here, we show that lecithin-bile salt micelles can be further induced to grow into long, flexible wormlike structures. The formation of long worms and their resultant entanglement into transient networks is reflected in the rheology: the fluids become viscoelastic and exhibit Maxwellian behavior, and their zero-shear viscosity can be up to a 1000-fold higher than that of water. The presence of worms is further confirmed by data from small-angle neutron and X-ray scattering and from cryo-transmission electron microscopy (cryo-TEM). We find that micellar growth peaks at a specific molar ratio (near equimolar) of bile salt:lecithin, which suggests a strong binding interaction between the two species. In addition, micellar growth also requires a sufficient concentration of background electrolyte such as NaCl or sodium citrate that serves to screen the electrostatic repulsion of the amphiphiles and to "salt out" the amphiphiles. We postulate a mechanism based on changes in the molecular geometry caused by bile salts and electrolytes to explain the micellar growth.

    Bile is a biological fluid synthesized in the liver, stored and concentrated in the gall bladder (interdigestive), and released into the duodenum after food intake. The microbial populations of different parts of mammal's gastrointestinal tract (stomach, small and large intestine) have been extensively studied; however, the characterization of bile microbiota had not been tackled until now. We have studied, by culture-dependent techniques and a 16S rRNA gene-based analysis, the microbiota present in the bile, gall bladder mucus, and biopsies of healthy sows. Also, we have identified the most abundant bacterial proteins in the bile samples. Our data show that the gall bladder ecosystem is mainly populated by members of the phyla Proteobacteria, Firmicutes, and Bacteroidetes. Furthermore, fluorescent in situ hybridization (FISH) and transmission electron microscopy (TEM) allowed us to visualize the presence of individual bacteria of different morphological types, in close association with either the epithelium or the erythrocytes, or inside the epithelial cells. Our work has generated new knowledge of bile microbial profiles and functions and might provide the basis for future studies on the relationship between bile microbiota, gut microbiota, and health. © 2014 The Authors.

    Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is an emerging disease entity with unfavourable outcome. Our aim was to analyze the microbial spectrum in bile of patients with SSC-CIP and to evaluate the potential impact on the empiric antibiotic treatment in these patients. 169 patients (72 patients with SSC-CIP and 97 patients with primary sclerosing cholangitis (PSC)) were included in a prospective observational study between 2010 and 2013. Bile was obtained during endoscopic retrograde cholangiography (ERC) and microbiologically analyzed. Patients with SSC displayed a significantly different microbiological profile in bile. Enterococcus faecium, Pseudomonas aeruginosa and non-albicans species of Candida were more frequent in SSC compared to patients with PSC (p bile (p = 0.001). The antimicrobial therapy was adjusted in 64% of patients due to resistance or presence of microorganisms not covered by the initial therapy regimen. Patients with SSC-CIP have a distinct microbial profile in bile. Difficult to treat organisms are frequent and an ERC with bile fluid collection for microbiological analysis should be considered in case of insufficient antimicrobial treatment.

    Full Text Available Os programas de melhoramento genético de frangos de corte que buscam máxima velocidade de ganho de peso, alta eficiência alimentar, alta viabilidade, maior rendimento de carcaça e menor deposição de gordura podem desencadear algumas síndromes fisiológicas, dentre as quais destacam-se o estresse calórico, a morte súbita e a ascite. A ascite se enquadra no conceito das síndromes multifatoriais, uma vez que sua manifestação ocorre quando certos fatores genéticos e ambientais atuam em conjunto determinando o processo. As limitações anatômica e fisiológica da circulação sanguínea nos pulmões provocam a síndrome de hipertensão pulmonar (PHS; esta pode provocar grande acúmulo de fluido na cavidade abdominal, quadro este denominado de ascite. Ocorre redução da eficiência da circulação sangüínea, levando as aves à morte por hipóxia, predominantemente no período entre 30 e 40 dias de idade. Uma vez desencadeado o processo ascítico, a ave dificilmente é aproveitada no abate já que a mesma restringe o consumo de alimento, ganhando menos peso. Adicionalmente, a carcaça apresenta aumento do volume da cavidade abdominal e conseqüente congestão dos órgãos internos. A descrição da fisiologia, medidas de avaliação e perspectivas são apresentadas neste trabalho.Poultry genetic breeding programs which look for maximum weight gain, improved feed conversion, high viability, high carcass yield and low fat deposition may cause some physiologic syndromes, for example caloric stress, sudden death and ascites. Ascites is framed in concept of the multifactorial syndromes, once its manifestation happens when certain genetic and environment factors act together, determining the process. Anatomical and physiological limitations in blood circulation in the lungs give rise to pulmonary hypertension syndrome (PHS, producing great fluid accumulation in abdominal cavity, which is denominated ascites. Ascites causes reduction of blood

  8. Effects of endogenous hydrogen peroxide and glutathione on the stability of arsenic metabolites in rat bile

    Trivalent arsenicals such as arsenite (iAs III ), monomethylarsonous acid (MMA III ) and dimethylarsinous acid (DMA III ) are more toxic than analogous pentavalent compounds such as arsenate (iAs V ), monomethylarsonic acid (MMA V ) and dimethylarsinic acid (DMA V ). It has been reported that arsenic-glutathione (As-GSH) complexes such as arsenic triglutathione (ATG) and methylarsenic diglutathione (MADG) are major metabolites in rat bile following intravenous administration of iAs III . Recently, we have shown that both ATG and MADG are unstable and easily hydrolyzed to iAs III and MMA III , respectively, and that MMA III is oxidized to MMA V in bile. In the present study we report the effects of H 2 O 2 and GSH on the stability of As-GSH complexes in rat bile. Male SD rats were injected intravenously with saline or iAs III at a dose of 0.2 or 2.0 mg As/kg body weight, and bile fluid was collected on ice for 30 min. To estimate the stability of As-GSH complexes in bile, ATG or MADG was added to untreated, heat-treated, catalase-treated, or dialyzed bile, and then incubated at 37 deg. C for 10 min. Concentrations of biliary H 2 O 2 and GSH in the higher dose group were 12.6- and 4.5-times higher than the control value, respectively. Exogenously added trivalent arsenicals were oxidized to pentavalent arsenicals in the bile depending on the biliary concentration of H 2 O 2 . Both catalase and dialysis prevented oxidation of trivalent arsenicals to the corresponding pentavalent compounds. Exogenously added GSH stabilized As-GSH complexes in bile. These results suggest that H 2 O 2 converts trivalent arsenicals to less toxic pentavalent arsenicals, whereas GSH prevents hydrolysis of As-GSH complexes and the generation of unconjugated toxic trivalent arsenicals

    A 70-year-old man had undergone pancreaticoduodenectomy due to a distal common bile duct malignancy. After the operation, serous fluid discharge decreased from two drain tubes in the retroperitoneum. Over four weeks, the appearance of the serous fluid changed to a greenish bile color and the patient persistently drained over 300 ml/day. Viewed as bile leak at the choledochojejunostomy, treatment called for endoscopic diagnosis and therapy. Cap-fitted forward-viewing endoscopy demonstrated that the distal tip of a pancreatic drain catheter inserted at the pancreaticojejunostomy site had penetrated the opposite jejunum wall. One of the drain tubes primarily placed in the retroperitoneum had also penetrated the jejunum wall, with the distal tip positioned near the choledochojejunostomy site. No leak of contrast appeared beyond the jejunum or anastomosis site. Following repositioning of a penetrating catheter of the pancreaticojejunostomy, four days later, the patient underwent removal of two drain tubes without additional complications. In conclusion, the distal tip of the catheter, placed to drain pancreatic juice, penetrated the jejunum wall and may have caused localized perijejunal inflammation. The other drain tube, placed in the retroperitoneal space, might then have penetrated the inflamed wall of the jejunum, allowing persistent bile drainage via the drain tube. The results masqueraded as bile leakage following pancreaticoduodenectomy.

    Full Text Available Groove pancreatitis (GP is a very infrequent subtype of chronic pancreatitis affecting the pancreatic-duodenal junction. It usually manifests in middle-aged men with a history of chronic alcoholism, though it has also been described in women and in individuals who do not consume alcohol[1]. Even though the underlying etiology is unclear, chronic alcohol consumption is known to increase the viscosity of the pancreatic juice and exacerbate the inflammatory process[2]. We present a case of GP that posed diagnostic difficulties because it manifested as ascites and duodenal thickening, with pancreatic imaging findings initially normal.

    The concept that host immunization may be achieved by heat-induced antigenic modifications of cancer cells and/or the release of immunogenic products by dead or dying tumor cells following in vitro heating was examined. Ehrlich ascites cells were used, inasmuch as it was claimed that in vitro hyperthermia increased the immunogenicity of these cells. Tumor cell populations of different viability were obtained by heating Ehrlich cells at 42.5 degrees, 45 degrees, or 60 degrees C. Viable and nonviable cells were separated by Ficoll-Hypaque density centrifugation; viable nonreplicating cells were obtained by treatment with mitomycin C. Cell populations of different viability after heating were left to die slowly over 3 days at 37 degrees C. Swiss TO mice were then given injections of the treated cells and/or medium. No survival benefit occurred in mice inoculated with any of these different components and then challenged with viable tumor cells. Injection of irradiated cells, however, did produce host immunity. Similarly, D23 rat hepatoma ascites cells produced host immunity after 15,000 rad but not after heating. The claim that in vitro hyperthermia increases the immunogenicity of tumor cells was not confirmed

    Full Text Available Both cholesterol and triglyceride levels in serum increase progressively during pregnancy. Hypertrigly-ceridemia is a well-recognized cause of acute pancreatitis, while pancreatitis-associated chylous ascites has rarely been reported. We report a 28-year-old female with coexistence of hypertriglyceridemia, acute pancreatitis, and chylous ascites during pregnancy. After emergency cesarean section, she was treated with nil per os, intravenous hydration, antibiotics, and analgesics as required. Due to the development of positive peritonitis 5 days later, an exploratory laparotomy was performed. Surgical interventions included pancreatic necrosec-tomy, right hemicolectomy and ileostomy, cholecystostomy, gastrostomy, and feeding jejunostomy. Postoperative treatment included antibiotics, total parenteral nutrition, and then low-fat diet with medium-chain triglyceride supplementation. She was discharged on the 43rd day after surgery and was free of symptoms during 6 months of follow-up. Ileocolostomy was performed 6 months after discharge. Fasting lipid profile should be regularly monitored during pregnancy due to the association of hypertriglyceridemia with development of acute pancreatitis in the mother.

    1987-01-01

    The effect of 12, 24 and 36 mg/kg body weight doses of fluoro-uracil (5-FU) on the Bp 8 ascites sarcoma growing in vivo was studied. From sequential studies of the total number of cells together with the composition of cells in the cell cycle, the cell cycle flow was calculated and correlated to the pharmacokinetics, which was determined by using 3 He-5-FU. The dose of 12 mg/kg 5-FU affected cell growth between 24 and 72 hours, while the effect of higher doses was immediate. An early block in outflow of cells from G 1 was followed by an increased outflow, indicating an early inhibition followed by an enhancement of the initiation of the DNA synthesis. This increased outflow from G 1 together with the decrease in outflow from the early S-phase, i.e. decreased DNA synthesis, resulted in an accumulation of cells in the early part of the S-phase. The prolonged effects on the cell growth and the cell cycle flow despite the very fast decline in the drug concentration both in the ascites fluid and within the cells, together with a constant level of the drug in the macromolecular fraction, suggest an interaction between 5-FU and RNA/DNA at later times rather than an inhibition of the thymidylate synthetase activity.

    Full Text Available Traumatic bile leaks often result in high morbidity and prolonged hospital stay that requires multimodality management. Data on endoscopic management of traumatic bile leaks are scarce. Our study objective was to evaluate the efficacy of the endoscopic management of a traumatic bile leak. We performed a retrospective case review of patients who were referred for endoscopic retrograde cholangiopancreatography (ERCP after traumatic bile duct injury secondary to blunt (motor vehicle accident or penetrating (gunshot trauma for management of bile leaks at our tertiary academic referral center. Fourteen patients underwent ERCP for the management of a traumatic bile leak over a 5-year period. The etiology included blunt trauma from motor vehicle accident in 8 patients, motorcycle accident in 3 patients and penetrating injury from a gunshot wound in 3 patients. Liver injuries were grade III in 1 patient, grade IV in 10 patients, and grade V in 3 patients. All patients were treated by biliary stent placement, and the outcome was successful in 14 of 14 cases (100%. The mean duration of follow-up was 85.6 days (range 54-175 days. There were no ERCP-related complications. In our case review, endoscopic management with endobiliary stent placement was found to be successful and resulted in resolution of the bile leak in all 14 patients. Based on our study results, ERCP should be considered as first-line therapy in the management of traumatic bile leaks.

    Malignant hemorrhagic ascites may complicate the terminal evolution of digestive cancers with peritoneal carcinomatosis. It has a bad influence on prognosis and may severely impair patients’ quality of life. Palliative laparoscopic hyperthermic intraperitoneal chemotherapy (HIPEC) has been proposed to treat debilitating malignant ascites. Two cases of peritoneal carcinomatosis causing hemorrhagic ascites and severe anemia that needed iterative blood transfusions are reported. These patients were treated by laparoscopic HIPEC (mitomycin C and cisplatin with an inflow temperature of 43°C), resulting in cessation of peritoneal bleeding. No postoperative complication or relapse of ascites occurred during the following months. No more blood transfusion was needed. Laparoscopic HIPEC might be an effective and safe therapeutic option to consider in patients with malignant hemorrhagic ascites. PMID:22679405

    Platinum-based combination therapy is the standard first-line treatment for women with advanced serous epithelial ovarian carcinoma (EOC). However, about 20 % will not respond and are considered clinically resistant. The availability of biomarkers to predict responses to the initial therapy would provide a practical approach to identify women who would benefit from a more appropriate first-line treatment. Ascites is an attractive inflammatory fluid for biomarker discovery as it is easy and minimally invasive to obtain. The aim of this study was to evaluate whether six selected inflammation-regulating factors in ascites could serve as diagnostic or drug resistance biomarkers in patients with advanced serous EOC. A total of 53 women with stage III/IV serous EOC and 10 women with benign conditions were enrolled in this study. Eleven of the 53 women with serous EOC were considered clinically resistant to treatment with progression-free survival < 6 months. Ascites were collected at the time of the debulking surgery and the levels of cytokines were measured by ELISA. The six selected cytokines were evaluated for their ability to discriminate serous EOC from benign controls, and to discriminate platinum resistant from platinum sensitive patients. Median ascites levels of IL-6, IL-10 and osteoprotegerin (OPG) were significantly higher in women with advanced serous EOC than in controls (P ≤ 0.012). There were no significant difference in the median ascites levels of leptin, soluble urokinase plasminogen activator receptor (suPAR) and CCL18 among serous EOC women and controls. In Receiver Operator curve (ROC) analysis, IL-6, IL-10 and OPG had a high area under the curve value of 0.905, 0.832 and 0.825 respectively for distinguishing EOC from benign controls. ROC analysis of individual cytokines revealed low discriminating potential to stratify patients according to their sensitivity to first-line treatment. The combination of biomarkers with the highest discriminating

    Radiation-induced bowel disease manifested by debilitating diarrhea is an unfortunate consequence of therapeutic irradiation for pelvic malignancies. Although the mechanism for this diarrhea is not well understood, many believe it is the result of damage to small bowel mucosa and subsequent bile acid malabsorption. Excess amounts of bile acids, especially the dihydroxy components, are known to induce water and electrolyte secretion and increase bowel motility. We have directly measured individual and total bile acids in the stool samples of 11 patients with radiation-induced diarrhea and have found bile acids elevated two to six times normal in eight of them. Our patients with diarrhea and increased bile acids in their stools had prompt improvement when given cholestyramine. They had fewer stools and returned to a more normal life-style

    Renal dysfunction in cholestatic liver disease is multifactorial. Acute kidney injury may develop secondary to renal vasoconstriction in the setting of peripheral vasodilation and relative hypovolemia, tubular obstruction by bile casts, and direct tubular toxicity from bile. Anabolic steroids are frequently used by athletes to boost endurance and increase muscle mass. These agents are a recently recognized cause of hepatotoxicity and jaundice and may lead to acute kidney injury. To increase awareness about this growing problem and to characterize the pathology of acute kidney injury in this setting, we report on a young male who developed acute kidney injury in the setting of severe cholestatic jaundice related to ingestion of anabolic steroids used for bodybuilding. Kidney biopsy showed bile casts within distal tubular lumina, filamentous bile inclusions within tubular cells, and signs of acute tubular injury. This report supports the recently re-emerged concept of bile nephropathy cholemic nephrosis.

    To determine effects of the biochemical and cytological properties of blood, serum, and ascites on survival of patients with malignant peritoneal effusion (MPeE), including malignant peritoneal mesothelioma (MPeM) and peritoneal carcinomatosis (PC), we conducted a retrospective study of patients with MPeE and healthy controls. Potential prognostic factors were identified as follows: age, sex, blood neutrophil-to-lymphocyte ratio (NLR), serum parameters, ascites parameters, serum-ascites albumin gradient, and the ascites-serum LDH ratio. Compared to those of the control group, serum albumin levels were significantly lower, and the NLR and serum LDH levels were significantly higher in the MPeE group. Overall survival (OS) was longer in patients with MPeM compared to that in patients with PC. Compared with patients in the MPeM, patients with PC had higher NLRs, ascites glucose levels, serum-ascites albumin gradients, and serum LDH levels. In contrast, their ascites albumin levels and ascites-serum LDH ratios were lower. Univariate analyses indicated that the NLR, serum LDH levels, ascites LDH levels, ascites coenocyte levels, and the ascites coenocyte-to-monocyte ratios affected the OS. Multivariate analyses identified only serum and ascites LDH levels as independent prognostic factors.

  9. Stimulation of apical sodium-dependent bile acid transporter expands the bile acid pool and generates bile acids with positive feedback properties.

    Bile acid synthesis has been considered a prototype for how a physiological process is controlled by end product feedback inhibition. By this feedback inhibition, bile acid concentrations are kept within safe ranges. However, careful examination of published rodent data strongly suggests that bile acid synthesis is also under potent positive feedback control by hydrophilic bile acids. Current concepts on the regulation of bile acid synthesis are derived from mouse models. Recent data have shown that mice have farnesoid X receptor (FXR) antagonistic bile acids capable of quenching responses elicited by FXR agonistic bile acids. This is important to recognize to understand the regulation of bile acid synthesis in the mouse, and in particular to clarify if mouse model findings are valid also in the human situation. In addition to classic end product feedback inhibition, regulation of bile acid synthesis in the mouse largely appears also to be driven by changes in hepatic levels of murine bile acids such as α- and β-muricholic acids. This has not been previously recognized. Stimulated bile acid synthesis or induction of the apical sodium-dependent bile acid transporter in the intestine, increase the availability of chenodeoxycholic acid in the liver, thereby promoting hepatic conversion of this bile acid into muricholic acids. Recognition of these mechanisms is essential for understanding the regulation of bile acid synthesis in the mouse, and for our awareness of important species differences in the regulation of bile acid synthesis in mice and humans. 2015 S.

    The present study was aimed to examine the interaction of two bile salts viz. sodium cholate (NaC) and sodium deoxycholate (NaDC) with three ethylene polyoxide-polypropylene polyoxide (PEO-PPO-PEO) triblock copolymers with similar PPO but varying PEO micelles with a focus on the effect of pH on mixed micelles. Mixed micelles of moderately hydrophobic Pluronic ® P123 were examined in the presence of two bile salts and compared with those from very hydrophobic L121 and very hydrophilic F127. Both the bile salts increase the cloud point (CP) of copolymer solution and decreased apparent micelle hydrodynamic diameter (D h ). SANS study revealed that P123 forms small spherical micelles showing a decrease in size on progressive addition of bile salts. The negatively charged mixed micelles contained fewer P123 molecules but progressively rich in bile salt. NaDC being more hydrophobic displays more pronounced effect than NaC. Interestingly, NaC shows micellar growth in acidic media which has been attributed to the formation of bile acids by protonation of carboxylate ion and subsequent solubilization. In contrast, NaDC showed phase separation at higher concentration. Nuclear Overhauser effect spectroscopy (NOESY) experiments provided information on interaction and location of bile salts in micelles. Results are discussed in terms of hydrophobicity of bile salts and Pluronics ® and the site of bile salt in polymer micelles. Proposed molecular interactions are useful to understand more about bile salts which play important role in physiological processes. Copyright © 2018 Elsevier B.V. All rights reserved.

