Some women may be reluctant to use vaginal estradiol preparations because of the concern for developing breast cancer and endometrial hyperplasia. Therefore, it is necessary to compare the therapeutic effectiveness of alternative vaginal drugs, such as promestriene, an estrogen agonist, and sodium hyaluronate (NaH), a nonhormonal, water-based agent. Methods: Ninety-one postmenopausal women diagnosed with symptomatic VA were divided into three groups and treated for 12 weeks; 30 women with vaginal estradiol (VE), 30 women with promestriene, and 31 women with NaH. Composite scoring, vaginal maturation index (VMI), pH, frequency of sexual activity, serum hormone levels, and endometrial thickness were evaluated VA before and after treatment. Results: In the comparison of VA examination findings composite scoring, VMI, and vaginal pH values, three different drugs were found to be effective in the treatment (P < 0.05). The VMI following VE treatment was significantly higher than that after NaH treatment (P = 0.031), whereas the promestriene group had a more positive change than the others in terms of increase in after treatment composite scoring and sexual activity frequency (P = 0.031, P = 0.020). There were no differences between the groups in terms of pre and after treatment serum E2 levels and endometrial thickness. Conclusions: Based on these findings, we can conclude that the use of promestriene or NaH can prove to be as effective and well tolerated as vaginal estradiol in the symptomatic treatment of vaginal atrophy.

  • Genitourinary Syndrome of Menopause in Breast Cancer Survivors: Are We Facing New and Safe Hopes?
    Review Genitourinary Syndrome of Menopause in Breast Cancer Survivors: Are We Facing New and Safe Hopes? Nicoletta Biglia,1 Valentina E. Bounous,1 Luca G. Sgro,1 Marta D’Alonzo,1 Silvia Pecchio,1 Rossella E. Nappi2 Abstract Breast cancer survivors (BCSs) often suffer from menopausal symptoms induced by systemic treatments, with a consequent negative effect on quality of life. Since the introduction of aromatase inhibitors as the standard therapy for hormone-dependent tumors, genitourinary syndrome of menopause (GSM) has become a main problem for BCSs. This new terminology refers to the wide range of vaginal and urinary symptoms related to menopause, which can be relieved by estrogen therapy. Unfortunately, systemic hormone therapy is contraindicated for BCSs and also vaginal estrogens at standard dosage might influence the risk of recurrence because they cause a significant increase of circulating estrogens. Nonhormonal vaginal moisturizers or lubricants are the first choice for BCSs but only have limited and short-term efficacy. New strategies of management of GSM are now available, including: (1) low-dose or ultra low-dose vaginal estrogens; (2) oral selective estrogen receptor modulators (ospemifene); (3) androgen therapy; (4) physical treatment with vaginal laser; and (5) psychosocial interventions. In this review we discuss and analyze these different options. Clinical Breast Cancer, Vol. -, No. -, --- ª 2015 Elsevier Inc. All rights reserved.

  • Long-Term Menopausal Treatment Using an Ultra-High Dosage of Tibolone in an Elderly Chinese Patient – Case Report
    Long-term menopausal treatment using an ultra-high dosage of tibolone in an elderly Chinese patient – Case report Lingyan Zhang 1, Xiangyan Ruan 1,2*, Muqing Gu 1, Alfred O. Mueck 1,2 1 Department of Gynecological Endocrinology, Beijing Obstetrics and Gynecology Hospital, Capital Medical University, Beijing 100026, China; 2 Department of Women’s Health, University Women’s Hospital and Research Centre for Women’s Health, University of Tuebingen, Tuebingen D-72076, Germany) ABSTRACT This report describes the special case of a Chinese woman with severe vasomotor symptoms (VSMs), depressed mood, low energy and genitourinary syndrome of menopause, including problems of sexual dysfunction, who was treated with tibolone. The aim of the report is to highlight the value of individualizing menopausal hormone therapy (MHT) type and dosage. Since 16 years of previous treatment with various other forms of MHT had not provided satisfactory efficacy in this patient, at the age of 71 years she was prescribed tibolone, starting at the usual lowest dosage of 1.25 mg/day. We gradually had to increase the dosage of tibolone up to 7.5 mg/day, which is three-fold the recommended maximum dosage. We added three-monthly sequential dydrogesterone to reduce the risk of breakthrough bleeding and the risk of endometrial cancer. To date, we have observed no side effects and no remarkable abnormal laboratory assessments, with the exception of increased thyroid-stimulating hormone, which we monitor six-monthly. Even though the patient has been informed about potential risks, such as increased risks of stroke, breast cancer and endometrial cancer, as described in the discussion, she has now been willing to accept this ultra-high dosage for seven years, and wishes to continue with this treatment.

[Epub ahead of print] Fractional CO2 laser versus promestriene and lubricant in genitourinary syndrome of menopause: a randomized clinical trial. Politano CA1, Costa-Paiva L, Aguiar LB, Machado HC, Baccaro LF. OBJECTIVE: The aim of this study was to compare the effects of fractional CO2 laser therapy, promestriene, and vaginal lubricants on genitourinary syndrome treatment and sexual function in postmenopausal women. METHODS: We performed a randomized clinical trial including 72 postmenopausal women over the age of 50 years. The women were randomized into three intervention groups to receive one of the following treatments: three sessions of intravaginal fractional CO2 laser therapy; 10 mg of intravaginal promestriene cream 3 times a week; and vaginal lubricant application alone. Vaginal maturation, Vaginal Health Index (VHI) score, and Female Sexual Function Index (FSFI) were evaluated at baseline and after 14 weeks of therapy. RESULTS: We observed an improvement in the vaginal elasticity, volume, moisture, and pH in the CO2 laser and promestriene groups. The VHI score at 14 weeks was higher in the CO2 laser group (mean score 18.68) than in the promestriene (15.11) and lubricant (10.44) groups (P < 0.001). Regarding vaginal maturation, basal cells were reduced and superficial cells were increased after treatment. This improvement was more significant in the CO2 laser group (P <0.001). The FSFI score only showed improvement in the desire and lubrication domains in the CO2 laser group.

Results: We present a novel method for systematic analyses of the underlying features characteristic of drug-protein interaction networks, which we call “drug-protein interaction signatures” from the integration of large-scale heterogeneous data of drugs and proteins. We develop a new efficient algorithm for extracting informative drug- protein interaction signatures from the integration of large-scale heterogeneous data of drugs and proteins, which is made possible by space-efficient representations for fingerprints of drug-protein pairs and sparsity-induced classifiers. Conclusions: Our method infers a set of drug-protein interaction signatures consisting of the associations between drug chemical substructures, adverse drug reactions, protein domains, biological pathways, and pathway modules. We argue the these signatures are biologically meaningful and useful for predicting unknown drug-protein interactions and are expected to contribute to rational drug design.
