Progesterone or progestogen-releasing intrauterine systems for heavy menstrual bleeding

Medroxyprogesterone Acetate for Abnormal Uterine Bleeding Due to Ovulatory Dysfunction: The Effect of 2 Different-Duration Regimens

Background

Abnormal uterine bleeding (AUB) lowers the quality of life of women. This study attempted to determine which treatment protocol of medroxyprogesterone acetate (MPA), 15 vs 10 day-administration in a luteal phase, provides better outcomes in women with ovulatory dysfunction-related AUB (AUB-O).

Material/Methods

The study included a total of 52 patients with AUB-O: Women in Group A were given MPA between days 11 and 25 of the menstrual cycle (15-day protocol), whereas women in Group B were given MPA between days 16 and 25 (10-day protocol). Outcomes were compared between the 2 groups.

Results

Women in group B, compared with those in group A, more often showed regular menstrual cycles and decrement of AUB. In group B, 3 cycles of treatment were sufficient to achieve AUB-stop (p<0.05). Post-treatment hemogram parameters and surgical treatment requirements were not different between the 2 groups.

Conclusions

In the second half of the cycle/predicted luteal phase, 10-day cyclic use of MPA (the group B) better regulated the menstrual cycle and more frequently stopped AUB-O.

Contemporary treatment utilization among women diagnosed with symptomatic uterine fibroids in the United States

BACKGROUND

This study evaluated treatment patterns among women diagnosed with symptomatic uterine fibroids (UF) in the United States. Data were retrospectively extracted from the IBM Watson Health MarketScan® Commercial Claims and Encounters and Medicaid Multi-State databases.

METHODS

Women aged 18-64 years with ≥1 medical claim with a UF diagnosis (primary position, or secondary position plus ≥1 associated symptom) from January 2010 to June 2015 (Commercial) and January 2009 to December 2014 (Medicaid) were eligible; the first UF claim during these time periods was designated the index date. Data collected 12 months pre- and 12 and 60 months post-diagnosis included clinical/demographic characteristics, pharmacologic/surgical treatments, and surgical complications. Prevalence (2015) and cumulative incidence (Commercial, 2010-2015; Medicaid, 2009-2015) of symptomatic UF were estimated.

RESULTS

225,737 (Commercial) and 19,062 (Medicaid) women had a minimum of 12 months post-index continuous enrollment and were eligible for study. Symptomatic UF prevalence and cumulative incidence were: 0.57, 1.23% (Commercial) and 0.46, 0.64% (Medicaid). Initial treatments within 12 months post-diagnosis were surgical (Commercial, 36.7%; Medicaid, 28.7%), pharmacologic (31.7%; 53.0%), or none (31.6%; 18.3%). Pharmacologic treatments were most commonly non-steroidal anti-inflammatory drugs and oral contraceptives; hysterectomy was the most common surgical treatment. Of procedures of abdominal hysterectomy, abdominal myomectomy, uterine artery embolization, and ablation in the first 12 months post-index, 14.9% (Commercial) and 24.9% (Medicaid) resulted in a treatment-associated complication. Abdominal hysterectomy had the highest complication rates (Commercial, 18.5%; Medicaid, 31.0%).

CONCLUSIONS

Off-label use of pharmacologic therapies and hysterectomy for treatment of symptomatic UF suggests a need for indicated non-invasive treatments for symptomatic UF.

Progestin therapy for obese women with complex atypical hyperplasia: levonorgestrel-releasing intrauterine device vs systemic therapy

BACKGROUND

Though hysterectomy remains the standard treatment for complex atypical hyperplasia, patients who desire fertility or who are poor surgical candidates may opt for progestin therapy. However, the effectiveness of the levonorgestrel-releasing intrauterine device compared to systemic therapy in the treatment of complex atypical hyperplasia has not been well studied.

OBJECTIVE

We sought to examine differences in treatment response between local progestin therapy with the levonorgestrel-releasing intrauterine device and systemic progestin therapy in women with complex atypical hyperplasia.

METHODS

This single-institution retrospective study examined women with complex atypical hyperplasia who received progestin therapy between 2003 and 2018. Treatment response was assessed by histopathology on subsequent biopsies. Time-dependent analyses of complete response and progression to cancer were performed comparing the levonorgestrel-releasing intrauterine device and systemic therapy. A propensity score inverse probability of treatment weighting model was used to create a weighted cohort that differed based on treatment type but was similar with respect to other characteristics. An interaction-term analysis was performed to examine the impact of body habitus on treatment response, and an interrupted time-series analysis was employed to assess if changes in treatment patterns correlated with outcomes over time.

RESULTS

A total of 245 women with complex atypical hyperplasia received progestin therapy (levonorgestrel-releasing intrauterine device n = 69 and systemic therapy n = 176). The mean age and body mass index were 36.9 years and 40.0 kg/m², respectively. In the patient-level analysis, women who received the levonorgestrel-releasing intrauterine device had higher rates of complete response (78.7% vs 46.7%; adjusted hazard ratio, 3.32; 95% confidence interval, 2.39-4.62) and a lower likelihood of progression to cancer (4.5% vs 15.7%; adjusted hazard ratio, 0.28; 95% confidence interval, 0.11-0.73) compared to those who received systemic therapy. In particular, women with class III obesity derived a higher relative benefit from levonorgestrel-releasing intrauterine device therapy in achieving complete response compared to systemic therapy: class III obesity, adjusted hazard ratio 4.72, 95% confidence interval 2.83-7.89; class I-II obesity, adjusted hazard ratio 1.83, 95% confidence interval 1.09-3.09; and nonobese, adjusted hazard ratio 1.26, 95% confidence interval 0.40-3.95. In the cohort-level analysis, the obesity rate increased during the study period (77.8% to 88.2%, 13.4% relative increase, P = .033) and levonorgestrel-releasing intrauterine device use significantly increased after 2007 (6.3% to 82.7%, 13.2-fold increase, P < .001), both concomitant with a higher proportion of women achieving complete response (32.9% to 81.4%, 2.5-fold increase, P = .005).

CONCLUSION

Our study suggests that local therapy with the levonorgestrel-releasing intrauterine device may be more effective than systemic therapy for women with complex atypical hyperplasia who opt for nonsurgical treatment, particularly in morbidly obese women. Shifts in treatment paradigm during the study period toward increased levonorgestrel-releasing intrauterine device use also led to improved complete response rates despite increasing rates of obesity.

Progestogen-releasing intrauterine systems for heavy menstrual bleeding

BACKGROUND

Heavy menstrual bleeding (HMB) impacts the quality of life of otherwise healthy women. The perception of HMB is subjective and management depends upon, among other factors, the severity of the symptoms, a woman's age, her wish to get pregnant, and the presence of other pathologies. Heavy menstrual bleeding was classically defined as greater than or equal to 80 mL of blood loss per menstrual cycle. Currently the definition is based on the woman's perception of excessive bleeding which is affecting her quality of life. The intrauterine device was originally developed as a contraceptive but the addition of progestogens to these devices resulted in a large reduction in menstrual blood loss: users of the levonorgestrel-releasing intrauterine system (LNG-IUS) reported reductions of up to 90%. Insertion may, however, be regarded as invasive by some women, which affects its acceptability.

OBJECTIVES

To determine the effectiveness, acceptability and safety of progestogen-releasing intrauterine devices in reducing heavy menstrual bleeding.

SEARCH METHODS

We searched the Cochrane Gynaecology and Fertility Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL (from inception to June 2019); and we searched grey literature and for unpublished trials in trial registers.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in women of reproductive age treated with LNG-IUS devices versus no treatment, placebo, or other medical or surgical therapy for heavy menstrual bleeding.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data, assessed risk of bias and conducted GRADE assessments of the certainty of evidence.

