    Refractory ascites is defined as ascites that does not recede or that recurs shortly after therapeutic paracentesis, despite sodium restriction and diuretic treatment. To date, there is no approved medical therapy specifically for refractory ascites. Management of these patients is based upon procedures such as large-volume paracentesis and transjugular intrahepatic portosystemic shunts (TIPS), which temporarily alleviate symptoms but are not curative. These patients have a poor prognosis and are at risk for a series of complications that are associated with the condition or are secondary to therapy. The most common complications include spontaneous bacterial peritonitis, hepatic hydrothorax, spontaneous bacterial empyema, and umbilical hernia. The predicted survival rate is as low as 50% at 1 year, and prognosis worsens as patients present with comorbidities such as hepatorenal syndrome, renal failure, and hepatocellular carcinoma. The only curative treatment is liver transplantation, though current studies have shown that TIPS also increases survival.

    Ascites is a common complication of hepatic cirrhosis and portal hypertension. Patients present systemic and splanchnic circulation disorders, which cause central hypovolemia and arterial hypotension, with the subsequent activation of vasoconstrictor systems and increased renal reabsorption of sodium and water. Approximately 5%-10% of patients present refractory ascites. Refractory ascites is considered when it is not controllable with standard dietary (sodium restriction) and diuretic (furosemide up to 160 mg a day and spironolactone up to 400mg a day) treatment or when patients present adverse effects due to diuretics that impede their administration at optimum dosages. The current therapeutic options for these patients are repeated evacuative paracentesis and the percutaneous intrahepatic portosystemic shunt. Despite these treatments, refractory ascites has a poor prognosis; patients should therefore be assessed for liver transplantation.

    Refractory ascites is a serious post-hepatectomy complication in cirrhotic patients with hepatocellular carcinoma (HCC). In order to avoid this complication, surgeons should preserve as much liver parenchyma as possible in performing hepatectomy in such patients. However, we still occasionally encounter refractory ascites even after limited or small hepatectomy. The aim of this study was to identify risk factors for post-hepatectomy refractory ascites in cirrhotic patients, focusing on limited or small hepatectomy. The data of 73 cirrhotic patients with HCC who underwent limited or small hepatectomy were analyzed. Limited or small hepatectomy was defined as hepatectomy equal to or of less than subsegmentectomy. We compared the clinicopathological factors between patients with and without postoperative refractory ascites. Fourteen cirrhotic patients suffered postoperative refractory ascites. Total cholesterol, duration of operation, duration of Pringle maneuver, resection of segment VII, intraoperative blood loss, and intraoperative blood transfusion were found to be significant risk factors for postoperative refractory ascites in univariate analyses. Multivariate analysis revealed that resection of segment VII was an independent risk factor. Resection of segment VII necessitates extensive dissection of the right triangular or coronary ligaments, which could explain that it was an independent risk factor for post-hepatectomy refractory ascites. Surgeons should avoid extensive dissection of these ligaments in order to avoid this detrimental complication. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Background Large volume paracentesis is found to be safer and more effective for the treatment of tense ascites compared with larger-than-usual doses of diuretics according to studies. The objectives of the study was to evaluate patients with refractory ascites regarding clinical profile, technique of paracentesis, complications, amount of ascites drained, prognosis and co-morbid conditions associated with it. Methods Retrospective study was performed including patients between January 2011 and December 2013 with data pooled from total of five hospitals. A total of 4,389 paracenteses were performed on the 1,218 patients with a mean volume of 4,900 ± 2,795 mL ascitic fluid drained. Blind technique, ultrasound-guided technique of paracentesis and pig tail catheter drainage were evaluated. Diabetes mellitus data from available patients and data regarding co-morbidities were analyzed. Coagulation abnormalities in patients were studied. Results Study group age ranged from 34 to 79 years, and alcohol is the main cause of cirrhosis. Dyslipidemia was observed in 1,080 patients (88.66%). At the time of inclusion in the study, 40% of the patients had ≥ 2 other cirrhosis-related complications and 20% of the study population had ≥ 3 complications. Early complications occurred in 27.5% (337) of patients and late complications constituted 16.83% (205 patients). Conclusions Even with abnormal coagulation, paracentesis is a safe procedure. But significant co-morbidities should be addressed with care in cirrhosis patients. Ultrasound guidance during the procedure whenever required should be encouraged. PMID:27785301

    Abstract Ascites is the most common complication related to cirrhosis and is associated with increased morbidity and mortality. Ascites is a consequence of the loss of compensatory mechanisms to maintain the overall effective arterial blood volume due to worsening splanchnic arterial vasodilation as a result of clinically significant portal hypertension. In order to maintain effective arterial blood volume, vasoconstrictor and antinatriuretic pathways are activated, which increase overall sodium and fluid retention. As a result of progressive splanchnic arterial vasodilation, intestinal capillary pressure increases and results in the formation of protein-poor fluid within the abdominal cavity due to increased capillary permeability from the hepatic sinusoidal hypertension. In some patients, the fluid can translocate across diaphragmatic fenestrations into the pleural space, leading to hepatic hydrothorax. In addition, infectious complications such as spontaneous bacterial peritonitis can occur. Eventually, as the liver disease progresses related to higher portal pressures, loss of a compensatory cardiac output and further splanchnic vasodilation, kidney function becomes compromised from worsening renal vasoconstriction as well as the development of impaired solute-free water excretion and severe sodium retention. These mechanisms then translate into significant clinical complications, such as refractory ascites, hepatorenal syndrome and hyponatremia, and all are linked to increased short-term mortality. Currently, liver transplantation is the only curative option for this spectrum of clinical manifestations but ongoing research has led to further insight on alternative approaches. This review will further explore the current understanding on the pathophysiology and management of ascites as well as expand on two advanced clinical consequences of advanced liver disease, refractory ascites and hyponatremia.

    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.

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

    Refractory ascites is recognized in patients with various conditions. Although intravenous reinjection of ascitic fluid after its filtration and concentration (IRA) is an effective method of treating this condition, many associated side-effects have been reported. We performed extracorporeal ultrafiltration of ascitic fluid (EUA) to demonstrate the efficacy and advantages of this method of treating refractory ascites. EUA was performed in seven patients with hepatic cirrhosis (3 cases), lupus nephritis, diabetic nephropathy, and carcinomatous peritonitis (2 cases) for a total of 122 sessions. IRA was performed in three of these seven patients for a total of 12 sessions. The average volumes of ascitic fluid removed by EUA and IRA were 3.94+/-1.45 litres and 2.87+/-0.69 litres (mean+/-SD) respectively. Although chills and acute renal failure were recognized as complications of IRA in five and one sessions respectively, the only complication of EUA was severe intra-abdominal haemorrhage, which resolved spontaneously. In spite of rapid and massive removal of ascitic fluid (maximum 2.0 litres per 15 min), significant changes in blood pressure were not noted during EUA. In three patients (hepatic cirrhosis, lupus nephritis, and diabetic nephropathy), de novo production of ascitic fluid disappeared. In one patient with hepatic cirrhosis and chronic renal failure on haemodialysis, 67 sessions of EUA have been performed under stable conditions. Three patients (one case of hepatic cirrhosis and two cases of carcinomatous peritonitis) died of their primary diseases. We conclude that EUA is a useful method for the treatment of massive refractory ascites.

    Cirrhotic patients with refractory ascites (RA) can be treated with repeated large volume paracentesis (LVP), with the insertion of a transjugular intrahepatic portosystemic shunt (TIPS) or with liver transplantation. However, side effects and complications of these therapeutic options, as well as organ shortage, warrant the development of novel treatments. The automated low-flow ascites pump (alfapump®) is a subcutaneously-implanted novel battery-driven device that pumps ascitic fluid from the peritoneal cavity into the urinary bladder. Ascites can therefore be aspirated in a time- and volume-controlled mode and evacuated by urination. Here we review the currently available data about patient selection, efficacy and safety of the alfapump and provide recommendations for the management of patients treated with this new method.

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

    Some patients with ascites due to liver cirrhosis become no longer responsive to diuretics. Once other causes of ascites such as portal vein thrombosis, malignancy or infection and non-compliance with medications and low sodium diet have been excluded, the diagnosis of refractory ascites can be made based on strict criteria. Patients with refractory ascites have very poor prognosis and therefore referral for consideration for liver transplantation should be initiated. Search for reversible components of the underlying liver pathology should be undertaken and targeted therapy, when available, should be considered. Currently, serial large volume paracentesis (LVP) and transjugular intrahepatic portasystemic stent-shunt (TIPS) are the two mainstay treatment options for refractory ascites. Other treatment options are available but not widely used either because they carry high morbidity and mortality (most surgical options) rates, or are new interventions that have shown promise but still need further evaluation. In this comprehensive review, we describe the evaluation and management of patients with refractory ascites from the prospective of the practicing physician. PMID:19115470

    Abdominal wall hernia is a common feature of decompensated liver cirrhosis and frequently causes life-threatening complications or severe pain. However, there have been no data reported on postoperative mortality, hepatic functional deterioration and recurrence rate according to Child-Turcotte-Pugh (CTP) class and to the presence of refractory ascites. The study population comprised 53 liver cirrhosis patients who underwent hernia repair operation. Comparisons were made of 30-day mortality among the different CTP classes, and between those with or without refractory ascites. Liver function was also analyzed just before the operation, in the immediate postoperative period, and in the remote postoperative period. Seventeen patients were in CTP class A, 27 patients in class B, and 9 patients in class C. The median follow-up duration was 24 months. There was single 30-day postoperative mortality in class C, and no CTP class deterioration after 30 days of operation. There was no mortality or recurrences in 17 patients with medically refractory ascites. The difference in 30-day mortality according to CTP class and the presence of refractory ascites did not show statistical significance (P = 0.17 and 0.97, respectively). Hernia operation could be done safely in CTP class A and B with low rate of recurrences, and there was no definitive increase in the operative risk in class C. In addition, refractory ascites did not increase operative risk and recurrence rate. Therefore, surgical repair might be recommended even in patients with refractory ascites and poor hepatic function to prevent life-threatening complications or severe pain.

    A 47 year-old male with a history of refractory ascites presented to our centre complaining of dyspnoea, abdominal distention, and weight gain. He was admitted under a medical team for investigation and management. Work-up excluded all common aetiologies of ascites. Echocardiography revealed severe aortic regurgitation (AR) with a dilated left ventricle but no right heart pathology or pulmonary hypertension. He underwent mechanical aortic valve replacement. Intra-operatively, a prolapsing left coronary leaflet of the aortic valve with frayed edges raised suspicion of resolved infective endocarditis. Postoperative course was uneventful. Following replacement of the aortic valve, the patient was completely free of ascites. This case demonstrates that ascites can be an unusual clinical presentation of severe aortic regurgitation, which may respond to aortic valve replacement. Crown Copyright © 2013.

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

    PubMed

    2015-11-07

    Hyponatremia is a frequent complication of advanced cirrhosis with ascites associated with increased morbidity and mortality. It is caused by an impairment in the renal capacity to eliminate solute-free water and is considered to be related to persistent secretion of vasopressin despite low serum osmolality. This nonosmotic release of vasopressin is mediated by the autonomic nervous system, which senses the underfilling of arterial vascular component. This reduction of effective arterial blood volume is closely related to the development of ascites. Although the short-time effects of vasopressin V2 receptor antagonists (vaptans) on hyponatremia and ascites have been repeatedly reported, their effects on the long-term management of cirrhotic ascites have not been established yet. Considering that their effects on water diuresis and their safety are limited by severe underfilling state of patients, cautious approaches with adequate monitoring are needed to advanced cirrhosis. Proper indication, adequate doses and new possibility of combination therapy should be explored in the future controlled study. As hyponatremia is frequent obstacle to ascites management, judicious combination with low-dose diuretics may decrease the incidence of refractory ascites. Although vaptans show much promise in the treatment of advanced cirrhosis, the problem of high cost should be solved for the future.

    Splanchnic arterial vasodilatation and subsequent activation of anti-natriuretic and vasoconstrictive mechanisms have an important role in cirrhotic ascites. The aim of this study was to evaluate the effects of midodrine, clonidine, and their combination on systemic hemodynamics, renal function, and control of ascites in patients with cirrhosis and refractory or recurrent ascites. Sixty cirrhotic patients with refractory or recurrent ascites were prospectively studied after long-term administration of clonidine (n=15) or midodrine (n=15), or both (n=15) plus standard medical therapy (SMT), or SMT alone (n=15), in a randomized controlled trial at a tertiary center. A significant increase in urinary volume, urinary sodium excretion, mean arterial pressure, and decrease in plasma renin activity (P<0.05) was noted after 1 month. There was also a significant decrease in cardiac output (P<0.05) and increase in systemic vascular resistance (P<0.05) in all groups, except clonidine. There was no change in glomerular filtration rate and model for end-stage liver disease score. Midodrine and a combination of midodrine and clonidine plus SMT were superior to SMT alone in the control of ascites (P=0.05), and there was a trend towards better control of ascites in the clonidine group (P=0.1). The mortality and frequency of various complications were similar in all groups. These results suggest that midodrine, clonidine, and their combination plus SMT improves the systemic hemodynamics without any renal or hepatic dysfunction, and is superior to SMT alone for the control of ascites. However, the combination therapy was not superior to midodrine or clonidine alone.

    Ascites is a common clinical manifestation of cirrhotic portal hypertension, and about 60%-80% of cirrhotic patients develop the symptom of ascites within 10 years. Once ascites occurs, the 5-year survival rate is reduced from 80% to 50%. With the progression of liver diseases, approximately 5%-10% of patients with ascites develop refractory ascites, and the median survival time is only 6-12 months. This article reviews the definition and diagnosis of refractory ascites, evaluation of prognostic factors, and treatment regimens, including large-volume paracentesis combined with protein supplementation, transjugular intrahepatic portosystemic shunt, and liver transplantation.

    Non hepatic origin of refractory ascites is not a rarity. Hemolytic anemias are known to cause inspissated bile and biliary obstruction. Distal biliary obstruction can lead to biliary perforation. The authors report a case of hereditary spherocytosis leading to inspissated bile causing bile duct perforation and biliary ascites. A high index of suspicion for biliary ascites should be kept in a child with refractory ascites in the setting of progressive ascites with decreasing bilirubin. Ascitic fluid bilirubin analysis will clinch the diagnosis. Surgical repair is the optimal management.

    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.

    Splanchnic arterial vasodilatation plays an important role in cirrhotic ascites. The aim of this study was to evaluate the effects of long term administration of midodrine on systemic hemodynamics, renal function, and control of ascites in patients with cirrhosis and refractory or recurrent ascites. Forty cirrhotic patients with refractory or recurrent ascites were prospectively studied after long term administration of midodrine plus standard medical therapy (n=20) or standard medical therapy alone (n=20) in a randomized controlled trial at a tertiary centre. A significant increase in urinary volume, urinary sodium excretion, mean arterial pressure, and decrease in plasma renin activity (p<0.05) was noted after 1 month of midodrine administration. There was also a significant decrease in cardiac output and an increase in systemic vascular resistance after midodrine therapy at 3 months (p<0.05). There was no change in glomerular filtration rate and model for end-stage liver disease (MELD) score. Midodrine plus standard medical therapy was significantly superior to standard medical therapy alone in the control of ascites (p=0.013) at 3 months. The mortality rate in the standard medical therapy group was significantly higher than the midodrine group (p<0.046). There was no significant difference in the frequency of various complications at the end of follow-up. The results of this randomized pilot study suggest that midodrine plus standard medical therapy improves the systemic hemodynamics without any renal or hepatic dysfunction in these patients and is superior to standard medical therapy alone for the control of ascites.

    Ascites, the commonest complication of cirrhosis, leads to frequent hospitalisations. Refractory ascites confers a median survival of 6 months without liver transplantation. In many, the management remains palliative (large-volume paracentesis). Despite calls for improvement, palliative and end-of-life care is not yet integrated into end-stage liver disease. Long-term abdominal drains are a palliative strategy in malignant ascites, but not end-stage liver disease. A retrospective, single centre, case series review was performed of patients undergoing long-term abdominal drain placement for refractory ascites secondary to end-stage liver disease at a large teaching hospital between August 2011 and March 2013. Case management: Patients with end-stage liver disease and refractory ascites, where liver transplantation was not an option, were considered for long-term abdominal drains. Seven patients underwent successful long-term abdominal drain insertion after multi-professional assessment. Case outcome: Following long-term abdominal drain insertion, mean hospital attendances reduced to 1 (0-4) from 9 (4-21), with none for ascites management. Median survival after long-term abdominal drain insertion was 29 days (8-219). The complication rate was low and none life threatening. Palliative and end-of-life care needs in end-stage liver disease remain under-addressed. Our data suggest that long-term abdominal drains may be a safe and effective palliative intervention in end-stage liver disease. Prospective randomised controlled trials comparing large-volume paracentesis versus long-term abdominal drains in refractory ascites secondary to end-stage liver disease are warranted.

    AIM: To evaluate the efficacy and safety of tolvaptan to treat refractory ascites in decompensated liver cirrhosis patients with or without further complications, such as hepatorenal syndrome and/or hepatocellular carcinoma. METHODS: Thirty-nine patients (mean age 55 years, males: 32) with decompensated liver cirrhosis and refractory ascites were enrolled. All patients received a combination of tolvaptan (15 mg/d for 5-14 d) and diuretics (40-80 mg/d of furosemide and 80-160 mg/d of spironolactone). The etiology of cirrhosis included hepatitis B (69.2%), hepatitis C (7.7%) and alcohol-induced (23.1%). Changes in the urine excretion volume, abdominal circumference and edema were assessed. The serum sodium levels were also measured, and adverse events were recorded. A follow-up assessment was conducted 1 mo after treatment with tolvaptan. RESULTS: Tolvaptan increased the mean urine excretion volume (1969.2 ± 355.55 mL vs 3410.3 ± 974.1 mL, P < 0.001), and 89.7% of patients showed improvements in their ascites, 46.2% of whom showed significant improvements. The overall efficacy of tolvaptan in all patients was 89.7%; the efficacies in patients with hepatocellular carcinoma and hepatorenal syndrome were 84.2% and 77.8%, respectively. The incidence of hyponatremia was 53.8%. In patients with hyponatremia, the serum sodium levels increased after tolvaptan treatment (from 128.1 ± 4.22 mEq/L vs 133.1 ± 3.8 mEq/L, P < 0.001). Only mild drug-related adverse events, including thirst and dry mouth, were observed. CONCLUSION: Tolvaptan is a promising aquaretic for the treatment of refractory ascites in patients with decompensated liver cirrhosis. PMID:25170228

    Spontaneous bacterial peritonitis in patients with chronic hepatitis represents a very controversial matter in terms of frequency, pathology and treatment. This unusual complication mainly due to decreased immunological defences and ascitic fluid opsonic activity is not accepted by all the Authors as a rare event. However, there is agreement as far as management is concerned: cultural examination of the ascitic fluid and the relative antibiogram are the best tools in guiding the approach to an adequate antibiotic therapy.

    Refractory ascites (RA) is a challenging complication after orthotopic liver transplantation. Its treatment consists of the removal of the precipitating factors. When the etiology is unknown, supportive treatment can be attempted. In severe cases, transjugular intrahepatic portosystemic shunts, portocaval shunts, and liver retransplantation have been used with marginal results. Recently, splenic artery embolization (SAE) has been described as an effective procedure for reducing portal hyperperfusion in patients undergoing partial or whole liver transplantation. Here we describe our experience with SAE for the treatment of RA. Between June 2004 and June 2010, 6 patients underwent proximal SAE for RA. Intraoperative flow measurements, graft characteristics, embolization portal vein (PV) velocities before and after SAE, and spleen/liver volume ratios were collected and analyzed. The response to treatment was assessed with imaging (ultrasound/computed tomography) and on the basis of clinical outcomes (weight changes, diuretic requirements, and the time to ascites resolution). The PV velocity decreased significantly for each patient after the embolization (median = 66.5 cm/second before SAE and median = 27.5 cm/second after SAE, P < 0.01). All patients experienced a significant postprocedural weight loss (mean = 88.1 ± 28.4 kg before SAE and mean = 75.8 ± 28.4 kg after SAE, P < 0.01) and a dramatic decrease in their diuretic requirements. All but 1 of the patients experienced a complete resolution of ascites after a median time of 49.5 days (range = 12-295 days). No patient presented with postembolization complications. In conclusion, SAE was effective in reducing the PV velocity immediately after the procedure. Clinically, this translated into a dramatic weight loss, a reduction of diuretic use, and a resolution of ascites. SAE appears to be a safe and effective treatment for RA.

    Large-volume total paracentesis may result in paracentesis-induced circulatory dysfunction, which is associated with poor outcomes. To explore the short- and long-term effects of paracentesis-induced circulatory dysfunction on systemic hemodynamics, renal function and other cirrhosis-related complications in patients with refractory ascites, following subtotal large-volume paracentesis. Patients with cirrhosis and refractory ascites without renal dysfunction had systemic hemodynamics, renal function, and neurohormones (plasma active renin, aldosterone, norepinephrine and angiotensin II) measured pre- and 6 days post-paracentesis. Paracentesis was limited to ≤8 L with 6-8 g of albumin per liter ascites drained. Patients were followed up until transjugular intrahepatic portosystemic shunt insertion, liver transplantation, or death. Paracentesis-induced circulatory dysfunction was defined as >50 % increase in plasma active renin 6 days post-paracentesis. Fifty-seven patients (mean age 59.0 ± 9.4 years) had mean 6.8 ± 1.8 L of ascites removed with 9 ± 3 g of albumin given/L of ascites drained. Patients were followed up for 715 ± 104 days. Twenty-three patients (40.4 %) developed paracentesis-induced circulatory dysfunction with unchanged serum creatinine on day six, despite worsening of hemodynamics (mean arterial pressure 90 ± 10 mmHg at baseline vs. 84 ± 8 mmHg on day six, p < 0.05). Similar hemodynamic changes were observed among patients without paracentesis-induced circulatory dysfunction. There was no significant difference in the long-term renal function or cirrhosis-related complications between the groups. The occurrence of paracentesis-induced circulatory dysfunction, as defined by plasma active renin, may not have a significant short- and long-term impact on renal function or cirrhosis-related complications in patients with refractory ascites who undergo subtotal paracentesis with albumin infusion.

    The patient was a 67-year-old female with liver cirrhosis due to hepatitis C. She was administered furosemide at 20 mg/day and spironolactone at 25 mg/day, but the ascites did not improve. Despite the additional administration of tolvaptan at 3.75 mg/day, the response to ascites was still poor. While the dose of tolvaptan was thereafter increased to 7.5 mg/day on the 7th hospital day, the ascites still persisted. However, she continued to receive tolvaptan (7.5 mg/day) because the worsening of her subjective symptoms was mild and she wished to do so. The ascites was later found to have almost completely disappeared on computed tomography (CT) at 6 months. PMID:27853068

  12. The transjugular intrahepatic portosystemic shunt for the management of cirrhotic refractory ascites.

    Cirrhotic ascites results from sinusoidal hypertension and sodium retention, which is secondary to a decreased effective arterial blood volume. Transjugular intrahepatic portosystemic shunt (TIPS) placement is currently indicated in cirrhotic patients with refractory ascites who require large-volume paracentesis (LVP) more than two or three times per month. TIPS placement is associated with normalization of sinusoidal pressure and a significant improvement in urinary sodium excretion that correlates with suppression of plasma renin activity, which is, itself, indicative of an improvement in effective arterial blood volume. Compared with serial LVP, placement of an uncovered TIPS stent is more effective at preventing ascites from recurring; however, increased incidence of hepatic encephalopathy and shunt dysfunction rates after TIPS placement are important issues that increase its cost. Although evidence suggests that TIPS placement might result in better patient survival, this needs to be confirmed, particularly in light of the development of polytetrafluoroethylene-covered stents. Favorable results apply to centers experienced in placing the TIPS, with the aim being to decrease the portosystemic gradient to <12 mmHg but >5 mmHg. This article reviews the pathophysiologic basis for the use of a TIPS in patients with refractory ascites, the results of controlled trials comparing TIPS placement (using uncovered stents) versus LVP, and a systematic review of predictors of death after TIPS placement for refractory ascites.

    Splanchnic arterial vasodilatation and subsequent sodium and water retention play an important role in cirrhotic ascites. Midodrine and tolvaptan have been used separately in these patients. However, there are no reports on the use of combination of midodrine and tolvaptan in the control of ascites. The aim of this study was to evaluate the safety and efficacy of midodrine, tolvaptan and their combination in control of refractory or recurrent ascites in cirrhotics. Fifty cirrhotic patients with refractory or recurrent ascites were randomised to receive midodrine (n=13), tolvaptan (n=12) or both (n=13) plus standard medical therapy (SMT) or SMT alone (n=12). A significant increase in urinary volume and urinary sodium at 1 and 3 months (P<.05) was observed in all groups except SMT. There was no worsening of renal or hepatic function in any group. There was deterioration of model for end-stage liver disease (MELD) in SMT. Midodrine as well as combination of midodrine and tolvaptan but not tolvaptan alone was superior to SMT in control of ascites at 3 months (P<.05). The combination therapy was also superior to midodrine in the control of ascites at 1 month. The morbidity and mortality were similar in all the groups except SMT. The results of this pilot study suggest that midodrine and combination with tolvaptan better controls ascites without any renal or hepatic dysfunction. The combination therapy rapidly controls ascites as compared to midodrine or tolvaptan alone. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Cirrhosis is a major cause of morbidity and mortality worldwide with liver transplantations as it only possible cure. In the face of a significant organ shortage many patients die waiting. A major complication of cirrhosis is the development of portal hypertension and ascites. The management of ascites has barely evolved over the last hundred years and includes only a few milestones in our treatment approach, but has overall significantly improved patient morbidity and survival. Our mainstay to ascites management includes changes in diet, diuretics, shunt procedures, and large volume paracentesis. The understanding of the pathophysiology of cirrhosis and portal hypertension has significantly improved in the last couple of decades but the changes in ascites management have not seemed to mirror this newer knowledge. We herein review the history of ascites management and discuss some its current limitations. PMID:27729954

    The purpose of this retrospective review of the charts of 6 children who underwent surgical treatment of chylous ascites refractory to conservative measures between 1993 and 2006 was to evaluate the efficiency of fibrin glue application for control of lymph leakage. Five children had postoperative chylous ascites (neuroblastoma, 4; cystic lymphangioma, 1) and 1 had a congenital malformation. Surgical exploration revealed large areas of diffuse lymphatic leakage in all of the patients. Lymphatic fistula was not identified intraoperatively in any patient. Ingestion of lipophilic dye in a concentrated fatty meal was not helpful in locating a lymph fistula. Absorbable mesh was used in association with glue application in the last 3 patients treated. Control of ascites was achieved immediately in 2 patients and within 3 weeks in 2 patients. Repeat surgery was required in the remaining 2 patients. The mean follow-up time was 4.3 years. One patient died of tumor recurrence 12 months after surgical treatment without relapse of the ascites. Two mild late recurrences were observed at 6 and 11 months after surgery and were managed conservatively. The findings of this study show that fibrin glue application on absorbable mesh after dissection of the leakage zones is easy, safe, and effective. We recommend that surgery with glue application be repeated until control of ascites is achieved. We suggest fibrin glue application as a preventive measure against postoperative chylous ascites.

    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 with cirrhosis and refractory ascites in a tertiary unit. We performed a systematic search of literature in May 2014. In addition, 61 patients with cirrhosis and ascites were identified and followed from development of refractory ascites until death or end of follow-up. Fourteen 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. 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.

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

    Pulmonary hypertension is a common finding in patients with advanced liver disease. Similarly, among patients with advanced pulmonary arterial hypertension, right heart failure leads to congestive hepatopathy. Diuretic resistant fluid overload in both advanced pulmonary hypertension and chronic liver disease is a demanding challenge for physicians. Venous congestion and ascites-induced increased intra-abdominal pressure are essential regarding recurrent hospitalization, morbidity and mortality. Due to impaired right-ventricular function, many patients cannot tolerate extracorporeal ultrafiltration. Peritoneal dialysis, a well-established, hemodynamically tolerated treatment for outpatients may be a good alternative to control fluid status. We present a patient with pulmonary arterial hypertension and congestive hepatopathy hospitalized for over 3 months due to ascites induced refractory volume overload treated with peritoneal ultrafiltration. We report the treatment benefits on fluid balance, cardiorenal and pulmonary function, as well as its safety. In conclusion, we report a case in which peritoneal ultrafiltration was an efficient treatment option for refractory ascites in patients with congestive hepatopathy.

    The objective of this report was to evaluate the ascitic fluid of a patient with refractory lupus ascites (proband) at different time points-pre- and post-intraperitoneal treatment with dexamethasone-using a multiparametric approach which included the presence of autoantibodies and pro- and anti-inflammatory cytokines and chemokines, and a proteomic analysis. As controls, we studied two additional patients also with lupus ascites (only at basal evaluation) and two patients with ascites due to alcoholic liver cirrhosis. High levels of anti-dsDNA and anti-nucleosomes autoantibodies were detected in the ascitic fluid of all lupus patients and remained elevated in the proband throughout the follow-up. All lupus patients have detectable ascitic high levels of IL-6, IL-8, IL-10, TNF-α, MCP-1, and IGF-1 which diminished gradually in the proband after intraperitoneal dexamethasone. In the proteomic analysis of the ascitic fluid, a marked increment of apolipoprotein A1 was observed and again, it diminished gradually after intraperitoneal treatment. Our findings further support the use of intraperitoneal steroids as an effective therapeutic option for refractory ascites in systemic lupus erythematosus.

    Refractory ascites reduces the quality of life of liver cirrhosis patients. Albumin preparation and diuretics, such as furosemide, have been used to treat refractory ascites, but the effect was poor in many patients. In this study, we analyzed patients treated with tolvaptan (TLV) at our hospital and investigated predictors of the effect. The subjects were 70 patients for whom TLV was introduced to treat refractory ascites who could be analyzed between November 2013 and March 2015 at our hospital. Patient background before initiation of oral TLV treatment, the dose of diuretics, and each item of biochemical tests of blood and urine were investigated, and factors correlated with the treatment effect were analyzed. An increase of ≥1,000 ml in the daily urine volume from the day before oral treatment or a decrease of ≥1 kg in the body weight within 7 days as an early effect was observed in 33 patients and not observed in 37 patients. TLV treatment was continued for 60 days or longer in 12 of the 37 patients in whom no early effect was observed, and the presence or absence of a delayed effect and predictors of the effect were investigated. A decrease in ascites on abdominal CT with improvement of subjective symptoms at 60 days was defined as a delayed effect. When early predictors of the effect were investigated by univariate analysis, serum blood urea nitrogen (BUN) and serum creatinine (Cr) were significantly higher in the non-responder group (BUN: p = 0.03, Cr: p = 0.04), but no factor independently associated with the treatment effect was extracted on multivariate analysis. The delayed effect was noted in 4 (33.3%) of the 12 patients, but no predictor of the effect before treatment was identified. However, reactions, such as an increase in serum Na and reduction of urinary osmotic pressure, were observed early after TLV administration in some patients in whom the delayed effect was observed. The diuretic effect of TLV may decrease in renal hypofunction patients

    Ascites and abdominal pseudocysts (APC) are two rare complications that can occur following placement of a ventriculoperitoneal (VP) shunt. Both complications are characterized by abnormal intraperitoneal cerebrospinal fluid (CSF) collections. Although various factors have been implicated, the exact pathogenesis of the two conditions remains elusive. This paper presents two cases of VP shunt placement resulting from hydrocephaly. The first patient presented with generalized ascites and the other with APC, both of whom were six years old. APC and ascites after VP shunt placement are rare and distinct conditions; therefore, they may require different management strategies.

    Postoperative ascites is a very rare complication of laparoscopic surgery. Significant iatrogenic injuries to the bowel, the urinary tract, and the lymphatic system should be excluded promptly to avoid devastating results for the patient. In some cases, in spite of investigating patients extensively, no definitive causative factor for the accumulation of fluid can be identified. In such cases, idiopathic allergic or inflammatory reaction of the peritoneum may be responsible for the development of ascites. We present a case of ascites of an unknown origin in a young female patient following a laparoscopic appendicectomy. PMID:24822146

    An 86-year-old man with a long-term habit of ethanol consumption was admitted due to massive transudate ascites and leg edema. Abdominal computed tomography revealed a dilated main pancreatic duct and atrophied pancreatic parenchyma, leading to the diagnosis of chronic pancreatitis. Moreover, the portal vein was enhanced in the early arterial phase, which indicated the presence of an arterioportal fistula. The fistula was located between the posterior superior pancreaticoduodenal artery and the portal vein near a pancreatic retention cyst. Transarterial coil embolization dramatically improved the ascites. Arterioportal fistula and ensuing ascites should be recognized as a complication of chronic pancreatitis.

    We performed post-marketing surveillance to evaluate the safety and efficacy of cell-free and concentrated ascites reinfusion therapy (CART). In total, 356 CART sessions in 147 patients at 22 centers were performed. The most common primary disease was cancer (128 cases, 300 sessions). Mean amount of ascites collected was 3.7 L, and mean concentration ratio was 9.2. Mean amount of reinfused protein was 67.8 g (recovery rate, 72.0%). Performance status, dietary intake, urine volume, body weight and abdominal circumference were significantly improved after CART. Body temperature increased significantly, by 0.3°C on average. Concomitant steroids and/or NSAIDs use before reinfusion was significantly and negatively associated with increases in body temperature. Most adverse events were fever and chills. This study examined a large number of patients compared with previous studies, and showed that CART is an effective and relatively safe treatment for refractory ascites, such as malignant ascites.

    Transjugular intrahepatic portosystemic shunt (TIPS) is indicated for the treatment of refractory ascites in cirrhosis. The long-term outcome of TIPS for refractory ascites is unknown. The aim of this study is to describe the natural history of patients with refractory ascites post-TIPS, and compare between polytetrafluoroethylene (PTFE)-covered versus bare stents. A retrospective chart review of patients who had TIPS for refractory ascites was conducted. Prospectively collected data include demographics, angiographic data, blood work, and urinary sodium excretion. There were 136 patients who received TIPS (bare = 104, covered = 32) for over 22 years. Patients with PTFE stents had lower international normalized ratio and model for end-stage liver disease score. More patients with bare stents developed shunt dysfunction (74.0% vs 24.1%, P < 0.0001) and required more TIPS revisions (1.6 ± 0.2/patient vs 0.2 ± 0.1, P < 0.0001). Urinary sodium excretion increased significantly from first month and progressed to 98 ± 9 mmol/day at 12th month post-TIPS (P < 0.001 vs baseline), concurrent with improved renal function. Most patients (77.6%) completely cleared the ascites without diuretics, but many achieved this beyond 2 years. Number of TIPS revision was predictive of complete response at 12 months (odds ratio [OR] 0.7, 95% confidence interval [CI] 0.5-0.9, P < 0.05). Age (hazard ratio [HR] = 1.05 [95% CI 1.02-1.08], P < 0.01), complete response (HR = 0.22 [95% CI 0.12-0.40], P < 0.0001) and polytetrafluoroethylene stents (HR = 0.23 [95% CI 0.05-0.97], P < 0.05) were predictive of survival. TIPS is an effective treatment for cirrhotic refractory ascites. Ascites clearance is dependent on number of TIPS revision, whereas survival is predicted by younger age, complete response, and covered stent use, although era effect likely contributed to improved survival with covered stent use. © 2014 Journal of

    Introduction Patients with chronic liver diseases are usually thin as a result of hypermetabolism and malnutrition expressed by reduced levels of leptin and impairment of other adyponectins such as visfatin. Aims We evaluated the metabolic and inflammatory effects of intravenous high-dose furosemide plus hypertonic saline solutions (HSS) compared with repeated paracentesis and a standard oral diuretic schedule, in patients with cirrhosis and refractory ascites. Methods 59 consecutive cirrhotic patients with refractory ascites unresponsive to outpatient treatment. Enrolled subjects were randomized to treatment with intravenous infusion of furosemide (125–250mg⁄bid) plus small volumes of HSS from the first day after admission until 3 days before discharge (Group A, n:38), or repeated paracentesis from the first day after admission until 3 days before discharge (Group B, n: 21). Plasma levels of ANP, BNP, Leptin, visfatin, IL-1β, TNF-a, IL-6 were measured before and after the two type of treatment. Results Subjects in group A were observed to have a significant reduction of serum levels of TNF-α, IL-1β, IL-6, ANP, BNP, and visfatin, thus regarding primary efficacy endpoints, in Group A vs. Group B we observed higher Δ-TNF-α, Δ-IL-1β, Δ-IL-6, Δ-ANP, Δ-BNP, Δ-visfatin, Δ-Leptin at discharge. Discussion Our findings underline the possible inflammatory and metabolic effect of saline overload correction in treatment of cirrhosis complications such as refractory ascites, suggesting a possible role of inflammatory and metabolic-nutritional variables as severity markers in these patients.

    Objective To assess the benefit of trans-jugular intrahepatic porto-systemic shunt (TIPS) placement for refractory ascites. Design A retrospective observational study of all patients undergoing TIPS for refractory ascites in our hospital between 2003 and 2012. Setting Secondary care. Patients Cirrhotic patients with refractory ascites. Main outcome measures 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. Results 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. Conclusions TIPS is both a clinically effective and economically advantageous therapeutic option for selected patients with refractory ascites. PMID:28839725

    Patients with refractory ascites (RA) require repeated large volume paracenteses (LVP), which involves frequent hospital visits and is associated with a poor quality-of-life. This study assessed safety and efficacy of an automated, low-flow pump (alfapump® [AP]) compared with LVP standard of care [SoC]. A randomized controlled trial, in seven centers, with six month patient observation was conducted. Primary outcome was time to first LVP. Secondary outcomes included paracentesis requirement, safety, health-related quality-of-life (HRQoL), and survival. Nutrition, hemodynamics, and renal injury biomarkers were assessed in a sub-study at three months. Sixty patients were randomized and 58 were analyzed (27 AP, 31 SoC, mean age 61.9years, mean MELD 11.7). Eighteen patients were included in the sub-study. Compared with SoC, median time to first LVP was not reached after six months in the AP group, meaning a significant reduction in LVP requirement for the AP patients (AP, median not reached; SoC, 15.0days (HR 0.13; 95%CI 13.0-22.0; p<0.001), and AP patients also showed significantly improved Chronic Liver Disease Questionnaire (CLDQ) scores compared with SoC patients (p<0.05 between treatment arms). Improvements in nutritional parameters were observed for hand-grip strength (p=0.044) and body mass index (p<0.001) in the sub-study. Compared with SoC, more AP patients reported adverse events (AEs; 96.3% vs. 77.4%, p=0.057) and serious AEs (85.2 vs. 45.2%, p=0.002). AEs consisted predominantly of acute kidney injury in the immediate post-operative period, and re-intervention for pump related issues, and were treatable in most cases. Survival was similar in AP and SoC. The AP system is effective for reducing the need for paracentesis and improving HRQoL in cirrhotic patients with RA. Although the frequency of Quality of Life (and by inference hospitalizations) was significantly higher in the AP group, they were generally limited and did not impact survival. www

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

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

    The pathogenesis of refractory ascites (RA) is linked to splanchnic vasodilation. We hypothesized that a combination of midodrine, octreotide long-acting release (LAR) and albumin would result in increased natriuresis, better control of ascites and an improvement in renal function in patients with RA+/-Type 2 hepatorenal syndrome. A prospective pilot study in patients with RA as defined by the International Ascites Club. Consecutive patients received an intramuscular injection of octreotide-LAR, 50 g of albumin three times per week and midodrine titrated to increase the systolic blood pressure for 1 month. Ten patients with RA were enrolled and eight with complete data to 1 month post-treatment were included in the analysis. There was no change in renal function but there was a trend towards a reduction in the volume of ascites removed by paracentesis (P=0.08) and a significant reduction in the plasma renin (P=0.01) and aldosterone concentrations (P=0.01). Interestingly, there was a transient worsening in the model for end-stage liver disease (MELD) score (P=0.01). The deterioration in MELD was completely reversible after discontinuation of therapy. To our knowledge, this is the first study of prolonged midodrine, octreotide and albumin therapy in RA. We observed a significant reduction in the plasma renin and aldosterone concentrations and a trend towards a reduction in the volume of ascites removed by paracentesis without an effect on renal function. The beneficial effects are at the expense of a reversible deterioration in the MELD score. Large controlled trials are needed before this therapy can be routinely recommended.

    Forty four patients with refractory ascites due to chronic liver diseases that fulfilling the inclusion criteria of selection were divided into 2 groups. The first group (GI, n=24) was subdivided into 2 subgroups according to degree of liver condition; GIa (n=11) with Child-Pugh class B and GIb (n=13) with early class C. The patients were subjected to P-V shunt (Denver group). Similarly, patients in the second group (GII, n=20) were divided into 2 subgroups GIIa (n=10) & GIIb (n=10) respectively and treated by the repeated tapping and albumin infusion (control group). Postoperative results revealed a significant increase in urine out put (P<0.001), decrease in abdominal girth (P<0.01) and body weight (p<0.01) with more patients fitness and satisfaction than in controls. Postoperative complications were more in GIb. Ascites recurrence occurred in 3 (23%) patients in GIb due to severe infection (2 cases) and irreversible shunt obstruction (1 case) and without recurrence in GIa. So, Denver P-V shunt offers a good palliation in such patients, but its use is more justified in selected cases.

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

    OBJECTIVE. This single-center study evaluated the use of expanded polytetrafluoroethylene (ePTFE)-covered stent-grafts for transjugular intrahepatic portosystemic shunt (TIPS) placement to manage portal hypertension-related refractory ascites. MATERIALS AND METHODS. One hundred patients at a single tertiary care center in a major metropolitan hospital underwent TIPS placement with an ePTFE-covered stent-graft (Viatorr TIPS Endoprosthesis). Patients with portal hypertension-related ascites and preexisting hepatocellular carcinoma or liver transplant were excluded from the analysis. Records were reviewed for demographic characteristics, technical success of the TIPS procedures, and stent follow-up findings. Clinical results were assessed at 90- and 180-day intervals. RESULTS. Immediate technical success of the TIPS procedure was 100%. Of the 61 patients with documented follow-up, 55 (90.2%) had a partial or complete ascites response to TIPS creation. Of these 55 patients, nine experienced severe encephalopathy. Six of 61 patients (9.8%) did not experience a significant ascites response. Overall survival was 78.7% at 365-day follow-up. The 365-day survival was 84.2% for patients with a model for end-stage liver disease (MELD) score of less than 15, 67.0% for those with a score of 15-18, and 53.8% for those with a score of greater than 18 (p = 0.01). For patients with a MELD score of less than 18, the 365-day survival was 88.0% for those with an albumin value of 3 mg/dL or greater and 72.8% for those with an albumin value of less than 3 mg/dL (p = 0.04). CONCLUSION. TIPS placement using an ePTFE-covered stent-graft is an efficacious therapy for refractory ascites. Patients with preserved liver function-characterized by a MELD score of less than 15 or a MELD score of less than 18 and an albumin value of 3 mg/dL or greater-experience the greatest survival benefit.

    AIM: To compare the liver transplantation-free (LTF) survival rates between patients who underwent transjugular intrahepatic portosystemic shunts (TIPS) and those who underwent paracentesis by an updated meta-analysis that pools the effects of both number of deaths and time to death. METHODS: MEDLINE, EMBASE, and the Cochrane Library were searched from the inception to October 2012. LTF survival, liver transplantation, liver disease-related death, non-liver disease-related death, recurrent ascites, hepatic encephalopathy (HE) and severe HE, and hepatorenal syndrome were assessed as outcomes. LTF survival was estimated using a HR with a 95%CI. Other outcomes were estimated using OR with 95%CIs. Sensitivity analyses were performed to assess the effects of potential outliers in the studies according to the risk of bias and the study characteristics. RESULTS: Six randomized controlled trials with 390 patients were included. In comparison to paracentesis, TIPS significantly improved LTF survival (HR = 0.61, 95%CI: 0.46-0.82, P < 0.001). TIPS also significantly decreased liver disease-related death (OR = 0.62, 95%CI: 0.39-0.98, P = 0.04), recurrent ascites (OR = 0.15, 95%CI: 0.09-0.24, P < 0.001) and hepatorenal syndrome (OR = 0.32, 95%CI: 0.12-0.86, P = 0.02). However, TIPS increased the risk of HE (OR = 2.95, 95%CI: 1.87-4.66, P = 0.02) and severe HE (OR = 2.18, 95%CI: 1.27-3.76, P = 0.005). CONCLUSION: TIPS significantly improved the LTF survival of cirrhotic patients with refractory ascites and decreased the risk of recurrent ascites and hepatorenal syndrome with the cost of increased risk of HE compared with paracentesis. Further studies are warranted to validate the survival benefit of TIPS in clinical practice settings. PMID:24627607

    Ethacrynic acid is a loop diuretic little used today because of its side-effect profile and the availability of multiple alternative agents. However, in our clinical experience, ethacrynic acid can alleviate acute congestive heart failure and ascites resistant to other diuretics. Two patients aged 89 and 94 in life-threatening pulmonary edema were stabilized by ethacrynic acid after furosemide proved ineffective. A third patient, aged 83, with a pleural effusion and ascites secondary to end-stage hepatitis B and C, responded to ethacrynic acid when spironolactone and furosemide produced little urine output. Ethacrynic acid may have a unique niche as a diuretic of last resort, especially in geriatric practice.

