RESUMO
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.

Background & aims: Severe alcoholic hepatitis (SAH) is a grave condition, and the presence of acute kidney injury (AKI) further jeopardizes patient survival. However, the impact of AKI on survival in SAH has not been assessed from this region of Asia. Materials and methods: This study was conducted on consecutive alcohol-associated liver disease (ALD) patients hospitalized in Gastroenterology Department, SCB Medical College, Cuttack, India, between October 2016 and December 2018. On diagnosis of SAH (mDF score ≥32), demographic, clinical, and laboratory parameters were recorded, and survival was compared between patients with and without AKI (AKIN criteria). In addition, survival was compared among SAH patients defined by other criteria and prognostic models in the presence and absence of AKI. Results: 309 (70.71%) of ALD patients had SAH, and 201 (65%) of them had AKI. SAH patients with AKI had higher total leucocyte count, total bilirubin, serum creatinine, serum urea, INR, MELD (UNOS), MELD (Na+), CTP score, mDF score, Glasgow score, ABIC score, and increased prevalence of acute on chronic liver failure (ACLF) as per EASL-CLIF Consortium criteria (P < 0.001). Further, they had prolonged hospital stay, and increased death during hospitalization, at 28 days as well as 90 days (P < 0.001). Significant differences in survival were also seen in SAH (as per MELD, ABIC, and GAHS criteria) patients above the marked cut offs in respect to AKI. Conclusions: Over two-thirds of ALD patients had SAH, and about two-thirds had AKI. Patients with SAH and AKI had an increased prevalence of ACLF, longer hospital stay, and increased mortality during hospitalization at 28 days and 90 days. Lay summary: SAH is a critical condition, and the presence of AKI negatively affects their survival. Hence, early identification of SAH and AKI, as well as early initiation of treatment, is crucial for better survival. Our study from the coastal part of eastern India is the first to demonstrate the prevalence of SAH among patients with ALD along with the prevalence of AKI among SAH patients in this region. This knowledge will be helpful in managing these patients from this region of world.
RESUMO
BACKGROUND AND AIM: Plasma-exchange (PE) has improved survival in acute liver failure by ameliorating systemic inflammatory response syndrome (SIRS). We evaluated PE and compared it to Fractional Plasma Separation and Adsorption (FPSA) and standard medical treatment (SMT) in a large multinational cohort of ACLF patients. METHODS: Data were prospectively collected from the AARC database and analysed. Matching by propensity risk score (PRS) was performed. Competing risk survival analysis was done to identify deaths because of multiorgan failure (MOF). In a subset of 10 patients, we also evaluated the mechanistic basis of response to PE. RESULTS: ACLF patients (n = 1866, mean age 44.3 ± 12.3 yrs, 93% males, 65% alcoholics) received either artificial liver support (ALS) (n = 162); [PE (n = 131), FPSA (n = 31)] or were continued on standard medical therapy (SMT) (n = 1704). In the PRS-matched cohort (n = 208, [ALS-119; PE-94, FPSA-25)], SMT-89). ALS therapies were associated with a significantly higher resolution of SIRS (Odd's ratio 9.23,3.42-24.8), lower and delayed development of MOF (Hazard ratio 7.1, 4.5-11.1), and lower liver-failure-related deaths as compared to FPSA and SMT (P < .05). PE cleared inflammatory cytokines, damage-associated molecular patterns, and endotoxin in all patients. Responders improved monocyte phagocytic function and mitochondrial respiration and increased the anti-inflammatory cytokine interleukin-1 receptor antagonist (IL-1RA) compared to non-responders. PE was associated with lesser adverse effects as compared to FPSA. CONCLUSIONS: PE improves systemic inflammation and lowers the development of MOF in patients with ACLF. Plasma-exchange provides significant survival benefit over FPSA and could be a preferred modality of liver support for ACLF patients.

BACKGROUND AND AIM: Sepsis is an important determinant of the outcome of acute-on-chronic liver failure (ACLF) patients. Omega-3 fatty acids (FAs) are known to suppress inflammation, reduce morbidity, and mortality in postoperative and critically ill patients. We aimed to evaluate the effect of intravenous omega-6 and omega-3 FA lipid emulsions in ACLF patients. METHODS: Ninety ACLF patients were randomly allocated to three groups: Gr. A received no lipid emulsions, Gr. B received omega-6 FAs, and Gr. C received omega-3 FAs. The primary and secondary aims were to compare the effects of lipid emulsions on immune modulation, the incidence of bacterial sepsis, and mortality at day 28. RESULTS: The baseline characteristics of the patients were comparable. Serum endotoxin levels remained suppressed by 22% in Gr. C compared with a 4% and 12% rise in Gr. B and A (P < 0.001). Omega-3 FAs also suppressed C-reactive protein levels and neutrophil-to-lymphocyte ratio in Gr. C. Compared with Gr. A, omega-3 FAs reduced sepsis by 86% (HR, 0.14; 95% CI 0.04-0.43; P < 0.001). Omega-3 FAs significantly increased the expression of TLR2 and TLR4 on both CD14+ and CD16+ monocytes, and TLR4, on macrophages and neutrophils. There were no serious adverse events, except transient flushing in 20% and 16.6% of patients receiving omega-6 FAs and omega-3 FAs, respectively. CONCLUSION: Omega-3 FAs are safe and effective in reducing systemic inflammation, endotoxemia, and sepsis in patients with ACLF. These lipid emulsions could also be considered as effective sources of immunonutrition in such sick patients.

Background and Aims: Dengue infection is a major health burden, which can result in mild self-limited febrile illness to highly fatal hemorrhagic disease. There is paucity of literature describing the manifestations of dengue in patients with underlying liver disease. We studied and compared the manifestations of this tropical infection in patients with and without liver disease. Methods: Patients with serologically-confirmed dengue infection were included in this retrospective study, obtained for over a period of 1 year. Demographic and laboratory variables were compared for the individuals with no underlying liver disease (Group A, n = 71), chronic hepatitis (Group B, n = 12), and cirrhosis (Group C, n = 12). Results: Males predominated the study population (61%), with a higher mean age in the cirrhotic group. The most common clinical manifestation was classical dengue fever, seen in 89 individuals. Two presented as dengue hemorrhagic fever (1 each in Group A and Group B), 1 presented as acute liver failure, and 3 as acute-on-chronic liver failure. Hemoconcentration was less evident in Group C as compared to Group A and Group B (p < 0.001). Patients in Group C had significantly prolonged International Normalized Ratio (INR) and enhanced thrombocytopenia compared to patients in Group A and Group B. Patients in Group C also required prolonged hospital stay (Group A: 4.83 ± 2.88, Group B: 7.33 ± 2.3, Group C: 13 ± 5 days; p < 0.001). Three patients expired in Group C compared to the 1 in Group A and none in Group B (p = 0.01). On univariate analysis, hemoglobin, albumin, INR, and bilirubin predicted development of liver failure. On multivariate analysis, INR and bilirubin predicted development of liver failure. Conclusions: Dengue infection can have varied manifestations, ranging from simple fever to acute-on-chronic liver failure and acute liver failure. Cirrhotic patients lack classical features of dengue and have relatively poor prognosis. Dengue should be suspected as a cause of liver failure in endemic areas, where no etiological cause is discernible.
