Teacher: Now, understand the problem? Solve this instance: Question: Does the level of persistent HIV viremia increase after successful simplification of maintenance therapy to lopinavir/ritonavir alone?
Answer: The level of persistent viremia did not increase after stopping NRTI therapy among subjects who maintained virus suppression < 50 copies/ml on LPV/r alone through 48 weeks. This supports further studies of induction-simplification therapy for treatment of HIV-1 infection including the identification of factors predicting success or failure of simplified therapy.
