Purpose
To evaluate the relationship between plasma and intracellular darunavir (DRV) concentrations and virological efficacy in HIV-infected patients on DRV/rtv monotherapy.
| Condition | Intervention |

| HIV-infection | Drug: Darunavir/ritonavir |
| Study Type: | Observational |
| Study Design: | Observational Model: Cohort Time Perspective: Prospective |

Primary Outcome Measures:
- Virological efficacy [ Time Frame: 48 and 96 weeks ]To correlate the plasma and intracellular (cell-associated)) DRV levels with the virological efficacy analyzed by the time to loss of virological response (TLOVR) algorithm, considering VF as either: 1) two consecutive viral load >200 copies/mL, 2) a unique HIV-RNA >200 copies/mL if followed by lost to follow-up, or 3) the reintroduction of nucleos(t)ides because any reason.
Secondary Outcome Measures:
- Impact of viral breakthrough on DNA-HIV reservoirs and immunologic activation [ Time Frame: 48 and 96 weeks ]Impact of blips and persistent viraemia on DNA-HIV reservoirs and immunologic activation

Darunavir-ritonavir monotherapy
HIV-infected patients with undetectable viral load for at least for 6 months on stable therapy and no darunavir related mutations in the HIV-protease gene
|
Drug: Darunavir/ritonavir
Darunavir/ritonavir (800/100 mg once daily) monotherapy
Other Name: Prezista/norvir
|
Detailed Description:
To be enrolled, subjects had a plasma HIV-RNA <50 copies/mL for at least 6 months based, virologic failure while on a PI-containing regimen was allowed if the genotypic resistance tests showed no major resistance mutation associated to reduced susceptibility to DRV/rtv according to the International AIDS Society. Patients with transitory episodes of detectable plasma HIV-RNA viral load ("blip") preceded and followed by a plasma viral load <50 copies/mL without changes in antiretroviral treatment could also been included. The only exclusion criteria were pregnancy, hepatitis B coinfection and the concomitant use of drugs with potential major interactions with DRV/rtv pharmacokinetics.
Eligibility| Ages Eligible for Study: | 18 Years to 65 Years (Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Non-Probability Sample |
Study Population
HIV-infected patients who started an antiretroviral regimen based on darunavir-ritonavir (800/100 mg) once daily monotherapy between June 2010 and September 2010
Criteria
Inclusion Criteria:
- Older than 18 years, starting an antiretroviral regimen based on darunavir-ritonavir (800/100 mg) once daily monotherapy between June 2010 and September 2010
- Plasma RNA-VIH < 50 copies/ml on stable antiretroviral treatment for ≥ 6 months
- Absence of resistance mutations in the protease gene, based on treatment history and/or genotypic resistance testing. that would decrease darunavir susceptibility
Exclusion Criteria:
- Pregnancy
- Chronic B hepatitis
- Genotypic resistance tests with evidence of resistance mutations in the protease gene that would decrease darunavir susceptibility
- Concomitant use of drugs with potentially adverse interactions with darunavir-ritonavir pharmacokinetics, such as rifampin
