摘　　要：目的:探究活动性梅毒患者梅毒血清特异性抗体水平(TPAb)与体内免疫球蛋白A/E/M/G(IgA/E/M/G)及IgG亚型的相关性,为临床梅毒的综合诊疗与预后评估提供依据。方法:选取2023年就诊于苏州大学附属第一医院的活动性梅毒患者,根据梅毒甲苯胺红不加热血清试验(TRUST)分为1∶4+与1∶16+两组,另选取健康对照组,均进行化学发光微粒子免疫检测(CMIA)测定TPAb,免疫比浊法测定IgA/E/M/G及IgG1/2/3/4含量。结果:本次共纳入活动性梅毒患者206例(男性125例,女性81例),年龄(46.05±19.58)岁。相对健康对照组,可见活动性梅毒组IgG2降低,TPAb、IgA/E/M/G和IgG1/3/4水平均升高,其中TPAb、IgE、IgG1/2/3水平差异具有统计学意义(P<0.05)。相比于健康对照组,TRUST 1∶4+组TPAb、IgE、IgG2差异具有统计学意义,TPAb与IgE、IgG2/4存在相关性;而TRUST 1∶16+组TPAb、IgA/E/M/G、IgG1/2/3水平差异均具有统计学意义,TPAb与IgE、IgG4存在相关性(P<0.05)。另外,TRUST阳性组之间的TPAb、IgG和IgG1/3水平差异具有统计学意义(P<0.05)。结论:不同TRUST滴度的活动性梅毒患者TPAb与Ig水平存在较大差异,TPAb联合Ig可用于监测梅毒活动性强弱,IgA/M/G及IgG1/3可能成为候选生物标志物。Objective:To investigate the correlation between the level of treponema pallidum specific antibodies(TPAb)and immunoglobulin A/E/M/G(IgA/E/M/G)and IgG subtypes in active syphilis patients,so as to provide a basis for the comprehensive diagnosis and treatment and prognosis evaluation of clinical syphilis.Methods:Active syphilis patients admitted to the First Affiliated Hospital of Soochow University in 2023 were divided into 1∶4+and 1∶16+groups according to the syphilis toluidine red unheated serum test(TRUST),and healthy control group were selected for the detection of TPAb by chemiluminescence microparticle immunoassay(CMIA).The contents of IgA/E/M/G and IgG1/2/3/4 were determined by immunoturbidimetry.Results:A total of 206 patients with active syphilis(125 males and 81 females)aged(46.05±19.58)years were included in this study.Compared with the healthy control group,IgG2 was decreased and TPAb,IgA/E/M/G and IgG1/3/4 levels were increased in the active syphilis group,with statistically significant differences in TPAb,IgE and IgG1/2/3 levels(P<0.05).Compared with the healthy control group,TRUST 1∶4+group had statistical differences in TPAb,IgE and IgG2,and TPAb was significantly correlated with IgE and IgG2/4.The levels of TPAb,IgA/E/M/G and IgG1/2/3 in TRUST 1∶16+group were statistically significant,and TPAb was significantly correlated with IgE and IgG4(P<0.05).In addition,there were significant differences in TPAb,IgG and IgG1/3 between the two positive groups(P<0.05).Conclu⁃sion:The levels of TPAb and Ig in active syphilis patients with different TRUST titers are significantly different.TPAb combined with Ig can be used to monitor the strength of syphilis activity,IgA/M/G and IgG1/3 may be candidate biomarkers.
