BACKGROUNDS/AIMS: Recently, treatment failure with the third generation of cephalosporin was increasingly noted in patients with spontaneous bacterial peritonitis (SBP). We therefore were to evaluate the pattern of antibiotic resistance and its clinical significance. METHODS: We retrospectively analyzed 580 episodes of SBP occurring between 1995 and 1999. There were 87 episodes of SBP in 1995, 222 in 1998, and 271 in 1999. The pattern of isolated organisms and antibiotic resistance, and prognostic factors for survival, were analyzed. RESULTS: Microorganisms were isolated in 41% of total episodes. The three most frequently isolated organisms were E. coli (48%), K. pneumoniae (15%), and Aeromonas (8%). The percentage of resistant strains to cefotaxime (9%, 14%, 32%) and ciprofloxacin (13%, 21%, 32%) significantly increased. The proportion of E. coli producing extended spectrum beta-lactamase (ESBL) also increased significantly (0%, 16%, 33%). The need of secondary antibiotics such as imipenem due to treatment failure was significantly increased from 0% in 1995 to 33% in 1999. Overall in-hospital mortality, however, was not changed (20%, 20%, 24%, respectively). The factor affecting early mortality was renal failure at diagnosis. Prognostic factors for long-term survival were the presence of associated malignancy and ESBL-producing microorganisms. CONCLUSION: Microorgansims resistant to third generation cephalosporin and quinolone were increasingly isolated over the 5 years in patients with SBP. Measures to prevent in-hospital spread of resistant strains and indiscreet use of antibiotics should therefore be instituted.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) has been known to greatly influence the survival rate of patients with liver cirrhosis. However, the factors that affect the survival rate in patients with SBP need to be clarified. METHODS: This study enrolled 95 liver cirrhosis patients diagnosed with SBP. The laboratory findings of their serum and ascitic fluid were examined and the characteristics of the isolated microorganisms in their peritoneal fluid were analyzed. RESULTS: The proportion of patients with culture-positive SBP was 41.1%, and 47 microorganisms were isolated from the ascitic fluid. The proportions of cultured bacteria that were Gram negative and Gram positive were 57.4% and 40.4%, respectively. The proportions of Escherichia coli, Klebsiella species, and Streptococcus species were 25.5%, 19.1%, and 19.1%, respectively. Enterococcus species represented 12.8% of the microorganisms cultured. The overall survival rates at 6, 12, and 24 months were 44.5%, 37.4%, and 32.2%, respectively. There was no relationship between the bacterial factors and the survival rate in SBP. Multivariate analysis revealed that the presence of hepatocellular carcinoma (HCC; P=0.001), higher serum bilirubin levels (> or =3 mg/dL, P=0.002), a prolonged serum prothrombin time (i.e., international normalized ratio >2.3, P<0.001), renal dysfunction (creatinine >1.3 mg/dL, P<0.001), and lower glucose levels in the ascitic fluid (<50 mg/dL, P<0.001) were independent predictive factors of overall survival rate. CONCLUSIONS: HCC, higher serum bilirubin levels, a prolonged serum prothrombin time, renal dysfunction, and lower ascitic glucose levels are associated with higher mortality rates in cirrhotic patients with SBP.
