We describe a case of spontaneous bacterial peritonitis in a 53 year old man affected by cryptogenic micro-macronodular cirrhosis, portal hypertention, splenomegaly and hypersplenism, who was admitted with hepatic failure and septic shock and successfully treated with antibiotics (combination of clindamycin and netilmycin), surgical abdominal drainage and splenectomy. This case gave reason for a literature review and an update on the therapeutic options in these high risk patients, especially concerning the role of surgery. Spontaneous Bacterial Peritonitis (SBP) is defined as a bacterial infection of ascitic fluid in the absence of any septic focus. It is a typical life-threatening complication of hepatic cirrhosis with ascites. Mortality is very high and ranges from 75% to 97% of patients, due to septic shock and hepatic failure (hepatorenal syndrome, hepatic encephalopathy, gastrointestinal bleeding). Infection with a single organism is found in most cases. Gram negative bacilli are present in about 70% of cases and E. coli (less frequently Klebsiella, Serratia, Pseudomonas) is principally found. Gram positive cocchi comprise an additional 30% of cases. Anaerobic and microaerophilic organisms seem to be rare causes of SBP (2.7-6%); this finding is probably due to the intrinsic bacteriostatic activity of ascites, which contains high oxygen tension (70 mmHg) and is an inhospitable environment for bacteroides and Clostridia. The prevalent isolation of enteric organism suggest that the gut is the most frequent source of infection, even if the pathogenetic mechanism is not yet well known. The right treatment depends on differentiating primary (SBP) from secondary peritonitis.(ABSTRACT TRUNCATED AT 250 WORDS)

The number of patients awaiting hepatic transplantation continues to exceed organ donation. As a result, many liver transplant candidates will develop life-threatening complications of their liver disease and not survive the pretransplant waiting period. Recent studies have demonstrated that hepatic lidocaine metabolism into monoethylglycinexylidide (MEG-X) can predict pretransplant survival. The present study was performed to determine if MEG-X could also predict pretransplant complications and thereby be useful in stratifying persons being evaluated for hepatic transplantation. A total of 57 patients with biopsy-proven cirrhosis underwent MEG-X testing. Of 57 patients, 30 (53%) developed life-threatening complications of their liver disease--i.e., variceal bleeding, grade II hepatic encephalopathy or worse, and spontaneous bacterial peritonitis. MEG-X values were greater in persons without complications of liver disease than in persons with complications (25.7 +/- 2.9 versus 14.7 +/- 1.4 ng/ml, respectively). No patients with MEG-X greater than 30 ng/ml developed a major complication. No significant difference in any of the standard liver function tests existed between persons who developed complications and patients who did not. In this group of 57 patients, 4 (7%) died from complications of cirrhosis. Mean MEG-X for patients who died (5.5 +/- 1.6 ng/ml) was significantly less (P < 0.05) than observed for other patient groups. All patients who died had MEG-X values below 10 ng/ml. This suggests that MEG-X testing could be an extremely useful test in the evaluation of patients for hepatic transplantation by identifying persons at increased risk for developing complications of chronic liver disease.

This report summarizes a recent meeting cosponsored by the American Society of Transplant Physicians and the American Association for the Study of Liver Diseases to formulate minimal criteria by which patients with severe liver disease will be placed on the waiting list for liver transplantation. The participants agreed that only patients in immediate need of liver transplantation should be placed on the waiting list. Patients should not be placed in anticipation of some future need for such therapy. It was agreed that minimal criteria could assist but not replace the clinical judgment of the transplant professionals at individual centers. The criteria will be summarized below for adult patients with acute or chronic liver disease. The most important non-disease-specific criterion for placement on the transplant waiting list was an estimated 90% chance of surviving 1 year. This translated into a Child-Pugh score of > or = 7 for patients with cirrhosis which places the patient in Child-Pugh class B or C. Cirrhotic patients who have experienced gastrointestinal bleeding caused by portal hypertension or a single episode of spontaneous bacterial peritonitis would meet the minimal criteria irrespective of their Child-Pugh score. There were disease-specific criteria also. These include a sole minimal criterion for patients with fulminant hepatic failure regardless of etiology of the onset of stage 2 hepatic encephalopathy. A requirement for 6 months abstinence from alcohol before placement on the transplant waiting list was considered appropriate for most patients with alcoholic liver disease. Exceptional cases could get access to the waiting list through a regional review process. Chronic cholestatic diseases present difficulties because of a different natural history than that of chronic hepatocellular diseases. The use of specific risk scores for primary biliary cirrhosis and primary sclerosing cholangitis will likely replace Childs-Pugh classification as the scoring systems become refined. Minimal criteria for any patient with a primary hepatocellular cancer would admit any patient with a tumor confined to the liver irrespective of size or number of tumors, after careful investigation had failed to show spread to lymph nodes, the portal vein, or distant organs. Unusual or rare indications for liver transplantation, including Budd-Chiari syndrome, Wilson's disease, and other hereditary disorders, were also discussed. Finally, it was agreed that there should be no absolute contraindications to placement of patients on the liver transplant waiting list. These criteria should be open to regular review to accommodate advances in the field.

