摘 要:目的:检测滴虫性阴道炎(trichomanasvaginitis,TV)患者阴道局部细胞因子白介素-2(interleukine-2,IL-2)、白介素-8(interleukine-8,IL-8)及白介素-13(interleukine-13,IL-13)的变化,探讨它们在疾病及机体免疫防御机制中的作用。方法:选取生育年龄女性滴虫性阴道炎患者40例(TV组)为研究组,同期选取健康体检无阴道炎症的健康育龄女性66例为对照组,用ELISA法检测这2组人群中阴道局部IL-2、IL-8、IL-13及免疫球蛋白E(immunoglobinE,IgE)的水平。结果:(1)与健康对照组阴道局部IL-2(7.24pg/ml)、IL-8(1796.99pg/ml)、IL-13(22.54pg/ml)水平相比,滴虫性阴道炎患者阴道局部的IL-2为8.80pg/ml,有升高趋势(P=0.11);IL-8为7119.00pg/ml,IL-13为36.43pg/ml,均显著升高(P(0.001,P(0.001);(2)滴虫性阴道炎患者阴道局部IL-2/IL-13显著下降(P(0.001);(3)与健康对照组IgE水平(0.89IU/ml)相比,滴虫性阴道炎组(1.05IU/ml)显著升高(P=0.008)。结论:(1)滴虫性阴道炎时阴道局部IL-2有升高趋势,IL-13及IgE升高,提示阴道局部细胞免疫及体液免疫在抗滴虫感染中均起作用;(2)滴虫性阴道炎时阴道局部IL-8升高提示阴道局部粘膜的先天免疫应答在抗滴虫感染中起重要作用;(3)IL-2/IL-13下降提示可能出现了Th1/Th2细胞的免疫功能失衡。Objective :To investigate the levels of interleukine-2 (IL-2), IL-8, IL-13 within cervicovaginal lavage fluid in the women with trichomonas vaginitis (TV), and analyze the relation between the cytokines and the host defense against TV. Method:Cervicovagial lavage fluid was collected from 40 trichomonas vaginitis patients (TV group) and 66 healthy women ( control grouop) of child-bearing age. The concentrations of IL-2,IL-8 ,IL-13 and immunoglobin E(IgE) were measured by enzyme-linked immunosorbent assay (ELISA). Results: ( 1 ) Compared to the median of IL-2(7.24pg/ml) ,IL-8(1796.99pg/ml) ,IL-13 (22.54pg/ml) in control group,IL-2 (8.80pg/ml) trended to be increased (P =0. 12),both IL-8 (7119.00pg/ml) and IL-13 (36. 43 pg/ml) were significantly increased ( P 〈 0.001, P 〈 0.001 ) in TV group. (2) The ratio of IL-2/IL-13 was significantly lower than control group in TV group,( P 〈 0. 001 ). (3) Compared to the control group, there was no change of the level of IgE in TV group ( P = 0. 401, 0. 008,respectively). Conclusions:The cell immunity and humoral immunity of vaginal mucosa play an important role in resistance trichomonas vaginalis infection. The innate immune response of vaginal mucosa play an important role in resistance trichomonas vaginalis infection. The ratio of Th1/Th2 may be inbalance in vaginal mucosa of TV patients.
