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.

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.

PURPOSE: Spontaneous bacterial peritonitis (SBP) frequently develops in patients with liver cirrhosis; however, there is little data to suggest whether the acquisition site of infection influences the prognosis. This study compared the bacteriology, clinical characteristics and treatment outcomes of community-acquired SBP (CA-SBP) and nosocomial SBP (N-SBP). MATERIALS AND METHODS: The medical records of 130 patients with hepatitis B virus (HBV)-related liver cirrhosis, who had experienced a first episode of SBP between January 1999 and December 2008, were reviewed. RESULTS: The study population included 111 (85.4%) patients with CA-SBP and 19 (14.6%) patients with N-SBP. Baseline and microbiological characteristics as well as clinical course, including in-hospital mortality, did not differ between patients with CA-SBP and those with N-SBP (all p>0.05). The median survival time was 6.5 months, and 117 (90.0%) patients died during the follow-up period. Patients with CA-SBP and N-SBP survived for median periods of 6.6 and 6.2 months, respectively, without significant difference (p=0.569). Time to recurrence did not differ between patients with CA-SBP and N-SBP (4.7 vs. 3.6 months, p=0.925). CONCLUSION: The acquisition site of infection did not affect clinical outcomes for patients with HBV-related liver cirrhosis who had experienced their first episode of SBP. Third-generation cephalosporins may be effective in empirically treating these patients, regardless of the acquisition site of the infection.

BACKGROUND: This study was conducted to evaluate the risk factors for infection and clinical outcomes of bacteremic spontaneous bacterial peritonitis (SBP) due to ESBL-producing E. coli and K. pneumoniae, in patients with advanced liver cirrhosis. METHODS: The ESBL production was determined by NCCLS guidelines and/or double-disk synergy tests, on stored E. coli and K. pneumoniae blood isolates collected between 1998 and 2002. Of the patients with advanced liver cirrhosis, 15 case patients, with SBP due to ESBL-producers, were compared with 30 matched controls, with SBP due to non-ESBL-producers. RESULTS: There were no significant differences in age, sex, Child-Pugh scores, or APACHE II scores between the two groups. Significant factors associated with infection by ESBL-producing organisms, according to univariate analysis, were: ICU care, indwelling urinary catheter, central venous catheterization, an invasive procedure within the previous 72 hours, and prior use of antibiotics within the previous 30 days. When assessing the clinical response at 72 hours after the initial antimicrobial therapy, the treatment failure rate was significantly higher in the ESBL group (73.3% vs. 16.7%, p< 0.001). Also, overall 30-day mortality rates were 60% (9/15) in the ESBL groups and 23.3% (7/30) in the control group (p=0.015). CONCLUSION: Among patients with advanced liver cirrhosis, bacteremic SBP due to ESBL-producing E. coli and K. pneumoniae was associated with adverse outcomes, and significantly higher mortality.

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 etiology and management of tertiary peritonitis in the patients with intestinal fistula.

METHODSOne hundred and fifty-three cases of intestinal fistula complicated with tertiary peritonitis were reviewed. The microbiological characteristics, treatment Methods and outcomes were analyzed.

RESULTSThere were 114 males and 39 females with a mean age of (42+/- 19) years. The main causes of intestinal fistula included gastrointestinal surgery (40.5%), trauma (31.4%) and severe pancreatitis (14.4%), etc. The most common cultured bacteria of 157 specimens from 79 patients with tertiary peritonitis were Escherichia coli (24.2%), Pseudomonas aeruginosa (12.1%), Staphylococcus aureus (10.8%), Enterobacter cloacae (10.2%), Klebsiella pneumoniae (8.3%). Debridement of the necrotic tissues, drainage of the abscess, continuous rinsing plus negative pressure drainage and antibiotics treatment were performed in 52 cases. Nineteen patients only changed from simple tube drainage to continuous rinsing plus negative pressure drainage. Twenty- eight patients changed to continuous rinsing plus negative pressure drainage and received antibiotics as well. Thirty- six patients received antibiotics and ecoimmune nutrition, while 18 patients only received ecoimmun nutrition.

CONCLUSIONSIntestinal fistula complicated with tertiary peritonitis was mainly caused by residual infectious focus and inappropriate drainage. The rational treatments include reoperation for debridement of the necrotic and infectious tissues, changing drainage to continuous rinsing plus negative pressure drainage, appropriate usage of antibiotics, and ecoimmune nutrition.

The presence of hyl gene in 364 PFGE clones of Enterococcus faecium was detected by colony hybridization under conditions of high stringency. The isogenic hyl-deficient mutant (* hyl) was constructed with suicide pTX4577 and screened by allelic replacement. Moreover, an in vitro study was made on the effect of hyl gene detection on the growth ability of hylgene detection on the mutant, and an in vivo study was made on the decrease of virulence in the mouse peritonitis model. The results showed, in the clinical isolates, the positive percentage of hyl gene was 32.8%, which was significantly higher than that (5.3%) in the non-clinical isolates. The * hyl was selected by kanamycin and identified by PCR, pulsed field gel electrophoresis (PFGE) and Southern blot. The experimental evidence indicated that the growth ability of * hyl was remarkably reduced in comparison with that of the wild-type strain. The percentage survival of mice in TX2466 groups was 0, while that of * hyl groups was 50% at the same inoculum in mouse peritonitis. The differences were significant. These data suggest that hyl gene in specific E. faecium strains may be enriched in determinants that make them more likely to cause clinical infections. Being important in the pathogenesis, hyl gene is probably a major virulence factor of Enterococcus faecium.
