Filter by:This study investigated the effectiveness and safety of oltipraz therapy in treating patients with cirrhosis induced by chronic hepatitis type B or C.
The purpose of this study is to evaluate the use of modafinil in the treatment of fatigue in patients with Primary Biliary Cirrhosis. The general aim of the study is to identify a safe and effective therapy for fatigue in patients with primary biliary cirrhosis.
Soluble secreted proteins that are expressed uniquely in specific organs and whose formation of secretion is regulated by disease states are excellent markers for the disease. This is because the disease can be diagnosed by simply measuring the levels of the secreted protein in serum. A soluble form of the asialoglycoprotein receptor could be a promising candidate for such marker in the case of liver fibrosis secondary to steatohepatitis for which the existing markers are not satisfactory. The human asialoglycoprotein receptor (ASGPR) is expressed only in hepatocytes. The H2a alternatively spliced variant of the ASGPR H2 subunit differs from H2b variant only by the presence of an extra pentapeptide. EGHRG, in the exoplasmic domain next to the membrane-spanning segment. H2a is rapidly cleaved to a36 kDa fragment, comprising the entire ectodomain, which is secreted. H2a does not participate in a membrane bound receptor complex with H1 as in the case for H2b and thus it is not a subunit of the receptor but a precursor for a soluble secreted form of the protein (sH2a). Although H2a is a type II transmembrane protein, signal peptidase is probably responsible for the cleavage to the soluble form. The objective in this research proposal is to study the association between the level of sH2a. in the serum and the severity of fibrosis in steatohepatitis in patients undergoing bariatric surgery due to morbid obesity. The existence of sH2a in normal human serum is at very constant levels. On the other hand the membrane ASGPR (expressed exclusively in hepatocytes) is profoundly down - regulated in liver cancer and cirrhosis. The investigators will analyze the levels of sH2a in serum from patients with steatohepatitis in different stages of fibrosis and compare with healthy subjects. A possible early down-regulation of sH2a in fibrosis may prove to be a valuable diagnostic tool.
The value of banding ligation plus beta blocker in the prophylaxis of first episodes of variceal bleeding has not yet been evaluated. This study was conducted to compare the efficacy and safety of banding ligation plus nadolol versus nadolol in the prophylaxis of first bleeding in cirrhotic patients with high-risk esophageal varices.
Background: - Liver cancer is the third most deadly and fifth most common cancer worldwide. Hepatocellular carcinoma (HCC) is the most frequent primary liver cancer, and it has grown more prevalent in the United States. - More information is needed about the causes and effects of liver cancer, and further research into individuals who are at high risk for developing liver cancer is needed for early diagnosis and prevention. Objectives: - To identify genetic factors that may help to explain the aggressiveness of liver cancer. - To determine if HCC biomarkers exist in blood, urine, and tissue samples. Eligibility: - Patients between the ages of 18 and 90 who have been diagnosed with HCC or have a high risk for developing HCC because of fatty liver disease (alcohol-related or non-alcohol-related) or chronic hepatitis B or C. - Participants will reside in Baltimore City and the surrounding areas. Design: - Participants will complete a questionnaire and provide blood and urine samples for testing: - The questionnaire will include questions about individual and family medical history, tobacco use, and exposure to known factors for liver cancer. - Blood and urine samples will be collected from all participants after the questionnaire. - Tumor tissue and healthy tissue will be collected from selected participants if they undergo surgery for their cancer or disease. - No specific treatment will be offered as part of this protocol, but participants have the option to be treated under different protocols.
This is an open, randomized study in patients with different severity stages of hepatic cirrhosis, in which rater pairs will be used for the assessment of the intra- and inter-rater reproducibility of NRL972 pharmacokinetics and CTP sum score. Rating will be performed by 32 to 40 pairs of raters. The raters will perform the required assessments in the capacity of sub-investigators of the phase I (co-ordinating) unit. Up to 240 patients with clinically established hepatic cirrhosis without confounding end-stage co-morbidity (stable disease) will be studied. Within 30 days of confirmation of eligibility, Visit 1 will take place to determine the investigational parameters (NRL972 pharmacokinetics, clinical laboratory tests, and determination of CTP sum score). At approximate intervals of one week, Visits 2, 3 and 4 will occur, and the investigational parameters will again be assessed.
This study will assess the repeatability of Magnetic Resonance Elastography (MRE) in both healthy volunteers and Hepatitis C Virus (HCV)-infected patients with fibrosis and lay the groundwork for the validation of MRE as an alternative to liver biopsy.
Estimation of functional liver reserve in patients with hepatocellular carcinoma (HCC) in cirrhosis is of paramount importance to properly select candidates for surgical resection. Together with the value of bilirubin, the presence/absence of ascites and esophageal varices, and the rate of residual liver volume, which are our current parameters to measure functional liver reserve, the investigators sought to investigate the value of preoperative cholinesterases (CHE) in predict postoperative adverse outcome after hepatic resection for HCC.
A study in healthy volunteers to determine whether different drugs metabolised by the liver have any effects on how NRL972 is processed within the body.
The study was conducted to describe and compare the plasma pharmacokinetics of NRL972 administered after a standard meal and while fasted in patients with hepatic cirrhosis (Child-Turcotte-Pugh [CTP] class A-C), NASH, young and elderly healthy males, and young and elderly healthy females, to assess the effects of liver dysfunction, gender, age and prandial intestinal hyperaemia on the clearance of NRL972. In addition, the study was to provide information on the safety and tolerability of repeated intravenous doses of NRL972 in these populations.
