Risk factors for spontaneous bacterial peritonitis (SBP) due to extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella species (ESBL-EK)
| Risk factors | SBP due to | OR (95% CI) | |
|---|---|---|---|
| ESBL-EK (n = 26) |
Non-ESBL-EK (n = 78) |

| Hospital stay before onset of SBP | 23.3 ± 24.8 | 1.6 ± 5.0 | - |

| ≥ 2 weeks (n, %) | 13 (50%) | 3 (4%) | 35.11 (4.57 to 269.72) |
| Presence of hepatocellular carcinoma (n, %) | 9 (35%) | 21 (27%) | 1.46 (0.55 to 3.94) |
| Presentation with septic shock (n, %) | 11 (42%) | 22 (28%) | 2.21 (0.78 to 6.31) |

| ICU care (n, %) | 5 (19%) | 7 (9%) | 2.53 (0.70 to 9.12) |
| Previous history of SBP (n, %) | 19 (73%) | 23 (30%) | 12.91 (2.88 to 57.76) |
| Prior use of antibiotics within 30 days† (n, %) | 21 (81%) | 13 (17%) | 15.13 (4.44 to 51.52) |
SD – standard deviation
OR – odds ratio
CI – confidence interval
†All the patients with a history of use of antibiotics had received 3rd generation cephalosporins within 30 days before the onset of SBP.
