Abstract:
Biomarkers have emerging roles in diagnosis, prognostication, and treatment monitoring in patients with human immunodeficiency virus-related central nervous system disease. Currently, it is unlikely that a single biomarker will be able to fulfill these roles; rather a combination is more likely. In this review, we use a pathogenetic framework to discuss biomarkers derived from both the blood and cerebrospinal fluid. Emphasis is given to those biomarkers that have a more solid evidence base and those that are easily measurable.
