The clinical value of ascitic fluid culture and leukocyte count studies in alcoholic cirrhosis.

Because of the paucity of studies establishing the accepted leukocyte count is sterile ascites, less than 300 WBC per mm3 with 25% polymorphonuclear (PMN) leukocytes, peritoneal fluid WBC counts and bacterial cultures were studied in 63 consecutive hospitalized patients with alcoholic cirrhosis and ascities. In 58 culture-negative patients the ascitic fluid WBC count range was 28 to 1800 and 50% of counts were greater than 300 WBC per mm3. The percentage of PMN leukocytes ranged from 2 to 98%. Five patients with spontaneous bacterial peritonitis (SBP), proven by positive cultures, had an ascitic WBC count range of 300 to 6320 WBC per mm3 and a PMN leukocyte range of 20 to 76%. Physical findings did not allow clear separation of the two groups. Anaerobic organisms were not found. It is concluded: (1) differentiation of SBP from sterile ascities relies on prompt ascitic fluid bacteriology; (2) the improved survival of 40% of SBP patients in this study may be related to an increased awareness of the entity and early treatment.