    Objectives The aim of this article was to assess the success, safety, complication profile and factors associated with long-term patency of tunnelled peritoneal drains (PleurX) in the treatment of refractory malignant ascites. Methods Over a 4-year period, 28 consecutive patients (32 drain insertions) with refractory malignant ascites were treated with a PleurX drain. The study group comprised 7 males and 21 females (mean age, 61 years). A combination of fluoroscopic and ultrasound guidance was used to insert 4 drains; the remaining 28 drains were inserted under ultrasound guidance alone. Patient history, biochemical profiles, pathological and procedural records and clinical follow-up until death were reviewed. Statistical analysis included multivariate logistic regression analysis and Kaplan–Meier curves (p<0.05 was considered significant). Results There was a 100% technical success rate for the insertion of the drain; there were no procedure-related deaths and no major complications. Only minor complications were reported: three (10%) immediate; three (10%) early; and two (7%) late. Factors significantly associated with these complications included current chemotherapy, low haemoglobin levels, low albumin levels, high white cell count and high c-reactive protein levels. The length of time the drains remained in situ, and therefore patent, ranged from 5 to 365 days (mean, 113 days). Out of the original 28 tunnelled drains, 24 (86%) remained in situ and functioning until the patients’ death. Four (14%) drains dislodged and a subsequent PleurX drain was inserted on the opposite side of the abdominal wall. These new drains remained patent until the patient’s death. The annual event rate was 0.45 events per year. A comorbid diagnosis of renal disease or chemotherapy was significantly related to a decreased length of patency. Conclusion The use of tunnelled peritoneal drains is safe and effective and we would advocate their use as a first-line approach in

    Ascites represents the most common decompensating event in patients with liver cirrhosis. The appearance of ascites is strongly related to portal hypertension, which leads to splanchnic arterial vasodilation, reduction of the effective circulating volume, activation of endogenous vasoconstrictor systems, and avid sodium and water retention in the kidneys. Bacterial translocation further worsens hemodynamic alterations of patients with cirrhosis and ascites. The first-line treatment of uncomplicated ascites is a moderate sodium-restricted diet combined with diuretic treatment. In patients who develop refractory ascites, paracentesis plus albumin represents the most feasible option. Transjugular intrahepatic portosystemic shunt placement is a good alternative for selected patients. Other treatments such as vasoconstrictors and automated low-flow pumps are two potential options still under investigations. Ascites is associated with a high risk of developing further complications of cirrhosis such as dilutional hyponatremia, spontaneous bacterial peritonitis and/or other bacterial infections and acute kidney injury (AKI). Hepatorenal syndrome (HRS) is the most life-threatening type of AKI in patients with cirrhosis. The most appropriate medical treatment in patients with AKI-HRS is the administration of vasoconstrictors plus albumin. Finally, ascites impairs both the quality of life and survival in patients with cirrhosis. Thus, all patients with ascites should be evaluated for the eligibility for liver transplantation. The aim of this article is to review the management of patients with cirrhosis, ascites and HRS.

    Ascites is the most frequent complication of patients with cirrhosis. Ascites is related to increased renal sodium retention as a result of increased activity of the renin-angiotensin-aldosterone system in response to marked vasodilation of the splanchnic circulation. Management of uncomplicated ascites is based on a low-sodium diet and diuretics. However, approximately 10% of patients develop refractory ascites during follow-up, which is associated with a poor prognosis. The treatment of choice in patients with refractory ascites is large-volume paracentesis associated with intravenous albumin. Moreover, patients who develop refractory ascites should be considered as candidates for liver transplantation. Patients with ascites are all at risk of developing spontaneous bacterial peritonitis (SBP). SBP is a common infection in patients with cirrhosis with a risk of mortality of 20%. Empirical antibiotics are the treatment of choice in patients with SBP but differ depending on the acquisition site of infection, because nosocomial infections have a higher risk of being caused by multiresistant bacteria. In addition to antibiotic treatment, all patients with SBP should also receive intravenous albumin. This review summarizes the management of uninfected ascites and SBP in cirrhosis. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Ascites is one of the major complications of liver cirrhosis and is associated with a poor prognosis. It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis. PMID:21455322

    A young pregnant Zambian woman was referred from a district hospital in South Zambia to the university teaching hospital, Lusaka with severe anaemia and ascites. The ascites had developed over a month and the woman was currently 15 weeks pregnant. Further workup revealed that the patient was HIV-positive and the ascitic tap showed haemorrhagic fluid. After being reviewed by multiple doctors, the cause of the haemorrhagic ascites remained unclear; therefore, the decision was made to do a laparotomy. The laparotomy revealed haemoperitoneum and a large cyst attached to the liver containing 5 L of bloodstained fluid. The histopathology report revealed features consistent with a giant haemangioma. There were many barriers to accessing optimum healthcare in this case. These included limited access to blood, poor communication resulting in the patient being unaware of her HIV status and lack of patient education about HIV. 2016 BMJ Publishing Group Ltd.

    2015-01-01

    The most common complication to chronic liver failure is ascites. The formation of ascites in the cirrhotic patient is caused by a complex chain of pathophysiological events involving portal hypertension and progressive vascular dysfunction. Since ascites formation represents a hallmark in the natural history of chronic liver failure it predicts a poor outcome with a 50% mortality rate within 3 years. Patients with ascites are at high risk of developing complications such as spontaneous bacterial peritonitis, hyponatremia and progressive renal impairment. Adequate management of cirrhotic ascites and its complications betters quality of life and increases survival. This paper summarizes the pathophysiology behind cirrhotic ascites and the diagnostic approaches, as well as outlining the current treatment options. Despite improved medical treatment of ascites, liver transplantation remains the ultimate treatment and early referral of the patient to a highly specialized hepatology unit should always be considered.

    To compare the impact of covered stent-graft transjugular intrahepatic portosystemic shunt (TIPS) versus serial paracentesis on survival of patients with medically refractory ascites. In this retrospective study, cirrhotic patients who underwent covered stent-graft TIPS for refractory ascites from 2003-2013 were compared with similar patients who underwent serial paracentesis during 2009-2013. Demographic and liver disease data, Model for End-Stage Liver Disease (MELD) scores, and survival outcomes were obtained from hospital electronic medical records and the social security death index. After propensity score weighting to match study group characteristics, survival outcomes were compared using Kaplan-Meier statistics with log-rank analysis. Seventy TIPS (70% men, mean age 55.7 years, mean MELD 15.1) and 80 paracentesis (58% men, mean age 53.5 years, mean MELD 22.5) patients were compared. The TIPS haemodynamic success rate was 100% (mean portosystemic pressure gradient reduction 13 mmHg). Paracentesis patients underwent a mean of 7.9 procedures. After propensity score weighting to balance group features, TIPS patients showed a trend toward enhanced survival compared with paracentesis patients (median survival 1037 versus 262 days, p = 0.074). TIPS conferred a significant increase or trend toward improved survival compared with paracentesis at 1 (66% versus 44%, p = 0.018), 2 (56% versus 38%, p = 0.057), and 3 year (49% versus 32%, p = 0.077) time points. Thirty and 90 day mortality rates were not statistically increased by TIPS. Covered stent-graft TIPS improves intermediate- to long-term survival without significantly increasing short-term mortality of ascites patients, and suggests a greater potential role for TIPS in properly selected ascitic patients when medical management fails.

    Introduction Gorham–Stout Disease (GSD) is a rare disorder of bony destruction due to lymphangiomatosis, and is often triggered by hormones. One complication of GSD is the development of chylothorax, which carries a high mortality rate. Very little experience has been published to guide management in GSD during pregnancy to optimize both fetal and maternal health. Case Study A 20-year-old woman with known GSD presented with shortness of breath at 18 weeks of pregnancy, due to bilateral chylothoraces which required daily drainage. To minimize chylous fluid formation, she was placed on bowel rest with total parenteral nutrition (limiting lipid intake) and received octreotide to decrease splanchnic blood flow and chylous fluid drainage. Treatment options were limited due to her pregnancy. Twice daily home chest tube drainage of a single lung cavity, total parenteral nutrition, octreotide, and albumin infusions allowed successful delivery of a healthy 37 weeks' gestation infant by cesarean delivery. Discussion This case illustrates the management of a rare clinical disease of bone resorption and lymphangiomatosis complicated by bilateral, refractory chylothoraces, triggered by pregnancy, in whom treatment options are limited, and the need for a multidisciplinary health care team to ensure successful maternal and fetal outcomes.

    Clonidine is an α(2)-adrenoceptor agonist which, by coupling with G-protein, has been proposed as an alternative treatment for refractory ascites of patients with cirrhosis for several years. Genetic polymorphisms of β-adrenoceptor and angiotensin II type 1 receptor blockers have been reported to affect drug response in patients with cirrhosis. This study evaluated the clonidine-diuretic response rate, favourable predictors and genetic components of the clonidine-diuretic response in patients with cirrhosis with refractory ascites. 270 patients with cirrhosis with refractory ascites were randomised equally into two treatment groups to receive diuretics alone or the clonidine-diuretics association. The primary end point was clonidine-diuretic response rate. Secondary end points were mean daily dose of diuretics, times of paracentesis, ascites-related readmission and 1-year survival rate. Good clonidine responders had better natriuresis and diuresis as well as a significant decrease in abdominal circumference, plasma renin, aldosterone and norepinephrine levels. The overall clonidine-diuretics response rate was 55-60%. In patients with cirrhosis, the prevalence of ARDA(2)C WD/DD and GNB3 CT/TT genotypes was 71% and 77%, respectively. Among the responders, 71% of patients with cirrhosis had the ARDA(2)C WD/DD genotype and 67% has the GNB3 CT/TT genotype. Besides higher baseline norepinephrine levels, the presence of both ARDA(2)C WD/DD and GNB3 CT/TT genotypes showed a positive predictive value of 82% and a negative predictive value of 79% for good clonidine response. These results suggest that neurohormonal and genetic testing may be used as predictive factors for the additive effects of clonidine on the diuresis and natriuresis effects of diuretics in patients with cirrhosis with refractory ascites.

    We report a unique case of diabetic ketoacidosis in which a relatively low potassium level on admission was associated with consequent life-threatening and refractory arrhythmia secondary to inappropriate use of intravenous insulin and bicarbonate therapy. The latter was reversed by rapid bolus potassium injection. Although we do not advocate this approach in every case, we emphasise that a bolus injection of potassium may be life saving in such cases. The lessons from this case have led to multidisciplinary meetings and modification of the institute's diabetic ketoacidosis clinical pathway.

    Ascites and renal dysfunction are frequent complications experienced by patients with cirrhosis of the liver. Ascites is the pathologic accumulation of fluid in the peritoneal cavity, and is one of the cardinal signs of portal hypertension. The diagnostic evaluation of ascites involves assessment of its granulocyte count and protein concentration to exclude complications such as infection or malignoma and to allow risk stratification for the development of spontaneous peritonitis. Although sodium restriction and diuretics remain the cornerstone of the management of ascites, many patients require additional therapy when they become refractory to this treatment. In this situation, the treatment of choice is repeated large-volume paracentesis. Alteration in splanchnic hemodynamics is one of the most important changes underlying the development of ascites. Further splanchnic dilation leads to changes in systemic hemodynamics, activating vasopressor agents and leading to decreased renal perfusion. Small alterations in renal function influence the prognosis, which depends on the cause of renal failure. Prerenal failure is evident in about 70% of patients, whereas in about 30% of patients the cause is hepatorenal syndrome (HRS), which is associated with a worse prognosis. Therefore, effective therapy is of great clinical importance. Recent data indicate that use of the new definition of acute kidney injury facilitates the identification and treatment of patients with renal insufficiency more rapidly than use of the current criteria for HRS. In this review article, we evaluate approaches to the management of patients with ascites and HRS. PMID:25729433

    Refractory coeliac disease, enteropathy associated T-cell lymphoma and small bowel adenocarcinoma are rare but prognostically important complications in coeliac disease. To analyse potential changes in occurrence of complicated coeliac disease over the last 25 years. One thousand one hundred and thirty eight patients were included and evaluated based on their time of first presentation at the Medical University of Vienna, Austria. Occurrences of refractory coeliac disease and associated malignancies were evaluated for 5-year intervals from January 1990 until December 2014 and were compared over time. 2.6% (n = 29) were diagnosed with refractory coeliac disease (females 65.6%, mean age at diagnosis 62.8 years). The proportion of those patients was 2.6%, 3.1%, 3.3%, 2.7% and 0.5% for the 5 year intervals from 1990 onwards. Thus, the number of refractory cases has been decreasing since 2000 (P = 0.024). The number of patients presenting with lymphoma (n = 7) was 0.6%, 0.4%, 1.1%, 0.8% and 0% from 1990 to 2014. Similarly the number of patients with adenocarcinoma (n = 4) decreased to 0% until 2014. Overall mortality in patients suffering from refractory disease was 48%. Of all patients diagnosed with lymphoma 71.4% died with a 5-year survival rate of 28.6%. Over the past 15 years the occurrence of complicated coeliac disease has been decreasing. This possibly reflects a higher awareness of coeliac disease and optimised diagnosis and treatment with avoidance of long-term immunological disease activity. Symptomatic disease and a delay in diagnosis are risk factors for refractory coeliac disease and related cancer. © 2016 John Wiley & Sons Ltd.

    Chylous ascites and high-output chylous fistula are rare complications following abdominal or pelvic surgery. We report a series of five cases that occurred after pelvic lymph node dissection for urological cancer, in addition to their clinical presentation, diagnosis, and treatment. The series comprises five patients; four men in whom robotic radical prostatectomy and extended pelvic lymphadenectomy were performed, and one woman with an infiltrating bladder cancer that underwent robotic anterior pelvic exenteration and extended pelvic lymphadenectomy. The first four patients developed chylous ascites, and the female patient a high-output chylous fistula. In all cases, diagnosis of chylous ascites or chylous fistula was confirmed, and they were handled in varied ways, from observation to medical treatment, paracentesis, and surgery, according to their clinical presentation and evolution. We describe a simple treatment algorithm. This rare surgical complication requires a grade of suspicion and a defined treatment according to the probability of the medical compromise. Prevention is an important element. This series, according to our knowledge, is the first description in patients undergoing robotic extended pelvic lymphadenectomy.

    Background: Refractory status epilepticus is often treated with third-line therapy, such as pentobarbital coma. However, its use is limited by side effects. Recognizing and preventing major and minor adverse effects of prolonged pentobarbital coma may increase good outcomes. This study retrospectively reviewed direct and indirect medical and surgical pentobarbital coma. Methods: Retrospective chart review of all patients with refractory status epilepticus treated with pentobarbital over a 1 year period at a large tertiary care center. We collected baseline data, EEG data, and complications that were observed. Results: Overall, nine patients [median age 46.4 (IQR 21.7, 75.5) years] were induced with pentobarbital coma median 11 (IQR 3, 33) days after seizure onset for a median of 9 (IQR 3.5, 45.4) days. A total of four to eight concurrent antiepileptics were tried prior to the pentobarbital coma. Phenobarbital, due to recurrence of seizures on weaning pentobarbital coma, was required in seven patients. Observed complications included peripheral neuropathy (77.8%), cerebral atrophy (33.3%), volume overload (44.4%), renal/metabolic (77.8%), gastrointestinal (66.6%), endocrine (55.6%), cardiac/hemodynamic/vascular (77.8%), respiratory (100%), and infectious (77.8%). The number of complications trended with duration of induced coma but was nonsignificant. Median ICU length of stay was 40 (IQR 28, 97.5) days. Overall, five patients were able to follow commands after a median 37 (IQR 25.5, 90) days from coma onset. There were eight patients that were discharged from hospital with three remaining in a prolonged unresponsive state. There was one patient that died prior to discharge. Conclusions: This study highlights the high morbidity in patients with refractory status epilepticus requiring pentobarbital coma. Anticipating and addressing the indirect and direct complications in prolonged pentobarbital coma may improve survival and functional outcomes in patients with

    Ulcerative colitis can be complicated by the development of leukocytoclastic vasculitis, a cutaneous vasculitis with the potential for systemic involvement. We present a man with a history of ulcerative colitis complicated by end-stage liver disease secondary to sclerosing cholangitis requiring a liver transplant. The patient developed new-onset vasculitis and diarrhea refractory to therapy with standard immunosuppression. He was treated with anti-CD20 therapy with a positive response. The basis of the vasculitis was likely one related to an underlying monoclonal paraprotein with cryoprecitable properties. Treatment with anti-B-cell therapy may be a new treatment option for patients with gammopathy-associated leukocytoclastic vasculitis.

    There are currently no published data on post-paracentesis circulatory dysfunction (PPCD) or its prevention in children. Our study was aimed to analyze the safety and complications of large volume paracentesis (LVP) in children with severe ascites due to chronic liver disease with or without albumin therapy. A prospective longitudinal observational study enrolled children with severe ascites who underwent single time LVP at admission. They were divided into albumin infused (AI) and albumin non-infused (ANI) groups. Hemodynamic monitoring and laboratory parameters including plasma renin activity (PRA) were compared between baseline, 48 h and day 6 of LVP. Their outcome at 3 months and maximal follow-up were noted. 32 children (AI, n=17; ANI, n=15) had comparable baseline characteristics and 90.6% had high PRA at onset. The incidence of PPCD was 37.5% (ANI: 67%; AI: 12%, p=0.003), occurred if ascitic fluid extraction was >197.5 ml/kg (sensitivity: 90%; specificity: 50%, p=0.01) and if flow rate was higher in ANI group (1224 ± 476 vs. 678 ± 214 ml/h, p=0.009). ANI patients were susceptible to asymptomatic, persistent hyponatremia (baseline vs. day 6, 131 ± 4 vs. 128 ± 6 mEq/L; p=0.04) and had higher rates of recurrent ascites (42%) and hospital readmission (67%) within 3 months. No survival benefit among the AI or non-PPCD groups was demonstrated. LVP is safe in all age groups, best performed under albumin cover to overcome the problems of PPCD and hyponatremia. It is prudent to restrict volume extraction to less than 200 ml/kg actual dry weight for all and flow rate of 680 ml/h in ANI. Copyright © 2015 European Association for the Study of the Liver.

    Recent data have suggested that non-selective β-blockers (NSBB) are associated with increased mortality in patients with cirrhosis and refractory ascites. However, other evidence implies that NSBB may be beneficial in this setting by reducing bacterial translocation. Our aim was to determine whether NSBB use was a risk factor for mortality in patients with end-stage chronic liver disease and ascites awaiting liver transplantation. This was a single-centre retrospective study of 322 patients with ascites listed January 2007 to July 2011. NSBB patients (n=159) and non-NSBB patients (n=163) were comparable with regards to listing model for end-stage liver disease score (p=0.168), frequency of hepatocellular carcinoma (p=0.193) and refractory ascites (35.2% vs. 37.4%, p=0.681). 82 patients died, 221 patients were transplanted and 19 patients were removed from the list during a median follow-up duration of 72 days; the median time to death was 150 and 54 days in the NSBB and non-NSBB groups, respectively. In a multivariate competing risk Cox model, patients on NSBB had reduced mortality compared with propensity risk score-matched non-NSBB patients (HR 0.55; 95% CI 0.32 to 0.95, p=0.032). Similarly, in the subgroup of patients with refractory ascites (n=117), NSBB remained independently associated with less waitlist death (adjusted HR 0.35; 95% CI 0.14 to 0.86, p=0.022). NSBB in patients with ascites and refractory ascites listed for liver transplantation are not detrimental, and instead are associated with reduced waitlist death. Our findings argue that NSBB are safe and may confer benefit in patients with ascites complicating end-stage liver disease. Published by the BMJ Publishing Group Limited.

  2. CART: Cell-free and Concentrated Ascites Reinfusion Therapy against malignancy-related ascites.

    PubMed

    2017-08-30

    A standard strategy against ascites, a common symptom observed in cirrhotic and cancer patients, includes restriction of sodium intake and use of a diuretic. Paracentesis is a widely applied method against refractory ascites that do not react to such treatment. However, emerging fatigue and hemodynamic instability are possibly attributable to a loss of protein included in ascites. Cell-free and Concentrated Ascites Reinfusion Therapy (CART) is also applied against refractory ascites. CART comprises three processes. After ascites is first filtered to remove cell components, it is concentrated to reduce its volume. Fluid obtained through these processes, including useful proteins such as albumin and globulin, is finally reinfused intravenously. CART was reported first in the 1970s. Since then, it has been applied mainly against cirrhotic ascites with a thinner cell component. Now, its indication is expanding to include malignancy-related ascites. Additionally, CART can be applied safely against malignancy-related ascites. Its favorable effects on control of patients' symptoms are anticipated, especially on fatigue. Although related evidence has not been established, CART can be anticipated for use as a strategy against refractory ascites. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Piano, Salvatore; Tonon, Marta; Angeli, Paolo

    2016-07-01

    Ascites is the most common complication of cirrhosis. Ascites develops as a consequence of an abnormal splanchnic vasodilation with reduction of effecting circulating volume and activation of endogenous vasoconstrictors system causing salt and water retention. Patients with ascites have a high risk to develop further complications of cirrhosis such as hyponatremia, spontaneous bacterial peritonitis and acute kidney injury resulting in a poor survival. In recent years, new studies helped a better understanding of the pathophysiology of ascites and acute kidney injury in cirrhosis. Furthermore, new diagnostic criteria have been proposed for acute kidney injury and hepatorenal syndrome and a new algorithm for their management has been recommended with the aim of an early diagnosis and treatment. Herein we will review the current knowledge on the pathophysiology, diagnosis and treatment of ascites and acute kidney injury in patients with cirrhosis and we will identify the unmet needs that should be clarified in the next years.

    Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings. PMID:26339267

The mean maximum pentobarbital infusion dosage was 5.2 ± 1.8 mg/kg/h. Twenty-five patients received a continuous midazolam infusion with an average dosage of 0.41 ± 0.43 mg/kg/h. The median length of stay was longer for the pentobarbital group. Children requiring pentobarbital therapy were more likely to develop hypotension, require inotropic support, need intubation, mechanical ventilation, peripheral nutrition, and blood products; furthermore, they were more likely to develop hypertension and movement disorder after or during weaning. In conclusion, children with RSE who required pentobarbital therapy had a longer hospital stay with more complications.

    Abstract Rationale: Myocarditis is a rare but potentially fatal complication of Still's disease (about 7% of total cases). Patient concerns: A 42-year-old woman was admitted to our ward with high-grade fever, rash and polyarthralgia, lasting since 4 weeks and rapidly complicated by MAS and acute heart failure. Diagnoses: Adult Onset Still's Disease rapidly developping macrophage activation syndrome and disseminated intravascular coagulopathy, further complicated by iperacute myocarditis with cardiac arrest. Interventions: After failure of conventional therapies (steroids plus cyclosporine and then biological therapy with Anakinra 100 mg/day), the patient was treated with anakinra 100 mg sc 1 fl 4 times a day. Outcomes: Fast clinical and laboratoristic improvement and subsequent disease remission with complete recovery of cardiac function. Lessons: This is the first case report in which high doses of Anakinra have been used to treat a refractory AOSD complicated by MAS and myocarditis. In AOSD complicated by life-threatening conditions, probably we need to consider aggressive therapeutic approaches with higher doses of Il-1 receptor blocker to switch off the hyper-inflammation.

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

  8. Pathogenesis of ascites and predictors of resistance to therapy.

    Ascites is one of the most frequent complications of cirrhosis. Its appearance is considered as the marker of the transition from the compensated to the decompensated stage of the disease. Appearance of ascites also has prognostic significance, as it causes a sharp drop in the expected survival rate. Portal hypertension is a sine qua-non for the development of ascites. Although no precise portal pressure threshold has been defined for the development of ascites, the latter rarely develops with portal pressures below 12 mmHg. In addition, in patients treated with interventions that markedly decrease portal pressure, such as surgical porta-caval shunts or transjugular intrahepatic portalsystemic shunts, a disappearance or a marked reduction of ascites can be observed. The currently most accepted theory of ascites formation is the so-called 'forward' theory. According to this theory, the development of ascites is related to the presence of severe sinusoidal portal hypertension, which causes marked splanchnic arterial vasodilation and a forward increase in the splanchnic production of lymph. Splanchnic arterial vasodilation also causes a significant reduction of the effective blood volume, leading to activation of sodium and water-retaining mechanisms. The retained sodium and water, however, while increasing total plasma volume, are unable to compensate for the reduced effective blood volume, initiating a vicious cycle. In the advanced stages of cirrhosis, the extreme underfilling of the arterial circulation leads to a maximal stimulation of the vasoconstrictor mechanisms which override the protective effect of renal vasodilator factors and cause renal vasoconstriction, further aggravating ascites and leading to functional renal insufficiency. Renal insufficiency is also one of the main causes of resistance to diuretic therapy. While several studies have investigated the predictors of survival in cirrhotic patients with ascites, this has not been done for the

    Abstract Background: Plasmacytoid urothelial carcinoma (PUC) is a distinct variant of urinary bladder cancer, with a high propensity for invasion and poor prognosis. These tumors occur most commonly in male patients with the age of reported cases ranging from 46 to 87 years. Case report: We present a case of a 74-year-old male patient having massive ascites and bilateral lower leg edema. Colonoscopy showed a 3-cm lesion in the sigmoid colon and an edematous nonpapillary tumor was found by cystoscopy in the bladder. Histopathology analysis of the biopsies showed adenocarcinoma of colon and PUC of bladder. The diagnosis of PUC with peritoneal carcinomatosis was then confirmed by immunohistochemical stain. Conclusion: The diagnostic dilemmas of the unusual variant of urothelial malignancy, the origin of peritoneal metastasis, and its clinical impact are discussed in the present case. PMID:28207504

    A six-year-old Rottweiler with chronic ascites and moderate panhypoproteinaemia that had been treated with large volume paracentesis over several months duration was diagnosed with a large bi-atrial mass and hepatic fibrosis. For palliative treatment, a peritoneo-vesical automated fluid shunt system with an integrated chargeable battery and an integrated computer to control pump function and to transmit data transcutaneously was implanted by coeliotomy. The pump was left in place for 10 weeks, eliminating the need for further paracentesis during this time. At the end of this period, no ascites was discernible and serum protein concentrations had returned to their respective reference intervals. As a complication, decubitus with skin perforation had developed above the pump. Besides palliative treatment of chronic refractory ascites, this pump may have application in other conditions characterised by chronic cavity effusion or in peritoneal dialysis.

    The use of midazolam for the treatment of status epilepticus in children has generally been shown to be well tolerated and safe. Furthermore, encouraging efficacy has been observed when pediatric patients with status epilepticus have received continuous intravenous infusions of midazolam. A 9-year-old girl was treated with high-dose, continuous intravenous infusion of midazolam for the management of refractory status epilepticus. The patient developed a severe hyperchloremic, non-anion gap metabolic acidosis and resultant hemodynamic compromise, necessitating significant inotropic support and the initiation of a vasopressor infusion. We speculate that this complication was due to the preparation of parenteral midazolam with hydrochloric acid. The midazolam infusion was stopped, and, in less than 5 hours, the patient's metabolic acidosis resolved. The patient's inotropic and vasopressor infusions could only be weaned after discontinuing the use of high-dose midazolam. Although this complication was observed in only 1 pediatric patient with cortical dysplasia, caution and close clinical and laboratory surveillance should be exercised when administering continuous intravenous infusions of midazolam to pediatric patients.

    Ascites is a pathologic accumulation of peritoneal fluidcommonly observed in decompensated cirrhotic states.Its causes are multi-factorial, but principally involve significant volume and hormonal dysregulation in the setting of portal hypertension. The diagnosis of ascites is considered in cirrhotic patients given a constellation of clinical and laboratory findings, and ultimately confirmed, with insight into etiology, by imaging and paracentesis procedures. Treatment for ascites is multi-modal including dietary sodium restriction, pharmacologic therapies, diagnostic and therapeutic paracentesis, and in certain cases transjugular intra-hepatic portosystemic shunt. Ascites is associated with numerous complications including spontaneous bacterial peritonitis, hepato-hydrothorax and hepatorenal syndrome. Given the complex nature of ascites and associatedcomplications, it is not surprising that it heralds increased morbidity and mortality in cirrhotic patients and increased cost-utilization upon the health-care system. This review will detail the pathophysiology of cirrhotic ascites, common complications derived from it, and pertinent treatment modalities. PMID:23717736

    Cirrhosis is the final stage of most of the chronic liver diseases and is most invariably complicated by portal hypertension resulting in ascites. A case of chronic liver disease with portal hypertension (cryptogenic cirrhosis), managed at Amrita School of Ayurveda is discussed in this paper. The clinical picture was that of an uncomplicated cirrhotic ascites. Snehapāna (therapeutic oral administration of lipids) followed by virecana (purgation) was done after an initial course of nityavirecana (daily purgation). Later Vardhamāna pippalī rasāyana [administration of single drug - pippalī (piper longum) in a structured dose pattern] was administered with an intention of rejuvenating liver cells. Ascites and lower limb oedema were completely resolved after the therapy. No recurrence of ascites has been reported after a follow up period of one year. PMID:27621523

    Novel cell-free and concentrated ascites reinfusion therapy (KM-CART) is easy to use, safe and applicable for refractory ascites. We can get the full amount of ascites, filtrate, and concentrate in a short time. KM-CART can be applied as palliative care for dying patients including patients with massive malignant ascites. Some patients who underwent repeated KM-CART survived longer than those who did not repeat the therapy. The aim of this study was to identify the type of patients with ascites for whom KM-CART would be effective and candidates for repeated KM-CART. In this retrospective cohort observational study, we examined 123 CART processes performed on 58 patients with refractory ascites. Data were collected before and after processing of the ascites. We compared two groups; patients who underwent KM-CART ≥ 5 times and those who underwent this process ≤ 4 times. Age, disease, benign or malignant status of the disease, the amount of ascites, concentrations of total protein (TP) and albumin (Alb) and their amounts in the original ascites and the filtered and concentrated ascitic fluid and the recovery ratio of TP and Alb were determined. No significant difference was observed between the two groups in age, disease, amount of ascites, and the recovery ratio of TP and Alb. Significant differences were observed in the amounts of TP and Alb in the original ascites and the filtered and concentrated ascitic fluid. Patients who underwent KM-CART ≥ 5 times had higher Alb levels in the original ascites than those who underwent this therapy ≤ 4 times. Patients with higher Alb concentrations in the original ascites could be candidates for repeated KM-CART. © 2015 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

  16. Translating Our Current Understanding of Ascites Management into New Therapies for Patients with Cirrhosis and Fluid Retention.

    Ascites is the most common complication associated with cirrhosis resulting in poor quality of life, high risk of development of other complications of cirrhosis, increased morbidity and mortality associated with surgical interventions, and poor long-term outcome. Patients with cirrhosis and a first onset of ascites, have a probability of survival of 85% during the first year and 56% at 5 years without liver transplantation. Ascites is caused due to increased renal sodium retention as a result of increased activity of the renin-angiotensin-aldosterone system in response to marked vasodilation of the splanchnic circulation. The practical management of ascites involves the proper evaluation of a patient with a thorough history and physical exam. In addition, complete laboratory, ascitic fluid, and radiological tests should be performed. One of the most important steps in the initial assessment of patients with ascites is to refer the appropriate candidates for liver transplantation, as it offers a definitive cure for cirrhosis and its complications. While the initial management of uncomplicated ascites with low sodium diet and diuretic treatment is straightforward in a majority of patients, approximately 10% of patients fail to respond to diuretics and become a real therapeutic challenge. The initial treatment of choice in patients with refractory ascites is large-volume paracentesis (LVP) associated with intravenous albumin; some patients also benefit from transjugular intrahepatic portosystemic shunts (TIPS). When repeated LVP or TIPS cannot be performed, other approaches using vasoconstrictors such as midodrine can be considered although data are scarce. A newly designed automated low flow pump system (Alfapump), which is designed to move ascites from the peritoneal cavity to the urinary bladder where it is eliminated spontaneously through diuresis is promising, but the data are also limited and safety is still a matter of concern.

    BACKGROUND: Ascites is defined as the pathological accumulation of fluid in the peritoneal cavity. It is the most common complication of cirrhosis, which is also the most common cause of ascites. Viscosity is a measure of the resistance of a fluid to deform under shear stress. Plasma viscosity is influenced by the concentration of plasma proteins and lipoproteins, with the major contribution from fibrinogen. To our knowledge, the viscosity of ascitic fluid has not yet been studied. OBJECTIVE: To evaluate the role of ascitic fluid viscosity in discriminating between ascites due to portal hypertension-related and nonportal hypertension-related causes, and to compare results with the serum-ascites albumin gradient (SAAG). METHODS: The present study involved 142 patients with ascites presenting with diverse medical problems. Serum total protein, albumin, glucose, lactate dehydrogenase (LDH) levels and complete blood count were obtained for all subjects. Paracentesis was performed routinely on admission and all ascitic fluid samples were evaluated by manual cell count with differential, ascitic fluid culture and biochemistry (total protein, albumin, glucose and LDH). Cultures of ascitic fluid were performed at bedside in all patients using blood culture bottles. Ascitic fluid viscosity was measured in a commercially available cone and plate viscometer. RESULTS: Of the 142 patients studied, 34 (24%) had an SAAG of 11 g/L or less, whereas 108 (76%) had an SAAG of greater than 11 g/L. Sex and mean age did not differ significantly between the two groups (P>0.05). Serum total protein, albumin, glucose, LDH levels, leukocyte count, ascitic fluid glucose levels and ascitic fluid leukocyte counts were similar in both groups, with no statistically significant relationship detected (P>0.05). However, the mean (±SD) ascitic fluid total protein (0.0172±0.1104 g/L versus 0.043±0.011 g/L), albumin (0.0104±0.0064 g/L versus 0.0276±0.0069 g/L) and LDH (102.76±80.95 U/L versus 885

    Chylous ascites is a rare complication of abdominal surgery in children. Particularly, reports of postoperative chylous ascites are rare. This report describes the very rare case of a 10-month-old girl complicated by chylous ascites after resection of a choledochal cyst with a Roux-en-Y hepaticojejunostomy, who was successfully treated medically. To date, we have found a few cases of postoperative chylous ascites in the paediatric literature. To the best of our knowledge, this is the first report of chylous ascites after the resection of a choledochal cyst in a child who was successfully treated solely by no fasting. No fasting might be a therapeutic option of paediatric postoperative chylous ascites after the resection of a choledochal cyst if the outflow volume of chylous ascites is small.

    Factors predictive of skeletal-related events (SREs) in bone metastatic prostate cancer patients with hormone-refractory disease were investigated. We evaluated the frequency of SREs in 200 hormone-refractory patients consecutively observed at our Institution and followed until death or the last follow-up. Baseline parameters were evaluated in univariate and multivariate analysis as potential predictive factors of SREs. Skeletal-related events were observed in 86 patients (43.0%), 10 of which (5.0%) occurred before the onset of hormone-refractory disease. In univariate analysis, patient performance status (P=0.002), disease extent (DE) in bone (P=0.0001), bone pain (P=0.0001), serum alkaline phosphatase (P=0.0001) and urinary N-telopeptide of type one collagen (P=0.0001) directly correlated with a greater risk to develop SREs, whereas Gleason score at diagnosis, serum PSA, Hb, serum albumin, serum calcium, types of bone lesions and duration of androgen deprivation therapy did not. Both DE in bone (hazard ratio (HR): 1.16, 95% confidence interval (CI): 1.07–1.25, P=0.000) and pain score (HR: 1.13, 95% CI: 1.06–1.20, P=0.000) were independent variables predicting for the onset of SREs in multivariate analysis. In patients with heavy tumour load in bone and great bone pain, the percentage of SREs was almost twice as high as (26 vs 52%, P<0.02) and occurred significantly earlier (P=0.000) than SREs in patients with limited DE in bone and low pain. Bone pain and DE in bone independently predict the occurrence of SREs in bone metastatic prostate cancer patients with hormone-refractory disease. These findings could help physicians in tailoring the skeletal follow-up most appropriate to individual patients and may prove useful for stratifying patients enrolled in bisphosphonate clinical trials.

    Transjugular intrahepatic portosystemic shunt (TIPS) has evolved as an effective intervention for treatment of complications of portal hypertension. The use of polytetrafluoroethylene-covered stents have improved the patency of the shunts and diminished the incidence of TIPS dysfunction. However, TIPS-related refractory hepatic encephalopathy (rHE) poses a significant challenge. Approximately 3-7 % of patients with TIPS develop rHE. Refractory hepatic encephalopathy is defined as a recurrent or persistent encephalopathy despite appropriate medical treatment. Hepatic encephalopathy can be an extremely debilitating complication that profoundly affects quality of life. The approach to management of patients with rHE is complex and typically requires collaboration between different specialties. Liver transplantation is the ultimate treatment for rHE; however, the ongoing shortage of organ donation markedly limits this treatment option. Alternative therapies such as shunt occlusion or reduction can control symptoms and serve as a 'bridge' therapy to liver transplantation. Therefore, interventional radiologists play a key role in the management of these patients by offering a variety of endovascular techniques. The purpose of this review is to highlight some of these endovascular techniques and to develop a therapeutic algorithm that can be applied in clinical practice for the management of rHE.

    In 1997, the US Food and Drug Administration approved the use of intermittent stimulation of the left vagal nerve as adjunctive therapy for seizure control. Vagal nerve stimulation (VNS) has since been considered a safe and effective treatment for medically intractable seizures. The objective of this study is to present our experience with the surgical procedure and outcomes after VNS insertion in the first 100 consecutive patients treated at the Tel-Aviv "Sourasky" Medical Center (TASMC). All patients who underwent VNS device implantation by the authors at TASMC between 2005 and 2011 were studied. The collected data included age at onset of epilepsy, seizure type, duration of epilepsy, age at VNS device implantation, seizure reduction, surgical complications, and adverse effects of VNS over time. Fifty-three males and 47 females, age 21.2 ± 11.1 years, underwent VNS implantation. Indications for surgery were medically refractory epilepsy. The most common seizure type was focal (55 patients, 55 %). Seizure duration until implantation was 14.4 ± 9 years. Mean follow-up time after device insertion was 24.5 ± 22 months. Complications were encountered in 12 patients. The most common complication was local infection (6 patients, 6 %). Six devices were removed-four due to infection and two due to loss of clinical effect. Currently, 63 patients remain in active long-term follow-up; of these, 35 patients have >50 % reduction in frequency of attacks.VNS is a well-tolerated and effective therapeutic alternative in the management of medically refractory epilepsy. The surgical procedure is safe and has a low complication rate.

    Spontaneous ascites infection is a frequently encountered and important complication of decompensated liver cirrhosis. The immune system plays an important role in the development or eradication of this infection. A number of compositional and functional alterations in immune system cells have been demonstrated in cirrhotic patients; however, there is a lack of knowledge about this issue in ascitic infections. The aim of the present study was to evaluate lymphocyte subsets and levels of some ascitic and lymphocytic intracytoplasmic cytokines in decompensated cirrhotic patients with or without spontaneous ascites infection. The study population consisted of 45 decompensated cirrhotic patients (32 men, 13 women) with different etiologies. Patients with ascitic polymorphonuclear leukocyte count > or =250/mm(3) and/or positive ascitic bacterial cultures were classified as the "infected group". Comparison was made between the infected and non-infected group for the following parameters: ascites leukocyte counts and differentiations; ascitic fluid protein; albumin levels and serum-ascites albumin gradients; flow cytometric detection of cell surface markers for ascitic T, B and natural killer lymphocytes; intracytoplasmic interleukin (IL)-2, IL-4, tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma; levels of ascitic IL-8, IL-10, IL-12 and TNF-alpha; and soluble Fas antigen and soluble Fas ligand. The CD4/CD8 ratio was significantly decreased and expression of T cell receptor-gammadelta was increased in the infected group. Furthermore, ascites TNF-alpha levels were also elevated in this group. Ascitic IL-8, IL-10, IL-12 and TNF-alpha levels were significantly higher in patients with positive ascitic bacterial culture. These results suggest that a cytotoxic, especially Th1, immune response predominates in ascites infections. It also demonstrates that TNF-alpha might be involved in the pathogenesis of ascites infections.

There were no major complications, and the only procedure-related complications occurred in two patients who had mild, treatable hepatic encephalopathy. All patients had improvement as defined by decreased need for thoracentesis or paracentesis, with postprocedure follow-up ranging from 19 to 491 days.ConclusionTIPS is a safe procedure that is effective in the treatment of cirrhosis-related chylous collections.

    Epistaxis generally responds to conservative management, but a more invasive approach, such as superselective embolization, is sometimes justified. We report our experience with endovascular procedures in 19 patients from 2002 to 2011 for the treatment of refractory idiopatic posterior epistaxis. The sphenopalatine artery and distal internal maxillary arteries were embolized in all patients. Unilateral embolization was performed in 12 patients (63%), bilateral embolization in seven (37%). Additional embolization of the descending palatine artery was performed in eight patients (42%) and embolization of the facial artery and palatine arteries in four (21%). In one patient the distal ophthalmic artery was embolized with n-butyl cyanoacrylate. No minor or major complications occurred in relation to the embolization procedures. The average hospital stay was 11.1±8.6 days, including an average 5.2±3.4 days after embolization. Average follow-up after discharge was 21.3±25.7 months. Superselective endovascular embolization proved safe and effective in controlling idiopathic epistaxis, refractory to other maneuvers. Copyright © 2011 Elsevier Ltd. All rights reserved.

Retrospective review of all transhepatic PCTs placed between January 2005 and June 2014 was performed: 255 patients were included (median age of 65 y; range, 20-95 y). Of these patients, 97 had ascites and 158 had no ascites or only pelvic fluid. In all, 115 patients had calculous cholecystitis (45%), 127 had acalculous cholecystitis (50%), and 13 had common bile duct obstruction (5%). The primary outcome of interest was all complications, including bile peritonitis, pericatheter leakage requiring PCT change, pericholecystic abscess formation, drain dislodgment, or death from biliary sepsis within 14 days of initial PCT insertion. The overall complication rate was 11% among patients with ascites (n = 11), compared with 10% in those without (n = 16; P = .834). No difference was found between the two groups in any one complication. The overall outcome of PCT drainage differed between groups, with significantly shorter survival times in patients with ascites. Patients with ascites underwent cholecystectomy less often than patients without ascites (21% vs 39%; P = .002). Likewise, patients with ascites were more likely than those without ascites to die with the PCT in place (49% vs 25%; P = .001). Frequencies of complications following PCT insertion were similar in patients with and without ascites. Additionally, the overall complication rate was low and not significantly different between the two groups. These observations support the use of PCT placement in patients with ascites.

    Breath-holding spells (BHS) are benign non-epileptic paroxysmal events of infancy, rarely occurring with high frequency and complicated by prolonged syncope, convulsions and even status epilepticus. In these cases response to medical treatment is often unsatisfactory. Pacemaker implantation is a possible therapeutic option, but its indications, efficacy and complications have not been clarified yet. To report a new case of BHS treated with pacemaker and to review its indications and efficacy in patients with severe BHS. We extensively searched the literature in PubMed on cardiac pacing in patients with BHS and we described a new case. A previously healthy boy presented at the age of 4 months with frequent BHS inconstantly associated to prolonged syncope and post-anoxic non-epileptic and epileptic seizures. Parental reassurance, iron supplementation and piracetam were ineffective. After cardiac pacing at the age of 16 months, BHS and their complications disappeared. We identified 47 patients with BHS treated with pacemaker in the literature. Based on the available data, in all patients asystole or marked bradycardia were documented during BHS or stimulating maneuvers; syncope complicated BHS in 100% of cases and post-anoxic convulsions in 78.3%. Medical treatment before pacing, when administered, was ineffective or poorly tolerated. After pacing, BHS complications disappeared in 86.4% of cases, and decreased in 13.6%. Technical problems with the device were reported in 25.7% of patients and mild medical complications in 11.4%. Pacemaker could be reasonably considered in subjects with frequent and severe BHS, poor response to medications, and demonstration of cardioinhibition during spells.

    A 46-year-old man underwent living-donor liver transplantation and splenectomy for primary biliary cirrhosis. On postoperative day 22, cloudiness of ascites increased, and triglyceride concentration in ascites was as high as 1046 mg/dL. With a diagnosis of chylous ascites, total parenteral nutrition was started. Nine days after starting total parenteral nutrition, cloudiness of ascites decreased, and triglycerides in ascites decreased to 93 mg/dL. Oral intake was restarted, and the patient was discharged on postoperative day 46. Chylous ascites is a rare complication after living-donor liver transplantation for which total parenteral nutrition may be useful. PMID:23294080

    Spontaneous fungal peritonitis (SFP) is an infrequent but severe complication most commonly described in patients with liver cirrhosis. We present the first case of culture-proven SFP occurring in cardiogenic ascites. The diagnosis of SFP was clinically challenging as the initial ascites was consistent with the more common diagnosis of spontaneous bacterial peritonitis (SBP). The patient did not respond to antibacterial therapy, however, and the final diagnosis was only made with positive ascitic cultures that grew Candida glabrata. SFP should be considered in patients with either cardiac or cirrhotic ascites and have a delayed or lack of response to traditional SBP treatment. PMID:28386572

    Hirschsprung’s disease (HD) is an intestinal malformation caused by the innate absence of ganglion cells in the neural plexus of the colorectal wall, and is most common in male infants. It is rare in adult, and is usually left-sided. Herein we reported based on the CARE guidelines a case of a 47-year-old adult female suffering from “right-sided” HD complicated by refractory hypertension and cough. The patient with a history of cesarean section and with digestive unfitness (abdominal pain, distention, and constipation) only since 20 years old had recurrence of HD after initial surgery due to the incomplete removal of the HD-affected bowel based on a diagnosis of “chronic ileus”, leading to the relapse of the digestive symptoms and the emergence of some intractable circulatory and respiratory complications which could be hardly controlled by conservative treatment. During the long interval before coming to our department for help, she had been re-hospitalized for several times with various misdiagnoses and supplied merely with symptomatic treatment which could only achieve temporary symptomatic relief. At her admission to our department, the imaging examinations strongly indicated recurrent HD which was further supported by pathological examinations, and right hemi-colectomy was performed to remove the remnant aganglionic intestinal segment. Intraoperative and postoperative pathology supported the completeness of the definitive resection. Post-operation, the patient’s bowel motility significantly improved, and interestingly, the complications disappeared. For adult patients with long-term constipation combined with cough and hypertension, rare diseases like HD which requires definite surgery and which could be “right-sided” should not be overlooked. It is vital to diagnose and cure HD patients in childhood. Through the comparison of the two surgeries, it is noteworthy that for diagnosed HD, sufficient removal of the non-functional intestine confirmed

    This was a cohort analysis evaluating patients with pancreatic adenocarcinoma who presented with or developed ascites. Among the 180 patients analyzed, the use of serial paracenteses and indwelling catheters is a common practice to effect symptom palliation. The complication rate was higher in patients with indwelling catheters. Analyzing ascitic fluid and calculating the serum ascites albumin gradient can help attribute the etiology of the ascites and potentially identify which patients may benefit from diuretics or other intervention. Background Ascites develops in a subset of patients with pancreatic adenocarcinoma (PAC) at presentation or as the disease advances. Limited data exist on the prognostic importance of malignant ascites in PAC. Our hypothesis is that this information will provide an understanding of the natural history and facilitate management decisions. Methods We conducted a retrospective analysis of 180 patients treated at Memorial Sloan Kettering Cancer Center diagnosed between January 1, 2009 and December 31, 2014, with PAC and with ascites either at presentation or that developed during the disease course. Results For the 180 patients, the overall survival was 15 months. The time from diagnosis to ascites presentation was 11 months, and the survival time after ascites development was 1.8 months (range, 1.6–2.3 months; 95% confidence interval). Of 62 patients (34%) who had ascitic fluid analyzed, 36 (58%) had positive cytology. Fifty-one (82%) patients had a serum ascites albumin gradient ≥ 1, and 11 (18%) had serum ascites albumin gradient < 1. Sixty-four (36%) patients had their ascites managed solely by serial paracenteses. A total of 116 patients required a catheter; of these, 108 (93%) had a Tenckhoff catheter, 4 (3%) a Pleurx catheter, 4 (3%) a pigtail catheter, and 1 (1%) a Denver catheter. Eight (7%) patients required 2 catheters to be placed, and in 6 (5%), Tenckhoff catheters had to be removed. The main observed complications were

    To report the efficacy of super-selective intra-ophthalmic artery melphalan (IAM) for the treatment of refractory retinoblastoma and any associated complications of this treatment. A prospective case series. Eyes with retinoblastoma that had been treated with systemic chemotherapy or local therapy and had a relapse of their condition. All patients receiving IAM between May 2009 and September 2010 were included in the study. Intra-ophthalmic artery melphalan was offered to patients who had failed to respond adequately to systemic chemotherapy and local treatment where appropriate or because of a new recurrence of retinoblastoma that could not be treated with local therapies. None of the patients were excluded because of central nervous system abnormalities. Patients received 2 treatments of IAM given 4 weeks apart. All patients received an orthoptic assessment 3 weeks after each treatment and an examination under anesthesia (EUA). A third treatment was given if an unsatisfactory response was observed on EUA after 2 treatments. The response of the retinoblastoma tumor(s) and any associated local side effects from the treatment. A total of 15 eyes in 14 patients were treated with IAM during the study period. The mean age at the time of IAM was 31.5 months (median 17.3, range 11.2-150.7 months), and the mean follow-up was 8.7 months (3-16.3 months). Tumor control was achieved in 12 eyes (80%), and 12 eyes (80%) had local side effects that included third cranial nerve palsy in 6 (40%), orbital edema in 3 (20%), permanent retinal detachment in 1 (7%), and vitreous hemorrhage in 4 (27%). Seven eyes (47%) developed significant retinal pigment epithelium changes. Intra-ophthalmic artery melphalan is an effective treatment for retinoblastoma, achieving a high level of remission in refractory tumors. It can be associated with significant local side effects that can result in loss of vision and possible amblyogenesis. Clinicians and parents need to consider the benefits and

    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.

