RESUMO

OBJECTIVES: This study aimed to determine the proportion of participants whose uterine bleeding/spotting was interrupted for at least 7 days during the month after they received a combined hormonal injection. We also evaluated bleeding at 21 days and 12 weeks after the injection. STUDY DESIGN: We conducted a randomized, double-blind, placebo-controlled trial in 46 contraceptive implant users who presented with bothersome uterine bleeding/spotting. A single dose of a combination injectable contraceptive or placebo was administered intramuscularly at enrollment. RESULTS: The proportions of participants whose uterine bleeding/spotting was interrupted for at least 7 days the month after they received a combined hormonal injection were higher in the combination injectable contraception group than in the placebo group (87% vs 48%, p = 0.005). Participants who reported that they were bleeding free at 21 days after treatment were 52% and 35% in the combination injectable contraception group and placebo group, respectively (p = 0.24). At 12 weeks posttreatment, 17% of participants in the combination injectable contraception group and 4% in the placebo group reported cessation of bleeding with no recurrence (p = 0.34). The median days until the first bleeding interruption was shorter in the combination injectable contraception group compared with the placebo group (1 [interquartile range, 1-2] vs 8 [interquartile range, 1-28], p = 0.007). CONCLUSIONS: The combination injectable contraception interrupted bothersome uterine bleeding/spotting in contraceptive implant(s) users compared with placebo. However, this effect was limited only within the month when the treatment was administered. IMPLICATIONS: Bothersome uterine bleeding/spotting is a common side effect leading to contraceptive implant(s) discontinuation. In implant users experiencing these symptoms with no estrogen contraindications, a combined injectable contraception appears to rapidly improve bleeding for the duration of injectable exposure (1 month).

RESUMO

BACKGROUND: abnormal uterine bleeding is a very frequent reason for referral to gynaecologists and can deeply influence the quality of life. Once organic causes requiring surgical treatment are ruled out, clinicians should be able to manage these patients conservatively in the most effective way. MATERIALS AND METHODS: a search in PubMed/MEDLINE database was conducted in order to find relevant and recent meaningful sources for this narrative review. RESULTS: LNG-IUS 52 mg is the first-line treatment for non-organic causes. Nevertheless, it could be contraindicated or declined by the patient. Combined oral contraceptives (COC) and progestin-only pills inhibit the hypothalamic-pituitary-ovarian axis, preventing ovulation, and induce endometrial atrophy. Consequently, they are effective in treating AUB. Moreover, brand new pills containing a combination of oestrogens, progestins and GnRH antagonists are now available for the management of AUB related to uterine fibroids. CONCLUSIONS: In daily clinical practice, oral hormonal therapies are convenient and reversible tools to manage AUB when LNG-IUS 52 mg is contraindicated or turn down by the patient. Many oral hormonal therapies are prescribed to treat AUB, but only a few have been approved with this specific indication, therefore further large well-designed studies are necessary in order to compare the efficacy of different pills for treating AUB.


Even though LNG-IUS 52 mg is the first-line treatment for abnormal uterine bleeding, oral hormonal therapies should be effectively managed by gynaecologists in case of contraindications or patient's decline. Contraceptive pills are practical, but further studies are necessary to compare their efficacy and to approve them with the specific AUB indication.

