 AB    AIM: To compare the efficacy and safety of didanosine and zalcitabine in
       patients who could not tolerate zidovudine or who had failed to respond
       adequately. PATIENTS AND METHODS: A multicentre, randomly allocated,
       open-label clinical trial was set up with 230 patients treated with
       didanosine and 237 treated with zalcitabine. All had previously been
       treated unsuccessfully with zidovudine. The patients were followed for
       at least 1 year, with an average of 16 months. RESULTS: Disease
       progression or death occurred in 157 patients taking didanosine and 152
       taking zalcitabine. There appeared to be a slight trend in favour of
       survival in the latter group. CONCLUSIONS: There is an urgent need for
       more effective and better tolerated antiretroviral agents in the
       treatment of HIV infection. Zalcitabine is at least as effective as
       didanosine and may provide a survival advantage in patients treated
       unsuccessfully with zidovudine.
