Abstract
- AbstractBackground:Cytomegalovirus (CMV) is known as a common pathogen causing infections after lung transplantation. Rapid diagnosis of CMV infection is important for the initiation of a specific treatment. Objective:Evaluation of methods for the rapid diagnosis of CMV pneumonitis. Methods:The detection rates of CMV DNA in bronchoalveolar lavage (BAL) and bronchial brushes by polymerase chain reaction (PCR), of viral antigens (p52 and IE1) in BAL and of pp65 antigen in peripheral blood leukocytes were compared to the clinical status after lung transplantation. In 28 patients, 105 BAL, 96 blood samples and 14 brushes were analyzed. Results:In 6 patients, a total of eight episodes of CMV pneumonitis occurred. Five of the 6 with positive CMV antigens in BAL (p52 or IE1) showed signs of CMV pneumonitis. All episodes of CMV pneumonitis were detected by the PCR of BAL cells. Fourteen samples positive for CMV pp65 antigen in blood were negative in BAL PCR. In these cases, no clinical signs of pulmonary CMV infection occurred. Overall sensitivity, specificity, and positive and negative predictive values for the detection of CMV pneumonitis by PCR of BAL cells were 100, 98.9, 88.9 and 100%, respectively. In brush samples, PCR did not provide additional information to the results of the PCR of BAL cells. Conclusions:PCR of DNA from BAL cells is suitable for reliable and rapid detection of CMV pneumonitis.Copyright © 2000 S. Karger AG, Basel
