Current view of the management of patients with endometrial hyperplasia: A review
Khachatryan A.S., Dobrokhotova Y.E., Il'ina I.Y., Kazantsev S.N.
Abstract

Endometrial hyperplasia (EH) is a spectrum of morphological changes in the endometrium characterized by the proliferation of glands and an increase in the gland-stromal ratio. The relevance of this disease is due to its high prevalence (10–55%). The clinical significance of EH is related to the increased risk of endometrioid cancer. One of the leading causes of EH is absolute or relative hyperestrogenism and progesterone deficiency that does not eliminate the proliferative effect of estrogens. The risk group for EH includes women with early menarche, late menopause, infertility, anovulation, polycystic ovary syndrome, obesity, type 2 diabetes mellitus, hypertension, Lynch syndrome, estrogen-producing ovarian tumors, as well as those receiving estrogen monotherapy or tamoxifen. Most leading experts believe that therapy should include surgery followed by drug therapy aimed at eliminating risk factors to reduce the risk of EH recurrence. Despite numerous research findings demonstrating the benefits of a particular treatment modality and the consequent presence of these modalities in clinical guidelines, the potential benefits of alternative therapies are still being discussed. This issue requires further study and the selection of optimal treatment regimens for patients with EH.

Ostrina S.Y., Serova O.F., Rudakova E.B., Fedorova E. .
Abstract

Reproductive medicine is actively developing, and new methods, drugs, and protocols are being developed and introduced for the treatment of infertility. Assisted reproductive technologies (ART) are the most effective methods. In ART protocols, ovarian stimulation (OS) is based on gonadotropin use. The choice of the starting dose of gonadotropin is a critical factor in the successful OS and the effectiveness of ART programs. The article describes the development history of gonadotropins and provides current data on their use in ART programs. The use of biosimilars of follitropin alfa in OS is discussed, and the effectiveness of its Russian biosimilar is also addressed.

Features of the reproductive function of girls and women with rheumatoid arthritis: A review
Kazakova A.V., Santalova G.V., Kartashova P.V., Poretskova G.Y., Dufinets I.E.
Abstract

Rheumatoid arthritis is one of the most common and severe autoimmune diseases. The prevalence of rheumatoid arthritis among adults in different geographical areas of the world ranges from 0.5 to 2%. The prevalence of juvenile rheumatoid arthritis is approximately 6 per 10 thousand children. The disease occurs 2 times more often in girls than in boys. Some studies have demonstrated a possible effect of high cumulative doses of methotrexate on ovarian function in patients with systemic lupus erythematosus, but further studies are needed to confirm this effect. The analysis of literature data allowed us to identify prognostically significant factors in the development of autoimmune ovarian failure in patients of reproductive age with rheumatic pathology, and to note the fact that there is missing information about the state of the reproductive system in female patients with juvenile arthritis.

Orazov M.R., Radzinskiy V.E., Khamoshina M.B., Orekhov R.E., Ermakov V.V.
Abstract

Aim. To evaluate the effect of a combined oral contraceptive (COC) containing estetrol and drospirenone on the sexual function of women using it.

Materials and methods. A total of 251 women aged 21–35 years (mean age, 25.30±2.82 years) referred for contraceptive fitting were included in the study (ICD-10: Z30.0 General contraceptive advice and counseling, Z30.4 Contraceptive drug monitoring). Women in the study cohort used the original formulation containing 15 mg estetrol and 3 mg drospirenone in a 24+4 regimen for contraceptive purposes, according to the current instructions. All female participants (n=251) were assessed for sexual function at baseline, 6 and 12 months using FSFI (The Female Sexual Function Index), FSDS-R (The Female Sexual Distress Scale-Revised) and SQoL-F (The Sexual Quality of Life-Female) scales.

Study design. An open, independent, prospective observational study.

Results. Women taking COC containing estetrol 15 mg and drospirenone 3 mg maintained a baseline high level of sexual satisfaction (p>0.05) throughout the study, as assessed by FSFI, SQoL-F and FSDS-R scales.

Conclusion. The results obtained indicate that there is no negative effect of COC containing 15 mg estetrol and 3 mg drospirenonone on the sexual function of women. High contraceptive efficacy of the drug was confirmed.

