作者新近发现在舞蹈病患者和系统性红斑狼疮及其有关疾病的患者的抗磷脂抗体发生率增加。在原发性抗磷脂综合征的病人似乎也经常有发生舞蹈病者。有抗磷脂抗体的病人口服避孕药似乎不但增加血栓形成并发症的危险,而且也增加舞蹈病的危险。妊娠性舞蹈病看来尤其与这些抗体的存在有关。内源性激素和外来的激素与舞蹈病的发生有密切关系。 The authors have recently found an increased incidence of antiphospholipid antibodies in chorea patients and in patients with systemic lupus erythematosus and its related diseases. Patients with primary antiphospholipid syndrome often appear to have chorea. Oral contraceptives in patients with antiphospholipid antibodies appear to increase not only the risk of thrombotic complications but also the risk of chorea. Pregnancy chorea appears to be particularly associated with the presence of these antibodies. Endogenous hormones and foreign hormones are closely related to the occurrence of chorea.
