title: [Clinical evaluation of PCR method for detection of cytomegalovirus DNA].
abstract: Polymerase chain reaction (PCR) to detect Cytomegalovirus (CMV)-DNA from the clinical specimens is useful to diagnose CMV infection. Eighty-one specimens of 31 patients including peripheral blood, bronchioalveolar lavage fluid, biopsy tissues, feces, urine, sputum and etc. and normal peripheral blood from 59 volunteers were used in this study. After DNA extraction each samples was amplified by the seminested PCR using primers recognizing sequences in the Immediate-early gene of CMV. This PCR method specifically detected more than 10 virus copies even in the presence of the genomic DNA. CMV-DNA was detected in only one of 59 normal peripheral bloods (1.7%). Six of 31 patients were clinically diagnosed as CMV infection by anti-CMV therapy. These 6 patients were positive in the peripheral blood by PCR for CMV, and 5 of them were positive in other samples. However, 3, 5 and 1 of 25 patients, who were clinically diagnosed as not having CMV infection, were also positive in peripheral blood, in the other samples and in both, respectively. The PCR method was able to examine any clinical samples. To examine both the peripheral blood and the samples from infected organs is helpful for the diagnosis of CMV infection.
