The 'CREST' syndrome. Comparison with systemic sclerosis (scleroderma).

E E Velayos, A T Masi, M B Stevens

    Archives of Internal Medicine
    |November 1, 1979
    PubMed
    Summary

    CREST syndrome, a variant of systemic sclerosis, shares many features with scleroderma but presents with significantly less joint pain and inflammation. This highlights its unique position within the systemic sclerosis spectrum.

    Area of Science:

    • Rheumatology
    • Dermatology
    • Internal Medicine

    Background:

    • CREST syndrome (Calcinosis, Raynaud's phenomenon, Esophageal dysfunction, Sclerodactyly, Telangiectasia) is a condition related to systemic sclerosis.
    • Understanding the relationship between CREST syndrome and systemic sclerosis is crucial for diagnosis and management.

    Observation:

    • A study compared 13 CREST patients with 26 systemic sclerosis patients lacking full CREST criteria.
    • Key clinical features like Raynaud's phenomenon, digital changes, and esophageal issues showed no significant differences between groups.
    • Laboratory findings, including elevated ESR, were also similar across both groups.

    Findings:

    • CREST patients exhibited significantly lower frequencies of arthralgia (54%) and arthritis (15%) compared to systemic sclerosis patients (88% and 65%, respectively).

  • CREST syndrome predominantly affected women (all but one patient) and was exclusively observed in white individuals.
  • Most CREST patients presented with severe acrosclerosis, indicating a significant impact on their health.
  • Implications:

    • CREST syndrome and CRST syndrome appear to be closely related and part of the systemic sclerosis spectrum.
    • The distinct presentation of joint symptoms in CREST syndrome warrants further investigation within the broader context of systemic sclerosis.
    • These findings aid in differentiating and understanding the spectrum of systemic sclerosis and its variants.
