ABSTRACT

BACKGROUND AND AIMS: Patients with Child-Turcotte-Pugh class B and C cirrhosis with upper gastrointestinal bleeding (UGIB) have systemic as well as localized (in the mucosa of the esophagus and stomach) fibrinolysis. The aim of this study was to evaluate the efficacy and safety of tranexamic acid in the treatment of acute UGIB in patients with cirrhosis. APPROACH AND RESULTS: A total of 600 patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB were randomly allocated to either the tranexamic acid (n=300) or the placebo group (n=300). The primary outcome measure was the proportion of patients developing 5-day treatment failure. Failure to control bleeding by day 5 was seen in 19/300 (6.3%) patients in the tranexamic acid group and 40/300 (13.3%) patients in the placebo group ( p =0.006). Esophageal endoscopic variceal ligation (EVL) site as a source of failure to control bleeding by day 5 among patients undergoing first-time esophageal EVL (excluding patients with a previous post-EVL ulcer as a source of bleed) was seen in 11/222 (4.9%) patients in the tranexamic acid group and 27/225 (1212.0%) patients in the placebo group ( p =0.005). However, 5-day and 6-week mortality was similar in the tranexamic acid and placebo groups. CONCLUSIONS: Tranexamic acid significantly reduces the failure to control bleeding by day 5 and failure to prevent rebleeding after day 5 to 6 weeks in patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB, by preventing bleeding from the EVL site.

ABSTRACT

BACKGROUND AND AIMS: Alcohol-associated hepatitis (AH) poses significant short-term mortality. Existing prognostic models lack precision for 90-day mortality. Utilizing artificial intelligence in a global cohort, we sought to derive and validate an enhanced prognostic model. APPROACH AND RESULTS: The Global AlcHep initiative, a retrospective study across 23 centers in 12 countries, enrolled patients with AH per National Institute for Alcohol Abuse and Alcoholism criteria. Centers were partitioned into derivation (11 centers, 860 patients) and validation cohorts (12 centers, 859 patients). Focusing on 30 and 90-day postadmission mortality, 3 artificial intelligence algorithms (Random Forest, Gradient Boosting Machines, and eXtreme Gradient Boosting) informed an ensemble model, subsequently refined through Bayesian updating, integrating the derivation cohort's average 90-day mortality with each center's approximate mortality rate to produce posttest probabilities. The ALCoholic Hepatitis Artificial INtelligence Ensemble score integrated age, gender, cirrhosis, and 9 laboratory values, with center-specific mortality rates. Mortality was 18.7% (30 d) and 27.9% (90 d) in the derivation cohort versus 21.7% and 32.5% in the validation cohort. Validation cohort 30 and 90-day AUCs were 0.811 (0.779-0.844) and 0.799 (0.769-0.830), significantly surpassing legacy models like Maddrey's Discriminant Function, Model for End-Stage Liver Disease variations, age-serum bilirubin-international normalized ratio-serum Creatinine score, Glasgow, and modified Glasgow Scores ( p < 0.001). ALCoholic Hepatitis Artificial INtelligence Ensemble score also showcased superior calibration against MELD and its variants. Steroid use improved 30-day survival for those with an ALCoholic Hepatitis Artificial INtelligence Ensemble score > 0.20 in both derivation and validation cohorts. CONCLUSIONS: Harnessing artificial intelligence within a global consortium, we pioneered a scoring system excelling over traditional models for 30 and 90-day AH mortality predictions.

