【摘要】目的探讨复发性尖锐湿疣患者CD4+、CD8+T细胞、CD4+CD25+Foxp3+调节性T细胞(Treg细胞)的表达与临床意义。方法收集22例复发性尖锐湿疣患者(观察组)和24例正常对照者(对照组)的血清,采用流式细胞仪检测外周血CD4+、CD8+、CD4+/ CD8+T细胞和Treg细胞的表达水平。结果观察组CD4+、CD8+、CD4+/CD8+的表达明显低于对照组 (P<0.01),而Treg细胞的表达则明显高于对照组 (P<0.01)。观察组CD4+、CD8+、CD4+/CD8+的表达水平与患者的复发次数无显著相关性(P>0.05);Treg的表达水平与患者的复发次数呈显著正相关(P<0.01)。结论复发性尖锐湿疣患者T细胞免疫功能低下,Treg细胞的表达水平与尖锐湿疣的复发密切相关。

【Abstract】ObjectiveTo investigate the expressions and clinical significance of CD4+,CD8+T cells and CD4+CD25+Foxp3+regulatory T cells (Treg cells) of patients with recrudescent condyloma acuminatum.Methods22 cases of recrudescent condyloma acuminatum were selected as observation group,and 24 cases of normal controls as control group.Serum of both groups were collected,and flow cytometer was used to detect the expression levels of CD4+,CD8+,CD4+/ CD8+T cells and Treg cells in peripheral blood.Results The expression levels of CD4+, CD8+, CD4+/ CD8+T cells in the observation group were lower than those in the control group (P<0.01),while the expression levels of Treg cells in the former group were higher than those in the latter group (P<0.01).The recurrent frequency of the patients had no significant correlation with the expression level of CD4+,CD8+,CD4+/ CD8+T cells in the observation group(P>0.05),but it had significant positive correlation with the expression level of Treg cells(P<0.01).ConclusionPatients with recrudescent condyloma acuminatum have a low Treg cells immune function,and the recurrence of condyloma acuminatum has close relationship with the expression level of Treg cells.

尖锐湿疣(Condyloma acuminatum,CA)是由人类乳头瘤病毒 (Human papillomavirus,HPV)感染所致,是最常见的性传播疾病之一,该病容易复发,传染性强[1]。近年来,尖锐湿疣发病率逐年升高[2]。有研究显示患者细胞免疫功能可能与CA的发生、发展和转归关系密切[1,3]。本研究通过观察复发性CA患者细胞免疫水平,探讨CA的发病机制,以便用于指导CA的治疗、判断预后。
1资料与方法1.1一般资料所有患者来自我院2013年1月~2014年2月性病科门诊,按照就诊顺序收集22例复发性CA患者作为观察组。观察组男15例,女7例,年龄18~48岁,平均(36.28±9.70)岁,病程2个月~2年,平均(10.1±4.3)个月,复发次数2~6次。选择在我院体检中心健康体检正常者24例作为对照组,其中男10例,女14例,年龄18~50岁,平均(30.68±10.01)岁。两组年龄、性别等比较差异无统计学意义(P>0.05),具有可比性。
1.2病例入选和排除标准入选标准: ①符合尖锐湿疣的诊断标准:临床表现为外生殖器、会阴、肛周部位有典型的乳头状、菜花状或鸡冠状增生物;②5%醋酸白试验阳性;③复发2次或2次以上;④在本次治疗前未经任何治疗;⑤无结核、肿瘤、自身免疫性疾病,未合并其他性病,在治疗前1个月内没有全身应用抗病毒药、免疫调节剂、中药等药物。排……
