Aim: The aim of this study was to describe the characteristics of Posterior Reversible Encephalopathy Syndrome (PRES) in infants and young children (<6 years) and to compare them with the older pediatric population affected by PRES. Methods: we retrospectively reviewed records of 111 children (0–17 years) diagnosed with PRES from 2000 to 2018 in 6 referral pediatric hospitals in Italy. The clinical, radiological and EEG features, as well as intensive care unit (ICU) admission rate and outcome of children aged <6 years were compared to those of older children (6–17 years). Factors associated with ICU admission in the whole pediatric cohort with PRES were also evaluated. Results: Twenty-nine patients younger than 6 years (26%) were enrolled with a median age at onset of PRES of 4 years (range: 6 months–5 years). Epileptic seizures were the most frequent presentation at the disease onset (27/29 patients). Status epilepticus (SE) was observed in 21/29 patients: in detail, 11 developed convulsive SE and 10 presented nonconvulsive SE (NCSE). SE was more frequent in children <6 years compared with older children (72% vs 45%) as well as NCSE (35% vs 10%). Seventeen children aged <6 years required ICU admission. Prevalence of ICU admissions was higher within younger population compared to older (59% vs 37%). In the whole study population SE was significantly associated with ICU admission (p = 0.001). Conclusions: PRES in children < 6 years differs from older children in clinical presentation suggesting a more severe presentation at younger age.

Abstract

Aim: The aim of this study was to describe the characteristics of Posterior Reversible Encephalopathy Syndrome (PRES) in infants and young children (<6 years) and to compare them with the older pediatric population affected by PRES. Methods: we retrospectively reviewed records of 111 children (0–17 years) diagnosed with PRES from 2000 to 2018 in 6 referral pediatric hospitals in Italy. The clinical, radiological and EEG features, as well as intensive care unit (ICU) admission rate and outcome of children aged <6 years were compared to those of older children (6–17 years). Factors associated with ICU admission in the whole pediatric cohort with PRES were also evaluated. Results: Twenty-nine patients younger than 6 years (26%) were enrolled with a median age at onset of PRES of 4 years (range: 6 months–5 years). Epileptic seizures were the most frequent presentation at the disease onset (27/29 patients). Status epilepticus (SE) was observed in 21/29 patients: in detail, 11 developed convulsive SE and 10 presented nonconvulsive SE (NCSE). SE was more frequent in children <6 years compared with older children (72% vs 45%) as well as NCSE (35% vs 10%). Seventeen children aged <6 years required ICU admission. Prevalence of ICU admissions was higher within younger population compared to older (59% vs 37%). In the whole study population SE was significantly associated with ICU admission (p = 0.001). Conclusions: PRES in children < 6 years differs from older children in clinical presentation suggesting a more severe presentation at younger age.