MAIN RESULTS

We included 25 RCTs (2511 women). Limitations in the evidence included risk of attrition bias and low numbers of participants. The studies compared the following interventions. LNG-IUS versus other medical therapy The other medical therapies were norethisterone acetate, medroxyprogesterone acetate, oral contraceptive pill, mefenamic acid, tranexamic acid or usual medical treatment (where participants could choose the oral treatment that was most suitable). The LNG-IUS may improve HMB, lowering menstrual blood loss according to the alkaline haematin method (mean difference (MD) 66.91 mL, 95% confidence interval (CI) 42.61 to 91.20; 2 studies, 170 women; low-certainty evidence); and the Pictorial Bleeding Assessment Chart (MD 55.05, 95% CI 27.83 to 82.28; 3 studies, 335 women; low-certainty evidence). We are uncertain whether the LNG-IUS may have any effect on women's satisfaction up to one year (RR 1.28, 95% CI 1.01 to 1.63; 3 studies, 141 women; I² = 0%, very low-certainty evidence). The LNG-IUS probably leads to slightly higher quality of life measured with the SF-36 compared with other medical therapy if (MD 2.90, 95% CI 0.06 to 5.74; 1 study: 571 women; moderate-certainty evidence) or with the Menorrhagia Multi-Attribute Scale (MD 13.40, 95% CI 9.89 to 16.91; 1 trial, 571 women; moderate-certainty evidence). The LNG-IUS and other medical therapies probably give rise to similar numbers of women with serious adverse events (RR 0.91, 95% CI 0.63 to 1.30; 1 study, 571 women; moderate-certainty evidence). Women using other medical therapy are probably more likely to withdraw from treatment for any reason (RR 0.49, 95% CI 0.39 to 0.60; 1 study, 571 women, moderate-certainty evidence) and to experience treatment failure than women with LNG-IUS (RR 0.34, 95% CI 0.26 to 0.44; 6 studies, 535 women; moderate-certainty evidence). LNG-IUS versus endometrial resection or ablation (EA) Bleeding outcome results are inconsistent. We are uncertain of the effect of the LNG-IUS compared to EA on rates of amenorrhoea (RR 1.21, 95% CI 0.85 to 1.72; 8 studies, 431 women; I² = 21%; low-certainty evidence) and hypomenorrhoea (RR 0.98, 95% CI 0.73 to 1.33; 4 studies, 200 women; low-certainty evidence) and eumenorrhoea (RR 0.55, 95% CI 0.30 to 1.00; 3 studies, 160 women; very low-certainty evidence). We are uncertain whether both treatments may have similar rates of satisfaction with treatment at 12 months (RR 0.95, 95% CI 0.85 to 1.07; 5 studies, 317 women; low-certainty evidence). We are uncertain if the LNG-IUS compared to EA has any effect on quality of life, measured with SF-36 (MD -14.40, 95% CI -22.63 to -6.17; 1 study, 33 women; very low-certainty evidence). Women with the LNG-IUS compared with EA are probably more likely to have any adverse event (RR 2.06, 95% CI 1.44 to 2.94; 3 studies, 201 women; moderate-certainty evidence). Women with the LNG-IUS may experience more treatment failure compared to EA at one year follow up (persistent HMB or requirement of additional treatment) (RR 1.78, 95% CI 1.09 to 2.90; 5 studies, 320 women; low-certainty evidence); or requirement of hysterectomy may be higher at one year follow up (RR 2.56, 95% CI 1.48 to 4.42; 3 studies, 400 women; low-certainty evidence). LNG-IUS versus hysterectomy We are uncertain whether the LNG-IUS has any effect on HMB compared with hysterectomy (RR for amenorrhoea 0.52, 95% CI 0.39 to 0.70; 1 study, 75 women; very low-certainty evidence). We are uncertain whether there is difference between LNG-IUS and hysterectomy in satisfaction at five years (RR 1.01, 95% CI 0.94 to 1.08; 1 study, 232 women; low-certainty evidence) and quality of life (SF-36 MD 2.20, 95% CI -2.93 to 7.33; 1 study, 221 women; low-certainty evidence). Women in the LNG-IUS group may be more likely to have treatment failure requiring hysterectomy for HMB at 1-year follow-up compared to the hysterectomy group (RR 48.18, 95% CI 2.96 to 783.22; 1 study, 236 women; low-certainty evidence). None of the studies reported cost data suitable for meta-analysis.

AUTHORS' CONCLUSIONS

The LNG-IUS may improve HMB and quality of life compared to other medical therapy; the LNG-IUS is probably similar for HMB compared to endometrial destruction techniques; and we are uncertain if it is better or worse than hysterectomy. The LNG-IUS probably has similar serious adverse events to other medical therapy and it is more likely to have any adverse events than EA.

Two-Pronged Treatment of Hemoperitoneum and Abnormal Uterine Bleeding in an Adolescent Girl With Congenital Fibrinogen Deficiency

Introduction: If a woman suffers from congenital fibrinogen deficiency (CFD), she might undergo hypermenorrhea monthly and possibly to suffer from hemoperitoneum due to a ruptured follicle or corpus luteal cyst every month, which seriously threaten her health and quality of life. Here, we creatively used a combination of the levonorgestrel-releasing intrauterine system (LNG-IUS) and the combined oral contraceptives (COC) for a girl with CFD. Case presentation: A 14-year-old girl presented with no obvious cause of persistent and severe lower abdominal pain that began 8 h prior. After examination, she was diagnosed as hemoperitoneum. CFD was diagnosed when she was 2 years old and she had two hospitalizations due to hemorrhagic anemia caused by menorrhagia. Therefore, after successful conservative treatment of hemoperitoneum, a combination of LNG-IUS and COC was used for the long-term conservative management of hypermenorrhea and hemoperitoneum. During the half-year of follow-up, she had hypomenorrhea without hemoperitoneum. Conclusions: To the best of our knowledge, this was the first patient treated with such a procedure in the literature, and we recommend every woman with CFD at puberty or reproductive age receives this two-pronged treatment.

A Multiwell Microfluidic Device for Analyzing and Screening Nonhormonal Contraceptive Agents

Birth control and family planning play pivotal roles in the economic growth and reduction of maternal, infant, and child mortality. Current contraceptives, such as hormonal agents and intrauterine devices, target only a small subset of reproductive processes and can have serious side effects on the health of women. To develop novel contraceptive agents, a scalable microfluidic device is established for analyzing and screening the effects of potential contraceptive agents on the maturation of the cumulus-oocyte complex. The microfluidic device performs on-chip incubation for studying oocyte maturation and cumulus expansion and isolates the microwells by oil-water interfaces to avoid crosstalk between the wells. A filter membrane is incorporated in the device to simplify incubation, medium exchange, washing, and fluorescence staining of oocytes. Cumulus expansion can be monitored directly in the device and oocyte maturation can be examined after enzymatic removal of cumulus cells and on-chip fluorescence staining. The performance of the device is evaluated by studying the influence of three drugs known to block oocyte maturation and/or cumulus expansion.

Endometrial sampling in low-risk patients with abnormal uterine bleeding: a systematic review and meta-synthesis

BACKGROUND

One million women per year seek medical advice for abnormal uterine bleeding (AUB) in the United Kingdom. Many low-risk patients who could be managed exclusively in primary care are referred to hospital based gynaecology services. Performing endometrial sampling (ES) in the community may improve care, reduce the rate of referrals and minimise costs. We aimed to search and synthesise the literature on the effectiveness of ES (Pipelle versus other devices) in managing AUB in low-risk patients.

METHODS

We undertook an electronic literature search in MEDLINE via OvidSP, Scopus, and Web of Science for relevant English-language articles from 1984 to 2016 using a combination of MeSH and keywords. Two reviewers independently pre-selected 317 articles and agreed on 60 articles reporting data from over 7300 patients. Five themes were identified: sample adequacy, test performance, pain and discomfort, cost-effectiveness, and barriers and complications of office ES.

