Abstract:
:Detection of human cytomegalovirus (CMV) DNA in clinical specimens is considered a cornerstone in the diagnosis of CMV disease. The aim of this study was to evaluate a newly designed LightCycler-based quantitative CMV PCR. Specimens of human origin (n = 200) were tested using the LightCycler PCR, the quantitative COBAS AMPLICOR CMV MONITOR (CACM) assay, and a qualitative in-house PCR assay for the presence of CMV DNA. Samples that were reactive in at least two of the three assays were considered CMV DNA positive (n = 95 [47. 5%]), while samples that were nonreactive in two of the three assays were considered CMV DNA negative (n = 105 [52.5%]). Using the LightCycler assay, CMV DNA was detected in 91 of the 95 CMV DNA-positive human specimens (sensitivity, 95.8%; 95% confidence interval [CI], 89.6 to 98.8) and in 1 of the CMV DNA-negative specimens (specificity, 99%; 95% CI, 94.8 to 99.8). Results of CMV load determination as assessed by both quantitative test systems were correlated (r = 0.73; P < 0.0001; 95% CI, 0.61 to 0.81). Results for undiluted samples containing a high CMV load were more accurate with the LightCycler test than were results obtained with the CACM test, which underestimated the viral load of samples containing high DNA copy numbers. The high level of sensitivity, specificity, accuracy, and rapidity provided by the LightCycler technology are favorable for the use of this system in the detection of CMV DNA in clinical specimens.