    Refractory ascites may appear in liver transplant recipients with recurrence of hepatitis C virus infection, even in the absence of advanced fibrosis. The mechanisms are unclear. The aim was to determine whether post-transplant cryoglobulinemia could be a predisposing factor for ascites in this population. Retrospective data of 82 liver transplant recipients with HCV recurrence surviving more than 1 year were collected. Cryoglobulinemia was systematically tested after transplantation. All patients had 1-year protocol biopsy with assessment of sinusoidal distension, perisinusoidal fibrosis, and centrolobular necrosis. Additional biopsies were performed when needed. Fourteen of 82 patients (17%) developed refractory ascites. When ascites appeared, fibrosis was stage F0-F1 in 36% and F2-F3 in 57%. Factors independently associated with post-transplant ascites were pretransplant refractory ascites (P = 0.001), fibrosis ≥stage 2 at 1 year (P = 0.002), perisinusoidal fibrosis at 1 year (P = 0.02), and positive cryoglobulinemia (P = 0.02). Patients with ascites had a significantly worse prognosis compared to those without ascites. Refractory ascites may occur in liver transplant recipients with HCV recurrence in the absence of advanced fibrosis. The finding that both positive cryoglobulinemia and perisinusoidal fibrosis at 1 year were significantly associated with ascites suggests that liver microangiopathy is involved in the mechanisms of HCV-related ascites. © 2014 Steunstichting ESOT.

    Some patients with refractory peritoneal dialysis-related peritonitis continue to develop intra-abdominal complications despite removal of the peritoneal catheter. Repeated percutaneous drainage or open laparotomy is often required, and mortality is not uncommon. The benefits of pelvic drainage placement during catheter removal in decreasing these complications and interventions remain unproven. Forty-six patients with refractory peritonitis who underwent removal of a Tenckhoff catheter between 1991 and 2013 were reviewed retrospectively. Twelve patients had pelvic drainage using closed active suction devices during catheter removal (drainage group). The remaining 34 patients underwent catheter removal without drainage (non-drainage group). The outcomes measured were the development of intra-abdominal complications and the requirement for repeated percutaneous drainage or open laparotomy within 90 days after the catheter removal. Baseline characteristics were similar with the exception of a higher median number of previous peritonitis episodes in the drainage group compared with the non-drainage group (2 vs 0, P = 0.02). During the follow-up period, intra-abdominal complications occurred in 15 (44%) of 34 patients in the non-drainage group, compared with one (8%) of 12 patients in the drainage group (P = 0.03). Twelve (35%) patients in the non-drainage group required repeated percutaneous drainage or open laparotomy for management, compared with zero (0%) patients in the drainage group (P = 0.02). Drain tubes were removed at a median of 6 days (inter-quartile range: 5-10) without complications.

    There are limited data regarding the effects of ascites on outcome of patients undergoing colorectal resection. We sought to identify complications related to ascites. The National Surgical Quality Improvement Program database was used to evaluate congestive heart failure (CHF) patients who had ascites before colorectal resection between 2005 and 2012. Multivariate regression analysis was performed to identify affected outcomes. We sampled a total of 2,178 patients who suffered CHF and underwent colorectal resection, of which 195 (9%) had preoperative ascites. The mortality rate of patients who had preoperative ascites was 46.2% compared to 25.7% for patients without ascites (adjusted odd ratio [AOR], 3.38; P < .01). Complications affected by ascites include (P < .05) ventilator dependency (AOR, 2.40), acute renal failure (AOR, 2.18), and wound disruption (AOR, 2.44; P < .05). There was no increase in superficial surgical site infection rate in patients with ascites (AOR, 1.01; P = .9). The presence of ascites in CHF patients is associated with increased mortality in patients undergoing colorectal surgery. There is no correlation between ascites and surgical site infection but wound disruption increases in the presence of ascites. Copyright © 2015 Elsevier Inc. All rights reserved.

    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

    Objective: To report a rare cause of cerebrospinal fluid ascites. Methods: A 37-year-old female with history of intracranial hypertension and a ventriculo-peritoneal shunt was referred to liver clinic for evaluation of newly developed ascites. Results: Initially, the cause of ascites was thought to be secondary to a liver etiology. However, this was excluded after a comprehensive evaluation including portal pressure measurements. We determined the ascites to be infected cerebrospinal fluid secondary to a rare commensal organism, Corynebacterium non-Jeikeium, which resolved after removing ventriculo-peritoneal shunt, appropriate antibiotics and conversion to a ventriculo-atrial shunt. Conclusion: Cerebrospinal fluid ascites is a rare complication of VP shunts and since 1976 only 8 cases of Corynebacterium non jk VP shunt infections have been reported in the literature but none associated with ascites. Also this report highlights the beneficial role of transjugular portal pressure measurements in the evaluation of ascites. PMID:27489721

    Gastroesophageal reflux disease is one of the most common comorbidities in patients with asthma. Gastroesophageal reflux disease can be linked to difficult-to-control asthma. Current management includes gastric acid suppression therapy and surgical antireflux procedures. The LINX® procedure is a novel surgical treatment for patients with gastroesophageal reflux disease refractory to medical therapy. To the best of our knowledge, we report the first case of successful treatment of refractory asthma secondary to gastroesophageal reflux disease using the LINX® procedure. Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting. LINX® is a viable alternative to the Nissen fundoplication procedure for the treatment of patients with

    We report the successful treatment of two patients with aneurismal subarachnoid hemorrhage complicated by severe respiratory failure and refractory septic shock using simultaneous prone position ventilation and high-volume hemofiltration. These rescue therapies allowed the patients to overcome the critical situation without associated complications and with no detrimental effects on the intracranial and cerebral perfusion pressures. Prone position ventilation is now an accepted therapy for severe acute respiratory distress syndrome, and high-volume hemofiltration is a non-conventional hemodynamic support that has several potential mechanisms for improving septic shock. In this manuscript, we briefly review these therapies and the related evidence. When other conventional treatments are insufficient for providing safe limits of oxygenation and perfusion as part of basic neuroprotective care in subarachnoid hemorrhage patients, these rescue therapies should be considered on a case-by-case basis by an experienced critical care team.

    Nonselective β-blockers (NSBBs), given to reduce the risk of variceal bleeding, have been associated with increased mortality in patients with cirrhosis and refractory ascites in some, but not all, studies. We performed a systematic review and meta-analysis to evaluate the effect of NSBBs on all-cause mortality in patients with cirrhosis and refractory ascites. We performed a comprehensive search of MEDLINE, Embase, Web of Science, and Scopus databases through January 2015, supplemented with a manual search. Trial-specific risk ratios (RRs) were pooled using the random-effects model. Our analysis included 3 randomized control trials and 8 observational studies of propranolol, carvedilol, nadolol, and metoprolol, reporting 1206 deaths among 3145 patients with ascites. The control groups received other interventions to prevent variceal bleeding. NSBB use was not associated with increased all-cause mortality in all patients with ascites (RR, 0.95; 95% confidence interval [CI], 0.67-1.35); nonrefractory ascites alone (RR, 0.96; 95% CI, 0.50-1.82), or refractory ascites alone (RR, 0.95; 95% CI, 0.57-1.61). Results were similar in randomized controlled trials and observational studies. Use of NSBBs was not associated with increased mortality at 6, 12, 18, and 24 months. Overall, the included studies had a medium to high risk of bias, except for 3 clinical trials in which the risk of biased was determined to be low. The use of NSBBs was not associated with a significant increase in all-cause mortality in patients with cirrhosis and ascites or refractory ascites. Certainty in the available estimates is low; a randomized trial of only patients with ascites is needed to answer this question. This meta-analysis does not support the position that NSBBs routinely be withheld from patients with ascites. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

    Ascites is the pathologic accumulation of fluid within the peritoneal cavity. There are many causes of fetal, neonatal and pediatric ascites; however, chronic liver disease and subsequent cirrhosis remain the most common. The medical and surgical management of ascites in children is dependent on targeting the underlying etiology. Broad categories of management strategies include: sodium restriction, diuresis, paracentesis, intravenous albumin, prevention and treatment of infection, surgical and endovascular shunts and liver transplantation. This review updates and expands the discussion of the unique considerations regarding the management of cirrhotic and non-cirrhotic ascites in the pediatric patient.

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

    Preeclampsia is defined as new onset hypertension and proteinuria after 20 weeks of gestation and complicates approximately 2-8% of all pregnancies. Release of vasoconstrictive agents, endothelial damage, hyperpermeability of the capillaries and microangiopathic haemolysis involves the basic pathophysiology. It has variable clinical presentation. Here, we report a case of severe preeclampsia who developed postpartum massive ascites and pleural effusion. Primigravid patient was admitted to our clinic at 35 weeks of gestation with very high blood pressure. In biochemical analysis, Alanine aminotransferase (ALT) was 401 U/L, Aspartate aminotransferase (AST) was 292 U/L. An emergency caesarean section was performed because of fetal distress. On the 2nd post-operative day, abdominal distension and severe abdominal pain occurred. On the 3rd post-operative day, her abdominal distension increased and Ultrasonography (USG) revealed massive ascites. Abdominal drainage was performed and albumin infusion was administered. On postoperative day 4, she still had abdominal distension and concomitant respiratory distress. Computed Tomography (CT) showed ascites and bilateral pleural effusion. Her complaint regressed on the following days.

    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.

    Massive ascites associated with cancerous peritonitis can result in severe respiratory discomfort and abdominal fullness. Additionally, it can significantly impair the activities of daily living of a patient, and relaxation is difficult to achieve, even with opioids. Frequent ascites drainage can cause rapid worsening of the patient's general condition, and a large amount of ascites can lead to discontinuation of anti-cancer treatment. Cell-free and concentrated ascites reinfusion therapy(CART)for refractory ascites was first covered by the insurance system in 1981. However, cancerous ascites includes many cellular components as well as mucus, and purification was a difficult process. Therefore, since the 1990s, CART disappeared from the field of cancer treatment. I have devised a Keisuke Matsusaki(KM)-CART system that has the ability to clean the filtration membrane. This system enables purification of massive cancerous ascites that may exceed 20 L. The general condition of the patients and their symptoms improve after use of KM-CART, making it possible to initiate or resume anti-cancer therapy. KM-CART helps remove unwanted components, such as cancer cells, cytokines, and vascular endothelial growth factors from the abdominal cavity through filtration of drained ascites. Therefore, the peritoneal environment can be improved, leading to enhancement of the efficacy of intraperitoneal chemotherapy. In addition, a large number of cancer cells and lymphocytes can be obtained with KM-CART, and it is possible to use these cells for customized cancer treatments, such as dendritic cell vaccine therapy, and to perform anti-cancer agent susceptibility testing. I believe that KM-CART is a good treatment approach for massive ascites associated with cancerous peritonitis.

We report a newborn with this rare vascular disorder associated with chylous ascites. The common mesenchymal origin of GVM and lymphatic vessels as well as the glomulin expression in vascular smooth muscle cells in utero could help explain this unusual prenatal complication of glomuvenous malformations.

    We report our experience with a radiologically placed peritoneal port-catheter in palliation of malignant ascites. Port-catheters were successfully placed under ultrasonographic and fluoroscopic guidance in seven patients (five women, two men) who had symptomatic malignant ascites. The long-term primary patency rate was 100%. The mean duration of catheter function was 148 days. Seven patients had a total of 1040 port-days. Two patients received intraperitoneal chemotherapy via the port-catheter. There were no procedure-related mortality and major complications. Minor complications such as ascitic fluid leakage from the peritoneal entry site, migration of the catheter tip to the right upper quadrant, and reversal of the port reservoir occurred in four patients. None of these complications affected the drainage and required port explantation. In patients with symptomatic malignant ascites, a peritoneal port-catheter can provide palliation and eliminate multiple hospital visits for repeated paracentesis with high patency and low complication rates.

    Mendelian susceptibility to mycobacterial disease is a rare clinical condition characterized by a predisposition to infectious diseases caused by poorly virulent mycobacteria. Other infections such as salmonellosis and candidiasis are also reported. The purpose of this article is to describe a young boy affected with various infectious diseases caused by Mycobacterium tuberculosis complex, Salmonella sp, Klebsiella pneumonie, Citrobacter sp., and Candida sp, complicated with severe enteropathy and transient hypogammaglobulinemia. We reviewed medical records and performed flow cytometry staining for lymphocyte populations, lymphocyte proliferation in response to PHA, and intracellular IFN-γ production in T cell PHA blasts in the patient and a healthy control. Sanger sequencing was used to confirm the genetic variants in the patient and relatives. Genetic analysis revealed a bi-allelic mutation in IL12RB1 (C291Y) resulting in complete IL-12Rβ1 deficiency. Functional analysis demonstrated the lack of intracellular production of IFN-γ in CD3+ T lymphocytes from the patient in response to rhIL-12p70. To our knowledge, this is the third patient with MSMD due to IL-12Rβ1 deficiency complicated with enteropathy and hypogammaglobulinemia and the first case of this disease to be described in Colombia.

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

    Background and Aims. Fecal microbiota transplantation (FMT) is a highly effective treatment option for refractory Clostridium difficile infection (CDI). FMT may be challenging in patients with a low performance status, because of their poor medical condition. The aims of this study were to describe our experience treating patients in poor medical condition with refractory or severe complicated CDI using FMT via the upper GI tract route. Methods. This study was a retrospective review of seven elderly patients with refractory or severe complicated CDI and a poor medical condition who were treated with FMT through the upper GI tract route from May 2012 through August 2013. The outcomes studied included the cure rate of CDI and adverse events. Results. Of these seven patients who received FMT via the upper GI tract route, all patients were cured. During the 11-month follow-up period, CDI recurrence was observed in two patients; rescue FMT was performed in these patients, which led to a full cure. Vomiting was observed in two patients. Conclusions. FMT via the upper gastrointestinal tract route may be effective for the treatment of refractory or severe complicated CDI in patients with a low performance status. Physicians should be aware of adverse events, especially vomiting. PMID:27127501

    Massive ascites of unknown origin is an uncommon condition, which represent a diagnostic challenge. Patients with delayed diagnosis and treatment may have a poor prognosis. A 22-year-old female was referred to this hospital due to a 4-year progressive abdominal distension with massive ascites of unknown origin. By thorough investigations, she was eventually diagnosed as chronic calcified constrictive pericarditis. She received pericardiectomy and had an uneventful postoperative course. With a few day paracentesis, ascites did not progress any more. She was doing well at 5-month follow-up and has returned to work. Extracardiac manifestations, such as massive ascites and liver cirrhosis, were rare in patients with constrictive pericarditis. Pericardiectomy can be a radical solution for the treatment of chronic constrictive pericarditis. In order to avoid delayed diagnosis and treatment, physicians have to bear in mind this rare manifestation of chronic calcified constrictive pericarditis. PMID:24600502

    2014-01-01

    Ascites is the pathologic accumulation of fluid within the peritoneal cavity. Because many diseases can cause ascites, in particular cirrhosis, samples of ascitic fluid are commonly analyzed in order to develop a differential diagnosis. The concept of transudate versus exudate, as determined by total protein measurements, is outdated and the use of serum-ascites albumin gradient as an indicator of portal hypertension is more accurate. Lactate dehydrogenase (LDH), vascular endothelial growth factor (VEGF), and other tumor markers can be helpful in distinguishing between malignant and benign conditions. Glucose and adenosine deaminase levels may support a diagnosis of tuberculous disease, and amylase level may indicate a diagnosis of pancreatitis. Given the specificity and sensitivity of laboratory results, accurate diagnosis should be based on both laboratory data and clinical judgment. PMID:26357618

    Portal hypertension (PH) plays an important role in the natural history of cirrhosis, and is associated with several clinical consequences. The introduction of transjugular intrahepatic portosystemic shunts (TIPS) in the 1980s has been regarded as a major technical advance in the management of the PH-related complications. At present, polytetrafluoroethylene-covered stents are the preferred option over traditional bare metal stents. TIPS is currently indicated as a salvage therapy in patients with bleeding esophageal varices who fail standard treatment. Recently, applying TIPS early (within 72 h after admission) has been shown to be an effective and life-saving treatment in those with high-risk variceal bleeding. In addition, TIPS is recommended as the second-line treatment for secondary prophylaxis. For bleeding gastric varices, applying TIPS was able to achieve hemostasis in more than 90% of patients. More trials are needed to clarify the efficacy of TIPS compared with other treatment modalities, including cyanoacrylate injection and balloon retrograde transvenous obliteration of gastric varices. TIPS should also be considered in bleeding ectopic varices and refractory portal hypertensive gastropathy. In patients with refractory ascites, there is growing evidence that TIPS not only results in better control of ascites, but also improves long-term survival in appropriately selected candidates. In addition, TIPS is a promising treatment for refractory hepatic hydrothorax. However, the role of TIPS in the treatment of hepatorenal and hepatopulmonary syndrome is not well defined. The advantage of TIPS is offset by a risk of developing hepatic encephalopathy, the most relevant post-procedural complication. Emerging data are addressing the determination the optimal time and patient selection for TIPS placement aiming at improving long-term treatment outcome. This review is aimed at summarizing the published data regarding the application of TIPS in the management of

    The protein concentration in ascites is usually low in cirrhosis because capillarization and defenestration of the sinusoids limit diffusion of large proteins from plasma to the space of Disse. However, some cirrhotic patients have high-protein ascites (HPA). The aim of this study was to describe and compare the characteristics and prognosis between cirrhotic patients with HPA (>20 g/l) and patients with low-protein ascites (LPA). In this longitudinal observational prospective cohort study, all consecutive cirrhotic patients with ascites hospitalized in our tertiary liver center were included and followed for up to 2 years, provided that they had no other cause of HPA. HPA was defined as protein concentrations of more than 20 g/l. Among 107 patients included, 19 (17.8%) had HPA. HPA patients had more refractory ascites (63 vs. 34%), better liver functions, and a higher 1-year transplant-free survival rate compared with LPA patients (P<0.05). Portal hypertension parameters were not different. During follow-up, 47% of HPA patients were treated by transjugular intrahepatic portosystemic shunts versus 18% of LPA patients, whereas 15 LPA patients required liver transplantation for end-stage liver disease versus only one HPA patient. We observed higher protein filtration and less pericellular, centrilobular, and sinusoidal fibrosis in cirrhotic HPA livers compared with LPA livers. Almost 20% of cirrhotic patients with ascites have HPA (>20 g/l). These patients have better liver functions and a higher 1-year survival than those with LPA, even though ascites are more often refractory.

    Myxedema ascites caused by hypothyroidism is rare, so its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a 71-yr-old man with clinical ascites that was the first manifestation of hypothyroidism, and which resolved completely in response to thyroid hormone replacement therapy. To our knowledge, this is the first report of myxedema ascites in Korea. A review of the literature revealed 51 well-documented cases of myxedema ascites. Analyses of ascites from patients in this condition usually show high protein (>2.5 g/dL) and low white blood cell counts, with a high proportion of lymphocytes. A consistent feature is the good response to thyroid hormone replacement therapy, which has always led to resolution of the ascites. Myxedema ascites is thus rare but easy to treat; it should be borne in mind, especially if the ascites fluid has a high protein content. PMID:16891828

    2014-01-01

    Cirrhosis affects millions of people throughout the world. Two of the most serious complications of liver cirrhosis are ascites and spontaneous bacterial peritonitis (SBP). The development of ascites is related to the severity of portal hypertension and is an indicator of increased mortality. Although sodium restriction and diuretic therapy have proven effective, some patients may not respond appropriately or develop adverse reactions to diuretic therapy. In such cases, interventions such as transjugular intrahepatic portosystemic shunt (TIPS) placement are warranted. SBP is a complication of ascites that confers a very high mortality rate. Recognition and prompt treatment of this condition is essential to prevent serious morbidity and mortality. Initiation of prophylaxis in SBP remains controversial. Given the burden of liver cirrhosis on the health care system, ascites and SBP will continue to provide challenges for the primary care provider, hospitalist, internist, and gastroenterologist alike.

    Treatment of refractory ulcerative colitis (UC) is a common clinical challenge. In either acute or chronic refractory UC, the disease may continue to remain active, even though the patient is on appropriate therapy. It is important to reassess and characterize the patient's disease before adding new medications to the current medical regimen. After determining the current extent and severity of the UC—ruling out other causes of bloody diarrhea and determining what complications are present—new treatment approaches can then be started. It is critical to first optimize oral 5-aminosalicylic acid (5-ASA) therapy combined with rectal 5-ASA or corticosteroid suppositories, plus corticosteroid or 5-ASA enemas or foam preparations. Oral or intravenous corticosteroids are appropriate to use if needed, but alternative approaches must be used for long-term maintenance. 6-Mercaptopurine (6-MP) or azathioprine can be very helpful for severe chronic refractory UC. In those patients who do not respond to 5-ASA medications, corticosteroids, and 6-MP or azathioprine, infliximab offers an important approach for induction and maintenance of remission for refractory chronic ulcerative colitis as well as for select cases of refractory acute UC. Cyclosporine use is an alternative medical approach for the refractory acute UC patient. Colectomy with ileal pouch-anal anastomosis remains a valuable option for the refractory chronic or acute UC patient, because it can provide both a “cure” for the disease, as well as eliminate ineffective medications with their associated side effects.

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

    Breeding against a production disease is complicated by multiple relationships between productivity, disease, and environment. Ascites in broilers is such a disease. The combination of the reasonably well understood etiology (a physiological/pathological cascade due to inadequate oxygen supply) and the practical relevance makes ascites a relevant case for demonstrating and partly revealing these complex relationships. Chickens (n = 2,788) were tested in an ascites-challenging (cold) environment. Genetic analysis of mortality and pathology in combination with performance and physiological traits (especially blood gas traits) revealed ample opportunities for selection against ascites expression. The genetic correlation structure indicated that different mortality traits and pathology traits roughly represent one common characteristic. Direct selection against pathology is more effective than selection on the basis of growth or blood gas traits. The observed negative correlation (-0.26) between productivity and ascites was unexpected. From the etiology of ascites (inadequate supply of oxygen relative to the demand), a positive (unfavorable) correlation was expected. To demonstrate that the actual disease occurrence caused this apparent contradiction, the data from the undiseased subpopulation were reanalyzed. In the undiseased subpopulation, the genetic correlation between productivity and ascites was positive (0.29). This discrepancy was confirmed by comparing regression of ascites expression on actual performance with regression of ascites on independently assessed performance breeding values. The lability of the genetic correlation was explained from complex interactions between productivity, disease susceptibility, and actual occurrence of the disease. The revealed mechanism can be generalized to other production-related diseases and results in systematically lower genetic correlations between disease and productivity. It was inferred that genetic correlations

    Ascites can be defined as accumulation of free fluid in the peritoneal cavity. It is the most common complication of cirrhosis and is associated with a poor quality of health, increased risks of infections, renal failure and a poor long-term outcome. This descriptive analytical study was conducted on one hundred and fifty diagnosed patients of ascites consecutively admitted in medical unit of tertiary care facility attached to Muhammad Medical College, Mirpur Khas, Sindh, from Oct 2006 to Sep 2008. Special proforma was prepared containing patients' basic information, history, clinical findings and investigations necessary to diagnose the cause of ascites. Patients with ascites due to perforation and intraperitoneal bleeding were excluded from the study. Serum-ascitic albumin gradient (SAAG) was calculated and patients were grouped into high and low SAAG groups. The obtained data was analysed using SPSS- 11. In this study 150 patients of ascites were included. Patients were arranged in two groups. High SAAG 'high portal pressure' group and low SAAG 'low portal pressure' group. In high SAAG group patients included were 128 (85.33%), and in low SAAG group patients included were 22 (14.66%). In high SAAG group, out of 128 (85.33%) patients 122 (81.33%) were of cirrhotic ascites, [(viral hepatitis B, C and combined 105 (70%), alcoholic 7 (4.66%), cryptogenic 10 (6.66%)], heart failure ascitic patients were 5 (3.33%), and constrictive pericarditis 1 (0.66). In low SAAG group out of 22 (14.66%) patients malignant ascites was (primary peritoneal carcinomatosis and metastasis) 11 (7.33%), tuberculous ascites was 10 (6.66%), and ascites due to nephrotic syndrome was 1 (0.66%).

Traditional methods involving ligation of lymphatic fistulas or small bowel resection do not address the basic pathophysiologic mechanism of the underlying obstruction, and identification of chyloperitoneal fistulas may be challenging. A novel flap based on deep inferior epigastric vessels with its surrounding lymphatic fatty tissue was designed in this study and transferred into abdominal cavity, with anastomosis to the fourth jejunal vessels. Three consecutive cases with chylous ascites treated by this vascularized lymphatic cable transfer were retrospectively reviewed. All three patients recovered from chylous ascites after the lymphatic cable transfer and tolerated regular diet well, with follow-up of 3 years at least. Lymphatic cable flap based on the deep inferior epigastric vessels could be a potential option for treatment of intractable chylous ascites, with safe and successful long-term outcomes in three consecutive patients. The proposed functional mechanism of the flap is bypass of the obstructed intra-abdominal lymphatics to an extraperitoneal route as well as local lymphangiogenesis.

    POEMS syndrome is a multisystem disorder characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. POEMS syndrome is a rare cause of refractory ascites. We report the case of a patient with POEMS syndrome presenting with massive ascites who was treated with very-low-dose lenalidomide and dexamethasone. A 57-year-old Japanese man was admitted to our hospital with pleural effusion, massive ascites, and leg edema. The diagnosis of POEMS syndrome was made based on the combination of the following findings: peripheral neuropathy, organomegaly, endocrinopathy, serum monoclonal protein elevation, skin changes, plasma VEGF elevation, and evidence of extravascular volume overload. Renal dysfunction induced by biopsy-proven renal involvement of POEMS syndrome was observed. Massive ascites of the patient dramatically diminished with long-time treatment of very-low-dose lenalidomide and dexamethasone. Lenalidomide seems to be a very promising therapy for POEMS syndrome presenting with extravascular volume overload such as edema, pleural effusion, and ascites. Very-low-dose lenalidomide might be effective especially for the patients with POEMS-related nephropathy. PMID:24782932

    Fourteen patients in whom peritoneovenous shunts were inserted for intractable ascites or malignancy were reviewed. Reduction in ascites was obtained in all patients by the time of discharge with significant diuresis and weight loss. Significant decrease in haemoglobin, packed cell volume, platelet count and prothrombin time also occurred. Coagulation studies were abnormal in 60 per cent of patients in whom they were performed with bruising or detectable bleeding occurring in 28.5 per cent of all patients. Late blockage of the shunt occurred in five patients and was less frequent in Denver than in Le Veen type shunts. Cumulative mortality one month after shunt insertion was 28.5 per cent and at one year was 78.5 per cent reflecting the severity of the underlying disease. Peritoneovenous shunting should be reserved for palliation in patients resistant to full conventional medical therapy. PMID:4095803

  14. Management of ascites with hydrothorax

    Hydrothorax occurs in 5.3 percent of ascitic patients. Experience with 22 cases forms the basis of this report. Of the 22 cases, 21 were spontaneous and 1 was due to transdiaphragmatic incision. Usually fluid enters the chest through tiny defects in the diaphragm. These defects are often covered by pleuroperitoneum, but the high abdominal pressure raises a bleb on the superior surface of the diaphragm. Rupture produces hydrothorax. The ascites is often relieved with the onset of the hydrothorax. Blockage of the thoracic duct has produced chylous ascites. The thoracoabdominal communication is immediately confirmed by a scan of the chest and abdomen after intraperitoneal injection of technetium-99 colloid. The rate at which the technetium-99 enters the chest is related to the size of the defect in the diaphragm. A significant transfer should occur within 12 hours. Immediate transfer occurs with large defects. The ruptured blister on the diaphragm forms a one-way valve. Intrathoracic injection does not migrate into the peritoneal cavity. The valvular characteristics of the leak force ascitic fluid into the thorax because the differential pressure between the abdominal and pleural cavities is intensified by inspiration. If tension hydrothorax has occurred, urgent thoracocentesis and paracentesis may be required. A chest tube should not be introduced. The main principle of surgery is to supply a low resistance pathway for the return of fluid to the venous system and to eliminate the diaphragmatic defect by obliteration of the pleural space. A LeVeen peritoneovenous shunt is performed after emptying the abdomen of its fluid load. After completion of the shunt operation, the chest is emptied of fluid, and a sclerosing agent (tetracycline or nitrogen mustard) is injected into the pleural cavity. With this regime, the defect closed or was rendered insignificant in 18 of 22 patients.

    Refractory plasmonics deals with metallic nanostructures that can withstand high temperatures and intense laser pulses. The common belief was that refractory materials such as TiN are necessary for this purpose. Here we show that refractory plasmonics is possible without refractory materials. We demonstrate that gold nanostructures which are overcoated with 4 and 40 nm Al2O3 (alumina) by an atomic layer deposition process or by thick IC1-200 resist can withstand temperatures of over 800 °C at ambient atmospheric conditions. Furthermore, the alumina-coated structures can withstand intense laser radiation of over 10 GW/cm(2) at ambient conditions without damage. Thus, it is possible to combine the excellent linear and nonlinear plasmonic properties of gold with material properties that were believed to be only possible with the lossier and less nonlinear refractory materials.

    Less than four percent of patients with hypothyroidism develop ascites. Ascites as the presenting feature of hypothyroidism is uncommon, hence diagnosis is often delayed. Once it is diagnosed, treatment of hypothyroidism leads to quick clinical improvement in ascites. We report a case of a female patient who presented with ascites secondary to severe hypothyroidism and discuss the diagnostic characteristics of the ascitic fluid in myxedema ascites on the basis of literature review.

    To evaluate the effect of computed tomography (CT) attenuation values of ascites on gastrointestinal (GI) perforation site prediction. The CT attenuation values of the ascites from 51 patients with GI perforations were measured by volume rendering to calculate the mean values. The effect of the CT attenuation values of the ascites on perforation site prediction and postoperative complications was evaluated. Of 24 patients with colorectal perforations, the CT attenuation values of ascites were significantly higher than those in patients with perforations at other sites [22.5 Hounsfield units (HU) vs 16.5 HU, respectively, P = 0.006]. Colorectal perforation was significantly associated with postoperative complications (P = 0.038). The prediction rate of colorectal perforation using attenuation values as an auxiliary diagnosis improved by 9.8% compared to that of CT findings alone (92.2% vs 82.4%). The CT attenuation values of ascites could facilitate the prediction of perforation sites and postoperative complications in GI perforations, particularly in cases in which the perforation sites are difficult to predict by CT findings alone.

    1. B- and M-mode echocardiography was used to compare cardiac function in broilers with spontaneous ascites syndrome with that of normal chickens. 2. Thirty ascitic chickens and 15 normal chickens aged three, 4, 5, and 6 weeks from the same flock (180 birds in total) were examined. They were restrained gently in a natural standing position, and echocardiographs were obtained from a 7.0-MHz linear transducer placed on the left pectoral apterium. Indices of cardiac structure and functioning were calculated from the echocardiographs, and some were normalised to body weight. Heart rate was also measured. 3. All cardiac structural indices in both ascitic and normal chickens increased with age. Compared with normal chickens, right ventricular diameter at the end of systole in ascitic chickens was greater at 4, 5 and 6 weeks of age. Ventricular septal thickness at the end of both systole and diastole was greater in ascitic chickens at 5 and 6 weeks. Left ventricular free wall thickness at the end of diastole was less in ascitic chickens at 3 weeks. However, all the structural indices decreased with age after normalisation with body weight. 4. The heart rate of ascitic chickens was lower at 4, 5 and 6 weeks. Normalised left ventricular fractional shortening was lower in ascitic chickens at 4, 5 and 6 weeks, as was normalised right ventricular fractional shortening. Incrassation of the ventricular septum (Delta T), which changed little in normal chickens, was less at 4, 5 and 6 weeks in ascitic chickens. Left ventricular fractional shortening, right ventricular fractional shortening and Delta T were all negatively correlated with ascites heart index at all ages. 5. Taken together the results suggest heart failure of both ventricle, but that right ventricular dysfunction is more extensive than left ventricular dysfunction. We suggest that secondary pulmonary hypertension would result in these ascitic chickens due to volume overload.

    Patients with cirrhosis and portal hypertensive complications have reduced survival. As such, it has been suggested that nonselective beta-blocker therapy in patients with advanced ascites is harmful. The aim of this study was, therefore, to determine the risk of mortality in patients with cirrhosis and ascites taking nonselective beta-blocker therapy for the prevention of variceal hemorrhage. This study was a retrospective analysis of 2,419 patients with cirrhosis and portal hypertension admitted to Parkland Memorial Hospital (a university-affiliated county teaching hospital) from 2003-2010. Patients were subdivided into those with varices only, ascites only and those with both varices and ascites. The primary outcome measure for this study was all-cause in-hospital mortality. Overall, 68 of 1,039 (6.5%) patients taking beta-blockers died during their hospitalization, while 223 of 1,380 (16.2%) patients not taking beta-blockers died (P < 0.001). Beta-blocker use was also assessed in specific cohorts; mortality was 21.1% in patients with severe ascites with varices who were not taking beta-blockers compared with 8.9% in patients who were taking beta-blockers (P = 0.05). Overall, fewer patients taking beta-blockers died compared with those not taking beta-blockers in patients with varices only (6.4% versus 12.1%) and those with ascites with or without varices (6.6% versus 18.1%) (P < 0.001). Mortality was lower in patients with cirrhosis and portal hypertension taking nonselective beta-blockers than in those not taking beta-blockers. The use of nonselective beta-blockers provided a significant survival benefit in patients with all grades of ascites, including those with severe ascites.

    Al2O3-C refractories were first fabricated in a coke bed at 1673 K (1400 °C) using tabular corundum, reactive alumina, carbon black, silicon, and microsilica as the starting materials and phenol resin as the binder. Then the alkali attack resistance of those materials was conducted in the powder mixture of carbon black and potassium carbonate (1:1 wt pct) in a graphite crucible at 1273 K (1000 °C) for 10 hours. The correlation between pore size, permeability of Al2O3-C refractories, and their alkali (K2CO3) attack was investigated by means of mercury intrusion porosimetry, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results showed that the pore structure of Al2O3-C refractories was controlled by the addition of silicon, ultrafine reactive alumina, and microsilica to in-situ form SiC whiskers and mullite in the preparation process. The mean pore size of Al2O3-C refractories was strongly associated with permeability. With the decrease of the mean pore size, the permeability of the Al2O3-C refractories reduced constantly. The alkali attack test also verified that the Al2O3-C refractories with lower permeability had better alkali corrosion resistance, because the penetration of K vapor into the materials could be restricted effectively. The corrosion mechanism of Al2O3-C refractories supposes that (1) K2CO3 was reduced to K vapor and penetrated into the specimen through the open pores and (2) K vapor reacted with SiC, SiO2, and alumina to form KAlSi2O6 and KAlSiO4, which is in agreement with the thermodynamic prediction.

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

    The stromal Leydig cell tumour (SLCT), a very rare, benign neoplasm was described in 75-year old woman. The patient presented the typical signs of virilisation (hirsutism, masculine alopecia, moderate clitoris enlargement, deep voice) as well as hypertension and insulin independent type of diabetes mellitus (IIDM). Additionally, she had marked ascites (3400 ml as established during surgery). The serum concentration of testosterone before the surgery was elevated up to 7.6 ng/ml. FSH and LH were at very low range (2.5 mIU/ml, 3.4 mIU/ml, respectively) whereas 17 beta-oestradiol was elevated (56 pg/ml). Total abdominal hysterectomy with salpingo-oophorectomy (TAH/BSO) and omentectomy were performed. The histopathological findings revealed stromal Leydig cell tumour with Reinke crystalloids. The postoperative follow-up was complicated by venous thrombosis. Five weeks after the surgery only slight regression of the signs of virilisation was observed. Hormonal findings were adequate to the patient age range (FSH--16.7 mIU/ml, LH--21.1 mIU/ml, testosterone--0.19 ng/ml, 17 beta-oestradiol concentration below 10 pg/ml).

    The 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. A 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. There 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). Tunneled 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.

    Ultrasonography enables the examiner to detect very small amounts of fluid in the peritoneal cavity and to determine its location, amount, and sonographic features. The pathologic process responsible for the ascites, for example, ileus, hepatic fibrosis, thrombosis of the caudal vena cava, or traumatic reticuloperitonitis, often can be identified. Abdominocentesis and analysis of the aspirated fluid allow differentiation of inflammatory and noninflammatory ascites as well as the diagnosis of uroperitoneum, hemoperitoneum, chylous ascites, and bile peritonitis.

    Large-volume paracentesis (LVP) is the treatment of choice for patients with cirrhosis and refractory ascites. However, LVP can lead to postparacentesis circulatory dysfunction (PCD), which is associated with faster ascites recurrence and renal failure. PCD results from vasodilatation, which reduces effective blood volume, and is prevented by intravenous administration of albumin. Vasoconstrictors could be used instead of albumin and, with longer use, prevent PCD and delay ascites recurrence. We performed a multicenter, randomized, double-blind, placebo-controlled trial to compare albumin with the vasoconstrictor combination of octreotide and midodrine in patients with refractory ascites who underwent LVP. Patients in the albumin group received a single intravenous dose of albumin at the time of LVP plus placebos for midodrine and octreotide (n = 13). Patients in the vasoconstrictor group received saline solution (as a placebo for albumin), 10 mg of oral midodrine (3 times/day), and a monthly 20-mg intramuscular injection of long-acting octreotide (n = 12). Patients were followed up until recurrence of ascites. The median times to recurrence of ascites were 10 days in the albumin group and 8 days in the vasoconstrictor group (P = .318). There were no significant differences in PCD between the albumin group (18%) and the vasoconstrictor group (25%, P = .574). When ascites recurred, serum levels of creatinine were higher in the vasoconstrictor group (1.2 vs 0.9 mg/dL in the albumin group; P = .051). The combination of midodrine and octreotide after LVP is not superior to albumin in delaying recurrence of ascites or preventing PCD in patients with cirrhosis. Outcomes appear to be worse in patients given octreotide and midodrine. ClinicalTrials.gov number, NCT00108355. Copyright © 2012 AGA Institute. Published by Elsevier Inc. All rights reserved.

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

    Systemic rheumatoid vasculitis (SRV) can develop in rheumatoid arthritis of long duration and high disease activity. It most commonly manifests as cutaneous vasculitis and mononeuritis multiplex. This can involve any organ of the body and carries very high mortality. We report a case of a young male who had rheumatoid arthritis for the past 15 years and became refractory to standard drugs and anti-TNF agents. He subsequently developed SRV, which started as mononeuritis multiplex. Disease progressed to result in gangrene of hands and feet despite receiving intravenous cyclophosphamide.

    Systemic rheumatoid vasculitis (SRV) can develop in rheumatoid arthritis of long duration and high disease activity. It most commonly manifests as cutaneous vasculitis and mononeuritis multiplex. This can involve any organ of the body and carries very high mortality. We report a case of a young male who had rheumatoid arthritis for the past 15 years and became refractory to standard drugs and anti-TNF agents. He subsequently developed SRV, which started as mononeuritis multiplex. Disease progressed to result in gangrene of hands and feet despite receiving intravenous cyclophosphamide. Intravenous immunoglobulin and rituximab also could not provide any response. Prolonged ICU stay resulted in critical care neuromyopathy. Central nervous system vasculitis developed even after repeated infusions of intravenous immunoglobulins and at last he died of complications. In this case report, we have presented rare and chronic protracted presentation of rheumatoid vasculitis involving skin, nerves, brain and testis, which was refractory to the recommended therapies.

    Massive hemorrhagic ascites (4470 mL, range 1-10 L) in women with endometriosis is a rare condition occurring predominantly in black women. Of the 43 case reports published, 42 are compatible with the hypothesis that the hemorrhagic ascites is predominantly a consequence of excessive ovarian transudation similar to a Meigs syndrome. Indeed, bilateral ovariectomy cures the condition without recurrences, whereas after unilateral ovariectomy or cystectomy recurrence rate is more than 50%; during ovarian suppression by luteinizing hormone-releasing hormone agonist ascites disappears, but reappears after treatment. Superficial pelvic endometriosis also contributes to the ascites because after superficial endometriosis destruction the recurrence rate is only 4 in 14. Based on these data, it is suggested, to scrutinize the ovaries for tumors given the analogy with Meigs syndrome. In women desiring fertility, conservative treatment with destruction of endometriosis only can be attempted given the cure rate of some 20%. It is unknown what the effect of ovulation induction would be.

    One hundred and forty patients with an intractable ascites complicating a chronic liver disease received a peritoneovenous shunt (PVS) using the LeVeen valve. Operative mortality was ten per cent but was 25% in patients with severe liver failure. Intraoperative drainage of ascites sharply decreased postoperative complications and mortality. One-year actuarial survival rate was 81.4%, respectively 77.7%, 61.3%, and 24.7% in patients with good liver function and moderate or severe liver failure. Variceal hemorrhage occurred in 11 patients and late infection in another 11 patients. Thirty-eight patients (30.5%) had recurrence of ascites. This was mostly due to an obstruction on the venous side of the shunt. An elective portacaval shunt had to be done in 23 patients for recurrence of ascites or variceal bleeding. Among the 57 patients still alive at time of writing, 51 were free of ascites. These results suggest that PVS is an efficient operation. This procedure may be largely indicated in the selected and small group of cirrhotic patients with true intractable ascites and moderate or no liver insufficiency. Images FIG. 1. FIG. 2.

    Ascites often contributes to patient morbidity and discomfort. When refractory to medical management, it has been managed with repeated paracentesis, implantable ports for drainage, or diversion to the urinary bladder. Peritoneovenous shunt insertion has been a technique that was traditionally performed only by surgeons but is now within the realm of interventional radiologists. Its advantage is that protein-rich ascitic fluid is returned to the intravascular compartment. This retrospective study elaborates on the successes and problems encountered during shunt insertion in our first 13 patients. Two patients are well with a functioning shunt at 14 and 32 weeks. In 6 the shunt functioned until the patients' death from the underlying malignancy. Two required revision with variable success and in 2, shunt function could not be salvaged. There was one procedure-related mortality. Radiological insertion of these shunts is feasible and should be considered for selected patients. Options are available for assessment and salvaging of dysfunctional shunts.

    This study was designed to investigate the association between infectious ascites, clinical parameters and treatment outcomes after hepatectomy. Of 891 patients who underwent hepatectomy between 2006 and 2013, 74 who underwent paracentesis for bacterial cultivation of postoperative ascites after hepatectomy were analyzed. Of the 74 patients, 42 had positive bacterial cultures (positive group) and 32 patients had negative cultures (negative group). Hospital mortality was significantly higher in the positive group than in the negative group [9/42 (21.4%) vs. 2/32 (6.3%); P = 0.035]. Hospital mortality associated with each bacterial strain was as follows: methicillin-resistant staphylococci (MRS) (5/13, 38.5%), staphylococci (2/11, 18.2%), enterococci (2/12, 16.7%), Enterobacter (0/3, 0%), Klebsiella (0/2, 0%), and others (0/1, 0%). Cox proportional multivariate analysis revealed that MRS infection in ascites was the only risk factor of hospital death (HR = 5.08, P = 0.041) and MRS wound infection was the only risk factor to predict MRS infection in ascites (HR = 5.67, P = 0.015). Postoperative MRS infection in postoperative ascites after hepatectomy is a potentially fatal complication; therefore, the prevention of MRS wound infection is critical to decrease postoperative hospital mortality. © 2014 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    Malignant ascites is one of the common complication at the late stage of abdominal cancers, which may deteriorate the environment of abdominal cavity and lead to potential damage of functional cells. Interstitial cells of Cajal (ICCs) are mesoderm-derived mesenchymal cells that function normal gastrointestinal motility. The pathological changes of ICCs or the reduced number may lead to the motility disorders of gastrointestinal tract. In this study, through analysis of malignant ascites which were obtained from cancer patients, we found that inflammatory cells, including tumour-infiltrating lymphocytes, accounted for 17.26 ± 1.31% and tumour-associated macrophages, occupied 19.06 ± 2.27% of total cells in the ascites, suggesting these inflammatory cells, in addition to tumour cells, may exert important influence on the tumour environment of abdominal cavity. We further demonstrated that the number of mice ICCs were significant decreased, as well as morphological and functional damage when ICCs were in the simulated tumour microenvironment in vitro. Additionally, we illustrated intestinal myoelectrical activity reduced and irregular with morphological changes of ICCs using the mice model of malignant ascites. In conclusion, our data suggested that inflammatory cells in malignant ascites may damage ICCs of the small intestine and lead to intestinal motility disorders. PMID:26087333

    Malignant pleural effusion (PE) and ascites, common clinical manifestations in advanced cancer patients, are associated with a poor prognosis. However, the biological characteristics of malignant PE and ascites are not clarified. Here we report that malignant PE and ascites can induce a frequent epithelial-mesenchymal transition program and endow tumor cells with stem cell properties with high efficiency, which promotes tumor growth, chemoresistance, and immune evasion. We determine that this epithelial-mesenchymal transition process is mainly dependent on VEGF, one initiator of the PI3K/Akt/mechanistic target of rapamycin (mTOR) pathway. From the clinical observation, we define a therapeutic option with VEGF antibody for malignant PE and ascites. Taken together, our findings clarify a novel biological characteristic of malignant PE and ascites in cancer progression and provide a promising and available strategy for cancer patients with recurrent/refractory malignant PE and ascites. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

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

Video description of the case, demonstration of the surgical technique, discussion of the histology, and review of endometriosis-associated ascites. Tertiary referral center. A 26-year-old nulliparous woman of Nigerian heritage with recurrent hemorrhagic ascites due to endometriosis. Three years previously she underwent an exploratory laparotomy for similar symptoms, and 7 L of hemorrhagic ascites were evacuated from her abdomen. Friable lesions covering the peritoneum of the uterus, bladder, and pouch of Douglas were biopsied and consistent with endometriosis. After her initial surgery, the patient was hormonally suppressed with goserelin for 3 months and oral medroxyprogesterone for 1 year. She then stopped the medications to attempt pregnancy but was unsuccessful. She used clomiphene for 3 months, and the ascites reaccumulated. The patient was started on depot leuprolide and oral norethindrone, but the ascites persisted. The patient underwent small-diameter laparoscopy using a multipuncture technique, evacuation of 7.8 L of hemorrhagic ascites, enterolysis, appendectomy, chromopertubation, and treatment of the endometriosis. Diffuse olive-green "mossy" endometriosis lesions blanketed the pelvic and abdominal peritoneum. The endometriosis was surgically resected with a combination of peritoneal stripping, excision with carbon dioxide laser, and ablation with neutral argon plasma. Examination of the ascites showed scattered hemosiderin-laden macrophages in a background of red blood cells. Histology of the olive-green mossy lesions revealed dense sheets of hemosiderin-laden macrophages and rare foci of endometriosis.

