Brief 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 be given a sedative for the procedure.
- Follow-up visits. Patients return for follow-up visits 1 to 4 weeks after the liver biopsy and three more times over the course of the study for a medical history, physical examination and blood tests. Patients may participate in an additional 4-year follow-up, during which they have visits every 3-12 months and are offered the opportunity to repeat the biopsy no sooner than 1 year after the first biopsy.

Eligibility Criteria
HIV-infected patients with chronically elevated transaminases while on c/ARV medications or not on c /ARV medications that agree to research procedures that investigate the prevalence of hepatic fibrosis in the absence of hepatitis B or C co-infection@@@
You may qualify if:
- Age 18 years or older.
- Ability to understand and willingness to provide written informed consent.
- Willingness to undergo liver biopsy.
- Willingness to comply with study requirements and procedures including storage of blood and liver tissue samples for use in future studies of HIV, AIDS, immune function, hepatic diseases, or other related diseases.
- Established HIV diagnosis (documentation of HIV-1 infection by licensed ELISA testing and confirmed by Western Blot).
- For the antiretroviral cohort on combination antiretroviral therapy for at least 12 months with stable regimen for at least 3 months prior to enrollment.
- Chronically elevated transaminases for at least 6 months documented by an elevated AST and/or ALT on the following 3 occasions within the 12 months prior to enrollment:
