Effective treatment of heavy and/or prolonged menstrual bleeding without organic cause: pooled analysis of two multinational, randomised, double-blind, placebo-controlled trials of oestradiol valerate and dienogest.

ABSTRACT: OBJECTIVES: To evaluate the efficacy of oestradiol valerate/dienogest (E2V/DNG) for the treatment of heavy and/or prolonged menstrual bleeding without organic pathology based on the analysis of data from two identically designed double-blind, randomised studies. METHODS: Women aged ? 18 years with heavy and/or prolonged menstrual bleeding were randomised to E2V/DNG (n = 269) or placebo (n = 152) for 196 days. Objective changes in menstrual blood loss (MBL) volume were assessed using the alkaline haematin method. RESULTS: After six months of treatment, median MBL decreased by 88% with E2V/DNG compared with 24% with placebo. The greatest reduction was achieved at the first withdrawal bleed after treatment initiation and it was sustained with no loss of effect throughout treatment. CONCLUSION: E2V/DNG was more effective than placebo in reducing MBL in women with heavy and/or prolonged menstrual bleeding without organic pathology. The reduction was largely achieved as early as the first withdrawal bleed, with further gradual improvement throughout treatment.

Project description:BackgroundHeavy menstrual bleeding (HMB) is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce prostaglandin levels, which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea.ObjectivesTo determine the effectiveness, safety and tolerability of NSAIDs in achieving a reduction in menstrual blood loss (MBL) in women of reproductive years with HMB.Search methodsWe searched, in April 2019, the Cochrane Gynaecology and Fertility specialised register, Cochrane Central Register of Studies Online (CENTRAL CRSO), MEDLINE, Embase, PsycINFO, the clinical trial registries and reference lists of articles.Selection criteriaThe inclusion criteria were randomised comparisons of individual NSAIDs or combined with other medical therapy with each other, placebo or other medical treatments in women with regular heavy periods measured either objectively or subjectively and with no pathological or iatrogenic (treatment-induced) causes for their HMB.Data collection and analysisWe identified 19 randomised controlled trials (RCTs) (759 women) that fulfilled the inclusion criteria for this review and two review authors independently extracted data. We estimated odds ratios (ORs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes from the data of nine trials. We described in data tables the results of the remaining seven cross-over trials with data unsuitable for pooling, one trial with skewed data, and one trial with missing variances. One trial had no data available for analysis.Main resultsAs a group, NSAIDs were more effective than placebo at reducing HMB but less effective than tranexamic acid, danazol or the levonorgestrel-releasing intrauterine system (LNG IUS). Treatment with danazol caused a shorter duration of menstruation and more adverse events than NSAIDs, but this did not appear to affect the acceptability of treatment, based on trials from 1980 to 1990. However, currently danazol is not a usual or recommended treatment for HMB. There was no clear evidence of difference between NSAIDs and the other treatments (oral luteal progestogen, ethamsylate, an older progesterone-releasing intrauterine system and the oral contraceptive pill (OCP), but most studies were underpowered. There was no evidence of a difference between the individual NSAIDs (naproxen and mefenamic acid) in reducing HMB. The evidence quality ranged from low to moderate, the main limitations being risk of bias and imprecision.Authors' conclusionsNSAIDs reduce HMB when compared with placebo, but are less effective than tranexamic acid, danazol or LNG IUS. However, adverse events are more severe with danazol therapy. In the limited number of small studies suitable for evaluation, there was no clear evidence of a difference in efficacy between NSAIDs and other medical treatments such as oral luteal progestogen, ethamsylate, OCP or the older progesterone-releasing intrauterine system.