    Peritoneal exudate cells (PEC), obtained after the rejection of EL4 leukemia by BALB/c mice, are much more effective in the specific in vitro destruction of 51Cr-labeled EL4 cells than are spleen, thymus, lymph node, or peripheral blood lymphocytes. The presence of a large number of effector cells at the site of graft rejection is reflected in the potent cytolytic activity seen in vitro. Effector cells temporarily lose cytolytic reactivity when treated with trypsin but regain reactivity with time. This recovery occurs in normal as well as in immune serum. The destructive reactivity of PEC is increased when macrophages are removed. The remaining population of nonadherent PEC is composed primarily of small- to medium-sized lymphocytes. Complex tissue culture media are not needed, but there is a definite requirement for serum. The required serum component is heat stable, nondialyzable, and is not consumed during the reaction. The use of an ascites allograft system made these observations possible and permitted the isolation of those host cells intimately associated with rejection. PMID:5025438

    Hemorrhagic ascites in patients with cirrhosis is described as a RBC (Red Blood cell) > 50,000/mm³ and leads to increased morbidity and mortality. Positive red blood cells at a level of less than 50,000/mm³ (10,000-50,000) may be encountered in the ascites but it is not known whether this is clinically significant or not. This study aimed to examine the outcome of hemorrhagic ascites in patients with advanced cirrhosis. Data from 329 cirrhotic patients with ascites who received paracentesis at least once due to ascites was retrospectively analyzed from the period of 2007-2013 from the Türkiye Yüksek İhtisas Hospital, Department of Gastroenterology. Patients were divided according to the number of RBC, with greater than 10,000/mm³ being described as hemorrhagic ascites, and less than 10,000/mm³ described as the normal or control group. Patient data included: number of accepted intensive unit service stays, acute kidney injury (AKI), hepatic encephalopathy (HES), model for end-liver disease (MELD) score, Child Pugh score (CPS), degree of esophageal varices, spleen size and mortality rates. Patients were defined as having hemorrhagic ascites with a RBC count greater than 10,000/mm³ in 118 (35.9%) patients and as a non-hemorrhagic ascites group with less than 10,000/mm³ in 211 (64.1%) patients. The hemorrhagic ascites group had advanced liver disease symptoms compared to the control group. Meld score in the hemorrhagic group was statistically higher than in the control group (21.5±8.3 vs. 17.3±6.6; p value: 0.001). The median value of bilirubin was 5.9 (0.45-33) in the hemorrhagic ascites group and 4.01 (0.39-33) in the non-hemorrhagic group (p value: 0.001). Using multivariate logistic regression analysis, hemorrhagic ascites was also an independent predictor of mortality (HR 2.7 1.4-6.3), with other mortality indicators being HCC (HR 3.1 1.5-6.4) and HRS (HR 2.6 1.2-5.5).

    Refractory anemia, also known as myelodysplastic syndromes, forms a group of clonal diseases characterized by cytopenias with mostly rich bone marrow. Preferentially reaching an older population, the prognosis depends on both comorbidities and characteristics of the disease, which have been grouped into a score established in 1997 ("IPSS = International Prognostic Scoring System") and revised in 2012 ("R-IPSS = Revised IPSS"). Overall survival and risk of transformation into acute nonlymphoblastic leukemia can now be estimated fairly accurately. Based on these characteristics, the treatment will be mainly supportive or will use several new molecules: growth factors, lenalidomide, 5-azacitidine, etc. A minority of patients may also benefit from allogeneic BMT or sometimes immunosuppressive therapy.

    The movement of water, electrolytes and protein across the peritoneum was studied experimentally and clinically in ascites. In the experimental and clinically in ascites. In the experimental studies, large amounts of solutions of various osmolar and colloid osmolar concentrations were infused rapidly into the peritoneal cavities of 32 dogs. In 26 of these dogs, the ureters were ligated before the experiment was begun; the other six dogs served as controls. The clinical studies were done in five patients with ascites. Tritium, 35S and RISA dilution techniques were used to study the kinetics of the different components of peritoneal fluid. Osmolarity changes were measured in plasma and peritoneal fluid by the freezing point depression method. Volume changes of peritoneal fluid were measured serially up to 24 hours for the assessment of the peritoneal absorption rate. The rate of fluid movement across the peritoneal membrane seems to be influenced, among others, by the composition of the intraperitoneal fluid, as well as by the properties of the membrane itself. An asymmetric pattern of peritoneal absorption rate of the different compositional elements of ascitic fluid was observed in this study which seems to interrelate with dynamic equilibrium which develops between ascites and the physiologic body fluid compartments. No cessation of peritoneal fluid absorption or a maximal reabsorption rate was observed in this study; nevertheless, variations in the rate of peritoneal absorption due to miscellaneous influences are possible.

    Several pathogenic processes have been implicated in the development of abdominal ascites. Portal hypertension, most usually in the context of liver cirrhosis, can explain about 75% of the cases, whereas infective, inflammatory and infiltrative aetiologies can account for the rest. In this article, we discuss the consensus best practice as published by three professional bodies for the management of ascites, spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). The aim of this study was to compare available clinical guidelines and identify areas of agreement and conflict. We carried out a review of the guidance documentation published by three expert bodies including the British Society of Gastroenterology, the European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Diseases (AASLD), as well as a wider literature search for ascites, SBP and HRS. Abdominal ultrasonography, diagnostic paracentesis and ascitic fluid cultures are recommended by all three guidelines, especially when there is strong clinical suspicion for infection. EASL and AASLD advocate the use of ascitic amylase and mycobacterial cultures/PCR when there is strong suspicion for tuberculosis and pancreatitis, respectively. Ascitic cytology can be useful when cancer is suspected and has a good diagnostic yield if performed correctly. EASL supports the use of urinary electrolytes for all patients; however, the British Society of Gastroenterology and AASLD only recommend their use for therapy monitoring. All three societies recommend cefotaxime as the antibiotic of choice for SBP and large-volume paracentesis for the management of ascites greater than 5 l in volume. For HRS, cautious diuresis, volume expansion with albumin and the use of vasoactive drugs are recommended. There appears to be good concordance between recommendations by the European, American and British guidelines for the management of ascites and the possible

    Background & Aims Hemorrhagic ascites can pose diagnostic and therapeutic dilemmas in patients with cirrhosis. We aimed at exploring the characteristics and outcomes of patients with cirrhosis and hemorrhagic ascites. Methods The records of all patients with cirrhosis and ascites, who underwent paracentesis between 2003 and 2010 at Parkland Memorial Hospital, were retrospectively reviewed. Hemorrhagic ascites was defined as an ascitic fluid red blood cell (RBC) count ≥10,000/μl. We compared each patient with 3 age- and gender-matched controls (cirrhotic patients with ascites and an ascitic RBC count <10,000/μl). Survival curves were generated using Kaplan–Meier plots and compared using the log rank test. Results 1113 cirrhotic patients underwent paracentesis; 214 (19%) had hemorrhagic ascites. Patients with hemorrhagic ascites had higher rates of spontaneous bacterial peritonitis (p <0.001), acute kidney injury (AKI, p <0.001), and were more likely to require intensive care unit (ICU)-level care (p = 0.01) compared to patients without hemorrhagic ascites. Patients with hemorrhagic ascites had a higher mortality than controls at one month (87% vs. 72%), 1 year (72% vs. 50%) and 3 years (61% vs. 41%). Using multivariate regression analysis, hemorrhagic ascites was also an independent predictor of mortality (HR 1.34, 95% CI 1.07–1.68) after adjusting for the model for end-stage liver disease score (HR 1.04, 1.03–1.05), ICU-level care (HR 2.02, 1.63–2.51) and presence of hepatocellular carcinoma (HR 2.27, 1.61–3.19). Conclusions Patients with hemorrhagic ascites had a significantly higher rate of ICU care, AKI, and mortality than patients with portal hypertension and ascites but without hemorrhagic ascites. We conclude that hemorrhagic ascites is a marker of advanced liver disease and poor outcome. PMID:23348236

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

    Eosinophilic gastroenteritis (EGE) is a rare condition characterized by eosinophilic infiltration of the gastrointestinal tract. Depending on the dominant layer of infiltration it is classified into three types namely, mucosal, muscularis and subserosal. The most uncommon variant is the subserosal type characterized by primarily subserosal disease, eosinophilic ascites and peripheral hypereosinophilia. The clinical features are non-specific with history of atopic predisposition and allergy. Endoscopic biopsy is frequently non-diagnostic due to an uninvolved gastrointestinal mucosa rendering its diagnosis a challenge. The mainstay of diagnosis is peripheral hypereosinophilia and eosinophil-rich ascitic fluid on diagnostic paracentesis. Oral steroid therapy is usually the first line of treatment with dramatic response. Due to a propensity for relapse, steroid-sparing therapy should be considered for relapses of EGE. We report a case of subserosal EGE with diagnostic clinical features and treatment response and review the current strategy in the management of eosinophilic ascites. PMID:27721930

Visual diagnosis was highly accurate in patients with tuberculous peritonitis but only moderately accurate in those with carcinomatosis and liver disease. When the laparoscopic findings were compared with histological and microbiological results visual diagnosis was found to be the most accurate diagnostic method. Laparoscopy may readily be used in rural hospitals for diagnosing ascites. PMID:3160432

    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.

    Although the factors involved in cirrhotic ascites have been studied for a century, a number of observations are not understood, including the action of diuretics in the treatment of ascites and the ability of the plasma-ascitic albumin gradient to diagnose portal hypertension. This communication presents an explanation of ascites based solely on pathophysiological alterations within the peritoneal cavity. A quantitative model is described based on experimental vascular and intraperitoneal pressures, lymph flow, and peritoneal space compliance. The model's predictions accurately mimic clinical observations in ascites, including the magnitude and time course of changes observed following paracentesis or diuretic therapy. PMID:22453061

    The use of paracentesis has recently been reproposed as a safe and effective alternative to diuretics for management of ascites. We have investigated the clinical and biochemical effects of large-volume paracentesis in 19 cirrhotics with tense ascites, and the relative changes in the hormones involved in sodium and water renal handling. Plasma renin activity (PRA), aldosterone (PA), and arginine vasopressin (AVP) levels and conventional liver and renal function tests were measured before and after 1, 2, and 7 days after the paracentesis. No complications were observed, but patients regained 37% of the weight lost after 1 wk. Percent weight regained was significantly and directly correlated with PA concentration measured before the paracentesis. No changes were recorded after paracentesis in biochemical and clinical data, except for a significant drop in diastolic blood pressure. No changes in AVP levels were observed. A significant increase in PA occurred after paracentesis, with a maximum peak after 48 h. The increase in PA was not accompanied by changes in PRA, but was associated with a reduction of urinary sodium excretion. A relevant fraction of body aldosterone was confined to the ascitic fluid. We conclude that the clinical results of a large-volume paracentesis can be predicted in part on the basis of PA measurement, and that removal of ascites is followed by an increase of PA of uncertain origin and effectiveness.

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

    Background The behavior of tumor cells is influenced by the composition of the surrounding tumor environment. The importance of ascites in ovarian cancer (OC) progression is being increasingly recognized. The characterization of soluble factors in ascites is essential to understand how this environment affects OC progression. The development of cytokine arrays now allows simultaneous measurement of multiple cytokines per ascites using a single array. Methods We applied a multiplex cytokine array technology that simultaneously measures the level of 120 cytokines in ascites from 10 OC patients. The ascites concentration of a subset (n = 5) of cytokines that was elevated based on the multiplex array was validated by commercially available ELISA. The ascites level of these 5 cytokines was further evaluated by ELISA in a cohort of 38 patients. Kaplan-Meier analysis was used to assess the association of cytokine expression with progression-free survival (PFS) in this cohort. Results We observed a wide variability of expression between different cytokines and levels of specific cytokines also varied in the 10 malignant ascites tested. Fifty-three (44%) cytokines were not detected in any of the 10 ascites. The level of several factors including, among others, angiogenin, angiopoietin-2, GRO, ICAM-1, IL-6, IL-6R, IL-8, IL-10, leptin, MCP-1, MIF NAP-2, osteprotegerin (OPG), RANTES, TIMP-2 and UPAR were elevated in most malignant ascites. Higher levels of OPG, IL-10 and leptin in OC ascites were associated with shorter PFS. IL-10 was shown to promote the anti-apoptotic activity of malignant ascites whereas OPG did not. Conclusion Our data demonstrated that there is a complex network of cytokine expression in OC ascites. Characterization of cytokine profiles in malignant ascites may provide information from which to prioritize key functional cytokines and understand the mechanism by which they alter tumor cells behavior. A better understanding of the cytokine network is

    Massive ascites after living donor liver transplantation (LDLT), defined as small-for-size graft syndrome, is a risk factor for a poor prognosis. Few studies have reported factors associated with ascites and the relevant outcome after LDLT. Data from 413 adult patients that underwent LDLT were retrospectively analyzed. Recipient age, preoperative albumin level, Child-Pugh score, preoperative ascites, graft volume, intraoperative blood loss, and duration of warm ischemic time and the anhepatic phase were significantly associated with the total amount of ascites between postoperative day (POD) 1 and POD14. Multivariate analysis identified preoperative ascites, intraoperative blood loss, and duration of anhepatic phase as factors. Massive ascites (ascitic fluid discharge >1,000 ml/day on POD14 after LDLT) occurred in 200 (48.4%) patients, and mild ascites occurred in the remaining 213 patients. Daily changes in the ascites volume differed between the two groups. Nevertheless, massive ascites itself did not have a critical impact on the patient short- and long-term outcomes when properly managed with rigorous diuretics and albumin administration. Massive ascites is frequent after LDLT; however, the impact of it could be minimized with an appropriate management. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

  17. Approaches to refractory epilepsy

    PubMed Central

    Engel, Jerome

    2014-01-01

    Epilepsy is one of the most common serious neurological conditions, and 30 to 40% of people with epilepsy have seizures that are not controlled by medication. Patients are considered to have refractory epilepsy if disabling seizures continue despite appropriate trials of two antiseizure drugs, either alone or in combination. At this point, patients should be referred to multidisciplinary epilepsy centers that perform specialized diagnostic testing to first determine whether they are, in fact, pharmacoresistant, and then, if so, offer alternative treatments. Apparent pharmacoresistance can result from a variety of situations, including noncompliance, seizures that are not epileptic, misdiagnosis of the seizure type or epilepsy syndrome, inappropriate use of medication, and lifestyle issues. For patients who are pharmacoresistant, surgical treatment offers the best opportunity for complete freedom from seizures. Surgically remediable epilepsy syndromes have been identified, but patients with more complicated epilepsy can also benefit from surgical treatment and require more specialized evaluation, including intracranial EEG monitoring. For patients who are not surgical candidates, or who are unwilling to consider surgery, a variety of other alternative treatments can be considered, including peripheral or central neurostimulation, ketogenic diet, and complementary and alternative approaches. When such alternative treatments are not appropriate or effective, quality of life can still be greatly improved by the psychological and social support services offered by multidisciplinary epilepsy centers. A major obstacle remains the fact that only a small proportion of patients with refractory epilepsy are referred for expert evaluation and treatment. PMID:24791078

    2015-01-01

    Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of stomach contents into the esophagus causes troublesome symptoms, esophageal injury, and/or complications. Use of proton pump inhibitors (PPI) remains the standard therapy for GERD and is effective in most patients. Those whose symptoms are refractory to PPIs should be evaluated further and other treatment options should be considered, according to individual patient characteristics. Response to PPIs could be total (no symptoms), partial (residual breakthrough symptoms), or absent (no change in symptoms). Patients experiencing complete response do not usually need further management. Patients with partial response can be treated surgically or by using emerging endoscopic therapies. Patients who exhibit no response to PPI need further evaluation to rule out other causes. PMID:25274499

    The goal of this study was to identify clinical and imaging variables that are associated with an unfavorable outcome during the 30 days following transjugular intrahepatic portosystemic shunt (TIPS) placement. Fifty-four consecutive patients with liver cirrhosis (Child-Pugh 6-13, Model for End-stage Liver Disease 7-26) underwent TIPS placement for refractory ascites (n=25), recurrent or uncontrolled variceal bleeding (n=23) or both (n=6). Clinical, biological and imaging variables including type of stent (covered n=40; bare-stent n=14), presence of spontaneous portosystemic shunt (n=31), and variations in portosystemic pressure gradient were recorded. Early severe complication was defined as the occurrence of overt hepatic encephalopathy or death within the 30days following TIPS placement. Sixteen patients (30%) presented with early severe complication after TIPS placement. Child-Pugh score was independently associated with complication (HR=1.52, P<0.001). Among the imaging variables, opacification of spontaneous portosystemic shunt during TIPS placement but before its creation was associated with an increased risk of early complication (P=0.04). The other imaging variables were not associated with occurrence of complication. Identification of spontaneous portosystemic shunt during TIPS placement reflects the presence of varices and is associated with an increased risk of early severe complication.

    Malignant ascites is an abnormal accumulation of fluid in the peritoneal cavity of patients with intraperitoneal cancer dissemination. This clinical condition could represent the terminal evolution of a lethal disease and could influence the prognosis, severely impairing the patients' quality of life. Treatment options include a multitude of different procedures with limited efficacy and some degree of risk; diuretics, paracentesis, peritoneo-venous shunts and intraperitoneal biologic agents like anti-VEGF molecules, metalloproteinase inhibitors and immunomodulators are included. None of these approaches have been established as a standard of care because of their low efficacy or severe side effects. The last two decades saw the emergence of cytoreductive surgery with hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) as a viable therapeutic approach resulting in an effective cure against refractory malignant ascites. The following describes our experiences with 3 cases together with a literature review.

    An ascites syndrome was induced in 17 to 28 per cent of specific pathogen-free (SPF) Light Sussex (LSX) chickens given a low protein (16 per cent crude protein) high calcium (3.5 per cent calcium) layer crumble feed on two separate occasions 6 months apart. Affected chickens had increased right ventricular weight as a proportion of either total heart weight or live-weight at 3 weeks of age, compared with non-affected LSX chickens on the same feed, thus indicating right ventricular hypertrophy. The incidence of ascites was not increased by infection with avian nephritis virus, nor by limited cold-stress during brooding. It was not produced in LSX chickens given other feeds, nor in SPF Rhode Island Red chickens.

    Eleven patients with ascitic cirrhosis and eleven patients without liver disease received 200 mg of cimetidine orally and intravenously. Plasma concentrations of cimetidine were analysed by high pressure liquid chromatography. No differences were observed in cimetidine half-life (2.53 +/- 0.63 and 2.33 +/- 0.40 h) between the two groups. Cimetidine clearance was diminished by about 30 p 100 in cirrhotic patients (0.426 +/- 0.138 vs. 0.649 +/- 0.163 l/h/kg). The apparent volume of distribution was also significantly diminished (1.50 +/- 0.44 vs. 2.14 +/- 0.55 l/kg) in patients with cirrhosis and ascites.

    AIM: To study the patients with low gradient ascites in hospitals of Guilan Province (northern Iran). METHODS: Patients admitted in hospitals of Guilan Province with low gradient ascites from 1993 to 2000 were enrolled in the study. Serum and ascitic fluid albumin levels were determined by biochemical reactions. The serum-ascitic albumin gradient (SAAG) less than 1.1 g/dL was considered low. Statistical analysis was performed with SPSS 9.0 software and P<0.05 was considered statistically significant. RESULTS: Of the 148 patients enrolled in the study, 72 (48.6%) were males and 76 (51.4%) were females with a mean age of 59.03±13.54 years. Tuberculous peritonitis was the most frequent cause of low gradient ascites in 68 (45.9%). Other most frequent causes were cancer in 62 (41.9%), nephrotic syndrome in 9 (6%), pancreatitis in 6 (4%). Peritoneal cancer was found in 22 (35%), ovarian and gastric cancers were found in 14 (22.5%) and 12 (19.3%), respectively. All of which were the causes of ascites. The mean SAAG was 0.68±0.19 g/dL. The mean serum and ascitic fluid albumin concentrations were higher in tuberculous patients (P<0.006), but lactate dehydrogenase (LDH) level was higher in cancer patients (P<0.0001). In peritoneal tuberculosis, mean ascitic glucose concentration was significantly lower than other patients (P<0.0001). CONCLUSION: Tuberculosis should be considered in all patients with low gradient ascites especially in developing countries (like Iran), as the first cause of ascites. In the approach to patients with low gradient ascites, ascitic fluid glucose, and LDH level are useful indicators for decision making. PMID:15818749

    Refractories are used in furnaces and boilers that process steel, cement, or glass as well as incinerators that operate at high temperatures. A variety of binders is used when refractories are manufactured. In this chapter, the use of phenolic resin as a binder for refractories is described. There are several factors that support the use of phenolic resins in comparison to other refractory binders. These include the following: 1. Both adhesion and green body strength are high.

    Ascites, in 20% of cases, is not linked to liver cirrhosis. The pathophysiology is most often different. The understanding of these pathophysiological mechanisms can lead to etiologic diagnosis. The diagnostic approach is mainly based on the biological study of ascites, especially protein concentration and albumin gradient between serum and ascites. In Western countries, tumors and heart diseases are the predominant causes, while developing countries are mainly concerned by infectious diseases, among which tuberculosis is the leading cause. Other uncommon causes must be recognized, as ascites may be the presenting feature of the disease. Their knowledge will facilitate the therapeutic approach.

    Broiler chickens are intensively selected for productive traits. The management of these highly productive animals must be optimal to allow their full genetic potential to be expressed. If this is not done, inefficient production and several metabolic diseases such as ascites become apparent. The causes of the ascites are multifactorial but diet and, particularly, interactions between diet, other environmental and genetic factors play an important role. The relatively high heritability estimates for ascites-related traits and the significance of maternal genetic effects for most of the traits indicate that direct and maternal genetic effects play an important role in development of the ascites syndrome. An imbalance between oxygen supply and the oxygen required to sustain rapid growth rates and high food efficiencies causes ascites in broiler chickens. Because of the relationship to oxygen demand, ascites is affected and/or precipitated by factors such as growth rate, altitude (hypoxia) and environmental temperature. 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. Manipulation of the diet composition and/or feed allocation system can have a major effect on the incidence of ascites. Optimization of the house temperature and ventilation in cold weather seem helpful practices to decrease ascites incidence.

    Refractory hepatic encephalopathy (HE) remains a major cause of morbidity in cirrhosis patients. Large spontaneous portosystemic shunts (SPSSs) have been previously suggested to sustain HE in these patients. We aimed to retrospectively assess the efficacy and safety of patients treated with embolization of large SPSSs for the treatment of chronic therapy-refractory HE in a European multicentric working group and to identify patients who may benefit from this procedure. Between July 1998 and January 2012, 37 patients (Child A6-C13, MELD [Model of Endstage Liver Disease] 5-28) with refractory HE were diagnosed with single large SPSSs that were considered eligible for embolization. On a short-term basis (i.e., within 100 days after embolization), 22 out of 37 patients (59.4%) were free of HE (P < 0.001 versus before embolization) of which 18 (48.6% of patients overall) remained HE-free over a mean follow-up period of 697 ± 157 days (P < 0.001 versus before embolization). Overall, we noted improved autonomy, decreased number of hospitalizations, and severity of the worst HE episode after embolization in three-quarters of the patients. Logistic regression identified the MELD score as strongest positive predictive factor of HE recurrence with a cutoff of 11 for patient selection. As to safety, we noted one major nonlethal procedure-related complication. There was no significant increase in de novo development or aggravation of preexisting varices, portal hypertensive gastropathy, or ascites. This multicenter European cohort study demonstrated a role for large SPSSs in chronic protracted or recurrent HE and substantiated the effectiveness and safety of embolization of these shunts, provided there is sufficient functional liver reserve.

    Correlations between tumour markers in ascitic fluid and serum were investigated to determine whether ascitic fluid analysis had any diagnostic advantage over serum in 91 adults with ascites (55 malign; 36 benign). Serum and ascitic fluid were analysed for carcinoembryonic antigen (CEA), cancer antigen (CA) 125, CA19.9, CA72.4, CA15.3, alpha-fetoprotein (AFP) and cytokeratin-19 fragment (CYFRA). The tumour markers were skewed between the groups so were logarithmically transformed. Correlations between serum and ascitic fluid were tested using Pearson's correlation coefficient. Serum and ascitic fluid levels of CEA, CA125, CYFRA and AFP in the malign group were statistically different and CEA, CA19.9, CA5.3, CYFRA and AFP were statistically different in the benign group. For both groups, all tumour markers were highly correlated in serum and ascitic fluid, with the exception of CYFRA in the malign group. These results indicate that, where malignant ascites is suspected, analysing tumour markers in ascitic fluid does not have any advantage over serum analysis.

    To determine the predictive value of physical signs for ascites, we compared the results of physical examination with those of abdominal sonography in 90 men in hospital with liver disease. The positive predictive values of shifting dullness and prominent fluid waves were low (51% and 73%). We divided the patients into two groups: those with prolonged prothrombin times (72% prevalence of ascites by sonogram), and those with normal prothrombin times (15% prevalence). In patients with prolonged prothrombin times, a prominent fluid wave had a very high positive predictive value for ascites (96%). Many patients with prolonged prothrombin times had ascites despite negative physical signs. In contrast, in those with normal prothrombin times, both shifting dullness and prominent fluid waves were usually falsely positive. Patients with normal prothrombin times and no shifting dullness rarely (2%) had ascites. The predictive value of physical signs for ascites depends on the prevalence of ascites in groups of patients that are examined. The prothrombin time is a useful index for identifying inpatients with a high or low prevalence of ascites and the predictive value of physical signs is enhanced by interpreting them in combination with a patient's prothrombin time.

    Ehrlich ascites cells, in which replication units at the beginning of the S phase started and grew synchronously, were obtained by the following protocol: (1) selection of G{sub 1} cells by zonal centrifugation, (2) hypoxia for 12 h, (3) reaeration, (4) addition of cycloheximide (30 {mu}M) within the first minute after reoxygenation. Studies on the effectiveness of the different steps revealed: (i) G{sub 1} cells reoxygenated after 12 h of hypoxia traverse two succeeding cell cycles high synchronously. This was shown by monitoring the thymidine incorporation rate, the thymidine pulse-labeling index, and the mitotic index. (ii) Cycloheximide, like hypoxia, suppresses replicon initiation in Ehrlich ascites cells without interfering with DNA chain growth and DNA maturation. The reversibility of the suppression is less complete than in the case of hypoxia. This was shown by DNA fiber autoradiography and by analyzing the length distribution of pulse- or pulse/pulse-chase-labeled daughter DNA in alkaline sucrose gradients. The alkaline sedimentation patterns of daughter-strand DNA, pulse labeled immediately after the cycloheximide addition at the end of the elaborated protocol and 1 and 2 h later, indicated synchronous initiation and growth of a homogeneous population of DNA molecules to replicon-sized lengths.

    Liver cirrhosis is a serious and potentially life-threatening condition. This life-threatening condition usually arises from complications of cirrhosis. While variceal bleeding is the most acute and probably best studied, several other complications of liver cirrhosis are more insidious in their onset but nevertheless more important for the long-term management and outcome of these patients. This review summarizes the topics discussed during the UEG-EASL Hepatology postgraduate course of the United European Gastroenterology Week 2013 and discusses emergency surgical conditions in cirrhotic patients, the management of hepatic encephalopathy, ascites and hepatorenal syndrome, coagulation disorders, and liver cancer.

    The CFB maintenance manager has to make rapid-fire decisions regarding refractory maintenance during short or unscheduled turnarounds. This presentation offers a hands-on approach to expedient refractory failure analyses with specific repair recommendations. Photographs of most typical CFB refractory failures and their structural repairs are discussed. The most reliable repairs can be expected by using the latest state-of-the-art refractory materials and installation techniques. Refractory materials are consumable; therefore minor repairs should always be conducted at the first opportunity; this will preclude future major repairs. During a short or unscheduled outage, major repairs should be confined to the specific structural repair site; the removal of good, serviceable refractory is unnecessary under these conditions.

    Malignant ascites (MA) can be managed with paracentesis, diuretics, shunt-systems, chemotherapy, and targeted therapies. Some treatments are ineffective; others are associated with complications, involve inpatient procedures, or are not cost-effective. Postoperative lymphocysts (LCs) are managed with inpatient drainage and sclerotherapy or surgery. We tested the use of a vascular catheter in the management of symptomatic MA and LC. Fifty-five patients with primary or recurrent cancers with ascites or LCs were managed for symptom relief. A central venous 14-Ga 16-cm catheter (Arrow) was inserted into the abdominal cavity or LC, followed by drainage. The catheter was safely inserted with ultrasound guidance in 43 patients with MA (39 with ovarian cancer: 9 before primary cytoreduction, 30 with recurrence; 4 non-gynecological cancers), and 12 patients with LCs (10 retroperitoneal, 2 bilateral inguinal). All procedures were performed in the outpatient department under local anesthesia, without insertion-related complications. Within a mean of 30 days after catheter placement (range: 7-90 days), no grade 3 infection, peri-drain leakage, or self-removal was noted. In three patients with recurrent ovarian mucinous ascites and one patient with an inguinal LC, some drain obstruction was noted. In cases before primary cytoreduction for ovarian cancer, drainage enabled better nutritional and anesthiological outcomes. Patients with chronic ascites were able to self-monitor the amount of evacuated fluid. Twelve patients whose ascites were drained had chemotherapy at the time, and they reported better well-being, and we estimated better performance status. LC drainage followed by sclerotherapy enabled symptom control and LC radical treatment. The use of the vascular catheter is safe, easy, and cost-effective in the management of symptomatic MA and LC.

    Avid renal sodium and water retention among other mechanisms produce ascites in patients with cirrhosis. The main guidelines recommend sodium intake reduction in order to counteract this complication. However, some randomized controlled trials have suggested a lack of benefit with a sodium-restricted over an unrestricted diet, and even an increase in ascites and renal complications has been reported. There are no systematic reviews addressing this question. A systematic review protocol has been designed and will be reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). We will search for randomized controlled trials evaluating a salt-restricted versus unrestricted regime in patients with cirrhosis and ascites in EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials. We will also try to identify literature by reviewing reference list of included studies and relevant reviews, screening main conference proceedings, and searching for unpublished and ongoing trials in the World Health Organization (WHO) International Clinical Trials Registry Platform. Two researchers will independently undertake selection of studies, data extraction, and assessment of the quality of included studies. We will estimate pooled risk ratios for dichotomous data and the mean difference or standardized mean difference for continuous outcomes. A random effect model will be used for meta-analyses. Data synthesis and other analyses will be conducted using RevMan software. no ethics approval is considered necessary. Results of this study will be disseminated via peer-reviewed publications and social networks Sodium restriction is a widely accepted coadjuvant therapy for ascites; however, this indication is based primarily on expert recommendations. As far as we know, this will be the first systematic review assessing the effects of a sodium-restricted diet for ascites in cirrhotic patients. Our systematic review will aim to

    The clinical manifestations of amyloidosis depend on the type of insoluble protein as well as the location of amyloid deposits in tissues or organs. In the gastrointestinal tract, the small intestine is the most common site of amyloid deposits, whereas peritoneal involvement and ascites are rare. We report on a case of ascites due to peritoneal amyloidosis. A 65-year-old patient was admitted to our institution due to anasarca and pulmonary congestion, mimicking heart failure. We started the patient on diuretics and vasodilators. Despite improvement in pulmonary congestion and peripheral edema, his ascites was not reduced. Echocardiogram revealed restrictive cardiomyopathy and a speckle-tracking pattern suggestive of cardiac amyloidosis. Subcutaneous and peritoneal biopsies revealed amyloidosis. Amyloidosis is rare in the peritoneum and is usually asymptomatic. Ascites occurs in only 20% of patients with peritoneal amyloidosis. We searched PubMed using "ascites" and "amyloidosis" and identified only eight case reports of amyloidosis with ascites. Physicians should be particularly careful in heart failure and anasarca cases when ascites is disproportional or not responsive to diuretic treatment. To date, there is no specific treatment for peritoneal amyloidosis.

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

    Ascites caused by hypothyroidism is rare and the pathogenesis is unclear. Several reports have presented cases of progressive ascites with hypothyroidism and elevated tumor markers. We report a 31-year-old female case with massive ascites and elevated serum CA 125 concentrations. The patient had no typical feature of hypothyroidism except an accumulation of ascitic fluid which showed elevated total protein concentration and a high serum-ascites albumin gradient (SAAG). There was no finding of malignancy. Following thyroid hormone replacement, the ascites was completely resolved accompanied by reduced concentrations of serum CA125. In general, primary hypothyroidism with ascites presents with coexisting massive pericardial or pleural effusion. The massive ascites and increased serum CA125 concentrations may have led us to make the incorrect diagnosis of ovarian malignancy. The evaluation of thyroid function is useful to determine the pathology of high-protein ascites or elevated tumor markers, and ascites may be treatable by thyroid replacement therapy.

    Thoracic duct injury is a rare but serious complication following surgery of the neck or chest that leads to uncontrolled chyle leak. Conventional management includes drainage, nutritional modification, or aggressive surgical interventions such as thoracic duct ligation, flap coverage, fibrin glue, or talc pleurodesis; few successful medical therapeutics are available. We report a case of a high-output chylothorax refractory to aggressive medical and surgical interventions. Chyle output decreased substantially after initiating midodrine, an α1-adrenergic agonist that causes vasoconstriction of the lymph system, reducing chyle flow. This case report suggests that midodrine may be a novel therapeutic for refractory chyle leaks.

This article focuses specifically on refractory CRS, meaning those patients who have failed medical and surgical management already. The options available in the management of refractory CRS depend on the personnel, equipment, and instrumentation available in the office setting; surgeon experience; and patient suitability and tolerability. This article provides readers with possible procedural options that can be done in their clinics with indications, patient selection, potential complications, and postoperative considerations.

    The onset of diarrhoea and cramp-like abdominal pain following consumption of an identified food type is not an uncommon presentation to many practitioners. However, when it fails to settle and is associated with unusual features both on examination and on initial work-up, then a more complex diagnostic and therapeutic conundrum needs to be considered. We report on such a case where the onset of diarrhoea was associated with ascites and peripheral eosinophilia. A variety of causes including parasitic and tuberculous infection were excluded. A diagnosis of eosinophilic enteritis was made based on definite criteria, and appropriate management was instituted. In this report we discuss the diagnostic criteria and some of the proposed pathophysiologic theories in order to explain this unusual disease process.

    Cytoreductive surgery for epithelial ovarian cancer (EOC) is the cornerstone of multimodal therapy and considered as a high-risk surgery because of extensive multivisceral procedures. In most patients, ascites is present, but its impact on the surgical and clinical outcomes is unclear. One hundred nineteen patients undergoing surgical cytoreduction because of EOC between 2005 and 2008 were included. All surgical data and the individual tumor pattern were collected systematically based on a validated documentation tool (intraoperative mapping of ovarian cancer) during primary surgery. The amount of ascites was determined at the time of surgery, and 3 groups were classified (no ascites [NOA, n = 56], low amount of ascites [< 500 mL, n = 42], and high amount of ascites [HAS > 500 mL, n = 21]). Group NOA compared with HAS showed less transfusions of packed red blood cells (median [quartiles], 0 [0-2] vs 0 [0-2] vs 3 [1-4] U; P < 0.001) and fresh frozen plasma (median [quartiles], 0 [0-2] vs 0 [0-4] vs 2 [2-6] U; P < 0.001). In addition, in patients with ascites, noradrenaline was administered more frequently and in higher doses. The postoperative length of stay in the intensive care unit was significantly shorter in the NOA versus the group with low amount of ascites and HAS (median [quartiles], 1 [0-1] vs 1 [0-2] vs 2 [1-5] days; P < 0.001). The hospital length of stay is extended in HAS compared with that in NOA (median [quartiles], 16 [13-20] vs 17 [14-22] vs 21 [17-41] days; P = 0.004). Postoperative complications were increased in patients with ascites at the time of surgery (P = 0.007). The presence of a high amount of ascites at cytoreductive surgery because of EOC is associated with higher amounts of blood transfusions, whereas the length of hospital stay and the postoperative intensive care unit treatment are significantly prolonged compared with those of patients without ascites.

    The goal of the proposed project is to provide expertise and facilities for the high temperature mechanical properties characterization of refractory materials which are of interest to the US DOE`s Office of Industrial Technologies Advanced Industrial Materials Project. Initially the project would establish dedicated refractory testing facilities which would be capable of generating representative engineering creep and high temperature modulus of elasticity (MOE) data to a temperature of 3300{degrees}F (1815{degrees}C) in ambient air. The generated engineering creep and MOE data would serve R&D requirements of refractories-manufacturers and its glass-manufacturer end-users and designers. The relevance of this effort to the refractory and glass-making industries would be ensured by coordinating the research activities through a membership with Alfred University`s Center for Glass Research (CGR) Satellite Center at the University of Missouri-Rolla (UMR), an NSF Center. Valid engineering creep and high temperature MOE data currently do not exist for almost all commercial refractories. Refractory end-users such as glass-manufacturers require such data for efficient and economical design of their various glass-melting furnace superstructures (e.g., furnace crowns). Refractories in glass production furnaces may be subjected to extreme temperatures as high as 3200{degrees}F (1760{degrees}C). With the simultaneous imposition of mechanical and thermal stresses, creep deformation of the refractory material will assuredly occur as a consequence. Designers must ensure that the structural integrity is maintained, so these high temperature deformations must be considered for successful glass furnace superstructure design. These criteria can only be satisfied with the utilization of representative engineering creep and high temperature MOE data for the refractory materials that are chosen for the design of the refractory superstructures.

    Whilst ascites is a common presenting complaint in patients with decompensated chronic liver disease and disseminated malignancy, in Crohn's disease however, it is exceptionally rare. We describe a patient with no prior history of inflammatory bowel or liver disease, presenting with rapid onset gross ascites and scrotal swelling. Further investigations revealed severe hypoalbuminemia and transudative ascitic fluid with normal other liver function tests and a negative liver screen. Computed tomography revealed widespread ascites and pleural effusions with no features of malignancy or portal hypertension, and a small bowel barium series showed features of fistulating small bowel Crohn's disease. An ileo-colonoscopy confirmed the presence of terminal ileal inflammatory stricture. The patient's clinical condition and serum albumin improved with a combination of diuretics, elemental diet, antibiotics and oral 5-aminosalicylic acid therapy.

    A 50-year-old male presented with intractable ascites due to systemic mastocytosis. The diagnosis of systemic mastocytosis was established by histology of the bone marrow which showed mast cell infiltration and fibrosis. Ascites was related to portal hypertension which was documented by esophageal varices at endoscopy and by an increase of wedged-free hepatic venous pressure gradient. Liver biopsy disclosed dense fibrosis of hepatic arterial and portal venule walls, resulting in complete obstruction of some portal radicles. Peliosis hepatis and fibrous deposits in the walls of hepatic venules were also present. Because of intractable ascites and significant malnutrition, a portacaval shunt was performed which cleared ascites and dramatically improved the general condition of the patient.

    Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract with an estimated prevalence of one in 100,000. The typical presentation consists of vague gastrointestinal symptoms with the mucosal involvement of the digestive system. Rarely, it presents as eosinophilic ascites. We report the case of a 22-year-old female who presented with acute onset abdominal pain and ascites. The laboratory studies were remarkable for eosinophilia and the ascitic fluid demonstrated high eosinophilic counts. Push enteroscopy with biopsy supported the diagnosis of eosinophilic gastroenteritis, with likely serosal involvement. Other differential diagnoses were excluded. A prednisone taper along with dietary treatment was initiated. We report complete resolution of symptoms two weeks following the initiation of therapy. Nine months later, she remains asymptomatic without recurrence of ascites. PMID:27843730

    Ascites is a major complication of liver cirrhosis which carries a poor prognosis. Diuretics are used in treatment of ascites in addition to salt restriction. Monitoring of diuretic response can be achieved by measurement of 24 hours urinary sodium. This study evaluated the accuracy of using spot urinary sodium/potassium ratio as a reliable alternative to 24 hours urinary sodium in assessment of dietary sodium compliance in patients with liver cirrhosis receiving diuretics. Fifty patients presented with liver cirrhosis and ascites were divided into 2 groups: GI 14 (28%) patients diuretic resistant with 24 hours urinary sodium < 78 mEq) and GII 36 (72%) patients diuretic sensitive with 24 hours urinary sodium > 78 mEq. The results showed highly significant correlation between 24 hours urinary sodium and spot urine sodium/potassium ratio with sensitivity 87.5% specificity 56% and accuracy 70% at cutoff point of 1.8.

Cross-sectional comparative study. Pathology Department, Bannu Medical College, Bannu, KPK, from January 2012 to December 2013. Paracentesis of 20 ml of ascitic fluid tapped from cirrhotic patients with SBPwas 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. In 105 cases of ascitic fluid analyses, 27 (25.72%) had positive ascitic fluid culture whereas 78 (74.28%) 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). Direct bedside inoculation of ascitic fluid by BACTEC culture bottle method has better yield as compared to conventional culture method.

Conclusions: Amyloidosis is rare in the peritoneum and is usually asymptomatic. Ascites occurs in only 20% of patients with peritoneal amyloidosis. We searched PubMed using “ascites” and “amyloidosis” and identified only eight case reports of amyloidosis with ascites. Physicians should be particularly careful in heart failure and anasarca cases when ascites is disproportional or not responsive to diuretic treatment.

    A refractory duodenal ulcer was arbitrarily defined as one that had failed to heal completely after treatment with cimetidine 1 g daily for three months. Of 66 patients with refractory duodenal ulcer, healing eventually occurred in 37 patients, after treatment for an average of 7.4 months. But 28 patients did not heal despite treatment for an average of 9.4 months; and one patient defaulted. In 41 patients the daily dose of cimetidine was increased to 2 g: the ulcers in 31 patients healed. In eight patients the daily dose was increased to 3 g and healing occurred in four patients. Eighteen patients required admission on 22 occasions because of severe symptoms despite treatment. Nine patients underwent surgery but in five the results were poor. Differences in clinical and endoscopic features between refractory and non-refractory ulcer patients were small. Acid and pepsin secretion were similar and gastrin concentrations normal. Blood levels of the drug and suppression of acid secretion were both satisfactory. Identification of refractory ulcer patients at the start of treatment was therefore not possible. Refractoriness could occur at any time during the course of the disease, previous treatment with cimetidine often having resulted in rapid healing, but subsequent relapses were also usually refractory. The cause of refractoriness remains unknown and the rather poor results of surgery in this series suggests that optimal management of these patients remains to be determined. Refractoriness probably indicates a changed natural history of the disease and in some patients a more poor prognosis. PMID:6428982

    OBJECTIVES: To identify the occurrence and the causes of platelet refractoriness in oncohematologic patients. INTRODUCTION: Platelet refractoriness (unsatisfactory post-transfusion platelet increment) is a severe problem that impairs the treatment of oncohematologic patients and is not routinely investigated in most Brazilian services. METHODS: Forty-four episodes of platelet concentrate transfusion were evaluated in 16 patients according to the following parameters: corrected count increment, clinical conditions and detection of anti-platelet antibodies by the platelet immunofluorescence test (PIFT) and panel reactive antibodies against human leukocyte antigen class I (PRA-HLA). RESULTS: Of the 16 patients evaluated (median age: 53 years), nine (56%) were women, seven of them with a history of pregnancy. An unsatisfactory increment was observed in 43% of the transfusion events, being more frequent in transfusions of random platelet concentrates (54%). Platelet refractoriness was confirmed in three patients (19%), who presented immunologic and non-immunologic causes. Alloantibodies were identified in eight patients (50%) by the PIFT and in three (19%) by the PRA-HLA. Among alloimmunized patients, nine (64%) had a history of transfusion, and three as a result of pregnancy (43%). Of the former, two were refractory (29%). No significant differences were observed, probably as a result of the small sample size. CONCLUSION: The high rate of unsatisfactory platelet increment, refractoriness and alloimmunization observed support the need to set up protocols for the investigation of this complication in all chronically transfused patients, a fundamental requirement for the guarantee of adequate management.

    Decompensated liver cirrhosis (LC), a life-threatening complication of chronic liver disease, is one of the major indications for liver transplantation. Recently, mesenchymal stem cell (MSC) transfusion has been shown to lead to the regression of liver fibrosis in mice and humans. This study examined the safety and efficacy of umbilical cord-derived MSC (UC-MSC) in patients with decompensated LC. A total of 45 chronic hepatitis B patients with decompensated LC, including 30 patients receiving UC-MSC transfusion, and 15 patients receiving saline as the control, were recruited; clinical parameters were detected during a 1-year follow-up period. No significant side-effects and complications were observed in either group. There was a significant reduction in the volume of ascites in patients treated with UC-MSC transfusion compared with controls (P < 0.05). UC-MSC therapy also significantly improved liver function, as indicated by the increase of serum albumin levels, decrease in total serum bilirubin levels, and decrease in the sodium model for end-stage liver disease scores. UC-MSC transfusion is clinically safe and could improve liver function and reduce ascites in patients with decompensated LC. UC-MSC transfusion, therefore, might present a novel therapeutic approach for patients with decompensated LC.

