Abstract
INTRODUCTION Human albumin is used in the treatment of complications of cirrhosis. However, the use of long-term human albumin administration is costly and resource demanding for both patients and healthcare systems. A precision medicine approach with biomarkers to predict human albumin treatment response, so-called predictive biomarkers, could make this a viable treatment option in patients with cirrhosis and ascites. METHODS AND ANALYSIS ALB-TRIAL is a multinational, double-blind, placebo-controlled randomised controlled trial. We aim to validate a predictive biomarker, consisting of a panel of circulating metabolites, to predict the treatment response to human albumin in patients with cirrhosis and ascites. All enrolled patients are stratified into a high-expected or low-expected effect stratum of human albumin based on the biomarker outcome. After stratification, patients in each group are randomised into either active treatment (20% human albumin) or corresponding placebo (0.9% NaCl) every 10th day for 6 months. The primary outcome is the cumulative number of liver-related events (composite of decompensation episodes, transjugular intrahepatic shunt insertion, liver transplantation and death). Key secondary outcomes include time-to-event analysis of primary outcome components, an analysis of the total healthcare burden and a health economic analysis. ETHICS AND DISSEMINATION The trial obtained ethical and regulatory approval in Denmark, Germany, the Netherlands, Belgium, Hungary and Spain through the Clinical Trials Information System (CTIS) from 13 February 2023, while UK approvals from the Health Regulatory Authority, Medicines and Healthcare products Regulatory Agency and Research Ethics Committee are pending. Findings will be published in peer-reviewed journals, presented at conferences, communicated to relevant stakeholders and in the public registry of CTIS, following trial completion. TRIAL REGISTRATION NUMBER NCT05056220 EU CT 2022-501006-34-01.

Abstract
INTRODUCTION AND OBJECTIVES Clinical data for older patients with advanced liver disease are limited. This post hoc analysis evaluated the efficacy and safety of terlipressin in patients aged ≥65 years with hepatorenal syndrome using data from 3 Phase III, randomized, placebo-controlled studies (OT-0401, REVERSE, CONFIRM). PATIENTS AND METHODS The pooled population of patients aged ≥65 years (terlipressin, n = 54; placebo, n = 36) was evaluated for hepatorenal syndrome reversal-defined as a serum creatinine level ≤1.5 mg/dL (≤132.6 μmol/L) while receiving terlipressin or placebo, without renal replacement therapy, liver transplantation, or death-and the incidence of renal replacement therapy (RRT). Safety analyses included an assessment of adverse events. RESULTS Hepatorenal syndrome reversal was almost 2-times higher in terlipressin-treated patients compared with patients who received placebo (31.5% vs 16.7%; P = 0.143). Among surviving patients, the need for RRT was significantly reduced in the terlipressin group, with an almost 3-times lower incidence of RRT versus the placebo group (Day 90: 25.0% vs 70.6%; P = 0.005). Among 23 liver-transplant-listed patients, significantly fewer patients in the terlipressin versus placebo group needed RRT by Days 30 and 60 (P = 0.027 each). Fewer patients in the terlipressin group needed RRT post-transplant (P = 0.011). More terlipressin-treated patients who were listed for and received a liver transplant were alive and RRT-free by Day 90. No new safety signals were revealed in the older subpopulation compared with previously published data. CONCLUSIONS Terlipressin therapy may lead to clinical improvements in highly vulnerable patients aged ≥65 years with hepatorenal syndrome.

Abstract
BACKGROUND The efficacy of targeted albumin therapy in the management of decompensatory events in cirrhosis is unclear with different reports showing conflicting results. It is possible that only certain subgroups of patients may benefit from targeted albumin administration. However, extensive conventional subgroup analyses have not yet identified these subgroups. Albumin is an important regulator of physiological networks and may interact with homeostatic mechanism differently in patients according to the integrity of their physiological network. In the present study we aimed to assess the value of network mapping in predicting response to targeted albumin therapy in patients with cirrhosis. METHOD This is a sub-study of the ATTIRE trial; a multicentre, randomized trial conducted to assess the effect of targeted albumin therapy in cirrhosis. Baseline serum bilirubin, albumin, sodium, creatinine, CRP, and white cell count (WCC), international normalised ratio, heart rate, and blood pressure of 777 patients followed up for 6 months were used for network mapping using parenclitic analysis. Parenclitic network analysis involves measuring the deviation of each individual patient from the existing network of physiological interactions in a reference population. RESULT Overall network connectivity as well as deviations along WCC-CRP axis predicted 6-month survival independent of age and model for end-stage liver disease (MELD) in the standard care arm. Patients with lower deviation along the WCC-CRP axis showed lower survival in response to targeted albumin administration over 6-month follow-up period. Likewise, patients with higher overall physiological connectivity survived significantly less than the standard care group following targeted albumin infusion. CONCLUSION The parenclitic network mapping can predict survival of patients with cirrhosis and identify patient subgroups that don't benefit from targeted albumin therapy.

