Impact of Human Enterovirus 71 Genotypes in Meningoencephalitis in Iran.


ABSTRACT: BACKGROUND:Since the importance of poliovirus has diminished, as a result of its elimination in the majority of countries, non-polioviruses are emerging as causative agents of severe central nervous system (CNS) involvement. Outbreaks of enterovirus 71 (EV71)-associated CNS infections have recently been reported in Asia, Australia, and Europe. OBJECTIVES:This is the first study on genotyping of EV71 in children with meningoencephalitis to be carried out in Iran, and it was conducted in order to obtain an improved understanding of the disease burden of this virus, particularly with regard to CNS involvement. PATIENTS AND METHODS:Viral RNA was extracted from 170 cerebrospinal fluid samples obtained from children aged under 8 years with a primary diagnosis of aseptic meningitis. Specific EV71 PCR was conducted to identify the genotype of the detected EV71 viruses. RESULTS:Human enteroviruses (HEVs) were detected in 89 patients (52.3%). EV71 infection was detected in 19 (21.3%) of the 89 EV71-positive patients, and the C genotype was identified in 15 isolates. CONCLUSIONS:The C genotype should be considered as the prevalent EV71 circulating genotype in Iran, particularly in cases of aseptic meningitis.
