AB Human immunodeficiency virus type 1 (HIV-1) isolates from 2 patients who
received didanosine (ddI) monotherapy for > 2 years were analyzed for
reverse transcriptase (RT) mutations by sequencing of proviral DNA from
peripheral blood mononuclear cell cultures. One patient was otherwise
antiretroviral-naive; the other had received zidovudine for 5 months
before beginning ddI therapy. Isolates obtained from both patients
before initiation of ddI monotherapy were free of HIV-1 RT mutations
associated with zidovudine or ddI resistance. However, after prolonged
ddI monotherapy, mutations associated with zidovudine resistance (M41L,
D67N, K70R, and/or T215Y) were detected in HIV-1 isolates from both
patients. There was no evidence that surreptitious use of zidovudine or
technical artifact caused these findings. This observation suggests that
prolonged ddI monotherapy may decrease the efficacy of subsequent
zidovudine therapy in some patients.
