Active clinical trials for "Liver Cirrhosis"

The objective of this study is to evaluate the therapeutic efficacy of Infrared ray heat treatment in hepatic area in cirrhosis patients with refractory ascites. The evaluation of the efficacy includes the ascites pressure, portal vein velocity，SAAG before and after the treatment. Clinical symptoms were also observed simultaneously.

Liver fibrosis is the most serious complication of schistosomiasis mansoni. However only limited proportion of subjects with infection develop this pathology and there is limited knowledge on risk factors for the differential morbidity patterns observed in endemic communities. Our preliminary cross-sectional study indicated that serum levels of antioxidants may be related with the development of fibrosis. The present project is a randomised double blinded placebo controlled prospective study investigating the role of food based antioxidant supplements on the outcome of anti-schistosomal chemotherapy with regards to the extent of fibrosis reversal.

Cirrhosis is caused by sustained liver damage over several years either by alcohol, viral infection (Hepatitis B, C), a toxic substance (for eg. drugs, excess copper or iron in the liver), or by blockage of biliary system such that the liver undergoes progressive scarring that slowly replaces all of normal liver cells.(LC) represents a late stage of progressive hepatic fibrosis characterized by distortion of the hepatic architecture and formation of regenerative nodules. For this condition of disease the liver transplantation is one of the only effective therapies available ,but due to lack of donors, surgical complications, rejection, and high cost are it's serious problems. Presently stem cells are used to be a one of the treatment for the same. So our approach is to evaluate the safety and efficacy of mesenchymal stem cell in condition of liver cirrhosis .

The aim of the study is to choose an optimal stent and to get further knowledge about the mechanisms of the engraftment of a stent. The occurrence of a hyperplasia of neointima can be minimized by application of a coated stent and a concurrent safety four weekly dual thrombocytes therapy

The primary biliary cholangitis (PBC), formerly known as primary biliary cirrhosis, treatment is based in the use of ursodeoxycholic acid (UDCA) at a daily dose of 13 to 15 mg/kg, without other treatment options. Patients with good or complete response to UDCA have more liver transplant-free survival and delay histologic progression compared to patients with partial or no response. Nowadays there is an estimated partial response to UDCA in approximately 30 to 50% of patients with PBC. There is a need for new second line management strategies for patients without a biochemical response to UDCA. The addition of bezafibrate to the treatment of PBC patients with partial biochemical response to UDCA, will increase the biochemical response and improve the long term prognosis? And if so, which are the efficacy and security of bezafibrate in PBC patients without biochemical response?

Recently it has been acknowledged that cirrhotic patients present with "rebalanced hemostasis" that results from decreased levels of both pro-coagulant and anti-coagulant factors, that is not well reflected by conventional coagulation tests (CCTs). Thromboelastography (TEG) might be a more accurate tool in these patients. Numerous guidelines on the management of the cirrhotic patient undergoing invasive procedures have been published but most of them are not evidence based. Current literature, although conflicting, is leaning towards a restrictive approach to prophylactic correction of coagulopathy when performing invasive procedures in cirrhotic patients. The investigators suspect that common practice is more liberal . Considering the well-known adverse effects of blood product administration, the aim of the study is to re-evaluate the clinical management of cirrhotic patients undergoing invasive procedures. Study objectives: asserting whether the use of blood products prior to invasive procedures in cirrhotic coagulopathic patients can be reduced using TEG to evaluate coagulopathy in place of CCTs, evaluating the rate of complications due to blood product use, and checking how well CCT results correlate with TEG results in these patients. This will be a prospective pre/post TEG protocol implementation study which will include two prospective surveys with a 1:1 ratio. Survey 1: prophylactic administration of FFP/PLT prior to minor invasive procedures will be based on CCTs and physicians' clinical judgement. Survey 2: management will be based on a new TEG protocol. The investigators will include cirrhotic patients with coagulopathy who are candidates for an invasive procedure. Subject will be provided with sufficient time to reach a rational, informed decision regarding participation in the study. Data will be collected from the computer based medical record systems, the patient file and directly from the caring physician and will include a thorough medical history and conventional blood tests, including a TEG test. All subjects will be managed according to standard of care. Primary endpoint: amount of blood product (fresh frozen plasma/platelets) units transfused in preparation for the invasive procedures. Secondary endpoints: bleeding complications, transfusion related side effects, 90 day survival and other complications. This will be a prospective (pre/post) study. The calculated sample size needed is 120 subjects, 60 in each group.

The purpose of this study is to evaluate the effect of zinc supplementation in the treatment for dysgeusia, progression disease and quality of life in patients with liver cirrhosis.

Chronic liver injury leads to the accumulation of proteins in the liver that form dense scars. Liver scar formation is typically a slow process that leads to major organ damage and loss of function over the course of many years. During scar formation the extracellular matrix in the liver changes. The type and quantity of extracellular collagen and other proteins change during tissue remodeling. Some of these changes can be detected by analyzing factors present in blood. Because of the lengthy time course, changes in the rate of liver scar formation and regression are very difficult measure; however, accurate measurements are needed in order to conduct trials of interventions aimed at preventing scar formation and/or promotion scar regression. Current methods have sub-optimal specificity and selectivity. The long term objective of the study is to identify serum proteins that can be used to accurately estimate rates of liver fibrosis progression and regression. The project focusses on a novel methodology that uses stable isotope labeling with deuterated water, D2O, to tag newly-synthesized proteins. Mass spectroscopy is used to identify individual proteins and to quantify the ratio of labeled protein to total protein. This ratio provides information about the rate of synthesis of the protein of interest. This method will be applied to specimens from patients with hepatitis C virus (HCV) infection who are about to begin HCV treatment. Treatment is known to reduce liver inflammation and collagen content.

The purpose of this study is to evaluate the safety and efficacy of human umbilical cord mesenchymal stem cell(hUC-MSC) for Hepatic Cirrhosis.

To date, there is no treatment strategies for these patients according to American Association of the Study of Liver Disease (AASLD) practice guidelines and Baveno V consensus. Thus, we aim to compare the safety and efficacy of TIPS and conservative treatment (non-selective beta blockers, endoscopic therapy and/or anticoagulation) in patients with PVT and CPTV.
