- Brief Summary
Arterial ischemic stroke (AIS) is a devastating condition, affecting 1.6-5/100,000 children/year. Although their outcome is different, children with stroke do not recover better than adults, with at least 2/3 suffering long term sequels such as developmental (motor, global intellectual, language...) and behavioral disabilities, epilepsy, and low adaptative and academic skills...
Stenotic cerebral arteriopathy is identified as AIS etiology in 60-80% of previously healthy children and the course of this arteriopathy is the strongest predictor of recurrent events. 30-40% of these children have a focal unilateral cerebral arteriopathy (FCA). Childhood FCA is suspected to be an inflammatory vessel wall pathology triggered by varicella and other (viral) infections. As recurrences occur for the great majority in the first 6 months after the index event, aspirin 5 mg/kg/day is recommended for at least 18 months to 2 years.
As there is a rational for using immunomodulatory drugs at the acute stage of FCA, immunotherapies are currently used by neuropaediatricians in AIS, mainly as steroids for children with stenosing arteriopathies. However, due to weak evidences, the literature cannot either encourage or discourage this practice.
The long term course of children with FCA is only approach to date by retrospective studies and controversies about outcome remain (for example, the recurrence risk on antithrombotic treatment varies notably from quasi zero to 25%). And finally, it is shown in childhood stroke, as well as in the global field of longstanding impairment, that parental and medical points of view do not match consistently. Longitudinal studies are needed to deserve this familial approach.

Children with moyamoya or sickle cell disease.
-
Children with a progressive large to medium vessel childhood primary angiitis of the central nervous system with two out of the following three criteria : Children with progressive neurocognitive dysfunction; Children with bilateral lesions/vessel involvement; Children with distal arterial stenosis (beyond the M2, A1 or P2 segment).
- Children already on steroid treatment at disease onset or with a contraindication to receive steroid treatment (e.g. congenital or acquired immunodeficiency).
-
Children with delayed diagnosis ≥3 days as treatment start is not allowed to be more ≥5 day-delayed.

Group Intervention Description experimental group Methylprednisolone + prednisolone Children will be treated by methylprednisolone + prednisolone and standard of care
- Primary Outcome Measures
Name Time Method Time to recovery up to 12 months Up to 12 months Evaluate of time to recovery up to 12 months by score paediatric Recurrence and Recovery Questionnaire (RRQ )
- Secondary Outcome Measures
Name Time Method Improvement of functional outcome by face-to-face visits Months:1,6,12, 24 and 36 Evaluate of Improvement of functional outcome by face-to-face visits by score Paediatric Stroke Outcome Measure (PSOM), modified Rankin Scale (mRS) and Vineland Adaptive Behaviour Scale (VABS).
Recurrence of stroke, epilepsy, neurological and developmental sequels, and academic achievement Months: 1, 3, 6,12, 24 and 36 Evaluate recurrence of stroke, epilepsy, neurological and developmental sequels, and academic achievement at 6, 12, 24 and 36 months. Neurological outcome will be assessed by standard clinical examination: motricity, sensibility, coordination, oculomotricity and visual field, cranial nerves...
Number of serious adverse events Months 72 Analysis of number of serious adverse events and their cause, consequence.
Arteriopathic course along time Months: 1, 6, 24 Evaluate of Arteriopathic course along time by comparison between magnetic resonance (MR) arteriography and initial imaging.
Outcome by age group Months 72 Evaluate outcome by age group. All endpoints will be stratified for the whole cohort by the following age group: 0.5-3 years; 3-6 years; 6-10 years and ≥10 years. This will be done in a centrally-manner at Clinical Trials Unit (CTU) Bern.
Familial impact Months 72 Evaluate of familial impact by Alberta Perinatal Stroke Parental Outcome Measure (APSOM) and indepth interview through semi-structured interviews. The objective is to report the lived experience of parents whose child was included in the study.
