Abstract
Importance Several medications have been used to achieve medical abortion in the first trimester of pregnancy. The most commonly used is the combination of mifepristone and misoprostol; however, different doses and routes of administration have been proposed. Objective The aim of this study was to summarize published data on the effectiveness, adverse effects, and acceptability of the various combinations of mifepristone and misoprostol in medical abortion protocols in the first trimester of pregnancy. Evidence Acquisition This was a comprehensive review, synthesizing the findings of the literature on the current use of mifepristone and misoprostol for first-trimester abortion. Results The combination of mifepristone and misoprostol seems to be more effective than misoprostol alone. Regarding the dosages and routes, mifepristone is administered orally, and the optimal dose is 200 mg. The route of administration of misoprostol varies; the sublingual and buccal routes are more effective; however, the vaginal route (800 μg) is associated with fewer adverse effects. Finally, the acceptability rates did not differ significantly. Conclusions Different schemes for first-trimester medical abortion have been described so far. Future research needs to focus on identifying the method that offers the best trade-off between efficacy and safety in first-trimester medical abortion.

Abstract
Denial of pregnancy is a rare psychic process associated with an increased risk of infant death. Forensic examinations to determine viability at birth can heavily influence the legal proceedings in cases of clandestine deliveries that result in the death of the infant. A 32-year-old woman who experienced a denial of pregnancy up to 30 weeks of amenorrhea reported giving birth at home at an estimated term of 35 weeks of amenorrhea. No one witnessed the delivery. She claimed the infant was stillborn. Forensic examinations revealed characteristic features of a live born infant. The mother tested positive for mifepristone. Mifepristone is an anti-progestin drug used for early abortion and to induce labor in cases of in-utero fetal death in later pregnancy. Even if mifepristone crosses the placenta, it has no direct toxic effect on the fetus. Our observations suggest premature live birth caused by mifepristone, followed by asphyxia due to meconium inhalation syndrome associated with lung immaturity especially since the birth occurred at home and no medical care was provided after the birth. The tragic outcome of this clinical case calls for vigilance and global management, including the psychiatric care of parturients in the context of late discovery of pregnancy. In France, this situation showed a legal gap between the consideration of the fetus and laws concerning abortion. To our knowledge, in France, this case has allowed the court to set a legal precedent as a similar case had never been reported elsewhere.

Abstract
Background Estrogen has been usually used in clinic for medical pretreatment of early pregnancy loss. There was little reported the effect of estrogen combined with prostaglandin analogs in the medical management of early pregnancy loss. This retrospective study aimed to evaluate the efficacy of estrogen pretreatment for medical management of early pregnancy loss and explore the confounding factor of intrauterine adhesion (IUA) on the outcome of medical management. Methods A total of 226 early pregnancy loss patients who received pretreatment with estradiol valerate and/or mifepristone, followed by carboprost methylate suppositories (study groups), or carboprost methylate suppositories alone (control group) in a regional central institution from March 2020 to February 2021 were retrospectively studied. All patients were evaluated by hysteroscopy 6 h after carboprost methylate suppositories use to assess whether the gestational sac was complete expulsion and assess the morphology of uterine cavity. Results The complete expulsion rate was 56.94% in the mifepristone and estradiol valerate-pretreatment group, 20.69% in the estradiol valerate-pretreatment group, 62.5% in the mifepristone-pretreatment group, and 12.5% in the control group. Compared with the control group, pretreatment with estradiol valerate did not increase the complete expulsion rate significantly (P = 0.297), pretreatment with mifepristone increased the complete expulsion rate significantly (P < 0.001). Pretreatment with mifepristone combined with estradiol valerate did not increase the complete expulsion rate significantly comparing with pretreatment with mifepristone (P = 0.222). The data of IUA showed that the complete expulsion rate in patients with IUA was lower than that in those patients without IUA (P < 0.001). Conclusions Pretreatment with estrogen was not a sensible substitute for mifepristone in the medical management of early pregnancy loss. Mifepristone followed by carboprost methylate suppositories was likelihood of the ideal medical scheme in early pregnancy loss. IUA decreased the complete expulsion rate of medical management, it is cautious about medical management for early pregnancy loss with risk of IUA. Trial Registration Number: ChiCTR2100046503.

