Mj. Blok et al., Early detection of human cytomegalovirus infection after kidney transplantation by nucleic acid sequence-based amplification, TRANSPLANT, 67(9), 1999, pp. 1274-1277
Background. The early detection of human cytomegalovirus infection after or
gan transplantation is a prerequisite for effective antiviral therapy. We e
valuated the diagnostic value of monitoring the viral immediate-early (IE)
1 mRNA expression in blood leukocytes by nucleic acid sequence based amplif
ication (NASBA).
Methods. Nucleic acids were isolated from 489 blood samples collected from
42 kidney transplant recipients and subjected to amplification by IE NASBA.
The IE NASBA results were compared to those from pp67 NASBA, pp65 antigene
mia, cell culture (DEAFF and CPE), and serology.
Results. IE NASBA proved to be the most sensitive assay which detected the
onset of both primary and secondary cytomegalovirus infection significantly
earlier than the other assays.
Conclusions. The early detection of cytomegalovirus infection with IE NASBA
would enable the start of effective antiviral therapy at an early state of
infection to prevent cytomegalovirus disease in patients at risk.