ABSTRACT

BACKGROUND & AIMS: Widespread use of direct-acting antivirals for hepatitis C virus infection has been paralleled with increased numbers of patients with hepatocellular carcinoma (HCC) after achieving sustained virologic response (post-SVR HCC) worldwide. Few data compare regional differences in the presentation and prognosis of patients with post-SVR HCC. METHODS: We identified patients with advanced fibrosis (F3/F4) who developed incident post-SVR HCC between March 2015 and October 2021 from 30 sites in Europe, North America, South America, the Middle East, South Asia, East Asia, and Southeast Asia. We compared patient demographics, liver dysfunction, and tumor burden by region. We compared overall survival by region using Kaplan-Meier analysis and identified factors associated with survival using multivariable Cox regression analysis. RESULTS: Among 8796 patients with advanced fibrosis or cirrhosis who achieved SVR, 583 (6.6%) developed incident HCC. There was marked regional variation in the proportion of patients detected by surveillance (range: 59.5%-100%), median maximum tumor diameter (range, 1.8-5.0 cm), and the proportion with multinodular HCC (range, 15.4%-60.8%). The prognosis of patients highly varied by region (hazard ratio range, 1.82-9.92), with the highest survival rates in East Asia, North America, and South America, and the lowest survival rates in the Middle East and South Asia. After adjusting for geographic region, HCC surveillance was associated with early stage detection (Barcelona Clinic Liver Cancer stage 0/A, 71.0% vs 21.3%; P < .0001) and lower mortality rates (adjusted hazard ratio, 0.29; 95% CI, 0.18-0.46). CONCLUSIONS: Clinical characteristics, including early stage detection, and prognosis of post-SVR HCC differed significantly across geographic regions. Surveillance utilization appears to be a high-yield intervention target to improve prognosis among patients with post-SVR HCC globally.

ABSTRACT

BACKGROUND AND AIMS: With distinct mechanisms of action, the combination of tropifexor (TXR) and cenicriviroc (CVC) may provide an effective treatment for NASH. This randomized, multicenter, double-blind, phase 2b study assessed the safety and efficacy of TXR and CVC combination, compared with respective monotherapies. APPROACH AND RESULTS: Patients (N = 193) were randomized 1:1:1:1 to once-daily TXR 140 µg (TXR 140 ), CVC 150 mg (CVC), TXR 140 µg + CVC 150 mg (TXR 140 + CVC), or TXR 90 µg + CVC 150 mg (TXR 90 + CVC) for 48 weeks. The primary and secondary end points were safety and histological improvement, respectively. Rates of adverse events (AEs) were similar across treatment groups. Pruritus was the most frequently experienced AE, with highest incidence in the TXR 140 group (40.0%). In TXR and combination groups, alanine aminotransferase (ALT) decreased from baseline to 48 weeks (geometric mean change: -21%, TXR 140 ; -16%, TXR 140 + CVC; -13%, TXR 90 + CVC; and +17%, CVC). Reductions in body weight observed at week 24 (mean changes from baseline: TXR 140 , -2.5 kg; TXR 140 + CVC, -1.7 kg; TXR 90 + CVC, -1.0 kg; and CVC, -0.1 kg) were sustained to week 48. At least 1-point improvement in fibrosis stage/steatohepatitis resolution without worsening of fibrosis was observed in 32.3%/25.8%, 31.6%/15.8%, 29.7%/13.5%, and 32.5%/22.5% of patients in the TXR 140 , CVC, TXR 140 + CVC, and TXR 90 + CVC groups, respectively. CONCLUSIONS: The safety profile of TXR + CVC combination was similar to respective monotherapies, with no new signals. TXR monotherapy showed sustained ALT and body weight decreases. No substantial incremental efficacy was observed with TXR + CVC combination on ALT, body weight, or in histological end points compared with monotherapy.