    During endoscopic examinations we collected fluid in the stomach that included reflux fluid from the duodenum, and assessed the effect of quantitatively determined bile acids on glandular atrophy and intestinal metaplasia using biopsy specimens. A total of 294 outpatients were enrolled in this study. Total bile acid concentration was measured by an enzyme immunoassay. Glandular atrophy and intestinal metaplasia scores were graded according to the Updated Sydney System. An effect of refluxed bile acids on atrophy and intestinal metaplasia was shown in the high-concentration reflux group in comparison with the control group. However, when the odds ratios (ORs) were calculated according to whether Helicobacter pylori (H. pylori) infection was present, no significant associations were shown between reflux bile acids and atrophy in either the H. pylori-positive cases or -negative cases. The same was true for intestinal metaplasia in the H. pylori-positive cases, whereas intestinal metaplasia was more pronounced in the high-concentration reflux group in the H. pylori-negative cases (OR 2.4, 95%CI 1.1-5.6). We could not clarify the effect of the reflux of bile acids into the stomach in the progression of atrophy. High-concentration bile acids had an effect on the progression of intestinal metaplasia in the H. pylori-negative cases.

    Full Text Available A female Labrador dog presented with a history of distended abdomen was subjected for clinical, physical, hemato-biochemical, eletrocardiographic, and ultrasonographic evaluations. Respiratory distress, weakness, fluid thrill on palpation of abdomen, cough, cyanotic tongue, and syncope were the significant manifestations. Elevated levels of creatine kinase, lactate dehydrogenase, alanine amino transferase, and alkaline phosphatase with normal blood urea nitrogen and creatinine were the common serum chemistry findings. Low voltage QRS complexes were the electrocardiographic abnormalities. Classical ground glass appearance of abdomen, and enlarged heart with increased sternal contact were the radiographic findings of abdomen and thorax. Ultrasonography of abdomen revealed floating viscera in the anechoic effusion with engorged and distended hepatic vasculature. 2-dimensional echocardiography revealed dilated right ventricle both on B- and M-mode. Further, insufficiency in mitral and tricuspid valves were recorded on pulsed and color flow Doppler. Hence, right heart failure due to ascites was confirmed, and the condition was successfully managed with losartas, spiranolactone, co-enzyme Q10 and tricholine citrate, and sorbitol.

    2014-01-01

    Full Text Available Bile duct adenomas are benign bile duct proliferations usually encountered as an incidental finding. Oncocytic bile duct neoplasms are rare and the majority are malignant. A 61-year-old male with a diagnosis of colorectal adenocarcinoma was undergoing surgery when a small white nodule was discovered on the surface of the right lobe of his liver. This lesion was composed of cytologically bland cells arranged in tightly packed glands. These cells were immunopositive for cytokeratin 7, negative for Hep Par 1, contained mucin, and had a Ki67 proliferation index of 8%. The morphology, immunophenotype, presence of mucin, and normal appearing bile ducts, as well as the increased Ki67 proliferation rate, were consistent with a bile duct adenoma with oxyphilic (oncocytic change. Oncocytic tumors in the liver are rare; the first described in 1992. Only two bile duct adenomas with oncocytic change have been reported and neither of them had reported mucin production or the presence of normal appearing bile ducts within the lesion.

    Three to 20 hr after an i.p. injection of 64 Cu (half-life, 12.8 hr) into mice bearing Krebs ascites cells, a high amount of the radioisotope was recovered in the ascites cells themselves. In the control group, the radioisotope was mainly present in the liver. Similar amounts of 64 Cu were recovered in regenerating as well as in normal liver, whereas in the liver of mice bearing ascites cells, this amount was lower by 40 to 50% regardless of the ascitic volume. Thus, the copper metabolism seems to be disturbed at the hepatic level in mice bearing ascites cells. The distribution of 64 Cu was 'analyzed in DNA, RNA, and proteins from cellular lysates fractionated by CsCl gradient. There was a uniform pattern of distribution in the macromolecules from ascites cells, while 64 Cu' was preferentially associated with the protein fraction from liver. Further experiments indicated that, in vivo, 64 Cu was bound to the DNA of ascites cells

    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.

    Full Text Available Abstract Background The purpose of this study was to determine risk factors for development of malignant ascites and its prognostic significance in patients with pancreatic cancer. Methods A prospective database was queried to identify patients with pancreatic cancer who develop ascites. Stage at presentation, size, and location of primary tumor, treatment received and length of survival after onset of ascites were determined. Results A total of 15 patients were identified. Of which 4 patients (1 stage II, 3 stage III underwent pancreaticoduodenectomy and manifested with ascites 2, 3, 24 and 47 months after surgery (tumor size 2.9 ± 1.32 cm. All but one of the remaining 11 patients (tumor size 4.4 ± 3.38 cm presented with metastatic disease, and all developed malignant ascites 9 months after diagnosis, dying 2 months later. Resected patients lived longer before the onset of ascites, but not after. Conclusion Once diagnosed, ascites in pancreatic cancer patients heralds imminent death. Limited survival should be considered when determining the aggressiveness of further intervention.

    Interactions between ovarian cancer cells and the surrounding tumor microenvironment are not well characterized. Here, we investigated the molecular mechanisms by which malignant ascites promote the metastasis of ovarian cancer. It was found that ovarian cancer ascites promoted ovarian cancer cell migration which was attenuated by either heat inactivation or antibody blockade of TGF-β. High level (at ng/ml level) of TGF-β was detected in the ascites. In addition, ascites repressed the expression of miRNA-125b in a TGF-β-dependent manner. Mimic of miR-125b blocked ascites-induced cell migration. Furthermore, Gab2 (a target gene of miR-125b) was elevated by ascites in a TGF-β-dependent manner. And forced expression of Gab2 reversed the inhibition of migration induced by miR-125b mimic. Most importantly, the expression of miR-125b and Gab2 mRNA was negatively correlated in ovarian cancer specimens. Taken together, our finding suggested that TGF-β in ascites promoted cancer cell migration through repression of miR-125b in ovarian cancer. This might provide a novel therapeutic target for ovarian cancer in the future.

    The rhythms of cell proliferation and DNA synthesis were studied in a hypotetraploid strain of Ehrlich's ascites tumor (EAT) and compared with data obtained previously on the hyperdiploid strain of EAT. Eighty-five noninbred male albino mice were used. An injection of tritium-thymidine, with specific radioactivity of 4.1 Ci/mmole, was given to the mice one hour before sacrifice. The results obtained are presented; it is shown that the number of DNA-synthesizing cells in the hypotetraploid strain during the 5th and 6th days of growth of EAT was 503 and 479 0 /00, respectively. Fluctuations of the radioactive index during these days were not significant. Only a significant fall in the radioactive index toward noon on the seventh day of development of the hypotetraploid strain of EAT was observed

    1983-12-01

    Selective peptide cleavage has provided a general procedure for the study of the structure, including stereochemistry, of plant bile pigments. The information derived from the synthesis and spectral analysis of a series of 2,3-dihydrodioxobilins allows the determination of the trans relative stereochemistry for ring A of the ..beta../sub 1/-phycocyanobilin from C-phycocyanin as well as for ring A of phytochrome. A complete structure proof of the five phycoerythrobilins attached to the ..cap alpha.. and ..beta.. subunits of B-phycoerythrin is described. One of these tetrapyrroles is doubly-peptide linked to a single peptide chain through two thioethers at the C-3' and C-18' positions. The four remaining phycoerythrobilins are singly-linked to the protein through thioethers at the C-3' position and all possess the probable stereochemistry C-2(R), C-3(R), C-3'(R), and C-16(R).

  2. L-lactate transport in Ehrlich ascites-tumour cells.

    Spencer, T L; Lehninger, A L

    1976-01-01

    Ehrlich ascites-tumour cells were investigated with regard to their stability to transport L-lactate by measuring either the distribution of [14C]lactate or concomitant H+ ion movements. The movement of lactate was dependent on the pH difference across the cell membrane and was electroneutral, as evidenced by an observed 1:1 antiport for OH- ions or 1:1 symport with H+ ions. 2. Kinetic experiments showed that lactate transport was saturable, with an apparent Km of approx. 4.68 mM and a Vmax. as high as 680 nmol/min per mg of protein at pH 6.2 and 37 degrees C. 3. Lactate transport exhibited a high temperature dependence (activation energy = 139 kJ/mol). 4. Lactate transport was inhibited competitively by (a) a variety of other substituted monocarboxylic acids (e.g. pyruvate, Ki = 6.3 mM), which were themselves transported, (b) the non-transportable analogues alpha-cyano-4-hydroxycinnamate (Ki = 0.5 mM), alpha-cyano-3-hydroxycinnamate (Ki = 2mM) and DL-p-hydroxyphenyl-lactate (Ki = 3.6 mM) and (c) the thiol-group reagent mersalyl (Ki = 125 muM). 5. Transport of simple monocarboxylic acids, including acetate and propionate, was insensitive to these inhibitors; they presumably cross the membrane by means of a different mechanism. 6. Experiments using saturating amounts of mersalyl as an "inhibitor stop" allowed measurements of the initial rates of net influx and of net efflux of [14C]lactate. Influx and efflux of lactate were judged to be symmetrical reactions in that they exhibited similar concentration dependence. 7. It is concluded that lactate transport in Ehrlich ascites-tumour cells is mediated by a carrier capable of transporting a number of other substituted monocarboxylic acids, but not unsubstituted short-chain aliphatic acids.

  3. Ascitic microbiota composition is correlated with clinical severity in cirrhosis with portal hypertension.

    Geraint B Rogers

    Full Text Available Identification of pathogenic bacteria in ascites correlates with poor clinical outcomes. Ascites samples are commonly reported culture-negative, even where frank infection is indicated. Culture-independent methods have previously reported bacterial DNA in ascites, however, whether this represents viable bacterial populations has not been determined. We report the first application of 16S rRNA gene pyrosequencing and quantitative PCR in conjunction with propidium monoazide sample treatment to characterise the viable bacterial composition of ascites. Twenty five cirrhotic patients undergoing paracentesis provided ascites. Samples were treated with propidium monoazide to exclude non-viable bacterial DNA. Total bacterial load was quantified by 16S rRNA Q-PCR with species identity and relative abundance determined by 16S rRNA gene pyrosequencing. Correlation of molecular microbiology data with clinical measures and diagnostic microbiology was performed. Viable bacterial signal was obtained in 84% of ascites samples, both by Q-PCR and pyrosequencing. Approximately 190,000 ribosomal pyrosequences were obtained, representing 236 species, including both gut and non gut-associated species. Substantial variation in the species detected was observed between patients. Statistically significant relationships were identified between the bacterial community similarity and clinical measures, including ascitic polymorphonuclear leukocyte count and Child-Pugh class. Viable bacteria are present in the ascites of a majority of patients with cirrhosis including those with no clinical signs of infection. Microbiota composition significantly correlates with clinical measures. Entry of bacteria into ascites is unlikely to be limited to translocation from the gut, raising fundamental questions about the processes that underlie the development of spontaneous bacterial peritonitis.

    Cancer is considered one of the most common causes of morbidity and mortality worldwide. Many researches have been studied on the discovery of natural and synthetic compounds that can be used in the prevention and/or treatment of cancer. Many chemo preventive agents have been associated with antiproliferative and apoptotic effects on cancer cells because of their high antioxidant activity. The present study was undertaken to investigate the antioxidant and antitumor effects of three natural extracts including (propolis, green tea and Chlorella vulgaris) without or with radiation exposure in Ehrlich ascites carcinoma (EAC) - bearing female albino mice. The animals were randomly distributed into three major groups as follows:- Group A (control group).This group consists of 10 mice kept on normal standard rodent diet without any treatment and housed in two cages: mice of the first cage served as control for non tumor-bearing group and the second cage served as control for tumor-bearing group. Group B (Non tumor - bearing group).This group consists of 30 mice and used to study the effect of the vehicle solutions (gum acacia, DMSO), propolis, green tea, Chlorella vulgaris and gamma irradiation on normal mice. Mice of this group were equally distributed into six subgroups receiving gum acacia, DMSO, propolis, green tea and Chlorella vulgaris for two weeks and whole body gamma irradiated. Group C (Tumor- bearing group): This group consists of 160 mice randomly and equally distributed into 8 subgroups: Ehrlich ascites carcinoma(mice were inoculated with 2.5 x 10 6 intra-peretoneally(i.p), Ehrlich ascites carcinoma and 2 Gy irradiated, Ehrlich ascites carcinoma and propolis treated (150 mg/kg b.w), Ehrlich ascites carcinoma, propolis treated and irradiated, Ehrlich ascites carcinoma and green tea treated (150 mg/kg b.w), Ehrlich ascites carcinoma, green tea treated and irradiated, Ehrlich ascites carcinoma and Chlorella vulgaris treated (150 mg/kg b.w) and Ehrlich ascites

    To describe a new intraoperative bile leakage test in patients undergoing a major liver resection aimed to combine the advantages of each of the other standard bile leakage tests (accurate visualization of leaks, reproducibility, and ease of use) without their disadvantages. At the end of the major hepatic resection, 10 to 30 mL of sterile fat emulsion, 5%, is injected via an olive-tip cannula through the cystic duct while manually occluding the distal common bile duct. As the biliary tree fills with fat emulsion solution, leakage of the white fluid is visualized on the raw surface of the liver resection margin. The detected leakages are closed by means of single stitches. Afterwards, the residual fat emulsion on the resection surface is washed off with saline and the White test is repeated to detect and/or exclude additional bile leakages. At the end, residual fat emulsion is washed out from the biliary tract by a low-pressure infusion of saline solution. Intraoperatively, additional potential bile leakages (not seen using a conventional saline bile leakage test) were identified in 74% of our patients. Postoperative bile leakages (within 30 days) occurred in only 5.1% of patients when the White test was used. No adverse effects related to this technique were observed. The White test has clear advantages in comparison with other bile leakage tests: it precisely detects bile leakages, regardless of size; it does not stain the resection surface, allowing it to be washed off and repeated ad infinitum; and it is safe, quick, and inexpensive.

    Malignant ascites (MA) is a common manifestation of advanced cancer. Currently, there are no evidence-based guidelines for the management of MA. We conducted a survey with physicians throughout Germany and Austria, to get an overview of current approaches and opinions in the treatment of MA. One hundred and twenty-eight medical oncologists (MO), gastroenterologists (GE), and gynecologists (GYN) completed an electronic questionnaire consisting of 33 questions. Ninety percent of the physicians were from Germany and 10% from Austria; 48% of those were MO, 30% were GYN, and 14% were GE. Most physicians treated an average of 34 patients (pts)/year with MA. Twenty-six percent of these pts suffered from ovarian, 20% from pancreatic, 17% from gastric, and 14% from colorectal cancer. The majority of the physicians associated MA with poor prognosis (92%) and significant reduction in quality of life (87%). One third felt that MA was a contraindication for full dosing of systemic chemotherapy. Paracentesis (PC) was performed in 70% of pts with symptom relieve and quality of life being the main reasons. Almost half of the pts required 3-5 PC, 50% even more than 5 PC during the course of their disease. Only 15% of pts needed multiple PC per week; the majority (79%) needed the procedure either once a week or every 14 days. In 61% of pts, 3-5 L of ascites fluid was drained. Only in 8%, 5 L and more were removed. Volume substitution with IV albumin was performed in 40% of pts. Most pts (55%) had to stay 1-3 h in a healthcare facility for the procedure. However, 21% had to stay ≥1 day. While almost all physicians (89%) performed a PC at some point in the treatment of MA, 75% felt that a systemic chemotherapy and 55% thought a concomitant diuretic therapy were a necessary adjunct. Seven percent of the pts received a targeted treatment with catumaxomab. Repeated PC is the main pillar of treatment of MA; its effect is only temporary and requires significant hospital resources

    [3beta-3H]-bile acids and bile alcohols may be useful for metabolic studies in man and animals because the 3-position is invulnerable to bacterial attack. A number of tritium labeled bile acids and bile alcohols were prepared by selective oxidation of the hydroxyl group at carbon-3 followed by reduction with NaBT4. In each case, the bile acids and bile alcohols epimeric at carbon-3 were resolved by analytical and preparative thin-layer chromatography and characterized by gas liquid chromatography. The average yield was 60 to 65% and specific activities of the final products were in the range of 7.4 x 10 7 dpm/mg

    The ratio of bile acids in the bile of rats with alloxan diabetes was investigated using the method of thin-layer chromatography. Changes of coefficients of conjugation and hydroxylation of bile acids were calculated and analyzed in half-hour samples of bile obtained during the 3-hour experiment. It has been found that the processes of conjugation of cholic acid with glycine and taurine are inhibited in alloxan diabetes. At the same time a significant increase of free threehydroxycholic and dixydroxycholic bile acids and conjugates of the latter ones with taurine has been registered. Coefficients of hydroxylation in alloxan diabetes show the domination of "acidic" pathway in bile acid biosynthesis that is tightly connected with the activity of mitochondrial enzymes.

    Multiple myeloma is a common hematological malignancy. Aggressive myeloma invades the organs outside the bone marrow, lymph, or reticuloendothelial systems. Among the extramedullary involvements of multiple myeloma, myelomatous ascites are extremely rare and are associated with a poor prognosis. We describe a case of myelomatous ascites as an initial manifestation of extramedullary involvement of multiple myeloma in 39-year-old patient. The patient was treated with high-dose chemotherapy, but extensive extramedullary involvement progressed, and the patient expired approximately five months after the initial detection of ascites.

    We report two cases of gastric varices complicated by massive ascites that disappeared after balloon-occluded retrograde transvenous obliteration (B-RTO). The first patient had progressive gastric varices that continued to enlarge even after three episodes of esophagogastric variceal bleeding, and the second patient was admitted to our hospital because of the bleeding from gastric varices. After B-RTO procedures in both patients, significant improvement of the ascites, hepatic function reserve, and hypoalbuminemia was observed. Although further experience is needed, our experience points to the likelihood of the amelioration of ascites after B-RTO

    This study was undertaken to gain insights into the characteristics of the polymolecular association between canalicular membrane enzymes, bile acids, cholesterol and phospholipids in bile and into the celular mechanisms whereby the enzymes are secreted into bile. With this purpose, we studied the distribution of bile acids, cholesterol, phospholipids, proteins and representative canalicular membrane enzymes (alkaline phosphatase, 5'-nucleotidase and gamma-glutamyl transpeptidase), which can be considered specific marker constituents, in bile fractions enriched in phospholipid-cholesterol lamellar structures (multilamellar and unilamellar vesicles) and bile acid-mixed micelles. These fractions were isolated by ultracentrifugation from human hepatic bile, normal rat bile and bile of rats treated with diosgenin, a steroid that induces a marked increase in biliary cholesterol secretion, and were characterized by density, lipid composition and transmission electron microscopy. These studies demonstrate that alkaline phosphatase, 5'-nucleotidase and gamma-glutamyl transpeptidase are secreted into both human and rat bile where they are preferentially associated with bile acid-mixed micelles, suggesting a role for bile acids in both release of these enzymes and lipids from the canalicular membrane and solubilization in bile. In addition, heterogeneous association of these enzymes with nonmicellar, lamellar structures in human and rat bile is consistent with the hypothesis that processes independent of the detergent effects of bile acids might also result in the release of specific intrinsic membrane proteins into bile.

  13. Allelic variation of bile salt hydrolase genes in Lactobacillus salivarius does not determine bile resistance levels.

    2009-09-01

    Commensal lactobacilli frequently produce bile salt hydrolase (Bsh) enzymes whose roles in intestinal survival are unclear. Twenty-six Lactobacillus salivarius strains from different sources all harbored a bsh1 allele on their respective megaplasmids. This allele was related to the plasmid-borne bsh1 gene of the probiotic strain UCC118. A second locus (bsh2) was found in the chromosomes of two strains that had higher bile resistance levels. Four Bsh1-encoding allele groups were identified, defined by truncations or deletions involving a conserved residue. In vitro analyses showed that this allelic variation was correlated with widely varying bile deconjugation phenotypes. Despite very low activity of the UCC118 Bsh1 enzyme, a mutant lacking this protein had significantly lower bile resistance, both in vitro and during intestinal transit in mice. However, the overall bile resistance phenotype of this and other strains was independent of the bsh1 allele type. Analysis of the L. salivarius transcriptome upon exposure to bile and cholate identified a multiplicity of stress response proteins and putative efflux proteins that appear to broadly compensate for, or mask, the effects of allelic variation of bsh genes. Bsh enzymes with different bile-degrading kinetics, though apparently not the primary determinants of bile resistance in L. salivarius, may have additional biological importance because of varying effects upon bile as a signaling molecule in the host.

