Gonadotropin-releasing hormone analog combined with a low-dose oral contraceptive to treat heavy menstrual bleeding

Variation of outcome reporting in studies of interventions for heavy menstrual bleeding: a systematic review

Background: Heavy menstrual bleeding (HMB) detrimentally effects women. It is important to be able to compare treatments and synthesise data to understand which interventions are most beneficial, however, when there is variation in outcome reporting, this is difficult. Objectives: To identify variation in reported outcomes in clinical studies of interventions for HMB. Materials and methods: Searches were performed in medical databases and trial registries, using the terms ‘heavy menstrual bleeding’, menorrhagia*, hypermenorrhoea*, HMB, “heavy period „period“, effective*, therapy*, treatment, intervention, manage* and associated MeSH terms. Two authors independently reviewed and selected citations according to pre-defined selection criteria, including both randomised and observational studies. The following data were extracted- study characteristics, methodology and quality, and all reported outcomes. Analysis considered the frequency of reporting. Results: There were 14 individual primary outcomes, however reporting was varied, resulting in 45 specific primary outcomes. There were 165 specific secondary outcomes. The most reported outcomes were menstrual blood loss and adverse events. Conclusions: A core outcome set (COS) would reduce the evident variation in reporting of outcomes in studies of HMB, allowing more complete combination and comparison of study results and preventing reporting bias. What is new? This in-depth review of past research into heavy menstrual bleeding shows that there is the need for a core outcome set for heavy menstrual bleeding.

The Menstrual Endometrium: From Physiology to Future Treatments

Abnormal uterine bleeding (AUB) is experienced by up to a third of women of reproductive age. It can cause anaemia and often results in decreased quality of life. A range of medical and surgical treatments are available but are associated with side effects and variable effectiveness. To improve the lives of those suffering from menstrual disorders, delineation of endometrial physiology is required. This allows an increased understanding of how this physiology may be disturbed, leading to uterine pathologies. In this way, more specific preventative and therapeutic strategies may be developed to personalise management of this common symptom. In this review, the impact of AUB globally is outlined, alongside the urgent clinical need for improved medical treatments. Current knowledge of endometrial physiology at menstruation is discussed, focusing on endocrine regulation of menstruation and local endometrial inflammation, tissue breakdown, hypoxia and endometrial repair. The contribution of the specialised endometrial vasculature and coagulation system during menstruation is highlighted. What is known regarding aberrations in endometrial physiology that result in AUB is discussed, with a focus on endometrial disorders (AUB-E) and adenomyosis (AUB-A). Gaps in existing knowledge and areas for future research are signposted throughout, with a focus on potential translational benefits for those experiencing abnormal uterine bleeding. Personalisation of treatment strategies for menstrual disorders is then examined, considering genetic, environmental and demographic characteristics of individuals to optimise their clinical management. Finally, an ideal model of future management of AUB is proposed. This would involve targeted diagnosis of specific endometrial aberrations in individuals, in the context of holistic medicine and with due consideration of personal circumstances and preferences.

Gonadotropin-Releasing Hormone Agonists Are Effective in Long-term Treatment of Women with Abnormal Uterine Bleeding and Anticoagulant Therapy: Report of 3 Cases and Review of the Literature

Purpose of Review

To evaluate the efficacy of gonadotropin-releasing hormone agonist (GnRHa) in women with abnormal uterine bleeding (AUB) on anticoagulant therapy.

Recent Findings

Prospective observational case series (Canadian Task Force Classification II-3) at University-affiliated teaching hospital. From January 2002 through December 2019, three premenopausal women on warfarin therapy were identified from our clinical practice. After clinical assessment, including Papanicolaou smear, endometrial biopsy, and pelvic sonography, a GnRHa was used to treat their AUB. Two women were receiving warfarin therapy (5–7 mg/day) for previous venous thromboembolism and one for mechanical heart valve replacement associated with Marfan’s syndrome. All patients had additional comorbid conditions and were at high risk for traditional medical or surgical therapies. After treatment with GnRHa, all women reported menstrual reduction at 3 months and remained amenorrheic for 2 to 11 years, two of whom reached menopause.

Summary

In properly assessed and selected premenopausal women with AUB receiving anticoagulant therapy and at high risk for traditional therapies, long-term GnRHa was an effective treatment in 3 patients.

Heavy menstrual bleeding diagnosis and medical management

Heavy menstrual bleeding (HMB) is a common gynecological problem that has a significant impact on a woman’s quality of life and the activities of daily living. Due to the difficulty in accurately describing menstrual bleeding abnormalities using older terminology, the PALM-COEIN classification system of the Federation Internationale de Gynecologie et d’Obstetrique was proposed to describe and identify the etiology of abnormal endometrial bleeding. As there is no single pathway that is associated with HMB, there are several therapeutic interventions involving different molecular pathways to reduce HMB. This article will highlight the current evidence as it relates to the etiology of HMB as well as medical modalities of treatment.

