Insights
Epstein-Barr virus (EBV) can cause serious neurological issues in children, not just during initial infections. Reactivated EBV infections are linked to conditions like "Alice in Wonderland" syndrome and prolonged encephalitis, impacting cognitive function and brain structure.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neurovirology
Background:
- Epstein-Barr virus (EBV) neurological complications are primarily documented during acute primary infections.
- The study aimed to prospectively investigate EBV's role in pediatric neurological disease, encompassing acute, chronic, and reactivated infections.
Observation:
- Active EBV infections were identified in 10 out of 48 pediatric patients over two years.
- Diagnoses included acute primary EBV (cranial neuritis, cerebellitis), chronic active EBV (T/NK cell lymphoma with cranial neuritis), and reactivated EBV infections.
Findings:
- Seven patients had reactivated EBV infections, presenting with "Alice in Wonderland" syndrome, facial nerve palsy, progressive macrocephaly, or prolonged encephalitis.
- Neurological complications included cognitive impairment, epileptic seizures, and hippocampal lesions (atrophy and sclerosis) in severe encephalitis cases.
- Prognosis varied, with a lethal outcome in T/NK cell lymphoma and long-term deficits in encephalitis patients.
Implications:
- Reactivated EBV infections represent a significant cause of neurological complications in children.
- These complications can lead to severe long-term sequelae, including cognitive deficits and epilepsy.
- EBV reactivation may play a role in the pathogenesis of hippocampal damage in pediatric neurological conditions.
Abstract:
Neurological complications of Epstein-Barr virus (EBV) have been reported almost exclusively in the course of acute primary infections. The role of EBV in paediatric neurological disease was investigated prospectively over a 2-year period, searching for acute primary, chronic, and reactivated EBV infections. Active EBV infections were diagnosed in 10/48 patients, including two with acute primary EBV infections (cranial neuritis and cerebellitis), one with chronic active infection (T/NK cell lymphoma with cranial neuritis), and seven with reactivated infections. Among these seven patients, three showed "Alice in Wonderland" syndrome, one facial nerve palsy, one progressive macrocephaly, and two prolonged encephalitic illness. The prognosis was good except for the patient with lethal T/NK cell lymphoma and the two girls with encephalitic illness. Despite steroid treatment, these girls suffered prolonged cognitive impairment and epileptic seizures. Both developed left-sided hippocampal atrophy, and one of them hippocampal sclerosis. Like primary infections, reactivated EBV infections cause neurological complications in a considerable number of paediatric patients, lead to serious long-term complications, and may contribute to the pathogenesis of hippocampal lesions.
