Cytokine Adsorption in Acute-on-chronic Liver Failure
Acute-On-Chronic Liver FailureRenal FailureThe CYTOHEP study is a prospective, randomized, single center, open-label, controlled intervention trial to assess the benefit of extracorporeal hemoadsorption using the CytoSorb device in patients with acute-on-chronic liver failure. The primary goal for this trial is to assess whether the CytoSorb device used in addition to continuous renal replacement therapy (CRRT) will be able to significantly reduce bilirubin in the patient blood as compared to the control group treated with CRRT alone (i.e., without extracorporeal hemoadsorption). The rationale for this study is based on considerations about the role of systemic inflammation in acute decompensation of liver cirrhosis and ACLF, in-vitro data of the effectiveness CytoSorb for the removal of molecules with a pathophysiological role in acute-on-chronic liver failure, and recent reports on the successful use of extracorporeal hemoadsorption in combination with CRRT in critically ill patients with acute liver dysfunction.
Study of PD/PK/PG Relationships of Tacrolimus and Cyclosporin in Liver Transplant Patients
End Stage Liver DiseaseRejection4 moreTo search for suitable pharmacodynamic biomarkers, i.e., with high specificity for calcineurin inhibition and most affected by inter-individual variability, our works aimed at exploring the pharmacodynamics of CNI, the strength and variability of signal translation along the calcineurin pathway, as well as the steps where sources of internal (genetic) or external variability are the most influential. In order to achieve this, we assessed simultaneously NFAT1 translocation into the nucleus of peripheral blood mononuclear cells (PBMC) (NFTA1 being the main NAFT isoform in resting and activated lymphocytes), the intracellular expression of IL-2 in CD3+, CD4+ and CD8+ T cell subsets and the membrane expression of CD25 (IL-2Rα), a surface marker of T cells activation, in T cells at large. A non-interventional clinical trial was set up in healthy volunteers, patients registered on a liver transplantation waiting list (WLP) and liver transplant recipients (LTR). A different question was addressed in each group: The healthy volunteer study (n=35): explored TAC PD along the calcineurin pathway by exposing PBMC ex-vivo; modelled signal translation along this cascade; examined the interindividual variability of TAC PD parameters; and investigated the sources of the variability observed and their contribution at each step of the calcineurin pathway. Furthermore, it allowed us to evaluate the analytical variability of our techniques as well as the intra-individual variability of TAC PD parameters. WLP (n=19) were enrolled to confirm in patients with liver diseases the results obtained in healthy volunteers, as well as to test the potential influence of their initial disease on the ex-vivo pharmacodynamics of TAC. The aims of the transversal study of LTR on CNI (n=80) were to further explore the interindividual variability in the PD of CNI in realistic clinical conditions, i.e. in situations of residual PD activities under tacrolimus or cyclosporine exposure, and the potential pharmacogenetic (PG) sources of such variability. The (still small) group of liver transplant patients (n=9) enrolled immediately before transplantation and followed-up with serial monitoring along the first year post-transplantation was intended to explore the relationships between CNI PD and clinical responses.
Safety and Efficacy of Human Autologous Peripheral Blood Stem Cells for Treatment of HBV-related...
Liver CirrhosisEnd Stage Liver DiseaseHBV related Liver disease is a common medical problem in China. An estimated 7.18% of the Chinese (about 93 million) is infected with hepatitis B, and most of the HBV- related hepatitis can developed into liver cirrhosis. Liver transplantation is the only available life saving treatment for patients with end stage liver disease. However, lack of donors, surgical complications, rejection, and high cost are serious problems. In preclinical studies the investigators have demonstrated that G-CSF mobilized PBSC from patients with HBV related liver cirrhosis could differentiate into functional hepatocyte and autologous PBSC transplantation can significantly improve liver synthetic function. But further studied was needed to confirm the safety and efficacy of PBSC transplantation. In this study, a prospective, randomized, parallel clinical study was designed. The patients with HBV-related liver cirrhosis will undergo administration of human autologous PBSCs via hepatic artery to evaluate the safety and efficacy of human autologous PBSCs treatment for these patients.

Acute Liver FailureAcute-On-Chronic Liver FailureThis is a prospective, comparative, open label, phase 2b study designed to investigate the safety and efficacy of LifeLiver (an Extracorporeal Bio Artificial Liver). The study will recruit approximately 40 acute or acute-on-chronic liver failure patients.
Early Postoperative CRRT After Liver Transplantation in ACLF Patients With Overt HE
Acute-On-Chronic Liver FailureHepatic EncephalopathyPretransplant hepatoencephalopathy (HE) markedly impacts recipient outcomes after liver transplantation. Intraoperative CRRT showed benefits but feasibility was much concerned. This study aims to observe the effect on consciousness recovery when initiating CRRT early in the post-transplant period in recipients with ACLF and overt HE.
UC-MSC Infusion for HBV-Related Acute-on-Chronic Liver Failure
Liver FailureHepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) is a severe disease with high mortality. Our previous study have demonstrated that peripheral infusion of bone marrow-derived mesenchymal stromal cells (MSCs) weekly for 4 times is safe and improves 24 weeks survival rate of ACLF patients. In this study, we intend to assess the safety and efficacy of umbilical cord blood derived MSCs for HBV-related ACLF patients.

Liver CirrhosisEnd Stage Liver DiseaseHBV related Liver disease is a common medical problem in China. An estimated 7.18% of the Chinese (about 93 million) is infected with hepatitis B, and most of the HBV- related hepatitis can developed into liver cirrhosis. Liver transplantation is the only available life saving treatment for patients with end stage liver disease. However, lack of donors, surgical complications, rejection, and high cost are serious problems. Mesenchymal stem cells (MSCs) possess plasticity and have the potential to differentiate into hepatocyte; Thus, MSCs hold great hope for therapeutic applications. Human umbilical cord-derived MSCs (hUC-MSCs) exhibit a more beneficial immunogenic profile and greater overall immunosuppressive potential than aged bone marrow-derived MSCs. Like MSCs derived from bone marrow, hUC-MSCs can also be used to treat rat liver fibrosis and improve glucose homeostasis in rats with liver cirrhosis. In this study, the patients with HBV-related liver cirrhosis will undergo administration of hUC-MSCs via hepatic artery to evaluate the safety and efficacy of hUC-MSC treatment for these patients.

Adult bone marrow is the most common source of SCs for clinical applications.Previous study showed that bone marrow derived stem cells (BMSCs) replace hepatocytes in injured liver, and effectively rescue experimental liver failure and contribute to liver regeneration. In this study, the patients with HBV-related liver cirrhosis will undergo administration of human autologous BMSCs via hepatic artery to evaluate the safty and efficacy of human autologous BMSCs treatment for these patients.
Granulocyte Colony Stimulating Factor(G-CSF) Therapy for Patients With ACLF
Acute on Chronic Liver FailureThe purpose of the study is to determine whether Granulocyte Colony Stimulating factor(G-CSF) therapy is effective in the treatment of patients with Acute on chronic liver failure(ACLF). The investigators hypothesize that ACLF is a disease where severe hepatic impairment is accompanied by impaired hepatic regeneration. BMC mobilization using G-CSF therapy, or G-CSF therapy per se would increase the regenerative capacity of the liver and shall lead to clinical, biochemical and histological improvements in patients with ACLF.
