Abstract

With the rapid progress in the development of highly active antiretroviral therapy (HAART), the observed patterns in human immunodeficiency virus (HIV) encephalitis has changed, allowing herpesvirus (HV) infection to be controlled. HAART was first administered to HIV patients in Cuba in 2001. Consequently with the aim of investigate the behavior of the HVs causing neurological disorders in this population in the post-HAART era, the authors perform a clinical evaluation by a multiplex nested polymerase chain reaction (PCR) assay for simultaneous detection of human HVs--herpes simplex virus (HSV), varicella-zoster virus (VZV), cytomegalovirus (CMV), human herpesvirus 6 (HHV-6), and Epstein-Barr virus (EBV). The authors studied 241 samples of cerebrospinal fluid (CSF) received at the Sexually Transmitted Diseases Laboratory between 2001 and 2005 inclusive. Of the 241 CSF studied, 10.4% resulted positive for HV infections. Of these, 92% of patients were acquired immunodeficiency syndrome (AIDS) individuals at the C3 stage. CMV (44%), EBV (28%), and dual-HV (16%) infections were the most important agents identified. The principal clinical manifestations were fever, headache, vomiting, and focal abnormalities; the latter being associated with an increased risk of death. A statistically significant result was observed when central nervous system (CNS) disease evolution was compared between patients who were under HAART against those who were not, before they developed encephalitis. It was therefore concluded that it is more likely that HIV individuals receiving HAART have a better recovery of CNS infections than those who are not receiving it.
