NYU Langone and SUDCRRC: SUDC with Febrile Seizure History
Raphe and ventrolateral medulla proteomics in sudden unexplained death in childhood with febrile seizure history- Dominique F. Leitner, Christopher William, Arline Faustin, Evgeny Kanshin5 · Matija Snuder, Declan McGuone, Thomas Wisniewski, Beatrix Ueberheide, Laura Gould, Orrin Devinsky.

Researchers at NYU Langone, SUDC Registry and Research Collaborative (SUDCRRC) are improving our understanding of why some seemingly healthy children die suddenly and unexpectedly. Sudden Unexplained Death in Childhood (SUDC) is a category of death in children between the ages of 1 and 18 that remains unexplained after a thorough investigation, including an autopsy.
In a recent study, scientists analyzed brainstem samples from SUDC autopsies to identify proteins expressed differently in children with or without febrile seizures. The brainstem, which regulates vital functions like breathing, was studied due to its potential role in SUDC, and febrile seizures were targeted because they are more common in SUDC cases. Using mass spectrometry, which detects thousands of proteins in a sample, they compared protein levels across three brainstem regions in children with and without febrile seizure histories.
Key findings included proteins with significantly different levels in children with febrile seizures, particularly those with longer seizure histories, some of which are linked to functions potentially related to SUDC. Further analysis using antibody staining provided novel information about localization of these proteins in human tissue.
This research identified significant protein differences that give scientists leads about potential mechanistic, diagnostic biomarker, and therapeutic strategies to study further. This research will help guide future studies to better understand sudden deaths in children and could lead to new ways to reduce risk.

This study, published in Neurology, January 4, 2024, addresses the challenge of understanding sudden unexplained deaths in toddlers, which account for over 2,900 cases annually in the United States. Typically occurring during sleep and going unnoticed with unremarkable autopsies, these deaths pose a significant mystery.
The research focuses on evaluating videos of sudden deaths in toddlers to gain insights into potential mechanisms. The study analyzes seven cases with home video recordings of the child's last sleep period. The findings suggest a strong association between unexplained sudden deaths and convulsive seizures in toddlers. Continuous recordings revealed convulsive events lasting 8–50 seconds, with four children surviving for more than 2.5 minutes post convulsion.
Notably, the study dismisses primary cardiac arrhythmias as a cause, as all seven children had normal cardiac pathology, and genetic testing identified no known cardiac disease variants.

A systematic review of research related to simple febrile seizures and those less than 30 minutes in duration. The study found: "Sudden death registries focused on a tiny minority of febrile seizure cases but support that simple febrile seizures can rarely increase mortality risk. Hippocampal histopathological anomalies are common in children who die suddenly, with or without febrile seizures. When present, neurodevelopmental issues usually precede febrile seizure onset. Long-term population-based prospective studies are needed to better define outcomes in children with febrile seizures." DOI: 10.1111/epi.17720

Proteomic differences in hippocampus and cortex of sudden unexplained death in childhood
Genes determine the structure and the function of proteins and these proteins ultimately result in traits. Proteomics is the study of proteins. This is the first published study of proteomics in SUDC which studied the brain tissue (cortex and hippocampus) from 19 SUDC and 19 control. Molecular signaling pathways associated with protein differences were identified. Some protein changes correlated to SUDC clinical history. Authors identify need for larger scale analyses, mechanistic studies, and proteomic analysis in other brain regions to improve our understanding of SUDC.

Blinded Review of Hippocampal Neuropathology in Sudden Unexplained Death in Childhood Reveals Inconsistent Observations and Similarities to Explained Pediatric Deaths. Neuropathol Appl Neurobiol. 2021 Jun 23. doi: 10.1111/nan.12746. Epub ahead of print. PMID: 34164845.
Researchers at the SUDCRRC utilized hippocampal H&E slides (n=67; 36 SUDC, 31 controls) and evaluated them across 9 blinded reviewers. Results identified a lack of an association of hippocampal findings in SUDC and controls. Inconsistent observations call for larger studies to standardize the evaluation of hippocampal findings and better understand its normal variation.