RESULTS

Pipelle seems to perform as well as dilation and curettage and, as well or better than other ES devices in terms of sampling adequacy and sensitivity. It also seems to be better regarding pain/discomfort and costs. However, Pipelle can disrupt the sonographic appearance of the endometrium and may be limited by cervical stenosis, pelvic organ prolapse and endometrial atrophy.

CONCLUSIONS

The current evidence supports the use of Pipelle in the management of low-risk women presenting in the outpatient setting with symptomatic AUB when combined with clinical assessment and ultrasound scanning. However, the implications of its widespread use in primary care are uncertain and more research is required.

A Comprehensive Review of the Pharmacologic Management of Uterine Leiomyoma

Uterine leiomyomata are the most common benign tumors of the gynecologic tract impacting up to 80% of women by 50 years of age. It is well established that these tumors are the leading cause for hysterectomy with an estimated total financial burden greater than $30 billion per year in the United States. However, for the woman who desires future fertility or is a poor surgical candidate, definitive management with hysterectomy is not an optimal management plan. Typical gynecologic symptoms of leiomyoma include infertility, abnormal uterine bleeding (AUB)/heavy menstrual bleeding (HMB) and/or intermenstrual bleeding (IMB) with resulting iron-deficiency anemia, pelvic pressure and pain, urinary incontinence, and dysmenorrhea. The morbidity caused by these tumors is directly attributable to increases in tumor burden. Interestingly, leiomyoma cells within a tumor do not rapidly proliferate, but rather the increase in tumor size is secondary to production of an excessive, stable, and aberrant extracellular matrix (ECM) made of disorganized collagens and proteoglycans. As a result, medical management should induce leiomyoma cells toward dissolution of the extracellular matrix, as well as halting or inhibiting cellular proliferation. Herein, we review the current literature regarding the medical management of uterine leiomyoma.

Hysterectomy for Benign Uterine Disease

BACKGROUND

Hysterectomy is the second most common operation in obstetrics and gynecology after Cesarean section. Until now, there has not been any German clinical guideline with recommendations concerning the indications for hysterectomy for benign uterine conditions, in consideration of the available uterus-preserving alternative treatments.

METHODS

We systematically searched the Medline database in 2013, in 2014, and in December 2015, focusing on aggregate evidence, and assessed the retrieved literature. The guideline recommendations were developed by a consensus process with structured independent moderation.

RESULTS

30 systematic reviews and 8 randomized controlled trials were analyzed. Among the study patients treated with either hysterectomy (by any technique) or an organ-preserving alternative, at least 75-94% were satisfied with their treatment. Vaginal hysterectomy was associated with lower complication rates, shorter procedure duration, and more rapid recovery than abdominal hysterectomy and is therefore the preferred technique. If vaginal hysterectomy is not possible, a laparoscopic approach should be considered. Abdominal hysterectomy should be reserved for special indications. In 2012, the frequency of abdominal hysterectomy in Germany, Austria, and Switzerland was lower than elsewhere in the world, at 15.7% , 28.0% , and 23.9% , respectively. Uterus-preserving techniques were associated with higher reintervention rates compared to hysterectomy (11-36% vs 4-10% ).

CONCLUSION

The main objective is to reduce the frequency of abdominal hysterectomy. Patients should be counseled and made aware of uterus-sparing alternatives to hysterectomy so that they are able to make informed decisions.

Usual medical treatments or levonorgestrel-IUS for women with heavy menstrual bleeding: long-term randomised pragmatic trial in primary care

Background

Heavy menstrual bleeding (HMB) is a common, chronic problem affecting women and health services. However, long-term evidence on treatment in primary care is lacking.

Aim

To assess the effectiveness of commencing the levonorgestrel-releasing intrauterine system (LNG-IUS) or usual medical treatments for women presenting with HMB in general practice.

Design and setting

A pragmatic, multicentre, parallel, open-label, long term, randomised controlled trial in 63 primary care practices across the English Midlands.

Method

In total, 571 women aged 25–50 years, with HMB were randomised to LNG-IUS or usual medical treatment (tranexamic/mefenamic acid, combined oestrogen–progestogen, or progesterone alone). The primary outcome was the patient reported Menorrhagia Multi-Attribute Scale (MMAS, measuring effect of HMB on practical difficulties, social life, psychological and physical health, and work and family life; scores from 0 to 100). Secondary outcomes included surgical intervention (endometrial ablation/hysterectomy), general quality of life, sexual activity, and safety.

Results

At 5 years post-randomisation, 424 (74%) women provided data. While the difference between LNG-IUS and usual treatment groups was not significant (3.9 points; 95% confidence interval = −0.6 to 8.3; P = 0.09), MMAS scores improved significantly in both groups from baseline (mean increase, 44.9 and 43.4 points, respectively; P<0.001 for both comparisons). Rates of surgical intervention were low in both groups (surgery-free survival was 80% and 77%; hazard ratio 0.90; 95% CI = 0.62 to 1.31; P = 0.6). There was no difference in generic quality of life, sexual activity scores, or serious adverse events.

Conclusion

Large improvements in symptom relief across both groups show treatment for HMB can be successfully initiated with long-term benefit and with only modest need for surgery.

A randomised controlled trial of the clinical effectiveness and cost-effectiveness of the levonorgestrel-releasing intrauterine system in primary care against standard treatment for menorrhagia: the ECLIPSE trial

BACKGROUND

Heavy menstrual bleeding (HMB) is a common problem, yet evidence to inform decisions about initial medical treatment is limited.

OBJECTIVES

To assess the clinical effectiveness and cost-effectiveness of the levonorgestrel-releasing intrauterine system (LNG-IUS) (Mirena®, Bayer) compared with usual medical treatment, with exploration of women's perspectives on treatment.

DESIGN

A pragmatic, multicentre randomised trial with an economic evaluation and a longitudinal qualitative study.

SETTING

Women who presented in primary care.

PARTICIPANTS

A total of 571 women with HMB. A purposeful sample of 27 women who were randomised or ineligible owing to treatment preference participated in semistructured face-to-face interviews around 2 and 12 months after commencing treatment.

INTERVENTIONS

LNG-IUS or usual medical treatment (tranexamic acid, mefenamic acid, combined oestrogen-progestogen or progesterone alone). Women could subsequently swap or cease their allocated treatment.

OUTCOME MEASURES

The primary outcome was the patient-reported score on the Menorrhagia Multi-Attribute Scale (MMAS) assessed over a 2-year period and then again at 5 years. Secondary outcomes included general quality of life (QoL), sexual activity, surgical intervention and safety. Data were analysed using iterative constant comparison. A state transition model-based cost-utility analysis was undertaken alongside the randomised trial. Quality-adjusted life-years (QALYs) were derived from the European Quality of Life-5 Dimensions (EQ-5D) and the Short Form questionnaire-6 Dimensions (SF-6D). The intention-to-treat analyses were reported as cost per QALY gained. Uncertainty was explored by conducting both deterministic and probabilistic sensitivity analyses.

RESULTS

The MMAS total scores improved significantly in both groups at all time points, but were significantly greater for the LNG-IUS than for usual treatment [mean difference over 2 years was 13.4 points, 95% confidence interval (CI) 9.9 to 16.9 points; p < 0.001]. However, this difference between groups was reduced and no longer significant by 5 years (mean difference in scores 3.9 points, 95% CI -0.6 to 8.3 points; p = 0.09). By 5 years, only 47% of women had a LNG-IUS in place and 15% were still taking usual medical treatment. Five-year surgery rates were low, at 20%, and were similar, irrespective of initial treatments. There were no significant differences in serious adverse events between groups. Using the EQ-5D, at 2 years, the relative cost-effectiveness of the LNG-IUS compared with usual medical treatment was £1600 per QALY, which by 5 years was reduced to £114 per QALY. Using the SF-6D, usual medical treatment dominates the LNG-IUS. The qualitative findings show that women's experiences and expectations of medical treatments for HMB vary considerably and change over time. Women had high expectations of a prompt effect from medical treatments.

