Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Although plasma viral load drops dramatically after initiation of powerful antiretrovirals, it does not drop to zero. It appears that a new steady state is reached, suggesting that a reservoir may exist of virus-producing cells, possibly cells of monocyte/macrophage lineage, that continue to produce a low level of virus despite antiretroviral treatment.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients undergo 5 weeks of antiretroviral washout before initiating therapy with ritonavir alone for 9 days, followed by combination therapy with ritonavir, zidovudine, and lamivudine from day 10 through week 48. \[AS PER AMENDMENT 1/31/97: The availability of the current, open-label study treatment has been extended to allow patients who have completed 48 weeks of therapy to continue protocol therapy until the last enrolled patient completes 48 weeks of study treatment.\]

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
Allowed:

Patients must have:
* Documented HIV infection.
* CD4 count 100-300 cells/mm3.
* At least 3 consecutive months of prior AZT at a dosage of 500-600 mg bid, but with 5 weeks of antiretroviral washout prior to study entry.

Exclusion Criteria
Patients with the following symptoms or conditions are excluded:
