Liver Fibrosis in HIV-Infected Patients With Elevated Liver Enzymes on Antiretroviral Therapy
NCT00326482 · View on ClinicalTrials.gov ↗
Study Summary
This study will provide a basis for research on the impact of liver injury caused by antiretroviral therapy in HIV-infected patients. Elevated liver enzymes called AST and ALT are common in HIV-infected patients taking antiretroviral medications and can indicate liver damage. Although there are a number of possible causes for these elevations, such as infections with a hepatitis virus, antiretroviral medications alone can lead to the elevations. The study will focus particularly on evidence of liver fibrosis, which is a sign of progressive liver damage. HIV-infected patients 18 and older who 1) have been taking combination antiretroviral therapy for at least 12 months and have been on a stable regimen for at least 3 months, and 2) have had elevated AST or ALT levels for at least 6 months may be eligible for this study. Patients who have had liver biopsies performed in the past may be eligible for participation. Participants undergo the following tests and procedures over a 12-month period: * Oral glucose tolerance test: The patient drinks a glucose (sugar) drink. Blood samples are then drawn over 2 hours through an intravenous (IV) line in the patient's arm. This test measures how high the patient's blood sugar and insulin levels rise after drinking a standard glucose load. * Transient elastography: This ultrasound test uses vibration (sound waves) to measure liver stiffness (fibrosis). Vibrations move faster through a fibrotic liver. * Triple-phase CT scan and single slice CT scan of L4-5: Patients fast for 4 hours before the CT scan. A contrast material is injected through a catheter placed in an arm vein to improve the visibility of the liver in the specialized X-ray images obtained in the CT scanner. * Liver biopsy: This test removes a small sample of liver tissue for microscopic examination, particularly for evidence of fibrosis. The skin over the biopsy site is numbed and a needle is passed through the skin and rapidly in and out of the liver. Patients may

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00326482
The ClinicalTrials.gov registry entry for NCT00326482 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 127 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Liver Fibrosis appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00326482 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
