Filter by:HBV-related acute-on-chronic liver failure (HBV-ACLF) deteriorates rapidly with a high short-term mortality. Early identification and accurate prognostic prediction was critical to improve survival rate. This study was sought to determine the liver volumetry as predictor for short-term mortality in HBV-ACLF and develop a simpler prognostic model based on liver morphology. Liver volumetry were determined from CT at admission. Univariate and multivariate logistic regression were used to identify the optimum prognostic indicators and develop prognostic model. Additionally, receiver operating characteristic curves were analyzed to evaluate the predictive ability of the model.
Acute on chronic liver failure (ACLF) is a distinct entity encompassing the acute deterioration of liver function, culminating in multiple organs failure and high short-term mortality. Definitions and descriptions of ACLF vary between Western and Eastern types, and alcoholism and hepatitis B virus (HBV) are the main etiologies, respectively. To determine whether there are unified diagnostic criteria, severity classification and prognostic model for different etiologies of ACLF. Investigators had launched a multicenter prospective cohort with the same inclusion criteria and disease indicators as those used in the European CANONIC (Chronic liver failure-ACLF in Cirrhosis) study in Chinaļ¼the Ch-CANONIC study(NCT02457637). From Jan 2015 to Dec 2016, 2,600 inpatients with chronic liver disease complicated with ALI and/or AD were recruited. Data were collected during a 28-day hospitalization and continuous follow-ups were performed once a month until 36 months after hospitalization (at least 18 months up to now). Of these patients, 71.5% had HBV-related disease, 1833 had cirrhotic disease, and 767 had non-cirrhotic disease diagnosed by CT scan. Due to the lack of pathological gold standards, the diagnosis of ACLF is based on the clinical assessment of short-term mortality from organ functional parameters. In subsequent statistics and data analysis, investigators focused on (but not limit in) the relationship between short-term mortality and 6 parameters (bilirubin, INR, Creatinine, SpO2/FiO2, mean arterial pressure and West-Haven grade) from CLIF-C OFs (Chronic liver failure-Consortium Organ Failure score). And then a specific mathematical model has been constructed to obtain the available organ failure cutoff values. Subsequently, investigators carried out a diagnostical criteria for ACLF based on the results obtained from the model and get a good internal-validation result through risk ratio. Meanwhile, investigators conducted a precise prediction model for patients' prognosis and achieved a good predictive effect with consistency by AUC internal-validation. In addition, investigators summarized the course and some characteristics of ACLF. Therefore, investigators hope to launch another prospective multi-center cohort study with the same inclusion and exclusion criteria, and continue to recruit 800 to 900 patients (about 30% of the previous cohort) as the external validation cohort for the preliminary results mentioned above.
Background: Acute-on-chronic liver failure (ACLF) is a syndrome characterized by acute deterioration in the setting of chronic liver disease associated with high short-term mortality. Currently, there is no specific treatment for patients with ACLF. Our previous results showed that Chinese herbal medicine (CHM) could reduce the mortality rate and the incidence of complications of ACLF effectively. In this study, we aim to conduct the multi-center randomized controlled trial to evaluate the effect of unified CHM formulas and provide propagable and high-level evidence for clinical practice. Methods/design: This is a prospective, multicenter, centrally randomized controlled trial. Five hundred and ten patients diagnosed with HBV-related ACLF will be allocated in a 1:1 ratio to SMT group (standard medical therapy) and CHM group (CHM and SMT). The primary outcome is the transplant-free mortality rates at week 4, 8, 12, 24 and 48. Secondary outcomes include (1) the incidence of adverse reactions, (2) influence on liver function, (3) the incidence of serious complications and (4) the level of inflammatory cytokines. Discussion: The effectiveness and safety of CHM formulas are assessed in the treatment of ACLF.
The concept of acute-on-chronic liver failure (ACLF) was introduced by Jalan and Williams in 2002 to describe the acute deterioration in liver function over 2 to 4 weeks in a patient with well-compensated cirrhosis associated with a precipitating event (hepatotoxic: superimposed hepatitis viral infection, drug-induced liver injury, hepatotoxins, or excessive alcohol consumption; extra hepatic: variceal bleeding or sepsis), leading to severe deterioration in clinical status with jaundice and hepatic encephalopathy and/or HRS. Following this concept, several proposals for the diagnostic criteria of ACLF have been suggested.
CPFA is currently used in the treatment of severe sepsis with the intention of removing the proinflammatory mediators from the systemic circulation. Some evidence exists about the bilirubin adsorbing ability of the neutral styrenic resin which is part of the extracorporeal circuit of CPFA. The aim of this study is to assess efficacy and safety of CPFA in extracorporeal detoxification of liver toxins in patients affected by acute or acute-on-chronic liver failure.
Ineffective hemostasis or a paradoxical prothrombotic state of Acute-on-chronic liver disease (ACLF) has been well established. Thrombelastography measures the dynamics of thrombin production and provides a global assessment of coagulation incorporating the cumulative effect of the interactions at various levels between plasma components and cellular component of coagulation. And through the platelet mapping, it can help provide a picture of patients' function of platelet. This study aims to explore the predictive role of platelet mapping in ACLF prognosis, organ failure developments and short term mortality.
The definition and diagnostic criteria of Acute-on-chronic liver failure (ACLF) has been well established by EASL CANONIC study. However, patients with high risk to develop ACLF has not been determined, yet. The aim of current study is to establish a preliminary pre-ACLF definition, and to demonstrate the corresponding risk factors.

The First-In-Man study is a multi-centre, randomised, controlled, study to generate data for the evaluation of safety and performance of DIALIVE Liver Dialysis Device in 24 evaluable patients with Acute on Chronic Liver Failure (ACLF) versus standard of care (SOC).
The aim of this study is to assess prospectively the critical period prior to the development of Acute-on-Chronic Liver Failure (ACLF) (1), to uncover mechanistic and pathophysiological processes associated with the development and clinical course of ACLF (2) and to identify the precipitating events of ACLF (3).
