子宫内膜异位症患者外周血干扰素γ、白细胞介素4和白细胞介素6的变化及其临床意义

目的 探讨子宫内膜异位症(EM)患者外周血干扰素γ(IFN-γ)、白细胞介素4(IL-4)和白细胞介素6(IL-6)的变化及其临床意义.方法 用双抗体夹心酶联免疫吸附(ELISA)法检测25例EM患者(EM组)及20例盆腔结构正常患者(对照组)外周血IFN-y、IL-4、IL-6水平.结果 EM组患者外周血IFN-γ[(109.64±26.79)ng/L]明显低于对照组[(155.17±30.36)ng/L](P＜0.05),IL-4[(33.52±8.69)ng/L]、IL-6[(44.12±3.57)ng/L]明显高于对照组[(22.52±6.54)、(15.12±2.63)ng/L](P＜0.05);IFN-γ/IL-4(3.27±1.45)、IFN-γ/IL-6(1.15±0.56)明显低于对照组(6.89±1.68、2.54±1.03)(P＜0.01或＜0.05).结论 EM患者有Th2细胞因子明显增多并占优势漂移的现象,Th1/Th2细胞因子失衡在EM的发病机制及疾病进展中可能具有重要的作用.

Abstract：

Objective To study the changes of interferon ( IFN )- γ ,interleukin(IL)-4 and IL-6 in endometriosis. Method The levels of peripheral blood IFN-γ ,IL-4 and IL-6 in 25 patients with endometriosis (EM group) and 20 normal adults (control group) were detected by enzyme linked immunosorbent assay (ELISA). Results The level of peripheral blood IFN- γ in EM group [(109.64±26.79 ) ng/L] was lower than that in control group [(155.17±30.36) ng/L] (P ＜ 0.05 ), IL-4[(33.52 ± 8.69)ng/L]and IL-6 [(44.12 ± 3.57) ng/L] were higher than those in control group [(22.52 ± 6.54), ( 15.12 ±2.63 )ng/L](P＜0.05 ).The ratio of IFN-γ/II-4(3.27±1.45 ) and IFN- γ/IL-6 ( 1.15 ± 0.56 ) in EM group were significantly lower than those in control group (6.89 ±1.68,2.54 ±1.03)(P ＜0.01 or ＜0.05).Conclusions Th1 cells shift toward Th2 cells in patients with endometriosis. Th1/Th2 ratio may be correlated with the pathogenesis of endometriosis.
