Lopinavir/r monotherapy cannot be considered non-inferior to EFV/FTC/TDF. PI resistance rarely emerged in the lopinavir/r arm and did not undermine future PI options. Two years of lopinavir/r monotherapy had no deleterious clinical impact when compared with EFV/FTC/TDF.

In patients with high nadir and current CD4 cell counts, 2 year I-ART maintained the CD4 cell count above 500/mm(3), with no increase in the viral reservoir. Immune activation seems related to HIV replication, while inflammation seems to evolve independently and require specific attention.
