Brief summary

Therapy with lopinavir/ritonavir (Kaletra) and one other protease inhibitor in Human Immunodeficiency Virus participants

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.
