[Study on anti-histone fraction antibodies in patients with rheumatic diseases]
By using Western blot method, we studied the antihistone fraction antibodies in sera of patients with rheumatic diseases. After analysed with SDS-PAGE, the histone could be separated into H1, H3, H2B, H2A and H4 fractions. The positive rate of anti-histone fraction antibodies was highest (82.1%) in systemic lupus erythematosus (SLE) patients, especially in active stage. In 28 SLE patients, the positive rates of anti-H2B, -H1, -H3, -H2A and -H4 were 78.6%, 60.7%, 50.0%, 35.7% and 7.1% respectively. The results revealed that the determination of anti-histone fraction antibodies was beneficial to the diagnosis of SLE.
