Title: Factors predictive of virological failure on atazanavir in 310 HIV-infected patients. Author: Lescure FX, Poirier JM, Meynard JL, Guiard-Schmid JB, Zouai O, Bonnard P, Slama L, Amiel C, Girard PM, Pialoux G. Journal: AIDS; 2010 Jun 19; 24(10):1593-5. PubMed ID: 20539093. Abstract: We examined factors associated with virological failure in 310 HIV-infected patients receiving atazanavir (ATV). Independent links were identified with virological failure under ATV: virological failure previous history (P = 0.006) and ATV underdosing (P = 0.04). A maintenance therapy was protective (P = 0.01). The optimal therapeutic ranges of ATV concentration were found to be from 300 ng/ml (or 180 for patients treated with maintenance therapy) to 650 ng/ml for C24 and from 1000 ng/ml (or 500 for patients treated with maintenance therapy) to 2000 ng/ml for C12.[Abstract] [Full Text] [Related] [New Search]
