    Abstract:
    25 HIV-infected antiretroviral-naive adults were included in a 24-week study to evaluate the efficacy and the tolerability of a zidovudine/didanosine combination therapy in which didanosine was administered once daily (200 mg if weight < 60 kg, 300 mg if weight > 60 kg) and zidovudine twice daily (500 mg/day if weight < 90 kg, 600 mg/day if weight > 90 kg). 5 patients discontinued their treatment early: 3 had poor compliance and 2 presented adverse events. Evaluation of treatment efficacy was based on CD4+ T cell enumeration and HIV RNA level quantitation in plasma (NASBA). Baseline values were 278 CD4+/mm3 and 5.42 log RNA copies/ml. Mean changes from baseline were +102 CD4+/mm3 and -2.14 log RNA copies/ml at week 8 and +156 CD4+/mm3 and -2.07 log RNA copies/ml at week 24. HIV RNA in plasma was lower than the detection limit (2.60 log RNA copies/ml) in 55% of patients at week 8 and in 30% at week 24. No major adverse events such as neuropathy or pancreatitis were observed. Once-daily administration of didanosine in combination with twice-daily administration of zidovudine is a well tolerated regimen that appears to be as effective ad the conventional zidovudine/didanosine combination regimen.
