Global disparities in mortality and liver transplantation in hospitalised patients with cirrhosis: a prospective cohort study for the CLEARED Consortium.

BACKGROUND: Cirrhosis, the end result of liver injury, has high mortality globally. The effect of country-level income on mortality from cirrhosis is unclear. We aimed to assess predictors of death in inpatients with cirrhosis using a global consortium focusing on cirrhosis-related and access-related variables. METHODS: In this prospective observational cohort study, the CLEARED Consortium followed up inpatients with cirrhosis at 90 tertiary care hospitals in 25 countries across six continents. Consecutive patients older than 18 years who were admitted non-electively, without COVID-19 or advanced hepatocellular carcinoma, were enrolled. We ensured equitable participation by limiting enrolment to a maximum of 50 patients per site. Data were collected from patients and their medical records, and included demographic characteristics; country; disease severity (MELD-Na score); cirrhosis cause; medications used; reasons for admission; transplantation listing; cirrhosis-related history in the past 6 months; and clinical course and management while hospitalised and for 30 days post discharge. Primary outcomes were death and receipt of liver transplant during index hospitalisation or within 30 days post discharge. Sites were surveyed regarding availability of and access to diagnostic and treatment services. Outcomes were compared by country income level of participating sites, defined according to World Bank income classifications (high-income countries [HICs], upper-middle-income countries [UMICs], and low-income or lower-middle-income countries [LICs or LMICs]). Multivariable models controlling for demographic variables, disease cause, and disease severity were used to analyse the odds of each outcome associated with variables of interest. FINDINGS: Patients were recruited between Nov 5, 2021, and Aug 31, 2022. Complete inpatient data were obtained for 3884 patients (mean age 55·9 years [SD 13·3]; 2493 (64·2%) men and 1391 (35·8%) women; 1413 [36·4%] from HICs, 1757 [45·2%] from UMICs, and 714 [18·4%] from LICs or LMICs), with 410 lost to follow-up within 30 days after hospital discharge. The number of patients who died while hospitalised was 110 (7·8%) of 1413 in HICs, 182 (10·4%) of 1757 in UMICs, and 158 (22·1%) of 714 in LICs and LMICs (p<0·0001), and within 30 days post discharge these values were 179 (14·4%) of 1244 in HICs, 267 (17·2%) of 1556 in UMICs, and 204 (30·3%) of 674 in LICs and LMICs (p<0·0001). Compared with patients from HICs, increased risk of death during hospitalisation was found for patients from UMICs (adjusted odds ratio [aOR] 2·14 [95% CI 1·61-2·84]) and from LICs or LMICs (2·54 [1·82-3·54]), in addition to increased risk of death within 30 days post discharge (1·95 [1·44-2·65] in UMICs and 1·84 [1·24-2·72] in LICs or LMICs). Receipt of a liver transplant was recorded in 59 (4·2%) of 1413 patients from HICs, 28 (1·6%) of 1757 from UMICs (aOR 0·41 [95% CI 0·24-0·69] vs HICs), and 14 (2·0%) of 714 from LICs and LMICs (0·21 [0·10-0·41] vs HICs) during index hospitalisation (p<0·0001), and in 105 (9·2%) of 1137 patients from HICs, 55 (4·0%) of 1372 from UMICs (0·58 [0·39-0·85] vs HICs), and 16 (3·1%) of 509 from LICs or LMICs (0·21 [0·11-0·40] vs HICs) by 30 days post discharge (p<0·0001). Site survey results showed that access to important medications (rifaximin, albumin, and terlipressin) and interventions (emergency endoscopy, liver transplantation, intensive care, and palliative care) varied geographically. INTERPRETATION: Inpatients with cirrhosis in LICs, LMICs, or UMICs have significantly higher mortality than inpatients in HICs independent of medical risk factors, and this might be due to disparities in access to essential diagnostic and treatment services. These results should encourage researchers and policy makers to consider access to services and medications when evaluating cirrhosis-related outcomes.

The road to pandemic recovery: Tracking COVID-19's impact on cirrhosis care and outcomes among 111,558 Veterans.

BACKGROUND AIMS: This study aimed to evaluate quarterly trends in process and health outcomes among Veterans with cirrhosis and assess the factors associated with cirrhosis outcomes before and during the COVID-19 pandemic. APPROACH RESULTS: US Veterans with cirrhosis were identified using the Veterans Health Administration Corporate Data Warehouse. Quarterly measures were evaluated from September 30, 2018, through March 31, 2022, including twice yearly screening for hepatocellular carcinoma (HCC-6), new HCC, surveillance for or treatment of esophageal varices, variceal bleeding, all-cause hospitalization, and mortality. Joinpoint analyses were used to assess the changes in trends over time. Logistic regression models were used to identify the demographic and medical factors associated with each outcome over time. Among 111,558 Veterans with cirrhosis with a mean Model for End-stage Liver Disease-Sodium of 11±5, rates of HCC-6 sharply declined from a prepandemic peak of 41%, to a nadir of 28%, and rebounded to 36% by March 2022. All-cause mortality did not significantly change over the pandemic, but new HCC diagnosis, EVST, variceal bleeding, and all-cause hospitalization significantly declined over follow-up. Quarterly HCC diagnosis declined from 0.49% to 0.38%, EVST from 50% to 41%, variceal bleeding from 0.15% to 0.11%, and hospitalization from 9% to 5%. Rurality became newly, significantly associated with nonscreening over the pandemic (aOR for HCC-6=0.80, 95% CI 0.74 to 0.86; aOR for EVST=0.95, 95% CI 0.90 to 0.997). CONCLUSIONS: The pandemic continues to impact cirrhosis care. Identifying populations at the highest risk of care disruptions may help to address ongoing areas of need.