    The purpose of this study was to determine the efficacy of CT to predict the development of bile leaks in hepatic trauma. This HIPAA-compliant retrospective study was IRB approved and consent was waived. All patients who sustained hepatic trauma between January 1, 2006, and January 31, 2012, and who underwent CT and hepatobiliary scans during the same hospital admission were included. One hundred and thirty-two patients met the inclusion criteria. Comparison between the presence of biliary injury relative to American Association for the Surgery of Trauma (AAST) hepatic injury grade and mean distance of the hepatic laceration to the inferior vena cava (IVC) was made. The ability of free fluid to predict bile injury was analyzed. Forty-one (31 %) of the 132 patients had positive hepatobiliary scans. Of these 41 patients, seven (17 %) sustained low-grade and 34 (83 %) sustained high-grade hepatic injury compared with the 37 (41 %) low-grade and 54 (59 %) high-grade hepatic injuries in the negative hepatobiliary scan group. The mean distance to the IVC was 2.4 cm (SD 2.9 cm) and 3.6 cm (SD 3.3 cm) in patients with and without bile leaks, respectively. A statistically significant difference in the proportion of high-grade injuries and the mean distance from the IVC between the two groups was identified. The presence of free fluid on CT is sensitive, but not specific, for detecting a bile leak. CT findings, including AAST liver injury grade and location of the liver laceration, are able to predict which patients are at risk for developing bile leaks as seen on hepatobiliary scintigraphy, whereas the presence of free fluid is not.

    1983-01-01

    Cholangiograms and clinical histories of 82 patients with biopsy-proved bile duct carcinoma were reviewed. The carcinomas were classified according to morphologic findings and clinical outcome. Ulcerative colitis and antecedent inflammatory disease of the biliary tree, particularly primary sclerosing cholangitis, seem to predispose to the development of bile duct carcinoma. Focal stenotic lesions were the most common morphologic type (62/82). Polypoid carcinomas and diffuse sclerosing carcinomas were less common and of about equal frequency. Prognosis was best for patients with polypoid carcinomas and worst for those with diffuse sclerosing carcinomas. In 69 cases (84%), the tumors involved the intrahepatic or proximal extrahepatic ducts, makin curative resection difficult or impossible. Patients with carcinomas limited to the more distal extrahepatic bile ducts had a longer average survival and a higher probability of surgical cure. Proper management of patients with bile duct carcinoma requires a complete and accurate cholangiographic evaluation of the morphology, location, and extent of the disease

    BACKGROUND Major bile duct injury is the most worrisome complication of cholecystectomy. There is no detailed data about the incidence or treatment-related costs of bile duct injuries in Turkey. We aimed to determine prevalence and therapeutic costs of patients with major biliary duct injuries managed in our department, and further estimate a projection of these parameters at the national level. MATERIAL AND METHODS All patients admitted due to bile duct injury during cholecystectomy from 2011 to 2014 were included. Healthcare costs were calculated by summing of their all treatment-related costs in Istanbul Medical Faculty. We collected 2014-2015 data on number of patients diagnosed with cholecystitis in Turkey, the number of cholecystectomies, and the number of the interventions performed following these initial surgeries, which were obtained from the Turkish Social Security Institution. RESULTS Forty-nine patients were enrolled and bilioenteric diversion was performed in 39 patients: 20.4% of patients had Bismuth II, 38.8% had Bismuth III, and 40.8% had Bismuth IV biliary stricture. Comparison of stricture types with total costs, days of hospitalization, and outpatient clinic costs revealed significant differences. Mean total cost of corrective surgeries was 9199 TRY. We estimated that 1.5% to 2.4% of patients who underwent cholecystectomy in Turkey have bile duct injury (including 0.3% with major bile duct injury). CONCLUSIONS New preventive strategies should be used to avoid bile duct injuries, which have a huge financial impact on the national economy.

    2013-03-01

    Full Text Available Ascites formation in patients with cirrhosis, portal hypertension, or both usually results from hyperdynamic circulatory dysfunction, where the retention of sodium and water is associated with the activation of the sympathetic and renin–angiotensin–aldosterone systems. The presence of ascites indicates the development of liver decompensation. Furthermore, complications seen in conjunction with ascites such as spontaneous bacterial peritonitis, hepatorenal syndrome, and hepatic hydrothorax may result in increased morbidity and mortality. Although nonpharmacological, pharmacological, and surgical approaches have been introduced and clinically practiced, their therapeutic effects are still suboptimal or limited by their potential side effects, such as large-volume paracentesis-induced postparacentesis circulatory dysfunction. Herein, we discuss strategies to prevent and properly manage ascites-related complications, including a review of the literature and controlled studies that assess these strategies.

    Liver transplantation preserving the retrohepatic interior vena cava, the so-called piggyback technique, is becoming more frequently used because it avoids caval cross-clamping during the anhepatic phase of surgery. However, hepatic venous outflow blockade causing ascites seems to be less infrequent after piggyback than with cavo-caval anastomosis. We report a 62-year-old patient who underwent liver transplantation using the piggyback technique and developed a stenosis in the anastomosis between the hepatic veins and the inferior vena cava leading to severe postoperative ascites. Ascites was unresponsive to diuretic therapy and was associated with renal function impairment. Since the etiology of the stenosis was mechanical (torsion), percutaneous transluminal angioplasty was unsuccessful. Finally, an autoexpandable prosthesis was placed across the anastomosis resulting in rapid and permanent (3 years of follow-up) resolution of ascites.

    The pathogenesis of nonanastomotic strictures with a patent hepatic artery remains to be investigated. This study focuses on the role of cholangiocyte bile acid transporters in bile duct injury after liver transplantation. Sprague-Dawley rats were divided into three groups (n=20 for each): the sham-operated group (Sham), the transplant group with 1-hr donor liver cold preservation (CP-1h), and the transplant group with 12-hr donor liver cold preservation (CP-12h). Bile was collected for biochemical analysis. The histopathologic evaluation of bile duct injury was performed and the cholangiocyte bile acid transporters apical sodium-dependent bile acid transporter (ASBT), ileal lipid binding protein (ILBP), and Ostalpha/Ostbeta were investigated. RESULTS.: The immunohistochemical assay suggested that ASBT and ILBP were expressed exclusively on large bile duct epithelial cells, whereas Ostalpha and Ostbeta were expressed on both small and large bile ducts. Western blot and quantitative polymerase chain reaction analysis showed that the expression levels of these transporters dramatically decreased after transplantation. It took seven to 14 days for ILBP, Ostalpha, and Ostbeta to recover, whereas ASBT recovered within 3 days and even reached a peak above the normal level seven days after operation. In the CP-12h group, the ratios of the ASBT/ILBP, ASBT/Ostalpha and ASBT/Ostbeta expression levels were correlated with the injury severity scores of large but not small bile ducts. The results suggest that the unparallel alteration of cholangiocyte bile acid transporters may play a potential role in large bile duct injury after liver transplantation with prolonged donor liver preservation.

    Full Text Available Obesity, diabetes, and metabolic syndromes are increasingly recognized as health concerns worldwide. Overnutrition and insulin resistance are the major causes of diabetic hyperglycemia and hyperlipidemia in humans. Studies in the past decade provide evidence that bile acids are not just biological detergents facilitating gut nutrient absorption, but also important metabolic regulators of glucose and lipid homeostasis. Pharmacological alteration of bile acid metabolism or bile acid signaling pathways such as using bile acid receptor agonists or bile acid binding resins may be a promising therapeutic strategy for the treatment of obesity and diabetes. On the other hand, bile acid signaling is complex, and the molecular mechanisms mediating the bile acid effects are still not completely understood. This paper will summarize recent advances in our understanding of bile acid signaling in regulation of glucose and lipid metabolism, and the potentials of developing novel therapeutic strategies that target bile acid metabolism for the treatment of metabolic disorders.

    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.

    Changes of bile salt tolerance, morphology and amount of bile acid within cells were studied to evaluate the exact effects of bile salt hydrolase (BSH) on bile salt tolerance of microorganism. The effect of BSHs on the bile salt tolerance of Lactococcus lactis was examined by expressing two BSHs (BSH1 and BSH2). Growth of L. lactis expressing BSH1 or BSH2 was better under bile salt stress compared to wild-type L. lactis. As indicated by transmission electron microscopy, bile acids released by the action of BSH induced the formation of micelles around the membrane surface of cells subject to conjugated bile salt stress. A similar micelle containing bile acid was observed in the cytoplasm by liquid chromatography-mass spectrometry. BSH1 produced fewer bile acid micelles in the cytoplasm and achieved better cell growth of L. lactis compared to BSH2. Expression of BSH improved bile salt tolerance of L. lactis but excessive production by BSH of bile acid micelles in the cytoplasm inhibited cell growth.

  10. Role of the Intestinal Bile Acid Transporters in Bile Acid and Drug Disposition

    Dawson, Paul A.

    2011-01-01

    Membrane transporters expressed by the hepatocyte and enterocyte play critical roles in maintaining the enterohepatic circulation of bile acids, an effective recycling and conservation mechanism that largely restricts these potentially cytotoxic detergents to the intestinal and hepatobiliary compartments. In doing so, the hepatic and enterocyte transport systems ensure a continuous supply of bile acids to be used repeatedly during the digestion of multiple meals throughout the day. Absorption of bile acids from the intestinal lumen and export into the portal circulation is mediated by a series of transporters expressed on the enterocyte apical and basolateral membranes. The ileal apical sodium-dependent bile acid cotransporter (abbreviated ASBT; gene symbol, SLC10A2) is responsible for the initial uptake of bile acids across the enterocyte brush border membrane. The bile acids are then efficiently shuttled across the cell and exported across the basolateral membrane by the heteromeric Organic Solute Transporter, OSTα-OSTβ. This chapter briefly reviews the tissue expression, physiology, genetics, pathophysiology, and transport properties of the ASBT and OSTα-OSTα. In addition, the chapter discusses the relationship between the intestinal bile acid transporters and drug metabolism, including development of ASBT inhibitors as novel hypocholesterolemic or hepatoprotective agents, prodrug targeting of the ASBT to increase oral bioavailability, and involvement of the intestinal bile acid transporters in drug absorption and drug-drug interactions.

    Bile possesses antibacterial activity because bile salts disrupt membranes, denature proteins, and damage DNA. This study describes mechanisms employed by the bacterium Salmonella enterica to survive bile. Sublethal concentrations of the bile salt sodium deoxycholate (DOC) adapt Salmonella to survive lethal concentrations of bile. Adaptation seems to be associated to multiple changes in gene expression, which include upregulation of the RpoS-dependent general stress response and other stress responses. The crucial role of the general stress response in adaptation to bile is supported by the observation that RpoS− mutants are bile-sensitive. While adaptation to bile involves a response by the bacterial population, individual cells can become bile-resistant without adaptation: plating of a non-adapted S. enterica culture on medium containing a lethal concentration of bile yields bile-resistant colonies at frequencies between 10−6 and 10−7 per cell and generation. Fluctuation analysis indicates that such colonies derive from bile-resistant cells present in the previous culture. A fraction of such isolates are stable, indicating that bile resistance can be acquired by mutation. Full genome sequencing of bile-resistant mutants shows that alteration of the lipopolysaccharide transport machinery is a frequent cause of mutational bile resistance. However, selection on lethal concentrations of bile also provides bile-resistant isolates that are not mutants. We propose that such isolates derive from rare cells whose physiological state permitted survival upon encountering bile. This view is supported by single cell analysis of gene expression using a microscope fluidic system: batch cultures of Salmonella contain cells that activate stress response genes in the absence of DOC. This phenomenon underscores the existence of phenotypic heterogeneity in clonal populations of bacteria and may illustrate the adaptive value of gene expression fluctuations. PMID:22275872

    Up to now the diagnosis of early stage cholangiocarcinoma (CC) has remained difficult, with low sensitivities reported for current diagnostic methods. Based on recent promising findings about circulating U2 small nuclear RNA fragments (RNU2-1f) as novel blood-based biomarkers for pancreatic and colorectal adenocarcinoma, we studied the utility of RNU2-1f as a diagnostic marker of CC in bile fluid. Bile fluid was collected from patients with CC (n = 12), controls (patients with choledocholithiasis) (n = 11) and with primary sclerosing cholangitis (PSC; n = 11). RNU2-1f levels were measured by real-time polymerase chain reaction normalized to cel-54. Measurement of RNU2-1f levels in bile fluids enabled the differentiation of patients with CC from controls in all cases. Furthermore, RNU2-1f levels in bile fluids of patients with CC were significantly higher than in patients with PSC, resulting in a receiver-operating characteristic curve area of 0.856, with sensitivity of 67 % and specificity of 91 %. Our data suggest that the measurement of RNU2-1 fragments detected in the bile fluid can be used as a diagnostic marker for CC and should be included in future prospective diagnostic studies for this disease entity.

    Normal mice immunised with irradiated Ehrlich ascites tumor (EAT) cells rejected EAT challenge given 2 weeks later but T-cell-deficient thymectomised lethally irradiated, and bone-marrow-reconstituted (TIR) mice succumbed. However, when TIR mice were injected i.v. with thymus, lymph node, or spleen cells from normalsyngetic donors immediately following i.p. injection of irradiated EAT cells, they rejected the subsequent tumor challenge. This induction of immunity in TIR mice was shown to be T-cell dependent. Spleen cells from EAT- bearing mice given immediately after irradiated tumor cells were also able to promote rejection of EAT challenge in TIR mice. Spleen cells from EAT-immune mice inhibited EAT growth when admixed with tumor cells prior to i.p. injection into normal recipients, but had no effect on progressive tumor growth when given i.v. immediately after i.p. tumor injection. Immune serum inhibited i.p. EAT growth when given either i.p. or i.v. Whereas inhibition of EAT growth by admixed spleen cells was shown to be T-cell independent. The data indicate that T lymphocytes are required only in the induction phase of the immune reponse of mice against EAT, while the efferent phase of the response is accomplished by serum antibodies, perhaps through an interaction with host macrophages.

    Ehrlich ascites-tumour cells accumulate Ca2+ when incubated aerobically with succinate, phosphate and rotenone, as revealed by isotopic and atomic-absorption measurements. Ca2+ does not stimulate oxygen consumption by carefully prepared Ehrlich cells, but des so when the cells are placed in a hypo-osmotic medium. Neither glutamate nor malate support Ca2+ uptake in 'intact' Ehrlich cells, nor does the endogenous NAD-linked respiration. Ca2+ uptake is completely dependent on mitochondrial energy-coupling mechansims. It was an unexpected finding that maximal Ca2+ uptake supported by succinate requires rotenone, which blocks oxidation of enogenous NAD-linked substrates. Phosphate functions as co-anion for entry of Ca2+. Ca2+ uptake is also supported by extra-cellular ATP; no other nucleoside 5'-di- or tri-phosphate was active. The accumulation of Ca2+ apparently takes place in the mitochondria, since oligomycin and atractyloside inhibit ATP-supported Ca2+ uptake. Glycolysis does not support Ca2+ uptake. Neither free mitochondria released from disrupted cells nor permeability-damaged cells capable of absorbing Trypan Blue were responsible for any large fraction of the total observed energy-coupled Ca2+ uptake. The observations reported also indicate that electron flow through energy-conserving site 1 promotes Ca2+ release from Ehrlich cells and that extra-cellular ATP increase permeability of the cell membrane, allowing both ATP and Ca2+ to enter the cells more readily.

  17. Bile acid metabolism and signaling in cholestasis, inflammation and cancer

    Science.gov (United States)

    2015-01-01

    Bile acids are synthesized from cholesterol in the liver. Some cytochrome P450 (CYP) enzymes play key roles in bile acid synthesis. Bile acids are physiological detergent molecules, so are highly cytotoxic. They undergo enterohepatic circulation and play important roles in generating bile flow and facilitating biliary secretion of endogenous metabolites and xenobiotics and intestinal absorption of dietary fats and lipid soluble vitamins. Bile acid synthesis, transport and pool size are therefore tightly regulated under physiological conditions. In cholestasis, impaired bile flow leads to accumulation of bile acids in the liver, causing hepatocyte and biliary injury and inflammation. Chronic cholestasis is associated with fibrosis, cirrhosis and eventually liver failure. Chronic cholestasis also increases the risk of developing hepatocellular or cholangiocellular carcinomas. Extensive research in the last two decades has shown that bile acids act as signaling molecules that regulate various cellular processes. The bile acid-activated nuclear receptors are ligand-activated transcriptional factors that play critical roles in the regulation of bile acid, drug and xenobiotic metabolism. In cholestasis, these bile acid-activated receptors regulate a network of genes involved in bile acid synthesis, conjugation, transport and metabolism to alleviate bile acid-induced inflammation and injury. Additionally, bile acids are known to regulate cell growth and proliferation, and altered bile acid levels in diseased conditions have been implicated in liver injury/regeneration and tumorigenesis. We will cover the mechanisms that regulate bile acid homeostasis and detoxification during cholestasis, and the roles of bile acids in the initiation and regulation of hepatic inflammation, regeneration and carcinogenesis.

    In order to investigate the relationship between the excretion of Am-241 in bile and in feces, two young adult female baboons underwent cholecystopexy surgery to facilitate gallbladder bile sampling by needle puncture through the abdominal wall. Am-241 was injected intravenously in citrate form at dose levels of 0.090 and 0.098 μCi/kg. It has been observed that concentrations of Am-241 in bile increase gradually at early times post injection, reach a peak at 3 to 5 weeks and then decrease slowly over a period of several months, similar to the pattern of Am-241 excretion in feces. At times greater than one week post Am-241 injection, there is a 1 : 1 correlation between the activity measured in bile and that which appears in the feces a few days later, indicating that Am-241 excreted in feces represents elimination primarily from liver and that significant reabsorption by the intestines does not occur as is true for other bile constituents. At earlier times, less than one week post injection, Am-241 appears in feces via other pathways in addition to the biliary route

    In 50 blood donors, 87 patients with various liver and bile disorders, 50 hemodialyse patients and 50 patients prior to and immediately after cardiac swigery, cholyl glycine (CG) and sulfolithocholyl glycine (SLCG) were determined. Long-term observations were carried out on a further 10 patients with non-A/non-B hepatitis and 10 patients without hepatitis. Correlations were found between the values of alkaline phosphatase, GPT, GOT and bilirubin. Consequently the determination of bile acid, here above all SLCG, constitutes a suitable means to detect subclinical functional liver disorders. The examination of the post-operative functional liver disorders following cardiac swigery showed that there is a distinct time shift between the mostly transitory increase in enzyme activity and the SLCG levels. Surprisingly, the long-term observations showed that increased bile acid levels are already measured during the hepatitis incubation period at normal enzyme activities. It was not possible, however to identify hepatitic patients already during incubation by assay of the bile acid level. Whereas the determination of standard laboratory parameters remains predominant in the description of liver cell damage, the importance of serum bile acid determination is seen in the description of functional liver disorders which are not characterized by increased enzyme activities.

    Bile acids are regulators of lipid and glucose metabolism, and modulate inflammation in the liver and other tissues. Primary bile acids such as cholic acid and chenodeoxycholic acid (CDCA) are produced in the liver, and converted into secondary bile acids such as deoxycholic acid (DCA) and lithocholic acid by gut microbiota. Here we investigated the possible roles of bile acids in non-alcoholic fatty liver disease (NAFLD) pathogenesis and the impact of the gut microbiome on bile acid signalling in NAFLD. Serum bile acid levels and fibroblast growth factor 19 (FGF19), liver gene expression profiles and gut microbiome compositions were determined in patients with NAFLD, high-fat diet-fed rats and their controls. Serum concentrations of primary and secondary bile acids were increased in patients with NAFLD. In per cent, the farnesoid X receptor (FXR) antagonistic DCA was increased, while the agonistic CDCA was decreased in NAFLD. Increased mRNA expression for cytochrome P450 7A1, Na + -taurocholate cotransporting polypeptide and paraoxonase 1, no change in mRNA expression for small heterodimer partner and bile salt export pump, and reduced serum FGF19 were evidence of impaired FXR and fibroblast growth factor receptor 4 (FGFR4)-mediated signalling in NAFLD. Taurine and glycine metabolising bacteria were increased in the gut of patients with NAFLD, reflecting increased secondary bile acid production. Similar changes in liver gene expression and the gut microbiome were observed in high-fat diet-fed rats. The serum bile acid profile, the hepatic gene expression pattern and the gut microbiome composition consistently support an elevated bile acid production in NAFLD. The increased proportion of FXR antagonistic bile acid explains, at least in part, the suppression of hepatic FXR-mediated and FGFR4-mediated signalling. Our study suggests that future NAFLD intervention may target the components of FXR signalling, including the bile acid converting gut microbiome. © Article

    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.

