  1. Incidence of systemic lupus erythematosus : race and gender differences.

    Article - En anglais


    To examine racial differences in the incidence of systemic lupus erythematosus (SLE).


    A population-based registry of SLE patients in Allegheny County, Pennsylvania, was used to identify incident cases of SLE diagnosed between January 1,1985 and December 31,1990, from 3 sources, by medical record review (University of Pittsburgh Lupus Databank, rheumatologists, and hospitals).

    Capture-recapture methods using log-linear models were used to estimate the level of case-finding and to calculate 95% confidence intervals (CI).

    Incidence rates were calculated per 100,000 population.


    A total of 191 definite and 78 probable incident cases of SLE were identified, and the overall annual incidence rates were 2.4 (95% CI 2.1-2.8) and 1.0 (95% CI 0.8-1.3), respectively.

    The crude incidence rates of definite SLE were 0.4 for white males, 3.5 for white females, 0.7 for African-American males, and 9.2 for African-American females.

    The annual incidence rates of definite SLE remained fairly constant over the study interval.

    African-American females with definite SLE had a younger mean age at diagnosis compared with white females (P<0.05).


    Our rates clearly confirm previous reports of an excess incidence of SLE among females compared with males and among African-Americans compared with whites.
