本文报道抗双链DNA(dsDNA)抗体及抗核抗体(ANA)的消长同系统性红斑狼疮(SLE)的活动性的关系。以马疫锥虫血片免疫荧光(TE-IF)法检测9例活动期SLE患者dsDNA及ANA抗体滴度结果表明,抗体滴度与SLE活动性密切相关,活动期抗体滴度停留于高水平而于缓解期下降或阴转;临床复发前均有滴度持续上升阶段,而持续性滴度上升预 This article reports the relationship between the depletion of anti-dsDNA and anti-nuclear antibodies (ANA) and the activity of systemic lupus erythematosus (SLE). The titer of dsDNA and ANA antibodies in 9 active SLE patients detected by TE-IF method showed that the titer of antibody was closely related to SLE activity, and the active antibody titers stayed at high level But decreased in the remission or negative conversion; before the clinical recurrence of titers have continued to rise, while the sustained increase in titers
