Prevalence of Acute on Chronic Liver Failure in Autoimmune Hepatitis, Treatment Response and Mortality Burden Assessment: A Region-Predominant Systematic Review and Meta-Analysis.

Acute-on-chronic liver failure (ACLF) is a global health problem. Little scientific evidence exists on its prevalence in autoimmune hepatitis. Treatment response and mortality outcomes have also been reported differently. The study was conducted to estimate the overall prevalence of ACLF among patients with autoimmune hepatitis (AIH) and determine the associated treatment response and mortality. We scrutinized wide literature in Scopus, PubMed, Embase, Web of Science, and Cochrane, and assessed published articles completely, studies performed and reported from around the globe, until December 07, 2023, according to the PROSPERO registered protocol (CRD42023412176). Studies (retrospective and prospective cohort study type) that stated the ACLF development among established AIH cases were considered. Features of the study, duration of follow-up, and numeric patient information were retrieved from the studies included. The research paper quality was checked for risk of bias. Random effect meta-analysis with metaregression and subsection scrutinies were performed with R. The main outcome was the collective prevalence of ACLF in the AIH patients, whereas treatment response and mortality in AIH-associated ACLF were secondary outcomes. Six studies were involved with confirmed diagnoses in 985 AIH patients for the data synthesis. The pooled prevalence of ACLF in the explored patients was 12% (95% CI: 8-17) ( P =0.01). Heterogeneity was found to be high in the present meta-analysis ( I2 =72%; P < 0.01). For the secondary endpoint analysis, the pooled prevalence of complete remission at 1-year follow-up was 71% (0.52; 0.85), and mortality from the ACLF-AIH patient population was 32% (95% CI: 18-50). Sensitivity analysis showed no influence on the overall estimations of the pooled prevalence of ACLF by omitting studies one by one. One in 10 AIH patients likely present with ACLF. The response to treatment is seen in two-thirds of patients, and mortality is high.

[Assessment of liver transplant benefit and a novel strategy for liver donor allocation in acute-on-chronic liver failure].

Acute-on-chronic liver failure (ACLF) is a type of complex clinical syndrome that is mainly characterized by acute deterioration of liver function based on chronic liver disease, hepatic and extrahepatic organ failures, and a high short-term mortality rate. The comprehensive medical treatment efficacy of ACLF is currently limited; thus, liver transplantation is the only viable potential treatment method. However, considering the severe liver donor shortage, economic and social costs, as well as the differences in disease severity and prognosis of different disease courses, it is particularly important to accurately assess the benefits of liver transplantation in patients with ACLF. Early identification and prediction, timing, prognosis, and survival benefits are discussed here by combining the latest research findings so as to optimize the liver transplantation treatment strategy for ACLF.

The value of NLR versus MLR in the short-term prognostic assessment of HBV-related acute-on-chronic liver failure.

BACKGROUND: Systemic inflammation is associated with the development and progression of hepatitis B-associated acute-on-chronic liver failure (HBV-ACLF). The neutrophil-to-lymphocyte ratio (NLR) has been reported to be a prognostic biomarker in patients with HBV-ACLF. However, the role of the monocyte-to-lymphocyte ratio (MLR) as a prognostic inflammatory biomarker in multiple diseases is rarely mentioned in HBV-ACLF. METHODS: We included a total of 347 patients with HBV-ACLF who met the definition of the Chinese Guidelines for the Diagnosis and Treatment of Liver Failure (2018 edition). Among them, 275 cases were included retrospectively, and 72 cases were collected prospectively. Clinical characteristics and laboratory examination data were collected from medical records within 24 h after diagnosis to calculate MLR and NLR levels, and lymphocyte subpopulation counts were collected in prospectively included patients. RESULTS: Of the 347 patients with HBV-ACLF, 128 patients in the non-surviving group had a mean age of 48.87 ± 12.89 years; 219 patients in the survival group had a mean age of 44.80 ± 11.80 years and a combined 90-day mortality rate of 36.9%. The median MLR was higher in the non-survivors than in the survivors (0.690 vs 0.497, P < 0.001). MLR values were significantly associated with 90-day mortality in HBV-ACLF (OR 6.738; 95% CI 3.188-14.240, P < 0.001). The AUC for the predictive power of the combined MLR and NLR analysis for HBV-ACLF was 0.694, and the calculated MLR threshold was 4.495. In addition, in the analysis of peripheral blood lymphocyte subsets in HBV-ACLF, a significant decrease in the number of circulating lymphocytes was found in HBV-ACLF patients in the non-surviving group (P < 0.001), with a predominant decrease in the number of CD8 + T cells and no significant difference in the number of CD4 + T cells, B cells or NK cells. CONCLUSION: Increased MLR values are associated with 90-day mortality in patients with HBV-ACLF, and the MLR may serve as a potential prognostic indicator for patients with HBV-ACLF. Decreased CD8 + T-cell counts may be associated with poor survival in patients with HBV-ACLF.

