OBJECTIVE: To assess the efficacy of combination therapy that includes ritonavir in HIV-1 infected children. DESIGN: A monocentric retrospective study. PATIENTS AND METHODS: Twenty-two children with a minimum follow-up of 6 months under triple therapy including ritonavir were analysed for treatment efficacy. At entry, all the patients were protease inhibitor naive and all but two had received previous antiretroviral therapy during a median period of 5 years. Their initial median CD4+ lymphocyte count and viral load were 121 x 10(6)/l and 5.08 log10 copies/ml, respectively. Clinical and biological evaluation included clinical assessment every 6 weeks and determination of CD4 cell count and HIV-RNA concentration every 3 months. RESULTS: Median length of follow-up on triple therapy was 15 months (range: 7-21 months). Neither progression in the CDC classification nor death occurred. No significant change in mean weight SD scores was noted when baseline values were compared with values obtained after 1 year of triple therapy. Median CD4 count increases were of 210 x 10(6)/l, 415 x 10(6)/l, and 472 x 10(6)/l cells at 6, 12, and 18 months, respectively. Among the patients baseline characteristics, neither age nor initial CD4 cells count influenced the magnitude of immunologic improvement. There were median decreases of 1.14, 0.95, and 1.5 log10 per ml of plasma in the concentration of viral RNA at 6, 12, and 18 months respectively. Seven patients maintained an undetectable viral load when under treatment. The introduction of at least one new reverse transcriptase inhibitor at the initiation of triple therapy correlated significantly with a greater viral suppression. CONCLUSION: Despite variable viral response, antiretroviral-experienced HIV-infected children demonstrated a substantial CD4 cell increase during a median period of 15 months of ritonavir containing combination therapy. |
