Abstract
- ABSTRACTThe dynamics of active human cytomegalovirus (HCMV) infection was monitored by competitive nucleic acid sequence-based amplification (NASBA) assays for quantification of IE1 (UL123) and pp67 (UL65) mRNA expression levels in the blood of patients after lung transplantation. RNA was isolated from 339 samples of 13 lung transplant recipients and analyzed by the quantitative IE1 and pp67 NASBA in parallel with pp65 antigenemia and serology. Rapid increases in IE1 RNA exceeding 104copies per 100 µl of blood were associated with active infection, whereas lower levels were suggestive for abortive, subclinical viral activity. Any positive value for pp67 RNA was indicative for active infection, and quantification of pp67 mRNA did not give additional diagnostic information. The onset of IE1-positive NASBA preceded pp67 NASBA and was earlier than the pp65 antigenemia assay, confirming previous studies with qualitative NASBA. Effective antiviral treatment was reflected by a rapid disappearance of pp67 mRNA, whereas IE1 mRNA remained detectable for longer periods. Quantification of IE1 might be relevant to monitor progression of HCMV infection but should be validated in prospective studies.
