A quantitative DNA amplification assay for human cytomegalovirus (CMV) DNA
has been used to evaluate the relationship between quantities of CMV DNA in
plasma and those in infected leukocytes (WBC) from human immunodeficiency
virus-infected patients. The target sequence for DNA amplification was a
region of the immediate-early 1 gene of CMV. The quantitation assay uses an
internal control that is coamplified with each patient sample DNA and
contains a sequence for detection by colorimetric hybridization with the
same bases, but in different order than in the CMV immediate-early 1 region
used for hybridization of amplified patient sample DNA. Results showed that
patients with CMV disease had more CMV DNA in both WBC and plasma than
those without disease. However, in this study, copy numbers of CMV DNA in
WBC were higher than those in plasma. The gB and gH variants were the same
in plasma and WBC.
