Specifically, to determine, in patients who have been taking zidovudine (AZT) alone for a long time, whether it is beneficial to add lamivudine (3TC) to AZT or to switch to d4T alone, and also to determine, in patients who have been taking didanosine (ddI) alone for a long time, whether it is beneficial to add AZT or AZT/3TC to ddI.\n\nCharacteristics of virus replication, pathogenicity, and resistance are thought to determine the durability of virologic and clinical response to nucleoside reverse transcriptase inhibitors.