Development of a novel prognostic assessment model for hepatitis B virus-related acute-on-chronic liver failure based on reexamination results.

Acute-on-chronic liver failure (ACLF) is a common clinical emergency and critical illness with rapid progression and poor prognosis. This study aims to establish a more efficient system for the prognostic assessment of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), which will provide a guiding scheme for subsequent treatment and improve the survival rate of patients. Data on 623 patients with HBV-ACLF were recorded. Univariate and multivariate analyses were performed to determine the discriminative abilities of the novel prognostic assessment model in predicting 90-day mortality. The area under the receiver operating characteristic curve was used to evaluate the accuracy of the models. Patients were divided into high- and low-scoring groups based on the best critical values, and survival rates were analyzed using Kaplan-Meier survival analysis and compared by applying log-rank tests. The area under the curve of the new scoring system established using the results of the first reexamination, the results of the first examination, the mean daily change in these results (MDCR) and the results of other first examinations were 0.911 (95% confidence interval [CI]: 0.889, 0.933), 0.893 (95% CI: 0.868, 0.917), and 0.895 (95% CI: 0.871, 0.919), respectively. The final prognostic scoring system established using the results of the first reexamination was chosen as a novel prognostic assessment model, and patients with lower scores (first reexamination results [FRER] score ≤ 3.65) had longer survival times (P < .001). The prognostic scoring system established using the FRER combined with other examination results can better assess the prognosis of HBV-ACLF at 90 days.

[Assessment Value of Short-Term Prognosis of Six Predictive Models for Patients with Acute-on-Chronic Liver Failure Treated with Artificial Liver Support System].

Objective: To apply 6 predictive models on acute-on-chronic liver failure (ACLF) patients treated with artificial liver support system (ALSS), and to compare their assessment values for the short-term prognosis of patients. Methods: A total of 258 ACLF patients who underwent ALSS therapy between January 2018 and December 2019 were selected from the ALSS clinical database established by West China Hospital, Sichuan University, and their clinical data and 90-day prognosis information were collected. Cox proportional hazards model was used to estimate the association between the six predictive models, including Chinese Group on the Study of Severe Hepatitis B-ACLF (COSSH ACLF), European Association for the Study of the Liver--Chronic Liver Failure-Consortium (CLIF-C) ACLF, CLIF-C Organ Failure (OF), Asian Pacific Association for the Study of the Liver (APASL) ACLF Research Consortium (AARC) ACLF, Model for End-Stage Liver Disease (MELD) and Simplified MELD (sMELD), and 90-day mortality, which included death or receiving liver transplantation. The area under the receiver operating characteristic (ROC) curve ( AUC), Harrell's C-index and Brier scores were calculated and compared to evaluate the predictive power. Results: A total of 258 ACLF patients were enrolled. Of these patients, who had a mean age of (46.2±11.7) years old, 37 (14.3%) patients were female, 202 (78.3%) patients had a diagnosis of liver cirrhosis, and 107 (41.5%) patients died during the 90-day follow-up period. The six predictive models all yielded higher scores for patients who died than those for patients who survived (all P<0.001). The six predictive models were all independent risk factors for the short-term prognosis of ACLF patients treated with ALSS (all adjusted hazard ratio [HR]>1, all P<0.001). The AUC (0.806, 95% confidence interval [CI]: 0.753-0.853) and Harrell's C-index (0.772, 95% CI: 0.727-0.816) of COSSH ACLF were much higher than those of the five other predictive models (all AUCs<0.750, P<0.01; all Harrell's C-indices<0.750, P<0.001). The Brier score of COSSH ACLF was 0.18 (95% CI: 0.15-0.20). The 90-day mortality of patients defined as having low risk, moderate risk, and high risk according to the risk stratification of COSSH ACLF were 22.2%, 56.3%, and 90.2%, respectively. Conclusion: The COSSH ACLF could more accurately predict short-term prognosis in ACLF patients who received ALSS therapy, and could facilitate clinical decision-making.

