The insufficient suppression of viral load by saquinavir hard gel is reversible: a retrospective cohort study.

Abstract:

PURPOSE:To assess the effect of changing antiretroviral therapy in patients initially treated with saquinavir hard gel capsule (hgc). METHOD:A retrospective cohort study comparing the virological and immunological responses in antiretroviral-naïve patients initially treated with a regimen of saquinavir-hgc, zidovudine, and lamivudine, with patients receiving either ritonavir or indinavir on a background of zidovudine and lamivudine. RESULTS:Twenty-nine patients starting with saquinavir-hgc as the protease inhibitor (PI) component were compared to 58 patients starting with ritonavir (n = 16) or indinavir (n = 42). Median follow-up time was 30 and 33 months, respectively. Twelve, 18, 24, and 30 months after starting a regimen including saquinavir-hgc, 72%, 50%, 4%, and 0% of patients still received this PI. At these time points, 35%, 24%, 59%, and 74% of the patients in the saquinavir group obtained an HIV-RNA <500 copies/mL compared to 76%, 72%, 66%, and 65% in the indinavir/ritonavir group. No significant difference in CD4 count between the two groups was observed. CONCLUSION:We found that saquinavir-hgc, in combination with nucleoside reverse transcriptase inhibitors, suppressed viral load insufficiently in HIV patients naïve to antiretroviral therapy. However, the suboptimal effect of saquinavir-hgc seems reversible after optimizing the antiretroviral regimen, at least for the short term.
