OBJECTIVE: This study was planned to investigate whether expression levels of endometrial NF-κB1 and NFκB p65 changes in women with recurrent implantation failure (RIF). PATIENTS AND METHODS: The study group consists of 30 RIF patients having at least three previous failed IVF cycles. The control group comprises of 30 patients having one or no previous failed attempt. Endometrial samples were obtained from all participants during hysteroscopy at the late follicular phase. Samples underwent ELISA analysis and immunohistochemical staining. The semi-quantitative H-Score method was used for analyzing the intensity of endometrial NF-κB p65 expression. RESULTS: The concentrations of endometrial NF-κB1 were found to be significantly increased when compared to control subjects. Likewise, significantly increased NF-κB p65 immunoreactivity was detected in the cytoplasm of luminal and glandular epithelial cells. The H-Score of NF- κB p65 in RIF women was found to be significantly increased when compared to control group. CONCLUSIONS: Increased levels of NF-κB1 and NF-κB p65 in the endometrium of RIF women can disturb physiological inflammation which is known to be positive modulator of endometrial receptivity.