Reduction in Nosocomial Infections in Patients With Cirrhosis During the COVID-19 Era Compared with Pre-COVID-19: Impact of Masking and Restricting Visitation.

Nosocomial infections (NIs) in critically ill patients with cirrhosis result in higher death and transplant delisting. NIs are promoted by staff, visitors, and the environment, all of which were altered to reduce pathogen transmission after COVID-19. Two cohorts of intensive care unit patients with cirrhosis from March 2019 to February 2020 (pre-COVID, n = 234) and March 2020 to March 2021 (COVID era, n = 296) were included. We found that despite a higher admission MELD-Na, qSOFA, and WBC count and requiring a longer intensive care unit stay, COVID-era patients developed lower NIs (3% vs 10%, P < 0.001) and had higher liver transplant rates vs pre-COVID patients. COVID-era restrictions could reduce NIs in critically ill patients with cirrhosis.

Development of New Mental and Physical Health Sequelae among US Veterans after COVID-19.

Background:COVID-19 sequelae among veterans need evaluation. Design: Propensity-score-matched retrospective cohort study. Participants: A total 778,738 veterans, who were tested for COVID-19 at VA facilities between 20 February 2020-27 March 2021. Main Outcomes: Development of new physical and mental health conditions (incidence) during the follow-up period of 7 days to 3 months after the diagnosis of COVID-19. Results: Out of 778,738 veterans, 149,205 (19.2%) were inpatients and 629,533 (80.8%) were outpatients. 123,757 (15.9%) diagnosed with COVID-19. Mean age was 61 ± 15.4, mostly men (89%) who were White (68%) and non-Hispanic (88%). In hospitalized patients, COVID-19 is associated with significantly higher incidences of physical conditions (venous thromboembolism (5.8% vs. 2.9%, p < 0.001), pulmonary circulation disorder (5.1% vs. 2.9%, p < 0.001), chronic lung disease (8.4% vs. 4.3%, p < 0.001), acute kidney injury (16.4% vs. 9.3%, p < 0.001), chronic kidney disease (6.5% vs. 4.8%, p < 0.001), cardiac arrhythmia (15.2% vs. 10.9%, p < 0.001), complicated hypertension (12% vs. 8.5%, p < 0.001), coagulopathy (6.1% vs. 2.6%, p < 0.001), fluid/electrolyte disorders (24.4% vs. 12.6%, p < 0.001) and neurological disorders (7.1% vs. 3.8%, p < 0.001)) and mental health conditions (depressive episode (6.6% vs. 4.3%, p < 0.001), adjustment disorder (2.5% vs. 1.7%, p < 0.001), insomnia (4.9% vs. 3.2%, p < 0.001) and dementia (3.0% vs. 1.9%, p < 0.001)) compared to propensity-matched hospitalized COVID-19 negative patients. In outpatient settings, COVID-19 diagnosis is associated with smaller increase in the incidences of the physical sequelae. Conclusions: In this propensity-score-matched analysis of US veterans, COVID-19 survivors, especially those who were hospitalized, developed new physical and mental health sequelae at a significantly higher rate than those without COVID-19.

Natural History of Alcohol-Associated Liver Disease: Understanding the Changing Landscape of Pathophysiology and Patient Care.

Alcohol use and consequent liver disease are major burdens that have worsened during the COVID-19 pandemic. There are several facets to the pathophysiology and clinical consequences of alcohol-use disorder (AUD) and progression to alcohol-associated liver disease (ALD) that require a concerted effort by clinicians and translational and basic science investigators. Several recent advances from bedside to bench and bench to bedside have been made in ALD. We focused this review on a case-based approach that provides a human context to these important advances across the spectrum of ALD.

Fibrosis-4 Predicts the Need for Mechanical Ventilation in a National Multiethnic Cohort of Corona Virus Disease 2019.

Simple tests of routine data are needed for those with severe acute respiratory syndrome coronavirus 2, which causes corona virus disease 2019 (COVID-19), to help identify those who may need mechanical ventilation (MV). In this study, we aimed to determine if fibrosis-4 (FIB-4) is associated with the need for MV in patients with COVID-19 and if there is an association to determine the optimal FIB-4 cutoff. This was a retrospective, national, multiethnic cohort study of adults seen in an ambulatory or emergency department setting who were diagnosed with COVID-19. We used the TriNetX platform for analysis. Measures included demographics, comorbid diseases, and routine laboratory tests. A total of 4,901 patients with COVID-19 were included. Patients had a mean age of 56, 48% were women, 42% were obese, 38% were white, 40% were black, 15% had cardiac disease, 39% had diabetes mellitus, 20% had liver disease, and 50% had respiratory disease. The need for MV was 6%. The optimal FIB-4 cutoff for the need for MV was 3.04 (area under the curve, 0.735), which had sensitivity, specificity, and positive and negative predictive values of 42%, 77%, 11%, and 95%, respectively, with 93% accuracy. When stratified by race, increased FIB-4 remained associated with the need for MV in both white and black patients. Conclusion: FIB-4 can be used by frontline providers to identify patients that may require MV.

