Exercise, Creatine and Coenzyme Q10 for Childhood Myositis
Sponsor: The Hospital for Sick Children
Summary
Children with Juvenile Idiopathic Inflammatory Myopathies (JIIM) are weak and get tired because their muscles aren't able to work like healthy muscles. This can make it hard for them to do normal everyday things and can make them less happy about their lives compared to children without the disease. There are two nutritional supplements that help muscles use energy and recover after exercise: creatine and coenzyme Q10. If the muscle has more energy, it may not be as weak and may not feel as tired or sore after exercise. Because of this we want to see if having children with JIIM take creatine and coenzyme Q10 can make them stronger and less tired. If this works, we hope it will let them be able to do the things that healthy children can do, and make them feel better about their lives.

Conditions
Interventions
creatine monohydrate
Creatine will be taken at a dose of 150mg/kg/day of creatine base divided into 2 daily doses up to 39.7kg in body weight, after which dosing will be based on body surface area (BSA) at 4.69g/m2/day. Creatine will be administered orally as a chewable tablet provided by BioTechUSA™. Tablets are 2g and contain 0.9g of creatine monohydrate which is equivalent to 0.8g of creatine base.
ubiquinol
Coenzyme Q10 (CoQ10, ubiquinol) will be taken at a dose of 10mg/kg/day divided into 2 daily doses with a daily maximum of 500mg. CoQ10 will be administered orally in 50mg softgels containing 50mg of ubiquinol (Active Q®), provided by Tishcon Corporation.
glucose tablet
Creatine placebo will be in the form of a glucose tablet with identical appearance and taste to the active supplement. The number of tablets/day will be determined based on the dose of creatine required for each patient.
gel capsule
Ubiquinol placebo will be in the form of a gel capsule with identical appearance to the active supplement. The number of capsules/day will be determined based on the dose of ubiquinol required for each patient.
Exercise
Participants will be coached to hit 12,000 steps or 60 "active minutes" per day as logged by a FitBit (FitBit calculates active minutes as activities equivalent to moderate-to-vigorous physical activity (MVPA) done continuously for at least 10 minutes)
