Abstract
OBJECTIVES Previous research has demonstrated the effectiveness of misoprostol for treatment of incomplete abortion; however, few studies have systematically compared misoprostol's effectiveness with that of standard surgical care. This study documents the effectiveness of a single 600 micrograms dose of oral misoprostol versus manual vacuum aspiration (MVA) for treatment of incomplete abortion in a developing country setting. DESIGN Open-label randomised controlled trial. SETTING Two university teaching hospitals in Burkina Faso, West Africa. POPULATION Women of reproductive age presenting with incomplete abortion. METHODS From April 2004 through October 2004, 447 consenting women with incomplete abortion were randomised to either a single dose of 600 micrograms oral misoprostol or MVA for treatment of their condition. MAIN OUTCOME MEASURE Completed abortion following initial treatment. RESULTS Regardless of treatment assigned, nearly all participants had a complete uterine evacuation (misoprostol = 94.5%, MVA = 99.1%; relative risk [RR] = 0.95 [95% CI 0.92-0.99]). Acceptability and satisfaction ratings were similar and high for both misoprostol and MVA, with three out of four women indicating that the treatment's adverse effects were tolerable (misoprostol = 72.9%, MVA = 75.8%; RR = 0.96 [95% CI 0.86-1.07]). The majority of women were 'satisfied' or 'very satisfied' with the method they received (misoprostol = 96.8%, MVA = 97.7%; RR = 0.99 [95% CI 0.96-1.02]), expressed a desire to choose that method again (misoprostol = 94.5%, MVA = 86.6%; RR = 1.09 [95% CI 1.03-1.16]) and to recommend it to a friend (misoprostol = 94.5%, MVA = 85.2%; RR = 1.11 [95% CI 1.04-1.18]). CONCLUSION Six hundred micrograms of oral misoprostol is as safe and acceptable as MVA for the treatment of incomplete abortion. Operations research is needed to ascertain the role of misoprostol within postabortion care programmes worldwide.

Abstract
BACKGROUND The long-term safety of surgical abortion in the first trimester is well established. Despite the increasing use of medical abortion (abortion by means of medication), limited information is available regarding the effects of this procedure on subsequent pregnancies. METHODS We identified all women living in Denmark who had undergone an abortion for nonmedical reasons between 1999 and 2004 and obtained information regarding subsequent pregnancies from national registries. Risks of ectopic pregnancy, spontaneous abortion, preterm birth (at <37 weeks of gestation), and low birth weight (<2500 g) in the first subsequent pregnancy in women who had had a first-trimester medical abortion were compared with risks in women who had had a first-trimester surgical abortion. RESULTS Among 11,814 pregnancies in women who had had a previous first-trimester medical abortion (2710 women) or surgical abortion (9104 women), there were 274 ectopic pregnancies (respective incidence rates, 2.4% and 2.3%), 1426 spontaneous abortions (12.2% and 12.7%), 552 preterm births (5.4% and 6.7%), and 478 births with low birth weight (4.0% and 5.1%). After adjustment for maternal age, interval between pregnancies, gestational age at abortion, parity, cohabitation status, and urban or nonurban residence, medical abortion was not associated with a significantly increased risk of ectopic pregnancy (relative risk, 1.04; 95% confidence interval [CI], 0.76 to 1.41), spontaneous abortion (relative risk, 0.87; 95% CI, 0.72 to 1.05), preterm birth (relative risk, 0.88; 95% CI, 0.66 to 1.18), or low birth weight (relative risk, 0.82; 95% CI, 0.61 to 1.11). Gestational age at medical abortion was not significantly associated with any of these adverse outcomes. CONCLUSIONS We found no evidence that a previous medical abortion, as compared with a previous surgical abortion, increases the risk of spontaneous abortion, ectopic pregnancy, preterm birth, or low birth weight.

