【摘 要】 目的 探索抗核周因子(APF)、抗角蛋白抗体(AKA)、抗Sa抗体及抗RA33/36抗体检测对R A的早期诊断价值。方法 对未肯定诊断的关节痛/关节炎病人116例 进行上述四种抗体检测并随访观察。APF和AKA用间接免疫荧光法进行检测。抗Sa抗体和抗RA 33/36抗体用免疫印迹法检测。结果 对116例未肯定诊断的关节痛/ 关节炎患者随访4~18个月。APF阳性的29例中,最后确诊为RA 20例(69%);AKA30例中确诊 RA16例(53.3%);抗Sa抗体39例中确诊RA 19例(48.7%)。而APF、AKA和抗Sa抗体阴性组中 ,追随后确定为RA者比例不高,而发展为肯定非RA的患者明显高于阳性组,两组比较差异有显著性(P<0.05)。结论 四种自身抗体均可出现在RA确诊前的 病人中,任何两种以上自身抗体阳性对RA诊断早期有较高的价值。 【关键词】 关节炎,类风湿 抗核周因子 抗角蛋白抗体 抗RA33抗体 抗Sa抗体

【Abstract】 Objective To explore the diagnost ic value of antiperinuclear factor (APF),antikeratin antibody (AKA),anti-Sa ant ibody and anti-RA33/36 antibody in early RA patients.Methods One hundred and sixteen unclassified arthralgia/arthritis patients were studied a nd followed up for 4 to 8 months.APF and AKA were detected by indirect immunoflu orescence,anti-Sa and anti-RA33/36 antibodies were detected by immunoblotting. Results At the end of follow-up,20(69%) out of 29 APF positiv e patients were diagnosed to have RA,16(53.3%) out of 30 AKA positive and 19(4 8.7%) out of 39 anti-Sa positive patients were also diagnosed to have RA.The rates of APF,AKA and anti-Sa negative patients diagnosed to have RA were signif icantly lower than those of serum positive patients.Conclusion The 4 kinds of autoantibodies can be detected in early RA patients and have hi gh value on early diagnosis of RA. 【Key words】 Arthritis,rheumatoid Antiperinuclear factor Antikeratin antibody Anti-RA33 antibody Anti-Sa antibody
类风湿关节炎(RA)的诊断目前主要靠临床表现、X线改变和类风湿因子检测综合判断。到目 前为止还没有一个可作为常规的比较特异的诊断手段,特别是在疾病的早期阶段仍比较困难 ,而早期有效积极的治疗能很大程度上改善RA的预后,至少能延缓病情的进展[1] 。类风湿因子(RF)常用于诊断RA,但RF可出现于许多结缔组织病及其他疾病,诊断价值有限 [2]。本文对APF、AKA、抗Sa抗体和抗RA33/36抗体进行了研究,由此探讨四种自身 抗体对RA的早期诊断价值,希望能找到一些有助于[1] [2] [3] 下一页 上一个医学论文: 共刺激因子CD80在强直性脊柱炎肠道的表达 下一个医学论文: 系统性红斑狼疮多发家系与HLA致病单倍型研究