ABSTRACT

BACKGROUND: Severe alcohol-associated hepatitis (SAH) presenting as acute-on-chronic liver failure (ACLF) has high mortality. Severe hepatic inflammation and ongoing hepatocellular cell death lead to rapid rise in portal pressure, a hyperdynamic circulation that might precipitate infections and organ failures. METHODS: Consecutive SAH patients were classified based on baseline HVPG measurement as 6to < 12 mmHg, 12to < 20 mmHg, and ≥ 20 mmHg. We analyzed portal hypertension severity in relation to fibrosis stage, ACLF at presentation, response to prednisolone, severity scores(MELD and Maddrey's Discriminant Function, mDF), and 90-day mortality. RESULTS: Of 819 SAH patients (94.6% ACLF, 85.4% histological cirrhosis, median MELD and mDF scores 25 and 66, respectively), 250(30.5%) had HVPG ≥ 20 mmHg. Patients with HVPG ≥ 20 mmHg more often had large esophageal varices (25.2%vs.13.2%; p-0.001), higher baseline MELD (27.1 ± 5.6vs.25.3 ± 5.2; p-0.001), and mDF(76.1 ± 16vs.68.4 ± 15.1; p-0.01) scores. No patient without ACLF had HVPG ≥ 20 mmHg. Moreover, during hospital course these patients had higher incidence of variceal bleed (17.2%vs.8.8%; p-0.001), acute kidney injury (36.4%vs.25.3%; p-0.001), and spontaneous bacterial peritonitis (6.4%vs.3.5%; p-0.05). Of 412(50.3%) eligible patients treated with prednisolone, 69.2% showed response at day 7(Lille's score < 0.45). 90-day mortality was 27.6%; and baseline MELD > 25.5[HR 1.78], HVPG ≥ 20 mmHg [HR 1.86], the presence of HE[HR 1.63], and prednisolone ineligibility due to sepsis[HR 1.27] were independent predictors. Mortality was unrelated to varices grade, variceal bleed, and histological cirrhosis. Repeat HVPG performed in 114(19.2%) patients after a median of 5.2 months showed significant decrease (3.6 mmHg; p-0.001) which correlated with improvement in MELD score(13points; p-0.05). CONCLUSION: Development of ACLF and complications in SAH are likely a result of acute rise in HVPG. "High-risk" SAH are SAH patients with HVPG ≥ 20 mmHg in the presence of ascites. Understanding the drivers for acute rise in portal pressure in SAH ACLF might help introduction of newer therapies.

ABSTRACT

BACKGROUND: Post-transjugular intrahepatic portosystemic shunt (TIPS) liver failure (PTLF) is a serious complication of TIPS procedure with poor patient prognosis. This study tried to investigate the incidence of PTLF following elective TIPS procedure and evaluated possible predictive factors for the same. METHODS: A retrospective analysis of patients who underwent elective TIPS placement between 2012 and 2022 and was conducted to determine development of PTLF (≥ 3-fold bilirubin and/or ≥ 2-fold INR elevation from the baseline) within 30 days following TIPS procedure. Medical record review was done and factors predicting development of PTLF and the 90-day transplant-free survival was determined. RESULTS: Thirty of 352 (8.5%) patients developed PTLF within 30 days of TIPS (mean age 54.2 ± 9.8 years, 83% male). The etiology of cirrhosis was related to non-alcoholic steatohepatitis (NASH) in 50%, alcohol in 33.3%, and hepatitis B/C virus infection in 16.7% of the patients. The mean Child-Turcotte-Pugh (CTP) score was 9.5 ± 1.2 and mean model for end stage liver disease (MELD) score was 14.6 ± 4.5 at the time of admission in patients who developed PTLF. The indication for TIPS was recurrent variceal bleed in 50% (15 of 30) and refractory ascites in 46.7% (14 of 30) patients with PTLF. Multivariate analysis identified prior HE (OR 6.1; CI 2.57-14.5, p < 0.0001) and higher baseline CTP score (OR 1.47; CI 1.07-2.04; p = 0.018) as predictors of PTLF. PTLF was associated with significantly lower 90-day transplant-free survival, as compared to patients without PTLF (40% versus 96%, p < 0.001). CONCLUSION: Almost 10% of patients with cirrhosis develop post-TIPS liver failure and is associated with significant early mortality and morbidity. Higher baseline CTP score and prior HE were identified as predictors for PTLF.

ABSTRACT

Pregnancy being an immune compromised state, coronavirus disease of 2019 (COVID-19) disease poses high risk of premature delivery and threat to fetus. Plasma metabolome regulates immune cellular responses, therefore we aimed to analyze the change in plasma secretome, metabolome, and immune cells with disease severity in COVID-19 positive pregnant females and their cord blood. COVID-19 reverse transcriptase-polymerase chain reaction positive pregnant females (n = 112) with asymptomatic (Asy) (n = 82), mild (n = 21), or moderate (n = 9) disease, healthy pregnant (n = 18), COVID-19 positive nonpregnant females (n = 7) were included. Eighty-two cord blood from COVID-19 positive and seven healthy cord blood were also analyzed. Mother's peripheral blood and cord blood were analyzed for untargeted metabolome profiling and cytokines by using high-resolution mass spectrometry and cytokine bead array. Immune scan was performed only in mothers' blood by flow cytometry. In Asy severe acute respiratory syndrome coronavirus 2 infection, the amino acid metabolic pathways such as glycine, serine, l-lactate, and threonine metabolism were upregulated with downregulation of riboflavin and tyrosine metabolism. However, with mild-to-moderate disease, the pyruvate and nicotinamide adenine dinucleotide (NAD+ ) metabolism were mostly altered. Cord blood mimicked the mother's metabolomic profiles by showing altered valine, leucine, isoleucine, glycine, serine, threonine in Asy and NAD+ , riboflavin metabolism in mild and moderate. Additionally, with disease severity tumor necrosis factor-α, interferon (IFN)-α, IFN-γ, interleukin (IL)-6 cytokine storm, IL-9 was raised in both mothers and neonates. Pyruvate, NAD metabolism and increase in IL-9 and IFN-γ had an impact on nonclassical monocytes, exhausted T and B cells. Our results demonstrated that immune-metabolic interplay in mother and fetus is influenced with increase in IL-9 and IFN-γ regulated pyruvate, lactate tricarboxylic acid, and riboflavin metabolism with context to disease severity.

