Filter by:There is increasing evidence that hepatic lipid content (IntraHepatic Lipid, IHL) markedly increases the risk of metabolic complications, including insulin resistance and cardiovascular events. The investigators hypothesize that the liver is passively taking up free fatty acids (FFA) when the availability is high, thereby leading to an increased storage. To test this hypothesis, the investigators want to manipulate FFA levels, by means of a fasted exercise and recovery protocol, and monitor IHL content and hepatic Adenosine triphosphate (ATP) and inorganic phosphate (Pi) concentrations.
This study will assess - whether coffee consumption protects against fructose-induced hepatic steatosis in healthy humans - whether the protective effect of coffee is dependent on it's antioxidant composition
There has been a recent increase in incidence of obesity and its associated morbidities, including T2 DM, hypertension and hepatic steatosis. Hepatic steatosis is a precursor to non-alcoholic steatohepatitis, cirrhosis and end-stage liver disease. The 1st reported case of pediatric hepatic steatosis was in 1980 and it is now affects 30-77% of overweight children. In addition to its association with obesity, hepatic steatosis has been associated with the metabolic syndrome, insulin resistance, and post-prandial hyperglycemia. Current treatment of hepatic steatosis includes weight loss with a hypocaloric low fat diet. Given the association with insulin resistance and post-prandial hyperglycemia, adult patients with hepatic steatosis that does not respond to weight loss are placed on insulin sensitizing drugs. We hypothesize that weight loss with a diet designed to decrease insulin resistance and post-prandial hyperglycemia, a low glycemic load diet, will provide a safe and effective way to decrease hepatic fat content in the pediatric population. This hypothesis will be tested with a randomized control trial comparing the effect of a low fat diet with a low glycemic load diet.
Lipodystrophies represent a therapeutic challenge with regards to the management of the diabetes, insulin resistance, hypertriglyceridemia and fatty liver which frequently present in conjunction with significant adipose tissue loss. The purpose of the study and it's four subprojects is to examine the safety and efficacy of various novel interventions designed to improve or resolve the fatty liver, hypertriglyceridemia, and insulin resistance or diabetes that is seen in these patients.
To evaluate the efficacy and safety of cholic acid therapy in treating lipodystrophy patients with hepatic steatosis. This is a randomized, double-blind, placebo-controlled cross-over study.
Hepatitis C virus infection (HCV) is a major health concern in Canada and worldwide. Chronic HCV can cause progressive liver damage leading to inflammation, scarring and, in some cases, cirrhosis or liver cancer. It has been shown that fat accumulation in the liver can accelerate the disease progression and is therefore a risk factor in HCV patients. However, the exact mechanism(s) by which fat accumulation in the liver is involved in disease progression are not clear yet. It is possible that the presence of fat provides a liver susceptible to a second injurious process which leads to scarring. Candidates for this second "hit" may include insulin resistance, leading to accumulation of fat within the liver cells and secondly oxidation of these lipids. In turn, lipid peroxidation can lead to production of reactive oxygen species (unstable molecules that can damage cells) and cytokines (signal molecules that promote inflammation) resulting in more oxidative stress and liver damage. Aim of the study is to find out, whether patients with HCV and fatty liver have increased oxidative stress and inflammation than patients with HCV without fatty liver, and whether this is associated with a different nutritional status.
This study will determine whether pioglitazone (Actos, a drug approved to treat diabetes, can benefit HIV-infected people with fatty liver. Fatty changes of the liver (also known as steatosis) have been linked to diabetes and long-term liver damage in some patients. Pioglitazone has been shown to improve fatty liver in people without HIV; this study will see if it is beneficial for people with HIV as well. HIV-infected patients 18 years of age and older with increased fat in the liver may be eligible for this study. Screening includes a CT scan and liver biopsy (withdrawal of a small sample of liver tissue through a needle). Participants are randomly assigned to take either 45 mg of pioglitazone or placebo (sugar pill) by mouth once a day for 48 weeks. At the end of 48 weeks, all participants stop taking their medication and are followed for an additional 48 weeks to see what, if any benefits, of pioglitazone persist after treatment is stopped. In addition to taking the study medication, participants undergo the following procedures: - Visits to the NIH Clinical Center over a period of approximately 2 years at day 0 and weeks 2, 8, 16, 24, 32, 40, 48, 52, 72, and 96. Most visits take about 1 hour and include blood drawing for various laboratory tests. - Insulin clamp test at day 0 and weeks 24 and 48 to see how the body processes glucose. This test takes 4 to 6 hours and may include an overnight stay at the Clinical Center. A catheter (plastic tube) is placed in a vein in the arm to infuse insulin and another is placed in a vein on the back of the hand to draw blood samples. Blood sugar is checked frequently and glucose is given to keep blood sugar at normal values. - Nutrition evaluations at day 0 and weeks 24 and 48. Subjects write down all the food they eat and drink for 4 days before the visit. They meet with a nutritionist to review the food record and to complete simple measurements of body fat and shape. - CT scan of liver and abdomen at weeks 24, 48, 72 and 96. - Liver biopsy at week 48.
