In order to identify the predictive factors of hospital mortality in cirrhotics with spontaneous bacterial peritonitis (SBP), we studied 64 patients who fulfilled the accepted diagnostic criteria. All cases were treated with cefotaxime up to 2 days after the infection was considered cured (7.7 +/- 2.9 days). Eleven patients (17%) died while in hospital, six of them before SBP was cured. After uni- and multivariate analyses, only seven routine clinical, biological, and bacteriological variables studied were independently associated with hospital mortality. These were: the presence of upper gastrointestinal bleeding at admission (beta = 2.01), the absence of abdominal pain as presenting symptom (beta = -1.29), the polymorphonuclear count (%) in the ascites (beta = 0.48), prothrombin rate (beta = -0.22), and serum Na (beta = -0.64), creatinine (beta = 0.50), and cholesterol (beta = -0.68). When the equation obtained was computed in a randomly selected sample of the patients studied, it correctly predicted the outcome in 92.3% of the cases. We conclude that short-term outcome of SBP patients depends on the existence of recent gastrointestinal bleeding, the severity of SBP, and the degree of liver and renal failure. The prognostic value of this model needs prospective validation in a new series of patients.

We made a retrospective study of 233 episodes of spontaneous bacterial peritonitis that were treated at our Service between January 1980 and September 1996 in order to analyze the clinical presentation, microbiological data, possible pathogenic factors, treatment, and evolution of this clinical entity. Ascites, abdominal pain, and fever were the most frequent symptoms. Only 3.43% of the episodes developed asymptomatically. Thirty-six episodes resulted in the patient's death (15.45%) and, of all the factors analyzed, only a prothrombin time of < 35%, bilirubin > 8 mg/dl, and serum creatinine > 2.1 mg/dl were statistically correlated with a higher death rate. The culture of the ascitic fluid gave a positive result in 47.6% of the cases, whereas no clinical differences were noticed between these patients and those with negative results. The most frequently isolated microorganisms turned out to be Gram negative (49.54%). A proportion of 71.24% of the episodes were treated with cephotaxime (i.v.), whereas 28.76% were treated with other drugs or pharmacological combinations. The death rate was much lower with cephotaxime (4.81% vs. 41.79%, p < 0.01%).

One hundred and forty-four episodes of spontaneous bacterial peritonitis (SBP) treated in our service between July 1988 and September 1995 were studied retrospectively to assess the clinical presentation, microbiological findings, possible pathogens, treatment and course. Ascites, abdominal pain and fever were the most common symptoms. Only 3.5% of cases were asymptomatic. The outcome was fatal in 12 (8.33%). Among the factors analyzed, only a prothrombin time of less than 35% correlated significantly with a higher mortality rate (60% and 8.33%, respectively; p < 0.01). Ascitic fluid culture was positive in 43.05% of cases; significant differences existed between these patients and those with negative ascitic fluid culture with respect to clinical findings or course. Gram-negative microorganisms were those most frequently isolated (48.38%). Treatment was initiated within 12 hours in 77.7% of the patients, between 12 and 72 hours in 11.8% and later in 10.41%. Intravenous cefotaxime was administered in 86.1% of cases and other drugs or drug combinations in only 13.9%; the mortality rate was much lower with cefotaxime (2.4% vs 45%; p < 0.01).

We describe two patients awaiting orthoptic liver transplantation in whom diagnostic paracentesis for the diagnosis of spontaneous bacterial peritonitis led to major hemorrhage. Accordingly, we advise caution in patients such as ours, particularly if the prothrombin time or partial thromboplastin time is more than twice the control value.

Cirrhosis of the liver results from a variety of mechanisms that cause progressive hepatic injury. It is the sixth leading cause of death in all patients between the ages of 35 and 55. This study attempts to correlate the morbidity and mortality of spontaneous bacterial peritonitis in liver failure patients to numerous etiologic and clinical variables. A retrospective review of 26 patients with spontaneous bacterial peritonitis associated with chronic liver disease was performed in a university hospital. Demographics (age and gender), clinical variables (etiology of liver failure, Child's classification, prior history of ascites, fever, abdominal pain, encephalopathy, and upper gastrointestinal hemorrhage), and laboratory variables (ascitic polymorphonuclearcyte count and cultures, serum albumin, bilirubin, creatinine, and prothrombin time) were studied. All of the patients had Child's C liver disease. Mortality rate was 46 per cent. Alcohol (46%) and hepatitis (30%) were the most common etiologies. Escherichia coli and Klebsiella pneumoniae were the most common culture isolates. All of the infections were monomicrobial. The only significant predictor of mortality (P < 0.05) in this study was the peritoneal fluid polymorphonuclear (PMN) cell count. PMN count >1000 PMN/mm3 was associated with a mortality of 88 per cent. Few patients with spontaneous bacterial peritonitis are ultimately transplanted.

