在不存在双链DNA抗体或(H2A - H2B)复合物抗体的情况下,针对组蛋白(H2A - H2B)-DNA复合物的抗体对硬皮病相关疾病比对狼疮更敏感且更具特异性。

Antibodies to histone (H2A-H2B)-DNA complexes in the absence of antibodies to double-stranded DNA or to (H2A-H2B) complexes are more sensitive and specific for scleroderma-related disorders than for lupus.

Abstract

OBJECTIVE

To assess the role of antibodies to histones H2A, H2B, and anti-double-stranded DNA which form (H2A-H2B)-DNA complexes in patients with scleroderma-related disorders.

METHODS

Antihistone antibodies were measured, by enzyme immunoassay, in 26 patients with scleroderma-related disorders, 100 patients with systemic lupus erythematosus (SLE), and 24 patients with rheumatoid arthritis.

RESULTS

Antibodies to histone (H2A-H2B)-DNA complex were more commonly seen in patients with scleroderma-related disorders than in those with SLE (P < 0.0001).

CONCLUSION

Scleroderma-related disorders should be included among conditions in which various types of antihistone antibodies are produced. A hypothesis to account for this finding is discussed.

摘要

目的

评估抗组蛋白H2A、H2B抗体以及形成(H2A-H2B)-DNA复合物的抗双链DNA抗体在硬皮病相关疾病患者中的作用。

方法

采用酶免疫分析法检测26例硬皮病相关疾病患者、100例系统性红斑狼疮(SLE)患者和24例类风湿关节炎患者的抗组蛋白抗体。

结果

与SLE患者相比,硬皮病相关疾病患者中更常见抗(H2A-H2B)-DNA复合物组蛋白抗体(P < 0.0001)。

结论

硬皮病相关疾病应被纳入可产生各种抗组蛋白抗体的疾病范畴。文中讨论了对这一发现的一种解释假说。
