AB Reverse transcriptase (RT) inhibiting antibody in a series of plasma of
HIV-1-seropositive subjects was quantitatively measured by poly A-linked
colorimetric microtiter plate assay. The plasma were obtained from 6
asymptomatic carrier (AC)s and from 3 patients who progressed to AIDS.
They had been followed 29-51 months. RT inhibiting antibody levels in
the plasma were measured by inhibition assay against HTLV-IIIB RT
activity. In five of the 6 AC cases, RT inhibiting antibodies in the
serial plasma maintained high levels, and 50% inhibiting titers of the
serial plasma did not decrease throughout the observation periods (45-51
months). HIV isolation from peripheral blood mononuclear cell (PBMC) of
these 5 ACs did not succeed, and HIV p24 antigens were not detected in
the plasma. In one AC case (046) RT inhibiting antibody levels gradually
decreased after 48 months. In this case, HIV p24 antigen was not
detected in the serial plasma throughout the observation period (48
months), but HIV was isolated from PBMC after 27 months. On the other
hand, RT inhibiting antibody levels in the serial plasma of all 3
patients who progressed to AIDS gradually decreased in observation
periods (29-35 months). HIV strains were isolated from these 3 cases.
These results suggest that reduction of RT inhibiting antibody levels
correlate well with the success of HIV isolation and with progression of
clinical manifestation.
