title: Early diagnosis and monitoring of human cytomegalovirus pneumonia in patients with adult T-cell leukemia by DNA amplification in serum.
abstract: A nested polymerase chain reaction (PCR) was used to detect human cytomegalovirus (HCMV) DNA in serum of patients with adult T-cell leukemia (ATL). Serum samples were collected consecutively from 11 patients with HCMV pneumonia diagnosed histopathologically and 7 HCMV-seropositive patients without HCMV disease. Serum samples obtained from 24 HCMV-seropositive healthy volunteers were used as controls. The HCMV DNA was detected in serum a mean of 14 days before the onset of HCMV pneumonia, which suggests that DNAemia exists prior to the development of HCMV pneumonia. The amount of viral DNA in serum increased with disease progression and decreased with disease improvement. Thus, the detection of HCMV DNA in serum by nested PCR is useful for monitoring and the early diagnosis of HCMV pneumonia in patients with ATL. In addition, quantitation of HCMV DNA may be useful for monitoring HCMV infection, because it appears to correlate with the activity of the disease.