Hepatology International. 2023;17(1):180-189
Abstract
PURPOSE Probing efficacy and safety of lusutrombopag in Chinese chronic liver disease (CLD) and severe thrombocytopenia (PLT < 50 × 10(9)/L) patients undergoing elective invasive procedures. METHODS In this double-blind, parallel-group phase 3 study, 66 patients with CLD and severe thrombocytopenia were randomized 2:1 to lusutrombopag or placebo arm treatment regimens for seven days at 9 centers in China. Responders (PLT ≥ 50 × 10(9)/L that increased to ≥ 20 × 10(9)/L from the baseline and not received rescue therapy for bleeding) on Day 8 (the day after seven-day treatment) were assessed. PLT ≥ 50 × 10(9)/L on or after Day 8 and within 2 days before invasive procedure (alternative criteria for not requiring platelet transfusion) were also analyzed. Adverse events (AEs) were recorded. RESULTS The proportion of responders on Day 8 was evidently higher (p = 0.0011) in the lusutrombopag group (43.2%, 19/44) versus placebo (4.5%, 1/22). And 72.7% (32/44) patients receiving lusutrombopag met the alternative criteria for not requiring platelet transfusion, while 18.2% (4/22) in the placebo group. The median maximum PLT in lusutrombopag group increased to 80.5 × 10(9)/L, and median time to reach maximum was 14.5 days. Compared with placebo, the lusutrombopag group had a lower incidence of bleeding events (6.8% versus 13.6%), and only one patient had thrombotic-related AE. Overall, the incidence of treatment-emergent AEs was comparable between two groups. CONCLUSIONS Lusutrombopag was effective in raising PLT, diminishing platelet transfusion requirement, and documented a safety profile like the placebo in CLD and severe thrombocytopenia patients in a Chinese cohort undergoing elective invasive procedures.

Indian journal of pharmacology. 2023;55(1):21-26
Abstract
OBJECTIVE The objective of the study was to compare and observe the therapeutic effect of octreotide and pituitrin in upper gastrointestinal hemorrhage caused by cirrhosis. MATERIALS AND METHODS In this prospective, randomized, open, single-blind, controlled, and single-center study, patients with upper gastrointestinal hemorrhage induced by cirrhosis were divided into control group (treated with pituitrin) and experimental group (treated with octreotide). The effective time, hemostasis time, and average bleeding volume of the two groups were observed and recorded, and the incidence of adverse reactions, rebleeding rate, and total effective rate of the two groups were compared. RESULTS One hundred and thirty-two patients with upper gastrointestinal hemorrhage caused by cirrhosis were included from March 2017 to September 2018. By a single-blind method, the patients were randomly divided into control group (n = 66) and experimental group (n = 66). Compared with the control group, the effective time and hemostasis time of the drug were significantly shorter in the experimental group, whereas the average bleeding volume of patients was lower (average P < 0.05). Compare with the control group, the total effective rate was higher in the experimental group, whereas the incidence of adverse reactions was lower (average P < 0.05). During 1-year follow-up, early and late rebleeding rates and hemorrhage-related mortality between the two groups have no difference (average P > 0.05). CONCLUSION In the treatment of upper gastrointestinal hemorrhage in cirrhosis, octreotide is superior to pituitrin, with advantages of quick onset, short hemostasis time, and less adverse reactions, which is helpful to control the rebleeding rate and bleeding-related mortality.

