Abstract

Background: In the case of AUB, estrogen and progesterone exert their effects by acting on specific nuclei. Receptor proteins such as estrogen receptor (ER) and progesterone receptor (PR). And periodic changes in its expression have been shown in human uterine tissue. Immunohistochemistry (IHC). Immunohistochemistry using specific monoclonal antibodies estimate the content of the receptor at the cellular level and interpret their exact location and distribution.
Materials and Methods: A two-year descriptive study was conducted. There were a total of 50 cases clinically diagnosed with AUB who underwent hysterectomy and endometrial curettage, and 20 non-AUB controls were included in this study. IHC was performed for ER and PR receptors in all cases and controls.
Result: The age range was 29 to 65 years and the average age of the patients was 43.21 years. Out of 50 patients, 26 were pre-menopausal and 24 were post-menopausal, and the mean hemoglobin, fertility and bleeding duration were 10.34 g/dL, 2.8 and 8.4 days per cycle. The average thickness of the endometrium was 10.5 mm in the cases and 6.25 mm in the control group. Increasing endometrial thickness was statistically significantly related to AUB and increased ER and PR HSCORE in stroma and glands (p<0> Conclusion: In addition to pelvic ultrasound and histology, immunohistochemistry. ER and PR have the advantage of allowing these hormone receptors to localize to the tissue.
Endometrial aspiration samples and anxiliary tests in patient treatment allong with AUB. Endometrial hyperplasia is more common in patients with AUB. The concentration of estrogen and progesterone receptors is significantly higher. Therefore, the location and concentration of ER and PR receptors increases and this makes it possible for targeted therapies and avoid invasive surgical procedures using selective progesterone receptor modulators and progesterone antagonists in the treatment of patients with AUB and endometrial hyperplasia.