RESUMO

BACKGROUND: In the pivotal LIBERTY 1 and 2 trials and long-term extension study, once-daily relugolix combination therapy (40 mg relugolix, 1 mg estradiol, 0.5 mg norethindrone acetate) reduced menstrual blood loss volume and pain among women with uterine fibroids. Relugolix combination therapy was well tolerated with preservation of bone mineral density through 52 weeks. OBJECTIVE: This study aimed to report the 2-year relugolix combination therapy efficacy and safety results of the phase 3 LIBERTY randomized withdrawal study. STUDY DESIGN: Women with uterine fibroid-associated heavy menstrual bleeding who completed the 24-week LIBERTY 1 or 2 trials, followed by the 28-week long-term extension study (up to 52 weeks total treatment), and who met the responder criteria (menstrual blood loss volume <80 mL and ≥50% reduction from pivotal study baseline at week 48 [week 24 of long-term extension]) were randomized in a 1:1 ratio to either blinded treatment with relugolix combination therapy or placebo for 52 weeks (total treatment period, 104 weeks). For women who had a relapse of heavy menstrual bleeding during the study (menstrual blood loss volume ≥80 mL), open-label relugolix combination therapy was offered. The primary endpoint was the proportion of women who maintained menstrual blood loss volume <80 mL through week 76 (week 24 of randomized withdrawal study). Secondary endpoints included time to menstrual blood loss volume ≥80 mL, proportion of women who maintained a menstrual blood loss volume of <80 mL through week 104 (over the 52-week randomized treatment period), the proportion of women who achieved or maintained amenorrhea at week 76 at the end of treatment, and the change in Uterine Fibroid Symptom-Quality of Life Bleeding and Pelvic Discomfort Scale and symptom severity scores. Analyses were performed for the modified intent-to-treat population, including all randomized women who received ≥1 dose of the study drug. RESULTS: Of the 229 randomized women (relugolix combination therapy, n=115; placebo, n=114), 228 received the study drug and 175 (76.7%) completed the randomized withdrawal study. Through week 76, 78.4% of women on relugolix combination therapy maintained menstrual blood loss volume <80 mL vs 15.1% in the placebo group (difference, 63.4%; 95% confidence interval, 52.9%-73.9%; P<.0001). At week 104, 69.8% of women on relugolix combination therapy maintained menstrual blood loss volume <80 mL vs 11.8% in the placebo group (difference, 58.0%; 95% confidence interval, 47.0%-69.1%; P<.0001). Through week 104, 88.3% of women on placebo relapsed with heavy menstrual bleeding (median time to relapse, 5.9 weeks). Among the 89 women in the placebo group who relapsed and received open-label rescue treatment, 87 women responded to relugolix combination therapy with a menstrual blood loss volume <80 mL. The proportion of women who achieved or maintained amenorrhea were 57.4% vs 13.3% at week 76 (difference, 44.1%; 95% confidence interval, 33.10%-55.1%; P<.0001) and 58.3% vs 10.6% at week 104 (difference, 47.6%; 95% confidence interval, 37.0%-58.3%; nominal P<.0001) for relugolix combination therapy and the placebo group, respectively. Relugolix combination therapy was generally well tolerated; no new safety signals were identified, and the adverse event profile over the second year was consistent with that reported through the first year of treatment. Bone mineral density remained stable in women who received relugolix combination therapy from week 52 to week 104. In women continuously treated with relugolix combination therapy up to 2 years, bone mineral density was generally preserved. CONCLUSION: After 2 years of treatment with relugolix combination therapy, there was evidence of durability of the effect in maintaining low menstrual blood loss volume in women with symptomatic uterine fibroids. Most women had return of heavy menstrual bleeding and associated symptoms after treatment cessation, which improved upon retreatment with relugolix combination therapy. Relugolix combination therapy was well tolerated, the adverse event profile remained consistent, and the mean bone mineral density was generally preserved through 2 years of treatment.

RESUMO

OBJECTIVE: To assess the clinical characteristics and endocrinological background of women with vascular retained products of conception (RPOC) after miscarriage or abortion and evaluate the effect of estrogen-progestogen therapy (EPT) as an initial treatment on this population based on their endocrinological background. MATERIALS AND METHODS: Women with vascular RPOC after miscarriage or abortion at less than 20 weeks of pregnancy who were given EPT (conjugated estrogen and norethisterone) were retrospectively reviewed. Their clinical characteristics, hormonal parameters, ultrasonographic findings, and outcomes were evaluated. RESULTS: Of 35 women with vascular RPOC, 30 (86%) presented with vaginal bleeding at a visit, and 6 (17%) required inpatient management due to heavy bleeding. Among women who presented with vaginal bleeding, serum progesterone levels were significantly lower (0.25 vs. 6.5 ng/mL, p = 0.004) than those in women who did not present with vaginal bleeding. There were no differences in serum hCG levels (10.5 vs. 3.1 mIU/mL) or serum estradiol levels (65.4 vs. 162.3 pg/mL). After withdrawal bleeding following the first course of EPT, vaginal bleeding was stopped in 27 of the 30 women (90%), and 23 (66%) of all women had a thin and linear endometrium. All women could be treated by up to two courses of EPT and did not require additional interventions. The median duration to hCG normalization after the initial EPT was 24.5 (9-88) days. CONCLUSION: Women with vascular RPOC who have no bleeding had significantly higher levels of serum progesterone, indicating that administration of progestogen may have an effect on hemostasis. Endometrial bleeding can be prevented or stopped, and retained tissues can be conservatively expelled by oral administration of EPT, including norethisterone, in women with vascular RPOC.

RESUMO

O presente estudo tem como objetivo relatar o caso de uma paciente com malformação arteriovenosa uterina, efetivamente tratada com embolização seletiva e com fertilidade preservada. A malformação arteriovenosa uterina é uma alteração vascular rara até então pouco descrita na literatura. A paciente do sexo feminino apresentou quadro de sangramento uterino anormal, com início 30 dias após um abortamento, sem realização de curetagem, de uma gestação resultante de fertilização in vitro. Foram, então, realizados exames de imagem, que levaram ao diagnóstico de malformação arteriovenosa uterina. O tratamento de escolha foi a embolização arterial seletiva, com resolução do caso. Após sete meses, nova fertilização in vitro foi realizada, encontrando-se na 36a semana de gestação. São necessários mais estudos sobre essa malformação a fim de que sejam estabelecidos os métodos mais eficazes para o manejo de casos futuros, especialmente quando há desejo de gestar.


