Abstract

OBJECTIVE: To define the presentation, spectrum of illness, and outcomes in infants with parechovirus (PeV) meningitis admitted to our inpatient general pediatrics service during a spike in incidence of admissions in summer 2022.

PATIENTS AND METHODS: This study is a retrospective case series of all patients aged 3 months and younger discharged from our institution with a CSF BioFire (BioFire Diagnostics, Salt Lake City, UT) FilmArray Polymerase Chain Reaction Meningitis/Encephalitis Panel result positive for PeV between January 1 and September 19, 2022. We collected and analyzed clinical and demographic data.

RESULTS: Eighteen infants with PeV meningitis were admitted within our time frame, with 8 (44%) of the admissions occurring in July. Patients' mean age was 28.7 days and mean length of stay was 50.5 hours. Although all had a history of fever, only 72% were febrile on presentation. Laboratory findings showed a procalcitonin of less than 0.5 ng/mL in 86% of the 14 patients who had it drawn and no cerebrospinal fluid (CSF) pleocytosis in 83% of the patients who had CSF cell counts sent. Neutropenia was present in 17%. Although 89% of infants were given initial antibiotics, antibiotics were discontinued in 63% once their CSF panel returned positive for PeV, and in all by 48 hours.

CONCLUSIONS: Infants hospitalized with PeV meningitis were febrile and fussy, but experienced uncomplicated hospital stays without neurological deficits. Parechovirus meningitis must be considered as a common cause of acute viral meningitis in young infants even without CSF pleocytosis. This study, although limited in scope and follow-up, can potentially assist in the diagnosis and treatment of PeV meningitis at other institutions.
