Importance of anti-centromere antibodies in the diagnosis of Sjögren's syndrome.

The purpose of the present study was to indicate that patients with anti-centromere antibodies (ACA) also experience ocular/oral dryness like patients with anti-Ro/SSA and/or anti-La/SSB antibodies (anti-SSA/SSB). A total of 80 patients with subjective ocular and/or oral dryness were classified into two groups, namely, anti-SSA/SSB-positive (anti-SSA/SSB [+]) group and ACA-positive (ACA [+]) group. The degree of ocular and oral dryness in ACA (+) patients is similar to that in anti-SSA/SSB (+) patients. On histopathological examination of the labial glands, the area of fibrosis was significantly larger in the ACA (+) group than in the anti-SSA/SSB (+) group. Thus, ACA (+) patients should be examined for Sjögren's syndrome. [ABSTRACT FROM AUTHOR]
