AIMTo analyze whether fluid overload is an independent risk factor of adverse outcomes after liver transplantation (LT).METHODSOne hundred and twenty-one patients submitted to LT were retrospectively evaluated. Data regarding perioperative and postoperative variables previously associated with adverse outcomes after LT were reviewed. Cumulative fluid balance (FB) in the first 12 h and 4 d after surgery were compared with major adverse outcomes after LT.RESULTSMost of the patients were submitted to a liberal approach of fluid administration with a mean cumulative FB over 5 L and 10 L, respectively, in the first 12 h and 4 d after LT. Cumulative FB in 4 d was independently associated with occurrence of both AKI and requirement for renal replacement therapy (RRT) (OR = 2.3; 95%CI: 1.37-3.86, P = 0.02 and OR = 2.89; 95%CI: 1.52-5.49, P = 0.001 respectively). Other variables on multivariate analysis associated with AKI and RRT were, respectively, male sex and Acute Physiology and Chronic Health Disease Classification System (APACHE II) levels and sepsis or septic shock. Mortality was shown to be independently related to AST and APACHE II levels (OR = 2.35; 95%CI: 1.1-5.05, P = 0.02 and 2.63; 95%CI: 1.0-6.87, P = 0.04 respectively), probably reflecting the degree of graft dysfunction and severity of early postoperative course of LT. No effect of FB on mortality after LT was disclosed.CONCLUSIONCumulative positive FB over 4 d after LT is independently associated with the development of AKI and the requirement of RRT. Survival was not independently related to FB, but to surrogate markers of graft dysfunction and severity of postoperative course of LT.

Leukocyte biomarkers, including the neutrophil-to-lymphocyte (NLR), monocyte-tolymphocyte-(MLR), platelet-to-lymphocyte (PLR) ratios and systemic immune-inflammation index (SII) have been associated with severity and mortality of patients with COVID-19. The purpose of this study was to evaluate the association of baseline leukocyte biomarkers calculated in the emergency department (ED) with the disease severity and mortality. This was a retrospective cohort study that evaluated 1,535 (mean age 57+18 years) patients with SARS-CoV-2 infection in the ED of a single reference center. Outcomes were severity, defined as intensive care unit (ICU) admission requirement, and in-hospital mortality. All leukocyte biomarkers were calculated in the ED before the hospital admission. Their ability to predict the severity and mortality was measured using receiver operating characteristic (ROC) curves. Severity and mortality were observed in 30.9% and 12.6% of the patients, respectively, and were significantly correlated with NLR, MLR, PLR and SII, but only NLR was independently associated with both outcomes on multivariate analysis. Analysis of ROC curves revealed that NLR (0.78 for severity and 0.80 for mortality) and SII (0.77 for severity and 0.75 for mortality) had the best ability to predict mortality, when compared to other ratios. The highest AUC was observed for NLR, employing cut-off points of 5.4 for severity and 5.5 for mortality. Leukocyte biomarkers, particularly NLR, are capable of predicting the severity and mortality of patients with SARS-CoV-2 infection and could be important adjunct tools to identify patients in the ED that are more prone to develop adverse outcomes.

Background Bacterial infections occur in 43—59% of cirrhotic patients admitted to the intensive care unit with impact in morbidity and mortality. An increase in the frequency of multidrug-resistant (MDRO) and extensively drug-resistant (XDRO) organisms has been described in bacterial infections in cirrhotic patients with an adverse impact on survival. Objective To characterize community-acquired (CA), healthcare-associated (HCA), and hospital-acquired (HA) infections in cirrhotic patients and their impact in the occurrence of adverse outcomes. Methods This study included all cirrhotic patients admitted in an intensive care unit specialized in liver and gastrointestinal diseases in Brazil between January 2012 and June 2018. Frequency and topography of infections were retrospectively evaluated, as well as the frequency of MDRO and XDRO organisms, and their impact in occurrence of acute kidney injury, hepatorenal syndrome, acute-on-chronic liver failure, sepsis and mortality. Results A total of 374 infections were observed and classified as CA (22%), HCA (34%) and hospital-acquired (44%). Eighty-nine (54%) episodes of hospital-acquired infections were second infections. Spontaneous bacterial peritonitis (32%) and urinary tract infection (23%) were the most common infections. Culture-proven infections were positive in 61% of the cases, mainly gram-negative bacteria (73%). Acute kidney injury, hepatorenal syndrome and sepsis were observed, respectively, in 48%, 15% and 53% of the cases. MDRO and XDRO were seen, respectively, in 35% and 16%, mainly in HCA (48% vs 26% in CA infections, P=0.02) and hospital-acquired (58% vs 26% in CA infections, P=0.0009). Adverse outcomes were more frequently observed in subjects with hospital-acquired infections when compared to HCA and CA infections. Hospital-acquired, HCA and second infections were independently associated with in-hospital mortality. Conclusion Hospital-acquired, HCA and second infections are increasingly associated with either MDRO and/or XDRO and are independent predictors of in-hospital mortality. Their recognition and proper selection of appropriate empiric antibiotic regimens are important measures to reduce in-hospital mortality.