    The safety of nonselective β-blockers (NSBBs) in advanced cirrhosis has been questioned. We used data from three satavaptan trials to examine whether NSBBs increase mortality in cirrhosis patients with ascites. The trials were conducted in 2006-2008 and included 1198 cirrhosis patients with ascites followed for 1 year. We used Cox regression to compare all-cause mortality and cirrhosis-related mortality between patients who did and those who did not use NSBBs at randomization, controlling for age, gender, Model for End-Stage Liver Disease score, Child-Pugh score, serum sodium, previous variceal bleeding, cirrhosis etiology, and ascites severity. Moreover, we identified clinical events predicting that a patient would stop NSBB treatment. At randomization, the 559 NSBB users were more likely than the 629 nonusers to have a history of variceal bleeding but less likely to have Child-Pugh class C cirrhosis, hyponatremia, or refractory ascites. The 52-week cumulative all-cause mortality was similar in the NSBB user and nonuser groups (23.2% versus 25.3%, adjusted hazard ratio = 0.92, 95% confidence interval 0.72-1.18), and NSBBs also did not increase mortality in the subgroup of patients with refractory ascites (588 patients, adjusted hazard ratio = 1.02, 95% confidence interval 0.74-1.40) or in any other subgroup. Similarly, NSBBs did not increase cirrhosis-related mortality (adjusted hazard ratio = 1.00, 95% confidence interval 0.76-1.31). During follow-up, 29% of initial NSBB users stopped taking NSBBs, and the decision to stop NSBB treatment marked a sharp rise in mortality and coincided with hospitalization, variceal bleeding, bacterial infection, and/or development of hepatorenal syndrome. This large and detailed data set on worldwide nonprotocol use of NSBBs in cirrhosis patients with ascites shows that NSBBs did not increase mortality; the decision to stop NSBB treatment in relation to stressful events may have added to the safety.

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

    Increased metabolic rates, pulmonary hypertension and cardiac dysfunction are the most important features of the ascites syndrome in broiler chickens. However, the mechanism of cell injury causing the pathogenesis of the syndrome is not clearly understood. Our study aimed to examine the generation of hydroxyl radicals (OH*) in broiler chickens experiencing ascites. The hundred and fifty 1-d-old chickens were purchased from a local hatchery and reared in an open poultry house for 46 d. They were divided at random into three groups and ascites was induced in two groups by exposing them to low temperature or administration of triiodothyronine (T(3)). The third group served as control and was reared normally. Haematological, biochemical and pathological tests were used to determine the incidence of ascites: including total red blood cell (RBC), packed cell volume (PCV), release of alanine transaminase (ALT) and aspartate transaminase (AST) and ratio of right ventricular weight to total ventricular weight (RV/TV). A salicylate hydroxylation method was used to examine the generation of hydroxyl radicals (OH*) in treated groups. TWo hydroxylated salicylic acid metabolites, 2,3- and 2,5-dihydroxy benzoic acid (2,3- and 2,5-DHBA), were measured by HPLC to detect the generation of OH*. An ascites syndrome was observed in T(3) and low-temperature treated groups, as shown by necropsy changes and increases in f RBC, PCV, ALT, AST and the ratio of RV/TV. Concentrations of 2,3- and 2,5-DHBA were increased in groups experiencing ascites compared to control group. It is suggested that reactive oxygen species that is OH* ions, may be involved in the pathogenesis of the ascites syndrome in broiler chickens.

    Different macromolecules were administered intraperitoneally to stimulate formation of protein-rich ascitic fluid in rodents. Stimulatory effect of plant lectins depended on the attachment to cell surface carbohydrates, Canavalia ensiformis (ConA) lectin was used in the majority of experiments. The time course of ConA-induced ascites was divided into an early (up to 4 h) and a late (from 6 h on) phase, with a transitional period between the two. Water and protein accumulation showed parallel time courses: volume of the ascitic fluid peaked at around 3 h, and fibrin threads appeared after 6 h. Viscosity of the ascitic fluid and its supernatant increased with time, reaching maximal fibrinogen concentration at around 16 h. Peritoneal permeability, followed by pleural and pericardial effusions, was elicited only by lectins that form soluble complexes with serum glycoproteins, whereas the effect of serum-precipitating lectins was restricted to the peritoneum. Macromolecules with serial positive charges (e.g., polylysine or polyethyleneimine) enhanced peritoneal permeability by ionic interactions with cell surface molecules. Viscosity of the polycation-induced ascitic fluid did not tend to increase with time and corresponded to the early phase of the ConA-induced ascites. Polyglutamate, a polyanionic macromolecule, inhibited the effect of polycations, but not that of ConA. The most efficient stimulatory macromolecules appear to induce ascites by noncovalent cross-linking of cell surface glycoproteins or glycosaminoglycans or both. A similar mechanism may operate in the maintenance of basal secretion to prevent eventual desiccation. Noncovalent cross-linking appears to be a common denominator of both basal and enhanced permeability.

    MircoRNA’s (miR) have been recognised as important modulators of gene expression and potential biomarkers. However, they have been rarely investigated in bio fluids apart from blood. We investigated the association of miR-125b and miR-155 with complications of cirrhosis. Ascites was prospectively collected from patients with cirrhosis undergoing paracentesis at our department. miR’s were determined in the supernatant using qPCR and normalized by SV-40. Clinical parameters were assessed at paracentesis and during follow-up. 76 specimens from 72 patients were analysed. MiR’s were not associated to age, sex or aetiology of cirrhosis. MiR-125b levels differed between patients with low and high MELD score, and miR-125b levels showed an inverse correlation to serum creatinine (r2 = −0.23; p = 0.05). MiR-155 was elevated in patients with spontaneous bacterial peritonitis (SBP) (n = 10; p = 0.04). MiR-155 levels differed between patients with and without 30-day survival (p = 0.02). No association of ascites levels of investigated miR’s to size of varices, episodes of gastrointestinal bleeding or hepatorenal syndrome was observed. While miR-125b levels in ascites seem to be associated with liver and renal dysfunction, miR-155 might be implicated in local immune response in SBP. PMID:28074870

  8. Changes in gut bacterial populations and their translocation into liver and ascites in alcoholic liver cirrhotics

    Background The liver is the first line of defence against continuously occurring influx of microbial-derived products and bacteria from the gut. Intestinal bacteria have been implicated in the pathogenesis of alcoholic liver cirrhosis. Escape of intestinal bacteria into the ascites is involved in the pathogenesis of spontaneous bacterial peritonitis, which is a common complication of liver cirrhosis. The association between faecal bacterial populations and alcoholic liver cirrhosis has not been resolved. Methods Relative ratios of major commensal bacterial communities (Bacteroides spp., Bifidobacterium spp., Clostridium leptum group, Enterobactericaea and Lactobacillus spp.) were determined in faecal samples from post mortem examinations performed on 42 males, including cirrhotic alcoholics (n = 13), non-cirrhotic alcoholics (n = 15), non-alcoholic controls (n = 14) and in 7 healthy male volunteers using real-time quantitative PCR (RT-qPCR). Translocation of bacteria into liver in the autopsy cases and into the ascites of 12 volunteers with liver cirrhosis was also studied with RT-qPCR. CD14 immunostaining was performed for the autopsy liver samples. Results Relative ratios of faecal bacteria in autopsy controls were comparable to those of healthy volunteers. Cirrhotics had in median 27 times more bacterial DNA of Enterobactericaea in faeces compared to the healthy volunteers (p = 0.011). Enterobactericaea were also the most common bacteria translocated into cirrhotic liver, although there were no statistically significant differences between the study groups. Of the ascites samples from the volunteers with liver cirrhosis, 50% contained bacterial DNA from Enterobactericaea, Clostridium leptum group or Lactobacillus spp.. The total bacterial DNA in autopsy liver was associated with the percentage of CD14 expression (p = 0.045). CD14 expression percentage in cirrhotics was significantly higher than in the autopsy controls (p = 0

    As many as 50% of end-stage cancer patients will develop ascites and associated symptoms, including pain, tiredness, nausea, depression, anxiety, drowsiness, loss of appetite, dyspnea, perceived abdominal bloating, and immobility. Abdominal massage may stimulate lymph return to the venous system and reduce ascites-related symptoms. The purpose of this study was to test the effect of abdominal massage in reducing these symptoms and reducing ascites itself as reflected in body weight. For a randomized controlled design using repeated measures, a sample of 80 patients with malignant ascites was recruited from gastroenterology and oncology units of a medical center in northern Taiwan and randomly assigned to the intervention or the control group. A 15-minute gentle abdominal massage, using straight rubbing, point rubbing, and kneading, was administered twice daily for 3 days. The control group received a twice-daily 15-minute social interaction contact with the same nurse. Symptoms and body weight were measured in the morning for 4 consecutive days from pre- to post-test. In generalized estimation equation modeling, a significant group-by-time interaction on depression, anxiety, poor wellbeing, and perceived abdominal bloating, indicated that abdominal massage improved these four symptoms, with the greatest effect on perceived bloating. The intervention had no effect on pain, tiredness, nausea, drowsiness, poor appetite, shortness of breath, mobility limitation, or body weight. Abdominal massage appears useful for managing selected symptoms of malignant ascites.

    Epithelial ovarian cancer (EOC) is worldwide the sixth most lethal form of cancer occurring in women. More than one third of ovarian patients have ascites at the time of diagnosis and almost all of them have it when recurrence occurs. Although its effect on tumor cell microenvironment remains poorly understood, its presence is correlated with bad diagnosis. In previous studies, we proposed a novel glycan-based biomarker for the diagnosis of EOC, which showed an improved sensitivity and specificity at any stage of the disease and an improved discrimination between malignant and benign ovarian tumors. In this work, we report for the first time the N-glycome profiles of ascitic fluid from primary serous EOC patients and compare them with the serum N-glycomes of the same patients as well as of healthy controls. N-Glycans were digested from equivalent amount of ascites and serum from 18 EOC patients and from serum of 20 age-matched controls and measured by MALDI-TOF-MS. Ascites N-glycome showed increased antennarity, branching, sialylation and Lewis(X) motives compared to healthy serum. In addition, a correlation was established between ascites volume and degree of sialylation.

    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.

    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.

    The isolation of Candida spp. in ascites of cirrhotic patients is an uncommon situation in clinical practice. Factors that have been associated with increased susceptibility to primary fungal peritonitis are exposure to broad-spectrum antibiotics and immunosuppression, a typical situation of these patients. We report seven episodes of Candida spp. isolation in ascites of cirrhotic patients detected in our hospital during the past 15years.

    A rational approach to the diuretic therapy of ascites is proposed. Fifty-five patients were classified according to their ability to excrete sodium and free water. Patients with a high urinary sodium excretion can be treated by low sodium intake alone. In most patients with a low sodium excretion but high free water clearance, distal diuretics (spironolactone or triamterene) with a low sodium diet will relieve ascites. Patients with low values for sodium excretion and free water clearance also have poor glomerular filtration rate and only a few of these will respond to diuretic therapy. PMID:1234341

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

    A small subset of celiac disease (CD) patients becomes refractory to a gluten-free diet with persistent malabsorption and intestinal villous atrophy. Diagnosis of this condition defined as refractory celiac disease (RCD) is made after exclusion of other small bowel diseases with villous atrophy. RCD has been subdivided into two subgroups according to the normal or abnormal phenotype of intraepithelial lymphocytes. Whereas normal RCD is hardly distinguishable from active CD, abnormal RCD has a severe clinical presentation and a very poor prognosis. We precisely describe below the different types of RCD and propose diagnostic and therapeutic guidelines for its clinical management.

    Serum-ascites albumin gradient (SAAG) has been used in the classification of ascites for the last 20 years but it has some drawbacks. This study searches for possible correlations between ascitic fluid viscosity and the etiology of ascites, renal impairment, and length of ICU stay. The study was conducted in Zagazig University Hospital, Egypt. It included 240 patients with ascites due to various causes. The patients were divided into two groups: the cirrhotic ascites group, which included 120 patients, and the noncirrhotic ascites group, which included 120 patients. Ascitic patients on medical management with diuretics, antibiotics, paracentesis, and infusion of plasma or albumin were excluded.The laboratory analysis included routine investigations to detect the cause of ascites as well as specific investigations such as ascitic fluid viscosity using a falling ball viscosimeter (microviscosimeter) at 37°C. The mean ascitic viscosity of patients with SAAG at least 1.1 was 1.16±0.56, which was associated with serum creatinine 1.35±0.52 mg/dl and ICU stay of 3.3±1.2 days. In patients with SAAG less than 1.1 g/dl, the mean ascitic viscosity was 2.98±0.87, with serum creatinine 2.1±0.56 mg/dl and ICU stay of 7.1±1.3 days. Ascitic viscosity can discriminate ascites due to portal hypertension from those associated with nonportal hypertension at a cut-off value of 1.65; it can predict renal impairment in hepatic patients at a cut-off of 1.35 and long ICU stay at a cut-off of 1.995 using receiver operating characteristic analysis. Ascitic viscosity measurement is rapid, inexpensive, and requires small sample volumes. Ascitic viscosity can discriminate ascites due to portal hypertension from those associated with nonportal hypertension at a cut-off value of 1.65. It can predict renal impairment in hepatic patients at a cut-off of 1.35 and long ICU stay at a cut-off of 1.995.

    Orthotopic liver transplantation (OLT) is a treatment for end-stage liver disease. The shortage of available organs leads to the acceptance of marginal grafts, thereby increasing the risk of perioperative complications such as acute rejection, infection, and graft dysfunction Procalcitonin (PCT) has been shown to be a reliable marker for a complicated course after traumatic injury as well as in the courses of systemic inflammatory response syndrome and sepsis. The aim of our study was to evaluate PCT as an early prognostic marker for the occurrence of complication during the postoperative course after OLT. We analyzed PCT levels and clinical and paraclinical data of 32 patients who underwent 33 OLTs. The highest PCT was termed as peak-PCT. Patients were stratified into noncomplication and complication groups. Renal replacement therapy, respiratory insufficiency, postoperative bleeding, refractory ascites, pleural effusion, rejection, sepsis, and fatal outcome were defined as complications. A secondary stratification, using a peak-PCT of 5 ng/mL, was used to analyzed the risk of a complication. We also analyzed the course of PCT after OLT in each group. The peak-PCT, which occurred between the first and third postoperative day in 30 patients, was followed by halving of the value every second day. Three subjects died because of sepsis. A constantly rising PCT or a secondary rise observed in 2 patients was associated with a fatal outcome. The noncomplication group included 18 patients, 8 of them showing a peakPCT <5 ng/mL and 10 above. The complication group included 14 patients who underwent 15 transplantations; Only 1 displayed a peakPCT <5 ng/mL. When the peak-PCT was >5 ng/mL, the odds ratio of a complication was 11.2 (95% Confidence interval, 10.81-11.59; P < .025). However, not before the 7th postoperative day was the course of mean PCT levels significantly different between the complication and noncomplication groups. In transplant patients, an elevation of PCT

    The gut flora plays an important role in the pathogenesis of the complications of cirrhosis. Cirrhotic patients are prone to develop bacterial infections, mainly the 'spontaneous' infection of ascites or spontaneous bacterial peritonitis. Other complications of cirrhosis, such as variceal haemorrhage and ascites, occur mostly or solely as a consequence of portal hypertension. Portal pressure increases initially as a consequence of an increased intrahepatic resistance but, once collaterals have formed, high portal pressure is maintained by an increased splanchnic blood inflow secondary to vasodilatation. Splanchnic vasodilatation is the initiating event in the hyperdynamic circulatory state that aggravates the complications of cirrhosis. The gut flora plays a role in both the development of infections and in the hyperdynamic circulatory state of cirrhosis and, although less prominently, it also plays a role in the pathogenesis of hepatic encephalopathy. This chapter presents evidence regarding gut flora and its modification in the pathogenesis and management of these complications of cirrhosis.

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

    The University of North Dakota (UND) Chemical Engineering Department in conjunction with the UND Energy & Environmental Research Center (EERC) have initiated a program to examine the combined chemical (reaction and phase change) and physical (erosion) effects experienced by refractory materials under slagging coal gasification conditions. The goal of this work is to devise a mechanism of refractory loss under these conditions. The controlled-atmospheric dynamic corrodent application furnace (CADCAF) was utilized to simulate refractory/slag interactions under dynamic conditions that more realistically simulate the environment in a slagging coal gasifier than any of the static tests used previously by refractory manufacturers and researchers. High-alumina and high-chromia refractory bricks were tested using slags obtained from two solid fuel gasifiers. Testing was performed at 1475 C in a reducing atmosphere (2% H{sub 2} in N{sub 2}) The CADCAF tests show that high-chrome refractories have greater corrosion resistance than high-aluminum refractories; coal slag readily diffuses into the refractory through its grain boundaries; the refractory grains are more stable than the matrix in the tests, and the grains are the first line of defense against corrosion; calcium and alkali in the slag are more corrosive than iron; and silicon and calcium penetrate the deepest into the refractory. The results obtained from this study are preliminary and should be combined with result from other research programs. In particular, the refractory corrosion results from this study should be compared with refractories removed from commercial gasifiers.

    Ascites in systemic lupus erythematosus (SLE) is rarely massive, and either accompanies the typical manifestations of active disease or results from nephrotic syndrome, protein-losing enteropathy, constrictive pericarditis, and conditions unrelated to lupus. Marked ascites has been attributed to chronic lupus peritonitis, characterized by the insidious onset of massive, painless ascites and unrelated to disease activity. Regardless of the etiology, ascites typically has a gradual onset and occurs after a diagnosis of SLE has been made. We describe a young woman presenting with the rapid development of massive ascites as the initial manifestation of SLE.

    Slagging coal gasifiers suffer corrosive attack on the refractory liner and these interactions were thermochemically simulated. The slag is observed to penetrate the refractory, which complicates modeling the phase behavior of the slag-penetrated interior of the refractory. A simple strategy was adopted such that step-wise changes in composition with decreasing slag content were assumed to account for the compositional changes as slag penetrates the refractory. The thermochemical equilibrium calculations following this strategy typically yielded three solution phases as well as the stoichiometric crystalline phases AlPO4 and Ca3(PO4)2 depending on composition/penetration. Under some conditions a slag liquid miscibility gap exists such that two slag liquids co-exist.

    Erythromelalgia is characterized by intense burning pain, erythema, and heat in affected areas after precipitating factors such as warm temperature or stress. It is refractory to treatment in some situations. We describe a woman with adenosquamous cell carcinoma of the lung and medically refractory erythromelalgia. The symptoms of erythromelalgia presented as refractory to any medical treatment. Due to the unresponsive nature of her condition, botulinum toxin type A (onabotulinumtoxin A) was injected over both of her cheeks, periodically for six cycles. Her symptoms responded dramatically to subcutaneous and intradermal injection of botulinum toxin type A. Repetitive injection demonstrated consistent and reproducible responses, and the efficacy was maintained for approximately 1 month. No adverse effects or complications were noted. Botulinum toxin type A might be safe and effective as an alternative treatment for refractory erythromelalgia, but further large-scale studies are required. Copyright © 2013.

A patient with ascites in the anterior subphrenic space had an apparent cold lesion in the left lobe of the liver. Ultrasonography demonstrated a normal left lobe and localized the fluid collection.

    Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent fever and peritoneal and pleural inflammation. It is an inherited disorder commonly found in Armenians, Turks, Arabs, Balkans, and Jews originating from North African countries. A small amount of peritoneal fluid collection can be observed during peritoneal attacks in patients with Familial Mediterranean fever, but chronic ascites has been described rarely in these patients. A 42-year-old female patient was admitted to our clinic in June 2010 with fever, severe abdominal pain and abdominal distention that had continued for one month. There was no family history of periodic fevers or abdominal pain. We could not find any cause for ascites, including tuberculosis. A diagnosis of Familial Mediterranean fever was suspected based on the clinical findings and her family history. She was screened for mutations causing Familial Mediterranean fever, and when found to be homozygous for M694V, treatment with colchicine was initiated. After treatment, the amount of ascites decreased, and relief of symptoms was confirmed during a follow-up. In conclusion, because Familial Mediterranean fever is common in our country, it should be considered in the differential diagnosis of patients with ascites of unknown etiology in populations where hereditary inflammatory disease is endemic.

    Status epilepticus (SE) is an important neurological emergency. It is defined as seizures lasting for 5 minutes or more or recurrent seizures without recovery of consciousness to baseline between the attacks. Refractory SE (RSE) is defined as SE persisting despite sufficient dose of benzodiazepines and at least one antiepileptic drug (AED), irrespective of time. Super refractory SE (SRSE) is defined as SE that continues for 24 hours or more after the use of anesthetic therapy, including cases that recur on weaning of the anesthestic agent. RSE occurs in 23%-48% of the patients and SRSE in approximately 22% of the patients with SE. In general, RSE occurs in patients with new-onset seizures rather than in patients with chronic epilepsy. The etiology of RSE in developing countries is dominated by central nervous system (CNS) infections and head injury compared to stroke and drug withdrawal in the developed countries. The treatment of RSE and SRSE is not evidence based. Following benzodiazepines, the second line antiepileptic drugs include sodium valproate, phenytoin, levetiracetam, and anesthetic drugs such as midazolam, phenobarbital, and propofol. Most intravenous anesthetic drugs produce hypotension and respiratory suppression; therefore, patients with RSE are managed in intensive care units (ICUs). In RSE patients, electroencephalogram (EEG) burst suppression with interburst interval of 2-20 s or even flat EEG has been tried. Recently, concerns have been raised on the safety of burst suppression in RSE and SRSE. The paucity of ICUs in developing countries limits the use of these management protocols. There is a need to explore intravenous AEDs with safer cardiovascular and respiratory profile for the management of SE.

    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.

    Chronic plantar fasciitis is a major health care problem worldwide and affects nearly 10% of the US population. Although most cases resolve with conservative care, the numerous treatments for refractory plantar fasciitis attest to the lack of consensus regarding these cases. The emerging goals for this condition are a minimally invasive percutaneous intervention that is safe, effective, and well-tolerated and has minimal morbidity and a low complication rate. We conducted a prospective study in which patients were allowed either to continue with noninvasive treatment or to undergo focal aspiration and partial fasciotomy with an ultrasonic probe. This is the first report of a plantar fascia partial release guided by ultrasonic energy delivered by a percutaneously inserted probe under local anesthesia. The procedure appears to be a safe, effective, well-tolerated treatment for a condition that is refractory to other options.

    Neurostimulation procedures like vagus nerve stimulation (VNS) and deep brain stimulation have been used to treat refractory epilepsy and other neurological disorders. While holding promise, they are invasive interventions with serious complications and adverse effects. Moreover, their efficacies are modest with less seizure free. Acupuncture is a simple, safe, and effective traditional healing modality for a wide range of diseases including pain and epilepsy. Thalamus takes critical role in sensory transmission and is highly involved in epilepsy genesis particularly the absence epilepsy. Considering thalamus serves as a convergent structure for both acupuncture and VNS and the thalamic neuronal activities can be modulated by acupuncture, we propose that acupuncture could be a promising therapy or at least a screening tool to select suitable candidates for those invasive modalities in the management of refractory epilepsy.

    Status epilepticus, a serious, life-threatening emergency characterized by prolonged seizure activity, occurs most commonly in pediatric patients. Although initial therapies with agents such as diazepam, phenytoin, or phenobarbital generally terminate seizure activity within 30-60 minutes, patients with refractory status epilepticus (RSE) lasting longer require additional intervention. High-dose pentobarbital has been the most commonly prescribed agent for the management of RSE in children; however, midazolam has emerged as a new treatment option. This review compares the use of midazolam with pentobarbital in published reports of pediatric RSE. Both drugs effectively terminated refractory seizure activity, although pentobarbital use was complicated by hypotension, delayed recovery, pneumonia, and other adverse effects. Midazolam use was effective and well tolerated, affirming its value in pediatric RSE management.

    Though efficient acid suppression with proton pump inhibitors (PPIs) remains the mainstay of treatment of gastroesophageal reflux disease (GERD), some of the patients showed refractory response to PPIs, necessitating further intervention. After increasing dose of PPIs and other kinds of pharmacological intervention adopting prokinetics or others, variable endoscopic treatments are introduced for the treatment of these refractory cases. The detailed introduction regarding endoscopic treatment for GERD is forwarded in this review article. Implantation of reabsorbable or synthetic materials in the distal esophagus was tried in vain and is expelled from the market due to limited efficacy and serious complication. Radiofrequency energy delivery (Stretta) and transoral incisionless fundoplication (EsophyX) are actively tried currently. PMID:23767031

    Recurrent pericarditis is a troublesome complication of idiopathic acute pericarditis and occurs more frequently in pediatric patients after cardiac surgery (postpericardiotomy syndrome). Conventional treatment with nonsteroidal antiinflammatory drugs, corticosteroids, and colchicine is not always effective or may cause serious adverse effects. There is no consensus, however, on how to proceed in those patients whose disease is refractory to conventional therapy. In such cases, human intravenous immunoglobulin, immunosuppressive drugs, and biological agents have been used. In this report we describe 2 patients with refractory recurrent pericarditis after cardiac surgery who were successfully treated with 3 and 5 monthly high-dose (2 g/kg) intravenous immunoglobulin until resolution of the effusion. Our experience supports the effectiveness and safety of this therapy. Copyright © 2014 by the American Academy of Pediatrics.

    Abstract Malignant ascites (MA) is most commonly observed in patients scheduled for epithelial ovarian cancer (EOC) surgery and is supposed as a major risk factor promoting perioperative hemodynamic deterioration. We aimed to assess the hemodynamic consequences of MA on systemic circulation in patients undergoing cytoreductive EOC surgery. This study is a predefined post-hoc analysis of a randomized controlled pilot trial comparing intravenous solutions within a goal-directed algorithm to optimize hemodynamic therapy in patients undergoing cytoreductive EOC surgery. Ascites was used to stratify the EOC patients prior to randomization in the main study. We analyzed 2 groups according to the amount of ascites (NLAS: none or low ascites [<500 mL] vs HAS: high ascites group [>500 mL]). Differences in hemodynamic variables with respect to time were analyzed using nonparametric analysis for longitudinal data and multivariate generalized estimating equation adjusting the analysis for the randomized study groups of the main study. A total of 31 patients in the NLAS and 16 patients in the HAS group were analyzed. Although cardiac output was not different between groups suggesting a similar circulatory blood flow, the HAS group revealed higher heart rates and lower stroke volumes during surgery. There were no differences in pressure-based hemodynamic variables. In the HAS group, fluid demands, reflected by the time to reindication of a fluid challenge after preload optimization, increased steadily, whereas stroke volume could not be maintained at baseline resulting in hemodynamic instability after 1.5 h of surgery. In contrast, in the NLAS group fluid demands were stable and stroke volume could be maintained during surgery. Clinically relevant associations of the type of fluid replacement with hemodynamic consequences were particularly observed in the HAS group, in which transfusion of fresh frozen plasma (FFP) was associated to an improved circulatory flow and reduced

    The objective of this paper was to study the anti-Ehrlich ascites carcinoma effect of purified toad venom extract and its mechanism. Mouse model of Ehrlich ascites carcinoma was established with cisplatin as the control to observe the inhibitory effect of purified toad venom extract on malignant peritoneal effusion in mice. The results showed that compared with the control group, ascites volume, number of tumour cells and tumour cell viability decreased and ascites inhibition rate reached over 50% in each treatment group, and with the increase of the dose, incidence of ascites showed a downward trend. The number of tumour cells in ascites and tumour cell viability in the purified toad venom high-dose group were lower than those of the cisplatin group. Compared with the model group, survival time was prolonged in varying degrees in the purified toad venom groups and cisplatin group. The study concluded that purified extract of toad venom has an anti-Ehrlich ascites carcinoma effect.

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

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

    Ascites is one of the main features of liver decompensation in cirrhosis, and it is considered to be a dynamic process. In this study, we aimed to (1) measure the reabsorption rate of ascites; (2) evaluate whether these findings were related to features of ascites, hemodynamics, and serum measurements; and (3) examine morphologic changes in the diaphragm of cirrhotic patients. In all, 42 cirrhotic patients with ascites were enrolled in the study to comprise our study group. Using the dextran 70 test, patient ascites volumes and reabsorption rates were measured. Biopsies from the peritoneal side of the diaphragm were also processed for scanning electron microscopy and lymphatic immunohistochemical studies from the cirrhotic patients and control cadavers. The mean ascites reabsorption rate was 4.5 +/- 4.5 (0.18-14.6) mL/min, which correlated significantly with the calculated ascites volume (r = 0.75, P < 0.001). The mean ascites viscosity was 1.07 +/- 0.07 (0.99-1.17) centipoise, which demonstrated a high degree of negative correlation with the ascites reabsorption rate (r = -0.77, P < 0.001). Patients with a history of spontaneous bacterial peritonitis had significantly lesser ascites reabsorption rates than patients without this particular history. The size of lymphatic stomata in scanning electron microscopy depictions was increased, and lymphatic lacunae were dilated in immunohistochemical studies in the cirrhotic patients with ascites. However, these findings were not uniform in every cirrhotic patient with ascites. The volume and viscosity of ascites seem to influence its reabsorption rate. Additionally, previous episodes of spontaneous bacterial peritonitis may be responsible for the decreased ascites reabsorption rates observed in certain patient populations.

    It is expected that cell-free and concentrated ascites reinfusion therapy (CART) will relieve the symptoms caused by ascites. To date, however, no report of objective changes in patients' symptoms has been published. We have therefore evaluated symptom management by CART. From April 2011 to July 2012, 37 patients at our hospital, most of whom had malignancies, received CART. Symptom severity was evaluated in each patient 24 h before and after the first CART procedure using a numerical rating scale for abdominal tension and the Japanese version of the M. D. Anderson Symptom Inventory (MDASI-J) for various symptoms. CART significantly improved the scores for abdominal tension and the symptom and interference scores of the MDASI-J within 24 h of the procedure. The abdominal tension scores decreased from 7.19 to 3.81 (p < 0.001), the symptom scores of the MDASI-J decreased from 4.73 to 2.75 and the interference scores of the MDASI-J decreased from 7.05 to 5.12. Detailed investigation revealed many symptoms, including fatigue and gastric symptoms, which are the usual targets of paracentesis, as well as general symptoms. No significant correlation between improved scores and the amount of reinfused protein or ascites removed was observed. Patients experienced no severe adverse event. Among the 37 patients receiving CART, various symptoms related to malignant ascites, especially fatigue, improved within the 24-h period following CART. Factors that ameliorate these symptoms remain to be elucidated.

    The high growth rate (GR) of contemporary broilers is driven by high rate of feed intake and metabolism. Because of the consequent high oxygen demand, especially when coupled with exposure to high altitude or low temperatures, some broilers fail to regulate oxygen supply and develop the ascites syndrome (AS), which leads to mortality and economic losses. Because of the association between high GR, oxygen demand, and AS, it has been suggested that AS is induced by high GR. If true, further GR enhancement should be avoided because it will increase the proportion of AS-susceptible individuals in contemporary stocks. An alternative hypothesis claims that AS is associated with high actual GR only because the latter increases oxygen demand and that there are genetically AS-resistant broilers that do not develop AS, even when exhibiting high GR. These hypotheses were tested in trials in the years 2002 and 2006, with broilers differing in potential GR: contemporary fast-growing commercial lines and an experimental line derived from commercial broilers in 1986, and (in 2002 only) divergently selected AS-susceptible and AS-resistant lines. A protocol of high-challenge ascites-inducing conditions (AIC) from d 19 was used to distinguish between AS-susceptible and AS-resistant individuals and to determine their GR up to this age. The difference in AS incidence between the divergent lines (93.9 vs. 9.5%) was not explained by the 5% difference in their GR, thus indicating a lack of genetic correlation. In the broiler lines, AS incidence was 31 and 47% in 2002 and 2006, respectively, and 32% in the 1986 slow-growing line. Most broilers that remained healthy under the high-challenge AIC exhibited the same early GR and BW as those that later developed AS. These results, and the relatively high incidence of AS in the slow-growing line, indicate that there is very little, if any, direct genetic association between AS and genetic differences in potential GR, and suggest that AS

    The rapid growth of modern broilers is associated with enhanced appetite and high metabolic rate and, consequently, high O(2) demand. Ascites syndrome (AS) develops in individuals that fail to fully supply the increasing demand for O(2) in their bodies under ascites-inducing conditions (AIC) such as high altitude or low temperatures. The tendency of broilers to develop AS is heritable, but efficacious selection against AS susceptibility (without affecting the normal expression of other important traits) requires identification of indirect selection criteria. In the present study, divergent AS-susceptible (AS-S) and AS-resistant (AS-R) lines were developed to confirm the heritability of AS and to facilitate future detection of criteria for indirect selection against AS susceptibility. The base population consisted of 85 sire families with a mean of 73 progeny per sire, reared in a commercial broiler house under low-challenge AIC (cold environment and pelleted feed). Chicks dying with AS manifestations were designated AS-susceptible, whereas the surviving birds were designated AS-resistant. By the end of the trial (d 48), AS mortality had accumulated to 17.2%, but AS incidence per family (%ASF) ranged from 0 to 49%, with a high heritability (0.57). Parents of 7 families with very high %ASF produced the first generation (S(1)) of the AS-S line, and parents of 7 families with very low %ASF produced the S(1) of the AS-R line. The S(1) males and females reproduced generation S(2) of the selected lines, whereas additional S(1) males were tested under high-challenge AIC (individual cages, cool wind, and pelleted feed). Progeny testing under this high-challenge AIC, followed by sib selection, was repeated in generations S(2) and S(3), resulting in a divergence of 86.6% in the incidence of AS between the AS-S (91.3%) and AS-R (4.7%) lines. The rapid genetic divergence, and family analysis of %ASF suggested that a single or few major genes are responsible for the difference

    Introduction: Myasthenia gravis (MG) is an antibody mediated autoimmune neuromuscular disorder characterized by fatigable muscle weakness. A proportion of myasthenia gravis patients are classified as refractory due to non responsiveness to conventional treatment. This retrospective study was done to evaluate clinical profile, epidemiological, laboratory, and features of patients with MG and mode of management using rituximab and complications. Methods: Data of myasthenia gravis patients admitted or presented to outpatient department (previous medical records) with MG between January 2008 and January 2016 were included. A total of 512 patients fulfilled the clinical and diagnostic criteria of myasthenia gravis of which 76 patients met the diagnostic certainty for refractory myasthenia gravis and were evaluated. Results: Out of 76 refractory MG patients, 53 (69.73%) patients fulfilled all the three defined criteria. The median age of onset of the refractory MG group was 36 years with a range of 27-53 years. In our study 25 patients (32.89%) belonged to the age group of 21-30 years. Anti-MuSK antibodies were positive in 8 non-refractory MG patients (2.06%) and 36 refractory MG patients (47.36%). Mean HbA1C was found to be 8.6±2.33. The dose of administered prednisone decreased by a mean of 59.7% (p=3.3x10(-8)) to 94.6% (p=2.2x10(-14)) after the third cycle of rituximab treatment. Conclusion: The refractory MG patients are most commonly female with an early age of onset, anti-MuSK antibodies, and thymomas. Refractory MG patients have higher prevalence and poor control (HbA1C >8%) of diabetes mellitus and dyslipidemia probably due to increased steroid usage. Rituximab is very efficient in treatment of refractory MG with adverse effects being low.

    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.

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

There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED), i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs) and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits. PMID:24791086

    Insulin-like growth factor-1 (IGF-1) and C-reactive protein (CRP) are produced mainly by the liver; the output of these markers in response to inflammatory processes may be affected in patients with hepatic dysfunction. This may explain the differences in IGF-1 and CRP values in patients with non-portal and portal hypertension ascites. We aimed to evaluate serum and ascitic fluid IGF-1 and CRP as diagnostic markers in the differential diagnosis of benign and malignant ascites. In this prospective study, 398 consecutive patients with ascites were included. Serum and ascitic fluid levels of IGF-1 and CRP were measured using an enzyme-linked immunosorbent assay. Patients were divided into group 1, due to benign ascites (n = 324), and group 2, due to malignant ascites (n = 74). Serum and ascitic IGF-1 were significantly increased in malignant ascites than benign ascites group [305 ± 65.7 ng/mL vs 95 ± 53.8 ng/mL; P < 0.001 and 288 ± 54.7 ng/mL vs 83.2 ± 36.7 ng/mL; P < 0.001], respectively. Serum and ascitic CRP were significantly higher in malignant ascites than benign ascites patients [12.8 ± 6.3 mg/mL vs 6.1 ± 4.9 mg/mL; P < 0.001 and 5.1 ± 2.2 mg/mL vs 1.6 ± 1.3 mg/mL; P < 0.001], respectively. At a cutoff value of 309.4 ng/mL and 7.8 mg/mL, serum IGF-1 and CRP had (95.1%, 81%) sensitivity and (88.6%, 75.5%) specificity for detecting malignant ascites [area under the curve: 0.932, 0.845], respectively. At a cutoff value of 291.6 ng/mL and 2.6 mg/mL, ascitic IGF-1 and CRP had (94.6%, 84%) sensitivity and (83.2%, 80.3%) specificity for detecting malignant ascites (area under the curve: 0.911, 0.893) correspondingly. Elevated serum and ascitic fluid IGF-1 and CRP levels were associated with malignant ascites. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Background Most patients with advanced ovarian cancer and some patients with advanced endometrial cancer need repeated drainage for malignant ascites. Guidelines to advise those involved in the drainage of ascites are usually produced locally and are generally not evidence-based but mainly based on clinicians’ anecdotal evidence and experience. To discover whether there are ways of managing drains that have been demonstrated to improve the efficacy and quality of the procedure is key in making recommendations which could improve the quality of life (QOL) for women at this critical period of their lives. Objectives To evaluate the benefit and harms of different practices in the management of drains for malignant ascites in the care of women with advanced or recurrent gynaecological cancer. The review aimed to evaluate the evidence regarding the following questions; How long should the drain stay in place? Should the volume of fluid drained be replaced intravenously? Should the drain be clamped to regulate the drainage of fluid? Should any particular vital observations be regularly recorded? Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 1, 2009, Cochrane Gynaecological Cancer Group Trials Register, MEDLINE1950 to February Week 3 2009, Embase 1980 to 2009 Week 8 2009. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of review articles and contacted experts in the field. Selection criteria We searched for randomised controlled trials (RCTs), quasi-RCTs and non-randomised studies that compared a range of interventions for management of multiple paracentesis in women with malignant ascites who had a confirmed histological diagnosis of gynaecological cancer. Data collection and analysis Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. No trials were found and therefore no data were analysed.

    The purpose of this article is to differentiate exudative from transudative ascites using B-mode gray-scale ultrasound histogram analysis. Sixty-two consecutive patients with ascites were prospectively studied from June 2014 through June 2015. All underwent ultrasound (US) and paracentesis in the radiology department. Five patients were excluded (three with hemorrhage and two with peritoneal carcinomatosis). The remaining 57 patients were divided into those with exudative and transudative ascites according to results of paracentesis. Electronically recorded US images were transferred to a workstation, and gray-scale histograms were generated. The ascites-to-rectus abdominis muscle echogenicity ratio (ARAER) was obtained from ascites adjacent to the rectus abdominis muscle. ROC curves were used to evaluate the sensitivity and specificity of this method in differentiating exudative from transudative ascites. ARAERs for exudative ascites were significantly higher than those for transudative ascites (p < 0.001). ROC was done to evaluate ARAERs for exudative ascites. The best cutoff value for ARAER histogram was 0.002. The sensitivity and specificity of ARAER were 87.5% and 79.2% (AUC = 0.843), respectively. ARAER is an easily applicable noninvasive quantitative sonographic method with high sensitivity and specificity in differentiating exudative from transudative ascites.

    To investigate the impact of ascites volume on ovarian cancer outcomes. Clinicopathologic features of a cohort of patients with ovarian cancer were obtained from a curated database at a single institution. Progression free survival (PFS) and overall survival (OS) were recorded. Ascites volume at primary surgery was dichotomized at 2000mL and comparisons for high and low volume ascites were made. Additionally, to elucidate interactions between ascites and ovarian tumor progression, we evaluated the effect of intraperitoneal administrations of murine cell-free ascites versus saline in a syngeneic mouse model of epithelial ovarian cancer. Out of 685 patients identified, 58% had ascites present at the time of initial surgery. Considering the volume of ascites continuously, each liter of ascites was associated with shorter PFS (HR=1.12, 95% CI: 1.07-1.17) and OS (HR=1.12, 95%CI: 1.07-1.17). Patients with ascites greater than the median of 2000mL had significantly shorter PFS (14.5months vs. 22.7months; p<0.001) and OS (27.7months vs. 42.9months; p<0.001). After adjusting for stage, presence of ascites was inversely associated with ability to achieve optimal cytoreductive surgery. Consistent with these correlative results in patients, intraperitoneal administrations of murine cell-free ascites accelerated ovarian cancer progression in mice. The volume of ascites at initial diagnosis of ovarian cancer correlated with worse PFS and OS. The effect of large volume on prognosis is likely to be in part related to reduced likelihood for complete resection of tumor (R0). If these findings are confirmed in independent studies, consideration should be made to add the presence of large volume ascites at diagnosis to the staging criteria for ovarian cancer.

    Ascites syndrome is a metabolic disorder in broilers. Mortality due to ascites results in significant economic losses and has a negative impact on animal welfare. It has been shown that genetic factors play a considerable role in susceptibility of birds to ascites, which offers perspectives for selection against this syndrome. The aim of the present study was to evaluate the consequences of alternative selection strategies for BW and resistance to ascites syndrome using deterministic simulation. In addition to the consequences of current selection (i.e., selection for increased BW only) alternative selection strategies including information on different ascites-related traits measured under normal or cold conditions and the consequences of having information on the underlying genes (i.e., MAS) were quantified. Five different breeding schemes were compared based on the selection response for BW, ascites susceptibility, and the rate of inbreeding. Traits investigated in the index as indicators for ascites were hematocrit value (HCT) and ratio of right ventricle to the total ventricular weight of the heart (RV:TV). The results indicated that by ignoring ascites susceptibility in the breeding goal, the gain for BW is 130 g and the birds will become more susceptible to ascites. Testing 50% of the birds under cold temperature conditions and including information of ascites related traits (HCT and RV:TV) measured under normal and cold conditions makes it possible to achieve a relatively high gain for BW (111.4 g) while controlling the genetic level for ascites susceptibility (selection response was 0). The results of scenarios including QTL information of ascites susceptibility showed that QTL information could be used very effectively in controlling ascites susceptibility.

    We present a man with refractory leg ulcers, bilateral varicosis of the lower extremities, and Buerger disease. Autoimmune work-up was negative. However, chromosome analysis showed Klinefelter syndrome (48 XXY). Ulcerative lesions of the lower extremities are a complication of Klinefelter syndrome. To date, the pathogenesis of ulcers in Klinefelter syndrome has not been clarified, but several factors, such as abnormalities of fibrinolysis and prothrombotic states, might be involved. Our present case emphasizes the importance of considering Klinefelter syndrome in the differential diagnosis of a male patient with nonhealing ulcers of the lower extremities.

    Objectives: The aims of this study were to determine the etiology, clinical features, and predictors of outcome of new-onset refractory status epilepticus. Methods: Retrospective review of patients with refractory status epilepticus without etiology identified within 48 hours of admission between January 1, 2008, and December 31, 2013, in 13 academic medical centers. The primary outcome measure was poor functional outcome at discharge (defined as a score >3 on the modified Rankin Scale). Results: Of 130 cases, 67 (52%) remained cryptogenic. The most common identified etiologies were autoimmune (19%) and paraneoplastic (18%) encephalitis. Full data were available in 125 cases (62 cryptogenic). Poor outcome occurred in 77 of 125 cases (62%), and 28 (22%) died. Predictors of poor outcome included duration of status epilepticus, use of anesthetics, and medical complications. Among the 63 patients with available follow-up data (median 9 months), functional status improved in 36 (57%); 79% had good or fair outcome at last follow-up, but epilepsy developed in 37% with most survivors (92%) remaining on antiseizure medications. Immune therapies were used less frequently in cryptogenic cases, despite a comparable prevalence of inflammatory CSF changes. Conclusions: Autoimmune encephalitis is the most commonly identified cause of new-onset refractory status epilepticus, but half remain cryptogenic. Outcome at discharge is poor but improves during follow-up. Epilepsy develops in most cases. The role of anesthetics and immune therapies warrants further investigation. PMID:26296517

    Patients with purine analogue-refractory chronic lymphocytic leukemia (CLL) have short survival and limited treatment options. Defining the best salvage strategies for this population is challenging, because limited data are available from clinical trials, and because studies have enrolled mixed populations (patients with recurrent and refractory disease or patients with refractory disease and Richter transformation). Moreover, patients with refractory CLL have a high incidence of unfavorable molecular and clinical features, such as high-risk genomic profiles, unmutated immunoglobulin heavy-chain genes, expression of zeta-chain-associated protein kinase 70, and bulky lymphadenopathies. These patients are also severely immunosuppressed because of the underlying disease and the treatments received, and experience a high rate of infectious complications that pose an additional difficulty in selecting treatment. Despite these challenges, in parallel with better characterizations of the biologic features of refractory CLL, the number of available treatment modalities for this population has increased. Several chemoimmunotherapy combinations have been developed, and novel agents with a different mechanism of action are being investigated in clinical trials. Furthermore, allogeneic stem cell transplantation with nonmyeloablative conditioning regimens is a therapeutic strategy that is increasingly offered to patients with refractory CLL.

    The pharmacokinetics of famotidine has been investigated in ascitic cirrhotic patients. 10 decompensated cirrhotic patients were studied (9m, 1f), who had normal renal function, and six healthy control subjects (4m, 2f), matched for age, sex and weight. Each subject received on two occasions, at least four days apart, a single oral (40 mg) or intravenous dose (20 mg) of famotidine, at 21.00 h in a randomised manner. Serial blood samples were collected and famotidine in plasma was determined by a HPLC/UV method. Plasma data were subjected to non compartmental pharmacokinetic analysis. There were no statistically significant differences in pharmacokinetic parameters between the two groups after either the intravenous or oral administration of famotidine. The findings suggest that the dose of famotidine may not require any adjustment in ascitic patients without renal failure.