Vaginal vs. sublingual misoprostol with mifepristone for cervical priming in second-trimester abortion by dilation and evacuation: a randomized clinical trial. Contraception 2007; 75:230-7. [PMID: 17303495 DOI: 10.1016/j.contraception.2006.11.007] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2006] [Revised: 11/09/2006] [Accepted: 11/09/2006] [Indexed: 10/23/2022]
Abstract
OBJECTIVES The study was conducted to assess the effectiveness of mifepristone 200 mg 48 h before administering misoprostol 600 mug, sublingual vs. vaginal route, prior to dilation and evacuation (D&E) in 12- to 20-week pregnancies. DESIGN Randomized clinical trial. SETTING Clínica Mediterrania Médica, Valencia, Spain. SUBJECTS Women with 12- to 20-week pregnancies wanting a voluntary abortion between July 9, 2004, and February 9, 2006. METHODS Nine hundred women were randomized to be included in one of the following four groups: (I) mifepristone 200 mg plus sublingual misoprostol 600 microg before D&E, (II) mifepristone 200 mg plus vaginal misoprostol 600 microg before D&E, (III) sublingual misoprostol 600 microg before D&E and (IV) vaginal misoprostol 600 microg before D&E. MAIN OUTCOMES MEASURED The degree of cervical dilation achieved before D&E, surgical time necessary to terminate the pregnancy and side effects of misoprostol. RESULTS The average cervical dilation in the mifepristone groups was 12.5+/-2.8 mm (SD) [95% confidence interval (CI), 12.3-12.8] vs. 8.5+/-3.2 mm (SD) (95% CI, 8.2-8.8) in those receiving only misoprostol. Surgical time in the mifepristone sublingual misoprostol group was 11.9+/-4.3 min (SD) vs. 13.0+/-5.3 min (SD) in the sublingual misoprostol group without mifepristone (p=.007); in the mifepristone vaginal misoprostol group, the average surgical time was 12.3+/-5.0 min (SD) vs. 13.0+/-6.2 (SD) in the vaginal misoprostol group without mifepristone (p=.031). CONCLUSIONS Administering mifepristone before D&E with misoprostol in second-trimester abortions makes surgery easier and shorter and, to a certain extent, lessens the risk of cervical injuries, especially in D&E in advanced gestational periods.

Abstract
This article provides an overview of medication abortion in the United States 6 years after the approval of mifepristone (RU486; Mifeprex; Danco Laboratories, LLC, New York, NY) by the US Food and Drug Administration (FDA). The adoption of mifepristone is considered in the context of epidemiologic data on abortion, abortion access, and the safety of abortion. The risks of medication and aspiration abortion are discussed in the context of abortion-related mortality, recent experience with obstetric and gynecologic infection with Clostridium sordellii, and the limits of scientific knowledge on the incidence of this infection in women. Innovative protocols studied since FDA approval of mifepristone are presented, and implications for clinical practice are discussed.

Abstract
BACKGROUND In an attempt to improve efficacy for women who desire medical management of early pregnancy failure (EPF), we studied the efficacy and acceptability of mifepristone 200 mg, orally (po), followed 24 h later by misoprostol 800 microg, vaginally (pv), for the treatment of EPF. METHODS We enrolled 30 women with EPF in this pilot clinical trial. All women used misoprostol 800 microg, pv, 24 h after ingesting 200 mg mifepristone. Follow-up evaluations with transvaginal ultrasonography occurred at 24 h and 1 week after treatment. Participants were offered a repeat dose of misoprostol if the pregnancy had not been expelled at the first follow-up. RESULTS The expulsion rate with one dose of misoprostol was 90% (95% CI=79-100%). The overall success rate of the treatment was 93% (95% CI=84-100%). CONCLUSION This regimen of mifepristone followed by vaginal misoprostol appears to be an efficacious and acceptable treatment for EPF and may have improved results over a single dose of misoprostol alone.

Abstract
Rupture of unscarred uterus during the second trimester is rare. A case of ruptured uterus in a multiparous woman is presented. To our knowledge, this might be the first reported case in the English literature of uterine rupture during second trimester termination of pregnancy using ethacridine lactate. This case is also rare as uterine rupture is presented with an insidious course rather than acute, thus delaying the diagnosis.

