Abstract

Background: Early diagnosis of herpes simplex virus-1 (HSV-1) meningoencephalitis is very important because antiviral therapy significantly decreases mortality and morbidity. Polymerase chain reaction (PCR) is a reliable method with high sensitivity and specificity in detection of HSV-1. The aim of this study is to determine the prevalence of HSV-1 in patients with diagnosis of meningoencephalitis using real-time PCR. Materials and Methods: The cerebrospinal fluid samples were collected from 126 patients with clinical diagnosis of HSV-1 meningoencephalitis in Alzahra Referral Hospital in Isfahan, Iran. After deoxyribonucleic acid (DNA) extraction, real-time PCR was performed by fluorescence resonance energy transfer assay and participants underwent brain magnetic resonance imaging, as well. Results: Among 126 patients, 68.3 were male and 31.7 were female. The mean age of the participants was 41.96 +/- 22.36 years. Most of the participants were in the age group of 20u29 years. Three patients (2.4) had positive and 123 patients (97.6) had negative HSV-1 DNA test. Among three positive cases, two were in the age group of 20-29 years and one in the age group of >= 80 years. No HSV-2 DNA was detected. Conclusion: According to the estimated prevalence of HSV-1 meningoencephalitis in the current study, it seems that the prevalence of HSV-1 meningoencephalitis is not too high in our community; therefore, initial empiric acyclovir therapy is frequently overused.