ABSTRACT

BACKGROUND AND AIMS: We hypothesized that artificial intelligence (AI) models are more precise than standard models for predicting outcomes in acute-on-chronic liver failure (ACLF). METHODS: We recruited ACLF patients between 2009 and 2020 from APASL-ACLF Research Consortium (AARC). Their clinical data, investigations and organ involvement were serially noted for 90-days and utilized for AI modelling. Data were split randomly into train and validation sets. Multiple AI models, MELD and AARC-Model, were created/optimized on train set. Outcome prediction abilities were evaluated on validation sets through area under the curve (AUC), accuracy, sensitivity, specificity and class precision. RESULTS: Among 2481 ACLF patients, 1501 in train set and 980 in validation set, the extreme gradient boost-cross-validated model (XGB-CV) demonstrated the highest AUC in train (0.999), validation (0.907) and overall sets (0.976) for predicting 30-day outcomes. The AUC and accuracy of the XGB-CV model (%Δ) were 7.0% and 6.9% higher than the standard day-7 AARC model (p < .001) and 12.8% and 10.6% higher than the day 7 MELD for 30-day predictions in validation set (p < .001). The XGB model had the highest AUC for 7- and 90-day predictions as well (p < .001). Day-7 creatinine, international normalized ratio (INR), circulatory failure, leucocyte count and day-4 sepsis were top features determining the 30-day outcomes. A simple decision tree incorporating creatinine, INR and circulatory failure was able to classify patients into high (~90%), intermediate (~60%) and low risk (~20%) of mortality. A web-based AARC-AI model was developed and validated twice with optimal performance for 30-day predictions. CONCLUSIONS: The performance of the AARC-AI model exceeds the standard models for outcome predictions in ACLF. An AI-based decision tree can reliably undertake severity-based stratification of patients for timely interventions.

ABSTRACT

BACKGROUND AND STUDY AIMS: Weight reduction is the mainstay treatment for Nonalcoholic steatohepatitis (NASH). intragastric balloon (IGB) placement has proven benefit in terms of weight reduction. The aim of the present study is to assess the safety and efficacy of IGB placement in compensated NASH cirrhosis. PATIENTS AND METHODS: Nonalcoholic steatohepatitis cirrhosis patients with CTP ≤ 7, BMI of > 30, and who were unable to achieve weight reduction with lifestyle modification in past 3 months were prospectively enrolled. Spatz3™ adjustable gastric balloon was placed endoscopically. Primary objective was to determine efficacy in weight loss at 6 months, with secondary objectives of reduction in hepatic venous pressure gradient (HVPG), liver fat (controlled attenuation parameter, CAP), liver stiffness measurement (LSM) and clinical events as well as the tolerability and adverse events due to IGB placement. RESULTS: Altogether 56 cirrhosis patients, with a baseline BMI of 35.24 ± 3.92 and a CTP score of 6.27 ± 1.28 underwent IGB placement. The absolute weight reduction achieved was 15.88 kg (- 16.46%) and reduction in BMI was - 10.1% at 6 months. The percentage total body weight loss of ≥ 10% was achieved in 31 (55.35%) patients. The reduction in HVPG at 6-months was 11.12% (n = 16, 14.18 ± 2.12 to 12.60 ± 1.67 mmHg). The mean reduction in LSM was 28.6% and in CAP was 10.09%. Three (5.36%) patients required removal of IGB before 6-months due to persisting vomiting. No patient developed new-onset decompensation or any serious adverse event. CONCLUSION: IGB placement is a safe, well tolerated and effective option for reduction in weight and portal pressure in compensated obese cirrhosis patients.

