Application of competitive PCR to cerebrospinal fluid samples from patients with herpes simplex encephalitis.

ABSTRACT: The purpose of the present study was to determine if the quantity of herpes simplex virus (HSV) DNA in the cerebrospinal fluid (CSF) of patients with herpes encephalitis would be useful in establishing the prognosis of the disease and to determine the effect of antiviral therapy on the clearance of viral DNA from the CSF. Quantitation of HSV DNA was done by constructing an internal standard (IS) from the glycoprotein B amplicon which had a 25-bp deletion between primer annealing sites. Each CSF specimen was coamplified with the IS and the ratio of the amount of HSV/amount of IS was compared to the ratios on a standard curve constructed with the same IS plus known amounts of HSV DNA. CSF specimens were available from 16 patients who were treated with intravenous acyclovir, and the amount of