Abstract
This study aimed to evaluate clinical predictors associated with complete miscarriage after medical treatment for early pregnancy loss (EPL) in women with previous cesarean section. Patients with retained uterine content after expulsion followed by administration of mifepristone and misoprostol were included if they chose continued medical treatment rather than surgical intervention. Clinical characteristics including maternal age, gravidity, parity, history of previous cesarean section and ultrasound findings regarding average diameter of the gestational sac, uterine position, width, and blood flow signal of the residual uterine content after expulsion of the gestational sac were included in the analysis to determine predictors of complete miscarriage. A recursive partitioning analysis (RPA) was used to divide the patients into probability groups and assess their probability of complete miscarriage. A total of 89 patients were analyzed. The complete miscarriage rate was 58.43% overall. Multivariable logistic regression analysis showed that the width and blood flow signal of the residual after expulsion were both independent predictors for complete miscarriage (all P < .05). Patients were divided into high-probability (no blood flow signal, width of residual <1 cm), intermediate-probability (no blood flow signal, width of residual ≥1 cm; blood flow signal, width of residual <1 cm), and low-probability (blood flow signal, width of residual ≥ 1 cm) groups by RPA according to these 2 factors. The incidences of complete miscarriage were 88.24%, 67.57%, and 34.29%, respectively, P < .001). Surgical evacuation may be avoided in patients without ultrasonic blood flow of the uterine residual and width of the residual <1 cm. More active treatment could be recommended for patients with ultrasonic blood flow of the uterine residual and width of the residual ≥ 1 cm. Clinicians and patients should be aware of these differences when proceeding with medical treatment for EPL patients with previous cesarean section.

Abstract
BACKGROUND Medical abortion became an alternative method of pregnancy termination following the development of prostaglandins and antiprogesterone in the 1970s and 1980s. Recently, synthesis inhibitors of oestrogen (such as letrozole) have also been used to enhance efficacy. The most widely researched drugs are prostaglandins (such as misoprostol, which has a strong uterotonic effect), mifepristone, mifepristone with prostaglandins, and letrozole with prostaglandins. More evidence is needed to identify the best dosage, regimen, and route of administration to optimise patient outcomes. This is an update of a review last published in 2011. OBJECTIVES To compare the effectiveness and side effects of different medical methods for first trimester abortion. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Global Health, and LILACs on 28 February 2021. We also searched Clinicaltrials.gov and the World Health Organization's (WHO) International Clinical Trials Registry Platform, and reference lists of retrieved papers. SELECTION CRITERIA We considered randomised controlled trials (RCTs) that compared different medical methods for abortion before the 12th week of gestation. The primary outcome is failure to achieve complete abortion. Secondary outcomes are mortality, surgical evacuation, ongoing pregnancy at follow-up, time until passing of conceptus, blood transfusion, side effects and women's dissatisfaction with the method. DATA COLLECTION AND ANALYSIS Two review authors independently selected and evaluated studies for inclusion, and assessed the risk of bias. We processed data using Review Manager 5 software. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included 99 studies in the review (58 from the original review and 41 new studies). 