Using the fluorescent treponemal antibody-absorption (FTA-ABS) test and the solid phase haemadsorption assay (SPHA) Treponema pallidum-specific IgA was found in the cerebrospinal fluid (CSF) of patients with neurosyphilis but not in those with late latent syphilis. The presence of T pallidum-specific IgA in the CSF may inhibit the antitreponemal activity of IgG and thus play some part in the pathogenesis of neurosyphilis.
运用荧光密螺旋体抗体吸收试验(FTA-ABS)和固相血细胞吸附试验(SPHA),发现神经梅毒患者的脑脊液(CSF)中存在梅毒螺旋体特异性IgA,而晚期潜伏梅毒患者的脑脊液中则未发现。脑脊液中梅毒螺旋体特异性IgA的存在可能会抑制IgG的抗梅毒螺旋体活性,从而在神经梅毒的发病机制中发挥一定作用。
