Clarissa Pilkington, M.B.B.S.
Severe clinical features, including severe muscle weakness, cutaneous or gastrointestinal ulcerations, interstitial lung disease and convulsions, would respond to intravenous pulse cyclophosphamide therapy.
Open label, retrospective

IMACS Core Set Measures Included:
Physician Global Activity-VAS, Patient Global Activity-VAS, Muscle Strength Testing-MMT, Functional Assessment Tools-CMAS, CHAQ, Laboratory-Muscle Enzymes, Extramuscular Assessment-Extramuscular Global Activity, MD Assessment of Outcome
Examined improvement in core set measures at 6 month and last follow-up evaluation.
Adverse event assessment
Key Trial Dates:
Supported by the Juvenile Dermatomyositis Research Centre and grants from the Cathal Hayes Research Foundation.
