OBSERVATION ON DYNAMICS OF CIRCULATING ANTIGEN FROM PATIENTS WITH CYSTICERCOSIS BEFORE AND AFTER TREATMENT

  • Online:1995-08-31 Published:2017-01-05

摘要: 以单克隆抗体双夹心ELISA(McAb-ELISA)检测脑囊虫病人用阿苯达唑治疗前后血清中循坏抗原(CAg)的动态变化,结果显示,病人经1-3个疗程的治疗,CAg的OD均值由治疗前的0.499依次下降为0.291、0.073和0.051,而CAg的阴转率随疗程的增加而提高,1个疗程后为20.0%,2个疗程后为57.9%,3个疗程后为87.5%。选择8例脑囊虫病人同步对比检测血清CAg和CAb在不同疗程后的变化,结果CAg水平下降明显,3个疗程后,除1例外,全部转阴,而CAb水平下降缓慢,无1例转阴。因此,CAg的检测可作为囊虫病的疗效考核方法。

Abstract: The dynamics of circulating antigen (CAg)level in sera from pat1ents with cysticercosis before and after albendazole treatment were detected by using monoclonal antibody-based double antibody sandwich EL1SA (McAb-ELISA). The results indicate that after the patients with cysticercosis had been treated for one, two and three treatment courses, the levels of CAg in sera decreased with the increase in the number of treatment courses, their average OD value dropped from 0. 499 before treatment to 0. 291, 0. 073 and 0. 051 after treatment, respectively, and the corresponding negative conversion rates of CAg detection were 20. 0%, 57. 9% and 87. 5%, respectively. Sera from eight patients who had received three courses of albendazole treatment were detected for CAg and CAb before and after treat ment. The results indicate that the CAb level dropped rather slowly after three courses of treatment as compared to CAg level. It is concluded that detecting circulating ant1gen might be used as a promising method for evaluating the drug efficacy.