CONCLUSIONS

The LNG-IUS, compared with usual medical therapies, resulted in greater improvement over 2 years in women's assessments of the effect of HMB on their daily routine, including work, social and family life, and psychological and physical well-being. At 5 years, the differences were no longer significant. A similar low proportion of women required surgical intervention in both groups. The LNG-IUS is cost-effective in both the short and medium term, using the method generally recommended by the National Institute for Health and Care Excellence. Using the alternative measures to value QoL will have a considerable impact on cost-effectiveness decisions. It will be important to explore the clinical and health-care trajectories of the ECLIPSE (clinical effectiveness and cost-effectiveness of levonorgestrel-releasing intrauterine system in primary care against standard treatment for menorrhagia) trial participants to 10 years, by which time half of the cohort will have reached menopause.

Challenges of diagnosing and managing the adolescent with heavy menstrual bleeding

Unpredictable, prolonged or heavy menstrual bleeding (HMB) may be expected for many adolescents soon after menarche. A decade of clinical experience and research has now established firmly that bleeding disorders (BD) are common in adolescents with HMB. Despite these advances, many questions remain, and several aspects of the diagnosis and management of BDs in adolescents are not supported by rigorous clinical trials. In this overview, four major areas will be discussed. First, we will discuss the frequency of BDs in young women with HMB. Up to 20% of older females with HMB are thought to have an underlying BD. Estimates from retrospective studies in adolescents suggest a prevalence that varies anywhere from 10 to 62%. Prospective studies with uniform hemostatic evaluation are needed to answer this question definitively. Second, we will review existing tools that help screen and diagnose adolescents with HMB with an underlying BD. Although identification of an underlying BD in older women with HMB is relatively straight forward, uncertainties remain for adolescents. Heavy menstrual bleeding in this age group may have different pathophysiological underpinnings than those in older women and may often be disregarded as anovulatory. There is an urgent need to develop novel tools, and evaluate existing diagnostic strategies in adolescents. Third, we will discuss the optimal medical management of HMB in young adolescents. As direct evidence is largely lacking, these areas are also subject to extrapolation from older women. Lastly, an important area- prediction, and management of future bleeding in those adolescents who are diagnosed with a mild BD-will be discussed. Throughout, areas of controversy and opportunities for further research are highlighted.

Indications and Route of Hysterectomy for Benign Diseases. Guideline of the DGGG, OEGGG and SGGG (S3 Level, AWMF Registry No. 015/070, April 2015)

Background: Official guideline "indications and methods of hysterectomy" to assign indications for the different methods published and coordinated by the German Society of Gynecology and Obstetrics (DGGG), the Austrian Society of Gynecology and Obstetrics (OEGGG) and the Swiss Society of Gynecology and Obstetrics (SGGG). Besides vaginal and abdominal hysterectomy, three additional techniques have been implemented due to the introduction of laparoscopy. Organ-sparing alternatives were also integrated. Methods: The guideline group consisted of 26 experts from Germany, Austria and Switzerland. Recommendations were developed using a structured consensus process and independent moderation. A systematic literature search and quality appraisal of benefits and harms of the therapeutic alternatives for symptomatic fibroids, dysfunctional bleeding and adenomyosis was done through MEDLINE up to 6/2014 focusing on systematic reviews and meta-analysis. Results: All types of hysterectomy led in studies to high rates of patient satisfaction. If possible, vaginal instead of abdominal hysterectomy should preferably be done. If a vaginal hysterectomy is not feasible, the possibility of a laparoscopic hysterectomy should be considered. An abdominal hysterectomy should only be done with a special indication. Organ-sparing interventions also led to high patient satisfaction rates, but contain the risk of symptom recurrence. Conclusion: As an aim, patients should be enabled to choose that therapeutic intervention for their benign disease of the uterus that convenes best to them and their personal life situation.

Comparison of Therapeutic Efficacies of Norethisterone, Tranexamic Acid and Levonorgestrel-Releasing Intrauterine System for the Treatment of Heavy Menstrual Bleeding: A Randomized Controlled Study

BACKGROUND

Our aim was to compare the therapeutic efficacies of norethisterone acid (NETA), tranexamic acid and levonorgestrel-releasing intrauterine system (LNG-IUS) in treating idiopathic heavy menstrual bleeding (HMB).

METHODS

Women with heavy uterine bleeding were randomized to receive NETA, tranexamic acid or LNG-IUS for 6 months. The primary outcome was a decrease in menstrual bleeding as assessed by pictorial blood loss assessment charts and hematological parameters analyzed at the 1st, 3rd and 6th months. Health-related quality of life (QOL) variables were also recorded and analyzed.

RESULTS

Twenty-eight patients were enrolled in each treatment group, but the results of only 62 were evaluated. NETA, tranexamic acid, and LNG-IUS reduced menstrual blood loss (MBL) by 53.1, 60.8, and 85.8%, respectively, at the 6th month. LNG-IUS was more effective than NETA and tranexamic acid in decreasing MBL. LNG-IUS was also more efficient than tranexamic acid in correcting anemia related to menorrhagia. Satisfaction rates were comparable among the NETA (70%), tranexamic acid (63%) and LNG-IUS (77%) groups. QOL in physical aspects increased significantly in the tranexamic acid and LNG-IUS groups.

CONCLUSION

The positive effect of LNG-IUS on QOL parameters, as well as its high efficacy, makes it a first-line option for HMB.

Progesterone or progestogen-releasing intrauterine systems for heavy menstrual bleeding

BACKGROUND

Heavy menstrual bleeding (HMB) is an important cause of ill health in women and it accounts for 12% of all gynaecology referrals in the UK. Heavy menstrual bleeding is clinically defined as greater than or equal to 80 mL of blood loss per menstrual cycle. However, women may complain of excessive bleeding when their blood loss is less than 80 mL. Hysterectomy is often used to treat women with this complaint but medical therapy may be a successful alternative.The intrauterine device was originally developed as a contraceptive but the addition of progestogens to these devices resulted in a large reduction in menstrual blood loss. Case studies of two types of progesterone or progestogen-releasing systems, Progestasert and Mirena, reported reductions of up to 90% and improvements in dysmenorrhoea (pain or cramps during menstruation). Insertion, however, may be regarded as invasive by some women, which affects its acceptability as a treatment. Frequent intermenstrual bleeding and spotting is also likely during the first few months after commencing treatment.

OBJECTIVES

To determine the effectiveness, acceptability and safety of progesterone or progestogen-releasing intrauterine devices in achieving a reduction in heavy menstrual bleeding.

SEARCH METHODS

All randomised controlled trials of progesterone or progestogen-releasing intrauterine devices for the treatment of heavy menstrual bleeding were obtained by electronic searches of The Cochrane Library, the specialised register of MDSG, MEDLINE (1966 to January 2015), EMBASE (1980 to January 2015), CINAHL (inception to December 2014) and PsycINFO (inception to January 2015). Additional searches were undertaken for grey literature and for unpublished trials in trial registers. Companies producing progestogen-releasing intrauterine devices and experts in the field were contacted for information on published and unpublished trials.

SELECTION CRITERIA

Randomised controlled trials in women of reproductive age treated with progesterone or progestogen-releasing intrauterine devices versus no treatment, placebo, or other medical or surgical therapy for heavy menstrual bleeding within primary care, family planning or specialist clinic settings were eligible for inclusion. Women with postmenopausal bleeding, intermenstrual or irregular bleeding, or pathological causes of heavy menstrual bleeding were excluded.

DATA COLLECTION AND ANALYSIS

Potential trials were independently assessed by at least two review authors. The review authors extracted the data independently and data were pooled where appropriate. Risk ratios (RRs) were estimated from the data for dichotomous outcomes and mean differences (MD) for continuous outcomes. The primary outcomes were reduction in menstrual blood loss and satisfaction; in addition, rate of adverse effects, changes in quality of life, failure of treatment and withdrawal from treatment were also assessed.

