Abstract:

Objective To evaluate the effect of 3 ELISA kits on detection of human fasciolasis. Methods Twenty?six serum samples from patients with fasciolasis,180 serum samples from patients with other parasitic diseases as well as 26 serum samples from healthy people were detected by ELISA kits which using soluble antigen of Fasciola gigantica,Fasciola hepatica(Fg?ELISA and Fh?ELISA)as well as IgG antigen ELISA detection kits made by DRG company in Germany. The effects of the 3 kits were eval? uated. Results The sensitivities of Fg?ELISA,Fh?ELISA,and DRG?ELISA were 100.0%,80.8%(95% CI:65.7%-95.9%) and 100.0%,respectively;the specificities of the three were 87.9%(95% CI:83.5%?92.4%),85.0% (95% CI:80.1%-89.9%) and 83.5%(95% CI:78.4%-88.6%),respectively,and Youden indexes of them were 0.88,0.66 and 0.84,respectively. The de? tection rate of Fg?ELISA(100%)was significantly higher than that of Fh?ELISA(80.8%) (P <0.05) . The A absolute value(A/ CO)of Fg?ELISA was 1.70,which was also significantly higher than the value of Fh?ELISA(1.18)(P < 0.000 1) . Conclusion Fg?ELISA has a good detection effect and low cost,and is more suitable than Fh?ELISA and DRG?ELISA for clinical sample tests as well as massive screening in fasciolasis endemic areas in southwest China.

摘要:

目的 目的 评价3种人体片形吸虫病ELISA试剂盒的检测效果。方法 方法 采用本研究室大片吸虫抗原、 肝片吸虫成虫可溶性抗原包被的人体片形吸虫病ELISA试剂盒 (Fg?ELISA和Fh?ELISA) 及德国DRG公司生产的人体片形吸虫IgG抗体 ELISA试剂盒 (DRG?ELISA), 分别检测26份大片吸虫患者血清、 180份其他寄生虫病患者血清和26份健康人血清, 评价3 种检测试剂盒的检测效果。 结果 结果 Fg?ELISA、 Fh?ELISA 和DRG?ELISA 3种检测盒的敏感性分别为100.0%、 80.8%(95% CI: 65.7%~95.9%) 和100.0%, 特异性分别为87.9%(95% CI: 83.5%~92.4%)、 85.0% (95% CI: 80.1%~89.9%) 和83.5% (95% CI: 78.4%~88.6%), 约登指数分别为0.88、 0.66和0.84。其中, Fg ?ELISA检出率(100%)明显高于Fh?ELISA (80.8%) (P < 0.05); Fg?ELISA 检测26例大片吸虫病患者血清的吸光度 (A) 绝对值 (A/ CO) 为1.70, 明显高于Fh?ELISA的 1.18(P < 0.000 1)。结论 结论 Fg?ELISA试剂盒检测效果较好, 且成本相对较低, 比Fh?ELISA和DRG?ELISA两法更适宜用于我国西南大片吸虫病流行区临床样本检测及大规模筛查。
