A Study of Zidovudine in HIV-Infected Patients With Liver Disease

Completed · Not applicable

Conditions studied: HIV Infections, Liver Diseases

In brief

To examine the pharmacokinetics (blood levels) and bioavailability of zidovudine (AZT) given to patients with HIV infection and chronic liver disease. The specific aim of the study is to provide data permitting the development of guidelines for use of AZT in patients with mild, moderate, or severe liver disease. AZT is the only antiviral agent that has been shown to be effective in patients with severe HIV infection. However, AZT is largely eliminated from the body through a biochemical reaction that takes place in the liver, and it is possible that patients with underlying liver disease may have altered AZT pharmacokinetics and may metabolize AZT differently, with the result that they are susceptible to an increased risk of serious drug toxicity. This study will examine the pharmacokinetics, elimination, and metabolism of AZT in patients with liver disease. Guidelines developed from the data will be helpful in managing AZT treatment of these HIV-infected persons and will indicate whether the dose of AZT administered should be adjusted to compensate for any changes in its bioavailability and/or pharmacokinetics.

No medications should be taken for 48 hours prior to entering the study. Hemophiliacs are included.
• Prior Medication:
• Allowed:
• Zidovudine (AZT) if discontinued at least 48 hours prior to study entry.

You may not qualify if…

• Co-existing Condition:
• Patients will be excluded from the study if unacceptable toxicity develops or if an illness requiring concurrent treatment develops.
• Concurrent Medication:
• Excluded within 48 hours of study entry:
• All medications. Medication may be resumed after completion of day 2 of the study.
• Concurrent Treatment:
• Excluded within 48 hours of study entry:

• Presence of active opportunistic infections, with the exception of active or chronic hepatitis B virus or hepatitis D virus infection, or ongoing therapy for an opportunistic infection.
• Thrombocytopenia, with platelets less than 50000 platelets/mm3.
• Neutropenia, with polymorphonuclear leukocytes less than 1000 cells/mm3.
• Renal insufficiency, with creatinine greater than 1.5 mg/dl.
• Acute viral hepatitis within 30 days of the study.
• Patients who are expected to be noncompliant or who are unwilling to sign an informed consent statement.
• Prior Medication:
