Study On Ascitic Fluid Complement3 Level In Cirrhotic Patients With Spontaneous Bacterial Peritonitis And Without Spontaneous Bacterial Peritonitis

Abstract

Ascitic fluid Complement 3 (C3) concentration is the most important factor to offer local defense against infection of ascitic fluid. Hepatic synthesis of Complement 3 and its concentration in ascitic fluid is significantly reduced in patients with advanced cirrhosis. The aim of the study was to assess the level of Complement 3 in ascitic fluid in cirrhotic patients with and without spontaneous bacterial peritonitis (SBP) and to identify the group of cirrhotic ascites at risk of developingA prospective case control study was carried out to compare the level of ascitic fluid Complement 3 concentration in patients with SBP (case-group) and without SBP (control-group). Ascitic fluid Complement 3 level was estimated in 15 patients with SBP (case) and another 15 patients without SBP (control).In the study, ascitic fluid Complement 3 concentration was 7.3+/-4.3 mg/dL in patients with SBP and 16.4+/-11.3 mg/dL in patients who did not develop SBP.Ascitic fluid Complement 3 level is significantly (P=0.009) reduced in cirrhotic patients who develop SBP.