Most bacterial infections in cirrhotic patients are hospital-acquired. Urinary tract infections, spontaneous bacterial peritonitis (SBP), respiratory tract infections, and bacteremia are the most frequent bacterial infectious complications seen in cirrhotic patients. SBP is the most characteristic infectious complication of cirrhotic patients, and it is defined as the infection of a previously sterile ascitic fluid, with no apparent intra-abdominal source of infection. The incidence of SBP in cirrhotic patients admitted to hospital with ascites has been estimated to range between 7 and 23%. The diagnosis is established on the basis of clinical signs and symptoms and/or a polymorphonuclear cell count in ascitic fluid higher than 250/mm3. This diagnosis is confirmed by a positive culture in approximately 70% of the cases. The remaining 30% are considered culture-negative SBP but are empirically treated with antibiotics because severe peritonitis and death may follow if these patients are not treated. Early diagnosis, the routine use of diagnostic paracentesis in patients admitted to hospital with ascites, and, especially, the use of adequate antibiotics are very important tools in the treatment of SBP. Third-generation cephalosporins are the first-choice antibiotic treatment in SBP, although selected patients with SBP, those with normal renal function and without hepatic encephalopathy, shock, or gastrointestinal bleeding, may be treated with oral quinolones. Selective intestinal decontamination with norfloxacin is safe and useful in the primary and secondary prophylaxis of SBP, although the incidence of quinolone-resistant organisms is increasing and this may be a problem in the future.

Hepatic hydrothorax is the accumulation of ascitic fluid in the pleural space and requires the same treatment as ascites: salt restriction, diuretics, and paracentesis. Refractory hydrothorax appears when there is no response to those measures and its management is not well established. Videothoracoscopy is a promising therapy that permits the detection and closure of diaphragmatic defects, and when used with pleurodesis resulted in long-lasting control of hydrothorax in six of eight patients without appreciable morbidity. The transjugular intrahepatic portosystemic shunt is an effective therapy in more than 75% of refractory hydrothorax cases. Hepatic encephalopathy and worsening of liver function in some patients are the main adverse effects. Spontaneous bacterial empyema, the infection of a hydrothorax, was reported in 13% of 120 cirrhotic patients with hydrothorax. Forty percent of the episodes of spontaneous bacterial empyema were not associated with spontaneous bacterial peritonitis. The sensibility of pleural fluid culture improves inoculating pleural fluid into a blood culture bottle at the bedside. Patients with refractory hydrothorax or those having an episode of spontaneous bacterial empyema should be considered candidates for liver transplantation.

Chronic liver diseases are potentially evolving clinical situations which, independently by the etiology, could proceed towards progressive liver structural and functional impairments. The only efficient treatment is orthotopic liver transplantation. Chronic liver diseases, and up to 40% of liver cirrhosis, are initially asymptomatic, but cirrhosis is the most frequent cause of death among non-neoplastic digestive diseases. Important elements complicating a decompensated liver cirrhosis are ascites, hepatic encephalopathy, digestive bleeding and jaundice. Acute liver failure (ALF) is the expression of a clinical state, that is common to many conditions sharing severe liver structural and functional impairments. In patients affected by decompensated liver cirrhosis, ALF could be triggered by several factors, while the death is caused by bleeding episodes, hepato-renal syndrome, spontaneous bacterial peritonitis or hepatocarcinoma. In patients affected by chronic liver diseases, the diagnosis of ALF is based on progressively increasing jaundice, encephalopathy and coagulopathy. Recent clinical trials have evaluated the efficacy of extrahepatic liver support systems, either artificial or bio-artificial, in treating episodes of ALF in chronic liver patients. The preliminary results indicate a potential use of such systems in blood detoxification, but they also showed limits in increasing patient survival.

