Evaluating the Role of Inflammation in Neonatal Epileptogenesis

描述
Seizures are a common symptom of neurologic dysfunction in the neonatal period, affecting more than 16,000 newborns in the United States per year. Over 25% of neonates with acute symptomatic seizures develop post- neonatal epilepsy (PNE), which is often resistant to medical therapies. There is a critical need to identify those patients most at risk for PNE and understand the mechanisms by which early seizures increase the propensity for recurrent seizures, in hopes of identifying novel therapeutic targets in this population. There is increasing evidence for the role of neuro-inflammation in the development of epilepsy. Levels of cytokines and micro-RNA (miRNA) may serve as markers of disease severity and have been implicated in epileptogenesis in animal models. The purpose of this study is to evaluate plasma cytokine and miRNA levels after neonatal-onset acute symptomatic seizures and determine their association with acute seizure severity and PNE.

|---|---|
| Acute symptomatic seizures This is a cohort of 72 participants who will be enrolled into this study from the neonatal intensive care unit (NICU) after being diagnosed with seizures. They will be asked to contribute a blood specimen obtained within 24-72 hours after seizures are diagnosed, to participate in an optional blood draw at 2-4 months of age, and to complete surveys at 12 & 24 months of age. | Other: Acute symptomatic seizures Regarding epilepsy and development. |
| Control This is a cohort of 15 participants who will be enrolled into this study from the neonatal intensive care unit (NICU) after having an EEG for possible seizures, but found to have a normal EEG. They will be asked to contribute a blood specimen obtained within 24-96 hours after birth. |