ABSTRACT

AIM: To evaluate percutaneous transhepatic biliary interventions (PTBI) using the ADDFREE (Access-Drain-Dilate-Flush-REpeat periodically-Evaluate and remove) technique and its outcomes in patients with biliary enteric anastomotic strictures (BEAS) and hepatolithiasis. MATERIAL AND METHODS: A retrospective review was undertaken of patients having hepatolithiasis with BEAS who underwent PTBI with a therapeutic intent (from January 2010 to January 2021) was performed. The technical and clinical successes of PTBI were analysed. Technical success was divided into duct access, crossing of BEAS, stricture resolution, and calculi clearance. Improvement of liver function tests, resolution of leucocytosis and presenting complaints were considered as clinical success. The patients were followed-up for a minimum duration of 6-months. RESULTS: Eighteen patients received PTBI in form of the ADDFREE technique. Hepatolithiasis was bilobar (44.4%), unilobar in multiple ducts (unilobar-m; 27.8%) and unilobar in a single duct (unilobar-s; 27.8%) along with anastomotic stricture. The average number of sessions of stone clearance for bilobar, unilobar-m, and unilobar-s was 4.4 (±1.6), 3.6 (±2.4), and 1.5 (±0.5), respectively. Clinical success was observed in 14 (77.8%), while one patient had recurrence of calculi and received repeat treatment. Bile culture was positive for bacterial organisms in 17 (94.4%) patients. No major complication were seen while minor complication were seen in five patients consisting of self-limiting haemobilia (n=1), per-catheter bile leak (n=2) and aggravation of cholangitis (n=2). CONCLUSION: PTBI, consisting of bile duct access, cholangioplasty, and calculi clearance, is a safe and effective technique for the treatment of patients having hepatolithiasis secondary to BEAS.

ABSTRACT

The global burden of deaths caused by liver failure is substantial. The Asia-Pacific region is home to more than half of the global population and accounted for 62.6% of global deaths because of liver diseases in 2015. The aetiology of liver failure varies in different countries at different times. Viruses (Hepatitis A, B and E), drugs (herbs and anti-tuberculous drugs), toxins (alcohol use) and autoimmune flares are mainly responsible of majority of liver failure in individuals with normal liver (acute liver failure; ALF); else these may precipitate liver failure in those with chronic liver disease (acute-on-chronic liver failure; ACLF). Concomitant increases in alcohol misuse and metabolic syndrome in recent years are concerning. Ongoing efforts to address liver failure-related morbidity and mortality require accurate contemporary estimates of epidemiology and outcomes. In light of the ever-changing nature of liver disease epidemiology, accurate estimates for the burden of liver failure across the countries are vital for setting clinical, research and policy priorities. In this review, we aimed to describe the current as well as changing epidemiological trends of common liver failure syndromes, ALF and ACLF in the Asia-Pacific region.

ABSTRACT

BACKGROUND AND AIM: There is limited data on natural course and interventions in stage-3 acute kidney injury (AKI-3) in patients with acute-on-chronic liver failure (ACLF). We studied the factors of AKI-3 reversal and outcomes of dialysis in ACLF patients. METHODS: Consecutive patients with ACLF were prospectively enrolled (n = 1022) and variables determining AKI and its outcomes were analysed. RESULTS: At 1 month, 337 (33%) patients had AKI-3, of which, 131 had AKI-3 at enrolment and 206 developed AKI-3 during hospital stay. Of patients with AKI-3 at enrolment, 18% showed terlipressin response, 21% had AKI resolution and 59% required dialysis. High MELD (≥35) (model 1), serum bilirubin (≥23 mg/dL) (model 2) and AARC score (≥11) (model 3) were independent risk factors for dialysis. Dialysis was associated with worse survival in all AKI patients but improved outcomes in patients with AKI-3 (p = .022, HR 0.69 [0.50-0.95]). Post-mortem kidney biopsies (n = 61) revealed cholemic nephropathy (CN) in 54%, acute tubular necrosis (ATN) in 31%, and a combination (CN and ATN) in 15%. Serum bilirubin was significantly higher in patients with CN, CN and ATN compared with ATN respectively ([30.8 ± 12.2] vs. [26.7 ± 12.0] vs. [18.5 ± 9.8]; p = .002). CONCLUSION: AKI-3 rapidly increases from 13% to 33% within 30 days in ACLF patients. Histopathological data suggested cholemic nephropathy as the predominant cause which correlated with high bilirubin levels. AKI-3 resolves in only one in five patients. Patients with AARC grade 3 and MELD >35 demand need for early dialysis in AKI-3 for improved outcomes.