The assessment of mesenchymal stem cells therapy in acute on chronic liver failure and chronic liver disease: a systematic review and meta-analysis of randomized controlled clinical trials.

BACKGROUND: Mesenchymal stem cells (MSCs) therapy is showing potential therapeutic effects on liver function improvement in patients with chronic liver disease; however, the consensus on efficacy and safety of MSCs has not been reached. METHODS: We performed this systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy and safety of MSCs therapy for patients with chronic liver disease. A detailed search of the Cochrane Library, MEDLINE, Web of Science, and EMBASE databases was conducted to find studies published prior to September 15, 2021. The outcome measures were survival rate, model of end-stage liver disease (MELD) score, albumin, total bilirubin, coagulation function, and aminotransferase. RESULTS: A literature search resulted in 892 citations. Of these, 12 studies met the inclusion criteria. It was found that compared with conventional treatment, MSCs therapy was associated with improved liver function including the MELD score, albumin levels, and coagulation function. However, it had no obvious beneficial effects on survival rate and aminotransferase levels. Subgroup analyses indicated that MSCs therapy had therapeutic effects on patients with both acute on chronic liver failure (ACLF) and cirrhosis. BM-MSCs and UC-MSCs treatment had similar efficacy to improve liver function. The effectiveness varied slightly between the peripheral intravenous injection and hepatic arterial injection. Five studies reported that the only adverse event of the MSCs therapy was fever, and no serious adverse events and side effects were reported. Analysis on clinical symptoms showed that encephalopathy and gastrointestinal hemorrhage events were reduced after MSCs therapy. CONCLUSIONS: In conclusion, this study suggested that MSCs therapy could be a potential therapeutic alternative for patients with chronic liver disease in clinical practice.

Comparison of tenofovir alafenamide and entecavir for hepatitis B virus-related acute-on-chronic liver failure. / å¯Œé©¬é ¸ä¸™é šæ›¿è¯ºç¦éŸ¦ä¸Žæ©æ›¿å¡éŸ¦æ²»ç–—ä¹™åž‹è‚ç‚Žç— æ¯’ç›¸å ³æ ¢åŠ æ€¥æ€§è‚è¡°ç«­çš„æ•ˆæžœå¯¹æ¯”.