MAIN RESULTS

We included 21 RCTs (2082 women). The included trials mostly assessed the levonorgestrel-releasing intrauterine device (LNG IUS) (no conclusions could be reached from one small study assessing Progestasert which was discontinued in 2001) and so conclusions are based only on LNG IUS. Comparisons were made with placebo, oral medical treatment, endometrial destruction techniques and hysterectomy. Ratings for the overall quality of the evidence for each comparison ranged from very low to high. Limitations in the evidence included inadequate reporting of study methods and inconsistency.Seven studies compared the LNG IUS with oral medical therapy: either norethisterone acetate (NET) administered over most of the menstrual cycle, medroxyprogesterone acetate (MPA) (administered for 10 days), the oral contraceptive pill, mefenamic acid or usual medical treatment where participants could choose the oral treatment that was most suitable. The LNG IUS was more effective at reducing HMB as measured by the alkaline haematin method (MD 66.91 mL, 95% CI 42.61 to 91.20; two studies, 170 women; I(2) = 81%, low quality evidence) or by Pictorial Bleeding Assessment Chart (PBAC) scores (MD 55.05, 95% CI 27.83 to 82.28; three studies, 335 women; I(2) = 79%, low quality evidence), improving quality of life and a greater number of women continued with their treatment at two years when compared with oral treatment. Although substantial heterogeneity was identified for the bleeding outcomes, the direction of effect consistently favoured the LNG IUS. There was insufficient evidence to reach conclusions on satisfaction. Minor adverse effects (such as pelvic pain, breast tenderness and ovarian cysts) were more common with the LNG IUS.Ten studies compared the LNG IUS with endometrial destruction techniques: three with transcervical resection, one with rollerball ablation and six with thermal balloon ablation. Evidence was inconsistent and very low quality with respect to reduction in bleeding outcomes and satisfaction was comparable between treatments (low and moderate quality evidence). Improvements in quality of life were experienced with both types of treatment. Minor adverse events were more common with the LNG IUS overall, but it appeared more cost effective compared to thermal ablation within a two-year time frame in one study.Three studies compared the LNG IUS with hysterectomy. The LNG IUS was not as successful at reducing HMB as hysterectomy (high quality evidence). The women in these studies reported improved quality of life, regardless of treatment. In spite of the high rate of surgical treatment in those having LNG IUS within 10 years, the LNG IUS was more cost effective than hysterectomy.

AUTHORS' CONCLUSIONS

The levonorgestrel-releasing intrauterine device (LNG IUS) is more effective than oral medication as a treatment for heavy menstrual bleeding (HMB). It is associated with a greater reduction in HMB, improved quality of life and appears to be more acceptable long term but is associated with more minor adverse effects than oral therapy.When compared to endometrial ablation, it is not clear whether the LNG IUS offers any benefits with regard to reduced HMB and satisfaction rates and quality of life measures were similar. Some minor adverse effects were more common with the LNG IUS but it appeared to be more cost effective than endometrial ablation techniques.The LNG IUS was less effective than hysterectomy in reducing HMB. Both treatments improved quality of life but the LNG IUS appeared more cost effective than hysterectomy for up to 10 years after treatment.

Management of endometrial modifications in perimenopausal women

Perimenopause has a variable length and time of onset and is characterized by its variability in hormonal levels. The histological changes in the perimenopausal endometrium may be represented by nonproliferative or proliferative benign or malignant lesions. A commonly encountered manifestation of endometrium lesions during menopausal transition is the abnormal uterine bleeding (AUB). The clinical management of AUB must follow a standardized classification system for optimal results. The medical and surgical treatment must be adapted according to age, risk factors, symptoms, and cycle irregularities. Use of alternative therapies and proper diet may result in improved long-term outcomes.

Controlled release for local delivery of drugs: barriers and models

Controlled release systems are an effective means for local drug delivery. In local drug delivery, the major goal is to supply therapeutic levels of a drug agent at a physical site in the body for a prolonged period. A second goal is to reduce systemic toxicities, by avoiding the delivery of agents to non-target tissues remote from the site. Understanding the dynamics of drug transport in the vicinity of a local drug delivery device is helpful in achieving both of these goals. Here, we provide an overview of controlled release systems for local delivery and we review mathematical models of drug transport in tissue, which describe the local penetration of drugs into tissue and illustrate the factors - such as diffusion, convection, and elimination - that control drug dispersion and its ultimate fate. This review highlights the important role of controlled release science in development of reliable methods for local delivery, as well as the barriers to accomplishing effective delivery in the brain, blood vessels, mucosal epithelia, and the skin.

Levonorgestrel-releasing intrauterine system versus medical therapy for menorrhagia: a systematic review and meta-analysis

Background

The aim of this study was to compare the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) with conventional medical treatment in reducing heavy menstrual bleeding.

Material/Methods

Relevant studies were identified by a search of MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and clinical trials registries (from inception to April 2014). Randomized controlled trials comparing the LNG-IUS with conventional medical treatment (mefenamic acid, tranexamic acid, norethindrone, medroxyprogesterone acetate injection, or combined oral contraceptive pills) in patients with menorrhagia were included.

Results

Eight randomized controlled trials that included 1170 women (LNG-IUS, n=562; conventional medical treatment, n=608) met inclusion criteria. The LNG-IUS was superior to conventional medical treatment in reducing menstrual blood loss (as measured by the alkaline hematin method or estimated by pictorial bleeding assessment chart scores). More women were satisfied with the LNG-IUS than with the use of conventional medical treatment (odds ratio [OR] 5.19, 95% confidence interval [CI] 2.73–9.86). Compared with conventional medical treatment, the LNG-IUS was associated with a lower rate of discontinuation (14.6% vs. 28.9%, OR 0.39, 95% CI 0.20–0.74) and fewer treatment failures (9.2% vs. 31.0%, OR 0.18, 95% CI 0.10–0.34). Furthermore, quality of life assessment favored LNG-IUS over conventional medical treatment, although use of various measurements limited our ability to pool the data for more powerful evidence. Serious adverse events were statistically comparable between treatments.

Conclusions

The LNG-IUS was the more effective first choice for management of menorrhagia compared with conventional medical treatment. Long-term, randomized trials are required to further investigate patient-based outcomes and evaluate the cost-effectiveness of the LNG-IUS and other medical treatments.

Molecular aspects of development and regulation of endometriosis

Endometriosis is a common and painful condition affecting women of reproductive age. While the underlying pathophysiology is still largely unknown, much advancement has been made in understanding the progression of the disease. In recent years, a great deal of research has focused on non-invasive diagnostic tools, such as biomarkers, as well as identification of potential therapeutic targets. In this article, we will review the etiology and cellular mechanisms associated with endometriosis as well as the current diagnostic tools and therapies. We will then discuss the more recent genomic and proteomic studies and how these data may guide development of novel diagnostics and therapeutics. The current diagnostic tools are invasive and current therapies primarily treat the symptoms of endometriosis. Optimally, the advancement of "-omic" data will facilitate the development of non-invasive diagnostic biomarkers as well as therapeutics that target the pathophysiology of the disease and halt, or even reverse, progression. However, the amount of data generated by these types of studies is vast and bioinformatics analysis, such as we present here, will be critical to identification of appropriate targets for further study.

Impact of a new levonorgestrel intrauterine system, Levosert(®), on heavy menstrual bleeding: results of a one-year randomised controlled trial

Objective

To evaluate a new levonorgestrel-releasing intrauterine system (LNG-IUS) called Levosert^® for the treatment of heavy menstrual bleeding (HMB) in comparison to the reference product Mirena^®.

Methods

A multicentre, randomised, controlled trial, in non-menopausal women diagnosed with functional HMB (defined as menstrual blood loss [MBL] ≥ 80 mL) randomised to either Levosert^® or Mirena^® and followed for up to one year. MBL was evaluated using a validated modified version of the Wyatt pictogram.