The present study aims to report the case of a patient with uterine arteriovenous malformation, effectively treated with selective embolization and with preserved fertility. Uterine arteriovenous malformation is a rare vascular disorder that has so far been rarely described in the literature. Female patient presented with abnormal uterine bleeding, starting 30 days after an abortion without subsequent curettage, of a pregnancy resulting from in vitro fertilization. Imaging tests were then performed that led to the diagnosis of uterine arteriovenous malformation. The treatment of choice was selective arterial embolization, with successful results. After seven months, a new in vitro fertilization was performed, being in the 36th week of pregnancy. Further studies on this pathology are needed in order to establish the most effective methods for the management of future cases, especially when there is a desire to become pregnant.

RESUMO

BACKGROUND: Abnormal uterine bleeding (AUB), which includes heavy menstrual bleeding (HMB), is a common condition placing women at increased risk for developing iron deficiency and iron deficiency anemia (IDA). Depletion of iron stores has negative implications on physical, social, and emotional health, as well as quality of life. Iron supplements are safe, effective, and readily available, while red blood cell (RBC) transfusions have inherent risks including infectious and immune reactions. Despite high prevalence of IDA among women with AUB, there are limited studies on the impact of iron therapies on patient outcomes. This systematic review and meta-analysis will evaluate the impact of iron supplementation on patient outcomes for women with AUB, when compared to combination therapy, no intervention, placebo, or standard of care. METHODS: We will conduct a systematic review and meta-analysis of randomized controlled trials and observational studies evaluating the impact of iron interventions on patient outcomes for women with AUB. Systematic literature searches will be conducted in major databases including MEDLINE, EMBASE, CENTRAL, CINAHL, and Web of Science. Studies assessing the impact of iron interventions on patient outcomes in women experiencing AUB, in comparison to combination therapy, no intervention, placebo, or standard of care, will be included in the review. Independent reviewers will screen for eligibility, assess risk of bias, and abstract data. Overall certainty of evidence for each outcome will be assessed using the GRADE approach. We will meta-analyze outcomes which are sufficiently homogeneous to summarize intervention effects and narratively synthesize nonhomogeneous outcomes. The main outcomes of interest are hemoglobin levels immediately prior to surgery and post-operatively, number of RBC transfusions, and adverse effects. Secondary outcomes will include length of hospital stay, intraoperative blood loss, adverse and side effects, quality of life, and iron indices. DISCUSSION: This review will evaluate the impact of iron interventions on patient outcomes in women with IDA secondary to AUB with focus on changes in hematological and iron indices, red blood cell utilization, quality of life, cost of treatment, and adverse events. The results will inform evidence-based clinical practice for the management of iron deficiency and IDA secondary to AUB. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019137282.

RESUMO

STUDY OBJECTIVE: Incidence of abnormal uterine bleeding (AUB) during pubertal induction among individuals with Turner syndrome (TS) has not been described previously. We estimated the incidence and characterized factors associated with AUB among individuals with TS. A secondary objective was to evaluate the management of AUB among this patient population. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTION: We conducted a retrospective chart review to evaluate individuals with TS undergoing hormone replacement therapy (HRT) for pubertal induction with transdermal estrogen. A total of 45 participants were identified between January 2007 and June 2019. RESULTS: Of the 45 individuals with TS included, 16 (35%) experienced AUB. Individuals with AUB most commonly experienced prolonged (44%), prolonged and heavy (25%), and intermenstrual (19%) bleeding. Individuals who experienced AUB were more likely to experience spontaneous bleeding (69% vs 28%) and a duration of unopposed estrogen greater than 18 months (63% vs 41%), undergo progestin cycling less often than monthly (69% vs 0%), use a micronized progestin dose of less than 200 mg (25% vs 14%), and be noncompliant with HRT (19% vs 0%) compared with those who did not experience AUB. CONCLUSION: There is a relatively high incidence of AUB among individuals with TS undergoing pubertal induction with transdermal estrogen. Care providers should consider the clinical factors examined to guide monitoring and management of individuals with TS on HRT.

