Lasso Score model. The main score and simplified score model to differentiate SBP/SecP from non-infected ascites in patients with hydropic decompensated liver cirrhosis. The probability of infected ascites increases with every score point. The ideal cut-off values of the main score model and the simplified score are >72 and >23.
| Measurement | Score Points | Simplified Model |
|---|---|---|
| CRP > 4.2 mg/dL | +87 | +26 |
| Previous hydropic decompensation | +60 | +17 |
| White blood cell counts > 11.49 G/L | +52 | +16 |
| Organ failure * | +45 | +14 |
| Fever | +39 | +13 |
| Acute gastrointestinal bleeding | +31 | +8 |
| PPI medication | +26 | +8 |
| Previous SBP | +8 | +5 |
| Charlson Comorbidity Index > 6 | +6 | - |
| No propranolol or carvedilol medication | +1 | +2 |
| MELD-Na score > 24.9 | +1 | - |
| Child-Pugh class C | - | +1 |
* Occurrence of any of the following organ failures: serum creatinine ≥ 2 mg/dL; bilirubin > 12 mg/dL; INR ≥ 2.5; encephalopathy, therapy with vasopressors, mechanic ventilation. Abbreviations: CRP, C-reactive protein; PPI, proton pump inhibitors; SBP, spontaneous bacterial peritonitis; MELD-Na model of end-stage liver disease with serum sodium.
