Home-Based Exercise Training in Childhood-Onset Takayasu Arteritis: A Multicenter, Randomized, Controlled Trial

Area of Science:

• Pediatric rheumatology
• Cardiovascular research
• Exercise science

Background:

• Childhood-onset Takayasu Arteritis (c-TA) is a rare, life-threatening vasculitis affecting large arteries in children.
• Limited evidence exists on the benefits of exercise for c-TA patients.
• Understanding exercise's role is crucial for improving patient health outcomes.

Purpose of the Study:

• To investigate the safety and therapeutic potential of a home-based exercise intervention for children with c-TA in remission.
• To assess the effects of exercise on arterial inflammation and systemic inflammatory markers.
• To evaluate secondary outcomes including physical activity, functionality, body composition, and quality of life.

Main Methods:

• A 12-week, multicenter, randomized controlled trial comparing home-based exercise to standard care in c-TA patients.
• Primary outcome measures included arterial inflammation via [18F] FDG-PET/MRI and systemic inflammatory markers.
• Secondary outcomes assessed physical activity, functionality (SF-36), body composition, and disease parameters.

Main Results:

• Exercise did not worsen arterial inflammation; instead, it reduced severe inflammation in vessel segments (P=0.007).
• Exercised patients showed significant improvements in visceral fat, daily steps, and physical functioning (SF-36 physical component) (P ≤ 0.05).
• No adverse events related to exercise were reported.

Conclusions:

• Home-based exercise is a safe and potentially beneficial intervention for children with c-TA.
• Exercise can lead to reduced arterial inflammation and improved physical health markers.
• This study supports exercise as a novel, evidence-based approach to enhance general health in c-TA patients.