RESUMO

Background and objectives: Abnormal uterine bleeding is a significant clinical and gynaecological concern that necessitates its safe and effective treatment. The present study aims to compare the cost-effectiveness, safety, efficacy, and health-related quality of life of ormeloxifene with medroxyprogesterone acetate in women with non-structural abnormal uterine bleeding. Materials and Methods: A prospective, randomized, single-blinded clinical trial of 367 patients was carried out at a tertiary care hospital for a period of one year from 5 January 2019 to 4 January 2020. Patients were randomized into two groups for administering ormeloxifene and medroxyprogesterone acetate for a 3-month treatment duration and were evaluated by laboratorial investigations like anaemic status, bleeding duration, endometrial thickness, pictorial blood loss assessment chart (PBLAC) score, and patient's medical and medication history. Health-related quality of life was assessed using short form survey-36 (SF-36) questionnaire scale. Cost-effectiveness was determined on the basis of the three-month treatment regimen. Results: The mean duration of bleeding reduced from 16.88 ± 6.46 to 7.76 ± 1.55 in the ormeloxifene group and from 15.91 ± 5.04 to 8.7 ± 1.91 (p < 0.001) in the medroxyprogesterone acetate. Similarly, mean haemoglobin increased from 8.56 ± 0.77 to 10.1 ± 0.087 g/dL and from 8.60 ±0.97 to 9.551 ± 0.90 g/dL (p < 0.001), and endometrial thickness showed a reduction from 8.52 ± 1.61 mm to 6.92 ± 1.68 mm and from 8.40 ± 2.09 mm to 7.85 ± 2.0 mm (p < 0.001) in the ormeloxifene and medroxyprogesterone acetate groups, respectively. PBLAC score reduced from 289.92 ± 42.39 to 128.11 ± 33.10 and from 287.38 ± 40.94 to 123.5 ± 29.57 (p < 0.001) in these groups, respectively. Health-related quality of life improved in the ormeloxifene group more than the medroxyprogesterone group, which was evidenced by SF-36 scale parameters (physical function, energy/fatigue and pain) that changed from 24.39, 12.99, 6.25 to 28.95, 18, 9 and from 25.41, 13.6, 7.1 to 27.02, 16, 8.3 in the ormeloxifene and medroxyprogesterone acetate groups, respectively. Conclusions: The study concludes that both medroxyprogesterone acetate and ormeloxifene are safe and efficacious in controlling abnormal uterine bleeding, but ormeloxifene was the better of the two in terms of cost effectiveness, reduction in pictorial blood loss assessment score, endometrial thickness, bleeding duration (days), increase in haemoglobin concentration (g/dL) and improvement in the quality of life.

RESUMO

OBJECTIVE: The aim of our study was to evaluate the effects of the LNG-IUS on uterine volume, bleeding patterns, and LNG-IUS-related outcomes among women using the device to treat abnormal uterine bleeding caused by fibroids, adenomyosis, HMB (without structural cause), or contraception. STUDY DESIGN: This was a 5-year cohort study with LNG-IUS users. We selected 147 women, who were allocated to four groups: a) control (contraception indication); b) fibroids; c) adenomyosis; d) HMB. The visits for clinical and ultrasound evaluations were made at baseline and at 3, 6, 12, 24, 36, 48, and 60 months postinsertion. All data are expressed as mean and standard deviation (SD) or absolute and relative (%) frequency. Differences among groups were established by using the χ2 (chi-square) test and Fisher's exact tests for categorical outcomes, as well as the Mann-Whitney and the Kruskal-Wallis tests and Friedman's ANOVA for continuous variables. We used the 5% significance level as an indication of statistical significance. Logistic regression analyses were performed to study the association between predictors and outcomes. Results are expressed as odds ratios (ORs) with a 95% confidence interval (CI 95%). RESULTS: Although all groups had real rates of bleeding patterns, troublesome bleeding appeared to be more frequent in the fibroid group (∼15%). Also, along the 60 months of follow-up, uterine volume slightly decreased in the groups of HMB, adenomyosis, and fibroids, but not in the contraception group. However, the isolated volume of fibroids remained unchanged. In this cohort, we observed high continuation rates among LNG-IUS users. The uterine volume ≥200 cm3 was the main predictor of hysterectomy or IUS expulsion in the adenomyosis and fibroid groups. CONCLUSION: The LNG-IUS may control uterine menstrual bleeding as well as uterine volume in adenomyosis, fibroids, and HMB. An initial uterine volume smaller than 200 cm3 is an important predictor of adherence to treatment and better outcomes.

RESUMO

This study aimed to investigate the effect of Tiaojingzhixue decoction on the expression of sex hormone and endometrial mRNA in perimenopausal patients with abnormal uterine bleeding. For this purpose, 84 patients with perimenopausal abnormal uterine bleeding who were treated in our hospital from January 2018 to January 2019 were divided into study group and control group, the control group was treated with mifepristone for six months, the clinical efficacy, time of symptom relief and disappearance, endometrial thickness, menstrual volume, adverse events, expression of sex hormone (ER), Progesterone receptor (PR), Lutropin (LH), Follicle-stimulating hormone (FSH), Estradiol (e2) and Vascular endothelial growth factor in endometrial tissue were compared between the two groups. The results showed that the clinical efficacy of the study group (97.61%) was significantly higher than the control group (80.95%) (P<0.05). There was no significant difference in endometrial thickness between the two groups before treatment, but after treatment for 1 month, 3 months and 6 months, endometrial thickness was thinner in the study group (P<0.05). There was no significant difference in menstrual volume between the two groups before treatment (P <0.05), but it was lower in the study group (P <0.05). The incidence of adverse reactions in the study group was 11.90% lower than in the control group (26.19%). The expression levels of ER, PR, LH, FSH and E2 were almost the same before treatment and there was no significant difference between the two groups (P>0.05), but they were lower in the study group after treatment (P<0.05). Before treatment, there was no significant difference in the level of VEGF between the two groups (P>0.05); after treatment, the level of Vegf in the study group was lower than the control group (P<0.05). After treatment, the level of Vegf in both groups was significantly higher than before treatment (P<0.05). In general, Tiaojingzhixue decoction can decrease the level of sex hormone and increase the expression of VEGF in patients with perimenopausal abnormal uterine bleeding.