    Full Text Available Objective: The aim of the study was to present a case series of the sparsely reported complication of chylous ascites (CA after left sided robot-assisted laparoscopic partial nephrectomy (RALPN, identify possible risk factors for the development of postoperative CA, and explore current recommendations for identification, management and prevention of CA. Material and methods: A retrospective review of patients that were treated with a RALPN during a one year time period (August 2012 to August 2013 by one surgeon at our institution was conducted. A total of 12 patients were included in the study. Demographics, tumor characteristics, and perioperative outcomes were assessed. Results: Three patients in the study experienced postoperative CA. All three patients had left sided surgery. The initial clinical suspicion for CA was raised due to complaints of abdominal pain with increased milky appearance of JP fluid. JP triglycerides were elevated in all three patients. The patients responded to conservative measures, with two patients treated with medium chain triglyceride diets and one patient treated with total parenteral nutrition (TPN. Among the patients treated with RALPN, the group that was diagnosed with postoperative CA (CA group was found to have a statistically significant lower average body mass index (BMI as compared to the group that did not have CA (non-CA group (24.67 kg/m2 in the CA group versus 31.77 kg/m2 in the non-CA group; P = 0.026. Other demographic data, tumor characteristics, and perioperative outcomes were similar in both groups. Conclusions: CA as a result of RALPN is a newly reported and rare postoperative complication. As utilization of RALPN continues to increase, urologists should be aware of this possible complication and be adept at diagnosing and managing CA. We suggest that left sided retroperitoneal surgery and a lower BMI preoperatively be considered risk factors for developing this complication.

    Malignant ascites (MA) is the abnormal accumulation of fluid in the peritoneal cavity of patients with intraperitoneal dissemination of their disease and is associated with a short life expectancy. The most common clinical feature is a progressive increase of abdominal distention resulting in pain, discomfort, anorexia and dyspnoea. Currently, no treatment is established standard of care due to limited efficacy or considerable toxicity. The objective was to examine the efficacy of laparoscopic hyperthermic intraperitoneal chemotherapy (HIPEC) in the palliation of refractory MA in patients who were unsuitable for cytoreductive surgery. From May 2009 to June 2015, 12 patients with MA due to their peritoneal malignancy were treated with laparoscopic HIPEC. The time between operation and repeat paracentesis, in-hospital data, and the proportion of patients that did not require repeat paracentesis was analyzed. One patient (8%) was admitted to ICU for 1 day. The mean operating time and hospital stay was 149.3 min (range 79-185) and 4.6 days (range 2-11) respectively. Neither high-grade morbidity nor mortality was observed. The median OS was 57 days. In our experience, a complete and definitive disappearance of MA was observed in 83% of patients. Two patients (17%) developed recurrent MA 124 days and 283 days post-HIPEC. Laparoscopic HIPEC is a beneficial treatment for the management and palliation of refractory MA and results in an excellent clinical and radiological resolution in patients with a complete resolution observed in selected patients.

  5. Speed of change in biliary lipids and bile acids with chenodeoxycholic acid--is intermittent therapy feasible?

    To see whehter intermittent chenodeoxycholic acid (CDCA) therapy is a potential alternative to continous treatment for gallstone dissolution, the speed of change in bile lipid composition was studied after starting and stopping CDCA therapy. In addition, the relationship between bile lipid composition and the proportions of the bile acids was examined. Bile-rich duodenal fluid was collected twice in the first week and then at approximately weekly intervals for four to six weeks, from six gallstone patients starting 13-15 mg CDCA.kg BW-1 day-1 and from another group of six patients whose treatment was stopped after gallstone dissolution. After starting treatment, the mean biliary cholesterol saturation index (based on criteria of Hegardt and Dam, 1971) decreased from 1-49 +/- SEM 0-17 to 0-92 +/- 0-13 at three weeks and 0-88 +/- 0-10 at four weeks, by which time bile lipid composition had become relatively constant. In patients whose treatment was stopped, bile reverted to its supersaturated state within one week, changing from an on-treatment mean saturation index of 0-74 +/- 0-10 to 1-15 +/- 0-15 in six to eight days after withdrawing CDCA. The proportion of conjugated CDCA in the biliary bile acids increased from 27-9 +/- 2-5% to 60-5 +/- 4-2% within four days and to 80-7 +/- 6-2% by four weeks after starting CDCA. When treatment was stopped, the proportion of CDCA reverted to pretreatment levels by two to three weeks. The saturation index was significantly related (P less than 0-001) to the percent of conjugated CDCA present, such that when the proportion of CDCA exceeded 70%, bile was almost invariably unsaturated. Since the mean time taken for bile to become unsaturated was not shorter than the time taken for bile to revert to its supersaturated state, it seems that intermittent treatment would not be adequate to maintain an unsaturated bile and is, therefore, unlikely to be as effective as continuous treatment in dissolving gallstones.

    ABSTRACT Emerging evidence strongly suggest that the human “microbiome” plays an important role in both health and disease. Bile acids function both as detergents molecules promoting nutrient absorption in the intestines and as hormones regulating nutrient metabolism. Bile acids regulate metabolism via activation of specific nuclear receptors (NR) and G-protein coupled receptors (GPCRs). The circulating bile acid pool composition consists of primary bile acids produced from cholesterol in the liver, and secondary bile acids formed by specific gut bacteria. The various biotransformation of bile acids carried out by gut bacteria appear to regulate the structure of the gut microbiome and host physiology. Increased levels of secondary bile acids are associated with specific diseases of the GI system. Elucidating methods to control the gut microbiome and bile acid pool composition in humans may lead to a reduction in some of the major diseases of the liver, gall bladder and colon. PMID:26939849

    Algorithms for diagnosis of malignant common bile duct (CBD) stenoses are complex and lack accuracy. Malignant tumors secrete large numbers of extracellular vesicles (EVs) into surrounding fluids; EVs might therefore serve as biomarkers for diagnosis. We investigated whether concentrations of EVs in bile could discriminate malignant from nonmalignant CBD stenoses. We collected bile and blood samples from 50 patients undergoing therapeutic endoscopic retrograde cholangiopancreatography at university hospitals in Europe for CBD stenosis of malignant (pancreatic cancer, n = 20 or cholangiocarcinoma, n = 5) or nonmalignant (chronic pancreatitis [CP], n = 15) origin. Ten patients with CBD obstruction due to biliary stones were included as controls. EV concentrations in samples were determined by nanoparticle tracking analyses. The discovery cohort comprised the first 10 patients with a diagnosis of pancreatic cancer, based on tissue analysis, and 10 consecutive controls. Using samples from these subjects, we identified a threshold concentration of bile EVs that could best discriminate between patients with pancreatic cancer from controls. We verified the diagnostic performance of bile EV concentration by analyzing samples from the 30 consecutive patients with a diagnosis of malignant (pancreatic cancer or cholangiocarcinoma, n = 15) or nonmalignant (CP, n = 15) CBD stenosis. Samples were compared using the Mann-Whitney test and nonparametric Spearman correlation analysis. Receiver operating characteristic area under the curve was used to determine diagnostic accuracy. In both cohorts, the median concentration of EVs was significantly higher in bile samples from patients with malignant CBD stenoses than controls or nonmalignant CBD stenoses (2.41 × 10 15 vs 1.60 × 10 14 nanoparticles/L in the discovery cohort; P bile best distinguished patients with malignant CBD from controls in the discovery cohort.

    The formation of supramolecular complexes between bilirubin and primary micelles of bile salts has been studied. The association constants of bile salts and binding of bilirubin with these associates have been determined. The adsorption of bilirubin and bile salts from individual and mixed aqueous solutions onto hydrophobic silica surfaces has been investigated. The interaction of bilirubin with primary bile salt micelles and the strong retention in mixed micelles, which are supramolecular complexes, result in the adsorption of bilirubin in free state only.

    1983-01-01

    Exponentially growing and plateau-phase cultures of Ehrlich ascites tumor cells were irradiated with heavy ions (Z greater than or equal to 20) and assayed for loss of reproductive capacity either immediately or at delayed times after irradiation. The results indicated no modification of the exponential dose response due to conditions which usually favor the repair of potentially lethal damage at low ionization density. Postirradiation treatment of the cells with a DNA synthesis inhibitor known to act on PLD repair resulted in effects similar to those observed without this drug and confirmed the hypothesis that at such high values of ionization density only lethal, unmodifiable damage can be expressed. The inactivation cross-section values calculated from the slope of the measured survival curves showed no significant correlations with commonly used parameters of radiation quality. Instead, a functional dependence on the primary ion energy was indicated, being smaller by a factor of two at low energies (less than or equal to 2 MeV/amu) compared with values at energies above 4 MeV/amu, where agreement with the morphological nuclear cross section of the culture was found. This suggests that at higher specific ion energies energetic secondary electrons contribute to the induction of lethal damage, and that interaction of damaged sites between the primary track and the track ends of delta electrons may occur. The data are therefore also discussed in terms of the penumbra model which emphasizes the role of delta electrons in cell killing when radiations with very high ionization density are applied

    We investigated the dependence of the cellular uptake of 57 cobalt-bleomycin on the exposure time and on the dose. In addition we observed the influences due to the incubation temperature, to the growth phase of the tumor cells and due to the composition of the suspensory medium. In supplementary experiments we investigated the binding of the labelled cytostatic agent to erythrocytes, its adsorption to broken Ehrlich ascites tumor cells and the 57 cobalt-bleomycin outflow from pre-loaded intact Ehrlich ascites tumor cells. The 57 cobalt-bleomycin uptake of intact Ehrlich ascites tumor cells is determined by characteristic kinetics. Moreover, the erythrocytes and injured Ehrlich ascites tumor cells show a qualitatively similar graph of the 57 cobalt-bleomycin binding, which can clearly be distinguished from the kinetics found with intact Ehrlich ascites tumor cells. The uptake of this cytostatic agent depends on an unequivocal time-dose-temperature relationship. The transport mechanism of the 57 cobalt-bleomycin uptake was considered as endocytosis. An endocytosis-stimulating inducer could not be detected. However, we obtained indications that the cell-bound cytostatic agent is taken up in two compartments: on the cellular surface and in the interior of the cell. (orig./MG) [de

    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 IGF-I receptor (IGF-IR) in vitro (+31%, P IGF-I, and lower levels of IGF-II (P 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 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

    Blunt trauma is an unusual cause of extrahepatic bile duct injury. This is a case of a 51-year-old gentleman who sustained a significant seatbelt injury in a plane crash. Laparotomy, performed due to persistent abdominal pain, revealed that the common bile duct (CBD) was completely avulsed from the duodenum. Following insertion of drains and transfer to a hepatobiliary centre, the devascularised CBD was excised and replaced with a roux-en-y hepaticojejunostomy. Necrotic tissue was debrided from the pancreatic head. A persistent bile leak developed from the sub-hepatic drain. Repeat laparotomy revealed a bile leak from small ducts on the liver surface. Ligation of the ducts and bioglue sealing of the area were successfully performed. Subsequent to this a pancreatic fistula developed from the main pancreatic duct, which has since resolved. This unusual case illustrates the need for prompt recognition and early repair to optimise outcomes in traumatic CBD injury.

    A method for the simultaneous determination of eight kinds of conjunct bile acids in human bile was developed by HPLC. They were separated on a YWG-C18 (3 microns) column at 30 degrees C, with methanol/water (65/35, V/V, pH3.0) as mobile phase, and detection wavelength at UV 210 nm. The linear ranges were 50-1,000 microns.ml-1, the recoveries were 91.2%-108.6%. The biles of 30 cases with cholelithiasis cholecystolithiasis and 20 cases without gallstone were detected by HPLC. The results showed that the constitution of bile acids was different between patients with cholelithiasis cholecystolithiasis and patients without gallstone.

    By December 1998, 24 patients with non-resected hilar bile duct cancer (mean age of 74) had received bile duct intracavitary irradiation and 13 patients with residual cancer after resection of hilar bile duct cancer had received postoperative intracavitary irradiation. After they were externally irradiated 30 Gy in total by 15 fractions (2 Gy/time, 5 times in a week), intracavitary irradiation using 192-Ir was given 5 times in total (2 times in a week) from 3 weeks after external irradiation under the condition which dose became 8 Gy in depth of 10 mm from radiation source. The cases of postoperative irradiation had 3 times in total. As for 20 patients of non-resected hilar bile duct cancer without metastasis, 50% survival time was 265 days and there was no 5 year survivor. Fifty percents survival time of 4 patients with metastasis was 113 days. The effect of local control was recognized in 20 patients (83.3%). In 13 patients of postoperative irradiation, 50% survival time was 554 days, and survival rate of 3 years was 28%. (K.H.)

    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 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.

    To assess how ascites and alpha-fetoprotein (AFP) added to the Barcelona Clinic Liver Cancer (BCLC) staging predict hepatocellular carcinoma survival. 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. 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, patients with AFP ≥ 200

    We evaluated the preoperative CT findings in 10 patients with colon carcinoma in whom peritoneal metastases had been surgically confirmed. Seven patients lacked ascites. No CT findings suggestive of peritoneal metastasis were observed in two patients without ascites even by retrospective evaluation. A large mass was observed in the cul-de-sac in another. In the remaining four patients, small peritoneal metastases ranging from 8 to 11 mm in diameter were observed at the omentum in two, along the falciform ligament in one, and at both the omentum and the iliac fossa in one; three of these patients had received no prospective diagnosis of peritoneal metastasis prior to the surgery. In patients with advanced colon carcinoma with suspected serosal invasion, the entire peritoneal cavity should be carefully examined and interpreted using CT in order to detect small peritoneal implants even when ascites is absent.

    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.

    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- 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 expenditures.

    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.

    Background/Aims Endoscopic retrograde cholangiopancreatography (ERCP) can be an effective treatment for bile leakage after liver transplantation. We evaluated the efficacy of endoscopic treatment in liver transplantation in patients who developed bile leaks. Methods Forty-two patients who developed bile leaks after liver transplantation were included in the study. If a bile leak was observed on ERCP, a sphincterotomy was performed, and a nasobiliary catheter was then inserted. If a bile leak was accompanied by a bile duct stricture, either the stricture was dilated with balloons, followed by nasobiliary catheter insertion across the bile duct stricture, or endoscopic retrograde biliary drainage was performed. Results In the bile leakage alone group (22 patients), endoscopic treatment was technically successful in 19 (86.4%) and clinically successful in 17 (77.3%) cases. Among the 20 patients with bile leaks with bile duct strictures, endoscopic treatment was technically successful in 13 (65.0%) and clinically successful in 10 (50.0%) cases. Among the 42 patients who underwent ERCP, technical success was achieved in 32 (76.2%) cases and clinical success was achieved in 27 (64.3%) cases. Conclusions ERCP is an effective and safe therapeutic modality for bile leaks after liver transplantation. ERCP should be considered as an initial therapeutic modality in post-liver transplantation patients. PMID:25717048

    Objective: To evaluate CT features of intrahepatic bile duct abscess (IBDA) and its pathologic basis. Methods: The CT imaging data of 31 consecutive cases of intrahepatic bile duct abscess proved by surgery or clinical treatments from October 1989 to February 1999 were retrospectively studied. The causes included acute obstructive suppurative cholangitis and retrograde infection due to different etiologies. For all the cases, the CT manifestations of liver abscess, bile duct abnormalities, and their relationship were observed respectively. Results: Manifestations of liver abscess were revealed in all cases (31/31, 100%). The CT manifestations of bile duct abnormalities included signs of etiologies caused bile duct obstruction and other signs including cholangiectasis (29/31, 93.5%), the dilated bile ducts communicated with (5/31, 16.1%) or abut on (8/31, 25.8%) the abscesses, and gas collection in bile ducts (10/31, 32.2%). The signs showing the relationship between liver abscess and bile duct abnormalities were that the abscesses complied with the obstructive site and the dilated bile ducts (15/31, 48.4%), and the liver abscesses located in different (7/31, 22.6%) or same (4/31, 12.9%) liver lobes or segments with gas collection in the dilated bile ducts. Conclusion: The CT manifestations of IBDA included signs of liver abscess, abnormalities of bile ducts, and signs showing their relationship. CT scanning was helpful in making comprehensive and accurate diagnosis of IBDA

    The changes of the bile ducts were reviewed retrospectively in 38 patients of clonorchiasis by ultrasonography and/or CT. Diagnosis was made in 13 patients by cholecystectomy and exploration of the common bile duct, another 2 patients by segmentectomy and wedge resection of the liver, and 23 patients by stool examination. 14 of 36 cases done ultrasonography showed the parallel channel sign, and small nodular echoes around the dilated bile ducts. And 3 cases showed the echoes of worm of clonorchis sinensis in the common bile duct. 22 of 36 cases showed the parallel channel signs only. All cases (11) done CT showed diffuse dilatation of the peripheral bile ducts. 5 of 11 cases showed ring or tubular contrast enhancement around the dilated bile ducts. In 2 cases of liver resection, the bile ducts showed adenomatous hyperplasia and severe periductal fibrosis. Proliferation of blood vessels and infiltration of inflammatory cells were also seen. So we consider that the increased echoes of the bile duct wall, small nodular echoes around the bile ducts were attributed to the bile duct dilatation, severe adenomatous hyperplasia and periductal fibrosis. The ring or tubular contrast enhancement of the dilated bile ducts seems to be caused by the marked periductal inflammation resulting in capillary proliferation and the periductal fibrosis.

  19. Bile Acid Signaling in Metabolic Disease and Drug Therapy

    Li, Tiangang

    2014-01-01

    Bile acids are the end products of cholesterol catabolism. Hepatic bile acid synthesis accounts for a major fraction of daily cholesterol turnover in humans. Biliary secretion of bile acids generates bile flow and facilitates hepatobiliary secretion of lipids, lipophilic metabolites, and xenobiotics. In the intestine, bile acids are essential for the absorption, transport, and metabolism of dietary fats and lipid-soluble vitamins. Extensive research in the last 2 decades has unveiled new functions of bile acids as signaling molecules and metabolic integrators. The bile acid–activated nuclear receptors farnesoid X receptor, pregnane X receptor, constitutive androstane receptor, vitamin D receptor, and G protein–coupled bile acid receptor play critical roles in the regulation of lipid, glucose, and energy metabolism, inflammation, and drug metabolism and detoxification. Bile acid synthesis exhibits a strong diurnal rhythm, which is entrained by fasting and refeeding as well as nutrient status and plays an important role for maintaining metabolic homeostasis. Recent research revealed an interaction of liver bile acids and gut microbiota in the regulation of liver metabolism. Circadian disturbance and altered gut microbiota contribute to the pathogenesis of liver diseases, inflammatory bowel diseases, nonalcoholic fatty liver disease, diabetes, and obesity. Bile acids and their derivatives are potential therapeutic agents for treating metabolic diseases of the liver. PMID:25073467

    Bile alcohols and bile acids from gallbladder bile of the Arapaima gigas, a large South American freshwater fish, were isolated by reversed-phase high-performance liquid chromatography. The structures of the major isolated compounds were determined by electrospray-tandem mass spectrometry and nuclear magnetic resonance using (1)H- and (13)C-NMR spectra. The novel bile salts identified were six variants of 2-hydroxy bile acids and bile alcohols in the 5α- and 5β-series, with 29% of all compounds having hydroxylation at C-2. Three C27 bile alcohols were present (as ester sulfates): (24ξ,25ξ)-5α-cholestan-2α,3α,7α,12α,24,26-hexol; (25ξ)-5β-cholestan-2β,3α,7α,12α,26,27-hexol, and (25ξ)-5α-cholestan-2α,3α,7α,12α,26,27-hexol. A single C27 bile acid was identified: (25ξ)-2α,3α,7α,12α-tetrahydroxy-5α-cholestan-26-oic acid, present as its taurine conjugate. Two novel C24 bile acids were identified: the 2α-hydroxy derivative of allochenodeoxycholic acid and the 2β-hydroxy derivative of cholic acid, both occurring as taurine conjugates. These studies extend previous work in establishing the natural occurrence of novel 2α- and 2β-hydroxy-C24 and C27 bile acids as well as C27 bile alcohols in both the normal (5β) as well as the (5α) "allo" A/B-ring juncture. The bile salt profile of A. gigas appears to be unique among vertebrates. Copyright © 2016. Published by Elsevier Inc.

    CT characteristics of spontaneous rupture of HCC (n=13) were reviewed retrospectively, and the value of emergency CT studies in this disease was evaluated. Especially, tumor protrusion ratio (TPR) and ascitic CT numbers were measured to for comparison with the data for unruptured HCCs and ordinary, (e.g., non-hemorrhagic) ascites (n=13). As a result, except for diffuse type HCCs, the TPR was significantly higher than for the unruptured HCCs. Nine cases had intraperitoneal HDAs, and the laterality of the HDAs corresponded with that of the ruptured tumors in 8 cases. Also, the ascitic CT numbers apart from the HDA were still higher than the ordinary ascites. Therefore, a high TPR, HDAs adjacent to the tumor, and elevated ascitic CT numbers are important CT manifestations indicating HCC rupture. Diffuse HCCs, however, require careful clinical evaluation.

