Ascites is a common clinical problem in children with liver disease. The peripheral arterial vasodilation hypothesis is mostly accepted as the pathophysiological basis of ascites. The most important complication is spontaneous ascitic fluid infection in the form of spontaneous bacterial peritonitis (SBP) and its variants. Aerobic gram-negative bacteria, primarily Escherichia coli, are the most common isolates. Diagnostic paracentesis is done in patients with ascites when diagnosed first time and at the beginning of each admission to hospital. Ascitic fluid is evaluated for cell count with differential, albumin level, total protein and culture. Serum-ascites albumin gradient (SAAG) is the best single test for classifying ascites into portal hypertensive (SAAG> 1.1 g/dL) and non-portal hypertensive (SAAG < 1.1 g/dL) causes. In patients with tense ascites LVP should be performed. A neutrophil count of > 250 cells/mm3 is highly suggestive of bacterial peritonitis. Intravenous cefotaxime is the empiric antibiotic of choice. Long-term administration of oral norfloxacin 5-7.5 mg/Kg once a day in cirrhotic patients with ascitic fluid protein content of < 1g/dL or prior episode of SBP is recommended for prevention of SBP. Oral dual diuretic therapy of single morning dose of spironolactone along with furosemide in the ratio of 5:2 is recommended. While obtaining satisfactory diuretic response dual diuretic therapy can be changed over to monotherapy with spironolactone. Patients should be on sodium restricted diet. Management of ascites might ultimately require liver transplantation.

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.

Liver transplantation is the treatment of choice for end-stage liver disease in children, but donor shortage is still a main problem in this age group. The aim of the present study is to evaluate the complications and mortality of liver disease in children waiting for transplantation. We analyzed medical records of 83 children aged <18 yr, who were listed for liver transplantation but the organ was not available for them between 1999 and 2006. The outcome was assessed from their records or follow-up data. Among the children (mean age, 8 +/- 5 yr; 50.5% boys) listed for liver transplantation, but the organ was not available for them, the common causes of cirrhosis were biliary atresia (27.7%) and cryptogenic (24.1%). The mean follow-up duration was 14 +/- 13.4 months (range 0.5-54 months). Sixty-seven (80.7%) patients developed one or more complications while awaiting transplantation. The most common complications were gastrointestinal bleeding (44.6%), spontaneous bacterial peritonitis (36.1%), infectious complications (28.9%), encephalopathy (24.1%), renal (18.1%), and pulmonary problems (10.8%). Fifty-one (61.4%) patients needed hospital admission because of complications and 26 (31.3%) patients died while awaiting transplantation. About two-thirds of children listed for liver transplantation needed hospital admission because of complications and one-third of them died without any liver transplantation. It seems that more split liver transplantation as well as the introduction of a live-related program in our center will provide many benefits to our children.

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.

Three patients with hepatic cirrhosis and ascites, a 65-year-old man, a 17-year-old woman and a 49-year-old man, were admitted to hospital for progressive drowsiness, increased ascites, and melaena, respectively. An elevated number of polymorphonuclear leukocytes was found in the ascites. The three patients became more and more seriously ill. On the basis of the laboratory findings, a diagnosis of 'spontaneous bacterial peritonitis' was made. The patients recovered after administration of antibiotics. The signs and symptoms of spontaneous bacterial peritonitis can range from subtle, renal dysfunction or an altered mental state to the signs ofan acute abdomen. The common signs of infection such as fever and an elevated leukocyte count are present in only 50% of the patients. Gram-negative bacteria are most frequently isolated from cultures of the ascites fluid. The 1-year mortality is still 50-70% and is partly a result of the underlying liver disease. Prophylactic oral administration of a quinolone decreases the risk of spontaneous bacterial peritonitis in patients with gastrointestinal haemorrhage and in patients with a prior episode of spontaneous bacterial peritonitis. Long-term prophylaxis has been associated with the development of infections with quinolone-resistant microorganisms.