OBJECTIVES: Hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) is the most common type of liver failure in China, with a high mortality. Early rapid reduction of HBV-DNA load can improve the survival rate of HBV-ACLF patients. At present, the commonly used drugs are nucleoside (acid) analogues, such as entecavir (ETV), tenofovir, and so on. The newly listed tenofovir alafenamide fumarate (TAF) has attracted great attention of clinicians because of its stronger antiviral effect, higher transaminase normalization rate, better bone and kidney safety, and zero drug resistance. However, there are few clinical research data on the efficacy and safety of TAF in the treatment of Chinese HBV-ACLF patients, and there is a lack of pharmacoeconomic evaluation. This study aims to compare the efficacy, safety, and cost-effectiveness between TAF and ETV in patients with HBV-ACLF. METHODS: The data were collected from 196 HBV-ACLF patients (80 patients in the TAF group and 116 patients in the ETV group) who were hospitalized in Xiangya Hospital, Central South University from May 2020 to March 2021. Biochemistry and virology were detected before and after treatment (at baseline, Week 2, 4, and 12). Clinical features, disease prognosis, and cost-effectiveness were compared between the 2 groups. According to the baseline, HBV-ACLF patients were divided into 4 stages including pre-liver failure stage, early stage, medium stage, and end stage. And the liver transplantation rate and mortality was also compared. Pharmacoeconomic evaluation was taken using cost-effectiveness analysis and cost minimization analysis．. RESULTS: After 4 weeks of treatment, there were no significant differences in the efficacy (liver function, viral load) between the 2 groups (all P>0.05). The TAF group showed lower creatinine [(80.35±18.77) µmol/L vs (105.59±82.32) µmol/L, P<0.05] and higher estimated glomerular filtration rate (eGFR) levels [(95.65±23.21) mL/(min·1.73 m2) vs (82.68±26.32) mL/(min·1.73 m2), P<0.05] than the ETV group. After 12 weeks of treatment, the analysis of overall the liver transplantation rate and mortality between the 2 groups showed similar conclusion. However, the TAF group had a lower the liver transplantation rate and mortality than the ETV group in patients with pre-liver failure (0vs13.89%, P<0.05). No evident distinction was found in the liver transplantation rate and mortality during the early, medium, or end stages of liver failure (13.04% vs 17.65%, 37.50% vs 37.04%, and 54.55% vs 68.42%, respectively). Ratio of cost to effectiveness in the ETV group was higher than that in the TAF group. CONCLUSIONS: TAF is not more efficient than ETV group in improving liver function and reducing viral load for HBV-ACLF patients and they also show similar safety. However, TAF has a greater advantage over ETV not only in preserving renal function, but also in reducing the liver transplantation rate and mortality in patients with pre-liver failure. TAF can provide economic benefit to patients with HBV-ACLF.

Global burden of disease: acute-on-chronic liver failure, a systematic review and meta-analysis.

BACKGROUND AND AIMS: Acute-on-chronic liver failure (ACLF) is characterised by acute decompensation of cirrhosis associated with organ failures. We systematically evaluated the geographical variations of ACLF across the world in terms of prevalence, mortality, aetiology of chronic liver disease (CLD), triggers and organ failures. METHODS: We searched EMBASE and PubMed from 3/1/2013 to 7/3/2020 using the ACLF-EASL-CLIF (European Association for the Study of the Liver-Chronic Liver Failure) criteria. Two investigators independently conducted the abstract selection/abstraction of the aetiology of CLD, triggers, organ failures and prevalence/mortality by presence/grade of ACLF. We grouped countries into Europe, East/South Asia and North/South America. We calculated the pooled proportions, evaluated the methodological quality using the Newcastle-Ottawa Scale and statistical heterogeneity, and performed sensitivity analyses. RESULTS: We identified 2369 studies; 30 cohort studies met our inclusion criteria (43 206 patients with ACLF and 140 835 without ACLF). The global prevalence of ACLF among patients admitted with decompensated cirrhosis was 35% (95% CI 33% to 38%), highest in South Asia at 65%. The global 90-day mortality was 58% (95% CI 51% to 64%), highest in South America at 73%. Alcohol was the most frequently reported aetiology of underlying CLD (45%, 95% CI 41 to 50). Infection was the most frequent trigger (35%) and kidney dysfunction the most common organ failure (49%). Sensitivity analyses showed regional estimates grossly unchanged for high-quality studies. Type of design, country health index, underlying CLD and triggers explained the variation in estimates. CONCLUSIONS: The global prevalence and mortality of ACLF are high. Region-specific variations could be explained by the type of triggers/aetiology of CLD or grade. Health systems will need to tailor early recognition and treatment of ACLF based on region-specific data.