    Full Text Available Abstract Introduction Chylothorax and chylous ascites are uncommon and usually associated with trauma or neoplasms. To the best of our knowledge, constrictive pericarditis leading to chylothorax and chylous ascites in a person infected with HIV has never previously been described. Case presentation A 39-year-old Thai man was referred to our institute with progressive dyspnea, edema and abdominal distension. His medical history included HIV infection and pulmonary tuberculosis that was complicated by tuberculous pericarditis and cardiac tamponade. Upon further investigation, we found constrictive pericarditis, chylothorax and chylous ascites. A pericardiectomy was performed which resulted in gradual resolution of the ascites and chylous effusion. Conclusions Although constrictive pericarditis is an exceptionally rare cause of chylothorax and chylous ascites, it should nonetheless be considered in the differential diagnosis as a potentially reversible cause.

    Full Text Available Abstract Background Although liver injury scale does not predict need for surgical intervention, a high-grade complex liver injury should alert the physician to expect an increased risk of hepatic complications following trauma. The aim of the current study was to define hepatic related morbidity in patients sustaining high-grade hepatic injuries that could be safely managed non-operatively. Patients and methods This is a retrospective study of patients with liver injury admitted to Hadassah-Hebrew University Medical Centre over a 10-year period. Grade 3-5 injuries were considered to be high grade. Collected data included the number and types of liver-related complications. Interventions which were required for these complications in patients who survived longer than 24 hours were analysed. Results Of 398 patients with liver trauma, 64 (16% were found to have high-grade liver injuries. Mechanism of injury was blunt trauma in 43 cases, and penetrating in 21. Forty patients (62% required operative treatment. Among survivors 22 patients (47.8% developed liver-related complications which required additional interventional treatment. Bilomas and bile leaks were diagnosed in 16 cases post-injury. The diagnosis of bile leaks was suspected with abdominal CT scan, which revealed intraabdominal collections (n = 6, and ascites (n = 2. Three patients had continuous biliary leak from intraabdominal drains left after laparotomy. Nine patients required ERCP with biliary stent placement, and 2 required percutaneous transhepatic biliary drainage. ERCP failed in one case. Four angioembolizations (AE were performed in 3 patients for rebleeding. Surgical treatment was found to be associated with higher complication rate. AE at admission was associated with a significantly higher rate of biliary complications. There were 24 deaths (37%, the majority from uncontrolled haemorrhage (18 patients. There were only 2 hepatic-related mortalities due to liver failure

    Numerous investigations on procalcitonin (PCT) have been carried out, although few with large sample size. To deal with the complexity of sepsis, an understanding of PCT in heterogeneous clinical conditions is required. Hospitalized patients aged 10-79 years were included in this retrospective and cross-sectional study. PCT tests were assayed within 2 days of blood culture. A total of 2952 cases (from 2538 patients) were enrolled in this study, including 440 cases in the 'positive BC' group, 123 cases in the 'positive body fluid culture' group, and 2389 cases in the 'negative all culture' group. Median PCT values were 4.53 ng/ml, 2.95 ng/ml, and 0.49 ng/ml, respectively. Median PCT values in the gram-negative BC group and gram-positive BC group, respectively, were 6.99 ng/ml and 2.96 ng/ml. Median PCT values in the 'positive hydrothorax culture' group, 'positive ascites culture' group, 'positive bile culture' group, and 'positive cerebrospinal fluid culture' group, respectively, were 1.39 ng/ml, 8.32 ng/ml, 5.98 ng/ml, and 0.46 ng/ml. In all, 357 cases were classified into the 'sepsis' group, 150 of them were classified into the 'severe sepsis' group. Median PCT values were 5.63 ng/ml and 11.06 ng/ml, respectively. PCT could be used in clinical algorithms to diagnose positive infections and sepsis. Different PCT levels could be related to different kinds of microbemia, different infection sites, and differing severity of sepsis.

    Bear bile has been used in Traditional Chinese Medicine (TCM) for thousands of years. Modern investigations showed that it has a wide range of pharmacological actions with little toxicological side effect and the pure compounds have been used for curing hepatic and biliary disorders for decades. However, extensive consumption of bear bile made bears endangered species. In the 1980's, bear farming was established in China to extract bear bile from living bears with "Free-dripping Fistula Technique". Bear farming is extremely inhumane and many bears died of illness such as chronic infections and liver cancer. Efforts are now given by non-governmental organizations, mass media and Chinese government to end bear farming ultimately. At the same time, systematic research has to be done to find an alternative for bear bile. In this review, we focused on the literature, laboratory and clinical results related to bear bile and its substitutes or alternative in English and Chinese databases. We examined the substitutes or alternative of bear bile from three aspects: pure compounds derived from bear bile, biles from other animals and herbs from TCM. We then discussed the strategy for stopping the trading of bear bile and issues of bear bile related to potential alternative candidates, existing problems in alternative research and work to be done in the future.

    1994-01-01

    This study was designed to evaluate serum bile acid measurements as indicatory, of liver function and/or hepatic fat infiltration in dairy cattle. Serum bile acid concentrations were measured in healthy dairy cattle at different stages of lactation after fasting or feeding. Bile acid concentrations were compared with liver fat content and sulfobromophthalein (BSP) half-life (T 1/2). Serum bile acid concentrations were higher in cows in early lactation and with higher daily milk production. Compared with prefasting values, bile acid concentrations were decreased at 8, 14, and 24 hours of fasting. Blood samples from fed cows at 1- to 2-hour intervals had wide and inconsistent variations in bile acid concentration. Because serum bile acids correlated well with BSP T 1/2, it is suggested that both measurements evaluate a similar aspect of liver function. Neither bile acids nor BSP T 1/2 correlated with differences in liver fat content among cows. Because of large variability in serum bile acid concentrations in fed cows and the lack of correlation of measured values with liver fat content, bile acid determinations do not appear useful for showing changes in hepatic function in fed cows with subclinical hepatic lipidosis nor serve as a screening test for this condition.

    Objective: To analyze the imaging features of hepatocellular carcinoma(HCC) with bile duct tumor thrombi. Methods: Thirteen patients with bile duct tumor thrombi proved pathologically underwent imaging examination. MR and CT were performed in 3 cases, and 2 cases had CT only and 8 cases had MRI only. Ultrasonography(US) was performed in all 13 patients. The accuracy of bile duct tumor thrombi detection was compared between US, CT and MRI with Fisher test. Results: Liver tumors and bile duct tumor thrombi were demonstrated in all patients on CT or MRI. Presence of intraluminal soft tissue mass was found in four of five cases on CT, and mild enhancement of the intraluminal mass in the arterial phase was noted, dilated bile duct distal to tumor thrombi was detected in all five patients. Eleven Tumor thrombi showed slight low signal intensity on T 1 WI, slight high signal intensity on T 2 WI, and mild to moderate contrast enhancement on the contrast-enhanced MR images. The MRCP findings of tumor thrombi were as follows: interruption, stricture of the bile ducts or irregular filling defect in the bile ducts with dilated intrahepatic ducts, bile duet was abruptly interrupted or showed a 'rat-tail' stricture (n=5); the common bile duct was filled with tumor thrombi, intrahepatic bile duct dilatation and missing common bile duct was noted on MRCP (n=2). Bile duct tumor thrombi were correctly diagnosed in 7 cases on US, and 12 cases on CT or MRI. Six cases were misdiagnosed or miss-diagnosed on US, and 4 cases were misdiagnosed on CT or MRI. There was no significant difference between US and CT/MRI in diagnosis of bile duct tumor thrombi (P=0.270). Conclusion: CT or MR imaging is useful for the diagnosis of HCC with biliary tumor thrombi and for evaluating the extension of thrombi. (authors)

Successful treatment of chronic hepatitis C in patients with advanced fibrosis or cirrhosis has significant benefits, including improvements in inflammation, fibrosis, and portal hypertension, with prevention of esophageal varices and clinical decompensation.Case: In this report, we present two patients with well-compensated hepatitis C cirrhosis who achieved an end-of-treatment response on a direct-acting antiviral therapy-based triple regimen for hepatitis C virus, but subsequently presented with new-onset ascites associated with virologic relapse.Conclusion: We propose that the development of ascites in this setting is due to the adverse impact of inflammation of the virologic relapse on portal hypertension. Our observation that ascites formation can be a manifestation of virologic relapse has potentially important clinical implications, as it highlights not only the importance of close monitoring of cirrhotic patients after achieving end-of-treatment response but also the impact of active inflammation on the severity of portal hypertension.Keywords: chronic hepatitis C, cirrhosis, virologic relapse, portal hypertension, 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.

    Purpose: To evaluate long-term results of treatment of benign bile duct strictures. Materials and methods: From February 1994 to November 2005, 21 patients (9 men, 12 women) with median age of 50.6 years (range 27-77 years) were indicated to percutaneous treatment of benign bile duct stricture. Stricture of hepatic ducts junction resulting from thermic injury during laparoscopic cholecystectomy was indication for treatment in one patient, stricture of hepaticojejunostomy was indication for treatment in all other patients. Clinical symptoms (obstructive jaundice, anicteric cholestasis, cholangitis or biliary cirrhosis) have appeared from 3 months to 12 years after surgery. Results: Initial internal/external biliary drainage was successful in 20 patients out of 21. These 20 patients after successful initial drainage were treated by balloon dilatation and long-term internal/external drainage. Sixteen patients were symptoms free during the follow-up. The relapse of clinical symptoms has appeared in four patients 9, 12, 14 and 24 months after treatment. One year primary clinical success rate of treatment for benign bile duct stricture was 94%. Additional two patients are symptoms free after redilatation (15 and 45 months). One patient is still in treatment, one patient died during secondary treatment period without interrelation with biliary intervention. The secondary clinical success rate is 100%. Conclusion: Benign bile duct strictures of hepatic ducts junction or biliary-enteric anastomosis are difficult to treat surgically and endoscopically inaccessible. Percutaneous treatment by balloon dilatation and long-term internal/external drainage is feasible in the majority of these patients. It is minimally invasive, safe and effective.

    Bile lecithins, solubilized in micellar bile salt and radiolabeled in the 1-acyl fatty acid, phosphorus, and choline positions, were infused in the small bowel of fasted rats. Absorption of each label was virtually complete after 24 h. However, these lecithins were extensively hydrolyzed in the bowel lumen as well as after absorption, and neither the fatty acid nor phosphorus was significantly retained in the enterohepatic circulation or reutilized for biliary lecithin synthesis. In contrast, while choline was also dissociated from absorbed lecithin, choline was instead retained in the liver, reincorporated into newly synthesized hepatic lecithin, and sercreted in biliary lecithin in 10-fold greater amounts than either the fatty acid or phosphorus. However, the extent of choline incorporation into bile lecithin was limited and was not further increased when free choline was directly injected into the portal vein. The data therefore suggest that although only choline of absorbed lecithin is retained in the enterohepatic circulation and preserved for new biliary lecithin synthesis, exogenous choline utilization is regulated by the size of the available hepatic pool.

    Full Text Available BilE has been reported as a bile resistance determinant that plays an important role in colonization of the gastrointestinal tract by Listeria monocytogenes, the causative agent of listeriosis. The mechanism(s by which BilE mediates bile resistance are unknown. BilE shares significant sequence similarity with ATP-binding cassette (ABC importers that contribute to virulence and stress responses by importing quaternary ammonium compounds that act as compatible solutes. Assays using related compounds have failed to demonstrate transport mediated by BilE. The putative substrate-binding domain (SBD of BilE was expressed in isolation and the crystal structure solved at 1.5 Å. Although the overall fold is characteristic of SBDs, the binding site varies considerably relative to the well-characterized homologs ProX from Archaeoglobus fulgidus and OpuBC and OpuCC from Bacillus subtilis. This suggests that BilE may bind an as-yet unknown ligand. Elucidation of the natural substrate of BilE could reveal a novel bile resistance mechanism.

    To evaluate the literature regarding the efficacy and safety of proton pump inhibitors (PPIs) when they are used in patients with cirrhosis and ascites. A literature search was conducted using MEDLINE (1966-May 2012) and Web of Science (1990-May 2012) with the terms proton pump inhibitor, antisecretory therapy, cirrhosis, ascites, spontaneous bacterial peritonitis, and Clostridium difficile. The search was restricted to articles published in English on the use of PPIs in humans. Reference citations from identified published articles were reviewed for relevant information. All articles in English identified from the data sources were evaluated for inclusion. One case series, 8 retrospective case-control trials, and 1 meta-analysis were identified. Cirrhosis may cause complications such as portal hypertension, esophageal varices, and ascites. Patients may be prescribed PPIs without clear indications or because of their propensity to develop upper gastrointestinal symptoms and bleeding. However, gastric acidity is a major nonspecific defense mechanism and there is insufficient evidence on the need for chronic acid suppression in patients with cirrhosis. It is postulated that the portal hypertensive environment in cirrhosis and the acid suppression from PPIs can increase the risk of spontaneous bacterial peritonitis and C. difficile infection in patients with cirrhosis with ascites. Several retrospective studies and 1 meta-analysis have confirmed this association. Patients with cirrhosis and ascites should be monitored carefully while on PPIs for a possible increased risk of infection from spontaneous bacterial peritonitis and C. difficile. Prospective randomized trials are needed to confirm this association. Clinicians should be aware of this lesser known adverse effect of PPIs.

    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.

    The metabolism of 64 Cu in some tissues of the bearing liver ascites tumor mice has been studied. The liver in normal and tumor bearing mice preferentially accumulates intravenous injection copper, however, the liver in the later mice accumulates much less copper than that of the former. It suggests that in the bearing ascites tumor mice, ascites tumor influences the metabolism of copper. It is found that the content of 64 Cu in the tumor cell is more than 85% in ascites tumor. Gel filtration profile of mice liver homogenate on Sephadex G-75 shows that injected 64 Cu is mainly bound with metallothionein. The tissues uptake of 125 I-labelled (Cd, Zn)-MT which is given in abdominal cavity are also reported. Of the tissues studied, the ascites tumor and kidney accumulate the highest concentration of given 125 I-MT, since over 20% of entire dose accumulated in them. After 125 I-MT is given, it soon goes into ascites tumor, and reaches the maximum in ascites as well as in tumor cell. Therefore, 125 I-MT can go through the membrane of tumor cell and reaches in the tumor cell

    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 peritonitis in hospitalized patient with cirrhosis and an independent predictor of short-term in-hospital mortality, even controlling for SBP and MELD.

    Full Text Available Adenomyomatous hyperplasia is rarely found in the extrahepatic bile duct. A 54-year-old man was referred to our center with a diagnosis of extrahepatic bile duct stenosis which had been detected by endoscopic retrograde choloangiopancreatography. Abdominal computed tomography revealed thickening of the wall of the middle extrahepatic bile duct, however no malignant cells were detected by cytology. Since bile duct carcinoma could not be ruled out, we performed resection of the extrahepatic duct accompanied by lymph node dissection. Histopathologically, the lesion was diagnosed as adenomyomatous hyperplasia of the extrahepatic bile duct. Present and previously reported cases showed the difficulty of making a diagnosis of adenomyomatous hyperplasia of the extrahepatic bile duct preoperatively or intraoperatively. Therefore, when adenomyomatous hyperplasia is suspected, a radical surgical procedure according to malignant disease may be necessary for definitive diagnosis.

    of drug from the cyclodextrin cavity by bile salts present in the small intestine. As bile salts in the intestine are present at concentrations above the critical micelle concentration, an understanding of the interaction between cyclodextrins and bile salts at such supramicellar concentrations (SMC......) is required for a better biopharmaceutical understanding of the release mechanism from orally dosed cyclodextrin complexes. To address this, experiments were conducted by isothermal titration calorimetry to determine how various b-cyclodextrins and bile salt interacts at SMC. Combined analysis of the current...... results and earlier data demonstrated that direct interactions between bile salt micelles and cyclodextrin were negligible. From this knowledge, an extended form of the UCD was suggested to describe the concentration of cyclodextrins to achieve full drug solubilization in the intestine where bile salts...

    Bile is the exocrine secretion of liver and synthesized by hepatocytes. It is drained into duodenum for the function of digestion or drained into gallbladder for of storage. Bile duct obstruction is a blockage in the tubes that carry bile to the gallbladder and small intestine. However, Bile duct ligation results in the changes of bile acids in serum, liver, urine, and feces1, 2. In this work, we demonstrate a novel technique to image this pathological condition by using a newly developed in vivo imaging system, which includes multiphoton microscopy and intravital hepatic imaging chamber. The images we acquired demonstrate the uptake, processing of 6-CFDA in hepatocytes and excretion of CF in the bile canaliculi. In addition to imaging, we can also measure kinetics of the green fluorescence intensity.

    To determine whether bile formation in the dog is an immature process at birth, several determinants of bile secretion were studied in anesthetized, bile duct-cannulated puppies of 0-42 days of age and adult dogs. Basal canalicular bile flow rate, estimated by 14 C-erythritol biliary clearance, averaged 0.182 microliter/min/g liver in 0-3 day-old puppies and increased to 0.324 and 0.461 microliter/min/g in puppies 7-21 and 28-42 days of age, respectively. Calculated ductular bile water reabsorption ( 14 C-erythritol biliary clearance-bile flow) was virtually absent in 0-3 day-old puppies, and averaged 0.017 and 0.092 microliter/min/g in puppies of 7-21 and 28-42 days of age, respectively. In adult dogs, ductular bile water reabsorption was 0.132 microliter/min/g. These functional deficiencies of the newborn dog were associated with an increased biliary permeability to 3 H-inulin which could not be accounted for solely by an increased solute diffusion due to the lower rate of canalicular bile flow. Administration of taurocholate up to 2000 nmol/min/kg produced in all animals a similar increase in canalicular bile flow and bile acid excretion, and was not associated with changes in ductular bile water reabsorption rate. These findings are interpreted to indicate that, in the dog, bile secretory function is immature at birth and develops during postnatal life

    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

    Based on a series of CT of the liver in 125 patients with hepatoma and 45 patients with metastatic hepatic tumors, the mode of dilatation of the intrahepatic bile duct was examined. In patients with hepatoma, partia dilatations of intrahepatic bile duct were more commonly seen than general dilatations. On the other hand, there was no case of partial dilatation of the intrahepatic bile duct in patients with metastatic hepatic tumors. It could be concluded that partial dilatation of the intrahepatic bile duct is an useful CT finding to make a diagnosis of hepatoma, particularly to differentiate hepatoma from metastatic hepatic tumor.

    Bile acids are well-recognized stimuli of glucagon-like peptide-1 (GLP-1) secretion. This action has been attributed to activation of the G protein-coupled bile acid receptor GPBAR1 (TGR5), although other potential bile acid sensors include the nuclear farnesoid receptor and the apical sodium......-coupled bile acid transporter ASBT. The aim of this study was to identify pathways important for GLP-1 release and to determine whether bile acids target their receptors on GLP-1-secreting L-cells from the apical or basolateral compartment. Using transgenic mice expressing fluorescent sensors specifically in L...... to either TLCA or TDCA. We conclude that the action of bile acids on GLP-1 secretion is predominantly mediated by GPBAR1 located on the basolateral L-cell membrane, suggesting that stimulation of gut hormone secretion may include postabsorptive mechanisms....

    Risk factors for bile leakage after hemihepatectomy are unknown. A prospectively maintained database review identified patients undergoing hemihepatectomy between 1 January 2009 and 30 September 2014. Patients were divided into B/C and non-B/C bile leakage groups. Risk factors for bile leakage were predicted and assessments of their impact on patients were made. Bile leakage occurred in 91 of the 297 patients (30.6%); 64 cases were classified as grade B bile leakage (21.5%) and three cases as grade C bile leakage (1.0%). Multivariate analysis confirmed that elevated preoperative alanine transaminase (ALT), positive bile culture during surgery, hilar bile duct plasty, bilioenteric anastomosis and laparoscopic surgery were risk factors for B/C grade bile leakage (P bile leakage (P bile leakage (P bile leakage group were higher than those in the non-B/C bile leakage group (P bile leakage group also required prolonged hospitalization (P 0.05). Patient with elevated preoperative ALT, positive bile cultures during surgery, hilar bile duct plasty, bilioenteric anastomosis and laparoscopic surgery are more likely to complicate bile leakage. We should use biliary drainage such as preoperative PTBD, ENBD or intraoperative Kehr's T-tube drainage to reduce and treat bile leakage in patients with high risk of bile leakage. © 2015 Royal Australasian College of Surgeons.

