RESUMEN
The genitourinary syndrome of menopause (GSM) affects up to 84% of postmenopausal women and may significantly reduce the quality of life in some. For symptom relief, there are several non-hormonal and hormonal vaginal products available. In Europe, vaginal estriol (E3) is the most frequently chosen estrogen for GSM treatment. The aim of this systematic review was to assess the impact of vaginal E3 on serum sex hormone levels, an outcome that has been previously used to assess safety in similar products. In our review, we did not find any alterations in serum estrone, estradiol, testosterone, progesterone and sex hormone binding globulin levels after vaginal E3 application. In contrast, some studies showed a minimal and transient decrease in serum gonadotropin levels, which however remained within the postmenopausal range. Similarly, only a few studies reported a minimal and transient increase of serum E3 levels, with the rest reporting no changes. The lack of clinically relevant long-term changes in serum sex hormone levels supports the current literature providing evidence about the safety of vaginal E3 products.

OBJECTIVE: To quantitate the changes in stress urinary incontinence (SUI) outcome measures after 12 weeks of vaginal estriol cream in women with stress incontinence. METHODS: A prospective multicentre observational study conducted in tertiary urogynaecology centers. Postmenopausal women with pure SUI or stress predominant mixed urinary incontinence (MUI), not receiving any other treatment for their incontinence were given written instructions regarding digital application of a standard dose of vaginal estriol cream. Outcomes were measured at baseline and 12 weeks. The primary objective outcome was vaginal pH. The primary subjective outcome was the stress domain of the Urogenital Distress Inventory-6 (UDI-6). The secondary objective outcome used was the erect cough stress test. Two quality of life questionnaires and two patient reported outcomes were also included. RESULTS: The 46 postmenopausal recruits had a median age of 62.1 interquartile range (IQR 56.2-65.4). At follow up, the primary subjective outcome SUI domain [UDI-6] significantly improved from 83.3 (IQR 50-100) to 33.3 (33.3-66.7, p ≤ 0.001) as did vaginal pH [from 5.1 (4.9-5.9) to 4.9 (4.6-5.0] p ≤ 0.001; 18/43 patients (42%) were dry on cough stress test. CONCLUSIONS: Twelve weeks of vaginal estriol cream significantly reduced symptoms of stress urinary incontinence in this sample of postmenopausal women.

AIMS: To quantify estriol serum concentrations in "new" and "chronic users" of topical estriol cream using quantitative liquid chromatography tandem mass spectrometry. METHODS: In this singlecentre prospective observational study, postmenopausal women with urogynaecological complaints were enrolled: 40 had not used topical estriol previously ("new users") and 50 had been applying estriol cream for more than 12 weeks ("chronic users"). In "new users," serum estriol levels were measured at baseline and after 12 weeks use. Estriol cream 1 mg/g was used daily for 3 weeks, then twice weekly with applicator (group 1A) or digitally (group 1B) or three times per week digitally (group 1C). "Chronic users" applied the cream twice (n = 7) or three (n = 43) times per week. Serum samples were taken in the morning after using cream the previous night. The main outcome measures were estriol serum concentrations in "new" and "chronic users" of estriol cream. RESULTS: Baseline serum estriol concentrations were less than 5 pmol/L in all 40 "new users." At 12 weeks, the 12-hour serum estriol levels ranged from less than 5 to 494 pmol/L (median 22.8; Interquartile range [IQR] 9.2-108.5). Seven "new users" had levels more than 100 pmol/L. Most of the 50 "chronic users" also had 12-hour levels less than 100 pmol/L (median 15.1 pmol/L [IQR 2.7-33.9]: three had levels more than 100 pmol/L. CONCLUSIONS: This study reports serum estriol concentrations in a large number of "new" and "chronic users" of vaginal estriol cream, employing a novel highly sensitive and specific technique. Overall, the results are reassuring: 87% had 12-hour estriol levels less than 100 pmol/L.