Diagnósticos de enfermagem em pacientes com cirrose hepática em um serviço hospitalar de emergência / Nursing diagnoses in patients with liver cirrhosis in an emergency hospital service

Introdução: O estudo foi desenvolvido com o intuito de destacar a importância dos diagnósticos de enfermagem em pacientes cirróticos, em decorrência do aumento de casos de doenças hepáticas. Objetivo: Descrever as variáveis sociodemográficas e clínicas e elencar os diagnósticos de enfermagem da Associação Norte-Americana de Diagnósticos de Enfermagem (NANDA-I) em pacientes com cirrose hepática atendidos em uma emergência hospitalar. Material e Métodos: Pesquisa quantitativa, descritiva e transversal, realizada com 59 pacientes atendidos em uma emergência de um hospital universitário no sul do Brasil, no período de abril a junho de 2018. Resultados: Prevaleceu durante a pesquisa a população do sexo masculino com 66,1% e de baixo nível educacional, tendo o álcool como principal etiologia da doença com 44,1% e a presença de comorbidades como a hipertensão com 14,8% e o diabetes com 15,6%. Foram identificados seis diagnósticos de enfermagem com maior prevalência: risco de infecção, risco de desequilíbrio eletrolítico, nutrição desequilibrada (menor do que as necessidades corporais), dor aguda, volume de líquidos excessivo e risco de sangramento. Conclusão: As características sociodemográficas apresentadas neste estudo corroboram os achados já amplamente conhecidos em doença hepática. Os diagnósticos de enfermagem identificados foram condizentes com as repercussões fisiopatológicas da cirrose hepática, destacando-se o predomínio dos diagnósticos de risco.

Introduction: The study was developed with the aim of highlighting the importance of nursing diagnoses in cirrhotic patients, due to the increase in cases of liver disease. Objective: Describe the sociodemographic and clinical variables and list the nursing diagnoses of the North American Association of Nursing Diagnoses (NANDA-I) in patients with liver cirrhosis treated in a hospital emergency. Material and Methods: Quantitative, descriptive and cross-sectional research, conducted with 59 patients seen in an emergency department of a university hospital in southern Brazil, from April to June 2018. Results: There was a predominance during the research of the male population with 66.1% and of low educational level, with approximately 54.2% having completed elementary school, with alcohol as the main etiology of the disease with 44.1% and the presence of comorbidities such as hypertension with 14.8% and diabetes with 15.6%. Six nursing diagnoses with higher prevalence were identified: risk of infection, risk of electrolyte imbalance, unbalanced nutrition (less than body needs), acute pain, excessive fluid volume and risk of bleeding. Conclusion: The sociodemographic characteristics presented in this study corroborate the already widely known findings in liver disease. The nursing diagnoses identified were consistent with the pathophysiological repercussions of liver cirrhosis, highlighting the predominance of risk diagnoses.

'Equity' and 'Justice' for patients with acute-on chronic liver failure: A call to action.

Acute-on-chronic liver failure (ACLF) occurs in hospitalised patients with cirrhosis and is characterised by multiorgan failures and high rates of short-term mortality. Without liver transplantation (LT), the 28-day mortality rate of patients with ACLF ranges from 18-25% in those with ACLF grade 1 to 68-89% in those with ACLF grade 3. It has become clear that patients with ACLF do not have equitable access to LT because of current allocation policies, which are based on prognostic scores that underestimate their risk of death and a lack of appreciation of the clear evidence of transplant benefit in carefully selected patients (who can have excellent post-LT outcomes). In this expert opinion, we provide evidence supporting the argument that patients with ACLF should be given priority for LT based on prognostic models that define the risk of death for these patients. We also pinpoint risk factors for poor post-LT outcomes, identify unanswered questions and describe the design of a global study, the CHANCE study, which will provide answers to the outstanding issues. We also propose the worldwide adoption of new organ allocation policies for patients with ACLF, as have been initiated in the UK and recommended in Spain.

Limitations of current liver donor allocation systems and the impact of newer indications for liver transplantation.