Characteristics of expression of proteomic markers in women with “thin” endometrium and their importance for the therapeutic effects of the use of exogenous estradiol: A prospective cohort comparative study
Aganezova N.V., Aganezov S.S., Gogichashvili K.E.
Abstract

Aim. To analyze the relationship between the expression of proteomic markers [estrogen (ER) and progesterone (PR) receptors, LIF, FOXA1, FOXA2] of endometrial receptivity and indicators of the levels of sex steroids [estradiol (E2) and progesterone (P)] in the peripheral blood during the “implantation window” in women with a history of reproductive dysfunction with “thin” endometrium (TE) and evaluate their significance for the therapeutic effect of using estradiol drugs.

Materials and methods. The prospective cohort comparative study was conducted. The main group included 52 patients with TE (<7 mm according to ultrasound on preovulatory days), the comparison group consisted of 62 women with normal endometrial thickness (≥7 mm according to ultrasound), women of both groups with reproductive dysfunctions of unknown reason; the control group included 16 healthy women. Aspiration biopsy of the endometrium was performed on the 6–8 days after ovulation (LH +6–8), as well as venipuncture to obtain a sample of peripheral blood to determine the E2, P levels. A combined histological and immunohistochemical study of endometrial samples was performed (ER, PR, LIF, FOXA1, FOXA2). The therapeutic effects of estradiol drugs were assessed in a cohort of women from the main group with TE (n=16 out of 26, those who have not changed their reproductive plans).

Results. All women had ovulatory values of progesterone [P≥16.1 nmol/l (LH +6–8)] and normoestrogenemia in the blood (p>0.05). According to the results of the correlation analysis, there were no associations between the E2, P levels and the value of M-echo, and no relationships were found between the E2, P levels and the expression of ER, PR, LIF, FOX-proteins. It was revealed that there are significant positive relationships between M-echo and FOXA2 expression in the endometrium (r=0.422; p<0.001). Conditional threshold values for the ER, PR expression (LH +6–8) were determined, the excess of which is associated with abnormal expression of LIF, FOX-proteins: for PR in the glands – 105 and 285, for ER in glands – 145, for ER in the stroma – 155. It was found that usual doses of estradiol drugs (1–1.5 mg/day) are capable of increasing endometrial proliferation in women with TE, provided that the expression of ER, PR, LIF, FOX-proteins in their endometrium is similar to healthy women. Increased doses of estradiol drugs (4 mg/day) in women with TE had a significant effect in the form of an increase M-echo value and/or pregnancy in cases where the endometrial expression of LIF, FOX-proteins was comparable with healthy women, even in the presence of hormone-receptor interactions in the endometrium that are different from healthy women. Spontaneous pregnancy in participants of the main group with hypoplastic endometrium in our study occurred in 5 women in whom the expression characteristics of FOXA1 and/or FOXA2 in the endometrium were comparable to healthy women.

Conclusion. TE is not the only marker of an imbalance of proteomic molecules, but it determines a greater likelihood of impaired expression of ER, PR, LIF, FOX-proteins in the endometrium. In women with an unclear reason of fertility disorders, it is necessary to conduct an in-depth examination of endometrial samples. Characteristics of endometrial expression ER, PR, LIF, FOX-proteins and the usefulness of hormone-receptor interactions in the TE in women with a history of reproductive disorders can be markers for predicting the effectiveness of the use of exogenous estradiol drugs in women in order to enhance endometrial proliferation with an initially low M-echo.

Clinical and history features of patients with recurrent deep endometriosis: A retrospective study
Senina D.N., Pashaeva S.A., Kulakova Y.A., Chuprynin V.D., Asaturova A.V., Ezhova L.S., Buralkina N.A.
Abstract

Aim. To identify clinical and history features of patients with recurrent deep endometriosis (RDE).

Materials and methods. A retrospective study of clinical and history data of 200 patients with DE undergoing surgical treatment at the Department of General Surgery of the Kulakov National Medical Research Center for Obstetrics, Gynecology and Perinatology in 2020–2021. Group 1 included 80 patients with RDE, group 2 included 120 patients with newly diagnosed DE. All patients underwent surgical treatment followed by immunohistochemical examination and DE confirmation.

