Autoantibodies in childhood scleroderma.

R M Bernstein, R S Pereira, A J Holden

    Annals of the Rheumatic Diseases
    |August 1, 1985
    PubMed
    Summary

    Childhood scleroderma presents varied symptoms. Antinuclear antibodies (ANA) are common, especially antinucleolar antibodies, but anticentromere antibodies are absent in pediatric cases.

    Area of Science:

    • Pediatric rheumatology
    • Immunology
    • Autoimmune diseases

    Background:

    • Childhood scleroderma exhibits diverse clinical manifestations, differing from adult presentations.
    • Autoantibodies play a crucial role in diagnosing and understanding autoimmune conditions like scleroderma.

    Purpose of the Study:

    • To investigate the prevalence and patterns of autoantibodies in children diagnosed with scleroderma.
    • To compare autoantibody profiles in childhood scleroderma with those typically observed in adult cases.

    Main Methods:

    • Analysis of serum samples from 19 children with scleroderma.
    • Detection of antinuclear antibodies (ANA) using HEp2 cell substrate.
    • Assessment of antinucleolar and anticentromere antibodies.
    • Enzyme-linked immunosorbent assays (ELISAs) for antibodies against collagen types I-V.

    Main Results:

    • Antinuclear antibodies (ANA) were frequently detected in children with scleroderma, similar to adult prevalence.
    • Antinucleolar antibodies were observed in 58% of cases, while anticentromere antibodies were not detected.
    • All seven children with diffuse scleroderma or acrosclerosis were ANA positive.
    • Eight of 12 children with localized disease tested positive for ANA.
    • Antibodies to collagen types I-V were normal in all childhood cases, unlike in adult scleroderma.

    Conclusions:

    • ANA, particularly antinucleolar antibodies, are significant biomarkers in childhood scleroderma.
    • The absence of anticentromere antibodies and normal collagen antibody levels differentiate pediatric from adult scleroderma.
    • Further research into specific autoantibody profiles can aid in understanding and managing pediatric scleroderma.