ABSTRACT

BACKGROUND AND AIMS: India has a significant burden of hepatitis C virus (HCV) infection and has committed to achieving national elimination by 2030. This will require a substantial scale-up in testing and treatment. The "HEAD-Start Project Delhi" aimed to enhance HCV diagnosis and treatment pathways among the general population. METHODS: A prospective study was conducted at 5 district hospitals (Arm 1: one-stop shop), 15 polyclinics (Arm 2: referral for viral load (VL) testing and treatment) and 62 screening camps (Arm 3: referral for treatment). HCV prevalence, retention in the HCV care cascade, and turn-around time were measured. RESULTS: Between January and September 2019, 37 425 participants were screened for HCV. The median (IQR) age of participants was 35 (26-48) years, with 50.4% male and 49.6% female. A significantly higher proportion of participants in Arm 1 (93.7%) and Arm 3 (90.3%) received a VL test compared with Arm 2 (52.5%, P < .001). Of those confirmed positive, treatment was initiated at significantly higher rates for participants in both Arms 1 (85.6%) and 2 (73.7%) compared to Arm 3 (41.8%, P < .001). Arm 1 was found to be a cost-saving strategy compared to Arm 2, Arm 3, and no action. CONCLUSIONS: Delivery of all services at a single site (district hospitals) resulted in a higher yield of HCV seropositive cases and retention compared with sites where participants were referred elsewhere for VL testing and/or treatment. The highest level of retention in the care cascade was also associated with the shortest turn-around times.

ABSTRACT

BACKGROUND AND AIMS: Clinically significant portal hypertension (CSPH), defined as hepatic venous pressure gradient (HVPG) ≥ 10 mmHg predicts clinical decompensation (CD) in cirrhosis. A proportion of cirrhosis patients have HVPG 6-10 mmHg. Their natural history is largely unknown. DESIGN: Consecutive patients with advanced chronic liver disease (aCLD) [histological cirrhosis(n = 196) or liver stiffness measurement (LSM) > 15 kPa(n = 65)] and HVPG 6-10 mmHg were included. Primary objective was to study their natural course and patterns of CD. We also analyzed the predictors of CD at presentation and on follow-up and response to carvedilol. RESULTS: Of 261 patients with HVPG 6-10 mmHg, 129(49.4%) had CD at first presentation; 78(29.9%) had single and 51(19.5%) had ≥ 2 CD. The most common CDs were ascites(n = 77) and jaundice(n = 65). A baseline HVPG ≥ 8 mmHg was independently associated with greater risk of CD [HR:1.7; p-0.002, AUROC:0.85(95%CI-0.81-0.91)]. New CD developed in 14.4% patients with compensated aCLD (median duration-23.1 months). Despite comparable baseline HVPG, patients developing new CD had higher HVPG on follow-up(15.3 ± 3.7 vs. 8 ± 2.1 mmHg; p < 0.001). Baseline LSM > 26.6 kPa, portosystemic shunt and serum albumin independently predicted new CD. Overall HVPG response to carvedilol(n = 60) was 23.3%, independent of baseline CD and HVPG. Five-year mortality was higher with ≥ 2 CD compared to single or no CD (23.5, 10 and 3%, respectively; p < 0.001). CONCLUSION: Nearly one-half of aCLD patients with HVPG 6-10 mmHg had CD, justifying the need to redefine CSPH. Interventions to reduce portal pressure in patients with HVPG ≥ 8 mmHg might improve long-term outcomes.

