子宫内膜异位症患者腹腔液和血清IL-6、IL-15的临床分析

目的 探讨腹腔液和血清白细胞介素(IL)-6、IL-15与子宫内膜异位症(EM)的关系.方法 EM组为EM患者74例(其中Ⅰ～Ⅱ期26例,Ⅲ～Ⅳ期48例),对照组为卵巢良性畸胎瘤或行输卵管结扎术患者46例,采用双抗体夹心ELISA法测定两组患者腹腔液和血清IL-6、IL-15的水平.结果 EM组腹腔液和血清IL-6[(1017.81±361.98)ng/L和(455.47±161.52)ng/L]均高于对照组[(284.63±70.50)ng/L和(149.37±43.09)ng/L],EM组Ⅲ～Ⅳ期腹腔液和血清IL-6[(1253.44±189.63)ng/L和(556.50±93.34)ng/L]较Ⅰ～Ⅱ期[(582.81±107.75)ng/L和(268.96±63.48)ng/L]升高,差异均有统计学意义(P<0.01),腹腔液和血清IL-6呈正相关(r=0.950,P=0.01).EM组腹腔液IL-15[(333.45±63.94)ng/L]较对照组[(203.85±70.52)ng/L]升高,差异有统计学意义(P<0.01),EM组和对照组血清IL-15比较差异无统计学意义(P>0.05);EM组Ⅲ～Ⅳ期腹腔液和血清IL-15与Ⅰ～Ⅱ期比较,差异均无统计学意义(P>0.05).结论 腹腔液IL-6、IL-15的改变可能与EM的发病机制有关,血清IL-6可能成为诊断EM并评估其分期的无创性指标之一.

The clinical analysis of IL-6,IL-15 in peritoneal fluid and serum in patients with endometriosis

Objective To investigate the relationship between the levels of intedeukin(IL)-6, IL-15 and endometriosis (EM). Method The levels of IL-6, IL-15 in the peritoneal fluid (PF) and serum of 74 patients with EM (EM group) and 46 patients without EM (control group) were measured by double-an-tibody ELISA. Results Higher levels of IL-6 in PF and serum were observed in EM group [(1017.81±361.98) ng/L,(455.47±161.52) ng/L]than those in control group [(284.63±70.50) ng/L,(149.37± 43.09) ng/L], and there was significant difference (P<0.01). The levels of IL-6 in PF and serum in EM group with stage Ⅲ-Ⅳ [(1253.44±189.63) ng/L, (556.50±93.34) ng/L]were significantly higher than those in patients with stage Ⅰ-Ⅱ [(582.81±107.75) ng/L, (268.96±63.48) ng/L](P < 0.01). There was positive relationship between the levels of IL-6 in PF and serum (r=0.950, P=0.01). The levels of IL-15 in PF in EM group [(333.45±63.94) ng/L]were significantly higher than those in control group[(203.85± 70.52) ng/L](P<0.01). No significant difference was found in the levels of serum IL-15 between EM group and control group (P>0.05). No significant difference was observed either in the levels of IL-15 in PF and serum between patients with stsge Ⅲ-Ⅳ and stage of EM Ⅰ-Ⅱ (P>0.05). Conclusions The increase of IL-6, IL-15 in PF may contribute to the development of EM. Serum IL-6 levels are of clinical diagnostic value in patients with EM.