    Spontaneous perforation of the bile duct (SPBD) is a rare cause of acute abdominal pain during childhood. Pancreatico-biliary malfunction has been postulated to contribute to its etiology. Factors related to diagnosis and treatment and difference from the other common causes of acute abdominal pain are emphasized. Five patients (3 boys, 2 girls, mean age 4.6) were admitted with peritonitis and operated with initial diagnosis of perforated appendicitis. During laparotomy, SPBD was detected. Presentation, laboratory findings and operative technique of the patients were evaluated retrospectively. Common complaints were abdominal pain and bilious vomiting. Abdominal distention was present in all patients. Leukocytosis and mild hyperbilirubinemia were detected in 5, elevated serum transaminase levels in 4, hyperglycemia in 1 and constipation in 1 patient(s). Abdominal ultrasonography showed a large amount of free fluid. During laparotomy, sterile bile peritonitis was detected initially. After exploration, SPBD was seen. T-tube drainage of the bile duct was carried out. Patients were discharged after removal of the T-tubes. Pancreatico-biliary malfunction was detected in 4 of 5 patients. In patients with generalized peritonitis, elevated transaminase levels and hyperbilirubinemia, SPBD must be considered. Even though the T-tube drainage is the treatment of choice, Roux-en-Y hepatico-portoenterostomy may be mandatory in certain patients.

    Fibrates are hypolipidemic drugs that act as activators of peroxisome proliferator-activated receptor α (PPARα). In both humans and rodents, females were reported to be less responsive to fibrates than males. Previous studies on fibrates and PPARα usually involved male mice, but little has been done in females. The present study aimed to provide the first comprehensive analysis of the effects of clofibrate (CLOF) and PPARα on bile acid (BA) homeostasis in female mice. Study in WT male mice showed that a 4-day CLOF treatment increased liver weight, bile flow, and biliary BA excretion, but decreased total BAs in both serum and liver. In contrast, WT female mice were less susceptible to these CLOF-mediated responses observed in males. In WT female mice, CLOF decreased total BAs in the liver, but had little effect on the mRNAs of hepatic BA-related genes. Next, a comparative analysis between WT and PPARα-null female mice showed that lack of PPARα in female mice decreased total BAs in serum, but had little effect on total BAs in liver or bile. However, lack of PPARα in female mice increased mRNAs of BA synthetic enzymes (Cyp7a1, Cyp8b1, Cyp27a1, and Cyp7b1) and transporters (Ntcp, Oatp1a1, Oatp1b2, and Mrp3). Furthermore, the increase of Cyp7a1 in PPARα-null female mice was associated with an increase in liver Fxr-Shp-Lrh-1 signaling. In conclusion, female mice are resistant to CLOF-mediated effects on BA metabolism observed in males, which could be attributed to PPARα-mediated suppression in females on genes involved in BA synthesis and transport.

    Full Text Available Objective. To compare the functional activity of natural killer cells in peripheral blood and ascites from patients with different stages of colorectal and ovarian cancers and benign ovarian tumors. Material and methods. The study included 10 patients with stage IIIC ovarian cancer (FIGO, 2009, 5 patients with benign ovarian tumors (BOTs, and 15 patients with colorectal cancer (T2–4N0–2M0 . The control group consisted of 5 healthy donors. To evaluate the number and functional activity of NK-cells in peripheral blood and ascites, the FACS Canto II Flow Cytometer was used. Results. In peripheral blood of patients with ovarian and colorectal cancers, the relative number of activated NK-cells capable of secreting granzyme B (GB (CD56 + CD107a + GB + PF- was significantly lower and the proportion of degranulated NK-cells (CD56 + CD107a + GB- PF- was higher than those of healthy donors. Low total NK-cell counts in peripheral blood were a distinctive feature of ovarian cancer patients (p<0.05. The proportion of activated peripheral blood NK-cells, containing granules of cytolytic enzymes GB and perforin (PF increased with tumor growth. However, lymph node metastasis in patients with colorectal cancer did not affect the level and activation of NK-cells. The comparative analysis of NK-populations in patients with benign and malignant ovarian tumors revealed that the level of CD56 + cells was significantly higher in tumor ascites compared to peripheral blood. In patients with BTs, the levels of CD56 + CD107a + and activated CD56 + CD107a + GB-PF-degranulated cells was higher in ascites than in blood. In patients with ovarian cancer, the level of degranulated cells was higher in peripheral blood than in malignant ascites. Conclusion. The tumor cells and tumor microenvironment were found to affect the number and the functional activity of NK-cells.

    Commensal lactobacilli frequently produce bile salt hydrolase (Bsh) enzymes whose roles in intestinal survival are unclear. Twenty-six Lactobacillus salivarius strains from different sources all harbored a bsh1 allele on their respective megaplasmids. This allele was related to the plasmid-borne bsh1 gene of the probiotic strain UCC118. A second locus (bsh2) was found in the chromosomes of two strains that had higher bile resistance levels. Four Bsh1-encoding allele groups were identified, defined by truncations or deletions involving a conserved residue. In vitro analyses showed that this allelic variation was correlated with widely varying bile deconjugation phenotypes. Despite very low activity of the UCC118 Bsh1 enzyme, a mutant lacking this protein had significantly lower bile resistance, both in vitro and during intestinal transit in mice. However, the overall bile resistance phenotype of this and other strains was independent of the bsh1 allele type. Analysis of the L. salivarius transcriptome upon exposure to bile and cholate identified a multiplicity of stress response proteins and putative efflux proteins that appear to broadly compensate for, or mask, the effects of allelic variation of bsh genes. Bsh enzymes with different bile-degrading kinetics, though apparently not the primary determinants of bile resistance in L. salivarius, may have additional biological importance because of varying effects upon bile as a signaling molecule in the host.

    Bile acids have been implicated in the development of gastrointestinal malignancies. Both the specific nature of individual bile acids and their concentration appear key factors in the carcinogenic potency of bile. Using liquid chromatography mass spectrometry (LC-MS) we performed quantitative profiling of bile extracted directly from the common bile duct in 30 patients (15 patients with pancreatic cancer and 15 patients with benign disease). Separation and detection of bile acids was performed using a 1.7μm particle size reversed-phase C 18 LC column at a flow rate of 200μL/min with negative electrospray ionization MS. A significant difference (p=0.018) was seen in the concentration of unconjugated cholic acid in the malignant group (0.643mmol/L) compared to the benign group (0.022mmol/L), with an overall significant difference (p=0.04) seen in the level of total unconjugated bile acids in the malignant group (1.816mmol/L) compared to the benign group (0.069mmol/L). This finding may offer the possibility of both understanding the biology of cancer development in the pancreas, as well as offering a potential diagnostic avenue to explore. However, a larger study is necessary to confirm the alterations in bile acid profiles reported here and explore factors such as diet and microbial populations on the bile acid profiles of these patient groups.

    Carcinomas of the common bile duct are usually seen as dilatation of the bile duct proximal to a solid mass on CT. In the case reported here, the common bile duct cancer itself mimicked dilated common bile duct on CT because of massive necrosis. In a case of simulating dilated common bile duct on CT, and discrepancy between CT and ultrasonography or endoscopic retrograde cholangiopancreatography, a common bile duct cancer with massive necrosis should be included in the differential diagnosis.

    In order to determine the effects of intraoperative radiation therapy of the bile duct and surrounding tissues, seven adult dogs were subjected to laparotomy and intraoperative irradiation with 11 MeV electrons. Two animals were treated at each dose level of 2000, 3000, and 4500 rads. A single dog which received a laparotomy and sham irradiation served as a control. The irradiation field consisted of a 5 cm diameter circle encompassing the extrahepatic bile duct, portal vein, hepatic artery, and lateral duodenal wall. The animals were followed clinically for mor than 18 months after treatment, and autopsies were performed on dogs that died to assess radiation-induced complications or tissue damage. All dogs developed fibrosis and mural thickening of the common duct, which appeared by 6 weeks following irradiation and which was dose-related, being mild at low doses and more severe at high doses. Hepatic changes were seen as early as 6 weeks after irradiation, consisting of periportal inflammation and fibrosis. The hepatic changes appeared earliest at the highest doses. Frank biliary cirrhosis eventually developed at all dose levels. Duodenal fibrosis appeared in the irradiation portal, being most severe at the highest doses and in some animals resulting in duodenal obstruction. No changes were observed in irradiated portions of portal vein and hepatic artery at any dose level. It was concluded that intraoperative radiation therapy delivered to the region of the common duct leads to ductal fibrosis, partial biliary obstruction with secondary hepatic changes, and duodenal fibrosis if bowel wall is included in the field. Clinical use of intraoperative radiation therapy to the bile duct in humans may require routine use of biliary and duodenal bypass to prevent obstructive complications

    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.

  17. Isolation and characterization of tumor cells from the ascites of ovarian cancer patients: molecular phenotype of chemoresistant ovarian tumors.

    Full Text Available Tumor cells in ascites are a major source of disease recurrence in ovarian cancer patients. In an attempt to identify and profile the population of ascites cells obtained from ovarian cancer patients, a novel method was developed to separate adherent (AD and non-adherent (NAD cells in culture. Twenty-five patients were recruited to this study; 11 chemonaive (CN and 14 chemoresistant (CR. AD cells from both CN and CR patients exhibited mesenchymal morphology with an antigen profile of mesenchymal stem cells and fibroblasts. Conversely, NAD cells had an epithelial morphology with enhanced expression of cancer antigen 125 (CA125, epithelial cell adhesion molecule (EpCAM and cytokeratin 7. NAD cells developed infiltrating tumors and ascites within 12-14 weeks after intraperitoneal (i.p. injections into nude mice, whereas AD cells remained non-tumorigenic for up to 20 weeks. Subsequent comparison of selective epithelial, mesenchymal and cancer stem cell (CSC markers between AD and NAD populations of CN and CR patients demonstrated an enhanced trend in mRNA expression of E-cadherin, EpCAM, STAT3 and Oct4 in the NAD population of CR patients. A similar trend of enhanced mRNA expression of CD44, MMP9 and Oct4 was observed in the AD population of CR patients. Hence, using a novel purification method we demonstrate for the first time a distinct separation of ascites cells into epithelial tumorigenic and mesenchymal non-tumorigenic populations. We also demonstrate that cells from the ascites of CR patients are predominantly epithelial and show a trend towards increased mRNA expression of genes associated with CSCs, compared to cells isolated from the ascites of CN patients. As the tumor cells in the ascites of ovarian cancer patients play a dominant role in disease recurrence, a thorough understanding of the biology of the ascites microenvironment from CR and CN patients is essential for effective therapeutic interventions.

    Non-inbred rats of the Gifu strain were intraperitoneally challenged with Hirosaki sarcoma (Tetraploid type, 10 5 cells) after repeated immunization with gamma-irradiated (13,000 rads 60 Co) allogeneic non-viral tumors of ascites type (Tetraploid or diploid type of Hirosaki sarcoma, Usubuchi sarcoma or AH130). In rats immunized not only with the same tumor as the immunizing tumor but also with a different tumor, the growth of the challenge tumor was markedly inhibited as compared with the control in non-immunized rats. It is considered that these tumors retained common antigen(s) by the resistance to irradiation because of their form of ascites tumor. The marked cross-immunity in rats immunized with AH130 may be explained by the fact that gamma-irradiated AH130 cells were alive longer in the peritoneal cavity than other tumors on account of its high resistance to irradiation.

  19. Evolution of sarcoma 180 (ascitic tumor in mice infected with Schistosoma mansoni

    Directory of Open Access Journals (Sweden)

    Fausto Edmundo Lima Pereira

    1986-03-01

    Full Text Available Mice infected with 60 cercariae of Schistosoma mansoni were more resistant to the sarcoma 180 ascites tumor. Tumor inoculation was performed 50 days after schistosoma infection and the animals were observed and weighed at 48 hours intervals for development and progression of malignancy. In infected mice the weight gain (ascites formation started later and was shorter than in uninfected Controls. Also, the number of tumor cells into the peritoneal cavity 72h after tumor implantation was shorter in infected group than incontrols. This in creased resistance against a transplantable tumor probably is related to the effect of endotoxin on tumoricidal activity of macrophages activated by the infection. The immunodepression induced by Schistosoma mansoni infection enhances the proliferation of endogenous bacteria increasing the amount of endotoxin absorbed from the gut.

    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 litter moisture and litter nitrogen levels were not different (P > 0.05) among treatments at any sample interval.

    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.

    Purpose: To study the appearance of bile in clinical MR cholangiopancreatography (MRCP) with special reference to its chemical and physical properties. Material and Methods: Gallbladder bile was collected during surgery from 38 patients and studied with respect to chemical constituents. The relaxation rates 1/T1 and 1/T2 of bile were also determined in vitro. In 16 of these 38 patients, abdominal imaging was performed using MRCP as well as T1-weighted GE sequences. Results: For 9 of the 13 chemical parameters studied, a positive significant correlation with 1/T1 as well as 1/T2 was found. The median relaxation rates 1/T1 and 1/T2 were 0.76 and 1.48/s, respectively. The corresponding ranges were 0.38-3.13/s and 0.70-5.75/s, respectively. On the MRCP images a few patients showed gallbladder of poor visibility due to low signal-to-noise ratio. This coincided with a high relaxation rate 1/T2 of bile. On the T1-weighted GE sequences a few patients showed hyperintense gallbladder relative to liver, coinciding with high relaxation rates 1/T1 of bile. Conclusion: Bile was found to show a large interindividual variation with respect to relaxation rates 1/T1 and 1/T2. The relaxation rates increased with increasing amounts of substances in the bile. For some patients (11%) MRCP imaging is unsuccessful due to high relaxation rate of bile

    In forensic toxicology, alternative matrices to blood are useful in case of limited, unavailable or unusable blood sample, suspected postmortem redistribution or long drug intake-to-sampling interval. The present article provides an update on the state of knowledge for the use of bile in forensic toxicology, through a review of the Medline literature from 1970 to May 2015. Bile physiology and technical aspects of analysis (sampling, storage, sample preparation and analytical methods) are reported, to highlight specificities and consequences from an analytical and interpretative point of view. A table summarizes cause of death and quantification in bile and blood of 133 compounds from more than 200 case reports, providing a useful tool for forensic physicians and toxicologists involved in interpreting bile analysis. Qualitative and quantitative interpretation is discussed. As bile/blood concentration ratios are high for numerous molecules or metabolites, bile is a matrix of choice for screening when blood concentrations are low or non-detectable: e.g., cases of weak exposure or long intake-to-death interval. Quantitative applications have been little investigated, but small molecules with low bile/blood concentration ratios seem to be good candidates for quantitative bile-based interpretation. Further experimental data on the mechanism and properties of biliary extraction of xenobiotics of forensic interest are required to improve quantitative interpretation. Copyright © 2015 The Authors.

    Bile acids are synthesized in the liver and are the major component in bile. Impaired bile flow leads to cholestasis that is characterized by elevated levels of bile acid in the liver and serum, followed by hepatocyte and biliary injury. Although the causes of cholestasis have been extensively studied, the molecular mechanisms as to how bile acids initiate liver injury remain controversial. In this chapter, we summarize recent advances in the pathogenesis of bile acid induced liver injury. These include bile acid signaling pathways in hepatocytes as well as the response of cholangiocytes and innate immune cells in the liver in both patients with cholestasis and cholestatic animal models. We focus on how bile acids trigger the production of molecular mediators of neutrophil recruitment and the role of the inflammatory response in this pathological process. These advances point to a number of novel targets where drugs might be judged to be effective therapies for cholestatic liver injury. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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.

    Ehrlich ascites tumour cells were irradiated in vitro with thermal neutrons under aerobic and hypoxic conditions, and the survival of their reproductive capacity was assayed in vivo. Only a slight hypoxic protection was observed for thermal neutron irradiation with an oxygen enhancement ratio (OER) of 1.2, as compared with OER of 3.3 for ^Co-γ-rays. Absorbed dose of thermal neutrons was calculated by assuming that the energies of recoiled nuclei were completely absorbed within a cell nucleus....

    Aim: determination of the biological effect of the alpha emitter 211 At on cellular level as well as the assessment of dosimetric data in a tumour model in vivo. Methods: transplantation of malignant ascitic cells in mice intraperitoneally and estimation of tumour characteristics (doubling time of the cells, mean survival of the animals following an i.p. application of a defined tumour cell number). 211 At labelled human serum albumine microspheres B-20 (MSP) of variing activity were injected into tumour bearing mice intraperitoneally. The effectiveness of the therapy was evaluated by means of determination of the duration of cell cycle arrest as well as the microscopic analysis of the rate of abnormal mitotic cells due to radiation induced damage. Furthermore, dose dependence of survival was evaluated. Results: three days following the intraperitoneally application of 8 x 10 6 tumour cells, 50-600 kBq 211 At-MSP were applied into the abdominal cavity. Considering the volume of ascites at this time and the administered activity, dose calculations were performed. An activity of 50 kBq caused a dose of 0.84 Gy. The increase of radiation induced effect on ascitic tumour cells was correlated with the dose. Between the duration of the cell cycle arrest and the administered activity, a directly proportional correlation was found. The mean survival of non-treated animals was 16.9 ± 3.7 days. The prolongation of the survival was proportional to the activity administered. Using a dosage of 10 Gy, five animals out of 16 survived. Conclusion: therapy of malignant ascitic cells using 211 At-MSP was effective in vivo. For tumour therapy, the 211 At represents a highly effective alternative to usually applied beta emitters.

    To evaluate the effects of serial intravascular transfusions on RhD-alloimmunized fetuses with ascites/hydrops at the time of the first transfusion by measuring multiple hematological/biochemical blood variables. Thirty-one singleton pregnancies were referred for management of RhD alloimmunization. Seven fetuses had hydrops on presentation and were transfused immediately. The remainder underwent weekly ultrasound examinations, and fetal blood sampling and transfusion were performed on development of ascites. In the 104 samples collected overall from the 31 fetuses, glucose, uric acid, urea, creatinine, total protein, total and direct bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase, alkaline phosphatase, lactic dehydrogenase, amylase, pseudocholinesterase (PCHE), creatine kinase, triglycerides and cholesterol were measured and compared with a reference range for non-anemic fetuses. The median gestational age at first transfusion was 26 (range, 18-34) weeks. There were three fetal losses after the first transfusion, two of which were due to procedure-related complications; one further loss occurred. At the first transfusion fetal hematocrit, pO2, total protein, PCHE, creatinine and urea concentrations were significantly decreased compared to reference data, while total and direct bilirubin, AST, ALT, amylase, triglyceride and uric acid concentrations were increased. In all surviving fetuses ascites/hydrops had disappeared by the second transfusion. Fetal pO2, total protein, AST, ALT and PCHE concentrations had normalized by the third transfusion. Correction of fetal anemia did not affect the other variables. RhD-alloimmunized fetuses with ascites/hydrops at the time of the first transfusion had a survival rate of 87%. Alterations of several biochemical fetal blood indices are present at the first sampling/transfusion, but most variables normalize with intravascular transfusions. Copyright 2005 ISUOG.

    Effect of local X radiation with doses 0.05 and 0.15 C/kg on water transport in ascitic cells of Erlich carcinoma is studied in rats. To study water transport through cell membranes, tritium mark was used. It is concluded that radiation effect on water transport in cells of Erlich carcinoma may be related to change in ionic permittivity of the membrane, because small changes in transmembrane ion transport affect immediately the osmotic motion of water. 5 refs

    1986-01-01

    Technetium-99m DISIDA imaging was employed in 400 patients to differentiate obstruction of the common bile duct from medical and other surgical causes of hyperbilirubinemia. Sequential anterior images demonstrated variable degrees of liver uptake, yet there was no evidence of intrabiliary or extrabiliary radioactivity for at least 4 hr after injection in 25 patients. Twenty-three patients were surgically documented to have complete obstruction of the common bile duct. One patient had hepatitis, and another had sickle cell crisis without bile duct obstruction. The remaining patients had either partial or no obstruction of the common bile duct. We conclude that the presence of liver uptake without evident biliary excretion by 4 hr on cholescintigraphy is highly sensitive and predictive of total obstruction of the common bile duct

    A double or accessory common bile duct (ACBD) is a rare congenital anomaly. We report the case of a 60-year-old American Asian male, who was found to have a double or duplicated common bile duct after being admitted for evaluation of a pancreatic mass. A duplicated bile duct has the same mucosa histologically as a single bile duct. However, the opening of a duplicated bile duct lacks a sphincter allowing retrograde flow of gut contents which results in a higher probability of intraductal calculus formation. On rare occasions, it can predispose to liver abscesses, pancreatitis, pancreatic cancer, gallbladder cancer, gastric cancer, and ampullary cancer depending on the location of the opening of the ACBD. We present an integrative review of the limited cases of ACBD with correlation to the current case and discussion regarding the aspects of diagnosis and management.