Liver transplantation represents a life-saving treatment for patients with decompensated cirrhosis, a severe condition associated with a high risk of waiting list mortality. When decompensation occurs rapidly in the presence of extrahepatic organ failures, the condition is called acute-on-chronic liver failure, which is associated with an even higher risk of death, though liver transplantation can also markedly improve survival in affected patients. However, there are still gaps in our understanding of how to optimise prioritisation and organ allocation, as well as survival among patients with acute-on-chronic liver failure (both before and after transplant). Moreover, it is urgent to address inequalities in access to liver transplantation in patients with severe alcoholic hepatitis and non-alcoholic steatohepatitis. Several controversies still exist regarding gender and regional disparities, as well as the use of suboptimal donor grafts. In this review, we aim to provide a critical perspective on the role of liver transplantation in patients with decompensated cirrhosis and address areas of ongoing uncertainty.

Point-of-Care Echocardiography and Hemodynamic Monitoring in Cirrhosis and Acute-on-Chronic Liver Failure in the COVID-19 Era.

Point-of-Care (POC) transthoracic echocardiography (TTE) is transforming the management of patients with cirrhosis presenting with septic shock, acute kidney injury, hepatorenal syndrome and acute-on-chronic liver failure (ACLF) by correctly assessing the hemodynamic and volume status at the bedside using combined echocardiography and POC ultrasound (POCUS). When POC TTE is performed by the hepatologist or intensivist in the intensive care unit (ICU), and interpreted remotely by a cardiologist, it can rule out cardiovascular conditions that may be contributing to undifferentiated shock, such as diastolic dysfunction, myocardial infarction, myocarditis, regional wall motion abnormalities and pulmonary embolism. The COVID-19 pandemic has led to a delay in seeking medical treatment, reduced invasive interventions and deferment in referrals leading to "collateral damage" in critically ill patients with liver disease. Thus, the use of telemedicine in the ICU (Tele-ICU) has integrated cardiology, intensive care, and hepatology practices across the spectrum of ICU, operating room, and transplant healthcare. Telecardiology tools have improved bedside diagnosis when introduced as part of COVID-19 care by remote supervision and interpretation of POCUS and echocardiographic data. In this review, we present the contemporary approach of using POC echocardiography and offer a practical guide for primary care hepatologists and gastroenterologists for cardiac assessment in critically ill patients with cirrhosis and ACLF. Evidenced based use of Tele-ICU can prevent delay in cardiac diagnosis, optimize safe use of expert resources and ensure timely care in the setting of critically ill cirrhosis, ACLF and liver transplantation in the COVID-19 era.

Noninvasive assessment of liver fibrosis for predicting acute-on-chronic liver failure in patients with chronic hepatitis B.

BACKGROUND AND AIM: The aim of this study was to evaluate the accuracy of serum markers of liver fibrosis for predicting progression to acute-on-chronic liver failure (ACLF) in patients with acute exacerbation (AE) and severe AE (SAE) of chronic hepatitis B virus (HBV) infection. METHODS: The predictive accuracy of aminotransferase-to-platelet ratio index (APRI), Fibrosis-4, Lok index, and Forns index for progression to ACLF was evaluated via receiver operating characteristic (ROC) curve and area under the ROC (AUROC) in 441 and 130 patients with AE and SAE. RESULTS: After admission, 24 (5.8%) and 25 (19.2%) patients with AE and SAE, respectively, progressed to ACLF. The Lok index was one of the independent risk factors associated with progression to ACLF in patients with AE and SAE. The AUROC of Lok index for diagnosing liver cirrhosis was 0.815 (0.774-0.851) in patients with AE and 0.715 (0.629-0.791) in patients with SAE. The AUROC of Lok index for predicting progression to ACLF in patients with AE and SAE was 0.756 (0.711-0.797) and 0.866 (0.795-0.919), respectively. In patients with AE and SAE, the cut-off values of the Lok index for predicting ACLF were higher and lower, respectively, than those for diagnosing liver cirrhosis. CONCLUSION: The Lok index has predictive accuracy regarding progression to ACLF in patients with AE and SAE. Different thresholds of liver fibrosis are needed for determining progression to ACLF in patients with different severity of liver injury during acute exacerbation of chronic HBV infection.

