Frequency Of Spontaneous Bacterial Peritonitis in Chronic Liver Disease

Abstract

Background:  Spontaneous bacterial peritonitis (SBP) is defined as infected ascites in the absence of any recognizable secondary cause of infection.

Objectives:  To find out the percentage of SBP in patients of chronic liver disease with ascites, its clinical and laboratory characteristics.

Place and Duration of Study:  Medical ward II, Jinnah Hospital lahore and duration of study was six months.

Study Design:  Descriptive/ Observational study.

Subjects and Method:  One hundred patients of chronic liver disease with ascities were included in this study.Diagnostic paracentesis was performed immediately upon admission and the bacterial cultures and biochemical analysis was done on sample.

Results:  Ascitic fluid examination was the main basis for establishing the diagnosis of SBP. It was found that SBP was present in 22 patients, out of which 11 were culture positive and 11 were culture negative, 35 patients were HBsAg positive and 65 patients were anti HCV positive. SBP was found in 22 patients out of whom 10 were males and 12 females. Ascites was present in all the patients (100%). Shifting dullness was present in 76 (76%) cases,fluid thrill in 24 cases (24%) and tenderness in 47 patients (47%).

Conclusion:  Frequency of SBP is quite high in patients with chronic liver disease with ascites. SBP should be suspected in all such cases presenting with typical or atypical features.

Key Words:  Spontaneous bacterial Peritonitis (SBP), Ascites, Cirrhosis.
