Overview
Spontaneous bacterial peritonitis is one variant of ascitic fluid infections.[1] Classification of ascitic fluid infections is based on neutrophil count and culture report.[2][3] Asymptomatic bacterascites is usually the transient residence of bacteria in ascitic fluid without clinical features of peritonitis or increased ascitic fluid polymorphonuclear cells.[4] SBP is also classified based on the routes of infection and the clinical setting as follows health care-associated, nosocomial, community acquired, multi-drug resistant and recurrent.
Classification
- Spontaneous bacterial peritonitis is one of the variants of ascitic fluid infections.[1]
- Classification of ascitic fluid infections is based on neutrophil count and culture report.[2][3]
- Asymptomatic bacterascites is usually the transient residence of bacteria in ascitic fluid without clinical features of peritonitis or increased ascitic fluid polymorphonuclear cells.[4]
Type of Infection | Bacterial Culture Report | Ascitic fluid analysis Neutrophil Count (cells/mm3) | Clinical pearls | |
---|---|---|---|---|
Spontaneous bacterial peritonitis[5] | Positive usually for one organism | ≥250 | Patients with cirrhosis and ascites in the presence or absence of symptoms and signs | |
Culture negative neutrocytic ascites (CNNA)[6][7] | Negative | ≥250 | Poor culture technique and prior antibiotics or low opsonic activity in ascitic fluid. Commonly encountered phenotype and requires antibiotic therapy. | |
Monomicrobial bacterascites[8] | Positive for one organism | <250 | Ascitic fluid infection which may resolve spontaneously or progress to SBP. Mortality is similar to SBP and should be treated as SBP. | |
Secondary bacterial peritonitis | Positive for many microbes | ≥250 | Intraperitoneal source of infection e.g. diverticulitis | |
Polymicrobial bacterascites[9] | Positive for many microbes | <250 | Usually due to bowel perforation by the paracentesis needle and reflects growth of gut flora before the ascitic fluid can mount a neutrocytic response. |
Classification Based on Clinical Setting
Based on the route of infection SBP is classified as follows:[2][10]
Clinical setting associated with SBP | Criteria |
---|---|
Health care-associated SBP (HCA) |
|
Nosocomial SBP |
|
Community acquired SBP (CA) |
|
Multi-drug resistant SBP |
|
Recurrent SBP |
