Primary Outcome Measures:
  • Proportion of patients remaining on ATV-based treatment over time [ Time Frame: Up to 5.5 years ]
    Every 6 months from ATV initiation till July 2013 at the latest (maximum follow-up time up to 5.5 years)

Secondary Outcome Measures:
  • Time to discontinuation of ATV [ Time Frame: Every 6 months up to 5.5 years ]
  • Reasons for ATV discontinuation [ Time Frame: Every 6 months up to 5.5 years ]
  • Percent of patients with HIV-1 ribonucleic acid (RNA) < 50 and < 500 c/mL [ Time Frame: Every 6 months up to 5.5 years ]
  • Mean change in HIV-1 RNA [ Time Frame: Every 6 months up to 5.5 years ]
  • Time to viral failure (HIV-1 RNA ≥ 50 and ≥ 500 c/mL) [ Time Frame: Every 6 months up to 5.5 years ]
  • Mean change in Cluster of differentiation 4 (CD4) cell count [ Time Frame: Every 6 months up to 5.5 years ]
  • Adverse events (AEs) related to ATV [ Time Frame: Every 6 months up to 5.5 years ]
  • Lipid profile [ Time Frame: Every 6 months up to 5.5 years ]

ARV-naïve HIV patients initiated on ATV/RTV-based therapy

Anti-retroviral (ARV)-naïve HIV patients initiated on ATV/RTV-based therapy between 2008-2010

One cohort being observed for 3 different countries

Detailed Description:

Time perspective: Collection of historical data and longitudinal follow up. Patients will be enrolled in 2011/2012 but data will be collected from medical charts from ATV initiation date (Feb 2008 - July 2010) until July 2013 at the latest (if no ATV discontinuation, or death, or lost to follow up).

Non probability sample:

  • Specialized HIV management centers will be contacted in order to recruit about 15-20 sites per country.
  • Each site will have to enroll an average of 8-12 consecutive patients (min:5; max:30) fulfilling the inclusion/exclusion criteria.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients attending HIV specialized management centers will be considered.

Inclusion Criteria:

  • Male or Female HIV patients ≥ 18 years old at ATV/RTV initiation treatment date
  • Outpatient seen in routine consultation whatever the reason, between January 1st 2011 and March 31st 2012
  • Commencing an ATV/RTV-based regimen including at least 2 nucleoside reverse transcriptase inhibitors (NRTI) after February 1st 2008 and before July 31st 2010, regardless of the current ARV treatment ongoing at enrollment visit

Exclusion Criteria:

  • Patient exposed to or who began ATV/RTV prior to February 1st 2008, or after July 31st 2010 or without a known start date for ATV/RTV therapy
  • Exposure to more than 4 weeks of any ARV prior to initiation of ATV/RTV treatment
  • Participation in a clinical trial with ATV at the time of or after initiation of ATV/RTV-based regimen
