Spontaneous bacterial peritonitis (SBP) is a life-threatening complication in patients with ascites caused by advanced liver disease. While gram negative bacteria, such as Escherichia coli and Klebsiella pneumonia are the common pathogens, Listeria monocytogenes has been recognized as a very rare pathogen. Empirical treatment with third generation cephalosporins does not provide adequate antibiotics coverage against L. monocytogenes. Diagnosis is often delayed as it requires confirmation from ascitic fluid culture. Herein, we describe the first case of SBP caused by L. monocytogenes in a patient with advanced alcoholic liver cirrhosis in Korea. Clinicians should be aware of the atypical pathogens, especially in patients with inadequate response to empirical antibiotics.

OBJECTIVETo evaluate the significance of determining ascitic bacterial 16S rRNA by quantitative PCR combined with microarray (PCR-microarray) in the diagnosis of spontaneous bacterial peritonitis (SBP).
METHODSAscitic bacterial 16SrRNA was determined by real time fluorescent quantitative PCR-microarray in 76 cases of suspected SBP and 6 cases of non-infectious ascites with chronic liver diseases. The results were compared with ascitic bacterial culture simultaneously.
RESULTSOf 76 ascitic samples, 17 were detected bacteria positive by PCR-microarray, including 8 Grams positive(G+) and 9 Grams negative(G-), which was higher than that by bacterial culture which had only 6 ascitic samples detected positive (all G-); the positive rates were 22.4% vs 7.9%, respectively (P < 0.01). The bacterial strains detected by both methods in 6 cases had a consistency with each other. No bacteria were detected in another 6 cases of non-infectious ascites with chronic liver diseases.
CONCLUSIONSDetermination of ascitic bacteria 16S rRNA by PCR-microarray has a higher specificity and sensitivity in the diagnosis of SBP as compared with the bacteria culture. Application of this novel method can not only accelerate SBP diagnosis but also stratify the different pathogens.

OBJECTIVETo evaluate the value of ascitic bacterial 16S rRNA gene determination in the rapid diagnosis of spontaneous bacterial peritonitis (SBP).
METHODS16S rRNA gene from bacterial DNA in ascites was determined by quantitative fluorescent polymerase chain reaction (PCR) in 76 patients with suspected SBP and 6 patients with non-infectious ascites. The results were compared with those obtained from bacterial culture.
RESULTSThe positive rate of SBP was 22.4% among patients detected with ascitic bacterial 16S rRNA gene determination-based quantitative fluorescent PCR, which was significantly higher than that (7.9%) in patients only received bacterial culture (P<0.05). In addition,in 6 patients with non-infectious ascites,both the 16S rRNA gene determination-based quantitative fluorescent PCR and bacterial culture showed negative results.
CONCLUSIONS16S rRNA gene determination-based quantitative fluorescent PCR can be an effective tool for the rapid diagnosis of SBP. It is more sensitive than the bacterial culture.

We describe the first case of primary peritonitis in Korea of a healthy person due to Streptococcus pyogenes. In the absence of comorbid conditions, such as liver cirrhosis, immunosuppression, or nephrotic syndrome, primary peritonitis is uncommon in a young healthy woman. Abdomen computed tomography revealed ascites in the lower abdomen and peritoneal enhancement suggesting peritonitis. In diagnostic laparoscopy, purulent ascites was found in the pelvic cavity but both ovaries and fallopian tubes were intact. There were no intra-abdominal abnormalities such as bowel perforation, appendicitis, or necrosis. The reports of blood culture, ascites culture, and cervical swab culture confirmed S. pyogenes. After use of antibiotics, the patient was cured and discharged without sequelae.