Results

A total of 280 women were randomised (141 to Levosert^® and 139 to Mirena^®). During the one-year treatment period, both Levosert^® and Mirena^® dramatically decreased MBL and increased haemoglobin and ferritin levels. There were no statistically significant differences between Levosert^® and Mirena^® regarding any of the parameters evaluated during the study. Similar bleeding patterns were observed in both groups. Levosert^® was inserted with the same ease as Mirena^®. Both treatments were associated with identical expulsion rates and no perforations occurred in either treatment group.

Conclusion

Levosert^®, a new LNG-IUS designed to release the same daily amount of LNG as Mirena^®, is highly effective in the treatment of HMB. No differences were observed between Levosert^® and Mirena^® regarding all evaluated outcomes, including safety profile.

Levonorgestrel releasing intrauterine system (Mirena) versus endometrial ablation (Novasure) in women with heavy menstrual bleeding: a multicentre randomised controlled trial

BACKGROUND

Heavy menstrual bleeding is an important health problem. Two frequently used therapies are the levonorgestrel intra-uterine system (LNG-IUS) and endometrial ablation. The LNG-IUS can be applied easily by the general practitioner, which saves costs, but has considerable failure rates. As an alternative, endometrial ablation is also very effective, but this treatment has to be performed by a gynaecologist. Due to lack of direct comparison of LNG-IUS with endometrial ablation, there is no evidence based preferred advice for the use of one of these treatment possibilities.

METHOD/DESIGN

A multicenter randomised controlled trial, organised in a network infrastructure in the Netherlands in which general practitioners and gynaecologists collaborate.

DISCUSSON

This study, considering both effectiveness and cost effectiveness of LNG-IUS versus endometrial ablation may well improve care for women with heavy menstrual bleeding.

TRIAL REGISTRATION

Dutch trial register, number NTR2984.

Nationwide trends in the performance of inpatient hysterectomy in the United States

OBJECTIVE

To examine the use of inpatient hysterectomy and explore changes in the use of various routes of hysterectomy and patterns of referral.

METHODS

The Nationwide Inpatient Sample was used to identify all women aged 18 years or older who underwent inpatient hysterectomy between 1998 and 2010. Weighted estimates of national trends were calculated and the number of procedures performed estimated. Trends in hospital volume and across hospital characteristics were examined.

RESULTS

After weighting, we identified a total 7,438,452 women who underwent inpatient hysterectomy between 1998 and 2010. The number of hysterectomies performed annually rose from 543,812 in 1998 to a peak of 681,234 in 2002; it then declined consistently annually and reached 433,621 cases in 2010. Overall, 247,973 (36.4%) fewer hysterectomies were performed in 2010 compared with 2002. From 2002 to 2010 the number of hysterectomies performed for each of the following indications declined: leiomyoma (-47.6%), abnormal bleeding (-28.9%), benign ovarian mass (-63.1%), endometriosis (-65.3%), and pelvic organ prolapse (-39.4%). The median hospital case volume decreased from 83 procedures per year in 2002 to 50 cases per year in 2010 (P<.001).

CONCLUSION

The number of inpatient hysterectomies performed in the United States has declined substantially over the past decade. The median number of hysterectomies per hospital has declined likewise by more than 40%.

Levonorgestrel intrauterine system: Current role in management of heavy menstrual bleeding

A review of literature was conducted to report on the effectiveness of levonorgestrel intrauterine system (LNG-IUS) in women with heavy menstrual bleeding (HMB). The relevant data were obtained by computerized searches of PubMed up to December 2012 and other references available with the authors. Information was obtained from references listed. Studies and case reports were excluded if they did not specifically provide information about LNG-IUS usage in women with HMB. After perusal, each relevant publication was summarized and appraised in terms of whether it contained information relevant to the stated objective. Available data shows that LNG-IUS therapy is effective and safe, providing significant reduction of menstrual bleeding in patients with HMB. LNG-IUS is a good strategy to reduce the number of hysterectomies in women with HMB.

Novel oral contraceptive for heavy menstrual bleeding: estradiol valerate and dienogest

Abnormal uterine bleeding (AUB) is associated with significant direct medical costs and impacts both society and the quality of life for individual women. Heavy menstrual bleeding, a subset of AUB, also referred to as menorrhagia, is defined as menstrual blood loss greater than 80 mL or the patient’s perception of excessive blood loss. The newest treatment option available is a novel combination oral contraceptive product containing estradiol valerate (E2V) and dienogest (DNG). As with other combination oral contraceptives, E2V/DNG works primarily by preventing ovulation. However, in contrast with other combination oral contraceptives, it is the progestin component of E2V/DNG that is responsible for endometrial stabilization. Use of E2V/DNG for six months has led to significant reductions in heavy menstrual bleeding with an average 65% reduction in mean blood loss. Approximately half of the women with heavy menstrual bleeding who received E2V/DNG for six months demonstrated an 80% reduction in mean blood loss. Additionally, significant improvements in hematologic indicators (ie, ferritin, hemoglobin, and hematocrit) have been shown. Based on its chemical properties, E2V/DNG may have fewer adverse effects on lipid and glucose metabolism and reduced risk of thromboembolic complications compared with other combination oral contraceptives. This has not yet been shown in clinical trials and until then it should be assumed that E2V/DNG has a safety profile similar to other combination oral contraceptives containing 35 μg or less of ethinyl estradiol. E2V/DNG has been compared with another combination oral contraceptive in healthy women without heavy menstrual bleeding and demonstrated improved bleeding patterns. E2V/DNG has not been compared with the levonorgestrel intrauterine device or other treatments for heavy menstrual bleeding. When compared with some other treatment options for AUB, E2V/DNG provides the added advantage of effective contraception.

Clinical applications of levonorgestrel-releasing intrauterine system to gynecologic diseases

The levonorgestrel-releasing intrauterine system (LNG-IUS), originally designed for contraception, has since been applied to various gynecologic diseases. This article summarizes the current status of clinical applications of LNG-IUS to the treatment of gynecologic diseases such as heavy menstrual bleeding, endometriosis, leiomyoma, adenomyosis, endometrial hyperplasia, and early-stage endometrial cancer.

The cost-effectiveness of the levonorgestrel-releasing intrauterine system for the treatment of idiopathic heavy menstrual bleeding in the United States

OBJECTIVES

Heavy menstrual bleeding negatively impacts the health and quality of life of about 18 million women in the United States. Although some studies have established the clinical effectiveness of heavy menstrual bleeding treatments, few have evaluated their cost-effectiveness. Our objective was to evaluate the cost-effectiveness of the levonorgestrel-releasing intrauterine system (LNG-IUS) compared with other therapies for idiopathic heavy menstrual bleeding.

METHODS

We developed a model comparing the clinical and economic outcomes (from a US payer perspective) of three broad initial treatment strategies over 5 years: LNG-IUS, oral agents, or surgery. Up to three nonsurgical treatment lines, followed by up to two surgical lines, were allowed; unintended pregnancy was possible, and women could discontinue any time during nonsurgical treatments. Menstrual blood loss of 80 ml or more per cycle determined treatment failure.

RESULTS

Initiating treatment with LNG-IUS resulted in the fewest hysterectomies (6 per 1000 women), the most quality-adjusted life-years (3.78), and the lowest costs ($1137) among all the nonsurgical strategies. Initiating treatment with LNG-IUS was also less costly than surgery, resulted in fewer hysterectomies (vs. 9 per 1000 for ablation) but was associated with fewer quality-adjusted life-years gained per patient (vs. 3.80 and 3.88 for ablation and hysterectomy, respectively). Sensitivity analyses confirmed these results.

CONCLUSIONS

LNG-IUS resulted in the lowest treatment costs and the fewest number of hysterectomies performed over 5 years compared with all other initial strategies and resulted in the most quality-adjusted life-years gained among nonsurgical options. Initial treatment with LNG-IUS is the least costly and most effective option for women desiring to preserve their fertility.

