Cell‐Associated HIV‐1 RNA in Blood as Indicator of Virus Load in Lymph Nodes


Yerly, S; Rutschmann, O T; Opravil, M; Marchal, F; Hirschel, B; Perrin, L (1999). Cell‐Associated HIV‐1 RNA in Blood as Indicator of Virus Load in Lymph Nodes. Journal of Infectious Diseases, 180(3):850-853.

Abstract

We have developed sensitive assays for viremia and cell-associated human immunodeficiency virus type 1 (HIV-1) RNA and DNA to assess the predictive value of virological parameters determined in blood for virus load in lymph nodes (LNs). Eighteen patients were included; 13 received stavudine/didanosine/hydroxyurea and 5 stavudine/didanosine, and all had viremia <500 copies/mL for >3 months. At the time of LN biopsy (median, 10 months), the median viremia was 2.09 log copies/mL (range, <0.70-3.34). Cell-associated HIV-1 RNA and DNA were detectable in blood and LNs of all patients. The median cell-associated RNA and DNA were 2.16 log copies/106 cells and 2.60 log copies/106 cells in blood versus 4.31 log RNA copies/106 cells and 3.26 log DNA copies/106 cells in LNs. Regression analysis shows that, in treated patients with sustained low viremia, cell-associated RNA and DNA in blood are better predictors of virus load in LNs than viremia
