Abstract:
Increased postcontrast enhancement in contrast-enhanced magnetic resonance imaging (CE-MRI) of the central nervous system (CNS) is a predictor of human immunodeficiency virus (HIV) dementia severity in HIV-infected subjects. The present study confirms this earlier finding in a mildly impaired patient cohort, and demonstrates that the increased postcontrast enhancement is correlated with increased cerebrospinal fluid (CSF) levels of monocyte chemoattractant protein (MCP)-1, an inflammatory chemokine, and increased CNS levels of mI, a microglial marker. These results suggest that early CNS inflammation may underlie the microvascular changes observed, and may be a factor in the development of HIV dementia.