Forensic pathologists blindly reviewed 100 case series of sudden unexpected pediatric deaths enrolled in the SUDC Registry and Research Collaborative 2014-2017. These reviewers were discordant with the original certifier’s cause of death (COD)opinion in 40% of cases, including 28 cases originally considered accident or natural but adjudicated as unexplained by our review. The blinded comprehensive review and adjudication process of the SUDCRRC suggests the SUDC rate by the U.S. Centers for Death Control and Prevention (CDC) may be an underestimation and that there is a low rate of consistency in death certification of sudden unexpected pediatric deaths.

Authors prospectively performed systematic neuropathologic investigation in 20 SUDC cases and found hippocampal alterations were the most common finding on histological review but were also found in possibly explained deaths. They concluded the “significance and specificity of hippocampal findings is unclear as they may result from seizures, contribute to seizure pathogenesis, or be an unrelated phenomenon”.

A case series study of 622 consecutive sudden child death cases aged 1 to 17 years from 2001 to 2017 from 18 countries reported to the SUDC Foundation. 391 families with child deaths aged 1 to 6 years with completed interviews were analyzed. “This analysis of the largest SUDC cohort confirmed an increased FS rate and found significantly increased rates of FS among sudden explained deaths in children. This study suggests that seizures may contribute to some SUDC and SEDC deaths. The risk of sudden death in a sibling was low. To develop and assess preventive strategies, population-based studies are needed to define the epidemiology and spectrum of risk factors and identify biomarkers of patients with FS at high risk of sudden death.”

Authors surveyed bereavement organization and bereaved parents to understand their perceptions of changing practices in regards to shifts in diagnoses of sudden infant death- including the use of SIDS, undetermined and asphyxia. Over 50% (34/67) of the organizations perceived the changing practices as effecting their ability to provide bereavement support and education. Forty percent (22/55) of parent stated they did not understand the final diagnosis of their infant's death. Author recommendations include the integration of collaborative efforts to combat sudden infant death with all stakeholders, in and outside of MDI, to achieve better understanding and eradication of these tragedies, improved public education, and effective care of all bereaved.

Authors analyzed data of 123 consecutive children with SUDC reported to the SUDC program (4/1/11-3/31/14) by their parents and report that “31.7% of SUDC cases had a history of FS, among which 74.4% had simple FS. Compared to those without a history of FS, a history of FS was associated with a greater median age at death (p = 0.03) and death during the weekdays (p = 0.02). Terminal fever was similar in those with and without FS. The median time from FS to death was 6.0 months (interquartile range [IQR] 3.0-10.0). In all SUDC cases, prone position at death, death during sleep, and unwitnessed deaths predominated. There are parallels among SUDC, sudden infant deaths, and sudden unexpected death in epilepsy (SUDEP) with regard to prone position, unwitnessed deaths mostly during sleep, and male predominance. The greater than expected prevalence of a FS history and the proportion with terminal fever or illness in this cohort suggests that some SUDC deaths may be seizure related and therefore have potential commonalities with SUDEP.”

197 professionals and 156 bereaved parents were surveyed regarding death investigation practices and experiences. Results showed that the majority of professional respondents (96.5%) allow the next of kin (NOK) to view his/her child before transport to the morgue while holding the infant/child was somewhat less commonplace (68.9%). The majority of professional respondents (70.4%) would also permit memorial keepsakes to be made. Furthermore, professional practices and NOK experiences in regard to communicating preliminary and final cause of death information to the NOK were highly variable.

SWGMDI provides the 13 principles for professionals communicating with surviving families members during medicolegal death investigations. The authors explain that “families of individuals who died in situations requiring an investigation experience additional challenges and emotions not faced by families following normal or anticipated deaths. Sudden deaths exacerbate the experience of grief and loss- regardless of the manner of death. How medicolegal professionals communicate with families in the aftermath of a death will have a direct impact on their ability to cope, their view of the medicolegal system, and their willingness to cooperate with the investigation and future proceedings.”

