Systematic review: The model for end-stage liver disease--should it replace Child-Pugh's classification for assessing prognosis in cirrhosis?

Visualizing global progress and challenges in esophagogastric variceal bleeding

BACKGROUND

Esophageal and gastric variceal bleeding is a catastrophic complication of portal hypertension, most commonly caused by cirrhosis of various etiologies. Although a considerable body of research has been conducted in this area, the complexity of the disease and the lack of standardized treatment strategies have led to fragmented findings, insufficient information, and a lack of systematic investigation. Bibliometric analysis can help clarify research trends, identify core topics, and reveal potential future directions. Therefore, this study aims to use bibliometric methods to conduct an in-depth exploration of research progress in this field, with the expectation of providing new insights for both clinical practice and scientific research.

AIM

To evaluate research trends and advancements in esophagogastric variceal bleeding (EGVB) over the past twenty years.

METHODS

Relevant publications on EGVB were retrieved from the Web of Science Core Collection. VOSviewer, Pajek, CiteSpace, and the bibliometrix package were then employed to perform bibliometric visualizations of publication volume, countries, institutions, journals, authors, keywords, and citation counts.

RESULTS

The analysis focused on original research articles and review papers. From 2004 to 2023, a total of 2097 records on EGVB were retrieved. The number of relevant publications has increased significantly over the past two decades, especially in China and the United States. The leading contributors in this field, in terms of countries, institutions, authors, and journals, were China, Assistance Publique-Hôpitaux de Paris, Bosch Jaime, and World Journal of Gastroenterology, respectively. Core keywords in this field include portal hypertension, management, liver cirrhosis, risk, prevention, and diagnosis. Future research directions may focus on optimizing diagnostic methods, personalized treatment, and multidisciplinary collaboration.

CONCLUSION

Using bibliometric methods, this study reveals the developmental trajectory and trends in research on EGVB, underscoring risk assessment and diagnostic optimization as the core areas of current focus. The study provides an innovative and systematic perspective for this field, indicating that future research could center on multidisciplinary collaboration, personalized treatment approaches, and the development of new diagnostic tools. Moreover, this work offers practical research directions for both the academic community and clinical practice, driving continued advancement in this domain.

Faecal Cytolysin is Associated With Worse Survival in Patients With Primary Sclerosing Cholangitis

BACKGROUND AND AIMS

Primary sclerosing cholangitis (PSC) is an immune-related cholangiopathy without treatment options beyond liver transplantation. The gut-liver axis, especially the role of gut microbes, has emerged as a crucial pathway contributing to PSC pathogenesis. Recent research has revealed Enterococcus (E.) faecalis and its virulence factor cytolysin to increase mortality risk in patients with alcohol-associated hepatitis. Thus, we studied the role of enterococci, particularly E. faecalis and its virulence factor genes cytolysin and gelatinase, in faecal samples from patients with PSC.

METHODS

To assess the relevance of Enterococcus species, we performed 16S rRNA gene amplicon analysis in faecal samples from 60 patients with PSC. We validated our findings by qPCR of faecal microbial DNA in an extended cohort of 105 patients with PSC, 104 patients with inflammatory bowel disease (IBD) and 68 healthy subjects.

RESULTS

High-throughput 16S rRNA amplicon analysis revealed an increased relative abundance of enterococci in PSC patients compared with healthy controls and IBD patients, respectively, (p < 0.0001). PSC patients with high enterococci abundance had a decreased probability of transplant-free survival (p = 0.028). E. faecalis and its virulence factors cytolysin and gelatinase were more abundant in patients with PSC. Higher faecal cytolysin was associated with lower overall survival (p = 0.04), while survival was independent of gelatinase levels.

CONCLUSION

Our data highlight the association of E. faecalis and faecal cytolysin with lower survival in patients with PSC. These data should prompt further research into the pathogenic role of cytolysin-positive E. faecalis, and to explore its role as a potential therapeutic target.

Analysis of the prognostic efficacy of syndecan-1 for patients with ACLF and its functional role in liver regeneration

BACKGROUND

Acute-on-chronic liver failure (ACLF) is a syndrome characterized by systemic inflammation with a high short-term mortality rate. Syndecan-1 (SDC-1) can independently predict the 90-day mortality of patients with septic shock. However, the role of SDC-1 in ACLF remains unknown.

METHODS

In this study, serum SDC-1 levels were examined in 2 cohorts, which included 174 ACLF patients. And a mouse ACLF model induced by tetrachloride, lipopolysaccharide, and D-galactosamine was established, to evaluate the effects of sulodexide and heparan sulfate (side chains of SDC-1) on ACLF in vivo.

RESULTS

Baseline serum SDC-1 levels in 101 ACLF patients (847.72, 499.79-1511.37 ng/ml) were significantly higher than in healthy controls (33.58, 27.08-43.34 ng/ml) (P < 0.0001). The baseline SDC-1 levels of patients who died or accepted a liver transplantation within 90 days were markedly higher than those of patients who survived (P < 0.05). A novel prognostic model (UIAS) based on upper gastrointestinal bleeding, INR, age, and SDC-1 was developed. The AUROC of the UIAS score for 28-day deterioration in ACLF patients was 0.884, indicating an obviously greater predictive performance for the outcomes of ACLF than those of the Child-Pugh (AUROC = 0.646), MELD (AUROC = 0.713), and COSSH-ACLF II scores (AUROC = 0.713). Moreover, we found that heparan sulfate and sulodexide could increase the expression of SDC-1 and attenuate liver injury, by promoting liver regeneration and inhibiting cell apoptosis through the activation of JAK1/STAT3 signalling.

CONCLUSIONS

Collectively, our findings suggest that SDC-1 represents a potential prognostic and therapeutic target for ACLF and should be further investigated.

Comparison of different severity scores in correlating hemoglobin levels with the severity of hepatic decompensation: An observational study

BACKGROUND

Chronic liver disease is a growing global health problem, leading to hepatic decompensation characterized by an array of clinical and biochemical complications. Several scoring systems have been introduced in assessing the severity of hepatic decompensation with the most frequent ones are Child-Pugh score, model of end-stage liver disease (MELD) score, and MELD-Na score. Anemia is frequently observed in cirrhotic patients and is linked to worsened clinical outcomes. Although studies have explored anemia in liver disease, few have investigated the correlation of hemoglobin level with the severity of hepatic decompensation.

AIM

To determine the relationship between hemoglobin levels and the severity of decompensated liver disease and comparing the strength of this correlation using the Child-Pugh, MELD, and MELD-Na scores.

METHODS

This cross-sectional study was conducted at a tertiary care hospital with 652 decompensated liver disease patients enrolled in the study. Data was collected on demographics, clinical history, and laboratory findings, including hemoglobin levels, bilirubin, albumin, prothrombin time (international normalized ratio), sodium, and creatinine. The Child-Pugh, MELD, and MELD-Na scores were calculated. Statistical analysis was performed using Statistical Package for the Social Sciences version 26, and correlations between hemoglobin levels and severity scores were assessed using Spearman's correlation coefficient.

RESULTS

The study included 405 males (62.1%) and 247 females (37.9%) with an average age of 58.8 years. Significant inverse correlations were found between hemoglobin levels and Child-Pugh, MELD, and MELD-Na scores (P < 0.01), with the MELD scoring system being the strongest correlator among all. One-way analysis of variance revealed significant differences in hemoglobin levels across the severity groups of each scoring system (P = 0.001). Tukey's post hoc analysis confirmed significant internal differences among each severity group.

CONCLUSION

Understanding the correlation between hemoglobin and liver disease severity can improve patient management by offering insights into prognosis and guiding treatment decisions.

A Comprehensive Review of the Usefulness of Prebiotics, Probiotics, and Postbiotics in the Diagnosis and Treatment of Small Intestine Bacterial Overgrowth

Small intestinal bacterial overgrowth (SIBO) is a disorder characterized by the excessive growth of bacteria in the small intestine. Bacterial overgrowth disrupts the bacterial balance and can lead to abdominal pain, weight loss, and gastrointestinal symptoms, including bloating, diarrhea, and malabsorption. SIBO is widespread in the population. There are two main methods for diagnosing SIBO: breath tests and bacterial culture. The most commonly used method is a breath test, which enables the division of SIBO into the following three types: hydrogen-dominant (H-SIBO), methane-dominant (CH4-SIBO), and hydrogen/methane-dominant (H/CH4-SIBO). This comprehensive review aims to present the current knowledge on the use of prebiotics, probiotics, and postbiotics in the context of SIBO. For this purpose, medical databases such as MEDLINE (PubMed) and Scopus were analyzed using specific keywords and their combinations. This review is based on research studies no older than 10 years old and those using only human models. In summary, clinical studies have shown that the efficacy of SIBO therapy can be increased by combining antibiotics with probiotics, especially in vulnerable patients such as children and pregnant women. The further development of diagnostic methods, such as point of care testing (POCT) and portable devices, and a better understanding of the mechanisms of biotics action are needed to treat SIBO more effectively and improve the quality of life of patients.

Value of gadoxetic acid-enhanced MR imaging for preoperative prediction of future liver regeneration after hemihepatectomy

PURPOSE

Liver resection is currently considered the most effective treatment for patients with liver cancer. To the best of our knowledge, no study has investigated the association between gadoxetic acid-enhanced magnetic resonance imaging (MRI) findings and liver regeneration in patients who underwent hemihepatectomy. We aimed to clarify the relationship between the signal intensity (SI) of the liver parenchyma on gadoxetic acid-enhanced MRI and the degree of liver regeneration in patients who underwent hemihepatectomy.

MATERIALS AND METHODS

Forty-one patients who underwent gadoxetic acid-enhanced MRI before hemihepatectomy were enrolled. We calculated the liver-to-erector spinae muscle SI ratio (LMR) in the hepatobiliary phase and the precontrast images. ΔLMR was calculated using the following equation: ΔLMR = (LMR in the hepatobiliary phase-LMR in the precontrast image)/LMR in the precontrast image. The preoperative and postoperative remnant liver volumes (LVs) were calculated using CT volumetry. We calculated the resection rate (RR) and liver regeneration index (LRI) using the following formulas: RR = Resected LV/Total LV × 100 and LRI = (postoperative remnant LV-preoperative remnant LV)/preoperative remnant LV × 100. The relationships among LRI, imaging, and clinicopathological factors were analyzed.