    2017-04-01

    Full Text Available Bacteria must develop resistance to various inhospitable conditions in order to survive in the human gastrointestinal tract. Bile, which is secreted by the liver, and plays an important role in food digestion also has antimicrobial properties and is able to disrupt cellular homeostasis. Paradoxically, although bile is one of the guts defenses, many studies have reported that bacteria such as Vibrio parahaemolyticus can sense bile and use its presence as an environmental cue to upregulate virulence genes during infection. This article aims to discuss how bile is detected by V. parahaemolyticus and its role in regulating type III secretion system 2 leading to human infection. This bile–bacteria interaction pathway gives us a clearer understanding of the biochemical and structural analysis of the bacterial receptors involved in mediating a response to bile salts which appear to be a significant environmental cue during initiation of an infection.

    The aims of this study were to measure the levels of bile acids in patients with suspected ventilator-associated pneumonia (VAP) and provide a possible pathway for neutrophilic inflammation to explain its proinflammatory effect on the airway. Bile acid levels were measured by spectrophotometric enzymatic assay, and liquid chromatography mass spectrometry was used to quantify the major bile acids. Alveolar cells were grown on modified air-liquid interface culture inserts, and bile acids were then employed to stimulate the cells. Reverse transcriptase polymerase chain reaction and Western blots were used to determine the involved gene expression and protein levels. The mean (+/- SE) concentration of total bile acids in tracheal aspirates was 6.2 +/- 2.1 and 1.1 +/- 0.4 mumol/L/g sputum, respectively, for patients with and without VAP (p VAP group (p aspiration may reduce the intensity of neutrophilic inflammation in intubated and mechanically ventilated patients in the ICU.

    Abdominal irradiation has recently been shown to influence the uptake of hexoses, amino acids, fatty acids and cholesterol into the jejunum of rats. The present studies were undertaken with a previously validated in vitro technique to determine the effect of abdominal irradiation from a cesium source on the rates of uptake of six bile acids into the jejunum, ileum, and colon. The results show that: 1) there likely are multiple ileal carriers for bile acids: 2) abdominal irradiation has a variable effect on these carriers; 3) the passive permeability to bile acids varies with the bile acid and with the site along the intestine; and 4) abdominal irradiation is associated with a rise in the colonic permeability to only some bile acids

    The objective of the study was to examine the effects of consumption of different pectins from peach, quince, and apricot on bile flow and bile secretion of bile acids, cholesterol, phospholipids and bilirubin in rats. Six groups of nine rats were fed diets containing pectin 20 mg/kg once a day for two weeks. These groups of rats were compared with the group fed on physiological solution as a control and two groups fed on flamenol. Results of our study indicate that pectins, by decreasing cholesterol levels and enhancing bile acid secretion may cause increased hepatic synthesis of bile acids, phospholipids and reduced bilirubin synthesis. Among the studied pectins the apricot pectin shows in a very consistent lowering of cholesterol and bilirubin levels

    Chronic respiratory infections are a major cause of morbidity and mortality, most particularly in Cystic Fibrosis (CF) patients. The recent finding that gastro-esophageal reflux (GER) frequently occurs in CF patients led us to investigate the impact of bile on the behaviour of Pseudomonas aeruginosa and other CF-associated respiratory pathogens. Bile increased biofilm formation, Type Six Secretion, and quorum sensing in P. aeruginosa, all of which are associated with the switch from acute to persistent infection. Furthermore, bile negatively influenced Type Three Secretion and swarming motility in P. aeruginosa, phenotypes associated with acute infection. Bile also modulated biofilm formation in a range of other CF-associated respiratory pathogens, including Burkholderia cepacia and Staphylococcus aureus. Therefore, our results suggest that GER-derived bile may be a host determinant contributing to chronic respiratory infection. PMID:23049911

    Cyst of the common bile duct, the most frequent variant of cystic dilatation of the extrahepatic biliary tract, represents a serious diagnostic problem. 13 children with cysts of the common bile duct were studied by the method of dynamic scintigraphy with sup(99m)Tc-HIDA. The scintigraphic picture was characterized by the following signs: sacculated or spheroidal dilatation of the common bile duct, dilatation of the left or both lobular bile ducts, absence of the gall bladder visualization. Change of indicators of the hepatic function and the time of interstinal visualization reflects both the disorder of distal parts permeability and the degree of cyst drainage. An experience of radioisotropic cholegraphy application reveals, that the efficiency of preoperational diagnosis of cysts of the common bile duct increases as a result of the more accurate evaluation of the dynamic of improvement of absorptive-excretory hepatic function after different variants of operations

    Despite the overwhelming prevalence of cholelithiasis, many health care professionals are not familiar with the basic pathophysiology of gallstone formation. This article provides an overview of the biochemical pathways related to bile, with a focus on the physical chemistry of bile. We describe the important factors in bile synthesis and secretion that affect the composition of bile and consequently its liquid state. Within this biochemical background lies the foundation for understanding the clinical and sonographic manifestation of cholelithiasis, including the pathophysiology of cholesterol crystallization, gallbladder sludge, and gallstones. There is a brief discussion of the clinical manifestations of inflammatory and obstructive cholestasis and the impact on bile metabolism and subsequently on liver function tests. Despite being the key modality in diagnosing cholelithiasis, ultrasound has a limited role in the characterization of stone composition.

    A new method for the selective determination of the main serum bile acids has been developed. Serum samples with added 14 C-labeled bile acid were submitted to deproteinization, alkaline hydrolysis, methylation, and were then chromatographed on alumina before acetylation with 2 microliters of [ 3 H]acetic anhydride. Excess reagent was eliminated by evaporation; elimination of residual tritiated contaminants and separation of the doubly labeled bile acid derivatives were obtained by thin-layer chromatography, column chromatography on Lipidex 5000, and crystallization. The sensitivity of the method is about 10 pmol of each bile acid. Analyses of seven sera with normal or elevated concentration of bile acids by the proposed method and gas-liquid chromatography showed a close correlation

    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 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.

    Radiation responses of Bp8 sarcoma ascites tumour cells with differences in membrane fatty acid composition was studied. The cells were grown i.p. in NMRI mice and their membrane composition was changed in response to different dietary regimes provided to the hosts. Cell survival, varied insignificantly between the four dietary groups, while repair capacity differed significantly. Increased repair capacity was observed for ascites cells grown in animals on diets enriched in sunflower seed oil and coconut oil, compared with cells from mice fed the hydrogenated lard diet or from cells from the control animals. The membrane fatty acid composition of the cells from the two dietary groups with increased levels of repair capacity differed extensively, and in general there was no correlation between radiation response and the membrane fatty acid composition of the four groups. For coconut oil and control groups with marked differences in membrane fatty acid composition, the effects of irradiation on ascites tumour growth rate and cell cycle distribution were followed in vivo. For none of the parameters was an effect on membrane fatty acid composition on radiation response observed. (author)

    Full Text Available Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs’ syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs’ syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices.

    Full Text Available Transplante renal artery stenosis (TRAS is defined as renal artery diameter reduction of more than 50%, which causes a reduction in glomerular filtration rate and a rise in plasma creatinine concentration. Current treatments are endovascular-balloon-angioplasty and stent implantation. We present the case with renal artery stenosis and ascites was treated with endovascular-balloon-dilatation. A 52-year-old female patient who was admitted to the nephrology clinic five months after the transplantation with blood pressure: 180/110 mmHg, ascites , and the chest radiograph did not show a pulmonary oedema, creatinine: 1.69 mg/dL other laboratory tests were normal. An occlusion of 80 % in a segment and the stenosis was reduced to 10 % by endovascular-balloon dilation. Following endovascular-balloon dilation, arterial blood pressure were normal and no ascites. Endovascular balloon dilation is minimally invasive method that is also successful, contemporary and valid procedures with easy applicability for the management of TRAS.

    1994-09-01

    Laparoscopic cholecystectomy is both resulting in a slightly higher incidence of biliary lesions and a change of prevalence of the type of lesions. Damage to the biliary system occurs in 4 different types: The most severe case is the lesion with a structural defect of the hepatic or common bile duct with (IVa) or without (IVb) vascular injury. Tangential lesions without structural loss of the duct should be denominated as type III (IIIa with additional lesion to the vessels, type IIIb without). Type II comprehends late strictures without obvious intraoperative trauma to the duct. Type I includes immediate biliary fistulae of usually good prognosis. The increasing prevalence of structural defects of the bile ducts appears to be a peculiarity of laparoscopic cholecystectomy necessitating highly demanding operative repair. In the majority of cases, hepatico-jejunostomy or even intraparenchymatous anastomoses are required. Adaptation of well proven principles of open surgery is the best prevention of biliary lesions in laparoscopic cholecystectomy as well as the readiness to convert early to the open procedure.

  13. Bile pigments in pulmonary and vascular disease

    2012-03-01

    Full Text Available The bile pigments, biliverdin and bilirubin, are endogenously-derived substances generated during enzymatic heme degradation. These compounds have been shown to act as chemical antioxidants in vitro. Bilirubin formed in tissues circulates in the serum, prior to undergoing hepatic conjugation and biliary excretion. The excess production of bilirubin has been associated with neurotoxicity, in particular to the newborn. Nevertheless, clinical evidence suggests that mild states of hyperbilirubinemia may be beneficial in protecting against cardiovascular disease in adults. Pharmacological application of either bilirubin and/or its biological precursor biliverdin, can provide therapeutic benefit in several animal models of cardiovascular and pulmonary disease. Furthermore, biliverdin and bilirubin can confer protection against ischemia/reperfusion injury and graft rejection secondary to organ transplantation in animal models. Several possible mechanisms for these effects have been proposed, including direct antioxidant and scavenging effects, and modulation of signaling pathways regulating inflammation, apoptosis, cell proliferation, and immune responses. The practicality and therapeutic-effectiveness of bile pigment application to humans remains unclear.

    Bear bile has been a well-known Chinese medicine for thousands of years. Because of the endangered species protection, the concept on substitutes for bear bile was proposed decades ago. Based on their chemical composition and pharmacologic actions, artificial bear bile, bile from other animals, synthetic compounds, and medicinal plants may be the promising candidates to replace bear bile for the similar therapeutic purpose. Accumulating research evidence has indicated that these potential substitutes for bear bile have displayed the same therapeutic effects as bear bile. However, stopping the use of bear bile is a challenging task. In this review, we extensively searched PubMed and CNKI for literatures, focusing on comparative studies between bear bile and its substitutes for the treatment of liver diseases. Recent research progress in potential substitutes for bear bile in the last decade is summarized, and a strategy for the use of substitutes for bear bile is discussed carefully. PMID:27087822

    A valid and efficient reversed-phase ultra-fast liquid chromatography method was developed for the simultaneous determination of 13 bile acids in the bile of three mammal species, including rat, pig and human gallstone patients. Chromatographic separation was performed with a Shim-pack XR-ODS column, and the mobile phase consisted of acetonitrile and potassium phosphate buffer (pH 2.6) at a flow rate of 0.5 mL min(-1). The linear detection range of most bile acids ranged from 2 to 600 ng µL(-1) with a good correlation coefficient (>0.9995). The precision of each bile acid was bile acids were separated in 15 min with satisfactory resolution, and the total analysis time was 18 min, including equilibration. The method was successfully applied in rapid screening of bile samples from the three mammals. Significant metabolic frameworks of bile acids among various species were observed, whereas considerable quantitative variations in both inter- and intraspecies were also observed, especially for gallstone patients. Our results suggest that detecting the change of bile acid profiles could be applied for the diagnosis of gallstone disease. © Crown copyright 2014.

    Objectives: Thickened greater omentum is encountered with high frequency in patients with ascites. The purpose of our study was to assess the utility of greater omentum biopsy under the guidance of ultrasound (US) in tracing the origin of unclear ascites and differentiating benign and malignant ascites. Materials and methods: We retrospectively reviewed our institutional database for all records of greater omentum biopsy cases. One hundred and ninety-four patients with unclear ascites and thickened greater omentum were included in the study. The sonograms of greater omentum were evaluated before undergoing the ultrasound-guided biopsy and a biopsy was considered successful if a specific benign or malignant diagnosis was rendered by the pathologist. Results: Successful biopsy was rendered for 182 biopsy procedures (93.8%, 182/194) including tuberculosis (n = 114), chronic inflammation (n = 3), metastases (n = 58), malignant mesothelioma (n = 6) and pseudomyxoma peritonei (n = 1). Twelve biopsies were non-diagnostic. According to the results of biopsy and follow-up, the sensitivity and specificity of biopsy in distinguishing malignant ascites from benign ascities were respectively 95.6% (65/68) and 92.9% (117/126). The greater omentum of 84 cases of tuberculous peritonitis showed 'cerebral fissure' sign and was well seen as an omental cake infiltrated with irregular nodules when involved by carcinomatosis. No 'cerebral fissure' sign was observed in peritoneal carcinomatosis. The sensitivity and specificity of this sign in indicating the existence of tuberculous peritonitis were 73.5% (89/121) and 100% (73/73). Moreover, if the specific 'cerebral fissure' sign was combined with the biopsy results, the specificity of biopsy in distinguishing malignant ascites from benign ascits increased to 96.8% (122/126). Conclusion: Ultrasound-guided biopsy of greater omentum is an important and effective method to diagnose the unclear ascites for

The levels of reduction in bacterial count (Log cfu/ml of the acid and acid-bile-NaCl adapted isolates obtained in simulated gastric fluid ranged from 0.64-3.06 and 0.36-2.43 logarithmic units after 120 min of incubation. There was no significant difference between the viability of the acid-bile-NaCl-tolerant isolates and the original strains in simulated small intestinal condition except for Bifidobacterium adolescentis (p<0.05. The presence of 15 ml of supernatants of acid-bile-NaCl-adapted isolates and also those of the initial Bifidobacterium strains inhibited pathogenic bacterial growth for 24 hrs. Probiotic bacteria with improved ability to survive in harsh gastrointestinal environment could be obtained by subsequent treatment of the strains in acid, bile salts and NaCl environments.

    In man bile acid synthesis has a distinct circadian rhythm but the relationship of this rhythm to feedback inhibition by bile acid is unknown. We measured bile acid synthesis as release of 14CO2 from [26-14C]cholesterol every 2 hr in three normal volunteers during five separate 24-hr periods. Data were fitted by computer to a cosine curve to estimate amplitude and acrophase of the circadian rhythm. In an additional six volunteers, we measured synthesis every 2 hr from 8:00 a.m. to 4:00 p.m. only. During the control period, amplitude (expressed as percentage of mean synthesis) averaged 52% and acrophase averaged 6:49 a.m. During administration of ursodeoxycholic acid (15 mg per kg per day), synthesis averaged 126% of baseline (p less than 0.1), amplitude averaged 43% and acrophase averaged 6:20 a.m. During administration of chenodeoxycholic acid (15 mg per kg per day), synthesis averaged 43% of baseline (p less than 0.001), amplitude averaged 53% and acrophase averaged 9:04 a.m. Addition of prednisone to this regimen of chenodeoxycholic acid to eliminate release of 14CO2 from corticosteroid hormone synthesis resulted in a mean amplitude of 62% and a mean acrophase of 6:50 a.m., values very similar to those in the baseline period. Administration of prednisone alone also did not significantly alter the baseline amplitude (40%) or acrophase (6:28 a.m.). We conclude that neither chenodeoxycholic acid nor ursodeoxycholic acid significantly alters the circadian rhythm of bile acid synthesis in man

    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.

    It is well accepted that intrahepatic bile ducts lie in front of corresponding portal vein branches. Since the authors' clinical experience with US was different, they studied 18 normal necropsy cadaver livers. The common bile duct, main portal vein, and hepatic artery were cannulated and injected respectively with air, dilute contrast medium, and mineral oil. The livers were then examined in anatomic position with CT. In the left lobe of the liver, the bile ducts were anterior to the portal vein in seven cases, posterior in seven cases, and were tortuous both anterior and posterior in three cases. In the right lobe, the bile ducts were anterior in nine cases, posterior in five cases, tortuous in one case, and not seen in two cases. In the porta hepatis, the bile ducts were anterior in eight cases, posterior in one case, tortuous in five cases, and not seen in three cases. Histologic specimens confirmed the anterior and posterior location of the bile ducts relative to the portal veins. In conclusion, intrahepatic bile ducts can be either anterior or posterior to the corresponding portal vein branches

    A nitrated cancrinite-type zeolite was synthesized from zeolite X, NaOH and NaNO 3 solutions under autogeneous pressure at 80 deg. C for 48 h. This zeolite was characterized by X-ray diffraction (XRD), FT-IR-spectroscopy, scanning electron microscopy (SEM) and BET surface area. XRD, SEM and FT-IR confirmed the presence of nitrated cancrinite-type zeolite without other collateral phases as sodalite. Then, this sodium zeolite was exchanged with potassium and calcium cations and finally, these modified zeolites were reacted with biliar solutions from human gallbladder. Several factors such as: mass of used cancrinite, nature of the exchanged cation and reaction time of the cancrinite-bile solution interactions were studied. The composition of bile solutions (bile acids, phospholipids and bilirubin) was analyzed before and after the cancrinite-bile solution reaction. Results showed that the components of the bile were notably reduced after the contact with solids. Ca-cancrinite, 120 min of reaction time and 500 mg of solids were the best conditions determined for the bile acid reduction in human bile. When the modified zeolites were compared with the commercial cholestyramine, it was found that zeolites were more active than the latter. These zeolites may be an alternative choice to diminish cholesterol levels in hypercholesterolemic patients

    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.

    Objective: To evaluate the diagnostic value about the dilated extent of bile duct and gallbladder in low biliary obstructive diseases. Methods: CT and ERCP findings of 105 patients with low biliary obstructive disease were retrospectively analyzed. The dilated extent of intrahepatic and extra- hepatic bile duct and gallbladder were classified into seven types: Type I: severe dilatation of intrahepatic and extrahepatic bile duct and gallbladder; Type II: severe dilatation of extrahepatic bile duct and gallbladder and slight dilated intrahapetic bile duct; Type III: severe dilatation of intrahepatic and extrahepatic bile duct without or slight dilatation of gallbladder; Type IV: severe extrahepatic bile duct dilatation without or slight dilatation of intrahepatic bile duct and gallbladder; Type V: severe intrahepatic bile duct dilatation without or with slight dilatation of extrahepatic bile duct and gallbladder; Type VI: severe gallbladder dilatation without or with slight intrahepatic and extra- hepatic bile duct dilatation; Type VII: without or with slight dilatation of intrahepatic and extrahepatic bile duct and gallbladder. The biliary system dilated extent of low biliary obstructive disease on CT and ERCP were compared with results of clinical, operation, and pathology. Results: Thirty-three cases of tumor and 72 cases of non-tumor were proved by clinical and operation in 105 patients with low biliary obstructive disease. In 33 tumor patients, 16 patients were identified as Type I, 10 patients Type II, 4 patients Type III, 1 patient Type IV, 2 patients Type VII. In 72 non-tumor patients, 4 patients were identified as Type I, 4 patients Type II, 9 patients Type III, 33 patients Type IV, 2 patients Type V, 11 patients Type VI, 19 patients Type VII. A large difference between I, II type and III-VII type biliary dilatation existed in tumor and non-tumor group (χ 2 =47.33, P<0.01). Conclusion:Low obstructive biliary diseases are closely correlated with the dilated

    Key points Acute biliary pancreatitis is a sudden and severe condition initiated by bile reflux into the pancreas.Bile acids are known to induce Ca2+ signals and necrosis in isolated pancreatic acinar cells but the effects of bile acids on stellate cells are unexplored.Here we show that cholate and taurocholate elicit more dramatic Ca2+ signals and necrosis in stellate cells compared to the adjacent acinar cells in pancreatic lobules; whereas taurolithocholic acid 3‐sulfate primarily affects acinar cells.Ca2+ signals and necrosis are strongly dependent on extracellular Ca2+ as well as Na+; and Na+‐dependent transport plays an important role in the overall bile acid uptake in pancreatic stellate cells.Bile acid‐mediated pancreatic damage can be further escalated by bradykinin‐induced signals in stellate cells and thus killing of stellate cells by bile acids might have important implications in acute biliary pancreatitis. Abstract Acute biliary pancreatitis, caused by bile reflux into the pancreas, is a serious condition characterised by premature activation of digestive enzymes within acinar cells, followed by necrosis and inflammation. Bile acids are known to induce pathological Ca2+ signals and necrosis in acinar cells. However, bile acid‐elicited signalling events in stellate cells remain unexplored. This is the first study to demonstrate the pathophysiological effects of bile acids on stellate cells in two experimental models: ex vivo (mouse pancreatic lobules) and in vitro (human cells). Sodium cholate and taurocholate induced cytosolic Ca2+ elevations in stellate cells, larger than those elicited simultaneously in the neighbouring acinar cells. In contrast, taurolithocholic acid 3‐sulfate (TLC‐S), known to induce Ca2+ oscillations in acinar cells, had only minor effects on stellate cells in lobules. The dependence of the Ca2+ signals on extracellular Na+ and the presence of sodium–taurocholate cotransporting polypeptide (NTCP) indicate a Na

    To evaluate the role of bile routing modification on the beneficial effects of gastric bypass surgery on glucose and energy metabolism. Gastric bypass surgery (GBP) promotes early improvements in glucose and energy homeostasis in obese diabetic patients. A suggested mechanism associates a decrease in hepatic glucose production to an enhanced intestinal gluconeogenesis. Moreover, plasma bile acids are elevated after GBP and bile acids are inhibitors of gluconeogenesis. In male Sprague-Dawley rats, we performed bile diversions from the bile duct to the midjejunum or the mid-ileum to match the modified bile delivery in the gut occurring in GBP. Body weight, food intake, glucose tolerance, insulin sensitivity, and food preference were analyzed. The expression of gluconeogenesis genes was evaluated in both the liver and the intestine. Bile diversions mimicking GBP promote an increase in plasma bile acids and a marked improvement in glucose control. Bile bioavailability modification is causal because a bile acid sequestrant suppresses the beneficial effects of bile diversions on glucose control. In agreement with the inhibitory role of bile acids on gluconeogenesis, bile diversions promote a blunting in hepatic glucose production, whereas intestinal gluconeogenesis is increased in the gut segments devoid of bile. In rats fed a high-fat-high-sucrose diet, bile diversions improve glucose control and dramatically decrease food intake because of an acquired disinterest in fatty food. This study shows that bile routing modification is a key mechanistic feature in the beneficial outcomes of GBP.

