抗梅毒螺旋体主要抗体与RPR的关系探讨

目的 分析梅毒阳性血清抗TP15、17、47单组分抗体的检出情况并探讨其与梅毒心磷脂反应素的关系.方法 分别建立抗TP15、17、47 ELISA双抗体夹心法检测梅毒阳性血清,再用苍白密螺旋体颗粒(明胶)凝集试验(TPPA)法确定,同时快速血浆反应素试验(RPR)法测定抗心磷脂反应索阳性滴定度.结果 抗TP15、17、47与常规ELISA的阳性不符合率分别为15.2%,3.3%和5.1%,各组分抗体强度的分布不同;ELISA检测的OD值与TPPA检测时血清的抗体强度无相关性(r=0.073);比较3种抗TP单组分抗体的OD值在RPR阳性和阴性组的差异均有统计学意义.结论 抗TP15、17、47单组分抗体与ELISA有不同的阳性不符合率,ELISA与TPPA检测的血清抗体强度无相关性;RPR的阳性检出率为47.1%,3种抗TP单组分抗体均为阳性而RPR阳性组OD值低于阴性组.

Relationship Between Major Antibodies of Treponema pallidum and RPR

OBJECTIVE To analyze the results of Treponema pallidum positive serum single antibody including three antibodies(anti-TP15,anti-TP17,and anti-TP47),and to discuss the relationship between the results and cardiolipin(diphosphatidyl glycerol) reagin.METHODS Detecting T.pallidum positive serum by enzyme-linked immunosorbent assay(ELISA) with established anti-TP15,anti-TP17,and anti-TP47,respectively,and then,confirmed by TPPA,the titer of anticardiolipin reagin was measured by rapid plasma reagin test(RPR),sim...
