This clinical trial is focused on studying the effects of high-dose steroids in children who have experienced a stroke due to an inflammatory condition called focal cerebral arteriopathy. This condition involves the narrowing of blood vessels in the brain, often triggered by an infection. The study aims to determine if early anti-inflammatory treatment with steroids can improve the condition of the blood vessels and prevent further strokes in affected children.
The medications being tested in this study are methylprednisolone and prednisolone. Methylprednisolone is administered intravenously, meaning it is given directly into a vein, while prednisolone is taken orally, in the form of tablets. These medications are being used in addition to the standard care, which includes treatments to prevent blood clots.
Participants in the study will receive either the steroid treatment or a placebo, alongside their usual care. The study will monitor changes in the severity of the arteriopathy over time, as well as any improvements in neurological function and the recurrence of strokes. The study will last for several months, with follow-up assessments to track the progress and outcomes of the treatment.
