 AB    To determine whether human immunodeficiency virus (HIV) viral load has
       short term stability, eight clinically stable subjects infected with HIV
       and having CD4 counts ranging between 10-600/mm3, had blood samples
       taken at 0800 and 1700 on 3 consecutive days and then weekly at 0800 for
       1 month (8-10 observations/subject). Plasma HIV RNA, peripheral blood
       mononuclear cell (PBMC) proviral DNA, serum p24 antigen levels, and
       mononuclear cell subsets were measured at each time point. Mean plasma
       HIV RNA, PBMC HIV DNA, and p24 antigen [both regular and immune complex
       dissociated (ICD)] levels did not change significantly between mornings
       and afternoons or on successive days or weeks. CD4+, CD8+, and CD56+
       number demonstrated a diurnal variation in those subjects with > 200 CD4
       cells/mm3. We conclude that HIV viral load demonstrates short-term
       stability in clinically stable subjects. This stability has important
       implications for monitoring HIV disease progression or antiretroviral
       therapy.