Childhood liver disorders have, in general, mode of presentations which are distinct from that in adult population. It is due to varying etiology and natural history of the liver diseases in childhood. Chronic hepatitis B and C can be managed with alpha interferon. Remission rates in children have been reported to be between 20-58%. Recently available lamuvidine has also been used in combination with interferon therapy. Oral chelation therapy and liver transplantation have radically affected the outcome of patients with Wilson's disease. Corticosteroids and immunosuppressive therapy are effective in reducing both morbidity and mortality due to auto-immune hepatitis. Offending carbohydrates are eliminated from the diet of patients with galactosemia and hereditary fructose intolerance. The most important and often neglected component of management of chronic liver diseases in childhood are nutritional management and prompt interventions for ascites, spontaneous bacterial peritonitis, portal hypertension and hepatic encephalopathy. With definitive etiological and histological assessment and institution of specific as well as supportive therapy, children with chronic liver disease can have a prolonged survival with improved quality of life. Several of them can potentially receive the liver transplant as and when it becomes available.

Chronic liver diseases often lead to cirrhosis of that organ. As this progresses, hepatic function decreases, and the risk of life-threatening complications increases. Common complications are variceal bleeding, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, hepatorenal syndrome and hepatocellular carcinoma. The only therapeutic option that offers a chance of a cure is transplantation which, however, owing to strict selection criteria and the limited number of donor organs, can be applied only in a minority of patients. For most of the cases, the therapeutic strategy comprises treatment of the underlying disease, prevention and symptomatic treatment of typical complications.

Several age-related changes occur in the structure and functions of the liver. The volume of the liver decreases, despite an increase in the size of hepatocytes, suggesting loss of liver cells. There are decreases in hepatic blood flow, the synthesis of urea and cholesterol, and the metabolism of drugs. Moreover, the regenerative capacity of liver becomes less efficient. Certain caveats are important when treating older patients with liver disease. Strict dietary restrictions, such as a low protein diet, should be avoided in the elderly (unless the patient is encephalopathic) because these patients are often undernourished to start with. Similarly, strict salt restriction should be enforced with caution, since it makes food less palatable and may take away what little desire such patients have to eat. Diuretic doses should be adjusted carefully because of greater risks of azotaemia and electrolyte disturbances in the elderly. Extra vigilance should be exercised in the early detection of infections that are more likely to occur in patients with cirrhosis. For example, spontaneous bacterial peritonitis can be missed in the elderly because of poor systemic (fever, abdominal tenderness) and laboratory responses (leucocytosis). In patients presenting with acute variceal bleeding, it is better to err on the side of underhydration than overhydration because of the risk of congestive heart failure. Vasopressin should be avoided in the elderly, since this drug has a high probability of precipitating an ischaemic event. Older patients do not tolerate beta-blockers as well as younger individuals and may require other treatment strategies for the prevention of variceal rebleeding episodes. Hepatic encephalopathy, especially the milder form, needs careful assessment because it can be easily confused with senile dementia syndromes. Cirrhosis is a premalignant condition and patients are at increased risk of developing hepatocellular carcinoma (HCC), a tumour seen predominantly in the elderly. All patients with cirrhosis should be maintained on a lifelong screening programme consisting of a 6-monthly assessment of alpha-fetoprotein and an imaging study, since early detection provides the only hope for cure of HCC. The only definitive treatment of cirrhosis is liver transplantation. Advanced age is not a contraindication to transplantation, and survival in older patients (aged >60 years) is comparable to that in younger individuals.

Liver cirrhosis is the end-stage of chronic liver disease with a prevalence of 0.5-0.8 percent in the German population. The main causes are chronic viral hepatitis B and C and alcohol abuse. Liver cirrhosis is often oligosymptomatic and frequently only diagnosed when complications occur (laboratory tests, ultrasound, computertomography or nuclear resonance imaging and histology). Complications include portal hypertension, gastrointestinal bleeding, ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, hepatopulmonary syndrome, hepatic encephalopathy and hepatocellular carcinoma. Therapeutic management should mainly focus on the treatment of the underlying chronic liver disease in a precirrhotic stage. In the case of cirrhosis, prevention and treatment of complications are clinically most important.
