AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children who recently had a stroke caused by an inflamed blood vessel on one side of the brain (focal cerebral arteriopathy). It tests high dose steroids added to standard care with aspirin.

Age
Older than 6 months and younger than 18 years at the time of the stroke.
Sex
Boys and girls can join.
Disease stage
Newly acquired neurologic deficits, with narrowing or irregular blood vessels on one side only in the brain, seen on MRA imaging. Randomisation within 48 hours of diagnosis and at most 96 hours after stroke onset.
Earlier treatment
Children already on steroid treatment when the disease started cannot join.

Main reasons for not taking part

  • A previous stroke
  • Known syndromes or genetic vessel diseases, such as Trisomy 21 or Neurofibromatosis type 1
  • Moyamoya or sickle cell disease, or vessel disease on both sides
  • Contraindication to steroid treatment, such as an immunodeficiency
  • Taking part in another interventional study in the 30 days before the stroke

High Dose Steroids in Children With Stroke and Unilateral Focal Arteriopathy: A Multicentre Randomized Controlled Trial PASTA (Paediatric Arteriopathy Steroid Aspirin) Trial

This clinical trial deals with focal cerebral arteriopathy and childhood stroke, a rare but devastating condition.

Focal cerebral arteriopathy (FCA) is an inflammatory vessel wall disease provoked by infection and there is increasing evidence that inflammatory processes play a crucial role in childhood stroke, influencing the outcome of the disease.

Analysis of existing data suggests that outcomes are improved and that there is less stroke recurrence in children treated with steroids to reduce the acute inflammatory processes. This clinical trial will be conducted in over 20 hospitals in several countries in order to investigate this.

Participants will be randomly separated into two groups. The first group will be treated with standard of care (including aspirin) combined with high dose steroids. The second group will be treated with standard of care (including aspirin) but without steroid treatment.

The objective is to investigate if children treated with a combination of high dose steroid and aspirin will have a better and quicker recovery of FCA, better clinical functional outcome, and less recurrence compared to children treated with aspirin alone.

This project has been identified by international pediatric stroke experts as the most important topic for a clinical trial in the field and is as well one of the most important research priorities identified by parents. The study results will also provide insight into the evolution of inflammatory vessel disease.