RESULTS

Univariate analysis showed RR and ΔLMR showed a positive correlation with LRI (ρ = 0.4133, p = 0.0072 and ρ = 0.7773, p < 0.001, respectively). Spleen volume showed a negative correlation with LRI (ρ = -0.3138, p = 0.0486). Stepwise multiple regression analysis showed ΔLMR and RR were independently correlated with LRI (β coefficient = 44.8771, p = 0.0198 and β coefficient = 1.9653, p < 0.001, respectively).

CONCLUSION

ΔLMR may serve as a preoperative predictor of liver regeneration in patients undergoing hemihepatectomy.

The Modified Albumin-Bilirubin (ALBI) Grade Reflect the Fate of Limb Prognosis in Patients with Chronic Limb-Threatening Ischemia

BACKGROUND

To examine the influence of liver function on patients with chronic limb-threatening ischemia (CLTI), we classified patients with CLTI after revascularization according to their modified albumin-bilirubin (ALBI) grades.

METHODS

We retrospectively analyzed single-center data of patients who underwent revascularization for CLTI between 2015 and 2020. Patients were classified with ALBI grades 1, 2a, and 2b and 3 according to the ALBI score, which was calculated, based on serum albumin and total bilirubin levels. The endpoints were the 2-year amputation-free survival (AFS) and 1-year wound healing rates.

RESULTS

We included 190 limbs in 148 patients, and 50, 54, and 86 cases were assigned as grade 1, 2a, and 2b and 3, respectively. The 2-year AFS rates for the grade 1, 2a, and 2b and 3 groups were 79 ± 6%, 66% ± 7%, and 45 ± 6%, respectively (P < 0.01). One-year cumulative wound healing rates for grade 1, 2a, and 2b and 3 groups were 68 ± 7%, 69% ± 6%, and 48% ± 5%, respectively (P = 0.01). Multivariate Cox proportional hazard analyses identified age (≥75 years), dependent ambulatory status, and modified ALBI grades 2b and 3 compared with grades 1 and 2a as significant independent predictors of AFS. The dependent ambulatory status and Wound, Ischemia, and foot Infection classification stage 4 were significant negative predictors of wound healing.

CONCLUSIONS

Many patients with CLTI had high modified ALBI grades, and impaired liver function classified as modified ALBI grade 2b and 3 is a robust negative predictor of AFS.

Efficacy of Atezolizumab Plus Bevacizumab-Transcatheter Arterial Chemoembolization Sequential Therapy for Patients with Intermediate-Stage Hepatocellular Carcinoma

This retrospective study aimed to evaluate the impact of atezolizumab plus bevacizumab-transcatheter arterial chemoembolization (TACE) sequential therapy in unresectable hepatocellular carcinoma (HCC), especially in patients with intermediate-stage HCC. A total of 212 patients were enrolled and categorized into the Atez/Bev-TACE sequential therapy (n = 23) or Atez/Bev monotherapy group (n = 189) between 2020 and 2024. Of these, patients with intermediate-stage HCC were categorized into the Atez/Bev-TACE sequential (n = 18) or Atez/Bev monotherapy group (n = 91). The best objective response rate, disease control rate, and median progression-free survival (PFS) after TACE were 73.9%, 82.6%, and 6.1 months, respectively. The PFS after TACE was significantly higher in the Atez/Bev sequential therapy group than in the no-Atez/Bev-administration group after TACE (6.9 months vs. 5.0 months, p = 0.025). The median overall survival (OS) was significantly higher in the Atez/Bev-TACE sequential therapy group than in the Atez/Bev monotherapy group for intermediate-stage HCC (34.9 months vs. 17.8 months; p = 0.016). Independent factors associated with OS were low alpha-fetoprotein levels, modified albumin-bilirubin 1 or 2a levels, and Atez/Bev-TACE sequential therapy. Atez/Bev-TACE sequential therapy improved prognosis compared with Atez/Bev monotherapy in patients with intermediate-stage HCC. Moreover, Atez/Bev should be readministered after TACE.

Strategy and Outcomes of Cardiac Surgery in Patients With Cirrhosis: Comprehensive Approach With Liver Transplant Program

BACKGROUND

Cardiac surgery is considered a contraindication in patients with advanced liver cirrhosis (LC) due to increased mortality and morbidity. There are limited data on the treatment strategy and management of this population. We aimed to present our strategy and evaluate the clinical outcome of cardiac surgery in patients with LC.

METHODS

Our strategy was (i) to list patients for liver transplant (LT) at the time of cardiac surgery; (ii) to maintain high cardiopulmonary bypass (CPB) flow (index up to 3.0 L/min/m2) based on hyper-dynamic states due to LC; and (iii) to proceed to LT if patients' liver function deteriorated with an increasing model for end-stage liver disease Na (MELD-Na) score after cardiac surgery. Thirteen patients (12 male and 1 female [mean age, 63.0]) with LC who underwent cardiac surgery between 2017 and 2024 were retrospectively analyzed.

RESULTS

Six patients were listed for LT. Indications for cardiac surgery included coronary artery disease (N = 7), endocarditis (N = 2), and tricuspid regurgitation (N = 1), tricuspid stenosis (N = 1), mitral regurgitation (N = 1), and hypertrophic obstructive cardiomyopathy (N = 1). The Child-Pugh score was A in five, B in six, and C in one patient. The procedure included coronary artery bypass grafting (N = 6), single valve surgery (mitral valve [N = 2] and tricuspid valve [N = 1]), concomitant aortic and tricuspid valve surgery (N = 2), and septal myectomy (N = 1). Two patients had a history of previous sternotomy. The perfusion index during CPB was 3.1 ± 0.5 L/min/m2. Postoperative complications include pleural effusion (N = 6), bleeding events (N = 3), acute kidney injury (N = 1), respiratory failure requiring tracheostomy (N = 2), tamponade (N = 1), and sternal infection (N = 1). There was no in-hospital death. There was one remote death due to COVID-19 complication. Preoperative and postoperative highest MELD-Na score among listed patients was 15.8 ± 5.1 and 19.3 ± 5.3, respectively. Five patients underwent LT (1, 5, 8, 16, and 24 months following cardiac surgery) and one patient remains on the list. Survival rates at 1 and 3 years are 100% and 75.0%, respectively.

CONCLUSION

Cardiac surgery maintaining high CPB flow with LT backup is a feasible strategy in an otherwise inoperable patient population with an acceptable early and midterm survival when performed in a center with an experienced cardiac surgery and LT program.

Initial clinical experience with durvalumab plus tremelimumab in patients with unresectable hepatocellular carcinoma in real‑world practice

Although durvalumab plus tremelimumab (Dur/Tre) has been approved as first-line therapy for patients with unresectable hepatocellular carcinoma (u-HCC), its outcomes in real-world clinical practice are unclear. The present study aimed to evaluate the efficacy and safety of Dur/Tre treatment. This multicenter study was conducted between March 2023 and January 2024, and included 120 patients with u-HCC treated with Dur/Tre. Among the patients, 44 had no history of systemic treatment. Progression-free survival (PFS), therapeutic response and adverse events (AEs) were assessed. The objective response rate (ORR) and disease control rates (DCR) were 15.8 and 53.3%, respectively. The median PFS was 3.9 months. The incidence rates of AEs of any grade and those grade 3 or higher were 83.3 and 36.7%, respectively. Liver injury was the most frequent AE of any grade and grade 3 or higher. Although there was no significant difference in ORR and PFS between the first and later line groups (ORR 15.8 vs. 15.7%, P=0.986; PFS 4.5 vs. 3.6 months, P=0.213), there was a significant difference in DCR between the two groups (65.8 vs. 45.9%, P=0.034). No significant differences were noted between the first- and later-line treatment groups regarding the incidence rate of AEs. Decision tree analysis revealed that poor liver function and advanced age were significant variables for discontinuation owing to AEs. In conclusion, Dur/Tre as first-line therapy had better disease control responses compared with later-line therapy; however, this regimen should be carefully administered to patients with deteriorating hepatic function or advanced age.

Prognostic Role of Basal Serum Alpha-Fetoprotein in Patients with Hepatocellular Carcinoma Suitable for Curative Treatment

Background and Objectives: Serum alpha-fetoprotein (AFP) is a recognized affordable oncological marker in patients with hepatocellular carcinoma (HCC). However, AFP's prognostic role has been assessed mainly after specific treatments, and no unanimously recognized cut-offs have been identified. The aim of this study is to investigate the prognostic role of different basal AFP cut-offs on survival and HCC course. Materials and Methods: In this single-center, retrospective study, all patients newly diagnosed with HCC between January 2009 and December 2021 were prospectively enrolled. Only patients suitable for curative HCC treatments were included in the analyses. Patients were stratified according to AFP cut-offs of 20, 200, 400, and 1000 ng/mL, which were correlated with survival outcomes and clinical parameters. Results: A total of 266 patients were analyzed, with a median follow-up time of 41.5 months. Median overall survival (OS) of all cohort was 43 months. At the multivariate Cox-regression analysis, AFP value ≥ 1000 ng/mL correlated with impaired OS (1-year OS: 67% vs. 88%, 5-year OS: 1% vs. 43%; p = 0.005); other risk factors were tumor dimension ≥ 5 cm (HR 1.73; p = 0.002), Child-Pugh class B-C (HR 1.72; p = 0.002), BCLC stage A (vs. 0) (HR 2.4; p = 0.011), and malignant portal vein thrombosis (HR 2.57; p = 0.007). AFP ≥ 1000 ng/mL was also associated with a reduced recurrence-free survival (HR 2.0; p = 0.038), while starting from AFP ≥ 20 ng/mL, a correlation with development of HCC metastases over time (HR 3.5; p = 0.002) was seen. AFP values ≥ 20 ng/mL significantly correlated with tumor size and higher histological grading; starting from AFP values ≥ 400 ng/mL, a significant correlation with Child-Pugh class B-C and female gender was also observed. Conclusions: Basal AFP correlates with relevant outcomes in patients with HCC. It could help identify patients at a higher risk of worse prognosis who might benefit from personalized surveillance and treatment programs. Prospective studies are needed to confirm these results.