OBJECTIVETo improve the diagnosis and treatment level of spontaneous bacterial peritonitis (SBP) in the patients with advanced liver disease, get better curative effect and prognosis.
METHODSRegistered the body temperature, symptoms and signs in the abdomen, and blood routine test, the polymorphonuclear (PMN) cell count, and ascites culture in the patients with cirrhosis and fulminant hepatitis. These patients were given supporting therapies including use plasma and albumin as well as antibiotics treatment according to drug sensitivity or empiric. Changes of the body temperature, symptoms and signs were used to evaluate the effect of therapy.
RESULTS186 of 275 inward patients with end-stage liver disease during this period were considered as SBP by ascites culture or clinical experience with various degree symptoms and signs such as pain, distention, higher tension and touch pain in the abdomen. Infective rate was 67.6%. Among them 138 patients had abnormal body temperature more than 37.4 degrees C. 106 patients with leukocyte count in the peripheral blood more than 10 x 10(9)/L; 137 patients with PMN more than 80% in differential cell count; 103 patients with PMN more than 250/mm(3) in ascites. Only 29 patients were culture positive. 82 patients were cured, 17 patients with improvement, 18 patients with inefficacy or deterioration. 42 patients died of hepatic-renal failure and 27 patients died because of upper alimentary tract bleeding, respectively.
CONCLUSIONSigns and symptoms of SBP were atypical in the patients with end-stage liver disease. Ascites culture positive rate was not high. Early diagnosis and proper use antibiotics according to culture and empirics were important to increase effect and improve prognosis

OBJECTIVETo investigate the levels of lipopolysaccharide binding protein (LBP) in serum and ascites of cirrhotic patients, and determine their diagnostic value for spontaneous bacterial peritonitis (SBP).
METHODSCirrhotic patients were divided into groups according to diagnosis of SBP, ascites without SBP, no ascites. To explore the significance of LBP in clinically suspect SBP cases, the ascites without SBP group was sub-divided into two groups according to the symptoms of abdominal pain or elevated white blood cell (WBC) count, and abdominal pain combined with elevated WBC count. Two control groups were composed of patients with intraperitoneal pus and a group of healthy, non-cirrhotic individuals. The LBP levels in serum and ascites were determined by enzyme-linked immunosorbent assay (ELISA). The ascites routine, ascites culture and albumin assay were carried out in the Second Affiliated Hospital of Chongqing Medical University. Data between the two groups were compared using the t-test or nonparametric test of independent samples, and the areas under the curve were compared using the Z test. Results The levels of LBP in serum and pus were significantly higher in the intraperitoneal pus group than in the cirrhosis group with ascites (P less than 0.01).
RESULTSThe level of serum LBP was significantly higher in the cirrhosis group with SBP than in the cirrhosis group without SBP but with ascites and the cirrhosis group with no ascites (P less than 0.01). There was no significant difference in the level of ascites LBP in the cirrhosis group with SBP and the cirrhosis group without SBP but with ascites (P more than 0.05). In the clinically suspect cases with SBP, the levels of LBP in serum and ascites were significantly higher than those in the cirrhosis group without SBP but with ascites (228.00 mug/ml vs. 80.95 mug/ml and 22.50 mug/ml vs. 11.45 mug/ml, P less than 0.05). Determination of serum LBP had a higher sensitivity than the determination of ascites LBP or ascites WBC.
CONCLUSIONGram-negative bacteria infection in the intra-abdominal cavity causes serum and body fluid levels of LBP to increase significantly. Patients with cirrhosis complicated with SBP have significantly elevated levels of serum LBP. The serum and ascites LBP levels are significantly elevated in SBP patients with suspected clinical diagnosis. Measurements of both the serum LBP and ascites LBP may have diagnostic value for SBP.

BACKGROUND/AIMS: The aim of this study was to evaluate the peritonitis-causing bacteria detected in peritoneal fluid using a blood culture bottle in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). METHODS: One-hundred and eleven dialysates from 43 patients suspected of peritonitis related to CAPD were retrospectively evaluated between May 2000 and February 2008. In all cases, 5 to 10 mL of dialysate was inoculated into a pair of BacT/Alert blood culture bottles, and 50 mL of centrifuged dialysate was simultaneously inoculated into a solid culture media for conventional culture. The results were compared to those of the conventional culture method. Isolated microorganisms were compared between the two methods. RESULTS: The blood culture method was positive in 78.6% (88 / 112) of dialysate specimens and the conventional culture method in 50% (56 / 112, p < 0.001). CONCLUSIONS: The blood culture method using the BacT/Alert system is useful for culturing dialysates and improves the positive culture rate in patients with suspected peritonitis compared to the conventional culture method.
