Acute polyneuritis, a neurological syndrome, can affect children.
Infectious mononucleosis is caused by the Epstein-Barr virus (EBV).
Cytomegalovirus (CMV) is a common virus that can cause various symptoms.
Observation:
A 4-year-old boy experienced recurrent acute polyneuritis.
His sister had infectious mononucleosis with positive Monospot tests.
The boy showed elevated antibodies for EBV and persistent CMV antibodies in serum and CSF.
Findings:
The patient presented with recurrent symmetrical neuropathy.
Elevated Epstein-Barr virus-viral capsid antibody (EBV-VCA) titers were observed.
Persistent cytomegalovirus (CMV) complement fixation antibodies were detected in serum and cerebrospinal fluid (CSF), with oligoclonal bands present in CSF.
Implications:
This case suggests a potential link between CMV infection and recurrent polyneuritis in children.
Epstein-Barr virus reactivation may trigger latent CMV, leading to neurological relapse.
Further research is needed to confirm the causal relationship between CMV and recurrent polyneuritis.
