Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