Infections in patients with end-stage liver disease (ESLD) are an important cause of morbidity and mortality in these patients. Abnormalities in their natural defense mechanisms, alterations in the enteric flora and the growing utilization of invasive procedures increase the risk of infections in these patients. Common bacterial infections in ESLD patients include spontaneous bacterial peritonitis, urinary tract infections, community-acquired pneumonia, dermatologic infections, and bacteremia. Viral infections such as influenza can have a devastating course in ESLD patients. Hepatitis B and C are now among the most common causes of ESLD. They also present an important therapeutic challenge. As patients with human immunodeficiency virus are surviving longer, ESLD due to hepatitis C is now emerging as a leading cause of morbidity in these patients. Prompt detection of infections, use of appropriate antibiotics for treatment and prophylactic measures such as vaccinations can help improve survival in these patients.

Proton pump inhibitors (PPIs) increase enteric bacterial colonization, overgrowth, and translocation, all effects which might predispose to spontaneous bacterial peritonitis. We investigated whether PPI usage is associated with spontaneous bacterial peritonitis. Our retrospective case-control study included 116 consecutive cirrhotic patients with ascites who underwent diagnostic paracentesis upon hospital admission (2002-2005). Spontaneous bacterial peritonitis was defined as paracentesis yielding >or=250 polymorphonuclear leukocytes/ml. We performed logistic regression to determine the risk of spontaneous bacterial peritonitis by PPI usage. Of the 116 subjects, 32 had spontaneous bacterial peritonitis. Patient characteristics were similar between groups with and without infection, with the exception of the Model for End-Stage Liver Disease score (median: 23 and 18, respectively; P = 0.002). Crude and adjusted odds ratios for the development of spontaneous bacterial peritonitis by exposure to PPIs were 1.22 (95% confidence interval: 0.52-2.87) and 1.05 (0.43-2.57), respectively. In conclusion, we did not find a positive association between PPI use and spontaneous bacterial peritonitis.

We performed a retrospective study to determine the influence of bacteremia on the mortality of patients with spontaneous bacterial peritonitis (SBP), a major complication of liver cirrhosis. Patients with SBP with identified pathogens from ascites and/or blood were analyzed by retrospective review of clinical and laboratory records in a university hospital in Korea for 3 y and classified into the bacteremic and non-bacteremic groups. The underlying liver function was determined by model for end-stage liver disease (MELD) score. Microbiological response rate, ascites polymorphonuclear leukocyte (PML) count reduction rate, and SBP-related mortality were compared between the 2 groups. To identify the independent risk factors of mortality, a multiple logistic regression model was used to control for the confounders. A total of 189 patients was enrolled in the study. Among 189 patients, 110 (58.2%) were bacteremic, and 79 (41.8%) non-bacteremic. Escherichia coli was the most common etiologic organism, followed by Klebsiella pneumoniae. MELD scores, microbiological response rate (82.6% vs 88.6%, p=0.295), and ascites PML count reduction rate (33.2% vs 44.8%, p=0.479) were not different between the bacteremic and non-bacteremic group. However, the SBP-related mortality rate of the bacteremic group was significantly higher than that of the non-bacteremic group (37.3% vs 12.7%, p<0.001). Bacteremia (OR=2.86: 95% CI 1.06-7.74, p=0.038), APACHE II score (OR=1.20: 95% CI 1.10-1.31, p<0.001), MELD score (OR=1.07: 95% CI 1.01-1.31, p=0.016) and microbiological no response (OR=5.51: 95% CI 1.82-16.72, p=0.003) were independent risk factors of SBP-related mortality.

HIV coinfection is associated with faster progression of liver disease resulting from hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Thus, liver complications have become a major cause of illness and death in coinfected patients. Controlling HIV through highly active antiretroviral therapy may slow disease progression to nearly the rate of HIV-negative persons. Several antiretroviral regimens have been associated with drug-induced liver injury, however, which is more common in patients coinfected with hepatitis B or C. After development of cirrhosis and decompensation, survival is shorter in coinfected patients. Diagnosis and management of cirrhosis should be the same for coinfected and monoinfected HBV/HCV patients. The main complications of cirrhosis are ascites, spontaneous bacterial peritonitis, bleeding esophageal varices, hepatic encephalopathy, the hepatorenal syndrome, and hepatocellular carcinoma. Liver transplantation is feasible in patients with HIV infection, and early evaluation for this option is crucial because of the accelerated course of complications in HIV coinfection.

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.
