title: Residual human immunodeficiency virus type 1 RNA in lymphoid tissue of patients with sustained plasma RNA of <200 copies/mL.
abstract: Human immunodeficiency virus type 1 (HIV-1) RNA was measured in lymph node (LN) mononuclear cells of 50 patients with sustained plasma RNA of <200 copies/mL with therapy. Six patients had received a combination of three reverse transcriptase inhibitors (RTIs) since primary infection, 11 received this same combination during chronic disease, 21 received a combination of two RTIs plus a protease inhibitor (PI), and 12 received three RTIs plus a PI. The mean overall duration of therapy was 8.9 +/- 0.5 months (range, 5-24), with no significant difference between groups. LN HIV-1 RNA levels varied from undetectable to 1.7 million copies/10(6) cells according to cases. The mean LN HIV-1 RNA level was 2.99 +/- 0.42 log10 copies/10(6) cells in the 17 patients receiving three RTIs compared with 1.93 +/- 0.25 log10 copies/10(6) cells in the 33 patients receiving a PI (t test, P = .02). These data demonstrate that highly active antiretroviral regimens have unequivalent effects on LNs and invite redefinition of suboptimal therapy at this level.
