Preemptive therapy is a promising strategy for the prevention of serious
cytomegalovirus (CMV) disease after bone marrow (BM) transplantation but
requires relevant diagnostic tests. We compared the clinical value of a
reverse transcription (RT)-PCR method, which detected a late viral mRNA in
peripheral blood leukocytes (PBL), with a PCR method that detected the
viral DNA in PBL and with viral culture from leukocytes and urine for the
diagnosis of symptomatic CMV infection after BM transplantation. Forty-five
consecutive BM recipients were prospectively tested at weekly intervals by
the four methods. CMV infection, demonstrated either by the culture of CMV
or by repeated detection of viral DNA, was observed in 28 patients, but
only 14 developed CMV-related clinical symptoms. The clinical sensitivity
and specificity of each technique for detection of symptomatic infection
were, respectively, 36 and 74% for urine culture, 43 and 84% for leukocyte
culture, 100 and 65% for PCR, and 71 and 94% for RT-PCR. Although PCR
detection of DNA in PBL was the earliest and most sensitive technique for
the diagnosis of CMV infection, RT-PCR was more predictive of the onset of
CMV-related clinical symptoms. These data suggest that both molecular
methods should be used for identifying BM recipients at highest risk of CMV
disease.
