Overview
Common risk factors in cirrhotic patients with ascites include: low protein level in ascitic fluid (<1 g/dL), upper GI bleeding, low complement concentration (complement 3) in ascitic fluid, renal failure, elevated serum bilirubin level (>4 mg/dL), use of proton pump inhibitors (PPI) in cirrhotic patients have an increased risk, Child-Pugh stage C, Model For End-Stage Liver Disease (MELD) ≥ 22.
Risk Factors
Risk factors include:[1]
- All cirrhotic patients with ascites
- Severe liver disease (Cirrhosis)[2]
- Low protein level in ascitic fluid [3]
- Upper GI bleeding poses a risk of bacteremia and SBP in a cirrhotic patient with rates of infection ranging from 17 to 21%
- Ischemia- reperfusion of the gut during variceal hemorrhage has also been proposed to interfere with the normal function of the reticuloendothelial system and to increase permeability of the intestinal mucosa
- Survivors of a prior episode of SBP are at an increased risk of recurrence with a one-year probability of almost 70%
- Minimally invasive procedures such as intravenous and urinary bladder catheterization likely predisposes to bacteremia and SBP in the cirrhotics
- Low complement concentration (complement 3) in ascitic fluid [3][2]
- Renal failure
- Urinary tract infections
- Intestinal bacterial overgrowth [4]
- The use of non-selective beta blockers in cirrhotic patients with SBP should be discouraged since it is associated with an increased risk for hemodynamic compromise, prolonged hospitalization, hepatorenal syndrome, and acute kidney injury[5]
Factors contributing to the infection include:
- GI bleeding
- Increased colonization of the small bowel with prominent bacterial translocation
- Decreased opsonic activity in blood and ascitic fluid
- Impaired complement
- Leukocyte dysfunction
- Reduced antibodies
- Increased immunosuppressive cytokines, endotoxin, TNF
