目的:探讨对神经精神性狼疮的发生和早期诊断有意义的免疫学指标。方法:对伴发神经精神性症状和不伴有神经精神性症状的104例红斑狼疮患者C3、C4、IgG、IgA、IgM、抗核抗体(Antinuclear antibody,ANA)、抗核糖体P蛋白(Anti-ribosome P a...目的:探讨对神经精神性狼疮的发生和早期诊断有意义的免疫学指标。方法:对伴发神经精神性症状和不伴有神经精神性症状的104例红斑狼疮患者C3、C4、IgG、IgA、IgM、抗核抗体(Antinuclear antibody,ANA)、抗核糖体P蛋白(Anti-ribosome P antibody,ARPA)、抗核糖核酸蛋白抗体(Nuclear ribonuclear protein antibody,anti-NRNP)、抗脑神经抗体(Anti-brainantibody,ABA)及抗双链DNA(anti-dsDNA)进行回顾性分析,并在NPLE组将患者按有无合并精神症状进行分组,考查精神症状与上述部分指标的关联。SPSS12.0进行数据处理。结果:ABA阳性例数在NPLE组(62例中51例阳性)分布明显高于非NPLE组(42例中12例阳性),在合并精神症状的NPLE组比无精神症状组比例高(χ2=4.885,P=0.027),其余各项指标组间比较均无显著性差异。结论:C3、C4水平的降低,IgG、IgA、IgM升高及ANA、APRA、anti-NRNP、anti-dsDNA阳性变化不具有NPLE诊断和预测特异性,是SLE免疫损伤的共有表现;ABA对NPLE的发生及NPLE伴发的精神症状的出现有重要作用。展开更多
