Spontaneous bacterial peritonitis (SBP) is one of the leading causes of morbidity and mortality in patients with cirrhosis. Spontaneous bacterial peritonitis (SBP) is a common bacterial infection in patients with cirrhosis and ascites, occurring in 10 to 30% of patients, with in-hospital mortality rates ranging from 20 to 30%1. Early diagnosis and a prompt antibiotic therapy have considerably decreased the mortality rate associated with an episode of SBP from 80% to approximately 20- 30% in the last decade. It is secondary to impaired humoral and cellular immune responses that results in indirect intestinal bacterial translocation into the ascitic fluid 2,3. The incidence of spontaneous bacterial peritonitis in hospitalised patients with cirrhosis varies from 7-23% in the West. It is around 33% in Pakistan. Translocation of bacteria (mostly gram negative) from the intestinal lumen due to decreased phagocytic activity of macrophages and increased intestinal permeability in cirrhotic patients is an important step in the development of spontaneous bacterial peritonitis. Spontaneous bacterial peritonitis is also associated with a poor long-term prognosis for patients, as mortality rates can reach 50 to 70% at 1 year
