In the present prospective study, five blood tests for detection of
human cytomegalovirus (HCMV), nucleic acid sequence-based amplification
(NASBA) for detection of early (immediate-early antigen) and late
(pp67) mRNA, PCR for detection of HCMV DNA (DNA PCR), culture, and pp65
antigenemia assay, and culture and DNA PCR of urine and throat swab
specimens were compared for their abilities to predict the development
of disease caused by HCMV (HCMV disease). Of 101 human immunodeficiency
virus (HIV)-infected patients with

Value of Different Assays for Detection of Human
Cytomegalovirus (HCMV) in Predicting the Development of HCMV Disease in
Human Immunodeficiency Virus-Infected Patients
100 CD4+ lymphocytes
per mm3, 25 patients developed HCMV disease. The pp65
antigenemia assay (sensitivity, 50%; specificity, 89%) and DNA PCR of
blood (sensitivity, 69%; specificity, 75%) were most accurate in
predicting the development of HCMV disease within the next 12 months.
Both blood culture and late pp67 mRNA NASBA had high specificities (91 and 90%, respectively) but low sensitivities (25 and 13%,
respectively). The sensitivities of urine culture, DNA PCR, throat swab
specimen culture, DNA PCR, and NASBA of blood for detection of the
immediate-early antigen were 73, 87, 53, 67, and 63%, respectively,
and the specificities were 58, 46, 76, 60, and 72%, respectively. The
positive predictive values of all tests however, were low and did not
exceed 50%. In conclusion, virological screening by these qualitative
assays for detection of HCMV is of limited value for prediction of the development of HCMV disease in HIV-infected patients.
