ClinConnect Summary

Of the HIV-1 mutations reported to be associated with zidovudine resistance, the mutation at codon 215 of the reverse transcriptase gene is the most commonly occurring and has the greatest impact on susceptibility. When this mutation appears, a change in drugs may prevent further immunologic and virologic deterioration.

Initially, all patients receive AZT alone. After detection of a 215 mutation in plasma RNA, patients are randomized to one of three treatment arms: AZT alone, AZT plus ddI, or AZT/ddI plus nevirapine. Patients are followed every 8 weeks and receive treatment for up to 4 yea...
