Abstract:

The impact of long-term changes in plasma viremia, produced by effective combination antiretroviral therapy, on human immunodeficiency virus (HIV) burden within tissue reservoirs is unknown. Fifteen patients who had received at least 1 year of therapy with two or three drug combinations of zidovudine, didanosine, and nevirapine had suitable samples of lymph node tissue obtained by ultrasound-guided core needle biopsy. HIV RNA was extracted from homogenized tissue samples and quantitated using a modified branched DNA assay. Results were correlated with antiretroviral treatment effect on the basis of plasma virus load measurements over the preceding 12-18 months. A statistically significant negative correlation was observed between magnitude of treatment effect on plasma viremia and lymph node virus load. These data suggest that combinations of antiretroviral drugs that produce sustained suppression of plasma HIV RNA may also be able to reduce the virus burden in lymphoid tissues.
