Renal failure in patients with liver disease is mostly none-organic: prerenal failure or hepatorenal syndrome (HRS). In addition there is organic renal failure, mostly acute tubular necrosis (ATN). In order to avoid functional renal failure cautious diuretic treatment as well as intravenous albumin substitution following paracentesis are pivotal. For prophylaxis of HRS patients with spontaneous bacterial peritonitis shall be given albumin infusions in addition to antibiotic treatment. Patients with HRS type I exhibit a very poor prognosis. Liver transplantation is the only established therapy with long-term success. To bridge the time to transplantation TIPS or terlipressin and albumin can be used.

In 1996, the International Ascites Club defined "refractory ascites" as ascites that cannot be mobilized by medical therapy or that recurs early after initial mobilization despite continued treatment. Of all patients with ascites, 5% to 10% will become refractory to medical therapy. Management of refractory ascites should attempt to control fluid accumulation, reduce the likelihood of developing complications such as spontaneous bacterial peritonitis (SBP) and the hepatorenal syndrome, and improve the patient's nutritional status and overall well-being. Measures to control ascites accumulation include documenting medication and dietary compliance and eliminating potentially nephrotoxic agents that promote sodium retention. Large volume paracentesis is an effective first step in managing these patients and can be performed routinely in an outpatient setting. When more than 5 L of fluid are removed during a paracentesis, intravenous albumin should be infused to reduce the likelihood of the patient developing postparacentesis circulatory dysfunction. Transjugular intrahepatic portosystemic shunt (TIPS) placement effectively eliminates ascites; however, there is no convincing evidence that the shunt improves mortality. Furthermore, it is associated with frequent complications of encephalopathy and shunt malfunction. We feel TIPS should be reserved for patients requiring extremely frequent paracentesis, those who develop significant postparacentesis circulatory dysfunction, or those with hepatic hydrothorax. Patients who have evidence of SBP should be treated with antibiotics and intravenous albumin infusion. Patients who have had a previous episode of SBP or an ascitic fluid protein level of less than 1.0 should receive prophylactic antibiotics. Overall, the prognosis for patients with refractory ascites remains grim, and liver transplantation is the only definitive therapy. Appropriate candidates should be identified promptly and referred for transplant evaluation.

Albumin is the most abundant protein in the circulation. Its main physiologic function is to maintain colloid osmotic pressure. Better understanding of albumin's other physiologic functions has expanded its application beyond maintenance of intravascular volume. In patients with cirrhosis, albumin has been used as an adjunct to diuretics to improve the diuretic response. It has also been used to prevent circulatory dysfunction developing after large-volume paracentesis. Newer indications in cirrhotic patients include preventing hepatorenal syndrome in those with spontaneous bacterial peritonitis, and treating established hepatorenal syndrome in conjunction with vasoconstrictor therapies. The use of albumin for many of these indications is controversial, mostly because of the paucity of well-designed, randomized, controlled trials. The cost of albumin infusions, lack of clear-cut benefits for survival, and fear of transmitting unknown viruses add to the controversy. The latest indication for albumin use in cirrhotic patients is extracorporeal albumin dialysis, which has shown promise for the treatment of hepatic encephalopathy; its role in hepatorenal syndrome or acute on chronic liver failure has not been established. Efforts should be made to define the indications for albumin use, dose of albumin required and predictors of response, so that patients gain the maximum benefit from its administration.

Patients with cirrhosis have altered immune defenses and are considered immunocompromised individuals. Changes in gut motility, mucosal defense and microflora allow for translocation of enteric bacteria into mesenteric lymph nodes and the blood stream. Additionally, the cirrhotic liver is ineffective at clearing bacteria and associated endotoxins from the blood thus allowing for seeding of the sterile peritoneal fluid. Thus, hospitalised cirrhotic patients, particularly those with gastrointestinal hemorrhage, are at high risk of developing bacterial infections, the most common being spontaneous bacterial peritonitis. Given the significant morbidity and mortality associated with spontaneous bacterial peritonitis and the fact that half of the cases are community acquired, all hospitalised cirrhotic patients should have a diagnostic paracentesis to exclude infection. Those admitted with gastrointestinal bleed and a negative paracentesis require short-term prophylaxis with norfloxacin. A third generation cephalosporin is the treatment of choice for spontaneous bacterial peritonitis and, once the acute infection is resolved, secondary prophylaxis with oral norfloxacin is warranted. Patients who develop renal dysfunction at the time of active infection have the highest mortality and require adjunctive albumin therapy. This article reviews the pathogenesis of SBP, the evidence behind the antibiotics used, the rationale for adjunctive albumin therapy in the setting of acute renal failure, and the role of prophylactic antibiotics in specific high-risk populations.

