Hormone therapy for premature ovarian insufficiency patients with malignant hematologic diseases

OBJECTIVES

The current usage of hormone therapy (HT) among perimenopausal women is low in China, especial in women with premature ovarian insufficiency (POI) with malignant hematologic diseases. This study investigated the efficacy and safety of HT in POI patients with malignant hematologic diseases who have received myeloablative chemotherapy and hemopoietic stem cell transplantation (HSCT).

METHODS

Patients who had POI after myeloablative chemotherapy and HSCT for malignant hematologic diseases were enrolled. Questionnaires with information about characteristics, menstrual status, sex hormone levels and menopausal symptoms were used to evaluate the relief from menopausal symptoms and safety of HT.

RESULTS

Among 130 cases, 103 (79.2%) patients had perimenopausal symptoms. The mean total Kupperman menopausal index score changed significantly from 13.50 ± 7.128 to 6.13 ± 5.97 after HT for 24 months. Among the 118 patients who received estrogen/progestin cyclic sequential therapy, 89 (75.4%) had withdrawal bleeding.

CONCLUSION

Myeloablative chemotherapy against leukemia may cause POI. HT may relieve perimenopausal symptoms after myeloablative chemotherapy and HSCT. HT was safe and no excessive recurrences or mortality were seen in the hormone-treated group for patients who survived from malignant hematologic diseases and who received HSCT.

Menopause, hormone therapy and diabetes

Over the past three decades, the prevalence of diabetes has increased four-fold. Coupled with the global obesity epidemic and aging of the world's population, a perfect metabolic storm is brewing. The influence of menopause and exogenous estrogen and progestogens must be included in this equation. In this review, criteria for diagnosing diabetes and recommendations for screening are described. The reported effects of menopause on diabetes risk in healthy women are reviewed as well as the relationship between established diabetes and the timing of menopause. The effects of menopausal hormone therapies (MHT) on glucose control in women with diabetes and the effect of MHT on diabetes risk in menopausal women without diabetes are described. Evidence-based strategies to prevent diabetes in midlife women are highlighted. The augmenting effect of diabetes on chronic health concerns of aging women, such as cardiovascular disease, osteoporosis, and cancer, along with current recommendations for screening and prevention are presented. Given the current demographics of today's world, the content of this review may apply to as many as one-third of the average practitioner's postmenopausal patient population.

Rationale and design for the Vaginal Erbium Laser Academy Study (VELAS): an international multicenter observational study on genitourinary syndrome of menopause and stress urinary incontinence

The genitourinary syndrome of menopause (GSM) and stress urinary incontinence (SUI) are common clinical challenges for women's health and quality of life. The laser treatment and particularly the vaginal erbium laser (VEL) may provide a new non-invasive treatment for both GSM and SUI. However, the estimation of the ultimate results of different laser treatments may be altered by different issues, such as patient selection, concomitant treatments, and long-term effect of vaginal laser thermotherapy. In the present paper, we present the protocol for a large multicenter study on the evaluation of the efficacy and safety of VEL for the treatment of GSM and SUI, the Vaginal Erbium Laser Academy Study (VELAS). This study will evaluate the effects of three laser applications in 1500 postmenopausal women. Subjective and objective symptoms will be evaluated prior to the first laser treatment with follow-up visits after 4 weeks from the last laser application, and subsequently after every 3 months for 1 year. Findings from the VELAS have the potential to affect clinical care practice and health decisions for millions of women world-wide for a non-hormonal treatment for GSM and a non-invasive treatment of SUI.

Impact of endo- and exogenous estrogens on heart rate variability in women: a review

Measurement of heart rate variability (HRV) is an established method to assess the activity of the autonomic nervous system. The aim of this review was to examine the link between HRV, reproductive life stages and menopausal hormone therapy. A literature review was performed using the Medline database. Based on title and abstract, 45 studies were extracted out of 261 citations screened. Due to different study designs and evaluation methods, HRV indices were not directly comparable. Qualitative comparisons in between the vast majority of studies, however, demonstrated a decrease of the vagal dominance on the heart from the follicular to the luteal cycle phase, although some studies asserted no change. The intake of oral contraceptives appeared not to alter the vagal modulation of the heart. All investigations agreed on a decline of HRV towards higher sympathetic control after menopause. Different menopausal hormone therapy approaches showed a supporting impact of estrogen on HRV in most studies. A combined therapy of estrogen and progestogens revoked this benefit. Further research is needed to demonstrate how this process might be attenuated by different menopausal hormone therapies.