The Relationship Between Conventionally Obtained Serum-Based Liver Function Indices and Intravoxel Incoherent Motion Diffusion-Weighted Imaging and Magnetic Resonance Elastography in Patients With Hepatocellular Carcinoma

OBJECTIVES

To investigate the relationship between conventionally obtained serum-based biochemical indices and intravoxel incoherent motion imaging (IVIM) parameters compared with magnetic resonance elastography (MRE).

METHODS

Patients with hepatocellular carcinoma who underwent ≥2 liver magnetic resonance imaging (MRI) scan, including IVIM and MRE, between 2017 and 2020 and biochemical testing within 1 week before or after MRI were included in this study. Biochemical tests were performed to determine the albumin-bilirubin (ALBI) score and modified ALBI (mALBI) grade, aspartate aminotransferase to platelet ratio index (APRI), and fibrosis-4 index (FIB-4). The diffusion coefficient ( D ), pseudo-diffusion coefficient ( D *), fractional volume occupied by flowing spins ( f ), and apparent diffusion coefficient were calculated for IVIM. The correlations between (1) the imaging parameters and biochemical indices and (2) the changes in mALBI grades and imaging parameters were evaluated.

RESULTS

This study included 98 scans of 40 patients (31 men; mean age, 67.7 years). The correlation analysis between the biochemical and IVIM parameters showed that ALBI score and D* had the best correlation ( r = -0.3731, P < 0.001), and the correlation was higher than that with MRE ( r = 0.3289, P < 0.001). However, among FIB-4, APRI, and MRI parameters, MRE outperformed IVIM parameters (MRE and FIB-4, r = 0.3775, P < 0.001; MRE and APRI, r = 0.4687, P < 0.001). There were significant differences in the changes in MRE among the 3 groups (improved, deteriorated, and unchanged mALBI groups) in the analysis of covariance ( P = 0.0434). There were no significant changes in IVIM.

CONCLUSIONS

Intravoxel incoherent motion imaging has the potential to develop into a more readily obtainable method of liver function assessment.

Identifying optimal candidates for autologous peripheral blood stem cell therapy in patients with decompensated liver cirrhosis: a prognostic scoring system

BACKGROUND

Stem cell transplantation shows great potential to improve the long-term survival of cirrhosis patients. However, therapeutic effects may not be homogeneous across the whole study population. This study constructed an easy-to-use nomogram to improve prognostic prediction and aid in treatment decision making for cirrhotic patients.

METHODS

From August 2005 to April 2019, 315 patients with decompensated cirrhosis receiving autologous peripheral blood stem cell (PBSC) transplantation were enrolled in this study. They were randomly classified into training (2/3) and validation (1/3) groups. A predictive model was developed using Cox proportional hazard models and subsequently validated. The predictive performance of the model was evaluated and also compared with other prognostic models.

RESULTS

Age, creatinine, neutrophil-to-lymphocyte ratio, and Child-Turcotte-Pugh class were included in the nomogram as prognostic variables. The nomogram showed high discrimination power concerning the area under receiver operating characteristic curves (3/5-year AUC: 0.742/0.698) and good consistency suggested by calibration plots. Patients could be accurately stratified into poor- and good-outcome groups regarding liver-transplantation free survival after receiving PBSC therapy (P < 0.001). Compared with poor-outcome group, the liver function of patients listed for liver transplantation in the good-outcome group was significantly improved (P < 0.001). Besides, our nomogram achieved a higher C-index (0.685, 95% CI 0.633-0.738) and better clinical utility compared with other conventional prognostic models.

CONCLUSIONS

The proposed nomogram facilitated an accurate prognostic prediction for patients with decompensated cirrhosis receiving PBSC transplantation. Moreover, it also held the promise to stratify patients in clinical trials or practice to implement optimal treatment regimens for individuals.

Preoperative transarterial chemoembolization (TACE) + liver resection versus upfront liver resection for large hepatocellular carcinoma (≥5 cm): a systematic review and meta-analysis

BACKGROUND

Hepatocellular carcinoma (HCC) accounts for majority of primary liver cancer. Use of preoperative neoadjuvant transarterial chemoembolization (PN-TACE) may result in tumor shrinkage and improve resectability. This study aims to summarize the outcomes of PN-TACE versus upfront liver resection (Up-LR) in large HCC (≥5 cm).

METHODS

PubMed, Embase, The Cochrane Library, and Scopus were systematically searched till September 2022 for studies comparing PN-TACE versus Up-LR. The primary study outcomes were overall survival (OS), disease-free survival (DFS), and recurrence. Our secondary outcomes were postoperative morbidity and mortality.

RESULTS

There were 12 studies with 15 data sets including 3960 patients (PN-TACE n = 2447, Up-LR n = 1513). Majority (89.5%, n = 1250/1397) of patients had Child's A liver cirrhosis. Incidence of Child's B cirrhosis was higher in PN-TACE compared to Up-LR (Odds ratio (OR) 1.69, 95% CI: 1.18, 2.41, p = 0.004). Pooled hazard ratio (HR) for OS showed no significant difference between PN-TACE and Up-LR (HR 0.87, 95% CI: 0.64, 1.18, p = 0.37), but DFS was superior in PN-TACE (HR 0.79, 95% CI: 0.63, 0.99, p = 0.04). Subgroup analysis based on study design failed to show any significant effect in randomized controlled trials (n = 2/15 data sets). However, operating time (mean difference (MD) 31.94 min, 95% CI: 2.42, 61.45, p = 0.03) and blood loss (MD 190.93 ml, 95% CI: 10.22, 317.65, p = 0.04) were higher in PN-TACE. Intrahepatic and extrahepatic recurrence, post-operative morbidity and in-hospital mortality were comparable between PN-TACE and Up-LR.

CONCLUSION

In retrospective studies, PN-TACE resulted in superior DFS compared to Up-LR. However, this may be confounded by selection bias.

Spontaneous muscle haematoma in a patient with cirrhosis

Decompensated liver disease is associated with alterated haemostasis that can either lead to spontaneous bleeding or development of thrombosis. Alcohol consumption coupled with advanced liver disease favours spontaneous bleeding. There have been only few documented cases of spontaneous muscle haematoma (SMH) in patients with cirrhosis. The pathogenesis of SMH is hypothesised to be multifactorial and it has been seen in patients on anticoagulation or with haemostatic disorders. We report a case of alcohol-related cirrhosis presenting with an expanding, voluminous haematoma in the intermuscular plane between the trapezius and the teres major muscles. This patient also had a retroperitoneal haemorrhage, clinically evidenced by the Grey Turner's and Cullen's signs. Haemorrhage was confirmed radiologically by CT. The patient was managed in an intensive care facility and treated with multiple blood products, including packed red blood cells, fresh frozen plasma and cryoprecipitates. However, as his clinical condition deteriorated, he required surgical intervention by incision and drainage, followed by evacuation. Early identification of coagulopathy and aggressive treatment are essential in these cases of cirrhosis to avoid unfavourable outcomes.

Current status of preoperative risk assessment for posthepatectomy liver failure in patients with hepatocellular carcinoma

Liver resection is an effective therapeutic option for patients with hepatocellular carcinoma. However, posthepatectomy liver failure (PHLF) remains a major cause of hepatectomy-related mortality, and the accurate prediction of PHLF based on preoperative assessment of liver functional reserve is a critical issue. The definition of PHLF proposed by the International Study Group for Liver Surgery has gained acceptance as a standard grading criterion. Liver function can be estimated using a variety of parameters, including routine blood biochemical examinations, clinical scoring systems, dynamic liver function tests, liver stiffness and fibrosis markers, and imaging studies. The Child-Pugh score and model for end-stage liver disease scores are conventionally used for estimating liver decompensation, although the alternatively developed albumin-bilirubin score shows superior performance for predicting hepatic dysfunction. Indocyanine green clearance, a dynamic liver function test mostly used in Japan and other Asian countries, serves as a quantitative estimation of liver function reserve and helps determine indications for surgical procedures according to the estimated risk of PHLF. In an attempt to improve predictive accuracy, specific evaluation of liver fibrosis and portal hypertension has gained popularity, including liver stiffness measurements using ultrasonography or magnetic resonance elastography, as well as noninvasive fibrosis markers. Imaging modalities, including Tc-99m-labeled galactosyl serum albumin scintigraphy and gadolinium-enhanced magnetic resonance imaging, are used for preoperative evaluation in combination with liver volume. This review aims to provide an overview of the usefulness of current options for the preoperative assessment of liver function in predicting PHLF.

Prognostic value of ascites in patients with liver cirrhosis undergoing cardiac surgery

INTRODUCTION

Mild or moderate liver cirrhosis increases the risk of complications after cardiac surgery. Ascites is the most common complication associated with liver cirrhosis. However, the prognostic value of ascites on postoperative morbidity and mortality after cardiac surgery remains uninvestigated.

METHODS

A retrospective study included 69 patients with preoperatively diagnosed liver cirrhosis who underwent cardiac surgery between January 2009 and January 2018 at the Department of Cardiothoracic Surgery, University Hospital of Cologne, Germany. The patients were divided into ascites and non-ascites groups based on preoperatively diagnosed ascites. Thirty-day mortality, postoperative complications, length of stay, and blood transfusions were analyzed postoperatively.

RESULTS

Out of the total of 69 patients, 14 (21%) had preoperatively diagnosed ascites. Ascites group had more postoperative complications such as blood transfusions (packed red blood cells: 78.6% vs. 40.0%, p = 0.010; fresh frozen plasma: 57.1% vs. 29.1%, p = 0.049), acute kidney injury (78.6% vs. 45.5%, p = 0.027), longer ICU stay (8 vs. 3 days, p = 0.044) with prolonged mechanical ventilation (57.1% vs. 23.6%, p = 0.015) and tracheotomy (28.6% vs. 3.6%, p = 0.003). The 30-day mortality rate was significantly higher in the ascites group than in the non-ascites group (35.7% vs. 5.5%, p = 0.002).

