Abstract
Anti-N-methyl-d-aspartate receptor autoimmune encephalitis (NMDAR AE) is an antibody-mediated neurological disorder that may be caused by post-herpes simplex virus-1 meningoencephalitis (HSV ME) and ovarian teratomas, although most pediatric cases are idiopathic. We sought to evaluate if other infections precede NMDAR AE by conducting a single-center, retrospective, case-control study of 86 pediatric cases presenting to Texas Children's Hospital between 2006 and 2022. HSV ME (HSV-1 and HSV-2) was a significantly more common preceding infection in the experimental group compared to control patients with idiopathic intracranial hypertension, while there was no difference in remote HSV infection between the two groups. Recent Epstein-Barr virus infection was evident in 8/42 (19%) tested experimental patients in comparison to 1/25 (4%) tested control patients which provided evidence for a genuine measure of effect but was not statistically significant due to small sample size (p = 0.07). The other 25 infectious etiologies were not different among the two groups and not all variables were clinically indicated or obtained in every subject, highlighting the need for future standardized, multi-institutional studies on underlying infectious precursors of autoimmune encephalitis.