1. Combined regimen mifepristone/prostaglandin Mifepristone dose: high-dose (600 mg) compared to low-dose (200 mg) mifepristone probably has similar effectiveness in achieving complete abortion (RR 1.07, 95% CI 0.87 to 1.33; I2 = 0%; 4 RCTs, 3494 women; moderate-certainty evidence). Prostaglandin dose: 800 µg misoprostol probably reduces abortion failure compared to 400 µg (RR 0.63, 95% CI 0.51 to 0.78; I2= 0%; 3 RCTs, 4424 women; moderate-certainty evidence). Prostaglandin timing: misoprostol administered on day one probably achieves more success on complete abortion than on day three (RR 1.94, 95% CI 1.05 to 3.58; 1489 women; 1 RCT; moderate-certainty evidence). Administration strategy: there may be no difference in failure of complete abortion with self-administration at home compared with hospital administration (RR 1.63, 95% CI 0.68 to 3.94; I2 = 84%; 2263 women; 4 RCTs; low-certainty evidence), but failure may be higher when administered by nurses in hospital compared to by doctors in hospital (RR 2.69, 95% CI 1.39 to 5.22; I2 = 66%; 3 RCTs, 3056 women; low-certainty evidence). Administration route: oral misoprostol probably leads to more failures than the vaginal route (RR 2.38, 95% CI 1.46 to 3.87; I2 = 39%; 3 RCTs, 1704 women; moderate-certainty evidence) and may be associated with more frequent side effects such as nausea (RR 1.14, 95% CI 1.03 to 1.26; I2 = 0%; 2 RCTs, 1380 women; low-certainty evidence) and diarrhoea (RR 1.80 95% CI 1.49 to 2.17; I2 = 0%; 2 RCTs, 1379 women). Compared with the vaginal route, complete abortion failure is probably lower with sublingual (RR 0.68, 95% CI 0.22 to 2.11; I2 = 59%; 2 RCTs, 3229 women; moderate-certainty evidence) and may be lower with buccal administration (RR 0.71, 95% CI 0.34 to 1.46; I2 = 0%; 2 RCTs, 479 women; low-certainty evidence), but sublingual or buccal routes may lead to more side effects. Women may experience more vomiting with sublingual compared to buccal administration (RR 1.33, 95% CI 1.01 to 1.77; low-certainty evidence). 2. Mifepristone alone versus combined regimen The efficacy of mifepristone alone in achieving complete abortion compared to combined mifepristone/prostaglandin up to 12 weeks is unclear (RR of failure 3.25, 95% CI 0.81 to 13.09; I2 = 83%; 3 RCTs, 273 women; very low-certainty evidence). 3. Prostaglandin alone versus combined regimen Nineteen studies compared prostaglandin alone to a combined regimen (prostaglandin combined with mifepristone, letrozole, estradiol valerate, tamoxifen, or methotrexate). Compared to any of the combination regimens, misoprostol alone may increase the risk for failure to achieve complete abortion (RR of failure 2.39, 95% CI 1.89 to 3.02; I2 = 64%; 18 RCTs, 3471 women; low-certainty evidence), and with more diarrhoea. 4. Prostaglandin alone (route of administration) Oral misoprostol alone may lead to more failures in complete abortion than the vaginal route (RR 3.68, 95% CI 1.56 to 8.71, 2 RCTs, 216 women; low-certainty evidence). Failure to achieve complete abortion may be slightly reduced with sublingual compared with vaginal (RR 0.69, 95% CI 0.37 to 1.28; I2 = 87%; 5 RCTs, 2705 women; low-certainty evidence) and oral administration (RR 0.58, 95% CI 0.11 to 2.99; I2 = 66%; 2 RCTs, 173 women). Failure to achieve complete abortion may be similar or slightly higher with sublingual administration compared to buccal administration (RR 1.11, 95% CI 0.71 to 1.74; 1 study, 401 women). AUTHORS' CONCLUSIONS Safe and effective medical abortion methods are available. Combined regimens (prostaglandin combined with mifepristone, letrozole, estradiol valerate, tamoxifen, or methotrexate) may be more effective than single agents (prostaglandin alone or mifepristone alone). In the combined regimen, the dose of mifepristone can probably be lowered to 200 mg without significantly decreasing effectiveness. Vaginal misoprostol is probably more effective than oral administration, and may have fewer side effects than sublingual or buccal. Some results are limited by the small numbers of participants on which they are based. Almost all studies were conducted in settings with good access to emergency services, which may limit the generalisability of these results.