RESUMO

This study aims to explore the anti-inflammatory and hemostatic effects of the total extract of Clinopodium chinense(TEC), total saponins of C. chinense(TSC), and total flavonoids of C. chinense(TFC) in female rats with abnormal uterine bleeding(AUB), and the possible mechanism. Mifepristone(i.g., 12.4 mg·kg~(-1)) and misoprostol(i.g., 130 µg·kg~(-1)) were used to induce AUB in SD female rats conceiving on the same day. Then the AUB rats were randomized into model group, TEC group, TSC group, TFC group, Yimucao Granules(LG) group, and estradiol valerate(EV) group, with 8 rats in each group. Another 8 non-pregnant female rats were selected as normal group. During the experiment, each group was given the corresponding drug by gavage once a day for 7 days. After the administration, blood and uterine tissue were collected. The uterine bleeding volume was measured by ultraviolet spectrophotometry and the pathological changes of endometrium were observed based on hematoxylin-eosin(HE) staining. In addition, the microvessel density of endometrium was determined by immunohistochemistry, and the content of thromboxane B2(TXB2), 6-keto-PGF_(1α), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) in plasma and levels of lutenizing hormone(LH), follicle stimulating hormone(FSH), estradiol(E_2), and progesterone in serum were detected by enzyme-linked immunosorbent assay(ELISA). The mRNA and protein expression of estrogenreceptor α(ERα), progesterone receptor(PR), matrix metalloproteinase(MMP)-2, MMP-9, and vascular endothelial growth factor(VEGF) in uterine tissue was determined by Western blot. Compared with the model group, TEC, TSC, and TFC can reduce uterine bleeding volume, alleviate the pathological damage of endometrium, and increase the microvessel density in endometrium. Moreover, TEC and TSC can significantly raise plasma TXB2 level and ratio of TXB2 to 6-keto-PGF_(1α), and TEC and TFC can significantly reduce the levels of IL-6 and TNF-α. In addition, TEC significantly elevated serum progesterone level and TFC significantly increased serum levels of E_2, FSH, and LH. TSC can significantly raise serum progesterone and FSH levels. In addition, TEC can significantly down-regulate the protein expression of PR, MMP-2, and VEGF and TSC significantly reduced the expression of MMP-9. TFC significantly decreased the expression of PR, MMP-9, and VEGF, and up-regulated the expression of ERα. In conclusion, TEC, TSC, and TFC all show therapeutic effects on AUB, particularly TEC. TSC exerts the effects by enhancing the coagulation function and promoting endometrial repair, and TFC by regulating estrogen levels and reducing inflammatory response. This study reveals the mechanism of C. chinense against AUB and also explains the holistic characteristics of Chinese medicine.

RESUMO

BACKGROUND: Progesterone is widely used to improve the adverse pregnancy outcomes related to vaginal bleeding during early pregnancy. However, the evidence of its effectiveness is equivocal. METHODS: Six thousand six hundred fifteen mother-infant pairs from Tongji Maternal and Child Health Cohort (TMCHC) were involved in the study. Information on vaginal bleeding, progesterone administration in early pregnancy were obtained at enrolment. Birth outcomes were obtained from the hospital notes. Body weight of the infants at 12 months of age was collected by telephone interview. Multivariable logistic regression was conducted to estimate the effect of vaginal bleeding and progesterone administration in early pregnancy on birth outcomes and weight status of infants at 12 months of age. RESULTS: 21.4% (1418/6615) participants experienced bleeding in early pregnancy, and 47.5% (674/1418) of them were treated with progesterone. There were no significant associations between progesterone supplementation in early pregnancy and offspring outcomes. Compared to women without bleeding or any therapy, women with bleeding and progesterone therapy experienced increased risk of preterm (OR 1.74, 95% CI 1.21-2.52), and delivering a small-for-gestational-age (SGA) (OR 1.46, 95% CI 1.07-1.98) or low birth weight (LBW) (OR 2.10, 95% CI 1.25-3.51) neonate, and offspring of them had an increased risk of weight for age z-score (WAZ) < -1 at 12 months of age (OR 1.79, 95%CI 1.01-3.19). CONCLUSIONS: Offspring of mothers with bleeding and progesterone therapy were more likely to be a premature, SGA or LBW neonate, and had lower weight at 12 months of age. Progesterone supplementation may have no beneficial effect on improving adverse offspring outcomes related to early vaginal bleeding. TRIAL REGISTRATION: TMCHC was registered at clinicaltrials.gov as NCT03099837 on 4 April 2017.