Results. An association was found between the young age of the patient at the time of the first surgery and the type of endometriosis. It was found that women with a history of endometriosis surgery in early reproductive years (29.22±5.3 years) are at risk of recurrent endometriosis. Two or more surgeries were reported in 33.7% of RDE patients. In 90.2% of patients, endometriosis recurred with clinical manifestations; in 9.8%, it was asymptomatic and diagnosed on pelvic ultrasound. The group of RDE patients showed a longer period of infertility (5.432±3.53 years) than the group with newly diagnosed DE (2.953±1.29 years). It was found that the surgeries performed in RDE patients were longer, more complex, and associated with more blood loss. Intestinal resection, ureterolysis, adhesiolysis, and salpingectomy were significantly more common in the RDE group than in patients without a history of endometriosis surgery.

Conclusion. In most cases, RDE is clinically manifested, rarely asymptomatic and diagnosed by visualization methods. Patients with a history of surgery at a younger age are at risk of RDE, and their surgical interventions are more complicated with more blood loss. Currently, surgical treatment of DE is the optimal method; however, it has serious disadvantages with severe and even life-threatening postoperative complications.

Stupin D.A., Kolesnikova L.I., Semendyaev A.A., Darenskaya M.A., Tukhieva D.V., Bystrova E.S., Kuryshova K.V., Gus A.I.
Abstract

Aim. To evaluate the clinical efficacy of complex antioxidant therapy (CAT) in the treatment of patients with pelvic varicose veins (PVV).

Materials and methods. Patients with PVV (n=150) were divided into groups 1 and 2 of 75 subjects; the groups were comparable. Treatment in both groups included standard therapy with one of the venotropic agents (60 days). Patients of group 1 additionally received CAT for 30 days (1 course), in total 3 courses with 2-month intervals.

Results. When assessing the parameters of the lipoperoxidation system (antioxidant protection) in group 1 during CAT combined with standard venotropic therapy, there was a statistically significant decrease in the levels of lipid hydroperoxides (p<0.0001), diene conjugates (p=0.001), malonic dialdehyde (p<0.0001), an increase in the levels of catalase (p<0.0001), superoxide dismutase (p<0.0001), glutathione peroxidase (p<0.0001), glutathione reductase (p<0.0001), glutathione-S-transferase (p=0.002) and the reduced glutathione content (p=0.032) compared to levels before treatment. The above group showed a decrease in the diameter of the pelvic varicose veins: internal iliac (p<0.001), ovarian (p<0.0001) and arcuate (p<0.001), an increase in their blood flow velocity (p=0.003, 0.041, and 0.040, respectively), a decrease in the duration of retrograde flow to 0.3 cm. There was a decrease in pelvic pain (p<0.0001), dysmenorrhea (p=0.024), dyspareunia (p=0.037), the frequency of irregular menstruation (p=0.031), an improvement in quality of life (p=0.047), pregnancy rate (p=0.013), the number of live births (p=0.004), and the duration of remission (p=0.047).

Conclusion. The use of a combination of antioxidants superoxide dismutase 250 mg 2 times a day, acetyl-glutathione at 100 mg 2 times a day, and astaxanthin 400 mg/day for 30 days in 3 courses with 2-month intervals combined with venotropic therapy can significantly improve the treatment outcomes of patients with PVV.

Zhevlakova M.M., Rusina E.I., Shelaeva E.V., Yarmolinskaya M.I.
Abstract

Background. Paraurethral injection of bulking agents in women is one of the minimally invasive technologies for the treatment of stress urinary incontinence (SUI). The effectiveness and safety of this method depend on the properties of injected substance.

Aim. To evaluate the results of paraurethral injections of 1,4-butanediol diglycidyl ether crosslinked high-density hyaluronic acid (EsteFILL® intim) in the treatment of SUI in women of reproductive and perimenopausal age.

Materials and methods. We examined 18 patients aged 45.8±5.0 years with mild SUI in combination with grade I–II genital prolapse. After general clinical and special studies (urination diaries, King and PISQ-12 questionnaires, cough test, complex urodynamic study, urethrovesical segment and pelvic floor ultrasound with compression elastography) paraurethral injection of 4.0 ml EsteFILL® intim drug was performed. The results of therapy were studied 1 and 6 months after the procedure.

