Brief Summary:
The purpose of this study is to describe the effectiveness of darunavir/cobicistat (DRV/c)-based regimens, measured as maintenance of virological suppression 48 weeks after baseline, defined as the day when the treatment with DRV/c-based regimen is started, through collection of daily practice data in the Italian setting.

Group/Cohort
Cohort 1
HIV-1-infected patients being in stable ritonavir-boosted Antiretroviral (ARV) treatment with Protease Inhibitors (PIs) (either darunavir 800 milligram [mg] each day -based or not) since at least twelve months and virologically suppressed (HIV-RNA less than [<]50 copies/milliliters) since at least six months.



Primary Outcome Measures :
  1. Percentage of Patients With Human Immunodeficiency Virus - RiboNucleic Acid (HIV-RNA) Less Than (<)50 Copies/Milliliters (copies/mL) Measured at Week 48 [ Time Frame: At Visit 4 (Week 48) ]
    The percentage of patients with plasma HIV-RNA<50 copies/mL will be analyzed by FDA snapshot analysis (FDA Snapshot Approach is based on the last observed viral load data within the Week 48 window: virologic response is defined as HIV-1 RNA <50 copies/mL (observed case); If there are no data in the defined time window, the proportion of missing data and relative reason will be provided") and Time to loss of virologic response (TLOVR) method algorithm requires sustained HIV-1 RNA < 50 copies/mL; confirmed HIV-1 RNA more than or equal to (>=) 50 copies/mL is considered as non-response (rebound); patients considered non-responder after permanent discontinuation).


Secondary Outcome Measures :
  1. Change From Baseline in HIV-Symptoms Distress Module (HIV-SDM) Score [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    HIV-SDM is a questionnaire consisting of 20 questions related to all the symptoms which the patient might have had during the past four weeks. For each question patient has to select appropriate answer related to the symptoms: "0 = I do not have this symptom; 1 = I have this symptom and it doesn't bother me; 2 = it bothers me a little; 3 = it bothers me; 4 = it bothers me a lot".

  2. Change From Baseline in HIV-Treatment Satisfaction Questionnaire (HIV-TSQ) Score [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    The HIV Treatment Satisfaction Questionnaire (HIV-TSQ) is a 10-item instrument that is supported by evidence of good internal consistency reliability. The total score ranges from 0 to 60, with higher scores indicating greater treatment satisfaction. Score change ranges from -30 to +30, with scores<0 and >0 indicating a decrease and increase in treatment satisfaction, respectively.

  3. Percentage of Patients with HIV-RNA <50 copies/mL Measured at Week 24 [ Time Frame: At Visit 3 (Week 24) ]
  4. Change From Baseline in CD4 Cell Count [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    CD4 cell count will be assessed as immunological parameter.

  5. Change From Baseline in CD4/CD8 Ratio [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    CD4/CD8 ratio will be assessed as immunological parameter.

  6. Change From Baseline in CD4 Percentage [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    CD4 percentage will be assessed as immunological parameter.

  7. Change From Baseline in Creatinine Levels [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    The change from baseline in serum creatinine up to 48 weeks will be assessed.

  8. Change From Baseline in estimated Glomerular Filtration Rate (eGFR) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
    The change from baseline in eGFR will be assessed by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula.

  9. Change From Baseline in Aspartate Transferase (AST) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  10. Change From Baseline in Alanine-Amino Transferase (ALT) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  11. Change From Baseline in Gamma-Glutamyl Transferase (GGT) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  12. Change From Baseline in Alkaline Phosphatase (ALP) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  13. Change From Baseline in Total Cholesterol [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  14. Change From Baseline in Low Density Lypoprotein (LDL) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  15. Change From Baseline in High Density Lypoprotein (HDL) [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  16. Change From Baseline in Triglycerides [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
  17. Change From Baseline in Glucose [ Time Frame: Baseline, Up to Visit 4 (Week 48) ]
