摘要:

目的: 探讨多房棘球绦虫(Echinococcus multilocularis, E.m.)原头节18 kDa、16 kDa抗原(E.m.18kDa 和E.m.16kDa) 诊断泡球蚴病的应用价值。方法: 应用免疫印迹法检测24 例泡球蚴病、55 例囊型包虫病、33 例囊虫病和30 份健康人血清对E.m.18kDa 和E.m.16kDa 的抗体反应, 同时用E.m.2-ELISA 试剂盒对比检测上述血清对E.m.2 的抗体反应。结果: 在免疫印迹试验中, E.m.18 kDa 和E.m.16kDa 均能被所有24 例(100%) 泡球蚴病人血清识别, 与囊型包虫病病人血清交叉反应率分别为16.4%和29.1% , 与囊虫病人血清交叉反应率分别为3.0%和33.3%。E.m.2-ELISA 检测泡球蚴病患者血清抗体阳性率为95.8%, 与囊型包虫病和囊虫病患者血清交叉反应率分别为23.6%和33.3%。健康人血清均不与E.m.18kDa、E.m.16kDa 或E.m.2 发生反应。结论: E.m.18kDa/16kDa, 特别是E.m.18kDa 对诊断泡球蚴病有高度敏感性和较强特异性, 可望成为泡球蚴病免疫诊断的候选抗原。

Abstract:

AIM: To study the usefulness of 18 kDa/16 kDa antigens in larval Echinococcus multilocularis, designated E. m. 18 kDa and E. m. 16 kDa, for immunodiagnosis of human alveolar echinococcosis. METHODS: Western blot analysis based on the detection of antibody responses against E. m. 18 kDa and E. m. 16 kDa and commercially available E. m. 2-ELISA were evaluated comparatively using 24 sera from patients with alveolar echinococcosis, 55 sera from patients with cystic echinococcosis, 33 sera from patients with cysticercosis and 30 sera from healthy controls. RESULTS: All 24 (100% ) sera from alvrolar echinoco-ccosis patients recognized both E. m. 18 kDa and E. m. 16 kDa in Western blotting, whereas 23 of them were positive in E. m. 2-ELISA. The cross-reactivity with sera from Cystic echinococcosis was 16.4% for E. m. 18 kDa, 29.1% for E. m. 16 kDa and 23.6% for E. m. 2, while the cross-reactivity with sera from Cysticercosis was 3.0% for E. m. 18 kDa, 33.3% for both E. m. 16 kDa and E. m. 2. None of the sera from healthy controls showed reactivity with E. m. 18 kDa, E. m. 16 kDa or E. m 2. CONCLUSION: Our findings confirmed the high potential of E. m. 18 kDa and E. m. 16 kDa for immunodiagnosis of alveolar echinococcosis, and E. m. 18 kDa in particular.
