Overview

Epidemiology and Demographics

Prevalence of SBP[1]

  • The prevalence of SBP in cirrhotic patients with ascites admitted to the hospital ranges from 10%-30%.
  • About 50% of cases are present at the time of hospitalization and 50% develop during the hospitalization.

Incidence of SBP

In hospitalized patients

  • Studies have demonstrated a 12% incidence of spontaneous bacterial peritonitis in patients admitted with decompensated cirrhosis.

In outpatient clinic ED setting

  • 2 studies examining asymptomatic patients presenting for a therapeutic paracentesis showed a combined 2.5% incidence of spontaneous bacterial peritonitis (defined as absolute neutrophil count >250 cells/mm3) in 545 patients.[2][3]

Mortality rate of SBP

  • The in-hospital mortality for SBP ranges from 10%-50% depending on various factors.
  • Mortality is 20% even in treated SBP patients
  • Overall one-year mortality rate after a first episode of SBP is 30%-93% regardless of its recurrence.

Age

  • The maximum incidence of SBP was in age group of 41–50 years and the mean age of presentation was 49 years.[4]

Gender

  • In patients with ascites both sexes are affected equally. Male are more commonly affected with SBP probably due to increased alcohol intake leading to cirrhosis.[4]