Abstract
Exhibiting a strong affinity to the progesterone and the glucocorticoid receptors, mifepristone exert competitive antagonism to these hormones both in in vitro and in animal experiments. Due to its antiprogesterone activity, it was proposed that mifepristone be used for the termination of early human pregnancy. Mifepristone, at a dose of 600 mg initially used alone, was then used with a subsequent low dose of prostaglandin that led to a success rate of 95% as a medical method for early termination of pregnancy (TOP), and the occurrence of continuing pregnancy was reduced to <or=1%. Its use was extended to other indications, such as cervical dilatation prior to surgical TOP in the first trimester, therapeutic TOP for medical reasons beyond the first trimester and for labor induction in case of fetal death in utero. The efficacy and safety of this treatment have been confirmed based on its use for over 15 years since its first approval in France and with close adherence to the approved recommendations. This article describes the toxicology studies conducted in animals as well as the safety follow-up and side effects reported with use of the compound when used with misoprostol in the main indication that is currently approved in 31 countries. Special emphasis is given to the rare but relevant safety issues, that is, heavy uterine bleeding, pelvic infections and continuing pregnancies. The rationale for warnings and contraindications for use of the product are also explained.

Abstract
OBJECTIVE To analyze and evaluate the acceptability of mifepristone compatible with misoprostone versus conventional surgical abortion among women under unwanted early pregnancy, so as to help the unexpected pregnant women to choose the satisfactory abortion, and to provide the evidence for clinicians to make a proper clinical decision. METHODS Six medical databases were searched, including MEDLINE, EMBASE, Cochrane library, CBMdisc, CNKI and VIP, together with twelve journals hand-searched, and references of included studies additionally searched. Two qualified reviewers reviewed the original articles, evaluating qualities of articles, and extracting data independently. After heterogeneity test, the data was pooled using Revman software if capable, or descriptive analysis was applied. RESULTS In total, nine original clinical controlled trials were included, containing 3565 cases. Before abortion, more unwanted pregnant women chose the medical abortion because they believed medical abortion was less painful than surgical abortion (OR = 466.51, 95% CI: 91.37 - 2381.88), but medical abortion was less time-consuming than surgical abortion (OR = 0.02, 95% CI: 0.01 - 0.06). After abortion, satisfaction with medical abortion was similar to that with surgical abortion, with insignificant difference (P = 0.89). However, second choice and recommendation rates of medical abortion were much higher than those of surgical abortion with OR and 95% CI as 2.72, 2.13 - 3.47 and 4.19, 2.16 - 11.16, respectively. CONCLUSIONS Medical abortion was less painful than surgical abortion and the rate of second choice and recommendation to others were all also higher than those of surgical abortion. However, the process of medical abortion was not as quick as surgical abortion but the satifacation of both methods seemed similar. Therefore, the two artificial abortion methods were not recommended to replace each other at the present time.

Abstract
Endometritis and toxic shock syndrome associated with Clostridium sordellii have previously been reported after childbirth and, in one case, after medical abortion. We describe four deaths due to endometritis and toxic shock syndrome associated with C. sordellii that occurred within one week after medically induced abortions. Clinical findings included tachycardia, hypotension, edema, hemoconcentration, profound leukocytosis, and absence of fever. These cases indicate the need for physician awareness of this syndrome and for further study of its association with medical abortion.

Abstract
OBJECTIVE:To explain the role of mifepristone in medical abortions that results in fulminant and lethal septic shock due to Clostridium sordellii.DATA SOURCES:MEDLINE, PubMed, and Google Scholar databases were searched (1984–March 2005%). Key search terms were mifepristone, RU38486, RU486, Mifeprex, medical abortion, septic shock, innate immune system, cytokines, and Clostridium sordellii.STUDY SELECTION AND DATA EXTRACTION:All articles identified from the data sources were evaluated and all information deemed relevant was included for the information related to the development of the understanding of the pathophysiology of mifepristone-induced septic shock due to C. sordellii.DATA SYNTHESIS:The mechanisms of action of mifepristone were incorporated into the pathophysiology of septic shock due to C. sordellii. Mifepristone, by blocking both progesterone and glucocorticoid receptors, interferes with the controlled release and functioning of cortisol and cytokines. Failure of physiologically controlled cortisol and cytokine responses results in an impaired innate immune system that results in disintegration of the body's defense system necessary to prevent the endometrial spread of C. sordellii infection. The abnormal cortisol and cytokine responses due to mifepristone coupled to the release of potent exotoxins and an endotoxin from C. sordellii are the major contributors to the rapid development of lethal septic shock.CONCLUSIONS:Theoretically, it appears that the mechanisms of mifepristone action favor the development of infection that leads to septic shock and intensifies the actions of multiple inflammatory cytokines, resulting in fulminant, lethal septic shock.