Increased access to liver transplantation for patients with acute on chronic liver failure after implementation of Share 35 Rule: An analysis from the UNOS database.

INTRODUCTION AND OBJECTIVES: Acute on chronic liver failure (ACLF), leads to high mortality. These patients are at risk of being delisted for liver transplantation (LT). Emerging data shows 1y post-transplant survival of 80-92%. The Share 35 (S35) policy was implemented to prioritize patients with MELD ≥35 on the LT waitlist. Our aim was to compare the LT outcomes of ACLF patients as a result of S35. MATERIALS AND METHODS: Data from the UNOS scientific registry were used to classify ACLF patients using the NACSELD criteria. For the analyses, data were divided into two eras; 2 years before S35 (Era 1) and 2 years after S35 (Era 2). Waitlist status was classified into categories: Transplanted, Death or Too Sick to Transplant and Still Waiting/Other. LT cumulative incidence between the populations in the eras was calculated using Fine and Gray's method. A proportional hazards model was used to investigate the era effect on cumulative incidence of LT. RESULTS: 46,861 patients were reviewed, of which 817 had ACLF. 366 patients (mean MELD: 37.1) were identified in Era 1 and 451 patients (mean MELD: 37.3) in Era 2. We found that ACLF patients were more likely to receive a liver transplant in Era 2 (p=0.0074). In both eras, transplanted patients had a significantly higher survival than those who were not transplanted (p<0.0001). CONCLUSIONS: Our study shows that S35 improved LT rate for ACLF suggesting that there should be broader recognition of ACLF and early transplantation should be pursued.

[Influence of a spontaneous bacterial peritonitis, nosocomial infections and acute-on-chronic liver failure on treatment revenues in patients with decompensated cirrhosis in Germany]. / Einfluss einer spontan bakteriellen Peritonitis, nosokomialer Infektionen und eines akut auf chronischen Leberversagens auf die Behandlungserlöse bei Patienten mit dekompensierter Leberzirrhose in Deutschland.

BACKGROUND: The economic effects of spontaneous bacterial peritonitis (SBP), nosocomial infections (nosInf) and acute-on-chronic liver failure (ACLF) have so far been poorly studied. We analyzed the impact of these complications on treatment revenues in hospitalized patients with decompensated cirrhosis. METHODS: 371 consecutive patients with decompensated liver cirrhosis, who received a paracentesis between 2012 and 2016, were included retrospectively. DRG (diagnosis-related group), "ZE/NUB" (additional charges/new examination/treatment methods), medication costs, length of hospital stay as well as different kinds of specific treatments (e. g., dialysis) were considered. Exclusion criteria included any kind of malignancy, a history of organ transplantation and/or missing accounting data. RESULTS: Total treatment costs (DRG + ZE/NUB) were higher in those with nosInf (€â€Š10,653 vs. €â€Š5,611, p < 0.0001) driven by a longer hospital stay (23 d vs. 12 d, p < 0.0001). Of note, revenues per day were not different (€â€Š473 vs. €â€Š488, p = 0.98) despite a far more complicated treatment with a more frequent need for dialysis (p < 0.0001) and high-complex care (p = 0.0002). Similarly, SBP was associated with higher total revenues (€â€Š10,307 vs. €â€Š6,659, p < 0.0001). However, the far higher effort for the care of SBP patients resulted in lower daily revenues compared to patients without SBP (€â€Š443 vs. €â€Š499, p = 0.18). ACLF increased treatment revenues to €â€Š10,593 vs. €6,369 without ACLF (p < 0.0001). While treatment of ACLF was more complicated, revenue per day was not different to no-ACLF patients (€â€Š483 vs. €â€Š480, p = 0.29). CONCLUSION: SBP, nosInf and/or ACLF lead to a significant increase in the effort, revenue and duration in the treatment of patients with cirrhosis. The lower daily revenue, despite a much more complex therapy, might indicate that these complications are not yet sufficiently considered in the German DRG system.

