ENDOMETRIAL POLYPS IN WOMEN OF REPRODUCTIVE AGE: CLINICAL AND PATHOGENE-TIC VARIATIONS.

The aim of the study was to study the relationship between the morphofunctional characteristics of the endometrium, hormonal homeostasis and microbiocenosis of the reproductive system in patients with endometrial polyps. The study involved 130 patients aged 18-35 years: 34 patients with endometrial polyps, 30 patients with micropolyps, 36 patients with endometrial polyps and micropolyps, 30 healthy women of the control group. Hysteroscopy was performed for women who had been suspected for endometrial polyps and who had infertility or repeated recurrent miscarriages. Endometrial samples from healthy women were obtained by aspiration biopsy. The endometrial sections were immunostained with monoclonal antibodies against the specific markers of plasmacytes (CD138), NK cells (CD56, CD16), pan-leukocytes (CD45), macrophages (CD68), cellular marker for proliferation (Ki-67), ER, PR. Bacteriological examination of the endometrium was performed by PCR and by cultivating aerobic and anaerobic microorganisms on special growth media. In all groups of women the content in blood serum for 3-5 day of a menstrual cycle of gonadotropic hormones (FSH, LH) and sex steroid hormones (estradiol, prolactin) was studied, for 21 days of a cycle estimated the content of progesterone. Level of an expression of receptors of progesterone and estrogen estimated in endometrium and at EP, also in І a cycle phase. Highlighted are separate clinical and pathogenetic variations of endometrial polyps: isolated polyps, micropolyps, polyps in conjunction with micropolyps. In the course of study, it was found that progesterone deficiency and local immune imbalance with severe hypofunctional NK cells against viral and fungal infestations result in excessive endometrial cell proliferation and development of an isolated polyp. The case of a polyp merging with micropolyps potentiates an active inflammatory process alongside all of the mechanisms mentioned above. Micropolyps as a macroscopic manifestation of an active inflammatory process in chronic endometritis are characterized by focal infiltrates of leukocytes (CD45), macrophages (CD68), plasmacells (CD138) and NK (CD56) cells, whose activity leads to excess abnormal proliferation of endometrium, even in the absence of hormone receptor disorders.
