Objective: To assess the antiretroviral effect of a combination of zidovudine, didanosine, lamivudine and saquinavir in plasma, peripheral blood mononuclear cells (PBMC) and lymph‐node mononuclear cells (LNMC) after 8 weeks. Methods: Ten HIV‐1 antiretroviral therapy‐naive patients were given a combination of oral zidovudine (200 mg three times daily), oral didanosine (200 twice a day), oral lamivudine (150 mg twice a day) and oral saquinavir (600 mg three times daily). HIV‐1 plasma RNA was measured by quantitative reverse transcriptase (RT)‐polymerase chain reaction (PCR). Infectious HIV‐1 in PBMC and LNMC was measured by a coculture technique. HIV‐1 RNA in PBMC and LNMC was quantified by RT‐PCR. Proviral DNA titres in PBMC and LNMC were measured by endpoint dilution PCR. CD4 T‐cells were analysed by flow cytometry. Results: CD4 cell counts rose in all patients (mean increase of 125 ± 71 CD4 cells × 106/l) and the benefit was greater for patients with fewer than 350 CD4 cells × 106/l (mean increase of 159 ± 74 CD4 cells × 106/l). Plasma HIV‐1 RNA decreased exponentially in all patients (mean decrease of 3.1 log10 after 8 weeks with a mean half‐life of 2.2 ± 0.6 days). HIV‐1 RNA showed a decrease of 3.07 log10 in PBMC and of 2.1 log10 in LNMC. The decrease in plasma HIV‐1 RNA was consistently associated with the decrease in LNMC. These data were supported by a concomitant drop of HIV‐1 infectious titres in PBMC (mean decrease of 1.41 log10) and in LNMC (mean decrease of 2.54 log). Conclusions: These data show a significant antiretroviral effect of this four‐drug combination in blood and lymphoid tissues. However, a greater decrease in HIV‐1 RNA was observed in PBMC and in plasma than in lymph node cells.
