    Abstract:
    BACKGROUND: Spontaneous Bacterial Peritonitis (SBP) is a common and potentially fatal complication of cirrhosis. Multiple variants of this infection have been described during the past decade. Few studies have investigated SBP in Brazil. MATERIAL AND METHOD: In order to investigate prospectively prevalence, predictive factors and prognosis of the episode of SBP, we studied 143 in and outpatients with cirrhosis admitted to HUCFF and HUPE between January, 1995 and January, 1996. All patients were submitted to a questionnaire, physical examination, blood analysis and abdominal paracentesis with ascitic fluid analysis. They were followed for a mean follow-up period of 4 months and survival was determined. RESULTS: The prevalence of SBP was 20%. Culture-positive SBP, Culture-negative Neutrocytic Ascites and Bacterascites were identified in 24%, 66% and 10%, respectively. After uni- and multivariate analysis, only anterior gastrointestinal hemorrhage, serum albumin and ascitic fluid C4 reached statistical significance (p = 0.05) as predictive factors for the development of the SBP. The in-hospital and follow-up mortality rates were 33.3% and 53.8% for the SBP patients and 8.5% and 31.9% for the non-SBP patients, respectively (p = 0.01 and p = 0.04). The cumulative probability of survival in the SBP group was significantly lower than the probability of the non-SBP group (p = 0.05). CONCLUSIONS: We conclude that SBP is a frequent complication, depends of the severity of liver failure and is a marker for poor prognosis in patients with liver cirrhosis.