Therapeutic advances in gastroenterology. 2022;15:17562848221105976
Abstract
INTRODUCTION Few data have been published on the ethnic sensitivity of effectiveness, pharmacokinetics (PK), and pharmacodynamics (PD) of avatrombopag for the management of thrombocytopenia in patients with chronic liver disease (CLD). METHODS An ethnic sensitivity analysis was performed based on the results from two phase III studies (ADAPT-1 and ADAPT-2), with a primary endpoint of the proportion of patients without the requirement of platelet transfusion or rescue treatment for bleeding after randomization to 7 days following a scheduled procedure, and three phase I studies in healthy subjects. Cochran-Mantel-Haenszel and Fisher's exact tests were used to compare the differences in effectiveness in different ethnicities and overall population. RESULTS In total, 435 patients (placebo, n = 158; avatrombopag, n = 277) were stratified into various ethnic groups: 121 East Asians, including the subgroup of 27 Chinese, and 259 Caucasians. The proportion of patients who did not receive a platelet transfusion and those with a platelet count ⩾50 × 10(9)/L in the avatrombopag 40 and 60 mg groups were higher than that of placebo for all ethnicities and in the overall population. Statistical significance was obtained in the overall population and for all ethnicities other than Chinese patients, a group with a very small sample size. No significant difference was observed in the proportion of responders in each ethnic group compared to overall population (p > 0.05). The incidence of adverse events in East Asians was similar to that in both Caucasians and the overall population. CONCLUSION Avatrombopag was effective and safe in the management of thrombocytopenia in Chinese patients with CLD. Ethnicity does not appear to influence the efficacy, safety, PK, or PD of avatrombopag.

Gubensek J, Andonova M, Jerman A, Persic V, Vajdic-Trampuz B, Zupunski-Cede A, Sever N, Plut S
Frontiers in medicine. 2022;9:870067
Abstract
BACKGROUND AND AIMS Both insulin and plasma exchange (PE) are used in hypertriglyceridemic acute pancreatitis (HTG-AP). Our aim was to compare the efficacy of both treatments. METHODS A randomized, parallel group study performed in a tertiary hospital in 22 HTG-AP patients with non-severe prognosis and triglycerides between 15 and 40 mmol/L. Patients were randomized to daily PE or insulin infusion until triglycerides were <10 mmol/L. Primary outcome was % reduction in triglycerides within 24 h. Secondary outcomes were days needed to lower triglycerides <10 mmol/L, highest CRP and percentage of patients with a severe course of pancreatitis. RESULTS There was a trend toward a greater decrease in triglycerides within the first 24 h in the PE group (67 ± 17% vs. 53 ± 17%, p = 0.07), but the absolute difference was modest [mean difference of 6 mmol/L (14% of initial value)]. Triglycerides fell below 10 mmol/L in a median (IQR) of 1 (1-2) and 2 (1-2) days, respectively (p = 0.25). Secondary outcomes related to disease severity were also comparable: highest CRP 229 vs. 211 mg/L (p = 0.69) and severe course of pancreatitis in 2/11 cases in both groups (p = 1.0). Regarding treatment complications, there was one mild hypoglycemia and one allergic reaction during PE. Survival was 100% in both groups. CONCLUSION There was no significant difference, but only a trend toward a greater decrease in triglycerides with PE, and the clinical course was also comparable. These results do not support universal use of PE in patients with HTG-AP. CLINICAL TRIAL REGISTRATION [ClinicalTrials.gov], identifier [NCT02622854].

Timing of endoscopic intervention in patients with cirrhosis with acute variceal haemorrhage (TEACH trial): protocol for a randomised clinical trial (RCT)
Yang, Z., Xuan, J., Yang, F., Qi, Y., Yang, M., Xu, H., Jiang, M., Shen, S., Lu, M., Shi, H., et al
BMJ open. 2022;12(9):e060290
Abstract
INTRODUCTION Acute variceal haemorrhage (AVH) in patients with cirrhosis remains a topic of great interest. Although several guidelines recommend endoscopy within 24 hours after AVH, there is no consensus on the most appropriate time to perform this intervention. The purpose of this study is to identify whether urgent endoscopy (within 6 hours after gastroenterological consultation) is superior to non-urgent endoscopy (between 6 hours and 24 hours after gastroenterological consultation) in reducing the rebleeding rate of these patients. METHODS AND ANALYSIS This is a single-centred, prospective, randomised clinical trial. Between March 2021 and December 2023, an estimated 400 patients will be randomised in a 1:1 ratio to receive endoscopic intervention either within 6 hours or between 6 and 24 hours after gastroenterological consultation. Randomisation will be conducted by permuted block randomisation, with stratification by age, systolic blood pressure and pulse rate. The primary efficacy endpoint is rebleeding within 42 days after control of AVH. The secondary efficacy endpoints mainly include all-cause mortality within 42 days after randomisation, persistent bleeding, length of hospitalisation, etc. ETHICS AND DISSEMINATION The study protocol was approved by the Ethical Committees of Jinling Hospital (authorised ethics no. DZQH-KYLL-21-01). This trial will provide valuable insights into the timing of endoscopic intervention for AVH in patients with cirrhosis. Furthermore, the trial results and conclusions could provide high-quality evidence to guide clinical research and treatment. TRIAL REGISTRATION NUMBER NCT04786743.

