Abstract： 目的探讨梅毒螺旋体IgM抗体蛋白印迹试验(Treponema pallidum IgM Western blot,TP-IgM-WB)在新生儿胎传梅毒早期诊断中的价值.方法对8例胎传梅毒新生儿(其母亲均为梅毒)进行TRUST、TPPA,FFA-ABS-19S-IgM和TP-IgM-WB 4种梅毒血清学检查,并结合临床对结果进行比较.结果8例中3例出现胎传梅毒的典型临床表现,包括典型皮肤损害,梅毒新生儿肺炎,伴发心、脑、肝、肾多脏器衰竭;另外5例无胎传梅毒的临床表现.梅毒血清学试验结果:所有8例TP-IgM-WB均为阳性:除1例外,7例FFA-ABS-19S-IgM试验为阳性;3例有症状的胎传梅毒及3例胎传潜伏梅毒中4种梅毒血清学试验均为阳性;1例TRUST和TPPA均阴性,但FTA-ABS-19S-IgM和TP-IgM-WB均阳性;1例FFA-ABS-19S-IgM阴性,但TRUST滴度是母亲的4倍,TPPA和TP-IgM-WB均阳性.结论梅毒螺旋体IgM抗体蛋白印迹试验可作为一种确诊试验应用于新生儿胎传梅毒,尤其是胎传潜伏梅毒的早期诊断.