    Ascites can be caused by many kinds of diseases. Patients with undetermined ascites represent a diagnostic challenge. The aims of this study were to determine the diagnostic value of vascular endothelial growth factor (VEGF) in differentiation of malignant ascites from benign ascites and to investigate the clinical value of ascitic VEGF as an independent prognostic parameter. The study included 462 consecutive patients with malignant ascites and 550 patients with benign ascites, VEGF level in ascites were determined by a sandwich enzyme-linked immunosorbent assay. The survival rate was calculated by the Kaplan-Meier method and the log-rank test. Multivariate survival analysis was performed using the Cox hazards model. In our study, we found VEGF levels in malignant ascites (676.59 ± 303.86 pg/ml) were significantly higher than those in benign ascites (218.37 ± 98.15 pg/ml) (P < 0.001). Meanwhile, we also found that VEGF levels in malignant ascites from patients with ovarian cancer were higher than those with other cancers. Areas under the receiver operating characteristic (ROC) curves of ascitic VEGF was 0.940. At a cutoff value of 319.5 pg/ml, VEGF yielded a sensitivity of 89.2 % and a specificity of 88.4 %. Patients associated with the high-level VEGF value (≥613.38 pg/ml) in malignant ascites exhibited poor mean survival rates (8.3 ± 0.52 vs 15.11 ± 0.66 months, P < 0.001). In a multivariate Cox regression model, higher ascitic VEGF was an independent prognostic factor for overall survival. Planned subgroup analysis was performed for patients with tumor node metastasis (TNM) stage I. In the univariate analysis, only ascitic VEGF was associated with overall survival. VEGF was found to have a highly accurate sensitivity and specificity, suggesting that it could be considered as a new biomarker to differentiate malignant ascites from the benign one. The high level of VEGF value in malignant ascites may be used as an independent

    Cirrhosis results from progressive fibrosis and is the final outcome of all chronic liver disease. It is among the ten leading causes of death in United States. Cirrhosis can result in portal hypertension and/or hepatic dysfunction. Both of these either alone or in combination can lead to many complications, including ascites, varices, hepatic encephalopathy, hepatocellular carcinoma, hepatopulmonary syndrome, and coagulation disorders. Cirrhosis and its complications not only impair quality of life but also decrease survival. Managing patients with cirrhosis can be a challenge and requires an organized and systematic approach. Increasing physicians' knowledge about prevention and treatment of these potential complications is important to improve patient outcomes. A literature search of the published data was performed to provide a comprehensive review regarding the management of cirrhosis and its complications.

    Background Peritoneal tuberculosis is very rare in European countries. However, its incidence is increasing due to the continued immigration of people from endemic areas affected by tuberculosis. Case Report: The authors report a case of tuberculous peritonitis in a 46-year-old male patient from North Africa. The presenting symptoms of the disease were hiccups, dyspepsia, anorexia, and weight loss. Physical examination revealed an abdominal distension that suggested the presence of ascites. Subsequent investigations of ultrasound and computed tomography of the abdomen revealed the presence of massive ascites. A diagnostic laparoscopy went on to highlight a macro micronodular degeneration of the peritoneum. Histological examination showed the presence of epithelioid granulomas with typical Langhans cells with areas of caseous necrosis. The diagnosis of tuberculous peritonitis was then made, and the ascites quickly disappeared in response to the anti-mycobacterial therapy. The patient remained free of symptoms after 6 months of clinical follow-up. Conclusions: In this case the clinical diagnosis was complicated and delayed due to clinicians’ suboptimal knowledge of and experience with this disease. This case demonstrates why laparoscopy with peritoneal biopsy should be the gold standard in any clinical suspicion. PMID:23826447

    Background The diagnosis of peritonitis as a complication of cirrhosis is an important clinical problem. Objectives The aim of this study was to evaluate serum C-reactive protein levels as a diagnostic factor for spontaneous bacterial peritonitis (SBP) in child patients with liver disease. Methods In this study, 150 children diagnosed with liver disease and ascites upon admission to Nemazee Teaching Hospital (Shiraz, Iran) were examined. Patients were divided into spontaneous bacterial peritonitis and sterile ascetic fluid groups according to the PMN count ≥ 250/mm3 in the ascetic fluids. Routine laboratory tests were conducted and quantitative C-reactive protein (CRP) levels were measured for all of the patients. Accuracy, sensitivity, and specificity of CRP was evaluated for diagnosis of SBP. Results Of 150 cirrhotic patients, 109 patients presented without SBP (52.29% male, mean age: 5.02 ± 4.49 years) and 41 patients presented with SBP (51.21% male, mean age: 4.71 years). Cell counts, protein levels, albumin levels, and lactate dehydrogenize (LDH) levels of the ascetic fluid and serum samples in the SBP group were higher than the rates for those without SBP (P < 0.05(. The mean ± SD of CRP in the SBP group (36.89 ± 23.43) increased significantly compared to the rate among those without SBP (21.59 ± 15.43, P = 0.001). The percentages for sensitivity and specificity of CRP, the diagnosis of SBP based on the PMN count ≥ 250/mm3, and cultured ascites were 69.23%, 90.25%, 88.43%, and 84.32%, respectively. The areas under the curve of CRP for SBP based on the PMN count ≥ 250/mm3 and cultured ascites was 0.94 (CI 95%: 0.90 to 0.96) and 0.85 (CI 95%: 0.84 to 0.92), respectively (P < 0.001). Conclusions Our study showed that CRP is a marker with high sensitivity and specificity for the diagnosis of SBP in cirrhotic children. PMID:27795726

    Background In the cases of ascitis, it is essential to determine their origin using the parameters obtained by the cytological and biochemical examinations. The aim of this study was to evaluate the usefulness of different biochemical markers and the number of cells in the differential diagnosis of ascitic fluid (AF). Methods One hundred ninety-one cases of AF were studied, who were admitted to the hospital from January 01, 2009 to December 31, 2014. One hundred fifty-two of them were included in the analysis, and the remaining 39 were excluded because they had more than one associated pathology, clotted or hemolyzed. Results The more frequent etiologies of AF were the cirrhosis (29%), the infections (22%) and the neoplasies (19%). Other pathologies reached 16%. Cutoff > 300 cells/mm3 detected the 78% of exudates. The AF/serum (S) of aspartate aminotransferase (AST) (> 0.5), lactate dehydrogenase (LDH) (> 0.6), proteins (PT) (> 0.5), cholesterol (COL) (> 0.4), and alanine aminotransferase (ALT) (> 0.5) correctly detected 80%, 78%, 72%, 70% and 70% of the exudates, respectively. Conclusion We proposed the utilization of a new cutoff of cellular counting, major of 300/mm3, since it would allow improving the detection of exudate ascites, without including the transudate ascites. AST AF/serum ratio (AF/S) showed the major usefulness in the differentiation and characterization of AF; LDH, proteins, cholesterol and ALT might be also acceptable in the above mentioned differentiation. The serum-ascites albumin gradient (SAAG) turned out to be a good marker of portal hypertension associated with cirrhotic processes. Creatine kinase (CK), alkaline phosphatase (ALP), amylase (AMI), total bilirubin (TB), triglycerides (TG) and glucose (GLU) did not allow differentiating exudates from transudates. PMID:27785319

    The early phase of the ConA-induced inflammatory ascites was studied, with special reference to histamine. Concanavalin A (ConA), a cell-surface binding lectin was injected i.p. (25 mg/kg bw) to mice. After 1 h the animals were killed, the ascitic fluid collected and measured. Other agents were injected s.c., 10 min before the ConA-challenge. Exogenous histamine markedly inhibited the ConA-induced ascites. Release of endogenous vasoactive agents from the mast cells by Compound 48/80 had a similar, but slight effect. Cromolyn, a mast cell stabilizing agent, and chloropyramine, a histamine H1 receptor antagonist was ineffective. Although histamine increases endothelial permeability, it did not enhance the formation of ascitic fluid, on the contrary, it inhibited the ConA-induced ascites, presumably due to its known hypotonic effect. It is concluded that ConA-induced ascites is not mediated by mast cell histamine.

    Refractory metal nitrides are synthesized during a self-propagating combustion process utilizing a solid source of nitrogren. For this purpose, a metal azide is employed, preferably NaN.sub.3. The azide is combusted with Mg or Ca, and a metal oxide is selected from Groups III-A, IV-A, III-B, IV-B, or a rare earth metal oxide. The mixture of azide, Ca or Mg and metal oxide is heated to the mixture's ignition temperature. At that temperature the mixture is ignited and undergoes self-sustaining combustion until the starter materials are exhausted, producing the metal nitride.

    Background Arterial blood pressure (BP) is a reliable marker of circulatory dysfunction in cirrhotic patients. There are no prospective studies evaluating the association between different levels of arterial BP and ascites development in compensated cirrhotic patients. Therefore, we evaluated the relationship between arterial BP and ascites development in compensated cirrhotic patients. Materials and Methods A total of 402 patients with compensated HCV-related cirrhosis were prospectively followed during 6 years to identify ascites development. At baseline, patients underwent systolic, diastolic and mean arterial pressure (MAP) measurements. Any history of arterial hypertension was also recorded. The occurrence of events such as bleeding, hepatocellular carcinoma, death and liver transplantation prior to ascites development were considered as competing risk events. Results Over a median of 156 weeks, ascites occurred in 54 patients (13%). At baseline, MAP was significantly lower in patients with ascites development (75.9 mm/Hg [95%CI, 70.3–84.3]) than those without ascites (93.6 mm/Hg [95% CI: 86.6–102.3]). After adjusting for covariates, the 6-year cumulative incidence of ascites was 40% (95%CI, 34%–48%) for patients with MAP<83.32 mm/Hg. In contrast, cumulative incidences of ascites were almost similar among patients with MAP values between 83.32 mm/Hg and 93.32 mm/Hg (7% [95% CI: 4%–12%]), between 93.32 mm/Hg and 100.31 mm/Hg (5% [95% CI: 4%–11%]) or higher than 100.31 mm/Hg (3% [95% CI: 1%–6%]). The MAP was an independent predictor of ascites development. Conclusions The MAP is closely related to the development of ascites in compensated HCV-related cirrhosis. The risk of ascites development increases in 4.4 fold for subjects with MAP values <83.32 mm/Hg. PMID:24755710

    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. PMID:25271300

    Ascites syndrome is a metabolic disorder found in modern broilers that have insufficient pulmonary vascular capacity. Commercial breeding programs have heavily focused on high growth rate, which led to fast-growing chickens, but as a negative consequence, the incidence of ascites syndrome increased. However, not all birds with a high growth rate will suffer from ascites syndrome, which might indicate a genetic susceptibility to ascites. Information on blood gas parameters measured early in life and their relation to ascites susceptibility is expected to contribute to identification on the cause of ascites syndrome. In this study, several physiological parameters, such as blood gas parameters [pH, partial pressure of CO(2) in venous blood (pvCO(2)), and partial pressure of O(2) in venous blood], hematocrit, electrolytes (Na(+), Ca(2+), and K(+)), metabolites (lactate and glucose), were measured at d 11 to 12 of age from 100 female and 100 male broilers. From d 14 onward, the birds were challenged to provoke the development of ascites syndrome. Our results showed that high pvCO(2) values together with low pH values (males) or high pH values (females) in the venous blood of juvenile broilers coincided with ascites. Therefore, blood pvCO(2) and pH in both juvenile male and female broilers seem to be critical factors in ascites pathophysiology and can be used as phenotypic traits to predict ascites susceptibility in juvenile broilers at d 11 to 12. A prediction model was built on a subpopulation of the broilers without any loss in sensitivity (0.52) and specificity (0.78) when applied to the validation population. The parameter sex was included in the prediction model because levels of pvCO(2) and pH that associated with ascites susceptibility are different between males and females. Commercial breeders can include these phenotypic traits in their genetic selection programs to reduce the incidence of ascites syndrome.

    Ascites syndrome is still a problem for chicken industry in various parts of the world. Despite the intensive investigations of this syndrome for many years, its pathogenesis remains unclear. The objective of this study was to analyze the difference in hepatic proteomics between ascites and healthy broilers by two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS). Changes of biochemical parameters of liver and blood were also determined. The results indicated that red blood cell counts (RBC), hematocrit (HCT) and haemoglobin (HGB) of ascites broilers were significantly greater than healthy broilers. Hepatic malondialdehyde (MDA) level of ascites broilers was significantly increased, and the activity of total superoxide dismutase (T-SOD) was significantly decreased. Hepatic lactic acid (LD) level of ascitic broilers were significantly lower than healthy ones. Serum glucose and cholesterol level of ascites broilers were significantly increased, and serum globulin level was significantly decreased in ascites broilers. There was no significant difference in triglyceride (TG) and blood urea nitrogen (BUN) level. The activity of liver hexokinase (HK) and succinodehydrogenase (SDH) in ascites broilers was significantly decreased, and there was no significant difference in the activity of liver pyruvate kinase (PK) and Na+-K+-ATPase. The hepatic proteomics analysis showed that 18 proteins expression difference were identified between ascites and healthy broilers. These proteins were mainly involved in: 1) cytoskeleton; 2) glucose, lipids and amino acid metabolism; 3) cell secretion; 4) cell apoptosis; 5) signal transduction; 6) immune and inflammatory response; and 7) cellular redox homeostasis.

    2012-01-01

    Resistance and tolerance are two complementary mechanisms to reduce the detrimental effects of parasites, pathogens, and production diseases on host performance. Using body weight and ascites data on domesticated chicken Gallus gallus domesticus, we demonstrate the use of random regression animal model and covariance functions to estimate genetic parameters for ascites resistance and tolerance and illustrate the way individual variation in resistance and tolerance induce both genotype re-ranking and changes in variation of host performance along increasing ascites severity. Tolerance to ascites displayed significant genetic variance, with the estimated breeding values of tolerance slope ranging from strongly negative (very sensitive genotype) to weakly negative (less sensitive). Resistance to ascites had heritability of 0.34. Both traits are hence expected to respond to selection. The two complementary defense strategies, tolerance and resistance, were genetically independent. Ascites induced changes to the correlations between ascites resistance and body weight, with the genetic correlations being weak when birds were ascites-free but moderately negative when both healthy and affected birds were present. This likely results because ascites reduces growth, and thus high ascites incidence is genetically related to low adult body weight. Although ascites induced elevated phenotypic and genetic variances in body weight of affected birds, heritability displayed negligible changes across healthy and affected birds. Ascites induced moderate genotype re-ranking in body weight, with the genetic correlation of healthy birds with mildly affected birds being unity but with severely affected birds 0.45. This study demonstrates a novel approach for exploring genetics of defense traits and their impact on genotype-by-environment interactions. PMID:22670223

    This study reports novel insight into the aetiology of pulmonary hypertension and ascites in broiler chickens. The scope of measurements was focused on anatomical and functional parameters, and blood flow patterns in leghorns (resistant to ascites), fast-growing broilers (susceptible to ascites), broilers developing ascites, and ascitic broilers evaluated in vivo using echocardiography, and further examined in the context of postmortem findings. Both, in vivo observed features and postmortem findings, showed clear differences between broilers and leghorns, and between normal and ascitic broilers. Abnormalities in the heart chamber geometry and blood flow patterns were detected upon echocardiographic examination in all ascitic broilers. Right and left atrio-ventricular (AV) valve regurgitation were common findings in ascitic broilers and some apparently normal broilers, with left AV valve insufficiency being a predominant feature with respect to degree and frequency of occurrence. Blood flow disturbances were not detected in leghorns. Left ventricular fractional shortening (functional parameter) was considerably reduced (P < 0.01) in ascitic birds (mean: 21.7 +/- 2.0 SE) in comparison with normal broilers (mean: 39.1 +/- 3.6 SE), or leghorns (mean: 43.3 +/- 2.4 SE). The presented findings indicate that pathological and functional changes in the left ventricle and atrium play a significant role in the pathogenesis of ascites in broilers. Severe dilation of the left atrium and pulmonary veins seen on postmortem examination, as well as regurgitant blood flow in the left atrium, demonstrated by Doppler study in ascitic birds, provide evidence that chronically elevated pressure in the left atrium is involved in the aetiology of pulmonary hypertension and ascites in fast-growing broilers.

    Anemia is a common complication in malarial infection. Direct destruction and ineffective erythropoesis does not adequately explain the cause of anemia in malaria. We present a case with refractory megaloblastic anemia with asymptomatic falciparum malaria. We hypothesize that promoter variants in the inducible nitric oxide synthase gene might be the cause of severe refractory megaloblastic anemia and pancytopenia in our patient. Malaria should always be kept in mind as a cause of anemia especially in endemic areas even if the child is asymptomatic or there is no demonstrable parasite on routine smear examination.

    Acute kidney injury in the setting of ascites and cirrhosis is a medical emergency characterized by significant morbidity and mortality. Clinicians other than gastroenterologists are often the front line against acute kidney injury for patients with ascites. Owing to the specifics of cirrhotic physiology, the treatment and prevention of acute kidney injury in the setting of ascites has unique features, widespread knowledge of which will benefit our patients with cirrhosis. Early detection and treatment of infection, maximization of cardiac output, and avoidance of medications that limit cardiorenal adaptations to arterial underfilling are part of a multipronged strategy to protect the renal function of our patients with cirrhosis and ascites.

    To determine the ultrasonographic findings that predict death in fetal ascites. This was a retrospective cohort study involving pregnancies with ultrasonographic findings related to fetal ascites. The inclusion criteria were as follows: single pregnancy with a live fetus; ultrasound findings of ascites; ascites unrelated to maternal fetal alloimmunization; and pregnancy follow-up at our institution. The χ2-test was used to evaluate the association of ultrasound findings and death. Multiple logistic regression analysis was performed to determine the ultrasound findings that are predictive of death prior to hospital discharge. A total of 154 pregnancies were included in the study. In 8 (5.19%) cases, ascites was an isolated finding, and in 146 cases, other alterations were observed during the ultrasound evaluation. Death before hospital discharge occurred in 117 cases (76.00%). The following ultrasonographic findings were significantly associated with death: gestational age at diagnosis <24 weeks (P<0.0001); stable/progressive ascites evolution (P=0.004); the presence of hydrops (P<0.0001); and the presence of cystic hygroma (P<0.0001). The presence of hydrops, the presence of respiratory tract malformations, and stable/progressive ascites evolution were significantly associated with the prediction of death. Based on ultrasound examination, the presence of hydrops, malformation of the respiratory tract, and stable/progressive evolution of ascites increase the chances of death in cases of fetal ascites.

    Malignant ascites is debilitating for patients with advanced cancer. As shown previously, tumour cell production of vascular endothelial growth factor might be a major cause of the formation of malignant ascites. Intraperitoneal bevacizumab could therefore be an option for symptom control in refractory ascites. Patients with advanced gastrointestinal cancer and malignant ascites who had undergone paracentesis at least twice within the past 4 weeks were randomly assigned in a 2:1 ratio to intraperitoneal bevacizumab (400 mg absolute) or placebo after paracentesis. During the 8-week treatment period, a minimum interval of 14 d was kept between the applications of the study drug. Primary end-point was paracentesis-free survival (ParFS). Fifty-three patients (median age 63 years) were randomised. Forty-nine patients received at least one study drug application and qualified for the main analysis. The proportion of patients with at least one common toxicity criteria grade III-V event was similar with 20/33 (61%) on bevacizumab and 11/16 (69%) on placebo. Median ParFS was 14 d (95% confidence interval [CI]: 11-17) in the bevacizumab arm and 10.5 d (95% CI: 7-21) on placebo (hazard ratio 0.74, 95% CI: 0.40-1.37; P = 0.16). The longest paracentesis-free period was 19 d on bevacizumab (range 6-66 d) and 17.5 d in the placebo arm (range 4-42) (P = 0.85). Median overall survival was 64 d (95% CI: 45-103) on bevacizumab compared to 31.5 d (95% CI: 20-117) on placebo (P = 0.31). Intraperitoneal bevacizumab was well tolerated. Overall, treatment did not result in a significantly better symptom control of malignant ascites. However, patients defined by specific immune characteristics may benefit.

    The aim of this study was to evaluate the efficacy and safety of cell-free concentrated ascites reinfusion therapy (CART) on a large amount of ascites. Fifty-eight CART procedures were performed in nine patients with ovarian, endometrial, or cervical cancer from February 2013 to September 2014. The medical records were retrospectively reviewed for the amount of collected ascites, vital signs, and laboratory results before and after CART. No obvious change in the plasma protein and plasma albumin concentration was found after CART for < 5 L of ascites; however, obvious increases in both were observed in CART for ≥ 5 L of ascites (P < 0.001). The optimum cut-off value for obtaining a positive variant of plasma protein and plasma albumin after CART was 7.9 L. CART for ≥ 5 L of ascites did not increase the risk of transient water retention in the body (odds ratio = 2.2; 95% confidence interval: 0.35-13.83; P = 0.38); however, CART for ≥ 7.9 L of ascites increased the risk of water retention (odds ratio = 8.4; 95% confidence interval: 1.91-44.09; P = 0.004). The optimal cut-off value of ascites for predicting water retention due to CART was 9.2 L. Massive ascites collection in CART < 9.2 L appears to be a safe and effective treatment for improving general condition, plasma protein, and electrolytes in gynecologic cancer patients. © 2015 Japan Society of Obstetrics and Gynecology.

Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, from November 2007 to November 2014. All patients on maintenance hemodialysis and age > 16 years with ascites were included. Frequencies and percentages were computed for different categorical variables. Chi-square or Fischer exact test were used to identify factors associated with ascites like frequency of hemodialysis, serum albumin and cardiac ejection fraction (EF). Odds ratios were calculated for associated factors. Ninety patients were included in this study; 55.5% were males. Median age was 33 years. Cause of ascites was nephrogenic in 77.8%, cardiac failure in 16.7%, hypothyroidism in 6.67%, liver cirrhosis in 4.4%, abdominal tuberculosis in 2.2%, and peritoneal carcinomatosis in 1.1% patients. The ascites was severe in 53.3% patients and severity was associated with serum albumin < 2.8 gm/dL(p=0.007) and cardiac EF < 40% (p=0.028). The ascites was low serum ascites albumin gradient (SAAG), high protein type (LSHP) in 60% patients and associated with hemorrhage (p=0.040). High SAAG, high protein (HSHP) ascites, found in 33.3%, was associated with cardiac EF < 40% (p=0.005) and portal hypertension (p=0.048). High SAAG, low protein (HSLP) ascites, seen in 6.7%, was associated with portal hypertension (p=0.006). The commonest cause of ascites in hemodialysis dependent patients is nephrogenic followed by cardiac failure. Low serum albumin and low cardiac EF predispose to severe forms of ascites.

    (1) Pulmonary hypertension syndrome followed by ascites is a metabolic disorder in broilers that occurs more often in fast-growing birds and at cool temperatures. (2) Knowledge of the genetic relationships among ascites-related traits and performance traits like carcase traits or feed efficiency traits is required to design breeding programmes that aim to improve the degree of resistance to ascites syndrome as well as production traits. The objective of this study was to estimate these genetic correlations. (3) Three different experiments were set up to measure ascites-related traits (4202 birds), feed efficiency traits (2166 birds) and carcase traits (2036 birds). The birds in different experiments originated from the same group of parents, which enabled the estimation of genetic correlations among different traits. (4) The genetic correlation of body weight (BW) measured under normal conditions and in the carcase experiment with the ascites indicator trait of right ventricle to total ventricle ratio (RV:TV) measured under cold conditions was 0.30. The estimated genetic correlation indicated that single-trait selecting for BW leads to an increase in occurrence of the ascites syndrome but that there are realistic opportunities of multi-trait selection of birds for improved BW and resistance to ascites. (5) Weak but positive genetic relationships were found between feed efficiency and ascites-related traits suggesting that more efficient birds tend to be slightly more susceptible to ascites. (6) The relatively low genetic correlation between BW measured in the carcase or in the feed efficiency experiments and BW measured in the ascites experiment (0.49) showed considerable genotype by environment interaction. (7) These results indicate that birds with high genetic potential for growth rate under normal temperature conditions have lower growth rate under cold-stress conditions due to ascites.

    Barbiturate anesthesia, which is commonly used for refractory status epilepticus, is an effective treatment, but with many significant complications. The relationship between the duration of this extreme therapy and the ultimate outcome of refractory status epilepticus has not been well studied. We report a 7-year-old girl who presented with refractory status epilepticus secondary to presumed encephalitis with a focal lesion on cranial magnetic resonance imaging. She was treated for 70 days with high-dose antiepileptic drugs and recovered with a residual seizure disorder. This case suggests that, if the status epilepticus is due to a reversible cause such as encephalitis, neurologic recovery may occur despite this very prolonged course of extreme therapy.

    Acute graft-versus-host disease (GVHD) is a major complication of allogeneic stem cell transplantation (SCT) and can be readily controlled by systemic high-dose steroids in many patients. However, patients whose GVHD is refractory to this therapy have a poor prognosis. Refractory patients have ongoing end-organ damage despite effective immunosuppression with second-line regimens, suggesting pathomechanisms independent from the initiating T-cell attack. To explore whether endothelial damage might contribute to GVHD refractoriness and to study the role of angiopoietin-2 (ANG2) in this process, we have compared kinetics of T-cell activation markers and markers of endothelial dysfunction in the serum of patients with sensitive (n = 23) and refractory GVHD (n = 25). Longitudinal measurements of soluble FAS ligand along with other immune markers demonstrate that refractory patients are not exposed to an overwhelming or unresponsive T-cell attack. However, in contrast to sensitive GVHD, refractory GVHD was associated with rising thrombomodulin levels and high ANG2/ vascular endothelial-derived growth factor ratios. Patients with refractory GVHD showed significantly increased ANG2 levels already before SCT. These results suggest that endothelial cell vulnerability and dysfunction, rather than refractory T-cell activity, drives treatment refractoriness of GVHD and opens new avenues for prediction and control of this devastating condition.

    Refractory status epilepticus (RSE) has a high morbidity and mortality. There are currently no definitive data to guide both the optimal choice of therapy and treatment goals. This review focuses on RSE diagnosis and outcome and discusses both commonly used and anecdotal therapies for RSE. The challenges in performing randomized controlled trials (RCTs) in neurocritical care and more specifically for the treatment of RSE are illustrated by the early termination of the first RCT of RSE due to low recruitment that compared propofol to barbiturates. Recent case series include the successful treatment of recurrent RSE with ketamine, intravenous lacosamide as an add-on treatment, the use of combination antiepileptics (phenytoin, levetiracetam, and pregabalin), and surgical treatments (vagal nerve and deep brain stimulation) for the control of RSE. A number of different therapeutic options are available for the treatment of RSE but none have been shown to be superior to others at this point.

    Intravenous ciclosporin 4 mg/kg daily is rapidly effective as a salvage therapy for patients with refractory colitis, who would otherwise face colectomy, but its use is controversial because of risk of toxicity, and long-term failure rate. Opportunistic infections remain a serious concern, with a number of reports of death related to ciclosporin. Renal and neurotoxicity are also well-recognized. The drug should not be continued for more than 3-6 months and its main role is as a bridge to azathioprine or 6-mercaptopurine. Risks of toxicity can be reduced by using lower doses (2 mg/kg/day intravenously), by oral microemulsion ciclosporin, or by monotherapy without corticosteroids. Preliminary evidence shows good response rates, but further studies are needed to confirm optimal use of this potent, but hazardous, therapy.

    Severe ulcerative colitis is defined by more than six bloody stools daily and evidence of toxicity, demonstrated by fever, tachycardia, anemia, or an elevated erythrocyte sedimentation rate. Fulminant disease represents a subset of severe disease with signs and symptoms suggestive of increased toxicity. Treatment of severe colitis includes intravenous corticosteroid administration, with consideration of intravenous infliximab 5 mg/kg. Failure to show improvement after 3 to 5 days is an indication for colectomy or treatment with intravenous cyclosporine. We report a 23-year-old Hispanic woman with decompensated cirrhosis presenting with new-onset fulminant ulcerative colitis and resulting polymicrobial bacteremia, requiring colectomy for infection source control and colitis treatment.

    Ascites is more difficult to detect when only a small quantity is present. The aim of this pilot study was to determine the optimal bowel sound characteristics in order to distinguish no ascites from small-volume ascites by advanced processing of bowel sound wave patterns. This analysis results in the definition of the normal range of bowel sound patterns, thus providing a novel, simple, and noninvasive way of determining on abnormal pattern, which may reflect presence of small volume ascites. Cirrhotic patients with radiologically proven small-volume ascites and a control group were subjected to bowel sound recordings. The latter were analyzed using a denoising wavelet transform-based filter and a higher-order crossings-based technique in a blinded fashion for linearly distinguishing the two classes. Scatter plots of third-order zero crossings reflect distinct changes seen in the denoised bowel sound pattern between patients and controls due to altered transmission path, providing a distinct separation of all cirrhotic patients with small ascites from controls (P < 0.0001). We conclude that the proposed bowel sounds analysis appears to provide new information regarding the changes of the bowel sound patterns due to the presence of small-volume ascites, potentially contributing towards a safe, effective, noninvasive, and easily implemented alternative method for the diagnosis of small volume ascites at the bedside.

    The aim of this study was to investigate the clinical factors for predicting overall survival (OS) and the significance of a minute amount of ascites on computed tomography (CT) in patients with locally advanced pancreatic cancer (LAPC) treated with chemoradiotherapy (CRT). Between 2003 and 2011, 48 consecutive patients with LAPC were treated with CRT. Various clinical factors, including ascites, were evaluated for correlation with OS. A subset analysis of 16 patients with a minute amount of ascites was also performed. The median survival duration and the 1-year OS rates were 11.5 months and 50%, respectively. A minute amount of ascites on CT and elevated carbohydrate antigen 19-9 (CA19-9) level were significantly associated with poorer OS. In 16 patients with ascites, the amount of ascites increased in the course of the disease, and these were considered to be cancerous clinically, regardless of the amount. A minute amount of ascites and CA19-9 were important prognostic factors in CRT. Any amount of ascites was considered an early indicator of peritoneal carcinomatosis in LAPC.

CCA is a rare condition, and there is limited understanding of its pathophysiology and treatment options. We also review the patient’s treatment course mitigated with octreotide and total parenteral nutritional support, as there are no current established guidelines for CCA. Early recognition of possible association with Ehlers-Danlos syndrome is important for quick intervention and successful management of pediatric patients. PMID:28119937

    A study of the mechanism of hexokinase II from ascites cells the effects of its binding to mitochondrial membranes has been carried out by computer simulation. This is based on experimental data of Kosow and Rose and of Gumaa and McLean, and the theoretical methods of cleveland. For the soluble enzyme the mechanism is random with ternary produce-inhibition complexes; when bound to mitochondria, the mechanism becomes ordered-on, random-off, as the binding of ATP to the free enzymes becomes negligibly slow. The requirements of experimental data for mechanistic studies are discussed.

    An investigation of the efficacy of astatine-211-tellurium colloid for the treatment of experimental malignant ascites in mice reveals that this ..cap alpha..-emitting radiocolloid can be curative without causing undue toxicity to normal tissue. By comparison, negatron-emitting phosphorus-32 as colloidal chromic phosphate had no antineoplastic activity. The most compelling explanation for this striking difference is the dense ionization and short range of action associated with ..cap alpha..-emission. These results have important implications for the development and use of ..cap alpha..-emitters as radiocolloid therapy for the treatment of human tumors.

    Pulmonary arterial hypertension (PAH) syndrome in broilers (also known as ascites syndrome and pulmonary hypertension syndrome) can be attributed to imbalances between cardiac output and the anatomical capacity of the pulmonary vasculature to accommodate ever-increasing rates of blood flow, as well as to an inappropriately elevated tone (degree of constriction) maintained by the pulmonary arterioles. Comparisons of PAH-susceptible and PAH-resistant broilers do not consistently reveal differences in cardiac output, but PAH-susceptible broilers consistently have higher pulmonary arterial pressures and pulmonary vascular resistances compared with PAH-resistant broilers. Efforts clarify the causes of excessive pulmonary vascular resistance have focused on evaluating the roles of chemical mediators of vasoconstriction and vasodilation, as well as on pathological (structural) changes occurring within the pulmonary arterioles (e.g., vascular remodeling and pathology) during the pathogenesis of PAH. The objectives of this review are to (1) summarize the pathophysiological progression initiated by the onset of pulmonary hypertension and culminating in terminal ascites; (2) review recent information regarding the factors contributing to excessively elevated resistance to blood flow through the lungs; (3) assess the role of the immune system during the pathogenesis of PAH; and (4) present new insights into the genetic basis of PAH. The cumulative evidence attributes the elevated pulmonary vascular resistance in PAH-susceptible broilers to an anatomically inadequate pulmonary vascular capacity, to excessive vascular tone reflecting the dominance of pulmonary vasoconstrictors over vasodilators, and to vascular pathology elicited by excessive hemodynamic stress. Emerging evidence also demonstrates that the pathogenesis of PAH includes characteristics of an inflammatory/autoimmune disease involving multifactorial genetic, environmental, and immune system components.

    Some cytochemical and immunocytochemical investigations were carried out on actively growing Yoshida ascites sarcoma cells. These cells displayed an intense granular alpha-naphthylacetate esterase (ANAE) staining while the alpha-naphthylbutyrate esterase (ANBE) reaction was in part fluoride-sensitive and marked particularly in the large-size malignant cells. Acid phosphatase as well as peroxidase activities were not detected. The lack of immunoreactive lysozyme and alpha 1-antitrypsin suggested a poor differentiation of the above-mentioned tumor cells, but fibronectin and S-100 protein where highly expressed, as in tumors arising from the mononuclear phagocyte system.

    Malignant ascites constitute a unique tumor microenvironment providing a physical structure for the accumulation of cellular and acellular components. Ascites is initiated and maintained by physical and biological factors resulting from underlying disease and forms an ecosystem that contributes to disease progression. It has been demonstrated that the cellular contents and the molecular signatures of ascites change continuously during the course of a disease. Over the past decade, increasing attention has been given to the characterization of components of ascites and their role in the progression of ovarian cancer, the most malignant gynecologic cancer in women. This review will discuss the role of ascites in disease progression, in terms of modulating cancer cell behavior and contributing to tumor heterogeneity. © 2016 The Authors.

    Borderline ovarian tumors are benign but relatively large tumors that are often initially mistaken as ovarian cancers. We report three cases of stage I borderline ovarian tumors having massive ascites that we (preoperatively) suspected of being advanced ovarian cancer. The three patients (35, 47, and 73 years old) reported feeling fullness of the abdomen before consulting their gynecologist. By CT scan, they were diagnosed with a pelvic tumor accompanied by massive ascites, the diameters of which were 11, 20, and 11 cm, respectively. Postsurgical pathology showed all were stage I borderline ovarian tumors without dissemination; two were mucinous and one was serous. The amount of ascites was 6,300, 2,600, and 3,600 mL, respectively, and was serous in all. Cytodiagnosis of the ascites found that one was positive for tumor cells and two were negative. After resection of the mass, the ascites disappeared in all three cases. No pleural effusion was present at any time. The literature is reviewed concerning ascites and pleural effusions linked to ovarian tumors, and a supposition is forwarded of why pleural effusion presents sporadically in these cases.

    Chemotherapy resistance is the major reason for the failure of ovarian cancer treatment. One mechanism behind chemo-resistance involves the upregulation of multidrug resistance (MDR) genes (ABC transporters) that effectively transport (efflux) drugs out of the tumor cells. As a common symptom in stage III/IV ovarian cancer patients, ascites is associated with cancer progression. However, whether ascites drives multidrug resistance in ovarian cancer cells awaits elucidation. Here, we demonstrate that when cultured with ascites derived from ovarian cancer-bearing mice, a murine ovarian cancer cell line became less sensitive to paclitaxel, a first line chemotherapeutic agent for ovarian cancer patients. Moreover, incubation of murine ovarian cancer cells in vitro with ascites drives efflux function in these cells. Functional studies show ascites-driven efflux is suppressible by specific inhibitors of either of two ABC transporters [Multidrug Related Protein (MRP1); Breast Cancer Related Protein (BCRP)]. To demonstrate relevance of our findings to ovarian cancer patients, we studied relative efflux in human ovarian cancer cells obtained from either patient ascites or from primary tumor. Immortalized cell lines developed from human ascites show increased susceptibility to efflux inhibitors (MRP1, BCRP) compared to a cell line derived from a primary ovarian cancer, suggesting an association between ascites and efflux function in human ovarian cancer. Efflux in ascites-derived human ovarian cancer cells is associated with increased expression of ABC transporters compared to that in primary tumor-derived human ovarian cancer cells. Collectively, our findings identify a novel activity for ascites in promoting ovarian cancer multidrug resistance. PMID:26148191

    Ovarian cancer (OC) is the eighth most lethal gynecological malignancy and the main cause of gynecological cancer death in industrialized countries. Malignant ascites is often found in OC, with about 10% of patients suffering from recurrent OC. Tumor cells in OC-associated malignant ascites promote disease recurrence and patient mortality is mainly associated with widespread metastasis to serosal surfaces and accompanying peritoneal effusions. Targeted therapies have recently been developed as novel therapeutic options for malignant ascites. The tri-functional anti-epithelial cell adhesion molecule and anti-cluster of differentiation 3 monoclonal antibody catumaxumab has been assessed in the therapy of malignant ascites, and proven to significantly reduce the ascitic flow rate when applied into the peritoneal cavity. The anti-angiogenic targeted agent bevacizumab has also shown good effects in the symptomatic treatment of malignant ascites, significantly prolonging the time until the next paracentesis. Vascular endothelial growth factor (VEGF) Trap, or aflibercept, is a fusion protein that inhibits VEGF-receptor binding. Aflibercept has proven to be effective in reduction of ascites, diminishing clinical symptoms of ascites and prolonging the time to next paracentesis. All three agents we review in the present article are effective in symptomatic control of ascites, leading to a rapid reduction of effusion and prolonging the time interval between paracenteses. However, no improvement in overall survival was observed in any of the clinical trials reported. We, thus, conclude that further investigations on larger patient series are needed to clarify whether the reduction of ascites by these targeted agents leads to a prolongation in tumor-related survival or not.

    Ascites is a multi-faceted disease commonly observed in fast growing broilers, which is initiated when the body is insufficiently oxygenated. A series of events follow, including an increase in pulmonary artery pressure, right ventricle hypertrophy, and accumulation of fluid in the abdominal cavity and pericardium. Advances in management practices along with improved selection programs have decreased ascites incidence in modern broilers. However, ascites syndrome remains an economically important disease throughout the world, causing estimated losses of $100 million per year. In this study, a 60 K Illumina SNP BeadChip was used to perform a series of genome wide association studies (GWAS) on the 16th and 18th generation of our relaxed (REL) line descended from a commercial elite broiler line beginning in 1995. Regions significantly associated with ascites incidence were identified on chromosome 2 around 70 megabase pairs (Mbp) and on chromosome Z around 60 Mbp. Five candidate single nucleotide polymorphisms (SNP) were evaluated as indicators for these 2 regions in order to identify association with ascites and right ventricle to total ventricle weight (RVTV) ratios. Chromosome 2 SNP showed an association with RVTV ratios in males phenotyped as ascites resistant and ascites susceptible (P = 0.02 and P = 0.03, respectively). The chromosome Z region also indicates an association with resistant female RVTV values (P = 0.02). Regions of significance identified on chromosomes 2 and Z described in this study will be used as proposed candidate regions for further investigation into the genetics of ascites. This information will lead to a better understanding of the underlying genetics and gene networks contributing to ascites, and thus advances in ascites reduction through commercial breeding schemes.

  9. Intrathecal ziconotide for refractory pain.

    PubMed

    Doggrell, Sheila A

    2004-07-01

    For cancer and AIDS patients, 10-30% of pain is refractory to strong opioids, requiring intraspinal administration for pain management. Ziconotide is a selective N-type calcium channel blocker, which inhibits neurotransmitter release, and following intrathecal administration will affect primary nociceptive afferents. In 108 patients with previously unmanaged refractory pain despite the use of systemic or intrathecal opioids, in the initial titration phase, the mean Visual Analogue Scale of Pain Intensity scores improved more in the ziconotide group (53%) than the placebo group (18%). Serious adverse effects were more common in the ziconotide group (31%) than placebo group (10%) in the initial titration phase. In the 48 patients receiving ziconotide, who proceeded to the maintenance phase, the benefit of ziconotide was continued. Until a new approach with a better effectiveness/adverse effects profile than ziconotide for refractory pain emerges, further optimisation of ziconotide for use in the treatment of refractory pain should be undertaken.

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

    Background Renal cysts are common in old patients, and usually remain untreated. Giant renal cyst measuring more than 15 cm in diameter and containing more than 1500 mls of serous fluid are rarely seen. We report a case of a 75-year-old man with a giant right renal cyst. Case presentation A 75-year-old man presented with a five years history of suprapubic pain, abdominal distension. He had no urological symptoms. Physical examination revealed a distended abdomen with shifting dullness. Routine hematology, biochemistry, and serum tumor markers were within normal limits. Erroneously diagnosed as ascites on ultrasonographic examination. Abdominal paracentesis of supposed ascites was performed. The diagnosis of giant renal cyst was finally made by Computed tomography (CT) and patient underwent continuous percutaneous catheter drainage with negative pressure, whereby 8 liters of fluid were removed with negative cytology. Subsequent Computed tomography after 6 months revealed disparition of the cysts, and the patient remained asymptomatic. Conclusion Giant renal cysts are uncommon; we conclude that the CT remains the best exam in patients evaluated for giant renal cyst. This to the best of our knowledge is the largest renal cyst in the medical literature. Studies are needed with particular attention to the factors associated with renal cyst enlargement.

    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.

    A flying spot ultraviolet microscope, employing a fast scan and pulsed operation of the raster, has been used to induce radiation damage in ascites tumor slide cultures, and to study by time-lapse cinematography the progressive stages of cell damage. The cells observed came from a strain (EF7) of the Ehrlich ascites carcinoma. Irradiated cells were found to show a characteristic syndrome of damage, involving blebbing at the cell surface, while control cells in the adjacent areas of the preparation remained unchanged. The end of the blebbing period is marked by swelling of the cells, and the time taken for this phenomenon to occur was used as a measure of the severity of the damage. It was found that the time required for swelling is dependent on the size of the dose employed, as well as on the sensitivity of the cells. This latter sensitivity was found to decline as the physiological age of the tumor increased. If ultraviolet illumination below 255 mµ is excluded, no symptoms of damage occur, even when very large doses are used. These observations are discussed in relation to the nature of the system in the cell which is affected. PMID:13654439

    Objective Hemorrhagic cystitis is a challenging clinical entity with limited evidence available to guide treatment. The use of intravesical silver nitrate has been reported, though supporting literature is sparse. Here, we sought to assess outcomes of patients treated with intravesical silver nitrate for refractory hemorrhagic cystitis. Material and methods We identified nine patients with refractory hemorrhagic cystitis treated at our institution with intravesical silver nitrate between 2000–2015. All patients had failed previous continuous bladder irrigation with normal saline and clot evacuation. Treatment success was defined as requiring no additional therapy beyond normal saline irrigation after silver nitrate instillation prior to hospital discharge. Results Median patient age was 80 years (IQR 73, 82). Radiation was the most common etiology for hemorrhagic cystitis 89% (8/9). Two patients underwent high dose (0.1%–0.4%) silver nitrate under anesthesia, while the remaining seven were treated with doses from 0.01% to 0.1% via continuous bladder irrigation for a median of 3 days (range 2–4). All nine patients (100%) had persistent hematuria despite intravesical silver nitrate therapy, requiring additional interventions and red blood cell transfusion during the hospitalization. There were no identified complications related to intravesical silver nitrate instillation. Conclusion Although well tolerated, we found that intravesical silver nitrate was ineffective for bleeding control, suggesting a limited role for this agent in the management of patients with hemorrhagic cystitis.

    Constipation is a common complication in critically ill children and it is occasionally resistant to the drugs typically used in treatment. Neostigmine has been used in some cases of refractory constipation in critically ill adults. There is no reference to its use in critically ill children. We describe 3 cases of refractory constipation in critically ill children treated with intravenous neostigmine by continuous infusion. Two patients responded well. There were no adverse effects. We conclude that continuous intravenous neostigmine can be effective in critically ill children with refractory constipation. Further studies are necessary to determine the dose and safety of the treatment.

    The American Academy of Periodontology has developed the following parameter on the treatment of "refractory " periodontitis. Patients should be informed of the disease process, therapeutic alternatives, potential complications, expected results, and their responsibility in treatment. Consequences of no treatment should be explained. No treatment is very likely to result in further progression of the disease and eventual tooth loss. Given this information, patients should then be able to make informed decisions regarding their periodontal therapy.

    In order to achieve the required low reactor mass per unit electrical power for space reactors, refractory alloys are essential due to their high operating temperature capability that in turn enables high thermal conversion efficiencies. One of the key issues associated with refractory alloys is their performance in a neutron irradiation environment. The available radiation effects data are reviewed for alloys based on Mo, W, Re, Nb and Ta. The largest database is associated with Mo alloys, whereas Re, W and Ta alloys have the least available information. Particular attention is focused on Nb-1Zr, which is a proposed cladding and structural material for the reactor in the Jupiter Icy Moons Orbiter (JIMO) project. All of the refractory alloys exhibit qualitatively similar temperature-dependent behavior. At low temperatures up to ~0.3TM, where TM is the melting temperature, the dominant effect of radiation is to produce pronounced radiation hardening and concomitant loss of ductility. The radiation hardening also causes a dramatic decrease in the fracture toughness of the refractory alloys. These low temperature radiation effects occur at relatively low damage levels of ~0.1 displacement per atom, dpa (~2×1024 n/m2, E>0.1 MeV). As a consequence, operation at low temperatures in the presence of neutron irradiation must be avoided for all refractory alloys. At intermediate temperatures (0.3 to 0.6 TM), void swelling and irradiation creep are the dominant effects of irradiation. The amount of volumetric swelling associated with void formation in refractory alloys is generally within engineering design limits (<5%) even for high neutron exposures (>>10 dpa). Very little experimental data exist on irradiation creep of refractory alloys, but data for other body centered cubic alloys suggest that the irradiation creep will produce negligible deformation for near-term space reactor applications.

    AIM: To measure plasma D-dimer levels in cirrhotic patients with and without ascites, assessing the effect of ascites resolution in D-dimer concentration. METHODS: Seventy consecutive cirrhotic patients (M = 44, F = 26, mean age 65 years, SD ± 13), observed from October 2005 to March 2006 were enrolled. Circulating D-dimer levels were measured using a latex-enhanced, immunoturbidimetric test. In patients with ascites (n = 42) the test was repeated after ascites resolution. RESULTS: Ascites was present in 42 patients (group A) and absent in 28 (group B). Group A patients had more advanced liver disease. Hepatocellular carcinoma (HCC) was diagnosed in 14 patients and was more frequent in group B. Above normal range D-dimers were found in 45/70 patients. High D-dimers were more frequent in group A than in group B (P = 0.001). High D-dimers were associated with presence of HCC (P = 0.048) only in group B. After ascites resolution, obtained in all patients, mean D-dimer values decreased in those 34 patients with high basal levels (P = 0.007), returning to normal in 17. CONCLUSION: In patients with liver cirrhosis, ascites and HCC are the main factors associated with increased fibrinolytic activity. PMID:18330946

    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.

