  1. Racial differences in scleroderma among women in Michigan.

    Article - En anglais

    Objective

    To examine racial differences in disease onset, extent, manifestations, and survival among women with scleroderma.

    Methods

    A retrospective cohort study of women with scleroderma, diagnosed in Michigan between 1980 and 1991, was conducted.

    Clinical, laboratory, and demographic data were abstracted from the patients'medical records.

    Results

    A total of 514 women with scleroderma were identified : 117 (23%) were black and 397 (77%) were white.

    Among black women, the mean age at diagnosis was lower (44.5 years versus 51.5 years ; P<0.001) and diffuse disease was more common (49.6% versus 24.9% ; P<0.001) than among white women.

    The overall incidence of scleroderma was 14.1 per million per year : 22.5 per million per year in black women versus 12.8 per million per year in white women (P<0.001).

    Pericarditis (P=0.009), pulmonary hypertension (P<0.001), pleural effusions (P=0.01), myositis (P=0.02), and an erythrocyte sedimentation rate>40 mm/hour (P<0.001) were more frequent among black women, while white women were more likely to have digital infarctions (P<0.001).

    Survival at 7 years from diagnosis was 72.5% among black women and 77.6% among white women.

    Age-adjusted survival was significantly reduced among black women (P=0.033), most likely because of increased diffuse involvement.

    Survival among those with renal or pulmonary involvement was also significantly reduced.
