 AB    The dynamics of HIV infection early in perinatally infected infants is
       poorly understood. Serial plasma and mononuclear cell (MNC) samples from
       8 HIV-infected infants were assayed by quantitative RNA PCR for free
       virus and by quantitative DNA PCR for infected cells. Virus was
       detectable by RNA PCR in 6/8 infants in the first 11 days of life, with
       a mean among positives of 9.9 +/- 8.7 x 10(5) viral particles/ml plasma.
       For 5 of the 6 newborns, quantities of virus were very high (> or = 2.5
       x 10(5)). Similarly, the HIV provirus was detected in 4/7 MNC samples
       with a mean among positives of 89 copies per 1 x 10(5) MNCs assayed
       (range, 53 to 115). Serial studies over a 3-12 month period revealed a
       persistent high viral load in 6 of 8 infants studied, with 9.3 +/- 8.7 x
       10(5) virus particles per ml plasma (n = 28) and 215 +/- 313 HIV copies
       per 1 x 10(5) MNCs (n = 29). All but one infant had age-appropriate CD4
       lymphocyte counts through 4 months of age and 5/8 through 6 months.
       Similarly, 50% had no HIV-associated signs or symptoms until 6 months of
       age, while those with early symptoms exhibited only organomegaly or
       lymphadenopathy. In conclusion, high viral loads were detected early in
       perinatal infection and usually persisted for months, even in
       conjunction with normal immune cell numbers and clinical course. As
       opposed to adults, persistence of substantial viremia levels suggests an
       ineffective immune response and the need to evaluate early
       antiretroviral therapy in perinatal HIV infection.
