Detection of cytomegalovirus in bronchial lavage and urine using a monoclonal antibody to an HCMV early nuclear protein.
Laboratory diagnosis of 24 cases of human cytomegalovirus (HCMV) infection in patients with the acquired immunodeficiency syndrome, renal transplant recipients and premature infants was achieved. These results were obtained by a rapid, sensitive and versatile HCMV-antigen detection method, which combined cell culture and immunoperoxidase staining with a monoclonal antibody to an HCMV "early" nuclear protein. The results were compared with HCMV isolation by the conventional cell culture method. While some of these immunocompromised patients lacked a significant antibody response, infective HCMV could be detected in the patients' urine and bronchial lavage fluid. The diagnostic procedure took no longer than 24 h. The usefulness of this antigen test for an effective diagnosis in immunocompromised individuals was demonstrated. We recommend routine analysis of various specimens, since recent developments in chemotherapy of HCMV infection and the risks of long-term damage demand immediate management of the patients concerned.