RESUMO

Women with chronic abnormal uterine bleeding-ovulatory dysfunction (AUB-O) are at increased risk of endometrial neoplasia. We conducted a non-inferiority randomized controlled trial to determine the effectiveness of two cyclic-progestin regimens orally administered 10 d/month for 6 months on endometrial protection and menstruation normalization in women with AUB-O. There were 104 premenopausal women with AUB-O randomized to desogestrel (DSG 150 µg/d, n = 50) or medroxyprogesterone acetate (MPA 10 mg/d, n = 54) group. Both groups were comparable in age (44.8 ± 5.7 vs. 42.5 ± 7.1 years), body mass index (24.8 ± 4.7 vs. 24.9 ± 4.7 kg/m2), and AUB characteristics (100% irregular periods). The primary outcome was endometrial response rate (the proportion of patients having complete pseudodecidualization in endometrial biopsies during treatment cycle-1). The secondary outcome was clinical response rate (the proportion of progestin withdrawal bleeding episodes with acceptable bleeding characteristics during treatment cycle-2 to cycle-6). DSG was not inferior to MPA regarding the endometrial protection (endometrial response rate of 78.0% vs. 70.4%, 95% CI of difference - 9.1-24.4%, non-inferiority limit of - 10%), but it was less effective regarding the menstruation normalization (acceptable bleeding rate of 90.0% vs 96.6%, P = 0.016).Clinical trial registration: ClinicalTrials.gov (NCT02103764, date of approval 18 Feb 2014).

RESUMO

OBJECTIVE: The aim of this systematic review is to gather and synthesize evidence regarding the use of oral gonadotrophin-releasing hormone (GnRH) antagonist for the treatment of bleeding associated with uterine myomas. DATA SOURCES: Web of Science, and MEDLINE databases were searched electronically on March 5, 2021, using combinations of the relevant Medical Subject Headings terms and keywords. The search was restricted to the English language and to human studies. METHODS OF STUDY SELECTION: Only randomized controlled trials involving patients with heavy menstrual bleeding associated with uterine myomas treated with different doses of oral nonpeptide GnRH antagonists with or without add-back therapy were included. Studies comparing oral nonpeptide GnRH antagonists with treatments other than placebo were also excluded. TABULATION, INTEGRATION, AND RESULTS: A total of 5 randomized trials including 2463 women were included in the analyses. Included studies were found to be at low risk of bias. When treatments were compared against placebo, the top 3 treatments for bleeding suppression were elagolix 600 mg, 400 mg, and 200 mg without add-back. Elagolix 600 mg without add-back therapy had a significantly higher risk of amenorrhea than lower doses of elagolix with and without add-back and relugolix as well. Uterine volume changes were more pronounced in therapies without add-back. All treatments were associated with significantly improved quality of life scores, both for myoma symptom-related and overall health-related scores. With the exception of relugolix with high-dose add-back, all treatments significantly increased low-density lipoprotein (LDL) levels. Again, all treatment modalities except for elagolix 200 mg without add-back significantly increased LDL-to-HDL ratio. The increase was highest for treatment without add-back therapy. CONCLUSION: Oral GnRH antagonists seem to be effective for myoma-associated bleeding and for improving quality of life. The safety profile is acceptable for short-term use, but lipid metabolism is affected.

RESUMO

CONTEXT: Large-scale clinical trials on the hepatotoxicity of ulipristal acetate (UPA) are lacking. OBJECTIVE: This work aimed to determine the incidence of liver disease with UPA vs gonadotropin-releasing hormone (GnRH) agonists. METHODS: A retrospective cohort study was conducted in South Korea of women with uterine fibroids from the Korean Health Insurance Data 2010 to 2018. Women with uterine fibroids were divided into 2 treatment groups: the UPA (5 mg/day) and GnRH agonist groups. Main outcome measures included the presence or absence of severe liver disease, mild liver disease, and liver transplantation. RESULTS: Among the patients with uterine fibroids,17 207 patients were treated with GnRH agonists and 20 926 patients with UPA. After 1:1 propensity score matching for each group, there were 11 445 individuals. Neither group had a liver transplantation case. In the conditional logistic regression analysis, the incidence of total liver diseases (relative risk [RR] 1.111; 95% CI, 1.015-1.216) and mild liver diseases (RR 1.094; 95% CI, 1-1.196) was higher in the UPA group than in the GnRH agonist group, but that of severe liver diseases (RR 0.07; 95% CI, 0.001-4.412) and toxic liver disease (RR 1.256; 95% CI, 0.845-1.867) did not differ between the groups. CONCLUSION: The incidence of severe liver disease, hepatic failure, and toxic liver disease was not different between the UPA and GnRH agonist groups. However, the incidence of mild liver disease was higher in the UPA group than in the GnRH agonist group. The incidence of hepatic damage with UPA was very low.