Long-term health consequences of premature or early menopause and considerations for management

AIM

To review the current evidence concerning the long-term harmful effects of premature or early menopause, and to discuss some of the clinical implications.

MATERIAL AND METHODS

Narrative review of the literature.

RESULTS

Women undergoing premature or early menopause, either following bilateral salpingo-oophorectomy or because of primary ovarian insufficiency, experience the early loss of estrogen and other ovarian hormones. The long-term consequences of premature or early menopause include adverse effects on cognition, mood, cardiovascular, bone, and sexual health, as well as an increased risk of early mortality. The use of hormone therapy has been shown to lessen some, although not all of these risks. Therefore, multiple medical societies recommend providing hormone therapy at least until the natural age of menopause. It is important to individualize hormone therapy for women with early estrogen deficiency, and higher dosages may be needed to approximate physiological concentrations found in premenopausal women. It is also important to address the psychological impact of early menopause and to review the options for fertility and the potential need for contraception, if the ovaries are intact.

CONCLUSIONS

Women who undergo premature or early menopause should receive individualized hormone therapy and counseling.

Effects of estrogen therapy on postmenopausal sleep quality regardless of vasomotor symptoms: a randomized trial

OBJECTIVE

To determine the effects of estrogen therapy on objective sleep quality in insomniac postmenopausal women without severe vasomotor symptoms and/or recognized hot flushes during sleep. Study design Randomized, double-blinded, placebo-controlled trial, parallel design (ClinicalTrials.gov Identifier: NCT01501422).

METHODS

Forty insomniac postmenopausal women with no severe vasomotor symptoms and/or recognized hot flushes during sleep were randomized into 2 months' treatment with a 50-μg transdermal estradiol patch or placebo. Sleep quality was determined objectively with wrist actigraphy. Sleep efficiency, total sleep time, wake up after sleep onset and number of awakenings were compared before and after treatment. The Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) questionnaires were used for subjective sleep quality assessment before and after treatment.

RESULTS

The study showed no significant difference in sleep efficiency improvement between women having estrogen alone or placebo (median 85.7% vs. 85.2%, respectively, p = 0.71). Similarly, sleep quality scores assessed by ISI and ESS were not significantly different.

CONCLUSION

Estrogen therapy in insomniac postmenopausal women without severe vasomotor symptoms and/or recognized hot flushes during sleep was not found to improve sleep efficiency during the study period.

Effectiveness, tolerability and acceptance of an oral estradiol/levonorgestrel formulation for the treatment of menopausal complaints: a non-interventional observational study over six cycles of 28 days

BACKGROUND

Use of hormone therapy for menopausal complaints is a subject of controversy and increased uncertainty and concerns. This non-interventional study aimed to investigate a marketed oral formulation containing 1 mg estradiol and 0.04 mg levonorgestrel for continuous treatment of menopausal symptoms for approximately 6 months in women visiting gynecological practices in Germany.

METHODS

Changes in the menopause rating scale (MRS) total and sub-domain scores after three and six 28-d cycles served as primary endpoint. Skin- and hair-related complaints, quality of sexual life and subjective satisfaction with the treatment were assessed. Adverse drug reactions (ADRs), adverse events (AEs) and vaginal bleeding were evaluated.

RESULTS

MRS scores improved significantly above 5 points of clinical relevance as compared to baseline (n = 736, p < 0.0001). Skin- and hair-related symptoms abated; quality of sexual life improved. AEs were registered in 9.9% of the participants. No unexpected ADRs were reported. Bleeding episodes consistently decreased; >75% of the subjects were amenorrheic throughout the study. Medication's effectiveness and tolerability was rated very good/good by >80% of the participants, who also continued treatment.

CONCLUSION

This estradiol/low-dose levonorgestrel formulation safely alleviates menopausal symptoms in peri- and postmenopausal women with add-on benefits regarding dermatological and sexual life complaints.
