Keyword:  梅毒传染性流式细胞仪检测淋巴细胞亚群;
Abstract: 目的:检测RPR持续阳性经治梅毒患者外周血淋巴细胞亚群,探讨其传染性与细胞免疫的相关性.方法:应用流式细胞仪检测RPR持续阳性梅毒患者中38例IgM阳性和32例IgM阴性的患者外周血T细胞亚群及NK细胞,并以30例健康人作为对照组.结果:IgM阳性组外周血CD3、CD4和CD8细胞均高于对照组(P<0.05),而NK细胞低于对照组(P<0.001);IgM阴性组外周血CD3、CD4细胞低于对照组(P<0.05),而CD8细胞及NK细胞均高于对照组(P<0.05);两组之间外周血淋巴细胞亚群的检测结果相比,IgM阳性组CD3、CD4细胞高于IgM阴性组(P<0.001),NK细胞低于IgM阴性组(P<0.001),而CD8细胞相比差异无显著性(P>0.05).结论:RPR持续阳性梅毒患者存在明显的细胞免疫不平衡和免疫抑制;NK细胞显著降低可能是RPR持续阳性且具传染性的主要原因.
