Hematological abnormalities in scleroderma. A study of 180 cases.

R A Frayha, L E Shulman, M B Stevens

    Acta Haematologica
    |January 1, 1980
    PubMed
    Summary

    Hematological abnormalities are common in scleroderma patients, affecting 25% with anemia and 14% with leukocytosis. These blood changes can signal disease complications or related conditions like lupus.

    Area of Science:

    • Rheumatology and Hematology
    • Connective Tissue Diseases
    • Autoimmune Disorders

    Background:

    • Scleroderma (systemic sclerosis) is a complex autoimmune disease characterized by fibrosis of the skin and internal organs.
    • Hematological abnormalities are recognized complications that can arise independently or in conjunction with other systemic conditions.
    • Understanding these blood-related issues is crucial for comprehensive patient management and diagnosis.

    Purpose of the Study:

    • To investigate the prevalence and potential causes of various hematological abnormalities in a cohort of scleroderma patients.
    • To correlate specific blood count changes with clinical manifestations and associated syndromes in scleroderma.

    Main Methods:

    • Retrospective analysis of hematological data from 180 patients diagnosed with scleroderma.
    • Correlation of findings with clinical features, including overlap syndromes (e.g., systemic lupus erythematosus), CREST syndrome, myopathy, and visceral involvement.

    Main Results:

    • Anemia was observed in 25% of patients, linked to chronic inflammation, bleeding telangiectases (CREST syndrome), malabsorption, and microangiopathic hemolysis.
    • Leukocytosis (14%) correlated with active myopathy and/or advanced visceral disease.
    • Leukopenia suggested overlap with systemic lupus erythematosus; thrombocytopenia indicated microangiopathy, while thrombocytosis was associated with arteritis or tumors.

    Conclusions:

    • Hematological abnormalities are frequent in scleroderma and serve as important indicators of disease activity, complications, or co-existing conditions.
    • Specific patterns of blood count changes can aid in diagnosing associated syndromes and guiding treatment strategies for scleroderma patients.
