Abstract

Abstract : PCDH19 -related epilepsy is a developmental and epileptic encephalopathy typically presenting with epilepsy and varying degrees of intellectual disability. Seizures typically present in clusters of focal or generalized seizures, sometimes in the setting of fever. We present the case of a 7-month-old girl presenting with new-onset refractory status epilepticus that followed routine vaccine administration and ensuing cytokine storm. She was diagnosed with a pathogenic variant in PCDH19 . The patient required 5 antiseizure medications and pentobarbital-induced burst suppression for control of seizures. She was noted to have elevated serum cytokine levels (interleukin [IL]-2, IL-4, IL-10, IL-13, IL-17, IL-1, IL-1β, and IL-8) and CSF cytokine levels (IL-6 and IL-13). Anakinra was initiated and titrated based on serial cytokine levels, with doses ranging from 5 to 20 mg/kg/d resulting in reduction in cytokine levels and seizure reduction. By age 14 months, she was able to be maintained on 3 active antiseizure medications and ketogenic diet for seizure control.