    Ascites secondary to cancer has a dramatic effect on all aspects of patients' lives. Healthcare professional surveys have shown that there is considerable variation in the management of ascites. To explore patients' experiences of living with ascites and its management. Qualitative research study using digitally recorded semi-structured interviews. Twelve adult patients with ascites who, between them, had undergone 47 paracentesis procedures in hospitals and/or specialist palliative care units in Southern England. Symptoms were pain, discomfort and effects on appetite, digestion, breathing and mobility. All participants had experienced paracentesis in hospital or a specialist palliative care unit, and these experiences differed. They had views on what constituted a good procedure: setting, competence and pain control. They reported rapid improvement of symptoms after paracentesis. While some did not like the idea of a semi-permanent drain, those with them appreciated the convenience and not having to wait for repeated admissions or the recurrence of symptoms. The interval between ascitic taps was seen as a useful guide as to when a semi-permanent drain should be offered. Participants had mixed views on participation in a hypothetical randomised controlled trial of repeated ascitic taps versus semi-permanent drains. Patients' experiences of ascites management are variable and could be improved. These experiences can inform healthcare professionals. They have views on when semi-permanent drains should be offered and future research.

    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. PMID:16569225

    Although ascites causes abdominal expansion, its effects on abdominal muscle function are uncertain. In the present study, progressively increasing ascites was induced in supine anesthetized dogs, and the changes in abdominal (DeltaPab) and airway opening (DeltaPao) pressure obtained during stimulation of the internal oblique and transversus abdominis muscles were measured; the changes in internal oblique muscle length were also measured. As ascites increased from 0 to 100 ml/kg body wt, Pab and muscle length during relaxation increased. DeltaPab also showed a threefold increase (P < 0.001). However, DeltaPao decreased (P < 0.001). When ascites increased further to 200 ml/kg, resting muscle length continued to increase and muscle shortening during stimulation became very small so that active muscle length was 155% of the resting muscle length in the control condition. Concomitantly, DeltaPab returned to the control value, and DeltaPao continued to decrease. Similar results were obtained with the animals in the head-up posture, although the decrease in DeltaPao appeared only when ascites was greater than 125 ml/kg. It is concluded that 1) ascites adversely affects the expiratory action of the abdominal muscles on the lung; 2) this effect results primarily from the increase in diaphragm elastance; and 3) when ascites is severe, the abdomen cross-sectional area is also increased and the abdominal muscles are excessively lengthened so that their active pressure-generating ability itself is reduced.

    Three to 20 hr after an i.p. injection of /sup 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 /sup 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 /sup 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 /sup 64/Cu' was preferentially associated with the protein fraction from liver. Further experiments indicated that, in vivo, /sup 64/Cu was bound to the DNA of ascites cells.

    Ascites is an accumulation of serous fluid in the abdominal cavity. It can be caused by both malignant and non-malignant conditions and produces distressing symptoms. There have been no qualitative studies looking at the experiences of patients with non-malignant ascites. To explore the experiences of patients living with non-malignant ascites and its management. Also, to explore the views of these patients about services available to them. Phenomenological qualitative research study using digitally recorded semi-structured interviews. Six adult patients with non-malignant ascites who were receiving paracentesis to manage their symptoms in an acute hospital day unit. Participants experienced a wide variety of physical symptoms. They discussed how the ascites impacted on their social lives. They had views on diuretics, low sodium diet and paracentesis as methods of symptom management. Participants' confidence in staff performing paracentesis was a common finding, particularly as ultrasound was rarely used. While only some were suitable for liver transplant, all discussed their future care needs. Participants' experiences of non-malignant ascites are that it has a considerable effect on their quality of life. Patients like the system of day case admission for drainage, but question whether this is sustainable. Advanced practitioners can successfully provide a paracentesis service for these patients in hospitals and potentially this is transferable to hospices. Patients seemed happy to consider the option of semi-permanent drains and pumps as methods of managing ascites.

    This study examined the putative role of blood vessel pathology in the development of ascites in broilers. Major blood vessels (aorta, brachiocephalic arteries, pulmonary arteries, and vena cava) from normal commercial male broiler chickens, and broilers that developed congestive heart failure (CHF) with or without ascites were subjected to gross and microscopic examination. On cross-section, grossly, the arteries from normal broilers and those showing dilated cardiomyopathy without ascites appeared circular, with firm wall tone characteristic of the normal artery. In contrast, the arteries from ascitic broilers appeared flaccid and lacked elasticity, which was evidenced by collapsing, ellipsoid cross-sectional arterial lumen owing to the structural weakness of the arterial walls. Microscopically, ascitic broilers showed thinning or occasionally total loss of elastic elements in the arterial wall, and reduced network density of the structural matrix of the vascular wall, as well as increased thickness of fibers in vena cava. The structural changes seen in the major arteries from ascitic broilers are maladaptive, and as such would definitively impose an increased hemodynamic burden on the already failing heart pump. The changes in veins are indicative of pathological remodeling conducive to increased permeability of the vascular wall, particularly in the situation when a poorly distensible structure is further subjected to wall stress associated with increased pressure and volume overload. Taken together, increased hemodynamic burden and reduced structural density of the venous wall constitute conditions conducive for seepage and accumulation of ascitic fluid.

    Background: Although steroid injection prevents stricture after esophageal endoscopic submucosal dissection (ESD), some patients require repeated sessions of endoscopic balloon dilation (EBD). We investigated the risk for refractory stricture despite the administration of steroid injections to prevent stricture in patients undergoing esophageal ESD. Refractory stricture was defined as the requirement for more than three sessions of EBD to resolve the stricture. In addition, the safety of steroid injections was assessed based on the rate of complications. Patients and methods: We analyzed data from 127 consecutive patients who underwent esophageal ESD and had mucosal defects with a circumferential extent greater than three-quarters of the esophagus. To prevent stricture, steroid injection was performed. EBD was performed whenever a patient had symptoms of dysphagia. Results: The percentage of patients with a tumor circumferential extent greater than 75 % was significantly higher in those with refractory stricture than in those without stricture (P = 0.001). Multivariate analysis adjusted for age, sex, history of radiation therapy, tumor location, and tumor diameter showed that a tumor circumferential extent greater than 75 % was an independent risk factor for refractory stricture (adjusted odds ratio [OR] 5.49 [95 %CI 1.91 – 15.84], P = 0.002). Major adverse events occurred in 3 patients (2.4 %): perforation during EBD in 2 patients and delayed perforation after EBD in 1 patient. The patient with delayed perforation underwent esophagectomy because of mediastinitis. Conclusions: A tumor circumferential extent greater than 75 % is an independent risk factor for refractory stricture despite steroid injections. The development of more extensive interventions is warranted to prevent refractory stricture. PMID:27004256

    Donor livers are offered to patients with the highest risk of death. How ascites may inform risk models to reduce liver transplant wait-list mortality is unclear. All adult candidates for primary liver transplantation for cirrhosis without exception points who were registered with the Organ Procurement and Transplantation Network from 2005 to 2007 comprised our study cohort. Using Cox models and advanced discriminative metrics, we evaluated the additional risk discrimination of moderate ascites over that of MELD and MELD plus serum sodium (MELDNa) alone to predict 90-day wait-list mortality with attention to geographic disparities. Additional analyses examined lower mortality risk candidates and those listed in high-demand, low-supply UNOS regions where accounting for ascites may impact wait-list mortality most significantly. Between 2005 and 2007, 18,124 subjects were listed for liver transplantation. Mortality was higher in patients with moderate ascites (15.5% vs. 6.0%, p<0.0001), a risk that persisted despite adjusting for MELD (HR 1.58, 95% CI 1.42–1.76) and MELDNa (HR 1.42, 95% CI 1.28–1.58). The effect of moderate ascites was more prominent when MELD<21, equating to 4.7 MELD units, or when MELDNa<21, equating to 3.5 MELDNa units. Wait-list mortality was higher in patients with moderate ascites listed in high-demand, limited-supply regions (25.8% vs. 17.5% at one-year, p<0.01). There was improvement in the overall risk model, particularly when MELD<21, with the addition of moderate ascites as measured by the C-index and IDI. Moderate ascites informs risk prediction, particularly when MELD<21 and in high-demand limited-supply regions. Under the MELD system, presence of moderate ascites should prompt clinicians to consider strategies to expand access to transplantation such as extended donor liver grafts. PMID:21280185

    Genetic selection based on rapid growth rates, improved feed conversion, and increased body weights has led to a predisposition to ascites in broiler populations. Sire-family selection was applied to a commercial elite line to produce divergent lines of ascites-resistant (RES) and ascites-susceptible (SUS) broilers by the 8th generation. One objective of this research was to determine the effects of hypobaric hypoxia on gut morphology in these genetic lines. In two separate trials, pedigree broiler chickens were randomly assigned to cages in a hypobaric chamber (simulated 2,900 m above sea level) or a matching local altitude chamber (390 m above sea level). Ascites incidence was characterized by heart enlargement and fluid accumulation in the abdominal cavity. At the end of the study on d 42, all surviving birds were killed and evaluated for the presence of ascites and 2-cm sections from the duodenum and lower ileum were collected from 5 chickens per line, per altitude for each trial for morphometric analysis. At a high altitude, ascites incidence was lower in the RES line (20.9 and 3.7%) than in the SUS line (86.4 and 66.9%, Trials 1 and 2, respectively). No ascites was observed at a local altitude. Under hypoxic conditions, duodenum villus surface area was higher (P < 0.05) in the RES line (181.3 +/- 16.8 and 219 +/- 10.9 microm) compared with the SUS line (130.1 +/- 10.5 and 134.3 +/- 9.3 microm; Trials 1 and 2, respectively). No differences in ileum villus morphology were observed for any of the parameters measured. The reduced surface area in the duodenum of birds selected for ascites susceptibility suggests reduced enteric function and may provide clues as to why these birds have increased incidence of ascites.

    During the course of ascites development in broilers, many factors can interact to cause hypoxia. To counteract hypoxia, birds with ascites develop greatly increased hematocrit and red cell counts. Increasing hematocrits result in more viscous blood. Prostaglandins are involved in the regulation of constriction and dilation of pulmonary blood vessels and in the formation of blood clots. Dietary aspirin, a prostaglandin inhibitor, was used in an attempt to promote vasodilation and inhibit blood clotting in broilers, with the objective of determining the effect of aspirin on ascites progression. The experimental design consisted of two trials with a total of 1,360, 1-d-old male broiler chicks, which were placed at either local altitude (390 m above sea level) or in a hypobaric chamber that simulated an altitude of 2,900 m above sea level. At each elevation, five dietary treatments were employed: [control, 0.025% crystalline acetylsalicylic acid (aspirin), 0.05% aspirin, 0.10% aspirin, and 0.20% aspirin]. Bird and feed weights were recorded weekly. At the end of 5 wk, blood samples and organ weights were collected, and all birds were examined for signs of ascites. In both trials, birds raised at high altitudes were significantly lighter, had a higher incidence of ascites, and had differences in hematology, compared with birds raised at local elevation. Only in Trial 2, however, did dietary aspirin appear to have any effect on ascites incidence. At the 0.20% aspirin level, a reduction in ascites incidence approached significance compared with controls (34% vs. 56%, P < or = 0.06). Unfortunately, birds fed 0.20% aspirin also were significantly (P < or = 0.01) lighter than controls. Because slowing growth rate is known to reduce ascites, this decrease in BW may have been partially responsible for any beneficial effect on ascites development and progression obtained through feeding aspirin.

    Purpose Natural killer T (NKT) cells recognize lipid antigen presented by CD1 molecules. NKT cells can both directly, through cytotoxicity, and indirectly, through activation of other effector cells, mediate anti-tumor immunity. However, it has been shown that tumor associated lipids are frequently shed into the tumor microenvironment, which can mediate immunosuppressive activity. Given that ovarian cancer associated ascites has been reported to have increased levels of gangliosides, we examined the effect of tumor associated and other ascites on CD1d-mediated antigen presentation to NKT cells. Experimental Design To investigate the effects of ascites on NKT cell activation, we pretreated CD1d-expressing cells with the ascites and measured their ability to stimulate cytokine production in NKT cells. To determine whether antigen processing or editing was necessary, CD1d-Ig-based artificial Antigen Presenting Cells (aAPC) were also incubated with ascites. In addition, to examine specificity, we analyzed whether ascites fluid could influence the activation of classical CD8+ T cells. Results Pretreatment of CD1d-expressing cells with ascites from the majority of patients inhibited the cells’ ability to stimulate/activate NKT cells in a dose-dependent manner. Ascites treatment also partially blocked the ability of α-GalCer loaded CD1d-Ig-based artificial Antigen Presenting Cells (aAPC) to activate NKT cells. In addition, our data demonstrate that treatment with ascites does not inhibit HLA-A2 mediated activation of classical CD8+ T cells. Conclusions Together, these data suggest that ovarian and other cancers may have developed immune evasion mechanisms specifically targeting the CD1/NKT cell system. PMID:19047090

    Ovarian cancer (OC) ascites consist in a proinflammatory tumor environment that is characterized by the presence of various cytokines, chemokines and growth factors. The presence of these inflammatory-related factors in ascites is associated with a more aggressive tumor phenotype. CCL18 is a member of CCL chemokines and its expression has been associated with poor prognosis in some cancers. However, its role in OC progression has not been established. Therefore, the aim of the current study was to elucidate the role of ascites CCL18 in OC progression. ELISA and tissue microarrays were used to assess CCL18 in ascites and phospho-Pyk2 expression in cancer tissues respectively. Cell migration was assessed using Boyden chambers. CCL18 and ascites signaling was examined in ovarian cancer cells utilizing siRNA and exogenous gene expression. Here, we show that CCL18 levels are markedly increased in advanced serous OC ascites relative to peritoneal effusions from women with benign conditions. Ascites and CCL18 dose-dependently enhanced the migration of OC cell lines CaOV3 and OVCAR3. CCL18 levels in ascites positively correlated with the ability of ascites to promote cell migration. CCL18 blocking antibodies significantly attenuated ascites-induced cell migration. Ascites and CCL18 stimulated the phosphorylation of proline-rich tyrosine kinase 2 (Pyk2) in CaOV3 and OVCAR3 cells. Most importantly, the expression of phosphorylated Pyk2 in serous OC tumors was associated with shorter progression-free survival. Furthermore, enforced expression of Pyk2 promoted tumor cell migration while siRNA-mediated downregulation of Pyk2 attenuated cell migration. Downregulation of Pyk2 markedly inhibited ascites and CCL18-induced cell migration. Taken together, our findings establish an important role for CCL18, as a component of ascites, in the migration of tumor cells and identify Pyk2 as prognostic factor and a critical downstream signaling pathway for ascites-induced OC cell migration.

    Disseminated intravascular coagulation is a rare complication of Kawasaki disease and appears in <0.1% of Kawasaki disease patients. We report a case of refractory Kawasaki disease complicated with disseminated intravascular coagulation and giant coronary aneurysm. A 5-month-old boy presented with Kawasaki disease with coagulopathy. Although the coagulopathy improved after fresh-frozen plasma and antithrombin-III administration, the fever persisted despite two rounds of intravenous immunoglobulin, along with intravenous methylprednisolone pulse therapy and infliximab administration. Despite all efforts to treatment, the patient had giant coronary aneurysms and died suddenly.

    Factors influencing the radiosensitivity of the newly established mouse ascites tumor TMT-3 line were studied. In vivo radiosensitivity of the tumor cells decreased with the progression of the growth phase in mice. Oxygen depletion was the major cause of the decreased radiosensitivity. Polarographic measurement of the oxygen dissolved in suspension of various cell densities suggested that high cell density such as in the ascites might well cause severe hypoxia. Humoral factors in the ascites and cell-to-cell contact had no effect on tumor cell radiosensitivity when the influence of the repair of potentially lethal damage was excluded.

  18. Role of malignant ascites on human mesothelial cells and their gene expression profiles

    PubMed Central

    2014-01-01

    Background Malignant ascites is often present at diagnostic in women with advanced ovarian cancer (OC) and its presence is associated with a worse outcome. Human peritoneal mesothelial cells (HPMCs) are key components of malignant ascites. Although the interplay between HPMCs and OC cells is believed to be critical for tumor progression, it has not been well characterized. The purpose of this study was to assess the effect of ascites on HPMCs and clarify the role of HPMCs in OC progression. Methods Human OC ascites and benign peritoneal fluids were assessed for their ability to stimulate HPMC proliferation. Conditioned medium from ascites- and benign fluid-stimulated HPMCs were compared for their ability to attenuate apoptosis induced by TNF-related apoptosis-inducing ligand (TRAIL). We conducted a comparative analysis of global expression changes in ascites-stimulated HPMCs using Agilent oligonucleotide microarrays. Results As compared to benign peritoneal fluids, malignant ascites stimulated the proliferation of HPMCs. TRAIL-induced apoptosis was attenuated in OC cells exposed to conditioned medium from ascites-stimulated HPMCs as compared to OC cells exposed to conditioned medium from benign fluid-stimulated HPMCs. A total of 649 genes were differentially expressed in ascites-stimulated HPMCs. Based on a ratio of more than 1.5-fold and a P < 0.05, 484 genes were up-regulated and 165 genes were down-regulated in ascites-exposed HPMCs. Stimulation of HPMCs with OC ascites resulted in differential expression of genes mainly associated with the regulation of cell growth and proliferation, cell death, cell cycle and cell assembly and organization, compared to benign peritoneal fluids. Top networks up-regulated by OC ascites included Akt and NF-κB survival pathways whereas vascular endothelial growth factor (VEGF) pathway was down-regulated. Conclusions The results of this study not only provide evidence supporting the importance of the interplay between cancer

    Malignant ascites presents a considerable clinical challenge to the management of ovarian cancer, but also provides a wealth of opportunities for translational research. The accessibility of ascitic fluid and its cellular components make it an excellent source of tumour tissue for the investigation of prognostic and predictive biomarkers, pharmacodynamic markers and for molecular profiling analysis. In this Opinion article, we discuss recent advances in our understanding of its pathophysiology, the development of new methods to characterize its molecular features and how these findings can be used to improve the treatment of malignant ascites, particularly in the context of ovarian cancer.

    Launch Pads 39A and 39B currently use refractory material (Fondu Fyre) in the flame trenches. This material was initially approved for the Saturn program. This material had a lifetime of 10 years according to the manufacturer, and it has been used for over 40 years. As a consequence, the Fondu Fyre at Launch Complex 39 requires repair subsequent to almost every launch. A review of the literature indicates that the gunned Fondu Fyre refractory product (WA-1G) was never tested prior to use. With the recent severe damage to the flame trenches, a new refractory material is sought to replace Fondu Fyre. In order to replace Fondu Fyre, a methodology to test and evaluate refractory products was developed. This paper outlines this methodology and discusses current testing requirements, as well as the laboratory testing that might be required. Furthermore, this report points out the necessity for subscale testing, the locations where this testing can be performed, and the parameters that will be necessary to qualify a product. The goal is to identify a more durable refractory material that has physical, chemical, and thermal properties suitable to withstand the harsh environment of the launch pads at KSC.

Patients and Methods Twenty-six patients (5 females, 21 males; mean age 54.6 years) were treated using a low-profile 6F self-expanding sinus-SuperFlex-Visual stent system. The indication for TIPSS creation was refractory bleeding in 9 of the 26 patients, refractory ascites in 18 patients, and acute thrombosis of the portal vein confluence in one patient. Portosystemic pressure gradients before and after TIPSS, periprocedural and long-term complications, and the time to orthotopic liver transplantation (OLT) or death were recorded. Results The portosystemic pressure gradient was significantly reduced, from 20.9 ± 6.3 mmHg before to 8.2 ± 2.3 mmHg after TIPSS creation (P < 0.001). Procedure-related complications included acute tract occlusion (n = 2), liver hematoma (n = 1), hepatic encephalopathy (n = 1), and cardiac failure (n = 1). Three of the 26 patients had late-onset TIPSS occlusion (at 12, 12, and 39 months after TIPSS creation). Three patients died within one week after the procedure due to their poor general condition (multiorgan failure, acute respiratory distress syndrome, necrotizing pancreatitis, and aspiration pneumonia). Another four patients succumbed to their underlying advanced liver disease within one year after TIPSS insertion. Seven patients underwent OLT at a mean time of 9.4 months after TIPSS creation. Conclusion The sinus-SuperFlex-Visual stent system can be safely deployed as a TIPSS device. The pressure gradient reduction was clinically sufficient to treat the patients’ symptoms, and periprocedural complications were due to the TIPSS

    We report a new case of idiopathic hypereosinophilic syndrome with multivisceral digestive failure. After an erroneous diagnosis of pancreatic cancer, the pathological examination of pancreaticoduodenectomy specimen demonstrated pancreatic fibrosis with eosinophilic infiltration without gastritis or duodenitis. The diagnosis of idiopathic hypereosinophilic syndrome was made three months later upon the classical criteria: a) blood eosinophilia of 1.5 G/L or more, persisting for more than 6 months; b) lack of evidence for any other recognised cause of eosinophilia: c) multiple organ systemic involvement: rheumatologic, cutaneous and digestive (pancreatitis, ascites and diarrhoea): d) previous history of allergic disease and increased plasmatic IgE levels; e) absence of leukemic markers. This case emphasises the difficulty in classifying eosinophilic infiltration of the gut and the possibility of transitional forms between eosinophilic gastro-enteritis and idiopathic hypereosinophilic syndrome. We argue that in case of eosinophilic infiltration of the gut, systematic research of multiple organ systemic involvement is mandatory.

    Cell killing and the induction of mutation to thioguanine resistance were measured after exposure of Ehrlich ascites tumor cells to 150-kV X rays and /sup 241/Am ..cap alpha.. particles. The curve describing the induction of mutations was almost linear after exposure to ..cap alpha.. particles but upward bending after exposure to X rays, apparently reaching a final slope similar to that obtained after exposure to ..cap alpha.. particles. The number of mutants induced per viable cell by ..cap alpha.. particles at a given level of cell killing was similar to that induced by X rays. The RBE values obtained for cell killing and the induction of mutations are compared with each other, and the possible involvement of repair processes in determining the RBE is discussed.

    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 /sup 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.

    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.

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

    Ascites with unknown cause remains a diagnostic challenge, which needs novel noninvasive biomarkers for the precise diagnosis. We aimed to evaluate the ascitic fluid and serum C-reactive protein (CRP) and vascular endothelial growth factor (VEGF) as diagnostic markers in the differential diagnosis of malignant and benign ascites. In this prospective work, 315 consecutive patients with ascites were studied. Ascitic fluid and serum levels of CRP and VEGF were evaluated by using an enzyme-linked immunosorbent assay. Patients were divided into a benign ascites group (group 1) (n = 256) and a malignant ascites group (group 2) (n = 59). Ascitic and serum CRP were significantly elevated in malignant ascites than benign ascites group [5.08 (3.62-6.58) vs. 1.82 (0.64-3.86) ng/ml; P < 0.001 and 12.7 (8.55-17.05) vs. 5.94 (2.57-10.64) ng/ml; P < 0.001], respectively. Ascitic and serum VEGF were significantly increased in malignant ascites than benign ascites patients [0.68 (0.39-0.96) vs. 0.41 (0.25-0.83) ng/ml; P < 0.001 and 0.74 (0.41-1.08) vs. 0.54 (0.23-0.86) ng/ml; P < 0.001], respectively. At a cutoff value of 7.3 and 0.63 ng/ml, serum CRP and VEGF had specificity (77.3 and 89.5 %) and sensitivity (83.1 and 94.9 %) for detecting malignant ascites [area under the curve (AUC) 0.821, 0.921], respectively. At a cutoff value of 2.5 and 0.57 ng/ml, ascitic CRP and VEGF had specificity (81.6 and 85.5 %) and sensitivity (84.7 and 91.5 %) for detecting malignant ascites (AUC 0.842, 0.894), respectively. Elevated ascitic fluid and serum CRP and VEGF values were related to the malignant ascites.

    Liver transplantation preserving the retrohepatic inferior 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.

    Previously, we reported a genome wide association study (GWAS) that had shown association of a region between 11.8 and 13.6 Mbp on chromosome 9 with ascites phenotype in broilers. We had used microsatellite loci to demonstrate an association of particular genotypes for this region with ascites in experimental ascites lines and commercial broiler breeder lines. We identified two potential candidate genes, AGTR1 and UTS2D, within that chromosomal region for mediating the quantitative effect. We have now extended our analysis using SNPs for these genes to assess association with resistance or susceptibility to ascites in these same broiler lines. Surprisingly, in contrast to our previous GWAS and microsatellite data for this region, we find no association of the SNP genotypes or haplotypes in the region suggesting that the two genes might have limited association with the disease phenotype. © 2016 Poultry Science Association Inc.

    A genome-wide SNP survey was used to identify chromosomal regions that showed linkage disequilibrium with respect to ascites susceptibility and ventricular hypertrophy in an F2 cross between previously described ascites-resistant and -susceptible lines. Variable number tandem repeats were used to obtain genotype data to further characterize these regions. A region on chromosome 9 (12 to 13 Mbp in 2011 assembly) shows association with ascites in the ascites lines and in several commercial broiler breeder lines with a significant sex effect. There are 2 candidate genes, AGTR1 (an angiotensin II type 1 receptor) and UTS2D (urotensin 2 domain containing), in this region that have been associated with hypertension and hypoxic response in mammals.

    A 68-year-old woman presented to our hospital with abdominal fullness. Computed tomography(CT)revealed ascites and massive tumors in the abdominal cavity. She was diagnosed with ascending colon cancer with peritoneal dissemination and ovarian metastasis. After ileostomy, panitumumab plus mFOLFOX6 therapy was initiated, but it was discontinued due to adverse events. As the ascites rapidly increased, her chemotherapy was changed to bevacizumab(BV)plus FOLFIRI. BV combination therapy resulted in a dramatic decrease in ascites and improved her quality of life, whereas the therapy did not reduce the primary and metastatic lesions. Our case suggested that BV could decrease ascites by inhibiting vascular endothelial growth factor(VEGF)-induced vascular permeability.

    Epithelial ovarian cancer consists of multiple histotypes differing in etiology and clinical course. The most prevalent histotype is high-grade serous ovarian cancer (HGSOC), which often presents at an advanced stage frequently accompanied with high-volume ascites. While some studies suggest that ascites is associated with poor clinical outcome, most reports have not differentiated between histological subtypes or tumor grade. We compared genome-wide gene expression profiles from a discovery cohort of ten patients diagnosed with stages III-IV HGSOC with high-volume ascites and nine patients with low-volume ascites. An upregulation of immune response genes was detected in tumors from patients presenting with low-volume ascites relative to those with high-volume ascites. Immunohistochemical studies performed on tissue microarrays confirmed higher expression of proteins encoded by immune response genes and increased tumorinfiltrating cells in tumors associated with low-volume ascites. Comparison of 149 advanced-stage HGSOC cases with differential ascites volume at time of primary surgery indicated low-volume ascites correlated with better surgical outcome and longer overall survival. These findings suggest that advanced stage HGSOC presenting with low-volume ascites reflects a unique subgroup of HGSOC, which is associated with upregulation of immune related genes, more abundant tumor infiltrating cells and better clinical outcomes.

    Ascites is a metabolic disorder of modern broilers that is distinguished by cardiopulmonary insufficiency in the face of intense oxygen demands of rapidly growing tissues. Broilers with ascites exhibit sustained elevation of pulmonary arterial pressure and right ventricular hypertrophy, the end result of which is heart failure. It has been shown that mitochondrial function is impaired in broilers with ascites. In the current study, mitochondrial matrix protein levels were compared between ascites-resistant line broilers and ascites-susceptible line broilers with and without ascites using two-dimensional (2-D) gel electrophoresis. One hundred seventy-two protein spots were detected on the gels, and 9 of the spots were present at different levels in the 4 groups of broilers. These 9 protein spots were selected for identification by mass spectrometry. Two of the spots were found to contain single mitochondrial matrix proteins. Both mitochondrial matrix proteins, the dihydrolipoamide succinyltransferase component of the 2-oxoglutarate dehydrogenase complex and the alpha-subunit of mitochondrial trifunctional enzyme, were present at higher levels in ascites-resistant line broilers with ascites in the present study. The elevated levels of 2 key proteins in aerobic metabolism in ascites-resistant line broilers with ascites observed in the present study suggests that the mitochondria of broilers with this disease may respond inappropriately to hypoxia.

The diagnosis of SLE was based on the presence of: malar rash, oral ulcers, thrombocytopenia, antinuclear antibodies, IgM anticardiolipin antibody, and lupus anticoagulant. Renal and liver diseases were ruled out. The PLE diagnosis was confirmed with fecal alpha 1-antitrypsin clearance. The PLE was refractory to different lines of immunosuppressive agents like glucocorticoids, cyclophosphamide, azathioprine, and cyclosporine, showing a satisfactory and sustained response with rituximab, allowing steroid sparing and long term remission.

    Background Intractable ascites is one of the causes of graft loss after adult-to-adult living donor liver transplantation (LDLT) using a small graft. Identification of factors associated with increasing posttransplant ascites has important implications for prevention and treatment. Methods All 59 consecutive adult patients who underwent left lobe LDLT without portal inflow modulation between October 2002 and February 2016 were prospectively enrolled. Factors associated with the average daily amount of ascites for 2 weeks after LDLT were assessed. Results The median daily amount of ascites during the 2 weeks was 1052 mL (range, 52-3480 mL). Although 16 of the 59 patients developed intractable ascites, exceeding 1500 mL daily (massive ascites group), the remaining 43 patients produced less than 1500 mL of ascites daily (nonmassive ascites group). The presence of pretransplant ascites (P = 0.001), albumin (P = 0.011), albumin/globulin ratio (P = 0.026), cold ischemia time (P = 0.004), operation time (P = 0.022), and pretransplant portal vein pressure (PVP) (P = 0.047) differed significantly between the 2 groups. Neither posttransplant PVP nor portal vein flow differed between the 2 groups. The variables associated with intractable ascites that remained significant after logistic regression analysis were pretransplant PVP (P = 0.047) and cold ischemia time (P = 0.049). After appropriate fluid resuscitation for intractable ascites, 58 (98%) of the 59 recipients were discharged from hospital after removal of the indwelling drains. Conclusions It is important to shorten the scold ischemia time to reduce massive ascites after LDLT. Pretransplant portal hypertension is more closely associated with ascites production than posttransplant hemodynamic status. PMID:28361122

    Cardiac ascites is frequently diagnosed, but there is a paucity of data regarding the predictors for its formation. In a group of patients with heart failure referred for orthotopic heart transplantation and ventricular assist device (VAD) placement, we attempted to identify patient characteristics and predictors associated with the development of ascites. Long-term outcomes of patients with and without ascites were examined. Patients were divided into 2 groups based on the presence or absence of significant ascites on imaging. Demographic information, laboratory values, and results of transthoracic echocardiograms and right-sided cardiac catheterizations were compared between the groups. Of the 196 patients, 29 patients (15%) had significant ascites. The group with significant ascites had higher mean creatinine (2.3 vs 1.6 mg/dl, p = 0.03). On transthoracic echocardiograms, the group with significant ascites had more severe right ventricular dilation (p = 0.03) and tricuspid valve regurgitation (p <0.01). On right-sided cardiac catheterizations, the group with significant ascites had higher mean right atrial (RA) pressure (17 vs 13 mm Hg, p = 0.01). There was no difference in pulmonary capillary wedge pressure between the groups (22 vs 23 mm Hg, p = 0.57). No threshold value of RA pressure was identified for the development of significant ascites. The presence of significant ascites was associated with decreased overall survival (p <0.01). In conclusion, impaired renal function and elevated right-sided cardiac pressures were more commonly seen in the group with significant ascites. No minimum RA pressure elevation was required for significant ascites formation. The presence of significant ascites was correlated with higher mortality. Copyright © 2015 Elsevier Inc.

    The histopathologic changes of the peritoneum of the hemidiaphragm were studied in 30 patients with schistosomal liver disease and compared with ten control subjects. The diaphragmatic peritoneum of patients with ascites was markedly thickened with infiltration of inflammatory cells and collagen bundles resembling the interstitial changes of peripheral lymphedema. Obliteration of diaphragmatic lymphatic stomata with restricted lymph flow as well as excess lymph formation from portal hypertension are both major factors in the magnitude and intractability of ascites associated with schistosomal hepatic fibrosis.

    The objective of the present study was to use bivariate mixture models to study the relationships between body weight (BW) and ascites indicator traits. Existing data were used from an experiment in which birds were housed in 2 groups under different climate conditions. In the first group, BW, the ratio of right ventricular weight to total ventricular weight (RV:TV), and hematocrit value (HCT) were measured in 4,202 broilers under cold conditions; in the second group, the same traits were measured in 795 birds under normal temperature conditions. Cold-stress conditions were applied to identify individuals that were susceptible to ascites. The RV:TV and HCT were approximately normally distributed under normal temperature conditions, whereas the distributions of these traits were skewed under cold temperature conditions, suggesting different underlying distributions. Fitting a bivariate mixture model to the observations showed that there was only one homogeneous population for ascites traits under normal temperature conditions, whereas there was a mixture of (2) distributions under cold conditions. One distribution contained nonascitic birds and the other distribution contained ascitic birds. In the distribution of nonascitic birds, the inferred phenotypic correlations (phenotypic correlations with 2 distinguishing underlying distributions) of BW with RV:TV and HCT were close to zero (0.10 and -0.07, respectively), whereas in the distribution of ascitic birds, the inferred phenotypic correlations of BW with RV:TV and HCT were negative (-0.39 and -0.4, respectively). The negative inferred correlations of BW with RV:TV and HCT in the distribution of ascitic birds resulted in negative overall correlations (correlations without 2 distinguishing distributions) of BW with RV:TV (-0.30) and HCT (-0.37) under cold conditions. The present results indicate that the overall correlations between BW and ascites traits are dependent on the relative frequency of ascitic and

    We describe the strategy, which allows curing experimental mice engrafted with Krebs-2 ascites. The strategy is based on the facts that i) Krebs-2 tumor-initiating stem cells (TISCs) are naturally capable of internalizing fragments of extracellular double-stranded DNA (dsDNA); ii) upon delivery into TISCs, these dsDNA fragments interfere with the on-going DNA repair process so that TISCs either die or lose their tumorigenic potential. The following 3-step regimen of therapeutic procedures leading to eradication of Krebs-2 ascites is considered. Firstly, three timed injections of cyclophosphamide (CP) exactly matching the interstrand cross-link (ICL) repair phases that lead to synchronization of ascites cells in late S/G2/M. Secondly, additional treatment of ascites 18 hours post each CP injection (at NER/HR transition timepoint) with a composite dsDNA-based preparation interfering with the NER and HR repair pathways, so that tumorigenic properties of ascites cells are compromised. Thirdly, final treatment of mice with a combination of CP and dsDNA injections as ascites cells undergo apoptotic destruction, and the surviving TAMRA+ TISCs arrested in late S/G2/M phases massively enter into G1/S, when they regain sensitivity to CP+dsDNA treatment. Thus, this regimen assures that no viable cells, particularly Krebs-2 TISCs, remain. PMID:26872383

    Although undifferentiated tumors are the most lethal among all ovarian cancer histotypes, the exact reasons for this situation are unclear. This report was aimed at investigating whether the high aggressiveness of undifferentiated ovarian cancer may be associated with a biochemical composition of malignant ascites accumulating in the peritoneal cavity. We analyzed ascites from patients with undifferentiated, high-grade serous, endometrioid and clear-cell ovarian cancers, and from non-cancerous patients with respect to a group of soluble agents involved in cancer cell progression. Moreover, the effect of these fluids on proliferation and migration of ovarian cancer cells (A2780, OVCAR-3 and SKOV-3) was evaluated. The study showed that the level of all tested proteins in malignant ascites was higher than in the benign fluids. Concentration of 9/11 agents (CCL2, CXCL1, CXCL5, CXCL8, CXCL12, HGF, PAI-1, TGF-β1 and VEGF) was the greatest in the fluids from undifferentiated cancer, while the level of remaining 2 (IL-6 and uPA) was the highest in ascites from serous carcinoma. Proliferation of cancer cells was the most effective when they were subjected to ascites from patients with undifferentiated and serous cancer, whereas the migration was the highest in the case of undifferentiated tumors. Our findings indicate that the aggressiveness of undifferentiated ovarian tumors may be associated with the composition of malignant ascites, in particular the concentration of specific proinflammatory, cancer-promoting agents.

    We investigated the therapeutic role of the herbal combination Euphorbia kansui (GS) and Glycyrrhiza (GC) in ascites during hepatocellular carcinoma (HCC). The AVPR2 and AQP2 expression in kidney tissues of ascites mice in different groups was determined by immunohistochemistry, Western blot, and real-time PCR analyses. When the dose of GS was less than 0.70 g/kg at a ratio of GC : GS not exceeding 0.4 : 1, the combination of GS and GC exhibited synergistic effects on HCC ascites and significantly elevated the expression levels of AVPR2 and AQP2 (all P < 0.05). On the contrary, when GS ≥ 0.93 g/kg and GC ≥ 1.03 g/kg with the GC-to-GS ratio exceeding 1.11 : 1, the combination of GS and GC displayed antagonistic effects on HCC ascites and dramatically reduced the expression levels of AVPR2 and AQP2 (all P < 0.05). Furthermore, the administration of herbal pair GS and GC at different ratios did not exacerbate the pathological changes in liver and kidney tissues of HCC ascites mice. The different combinations of GS and GC exerted synergistic or antagonistic effects on HCC ascites, partially by regulating the expression of AVPR2 and AQP2. PMID:27247609

    Background Malignant ascites is a pathological condition caused by intra- or extra-abdominal disseminated cancer. The object of treatment is palliation. In search of an effective and minimally invasive palliative treatment of malignant ascites placement of a permanent intra peritoneal catheter has been suggested. Purpose To evaluate our experiences with treatment of malignant ascites by implantation of a permanent PleurX catheter. Material and Methods A retrospective study was conducted, comprising 20 consecutive patients with terminal cancer, who had a permanent PleurX catheter implanted because of malignant ascites in the period from February to November 2014. Using the patients’ medical records, we retrieved data on patients and procedures. Results The technical success rate was 100%. Catheter patency was 95.2%, one catheter was removed due to dislocation. Ten patients (50.0%) experienced minor adverse events. No procedural difficulties were reported and there was no need for additional treatment of malignant ascites after catheter implantation. Median residual survival after catheter implantation was 27 days. Conclusion Implantation of a permanent PleurX catheter is a minimally invasive and effective procedure with only minor adverse events and a high rate of catheter patency in patients with malignant ascites caused by terminal cancer disease.

    Chronic refractory cough (CRC) is defined as a cough that persists despite guideline based treatment. It is seen in 20-46% of patients presenting to specialist cough clinics and it has a substantial impact on quality of life and healthcare utilization. Several terms have been used to describe this condition, including the recently introduced term cough hypersensitivity syndrome. Key symptoms include a dry irritated cough localized around the laryngeal region. Symptoms are not restricted to cough and can include globus, dyspnea, and dysphonia. Chronic refractory cough has factors in common with laryngeal hypersensitivity syndromes and chronic pain syndromes, and these similarities help to shed light on the pathophysiology of the condition. Its pathophysiology is complex and includes cough reflex sensitivity, central sensitization, peripheral sensitization, and paradoxical vocal fold movement. Chronic refractory cough often occurs after a viral infection. The diagnosis is made once the main diseases that cause chronic cough have been excluded (or treated) and cough remains refractory to medical treatment. Several treatments have been developed over the past decade. These include speech pathology interventions using techniques adapted from the treatment of hyperfunctional voice disorders, as well as the use of centrally acting neuromodulators such as gabapentin and pregabalin. Potential new treatments in development also show promise.

    Refractory coeliac disease (RCD) is a recognised complication, albeit very rare, of coeliac disease (CD). This condition is described when individuals with CD continue to experience enteropathy and subsequent or ongoing malabsorption despite strict adherence to a diet devoid of gluten for at least 12 months and when all other causes mimicking this condition are excluded. Depending on the T-cell morphology and T-cell receptor (TCR) clonality at the β/γ loci, RCD can be subdivided into type 1 (normal intra-epithelial lymphocyte morphology, polyclonal TCR population) and type 2 (aberrant IELs with clonal TCR). It is important to differentiate between the two types as type 1 has an 80% survival rate and is managed with strict nutritional and pharmacological management. RCD type 2 on the other hand has a 5-year mortality of 50% and can be complicated by ulcerative jejunitis or enteropathy-associated T-cell lymphoma (EATL). Management of RCD type 2 has challenged many experts, and different treatment approaches have been adopted with variable results. Some of these treatments include immunomodulation with azathioprine and steroids, methotrexate, cyclosporine, alemtuzumab (an anti CD-52 monoclonal antibody), and cladribine or fludarabine sometimes with autologous stem cell transplantation. In this article, we summarise the management approach to patients with RCD type 2. PMID:27803799

    Transcoelomic route is the most common and the earliest route of metastasis, causing the ascites formation in advanced epithelial ovarian cancer (EOC). We demonstrated that interleukin 6 (IL-6) is enriched in the malignant ascites from patients with ovarian cancer, which enhanced invasive properties of EOC cells. Interestingly, the expression of IL-6R on cell membrane of EOC cells correlated with ascites-induced invasion. Selective knockdown of IL-6R or inhibition with IL-6 neutralizing antibody, suppressed the stimulatory effects of ascites on EOC invasion. Moreover, the ascites treatment induced the phosphorylation of JAK2-STAT3 and use of selective inhibitors of JAK2 and STAT3, blocked the expression of epithelial-mesenchymal transition related proteins in parallel with the suppression of EOC invasion. Thus, IL-6/IL-6R mediated JAK2-STAT3 signaling pathway could be a promising therapeutic target for anticancer therapy in ovarian cancer patients with ascites. PMID:27825119

    Tramadol is a weak opioid analgesic indicated for the treatment of moderate to severe pain. Tramadol intoxication can be lethal, and this drug is frequently involved in voluntary overdose. Classically, tramadol intoxication is associated with neurological and respiratory side effects. In contrast, cardiac effects are poorly documented in the literature. We report a case of severe tramadol intoxication, with plasma concentration 20 times the toxic threshold, complicated by refractory cardiogenic shock, successfully treated by extra corporeal life support (ECLS) with a favorable cardiac outcome and ECLS weaning at day 10. Seizure, clonus, and nonreactive mydriasis were present during 4 days, and complete awakening was delayed to day 15. Poisoning caused by high doses of tramadol can lead to refractory cardiogenic shock, and ECLS can be considered as effective rescue therapy in this context.

    Giant cell arteritis is a primary large-vessel vasculitis characterized by an arterial wall inflammation associated with intimal hyperplasia leading to arterial occlusion. Glucocorticoids remain the mainstay of giant cell arteritis treatment. However, relapses and glucocorticoid-related complications are frequent and therapeutic options for refractory giant cell arteritis are quite limited. Like tumor necrosis factor-α and interleukin-6, interleukin-1β is also highly expressed in inflamed arterial walls of patients with giant cell arteritis and may contribute in the pathogenesis of this disease. We report treatment of three cases of refractory giant cell arteritis successfully treated with anakinra, an interleukin-1 blockade therapy. Anakinra was effective for all patients, yielding improvement in their inflammation biomarkers and/or in their symptoms, as well as a disappearance of arterial inflammation in PET/CT for two of them.

    Ehrlich tumor is a mammary adenocarcinoma with aggressive behavior. Inoculated in mice peritoneal cavity, the Ehrlich tumor grows in ascitic form (EAT). Since inflammation modulates tumor progression we further investigated the inflammatory response during EAT growth. Balb/C mice were intraperitoneal inoculated with 5×10(5) Ehrlich cells and after every 2days, blood samples were collected for hemoglobin, hematocrit, platelets and leukocytes counts. The ascitic fluid was collected for protein concentration and cell count. Phenotype analysis of the peritoneal cells was made by FACS, prostaglandin E2 (PGE2) and cytokines by ELISA, nitric oxide (NO) by nitrate conversion protocol, and cyclooxygenase-1 (COX1), COX2 and inducible nitric oxide synthase (iNOS) by immunoblotting. Following EAT inoculation into the peritoneal cavity there was a rapid increase in ascitis volume and protein concentration. The cell number in ascitis remained stable until day 8 (lag phase) followed by a sharp increase. As tumor progressed, blood leukocytes increased and erythrocyte decreased. Phenotypic analysis showed that during the lag phase the percentage of F4/80(+) cells remained similar to control levels and around 7% of this population was also positive for the GR1 marker. These double-positive cells (probably inflammatory monocytes) markedly increased at day 6. The percentage of F4/80-GR1(+)cells (probably neutrophils) was low and did not significantly vary during tumor progression. CD4(+) and CD8(+) cells were not detected in the time points analyzed. iNOS and COX1 expression increased after day 2 reaching peak levels on day 10. COX2 enzyme expression did not change significantly over time. Sustained increase in PGE2 and NO levels was observed. IL-10 and MCP-1 peaked at day 14 and IL-1β increased progressively till day 10. IFN-γ levels were low till day 10, increasing progressively after that. These data extended the characterization of the inflammatory response during Ehrlich

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

    The disclosure provides a refractory brick system comprising a chromia refractory brick for operation in the slagging environment of an air-cooled gasifier. The chromia refractory brick comprises a ceramically-bonded porous chromia refractory having a porosity greater than 9% and having carbon deposits residing within the pores. The brick may be further comprised of Al.sub.2O.sub.3. The air-cooled gasifier generates a liquefied slag in contact with the refractory brick and generally operates at temperatures between 1250.degree. C. and 1575.degree. C. and pressures between 300 psi to 1000 psi, with oxygen partial pressures generally between 10.sup.-4 and 10.sup.-10 atm. The refractory brick performs without substantial chromium carbide or chromium metal formation in the low oxygen partial pressure environment. The inclusion of carbon without chromium carbide formation provides for significant mitigation of slag penetration and significantly reduced refractory wear.

