摘要
目的探讨抗神经节苷脂抗体在神经精神性狼疮(NPSLE)中的意义。方法采用酶联免疫吸附试验(ELISA)法,检测68份血清(包括NPSLE患者33例,无神经精神症状的狼疮患者35例)和18例脑脊液(包括NPSLE患者10例,非NPSLE的狼疮患者8例)中的抗神经节苷脂抗体IgG和IgM。结果血清中抗神经节苷脂抗体IgG、IgM在系统性红斑狼疮患者中的阳性率分别为21%、24%,在NPSLE患者中的阳性率均为18%,在无神经精神症状的狼疮患者中的阳性率分别为22%、29%,二者在抗体水平和阳性率上差异无统计学意义(P〉0.05)。脑脊液中抗神经节苷脂抗体IgG、IgM在系统性红斑狼疮患者中的阳性率分别为10/18、9/18,在神经精神性狼疮患者中的阳性率均为7/10、8/10,在非NPSLE的狼疮患者中的阳性率分别为3/8、1/8,二者在抗体水平和阳性率上差异有统计学意义(P〈0.05)。结论脑脊液中AGA与NPSLE密切相关。
Objective The anti-ganglioside antibodies in neuropsychiatric lupus erythematosus (NPLE)IS studied in this study. Methods All 68 serum (33 with NPLE, 35 without neuropsychiatric lupus) and 18 cerebrospinal fluids (10 with NPLE, 8 without neuropsychiatric lupus) were examined for anti-ganglioside antibodies by ELISA method. Results The positive rates of AGA were 21% (IgG) and 24% (IgM) in patients with SLE. There was no significant difference between NPLE and no-NPLE in serum AGA level (P〉0.05). The positive rates of AGA were 10/18 (IgG) and 9/18 (IgM) in patients with SLE. There was significant difference of AGA between NPLE and no-NPLE in CSF (P〈0.05). Conclusion CSF anti-ganglioside antibodies may be helpful to clinical diagnosis of NPLE.
