  Purpose
The purpose of this study is to study the kinetics (study of the rate of change) of immune recovery quality and function in stored plasma blood samples of treatment-naive (not previously treated with antiretroviral drugs) patients with advanced human immunodeficiency virus (HIV) infection starting a Darunavir/Ritonavir- or Efavirenz-based highly active antiretroviral therapy (HAART) regimen.

Condition Intervention Phase
Human Immunodeficiency Virus; HIV Drug: Darunavir/Ritonavir (DRV/r) Drug: Efavirenz (EFV) Phase 4

Study Type: Observational
Study Design: Time Perspective: Retrospective
Official Title: Ex Vivo Study of Immune-Reconstitution Kinetics in HIV-infected ARV-naive Subjects, With Advanced Disease, Starting a Darunavir/Ritonavir or Efavirenz Based HAART (IMMUNO Study)

Primary Outcome Measures:
  • Change (>=10%) in the proportion of activated HLA-DR+CD38+CD8+ T-cells [ Time Frame: Baseline and Week 24 ]

Secondary Outcome Measures:
  • Change (>=10%) in the proportion of activated HLA-DR+CD38+CD8+ T-cells [ Time Frame: Baseline, Week 12, and Week 48 ]
  • Change in peripheral T-lymphocyte immune phenotype [ Time Frame: Baseline, Week 12, Week 24 and Week 48 ]
  • Change in peripheral T-lymphocyte turnover [ Time Frame: Baseline, Week 12, Week 24 and Week 48 ]

Enrollment: 33
Study Start Date: December 2011
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Darunavir/Ritonavir (DRV/r) Drug: Darunavir/Ritonavir (DRV/r)
Darunavir/Ritonavir (DRV/r) + Tenofovir/Emtricitabina regimen
Efavirenz (EFV) Drug: Efavirenz (EFV)
Efavirenz (EFV) + Tenofovir/Emtricitabina regimen

Detailed Description:

This is an ex-vivo study (study which takes place outside the organism and records immune parameters from stored blood and cells of a defined population without any intervention by the researcher) to evaluate the kinetics (study of the rate of change) of immune recovery quality and function in stored plasma blood samples of treatment-naive (not previously treated with antiretroviral drugs) patients with advanced human immunodeficiency virus (HIV) infection starting a Darunavir/Ritonavir (DRV/r)- or Efavirenz (EFV)-based highly active antiretroviral therapy (HAART) regimen. In previously stored plasma blood samples, the role of DRV/r compared with EFV in reducing T-lymphocyte activation, DRV/r compared with EFV in recovering T-lymphocyte immune phenotype in peripheral blood and thymic production, and DRV/r compared with EFV in recovering T-lymphocyte function (functional immunity) will be studied. Blood samples will be analyzed before (baseline) and up to 48 weeks after initiating HAART.

Each patient will receive orally administered (given by mouth) regimens of either Darunavir/Ritonavir (DRV/r) + Tenofovir/Emtricitabina or Efavirenz (EFV) + Tenofovir/Emtricitabina.