A recent mandate emphasizes severity of liver disease to determine priorities in allocating organs for liver transplantation and necessitates a disease severity index based on generalizable, verifiable, and easily obtained variables. The aim of the study was to examine the generalizability of a model previously created to estimate survival of patients undergoing the transjugular intrahepatic portosystemic shunt (TIPS) procedure in patient groups with a broader range of disease severity and etiology. The Model for End-Stage Liver Disease (MELD) consists of serum bilirubin and creatinine levels, International Normalized Ratio (INR) for prothrombin time, and etiology of liver disease. The model's validity was tested in 4 independent data sets, including (1) patients hospitalized for hepatic decompensation (referred to as "hospitalized" patients), (2) ambulatory patients with noncholestatic cirrhosis, (3) patients with primary biliary cirrhosis (PBC), and (4) unselected patients from the 1980s with cirrhosis (referred to as "historical" patients). In these patients, the model's ability to classify patients according to their risk of death was examined using the concordance (c)-statistic. The MELD scale performed well in predicting death within 3 months with a c-statistic of (1) 0.87 for hospitalized patients, (2) 0.80 for noncholestatic ambulatory patients, (3) 0.87 for PBC patients, and (4) 0.78 for historical cirrhotic patients. Individual complications of portal hypertension had minimal impact on the model's prediction (range of improvement in c-statistic: <.01 for spontaneous bacterial peritonitis and variceal hemorrhage to ascites: 0.01-0.03). The MELD scale is a reliable measure of mortality risk in patients with end-stage liver disease and suitable for use as a disease severity index to determine organ allocation priorities.

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.

Hilar cholangiocarcinomas are often treated with liver resections. Hepatic dysfunction and infection are common postoperative complications. Although secondary bacterial peritonitis due to abdominal abscess or perforation is common, we report herein the first case of spontaneous bacterial peritonitis after hepatic resection. A 61-year-old male patient without underlying liver disease was diagnosed as having a Klatskin tumor, and a right trisectionectomy with caudate lobectomy was performed. From postoperative days 18-28, the patient gained 4.1 kg as ascites developed, and showed evidence of hepatic insufficiency with prolonged prothrombin time and jaundice. Computed tomography, performed at postoperative day 28 when fever had developed, showed only ascites without bowel perforation or abscess. When paracentesis was performed, the serum-ascites albumin gradient was 2.3 g/dL, indicating portal hypertension, and the ascites' polymorphonuclear cell count was 1,156/mm(3). Since the clinical, laboratory, and image findings were compatible with spontaneous bacterial peritonitis, we started empirical antibiotics without additional intervention. Follow-up analysis of the ascites after 48 hours revealed that the polymorphonuclear cell count had decreased markedly to 108/mm(3); the fever and leukocytosis had also improved. After 2 weeks of antibiotic treatment, the patient recovered well, and was discharged without any problem.

Risk stratification for spontaneous bacterial peritonitis (SBP) in patients with cirrhosis and ascites helps guide care. Existing prediction models, such as end-stage liver disease (MELD) score, are accurate but controversial in clinical practice. We developed and validated a practical user-friendly bedside tool for SBP risk stratification of patients with cirrhosis and ascites. Using classification and regression tree (CART) analysis, a model was developed for prediction of SBP in cirrhosis with ascites. The CART model was derived on data collected from 676 patients admitted from January 2007 to December 2009 retrospectively, and then was prospectively tested in another independent 198 inpatients between January 2010 and December 2010. The accuracy of CART model was evaluated using the area under the receiver operating characteristic curve. The performance of the model was further validated by comparing its predictive accuracy with that of the MELD score. Furthermore, the model was used to stratify SBP among patients with MELD scores under 15. CART analysis identified four variables for prediction of SBP: creatinine, total bilirubin, prothrombin time and white blood cell count, and three risk groups: low (2.0%), intermediate (27.5-33.3%) and high (60.6-86.4%) risk. The accuracy of CART model (0.881) exceeded that of MELD (0.791). Subjects in the intermediate risk and high risk groups had 22.21-fold (95% confident interval (CI), 9.98-49.45) and 173.50-fold (95% CI, 77.68-634.33) increased risk of SBP, respectively, comparing with the low risk group. Similar results were found when this risk stratification was applied to the validation cohort. Cirrhotic patients with ascites at low, intermediate, and high risk for SBP can be easily identified using CART model, which provides clinicians with a validated, practical bedside tool for SBP risk stratification.

A combined experience of 37 cases of subacute hepatic failure encountered in five major gastroenterology centres over a period of ten years is discussed. Majority (65%) were males with average age of 38 years. Maximum (54%) were in 5th decade. Jaundice (100%), abdominal distention (38.7%), swelling feet (64%), fever (54%), abdominal pain (54%), exhaustion (78.3%) were the major presenting features. Jaundice and ascites were present in all cases. Pedal oedema (78.3%), hepatomegaly (54%), splenomegaly (32.4%) and encephalopathy (27%) were the other important clinical features. Hypoalbuminemia and prolonged prothrombin time were significant laboratory findings in addition to hyperbilirubinemia and elevated ALT and AST. Hbs Ag was detected in 46%. Major complications encountered were renal failure (48.7%), spontaneous bacterial peritonitis (43.2%), other infections (43.2%), encephalopathy (43.2%) and upper gastrointestinal bleed (22%). 54% died during stay in hospital. To conclude subacute hepatic failure is potentially fatal condition.