ABSTRACT

BACKGROUND AND AIMS: Feed intolerance (FI) is common in cirrhosis patients in intensive care units (ICU). Prokinetics are the first line treatment for FI but their efficacy and safety in critically ill patient with cirrhosis is unknown. We evaluated the role of prokinetics in reversal of FI and clinical outcomes. METHODS: Consecutive patients admitted in ICU developing new-onset FI, were randomized to receive either intravenous metoclopramide (Gr.A, n = 28), erythromycin (Gr.B, n = 27) or placebo (Gr.C, n = 28). FI was defined with the presence of 3 of 5 variables- absence of bowel sounds, gastric residual volume ≥ 500 ml, vomiting, diarrhoea and bowel distension. Primary end-point was complete resolution of FI (≥ 3 variables resolved) within 24-h and secondary end-points included resolution within 72-h and survival at 7-days. RESULTS: Of the 1030 ICU patients, 201 (19.5%) developed FI and 83 patients were randomized. Baseline parameters between the groups were comparable. Complete resolution at 24-h was higher in Gr.A (7.14%) and B (22.2%) than C (0%, p = 0.017). Overall, 58 (69.9%) patients achieved resolution within 72 h, more with metoclopramide (n = 24, 85.7%) and erythromycin (n = 25, 92.6%) than with placebo (n = 9, 32.1%, p < 0.001). The 7-day survival was better in patients who achieved resolution within 72-h (65.5 vs. 36%, p = 0.011) than non-responders. High lactate (OR-3.32, CI-1.45-7.70, p = 0.005), shock at baseline (OR-6.34, CI-1.67-24.1, p = 0.007) and resolution of FI within 72 h (OR-0.11, CI, 0.03-0.51, p = 0.04) predicted 7-day mortality. CONCLUSIONS: FI is common in critically-ill cirrhosis patients and non-resolution carries high mortality. Early recognition and treatment with prokinetics is recommended to improve short-term survival.


Gastrointestinal dysmotility is common in cirrhosis and higher incidence in critically ill patients. Promotility drugs are the first line of medication especially in ICU patients. In our study, we found that feed intolerance is present in nearly one in five critically ill cirrhosis and is associated with higher mortality. Patients who achieve resolution had an improved short-term survival. Prokinetic medications are safe in critically ill cirrhosis and help in early resolution of feed intolerance. Feed intolerance in critically ill cirrhosis should be recognized as an organ dysfunction and approaches for prevention and early diagnosis of feed intolerance could help in improving the outcomes in critical illness.

ABSTRACT

During the past two years, the redefinition of non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MAFLD) have been endorsed by international societies of hepatology, patient advocacy associations, and stakeholders. More recently, the American Association for the Study of Liver Diseases (AASLD) and the European Association for the Study of the Liver (EASL) have attempted to achieve a consensus. Three main fundamental issues raise concerns regarding the validity of the current consensus process. First, the development of the process and the selection of experts in the consensus panels remain unclear. Second, there is a concern regarding the quantity and quality of the evidence considered by the consensus panels. Third, there has been a lack of input to the consensus panel decisions from the academic and clinical community. This Editorial aims to raise an urgent note of caution regarding the consensus process used by the AASLD and EASL regarding fatty liver disease, to prevent world divide and different global definitions and guidelines from being adopted.

ABSTRACT

BACKGROUND: Role of Convalescent plasma (COPLA) to treat severe COVID-19 is under investigation. We compared efficacy and safety of COPLA with fresh frozen plasma (FFP) in severe COVID-19 patients. METHODS: One group received COPLA with standard medical care (n = 14), and another group received random donor FFP, as control with standard medical care (n = 15) in severe COVID-19 disease. RESULTS: The proportion of patients free of ventilation at day seven were 78.5% in COPLA group, and 93.3 % in control group were not significant (p= 0.258). However, improved respiratory rate, O2 saturation, SOFA score, and Ct value were observed in the COPLA group. No serious adverse events were noticed by plasma transfusion in both groups.

