Primary Outcome Measures:

Percentage of Participants With Human Immunodeficiency Virus -1 Ribonucleic Acid (HIV-1 RNA) <50 Copies/mL [ Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 ] [ Designated as safety issue: No ]
Viral load (number of HIV-1 RNA copies in the blood) was measured at baseline and scheduled study visits. A decrease in viral load is a measure used to assess the effectiveness of antiviral treatments. The percentage of participants with HIV RNA less than 50 copies/mL at each time point is presented.

Secondary Outcome Measures:

Change From Baseline in Absolute CD4 Cell Count [ Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 ] [ Designated as safety issue: No ]
Increases in CD4 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD4+ cells at scheduled study visits.
Change From Baseline in Relative CD4 Cell Count [ Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 ] [ Designated as safety issue: No ]
Increases in relative CD4 count (the percentage of total lymphocytes that are CD4 cells) are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the percentage of CD4+ cells at scheduled study visits.
Change From Baseline in Absolute CD8 Cell Count [ Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 ] [ Designated as safety issue: No ]
Decreases in CD8 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD8-positive (CD8+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD8+ cells at scheduled study visits.
Change From Baseline in Relative CD8 Cell Count [ Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 ] [ Designated as safety issue: No ]
Decreases in relative CD8 count (the percentage of total lymphocytes that are CD8 cells) are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD8-positive (CD8+) T-lymphocyte counts were assessed by measuring the change from Baseline in the percentage of CD8+ cells at scheduled study visits.
Change From Baseline in CD4/CD8 T-cell Ratio [ Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144 ] [ Designated as safety issue: No ]
The CD4/CD8 T-cell ratio, also known as the T-lymphocyte helper/suppressor profile, presents the number of lymphocytes in the blood positive for CD4 cells compared with the number positive for CD8 cells. Changes in participants' CD4/CD8 T-lymphocyte ratio were assessed by measuring the change from Baseline in the ratio at scheduled study visits.


Enrollment:	65
Study Start Date:	January 2004
Study Completion Date:	September 2011
Primary Completion Date:	September 2011 (Final data collection date for primary outcome measure)

Groups/Cohorts
HIV-infected participants HIV-infected participants taking lopinavir/ritonavir (Kaletra) and one other protease inhibitor. Lopinavir/ritonavir (Kaletra) dosing and administration according to the Summary of Product Characteristics (three 133 mg/33 mg capsules twice daily or two 200 mg/50 mg tablets twice daily).

Detailed Description:

This study is intended to observe and collect data on the usage, dosing, tolerability, and effectiveness of lopinavir/ritonavir (Kaletra) when used as part of a Nucleoside Reverse Transcriptase Inhibitors-free double protease regimen. Enrollment in the study was independent of the decision to prescribe Kaletra.