Results. It was found that the injection of the drug contributed to an increase in the stiffness of paraurethral tissues by 1.5 times within 6 months after injection. According to the results of elastography before treatment, the average value of the strain ratio of paraurethral tissues of the proximal posterior wall of the urethra was 0.66±0.46 (0.42–0.91), after 1 and 6 months – 0.99±0.45 (0.76–1.23) and 1.00±0.36 (0.78–1.22) respectively; p=0.009 and 0.018. The effectiveness of EsteFILL® intim drug in the treatment of mild SUI in women after 1 and 6 months according to the results of a cough test was 88.2 and 71.4%, according to urination diaries – 88.9 and 66.7% respectively. During the entire observation period the patients noted a decrease in the degree of discomfort due to SUI and an improvement in the quality of life.

Conclusion. Paraurethral injection of EsteFILL® intim drug helps to increase the stiffness of the urethra supporting structures in patients with SUI. This method of treating SUI is effective for women of reproductive and perimenopausal age with mild severity disease, who do not plan surgical treatment, are interested in achieving a quick result of therapy and are informed that the effect decreases over time after the procedure.

Combined treatment of postmenopausal patients with pelvic organ prolapse and genitourinary syndrome
Dobrokhotova Y.E., Lapina I.A., Tyan A.G., Taranov V.V., Chirvon T.G., Glebov N.V., Kaykova O.V., Malakhova A.A., Gomzikova V.M., Mahonina E.S., Olkhovskaya M.A.
Abstract

Background. Colpoptosis combined with stress urinary incontinence is one of the most common conditions in postmenopausal women. Menopause is also associated with the risk of genitourinary syndrome due to estrogen deficiency. Despite the variety of options for surgical correction of genital prolapse and urinary incontinence, there is no universal technique. The use of vaginal approach in pelvic floor surgery is associated with several controversies regarding the rates of recurrence and mesh-associated complications. Studies of the state of the endothelium in menopause have demonstrated a close relationship between age-related features and the frequency of adverse clinical outcomes, which requires an optimal intervention not only on the hormonal status but also on the microcirculatory system.

Aim. To improve the principles of complex treatment of pelvic organ prolapse and genitourinary syndrome in postmenopausal patients.

Materials and methods. The study included 48 postmenopausal patients with genital prolapse of stage II and above according to the POP-Q classification. All patients received continuous menopausal hormone therapy (MHT) with a combined estrogen-progestogen agent. The patients in group 1 (n=24) received MHT according to clinical guidelines for managing patients with genitourinary syndrome. The patients in group 2 (n=24), in addition to MHT, received sulodexide containing glucurono-2-amino-2-deoxyglucoglucan sulfate before the intended surgical treatment and for 30 days after surgery. Correction of colpocystocele, proctocele and stress urinary incontinence was performed using anterior and posterior colporrhaphy, perineoplasty, and urethral sling placement in case of stress urinary incontinence.

Results. Six months after surgical treatment, signs of genital prolapse recurrence were detected in 3 patients (12.5%) in group 1, and 1 patient (4.2%) showed signs of mesh-associated complications (implant extrusion) after urethral sling placement. In group 2, only 4.2% of patients (n=1) showed signs of recurrence of stage II cystocele. All patients who underwent urethral sling surgery reported improved urinary incontinence (n=10). During complex therapy, 3 months after surgery, a more significant improvement of endothelial dysfunction markers was noted in group 2 patients (homocysteine level in group 1 after treatment was 12.27±0.34, in group 2 – 8.34±0.24).

Conclusions. Combination therapy of genitourinary syndrome and genital prolapse using MHT, endotheliotropic drugs and vaginal surgical approach in postmenopausal patients contributes to effective and safe treatment associated with minimal risk of complications and recurrence rate. Endothelial dysfunction correction is an essential step in planning surgical intervention in menopausal patients, which contributes to improving tissue repair in the postoperative period.

