Abstract
PURPOSE The aim of this study was to determine the clinical, laboratory, and radiological factors related with posttraumatic epilepsy (PTE). METHODS The study is a multicenter descriptive cross-sectional cohort study. Children who followed up for TBI in the pediatric intensive care unit between 2014 and 2021 were included. Demographic data and clinical and radiological parameters were recorded from electronic case forms. All patients who were in the 6-month posttraumatic period were evaluated by a neurologist for PTE. RESULTS Four hundred seventy-seven patients were included. The median age at the time of trauma was 66 (IQR 27-122) months, and 298 (62.5%) were male. Two hundred eighty (58.7%) patients had multiple traumas. The mortality rate was 11.7%. The mean duration of hospitalization, pediatric intensive care unit hospitalization and mechanical ventilation, Rotterdam score, PRISM III score, and GCS at admission were higher in patients with epilepsy (p < 0.05). The rate of epilepsy was higher in patients with severe TBI, cerebral edema on tomography and clinical findings of increased intracranial pressure, blood transfusion in the intensive care unit, multiple intracranial hemorrhages, and intubated patients (p < 0.05). In logistic regression analysis, the presence of intracranial hemorrhage in more than one compartment of the brain (OR 6.13, 95%CI 3.05-12.33) and the presence of seizures (OR 9.75, 95%CI 4.80-19.83) were independently significant in terms of the development of epilepsy (p < 0.001). CONCLUSIONS In this multicenter cross-sectional study, intracranial hemorrhages in more than one compartment and clinical seizures during intensive care unit admission were found to be independent risk factors for PTE development in pediatric intensive care unit patients with TBI.

Posttraumatic epilepsy in intensive care unit-treated pediatric traumatic brain injury patients. Epilepsia 2020; 61:693-701. [PMID: 32221978 DOI: 10.1111/epi.16483] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 03/02/2020] [Accepted: 03/02/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Posttraumatic epilepsy (PTE) is a well-described complication of traumatic brain injury (TBI). The majority of the available data regarding PTE stem from the adult population. Our aim was to identify the clinical and radiological risk factors associated with PTE in a pediatric TBI population treated in an intensive care unit (ICU). METHODS We used the Finnish Intensive Care Consortium database to identify pediatric (<18 years) TBI patients treated in four academic university hospital ICUs in Finland between 2003 and 2013. Our primary outcome was the development of PTE, defined as the need for oral antiepileptic medication in patients alive at 6 months. We assessed the risk factors associated with PTE using multivariable logistic regression modeling. RESULTS Of the 290 patients included in the study, 59 (20%) developed PTE. Median age was 15 years (interquartile range [IQR] 13-17), and 80% had an admission Glasgow Coma Scale (GCS) score ≤12. Major risk factors for developing PTE were age (adjusted odds ratio [OR] 1.08, 95% confidence interval [CI] 1.00-1.16), obliterated suprasellar cisterns (OR 6.53, 95% CI 1.95-21.81), and an admission GCS score of 9-12 in comparison to a GCS score of 13-15 (OR 2.88, 95% CI 1.24-6.69). SIGNIFICANCE We showed that PTE is a common long-term complication after ICU-treated pediatric TBI. Higher age, moderate injury severity, obliterated suprasellar cisterns, seizures during ICU stay, and surgical treatment are associated with an increased risk of PTE. Further studies are needed to identify strategies to decrease the risk of PTE.

J Neurosurg Pediatr 2018; 22:684-693.

