Background and Aims: Little is known about the clinical characteristics and prognosis of hospitalized patients with moderate alcohol-associated hepatitis (mAH) as compared to severe alcohol-associated hepatitis (sAH). Therefore, we aimed to describe the clinical characteristics and risk factors associated with mortality in hospitalized mAH patients., Methods: Patients hospitalized with alcohol-associated hepatitis (AH) from 1 January 2010 to 31 December 2020 at a large US healthcare system [11 hospitals, one liver transplant centre] were retrospectively analysed for outcomes. Primary outcome was 90-day mortality. AH and mAH were defined according to NIAAA Alcoholic Hepatitis Consortia and Model for End-stage Liver Disease Score ≤ 20 respectively. Multivariable Cox regression analysis was performed to identify independent risk factors associated with 90-day mortality., Results: 1504 AH patients were hospitalized during the study period, of whom 39% (n = 590) had mAH. Compared to sAH patients, mAH patients were older (50 vs. 48 years, p < 0.001) and less likely to have underlying cirrhosis (74% vs. 83%, p < 0.001). There were no differences between the two groups for median alcohol intake g/day (mAH 140.0 vs. sAH 112.0, p = 0.071). The cumulative proportion surviving at 90 days was 88% in mAH versus 62% in sAH (p < 0.001). On multivariable analysis, older age [HR 1.03 (95% CI 1.00-1.06), p = 0.020], corticosteroid use [HR 1.80 (95% CI 1.06-3.06), p = 0.030] and acute kidney injury (AKI) [HR 2.43 (95% CI 1.33-4.47), p = 0.004] were independently associated with 90-day mortality., Conclusions: mAH carries a 12% mortality rate at 90 days. Age, AKI and corticosteroid use were associated with an increased risk for 90-day mortality. Avoidance of corticosteroids and strategies to reduce the risk of AKI could improve outcomes in mAH patients., (© 2023 The Authors. Liver International published by John Wiley & Sons Ltd.)

Background: The prognostic impact of acute kidney injury (AKI) recovery patterns in critically ill patients with cirrhosis is unknown. We aimed to compare mortality stratified by AKI recovery patterns and identify predictors of mortality in patients with cirrhosis and AKI admitted to the intensive care unit., Materials and Methods: Patients with cirrhosis and AKI from 2016 to 2018 at 2 tertiary care intensive care units were analyzed (N=322). AKI recovery was defined by Acute Disease Quality Initiative consensus: return of serum creatinine <0.3 mg/dL of baseline within 7 days of AKI onset. Recovery patterns were categorized by Acute Disease Quality Initiative consensus: 0-2 days, 3-7 days, and no-recovery (persistence of AKI >7 d). Landmark competing risk univariable and multivariable models (liver transplant as competing risk) was used to compare 90-day mortality between AKI recovery groups and to determine independent predictors of mortality., Results: Sixteen percent (N=50) and 27% (N=88) achieved AKI recovery within 0-2 and 3-7 days, respectively; 57% (N=184) had no-recovery. Acute on chronic liver failure was prevalent (83%) and patients with no-recovery were more likely to have grade 3 acute on chronic liver failure (N=95, 52%) compared to patients with AKI recovery [0-2: 16% (N=8); 3-7: 26% (N=23); p<0.001]. Patients with no-recovery had significantly higher probability of mortality [unadjusted-sub-HR (sHR): 3.55; 95% CI: 1.94-6.49; p<0.001] compared to patients with recovery within 0-2 days, while the probability was similar between 3-7 and 0-2 days (unadjusted-sub-HR: 1.71; 95% CI: 0.91-3.20; p=0.09). On multivariable analysis, AKI no-recovery (sub-HR: 2.07; 95% CI: 1.33-3.24; p=0.001), severe alcohol-associated hepatitis (sub-HR: 2.41; 95% CI: 1.20-4.83; p=0.01), and ascites (sub-HR: 1.60; 95% CI: 1.05-2.44; p=0.03) were independently associated with mortality., Conclusion: AKI no-recovery occurs in over half of critically ill patients with cirrhosis and AKI and is associated with worse survival. Interventions that facilitate AKI recovery may improve outcomes in this patient population., (Copyright © 2023 American Association for the Study of Liver Diseases.)

Objectives: Mean arterial pressure is critically important in patients with cirrhosis in the ICU, however, there is limited data to guide therapies and targets. Design: Retrospective observational study. Setting: Tertiary care ICU. Patients: Two hundred and seventy-three critically ill patients with cirrhosis. Interventions: None. Measurements and Main Results: We performed a comprehensive time-weighted mean arterial pressure analysis (time-weighted-average-mean arterial pressure and cumulative-time-below various mean arterial pressure-thresholds) during the first 24-hours after ICU admission (median: 25 mean arterial pressure measurements per-patient). Time-weighted-average-mean arterial pressure captures both the severity and duration of hypotension below a mean arterial pressure threshold and cumulative-time-below is the total time spent below a mean arterial pressure threshold. Individual univariable and multivariable logistic regression models were assessed for each time-weighted-average-mean arterial pressure and cumulative-time-below mean arterial pressure threshold (55, 60, 65, 70, and 75 mm Hg) for ICU-mortality. Time-weighted-average-mean arterial pressure: for 1 mm Hg decrease in mean arterial pressure below 75, 70, 65, 60, and 55 mm Hg, the odds for ICU-mortality were 14%, 18%, 26%, 41%, and 74%, respectively (p < 0.01, all thresholds). The association between time-weighted-average-mean arterial pressure and ICU-mortality for each threshold remained significant after adjusting for model for end-stage liver disease--sodium score, mechanical ventilation, vasopressor use, renal replacement therapy, grade 3/4 hepatic encephalopathy, WBC count, and albumin. Cumulative-time-below: odds for ICU-mortality were 4%, 6%, 10%, 12%, and 12% for each-hour spent below 75, 70, 65, 60, and 55 mm Hg, respectively. In the adjusted models, significant associations only remained for mean arterial pressure less than 65 mm Hg (odds ratio, 1.07; 95% CI, 1.00-1.14; p = 0.05) and < 60 mm Hg (odds ratio, 1.10; 95% CI, 1.01-1.18; p = 0.04). Conclusions: These data suggest that maintaining a mean arterial pressure of greater than 65 mm Hg may be a reasonable target in patients with cirrhosis admitted to the ICU. However, further prospective randomized trials are needed to determine the optimal mean arterial pressure-targets in this patient population. [ABSTRACT FROM AUTHOR]