CONCLUSION

Ascites should be implemented in preoperative risk score assessments in cirrhotic patients undergoing cardiac surgery. Preoperative treatment of ascites could reduce the negative impact of ascites on postoperative complications after cardiac surgery. However, this needs to be thoroughly investigated in prospective randomized clinical trials.

A model for individualized prediction of liver-related death in outpatients with alcohol-associated cirrhosis

INTRODUCTION

In alcohol-associated cirrhosis, an accurate estimate of the risk of death is essential for patient care. We developed individualized prediction charts for 5-year liver-related mortality among outpatients with alcohol-associated cirrhosis that take into account the impact of abstinence.

METHODS

We collected data on outpatients with alcohol-associated cirrhosis in a prospective registry. The model was derived, internally and externally validated, and compared with the Child-Pugh and the Model For End-Stage Liver Disease (MELD) scores.

RESULTS

A total of 527 and 127 patients were included in the derivation and validation data sets, respectively. A model was developed based on the 3 variables independently associated with liver-related mortality in multivariate analyses (age, Child-Pugh score, and abstinence). In the derivation data set, the model combining age, Child-Pugh score, and abstinence outperformed the Child-Pugh and the MELD scores. In the validation data set, the Brier score was lower for the model (0.166) compared with the Child-Pugh score (0.196, p = 0.008) and numerically lower compared with the MELD score (0.190) (p = 0.06). The model had the greatest AUC (0.77; 95% CI 0.68-0.85) compared with the Child-Pugh score (AUC = 0.66; 95% CI 0.56-0.76, p = 0.01) and was numerically higher than that of the MELD score (AUC = 0.66; 95% CI 0.56-0.78, p = 0.06). Also, the Akaike and Bayesian information criterion scores were lower for the model (2163; 2172) compared with the Child-Pugh (2213; 2216) or the MELD score (2205; 2208).

CONCLUSION

A model combining age, Child-Pugh score, and abstinence accurately predicts liver-related death at 5 years among outpatients with alcohol-associated cirrhosis. In this study, the model outperformed the Child-Pugh and the MELD scores, although the AUC and the Brier score of the model were not statically different from the MELD score in the validation data set.

A modified Child-Turcotte-Pugh score based on plasma ammonia predicts survival for patients with decompensated cirrhosis

BACKGROUND

Plasma ammonia has been shown to be an independent prognostic factor for patients with liver cirrhosis.

AIM

We aimed to investigate the discrimination and calibration of a new prognostic model (aCTP) based on plasma ammonia (Amm) replacing hepatic encephalopathy (HE) in the Child-Turcotte-Pugh (CTP) score.

DESIGN

Diagnostic test, paired design.

METHODS

Baseline Amm levels were corrected to the upper limit of normal (Amm-ULN). We designed the new model based on the cut-off value of Amm-ULN in the observational cohort of 554 clinically stable cirrhotic patients from January 2012 to July 2019. External validation was carried out using prospective data from 185 patients with liver cirrhosis.

RESULTS

Our analysis showed that each 1-point increase in Amm-ULN was associated with a 2-fold increase in the likelihood of mortality [hazard ratio (HR), 2.06; 95% CI: 1.81-2.36, P < 0.001]. In the aCTP score, Amm-ULN < 1.0 was defined as a score of 1, 1.0 ≤ Amm-ULN < 1.4 as 2 and ≥1.4 as 3. The survival curves among three aCTP grades were significantly different (P < 0.0001). The aCTP score showed the better agreements between predicted and observed events in the validating cohorts than the CTP score (C-statistics: 0.75 and 0.69, P < 0.001). The aCTP score showed inspiring power to predict acute decompensation (C-statistics: 0.76; 95% CI: 0.71-0.81) and acute-on-chronic liver failure (C-statistics: 0.81; 95% CI: 0.77-0.86).

CONCLUSION

This study demonstrates the feasibility and the potential for plasma Amm replacing HE (aCTP) to enhance the prognostication of transplant-free survival provided by the CTP score for patients with decompensated cirrhosis.

PRO-C3 is a predictor of clinical outcomes in distinct cohorts of patients with advanced liver disease

Background & Aims

Fibroblast activity is a key feature of fibrosis progression and organ function loss, leading to liver-related complications and mortality. The fibrogenesis marker, PRO-C3, has been shown to have prognostic significance in relation to fibrosis progression and as a treatment efficacy marker. We investigated whether PRO-C3 was prognostic for clinical outcome and mortality in two distinct cohorts of compensated cirrhosis.

Methods

Cohort 1 was a rapid fibrosis progression cohort including 104 patients with HCV and biopsy-proven Ishak fibrosis stage ≥3 without prior clinical events. Cohort 2 was a prospective cohort including 172 patients with compensated cirrhosis of mixed aetiology. Patients were assessed for clinical outcomes. PRO-C3 was assessed in serum at baseline in cohorts 1 and 2, and compared with model for end-stage liver disease and albumin-bilirubin (ALBI) scores.

Results

In cohort 1, a 2-fold increase in PRO-C3 was associated with 2.7-fold increased hazard of liver-related events (95% CI 1.6-4.6), whereas a one unit increase in ALBI score was associated with a 6.5-fold increased hazard (95% CI 2.9-14.6). In cohort 2, a 2-fold increase in PRO-C3 was associated with a 2.7-fold increased hazard (95% CI 1.8-3.9), whereas a one unit increase in ALBI score was associated with a 6.3-fold increased hazard (95% CI 3.0-13.2). A multivariable Cox regression analysis identified PRO-C3 and ALBI as being independently associated with the hazard of liver-related outcomes.

Conclusions

PRO-C3 and ALBI were independent prognostic factors for predicting liver-related clinical outcomes. Understanding the dynamic range of PRO-C3 might enhance its use for both drug development and clinical practice.

Impact and Implications

We tested novel proteins of liver scarring (PRO-C3) in two groups of liver patients with advanced disease to see if they could predict clinical events. We found that this marker and an established test called ALBI were both independently associated with future liver-related clinical outcomes.

Derivation and Validation of a Prognostic Model for Acute Decompensated Cirrhosis Patients

Background

Acute decompensated cirrhosis (AD) is related to high medical costs and high mortality. We recently proposed a new score model to predict the outcome of AD patients and compared it with the common score model (CTP, MELD and CLIF-C AD score) in the training and validation sets.

Materials and Methods

A total of 703 patients with AD were enrolled from The First Affiliated Hospital of Nanchang University between December 2018 and May 2021. These patients were randomly assigned to the training set (n=528) and validation set (n=175). Risk factors affecting prognosis were identified by Cox regression analysis and then used to establish a new score model. The prognostic value was determined by the area under the receiver operating characteristic curve (AUROC).

Results

A total of 192 (36.3%) patients in the training cohort and 51 (29.1%) patients in the validation cohort died over the course of 6 months. A new score model was developed with predictors including age, bilirubin, INR, WBC, albumin, ALT and BUN. The new prognostic score (0.022×Age + 0.003×TBil + 0.397×INR + 0.023×WBC- 0.07×albumin + 0.001×ALT + 0.038×BUN) for long-term mortality was superior to three other scores based on both training and internal validation studies.

Conclusion

This new score model appears to be a valid tool for assessing the long-term survival of AD patients, improving the prognostic value compared with the CTP, MELD and CLIF-C AD scores.

Telephone follow-up contributes to improving adherence and treatment duration in patients with hepatocellular carcinoma treated with lenvatinib

BACKGROUND AND AIM

This study aimed to investigate whether telephone follow-up by clinical pharmacists for unresectable hepatocellular carcinoma (HCC) patients treated with lenvatinib (LEN) contributes to improved adherence and treatment duration for LEN.

METHODS

This retrospective study enrolled 132 patients with HCC who were treated with LEN. The patients were classified into non-telephone follow-up (n = 32) or telephone follow-up groups (n = 100) [the latter group was further classified into family-pharmacist (FP) telephone follow-up (n = 18), or hospital family-pharmacist (HFP) telephone follow-up (n = 82) groups].

RESULTS

The progression-free survival (PFS) in the telephone follow-up group was significantly higher than that in the non-telephone follow-up group (PFS 6.1 months vs 3.7 months, P = 0.001, respectively). Although treatment duration was significantly longer in the telephone follow-up group than in the non-telephone follow-up group [median treatment duration: 10.4 months vs 4.1 months, P = 0.001, respectively.], no significant differences were noted between the HFP telephone follow-up group and FP telephone follow-up groups (10.3 months vs 13.3 months, P = 0.543). Self-interruption and adverse-event discontinuation in the HFP-telephone follow-up group were significantly lower than those in the FP-telephone and non-telephone groups (0% vs 11.1% vs 18.8%; P < 0.001, 25.6% vs 33.3% vs 53.1%; P = 0.022, respectively).

CONCLUSIONS

Telephone follow-up contributes to prolonged treatment duration for LEN in patients with HCC treated. Moreover, telephone follow-up with an HFP may further improve treatment adherence.

Sarcopenia negatively affects postoperative short-term outcomes of patients with non-cirrhosis liver cancer

BACKGROUND

Literature review have shown that sarcopenia substantially alters the postoperative outcomes after liver resection for malignant tumors. However, these retrospective studies do not distinguish cirrhotic and non-cirrhotic liver cancer patients, nor combine the assessment of muscle strength in addition to muscle mass. The purpose of this study is to study the relationship between sarcopenia and short-term outcomes after hepatectomy in patients with non-cirrhotic liver cancer.

METHODS

From December 2020 to October 2021, 431 consecutive inpatients were prospectively enrolled in this study. Muscle strength and mass were assessed by handgrip strength and the skeletal muscle index (SMI) on preoperative computed tomographic scans, respectively. Based on the SMI and the handgrip strength, patients were divided into four groups: group A (low muscle mass and strength), group B (low muscle mass and normal muscle strength), group C (low muscle strength and normal muscle mass), and group D (normal muscle mass and strength). The main outcome was major complications and the secondary outcome was 90-d Readmission rate.

