Filter by:Background: - Noncirrhotic Portal Hypertension (NCPH) is caused by liver diseases that increase pressure in the blood vessels of the liver. It seems to start slowly and not have many warning signs. Many people may not even know that they have a liver disease. There are no specific treatments for NCPH. Objectives: - To learn more about how NCPH develops over time. Eligibility: - People age 12 and older who have NCPH or are at risk for getting it. In the past year, they cannot have had other types of liver disease that typically result in cirrhosis, liver cancer, or active substance abuse. Design: - Participants will have 2 screening visits. - Visit 1: to see if they have or may develop NCPH. - Medical history - Physical exam - Urine and stool studies - Abdominal ultrasound - Fibroscan. Sound waves measure liver stiffness. <TAB>- Visit 2: - Blood tests - Abdominal MRI - Echocardiogram - Questionnaire - Liver blood vessel pressure (hepatic venous portal gradient (HVPG)) measurement. This is done with a small tube inserted in a neck vein. - They may have a liver biopsy. - All participants will visit the clinic every 6 months for a history, physical exam, and blood tests. They will also repeat some of the screening tests yearly. - Participants with NCPH will also have: - Upper endoscopy test. A tube inserted in the mouth goes through the esophagus and stomach. - At least every 2 years: Esophagogastroduodenoscopy. - At least every 4 years: testing including HVPG measurements and liver biopsy. - Participants without NCPH will also have: - Liver biopsy and HVPG measurements to see if they have NCPH. - Every 2 years: abdominal MRI and stool studies. - The study will last indefinitely.
In 2005, The University of Alabama at Birmingham established a NIDDK-funded, interdisciplinary center of excellence in PKD-related research, with specific emphasis on recessive PKD. In the previous Core Center award period, we developed a Core Resource to capture clinical and mutational data for ARPKD patients ("Core A: ARPKD Clinical and Genetic Resource", NCT00575705). However, studies in the last several years have demonstrated that ARPKD and other single gene disorders characterized by renal cystic disease and extra-renal phenotypes share numerous pathogenic features. In the current competitively- renewed Center, we have expanded this Core resource to include other hepato/renal fibrocystic diseases. Goals for the Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource are: 1. - Clinical Database: • Expand our comprehensive Clinical Database to include information from all patients who meet the inclusion criteria for hepato/renal fibrocystic diseases. 2. - Mutational Database: - Test children with ARPKD and other hepato/renal fibrocystic disease to identify genetic mutations, establish a DNA bank for patients with hepato/renal fibrocystic diseases and develop a Mutational Database. This Database will be capable of linking clinical and mutational information via a unique identifier in a searchable format to facilitate genetic research (e.g. genotype-phenotype correlations, new disease gene studies, and modifier gene studies), translational studies, and clinical trials. 3- Tissue Resource: - Much of the research that is performed on diseases of the kidney, including recessive genetic diseases, requires human tissue from both affected as well as non-affected (controls) individuals. In this Core Resource, we are establishing an independent tissue resource which would supply investigators throughout North America with samples of hepato/renal fibrocystic disease affected tissues for studies of these disorders. 4- Educational Resource: - Expand our multi-media, web-based resource to provide a reliable up-to-date, and comprehensive informational resource for ARPKD and Hepato/Renal Diseases families, their physicians, and genetic counselors.