Project description:ObjectiveTo determine the relative effectiveness of second generation ablation techniques in the treatment of heavy menstrual bleeding.DesignNetwork meta-analysis on the primary outcome measures of amenorrhoea, heavy bleeding, and patients' dissatisfaction with treatment.Data sourcesNineteen randomised controlled trials (involving 3287 women) were identified through electronic searches of the Cochrane Library, Medline, Embase and PsycINFO databases from inception to April 2011. The reference lists of known relevant articles were searched for further articles. Two reviewers independently selected articles without language restrictions.Eligibility criteria for selecting studiesRandomised controlled trials involving second generation endometrial destruction techniques for women with heavy menstrual bleeding unresponsive to medical treatment.ResultsOf the three most commonly used techniques, network meta-analysis showed that bipolar radiofrequency and microwave ablation resulted in higher rates of amenorrhoea than thermal balloon ablation at around 12 months (odds ratio 2.51, 95% confidence interval 1.53 to 4.12, P<0.001; and 1.66, 1.01 to 2.71, P=0.05, respectively), but there was no evidence of a convincing difference between the three techniques in the number of women dissatisfied with treatment or still experiencing heavy bleeding. Compared with bipolar radio frequency and microwave devices, an increased number of women still experienced heavy bleeding after free fluid ablation (2.19, 1.07 to 4.50, P=0.03; and 2.91, 1.23 to 6.88, P=0.02, respectively). Compared with radio frequency ablation, free fluid ablation was associated with reduced rates of amenorrhoea (0.36, 0.19 to 0.67, P=0.004) and increased rates of dissatisfaction (4.79, 1.07 to 21.5, P=0.04). Of the less commonly used devices, endometrial laser intrauterine thermotherapy was associated with increased rates of amenorrhoea compared with all the other devices, while cryoablation led to a reduced rate compared with bipolar radio frequency and microwave.ConclusionsBipolar radio frequency and microwave ablative devices are more effective than thermal balloon and free fluid ablation in the treatment of heavy menstrual bleeding with second generation endometrial ablation devices.

Project description:BackgroundThe symptom of heavy menstrual bleeding (HMB) diminishes quality-of-life for many mid-age women and imposes substantial societal burden. We investigated our hypothesis that HMB reflects impaired endometrial vasoconstriction due to endometrial glucocorticoid deficiency. Does reversing this deficiency, by short-term luteal-phase treatment with exogenous glucocorticoid (dexamethasone), ameliorate HMB?MethodsIn our Bayesian response-adaptive parallel-group placebo-controlled randomised trial, five pre-planned interim analyses used primary outcome data to adjust randomisation probabilities to favour doses providing most dose-response information. Participants with HMB, recruited from Lothian (Scotland) NHS clinics and via community invitations/advertisements, were aged over 18 years; reported regular 21-42 day menstrual cycles; and had measured menstrual blood loss (MBL) averaging ≥ 50 mL over two screening periods. Identically encapsulated placebo, or one of six Dexamethasone doses (0·2 mg, 0·4 mg, 0·5 mg, 0·6 mg, 0·75 mg, 0·9 mg), were taken orally twice-daily over five days in the mid-luteal phase of three menstrual cycles. Participants, investigators, and those measuring outcomes were masked to group assignment. Primary outcome, change in average MBL from screening to 'treatment', was analysed by allocated treatment, for all with data.Trial registrationClinicalTrials.gov NCT01769820; EudractCT 2012-003,405-98 FINDINGS: Recruitment lasted 29/01/2014 to 25/09/2017; 176 were screened, 107 randomised and 97 provided primary outcome data (n = 24,5,9,21,8,14,16 in the seven arms, placebo to 1·8 mg total daily active dose). In Bayesian normal dynamic linear modelling, 1·8 mg dexamethasone daily showed a 25 mL greater reduction in MBL from screening, than placebo (95% credible interval 1 to 49 mL), and probability 0·98 of benefit over placebo. Adverse events were reported by 75% (58/77) receiving dexamethasone, 58% (15/26) taking placebo. Three serious adverse events occurred, two during screening, one in a placebo participant. No woman withdrew due to adverse effects.InterpretationOur adaptive trial in HMB showed that dexamethasone 1·8 mg daily reduced menstrual blood loss. The role of dexamethasone in HMB management deserves further investigation.FundingUK MRC DCS/DPFS grant MR/J003611/1.
