INTRODUCTION:Critically ill patients with cirrhosis admitted to the intensive care unit (ICU) are usually on broad-spectrum antibiotics because of suspected infection or as a hospital protocol. It is unclear if additional rifaximin has any synergistic effect with broad-spectrum antibiotics in ICU patients with acute overt hepatic encephalopathy (HE).METHODS:In this double-blind trial, patients with overt HE admitted to ICU were randomized to receive antibiotics (ab) alone or antibiotics with rifaximin (ab + r). Resolution (or 2 grade reduction) of HE, time to resolution of HE, in-hospital mortality, nosocomial infection, and changes in endotoxin levels were compared between the 2 groups. A subgroup analysis of patients with decompensated cirrhosis and acute-on-chronic liver failure was performed.RESULTS:Baseline characteristics and severity scores were similar among both groups (92 in each group). Carbapenems and cephalosporin with beta-lactamase inhibitors were the most commonly used ab. On Kaplan-Meier analysis, 44.6% (41/92; 95% confidence interval [CI], 32-70.5) in ab-only arm and 46.7% (43/92; 95% CI, 33.8-63) in ab + r arm achieved the primary objective (P = 0.84).Time to achieve the primary objective (3.65 ± 1.82 days and 4.11 ± 2.01 days; P = 0.27) and in-hospital mortality were similar among both groups (62% vs 50%; P = 0.13). Seven percent and 13% in the ab and ab + r groups developed nosocomial infections (P = 0.21). Endotoxin levels were unaffected by rifaximin. Rifaximin led to lower in-hospital mortality (hazard ratio: 0.39 [95% CI, 0.2-0.76]) in patients with decompensated cirrhosis but not in patients with acute-on-chronic liver failure (hazard ratio: 0.99 [95% CI, 0.6-1.63]) because of reduced nosocomial infections.DISCUSSION:Reversal of overt HE in those on ab was comparable with those on ab + r.

Background and Objectives Human albumin (HA) solution is currently recommended only for patients with spontaneous bacterial peritonitis (SBP) and acute kidney injury (AKI). However, its use in hospitalized patients is quite frequent. The objective was to compare the outcomes of patients receiving HA in recommended (Gr. A) vs. non-recommended (Gr. B) indications. Methods In this prospective study, consecutive hospitalized patients who received HA were included. Apart from comparing the proportion of patients achieving resolution of hyponatremia, infection and hepatic encephalopathy among Gr. A and Gr. B, we also compared the in-hospital survival and performed a sub-group analysis of patients with the European Association for the Study of the Liver (EASL) acute-on-chronic liver failure (ACLF) and decompensated cirrhosis (DC). Results Of the 396 hospitalized patients who received HA, 180 had AKI and/or SBP (Gr. A), and 216 received albumin for non-recommended indications (Gr. B). The mean age, sex and etiology distribution were similar. The total dose of HA was higher (88 ± 61.62 g vs. 71.31 ± 488.17 g; p  = 0.003) and the duration longer (4 ± 2.37 vs. 3.4 ± 1.82 days; p  = 0.005) in Gr. A than B. The resolution of infection and HE was similar among both groups, while hyponatremia resolution was significantly higher in Gr. B (94.7%) than Gr. A (75.6%; p  < 0.001). On Kaplan-Meier analysis, survival was significantly higher in Gr. B (94%) than Gr. A (78.9%; p  < 0.001). The incidence of albumin-induced fluid overload was comparable (2.8% vs. 1.4%; p  = 0.32). Patients with ACLF were sicker with a higher incidence of microbiologically proven infection, hepatic encephalopathy (HE) and hyponatremia than in the DC group. Resolution of infection and hyponatremia and in-hospital survival was significantly lower in the ACLF group (72.5%) than in the DC group (92.7%; p  < 0.001). Eighty-six per cent of patients achieved resolution of ACLF. Conclusions HA infusion is safe and effective even in patients without AKI and SBP and leads to the resolution of infection, hyponatremia, HE and ACLF. Graphical abstract
