Abstract
BACKGROUND High volume plasma-exchange (HVPE) improves survival in patients with acute liver failure (ALF), but apprehension regarding volume overload and worsening of cerebral edema remain. METHODS In an open-label randomized controlled trial, 40 consecutive patients of ALF were randomized 1:1 to either standard medical treatment (SMT) or SMT with standard-volume plasma-exchange (SVPE). SVPE was performed using centrifugal apheresis [target volume of 1.5 to 2.0 plasma volumes per session] until desired response was achieved. Cerebral edema was assessed by brain imaging. Results were analyzed in an intention-to-treat analysis. Primary outcome was 21-day transplant-free survival. The levels of cytokines, damage-associated molecular patterns (DAMPs) and endotoxins were analyzed at baseline and day 5. RESULTS ALF patients [aged 31.5 ± 12.2 years, 60% male, 78% viral, 83% hyperacute, 70% with SIRS were included. At day 5, SVPE [mean sessions 2.15 ± 1.42, median plasma volume replaced 5.049 L] compared to SMT alone, resulted in higher lactate clearance (p = .02), amelioration of SIRS (84% vs. 26%; P = .02), reduction in ammonia levels [(221.5 ± 96.9) vs.(439 ± 385.6) μg/dl, P = .02) and SOFA scores [9.9(±3.3) vs. 14.6(±4.8); P = .001]. There were no treatment related deaths. SVPE was associated with a higher 21-day transplant free-survival [75% vs. 45%; P = .04, HR 0.30, 95%CI 0.01-0.88]. A significant decrease in levels of pro-inflammatory cytokines and an increase in anti-inflammatory cytokines along with a decrease in endotoxin and DAMPs was seen with SVPE. CONCLUSION In ALF patients with cerebral edema, SVPE is safe and effective and improves survival possibly by a reduction in cytokine storm and ammonia. CLINICALTRIAL gov (identifier: NCT02718079).
PICO Summary
Population
Patients with acute liver failure (n= 40).
Intervention
Standard medical treatment with standard volume plasma exchange (SVPE), (n= 20).
Comparison
Standard medical treatment (n= 20).
Outcome
Compared to standard medical treatment alone, at day five SVPE resulted in higher lactate clearance, amelioration of systemic inflammatory response syndrome (84% vs. 26%), reduction in ammonia levels [(221.5 ± 96.9) vs. (439 ± 385.6) μg/dl] and sequential organ failure assessment scores [9.9(±3.3) vs. 14.6(±4.8)].

Eguchi Y, Takahashi H, Mappa S, Santagostino E
Hepatology research : the official journal of the Japan Society of Hepatology. 2022
Abstract
AIM: Avatrombopag, a thrombopoietin receptor agonist, can reduce the need for platelet transfusions or rescue interventions for bleeding in patients with chronic liver disease (CLD) and thrombocytopenia undergoing scheduled procedures. A model analysis indicated that the effect of avatrombopag on platelet production was reduced in East Asian versus non-East Asian patients; however, the difference was deemed not clinically significant. Furthermore, a subgroup analysis of pooled Phase 3 trials showed similar avatrombopag efficacy across racial subgroups. The aim of this Phase 2 study was to corroborate the efficacy and safety of avatrombopag in Japanese patients with thrombocytopenia due to CLD. METHODS Japanese patients with CLD and thrombocytopenia were randomized to receive placebo or avatrombopag 20, 40, or 60 mg daily for 5 days. The primary endpoint was responder rate in platelet counts at Visit 4 (10-13 days after treatment initiation), defined as the proportion of patients with platelet count ≥50×10(9) /L and ≥20×10(9) /L increase from baseline. RESULTS Thirty-nine patients were randomized and completed the study (placebo, n=11; avatrombopag 20 mg, n=7; 40 mg, n=11; 60 mg, n=10). Avatrombopag treatment was associated with significant increases in responder rate at Visit 4 in the 40 mg (63.6%; P=0.004) and 60 mg (40%; P=0.024) groups versus placebo (9.1%). Avatrombopag was well tolerated and no new safety signals were detected. CONCLUSIONS Efficacy and safety results from this study were consistent with previous studies in patients with CLD and thrombocytopenia undergoing elective procedures, supporting treatment with avatrombopag in the Japanese population.

