title: Anticentromere and anticentriole antibodies in the scleroderma spectrum.
abstract: We studied serum samples from 106 patients, including 80 in the scleroderma spectrum, by indirect immunofluorescent microscopy, using PtK1 rat kangaroo tissue culture cells as substrate. Anticentromere (Kinetochore) antibodies were present in 28 patients, and anticentriole antibodies were present in four patients. Anticentromere antibodies were usually present in patients with a benign, chronic form of systemic scleroderma, which has been termed the CREST (Calcinosis, Raynaud's phenomenon, esophageal involvement, sclerodactyly, and telangiectasia) syndrome. The four patients with a previously undescribed anticentriole antibody were all in the scleroderma spectrum. Possibly, these antibodies may have diagnostic and prognostic importance. Further, they will be useful in studying the structure and function of these cellular organelles.