ABSTRACT

Liver failure in the context of acute (ALF) and acute on chronic liver failure (ACLF) is associated with high mortality in the absence of a liver transplant. For decades, therapeutic plasma exchange (TPE) is performed for the management of immune-mediated diseases. TPE has emerged as an attractive extracorporeal blood purification technique in patients with ALF and ACLF. The basic premise of using TPE is to remove the toxic substances which would allow recovery of native liver functions by facilitating liver regeneration. In recent years, encouraging data have emerged, suggesting the benefits of TPE in patients with liver failure. TPE has emerged as an attractive liver support device for the failing liver until liver transplantation or clinical recovery. The data in patients with ALF suggest routine use of high-volume TPE, while the data for such a strategy are less robust for patients with ACLF.

ABSTRACT

Patients with decompensated cirrhosis are currently managed through targeted strategies aimed at preventing or treating specific complications. In contrast, a disease-modifying agent should, by definition, be aimed at globally addressing 'decompensated cirrhosis'. To be defined as a disease-modifying agent in decompensated cirrhosis, interventions need to demonstrate an unequivocal benefit on the course of disease in well-designed and adequately powered randomised clinical trials with hard endpoints (i.e. patient survival). These trials also need to define the target population, dosage and timing of administration, factors guiding treatment, temporary or permanent stopping rules, transferability to daily clinical practice, cost-effectiveness, and global treatment access. By eliminating the underlying cause of cirrhosis, aetiologic treatments can still influence the course of decompensated disease by halting or slowing down disease progression or even inducing reversion to the compensated state. In contrast, there remains an unmet clinical need for disease-modifying agents which can antagonise key pathophysiological mechanisms of decompensated cirrhosis, such as portal hypertension, gut translocation, circulatory dysfunction, systemic inflammation, and immunological dysfunction. However, in the last few years, the repurposing of "old drugs" that have already been prescribed for more limited indications in hepatology or for other diseases has provided a few candidates, including human albumin, statins, and poorly absorbable oral antibiotics, which are under further evaluation in large-scale randomised clinical trials. New disease-modifying agents are also expected to be identified in the next decade through the systematic repurposing of existing drugs and the development of novel molecules which are currently undergoing pre-clinical or early clinical testing.

ABSTRACT

BACKGROUND & AIMS: Corticosteroids are the only effective therapy for severe alcohol-associated hepatitis (AH), defined by a model for end-stage liver disease (MELD) score >20. However, there are patients who may be too sick to benefit from therapy. Herein, we aimed to identify the range of MELD scores within which steroids are effective for AH. METHODS: We performed a retrospective, international multicenter cohort study across 4 continents, including 3,380 adults with a clinical and/or histological diagnosis of AH. The main outcome was mortality at 30 days. We used a discrete-time survival analysis model, and MELD cut-offs were established using the transform-the-endpoints method. RESULTS: In our cohort, median age was 49 (40-56) years, 76.5% were male, and 79% had underlying cirrhosis. Median MELD at admission was 24 (19-29). Survival was 88% (87-89) at 30 days, 77% (76-78) at 90 days, and 72% (72-74) at 180 days. A total of 1,225 patients received corticosteroids. In an adjusted-survival-model, corticosteroid use decreased 30-day mortality by 41% (hazard ratio [HR] 0.59; 0.47-0.74; p <0.001). Steroids only improved survival in patients with MELD scores between 21 (HR 0.61; 0.39-0.95; p = 0.027) and 51 (HR 0.72; 0.52-0.99; p = 0.041). The maximum effect of corticosteroid treatment (21-30% survival benefit) was observed with MELD scores between 25 (HR 0.58; 0.42-0.77; p <0.001) and 39 (HR 0.57; 0.41-0.79; p <0.001). No corticosteroid benefit was seen in patients with MELD >51. The type of corticosteroids used (prednisone, prednisolone, or methylprednisolone) was not associated with survival benefit (p = 0.247). CONCLUSION: Corticosteroids improve 30-day survival only among patients with severe AH, especially with MELD scores between 25 and 39. LAY SUMMARY: Alcohol-associated hepatitis is a condition where the liver is severely inflamed as a result of excess alcohol use. It is associated with high mortality and it is not clear whether the most commonly used treatments (corticosteroids) are effective, particularly in patients with very severe liver disease. In this worldwide study, the use of corticosteroids was associated with increased 30-day, but not 90- or 180-day, survival. The maximal benefit was observed in patients with an MELD score (a marker of severity of liver disease; higher scores signify worse disease) between 25-39. However, this benefit was lost in patients with the most severe liver disease (MELD score higher than 51).
