BACKGROUND Ectopic pregnancy is one of the most important causes of maternal deaths and fallopian tubes are the location of 95% of ectopic pregnancies. Elafin is a natural antimicrobial molecule that plays an important role as an anti-inflammatory agent in mucosal surfaces and has been found in the female reproductive tract. OBJECTIVES The aim of this study was to investigate elafin expression, in the fallopian tube mucosa of ectopic pregnancies compared to the normal tubes using immunohistochemistry (IHC) techniques and quantitative reverse transcription (qRT)-PCR. METHODS In this case-control study, uterine tube samples were obtained from patients with an indication for surgical removal of the tubes. The case group (n = 20) consisted of patients who were undergoing salpingectomy due to an ectopic pregnancy, the control group (n = 20) included patients who had a salpingectomy and hysterectomy. Using qRT-PCR and IHC, the expression of elafin was investigated in both study groups. RESULTS Immunohistochemical expression of elafin in the epithelium and connective tissue was significantly increased in the implantation site of the patients in comparison with the control group (P < 0.001). The level of elafin mRNA increased in the mucous membrane of the fallopian tube from patients with the ectopic pregnancy compared to the normal mucosa (P < 0.001). CONCLUSION Increasing expression of elafin during an ectopic pregnancy may be a mechanism for enhancing innate immune response and be involved in related pathological conditions such as infection and ectopic implantation.

与正常输卵管相比,异位输卵管妊娠输卵管中 elafin 表达的上调。

背景异位妊娠是孕产妇死亡的最重要原因之一,输卵管是95%的异位妊娠发生的部位。Elafin 是一种天然抗菌分子,在粘膜表面作为抗炎剂发挥重要作用,已在女性生殖道中发现。目的 本研究的目的是使用免疫组织化学 (IHC) 技术和定量逆转录 (qRT)-PCR 研究与正常输卵管相比异位妊娠输卵管黏膜中 elafin 的表达。方法 在这项病例对照研究中,从有手术切除管子指征的患者身上获取了输卵管样本。病例组(n = 20)由因异位妊娠而接受输卵管切除术的患者组成,对照组(n = 20)包括接受输卵管切除术和子宫切除术的患者。使用 qRT-PCR 和 IHC,研究了两个研究组中 elafin 的表达。结果 与对照组相比,患者植入部位上皮和结缔组织中elafin的免疫组织化学表达显着增加(P < 0.001)。与正常黏膜相比,异位妊娠患者输卵管黏膜中 elafin mRNA 的水平增加(P < 0.001)。结论 异位妊娠期间elafin表达增加可能是增强先天免疫反应的一种机制,并参与感染、异位着床等相关病理状况。在两个研究组中都研究了 elafin 的表达。结果 与对照组相比,患者植入部位上皮和结缔组织中elafin的免疫组化表达显着增加(P < 0.001)。与正常黏膜相比,异位妊娠患者输卵管黏膜中 elafin mRNA 的水平增加(P < 0.001)。结论 异位妊娠期间elafin表达增加可能是增强先天免疫反应的一种机制,并参与感染、异位着床等相关病理状况。在两个研究组中都研究了 elafin 的表达。结果 与对照组相比,患者植入部位上皮和结缔组织中elafin的免疫组化表达显着增加(P < 0.001)。与正常黏膜相比,异位妊娠患者输卵管黏膜中 elafin mRNA 的水平增加(P < 0.001)。结论 异位妊娠期间elafin表达增加可能是增强先天免疫反应的一种机制,并参与感染、异位着床等相关病理状况。结果 与对照组相比,患者植入部位上皮和结缔组织中elafin的免疫组化表达显着增加(P < 0.001)。与正常黏膜相比,异位妊娠患者输卵管黏膜中 elafin mRNA 的水平增加(P < 0.001)。结论 异位妊娠期间elafin表达增加可能是增强先天免疫反应的一种机制,并参与感染、异位着床等相关病理状况。结果 与对照组相比,患者植入部位上皮和结缔组织中elafin的免疫组化表达显着增加(P < 0.001)。与正常黏膜相比,异位妊娠患者输卵管黏膜中 elafin mRNA 的水平增加(P < 0.001)。结论 异位妊娠期间elafin表达增加可能是增强先天免疫反应的一种机制,并参与感染、异位着床等相关病理状况。
