Clinical Trial: Evaluation of Patients With Liver Disease
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational
Official Title: Evaluation of Patients With Liver Disease
Brief Summary:
The proposed study aims to evaluate, investigate, and follow-up patients suffering from acute and chronic liver disease. The study will focus on understanding diseases affecting the liver.
Patients participating in the study will first undergo a routine check-up as an outpatient. They will be asked to provide blood and urine samples for laboratory testing and will undergo an ultrasound of the liver. Ultrasound examinations use sound waves to determine the size and texture of the liver. After the initial visit subjects will be requested to follow-up once a year at the outpatient department for a similar check-up.
Additional tests may be requested throughout the study to provide information for other research studies and individual consent will be requested. These tests may include liver biopsies, skin biopsies, and / or specialized blood, plasma, and lymphocyte examinations.
Subjects that qualify for medications presently being studied may be offered the opportunity to benefit from experimental therapy.
Detailed Summary: This is a general clinical research protocol to allow for evaluation, investigation and long-term follow up of patients who have an acute or chronic liver disease. The protocol is designed to study the natural history and pathogenesis of various liver diseases such as acute and chronic hepatitis B, C, D and E, primary biliary cirrhosis, primary sclerosing cholangitis, Wilson's disease, hemochromatosis, nonalcoholic steatohepatitis (NASH), noncirrhotic portal hypertension, hepatocellular carcinoma, and cryptogenic or poorly defined forms of chronic liver disease. Patients will initially be seen in the outpatient department and undergo a medical history and physical examination. They will have a series of blood and urine tests and abdominal ultrasound. Patients will then be followed in the outpatient department with visits every 1 to 12 months at which times they will undergo an interim medical history and brief examination and have blood studies taken. Liver biopsies will be done as a part of this protocol only if clinically indicated, and a separate consent form is provided. In addition, patients may be asked to undergo skin biopsy, plasmapheresis, lymphapheresis, genetic analysis, and Fibroscan procedures for research purposes only (immunologic, virologic, genetic, and other studies) and separate consent forms are provided. Patients qualifying for therapeutic or other trials of antiviral or immunomodulatory agents for their liver disease will be invited to enter such studies.
