目的

评价全自动免疫分析法检测抗核抗体谱在系统性红斑狼疮(SLE)中的价值。

方法

采用BioPlexTM 2200全自动免疫分析仪和酶联免疫吸附法(ELISA)检测30例SLE患者血清中dsDNA、Sm、RNP等抗体;采用BioPlexTM 2200全自动免疫分析仪检测109例SLE患者(SLE组)、109例结缔组织病患者(结缔组织病组)及33名健康对照者(对照组)血清中15项抗核抗体谱阳性率并比较3组的差异。比较2种检测方法的一致性。

结果

SLE组抗dsDNA、抗核染色质、抗核糖体P蛋白、Sm、SmRNP、RNP、RNP68、SSA、RNP-A、Ro60、Ro52、SSB的阳性率与结缔组织病组、对照组比较,差异均具有统计学意义(P均<0.05),CenB的阳性率与结缔组织病组、对照组比较,差异均无统计学意义(P均>0.05),Any ANAs与对照组比较,差异具有统计学意义。全自动分析法和酶联免疫吸附法检测Sm的阳性率差异有统计学意义(66.67% vs 56.67%,χ2=4.17,P=0.03),检测抗dsDNA、RNP、Ro60、Ro52、SSB、抗核糖体P蛋白的阳性率差异均无统计学意义(P均>0.05)。2种方法检测dsDNA、Ro60、SSB、抗核糖体P蛋白的一致性良好(Kappa值分别为0.79、0.87、0.76、0.80),检测Sm、RNP、Ro52的一致性一般(Kappa值分别为0.61、0.60、0.50)。

结论

BioPlexTM 2200全自动免疫分析仪检测抗核抗体谱对SLE的诊断具有一定价值,其检测能力与酶联免疫吸附法相似。

Objective

To evaluate the value of antinuclear antibody (ANA) spectrum detected with a fully automated BioPlex 2200 immunoassay analyzer in the diagnosis of systemic lupus erythematosus (SLE).

Methods

We used a fully automated BioPlexTM 2200 immunoassay analyzer and enzyme-linked immunosorbent assay (ELISA) method to detect dsDNA, Sm, and RNP antibodies in 30 cases of systemic lupus erythematosus. Fifteen ANAs were then detected with the fully automated BioPlexTM 2200 immunoassay analyzer in 251 serum samples (including 109 from patients with SLE, 109 from patients with connective tissue disease, and 33 from healthy controls) and statistically analyzed. Other laboratory indexes were tested using routine methods.

Results

The positive rates of anti-dsDNA, anti-nuclear chromatin, anti-po, Sm, SmRNP, RNP, RNP68, SSA, RNP-A, Ro60, Ro52, and SSB had significant differences between the connective tissue disease group and healthy control group (P<0.05). The positive rate of CenB in the SLE group was comparable to those of the connective tissue disease group and healthy control group (P>0.05). There was a significant difference in the positive rate of any ANAs between the SLE group and the control group (P<0.05), but there was no significant difference between the connective tissue group and healthy control group (P>0.05). The two methods had a good consistency in the detection of dsDNA, Ro60, SSB, and Po (Kappa=0.79, 0.87, 0.76, and 0.80, respectively), and a fair consistency in the detection of Sm, RNP, and Ro52 (Kappa=0.61, 0.60, and 0.50, respectively).

Conclusion

Detection of antinuclear antibody spectrum with a fully automated BioPlexTM 2200 immunoassay analyzer has appreciated clinical value in the diagnosis of SLE. The ability of flow matrix immunoluminescence assay to detect antinuclear antibody spectrum is comparable to that of ELISA.
