Filter by:The standard treatment for decompensated cirrhosis is liver transplantation, however, it has several limitations. Recent animal studies suggest that bone marrow stem cell transplantation can lead to regression of liver fibrosis. The investigators have already completed the phase 1 study of bone marrow mesenchymal stem cell (MSC) transplantation in 4 patients with cirrhosis. The procedure was safe, and feasible, and led to somewhat promising results (Mohamadnejad M, et al. 2006; Submitted for publication). The aim of this study is to find efficacy of this new treatment strategy in the setting of a multicenter, randomized placebo-controlled trial in 50 patients with decompensated cirrhosis.
The purpose of our prospective study was to evaluate the value of Doppler parameters and compare the diagnostic accuracy of Doppler parameters with various biochemical indices in predicting significant hepatic fibrosis (≥ F2) and cirrhosis (F4) in chronic hepatitis C (CHC) patients.
Controlled and randomized study comparing combined treatment (nadolol and endoscopic ligation) versus nadolol associated with isosorbide mononitrate or prazosin according to hemodynamic response, in the prevention of esofagic verices rebleeding.
The purpose of the current study is to look into the pathogenesis of a severe medical condition causing acute episodes on the central nervous system as seen in majority of patients with liver cirrhosis.
The methods for separation of mesenchymal stem cell were established in 2001. These cells can differentiate to osteocytes, hepatocytes, chondrocytes, myocytes and etc,. In this study the investigators try to separate mesenchymal stem cell from end stage liver disease, then these cells will be differentiated to progenitor of hepatocytes, finally , the investigators injected these cells into portal vein under ultrasound guide. The investigators determine the effects of injected cells in reestablishment of liver function.
This study will explore why severe scarring of the liver (cirrhosis) develops so rapidly in hepatitis C-infected patients who have had a liver transplant and possibly in kidney transplant patients as well. The hepatitis C virus (HCV) can cause cirrhosis in about 20 percent of infected persons. Generally, it takes 20 years or more for cirrhosis to develop. After liver transplantation, however, patients may develop cirrhosis in as little as 5 years. Cirrhosis does not develop as rapidly in kidney transplant patients, but it may develop faster than in people who do not undergo transplantation. The study will look at the possible role of immune-suppressing medications given to liver and kidney transplant patients in increasing the severity of hepatitis C infection and in speeding the cirrhotic process. Patients 18 years of age and older with chronic HCV infection who require a liver transplant for end-stage liver disease or a kidney transplant for kidney failure may be eligible for this study. Liver transplant patients are recruited from the Inova Fairfax Liver Transplant Center in Fairfax, Virginia, and from the Georgetown University Medical Center Liver Transplant Institute in Washington, D.C. Kidney transplant patients are recruited from the Transplantation Branch of the National Institute of Diabetes and Digestive and Kidney Diseases. Participants undergo the following procedures: - Regular care: As part of their regular transplant-related treatment, patients have a medical history, physical examinations and blood draws before their transplant and on regularly scheduled visits after the transplant. - Blood draws for research: Special blood tests are done to measure the immune response to HCV. They measure the amount of HCV in the blood, the number of HCV strains present and how they change over time and the HCV antibodies in the blood. - Liver biopsies: This procedure is done at 3 months, 1 year, 3 years and 5 years after the transplant to determine the extent of scarring of the liver and to study the immune responses within the liver, the proportion of liver cells infected with HCV and the presence of scar-producing cells. The biopsy is done during a 1- to 2-day inpatient hospital stay. The patients are given a sedative medication through a vein before the procedure. The skin over the biopsy site is numbed and the biopsy needle is passed rapidly into and out of the liver to collect a small sample of liver tissue for study. - Apheresis: This procedure is done to collect a large number of white blood cells needed to test the immune response to the HCV. On the day before each liver biopsy, blood is drawn through a needle from a vein in one arm and run through a machine that separates and collects the white cells. The red cells and plasma are returned to the patient's body through the same needle or a second needle in the other arm.
Advanced liver disease and low ascitic fluid protein concentration have been identified as risk factors for spontaneous bacterial peritonitis in cirrhosis. Moreover, renal impairment and hyponatremia increase mortality rate of this infection. Aims: To investigate if oral administration of norfloxacin prevents the first episode of SBP, hepatorenal syndrome and improves survival in cirrhotic patients with ascites and low protein concentration in ascitic fluid (<15 g/L) and at least one of the following inclusion criteria: functional renal failure (serum creatinine ≥ 1,2 mg/dl or BUN ≥ 25 mg/dl), hyponatremia (serum sodium ≤ 130 mEq/L) or advanced liver disease (Child ≥ 9 points with serum bilirubin ≥ 3 mg/dl). Methods: Prospective, multicenter, randomized, double-blind placebo controlled trial comparing oral norfloxacin (400 mg/d; n=35) with placebo (n=35).
This 36-month open-label study of adefovir dipivoxil investigates the clinical benefits of the therapy in chronic hepatitis B patients with advanced fibrosis or cirrhosis confirmed with biopsy. Primary endpoint is histological improvement defined as a decrease of Ishak Fibrosis Score by one point or more from baseline at Month 36 of adefovir dipivoxil treatment. Approximately 150 patients will be recruited in study centres in the Asia Pacific area. The patients are offered 36 months of open label adefovir dipivoxil treatment, with assessments every three months, after which there is a 6-month post study treatment follow-up prior to study completion. After the 36 months of study treatment, it is likely that the patient will benefit from continued treatment with adefovir dipivoxil. If this is the case in the investigators clinical judgement, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs.
The purpose of this study is to determine whether a special yogurt can improve performance on certain tests of intelligence and decrease liver inflammation in patients with cirrhosis.
Hepatic encephalopathy (HE) is a frequent complication of chronic liver disease (cirrhosis) and involves a wide spectrum of problems from mild impairment of reaction times in driving and operating machinery through to disturbances in mood, behaviour and conscious levels. Magnetic resonance imaging (MRI) is a method of obtaining pictures of the inside of the body. Patients with liver disease have previously been studied with MRI which has highlighted changes in the brain. This research aims to highlight some of the differences in the way that the brain functions in patients with liver disease. Using our new, more powerful MRI scanner, with more sophisticated techniques we hope that the novel combination of MRI techniques can objectively detect the presence of , and monitor HE. Study hypothesis: Hepatic encephalopathy (HE) is a reversible, metabolic disturbance of the brain, associated with low grade brain swelling and disturbances of the chemical balance within the brain, resulting in functional impairment, the presence of which MR imaging can detect with sufficient sensitivity to monitor the changes that may occur over time in response to treatment.