    Listeria monocytogenes is a Gram-positive facultative anaerobe that is the causative agent of the disease listeriosis. The infectious ability of this bacterium is dependent upon resistance to stressors encountered within the gastrointestinal tract, including bile. Previous studies have indicated bile salt hydrolase activity increases under anaerobic conditions, suggesting anaerobic conditions influence stress responses. Therefore, the goal of this study was to determine if reduced oxygen availability increased bile resistance of L. monocytogenes. Four strains representing three serovars were evaluated for changes in viability and proteome expression following exposure to bile in aerobic or anaerobic conditions. Viability for F2365 (serovar 4b), EGD-e (serovar 1/2a), and 10403S (serovar 1/2a) increased following exposure to 10% porcine bile under anaerobic conditions (P 0.05) in bile resistance between aerobic and anaerobic conditions, indicating that oxygen availability does not influence resistance in this strain. The proteomic analysis indicated F2365 and EGD-e had an increased expression of proteins associated with cell envelope and membrane bioenergetics under anaerobic conditions, including thioredoxin-disulfide reductase and cell division proteins. Interestingly, HCC23 had an increase in several dehydrogenases following exposure to bile under aerobic conditions, suggesting that the NADH:NAD+ is altered and may impact bile resistance. Variations were observed in the expression of the cell shape proteins between strains, which corresponded to morphological differences observed by scanning electron microscopy. These data indicate that oxygen availability influences bile resistance. Further research is needed to decipher how these changes in metabolism impact pathogenicity in vivo and also the impact that this has on susceptibility of a host to listeriosis. PMID:27274623

    To describe the radiologic features of computed tomography (CT) in hepatocellular carcinoma (HCC) with bile duct involvement. We retrospectively analyzed the two phase spiral CT findings of 31 patients in whom HCC with bile duct invasion (n=3D28) or compression (n=3D3), was diagnosed. Eight of these underwent follow up CT after transarterial chemoembolization. We analyzed the size, type, location, enhancement pattern, and lipiodol retention of parenchymal and intraductal masses, as well as their lymphadenopathy. In all patients with bile duct invasion, single or multiple masses were demonstrated in the bile ducts. Intraductal masses showed the same enhancement characteristics as the parenchymal mass (kappa 0.550, p less than 0.001), and were contiguous to this mass. In 14 of 28 patients, intraductal masses filled the peripheral intrahepatic bile ducts and extended to the common bile ducts. In the other 14, the parenchymal mass extended to the area of the porta hepatis and then directly invaded the large ducts. In nine of the 28 patients, there was a hypoattenuated cleft between the intraductal mass and ductal wall. In six, a parenchymal mass was not apparent (n=3D2), or was smaller than 2cm (n=3D4). In five of eight patients (62.5%), follow-up CT after transarterial chemoembolization showed compact or partial lipiodol retention within the intraductal mass. In patients with bile duct compression, perihilar lymph nodes were noted along with the dilated intrahepatic duct but no intra ductal mass was demonstrated in the duct. Hepatocellular carcinomas cause bile duct dilatation either by direct invasion or by extrinsic compression of the bile duct with surrounding enlarged nodes. For the diagnosis of this condition, CT is helpful. (author)

    From 1984 through 1986, six patients with extrahepatic bile duct tumor were treated preoperatively with intraluminal irradiation of the bile duct. There were no unresectable cases and pathological examination of the surgical specimens showed moderate to remarkable tumor regression in all cases. Postoperative biliary tract hemorrhage occurred in 2 of 3 patients who received 60 Gy at a point 7.5 mm from the center of the source. With accurate preoperative diagnosis of the tumor extent and careful setting of the target area of intraluminal irradiation, improved local tumor control of extrahepatic bile duct tumor can be expected with this method.

    Pericentral hepatocytes excrete bile acids more slowly and biotransform them more than periportal cells. This may reflect adaptation to low pericentral bile acid concentration or may be intrinsic. The authors studied two models in which pericentral bile acid concentrations are high: the 72-h choledocho-caval shunt (CCS) rat and the 3- to 4-wk-old rat. Livers were perfused forward or backward to assess periportal or pericentral hepatocyte function. Taurodeoxycholate (TDC) was infused at 32 nmol x min -1 x g liver -1 , and a bolus of [ 3 H]TDC was given to assess metabolism and excretion of bile acids. In CCS livers perfused backward, pericentral cells resembled periportal cells of controls in that time to excrete 50% of administered [ 3 H]-TDC (t 50 ) was reduced by two-thirds and [ 3 H]TDC biotransformation was reduced by about half. In young livers t 50 was half that of adult livers when perfused backward. Biotransformation, however, was not reduced. Young livers biotransformed more than adult controls for any given residence time of bile acid in the liver. They conclude that the difference between pericentral and perioportal cells as regards bile acid processing is adaptive. Livers from young rats biotransform more bile acid than those from controls under similar conditions

    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.

    Full Text Available Cholestasis is characterized by accumulation of bile acids and inflammation, causing hepatocellular damage. Still, liver damage markers are highest in acute cholestasis and drop when this condition becomes chronic, indicating that hepatocytes adapt towards the hostile environment. This may be explained by a hormetic response in hepatocytes that limits cell death during cholestasis.To investigate the mechanisms that underlie the hormetic response that protect hepatocytes against experimental cholestatic conditions.HepG2.rNtcp cells were preconditioned (24 h with sub-apoptotic concentrations (0.1-50 μM of various bile acids, the superoxide donor menadione, TNF-α or the Farsenoid X Receptor agonist GW4064, followed by a challenge with the apoptosis-inducing bile acid glycochenodeoxycholic acid (GCDCA; 200 μM for 4 h, menadione (50 μM, 6 h or cytokine mixture (CM; 6 h. Levels of apoptotic and necrotic cell death, mRNA expression of the bile salt export pump (ABCB11 and bile acid sensors, as well as intracellular GCDCA levels were analyzed.Preconditioning with the pro-apoptotic bile acids GCDCA, taurocholic acid, or the protective bile acids (tauroursodeoxycholic acid reduced GCDCA-induced caspase-3/7 activity in HepG2.rNtcp cells. Bile acid preconditioning did not induce significant levels of necrosis in GCDCA-challenged HepG2.rNtcp cells. In contrast, preconditioning with cholic acid, menadione or TNF-α potentiated GCDCA-induced apoptosis. GCDCA preconditioning specifically reduced GCDCA-induced cell death and not CM- or menadione-induced apoptosis. The hormetic effect of GCDCA preconditioning was concentration- and time-dependent. GCDCA-, CDCA- and GW4064- preconditioning enhanced ABCB11 mRNA levels, but in contrast to the bile acids, GW4064 did not significantly reduce GCDCA-induced caspase-3/7 activity. The GCDCA challenge strongly increased intracellular levels of this bile acid, which was not lowered by GCDCA

    Between February 1993 and March 1994 a prospective descriptive study was carried out in 25 cirrhotic patients (three of them on two occasions with clinical or ultrasonographic ascites; they were hospitalized in the Internal Medicine ward of San Vicente de Paúl Hospital, in Medellín, Colombia, because of decompensation. All of them went through diagnostic paracentesis with cytologic, bacteriologic and chemical studies. Average age was 43.9 years (13 to 77 years, 13 were women (52% and 12 men (48%. Infection of the ascitic fluid was found in 11 cases (39.3%, namely: Bacterascites 6 cases (monomicrobial 3 cases (27.3%, polymicrobial 3 cases (27.3%», spontaneous bacterial peritonitis 3 cases (polymicrobial 2 cases (18.2% and monomicrobial1 case (9.1 %» and neutrocytic ascites 2 cases (18.2%. Seventy two percent of the infectious episodes caused fever (p < 0.01 and in 46% there was abdominal pain (p < 0.1. AII patients with infected ascites belonged to Child's classification C. Serum albumin levellower than 2 g/dl was a risk factor for developing infection. Escherichia coli was cultivated on 5 occasions (45.5%, viridans group of Streptococci in 5 (45.5%, anaerobes in 3 (27.3% and other bacteria in 3 (27.3%. Mortality due to infected ascites was 27.3% (3 cases, comparable to that produced by other causes that was 29.4% (5/17. We conclude that ascitic fluid infection is a common complication in decompensated cirrhotic patients. Thecardinal clinical signs are fever and abdominal pain. The frequent isolation of E. coli and viridans group Streptococci has to be taken into account for the initiation of antibiotic therapy in cases with clinical suspicion.

    In the most countries, breast cancer is still the most important cancer among women. It is known that Ehrlich Ascites Tumour is experimental breast cancer model in animal. The cells used in the study are hyper diploid line of Ehrlich Ascites Tumour (EAT) cells, initially provided to us from Institute of Pathology, Koln University. In the present study, an hyper diploid line which is estrogen receptor positive was used. An anthracycline-derived antibiotic, Daunorubicin (DNR, Cerubidine) is one of the clinically used anticancer drugs. DNR has been used alone or in combination with other cytotoxic agents against a variety of animal and human tumours. In vitro cell culture studies show that DNR enters the cell nuclei, inhibits nucleic acid synthesis, and arrest cell division. Tamoxifen (TAM, Nolvadex) is a semi-synthetical estrogen antagonist, used in the management of pre and post menopausal breast cancer. This drug bind to intracellular estrogen receptors, and prevents endogenous estrogens from binding to their own receptors. It is known that Ehrlich Ascites Tumour is experimental breast cancer model in animal. The cells used in the study are hyper diploid line of EAT cells initially provided to us from Institute of Pathology, Koln University. In the present study, an hyper diploid line which is Estrogen Receptor (+) was used. Estrogen Receptor levels were studied by the methods of Lippman and Huff and Raynaud et al. with minor modifications. Estrogen Receptor activity as demonstrated by dextran-coated charcoal technique is closely correlated with the clinical ability of Tamoxifen to inhibit tumour growth

    Full Text Available Introduction: Spontaneous common bile duct perforation is an uncommon clinical entity in both adults and children. Few case reports have been published since the first clinical description in 1882. Our work has been reported in line with SCARE criteria. Presentation of case: Herein, we describe the case of a 28 year-old female who suffered spontaneous common bile duct perforation while admitted for choledocholithiasis. Discussion: The perforation occurred while in-hospital, and extensive imaging and laboratory tests characterized the disease in detail. To our knowledge, this is the first report of spontaneous common bile duct perforation witnessed from pre-perforation through definitive management. Conclusion: Physicians and Surgeons should seek out this uncommon diagnosis in the patient with suspected Choledocholithiasis who suddenly become peritoneal on physical exam so that definitive care can be expedited.

    We describe a patient with sudden onset of abdominal pain and ascites, leading to the diagnosis of autosomal dominant polycystic kidney disease (ADPKD). Her presentation was consistent with acute liver cyst rupture as the cause of her acute illness. A review of literature on polycystic liver disease in patients with ADPKD and current management strategies are presented. This case alerts physicians that ADPKD could occasionally present as an acute abdomen; cyst rupture related to ADPKD may be considered in the differential diagnoses of acute abdomen.

    DNA of Ehrlich ascites carcinoma cells prepared under conditions that were highly denaturing for proteins but not for DNA, contained a group of nonhistone residual proteins. The amount of these proteins increased during DNA replication. The DNA-protein complex observed was sensitive to proteolytic enzymes and/or SH-reagents. γ-irradiation cells with moderate doses leads to a decrease in the amount of DNA-protein complexes. High-dose gamma-irradiation produces enhanced linking of chromosomal proteins with DNA. (author)

    With an enzyme degradative technique, isotope inequilibrium of glucose metabolites was demonstrated in intact cells and particle-free supernatants of Ehrlich ascites tumor using I- 14 C-glucose as tracer. Inequilibrium was found between glucose and glucose-6-phosphate, glucose and fructose-6-phosphate, glucose and 6-phosphogluconate, while glucose-6-phosphate and fructose-6-phosphate were found to be in near equilibrium within the incubation time investigated. Glucose and lactate were found to be in near equilibrium after 8 min in intact cells. Calculations based on the equilibrium levels found, showed that these inequilibria could not be explained by the effects of the pentose cycle. (U.S.)

    A ribosome-bound poly (U) polymerase from Ehrlich ascites tumor cells is partially characterized. It adds UMPs to RNAs terminating in U-(3')-OH. The UMP-rich segments added reach average sizes of up to 18 nucleotides. CTP is strongly inhibitory to the enzyme. The main endogenous primers are low molecular weight RNAs which are found, after the addition of UMPs, mostly in the 6-8 S range. Some evidence suggests that a 5 S rRNA or polysome-associated 7 S RNA could be the main endogenous primers. (Author) [pt

    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.

    Tumor and normal tissue uptake of 51 Cr- or 57 Co-labelled bleomycin (BLEO) and tallysomycin (TLM) was compared in female solid Ehrlich ascites tumor mice of Swiss strain. The complexes were administered intraperitoneally: 30-50 μg of each complex with an activity of 40-120 μCi. Activity distribution factors (ADF) and tumor/non-tumor ratios for blood, bone, skeletal muscles, kidneys and liver were determined. The ratios were generally higher for complexes labelled with 57 Co than for the 51 Cr-labelled ones; bleomycin appears equivalent or superior to tallysomycin. (orig.) [de

    Seven icteric dogs were determined to have bile duct obstruction secondary to chronic pancreatitis. All dogs had histories of intermittent vomiting and diarrhea. Alkaline phosphatase and alanine aminotransferase activities and total bilirubin concentrations were markedly elevated. Diagnosis was based on exploratory laparotomy and histological examination. Each dog had a 3 to 10 cm mass in the body of the pancreas and obstruction of the common bile duct. Three dogs treated with pancreatectomy,...

    Objective evaluation tools for assessing the effectiveness of stenting in palliative treatment of malignant biliary obstruction are not satisfactory. Effects of biliary stenting on liver volume change have never been studied. We aimed to use volumetry to analyze liver volume changes after endoscopic stenting in bile duct cancer according to the location and number of stents. Retrospective review. University hospital. Patients with a diagnosis of hilar or distal bile duct cancer and who underwent biliary metal stenting. ERCP with self-expandable metal stent placement. Liver volume change after biliary stenting and its comparison according to the location (hilar vs distal common bile duct) and number (hilar bilateral vs hilar unilateral). There were 60 patients; 31 were treated for hilar bile duct cancer (13 for bilateral stent and 18 for unilateral stent) and 29 for distal bile duct cancer. Overall mean follow-up duration was 11.7 ± 4.9 weeks. Liver volume increased 17.4 ± 24.1%. The rate of liver growth was rapid during the early period from 4 to 8 weeks. Stenting in hilar bile duct cancer tended to increase liver volume more than distal biliary stents (22.5% vs 11.9%, P = .091). In hilar bile duct cancer, unilateral and bilateral stents showed similar liver volume increases (20.1% and 25.8%, respectively; P = .512). Single center, retrospective. Biliary stenting markedly increased liver volume in both hilar and distal bile duct cancer. Our data suggest that liver volume assessment could be a useful tool for evaluating stent efficacy.

  15. Bile sensor: from the lab to the market

    In 1988 the idea of measuring bile in the stomach and in the oesophagus via optical fibers was conceived and patented in collaboration with physicians from the University of Florence. The working principle is based on the spectrophotometric properties of the bile which contains some pigments with definite absorption properties. Bilirubin is the main pigment and it is characterized by an absorption peak in the blue region: therefore it is possible to detect optically the bile in the stomach by optically detecting bilirubin. The possibility of measuring bile reflux directly measuring the presence of bile represented a winning aspect in comparison with the traditional techniques (pH-metry, cholescintigraphy, bile acid assessment in aspirates); on the contrary the new technique had to overcome the traditional 'cultural' barriers constituted by the conservative attitude of clinicians concerning any innovative technology. The realization of the first laboratory prototype demonstrates the feasibility and validity of the proposed optical method. Then many years were necessary to arrive at the definitive and marketable product. The history of Bilitec 2000 is described, with the purpose to stress how a laboratory prototype is still very far from the market.

    Full Text Available Background: Bile gastritis (gastropathy is a kind of gastritis which is caused by reflux of bile contents through duodenum on stomach. It can occur spontaneously without any former gastric surgeries which affect sphincter of pylorus. The positive impact of some certain drugs such as prokinetic agents e.g. metoclopramide, Proton-pump inhibitors (PPIs, cholestyramine and sucralfate in treating bile gastritis has been confirmed. This study has been conducted in order to analyze the effect of ursodeoxycholic acid (UDCA, which is a harmless drug, on patients with the bile gastritis. Materials and Methods: In this clinical trial, all patients with dyspepsia who were qualified to undertake endoscopy were enrolled and then 60 patients with bile gastritis were selected for the study. The patients were divided into two groups; a group was treated by UDCA, omeprazole and sucralfate and another one was treated with placebo, omeprazole and sucralfate for two weeks. Finally, at the end of the third week of treatment patients were examined.Results: A total of sixty 19-70 year-old patients (Mean: 46 years old included in this study. At the end of the study, there was not found any meaningful difference between the two groups in terms of pain intensity, heartburn intensity, severity of bloating, vomiting and early satiety; however, each group independently showed improvement of the mentioned indices after termination of the treatment (p=0.0005.Conclusion: Adding UDCA to the standard treatment (sucralfate is not clinically effective in curing the bile gastritis.

    Pacific lampreys Lampetra tridentata are in decline throughout much of their historical range in the Columbia River basin. In support of restoration efforts, we tested whether larval and adult lamprey bile acids serve as migratory and spawning pheromones in adult Pacific lampreys, as they do in sea lampreys Petromyzon marinus. The olfactory sensitivity of adult Pacific lampreys to lamprey bile acids was measured by electro-olfactogram recording from the time of their capture in the spring until their spawning in June of the following year. As controls, we tested L-arginine and a non-lamprey bile acid, taurolithocholic acid 3-sulfate (TLS). Migrating adult Pacific lampreys were highly sensitive to petromyzonol sulfate (a component of the sea lamprey migratory pheromone) and 3-keto petromyzonol sulfate (a component of the sea lamprey sex pheromone) when first captured. This sensitivity persisted throughout their long migratory and overwinter holding period before declining to nearly unmeasurable levels by the time of spawning. The absolute magnitudes of adult Pacific lamprey responses to lamprey bile acids were smaller than those of the sea lamprey, and unlike the sea lamprey, the Pacific lamprey did not appear to detect TLS. No sexual dimorphism was noted in olfactory sensitivity. Thus, Pacific lampreys are broadly similar to sea lampreys in showing sensitivity to the major lamprey bile acids but apparently differ in having a longer period of sensitivity to those acids. The potential utility of bile acid-like pheromones in the restoration of Pacific lampreys warrants their further investigation in this species.