In recent years, a vast quantity of clinical data has been accumulated on the pathophysiology of symptomatic vulvovaginal atrophy (VVA)/genitourinary syndrome of menopause (GSM) in peri- and postmenopausal women and on the treatment options for these conditions. Guidelines from several societies have recently been updated in favor of VVA/GSM vaginal therapy with the lowest possible doses of estrogens. The combination of a vaginal ultra-low dose of 0.03 mg of estriol (E3) and lyophilized, viable Lactobacillus acidophilus KS400 (0.03 mg-E3/L) is a unique product with a dual mechanism of action supporting not only the proliferation and maturation of the vaginal epithelium, but also restoration of the lactobacillary microflora. It has been demonstrated efficiently to establish and maintain a healthy vaginal ecosystem. Use of this combination considerably improves the clinical signs and symptoms as well as the quality of life of menopausal women suffering from vaginal atrophy. This combination therapy is well tolerated with a low overall incidence of side-effects and negligible estriol absorption. Based on recent scientific evidence and current treatment guidelines, the 0.03 mg-E3/L combination could be considered one of the options for the treatment of symptomatic vaginal atrophy in aging menopausal women.

Atrophic vaginitis represents a major barrier to compliance with aromatase inhibitor (AI) therapy in breast cancer (BC) survivors. While local estrogen therapy is effective for postmenopausal vaginal dryness, the efficacy of such therapies has not been evaluated systematically in hormone receptor-positive (HR+) BC patients on AI therapy. Furthermore, the potential risk of breast cancer recurrence with vaginal estrogen therapy represents a long-term safety concern for the patients with HR + BC. Unfortunately, there is no standardized assay to measure very low concentrations of estradiol (E2) in these women being treated with AI therapy. This makes it difficult to evaluate even indirectly the potential risk of BC recurrence with vaginal estrogen therapy in HR + BC patients on AI therapy. In this review, we describe available assays to measure very low concentrations of E2, discuss the Food and Drug Administration-approved vaginal estrogen products on the market, and summarize published and ongoing clinical trials evaluating the safety and efficacy of vaginal estrogen in HR + BC patients on AI therapy. In the absence of any randomized controlled clinical trials, this review serves as a summary of available clinical data and ongoing studies to aid clinicians in selecting the best available option for their patients.

OBJECTIVE: We investigated the effect of a combination of vaginal ultra-low-dose estriol with lactobacilli on the sexual functioning domain of quality of life during the treatment of breast cancer survivors on an aromatase inhibitor with vaginal atrophy. SUBJECTS AND METHODS: This was an open-label, bicentric, exploratory, clinical study in 16 postmenopausal breast cancer survivors on aromatase inhibitors suffering from vaginal atrophy-induced sexual disorders. Atrophy symptoms were assessed by scoring with an 11-point estimation scale (0 = not at all, 10 = worst imaginable feeling). Sexuality parameters of quality of life and medication adherence were recorded in a patient's diary and in the Female Somatic Sexual Experience Instrument (FSSEI) questionnaire. Patients underwent an initial treatment for 4 weeks (one vaginal tablet of Gynoflor(®) containing 0.03 mg estriol daily), followed by maintenance therapy (three vaginal Gynoflor(®) tablets weekly) for 8 weeks. RESULTS: Vaginal dryness continuously improved from a median score of 8 at entry to a score of 4 at the end of initial therapy, and a median score of 2 at the end of maintenance therapy. Normal sexual activity before breast cancer diagnosis was reported by 14 women (88%). At study entry, only three women (19%) were sexually active. At the end of the Gynoflor(®) regimen, ten women (63%) reported sexual activity, of which seven (44%) reported sexual intercourse. The FSSEI demonstrated a non-significant trend of improvement of parameters related to sexuality. CONCLUSIONS: Local vaginal therapy with Gynoflor(®) in breast cancer survivors on aromatase inhibitors reporting atrophic vaginitis could be considered as a useful treatment for the quality of sexual life.
