Transcriptomic alterations in cortical astrocytes following the development of post-traumatic epilepsy.

ABSTRACT: Post-traumatic epilepsy (PTE) stands as one of the numerous debilitating consequences that follow traumatic brain injury (TBI). Despite its impact on many individuals, the current landscape offers only a limited array of reliable treatment options, and our understanding of the underlying mechanisms and susceptibility factors remains incomplete. Among the potential contributors to epileptogenesis, astrocytes, a type of glial cell, have garnered substantial attention as they are believed to promote hyperexcitability and the development of seizures in the brain following TBI. The current study evaluated the transcriptomic changes in cortical astrocytes derived from animals that developed seizures as a result of severe focal TBI. Using RNA-Seq and ingenuity pathway analysis (IPA), we unveil a distinct gene expression profile in astrocytes, including alterations in genes supporting inflammation, early response modifiers, and neuropeptide-amidating enzymes. The findings underscore the complex molecular dynamics in astrocytes during PTE development, offering insights into therapeutic targets and avenues for further exploration.

Project description:IntroductionPost-traumatic epilepsy (PTE) is a recognised complication of traumatic brain injury (TBI), and is associated with higher rates of mortality and morbidity when compared with patients with TBI who do not develop PTE. The majority of the literature on PTE has focused on adult populations, and consequently there is a paucity of information regarding paediatric cohorts. Additionally, there is considerable heterogeneity surrounding the reported incidence of PTE following childhood TBI in the current literature. The primary aim of our study is to summarise reported PTE incidences in paediatric populations to derive an accurate estimate of the global incidence of PTE following childhood TBI. Our secondary aim is to explore risk factors that increase the likelihood of developing PTE.Methods and analysisA systematic literature search of Embase (1947-2021), PubMed (1996-2021) and Web of Science (1900-2021) will be conducted. Publications in English that report the incidence of PTE in populations under 18 years of age will be included. Publications that evaluate fewer than 10 patients, report an alternative cause of epilepsy, or in which a paediatric cohort is not discernable, will be excluded. Independent investigators will identify the relevant publications, and discrepancies will be adjudicated by a third independent investigator. Data extracted will include incidence of PTE, time intervals between TBI and PTE, seizure characteristics, injury characteristics, patient demographics and clinical data. Data extraction will be performed by two independent investigators and cross-checked by a third investigator. A descriptive analysis of PTE incidence will be conducted and a weighted mean will be calculated. If sufficient data are available, stratified meta-analysis of subgroups will also be conducted.Ethics and disseminationEthics approval was not required for this study. We intend to publish our findings in a high-quality peer-reviewed journal on completion.Prospero registration numberCRD42021245802.

Project description:BackgroundKidney transplantation (KT) is a life-saving therapy for kidney failure. However, KT recipients can suffer from debilitating depression, post-traumatic stress disorder (PTSD), and suicide. In contrast to PTSD, post-traumatic growth (PTG) is a positive psychologic change in response to a challenging situation. PTG has been studied in other chronic diseases, but less is known about its role in the setting of KT. We sought to elucidate the prevalence, predictors, and the effect of PTSD and PTG on post-KT outcomes. We also considered the roles of benefit finding and resilience.MethodsIn a literature review, we identified publications that examined PTSD, PTG, benefit finding, and/or resilience in KT recipients. We excluded case reports and first-person narratives. Publications meeting the specified criteria after full text review underwent data abstraction and descriptive analysis.ResultsOf the 1013 unique citations identified, 39 publications met our criteria. PTSD was the most common construct evaluated (16 publications). Resilience was studied in 11 publications, PTG in nine, and benefit finding in five. Up to 21% of adult and 42% of pediatric KT recipients may experience PTSD, which is associated with lower quality of life (QOL), impaired sleep, and other psychiatric comorbidity. PTG was associated with improved QOL, kidney function, and reduced risk of organ rejection. Although benefit finding tended to increase post KT, resilience remained stable post KT. Like PTG, resilience was associated with lower psychologic distress and increased treatment adherence and confidence in the health care team.ConclusionsPTG, resilience, and benefit finding appear to reduce the risk of PTSD, promote well-being, and reduce risk of graft failure in KT recipients. Future research to understand these relationships better will allow clinicians and researchers to develop interventions to promote PTG, resilience, and benefit finding, and potentially improve post-transplant outcomes such as adherence and reducing risk of organ rejection.
