Filter by:The purpose of this study is to determine if orlistat (Xenical) therapy in overweight patients with NASH leads to enhanced weight loss over time, with subsequent improvement in the underlying necroinflammatory and fibrotic changes that are typical of NASH.
The purpose of this study is to evaluate the effect of a one-year nutritional intervention with either betaine or vitamin E supplementation, or a weight reducing diet and exercise program on liver steatosis and steatohepatitis.
This study aims to evaluate the impact of nasal continuous positive airway pressure (nCPAP) treatment on liver enzymes in patients with sleep apnea syndrome and nonalcoholic steatohepatitis. Using a cross over design, the evolution of liver enzymes will be evaluated in 40 patients during a consecutive period of 6 weeks, with and without nCPAP treatment.
The purpose of this study is to examine the effect of S-adenosylmethionine therapy in those patients with non-alcoholic liver disease in the form of steatohepatitis (NASH). This will be accomplished by development of a database of these patients, all of whom will have biopsy documented NASH. A placebo controlled trial will then examine the effect of S-adenosylmethionine over time on clinical outcome in these patients. It is expected that this agent will slow or halt the progression of this disease.
Non-alcoholic fatty liver disease (NAFLD) is an accumulation of fat and fibrous tissue in the liver. It is the most common cause of chronic liver disease in the United States. The exact cause of NAFLD is unknown, but it is more common among people with conditions such as adult-onset diabetes. NAFLD can strike people of all ages but most often affects adults between the ages of 40 and 60. Research indicates that overgrowth of gut bacteria can start a chain of biological processes that stress the liver, causing liver inflammation. Probiotics, living bacteria taken orally, may decrease the stress on the liver by reducing this bacterial overgrowth and/or strengthening the gut walls. Because probiotics are generally safe, inexpensive, and easy to tolerate they are an attractive treatment option for NAFLD.
The purpose of this study is to determine whether probiotics, bacteria that may improve liver health, can effectively treat a chronic condition in diabetics that increases fat in the liver.
The purpose of this study is to determine if therapeutic modification of insulin resistance or oxidative stress leads to improvement in serum or histologic indicators of liver injury or quality of life.
The purpose of this study is to determine if therapy with pioglitazone or vitamin E will lead to an improvement in liver histology in non-diabetic adult patients with non-alcoholic steatohepatitis (NASH).
Nonalcoholic Steatohepatitis (NASH) is associated with progressive liver disease, fibrosis, and cirrhosis. Although the cause of NASH is unknown, it is often associated with obesity, type 2 diabetes, and insulin resistance. At present, there are no approved treatments for NASH patients, but an experimental approach has focused on improving their insulin sensitivity. Metformin is one of the most commonly used medications for the treatment of diabetes. The purpose of this study is to determine whether the medical problems of NASH patients, specifically liver damage, improves when their insulin sensitivity is enhanced with metformin. The study will last 3 to 5 years and will enroll up to 30 patients. Participants will undergo a complete medical examination, a series of lab tests, and a liver biopsy. They will then start taking a single 500-mg tablet of metformin once a day for 2 weeks, then the same dosage twice a day for 2 more weeks, if they tolerate the first dosage. The dosage will increase to 1,000 mg twice a day for the remaining 44 weeks of the study. After 1 year, participants will undergo a repeat medical examination and liver biopsy.
Nonalcoholic steatohepatitis (NASH) is a common liver disease that resembles alcoholic hepatitis but occurs in persons who drink little or no alcohol. The etiology of NASH is unclear, but it is commonly associated with diabetes, obesity, and insulin resistance. Several pilot studies, including a study of pioglitazone at the NIH Clinical Center (01-DK-0130), have shown that the insulin-sensitizing thiazolidinediones lead to decreases in serum alanine aminotransferase (ALT) levels and improved liver histology. Once therapy is stopped, however, ALT levels rapidly return to pre-treatment values. Inaddition we are currently enrolling patients with NASH in a pilot study of metformin therapy for 48-weeks, however our results in 3 patients thus far have not been very encouraging. In the current study, patients who have completed the pilot study of pioglitazone and have been off therapy for 48 weeks will be offered re-treatment for 3 years. We also propose to treat patients who have not had a satisfactory response to metformin with pioglitazone for the same duration. After a repeat medical and metabolic evaluation and liver biopsy, patients with moderate-to-severe NASH (activity score greater than or equal to 4) will restart pioglitazone at a dose of 15 mg daily. If after 48 weeks, ALT levels are not normal or improved to the degree identified during the pilot study, the dose will be increased to 30 mg daily at the end of 3 years, all patients will undergo repeat medical and metabolic evaluation and liver biopsy. The primary end point will be improvement in liver histology. Secondary end points will be improvements in insulin sensitivity, reduction in visceral fat, liver volume, and liver biochemistry. The aim of this study is to evaluate whether long-term pioglitazone therapy can safely achieve and maintain biochemical and histological improvements in NASH.
