## Abstract Many AIDS patients retain high CD4+ Tβcell counts despite a significant increase in PCR viral load after varied periods of treatment on drug combination with Highly Active Antiretroviral Therapy (HAART). In order to investigate this contradictory phenomenon, we assayed for infectious HI

β¦ Synopsis
Human immunodeficiency virus type 1 (HIV-1) infected patients treated with combination antiretroviral therapy frequently have the level of HIV-1 RNA detectable in plasma driven below the lower limit of detection of current assays, 50 copies ml(-1). Patients may continue to exhibit viral loads (VLs) below the assay limit for years, yet on some occasions the VL may be above the limit of detection. Whether these 'blips' in VL are simply assay errors or are indicative of intermittent episodes of increased viral replication is of great clinical concern. By analyzing the occurrence of viral blips in 123 treated HIV-infected patients, we show that patients do not share a common probability distribution of blip amplitude and thus reject the hypothesis that blips are solely due to assay variation.

## Abstract To analyze the clinical relevance of AZT resistance mutations in AZTβnaive patients, 56 HIVβ1 seropositive patients treated for 18 months with stavudine/lamivudine (27 patients) or AZT/lamivudine (29 patients) were studied. AZTβlike resistance mutations were found in 13 out of 29 (44%)
During a randomized double-blind study to assess the antiviral activity of saquinavir (SQV) alone or in combination with zidovudine (ZDV), the emergence of phenotypic resistance was evaluated in 44 patients treated with SQV (13 subjects), ZDV (14 subjects), and SQV plus ZDV (17 subjects). A signific