Economic evaluation of a randomized controlled trial comparing mifepristone and misoprostol with misoprostol alone in the treatment of early pregnancy loss. PLoS One 2022; 17:e0262894. [PMID: 35139105 PMCID: PMC8827447 DOI: 10.1371/journal.pone.0262894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 01/05/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND In case of early pregnancy loss (EPL) women can either choose for expectant, medical or surgical management. One week of expectant management is known to lead to spontaneous abortion in approximately 50% of women. Medical treatment with misoprostol is known to be safe and less costly than surgical management, however less effective in reaching complete evacuation of the uterus. Recently, a number of trials showed that prompt treatment with the sequential combination of mifepristone with misoprostol is superior to misoprostol alone in reaching complete evacuation. In this analysis we evaluate whether the sequential combination of mifepristone with misoprostol is cost-effective compared to misoprostol alone, in the treatment of EPL. METHODS AND FINDINGS A cost-effectiveness analysis (CEA) from a healthcare perspective was performed alongside a randomised controlled trial (RCT) in which standard treatment with misoprostol only was compared with a combination of mifepristone and misoprostol, in women with EPL after a minimum of one week of unsuccessful management. A limited societal perspective scenario was added. This RCT, the Triple M trial, was a multicentre, randomized, double-blinded, placebo-controlled trial executed at 17 hospitals in the Netherlands. The trial started on June 27th 2018, and ended prematurely in January 2020 due to highly significant outcomes from the predefined interim-analysis. We included 351 women with a diagnosis of EPL between 6 and 14 weeks gestation after at least one week of unsuccessful expectant management. They were randomized between double blinded pre-treatment with oral mifepristone 600mg (N = 175) or placebo (N = 176) taken on day one, both followed by misoprostol orally. In both groups, an intention-to-treat analysis was performed for 172 patients, showing a significant difference in success rates between participants treated with mifepristone and misoprostol versus those treated with misoprostol alone (79.1% vs 58.7% respectively). In this cost-effective analysis we measured the direct, medical costs related to treatment (planned and unplanned hospital visits, medication, additional treatment) and indirect costs based on the IMTA Productivity Cost Questionnaire (iPCQ). Quality Adjusted Life Years (QALY's) were calculated from participants' scores on the SF-36 questionnaires sent digitally at treatment start, and one, two and six weeks later. We found medical treatment with placebo followed by misoprostol to be 26% more expensive compared to mifepristone followed by misoprostol (p = 0.001). Mean average medical costs per patient were significantly lower in the mifepristone group compared to the placebo group (€528.95 ± 328.93 vs €663.77 ± 456.03, respectively; absolute difference €134.82, 95% CI 50,46-219,18, p = 0.002). Both indirect costs and QALY's were similar between both groups. CONCLUSION The sequential combination of mifepristone with misoprostol is cost-effective compared with misoprostol alone, for treatment of EPL after a minimum of one week of unsuccessful expectant management.

Abstract
OBJECTIVE To compare the effectiveness and safety of repeat misoprostol versus expectant management in women with first-trimester incomplete miscarriage who have been initially treated with misoprostol. METHODS The study was an open-labeled randomized controlled trial including women with an incomplete first-trimester miscarriage after administration of misoprostol. The participants were randomly assigned to vaginal misoprostol or expectant management using a computer-generated table of random numbers. The primary outcome was the number of women with a complete miscarriage at 1 week. RESULTS Eighty-eight women (44 women in each group) were analyzed. The rate of complete miscarriage at 1 week was significantly higher in the misoprostol group than the expectant management group-29 (69.0%) versus 7 (16.7%) (P < 0.001), respectively. Women in the misoprostol group were more satisfied (7.00 ± 0.77 vs 4.57 ± 1.61, P < 0.001) but reported more pain (7.95 ± 1.85 vs 5.26 ± 1.08, P < 0.001) than women in the expectant group. The misoprostol group reported more adverse effects than the expectant management group (P < 0.001). CONCLUSION In women with an incomplete first-trimester miscarriage who were initially treated with misoprostol, repeat administration of misoprostol was more effective than expectant management for achieving complete miscarriage at 1 week. However, misoprostol was associated with more adverse effects. REGISTRATION SITE AND NUMBER Clinicaltrials.gov: NCT03148561.

