Overview
Common risk factors for peritonitis in the development of peritonitis include liver disease, dialysis, and abdominal trauma.
Risk Factors
Biochemical risk factors
Well-established risk factors for developing an initial episode of SBP are :
- Low ascitic fluid protein level (<1 g/dL)
- Elevated serum bilirubin level (>4 mg/dL)
- Advanced Cirrhosis
- Low levels of 25-hydroxy vitamin D
- Serum albumin level <2.85 g/dL
Clinical risk factors
- Patients with Vatical hemorrhage and GI bleeding associated with Cirrhosis are more prone to develop SBP irrespective of the presence of ascites.
Genetic risk factors
- The Toll-like receptor 2 (TLR2) proteins[1] variants of the NOD2 (nucleotide-binding oligomerisation domain containing gene and Farnesoid X were known to cause SBP.
Pharmacological risk factors
- Proton pump inhibitors (PPI) has been associated with a three-fold increase in the risk and identified as an independent risk factor for SBP in patients with advanced cirrhosis.
- Beta-adrenergic antagonists namely nonselective beta-blocker (NSBB) therapy was found to be protective for SBP.
Risk factors for development of spontaneous bacterial peritonitis and subsequent mortality in cirrhotic patients with ascites.[2]
- Low serum sodium levels
- Child-Pugh stage C
- Elevated ascites PMN counts (≥100 cells/μl)
- MELD≥22
- Elevated CRP levels
Common risk factors for peritonitis are described as follows:[3]