RESULTS

After strictly exclusion, 171 non-cirrhosis patients (median age, 59.00 [IQR, 50.00-67.00] years; 72 females [42.1%]) were selected in the final analysis. Patients in group A had a statistically significantly higher incidence of major postoperative complications (Clavien-Dindo classification ≥ III) (26.1%, p = 0.032), blood transfusion rate (65.2%, p < 0.001), 90-day readmission rate (21.7%, p = 0.037) and hospitalization expenses (60,842.00 [IQR, 35,563.10-87,575.30], p < 0.001) than other groups. Sarcopenia (hazard ratio, 4.21; 95% CI, 1.44-9.48; p = 0.025) and open approach (hazard ratio, 2.56; 95% CI, 1.01-6.49; p = 0.004) were independent risk factors associated with major postoperative complications.

CONCLUSIONS

Sarcopenia is closely related to poor short-term postoperative outcomes in non-cirrhosis liver cancer patients and the assessment that combines muscle strength and muscle mass can simply and comprehensively identify it.

Graft-to-recipient weight ratio exerts nonlinear effects on prognosis by interacting with donor liver macrosteatosis

AIM

To investigate the interactions between the graft-to-recipient weight ratio (GWRWR) and other risk factors responsible for inferior allograft outcomes.

METHODS

A total of 362 patients who received liver transplantation (LT) were enrolled. Indicators such as graft/recipient weight and other prognostic factors were collected. Comparisons of indicators and survival analysis were performed in groups categorized by the GWRWR. Interactions of large-for-size grafts (LFSGs) with graft macrosteatosis (MaS) were evaluated in terms of relative excess risk caused by interaction (RERI) and attributable proportion (AP). Cytoscape visualized the role of LFSGs in the risk profile for poor prognosis.

RESULTS

Based on the GWRWR, LT cases can be categorized into three subgroups, standard (1%-2.5%), optimal (2.5%-3.0%), and inferior prognosis (>3.0%). Survival analysis confirmed clear separations in cases categorized by the above-defined limits on the GWRWR (P < 0.05). LFSGs caused inferior prognosis by initiating positive interactions with MaS severity.

CONCLUSION

The GWRWR exerted nonlinear effects on prognosis in deceased donor LT cases. LFSGs (GWRWR > 3.0%) caused inferior outcomes, while grafts sized within (2.5%-3.0%) had optimal post-transplant prognosis. MaS increased the risk of poor prognosis by exerting positive synergistic effects on LFSGs.

Efficacy evaluation and prognostic risk factors analysis of precise hepatectomy in the treatment of intermediate and advanced hepatocellular carcinoma

BACKGROUND

To investigate the efficacy of precise hepatectomy in the treatment of patients with intermediate and advanced hepatocellular carcinoma and analyze the risk factors affecting prognosis.

METHODS

Totally 104 patients with intermediate and advanced hepatocellular carcinoma from January 2018 to January 2019 were enrolled in this retrospective analysis. Of these, four patients lost to follow-up. Logistic regression was conducted to explore the odds ratio (OR) and 95% confidence interval (CI).

RESULTS

Compared with the control group, the precise hepatectomy decreased intraoperative blood loss (331.2928.91 to 203.29 ± 29.34 ml), operation time (198.29 ± 19.38 to 150.28 ± 18.27 min), perioperative blood transfusion volume (376.22 ± 25.93 to 228.29 ± 22.19 ml) (all P < 0.001). Logistic regression analysis of study group showed that hepatitis B infection (OR  = 1.746; 95% CI, 1.068-2.976), P  =  0.021, Child-Pugh classification (OR  =  2.319; 95% CI, 1.428-3.213), P < 0.001, Eastern Cooperative Oncology Group (ECOG) score (OR  =  2.287; 95% CI, 1.098-3.876; P  =  0.013) and Barcelona-Clinic Liver Cancer (BCLC) staging (OR = 2.029; 95% CI, 1.086-3.671; P = 0.022) were independent risk factors for prognosis of the precise hepatectomy.

CONCLUSION

Hepatitis B virus infection, Child-Pugh grade, ECOG score and BCLC staging grade were the independent risk factors affecting the prognosis of precise hepatectomy.

CLIF-SOFA and CLIF-C scores for the prognostication of acute-on-chronic liver failure and acute decompensation of cirrhosis: A systematic review

BACKGROUND

Acute-on-chronic liver failure (ACLF) is a syndrome characterized by decompensation in individuals with chronic liver disease, generally secondary to one or more extra-hepatic organ failures, implying an elevated mortality rate. Acute decompensation (AD) is the term used for one or more significant consequences of liver disease in a short time and is the most common reason for hospital admission in cirrhotic patients. The European Association for the Study of Liver-Chronic-Liver Failure (EASL-CLIF) Group modified the intensive care Sequential Organ Failure Assessment score into CLIF-SOFA, which detects the presence of ACLF in patients with or without AD, classifying it into three grades.

AIM

To investigate the role of the EASL-CLIF definition for ACLF and the ability of CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD scores for prognosticating ACLF or AD.

METHODS

This study is a literature review using a standardized search method, conducted using the steps following the guidelines for reporting systematic reviews set out by the PRISMA statement. For specific keywords, relevant articles were found by searching PubMed, ScienceDirect, and BioMed Central-BMC. The databases were searched using the search terms by one reviewer, and a list of potentially eligible studies was generated based on the titles and abstracts screened. The data were then extracted and assessed on the basis of the Reference Citation Analysis (https://www.referencecitationanalysis.com/).

RESULTS

Most of the included studies used the EASL-CLIF definition for ACLF to identify cirrhotic patients with a significant risk of short-term mortality. The primary outcome in all reviewed studies was mortality. Most of the study findings were based on an area under the receiver operating characteristic curve (AUROC) analysis, which revealed that CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD scores were preferable to other models predicting 28-d mortality. Their AUROC scores were higher and able to predict all-cause mortality at 90, 180, and 365 d. A total of 50 articles were included in this study, which found that the CLIF-SOFA, CLIF-C ACLF and CLIF-C AD scores in more than half of the articles were able to predict short-term and long-term mortality in patients with either ACLF or AD.

CONCLUSION

CLIF-SOFA score surpasses other models in predicting mortality in ACLF patients, especially in the short-term. CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD are accurate short-term and long-term mortality prognosticating scores.

Predictive Factors for the Prognosis of Alcoholic Liver Cirrhosis

Alcoholic liver cirrhosis (ALC) is a disease with multiple complications and is associated with poor prognosis and significant mortality. Identifying risk factors associated with a poor outcome is important to ensure effective treatment and increase life expectancy. We aimed to evaluate the predictive values of complications regarding mortality in ALC. We retrospectively analyzed 1429 patients with ALC hospitalized between January 2019 and April 2022 at the Institute of Gastroenterology and Hepatology Iasi. The electronic medical records were interrogated to obtain information about demographic data, complications, comorbidities, and prognostic scores: MELD-Na (model for end-stage liver disease-sodium) and CTP (Child−Turcotte−Pugh). Based on uni- and multivariate analysis, independent predictors of mortality were identified. The mean age at diagnosis was 56.15 ± 11.49 years with a ratio of 2:1 in favor of males. There were 296 deaths (20.8%), most of them during the first hospitalization (208/14.6%). It was observed during the univariate analysis that complications of the disease negatively affected the survival rate, significant values being related to infections (sepsis; OR = 21.98; p < 0.001; spontaneous bacterial peritonitis (SBP) (OR = 11.94; p < 0.001) and hepatorenal syndrome (HRS) (OR = 9.35; p < 0.001). The independent predictors, confirmed by multivariate analysis, were the association of variceal bleeding, infections, and hepatic encephalopathy or ascites, each combination being responsible for two out of 10 of the deaths during the first admission. The prognosis of the disease was negatively influenced by the worsening of liver dysfunction and the appearance of complications. The main predictors of mortality were infections, hepatic encephalopathy, variceal bleeding, and hepatorenal syndrome. Improving compliance and strict application of specific follow-up and treatment strategies could contribute to a better prognosis of patients with alcoholic liver cirrhosis.

Seriously Ill Patients' Prioritized Goals and Their Clinicians' Perceptions of Those Goals

CONTEXT

Seriously ill patients whose prioritized healthcare goals are understood by their clinicians are likely better positioned to receive goal-concordant care.

OBJECTIVES

To examine the proportion of seriously ill patients whose prioritized healthcare goal is accurately perceived by their clinician and identify factors associated with accurate perception.

METHODS

Secondary analysis of a multicenter cluster-randomized trial of outpatients with serious illness and their clinicians. Approximately two weeks after a clinic visit, patients reported their current prioritized healthcare goal- extending life over relief of pain and discomfort, or relief of pain and discomfort over extending life - and clinicians reported their perception of their patients' current prioritized healthcare goal; matching these items defined accurate perception.

RESULTS

Of 252 patients with a prioritized healthcare goal, 60% had their goal accurately perceived by their clinician, 27% were cared for by clinicians who perceived prioritization of the alternative goal, and 13% had their clinician answer unsure. Patients who were older (OR 1.03 per year; 95%CI 1.01, 1.05), had stable goals (OR 2.52; 95%CI 1.26, 5.05), and had a recent goals-of-care discussion (OR 1.78, 95%CI 1.00, 3.16) were more likely to have their goals accurately perceived.

CONCLUSION

A majority of seriously ill outpatients are cared for by clinicians who accurately perceive their patients' prioritized healthcare goals. However, a substantial portion are not and may be at higher risk for goal-discordant care. Interventions that facilitate goals-of-care discussions may help align care with goals, as recent discussions were associated with accurate perceptions of patients' prioritized goals.

