The Foundation for the Study of Viral Hepatitis (FEHV) is a non-profit organization leader in the field of hepatology at international level, with the best specialists in liver diseases and molecular biology. In our clinic located in Madrid, we treat all kinds of liver diseases (autoimmune hepatitis, cholangitis, fatty liver, viral hepatitis, etc.) Led by Vicente Carreño, MD, PhD, we have medical specialists in internal medicine, hepatology, nephrology and digestive medicine, and specialists in the latest advances in radiology and ultrasound. We actively collaborate with the Foundation for Biomedical Research, for researching in new advanced diagnostic techniques for the study of hepatic diseases. In Clinic FEHV we offer the best quality standards and medical service that have made our team be internationally acclaimed. The Foundation for the Study of Viral Hepatitis (FEHV) is a nonprofit foundation committed to the study of liver diseases. It was in 1990 when Vicente Carreño, MD, PhD created the Foundation to develop new and effective treatments for liver diseases. His passion for research and professional ambition led him to create a foundation that has given rise to internationally recognized medical breakthroughs. The idea for the foundation came after visiting the Royal Free Hospital of London (1979-1982), where Doctor Carreño specialized in hepatology. At this hospital, her tutor, Professor Sheila Sherlock, one of the best doctors specialized in the study of the liver, for which she was nominated six times for the Nobel Prize in Medicine, Dr. Sherlock, president and co-founder of the International Association for the Study of Liver from 1958 to 1962, pushed Dr. Carreño to develop his career in Hepatology. On his return to Spain, Vicente Carreño completed his doctoral thesis, so that in 1985 he received his doctorate with Cum Laude and Special Prize of the Faculty of Medicine, Autonomical University of Madrid. He served as Deputy Medical Gastroenterology Service of the Fundación Jiménez Díaz of Madrid from 1980-1995 and in 1995 created the Department of Hepatology, Fundación Jiménez Díaz, he was nominated Head of the department and at the same time for the position of deputy director of research, and remain so at this institution until 2000. From that date, he moved with his team to the headquarters of the Foundation for the Study of Viral Hepatitis that was created in 1990. Since then, FEHV evolved having now medical consultations, the most advanced medical technical equipment, a large team of doctors and biologists and two laboratories for the diagnosis and medical research. The objectives of the FEHV are to promote the study of liver and kidney diseases and spread the latest treatment techniques. This is the reason why the FEHV funds research in the field of hepatology and nephrology through laboratory equipment and various other reagents. It contributes to the economic support of those fellows, or employee or contracted FEHV personnel for research, who participates in the implementation of these projects. It also awards grants to researchers to expand their studies at foreign institutions. Among the most important achievements of the FEHV is the remarkable discovery in 2004 of a new form of hepatitis, termed “occult infection by the hepatitis C virus”, published in the Journal of Infectious Diseases U.S.A. These studies had a major impact, they appeared more than 100 times in the national and international print media, as well as on television and radio shows. Thanks to these discoveries and to the high analytical technology of our Foundation, we diagnose patients with a liver disease of unknown origin. This allows us to provide with appropriate treatments to patients who previously did not receive any. Located in Madrid, Spain, the Clinic Foundation for the Study of Viral Hepatitis, has over 5000 sqft of facilities to provide the best service. We have three medical offices, two research labs, ultrasound and radiology equipment, among other resources.