Abstract
OBJECTIVEPosttraumatic seizures (PTSs) are the most common complication following a traumatic brain injury (TBI) and may lead to posttraumatic epilepsy. PTS is well described in the adult literature but has not been studied extensively in children. Here, the authors utilized the largest nationwide registry of pediatric hospitalizations to report the national incidence, risk factors, and outcomes associated with PTS in pediatric TBI.METHODSThe authors queried the Kids' Inpatient Database (KID) using ICD-9-CM codes to identify all patients (age < 21 years) who had a primary diagnosis of TBI (850.xx-854.xx) and a secondary diagnosis of PTS (780.33, 780.39). Parameters of interest included patient demographics, preexisting comorbidities, hospital characteristics, nature of injury (open/closed), injury type (concussion, laceration/contusion, subarachnoid hemorrhage, subdural hematoma, or epidural hematoma), loss of consciousness (LOC), surgical management (Clinical Classification Software code 1 or 2), discharge disposition, in-hospital complications, and in-hospital mortality. The authors utilized the IBM SPSS statistical package (version 24) for univariate comparisons, as well as the identification of independent risk factors for PTS in multivariable analysis (alpha set at < 0.05).RESULTSThe rate of PTS was 6.9% among 124,444 unique patients hospitalized for TBI. The utilization rate of continuous electroencephalography (cEEG) was 0.3% and increased between 2003 (0.1%) and 2012 (0.7%). The most common etiologies of TBI were motor vehicle accident (n = 50,615), accidental fall (n = 30,847), and blunt trauma (n = 13,831). However, the groups with the highest rate of PTS were shaken infant syndrome (41.4%), accidental falls (8.1%), and cycling accidents (7.4%). In multivariable analysis, risk factors for PTS included age 0-5 years (compared with 6-10, 11-15, and 16-20 years), African American race (OR 1.4), ≥ 3 preexisting comorbidities (OR 4.0), shaken infant syndrome (OR 4.4), subdural hematoma (OR 1.6), closed-type injury (OR 2.3), brief LOC (OR 1.4), moderate LOC (OR 1.5), and prolonged LOC with baseline return (OR 1.8). Surgically managed patients were more likely to experience PTS (OR 1.5) unless they were treated within 24 hours of admission (OR 0.8). PTS was associated with an increased likelihood of in-hospital complications (OR 1.7) and adverse (nonroutine) discharge disposition (OR 1.2), but not in-hospital mortality (OR 0.5). The overall utilization rate of cEEG was 1.3% in PTS patients compared with 0.2% in patients without PTS. Continuous EEG monitoring was associated with higher rates of diagnosed PTS (35.4% vs 6.8%; OR 4.9, p < 0.001).CONCLUSIONSPTS is common in children with TBI and is associated with adverse outcomes. Independent risk factors for PTS include younger age (< 5 years), African American race, increased preexisting comorbidity, prolonged LOC, and injury pattern involving cortical exposure to blood products. However, patients who undergo urgent surgical evacuation are less likely to develop PTS.

NKCC1 up-regulation contributes to early post-traumatic seizures and increased post-traumatic seizure susceptibility. Brain Struct Funct 2016; 222:1543-1556.

Abstract
Traumatic brain injury (TBI) is not only a leading cause for morbidity and mortality in young adults (Bruns and Hauser, Epilepsia 44(Suppl 10):210, 2003), but also a leading cause of seizures. Understanding the seizure-inducing mechanisms of TBI is of the utmost importance, because these seizures are often resistant to traditional first- and second-line anti-seizure treatments. The early post-traumatic seizures, in turn, are a contributing factor to ongoing neuropathology, and it is critically important to control these seizures. Many of the available anti-seizure drugs target gamma-aminobutyric acid (GABAA) receptors. The inhibitory activity of GABAA receptor activation depends on low intracellular Cl−, which is achieved by the opposing regulation of Na+–K+–Cl− cotransporter 1 (NKCC1) and K+–Cl−–cotransporter 2 (KCC2). Up-regulation of NKCC1 in neurons has been shown to be involved in neonatal seizures and in ammonia toxicity-induced seizures. Here, we report that TBI-induced up-regulation of NKCC1 and increased intracellular Cl− concentration. Genetic deletion of NKCC1 or pharmacological inhibition of NKCC1 with bumetanide suppresses TBI-induced seizures. TGFβ expression was also increased after TBI and competitive antagonism of TGFβ reduced NKKC1 expression, ameliorated reactive astrocytosis, and inhibited seizures. Thus, TGFβ might be an important pathway involved in NKCC1 up-regulation after TBI. Our findings identify neuronal up-regulation of NKCC1 and its mediation by TGFβ, as a potential and important mechanism in the early post-traumatic seizures, and demonstrate the therapeutic potential of blocking this pathway.
