Summary
Brief summary
Hepatic steatosis (fatty liver) is now the most common liver disease in western countries and NASH (fatty liver with inflammation) related cirrhosis and its complications is set to become one of the most important causes of liver related morbidity and mortality. It is clear that treatment and control of predisposing factors such as obesity and diabetes can lead to improvement in liver fibrosis (scarring) in patients with NASH however this is not possible in many patients. At present there are no established drug treatments which have been able to prevent liver fibrosis due to NASH.
The renin-angiotensin sysytem (RAS) plays a central role in controlling blood pressure and sodium balance. Angiotensin II (the effector molecule) is a regarded as a key player in the general response to tissue injury in a number of organ systems, including the liver. A number of studies (experimental and human) have shown an improvement in fibrosis when the effects of AII are blocked.
This study will assess the ability of telmisartan therapy to decrease the formation of fat and scar tissue in the liver in patients with fatty liver disease. It will also study the effects of telmisartan on other factors commonly found in patients with fatty liver including obesity and insulin resistance. Telmisartan will be given for a period of 12 months. A liver biopsy will be performed prior to enrolment and then at 12 months. At each visit (3 monthly after the first month) a blood sample and medical consultation will be performed.
