Prevalence of Nonalcoholic Fatty Liver Disease (NAFLD) & Nonalcoholic

Status Completed

Clinical Trial Summary

Prospective determination of the prevalence of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH)in a primary care setting using ultrasound and percutaneous liver biopsy.

Clinical Trial Description

Patients between the ages of 18 and 70 years who are eligible for care at Brooke Army Medical Center are considered for enrollment. After obtaining informed consent, a baseline questionnaire is given to patients who present to the Primary Care Clinic for routine clinic visits or during colon cancer screening classes within the Gastroenterology Clinic. The questionnaire includes information about the patient's past medical history to include: known history of chronic liver disease, current medications, current and past alcohol ingestion, dietary habits that included consumption of fructose containing beverages and frequency of fast food visits. Patients are excluded if they are found to have a history of chronic liver disease, HIV, on medications that are associated with a fatty liver, or consumption of more than 20 grams of alcohol per day. Right upper quadrant ultrasound will then be performed to determine if there is evidence of fatty liver disease. All patients with a positive ultrasound for hepatic steatosis are then offered a liver biopsy after obtaining fasting blood work that included a complete blood count, coagulation studies, liver function tests, fasting lipid panel, glucose and insulin. Patients with a negative ultrasound for fatty liver are not referred for liver biopsy and are considered as completed study patients. Serum is also stored for adipokine and cytokine analysis. A study investigator using a 14g Bard Monopty biopsy gun will perform the liver biopsy. A single expert hepatopathologist will review all liver biopsies and utilize the Brunt system (9) for grading and staging of steatohepatitis if present. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