Effect of myoma size on failure of thermal balloon ablation or levonorgestrel releasing intrauterine system treatment in women with menorrhagia

Objective

The aim of the present study was to identify variables associated with treatment failure in women with menorrhagia who were treated with thermal balloon ablation (TBA) or levonorgestrel releasing intrauterine system (LNG-IUS), and to determine if there are subgroups where one treatment type is more effective than the other.

Methods

The study included 106 women with menorrhagia who were treated with TBA or LNG-IUS at the study institute between January 2003 and December 2007, with a follow-up period greater than 12 months. Data were collected by retrospective review of medical records. Treatment failure was defined as persistent or recurrent menorrhagia within one year after treatment or hysterectomy at any time during follow-up. The relationships between variables and treatment outcome were analyzed using the chi-square or Fisher's exact test. The treatment outcome of TBA was compared with LNG-IUS.

Results

Sixty-seven women were treated with TBA and 39 women were managed with LNG-IUS. Fifty-two women had a myoma ≥2.5 cm. Treatment failure was observed in 24 women (2 recurrent or persistent menorrhagia and 22 hysterectomies) and myoma size (≥2.5 cm vs. <2.5 cm) was associated with treatment outcome. TBA and LNG-IUS showed similar treatment outcomes.

Conclusion

A large myoma is a risk factor for treatment failure in women with menorrhagia treated with TBA or LNG-IUS.

Role of the levonorgestrel intrauterine system in effective contraception

Norgestrel, a synthetic progestin chemically derived from 19-nortestosterone, is six times more potent than progesterone, with variable binding affinity to various steroid receptors. The levonorgestrel-releasing intrauterine system (LNG IUS) provides a long-acting, highly effective, and reversible form of contraception, with a pearl index of 0.18 per 100 women-years. The locally released hormone leads to endometrial concentrations that are 200-800 times those found after daily oral use and a plasma level that is lower than that with other forms of levonorgestrel-containing contraception. The contraceptive effect of the LNG IUS is achieved mainly through its local suppressive effect on the endometrium, leading to endometrial thinning, glandular atrophy, and stromal decidualization without affecting ovulation. The LNG IUS is generally well tolerated. The main side effects are related to its androgenic activity, which is usually mild and transient, resolving after the first few months. Menstrual abnormalities are also common but well tolerated, and even become desirable (eg, amenorrhea, hypomenorrhea, and oligomenorrhea) with proper counseling of the patient during the choice of the method of contraception. The satisfaction rates after 3 years of insertion are high, reaching between 77% and 94%. The local effect of the LNG IUS on the endometrium and low rates of systemic adverse effects have led to its use in other conditions rather than contraception, as for the treatment of endometrial hyperplasia, benign menorrhagia, endometriosis, adenomyosis, and uterine fibroids.

Hydronephrosis and loin pain as a presentation of tubo-ovarian abscess developing after Mirena coil removal

We present an unusual and complicated case of a 39-year-old woman who was admitted three times in hospital over a period of 4&emsp14;weeks, with abdominal pain initially and then right loin pain, fever and feeling generally unwell. She was investigated on each admission with different diagnoses set each time, but only on her last admission due to persisting symptoms, an MRI scan revealed a tubo-ovarian abscess associated with pelvic inflammatory disease (PID). We believe that the PID had developed secondary to the intrauterine device and a few weeks after the removal of the Mirena coil she was diagnosed with a tubo-ovarian abscess. As the case unfolds, we will introduce the possible diagnoses and causes that were likely to have led to the development of the abscess.

Practice patterns and attitudes about treating abnormal uterine bleeding: a national survey of obstetricians and gynecologists

OBJECTIVE

We sought to examine the practice patterns and attitudes of obstetricians and gynecologists surrounding treatment of abnormal uterine bleeding (AUB).

STUDY DESIGN

We conducted a cross-sectional study of members of the American College of Obstetricians and Gynecologists. Surveys, which were distributed using a sequential mixed method (both web- and mail-based) approach, included questions about practice characteristics, practice patterns, and knowledge about treatment options for AUB.

RESULTS

Of 802 questionnaires, 417 were returned (52%). The most commonly selected first-line choice for AUB treatment was combined oral contraceptives (97% anovulatory, 98% ovulatory). The levonorgestrel intrauterine system was the next most frequently selected option (63% anovulatory, 53% ovulatory). Respondents did not score high on questions about the effectiveness of treatments for AUB. Only 25% (n = 86) answered at least 2 of the 3 questions correctly.

CONCLUSION

Continued education is necessary to increase the utilization of the most effective treatment options for AUB.

A randomized clinical trial to compare levonorgestrel-releasing intrauterine system (Mirena) vs trans-cervical endometrial resection for treatment of menorrhagia

OBJECTIVE

To compare the acceptability, efficacy, adverse effects, and user satisfaction of the levonorgestrel intrauterine system (LNG-IUS) and trans-cervical resection of the endometrium (TCRE) for the treatment of menorrhagia.

METHOD

104 women with menorrhagia were divided into 2 groups: 52 women had the LNG-IUS inserted and 52 underwent TCRE. Menstrual pattern, pictorial blood loss assessment chart score, adverse effects, and rates of acceptability and satisfaction, were recorded at 6 and 12 months after the procedure.

RESULTS

After a year there were reductions of 93.9% and 88.4% in menstrual blood loss in the TCRE and LNG-IUS groups, respectively. Amenorrhea was more common in the TCRE group and spotting and systemic effects in the LNG-IUS group. Satisfaction rates of the TCRE group were higher than the LNG-IUS group (80.8% vs 69.2%), but the difference was not statistically significant.

CONCLUSION

Although both treatments were found to be equally effective, LNG-IUS was less invasive and can be advised for younger women with a desire to preserve fertility.

Uterine perforation with the levonorgestrel-releasing intrauterine device: analysis of reports from four national pharmacovigilance centres

BACKGROUND

Levonorgestrel-releasing intrauterine devices (LNG-IUD) are commonly used for contraception and other indications in many countries. National pharmacovigilance centres have been receiving reports from healthcare professionals and patients of uterine perforation associated with the use of these LNG-IUDs.

METHODS

National pharmacovigilance centres in the Netherlands, New Zealand, Switzerland and Germany did a search on their adverse drug reaction databases for reports of cases of uterine perforation after insertion of a LNG-IUD received between the introduction of the LNG-IUD onto the market in the late 1990s and 15 July 2007. The number of women affected and patient characteristics such as age, parity and breastfeeding status were examined. In addition, the method of detection of the perforation and the time until discovery of the perforation were analysed.

RESULTS

Between the introduction of the LNG-IUD onto the market in each country and 15 July 2007, 701 cases of uterine perforation with a LNG-IUD were reported; 8.5% of the perforations were detected at the time of insertion. Abdominal pain and control/check-up visits were the most common events that lead to the detection of a perforation. Of 462 women known to be parous, 192 (42%) were breastfeeding at the time the perforation was discovered.

CONCLUSIONS

Uterine perforations can be asymptomatic and may remain undetected for a long time after IUD insertion. Abdominal pain, control/check-up visits or changes in bleeding patterns are triggers for detection of perforation and should therefore be taken seriously.

A randomized clinical trial of a levonorgestrel-releasing intrauterine system and a low-dose combined oral contraceptive for fibroid-related menorrhagia

OBJECTIVE

To compare the efficacy of a levonorgestrel-releasing intrauterine system (LNG-IUS) with that of a low-dose combined oral contraceptive (COC) in reducing fibroid-related menorrhagia.

METHODS

In this single-center, open, randomized clinical trial, 58 women with menorrhagia who desired contraception were randomized to receive a LNG-IUS or COC. The outcomes included treatment failure, defined as the need for another treatment; menstrual blood loss (MBL) by the alkaline hematin method and a pictorial assessment chart (PBAC); hemoglobin levels; and "lost days."

