title: Prevalence of spontaneous bacterial peritonitis.
abstract: To assess the prevalence of spontaneous bacterial peritonitis (SBP), ascitic fluid cell count, and ascitic fluid culture by conventional method and by bedside inoculation in blood culture bottles were performed in 31 consecutive patients of liver cirrhosis. Seven (22.58%) patients had ascitic fluid polymorphonuclear count (PMN) more than 500/mm. Ascitic fluid culture by conventional method was negative in all the patients, while in 4 patients culture was positive by bedside inoculation method. Six of 7 patients with SBP or its variant were in Child class C. Clinical features in these patients were abdominal pain (5 patients), fever (4) and encephalopathy (2); serum bilirubin level was 6.8 +/- 5.5 mg/dl, serum albumin 1.98 +/- 0.2 g/dl, prothrombin index 59.8 +/- 12.2%, ascitic fluid protein 0.78 +/- 0.24 g/dl. Three of 7 patients with SBP or its variant expired during hospital stay; the other 4 patients recovered after appropriate antibiotic therapy. We conclude that SBP is a serious complication in patients of liver cirrhosis with ascites. Ascitic fluid PMN count and bedside inoculation of blood culture bottles with ascitic fluid are sensitive indicators of SBP. Hence they should be performed routinely for early detection of SBP.
