Spontaneous Bacterial Peritonitis (SBP)

Etiology

  • Typically GNRs (e.g. e coli, kebsiella) or GPCs (e.g. strep) that find their way (via translocation from GI tract, v other mechanisms) into ascites

Risk Factors

  • Ascites, typically caused by advanced liver disease
  • Low ascitic protein (< 1.5 --> less ability to opsonize bacteria) increases risk

Symptoms

  • Confusion
  • Sometimes fever
  • Acute abd pain/discomfort which can be subtle

Physical Exam Findings

  • Confused
  • Sometimes fever
  • Sometimes lower bp
  • Generalized abd tenderness in patient with ascites