Krous, M.D. Sudden Death, Febrile Seizures, and Hippocampal and Temporal Lobe Maldevelopment in Toddlers: A New Entity Pediatr Dev Pathol 2009 Jul 16:1. DOI: 10.2350/08-09-0542.1
26 SUDC cases with available hippocampal sections, 62% (16/26) had hippocampal and temporal lobe anomalies. Authors conclude potential new entity defined by sleep-related death in prone position, with individual/family history of febrile seizures, and hippocampal and temporal lobe anomalies. This study mandates further research into the potential link between simple febrile seizures and death.
Baker AM, Crandall L. To Hold Or Not To Hold. Forensic Sci Med Pathol. 2009 (Dec; 5(4):321-3.
Dr Baker and Ms Crandall write a commentary discussing the pathologist versus family perspectives in death scene investigations. The authors conclude, “in the majority of situations—and certainly whenever possible—the family should be allowed a reasonable amount of time to touch and hold their child, managed in a way that does not hamper the investigation process.”

Kinney HC, Armstrong DL, Chadwick AE, et al. Sudden Death in Toddlers Associated with Developmental Abnormalities of the Hippocampus: a report of five cases. Pediatr Dev Pathol. 2007;10:208-223 DOI: 10.2350/06-08-0144.1
Case report of 5 cases of SUDC in toddlers that we believe define a new entity associated with hippocampal anomalies at autopsy. Authors suggest risk factors include a case and/or family history of febrile seizures and recommend future studies to confirm and further evaluate findings.
Krous H, Chadwick A, Miller D, Crandall L, Kinney H. Sudden Death in Toddlers with Viral Meningitis, Massive Cerebral Edema, and Neurogenic Pulmonary Edema and Hemorrhage: Report of Two Cases. Pediatr Dev Pathol. 2007;10:463-469 DOI: 10.2350/06-08-0156.1
Case report of 2 sudden deaths in toddlers with clinical evidence of a viral infection and found at autopsy to have lymphocytic meningitis. Viral (lymphocytic) meningitis typically does not cause sudden death. Authors recommend the importance of a comprehensive autopsy, including detailed neuropathologic examination and viral testing, in determining of the cause of unexpected death in toddlers.
Masoumi H, Kinney HC, Chadwick AE, Rubio A, Krous HF. Sudden unexpected death in childhood associated with cardiac rhabdomyoma, involuting adrenal ganglioneuroma, and megalencephaly: another expression of tuberous sclerosis? Pediatr Dev Pathol. 2007;10:129-133. DOI: 10.2350/06-04-0081.1
A case report of a 9-year-old, previously healthy girl who died suddenly and unexpectedly and was found at postmortem examination to have a cardiac rhabdomyoma, megalencephaly, and an involuting adrenal ganglioneuroma. The authors suggest a possible diagnosis of tuberous sclerosis, but confirmatory genetic analysis was not performed.

The first published definition of SUDC describing a profile characterized as male, 1 to 3 years in age, predominantly male, frequently personal and family history of seizures, and being found prone. The authors recommend legislation enabling research and formation of a multicenter research team to unravel the mystery of SUDC.
Wixom C, Krous HF, Chadwick AE. Sudden, Unexpected Death Associated with Meningioangiomatosis. Pediatr Dev Pathol. 2005;8:240-244 DOI: 10.1007/s10024-004-9105-4
A case report of a 13-year-old, previously healthy male without a history of seizures, neurologic deficits, or clinical stigmata of neurofibromatosis or family history. The autopsy revealed a brain mass descriptive of meningioangiomatosis (type of mass in/around meninges). The authors speculate his death was the result of a seizure due to meningioangiomatosis.