Shortness of breath due to portopulmonary hypertension and hepatopulmonary syndrome: diagnostic challenges and complex management approach in frail patients

A 60-year-old woman with a background of frailty, non-alcoholic fatty liver disease (NAFLD), cirrhosis and type 2 diabetes mellitus (T2DM), presented with worsening shortness of breath and a drop in oxygen saturation on sitting and standing up. Her chest X-ray demonstrated evidence of upper lobe venous diversion. Given the hypoxia, she had a computed tomography pulmonary angiography (CTPA) to rule out a pulmonary embolism. The only finding from the CTPA was pulmonary hypertension in the absence of any clots in the lungs. An ultrasound of the abdomen confirmed portal hypertension with splenomegaly and a cirrhotic liver, therefore, an initial diagnosis of portopulmonary hypertension and hepatopulmonary syndrome was made. The patient declined an agitated saline contrast echocardiography. Based on frailty she was not deemed to be a suitable candidate for a liver transplant and was discharged with a package of care alongside home oxygen therapy with periodic review in the gastroenterology clinic. She was assessed as stable with no new concerns while on home oxygen and diuretics. This case highlights challenges in diagnosing and managing patients with cirrhosis, portopulmonary hypertension and hepatopulmonary syndrome with a background of complex comorbidities and frailty.

Durable complete response is achieved by balloon-occluded transcatheter arterial chemoembolization for hepatocellular carcinoma

In 2013 and 2014, the development of microcatheters with balloons for the 4-Fr system and new embolization materials provided various options for transarterial chemoembolization (TACE), expanding the range of treatment strategies. At our hospital, balloon-occluded TACE (B-TACE), conventional TACE (C-TACE), and drug-eluting bead TACE (DEB-TACE) have been actively performed for hepatocellular carcinoma (HCC). This study compared the local recurrence-free (LRF) periods of nodules with complete necrosis (TE4) obtained using each treatment method by extracting the nodules evaluated as complete response by the modified Response Evaluation Criteria in Solid Tumors. We performed 580 TACE procedures between June 2013 and April 2019. Among them, 58 HCC nodules in 43 patients, 33 nodules in 30 patients, and 45 nodules in 25 patients were evaluated as having complete necrosis after C-TACE, DEB-TACE, and B-TACE, respectively. The time to local recurrence for each nodule was defined as the LRF period, and the quality of TE4 for each TACE was examined. Factors related to overall survival and the LRF period were determined by univariate and multivariate analyses, and overall survival and the LRF period were analyzed using the Kaplan-Meier method. Multivariate analysis of the LRF period showed that B-TACE was an independent factor. The median LRF periods were 39.3, 13, and 9.1 months for B-TACE, C-TACE, and DEB-TACE, respectively. Moreover, B-TACE had a significantly longer LRF period than C-TACE and DEB-TACE. Conclusion: There was no significant difference between C-TACE and DEB-TACE. The LRF period of nodules with TE4 was the longest with B-TACE, suggesting that B-TACE should be used to achieve a radical cure in patients with HCC.

At the heart of the problem: congestive cardiac failure as a cause of ascites: A narrative review

Heart failure leading to cardiac ascites is an extremely rare and underrecognized entity in clinical practice. Recognizing cardiac ascites can be difficult, especially since patients presenting with ascites may have more than 1 etiology. Various biomarkers are available to aid in the diagnosis of cardiac ascites, though with differing sensitivities and specificities. Such biomarkers include serum albumin, ascitic albumin and protein, as well as serum N-terminal pro-brain natriuretic peptide (NT-proBNP). While serum NT-proBNP is a powerful biomarker in distinguishing the etiology of ascites and monitoring treatment progression, its cost can be prohibitive in low-resource settings. Clinicians practicing under these circumstances may opt to rely on other parameters to manage their patients. We go on further to report a series of 3 patients with cardiac ascites to illustrate how these biomarkers may be employed in the management of this patient population. Clinicians should always keep in mind the differential diagnosis of cardiac failure as a cause of ascites. The resolution of cardiac ascites may serve as a surrogate clinical marker for response to antifailure therapy in lieu of NT-proBNP at resource-scarce centers.

Management of Decompensated Cirrhosis in the Surgical ICU: an American Association for the Surgery of Trauma Critical Care Committee Clinical Consensus Document

Management of decompensated cirrhosis (DC) can be challenging for the surgical intensivist. Management of DC is often complicated by ascites, coagulopathy, hepatic encephalopathy, gastrointestinal bleeding, hepatorenal syndrome, and difficulty assessing volume status. This Clinical Consensus Document created by the American Association for the Surgery of Trauma Critical Care Committee reviews practical clinical questions about the critical care management of patients with DC to facilitate best practices by the bedside provider.

Severe and long-lasting alteration of albumin redox state by plasmapheresis

Plasmapheresis (PE) is an established form of therapeutic apheresis (TA). Purpose of this longitudinal prospective single center study was to investigate the effect of PE on albumin redox state (ARS), as infusion of commercial albumin during PE may alter albumin oxidation which has an impact on its functional properties and oxidative stress level. 43 subjects with autoimmune-mediated neurological disorders were included. 20 subjects in the experimental group received five treatments of PE. 13 subjects received five treatments of immunoadsorption and 10 subjects received no TA as controls. ARS was determined before and after TA and 12 days after the last TA by fractionating it into human mercaptalbumin (HMA), human non-mercaptalbumin 1 (HNA-1), and human non-mercaptalbumin 2 (HNA-2) by high-performance liquid chromatography. Irreversibly oxidised HNA-2 increased over the course of five PE treatments from 2.8% (IQR 1.3–3.7%) to 13.6% (IQR 10.9–15.9) (P < 0.01) and remained elevated 12 days after the last PE procedure (7.7% IQR 7.1–10.5, P < 0.05). The study showed for the first time that PE exerts a severe and long-lasting alteration on ARS indicating a new adverse effect of PE, that may influence oxidative stress level.

Non-Invasive Prediction Models for Esophageal Varices and Red Signs in Patients With Hepatitis B Virus-Related Liver Cirrhosis

Background: Red signs are closely related to esophageal variceal bleeding, and, despite improvements in therapy, the mortality rate remains high. We aimed to identify non-invasive predictors of esophageal varices and red signs in patients with hepatitis B virus-related liver cirrhosis.

Methods: This retrospective study included 356 patients with hepatitis B virus-related liver cirrhosis after applying inclusion and exclusion criteria among 661 patients. All patients underwent endoscopy, ultrasonography, laboratory examinations, and computed tomography/magnetic resonance imaging. Univariate and multivariate logistic regression analysis were performed, and prediction models for esophageal varices and red signs were constructed.

Results: Multivariate analysis revealed that spleen diameter, splenic vein diameter, and lymphocyte ratio were independent risk factors for esophageal varices and red signs. On this basis, we proposed two models: i) a spleen diameter-splenic vein diameter-lymphocyte ratio-esophageal varices prediction model (SSL-EV model); and ii) a spleen diameter-splenic vein diameter-lymphocyte ratio-red sign prediction model (SSL-RS model). The areas under the receiver operating characteristic curve for the two prediction models were 0.843 and 0.783, respectively. With a cutoff value of 1.55, the first prediction model had 81.3% sensitivity and 76.1% specificity for esophageal varices prediction. With a cutoff value of −0.20, the second prediction model had 72.1% sensitivity and 70.7% specificity for the prediction of red signs.

Conclusions: We proposed a new statistical model, the spleen diameter-splenic vein diameter-lymphocyte ratio-red sign prediction model (SSL-RS model), to predict the presence of red signs non-invasively. Combined with the spleen diameter-splenic vein diameter-lymphocyte ratio-esophageal varices prediction model (SSL-EV model), these non-invasive prediction models will be helpful in guiding clinical decision-making and preventing the occurrence of esophageal variceal bleeding.

Risk factors for Fontan-associated hepatocellular carcinoma

Aims

The incidence of hepatocellular carcinoma (HCC) in patients with Fontan-associated liver disease (i.e., FALD-HCC) has increased over time. However, the risk factors for HCC development remain unclear. Here, we compared the levels of non-invasive markers to the survival rate of FALD-HCC patients.

Methods

From 2003 to 2021, 154 patients (66 men, 42.9%) developed liver disease after undergoing Fontan procedures. HCC was diagnosed in 15 (9.7%) (8 men, 53.3%) at a median age of 34 years (range, 21–45 years). We compared FALD-HCC and non-HCC cases; we generated marker level cutoffs using receiver operating characteristic curves. We sought to identify risk factors for HCC and mortality.

Results

The incidence of HCC was 4.9% in FALD patients within 20 years after the Fontan procedure. Compared with non-HCC patients, FALD-HCC patients exhibited higher incidences of polysplenia and esophageal varices. At the time of HCC development, the hyaluronic acid (HA) level (p = 0.04) and the fibrosis-4 index (p = 0.02) were significantly higher in FALD-HCC patients than in non-HCC patients; the total bilirubin (T-BIL) level (p = 0.07) and the model for end-stage liver disease score [excluding the international normalized ratio (MELD-XI)] (p = 0.06) tended to be higher in FALD-HCC patients. Within approximately 20 years of the Fontan procedure, 10 patients died (survival rate, 96.9%). Kaplan–Meier curve analysis indicated that patients with T-BIL levels ≥ 2.2 mg/dL, HA levels ≥ 55.5 ng/mL, and MELD-XI scores ≥ 18.7 were at high risk of HCC, a generally poor prognosis, and both polysplenia and esophageal varices. Multivariate Cox regression analyses indicated that the complication of polysplenia [Hazard ratio (HR): 10.915] and a higher MELD-XI score (HR: 1.148, both p < 0.01) were independent risk factors for FALD-HCC.

Conclusions

The complication of polysplenia and a MELD-XI score may predict HCC development and mortality in FALD patients.