RESUMO

OBJECTIVE: To compare the efficacy and safety of dienogest with combined oral contraceptives (COCs) for treating adenomyosis-associated symptoms. METHODS: This was a randomized clinical trial including women with symptomatic adenomyosis conducted from March 1, 2019 to August 1, 2020 at Assiut Woman's Health Hospital, Egypt. Participants were randomly assigned to the dienogest group or COCs group. The primary outcome was the level of adenomyosis-associated pain from before to 6 months after treatment measured by a visual analog scale (VAS). Changes in the uterine bleeding pattern, uterine volume, and uterine artery blood flow were also reported. RESULTS: The VAS score of pain was significantly decreased in both groups; however, the decreased rate was more pronounced in the dienogest group (3.21 ± 1.18) in comparison with the COCs group (4.92 ± 1.22). Bleeding pattern was improved greatly; uterine volume and uterine artery blood flow decreased significantly in the dienogest group. However, women in the dienogest group reported a higher rate of side effects. CONCLUSION: Dienogest and COCs are effective in treating adenomyosis-associated symptoms after 6 months of use but dienogest is more effective. The decrease in uterine volume and uterine artery blood flow may be the cause of the treatment effect. Dienogest carries a higher risk of side effects. CLINICAL TRIAL: gov: NCT03890042.

RESUMO

PURPOSE: This case report aimed to describe haemostatic agents with systemic methotrexate (MTX) as an effective management for cervical pregnancy with bleeding. CASE PRESENTATION: A 34-year-old nulligravida patient was referred due to vaginal spotting and lower abdominal discomfort, and was diagnosed with a cervical pregnancy at 6 weeks of gestation. The patient was treated with a multi-dose MTX regimen, and the bleeding was successfully controlled with haemostatic agents, which were applied at the bleeding site of the cervix. After completion of MTX treatment, beta human chorionic gonadotropin (ß-hCG) decreased to undetectable range. Furthermore, patients could preserve her uterus and maintain fertility. CONCLUSION: Haemostatic agents can be regarded as an effective option for vaginal bleeding due to cervical pregnancy.

RESUMO

OBJECTIVE: To evaluate symptomatic uterine fibroid outcomes following at least one course of ulipristal acetate (UPA) 5 mg/day therapy in the hospital setting, during the year 2017. STUDY DESIGN: A retrospective and descriptive analysis involving women with symptomatic fibroids was conducted in 15 hospital centers in Portugal in 2017 to assess fibroid size, bleeding control and hemoglobin levels following at least one course of UPA 5 mg/day. Secondary outcomes were the reasons for the treatment, type of surgery, fibroid classification, patient satisfaction with the treatment, and adverse events. RESULTS: Five-hundred and twenty-six patients were enrolled in this survey, and 93 % of the women completed, at least, 1 treatment course with UPA. Uterine bleeding control was achieved in 81 % of the cases. A significant increase (p < 0.001) in hemoglobin levels and a reduction (p < 0.001) in uterine fibroid size was observed after treatment, with a median reduction of 24 % from the baseline. Forty-seven percent of the patients underwent subsequent surgery and there were no serious adverse events reported in this multicentric nationwide study. CONCLUSIONS: So far, this is the largest case series reporting on symptomatic uterine fibroid outcomes after UPA therapy in Portugal. Our data are in line with published literature and confirm favorable outcomes after UPA therapy for women of childbearing age and premenopausal.

RESUMO

OBJECTIVE: To evaluate whether a short course of tamoxifen decreases bothersome bleeding in etonogestrel contraceptive implant users. METHODS: In a 90-day, double-blind randomized control trial, we enrolled etonogestrel implant users with frequent or prolonged bleeding or spotting. A sample size of 40 per group (N=80) was planned to compare 10 mg tamoxifen or placebo twice daily for 7 days after 3 consecutive days of bleeding or spotting no more than once per 30 days (maximum three treatments). Participants then entered a 90-day open-label study where all received tamoxifen if needed every 30 days (maximum three treatments). Participants used text messages to record daily bleeding patterns. Our primary outcome was the total number of consecutive amenorrhea days after the first treatment. Secondary outcomes included time to bleeding or spotting cessation and restart after first treatment, overall bleeding patterns, and satisfaction. RESULTS: From January 2017 to November 2018, 112 women enrolled in the study; 88 (79%) completed 90 days, and 79 (71%) completed 180 days. Participant characteristics did not differ between groups; mean age 24, majority identified as white not Hispanic with at least some college education. After the first treatment, the tamoxifen group reported an average of 9.8 (95% CI 4.6-15.0) more consecutive days of amenorrhea and more total days of no bleeding (amenorrhea or spotting) in the first 90 days (median 73.5 [range 24-89] vs 68 [range 11-81], P=.001). The placebo group showed a similar treatment benefit after first active use of tamoxifen in the open-label phase. At the end of the randomized study (first 90 days), women who received tamoxifen reported higher satisfaction (median 62 mm [range 16-100]) than those treated with placebo (46 mm [range 0-100]; P=.023). CONCLUSION: A short course of tamoxifen reduces problematic bleeding and improves satisfaction in users of etonogestrel implants. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02903121.

