    Abstract:
    In cirrhotic patients, spontaneous bacterial peritonitis is frequent and severe. This study was performed to determine if low protein concentration in ascitic fluid on admission could predict the occurrence of spontaneous bacterial peritonitis during hospitalization. Ninety-two cirrhotic patients with ascites, without spontaneous bacterial peritonitis were studied. Bacteriologic study and cultures of ascitic fluid were performed on admission and repeated every 5 days, and if any suspicion of infection occurred; 11 patients developed spontaneous bacterial peritonitis during hospitalization. Among the 92 patients in the study, protein concentration in ascitic fluid was initially less than 10 g/l in 45 and 10 of these 45 patients (22 p. 100) developed spontaneous bacterial peritonitis during hospitalization; protein concentration in ascitic fluid was initially greater than 10 g/l in 47 patients; only one of these 47 patients (2.1 p. 100) developed spontaneous bacterial peritonitis during hospitalization. This difference (22 p. 100 vs 2.1 p. 100) was significant (p less than 0.01). Ascitic fluid protein concentration (6.9 +/- 2.3 g/l) was significantly lower (p less than 0.01) in the spontaneous bacterial peritonitis group than in patients without peritonitis (13.8 +/- 10.5 g/l). These results suggest that: 1) ascitic fluid protein concentration on admission is lower in patients who will develop spontaneous bacterial peritonitis during hospitalization than in patients without infection and 2) patients with ascitic fluid protein concentration under 10 g/l on admission represent an high risk group for spontaneous bacterial peritonitis.