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].

Abstract
BACKGROUND Plasma is frequently administered to patients with prolonged INR prior to invasive procedures. However, there is limited evidence evaluating efficacy and safety. STUDY DESIGN AND METHODS We performed a pilot trial in hospitalized patients with INR between 1.5 and 2.5 undergoing procedures conducted outside the operating room. We excluded patients undergoing procedures proximal to the central nervous system, platelet counts <40,000/μl, or congenital or acquired coagulation disorders unresponsive to plasma. We randomly allocated patients stratified by hospital and history of cirrhosis to receive plasma transfusion (10-15 cc/kg) or no transfusion. The primary outcome was change in hemoglobin concentration within 2 days of procedure. RESULTS We enrolled 57 patients, mean age 56.0, 34 (59.6%) with cirrhosis, and mean INR 1.92 (SD = 0.27). In the intention to treat analysis, there were 10 of 27 (38.5%) participants in the plasma arm with a post procedure INR <1.5 and one of 30 (3.6%) in the no treatment arm (p < .01). The mean INR after receiving plasma transfusion was -0.24 (SD 0.26) lower than baseline. The change from pre-procedure hemoglobin level to lowest level within 2 days was -0.6 (SD = 1.0) in the plasma transfusion arm and -0.4 (SD = 0.6) in the no transfusion arm (p = .29). Adverse outcomes were uncommon. DISCUSSION We found no differences in change in hemoglobin concentration in those treated with plasma compared to no treatment. The change in INR was small and corrected to less than 1.5 in minority of patients. Large trials are required to establish if plasma is safe and efficacious.

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.

Hepatology (Baltimore, Md.). 2021
Abstract
The optimal treatment for gastric varices (GVs) has not yet been fully determined. This study compared the efficacy and safety of endoscopic cyanoacrylate injection and balloon-occluded retrograde transvenous obliteration (BRTO) to prevent rebleeding in patients with cirrhosis and GVs after primary hemostasis. Patients with cirrhosis and history of bleeding from gastroesophageal varices type 2 or isolated gastric varices type 1 were randomized to cyanoacrylate injection (n = 32) or BRTO treatment (n = 32). The primary outcomes were gastric variceal rebleeding or all-cause rebleeding. The patient characteristics were well-balanced between two groups. The mean follow-up time was 27.1 ± 12 months in a cyanoacrylate injection group and 27.6 ± 14.3 months in a BRTO group. The probability of gastric variceal rebleeding was higher in the cyanoacrylate injection group than in the BRTO group (p = 0.024). The probability of remaining free of all-cause rebleeding at 1 and 2 years for cyanoacrylate injection vs BRTO was 77% vs 96.3% and 65.2% vs 92.6% (p = 0.004). The survival rates, frequency of complications, and worsening of EVs were similar in both groups. BRTO resulted in fewer hospitalizations, inpatient stays, and lower medical costs. CONCLUSIONS BRTO is more effective than cyanoacrylate injection in preventing rebleeding from GVs, with similar frequencies of complications and mortalities.

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.

