Background ― The endometrial factor is important in miscarriage (MC) pathogenesis. Objective. To perform a morphofunctional evaluation of endometrium in the patients with uncertain MC cause in anamnesis. Material and methods ― We examined 48 women 23-40 yo [30 (27, 35)]: the main group consisted of 33 patients with early MC in their medical history, while the control group included 15 healthy fertile women. All women had an ovulatory menstrual cycle, normal levels of gonadotropic and thyroid hormones, prolactin, and androgens. Ultrasound and hormonal examinations, along with morphological investigation of endometrial biopsies were performed. Data presented as median with lower and upper quartiles – Me (LQ, UQ). Results ― In 64% (n=21) of women in the main group, we detected inferior secretory phase of their endometrial cycle, focal fibrosis of endometrial stroma; synchronous overexpression of estrogen (ER) and progesterone (PR) receptors in endometrial glands and stroma. ER in the glands was 240 (160, 280) vs. 130 (80, 210) in the stroma, while PR values were 270 (210, 290) in the glands vs. 270 (240, 280) in the stroma: differences from the control group were significant (p |
