Spontaneous bacterial peritonitis: clinical study, microbiological findings and clinical course.
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).