Li B, Chen J, Zhang CQ, Wang GC, Hu JH, Luo JJ, Zhang W, Wei YC, Zeng XQ, Chen SY
Annals of translational medicine. 2021;9(9):793
Abstract
BACKGROUND Vasoactive drugs can reduce portal venous pressure and control variceal bleeding. However, few studies have explored the hemodynamic effects of terlipressin and high-dose octreotide in such patients. Our purpose was to evaluate the hemodynamic changes and safety of using terlipressin and high-dose octreotide in patients with decompensated liver cirrhosis. METHODS A multi-center randomized controlled trial was conducted. Cirrhotic patients with a history of variceal bleeding were included. Terlipressin or high-dose octreotide was administered during the procedure of measuring hepatic venous pressure gradient (HVPG). Hemodynamic parameters and symptoms were recorded. RESULTS A total of 88 patients were included. HVPG was significantly reduced at 10, 20, and 30 min after drug administration in the terlipressin group (16.3±6.4 vs. 14.7±5.9, 14.0±6.1, and 13.8±6.1, respectively, P<0.001) and the high-dose octreotide group (17.4±6.6 vs. 15.1±5.8, 15.3±6.2, and 16.1±6.0, respectively P<0.01). Decreased heart rate and increased mean arterial pressure were more often observed in the terlipressin group. The overall response rates were not significantly different between the groups (52.8% vs. 44.8%, P=0.524). The terlipressin group had significantly higher response rates at 30 min compared to the high-dose octreotide group in those with alcoholic liver cirrhosis [6/6 (100%) vs. 0/4 (0%), P=0.005]. The incidence of adverse drug events was rare and similar in the two groups. CONCLUSIONS Both terlipressin and high-dose octreotide were effective and safe for reducing HVPG. The pharmacodynamic effect of terlipressin persisted longer. The terlipressin group had higher response rates in those with alcoholic cirrhosis (trial number: NCT02119884).

Abstract
BACKGROUND Infection and increased systemic inflammation cause organ dysfunction and death in patients with decompensated cirrhosis. Preclinical studies provide support for an antiinflammatory role of albumin, but confirmatory large-scale clinical trials are lacking. Whether targeting a serum albumin level of 30 g per liter or greater in these patients with repeated daily infusions of 20% human albumin solution, as compared with standard care, would reduce the incidences of infection, kidney dysfunction, and death is unknown. METHODS We conducted a randomized, multicenter, open-label, parallel-group trial involving hospitalized patients with decompensated cirrhosis who had a serum albumin level of less than 30 g per liter at enrollment. Patients were randomly assigned to receive either targeted 20% human albumin solution for up to 14 days or until discharge, whichever came first, or standard care. Treatment commenced within 3 days after admission. The composite primary end point was new infection, kidney dysfunction, or death between days 3 and 15 after the initiation of treatment. RESULTS A total of 777 patients underwent randomization, and alcohol was reported to be a cause of cirrhosis in most of these patients. A median total infusion of albumin of 200 g (interquartile range, 140 to 280) per patient was administered to the targeted albumin group (increasing the albumin level to ≥30 g per liter), as compared with a median of 20 g (interquartile range, 0 to 120) per patient administered to the standard-care group (adjusted mean difference, 143 g; 95% confidence interval [CI], 127 to 158.2). The percentage of patients with a primary end-point event did not differ significantly between the targeted albumin group (113 of 380 patients [29.7%]) and the standard-care group (120 of 397 patients [30.2%]) (adjusted odds ratio, 0.98; 95% CI, 0.71 to 1.33; P = 0.87). A time-to-event analysis in which data were censored at the time of discharge or at day 15 also showed no significant between-group difference (hazard ratio, 1.04; 95% CI, 0.81 to 1.35). More severe or life-threatening serious adverse events occurred in the albumin group than in the standard-care group. CONCLUSIONS In patients hospitalized with decompensated cirrhosis, albumin infusions to increase the albumin level to a target of 30 g per liter or more was not more beneficial than the current standard care in the United Kingdom.

Targeted Albumin Therapy Does Not Improve Short-Term Outcome in Hyponatremic Patients Hospitalized With Complications of Cirrhosis: Data From the ATTIRE Trial
China L, Freemantle N, Forrest E, Kallis Y, Ryder SD, Wright G, O'Brien A
The American journal of gastroenterology. 2021
Abstract
INTRODUCTION Patients with decompensated cirrhosis and hyponatremia have a poor prognosis. We investigated Albumin to Prevent Infection in Chronic Liver Failure trial data to determine whether targeted albumin infusions improved outcome in patients with hyponatremia at baseline. METHODS We examined the interaction between targeted albumin and standard care for the composite primary end point, stratifying by baseline sodium ≥ and <130 mmol/L. RESULTS Randomization to albumin was associated with a significant increase in sodium; however, there was no interaction between sodium category and treatment for the trial primary end point. DISCUSSION Targeted intravenous albumin infusions increased serum sodium level in hospitalized hyponatremic patients with cirrhosis, but this did not improve outcome.