Soluble Urokinase Plasminogen Activator Receptor Levels Are Associated with Severity of Fibrosis in Patients with Primary Sclerosing Cholangitis

The soluble urokinase-type plasminogen activator receptor (suPAR) has evolved as a useful biomarker for different entities of chronic liver disease. However, its role in patients with primary sclerosing cholangitis (PSC) is obscure. We analyzed plasma levels of suPAR in 84 patients with PSC and compared them to 68 patients with inflammatory bowel disease (IBD) without PSC and to 40 healthy controls. Results are correlated with clinical records. suPAR concentrations were elevated in patients with PSC compared to patients with IBD only and to healthy controls (p < 0.001). Elevated suPAR levels were associated with the presence of liver cirrhosis (p < 0.001) and signs of portal hypertension (p < 0.001). suPAR revealed a high accuracy for the discrimination of the presence of liver cirrhosis comparable to previously validated noninvasive fibrosis markers (area under the curve (AUC) 0.802 (95%CI: 0.702−0.902)). Further, we demonstrated that suPAR levels may indicate the presence of acute cholangitis episodes (p < 0.001). Finally, despite the high proportion of PSC patients with IBD, presence of IBD and its disease activity did not influence circulating suPAR levels. suPAR represents a previously unrecognized biomarker for diagnosis and liver cirrhosis detection in patients with PSC. However, it does not appear to be confounded by intestinal inflammation in the context of IBD.

Portopulmonary hypertension and the risk of high right ventricular systolic pressure in liver transplant candidates

Aim

Portopulmonary hypertension (PoPH) is a rare and serious complication of liver cirrhosis and portal hypertension that can interfere with liver transplantation (LT). We evaluated the prevalence of PoPH and the clinical features of right ventricular systolic pressure (RVSP), which is equivalent to pulmonary artery systolic pressure, in LT candidates.

Methods

This was a single-center retrospective study. A total of 157 Japanese patients with decompensated liver cirrhosis or portal hypertension (76 men, median age = 52 years [range: 18–68 years]) were enrolled. The relationships between RVSP and clinical parameters, and the prevalence of PoPH in LT candidates, were evaluated.

Results

The cardiological parameters were as follows: brain natriuretic peptide (BNP), 39.1 (4.0–780.5) pg/mL; RVSP, 31.2 (16.0–122.4) mmHg; ejection fraction, 58% (28–72%); and mean peak tricuspid regurgitation velocity, 2.3 (1.5–5.3) m/s. The RVSP was significantly higher in females (p = 0.02) and primary biliary cholangitis (PBC) patients (p = 0.01), and was weakly correlated with the BNP level (r = 0.40, p = 0.01). For RVSPs of < 36 and ≥ 36 mmHg, the 5-year survival rates were 36.1% versus 34.1%, and 85.4% versus 85.3%, in non-LT and LT cases, respectively (p = 0.47 and 0.69, respectively). Among six patients with an RVSP ≥ 50 mmHg, three (1.9%) were diagnosed with PoPH and treated with vasodilators.

Conclusions

PoPH was observed in 3 cases (1.9%) in 157 LT candidates. In patients with suspected mild pulmonary hypertension (RVSP, 36 - 50 mmHg), LT was successfully performed.

Noninvasive assessment of liver function reserve with fluorescent dosimetry of indocyanine green

Using in vivo multiphoton fluorescent dosimetry, we demonstrate that the clearance dynamics of Indocyanine Green (ICG) in the blood can quickly reveal liver function reserve. In normal rats, the ICG retention rate was below 10% at the 15-minute post-administration; While in the rat with severe hepatocellular carcinoma (HCC), the 15-minute retention rate is over 40% due to poor liver metabolism. With a 785 nm CW laser, the fluorescence dosimeter can evaluate the liver function reserve at a 1/10 clinical dosage of ICG without any blood sampling. In the future, this low-dosage ICG 15-minute retention dosimetry can be applied for the preoperative assessment of hepatectomy or timely perioperative examination.

Development and Validation of a Model for Prediction of End-Stage Liver Disease in People With HIV

BACKGROUND

End-stage liver disease (ESLD) is a leading cause of non-AIDS-related death among people with HIV (PWH). Factors that increase the progression of liver disease include comorbidities and HIV-specific factors, but we currently lack a tool to apply this evidence into clinical practice.

METHODS

We developed and validated a risk prediction model for ESLD among PWH who received care in 12 cohorts of the North American AIDS Cohort Collaboration on Research and Design between 2000 and 2016 and had fibrosis-4 index > 1.45. The first occurrence of ascites, variceal bleed, spontaneous bacterial peritonitis, or hepatic encephalopathy was verified by standardized medical record review. The Bayesian model averaging was used to select predictors among biomarkers and diagnoses and the Harrell C statistic to assess model discrimination.

RESULTS

Among 13,787 PWH in the training set, 82% were men and 54% were Black with a mean age of 48 years. Three hundred ninety ESLD events occurred over a mean 5.4 years. Among the ESLD cases, 52% had hepatitis C virus, 15% hepatitis B virus, and 31% alcohol use disorder. Twelve factors together predicted ESLD risk moderately well (C statistic 0.79, 95% confidence interval: 0.76 to 0.81): age, sex, race/ethnicity, chronic hepatitis B or C, and routinely collected laboratory values reflecting hepatic impairment (serum albumin, aspartate aminotransferase, total bilirubin, and platelets) and lipid metabolism (triglycerides, high-density lipoprotein, and total cholesterol). Our model performed well in the test set (C statistic 0.81, 95% confidence interval: 0.76 to 0.86).

CONCLUSION

This model of readily accessible clinical parameters predicted ESLD in a large diverse population of PWH.

Progress in research of factors associated with esophageal and gastric variceal rebleeding in cirrhosis

Rebleeding of esophageal varices in cirrhosis is the focus of secondary prevention in patients with esophageal varices, which can significantly increase the risk of death and seriously affect the prognosis of patients with cirrhosis. At present, clinical focus is not only on the factors affecting the first bleeding and prognosis of esophageal and gastric varices in cirrhosis, but also on the analysis and summary of the factors related to rebleeding. This paper will summarize the impact of epidemiological and laboratory indexes, endoscopy and imaging, and common scoring systems on rebleeding in liver cirrhosis patients with esophageal varices, with an aim to help clinicians formulate individualized treatment plans and preventive strategies, reduce rebleeding rate and fatality rate, and improve patient prognosis.

Acute-on-chronic liver failure: Epidemiology, prognosis, and outcome of a multicenter study in Thai population

BACKGROUND AND AIM

Acute-on-chronic liver failure (ACLF) leads to multi-organ failure related to high mortality rates. This study aimed to gather epidemiological data and validate a scoring system to predict mortality in ACLF.

METHODS

This retrospective cohort study collected data from multicenter tertiary care hospitals in Thailand. A total of 638 hospitalized patients (acute decompensated liver disease [ADLD], 292 patients; ACLF, 346 patients) from January 2019 to June 2020 were enrolled in this study. We compared the mortality rate at days 30 and 90 between patients with ADLD and ACLF. Areas under the receiver operating characteristic (AUROC) curves of chronic liver failure-sequential organ failure assessment (CLIF-SOFA) and other existing scoring systems were compared among patients with ACLF.

RESULTS

The incidence of patients with ACLF was 54%. The main cause of chronic liver disease was alcohol (38%), with sepsis (50%) as the most common precipitating factor. ACLF with coagulopathy (AUROC 0.58, 95% confidence interval [CI]: 0.52-0.64), metabolic acidosis (AUROC 0.58, 95% CI: 0.52-0.64), and high aspartate aminotransferase (AST) (AUROC 0.59, 95% CI: 0.53-0.66) were associated with high 30-day mortality. The 30-day mortality rate of patients with acute decompensation and patients with ACLF was 46 and 58%, respectively. Respiratory system (P = 0.001) failure was the major end result in ACLF and constituted a significant factor to predict mortality. The AUROC of CLIF-SOFA score was superior to that of the other predicted score (AUROC 0.64, 95% CI: 0.585-0.704).

CONCLUSION

Patients with ACLF with more organ failure and high CLIF-SOFA score were associated with high short-term mortality. Future studies should include an ACLF prospective registry to confirm these finding.

The Significant Morbidity and Mortality Indicators in Patients of Cirrhosis

Background: Cirrhosis progression varies greatly from patient to patient due to a variety of factors, including hepatic reserve, cirrhosis etiology, and the presence of hepatocellular cancer. As a result, determining a prognosis in a patient with cirrhosis remains a difficult task. For nearly three decades, the Child-Pugh score (CPS) has been the gold standard for determining the prognosis of cirrhosis. In the last two decades, many prognostic models and scores like a model for end-stage liver disease (MELD), chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score, peripheral blood lymphocyte to monocyte ratio (LMR) have been presented to predict prognosis in patients with cirrhosis and to choose the best therapy option. The aim of our study is to determine which score is more effective in predicting three-month mortality and whether these scores are equally effective in predicting short-term outcomes.

Materials & methods: In this hospital-based longitudinal study, we analyzed 140 patients with cirrhosis of liver visiting All India Institute of Medical Sciences Bhopal between July 2019 and July 2020. All the 140 patients were followed up for three months to establish short-term outcomes. The blood investigations were done at the time of presentation from all the patients and after three months in the survivors. Various scores were calculated.

Results: The majority of patients (47%) were in Child-Pugh class C. Mean MELD score was 13.54, LMR score was 1.96 and CLIF-SOFA score was 5. The total bilirubin, serum creatinine, international normalized ratio (INR), total leukocyte count, absolute monocyte count, CPS, MELD, CLIF-SOFA were significantly higher in a non-surviving group as compared to the surviving group, whereas the albumin and LMR significantly decreased in the non-surviving group. On performing multivariate regression, LMR and CLIF-SOFA were significant independent risk factors of mortality after adjusting for confounding factors. All the parameters had significant discriminatory power to predict mortality. Discriminatory power of CLIF-SOFA (AUC 0.808; 95% CI: 0.733 to 0.870) was excellent and discriminatory power of CPS (AUC 0.792; 95% CI: 0.716 to 0.856), MELD score (AUC 0.765; 95% CI: 0.685 to 0.832) and LMR (AUC 0.75; 95% CI: 0.669 to 0.819) was acceptable. Among all the parameters, CLIF-SOFA was the best predictor of mortality at a cut-off point of >5 with 80.80% chances of correctly predicting mortality.

