【摘要】 目的探讨老年患者梅毒螺旋体(Treponema pallidum,TP)抗体阳性的临床价值。方法对98例老年人采用酶联免疫吸附试验(ELISA)筛查梅毒抗体阳性标本,分别进行梅毒螺旋体血球凝集试验(treponema pallidum hemagglutinationassay,TPHA)检测和快速血浆反应素诊断试验(rapid plasma regaining,RPR)检测,对实验结果进行统计分析。结果 98例TP-ELISA阳性标本,用TPHA法检测阳性48例,阳性符合率48.98%。RPR法检测阳性44例,该44例仅16例用TPHA确证阳性。结论老年人梅毒血清学试验阳性,只提示其体内有抗类脂抗体或抗TP抗体存在,不能作为感染梅毒螺旋体的绝对依据。更多还原

【Abstract】 Objective To investigate the clinical significance of positive anti- Treponema pallidum(TP) antibody in elderly patients.Methods The samples of positive Treponema pallidum antibody from 98 elderly patients were screened by enzyme linked immune adsorption assay(ELISA) before the positive samples underwent Treponema pallidum hemagglutination assay(TPHA) and rapid plasma regaining detection diagnostic tests(RPR).All the experimental results were statistically analyzed.Results Among the 98 TP -ELISA positive samples,TPHA was confirmed in 48 cases,the positive coincidence rate being 48.98%.RPR was detected in 44 cases,16 of whom were confirmed positive by TPHA.Conclusions The body of elderly patients has anti- lipid antibodies and anti-TP antibodies.The presence of positive Treponema pallidum antibody cannot be interpreted as hard evidence of infection with syphilis.更多还原
