Dermatomyositis-polymyositis in children.

K M Goel, M King

    Scottish Medical Journal
    |January 1, 1986
    PubMed
    Summary

    Pediatric dermatomyositis and polymyositis cases show good prognosis with corticosteroid treatment. Early diagnosis using muscle weakness and skin rash is key, though lab tests can be normal.

    Area of Science:

    • Pediatric Rheumatology
    • Pediatric Dermatology
    • Neuromuscular Disorders

    Background:

    • Dermatomyositis and polymyositis are rare inflammatory myopathies affecting children.
    • Understanding the clinical presentation and treatment outcomes is crucial for pediatric care.

    Observation:

    • A review of sixteen pediatric cases (15 dermatomyositis, 1 polymyositis) was conducted.
    • Proximal muscle weakness and characteristic skin rash were primary diagnostic indicators.
    • Laboratory tests like creatine phosphokinase (CPK), electromyography (EMG), and muscle biopsy aided diagnosis but were not always definitive, even in acute phases.

    Findings:

    • Most children received high-dose corticosteroids initially, followed by long-term low-dose maintenance.
    • Two patients also received cytotoxic agents.
    • Thirteen of sixteen patients achieved remission.
    • One case of polymyositis remained active, and two dermatomyositis cases were fatal.
    • Only three patients experienced long-term disability from contractures and calcinosis.

    Implications:

    • The study suggests a generally favorable prognosis for childhood dermatomyositis with appropriate treatment.
    • Prompt diagnosis and management are essential to improve outcomes and minimize long-term complications.
    • Further research may explore optimal treatment strategies and predictors of prognosis in pediatric inflammatory myopathies.