Abstract
On July 19, 2005, the Food and Drug Administration (FDA) issued a public health advisory regarding the deaths of four women in the United States after medical abortions with Mifeprex (mifepristone, formerly RU-486; Danco Laboratories, New York, New York) and intravaginal misoprostol. Two of these deaths occurred in 2003, one in 2004, and one in 2005. Two of these U.S. cases had clinical illness consistent with toxic shock and had evidence of endometrial infection with Clostridium sordellii, a gram-positive, toxin-forming anaerobic bacteria. In addition, a fatal case of C. sordellii toxic shock syndrome after medical abortion with mifepristone and misoprostol was reported in 2001, in Canada. All three cases of C. sordellii infection were notable for lack of fever, and all had refractory hypotension, multiple effusions, hemoconcentration, and a profound leukocytosis. C. sordellii previously has been described as a cause of pregnancy-associated toxic shock syndrome.

Abstract
OBJECTIVES This study compares the gynaecological symptoms of women who have undergone an induced abortion to those who have not. We also compare the gynaecological side effects, in particular the infectious symptoms, following an induced abortion, according to the abortion technique, medical and surgical, in the year after the abortion. PATIENTS AND METHODS A representative sample of 2863 women, aged 18 to 44, was interviewed by telephone between September 2000 and January 2001. Of these women, 401 declared an abortion in the last 5 years. Analysis of the gynaecological side effects according to the abortion technique was performed among the 199 women who terminated their pregnancy before the 8th week of amenorrhoea. RESULTS Women with a history of induced abortion had a higher sexual risk profile than those with no such history. They also more frequently reported genital infectious symptoms. The comparison between medical and surgical abortions shows that women who had a medical abortion were more likely to report heavy and prolonged bleeding. On the contrary, we found no difference of infectious symptoms between the two techniques. DISCUSSION AND CONCLUSION Our study does not support the idea of a reduction of infectious complications related to medical as opposed to surgical abortions. However, given the rapid diffusion of medical abortion, it seems important to carry on the investigations on the side effects related to medical abortions, in order to prevent them if necessary.

Abstract
Surgical abortion using vacuum aspiration or dilatation and curettage has been the method of choice for termination of pregnancy up to 63 days' gestation since the 1960s. Over the last three decades many studies have explored the use of medical methods for inducing abortion at these gestations. Earlier regimens assessed the systemic and intrauterine injection of prostaglandins. This was followed in the 1980s by the introduction of the antiprogesterone, mifepristone. Since its introduction, the uptake of medical abortion has been steadily increasing in countries where it has been available for routine use. Most current clinical protocols require the use of prostaglandins in combination with anti-progesterones or antimetabolites. The safety, efficacy and acceptability of the medical regimen are now well established at all gestations of pregnancy. Provision of medical abortion increases the choice available to women, in particular those wishing to avoid surgery.

Abstract
OBJECTIVE To evaluate and compare medical abortion versus surgical abortion in respect of their influence on the safety of the mother and baby in the subsequent pregnancy and parturition. METHODS Based on the principle of informed consent of subjects, 150 healthy pregnant women with a past history of having experienced medical abortion once were included in the study group (also called medical abortion group), and in the same period, 150 healthy pregnant women with a past history of having experienced surgical abortion once were enrolled into the comparison group (also called surgical abortion group). From then on, all the pregnant women in the two groups were followed up till a week after labor. The baseline data of the two groups were comparable (P>0.05). The rates of complications observed in these women during pregnancy and labor were evaluated. RESULTS The incidence rates of miscarriage, placental abnormality, premature delivery and postpartum hemorrhage in the study group were significantly lower than those in the comparison group (P<0.05). No significant differences on other variables were observed between the two groups. CONCLUSION Medical abortion is probably safer than surgical abortion in respect of their influence on subsequent pregnancy. So, provided there is less contraindication, medical abortion may be the choice for terminating unwanted pregnancy, especially for those women without a child.

