Selective elevation of monocyte chemotactic protein-1 in the cerebrospinal fluid of AIDS patients with cytomegalovirus encephalitis.

Abstract

The CC chemokine monocyte chemotactic protein-1 (MCP-1) was markedly elevated in the cerebrospinal fluid (CSF) of human immunodeficiency virus (HIV)-infected patients with cytomegalovirus (CMV) encephalitis. The MCP-1 CSF levels in CMV encephalitis were markedly higher than those in the CSF of HIV-infected patients with or without unrelated neurologic diseases, including progressive multifocal leukoencephalopathy, cryptococcal meningitis, toxoplasmic encephalitis, and primary lymphoma. Interleukin-8, RANTES, macrophage inflammatory protein (MIP)-1 alpha, and MIP-1 beta were not substantially increased in the CSF of CMV encephalitis patients. High levels of MCP-1 may underlie monocyte recruitment and tissue damage in CMV encephalitis and may represent a rapid and useful tool in the diagnostic armamentarium for neurologic disorders associated with HIV infection.
