A Comparison of Zidovudine Plus Lamivudine Versus ddI Used Alone or in Combination With Zidovudine in HIV-1 Infected Children

To compare the efficacy of lamivudine (3TC) and zidovudine (AZT) in combination versus the better of didanosine (ddI) monotherapy or ddI/AZT combination, in symptomatic HIV-1 infected children who received less than 56 days of prior antiretroviral therapy. To evaluate the safety and tolerance of 3TC/AZT in this patient population. To determine other measures of diseases in response to the study regimens. Currently, none of the potential treatments for HIV-1 infection has proven to be both nontoxic and effective in long-term use. However, previous studies in both adults and children have shown that 3TC combined with AZT reduced HIV load in blood and increased white blood cells. Additionally, 3TC has demonstrated a favorable safety profile.
