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)

Infection is a common complication in patients who receive continuous ambulatory peritoneal dialysis (CAPD). Fungi causing peritonitis in these patients is less common compared with bacterial peritonitis. Fungal peritonitis accounts for less than 10% of cases in chronic CAPD, which usually follows either bacterial peritonitis or earlier exposure to broad-spectrum antibiotics. Most of these cases are caused by Candida albicans or other Candida species. There are only two case reports of Penicillium species peritonitis in patients with CAPD in the literature. We report the known third case of Penicillium species-related peritonitis in a patient receiving CAPD. The patient's condition improved dramatically after catheter removal.

Intraabdominal infection continues to be one of the major challenges in general surgery. Whilst the term "peritonitis" means an inflammation of the peritoneum regardless of its etiology, intraabdominal infections encompass all forms of bacterial peritonitis, of intraabdominal abscesses and of infections of intraabdominal organs. Several classification systems have been suggested for peritonitis and intraabdominal infections, respectively. However, neither phenomenological classifications nor classification systems with respect to the origin of bacterial contamination have a proven relevance for the clinical course of this disease. Moreover, most of the studies dealing with secondary peritonitis or intraabdominal infections are ill-comparable because of wide variations of inclusion criteria. Thus the true incidence of secondary bacterial peritonitis is difficult to assess. With respect to its etiology perforation of hollow viscus is the leading cause followed by postoperative peritonitis, ischemic damage of bowel wall, infection of intraabdominal organs and translocation in nonbacterial peritonitis. The anatomic origin of bacterial contamination and microbiological findings are no major predictors of outcome. However, the preoperative physiological derangement, the surgical clearance of the infectious focus and the response to treatment are established prognostic factors. The pathogenesis of intraabdominal infections is determined by bacterial factors which influence the transition from contamination to infection. Intraabdominal adjuvants and the local host response are additionally important. Bacterial stimuli lead to an almost uniform activation response which is triggered by reaction of mesothelial cells and interspersed peritoneal macrophages and which also involves plasmatic systems, endothelial cells and extra- and intravascular leukocytes. The local consequences of this activation are the transmigration of granulocytes from peritoneal capillaries to the mesothelial surface and a dilatation of peritoneal blood vessels resulting in enhanced permeability, peritoneal edema and lastly the formation of protein-rich peritoneal exudate.

Although Taiwan is not an area where cholera is endemic, from October 1988 to October 1997 30 episodes of non-O1, non-O139 Vibrio cholerae infection were noted at the National Cheng Kung University Hospital in Taiwan. Infections generally occurred in hot seasons, and two episodes were concomitant with Vibrio vulnificus infection. Three major clinical presentations were found: bacteremia with concurrent spontaneous bacterial peritonitis or invasive soft-tissue infections that occurred solely in cirrhotic patients; self-limited acute febrile gastroenteritis that occurred in patients with no underlying medical disease; and necrotizing fasciitis or cellulitis that often resulted from a wound on extremities. Other manifestations included fatal pneumonitis in a drowned man and acute pyosalpinx. The differential diagnosis of invasive infections in cirrhotic patients should include infections due to non-O1 V. cholerae or V. vulnificus, and a third-generation cephalosporin and a tetracycline analogue or a fluoroquinolone alone is recommended for treatment of severe vibrio infections.

Selective intestinal decontamination with norfloxacin is useful to prevent bacterial infections in several groups of cirrhotic patients at high risk of infection. However, the emergence of infections caused by Escherichia coli resistant to quinolones has recently been observed in cirrhotic patients undergoing prophylactic norfloxacin. Our aim is to determine the characteristics of the infections caused by E. coli resistant to norfloxacin in hospitalized cirrhotic patients. One hundred and six infections caused by E. coli in 99 hospitalized cirrhotic patients were analyzed and distributed into two groups: group I (n = 67), infections caused by E. coli sensitive to norfloxacin, and group II (n = 39), infections caused by E. coli resistant to norfloxacin. The clinical and analytical characteristics at diagnosis of the infection were similar in both groups. Previous prophylaxis with norfloxacin was more frequent in group II (15/67, 22.4% vs. 32/39, 82%, P <.0001), as a result of a higher number of patients submitted to continuous long-term prophylaxis in this group, whereas previous short-term prophylaxis was similar in both groups. Infections were more frequently nosocomial-acquired in group II than in group I (17/67, 25.3% vs. 20/39, 51.2%, P =.01). The type of infections was similar in both groups: urinary tract infections 38 in group I and 24 in group II, spontaneous bacterial peritonitis 8 and 2, spontaneous bacteremia 4 and 4, and bacterascites 1 and 0, respectively (pNS). Mortality during hospitalization was similar in the two groups (4/67, 5.9% vs. 5/39, 12.8%, pNS). None of the E. coli resistant to norfloxacin were also resistant to cefotaxime and only one of them was resistant to amoxicillin-clavulanic acid. Prophylaxis with norfloxacin, usually continuous long-term prophylaxis, favors the development of infections caused by norfloxacin-resistant E. coli. Long-term antibiotic prophylaxis should therefore be restricted to highly selected groups of cirrhotic patients at high-risk of infection. Infections caused by E. coli resistant to norfloxacin show a severity similar to those caused by sensitive E. coli. No significant associated resistance between norfloxacin and the antibiotics most frequently used in the treatment of bacterial infections in cirrhotic patients has been observed.