Rotational thrombelastometry (ROTEM) improves hemostasis assessment compared to conventional coagulation test in ACLF and Non-ACLF patients.

BACKGROUND: Patients with liver cirrhosis typically exhibit abnormal coagulation parameters in conventional coagulation tests (CCTs). Rotational thromboelastometry (ROTEM) is a holistic blood coagulation assay. This method provides an insight into the global hemostatic capabilities and has been suggested to provide a better overview of the coagulation system in liver cirrhosis. METHODS: The goal of this study was to examine hemostasis in patients with stable liver cirrhosis (Non-ACLF) and in acute-on-chronic liver failure (ACLF) by CCT and ROTEM including agreement of both tests and the prospective assessment of test performance based on clinical outcomes in ACLF patients. Therefore, ACLF patients were additionally subgrouped by bleeding events. Fifty-five Non-ACLF patients and twenty-two patients with ACLF were analysed in this prospective cohort study. RESULTS: Coagulation parameters analysed by CCT were outside the normal range in Non-ACLF and ACLF patients, but were significantly more aberrant in ACLF patients. Non-ACLF patients analysed by ROTEM revealed parameters largely within the normal limits, while significantly more ROTEM parameters in ACLF patients were affected. Maximum clot firmness (MCF) was significantly divergent between both patient groups and correlated well with levels of fibrinogen and platelet count. Using Cohen's Kappa coefficient κ, the strength of agreement between CCT and ROTEM analyses was determined to be fair for Non-ACLF patients and moderate for ACLF patients. Bleeding events occurred significantly more often in ACLF group with significantly reduced A10 and MCF. CONCLUSIONS: For assessing hemostasis in Non-ACLF and ACLF patients the underlying dataset shows advantages of ROTEM over CCT. A10 and MCF represent suitable prognostic parameters in predicting bleeding events in ACLF group.

Increasing Burden of Acute-On-Chronic Liver Failure Among Alcohol-Associated Liver Disease in the Young Population in the United States.

OBJECTIVES: Alcohol-associated liver disease is increasing, especially hospitalizations with acute on chronic liver failure and need for liver transplant. We examined trends in prevalence, inhospital mortality, and resource utilization associated with AALD and ACLF in the young. METHODS: The National Inpatient Sample (2006-2014) was queried for hospitalizations with a discharge diagnosis of cirrhosis using the International Classification of Diseases, Ninth Edition, codes. ACLF hospitalization was defined as ≥2 organ failures and stratified by age: young (≤35 years) and older (>35 years). RESULTS: Of 447,090 AALD admissions (16,126 in young) between 2006 and 2014, ACLF occurred in 29,599 (6.6%), of which 1,143 (7.1%) were in young. Compared with older, admissions in young had more women (35% vs 29%), were obese (11% vs 7.6%), were Hispanics (29% vs 18%), have alcoholic hepatitis (AH) (41% vs 17%), and have ACLF grades 2 or 3 (34% vs 25%), P < 0.001 for all. Between 2006 and 2014, ACLF in AALD among young increased from 2.8% to 5.2%, with an AH proportion from 24% to 42%, P < 0.0001 for both. Young had more complications requiring ventilation (79% vs 76%) and dialysis (32% vs 28%), P < 0.001 for both. Compared with older, ACLF admission in young had longer hospitalization (12 vs 10 days) with higher hospital charges ($127,915 vs $97,511), P < 0.0001 for both, with 20% reduced inhospital mortality (54%-45%), P < 0.001. DISCUSSION: AALD-related hospitalizations are increasing in young in the United States, mainly because of the increasing frequency of AH. Furthermore, this disease burden in young is increasing with a higher frequency of admissions with more severe ACLF and consumption of hospital resources. Studies are needed to develop preventive strategies to reduce burden related to AALD and ACLF in young.