RESUMO

BACKGROUND: Progesterone is essential for a healthy pregnancy. Several small trials have suggested that progesterone therapy may rescue a pregnancy in women with early pregnancy bleeding, which is a symptom that is strongly associated with miscarriage. OBJECTIVES: (1) To assess the effects of vaginal micronised progesterone in women with vaginal bleeding in the first 12 weeks of pregnancy. (2) To evaluate the cost-effectiveness of progesterone in women with early pregnancy bleeding. DESIGN: A multicentre, double-blind, placebo-controlled, randomised trial of progesterone in women with early pregnancy vaginal bleeding. SETTING: A total of 48 hospitals in the UK. PARTICIPANTS: Women aged 16-39 years with early pregnancy bleeding. INTERVENTIONS: Women aged 16-39 years were randomly assigned to receive twice-daily vaginal suppositories containing either 400 mg of progesterone or a matched placebo from presentation to 16 weeks of gestation. MAIN OUTCOME MEASURES: The primary outcome was live birth at ≥ 34 weeks. In addition, a within-trial cost-effectiveness analysis was conducted from an NHS and NHS/Personal Social Services perspective. RESULTS: A total of 4153 women from 48 hospitals in the UK received either progesterone (n = 2079) or placebo (n = 2074). The follow-up rate for the primary outcome was 97.2% (4038 out of 4153 participants). The live birth rate was 75% (1513 out of 2025 participants) in the progesterone group and 72% (1459 out of 2013 participants) in the placebo group (relative rate 1.03, 95% confidence interval 1.00 to 1.07; p = 0.08). A significant subgroup effect (interaction test p = 0.007) was identified for prespecified subgroups by the number of previous miscarriages: none (74% in the progesterone group vs. 75% in the placebo group; relative rate 0.99, 95% confidence interval 0.95 to 1.04; p = 0.72); one or two (76% in the progesterone group vs. 72% in the placebo group; relative rate 1.05, 95% confidence interval 1.00 to 1.12; p = 0.07); and three or more (72% in the progesterone group vs. 57% in the placebo group; relative rate 1.28, 95% confidence interval 1.08 to 1.51; p = 0.004). A significant post hoc subgroup effect (interaction test p = 0.01) was identified in the subgroup of participants with early pregnancy bleeding and any number of previous miscarriage(s) (75% in the progesterone group vs. 70% in the placebo group; relative rate 1.09, 95% confidence interval 1.03 to 1.15; p = 0.003). There were no significant differences in the rate of adverse events between the groups. The results of the health economics analysis show that progesterone was more costly than placebo (£7655 vs. £7572), with a mean cost difference of £83 (adjusted mean difference £76, 95% confidence interval -£559 to £711) between the two arms. Thus, the incremental cost-effectiveness ratio of progesterone compared with placebo was estimated as £3305 per additional live birth at ≥ 34 weeks of gestation. CONCLUSIONS: Progesterone therapy in the first trimester of pregnancy did not result in a significantly higher rate of live births among women with threatened miscarriage overall, but an important subgroup effect was identified. A conclusion on the cost-effectiveness of the PRISM trial would depend on the amount that society is willing to pay to increase the chances of an additional live birth at ≥ 34 weeks. For future work, we plan to conduct an individual participant data meta-analysis using all existing data sets.

Miscarriage is a common complication of pregnancy that affects one in five pregnancies. Several small studies have suggested that progesterone, a hormone essential for maintaining a pregnancy, may reduce the risk of miscarriage in women presenting with early pregnancy bleeding. This research was undertaken to test whether or not progesterone given to pregnant women with early pregnancy bleeding would increase the number of live births when compared with placebo (dummy treatment). The women participating in the study had an equal chance of receiving progesterone or placebo, as determined by a computer; one group received progesterone (400 mg twice daily as vaginal pessaries) and the other group received placebo with an identical appearance. Treatment began when women presented with vaginal bleeding, were < 12 weeks of gestation and were found to have at least a pregnancy sac on an ultrasound scan. Treatment was stopped at 16 weeks of gestation, or earlier if the pregnancy ended before 16 weeks. Neither the participants nor their health-care professionals knew which treatment was being received. In total, 23,775 women were screened and 4153 women were randomised to receive either progesterone or placebo pessaries. Altogether, 2972 participants had a live birth after at least 34 weeks of gestation. Overall, the live birth rate in the progesterone group was 75% (1513 out of 2025 participants), compared with 72% (1459 out of 2013 participants) in the placebo group. Although the live birth rate was 3% higher in the progesterone group than in the placebo group, there was statistical uncertainty about this finding. However, it was observed that women with a history of one or more previous miscarriages and vaginal bleeding in their current pregnancy may benefit from progesterone. For women with no previous miscarriages, our analysis showed that the live birth rate was 74% (824 out of 1111 participants) in the progesterone group compared with 75% (840 out of 1127 participants) in the placebo group. For women with one or more previous miscarriages, the live birth rate was 75% (689 out of 914 participants) in the progesterone group compared with 70% (619 out of 886 participants) in the placebo group. The potential benefit appeared to be most strong for women with three or more previous miscarriages, who had a live birth rate of 72% (98 out of 137 participants) in the progesterone group compared with 57% (85 out of 148 participants) in the placebo group. Treatment with progesterone did not appear to have any negative effects.
