11 Clinical Trials for Various Conditions
Sirolimus can be safely switched as early as 90 days after liver transplantation with excellent tolerability and amelioration of the calcineurin inhibitor toxicity that initiated the switch.
When someone has hepatitis C or some other condition that causes liver injury, he or she can develop a condition called liver fibrosis that over time, can cause the liver to stop working normally. Currently, the best way to determine the degree of fibrosis is to do a liver biopsy. The investigators hope to show that measuring the degree of liver fibrosis using an MRI with gadoxetate disodium is as good as or better than obtaining this information by performing a liver biopsy. Gadoxetate disodium is a contrast solution given through the veins that is considered safe, is approved for use by the Food and Drug Administration, and is already routinely given to patients with various forms of liver disease, including fibrosis.
The primary objective of this study is to assess the clinical performance of LIVERFAStTM In Vitro Diagnostic (IVD) Tests (Fibrosis score, Activity score and Steatosis score) in NAFLD suspected patients for staging of fibrosis and for grading of inflammatory activity and steatosis, taking as reference the liver biopsy with histological classification of the elementary lesions determined according to SAF scores (Bedossa P., Hepatology 2012). The secondary objective is to assess the performance of LIVERFAStTM for the histological definition of NAFLD, including NAFL and NASH and severe NASH
Background: - Hepatitis C infection (HCV) is a leading cause of liver disease. Normal bacteria from the intestines may spread to the liver and blood during liver disease. This is called bacterial translocation (BT). Researchers think BT may cause liver disease to worsen. Objectives: - To study the mechanisms involved in BT in early and advanced liver disease. To find out whether BT causes liver disease to worsen. Eligibility: - People over age 18 with HCV and clinically stable liver disease. Design: * Participants will be screened with medical history and physical exam. They will have blood tests and imaging studies. * Participants will have 2 outpatient visits and a 3-day stay at the clinic. * At visit 1, participants will have urine and blood tests. They will have a magnetic resonance imaging (MRI) scan. A solution will be injected into a vein. The MRI scanner is a metal cylinder surrounded by a magnetic field. The participant will lie on a table that slides in and out of the cylinder. * At visit 2, a substance will be injected into a vein and swallowed. Participants will then have blood drawn 5 times over 90 minutes. * During the inpatient stay, serial blood tests will be drawn. * Participants will give 2 stool samples and have another MRI. * A needle will be inserted through the chest wall into a vein inside the liver, guided by ultrasound. The blood pressure inside this vein will be measured and blood will be drawn from it. About 1 inch of liver tissue will be removed. * A study investigator will call participants to discuss all test results.
The primary objective of this study is to evaluate whether SIM (formerly referred to as GS-6624) is effective at preventing the histologic progression of liver fibrosis and the clinical progression to cirrhosis in participants with NASH. It will consist of 2 phases: * Randomized Double-Blind Phase * Open-Label Phase (optional)
The purpose of this study is to evaluate whether simtuzumab (GS-6624) is effective at preventing the progression of liver fibrosis in adults with primary sclerosing cholangitis (PSC).
This study will provide a basis for research on the impact of liver injury caused by antiretroviral therapy in HIV-infected patients. Elevated liver enzymes called AST and ALT are common in HIV-infected patients taking antiretroviral medications and can indicate liver damage. Although there are a number of possible causes for these elevations, such as infections with a hepatitis virus, antiretroviral medications alone can lead to the elevations. The study will focus particularly on evidence of liver fibrosis, which is a sign of progressive liver damage. HIV-infected patients 18 and older who 1) have been taking combination antiretroviral therapy for at least 12 months and have been on a stable regimen for at least 3 months, and 2) have had elevated AST or ALT levels for at least 6 months may be eligible for this study. Patients who have had liver biopsies performed in the past may be eligible for participation. Participants undergo the following tests and procedures over a 12-month period: * Oral glucose tolerance test: The patient drinks a glucose (sugar) drink. Blood samples are then drawn over 2 hours through an intravenous (IV) line in the patient's arm. This test measures how high the patient's blood sugar and insulin levels rise after drinking a standard glucose load. * Transient elastography: This ultrasound test uses vibration (sound waves) to measure liver stiffness (fibrosis). Vibrations move faster through a fibrotic liver. * Triple-phase CT scan and single slice CT scan of L4-5: Patients fast for 4 hours before the CT scan. A contrast material is injected through a catheter placed in an arm vein to improve the visibility of the liver in the specialized X-ray images obtained in the CT scanner. * Liver biopsy: This test removes a small sample of liver tissue for microscopic examination, particularly for evidence of fibrosis. The skin over the biopsy site is numbed and a needle is passed through the skin and rapidly in and out of the liver. Patients may be given a sedative for the procedure. * Follow-up visits. Patients return for follow-up visits 1 to 4 weeks after the liver biopsy and three more times over the course of the study for a medical history, physical examination and blood tests. Patients may participate in an additional 4-year follow-up, during which they have visits every 3-12 months and are offered the opportunity to repeat the biopsy no sooner than 1 year after the first biopsy.
The primary objective of this study is to evaluate the safety and efficacy of SIM (formerly referred to as GS-6624) in adults with compensated cirrhosis due to Non-Alcoholic Steatohepatitis (NASH). It will consist of 2 phases: * Randomized Double-Blind Phase * Open-Label Phase (optional)
The study is being done to collect information on the effectiveness of endosonographic elastography (a technique which uses sound waves) to measure the stiffness of the liver and spleen. Investigators are trying to determine if shear wave elastography is a good way to measure fibrosis instead of biopsy.
Chronic liver disease is a major problem in the general population and there is an unmet need to diagnose(and screen) for liver disease with using noninvasive, cost-effective and sensitive techniques.The investigators hypothesize that variation using ultrasound elastography for the estimation of stage of liver fibrosis and steatosis in patients with diffuse liver disease exists due to different methods of measurements, and/or different systems. The proposed investigation is a cross-sectional study using ultrasound elastography and fat quantification modalities. The investigators are planning to enroll 30 subjects 18 years old and older in whom diffuse liver disease is suspected, and who have undergone non-focal liver biopsy in the past 6 months or are scheduled to undergo biopsy within 3 months of enrollment, as part of their routine clinical care. The investigators will use 4 different ultrasound devices with their shear wave elastography and speed of sound functions. Specific aims; * Compare shear wave elastography(SWE) measurements from different ultrasound systems; using histopathology as reference standards. * Assess intra-operator and inter-operator reliability by measuring variability in elastography values by two operators on a single system. * Determine the effect of deviations from guidelines(less number of measurements and measurements during active breath)
This is research study is assessing the effects of 6-g daily use of freeze-dried instant coffee on liver fat and fibrosis and the gut microbiome and metabolome in patients who have completed routine treatment (including surgery, chemotherapy and radiotherapy) for stage I-III colorectal cancer.