Conclusion: The significant morbidity and mortality indicators are high total bilirubin, high creatinine, high INR, high TLC, low platelet count, and low albumin. Among the various scores, CLIF-SOFA is a better predictor of mortality and morbidity. Low LMR and high CLIF-SOFA are significant independent risk factors of mortality at three months.

Association of PD-L1 gene polymorphisms and circulating sPD-L1 levels with HBV infection susceptibility and related liver disease progression

Soluble molecules of programmed death ligand 1 (sPD-L1) are known to modulate T-cell depletion, an important mechanism of hepatitis B virus (HBV) persistence and liver disease progression. In addition, PD-L1 polymorphisms in the 3'-UTR can influence PD-L1 expression and have been associated with cancer risk, although not definitively. The purpose of this study was to investigate the association of PD-L1 polymorphisms and circulating levels of sPD-L1 in HBV infection and live disease progression. In this study, five hundred fifty-one HBV infected patients of the three clinically well-defined subgroups chronic hepatitis B (CHB, n = 186), liver cirrhosis (LC, n = 142) and hepatocellular carcinoma (HCC, n = 223) and 240 healthy individuals (HC) were enrolled. PD-L1 polymorphisms (rs2297136 and rs4143815) were genotyped by in-house validated ARMS assays. Logistic regression models were applied in order to determine the association of PD-L1 polymorphisms with HBV infection as well as with progression of related liver diseases. Plasma sPD-L1 levels were quantified by ELISA assays. The PD-L1 rs2297136 AA genotype was associated with HBV infection susceptibility (HBV vs. HC: OR = 1.6; 95%CI = 1.1-2.3; p = 0.0087) and disease progression (LC vs. CHB: OR = 1.8; 95%CI = 1.1-2.9; p = 0.018). Whereas, the rs2297136 GG genotype was a protective factor for HCC development. Plasma sPD-L1 levels were significantly high in HBV patients (p < 0.0001) and higher in the LC followed by CHB and HCC groups. High sPD-L1 levels correlated with increased liver enzymes and with advanced liver disease progression (Child-pugh C > B > A, p < 0.0001) and BCLC classification (BCLC D > C > B > A, p = 0.031). We could, for the first time, conclude that PD-L1 rs2297136 polymorphism and plasma sPD-L1 protein levels associate with HBV infection and HBV-related liver disease progression.

Value of Liver Function Tests in Cirrhosis

The liver comprises both parenchymal and non-parenchymal cells with varying functions. Cirrhosis is often complicated by the development of portal hypertension and its associated complications. Hence, assessment of liver in cirrhosis should include assessment of its structural, function of both hepatic and non-hepatic tissue and haemodynamic assessment of portal hypertension. There is no single test that can evaluate all functions of liver and assess prevalence and severity of portal hypertension. Commonly available tests like serum bilirubin, liver enzymes (alanine [ALT] and aspartate aminotransferase [AST], serum alkaline phosphatase [ALP], gamma glutamyl transpeptidase [GGT]), serum albumin and prothrombin time for assessment of liver functions partly assess liver functions. quantitative liver functions like indocyanine clearance tests [ICG-K], methacetin breath test [MBT] were developed to assess dynamic status of liver but has its own limitation and availability. Imaging based assessment of liver by transient elastography, MRI based 99 mTc-coupled asialoglycoprotein mebrofenin scan help the clinician to assess liver function, functional volume of liver left after surgery and portal hypertension [PH]. Hepatic venous pressure gradient still remains the gold standard for the assessment of portal hypertension but is invasive and not available in all centres. Combinations of blood parameters in form of various indices like fibrosis score of 4 [FIB-4], Lok index, scores like model for end stage liver disease (MELD) and Child-Turcotte Pugh score are commonly used for assessing liver function in clinical practice.

Systematic review and meta-analysis of risk scores in prediction for the clinical outcomes in patients with acute variceal bleeding

BACKGROUND

Acute variceal bleeding (AVB) is a life-threatening condition that needs risk stratification to guide clinical treatment. Which risk system could reflect the prognosis more accurately remains controversial. We aimed to conduct a meta-analysis of the predictive value of GBS, AIMS65, Rockall (clinical Rockall score and full Rockall score), CTP and MELD.

METHOD

PubMed, Web of Science, Embase, Cochrane library, WANGFANG and CNKI were searched. Twenty-eight articles were included in the study. The Meta-DiSc software and MedCalc software were used to pool the predictive accuracy.

RESULTS

Concerning in-hospital mortality, CTP, AIMS65, MELD, Full-Rockall and GBS had a pooled AUC of 0.824, 0.793, 0.788, 0.75 and 0.683, respectively. CTP had the highest sensitivity of 0.910 (95% CI: 0.864-0.944) with a specificity of 0.666 (95% CI: 0.635-0.696). AIMS65 had the highest specificity of 0.774 (95% CI: 0.749-0.798) with a sensitivity of 0.679 (95% CI: 0.617-0.736). For follow-up mortality, MELD, AIMS65, CTP, Clinical Rockall, Full-Rockall and GBS showed a pooled AUC of 0.798, 0.77, 0.746, 0.704, 0.678 and 0.618, respectively. CTP had the highest specificity (0.806, 95% CI: 0.763-0.843) with a sensitivity of 0.722 (95% CI: 0.628-0.804). GBS had the highest sensitivity 0.800 (95% CI: 0.696-0.881) with a specificity of 0.412 (95% CI: 0.368-0.457). As for rebleeding, no score performed particularly well.

CONCLUSIONS

No risk scores were ideally identified by our systematic review. CTP was superior to other risk scores in identifying AVB patients at high risk of death in hospital and patients at low risk within follow-up. Guidelines have recommended the use of GBS to risk stratification of patients with upper gastrointestinal bleeding. However, if the cause of upper gastrointestinal bleeding is suspected oesophageal and gastric varices, extra care should be taken. Because in this meta-analysis, the ability of GBS was limited.Key messageCTP was superior in identifying AVB patients at high risk of death in hospital and low risk within follow-up.GBS, though recommended by the Guidelines, should be cautiously used when assessing AVB patients.

Ascorbic Acid Deficiency Prevalence and Associated Cognitive Impairment in Alcohol Detoxification Inpatients: A Pilot Study

Malnutrition has been reported in alcohol use disorder patients as having a possible influence on cognitive function. The aim of this study was to analyse the prevalence of ascorbic acid (AA) deficiency in inpatients admitted for alcohol detoxification and the associated factors, including cognitive impairment in the early period of abstinence. A retrospective chart review was conducted. The AA level was categorised into three groups: deficiency (AAD) (<2 mg/L), insufficiency (AAI) (2–5 mg/L) and normal level. The cognitive impairment was screened using the Montreal Cognitive Assessment (MoCA). Ninety-six patients were included (74 men; mean age 49.1 years (±11.5)). Twenty-seven AAD (28.1%) and twenty-two AAI (22.9%) were observed. In multivariate analysis, risk factors for AAD versus normal AA level were men (OR 17.8, 95%CI (1.63–194)), compensated cirrhosis (OR 9.35, 95%CI (1.60–54.6)) and street homelessness (OR 5.76, 95%CI (1.24–26.8) versus personal housing). The MoCA score was available for 53 patients (mean MoCA score: 25.7 (±3.3)). In multivariate analysis, the natural logarithm of AA (β = 1.18, p = 0.037) and sedative use disorder (β = −2.77, p = 0.046) were associated with the MoCA score. AAD and AAI are frequent in inpatients admitted for alcohol detoxification. A low level of AA was associated with cognitive impairment in the early period of abstinence.

Update on blood-based biomarkers for chronic liver diseases prognosis: Literature review and institutional experience

Liver cirrhosis is the final stage of chronic liver disease (CLD) and is associated with high morbidity and mortality. Various complications such as portal hypertension, ascites retention, hepatic encephalopathy, and hepatorenal syndrome deeply affect patient outcome. The most common tools to predict the outcome of a CLD patient include the following: assessing severity of portal hypertension; scoring systems such as the model of end-stage liver disease and Child-Pugh score and blood biomarkers related to complications and/or survival rate. In this article, we summarize recent studies of noninvasive markers for predicting impending complications related to CLD and discuss the clinical value of currently available blood biomarkers based on evidence from the literature. In addition, noninvasive blood biomarker assays for different prognostic functions were validated on 113 liver cirrhosis patients at our institution using Kaplan-Meier curve analysis to confirm that these markers can satisfactorily predict CLD-related patient death.

Risk and protective factors of acute kidney injury in decompensated cirrhotic patients with ascites on tolvaptan

Background and Aim

Acute kidney injury (AKI) is a life‐threatening complication of liver cirrhosis. Here, we evaluated the risk factors and characteristics of AKI in cirrhosis.

Patients/Methods

This was a single‐center retrospective study. A total of 199 Japanese patients with decompensated liver cirrhosis (104 men, median age 61 years) were enrolled and received tolvaptan orally. Survival rates and new onset of AKI were monitored, and risk factors were evaluated.

Results

Forty‐six patients (23.1%) suffered an AKI complication and exhibited significantly poorer survival (P < 0.01). The rates of hepatic encephalopathy (P < 0.01) and chronic kidney disease (CKD; P = 0.02) were significantly increased in patients with AKI. The rate of proton pump inhibitor (PPI)/H2 blocker treatment (P = 0.04) was significantly lower, whereas that of ascites drainage was significantly higher in the AKI cases (P < 0.01). The AKI risk was significantly increased in patients with hepatic encephalopathy (HR 4.18, 95% CI 1.618–10.771). In contrast, the incidence of AKI was significantly lower in patients with a higher serum albumin level (HR 0.36, 95% CI 0.142–0.914, P = 0.03). Treatment with PPI/H2 blockers (HR 0.30, 95% CI 0.126–0.711, P < 0.01) or kanamycin/rifaximin (HR 0.26, 95% CI 0.075–0.929, P = 0.04) was significantly associated with a reduced risk of AKI development.

Conclusions

AKI incidence was increased in patients with decreased liver function and was associated with poor survival. PPI/H2 blocker or kanamycin/rifaximin treatment may reduce the risk of AKI.
