Filter by:The clinical trail will assess the safety of miroliverELAP for the treatment of acute liver failure without underlying chronic liver disease. miroliverELAP is an external liver assist combination product consisting of a single-use MIRO-001 bioengineered liver graft and an extracorporeal blood circuit. miroliverELAP Is intended to support the native (failed) liver for up to 48-hours of continuous treatment to allow time for liver recovery or to identify a transplantable liver.
Retrospective evaluation of the value of additive therapeutic plasma exchange (PEX) compared to standard medical therapy (SMT) in Amanita toxin-associated acute liver failure in children and adolescents within the last 10 years at a international group of liver transplant centers.
This will be a study to examine the outcomes of open, laparoscopic, and robotic Living Donor Liver Transplantation (LDLT) procedures. The analysis will encompass 3,448 cases (1,724 donor-recipient pairs) from January 2011 to March 2023, documenting the transition between these surgical techniques, with a noted crossover in 2018.
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 .
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.
This study was a randomized, double-blind, placebo-controlled PhaseⅡ clinical trial . The primary objective of this study was to evaluate the safety of F573 for injection in patients with liver injury (drug-induced liver injury (DILI), chronic hepatitis B (CHB), etc.).
Retrospective chart review will be conducted on patients at Methodist Dallas Medical Center, meeting the inclusion criteria from January 1, 2019 to December 15, 2020 to determine the transplant free survival and overall survival and other secondary outcome measures.
Acute Liver Failure in children is associated with high mortality without liver transplantation. In addition, donor organ shortage makes it difficult to provide this treatment to every potential patient. Liver transplantation is life-saving but it carries the risk of major surgery and complications from lifelong anti-rejection drugs to suppress the immune system. If bridged across the immediate crisis following acute liver failure, the immense regenerative potential of the liver means that the patient's own liver may 're-grow'. This period is very time sensitive. Unfortunately, if the vital synthetic and detoxification function of the liver is not provided, the patient will often die before the liver can re-grow. Transplantation of liver cells (hepatocytes) can provide this 'bridge' with considerable advantages over whole organ transplantation. Firstly, hepatocytes are derived from donor livers which are otherwise unsuitable for transplantation. Secondly, unlike whole organs, they can be frozen and stored, thus act as an 'off the shelf' treatment. Thirdly, the technique of hepatocyte transplantation within microbeads coated with alginate (a gel originating from seaweed) and infused into the abdominal cavity is much less invasive than liver transplantation. Finally, the alginate protects the cells against the body's immune system, avoiding the need for immunosuppressive drugs and the associated major risks. Furthermore, preclinical work in King's College Hospital has shown that the addition of support cells called mesenchymal stromal cells (MSCs), can significantly improve the ability of hepatocytes to survive and function within the alginate microbead. The HELP trial is a Phase 1/2 safety and tolerability study of infusion of HMB002 (an optimal combination of hepatocytes and mesenchymal stromal cells put together in peptide-alginate microbeads) into paediatric patients with acute liver failure. This novel cellular therapy may act as a bridge treatment to liver transplant or lead to regeneration of the native liver.
This project aims to investigate cardiac function in patients with cirrhosis in the acute setting. Acute decompensation and acute-on-chronic liver failure are major events in the life of a patient as they herald disease progression and negative prognosis. Cardiocirculatory function will be assessed by serial assessments in patients admitted for acute decompensation of cirrhosis.
