Future in treatment of chronic liver disease. Leading expert in liver disease and vascular biology. How advances in understanding of vascular inflammation help improve treatment of chronic liver disease. How chronic liver inflammation changes energy balance in liver. Where therapy of liver disease will focus in the future? Future in treatment of chronic liver disease. Dr. Anton Titov, MD. Video interview with leading expert in liver diseases, liver transplantation and vascular biology. Dr. Simon Robson, MD. Treatment methods for viral hepatitis and non-viral hepatitis. Therapy for fatty liver disease and metabolic syndrome. Epidemic of overnutrition and mutated grains, including wheat. Medical second opinion helps to make sure chronic liver disease diagnosis is correct and complete. We are looking at a bright future in treatment of chronic liver disease. Medical second opinion also helps to choose the best treatment for liver disease, hepatitis, steatohepatitis. Dr. Anton Titov, MD. We discussed toxic diseases that affect the liver: aflatoxins, environmental pollutants and NSAIDs. Dr. Simon Robson studies purinergic signaling. He works on extracellular enzyme CD39. CD39 can be important mediator of effect of statins on vascular wall. In 2016 there will be a Keystone symposium in Vancouver on Purinergic Signaling. Dr. Simon Robson, MD. Future in treatment of chronic liver disease is focused on diet and lifestyle changes. Future in treatment of metabolic syndrome and fatty liver disease. Dr. Anton Titov, MD. We spoke about toxic diseases that affect the liver. We discussed viral hepatitis and non-viral hepatitis, fatty liver disease. Dr. Anton Titov, MD. Where is hepatology going? Hepatology is study of liver diseases. Where do you see the most progress in treatment of liver disease in the next 10 years? Dr. Simon Robson, MD. Gastroenterologist, Harvard Medical School. We need to address this epidemic of overnutrition. We need to tackle metabolic syndrome and fatty liver disease. We may find that it is not just nutrient excess that is causing these problems. We may find that altered microbiome, other aspects of hygiene hypothesis, and some environmental factors predispose us to metabolic syndrome and fatty liver disease. Right now we don't have any major therapeutic interventions. Dr. Simon Robson, MD. These are effective medicines to treat metabolic syndrome and fatty liver disease. There are a couple of medicines in development. They seem to delay scarring of the liver. But these new medicines to treat fatty liver disease and metabolic syndrome provoke changes in cholesterol levels. These changes in cholesterol metabolism could be bad for the body. that is one of the major areas of liver disease research. My laboratory studies purinergic signalling. Our research shows that cells use ATP is an energy currency. Sometimes cells release the ATP under diseases of stress. Cells are under stress when blood clotting or inflammation happens. ATP is released. ATP works as hormone and binds to receptors. This process triggers inflammation and thrombosis (clotting). My laboratory works on enzymes that remove the ATP from the outside of cells. These enzymes make adenosine, this has the opposite effect to the ATP. Dr. Simon Robson, MD. The food and nutrients, as we discussed, can cause fatty liver disease. The final common pathway of the disease process is a generation of energy. the currency of energy in the cell is ATP. Metabolic syndrome happens when there is metabolic stress on the body. It is possible that excess ATP causes metabolic stress and metabolic syndrome. purinergic signalling is a major factor in metabolic syndrome. We have models of fatty liver disease. We showed that purinergic signalling is involved in creating fatty liver injury. We showed that high levels of the ATP can provoke diabetes with insulin resistance. We have discovered in great detail how this happens. Fatty liver injury and fatty liver disease. The ATP leaks from the cells during inflammation. Inflammation is possibly a consequence of ATP release. Dr. Simon Robson, MD. I propose that ability of the body to metabolize ATP more efficiently will preclude inflammation. It is curious that medicines this improve lipid levels (statins) also decrease inflammation. 50% of the benefit of statin medications comes from their effect on the vascular wall. Statins have effect on the wall of vessels to control inflammation. Statins seem to stabilize the ectoenzyme, extracellular enzyme, called CD39. Dr. Simon Robson, MD. We are working on this CD39 enzyme in my laboratory. Statins prevent loss of CD39 from vascular lining. Statins also prevent CD39 from being damaged. This action of statins allows CD39 enzyme to continue clearing ATP from the surface of the endothelium. Endothelium is inner lining of blood vessels. Many of effects of statins could be related to this action on purinergic signalling. Also effects of other medications could modify activity of CD39 enzyme. Our research also shows that phospholipids are important for CD39 enzyme activity. We are looking at ways of targeting CD39 enzyme to maintain activity at the vascular interface. This area of medical research can be very fruitful. We will organize a Keystone symposium in 2016 in Vancouver. Dr. Anton Titov, MD. Keystone Symposium is a prestigious gathering of leading scientists to discuss a particular theme of research. Our Keystone symposium in Vancouver will address purinergic signalling in inflammation, liver diseases (fatty liver disease), gastrointestinal diseases and also in cancer. Dr. Simon Robson, MD. I will be very happy to provide you information about our Keystone symposium on purinergic signalling. Thank you very much for your interest! Dr. Anton Titov, MD. Professor Robson, thank you very much for this very interesting conversation. We discussed a lot of aspects of the liver disease. Dr. Anton Titov, MD. We talked about prevention of liver disease and treatment of liver disease, fatty liver disease. I'm sure that many viewers will also appreciate your expertise and sharing your wisdom with us. Thank you very much! Dr. Simon Robson, MD. It was an absolute pleasure. Dr. Anton Titov, MD. Thank you very much for coming over! Future in treatment of chronic liver disease.