Abstract
BACKGROUND Miscarriage, defined as the spontaneous loss of a pregnancy before 24 weeks' gestation, is common with approximately 25% of women experiencing a miscarriage in their lifetime. An estimated 15% of pregnancies end in miscarriage. Miscarriage can lead to serious morbidity, including haemorrhage, infection, and even death, particularly in settings without adequate healthcare provision. Early miscarriages occur during the first 14 weeks of pregnancy, and can be managed expectantly, medically or surgically. However, there is uncertainty about the relative effectiveness and risks of each option. OBJECTIVES To estimate the relative effectiveness and safety profiles for the different management methods for early miscarriage, and to provide rankings of the available methods according to their effectiveness, safety, and side-effect profile using a network meta-analysis. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth's Trials Register (9 February 2021), ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (12 February 2021), and reference lists of retrieved studies. SELECTION CRITERIA We included all randomised controlled trials assessing the effectiveness or safety of methods for miscarriage management. Early miscarriage was defined as less than or equal to 14 weeks of gestation, and included missed and incomplete miscarriage. Management of late miscarriages after 14 weeks of gestation (often referred to as intrauterine fetal deaths) was not eligible for inclusion in the review. Cluster- and quasi-randomised trials were eligible for inclusion. Randomised trials published only as abstracts were eligible if sufficient information could be retrieved. We excluded non-randomised trials. DATA COLLECTION AND ANALYSIS At least three review authors independently assessed the trials for inclusion and risk of bias, extracted data and checked them for accuracy. We estimated the relative effects and rankings for the primary outcomes of complete miscarriage and composite outcome of death or serious complications. The certainty of evidence was assessed using GRADE. Relative effects for the primary outcomes are reported subgrouped by the type of miscarriage (incomplete and missed miscarriage). We also performed pairwise meta-analyses and network meta-analysis to determine the relative effects and rankings of all available methods. MAIN RESULTS Our network meta-analysis included 78 randomised trials involving 17,795 women from 37 countries. Most trials (71/78) were conducted in hospital settings and included women with missed or incomplete miscarriage. Across 158 trial arms, the following methods were used: 51 trial arms (33%) used misoprostol; 50 (32%) used suction aspiration; 26 (16%) used expectant management or placebo; 17 (11%) used dilatation and curettage; 11 (6%) used mifepristone plus misoprostol; and three (2%) used suction aspiration plus cervical preparation. Of these 78 studies, 71 (90%) contributed data in a usable form for meta-analysis. Complete miscarriage Based on the relative effects from the network meta-analysis of 59 trials (12,591 women), we found that five methods may be more effective than expectant management or placebo for achieving a complete miscarriage: · suction aspiration after cervical preparation (risk ratio (RR) 2.12, 95% confidence interval (CI) 1.41 to 3.20, low-certainty evidence), · dilatation and curettage (RR 1.49, 95% CI 1.26 to 1.75, low-certainty evidence), · suction aspiration (RR 1.44, 95% CI 1.29 to 1.62, low-certainty evidence), · mifepristone plus misoprostol (RR 1.42, 95% CI 1.22 to 1.66, moderate-certainty evidence), · misoprostol (RR 1.30, 95% CI 1.16 to 1.46, low-certainty evidence). The highest ranked surgical method was suction aspiration after cervical preparation. The highest ranked non-surgical treatment was mifepristone plus misoprostol. All surgical methods were ranked higher than medical methods, which in turn ranked above expectant management or placebo. Composite outcome of death and serious complications Based on the relative effects from the network meta-analysis of 35 trials (8161 women), we found that four methods with available data were compatible with a wide range of treatment effects compared with expectant management or placebo: · dilatation and curettage (RR 0.43, 95% CI 0.17 to 1.06, low-certainty evidence), · suction aspiration (RR 0.55, 95% CI 0.23 to 1.32, low-certainty evidence), · misoprostol (RR 0.50, 95% CI 0.22 to 1.15, low-certainty evidence), · mifepristone plus misoprostol (RR 0.76, 95% CI 0.31 to 1.84, low-certainty evidence). Importantly, no deaths were reported in these studies, thus this composite outcome was entirely composed of serious complications, including blood transfusions, uterine perforations, hysterectomies, and intensive care unit admissions. Expectant management and placebo ranked the lowest when compared with alternative treatment interventions. Subgroup analyses by type of miscarriage (missed or incomplete) agreed with the overall analysis in that surgical methods were the most effective treatment, followed by medical methods and then expectant management or placebo, but there are possible subgroup differences in the effectiveness of the available methods. AUTHORS' CONCLUSIONS: Based on relative effects from the network meta-analysis, all surgical and medical methods for managing a miscarriage may be more effective than expectant management or placebo. Surgical methods were ranked highest for managing a miscarriage, followed by medical methods, which in turn ranked above expectant management or placebo. Expectant management or placebo had the highest chance of serious complications, including the need for unplanned or emergency surgery. A subgroup analysis showed that surgical and medical methods may be more beneficial in women with missed miscarriage compared to women with incomplete miscarriage. Since type of miscarriage (missed and incomplete) appears to be a source of inconsistency and heterogeneity within these data, we acknowledge that the main network meta-analysis may be unreliable. However, we plan to explore this further in future updates and consider the primary analysis as separate networks for missed and incomplete miscarriage.

