KaleEAST is a non-interventional, post-marketing observational study (PMOS) in which lopinavir/ritonavir is prescribed in the usual manner in accordance with the terms of the local marketing authorization with regards to dose, population and indication. No additional procedures (other than the standard of care) are to be applied to the patients.
The KaleEAST PMOS was conducted in a prospective, single-arm, multicountry, multicenter format. The study was carried out in two (2) parts: the first part was initiated in 2004 with the lopinavir/ritonavir capsule formulation, the second part started in 2006 after the lopinavir/ritonavir tablets had become available in the participating countries.
The aim of this post-marketing observational study was to obtain further data on clinical, biological, and virological outcomes, compliance and tolerability of Kaletra®-containing regimen during routine clinical use in the participating countries.

- CD4 Count [ Time Frame: Baseline ]CD4 lymphocyte count is a measure of a participant's immunologic health. Participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the number of CD4+ cells at baseline.
- Changes in CD4 Count [ Time Frame: Baseline to 1 month ]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.
- Changes in CD4 Count [ Time Frame: Baseline to 3 months ]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.
- Changes in CD4 Count [ Time Frame: Baseline to 6 months ]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.
- Changes in CD4 Count [ Time Frame: Baseline to 9 months ]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.
- Changes in CD4 Count [ Time Frame: Baseline to 12 months ]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.
- Changes in CD4 Count [ Time Frame: Baseline to 15 months ]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.
- Changes in CD4 Count [ Time Frame: Baseline to 18 months ]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.
- Viral Load [ Time Frame: Baseline ]Viral load is a direct measure of the viral burden by providing a count of the number of HIV-RNA copies in blood (plasma). The number of HIV-RNA copies in the blood was measured at baseline.
- Viral Load [ Time Frame: 1 month ]Viral load (number of HIV-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.
- Viral Load [ Time Frame: 3 months ]Viral load (number of HIV-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.
- Viral Load [ Time Frame: 6 months ]Viral load (number of HIV-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.
- Viral Load [ Time Frame: 9 months ]Viral load (number of HIV-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.
- Viral Load [ Time Frame: 12 months ]Viral load (number of HIV-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.
- Viral Load [ Time Frame: 15 months ]Viral load (number of HIV-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.
- Viral Load [ Time Frame: 18 months ]Viral load (number of HIV-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.
- Laboratory Parameter Blood Glucose [ Time Frame: Baseline, 9 months, 18 months ]Blood glucose laboratory values were assessed at baseline and scheduled study visits. Normal ranges are based on the standards for individual facilities in each country.
- Laboratory Parameter Transaminases [ Time Frame: Baseline, 9 months, 18 months ]Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) laboratory values were assessed at baseline and scheduled study visits. Normal ranges are based on the standards for individual facilities in each country.
- Laboratory Parameter Lipids [ Time Frame: Baseline, 9 months, 18 months ]A blood lipid panel consisting of total cholesterol, triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) levels was performed at baseline and scheduled study visits. Normal ranges are based on the standards for individual facilities in each country.
- Reasons for Discontinuation of Lopinavir/Ritonavir [ Time Frame: 9 months ]For participants who discontinued lopinavir/ritonavir treatment, the reasons for discontinuation are provided.
- Reasons for Discontinuation of Lopinavir/Ritonavir [ Time Frame: 18 months ]For participants who discontinued lopinavir/ritonavir treatment, the reasons for discontinuation are provided.
- Compliance With Lopinavir/Ritonavir [ Time Frame: 9 months ]Participants reported whether they had missed doses of their antiretroviral treatment.
- Compliance With Lopinavir/Ritonavir [ Time Frame: 18 months ]Participants reported whether they had missed any doses of their antiretroviral treatment.
- Adverse Events Observed on Treatment With Lopinavir/Ritonavir. [ Time Frame: 18 months ]
Total number of adverse events with causal relationship (rated by Investigator as probably or possibly related) to lopinavir/ritonavir treatment.
All serious adverse events and non serious adverse events (0.2% or greater frequency) are summarized in the "Reported Adverse Events" section of this record.
