title: CMV DNA in blood and CSF of HIV infected patients.
abstract: Cytomegalovirus (CMV) infection frequently affects the central nervous system in HIV infected patients. Varied clinical manifestations of CMV disease make virological detection of CMV essential for proper diagnosis and treatment. Thus, in patients in different stages of HIV-induced disease, we attempted to detect cell associated and free, non cell associated CMV DNA in cerebrospinal fluid (CSF) and in peripheral blood mononuclear cells (PBMCs). Twenty-six blood samples were collected from 22 patients included in the study. Nine of these blood samples were tested in pair with the concomitant CSF sample for the presence of CMV DNA by a commercial hybridization test. CMV serostatus and avidity of IgG antibodies were detected by a commercial ELISA test. CMV DNA was present in the cells found in CSF in all but one of the AIDS patients, independently of the presence of neurological symptoms, suggesting that it represented a marker of advanced immunodeficiency, rather than of the specific CMV-related disease. Cell-associated CMV DNA in CSF tested positive even in the samples negative for cell-free CMV DNA in the CSF, and with no detectable CMV DNA in the PBMCs of concomitant blood sample. We believe that searching for CMV DNA in different compartments of CSF merits further attention.