A Randomized Clinical Trial of Fecal Microbiota Transplant for Alcohol Use Disorder.

BACKGROUND AND AIMS: Alcohol use disorder (AUD) is associated with microbial alterations that worsen with cirrhosis. Fecal microbiota transplant (FMT) could be a promising approach. APPROACH AND RESULTS: In this phase 1, double-blind, randomized clinical trial, patients with AUD-related cirrhosis with problem drinking (AUDIT-10 > 8) were randomized 1:1 into receiving one placebo or FMT enema from a donor enriched in Lachnospiraceae and Ruminococcaceae. Six-month safety was the primary outcome. Alcohol craving questionnaire, alcohol consumption (urinary ethylglucuronide/creatinine), quality of life, cognition, serum IL-6 and lipopolysaccharide-binding protein, plasma/stool short-chain fatty acids (SCFAs), and stool microbiota were tested at baseline and day 15. A 6-month follow-up with serious adverse event (SAE) analysis was performed. Twenty patients with AUD-related cirrhosis (65 ± 6.4 years, all men, Model for End-Stage Liver Disease 8.9 ± 2.7) with similar demographics, cirrhosis, and AUD severity were included. Craving reduced significantly in 90% of FMT versus 30% in placebo at day 15 (P = 0.02) with lower urinary ethylglucuronide/creatinine (P = 0.03) and improved cognition and psychosocial quality of life. There was reduction in serum IL-6 and lipopolysaccharide-binding protein and increased butyrate/isobutyrate compared with baseline in FMT but not placebo. Microbial diversity increased with higher Ruminococcaceae and other SCFAs, producing taxa following FMT but not placebo, which were linked with SCFA levels. At 6 months, patients with any SAEs (8 vs. 2, P = 0.02), AUD-related SAEs (7 vs. 1, P = 0.02), and SAEs/patient (median [interquartile range], 1.5 [1.25] vs. 0 [0.25] in FMT, P = 0.02) were higher in placebo versus FMT. CONCLUSIONS: This phase 1 trial shows that FMT is safe and associated with short-term reduction in alcohol craving and consumption with favorable microbial changes versus placebo in patients with alcohol-associated cirrhosis with alcohol misuse. There was also a reduction in AUD-related events over 6 months in patients assigned to FMT.

Comparison of mortality risk in patients with cirrhosis and COVID-19 compared with patients with cirrhosis alone and COVID-19 alone: multicentre matched cohort.

OBJECTIVE: Comorbid conditions are associated with poor prognosis in COVID-19. Registry data show that patients with cirrhosis may be at high risk. However, outcome comparisons among patients with cirrhosis+COVID-19 versus patients with COVID-19 alone and cirrhosis alone are lacking. The aim of this study was to perform these comparisons. DESIGN: A multicentre study of inpatients with cirrhosis+COVID-19 compared with age/gender-matched patients with COVID-19 alone and cirrhosis alone was performed. COVID-19 and cirrhosis characteristics, development of organ failures and acute-on-chronic liver failure (ACLF) and mortality (inpatient death+hospice) were compared. RESULTS: 37 patients with cirrhosis+COVID-19 were matched with 108 patients with COVID-19 and 127 patients with cirrhosis from seven sites. Race/ethnicity were similar. Patients with cirrhosis+COVID-19 had higher mortality compared with patients with COVID-19 (30% vs 13%, p=0.03) but not between patients with cirrhosis+COVID-19 and patients with cirrhosis (30% vs 20%, p=0.16). Patients with cirrhosis+COVID-19 versus patients with COVID-19 alone had equivalent respiratory symptoms, chest findings and rates of intensive care unit transfer and ventilation. However, patients with cirrhosis+COVID-19 had worse Charlson Comorbidity Index (CCI 6.5±3.1 vs 3.3±2.5, p<0.001), lower presenting GI symptoms and higher lactate. Patients with cirrhosis alone had higher cirrhosis-related complications, maximum model for end-stage liver disease (MELD) score and lower BiPAP/ventilation requirement compared with patients with cirrhosis+COVID-19, but CCI and ACLF rates were similar. In the entire group, CCI (OR 1.23, 95% CI 1.11 to 1.37, p<0.0001) was the only variable predictive of mortality on multivariable regression. CONCLUSIONS: In this multicentre North American contemporaneously enrolled study, age/gender-matched patients with cirrhosis+COVID-19 had similar mortality compared with patients with cirrhosis alone but higher than patients with COVID-19 alone. CCI was the only independent mortality predictor in the entire matched cohort.
