Filter by:This study is a randomized double-blind placebo-controlled multicenter clinical trial to evaluate the safety and efficacy of human umbilical cord mesenchymal stem cell (UC-MSC) transplantation for the treatment of acute-on-chronic liver failure (ACLF). UC-MSC therapy may improve the clinical outcomes of patients with ACLF. The trial would provide scientific evidence for UC-MSC transplantation as a potential treatment for ACLF.
The purpose of this study is to inform healthcare interventions to reduce the disparities in liver transplant listing and in transplantation.
Acute-on-chronic liver failure (ACLF) refers to a liver failure syndrome in which some patients with chronic liver disease with relatively stable liver function suffer from acute liver decompensation and liver failure due to the effects of various acute injury factors，while acute liver failure (ALF) refers to a potentially reversible disorder that was the result of severe liver injury, with an onset of encephalopathy within 8 weeks of symptom appearance and in the absence of pre-existing liver disease. Liver transplantation is the only curative treatment for this type of end-stage liver disease, but the rapid disease progression and lack of donors limit its application. The potential of MSCs to repair or regenerate damaged tissue and suppress immune responses makes them promising in the treatment of liver diseases, especially in the field of liver transplantation. Many studies have shown that MSC-based therapies can reduce the symptoms of liver disease due to their paracrine effects. It has been confirmed in previous studies that infusion of allogeneic MSCs is safe and convenient for patients with ACLF and improve liver function and decrease the incidence of severe infections. Compared to the cells they derive from, mesenchymal stem cells-derived extracellular vesicles (MSC-EVs) are gradually gaining attention for their enhanced safety, as they do not replicate or cause microvascular embolism, and can be easily stored without losing their properties. It represents a novel and effective cell-free therapeutic agent as alternative to cell-based therapies for liver diseases, and liver failure was also concerned. This study was designed to evaluate the safety and efficacy of MSC-EVs in ACLF/ALF .
Acute-on-chronic liver failure (ACLF) refers to the acute deterioration of liver function in patients with chronic liver disease. Neutrophils are a major component of the innate immune system, and previous studies have revealed enhanced production of neutrophil extracellular traps (NETs) in ACLF. However, there is still a lack of systematic research on the correlation between NETs and the prognosis of ACLF. We screened NETs related biomarkers through bioinformatics analysis, which play an important role in the diagnosis of ACLF. This study will explore whether these NETs related biomarkers also play an important role in the prognosis of ACLF and further investigate their role in the pathogenesis of ACLF.
A Phase 2, multi-center, randomized, controlled, open-label study to evaluate the effects of the intraperitoneal, liposomal formulation VS-01 in patients with an acute episode of hepatic and/or extrahepatic organ dysfunctions and failures in the presence of liver cirrhosis (Acute-on-Chronic Liver Failure, ACLF) and accumulation of fluid in the abdominal cavity (ascites)

End-stage liver disease (ESLD) refers to the late stage of liver disease caused by various chronic liver damage. ESLD is an important cause of global incidence rate and mortality, which has a significant impact on the health care system. ESLD is associated with various types of immune dysfunction. The artificial liver support system (ALSS) is an extracorporeal support system that temporarily and partially replaces the partial function of the liver. Its treatment mechanism is to remove all kinds of harmful substances, supplement essential substances, improve the internal environment, create conditions for hepatocyte regeneration and liver function recovery, or use it as a symptomatic support treatment method during the perioperative period of liver transplantation. In this study, we plan to use BS330 for plasma bilirubin adsorption. On this basis, we will add a CA280 cytokine adsorption column to establish a new artificial liver combination model CABA for the immune inflammatory damage mechanism of liver failure.
Hepatic encephalopathy is a frequent complication of both acute liver failure (ALF) and acute-on-chronic liver failure (ACLF) and could be responsible among other neurological complications of residual impairment after liver transplantation. Specific metabolomic studies have shed light into pathophysiology. Nevertheless, whether HE metabolomic fingerprints differ between HE in ALF and HE in ACLF and their evolution after liver transplantation (LT) is unknown. The aim of our study is to analyse the metabolomic fingerprint in plasma of 2 different groups of patients before and after LT: - hospitalized patients with ALF and HE - hospitalized patients with ACLF and HE We will analyse metabolomic results to explore if there is any difference in metabolomic fingerprints between these 2 groups and if LT modify the metabolomic fingerprint in plasma in these 2 groups and in the same way. We will collect blood samples in these 2 groups on the day of HE occurring and then on day 1, day 7 and day 30 (+/- 2 days) after LT. We aim to enroll 10 patients in ALF group and 20 patients in ACLF group. Inclusion criteria are defined as age > 18 years, patient presenting with ALF (Synthetic liver failure (INR > 1.5) with hepatic encephalopathy (grade 1-4 of West-Haven classification), without pre-existing hepatopathy, HE beginning within <26 weeks) or ACLF (≥ grade 1 from CANONIC criteria), and clinical HE (grade 1-4 of West-Haven classification) on the day of enrolment. Exclusion criteria are defined as age < 18 years, absence of HE, LT without pre-existing HE, patients who already undergone a LT, legally protected person. An EDTA blood sample will be collected, centrifuged and frozen on the day of enrolment, then on day 1, day 7 and day 30 (+/- 2 days) after LT. Metabolomic analyses will be performed by different techniques but especially with high resolution liquid phase mass spectrometry in collaboration with CEA. Statistical analyses will be both univariate (Mann-Whitney or Wilcoxon tests) and multivariate (with a classical and adapted method for metabolomic studies: Partial Least-Squares Discriminant Analysis (PLS-DA)). We expect to identify different metabolomic fingerprints between HE in both ALF and ACLF patients as well as different kinetics for symptoms resolution after LT. The long-term objective is to target the specific metabolic pathways for each group in order to allow development of new targeted drugs against HE in these 2 different conditions.
Colon cancer and primary liver cancer are common malignant tumors with low survival rate worldwide, and unresectable primary liver cancer and colon cancer liver metastases have worse prognosis. End-stage liver disease is equated with advanced liver disease, liver failure and decompensated cirrhosis because they are generally irreversible. Liver transplantation is a treatment option for the above-mentioned patients and is expected to improve the prognosis of the patients, but the biggest problem faced by such patients is the shortage of donor livers. Recently, a new surgical modality, resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (RAPID), can greatly alleviate these problems.Based on clinical surgical experience, our center proposes and designs a clinical study of adjuvant liver transplantation combined with two-stage hepatectomy in the treatment of patients with unresectable primary liver cancer, colorectal cancer liver metastases, or end-stage liver disease. By improvement of RAPID operation, the safety and efficacy of this treatment method in patients with those disease were evaluated.
This is a prospective single-center dose escalation study of the administration of the microencapsulated hepatocyte therapy in adult liver failure. The purpose of the study is to determine the maximum tolerated dose of microencapsulated hepatocytes in liver failure patients and its effectiveness in treating the disease.
