摘要
为证实用日本血吸虫单克隆抗独特型抗体NP30制备的抗体检测试剂盒考核治疗效果的价值,采用双“抗原”夹心酶联免疫吸附试验,用NP30替代抗原,检测血吸虫病抗体。结果:该试剂盒对急性感染者的检出率为100%,慢性轻度感染者的检出率为61%,特异性为100%。急性感染和慢性感染的Youden指数(r)分别为1.0和0.61,慢性感染者与经典抗体检测法SEA/ELISA(0.60)的r无差别。用此试剂盒检测血吸虫病治疗后1a的血清,阴转率达100%,明显优于经典抗体检测法(43.6%)。结论:NP30检测的抗血吸虫抗体属短程抗体,该试剂盒具有与循环抗原检测相同的考核疗效价值。
This investigation is designed to evaluate the value in comment on the treatment effects of the diagnostic kit made by monoclonal anti idiotypic antibody NP30 of Schistosom japonicum . The antibody of Schistosoma japonica was detected by the “antigen sandwiched” ELISA. The antigen was replaced by NP30. The results revealed that the sensitivity was 61% in the mild and chronic infection and 100% in the acute infection; and that the specificity was 100%. The Youden index of the chronic infection was 0.61. There is no difference with classical antibody detection (SEA/ELISA 0.60). The correction index of conversion to negative rate in patients cured one year later was 100%. It was superior to the classical antibody detection(43.6%). It is suggested that the antibody detected with NP30 is self short life antibody of schistosomiasis . This test kit has the value in comment on the treatment effects equal to that of circulating antigen detection.