Du L, Ma Y, Zhou S, Chen F, Xu Y, Wang M, Lei X, Feng P, Tang H, Bai L
Scientific reports. 2021;11(1):1469
Abstract
Artificial liver support system (ALSS) therapy is widely used in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). We aimed to develop a predictive score to identify the subgroups who may benefit from plasma exchange (PE)-centered ALSS therapy. A total of 601 patients were retrospectively enrolled and randomly divided into a derivation cohort of 303 patients and a validation cohort of 298 patients for logistic regression analysis, respectively. Five baseline variables, including liver cirrhosis, total bilirubin, international normalized ratio of prothrombin time, infection and hepatic encephalopathy, were found independently associated with 3-month mortality. A predictive PALS model and the simplified PALS score were developed. The predicative value of PALS score (AUROC = 0.818) to 3-month prognosis was as capable as PALS model (AUROC = 0.839), R score (AUROC = 0.824) and Yue-Meng' score (AUROC = 0.810) (all p > 0.05), and superior to CART model (AUROC = 0.760) and MELD score (AUROC = 0.765) (all p < 0.05). The PALS score had significant linear correlation with 3-month mortality (R(2) = 0.970, p = 0.000). PALS score of 0-2 had both sensitivity and negative predictive value of > 90% for 3-month mortality, while PALS score of 6-9 had both specificity and positive predictive value of > 90%. Patients with PALS score of 3-5 who received 3-5 sessions of ALSS therapy had much lower 3-month mortality than those who received 1-2 sessions (32.8% vs. 59.2%, p < 0.05). The more severe patients with PALS score of 6-9 could still benefit from ≥ 6 sessions of ALSS therapy compared to ≤ 2 sessions (63.6% vs. 97.0%, p < 0.05). The PALS score could predict prognosis reliably and conveniently. It could identify the subgroups who could benefit from PE-centered ALSS therapy, and suggest the reasonable sessions.Trial registration: Chinese Clinical Trial Registry, ChiCTR2000032055.

Evidence-based complementary and alternative medicine : eCAM. 2021;2021:6548479
Abstract
OBJECTIVE Liver cirrhosis is a common, often progressive, and usually fatal disorder. Upper gastrointestinal bleeding is a leading cause of death in patients with liver cirrhosis. The purpose of this study was to evaluate the effectiveness of somatostatin combined with restricted fluid resuscitation in the treatment of upper gastrointestinal bleeding in the patients with liver cirrhosis. METHODS From January 2018 to December 2020, 84 patients with liver cirrhosis complicated by upper gastrointestinal bleeding admitted to the Department of Gastroenterology of Ningbo Yinzhou No. 2 Hospital were selected as study participants. They were randomly assigned into the study group (n = 42) and control group (n = 42). All patients were given intravenous drip of somatostatin. The study group was supplemented with restricted fluid resuscitation therapy. The hemoglobin (Hb), platelet, fibrinogen, hematocrit, transfusion volume of red blood cells, hemostatic time, hemostatic rates in 0 h-24 h, 24 h-48 h, and >48 h, rebleeding rates, resuscitation rate, and incidence rates of complications were compared between the two groups 48 h after treatment. RESULTS It was found that the Hb, platelet, fibrinogen, and hematocrit were notably increased in the study group compared to the control group 48 h after treatment (P < 0.01). The proportion of patients with excellent response was notably higher in the study group than in the control group (P < 0.05). The overall response rate of the study group was 90.48%, which was significantly higher than 71.43% in the control group (P < 0.05). The study group had lower transfusion volume of red blood cells, shorter hemostatic time, and lower rebleeding rates than the control group (P < 0.01). The hemostatic rate of 0 h-24 h in the study group was remarkably higher than that in the control group (P < 0.05). The hemostatic rate of >48 h in the study group was lower than that in the control group (P < 0.05). The overall incidence rate of complications in the study group was 9.52%, which was significantly lower than 30.95% in the control group (P < 0.05). CONCLUSION These data suggest that intravenous drip of somatostatin followed by restricted fluid resuscitation leads to a better clinical efficacy in treating upper gastrointestinal bleeding in patients with liver cirrhosis considering higher resuscitation rate and hemostatic rate and reduced incidence of complications, which is conducive to the recovery of patients and worthy of further clinical promotion.