Bacterial infections are well described complications of cirrhosis that greatly increase mortality rates. Two factors play important roles in the development of bacterial infections in these patients: the severity of liver disease and gastrointestinal haemorrhage. The most common infections are spontaneous bacterial peritonitis, urinary tract infections, pneumonia and sepsis. Gram-negative and gram-positive bacteria are equal causative organisms. For primary prophylaxis, short-term antibiotic treatment (oral norfloxacin or ciprofloxacin) is indicated in cirrhotic patients (with or without ascites) admitted with gastrointestinal haemorrhage (variceal or non-variceal). Administration of norfloxacin is advisable for hospitalized patients with low ascitic protein even without gastrointestinal haemorrhage. The first choice in empirical treatment of spontaneous bacterial peritonitis is the iv. III. generation cephalosporin; which can be switched for a targeted antibiotic regime based on the result of the culture. The duration of therapy is 5-8 days. Amoxicillin/clavulanic acid and fluoroquinolones--patients not on prior quinolone prophylaxis--were shown to be as effective and safe as cefotaxime. In patients with evidence of improvement, iv. antibiotics can be switched safely to oral antibiotics after 2 days. In case of renal dysfunction, iv albumin should also be administered. Long-term antibiotic prophylaxis is recommended in patients who have recovered from an episode of spontaneous bacterial peritonitis (secondary prevention). For "selective intestinal decontamination", poorly absorbed oral norfloxacin is the preferred schedule. Oral ciprofloxacin or levofloxacin (added gram positive spectrum) all the more are reasonable alternatives. Trimethoprim/sulfamethoxazole is only for patients who are intolerant to quinolones. Prophylaxis is indefinite until disappearance of ascites, transplant or death. Long-term prophylaxis is currently not recommended for patients without previous spontaneous bacterial peritonitis episode, not even when refractory ascites or low ascites protein content is present.

The purpose of this study was to provide evidence-based approaches to detect ascites, perform paracentesis, order tests, and interpret the results. A Medline search was performed to identify relevant articles. Of 731 identified articles, 50 articles were used. The most sensitive findings for ascites detection are ankle edema (93%), increased abdominal girth (87%), flank dullness (84%), and bulging flanks (81%). Paracentesis is safe, with bleeding rates and leakage of <1%. An ascitic fluid polymorphonuclear cell count >or=250 cells/mm(3) is the most sensitive test (86%-100%) to diagnose spontaneous bacterial peritonitis. The serum-ascites albumin gradient is the most useful test in identifying portal hypertension-related ascites. Large-volume paracentesis is effective in the treatment of refractory ascites. We conclude that paracentesis is a safe and vital procedure in patients with new-onset ascites. Once detected, an algorithmic approach to ordering tests and their interpretation is useful to determine etiology and direct further management.

