Affected male children are normal at birth, but develop signs of muscle weakness before age 6, usually first affecting the legs and pelvis, causing difficulty getting up from the floor or a sitting position, and difficulty climbing stairs. Untreated boys are usually wheelchair dependent by age 12.
However, so far corticosteroid therapy is the only treatment that has been shown to increase muscle strength in boys already affected with symptoms of DMD.
Steroids can cause side effects, and there is wide variability whether doctors doctors prescribe prednisone or deflazacort, as well as the dosing, duration of steroid use or even whether steroids are prescribed at all.
A new study aims to answer some of these questions.
The study is looking to enroll boys aged 4-7 with genetically confirmed DMD who have not taken steroids before.
They will be included in the study for 3-5 years and receive either:
1. Prednisone 0.75mg/Kg/d, or
2. Prednisone 0.75mg/Kg/d 10days on then 10 days off, or
3. Deflazacort 0.9mg/Kg/d
They will need hospital visits every 3 months for the first 6 months, then every 6 months thereafter.