Abstract
RESEARCH QUESTION What is the global variability in misoprostol treatment for the management of early pregnancy loss (EPL)? DESIGN An international web-based survey of fertility specialists and obstetrics and gynaecology clinicians was conducted between August and November 2020. The survey consisted of 16 questions addressing several aspects of misoprostol treatment for EPL. RESULTS Overall, 309 clinicians from 80 countries participated in the survey, of whom 67.3% were fertility specialists. Nearly one-half (47.9%) of the respondents let the patient choose the first line of treatment (expectant management, misoprostol treatment or surgical aspiration) according to her own preference. The 248 respondents who administer misoprostol in their daily practice were asked further questions; 59.7% of them advise patients to take the medication at home. The most common dose and route of administration is 800 µg administered vaginally. Only 28.6% of participants use mifepristone pretreatment. Variation in the timing of the first follow-up visit after misoprostol administration was wide, ranging from 24 h to 1 week in most clinics. In case of incomplete expulsion, only 42.3% of the respondents routinely administer a second dose. The timing of the final visit and the definition of successful treatment also differed greatly among respondents. CONCLUSIONS There is large variability in the use of misoprostol for the management of EPL. High-quality research is necessary to examine several aspects of the treatment. Particularly, the timing and effectiveness of a second dose administration and the criteria to decide on treatment failure or success deserve more research in the future.

Abstract
BACKGROUND Worldwide, millions of women seek treatment for early pregnancy loss (EPL) annually. Medical management with misoprostol is widely used, but only effective 60% of the time. Pre-treatment with mifepristone prior to misoprostol might improve the success rate of medical management. METHODS This was a multi-centre, double-blind, placebo-controlled randomised trial in 17 Dutch hospitals. Women with a non-viable pregnancy between 6 and 14 weeks of gestation were eligible for inclusion after at least one week of expectant management. Participants were randomised (1:1) between oral mifepristone 600 mg or an oral placebo tablet. Participants took 400 μg misoprostol orally, repeated after four hours on day two and, if necessary, day three. Primary outcome was expulsion of gestational sac and endometrial thickness <15 mm after 6-8 weeks. Analyses were done according to intention-to-treat principles. This trial is registered with ClinicalTrials.gov, NCT03212352. FINDINGS Between June 28th 2018 and January 8th 2020, 175 women were randomised to mifepristone and 176 to placebo, including 344 in the intention-to-treat analysis. In the mifepristone group 136 (79•1%) of 172 participants reached complete evacuation compared to 101 (58•7%) of 172 participants in the placebo group (p<0•0001, RR 1•35, 95% CI 1•16-1•56). Incidence of serious adverse events was significantly lower in the mifepristone group with 24 (14%) patients affected versus 55 (32%) in the placebo group (p = 0•0005) (Table 3). INTERPRETATION Pre-treatment with mifepristone prior to misoprostol was more effective than misoprostol alone in managing EPL.