Hepatorenal syndrome is complication of the advanced cirrhosis characterized by functional renal failure and changes of systemic blood pressure due to increased activity of endogenous vasoactive systems. Functional renal failure is due to severe renal cortical ischemia and reduction of glomerular filtration rate (GFR) developing in the late stages of cirrhosis. The pathogenesis of hepatorenal syndrome is the result of an extreme underfilling of the arterial circulation secondary to arterial vasodilatation located in the splanchnic circulation. Reduced effective arterial blood volume triggers a compensatory response with activation of systemic and renal vasoconstrictor systems. At the same time, the ascites becomes refractory in some patients, as it is no longer responsive to diuretic treatment. These changes result from combination of deteriorating liver function and increasing portal pressure, further splanchnic vasodilatation, increase of circulating vasoconstrictors, and decrease of renal blood flow and GFR. Hepatorenal syndrome can be precipitated by shock, infection, nephrotoxic drugs, bleeding, surgery or large volume paracentesis. Renal failure may be rapidly progressive (type I HRS) or may develop more slowly (type II HRS), which is usually associated with refractory ascites. The diagnosis of HRS is based on established diagnostic criteria aimed at excluding the nonfunctional causes of renal failure. The prognosis of patients with HRS is very poor. Liver transplantation remains the only curative treatment for the time being. Pharmacological therapies based on the use of vasoconstrictor drugs may serve as a bridge to liver transplantation. Prevention of HRS by albumin infusion is recommended in patients with spontaneous bacterial peritonitis and by pentoxifylline in patients with the acute alcoholic hepatitis.

Refractory ascites indicates advanced chronic liver disease and represents a therapeutic challenge. It may be triggered by spontaneous bacterial peritonitis and denotes poor prognosis. While liver transplantation is the ultimate treatment, for the relief of ascites therapeutic paracentesis with iv-administration of albumin and/or transjugular intrahepatic portosystemic shunt (TIPS) are well established. With rapid deterioration of renal function patients can develop hepatorenal syndrome. There is increasing evidence that these patients can be bridged to transplantation with vasopressin analogs (terlipressin) and albumin.

Ascites is the most common manifestation in cirrhotic patients, and is associated with a reduced survival rate. Management of ascites is primarily focused on sodium restriction and diuretic treatment to which most patients respond appropriately. For the small group of patients who do not respond sufficiently, interventions such as large volume paracentesis and transjugular intrahepatic portosystemic shunt placement should be considered. Most important in the management of cirrhotic patients with ascites is prevention of complications. Spontaneous bacterial peritonitis and hepatorenal syndrome are severe complications with a poor prognosis when not detected and treated in an early stage. In all hospitalised patients with ascites, an infection of the ascitic fluid should be ruled out. For those patients at risk of developing spontaneous bacterial peritonitis, in particular patients after a first episode and patients with gastrointestinal bleeding, antibiotic prophylaxis should be given. To prevent the hepatorenal syndrome, substitution with albumin is essential, both in patients who experience an episode of spontaneous bacterial peritonitis and in patients treated with large volume paracentesis. For those patients unresponsive to standard treatment regimens, liver transplantation may be the only suitable treatment option.

Bacterial infections are a serious complication of end-stage liver disease (ESLD) that occurs in 20% to 60% of patients. We retrospectively reviewed medical records of patients with ESLD who were identified by our microbiology laboratory as having Streptococcus salivarius bacteremia. Of 592 patients listed for transplantation between January 1998 and January 2006, 9 (1.5%) had 10 episodes of S salivarius bacteremia. Of 2 patients already receiving quinolone prophylaxis for spontaneous bacterial peritonitis (SBP), 1 later presented with a second episode. The male-to-female ratio was 1:1.2. Medians for age, Model for End-Stage Liver Disease score, and Child-Turcotte-Pugh score were 50 years, 17, and 10, respectively. Presenting symptoms and signs in 10 episodes of infection were ascites (in 8 episodes), elevated temperature (6), abdominal pain (5), and encephalopathy (4). Median laboratory values included: white blood cell count, 15.1 x 10(9)/L; creatinine, 0.9 mg/dL; albumin, 3.1 gm/dL; aspartate aminotransferase, 64 U/L; alanine aminotransferase, 52.5 U/L; ammonia, 67 mug/dL; and prothrombin time, 17.3 seconds. Ascitic fluid in patients with peritonitis showed a median white blood cell count of 466 cells/mm(3) (range, 250-12,822 cells/mm(3)), with 66% polymorphs, protein of 0.9 gm/dL, and albumin of 0.4 gm/dL. S salivarius may cause primary bacteremia and SBP in liver transplantation candidates despite quinolone prophylaxis.