Abstract
OBJECTIVE To assess the safety of mifepristone in combination with misoprotol for medical abortion. METHOD Literatures on the safety of medical abortion were searched in 9 databases worldwide and 9 Chinese medical journals. RESULTS A total of 101 articles and 1364 women were collected. Severe side effects including allergic or hemorrhagic shock, arrhythmia, convulsion and newborn deformities were observed in 115 cases. A total of 1015 cases appeared vaginal bleeding, mild or moderate allergic reaction. Systematic review found the relative risks (95% confidence interval, CI) of bleeding, abdominal pain, fever and dizziness in the medical abortion population were 3.27 (1.14 - 9.38), 1.63 (1.14 - 2.34), 1.58 (1.03 - 2.44) and 1.36 (1.06 - 1.75), respectively. These were higher in the medical abortion population than that in the surgical abortion population. In addition, the duration of bleeding caused by medical abortion was longer than that caused by surgical abortion. Its weighted mean difference was 6.49 and 95% CI was 6.08 - 7.80. CONCLUSIONS The incidence of side effects caused by this medical abortion was low. However, attention should be paid in clinical practice to the rare, but severe adverse events caused by this treatment. It is necessary to establish a comprehensive nationwide reporting system for these adverse events.

Abstract
OBJECTIVE The number of TOP for medical indications has increased regularly over the last ten years. At the same time, the methods used for TOP have evolved. The purpose of this study was to assess the frequency of complications after drug-induced termination of pregnancy in order to determine whether using this method for interrupting pregnancy during the second or third trimester adds further danger for the mother in terms of early severe risk (uterine rupture, hysterectomy) or less severe long-term risk (infection). MATERIAL AND METHODS This metaanalysis included all articles devoted to pregnancy interruption from 12 gestation weeks retrieved from the Medline database and published between 1989 and 1999 in the United States, Canada, Australia, New Zealand, or the European Union. After excluding articles that included in utero death (n=8), isolated case reports and series involving a high-risk of maternal somatic complications (n=16), and surgical methods for pregnancy termination (n=4), we retained 23 articles for analysis. These articles had included 58,891 drug-induced terminations of pregnancy. For each article, we recorded the following complications: bleeding requiring transfusion, uterine rupture, ovular or placentar retention, and infection. A classical homogenicity test was performed for each type of complication. When this test was not significant, a mean rate, weighing by size of the study, was calculated. RESULTS One study reported maternal deaths (3/143000). The weighted mean rate for late retention (>24 hr) was 1.5 [CI95: 1.1%-1.9%]. For infections, the rates were very variable between studies (from 0.7% to 3.6% with one study reporting 8%). For bleeding with transfusion, the weighted mean rate was 0.7% [CI95: 0.5%-0.9%]. This rate was significantly higher than the rate observed in 1999 in France after delivery excepting medically terminated pregnancy (p<10(-3)) but probably is a reflection of the variable transfusion practices during the eighties in these different countries. Th rate of uterine rupture after medically terminated pregnancy was 0.1% [CI95: 0.07%-0.17%] and would be higher after delivery (excepting terminations) but not significantly (p=0.07). CONCLUSION This metaanalysis demonstrates that the risk of severe complications (uterine rupture and bleeding requiring transfusion) are rare but are more prevalent than after delivery except pregnancy termination. The metaanalysis approach is justified due to the low incidence of these severe complications. A prospective multicentric study of the complications using a geographical base would be useful to obtain unbiased data on risk level. A risk analysis by gestational age, maternal age, parity, and product used would thus be possible, as would long-term monitoring of maternal outcome.
