AbstractObjective: To review pathogens, morbidity and mortality in pediatric intensive care unit (PICU) patients with viral and infectious encephalitis. Methods: Retrospective chart review of all patients with encephalitis admitted to the PICU between 2002 and 2014 was done. Results: Encephalitis (n = 46) accounted for 2.7 % of PICU admissions, but 11.8 % PICU mortality over a 12-y period. A microorganism (primarily virus) was identified in 59 % of encephalitis patients in the PICU. Enteroviruses and herpes viruses were isolated from the cerebrospinal fluid (CSF). Respiratory viruses [such as respiratory syncytial virus (RSV) and influenza viruses] and enteric viruses (such as rotavirus and norovirus) were obtained in the nasopharyngeal aspirate and stool respectively, but undetectable from the CSF. More than one-fourth patients with encephalitis died in the PICU. Boys accounted for 85 % of nonsurvivors and 52 % survivors (p = 0.038). Mechanical ventilation, inotrope, intravenous immunoglobulin (IVIG) and corticosteroid usage were significantly higher among non-survivors (p 0.001–0.044). Binomial logistic regression showed that patients who received corticosteroid had a lower chance of survival than those who did not after adjusting for gender, IVIG and mechanical ventilation (adjusted odd ratio = 0.071, 95 % CI 0.006-0.881; p 0.039). Eighteen (55 %) of the survivors had moderate-to-severe neurodevelopmental impairments. Conclusions: Encephalitis is associated with significant mortality despite intensive care. Over 25 % case died and 55 % of survivors had moderate-to-severe neurodevelopmental impairments. There appeared to be no emerging outbreaks of encephalitis during the 15-y study period.