Uterine artery embolization in the treatment of uterine fibroids and the preservation of reproductive health in women 40 years of age and older: A retrospective study
Solovyeva A.V., Chegus L.A., Aleynikova E.Y., Semenchenko S.I., Menshikh O.I., Kasparova A.E.
Abstract

Aim. To evaluate the effect of uterine artery embolization (UAE) on reproductive health in women 40 years and older.

Materials and methods. A retrospective study was conducted at the perinatal center of the District Clinical Hospital of Khanty-Mansiysk. Patients were divided into two groups: the main group (group 1; n=57) included women with uterine fibroids after UAE, and the control group (group 2; n=42) included women without a history of uterine fibroids.

Results. Women with uterine fibroids were statistically more likely to have grade 1 obesity (χ2=4.39; p=0.04) and less likely to have normal body weight (χ2=8.73; p=0.00) compared to women without fibroids. Smoking increased the risk of uterine fibroids twofold (χ2=4.49; p=0.03; odds ratio 1.97; confidence interval 0.64-6.11). More women with uterine fibroids had a history of abortions (n=42; 73.7%) than those without uterine fibroids (n=19; 45.2%; χ2=8.27; p=0.01). The most common gynecological comorbidities in women with uterine fibroids included inflammatory disease of the uterus (N71), endometrial polyp (N84), and endometriosis (N80); p<0.05. The most common extragenital diseases in patients with uterine fibroids included thyroid disease, hypertension, and iron deficiency anemia (p<0.05). Contour SE embolization agent with spherical particles was more often associated with pain (χ2=0.18; p=0.67) and less often with fever (χ2=4.47; p=0.03). There was a decrease in the number of short menstrual cycles (less than 24 days) from the moment before surgical treatment and after 24 months (χ2=34.580; p<0.001) and an increase in the number of cycles of 24–38 days (χ2=14.887; p=0.005). At 24 months after UAE, there were more women with a menstrual period of less than 3 days (χ2=10.385; p=0.035) and fewer with a menstrual period of more than 8 days (χ2=34.573; p<0.001). Ultrasound showed a decreased ovarian reserve at 6, 12 and 24 months after UAE (p<0.05).

Conclusion. When assessing the reproductive health of women 40 years and older after embolization of the uterine arteries, it was found that this method of treatment of symptomatic uterine fibroids leads to a decrease in the duration and heaviness of menstruation but increases the risk of an ovarian reserve decrease.

Evaluation of the effectiveness of a new surgical correction method for combined pelvic organ prolapse in women of reproductive age: A prospective non-randomized study
Danilina O.A., Volkov V.G.
Abstract

Aim. To evaluate the effectiveness of combined pelvic organ prolapse correction using the proposed modification of laparoscopic promontofixation of the uterus and vaginal walls using a mesh graft in women of reproductive age.

Materials and methods. A prospective non-randomized study included 41 women of reproductive age (up to 49 years) with grade II–IV symptomatic combined pelvic organ prolapse. The main group (n=19) included women who underwent surgery using the proposed original method (invention patent No. RU2795649C1 dated October 27, 2022), the control group (n=22) included women who underwent conventional laparoscopic promontofixation of the uterus and vaginal walls and vaginal plasty with local tissues. The duration of surgery, intraoperative blood loss, anatomical result, effect on symptoms and sexual function were assessed using the Pelvic Floor Distress Inventory (PFDI-20), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12).

Results. The duration of surgery and intraoperative blood loss were significantly lower in the main group (p=0.043 and p<0.001, respectively). Anatomical success was achieved in both groups and persisted throughout the follow-up period (without statistically significant differences). Analysis of the PFDI-20 questionnaire responses showed a significant improvement in both groups with no statistically significant differences. Analysis of the PISQ-12 questionnaire data showed a significant improvement in the quality of sexual life in both groups; however, after a year of follow-up, patients of the main group had a significantly better quality of sexual life (p<0.05).

Conclusion. The surgical correction of combined pelvic organ prolapse using the proposed method demonstrated a good anatomical result, a decrease in intraoperative blood loss and duration of surgery, as well as an improvement in sexual function in women of reproductive age.

