Clinical features of anti-chromo antibodies associated with anti-centromere antibodies


Anti-chromo antibodies (AChA) are autoantibodies accompanying anti-centromere antibodies (ACA). We determined the frequency and clinical significance of AChA in autoimmune rheumatic diseases. Serum samples from 252 patients with rheumatic diseases were examined by immunoblotting with HeLa nuclear extract and with recombinant N-terminus of 25-kD chromo protein (p25). AChA were detected in 28 (36%) of 77 sera with ACA. AChA were found only in ACA-positive sera. Twenty-two (79%) of 28 recognized a recombinant N-terminal portion of p25, including the chromo domain which is conserved among species. AChA were related to leucopenia, thrombocytopenia, elevated erythrocyte sedimentation rate, and existence of Sjögren*s syndrome (SS). In ACA-positive patients, AChA might be a serologic indicator of systemic sclerosis (SSc), having features of systemic lupus erythematosus and/or SS or diseases other than SSc.

Keywords: anti-centromere antibodies, anti-chromo antibodies, rheumatic diseases, chromo domain, autoepitope
