Uncommon Pediatric Immune-Mediated Epilepsy: Disease Course, Diagnosis, and Outcome - A Series of Three Cases.
Immune-mediated epilepsy (IME) constitutes a substantial proportion of drug-refractory epilepsies. Rapid diagnosis and prompt immunosuppression are required along with antiseizure medications (ASMs). Here we report three unrelated children who presented with fever, encephalopathy, and refractory epilepsy and subsequently tested positive for rare intraneuronal and surface receptor antibodies, namely, contactin-associated protein like 2 (CASPR2), glutamic acid decarboxylase (GAD65), and paraneoplastic antigen Ma2 (PNMA2). In all of them, brain magnetic resonance imaging (MRI) was noncontributory. Electroencephalography showed nonspecific interictal epileptic discharges. F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) brain scan revealed abnormality in metabolic pattern with hypermetabolism in basal ganglia, thalami, frontotemporal cortices, and cerebellar hemispheres, consistent with autoimmune encephalitis. Immunosuppression was initiated along with ASMs. Complete seizure freedom was achieved in GAD65 antibody IME and >50% seizure reduction in CASPR2 and PNMA2 antibody IME. A variable degree of behavioral problems persisted in all. Early immunosuppression is warranted in IME, but does not universally guarantee a complete response.
期刊介绍:
The journal has a clinical foundation and has been utilized most by clinical neurologists for improving the practice of neurology. While the focus is on neurology in India, the journal publishes manuscripts of high value from all parts of the world. Journal publishes reviews of various types, original articles, short communications, interesting images and case reports. The journal respects the scientific submission of its authors and believes in following an expeditious double-blind peer review process and endeavors to complete the review process within scheduled time frame. A significant effort from the author and the journal perhaps enables to strike an equilibrium to meet the professional expectations of the peers in the world of scientific publication. AIAN believes in safeguarding the privacy rights of human subjects. In order to comply with it, the journal instructs all authors when uploading the manuscript to also add the ethical clearance (human/animals)/ informed consent of subject in the manuscript. This applies to the study/case report that involves animal/human subjects/human specimens e.g. extracted tooth part/soft tissue for biopsy/in vitro analysis.