Forty patients with spontaneous bacterial peritonitis, three of whom had complicating acute hepatitis syndrome, eight late-onset hepatic failure, and 29 with cirrhosis, were treated with ceftriaxone 2 g intravenously once daily for 5 days. Ascitic fluid culture was positive in 28 patients, with Escherichia coli and Klebsiella as common isolates. All the bacteria isolated were sensitive to ceftriaxone except Enterococcus faecalis, which was isolated in a cirrhotic patient. All culture-positive patients sensitive to ceftriaxone showed bacteriological cure and 26 (65%) patients showed cytological cure after 48 hours of treatment. A total of 95% were cured of their infection after 5 days of treatment. Twelve (30%) patients died during hospitalisation after documented cure of their spontaneous bacterial peritonitis (renal failure, gastrointestinal bleed and cerebral oedema were the primary causes of death). Infection-related mortality due to Pseudomonas septicaemia was seen in one cirrhotic patient.

Non-typhoidal Salmonella is a rare cause of spontaneous bacterial peritonitis (SBP). Non-typhoidal Salmonella SBP has been reported in patients with relatively normal ascitic fluid protein levels. Five patients with non-typhoidal Salmonella SBP and a review of the literature are reported. These patients had chronic underlying disorders, such as malignancy, or other conditions causing immunosuppression. In previous reports, an ascitic fluid protein level above 1.5 g/dl was present in six patients, and under 1.5 g/dl in two. In the present report, ascitic fluid protein is above 2.5 g/dl in three patients and under 1.5 g/dl in one. Immunosuppression and the virulence of the organism seem to play a major role in non-typhoidal Salmonella SBP. Physicians should be alert to the possibility of non-typhoidal Salmonella infection in patients with SBP and normal protein levels in ascitic fluid.

Hepatic cirrhosis is the most common cause of ascites. It is caused by liver failure leading to complex interrelated circulatory and renal changes resulting in retention of sodium and water and portal hypertension localising that sodium and water in the peritoneum. Ascites is an important development in cirrhosis as it implies a generally poor long term prognosis. Investigation is important as ascites is not always dueto cirrhosis, may bethe consequence of complications of cirrhosis such as hepatocellular carcinoma, and may be associated with infection which is fatal if untreated. Most patients respond to treatment with sodium restriction and diuretic drugs. This treatment takes time, and increasingly doctors use therapeutic paracentesis with sodium restriction and diuretics to prevent recurrence of ascites. Paracentesis, however, is not without complications, and it is particularly important to give colloid replacement to prevent hypovolaemia which can lead to renal failure. Patients who do not respond to this treatment may be helped by a TIPSS procedure or a peritoneovenous shunt. However, these patients usually have very poor liverfunction and the possibility of fiver transplantation should be considered. Infection is a very serious complication of ascites (spontaneous bacterial peritonitis) and carries a generally poor prognosis.Antibiotic prophylaxis is important to prevent recurrence and liver transpiantation shoulcl be considered.

Infections in patients affected with liver cirrhosis are frequent, recurrent and associated to unfavorable outcome. They are facilitated by acquired and progressive defects on the innate immune and reticuloendothelial system that are aggravated by alcohol consumption. Infections in patients with cirrhosis are typically bacterial or viral in origin and have in most cases a stereotyped clinical presentation, although diagnosis may be difficult in some cases. Pneumonia, urinary tract infection, bacteremia and spontaneous bacterial peritonitis explain more than 90% of the cases. The latter requires a high clinical suspicion and a standardized diagnostic work up. Preventive strategies are important in the management of these patients and include chemoprophylaxis against spontaneous bacterial peritonitis in selected cases, vaccines against pneumococcal and influenza infections, and hepatitis A and B vaccine in susceptible patients. Due to limited seroconversion, active immunization should be applied as earlier as possible, before clinical deterioration ensues.

Haemophilus influenzae rarely causes spontaneous bacterial peritonitis. We describe a typical case of spontaneous bacterial peritonitis in which the causative organism was identified as nontypeable H. influenzae, biotype III. Infection progressed despite the presence of adequate serum bactericidal antibody, probably due to the absence of complement in ascites fluid.
