AB The use of reverse transcription and the polymerase chain reaction
(RT-PCR) has become an integral part of the detection of viral RNA
levels in the plasma of HIV infected individuals. The high sensitivity
of this detection system makes it particularly useful in the monitoring
of anti-retroviral therapy. Previous studies comparing RT-PCR and
quantitative microculture, on a range of patient samples, has shown that
levels detected by RT-PCR exceed infectious virus titre by as much as
1,000-10,000 fold. We have developed and are currently, optimising an
RT-PCR assay that uses CD4 capture to selectively bind intact virions.
Only RNA from these captured particles is subjected to RT-PCR, and
quantified using biotinylated oligonucleotides in a two-stage nested
PCR. The Captagene ELISA from AMRAD Corporation is used to detect the
amplified sequences containing the biotin molecule. We are currently
comparing viral titres from a wide range of patient samples, as measured
with CD4 capture RT-PCR, RT-PCR on total extracted RNA, and quantitative
microculture.
