6%) as Child-Pugh B and only one (2.4%) patient was classified as Child-Pugh A. Three patients (7.1%) were previously diagnosed with SBP, but only one of them (2.4%) was on antibiotic prophylaxis at admission. Seventeen patients (40.5%) did EPZ-6438 chemical structure not have esophageal varices, and 25 (59.5%) had varices (8 [19%] with hemorrhage and 17 [40.5%] without). At hospital admission 12 patients (28.6%) were on proton pump inhibitors, 25 (59.5%) had total serum bilirubin ≥2.5 mg/dL, 21 (50%) had plasma creatinine ≥1.2 mg/dL and 13 (31%) had plasma sodium ≤130 mEq/L (see Table 2). Total serum bilirubin, plasma creatinine, plasma sodium and the presence of esophageal varices did not show a statistically significant association with a higher
mortality Seliciclib risk. Regarding the first paracentesis done during hospitalization, 71.4% (n = 30) of the ascitic fluids analyzed were culture-negative and 4.8% (n = 2), despite having cytochemical SBP criteria, were not submitted to bacteriological testing. Escherichia coli (n = 7; 16.7%) was the pathogen most frequently isolated, with Citrobacter freundii, Listeria monocytogenis and Streptococcus salivarius being isolated once each (see Table 3). Twenty three (54.8%) patients had ascitic fluid total protein concentration
<1.5 g/dL at admission; survival in these patients, however, was not statistically different from those with higher protein concentration (p = 0.612; log rank test). Thirty one (73.8%) patients were treated with Ceftriaxone, three (7.14%) with Ciprofloxacin, one (2.38%) with Piperacilin/Tazobactam and one (2.38%) with Levofloxacin; there was no information regarding the antibiotic regimen used in the clinical records of six (14.28%) patients. Of those on Ceftriaxone, 10 (32.25%) did not respond to the treatment and were switched to another antibiotic (see Table 4). Of the 21 (50%) patients who repeated paracentesis during hospitalization, 19 (45.2%) had culture-negative ascitic fluid, one (2.4%) was positive for Escherichia coli and one (2.4%) for Enterococcus faecalis plus Aeromonas hydophila. The average length of
hospitalization was 16.10 ± 12.01 days, with men having a longer length stay (17.21 ± 12.65 Interleukin-2 receptor days) than women (11.38 ± 7.70 days). Yet, this difference was not statistically significant (p = 0.221). Regarding complications (see Table 5) registered during hospitalization, the presence of renal failure (RF) was associated with a higher mortality risk (OR = 8.1; p = 0.005; chi-square test), which is re-enforced by using the Cox regression (HR = 3.25; p = 0.063), suggesting a 3 times higher risk of death in these patients; there is statistical significance (p = 0.045; log rank test) when comparing the survival curves regarding the presence or absence of RF (see Fig. 1). The presence of septic shock was also associated with a higher mortality risk (OR = 54; p < 0.001; chi-square test), with a 9 times higher risk of death (HR = 9.5; p = 0.
