PATHOPHYSIOLOGY, PREVENTION AND TREATMENT OF END-STAGE LIVER DISEASE (PI B. van Hoek)
Most chronic liver diseases lead towards cirrhosis and its complications, and a.o. acute and chronic liver failure can be indications for liver transplantation. The aim of our research is prevention of these end-stages by a better understanding and treatment of the underlying liver diseases, and the complications of advanced liver disease. While we undertake and participate in various, mainly translational and clinical, investigations in different acute and chronic liver diseases, the focus currently is on auto-immune and metabolic liver disease, and shifting away from viral liver disease. Biobanking and clinical databases are part of the basic infrastructure for many of these studies. In our clinical trial bureau several study nurses lead various -mostly phase 2 and 3- clinical studies in liver diseases. In vitro studies to understand pathophysiology are done..
LUMC is one of the founders of the Dutch Autoimmune Hepatitis Group, which started in 2005 and is a national cooperation of all academic and larger other hospitals. It is part of the worldwide International Autoimmune Hepatitis Group, and joint clinical investigations on presentation, treatment and outcome are being performed. Especially B-cell auto-immunity, genetics, inflammation and fibrogenesis is investigated in cooperation with the immunohematology department of the LUMC. We participate in the national Cholestasis Working Group for joint investigations on cholestatic liver disease and overlap syndromes (e.g. genotype-phenotype studies in PSC and clinical studies with new drugs and on outcome in PSC and PBC). For viral hepatitis LUMC is part of HepNed, a cooperation of Dutch hepatitis treatment centers, for joint clinical investigation, e.g. with the new direct antivirals and as part of the CELINE initiative aiming at elimination of hepatitis C from our country. LUMC is a reference center for alpha-1-antitrypsin deficiency (A1ATD); the focus has been on lung disease, but now is also on liver disease from A1ATD as part of a cooperation from the European Association for the Study of the Liver (EASL). Investigations in acute and acute-on-chronic liver failure are ongoing, and recently we joined a European group aiming at bringing bioartificial liver support to the clinic.
Hepatitis and cholestasis lead to liver fibrosis, which leads to cirrhosis and liver failure. Fibrosis is a bad prognosticator in many liver disease. An important aim for current treatments is prevention of development of liver fibrosis and cirrhosis. This is investigated clinically, with non-invasive monitoring liver diseases and its treatment with e.g. Fibroscan and blood tests, but also in vitro and in vivo in our lab, where novel models have been developed. The influence of novel drugs and mesenchymal stem cells on several pathways and matrix proteins is investigated.
After having perfomed the first liver transplantation (LT) in our country in 1966 (one of the first worldwide), since 1992 the LUMC is one of the three liver transplant programs in the Netherlands. While clinical results are above the European average and quite reasonable compared to the early days (90% patient survival at 1 year and 85% at 5 years), improvements are still being made on a continuous basis. Our studies focus on pathophysiology, treatment and prevention of LT complications. This includes studies on immunosuppression, prevention of its side-effects like renal insufficiency, infections, biliary strictures, bone disease, and nutrition before and after LT. Within the RADIcAL2 study the cost-effectiveness and accuracy of noninvasive diagnostics with MRI of a.o. biliary disorders after liver transplantation is investigated, within a European consortium. LUMC participates in (inter)national machine liver preservation trials in order to improve outcomes. Side-studies of these trials allow better insight into ischemia-reperfusion injury. Improving quality of life after LT is an important aim. Extending LT indications for malignancy combined with locoregional and systemic treatments in order to maintain acceptable outcomes currently also is a focus. Bridging therapies to transplantation are investigated.

Biosketch Bart van Hoek
Bart van Hoek, M.D., Ph.D. is gastroenterologist –hepatologist since 1993 at the Leiden University Medical Center, Leiden, The Netherlands. After graduating as medical doctor (Groningen, 1982 and USA VQE, London 1984), he completed his specialization in Internal Medicine (Groningen, 1988), and obtained a PhD with a thesis on auto-immune hepatitis (Groningen, 1989). He worked at Mayo Clinic, Rochester MN, U.S.A. for two years during a research fellowship followed by a clinical fellowship in advanced clinical hepatology (1989-1991). In 1991-1992 he finished his specialization in Gastroenterology and Hepatology, at the same time working as a hepatologist in Maastricht UMC, Netherlands. Since January 1993 he was cofounder of the Hepatology and Liver transplantation unit at LUMC Leiden, where he is Medical Director of this program. Since 2009 he is also Professor of Hepatology at Leiden University. His clinical focus is on auto-immune hepatitis, cholestatic and viral liver disease, end-stage liver disease, liver failure and liver transplantation.
He is actively involved in scientific research in the field of complications and treatment of auto-immune and viral liver disease, fibrosis, alfa-1-antitrypsin deficiency (A1ATD), liver failure and complications, and liver transplantation. His main focus in AIH is on immunology, fibrogenesis, genetics and co-factors, non-invasive diagnosis/monitoring and outcome. In liver transplantation reduction of side-effects of immunosuppression, complications of ischemia-reperfusion injury, waitlist management, transplantation for malignancy and bridging to transplant are important fields of interest.
Next to clinical work and research he is involved in training specialists in gastroenterology and hepatology, in internal medicine, and the training for physician assistants and nurse specialists, and he is educator at the medical school of Leiden University.
Prof. van Hoek currently is as board member of the Eurotransplant Liver and Intestinal Advisory Commission, is chair of the cooperation between the three Dutch liver transplant centers, and is member of the management team of the LUMC Transplant Unit. He is member of several medical societies, a.o.: International Liver Transplant Society (ILTS), European Society for Organ Transplantation (ESOT), European Liver Intestinal Transplant Association (ELITA), European Association for the Study of the Liver (EASL), American Association for the Study of Liver Disease (AASLD), and the Dutch Societies for Gastroenterology and Hepatology (past treasurer).