RESULTS

Treatment failed in 6 women (23.1%) in the LNG-IUS group and 11 (37.9%) in the COC group, for a hazard ratio of 0.46 (95% CI, 0.17-1.17, P=0.101). Using the alkaline hematin test, the reduction of MBL was significantly greater in the LNG-IUS group (90.9% ± 12.8% vs 13.4% ± 11.1%; P<0.001). Using PBAC scores, the reduction was also significantly greater in the LNG-IUS group (88.0% ± 16.5% vs 53.5% ± 5 1.2%; P=0.02). Moreover, hemoglobin levels increased from 9.7 ± 1.9g/dL to 11.7 ± 1.2g/dL (P<0.001) and lost days decreased from 8.2 ± 3.3 days to 1.3 ± 1.5 days (P=0.003) in the LNG-IUS group.

CONCLUSION

Although the rate of treatment failure was similar in both groups, the LNG-IUS was more effective in reducing MBL than the COC in women with fibroid-related menorrhagia.

Acceptability of the levonorgestrel intrauterine system in the long-term treatment of heavy menstrual bleeding: how many women choose to use a second device?

OBJECTIVE

To assess the acceptability of the levonorgestrel-releasing intrauterine system (LNG-IUS, Mirena®) in the long-term treatment of heavy menstrual bleeding.

STUDY DESIGN

Retrospective study of all consecutive women who had a LNG-IUS inserted for control of idiopathic heavy menstrual bleeding between January 2000 and December 2003. Duration of use, reasons for early removal, number of devices removed after 5 years of use, and number of women who decided to use a second LNG-IUS were assessed.

RESULTS

Of a total of 216 devices inserted, 129 (59.7%) were removed after 5 years of use, 68 (31.5%) were removed anytime before the completion of 5 years, and the remaining 19 (8.8%) patients were lost to follow-up. In 32 of the 68 cases (47.1%) with early removal of the LNG-IUS, the main reason for discontinuation was the appearance of the menopause. After the 5-year effective lifetime of the LNG-IUS, 51 of the 129 women (39.5%) chose to have a second device inserted. Of the 78 women who completed the 5-year treatment period and did not decide to use the LNG-IUS again, 71 (91%) had reached the menopause.

CONCLUSION

The LNG-IUS was well accepted by women with idiopathic heavy menstrual bleeding as shown by 39.5% of users (or 87.9% if menopausal women are excluded) deciding to use a second device when the first LNG-IUS expired after 5 years of use.

Hysterectomy, endometrial destruction, and levonorgestrel releasing intrauterine system (Mirena) for heavy menstrual bleeding: systematic review and meta-analysis of data from individual patients

OBJECTIVE

To evaluate the relative effectiveness of hysterectomy, endometrial destruction (both "first generation" hysteroscopic and "second generation" non-hysteroscopic techniques), and the levonorgestrel releasing intrauterine system (Mirena) in the treatment of heavy menstrual bleeding.

DESIGN

Meta-analysis of data from individual patients, with direct and indirect comparisons made on the primary outcome measure of patients' dissatisfaction.

DATA SOURCES

Data were sought from the 30 randomised controlled trials identified after a comprehensive search of the Cochrane Library, Medline, Embase, and CINAHL databases, reference lists, and contact with experts. Raw data were available from 2814 women randomised into 17 trials (seven trials including 1359 women for first v second generation endometrial destruction; six trials including 1042 women for hysterectomy v first generation endometrial destruction; one trial including 236 women for hysterectomy v Mirena; three trials including 177 women for second generation endometrial destruction v Mirena). Eligibility criteria for selecting studies Randomised controlled trials comparing hysterectomy, first and second generation endometrial destruction, and Mirena for women with heavy menstrual bleeding unresponsive to other medical treatment.

RESULTS

At around 12 months, more women were dissatisfied with outcome with first generation hysteroscopic techniques than with hysterectomy (13% v 5%; odds ratio 2.46, 95% confidence interval 1.54 to 3.9, P<0.001), but hospital stay (weighted mean difference 3.0 days, 2.9 to 3.1 days, P<0.001) and time to resumption of normal activities (5.2 days, 4.7 to 5.7 days, P<0.001) were longer for hysterectomy. Unsatisfactory outcomes were comparable with first and second generation techniques (odds ratio 1.2, 0.9 to 1.6, P=0.2), although second generation techniques were quicker (weighted mean difference 14.5 minutes, 13.7 to 15.3 minutes, P<0.001) and women recovered sooner (0.48 days, 0.20 to 0.75 days, P<0.001), with fewer procedural complications. Indirect comparison suggested more unsatisfactory outcomes with second generation techniques than with hysterectomy (11% v 5%; odds ratio 2.3, 1.3 to 4.2, P=0.006). Similar estimates were seen when Mirena was indirectly compared with hysterectomy (17% v 5%; odds ratio 2.2, 0.9 to 5.3, P=0.07), although this comparison lacked power because of the limited amount of data available for analysis.

CONCLUSIONS

More women are dissatisfied after endometrial destruction than after hysterectomy. Dissatisfaction rates are low after all treatments, and hysterectomy is associated with increased length of stay in hospital and a longer recovery period. Definitive evidence on effectiveness of Mirena compared with more invasive procedures is lacking.

Clinical practice guidelines on menorrhagia: management of abnormal uterine bleeding before menopause

BACKGROUND

Normal menstrual periods last 3-6 days and involve blood loss of up to 80ml. Menorrhagia is defined as menstrual periods lasting more than 7 days and/or involving blood loss greater than 80ml. The prevalence of abnormal uterine bleeding (AUB) is estimated at 11-13% in the general population and increases with age, reaching 24% in those aged 36-40 years.

INVESTIGATION

A blood count for red cells+platelets to test for anemia is recommended on a first-line basis for women consulting for AUB whose history and/or bleeding score justify it. A pregnancy test by an hCG assay should be ordered. A speculum examination and Pap smear, according to the French High Health Authority guidelines should be performed early on to rule out any cervical disease. Pelvic ultrasound, both abdominal (suprapubic) and transvaginal, is recommended as a first-line procedure for the etiological diagnosis of AUB. Hysteroscopy or hysterosonography can be suggested as a second-line procedure. MRI is not recommended as a first-line procedure.

TREATMENT

In idiopathic AUB, the first-line treatment is medical, with efficacy ranked as follows: levonorgestrel IUD, tranexamic acid, oral contraceptives, either estrogens and progestins or synthetic progestins only, 21 days a month, or NSAIDs. When hormone treatment is contraindicated or immediate pregnancy is desired, tranexamic acid is indicated. Iron must be included for patients with iron-deficiency anemia. For women who do not wish to become pregnant in the future and who have idiopathic AUB, the long-term efficacy of conservative surgical treatment is greater than that of oral medical treatment. Placement of a levonorgestrel IUD (or administration of tranexamic acid by default) is recommended for women with idiopathic AUB. If this fails, a conservative surgical technique must be proposed; the choices include second-generation endometrial ablation techniques (thermal balloon, microwave, radiofrequency), or, if necessary, first-generation techniques (endometrectomy, roller-ball). A first-line hysterectomy is not recommended in this context. Should a hysterectomy be selected for functional bleeding, it should be performed by the vaginal or laparoscopic routes.

New directions in the epidemiology of uterine fibroids

Although uterine leiomyomata (fibroids) have been the leading indication for hysterectomy in the United States for decades, the epidemiological data on fibroid prevalence and risk factors are limited. Given the hormonal dependence of fibroids, most earlier studies focused on reproductive or hormonal factors. Recent analyses have extended that focus to other areas. We present previously unpublished data on the association between reproductive tract infections and fibroids that highlight the need for more detailed studies. Our review suggests that metabolic, dietary, stress, and environmental factors may also play a role in fibroid development.
