Abstract
X-linked chronic granulomatous disease (CGD), a defect of leukocyte bactericidal capacity, was seen in three generations of a large kindred. The association of discoid lupus erythematosus (DLE) with CGD was noted. Recurrent antigenic stimulation leading to autoantibody formation may explain the apparently increased frequency of DLE in female carriers of CGD. A screen for CGD, the nitroblue tetrazolium test, is suggested for females with DLE who have experienced suppurative infections or who have a family history of early childhood deaths or recurrent infections.
