Spontaneous bacterial peritonitis is a well-known entity, with a reported incidence of 15-20% in advanced cirrhotic patients. Escherichia coli and Klebsiella pneumoniae are the most common causes of spontaneous bacterial peritonitis; Brucella is extremely rare. We aimed to present one case of such a rare condition in a cirrhotic patient who also had hepatocellular carcinoma. Routine laboratory tests, abdominal ultrasonography and peritoneal fluid examinations were studied in a cirrhotic patient with ascites. Peritoneal fluid white blood cell count was 1300/mm3, with lymphocyte predominance (80%). Peritoneal fluid and blood culture both yielded Brucella melitensis. The patient also had a mass in the right lobe of the liver confirmed as hepatocellular carcinoma by biopsy. Brucella should be suspected as a cause of spontaneous bacterial peritonitis in cirrhotic patients with no response to standard spontaneous bacterial peritonitis treatments and with immunodeficiency such as hepatocellular carcinoma.

Spontaneous bacterial peritonitis is a major cause of mortality after liver cirrhosis. Altered permeability of the mucosa and deficiencies in host immune defenses through bacterial translocation from the intestine due to intestinal bacterial overgrowth have been implicated in the development of this complication. Molecular mechanisms underlying the process are not well known. In order to understand mechanisms involved in translocation of bacteria, this study explored the role of oxidative stress in mediating changes in intestinal mucosal glycosylation and luminal bacterial content during cirrhosis. CCl4-induced cirrhosis in rats led to prolonged oxidative stress in the intestine, accompanied by increased sugar content of both intestinal brush border and surfactant layers. This was accompanied by changes in bacterial flora in the gut, which showed increased hydrophobicity and adherence to the mucosa. Inhibition of xanthine oxidase using sodium tungstate or antioxidant supplementation using vitamin E reversed the oxidative stress, changes in brush border membrane sugar content, and bacterial adherence. In conclusion, oxidative stress in the intestine during cirrhosis alters mucosal glycosylation, accompanied by an increased hydrophobicity of luminal bacteria, enabling increased bacterial adherence onto epithelial cells. This might facilitate translocation across the mucosa, resulting in complications such as spontaneous bacterial peritonitis.

Liver cirrhosis is a frequent phenomenon in chronic liver diseases such as hepatitis B, hepatitis C, alcohol-related liver damage, autoimmune hepatitis and hemochromatosis. Ascites is the most frequent complication of cirrhosis. We discuss pathogenesis, diagnosis and state-of-the-art clinical management of ascites with emphasis on recent promising developments, such as covered transjugular intrahepatic portosystemic shunt (TIPS). Spontaneous bacterial peritonitis occurs in up to 10% of patients with ascites because of bacterial overgrowth with translocation through the increased permeable small intestinal wall and impaired defence mechanisms. The addition of albumin to standard antibiotic therapy may decrease mortality of spontaneous bacterial peritonitis by decreasing the incidence of renal insufficiency. Patients with coexistent marked hyperbilirubinaemia or pre-existent renal impairment could benefit from adjuvant albumin. Probiotics (bacterial food supplements) have been claimed to improve the state of underlying liver disease and may be useful in the primary and secondary prevention of spontaneous bacterial peritonitis.

Spontaneous bacterial peritonitis (SBP) is a bacterial infection of ascitic fluid which arises in the absence of any other intraabdominal infection source. SBP may develop in all cirrhotic patients with ascites. Gram-negative aerobic bacteria and non-enterococcal Streptococcus spp. are the most common organisms isolated from ascites. Diagnosis necessarily relies on paracentesis and requires a high index of suspicion. The incidence of mortality of the first episode varies between 10% and 46%. Early antibiotic treatment is warranted. Renal impairment develops in approximately one-third of patients with spontaneous bacterial peritonitis and is postulated to arise as a result of a further reduction in effective arterial blood volume. Cefotaxime has been the most extensively studied antibiotic for this infection. It is considered to be one of the first choice antibiotics because of low toxicity and excellent efficacy. Although parenteral antibiotics are generally used, studies evaluated the efficacy of several oral antibiotics in patients with relatively good clinical conditions. The reported probability of spontaneous bacterial peritonitis recurrence one year after the first attack averaged 40 to 69%. Selective intestinal decontamination with 400 mg norfloxacin per day decreased the overall probability of recurrence from 68% to 20% in 1 year of follow-up.

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.

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.

Spontaneous bacterial peritonitis is a serious and frequent complication in childhood nephrotic syndrome. However, this type of complication is very rare in adult nephrotic patients. In the review realized only 15 cases are published with this complication, and none of them after the year 2000. Later we expose the case of a male of 25 years old, proceeding of senegal, with spontaneous bacterial peritonitis, acute renal failure and coagulopatia for malnutrition as form of presentation of a nephrotic syndrome flowery. Besides across the contributed case different aspects of the epidemiology and of the managing of these patients are discussed as well as the last publications on the options of treatment of the glomerulopatia responsible of the clinical symptoms.

One of the most common manifestations of the development of portal hypertension in the patient with cirrhosis is the appearance of ascites. Once ascites develops, the prognosis worsens and the patient becomes susceptible to complications such as bacterial peritonitis, hepatic hydrothorax, hyponatremia, and complications of diuretic therapy. As the liver disease progresses, the ascites becomes more difficult to treat and many patients develop renal failure. Most patients can be managed by diuretics which, when used correctly, will control the ascites. Spontaneous bacterial peritonitis can be treated effectively, but portends a worse prognosis. Once the ascites becomes refractory to diuretics, liver transplantation is the best option, although use of transjugular intrahepatic portosystemic shunts will control the ascites in many patients. Lastly, the development of hepatorenal syndrome indicates the patient's liver disease is advanced, and transplantation again is the best option. However, use of vasoconstrictors may improve renal function in some patients, helping in their management while they await a liver transplant.

Spontaneous bacterial peritonitis is a severe and life-threatening complication in patients with ascites caused by advanced liver disease. The organisms most commonly involved are coliform bacteria and third-generation cephalosporins are the empiric antibiotics of choice. This is an uncommon case of spontaneous bacterial peritonitis caused by Listeria monocytogenes in a female patient with liver cirrhosis from autoimmune hepatitis. She did not improve with ceftriaxone and her course was complicated by hepatic encephalopathy, seizures and multi-organ failure. This case emphasizes that a high index of suspicion should be maintained for timely diagnosis and treatment. Listerial peritonitis should be suspected in patients with end-stage liver disease and inadequate response to conventional antibiotics within 48-72 h. Ampicillin/sulbactam should be initiated while awaiting results of ascitic fluid or blood culture.

The cirrhotic patients are at increased risk of infection greater than patients with other chronic diseases, due to differences in inflammatory and immune reactions. In cirrhotic patients with ascites, you must pay close attention to the prevention of complications such as hyponatremia, hepatorenal syndrome and spontaneous bacterial peritonitis SBP.The hospital mortality after an episode of SBP is 12-15% in the elderly, less than 10% in adults. Over 70% of patients with SBP belong to Class C Child-Pugh. Spontaneous bacterial peritonitis, the most common infection in cirrhosis, is characterized by a bacterial infection of ascites in the absence of conditions of intra-abdominal surgical relevance. After having described the pathogenesis, clinical and management of spontaneous bacterial peritonitis in elderly cirrhotic patients with ascites, the Authors stressed the most recent therapeutic measures and, particularly, the effectiveness of antibiotic treatment. An appropriate focus on the occurrence of complications is essential for life and survival of these patients.
