Filter by:The term Acute on chronic liver failure (ACLF) describes a clinical entity characterized by an acute and rapid deterioration of liver function in a patient with previously well-compensated liver disease owing to the effects of a precipitating event. In this condition two insults act simultaneously, one being the preexisting liver injury (chronic liver disease) and the other acute injury which is responsible for the acute decompensation. HEV being a major factor responsible for this clinical entity and has a very high mortality rate. Ribavirin being a safe drug and has been shown to inhibit the replication of HEV, can be an important drug in the treatment of these patients. Therefore the present study is designed to study the impact of Ribavirin in reducing the mortality due to HEV related ACLF.
Hypoxic hepatitis (HH) is reported to be the most frequent cause of elevated aminotransferase levels in hospital. Up to 10 % of critically ill patients develop HH during the course of their intensive care unit (ICU) stay. Occurrence of HH is a life threatening event and ICU-mortality is reported to be up to 60%. Early therapeutic intervention is of central prognostic importance in patients with HH to improve the hemodynamic impairment as early as possible, to reduce hyperammonemia and hepatic encephalopathy, to avoid progression of organ failure and to improve outcome. Studies reported that Molecular Adsorbent Recirculating System (MARS®) therapy improved the hemodynamic situation in patients with acute and acute on chronic liver failure. The study hypothesis is that MARS® therapy in critically ill patients with severe HH improves hepatic hemodynamics and function and consecutively the course of the disease. 40 patients with suffering of severe HH with aminotransferase levels > 40 times the upper limit of normal of more than 12 hours will be randomized 1:1 to MARS® therapy (n=20) or conventional therapy (n=20). 4 MARS®-sessions will be performed on three consecutive days, each for at least 12 hours. Treatment will be continued under special circumstances. The maximum duration of the treatment phase is 7 days. The primary endpoint is the difference of the indocyanine plasma disappearance rate at day 7. The expected duration of the study is 2 years.
The cerebrovascular autoregulation (AR) is impaired in patients with hepatic encephalopathy. Patients with the indication to liver transplantation mostly have mild to severe hepatic encephalopathy. Transplantation should recover the encephalopathy. The aim of the study is to investigate the AR during liver transplantation, with the questions if the AR is impaired at the beginning of surgery and if there are changes in AR. For follow up the AR will be measured at the first days after transplantation at the ICU.
Safety and Efficacy of Everolimus in adult de novo liver transplant recipients.
This is a randomized, open label study evaluating the efficacy and safety of glucocorticoids in patients with HBV associated pre-ACLF. Sponsor: Department of infectious diseases, Southwest Hospital. Indication: HBV associated acute-on-chronic pre-liver failure(pre-ACLF-HBV). Objective: To evaluate the efficacy and safety of glucocorticoids in patients with pre-ACLF-HBV. Trial Design: Randomized, open label study. Patients with pre-ACLF-HBV will be randomized 1:1 to One of the two groups: A)Dexamethasone 10mg were intravenously injected po daily for the first 5 days, in combination with continued lamivudine 100mg po daily and traditional supporting treatments for 13 weeks. B)Control group. Any glucocorticoids will be not given in all patients. Continued lamivudine 100mg po daily and traditional supporting treatments will be given for 13 weeks. Number of patients: Approximate number of patients to be randomized: N=200 (100 patients in each group). Length of study: Screening period: 3 days; treatment period: 13 weeks. Duration of study: 30 months after first patient randomized, including an recruitment period of 26 months. Investigational treated regimen:Dexamethasone 10mg, iv, once day for 5 days. Concomitant and Comparative regimen: Lamivudine 100mg po daily, traditional supporting treatments. Assessments of Efficacy Primary endpoint: the survival rate at week 13. Secondary endpoint:①The levels of serum T-Bil ≤ 51.3µmol/L;②PTA ＞80%. Safety: Adverse events, vital signs, and laboratory tests. Procedures(summary): After signing informed consent and meeting screening parameters, patients will be randomized to one of the two treatment groups as described under trial design above. After randomization patients will be seen for evaluation at days 5,10,14,21,28,42,56,70,84,91. Statistical analysis: Assume 1:1 randomization. The sample size is calculated for the primary efficacy variable, the survival rate. Assuming the survival rate equals to: 90% for group A and 50% for group B. 100 patients in each group are required to yield a 80% chance of detecting such a difference when a two-tailed test is employed at the 0.05 significance levels. Every eligible subject will be assigned with a randomization code and receive one of the two treatments, according to the sequence of enrolled.
Granulocyte colony stimulating factor in acute liver failure and alcoholic hepatitis
Acute liver failure is a rare but dramatic disease, often affecting young people, marked by the sudden loss of liver function in a person without preexisting liver disease. ALF-5755 has been shown to promote cell survival after apoptotic or oxidative stress, and liver cell regeneration in primary cultures and in vivo. ALF-5755 may become, in this dramatic disease with high unmet medical need, a future therapy for the treatment of patients suffering from severe acute hepatitis (SAH) and acute liver failure (ALF) not due to acetaminophen overdose, where liver transplantation is the sole treatment in the absence of spontaneous recovery. The primary objective of the study is to evaluate the efficacy of ALF-5755 versus placebo. A minimum of 60 patients will be recruited into the study in the following two treatment groups: - Group A: approximately 30 patients will receive ALF-5755 - Group B: approximately 30 patients will receive placebo (physiological saline solution: 0.9% NaCl) Patients will receive 10 mg (25 ml) of ALF5755 or placebo every 12 hours over 3 days in slow intravenous infusions over 10 minutes using automatic syringes.
To study the correlation of serological growth factors and the hepatic progenitor cells involved in liver regeneration of liver failure.
Liver failure (LF) is a dramatic clinical syndrome with massive necrosis of liver cells. and liver transplantation is the only available therapeutic option for patients suffering with this condition. However, lack of donors, surgical complications, rejection, and high cost are serious problems. Previous study showed that bone marrow derived mesenchymal stem cells (BM-MSCs) replace hepatocytes in injured liver, and effectively rescue experimental liver failure and contribute to liver regeneration. In this study, the patients with LF will undergo administration of human umbilical cord mesenchymal stem cells (UC-MSCs) via peripheral vein transfusion to evaluate the safty and efficacy of UC-MSCs treatment for these patients.
Patients with acute on chronic liver failure have a risk of developing multiorgan failure and a high mortality. The current scoring systems defining the outcome of patients with acute decompensation of cirrhosis fail to identify patients that progress to Acute-on-chronic liver failure (ACLF). The aim of the study is to evaluate if one can identify these patients early on with the proposed biomarkers: dimethylarginines and ischemia modified albumin.
