HIV-1-infected patients with a CD4+ lymphocyte count > or = 500 x 10(6)/l may be selected for antiretroviral treatment when viral load is above a given cut-off point. ⋯ A single-point viral load assessment is enough in asymptomatic patients with CD4+ lymphocytes counts > or = 500 x 10(6)/l since plasma HIV RNA measurements obtained 1 month apart are fairly stable. Approximately 25% of these patients (including some patients with LTNP criteria) will be selected for treatment if 30,000 RNA copies/ml is used as cut-off point, and approximately 50% if the cut-off point is 10,000 RNA copies/ml. Viral load > or = 10,000 is very unusual in patients with CD4+ T-cell counts > 750 x 10(6)/l.
