BACKGROUND: Both highly potent antiretroviral drug rescue therapy and treatment interruption have been suggested to be effective in patients with multiple treatment failure. OBJECTIVE: To assess both the benefits and risks of an 8-week treatment interruption associated with a six to nine-drug rescue regimen in patients with multiple treatment failures. DESIGN: A randomized comparative controlled trial in 19 university hospitals in France. PATIENTS: Sixty-eight HIV-infected patients with multiple previous treatment failures and CD4 cell counts less than 200 x 10(6) cells/l andplasma HIV-1-RNA levels of 50,000 copies/ml or greater. MEASUREMENTS: The primary efficacy outcome was the proportion of patients with at least a 1 log10 decrease (copies/ml) in the plasmaHIV-1-RNA level after 12 weeks of therapy. RESULTS: Treatment interruption followed by multidrug salvage therapy led to a greater proportion of patients achieving virological success (i.e. 1 log10 decrease) at 12 weeks compared with patients receiving multidrug therapy alone (62 versus 26%, intent-to-treat analysis; P = 0.007). The median decrease in the HIV-1-RNA level was -1.91 and -0.37 log10 copies/ml (P = 0.008), respectively. Treatment interruption led to an increase in the number of sensitive drugs of the multidrug regimen (71 versus 35% of regimen with at least two sensitive drugs; P = 0.004). Factors associated with virological success were treatment interruption, the reversion of at least one mutation to wild type, adequate plasma drug concentration, and the use of lopinavir. CONCLUSION: Treatment interruption was beneficial for treatment-experienced HIV-infected patients with advanced HIV disease and multidrug-resistant virus.
