Undetectable plasma HIV-1 RNA with strong gag-pol specific interferon-gamma ELISPOT response in an HIV-1 clade A/E-infected child untreated with antiretroviral therapy.

We report a 7-year HIV-1 clade A/E-infected child untreated with antiretroviral therapy who had positive HIV antibody testing but undetectable plasma HIV-1 RNA by Roche Amplicor version 1.5 and bDNA version 3.0. DNA PCR was positive by methods using gag/pol primers but not env/pol primers. The patient had strong HIV-1-specific cytotoxic T lymphocyte responses, which likely contributed to her low viral burden and undetectable plasma HIV-1 RNA.
