About this study
Official title: Toxicological Screening by GC-MS Among Children Admitted for a First Afebrile Seizure (CASTox): a Pilot Study
Before the age of 14 years, 1% of the paediatric population will develop a seizure. The only systematically required complementary examination is an electroencephalogram (EEG). Additional biological or radiological examinations depend on the circumstances, the past medical history of the patient and other associated symptoms or clinical signs. A seizure can be the first sign of acute intoxication and represents a severity criterion. Failure to detect the toxic cause of a seizure can lead to a delay in the access or administration of an antidote if applicable. This can lead to target organ toxicity due to the absence of specific treatment. In the current French guidelines for a first seizure, a toxicological analysis is recommended if there is a possibility of exposure to toxic medications or products. However, this screening is often missing, unless a witness suggests that the child may have been exposed to a toxin.The recognition of a paediatric toxidrome is low among paediatricians, paediatric neurologists or emergency physicians. This is due to a lack of knowledge in clinical toxicology and the screening for toxic aetiology is not frequently or irrelevantly prescribed. There is an increasing number of proconvulsive molecules on the market. These molecules are not targeted in classic toxic screening. As result, a toxic cause of a seizure may be missed unless specific screening is performed. For all these reasons, little is known about the prevalence of toxic causes after a first episode of non-febrile seizure and probably under estimated in the paediatric population, especially in young children. New technologies for toxic detection like chromatography combined with mass spectrometry allow wide screening on different matrix. Initially dedicated to forensic analysis, they are more widely accessible for the exploration of the patients. The CASTox study is based on this context.
The first aim will be to evaluate the prevalence of a toxicological cause by a systematic blood and urine screening of children admitted to Toulouse paediatric emergency unit for a first afebrile seizure. Moreover, secondary aim will be to describe the effect of the systematic screening on the management of the children.

Before the age of 14 years, 1% of the paediatric population will develop a seizure. The only systematically required complementary examination is an electroencephalogram (EEG). Additional biological or radiological examinations depend on the circumstances, the past medical history of the patient and other associated symptoms or clinical signs. A seizure can be the first sign of acute intoxication and represents a severity criterion. Failure to detect the toxic cause of a seizure can lead to a delay in the access or administration of an antidote if applicable. This can lead to target organ toxicity due to the absence of specific treatment. In the current French guidelines for a first seizure, a toxicological analysis is recommended if there is a possibility of exposure to toxic medications or products. However, this screening is often missing, unless a witness suggests that the child may have been exposed to a toxin.The recognition of a paediatric toxidrome is low among paediatricians, paediatric neurologists or emergency physicians. Since the end of the 90s, the molecules usually incriminated with seizure onset after intoxication are: with a high risk (polycyclic antidepressant, theophylline, isoniazid); intermediate risk (fluoroquinolones, tramadol, lidocaine, lithium, anticonvulsive medications) and low risk (selective serotonin reuptake inhibitors). Among infants, the molecules are quite different mainly because of the unintentional or malicious aspect of the intoxication and are dominated by sympathomimetic agents, antihistamine drugs, anticholinergic molecules, antidepressants and muscle relaxants. New drugs have been associated with seizures in young intoxicated children like bupropion, tramadol and venlafaxine. These agents are not detected by usual toxic analysis.
For each patient and after getting the signed consent form, a toxicological analysis will be performed on blood and urine samples to extensively screen for proconvulsive molecules (alcohols, polycyclic antidepressants, salicylates, anticonvulsive medications (carbamazepine, phenytoin, valproic acid), drugs (cocaine and its metabolites, amphetamines, methamphetamine (ecstasy), cannabis, buprenorphine, methadone, mephedrone, codeine, pholcodine, hydromorphone), benzodiazepines, caffeine, theophylline, lidocaine, isoniazid, mefenamic acid, tramadol, ephedrine).
This analysis will be performed using classic approach (immunoenzymatic detection) and by chromatography (GC) associated to mass spectrometry (MS) (Laboratory of Toxicology, University Hospital of Toulouse) - The other clinical data, biological results or tests requested by the physician in charge will be reported from the computerized medical file of each patient.
For each patient hospitalized, a follow-up visit will be scheduled during hospitalization in order to report management of the children.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Before the age of 14 years, 1% of the paediatric population will develop a seizure. The only systematically required complementary examination is an electroencephalogram (EEG). Additional biological or radiological examinations depend on the circumstances, the past medical history of the patient and other associated symptoms or clinical signs. A seizure can be the first sign of acute intoxication and represents a severity criterion. Failure to detect the toxic cause of a seizure can lead to a delay in the access or administration of an antidote if applicable. This can lead to target organ toxicity due to the absence of specific treatment. In the current French guidelines for a first seizure, a toxicological analysis is recommended if there is a possibility of exposure to toxic medications or products. However, this screening is often missing, unless a witness suggests that the child may have been exposed to a toxin.The recognition of a paediatric toxidrome is low among paediatricians, paediatric neurologists or emergency physicians.

Questions about this trial
What is this clinical trial studying?
A study testing Collection of blood and urine samples and Clinical examination in people with Afebrile Seizure (Finding), run by University Hospital, Toulouse at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Detection of one or several toxic molecules. (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03310697, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2021.