    Splanchnic arterial vasodilatation has been causally related with hyperdynamic circulation and impaired natriuresis in advanced cirrhosis and has also been suggested to be responsible for the subtle sodium retention in pre-ascitic cirrhosis. This study evaluated the effects of a 7-day treatment with the alpha1-adrenergic agonist midodrine in non-azotemic cirrhotic patients with and without ascites. Thirty-nine cirrhotic patients were studied at baseline and 7 days after administration of oral midodrine 10mg, t.i.d. (11 without and 12 with ascites) or placebo (8 without and 8 with ascites). A significant increase in urine sodium excretion was noted after midodrine administration in patients without and with ascites, in line with significant increases in mean arterial pressure and systemic vascular resistance, and significant decreases in cardiac output and heart rate. Significant increases in glomerular filtration rate, filtration fraction, and urine volume and significant decreases in plasma renin activity and aldosterone were observed in patients with ascites. Placebo had no effect in any study group. The administration of midodrine for 7 days improves systemic haemodynamics and sodium excretion in non-azotemic cirrhotic patients without or with ascites. In patients with ascites, but not in those without ascites, these effects are associated with a suppression of the activity of the renin-angiotensin-aldosterone system, suggesting that the increase in natriuresis is related to the improvement in the effective arterial blood volume.

    DNA from Ehrlich ascites tumor cells is nicked or gapped by a reaction which is induced by proteases such as autodigested pronase, proteinase K, trypsin, chymotrypsin and subtilisin. The cleavage of the protease-sensitive sites is inhibited by protease inhibitors. The nicks or gaps induced by proteases can be demonstrated by nuclease S1 sensitivity of native DNA and by a change of the sedimentation rate of alkali-denatured DNA. The limit size of denatured DNA released after optimal protease treatment is 8.5 x 10(6) daltons (27 kilo bases). The molecular weight of the native DNA pieces released after nuclease S1 degradation of DNA containing the protease-induced nicks or gaps is in the same order indicating that the protease-sensitive sites are alternatively arranged on the opposite DNA strands at an average distance of 13.5 kilo base pairs. Since the protease-induced nicks or gaps in phosphatase-treated DNA are not attacked by Escherichia coli polymerase I, one or both ends liberated by the protease treatment must be blocked by a material other than phosphate groups. The results are most compatible with peptide/protein linkers joining adjacent single-strand DNA subunits. Alternative explanations such as alkali-stable RNA linkers, protein-protected RNA linkers, site-specific nuclease contaminations in the protease preparations or cellular nucleases activated by the protease treatment are eliminated by the results presented in this paper.

    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.

    Background Refractory anemia with ring sideroblasts associated with marked thrombocytosis was proposed as a provisional entity in the 2001 World Health Organization classification of myeloid neoplasms and also in the 2008 version, but its existence as a single entity is contested. We wish to define the clinical features of this rare myelodysplastic/myeloproliferative neoplasm and to compare its clinical outcome with that of refractory anemia with ring sideroblasts and essential thrombocythemia. Design and Methods We conducted a collaborative retrospective study across Europe. Our database included 200 patients diagnosed with refractory anemia with ring sideroblasts and marked thrombocytosis. For each of these patients, each patient diagnosed with refractory anemia with ring sideroblasts was matched for age and sex. At the same time, a cohort of 454 patients with essential thrombocythemia was used to compare outcomes of the two diseases. Results In patients with refractory anemia with ring sideroblasts and marked thrombocytosis, depending on the Janus Kinase 2 V617F mutational status (positive or negative) or platelet threshold (over or below 600×109/L), no difference in survival was noted. However, these patients had shorter overall survival and leukemia-free survival with a lower risk of thrombotic complications than did patients with essential thrombocythemia (P<0.001) but better survival (P<0.001) and a higher risk of thrombosis (P=0.039) than patients with refractory anemia with ring sideroblasts. Conclusions The clinical course of refractory anemia with ring sideroblasts and marked thrombocytosis is better than that of refractory anemia with ring sideroblasts and worse than that of essential thrombocythemia. The higher risk of thrombotic events in this disorder suggests that anti-platelet therapy might be considered in this subset of patients. From a clinical point of view, it appears to be important to consider refractory anemia with ring sideroblasts and

A proportion of myasthenia gravis patients are classified as refractory due to non responsiveness to conventional treatment. This retrospective study was done to evaluate clinical profile, epidemiological, laboratory, and features of patients with MG and mode of management using rituximab and complications. Methods: Data of myasthenia gravis patients admitted or presented to outpatient department (previous medical records) with MG between January 2008 and January 2016 were included. A total of 512 patients fulfilled the clinical and diagnostic criteria of myasthenia gravis of which 76 patients met the diagnostic certainty for refractory myasthenia gravis and were evaluated. Results: Out of 76 refractory MG patients, 53 (69.73%) patients fulfilled all the three defined criteria. The median age of onset of the refractory MG group was 36 years with a range of 27–53 years. In our study 25 patients (32.89%) belonged to the age group of 21–30 years. Anti-MuSK antibodies were positive in 8 non-refractory MG patients (2.06%) and 36 refractory MG patients (47.36%). Mean HbA1C was found to be 8.6±2.33. The dose of administered prednisone decreased by a mean of 59.7% (p=3.3x10–8) to 94.6% (p=2.2x10–14) after the third cycle of rituximab treatment. Conclusion: The refractory MG patients are most commonly female with an early age of onset, anti-MuSK antibodies, and thymomas. Refractory MG patients have higher prevalence and poor control (HbA1C >8%) of diabetes mellitus and dyslipidemia probably due to increased steroid usage. Rituximab is very efficient in treatment of refractory MG with adverse effects being low. PMID:27790079

    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.

    Upon hemolysis extracellular hemoglobin causes oxidative stress and cytotoxicity due to its peroxidase activity. Extracellular hemoglobin may release free hemin, which increases vascular permeability, leukocyte recruitment, and adhesion molecule expression. Pancreatitis-associated ascitic fluid is reddish and may contain extracellular hemoglobin. Our aim has been to determine the role of extracellular hemoglobin in the local and systemic inflammatory response during severe acute pancreatitis in rats. To this end we studied taurocholate-induced necrotizing pancreatitis in rats. First, extracellular hemoglobin in ascites and plasma was quantified and the hemolytic action of ascitic fluid was tested. Second, we assessed whether peritoneal lavage prevented the increase in extracellular hemoglobin in plasma during pancreatitis. Third, hemoglobin was purified from rat erythrocytes and administered intraperitoneally to assess the local and systemic effects of ascitic-associated extracellular hemoglobin during acute pancreatitis. Extracellular hemoglobin and hemin levels markedly increased in ascitic fluid and plasma during necrotizing pancreatitis. Peroxidase activity was very high in ascites. The peritoneal lavage abrogated the increase in extracellular hemoglobin in plasma. The administration of extracellular hemoglobin enhanced ascites; dramatically increased abdominal fat necrosis; upregulated tumor necrosis factor-α, interleukin-1β, and interleukin-6 gene expression; and decreased expression of interleukin-10 in abdominal adipose tissue during pancreatitis. Extracellular hemoglobin enhanced the gene expression and protein levels of vascular endothelial growth factor (VEGF) and other hypoxia-inducible factor-related genes in the lung. Extracellular hemoglobin also increased myeloperoxidase activity in the lung. In conclusion, extracellular hemoglobin contributes to the inflammatory response in severe acute pancreatitis through abdominal fat necrosis and inflammation

  10. Isolation and characterization of stromal progenitor cells from ascites of patients with epithelial ovarian adenocarcinoma

    PubMed Central

    2012-01-01

    Background At least one-third of epithelial ovarian cancers are associated with the development of ascites containing heterogeneous cell populations, including tumor cells, inflammatory cells, and stromal elements. The components of ascites and their effects on the tumor cell microenvironment remain poorly understood. This study aimed to isolate and characterize stromal progenitor cells from the ascites of patients with epithelial ovarian adenocarcinoma (EOA). Methods Seventeen ascitic fluid samples and 7 fresh tissue samples were collected from 16 patients with EOA. The ascites samples were then cultured in vitro in varying conditions. Flow cytometry and immunocytochemistry were used to isolate and characterize 2 cell populations with different morphologies (epithelial type and mesenchymal type) deriving from the ascites samples. The in vitro cell culture model was established using conditional culture medium. Results The doubling times of the epithelial type and mesenchymal type cells were 36 h and 48 h, respectively, indicating faster growth of the epithelial type cells compared to the mesenchymal type cells. Cultured in vitro, these ascitic cells displayed the potential for self-renewal and long-term proliferation, and expressed the typical cancer stem/progenitor cell markers CD44high, CD24low, and AC133+. These cells also demonstrated high BMP-2, BMP4, TGF-β, Rex-1, and AC133 early gene expression, and expressed EGFR, integrin α2β1, CD146, and Flt-4, which are highly associated with tumorigenesis and metastasis. The epithelial type cells demonstrated higher cytokeratin 18 and E-cadherin expression than the mesenchymal type cells. The mesenchymal type cells, in contrast, demonstrated higher AC133, CD73, CD105, CD117, EGFR, integrin α2β1, and CD146 surface marker expression than the epithelial type cells. Conclusion The established culture system provides an in vitro model for the selection of drugs that target cancer-associated stromal progenitor cells

    Patients with decompensated cirrhosis often suffer from malnutrition. To enable appropriate nutritional supplementation a correct estimation of resting energy expenditure (REE) is needed. It is, however, unclear whether the volume of ascites should be included or not in the calculations of the REE. In 19 patients with cirrhosis and ascites, measurements of REE by indirect calorimetry were performed before paracentesis, after paracentesis, and four weeks after paracentesis. Moreover, handgrip strength (HGS), dual X-ray absorptiometry (DXA), and biochemistry were assessed. Calculated and measured REE differed more than 10% in 63% of the patients at baseline. By including the weight of ascites in the calculation of REE, the REE was overestimated by 283 (-602-1381) kJ/day (p = 0.69). By subtracting the weight of ascites in the calculation of REE, it was underestimated by -379 (-1915 - 219) kJ/day, (p  = 0.06). Patients in whom measured REE decreased after paracentesis had higher middle arterial pressure (MAP) (p = 0.02) and p-sodium (p = 0.02) at baseline. Low HGS (M: <30 kg; W < 20 kg) was evident in 68% of the patients. T-scores revealed osteopenia and osteoporosis in 58% and 16%, respectively. Reduced vitamin D levels (<50 nmol/l) were found in 68%. The presence of ascites seems to increase REE, why we suggest that when REE is calculated, the weight of ascites should be included. Indirect calorimetry is, however, preferable for REE estimation. More than two-third of patients with ascites suffer from muscle weakness and/or osteopenia.

    (1) Ascites syndrome is a growth-related disorder of broilers that occurs more often in fast-growing birds and at low temperatures. The objective of this study was to estimate genetic and phenotypic correlations among ascites-related traits measured either under cold or under normal temperature conditions, and to estimate genetic correlations between ascites-related traits measured under cold and normal conditions. (2) Several traits related to ascites were measured on more than 4000 chickens under cold conditions and on more than 700 chickens under normal conditions. (3) The heritability estimates for body weight (BW) measured under cold and normal conditions were 0.42 and 0.50, respectively, for haematocrit value 0.46 and 0.17, respectively, and for ratio of right to total ventricular weight 0.45 and 0.12, respectively. (4) The genetic correlation between BW and haematocrit value under cold conditions was -0.23 and between BW and ratio of right to total ventricular weight -0.27. Under normal conditions, however, these genetic correlations were 0.55 and 0.50, respectively. (5) These results demonstrate that the heritability estimates of ascites-related traits as well as genetic correlations between ascites-related traits and BW depend on the temperature conditions under which animals are kept. (6) Strong positive genetic correlations (around 0.8) were observed between total mortality, fluid in the abdomen and ratio of right to total ventricular weight under cold conditions. The genetic correlation between ratio of right to total ventricular weight under cold and normal conditions was 0.91. (7) These results suggest that the ratio of right to total ventricular weight measured under normal temperature conditions might serve as a good indicator trait for ascites.

    Modern broilers have been genetically selected for an increased growth rate and improved feed conversion, but they are also more susceptible to ascites. Ascites occurs when there is an imbalance between available oxygen and the oxygen demand of the broiler. We hypothesized that promoting neonatal gut development with a prebiotic, such as Aspergillus meal (Prebiotic-AM), would enhance gut efficiency, decrease the oxygen demand of the gut, and reduce ascites incidence. In this study, we compared the effect of Prebiotic-AM on ascites incidence and gut development in commercial broilers reared at a local altitude (390 m above sea level) and a simulated high altitude (2,900 m above sea level). Half of the birds received a National Research Council recommended corn-soybean ration, and the other half received the same ration supplemented with 0.2% Prebiotic-AM. These 2 groups were further divided into a local altitude group and a simulated high altitude group for a total of 4 treatment combinations. Tissues were collected on d 1, 3, 7, 14, and 21 from the duodenum and lower ileum and placed in 10% buffered formalin for morphometric analysis. At a simulated high altitude, ascites incidence was 68% for birds fed the Prebiotic-AM supplement compared with 92% ascites incidence in birds given the control feed. The simulated high altitude decreased (P < 0.05) gut development, but prebiotic-treated birds reared in hypoxic conditions had similar gut development to control birds reared at local altitude. These data suggest that a feed ration supplemented with Prebiotic-AM may reduce the effect of hypoxia on broiler gut development and ascites incidence.

    Culture negative neutrocytic ascites is a variant of spontaneous bacterial peritonitis. But there are conflicting reports regarding the mortality associated with culture negativeneutrocytic ascites. Therefore we aim to determine the predictors of mortality associated with culture negativeneutrocytic ascites in a larger sample population. We analysed 170 patients consecutively admitted to intensive care unit with diagnosis of culture negative neutrocytic ascites. The clinical, laboratory parameters, etiology of liver cirrhosis was determined along with the scores like model for end stage liver disease, child turcotte pugh were recorded. The 50 day in-hospital mortality rate in culture negative neutrocytic ascites was 39.41% (n = 67). In univariate analysis, means of parameters like total leucocyte count, urea, bilirubin, alanine transaminase, aspartate transaminase, international normalized ratio, acute kidney injury, septic shock, hepatic encephalopathy and model for end stage liver disease were significantly different among survived and those who died (P value ≤0.05). Cox proportional regression model showed the hazard ratio (HR) of acute kidney injury was 2.212 (95% CI: 1.334-3.667), septic shock (HR = 1.895, 95% CI: 1.081-3.323) and model for end stage liver disease (HR = 1.054, 95% CI: 1.020-1.090). Receiver operating characteristics curve showed aspartate aminotransferase (AST) had highest area under the curve 0.761 (95% CI: 0.625-0.785). Patients with culture negative neutrocytic ascites have a mortality rate comparable to spontaneous bacterial peritonitis. aspartate aminotransferase, alanine aminotransferase (ALT), acute kidney injury (AKI), model for end stage liver disease (MELD) and septic shock are the independent predictors of 50 days in-hospital mortality in culture negative neutrocytic ascites.

    Biological understandings have served as the basis for new computational approaches. A prime example is artificial neural nets which are based on the biological understanding of the trainability of neural synapses. In this paper, we will investigate features of the biological vision system to see if they can also be exploited. These features are 1) the neuron's refractory period - the period of time after the neuron fires before it can fire again and 2) the ocular microtremor which moves the retinal neural array relative to the image. The short term memory due to the refractory period allows the before and after movement views to be compared. This paper will discuss the investigation of the implications of these two features.

  16. Alloimmune refractoriness to platelet transfusions.

    PubMed

    Sandler, S G

    Patients who are transfused on multiple occasions with red cells or platelets may develop platelet-reactive alloantibodies and experience decreased clinical responsiveness to platelet transfusion. This situation, conventionally described as "refractoriness to platelet transfusions," is defined by an unsatisfactory low post-transfusion platelet count increment. If antibodies to HLAs are detected, improved clinical outcomes may result from transfusions of HLA-matched or donor-recipient cross-matched platelets. Because refractoriness is an expected, frequently occurring phenomenon, prevention of HLA alloimmunization is an important management strategy. Prevention strategies include efforts to decrease the number of transfusions, filtration of cellular components to reduce the number of HLA-bearing leukocytes, or pretransfusion ultraviolet B irradiation of cellular components to decrease their immunogenicity. Other investigational approaches include reducing the expression of HLAs on transfused platelets, inducing a transient reticuloendothelial system blockade by infusions of specialized immunoglobulin products, or transfusing semisynthetic platelet substitutes (thromboerythrocytes, thrombospheres) or modified platelets (infusible platelet membranes, lyophilized platelets).

    Transmission electron microscope examination of more than 250 fragments, >1 μm from comet Wild 2 and a giant cluster interplanetary dust particle (GCP) of probable cometary origin has revealed four new calcium-aluminum-rich inclusions (CAIs), an amoeboid olivine aggregate (AOA), and an additional AOA or Al-rich chondrule (ARC) object. All of the CAIs have concentric mineral structures and are composed of spinel + anorthite cores surrounded by Al,Ti clinopyroxenes and are similar to two previous CAIs discovered in Wild 2. All of the cometary refractory objects are of moderate refractory character. The mineral assemblages, textures, and bulk compositions of the comet CAIs are similar to nodules in fine-grained, spinel-rich inclusions (FGIs) found in primitive chondrites and like the nodules may be nebular condensates that were altered via solid-gas reactions in the solar nebula. Oxygen isotopes collected on one Wild 2 CAI also match FGIs. The lack of the most refractory inclusions in the comet samples may reflect the higher abundances of small moderately refractory CAI nodules that were produced in the nebula and the small sample sizes collected. In the comet samples, approximately 2-3% of all fragments larger than 1 μm, by number, are CAIs and nearly 50% of all bulbous Stardust tracks contain at least one CAI. We estimate that 0.5 volume % of Wild 2 material and 1 volume % of GCP is in the form of CAIs. ARCs and AOAs account for <1% of the Wild 2 and GCP grains by number.

    Genetic selection for an ascites-resistant line of broilers is seen as a permanent solution to the ascites problem. Ascites-resistant and ascites-susceptible lines have been developed using sire family selection based on mortality data taken from siblings reared in a hypobaric chamber (simulated 2,900 m above sea level). The relaxed line is representative of the original commercial pureline stock randomly mated with no artificial selection pressure. The objectives of this study were to evaluate the differences between the lines when reared in floor pens and subjected to an ascites-inducing cold stress. Seven hundred eighty three straight run broilers were reared in floor pens at local elevation (390 m above sea level). Feed and water were available ad libitum. Birds were brooded at 32 C during the first week. The second week birds were maintained at 30 degrees C. Cold stress was applied for the remaining 4 wk at 14 degrees C. Mortalities were necropsied daily to determine cause of death. Birds and feed were weighed weekly. At 6 wk, five birds per pen were bled, and half the survivors in each pen (8 to 15 birds) were killed, necropsied, and scored for ascites. Blood gases, clinical chemistries, and blood cell counts were taken. Liver, spleen, split heart, and lung weights were recorded. Body weights were not different among the resistant, susceptible, and relaxed lines (P < 0.05). Feed conversion was better in the resistant line when compared to the susceptible and relaxed lines (P < 0.05). Ascites incidence, as measured by mortality and lesion score at necropsy, was higher in the susceptible and relaxed lines when compared to the resistant line; 18.8, 12.7, and 1.6% respectively (P < 0.001). Susceptible and relaxed lines showed more right ventricular hypertrophy when compared with the resistant line (P < 0.05). The results show that under severe cold stress at local altitude (390 m above sea level), the ascites-resistant line was growing as rapidly as the other

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

    To determine the role of serum procalcitonin levels and ascites/subcutaneous echogenicity ratio (ASER) in predicting ascites infection in hospitalized cirrhotic patients. A total of 50 patients hospitalized because of cirrhosis-related ascites were included in this study. In these patients, 44% of ascites were infected (peritonitis), whereas 56% of ascites were sterile. These two groups were compared in terms of procalcitonin levels and ASER for predicting ascites infection. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of ASER, and the predicting outcome of ASER was compared with procalcitonin levels. The ASER values of the patients with the diagnosis of infected ascites were significantly higher than in those with the diagnosis of sterile ascites (p<0.001). ROC analysis was performed to determine the diagnostic ASER value for infected ascites. An ASER greater than 0.0019 determined peritonitis with 95.5% sensitivity and 100% specificity. A procalcitonin level greater than 0.05 determined peritonitis with 86.4% sensitivity and 75% specificity. Using ROC analysis, an ASER greater than 0.0019 [area under curve (AUC): 0.974, 95% confidence interval (CI) (0.884-0.999, p<0.001)] was a significantly better diagnostic marker than a procalcitonin level >0.5 mg/dL [AUC: 0.860, 95% CI (0.884-0.999, p<0.001) (p<0.045)]. According to our findings, the determination of ASER and serum procalcitonin levels seems to provide satisfactory diagnostic accuracy in differentiating ascites infections in hospitalized cirrhotic patients. ASER values significantly differentiate ascites infections better than procalcitonin levels.

    Carbohydrate antigen 125 (CA125) is a tumor-marker frequently associated with ovarian malignancies; however, benign gynecologic conditions (e.g. ovarian cysts) commonly cause a smaller increase in CA125 levels. This report describes an elderly Japanese woman with high CA125 levels and massive ascites caused by hypothyroidism. A 67-year-old woman presented herself with a weight gain of about 12 kg and abdominal distension. Her serum CA125 level was markedly elevated (822 U/ml) and abdominal CT revealed a right ovarian cyst and massive ascites. Hormonal laboratory data showed severe primary hypothyroidism with a serum TSH of 594 IU/L and a free thyroxin level of 0.05 ng/dl. Ascitic fluid was found to be exudate with a high protein content of 42 g/L. Cytological analysis and FDG-PET showed no evidence of malignancy. The ascites completely disappeared and serum CA125 normalized after adequate hormonal replacement therapy. These data suggest that hypothyroidism should be considered in patients with ascites and elevated serum CA125.

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

    Episodic angio-oedema with eosinophilia (EAE) or Gleich's syndrome is a rare condition characterised by recurrent episodes of oedema and eosinophilia, accompanied by urticaria, fever and weight gain. The presence of ascites has not been reported so far. We report a 21-year-old Caucasian woman who presented with marked ocular oedema and ascites. Laboratory evaluation revealed marked eosinophilia. During the last 3 months, three episodes of facial and neck oedema were reported, which resolved spontaneously over a period of 3-5 days. The diagnosis of EAE was established after exclusion of secondary causes (infections, allergic reactions, collagen diseases, neoplasms) and clonal disorders associated with marked eosinophilia. Low-dose steroids resulted in eosinophil decrease and complete resolution of symptoms, including ascites. This case highlights that ascites can be a very rare manifestation of EAE particularly if other more frequent causes of ascites have been excluded and the clinical and laboratory findings are supportive of EAE. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

  7. Erotic complications.

    Slochower, J

    1999-12-01

    The author argues that erotic transference-countertransference dynamics present particular complexities when they develop between gender constellations other than male analyst and female patient. She addresses the dynamics of a complicated erotic transference in concert with an aversive countertransference response as it evolved between a female analyst and female patient. The intense erotic transference that developed defied classification as either maternallerotic or oedipallerotic, and instead included both features in a rapidly shifting process that was difficult to address analytically. The analyst's confused, often aversive, response to her patient's erotic wishes ultimately revealed a subtle re-enactment involving split-off and erotised experiences of emotional penetration and scrutiny. When these issues were addressed, the erotic transference dissolved, and the analyst's experience of her patient shifted rather dramatically. It is suggested that complex erotic transference sometimes contains within it evidence of previously repressed object experiences that were not primarily sexual in nature.

    Acellular fraction of ascites might play an active role in tumor development. Nevertheless the mechanisms involved in the tumor-modulating properties are still controversial. Here, we demonstrate that malignant ascites from 8 patients with epithelial ovarian cancer did not influence proliferative or invasive properties of ovarian cancer cells, but promoted H2O2-induced apoptosis and increased sensitivity to paclitaxel. Malignant ascites induced BRCA1, Fas and FasL expression and phosphorylation of JNK, but not the activation of caspase pathway. Ascites-induced apoptosis of ovarian cancer cells was strongly inhibited by a JNK inhibitor suggesting a critical role of JNK pathway in ascite-induced apoptosis. The use of siRNA JNK confirmed the importance of JNK in ascites-induced Fas and FasL expression. These results demonstrate that malignant ascites induce apoptosis of ovarian cancer cells and encourage us to think about the clinical management of ovarian cancer patients with malignant ascites.

    Cardiogenic shock is a condition marked by low cardiac output and end-organ hypoperfusion frequently requiring hemodynamic support, and it carries a high mortality. Extracorporeal membrane oxygenation (ECMO) is an effective tool in providing mechanical circulatory support in patients with cardiogenic shock refractory to conventional medical therapies. ECMO can be an essential bridge to recovery, ventricular assist device implantation or transplant. A multidisciplinary team approach is needed in managing such patients and intensive monitoring is required to avoid complications from ECMO. Nevertheless, randomized clinic trials are warranted to prove a survival benefit.

    Next to water, tea is the most ancient and widely consumed beverage in the world. Epidemiological studies have suggested a cancer protective effect, but the results obtained so far are not conclusive. In the current study, mechanisms of the apoptogenic effect of black tea extract were delineated. Black tea administration to Ehrlich's ascites carcinoma (EAC)-bearing Swiss albino mice caused a significant decrease in the tumor cell count in a dose-dependent manner. Flowcytometric analysis showed an increase in the number of cells in the sub-G(0)/G(1) population signifying tumor cell apoptosis by black tea. These results were further confirmed by nuclear staining that demonstrated distinct morphological features of apoptosis. Our data also revealed an increase in the expression of pro-apoptotic protein p53 in EAC. It is known that upon p53 induction, multiple downstream factors contribute to the decision making between growth arrest and apoptosis. Among those, pro-apoptotic gene Bax is up regulated during p53-mediated apoptosis. On the other hand, p53-mediated growth arrest involves p21 as a major effecter. In our system, increase in p53 expression was followed by moderate expression of p21/Waf-1 and high expression of Bax at protein levels. Interestingly, anti-apoptotic protein Bcl-2 was down regulated resulting in decrease in Bcl-2/Bax ratio. All these observations together signify that black tea-induced apoptogenic signals overrode the growth-arresting message of p21, thereby leading the tumor cells towards death.

    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 beta-arabinofuranosyladenine, 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 such as LET or z/sup 2//beta 2. 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.

    Pulmonary hypertension syndrome (PHS), or ascites, is characterized by elevated pulmonary arterial pressure and pulmonary vascular resistance accompanied by right ventricular hypertrophy (RVH) and fluid accumulation in the abdominal cavity. Experimental models are required for triggering PHS to study the pathogenesis of this syndrome and to select resistant genetic lines. Caffeine increases vascular resistance and promotes systemic hypertension in mammals, but a similar effect of caffeine on the pulmonary circulation had not previously been demonstrated. Two experiments were conducted to evaluate the impact of caffeine alone (Exp. 1) or in combination with cold temperature (Exp. 2) on parameters associated with PHS in young broiler chicks. In Exp. 1, 288 chicks were distributed among 24 pens and brooded at standard environmental temperatures, and on d 3 through 42 caffeine was added to the water at doses of 0 (control), 6.25, 12.5, 25, 50, and 100 mg/(kg BW·d). In Exp. 2, 192 chicks were distributed among 16 pens and brooded at cool environmental temperatures, and on d 3 through 42 caffeine was added to the water at doses of 0 (control), 15, 30, and 45 mg/(kg BW·d). In Exp. 1 caffeine administered at or above 12.5 mg/(kg BW·d) induced severe PHS and resulted in acute mortality and RVH ( < 0.05). Hematocrit also slightly increased by caffeine supplementation ( = 0.07). In Exp. 2 caffeine-treated broilers exposed to cold temperatures remarkably exhibited PHS incidences and developed RVH with right ventricular to total ventricular weight ratios of 30% or greater. Moreover, hematocrit significantly increased because of caffeine supplementation in cool ambient temperature ( = 0.002). Our data demonstrate that caffeine induces high incidences of PHS in broilers, which is exacerbated by exposure to low temperatures.

    SEM and X-ray analysis were used to study refractory metal particles in five calcium-aluminum-rich inclusions in the Allende meteorite, and a complex variety of compositions and large departures from equilibrium were found. It is suggested that these particles could have been primordial condensates which were isolated from the nebula and from each other at different times by cocondensing oxides. Selective diffusion and/or oxidation of the more oxidizable metals (Mo, W, Fe, and Ni), phase segregations into different alloy phases (fcc, bcc, hcp, and, possibly, ordered phases), and the formation of metastable condensates could have been involved in the genesis of these materials

  15. Should Barbiturates be Used in Refractory Status Epilepticus?

    PubMed

    Holtkamp, Martin

    2016-02-01

    Status epilepticus (SE) is a frequent neurologic emergency, one third of patients do not respond to treatment with benzodiazepines followed by a second antiepileptic drug. While initial treatment of complex partial SE is accordant to that of generalized convulsive SE, further management of refractory SE depends on the risk for acute complications and long-term clinical consequences. These risks are low in complex partial SE; therefore, in this clinical form anesthetics commonly are not used. Generalized convulsive SE-even in its early course-is a potentially life-threatening condition; therefore, prompt use of anesthetics is urgently required. Drugs of choice are barbiturates, midazolam, and propofol, all of which exhibit specific advantages and disadvantages. Up to now, data from clinical studies do not allow to prefer or to discard one of these anesthetics, therefore also barbiturates still should be used in refractory SE. A widely accepted in-house protocol for the management of initial and refractory SE is highly recommended.

    Patients with sarcoidosis undergo spontaneous remission or may be effectively controlled with glucocorticoids alone in many cases. Progressive and refractory pulmonary sarcoidoisis constitute more than 10% of patients seen at specialized centers. Pulmonary fibrosis and associated complications, such as infections and pulmonary hypertension are leading causes of mortality. No universal definition of refractoriness exists, we therefore propose classifying patients as having refractory disease when the following criteria are fulfilled: (1) progressive disease despite at least 10 mg of prednisolone or equivalent for at least three months and need for additional disease-modifying anti-sarcoid drugs due to lack of efficacy, drug toxicity or intolerability and (2) treatment started for significant impairment of life due to progressive pulmonary symptoms. Both criteria should be fulfilled. Treatment options in addition to or instead of glucocorticoids for these patients include second- (methotrexate, azathioprine, leflunomide) and third-line agents (infliximab, adalimumab). Other immunmodulating agents can be used, but the evidence is very limited. Newer agents with anti-fibrotic properties, such as pirfenidone or nintedanib, might hold promise also for the pulmonary fibrosis seen in sarcoidosis. Treating physicians have to actively look for potentially treatable complications, such as pulmonary hypertension, cardiac disease or infections before patients should be classified as treatment-refractory. Ultimately, lung transplantation has to be considered as treatment option for patients not responding to medical therapy. In this review, we aim to propose a new definition of refractoriness, describe the associated clinical features and suggest the therapeutic approach. PMID:26973429

    2010-04-01

    Refractory coeliac disease (RCD) is defined by persistent or recurrent malabsorptive symptoms and villous atrophy despite strict adherence to a gluten-free diet (GFD) for at least 6-12 months in the absence of other causes of non-responsive treated coeliac disease and overt malignancy. Symptoms are often severe and require additional therapeutic intervention besides a GFD. RCD can be classified as type 1 (normal intraepithelial lymphocyte phenotype), or type 2 (defined by the presence of abnormal (clonal) intraepithelial lymphocyte phenotype). Patients with RCD may never have responded to a GFD or may have relapsed despite adherence and initial response to the GFD. RCD type 1 usually improves after treatment with a combination of aggressive nutritional support, adherence to a GFD, and alternative pharmacological therapies. By contrast, clinical response to alternative therapies in RCD type 2 is less certain and the prognosis is poor. Severe complications such as ulcerative jejunitis and enteropathy-associated T cell lymphoma may occur in a subgroup of patients with RCD. The aims of this article are to (1) review recent advances in the diagnosis and management of patients with RCD, and (2) describe current and novel methods for classification of patients with RCD into categories that are useful to predict outcome and direct treatment.

Symptoms are often severe and require additional therapeutic intervention besides GFD. RCD can be classified as type 1 (normal intraepithelial lymphocyte phenotype), or type 2 (defined by the presence of abnormal [clonal] intraepithelial lymphocyte phenotype). Some patients with RCD may never have responded to a GFD or may have relapsed despite adherence and initial response to the GFD. RCD type 1 usually improves after treatment with a combination of aggressive nutritional support, adherence to GFD, and alternative pharmacologic therapies. By contrast, clinical response to alternative therapies in RCD type 2 is less certain and the prognosis is poor. Severe complications such as ulcerative jejunitis and enteropathy-associated T-cell lymphoma (EATL) may occur in a subgroup of patients with RCD. The aims of this article are (1) to review recent advances in the diagnosis and management of patients with RCD and (2) to describe current and novel methods for classification of patients with RCD into categories that are useful to predict outcome and direct treatment.

    Summary Refractory status epilepticus (RSE) can be defined as status epilepticus that continues despite treatment with benzodiazepines and one antiepileptic drug. RSE should be treated promptly to prevent morbidity and mortality; however, scarce evidence is available to support the choice of specific treatments. Major independent outcome predictors are age (not modifiable) and etiology (that should be actively targeted). Recent recommendations for adults, relying upon limited evidence, suggest that RSE treatment aggressiveness should be tailored to the clinical situation: to minimize ICU-related complications, focal RSE without major consciousness impairment might initially be approached more conservatively; conversely, early induction of pharmacological coma is advisable in generalized-convulsive forms. At this stage, midazolam, propofol or barbiturates represent the most used alternatives. Several other treatments, such as additional anesthetics, other antiepileptic or immunomodulatory compounds, or non-pharmacological approaches (electroconvulsive treatment, hypothermia), have been used in protracted RSE. Treatment lasting weeks or months may sometimes result in a good outcome, as in selected cases after cerebral anoxia and encephalitis. Well-designed prospective studies of this condition are urgently needed. PMID:21939901

    Purpose Currently, only a few reports have recommended surgery as a suitable treatment for blepharoptosis associated with myasthenia gravis. The present study aims to introduce our surgical criteria, surgical options, outcomes, and precautions for medically refractory myasthenic blepharoptosis. Patients and methods Eight patients who failed to respond to at least 2 years of medical treatment and who underwent blepharoptosis surgery, from January 2008 to December 2011, were enrolled in this study. Medical records, photographs, and questionnaire results regarding postoperative status were evaluated. Of the eleven procedures performed, four involved frontal suspension, four involved external levator advancement, one involved nonincisional transconjunctival levator advancement, and two involved subbrow blepharoplasty with orbicularis oculi muscle tucking. The margin reflex distance improved postoperatively in seven patients. Results Seven patients had very minimal scarring, and one had minimal scarring. Five patients showed no eyelid asymmetry, one had subtle asymmetry, and two had obvious asymmetry. Seven patients were very satisfied, and one patient was satisfied with the overall result. Postoperative complications included mild lid lag with incomplete eyelid closure, prolonged scar redness, and worsened heterophoria. No patient experienced postoperative exposure keratitis or recurrent blepharoptosis during the study period. Conclusion Our results indicate that blepharoptosis surgery is effective for patients with myasthenia gravis, especially those with residual blepharoptosis despite multiple sessions of medical treatments. We recommend that neurologists and surgeons collaborate more systematically and discuss comprehensive treatment plans to increase the quality of life for patients with myasthenia gravis.

    During the course of the disease a patient with systemic lupus erythematosus (SLE) may develop inflammation of one or more serous membranes, resulting in pleural, peritoneal, or pericardial effusion. Chylous ascites and chylothorax have rarely been described in patients with SLE. Therefore, in parallel with the analysis of blood samples, detailed analysis of the effusions should be carried out. Supportive measures are often needed to relieve the symptoms of chylothorax or chylous ascites together with the treatment of the primary disease. The available literature had reported just 4 cases of chylous ascites and/or chylothorax in association with SLE, and this patient presented here is one of the rare cases apart from the reported ones.

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

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

    Arterioportal fistulas (APFs) are a group of vascular disorders, in which systemic arteries communicate with the portal circulation, presenting as a congenital syndrome or more commonly acquired from iatrogenic instrumentation or abdominal trauma. We report the case of a 58-year-old man who developed ascites without underlying risk factors for portal hypertension, which was attributed to an APF found on imaging, manifesting 43 years after sustaining a liver laceration. After angiographic embolization of the APF, the patient’s ascites resolved completely. The prolonged latent period between the patient’s abdominal trauma and eventual presentation with ascites highlights the need to consider vascular malformations in the differential diagnosis of unexplained noncirrhotic portal hypertension.

    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

    The objective of this study was to evaluate the gluconeogenic response of in vitro stimulated hepatocytes from control broilers and broilers with clinical manifestations of the ascites syndrome. The basal rate of glucose synthesis from lactate was found to be threefold greater in sick birds than in the control group and stimulation obtained with epinephrine was found to be quantitatively similar in both groups. Under basal conditions, the hepatocytes from the sick broilers exhibited 60% more ammonium than the control birds. In addition, the quantification of thiobarbituric acid reactive substances, as indicators of cellular lipoperoxidation, showed an increase of over 100% in heart and liver of sick broilers fowl. In conclusion, the complex integrated response of gluconeogenesis to epinephrine is maintained in broilers with ascites, although their hepatocytes present changes compatible with those observed in cases of oxidative stress. It is not known whether this stress is a cause or a consequence of the ascites syndrome.

    Refractories play a vital role in slagging gasifier on-line availability and profitability for the next clean power generation system. A recent survey of gasifier users by USDOE indicated that a longer service life of refractories is the highest need among gasifier operators. Currently, Cr2O3 based refractories, the best of commercially available materials for use in slagging gasifiers, last between 3 and 24 months. Researchers at Albany Research Center (ARC) have identified structural spalling, caused by slag penetration, as one of the major failure mechanisms of Cr2O3 refractories through postmortem analysis. New Cr2O3 refractories with phosphate additives have been developed by ARC to decrease slag penetration and thus structural spalling. Laboratory physical property tests indicated that ARC developed refractories are superior to other commercial bricks. One of the ARC developed phosphate containing refractories has been installed in a slagging gasifier. Preliminary results of the performance of this refractory in the gasifier will be reported along with research to develop non-chromia refractories.

  10. Utilization of ascites plasma very low density lipoprotein triglycerides by Ehrlich cells.

    Brenneman, D E; Spector, A A

    1974-07-01

    Much of the lipid present in the ascites plasma in which Ehrlich cells grow is contained in very low density lipoproteins (VLDL). Chemical measurements indicated that triglycerides were taken up by the cells during in vitro incubation with ascites VLDL. When tracer amounts of radioactive triolein were incorporated into the ascites VLDL, the percentage uptakes of glyceryl tri[1-(14)C]oleate and triglycerides measured chemically were similar. The cells also took up [2-(3)H]glyceryl trioleate that was added to VLDL, but the percentage of available (3)H recovered in the cell lipids was 30-40% less than that of (1 4)C from glyceryl tri[1-(1 4)C]oleate. This difference was accounted for by water-soluble (3)H that accumulated in the incubation medium, suggesting that extensive hydrolysis accompanied the uptake of VLDL triglycerides. Radioactive fatty acids derived from the VLDL triglycerides were incorporated into cell phospholipids, glycerides, and free fatty acids, and they also were oxidized to CO(2). Triglyceride utilization increased as the VLDL concentration was raised. These results suggest that one function of the ascites plasma VLDL may be to supply fatty acid to the Ehrlich cells and that the availability of fatty acid to this tumor is determined in part by the ascites plasma VLDL concentration. Although Ehrlich cells incorporate almost no free glycerol into triglycerides, considerable amounts of [2-(3)H]glyceryl trioleate radioactivity were recovered in cell triglycerides. This indicates that at least some VLDL triglycerides were taken up intact. The net uptake of VLDL protein and cholesterol was very small relative to the triglyceride uptake, suggesting that intact triglycerides are transferred from the ascites VLDL to the Ehrlich cells and that hydrolysis occurs after the triglyceride is associated with the cells.

The aim of this study is to evaluate the effects of midodrine on cirrhotic ascites through a meta-analysis and systematic review. We searched PubMed (January 1966-December 2014), EMBASE (January 1966-December 2014), the Cochrane Library (Issue 11, 2014), ScienceDirect (January 1966-December 2014), and the China National Knowledge Infrastructure (January 1979-December 2014) databases using the terms 'midodrine' AND 'cirrhosis' AND 'ascites' AND 'paracentesis' for all relevant randomized controlled trials using midodrine for treatment of cirrhotic ascites. In all, 10 trials with a total of 462 patients were included. As a novel therapy for cirrhotic ascites, midodrine was not found to improve survival [odds ratio (OR) 0.81, 95% confidence interval (CI) 0.23-2.91]; although it might improve response rates (OR 3.36, 95% CI 1.47-7.69) and reduce plasma renin activity (MD -3.10, 95% CI -5.37 to -0.84). When midodrine was used as an alternative to albumin in large-volume paracentesis, the mortality was higher for midodrine than for albumin (OR 10.76, 95% CI 1.35-85.97). However, there was no statistically significant difference in the development of paracentesis-induced circulatory dysfunction between midodrine group and albumin group (OR 1.69, 95% CI 0.43-6.72). Midodrine may have treatment effects on cirrhotic ascites. Better powered and well-designed trials are required to assess the extent of the efficacy of midodrine in specifically targeted patients. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    The leaves of Chenopodium ambrosioides L. [Chenopodiaceae] ('mastruz') have been indicated for the treatment of several diseases, among which the cancer. There are no results focusing the effect of C. ambrosioides treatment on tumor development in vivo. The aim of this study was to investigate the effect of treatment with C. ambrosioides on Ehrlich tumor development. Swiss mice were treated by intraperitoneal route (i.p.) with hydroalcoholic extract from leaves of C. ambrosioides (5 mg/kg) or with PBS (control group) 48 h before or 48 h later the Ehrlich tumor implantation. The tumor cells were implanted on the left footpad (solid tumor) or in the peritoneal cavity (ascitic tumor). To determine the solid tumor growth, footpad was measured each 2 days until the fourteenth day, when the feet were weighed. Ascitic tumor development was evaluated after 8 days of tumor implantation by quantification of the ascitic fluid volume and tumor cell number. The i.p. administration of C. ambrosioides extract before or after the tumor implantation significantly inhibited the solid and ascitic Ehrlich tumor forms. This inhibition was observed in ascitic tumor cell number, in the ascitic volume, in the tumor-bearing foot size and foot weight when compared to control mice. The treatments also increased the survival of tumor-bearing mice. In conclusion, C. ambrosioides has a potent anti-tumoral effect which was evident with a small dose and even when the treatment was given two days after the tumor implantation. This effect is probably related with anti-oxidant properties of C. ambrosioides.

    BACKGROUND AND AIMS. In cirrhotic patients with spontaneous bacterial peritonitis (SBP) higher polymorphonuclear (PMN) count in ascitic fluid have been reported in infections caused by Gram-negative bacilli (GNB) as opposed to Gram-positive cocci (GPC). However, the influence of other associated factors on the PMN count, such as the specific microorganism causing the episode of SBP, has not been well established. METHODS. Retrospective observational study of 194 episodes of positive ascitic and/or blood culture SBP in 159 patients with liver cirrhosis (2001-2009). Parameters associated with PMN count in ascitic fluid at diagnosis were evaluated. RESULTS. The multivariate analysis (model 1) showed that a virulent etiology of the infection [coefficient 3.941 (95% confidence interval (95 CI): 0.421-7.461)] and the model for end-stage liver disease (MELD) score [coefficient 0.196 (95 CI: 0.007-0.384)] were positively associated with the PMN count in ascites, while a nosocomial acquisition was inversely associated [coefficient -3.546 (95 CI: -6.855 - -0.238)]. A nonsignificant trend toward higher PMN count was found in GNB versus GPC, but there were differences between groups of microorganisms: pyogenic streptococci [median (p25-p75): 3211 (1615-8004)], Enterobacteriaceae [2958 (917-7690)], Vibrionaceae [9215 (375-17280)], nonfermenting GNB [1384 (565-3865)], viridans group streptococci [1044 (503-2354)] and enterococci [1050 (476-4655)](p = 0.005). No clear cut-offs of ascitic PMN count predicting a particular etiology could be calculated out of these data. CONCLUSIONS. In cirrhotic patients with SBP, the causing microorganism, the place of acquisition of the infection and the host liver condition were the main factors determining PMN count in ascitic fluid. Third-generation cephalosporin resistance was associated with low PMN count probably because this group included bacteria with inherent low virulence.

    Peritoneal ascites are a distinguishable feature of patients with advanced epithelial ovarian cancer (EOC). The presence of different lymphocyte subsets has been reported in EOC-associated ascites, which also can or not contain malignant cells. The goal of this study was to analyze the functional characteristics of natural killer (NK) cells from EOC-associated ascites in terms of their expression of activating receptors and ascites’ contents of lymphocyte subtypes, cytokine profile and presence of EOC cells. NK cell function was evaluated by the expression of the degranulation marker CD107a in resting and interleukin (IL)-2 stimulated NK cells from ascites and blood. Degranulation of NK cells from EOC cell-free ascites was significantly (p < 0.05) higher than all the other groups, either in their resting state or after IL-2 stimulation, suggesting a previous local stimulation. In contrast, treatment with IL-2 had no effect on NK cells from ascites with EOC cells. The amount of regulatory T cells was significantly higher in ascites with EOC cells compared to EOC cell-free ascites. Ascites with EOC cells also had higher levels of tumor necrosis factor (TNF)-α, suggesting inflammation related to the malignancy. In conclusion, the functional performance of NK cells was distinct between EOC cell-free ascites and ascites with EOC cells. The impairment of NK cell response to IL-2 in ascites with EOC cells was consistent with an immunosuppressive tumor microenvironment. PMID:28513532

    In a previous paper, we reviewed the range of therapies available for the treatment of super-refractory status epilepticus. Here we report a review of the outcome of therapies in refractory and super-refractory status epilepticus. Patients (n = 1168) are reported who had therapy with: thiopental, pentobarbital, midazolam, propofol, ketamine, inhalational anaesthetics (isoflurane, desflurane), antiepileptic drugs (topiramate, lacosamide, pregabalin, levetiracetam), hypothermia, magnesium, pyridoxine, immunotherapy, ketogenic diet, emergency neurosurgery, electroconvulsive therapy, cerebrospinal fluid drainage, vagal nerve stimulation and deep brain stimulation. The outcome parameters reported include control of status epilepticus, relapse on withdrawal, breakthrough seizures and mortality. Where reported (596 cases), the long-term outcome was found to be death (35%), severe neurological deficit (13%), mild neurological deficit (13%), undefined deficit (4%) and recovery to baseline (35%). The quality of reported outcome data is generally poor and the number of cases reported for all non-anaesthetic therapies is low. Outcome assessment is complicated by changes in co-medication, delay in response and publication bias. Given these deficits, only broad recommendations can be made regarding optimal therapy. An approach to therapy, divided into first-line, second-line and third-line therapy, is suggested on the basis of this outcome evaluation. The importance of treatments directed at the cause of the status epilepticus, and of supportive ITU care is also emphasized.
