Fulminant coronavirus disease 2019 meningitis in Iranian infants: a case series.

Background: Pediatric coronavirus disease 2019 infection usually presents with respiratory and gastrointestinal symptoms. In this report we present fulminant meningitis as the main presentation of coronavirus disease 2019 without major signs and symptoms of other organs' involvement in 3 infants.

Cases: The first case was a 4 months Iranian male infant with fulminant meningitis as the main presentation of coronavirus disease 2019 without other organ involvement. He was treated as suspected bacterial meningitis but CSF PCR and CSF culture were negative for common meningeal pathogens. On 3rd day, his coronavirus disease 2019 PCR test became positive, while it was negative on 1st day. The second case was a 13 months Iranian male infant with fever, irritability, and photophobia for 24 h before poorly controlled status epilepticus. CSF coronavirus disease 2019 PCR became positive while CSF PCR and CSF culture were negative for other common meningeal pathogens. Seizures were controlled with multiple anti-seizure medications. The third case was a 14 months Iranian female infant with fever and seizure1 hour before admission, leading to poorly controlled status epilepticus despite anti-epileptic therapy 10 h after admission. CSF coronavirus disease 2019 PCR became positive while CSF PCR and CSF culture were negative for other common meningeal pathogens. He was controlled with multiple anti-seizure medications.

Conclusion: Meningitis of coronavirus disease 2019 should be considered in severely ill pediatric cases with poorly controlled seizures and RBC in CSF smear. Also, pediatricians can consider corticosteroids, remdesivir, and IVIG therapy in these cases.