The medical management of abnormal uterine bleeding in reproductive-aged women

In the treatment of women with abnormal uterine bleeding, once a thorough history, physical examination, and indicated imaging studies are performed and all significant structural causes are excluded, medical management is the first-line approach. Determining the acuity of the bleeding, the patient's medical history, assessing risk factors, and establishing a diagnosis will individualize their medical regimen. In acute abnormal uterine bleeding with a normal uterus, parenteral estrogen, a multidose combined oral contraceptive regimen, a multidose progestin-only regimen, and tranexamic acid are all viable options, given the appropriate clinical scenario. Heavy menstrual bleeding can be treated with a levonorgestrel-releasing intrauterine system, combined oral contraceptives, continuous oral progestins, and tranexamic acid with high efficacy. Nonsteroidal antiinflammatory drugs may be utilized with hormonal methods and tranexamic acid to decrease menstrual bleeding. Gonadotropin-releasing hormone agonists are indicated in patients with leiomyoma and abnormal uterine bleeding in preparation for surgical interventions. In women with inherited bleeding disorders all hormonal methods as well as tranexamic acid can be used to treat abnormal uterine bleeding. Women on anticoagulation therapy should consider using progestin-only methods as well as a gonadotropin-releasing hormone agonist to treat their heavy menstrual bleeding. Given these myriad options for medical treatment of abnormal uterine bleeding, many patients may avoid surgical intervention.

Hormonal contraception as treatment for heavy menstrual bleeding: a systematic review

A systematic review to compare the effectiveness of contraceptives to treat heavy menstrual bleeding (HMB). PubMed was searched for studies using hormonal contraceptive methods to treat HMB. Two reviewers screened 734 citations and extracted eligible trials based on rigid inclusion and exclusion criteria. Fourteen articles met inclusion criteria. The evidence was good to poor quality and suggested that all contraceptives tested were effective in the treatment of HMB, but the levonorgestrel intrauterine system was the most effective method. Hormonal contraceptives effectively treat HMB. The levonorgestel intrauterine system is the superior method.

Nonsurgical management of heavy menstrual bleeding: a systematic review

OBJECTIVE

To compare the effectiveness of nonsurgical abnormal uterine bleeding treatments for bleeding control, quality of life (QOL), pain, sexual health, patient satisfaction, additional treatments needed, and adverse events.

DATA SOURCES

MEDLINE, Cochrane databases, and Clinicaltrials.gov were searched from inception to May 2012. We included randomized controlled trials of nonsurgical treatments for abnormal uterine bleeding presumed secondary to endometrial dysfunction and abnormal uterine bleeding presumed secondary to ovulatory dysfunction. Interventions included the levonorgestrel intrauterine system, combined oral contraceptive pills (OCPs), progestins, nonsteroidal anti-inflammatory drugs (NSAIDs), and antifibrinolytics. Gonadotropin-releasing hormone agonists, danazol, and placebo were allowed as comparators.

METHODS OF STUDY SELECTION

Two reviewers independently screened 5,848 citations and extracted eligible trials. Studies were assessed for quality and strength of evidence.

TABULATION, INTEGRATION, AND RESULTS

Twenty-six articles met inclusion criteria. For reduction of menstrual bleeding in women with abnormal uterine bleeding presumed secondary to endometrial dysfunction, the levonorgestrel intrauterine system (71-95% reduction), combined OCPs (35-69% reduction), extended cycle oral progestins (87% reduction), tranexamic acid (26-54% reduction), and NSAIDs (10-52% reduction) were all effective treatments. The levonorgestrel intrauterine system, combined OCPs, and antifibrinolytics were all superior to luteal-phase progestins (20% increase in bleeding to 67% reduction). The levonorgestrel intrauterine system was superior to combined OCPs and NSAIDs. Antifibrinolytics were superior to NSAIDs for menstrual bleeding reduction. Data were limited on other important outcomes such as QOL for women with abnormal uterine bleeding presumed secondary to endometrial dysfunction and for all outcomes for women with abnormal uterine bleeding presumed secondary to ovulatory dysfunction.

CONCLUSION

For the reduction in mean blood loss in women with heavy menstrual bleeding presumed secondary to abnormal uterine bleeding presumed secondary to endometrial dysfunction, we recommend the use of the levonorgestrel intrauterine system over OCPs, luteal-phase progestins, and NSAIDs. For other outcomes (QOL, pain, sexual health, patient satisfaction, additional treatments needed, and adverse events) and for treatment of abnormal uterine bleeding presumed secondary to ovulatory dysfunction, we were unable to make recommendations based on the limited available data.

Pharmacological therapy for abnormal uterine bleeding

Pharmacological therapies for the treatment of abnormal uterine bleeding are effective and generally well tolerated. This review presents an evidence-based approach to medical therapy. Selection depends on the etiology and amount of bleeding, need for contraception or preservation of fertility, perimenopause status, and medication efficacy and adverse effects.Available nonhormonal agents include nonsteroidal anti-inflammatory agents, which reduce bleeding by 25% to 35% and improve dysmenorrhea through reduced prostaglandin levels; tranexamic acid, which inhibits plasminogen activator with a 40% to 60% reduction in menstrual blood loss; and intranasal desmopressin, which is an antifibrinolytic for women with an underlying bleeding disorder (eg, von Willebrand disease).Hormonal regimens cause the inhibition of endometrial growth. Cyclic progestogen therapy for 21 days results in a significant reduction in menstrual blood loss. Limited data suggest that oral contraceptives reduce menstrual blood loss by 40% to 50% with decreased breast tenderness and dysmenorrhea and a reduction in risk of uterine and ovarian cancer. The progestin-releasing intrauterine devices are effective up to 97% by 6 months and provide relief of dysmenorrhea and contraception. Long-acting progestogen injections produce amenorrhea and provide contraception but are associated with irregular spotting and reversible bone loss. Danazol leads to endometrial atrophy with a reduced menstrual loss; androgenic adverse effects may be lessened with lower doses or vaginal use. Gonadotrophin agonists lead to ovarian suppression and are used to shrink fibroids or the endometrium preoperatively but are limited by hypoestrogenic adverse events. Emergency use of parenteral conjugated estrogens has a 70% chance of stopping abnormal bleeding but an increased risk of thrombosis.
