  Purpose

This is a open controlled trial in which 48 HIV-1 patients successfully treated with EFV/FTC/TDF will be randomized to one of 4 groups in equal proportion between arms (1:1). The four arms are as follows:

Arm I: EFV / FTC / TDF (n = 12) Arm II: EFV / FTC / TDF + LST (n = 12) Arm III: FTC / TDF + MK-0518 (n = 12) Arm IV: FTC / TDF + LST + MK-0518 (n = 12)

The allocation will take place in two phases:

Phase I: 24 patients 1:1 receiving EFV/FTC/TDF vs. EFV/FTC/TDF + Losartan

If losartan arm shows benefits we will proceed to the second phase:

Phase II: 24 patients 1:1 to receive FTC/TDF+ MK-0518 versus FTC/TDF + MK-0518 + losartan.

Patients will be followed up during 12 months to determinate the proportion of patients with decreased collagen deposition in TL equal to or greater than 50%.

  • Proportion of patients with undetectable plasma viral load and decreased in lymphatic tissue in different groups [ Time Frame: VL in plasma: 12, 24, 36, 48 weeks, Lymphatic tissue: week 48 ] [ Designated as safety issue: Yes ]
  • Proportion of patients with changes in the CD4/CD8 ratio in peripheral blood in different groups. [ Time Frame: 12, 24, 25 and 48 weeks ] [ Designated as safety issue: Yes ]
  • Proportion of patients with reduced intima-media complex in carotid ultrasound in different groups. [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
  • Proportion of patients with changes in levels of metalloproteinases and their inhibitors, beta2-microglobulin and CSF cells and proteins. [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
  • Proportion of patients with improvement in neuropsychological test CDS [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
  • Incidence and types of adverse events and laboratory abnormalities in the different groups. [ Time Frame: 12, 24, 36 and 48 weeks ] [ Designated as safety issue: Yes ]
