AB Treatment of human immunodeficiency virus (HIV) infection with
nevirapine in patients with < 400 CD4 cells/mm3 rapidly selects for
virus with reduced susceptibility to nevirapine. To test whether
resistance would develop less quickly in patients with a lower virus
burden, nevirapine was studied in asymptomatic patients with > 500 CD4
cells/mm3. With 400 mg of nevirapine daily, the median reduction in HIV
RNA was 0.51 log10 copies/mL, and all isolates recovered by 12 weeks
were resistant to nevirapine. As in patients with lower CD4 cell counts,
some patients experienced sustained reduction in plasma HIV RNA despite
the presence of resistant virus. These results suggest that lower levels
of HIV RNA and immunosuppression did not retard the rate of emergence of
nevirapine-resistant virus; also, a polymerase chain reaction-based HIV
RNA assay is sufficiently sensitive to evaluate the antiviral effect of
a drug in patients with > 500 CD4 cells/mm3.