Polymorphic variants of the PPP1R21 gene associated with the level of sex hormone-binding globulin and the risk of various stages of breast cancer
Pasenov K.N., Ponomarenko I.V., Churnosov M.I.
Abstract

Aim. To assess the relationship of polymorphic gene variants associated with the level of sex hormone-binding globulin (SHBG) according to genome-wide association studies (GWAS) with the risk of stage I–II and stage III-IV breast cancer.

Materials and methods. A comparative genetic analysis was carried out on samples of patients with breast cancer: 254 patients with stages I–II and 91 with stages III–IV, and 1140 females of the control group. The paper considers 4 single nucleotide substitutions associated with the level of circulating SHBG according to GWAS: g.107546375A>G PRMT6 (rs17496332), g.27519736T>C GCKR (rs780093), g.48419260T>C PPP1R21 (rs10454142), g.98364050T>A BAIAP2L1 (rs3779195).

Results. Differences in the involvement of polymorphic variants of SHBG candidate genes in the development of stages I–II and III–IV breast cancer were revealed. The rs10454142 T>C polymorphic variant in the PPP1R21 gene is associated with the risk of stage I–II breast cancer: women with an allelic variant of this locus have a higher risk of early-stage disease (T/T vs. T/C vs. C/C, odds ratio 1.35, 95% confidence interval 1.05-1.75; p=0.021; ppermutat=0.027). Also, an increase in the number of C alleles in the female genotype increased the risk of stage I–II breast cancer by 17–18% per allele. There were no associations of polymorphic variants of SHBG candidate genes with the risk of severe disease (stage III–IV). The single nucleotide substitution rs10454142 T>C in the PPP1R21 gene and the single nucleotide polymorphisms strongly linked to it are functionally significant (located in the regions of enhancers and promoters) in the epithelial and myoepithelial cells of the mammary gland and liver, affect the level of genome methylation, and are associated with the level of GTF2A1L gene expression.

Adherence to endocrine therapy with tamoxifen and satisfaction with follow-up of women with breast cancer by a gynecologist: A survey study
Golubenko E.O., Savelyeva M.I., Korennaya V.V.
Abstract

Background. Side effects of endocrine therapy with tamoxifen (TAM) reduce the quality of life of patients with breast cancer (BC) and adversely affect treatment compliance. Against the background of treatment of BC with TAM, the risk of developing endometrial hyperplasia (EH) increases. At the moment, algorithms for monitoring patients receiving TAM by an obstetrician-gynecologist have not been developed and approved. There are also divergent opinions of experts regarding the diagnosis and management of patients in the detection of EH. This article presents the results of the final stage of the study in 2017–2022 – a survey study. The purpose of this study was to assess adherence to endocrine therapy and satisfaction with observation by a gynecologist of women with BC after 5 years of observation and their relationship with the identified early associated polymorphisms of the CYP2D6, CYP3A5, CYP2C9 and ABCB1 genes.

Materials and methods. 54 patients with BC, out of 120 who had previously passed the first pharmacogenetic stage of the study, were interviewed with specially designed questionnaire. Due to the small sample size, delta percentages (∆%) were used in each comparison group with a difference threshold of 5%. To assess associations with the studied genetic polymorphisms, previously obtained significant associations of adverse drug reactions with pharmacogenetics in the same patients were used.

Results. The prevalence of all adverse drug reactions (ADRs), with the exception of EH, was higher in the group of patients who canceled TAM. Over 5 years of follow-up, 57.4% of patients were regularly observed by an obstetrician-gynecologist, 42.59% of patients visited a gynecologist less than once a year. Of all the respondents, 53.7% of patients are satisfied with the regularity and quality of dispensary observation by an oncologist, 33.33% of patients are satisfied with the regularity and quality of dispensary observation by an obstetrician-gynecologist. All studied ADRs (EH, hot flashes, asthenia, bone pain and dyspepsia) associated with various genetic polymorphisms, prevailed in the group of patients who stopped taking TAM due to drug intolerance (∆%: 25.72, 6.97, 4.81, 6.97 and 24.52 respectively) compared with the TAM-group.

Conclusion. The results obtained confirm the role of the studied genetic polymorphisms in the development of ADRs of TAM, but only systemic (hot flashes, asthenia, bone pain and dyspepsia). With regard to endometrial hyperplasia, no significant differences were obtained, which requires more extensive studies.
