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.
Gender
- Male are more commonly affected with SBP probably due to increased alcohol intake leading to cirrhosis.
