Clinical Information
Infection with cytomegalovirus (CMV) is a significant cause of morbidity and mortality in transplant recipients and other immunocompromised hosts. Specific neurologic syndromes associated with CMV infection include subacute radiculomyelopathy, peripheral neuropathy, and encephalitis.
CMV-associated central nervous system (CNS) disease occurs most commonly in immunocompromised patients. Histologic evidence of CMV infections in autopsy brain tissue was identified in 20% to 40% of AIDS patients. In 2 separate studies, CMV (DNA) was the most common herpesvirus (29/181, 16/49) detected from the cerebrospinal fluid of patients with AIDS.
CNS infections with CMV can also occur in immunocompetent patients. CMV is a leading cause of congenital viral infections worldwide, and laboratory testing by real-time polymerase chain reaction is useful in the diagnosis of neonatal CMV disease.
Reference Values
Negative
Reference values apply to all ages.
Interpretation
Detection of cytomegalovirus (CMV) DNA in a specimen supports the clinical diagnosis of infection due to this virus.
Studies indicate that CMV DNA is not detected by polymerase chain reaction in cerebrospinal fluid from patients without central nervous system disease caused by this virus.
