The descriptive statistics were conducted in the study, and toluidine red unheated serum test (TRUST) titer responses to penicillin treatment in syphilis-infected pregnant women, and the associations with congenital syphilis were investigated. We divided the patients into two groups according to the history of anti-syphilis treatment before pregnancy (patients diagnosed with syphilis who had received anti-syphilis treatment before pregnancy, and patients screened and diagnosed with syphilis during pregnancy who had no previous history of anti-syphilis treatment).Results: The rate of congenital syphilis in this study was 6.2% (25/406). There was no significant difference in the rate of congenital syphilis between patients who received anti-syphilis treatment before pregnancy and those who did not. Secondary syphilis and high baseline serum TRUST titer (≥1:8) in pregnant women were independent risk factors for congenital syphilis.Conclusions: For the prevention of congenital syphilis, anti-syphilis treatment during pregnancy for syphilis seropositive pregnant women is needed, regardless of whether the patient has received anti-syphilis treatment before pregnancy, especially for those patients with secondary syphilis or high baseline serum TRUST titer, thus, timely surveillance, early diagnosis to timely treatment, and close syphilis reexamination during posttreatment follow-up, may help to reduce the above-mentioned risk factors for congenital syphilis.展开更多
目的：用化学发光微粒子免疫分析法（CM IA ）联合梅毒螺旋体明胶凝集试验（T PPA ）和甲苯胺红不加热血清试验（TRUST）检测梅毒抗体（TP-Ab），探讨CMIA在筛查梅毒螺旋体特异性抗体中的临床应用价值。方法采用CMIA对住院和门诊患者进...目的：用化学发光微粒子免疫分析法（CM IA ）联合梅毒螺旋体明胶凝集试验（T PPA ）和甲苯胺红不加热血清试验（TRUST）检测梅毒抗体（TP-Ab），探讨CMIA在筛查梅毒螺旋体特异性抗体中的临床应用价值。方法采用CMIA对住院和门诊患者进行TP-Ab筛查，阳性标本再进行TPPA和TRUST 的检测，对比分析3种检测方法的检验结果的符合率。结果25030例血清标本经CM IA筛查共检出T P-Ab阳性732例，检出率为2．9％。以TPPA和TRUST对阳性标本进行联合检测的阳性检出率分别为78．7％、37．2％。以 TPPA为标准参考方法， CM IA S/CO在1～＜9的阳性符合率为29．7％～90．1％，S/CO≥9的阳性符合率为100．0％。结论 CM IA可取代传统的非密螺旋体抗原血清试验用于高通量梅毒抗体的筛查。展开更多
