RESUMO

OBJECTIVE: Data on obstetric outcomes in patients with a history of immunoglobulin A vasculitis (IgA-V) are lacking. The aim of this study was to assess maternal, neonatal, and vasculitis outcomes during pregnancy. METHOD: We conducted a French retrospective case-control study. Pregnancies of patients with a history of IgA-V (cases) were retrospectively studied and compared to pregnancies in women who developed IgA-V after their pregnancies and to pregnancies in healthy women (controls). RESULTS: Twenty-six pregnancies in patients with a history of IgA-V were included and compared to 15 pregnancies in women who later developed IgA-V and 52 pregnancies in healthy women. Both gestational hypertension and pre-eclampsia were more frequent in the case group than in the other groups (23% vs 0% vs 0%, p < 0.01; 12% vs 7% vs 0%, p = 0.04). Hypertensive disorder of pregnancy occurred more frequently in patients with pre-existing kidney disease (78% vs 12%, p < 0.01). Caesarean section was more often performed in the case group than in the other groups (27% vs 0% vs 10%, p = 0.04). No foetal loss or maternal deaths occurred. There were no differences in delivery term or birth weight. No vasculitis flares were observed during pregnancy. CONCLUSION: Women with a history of IgA-V appear to be at higher risk for gestational hypertension and pre-eclampsia, especially in cases with renal involvement; however, both mother and newborn outcomes appear to be favourable.

RESUMO

OBJECTIVE: To describe and compare the characteristics of women with placenta accreta spectrum (PAS) and their pregnancy outcomes according to the presence of placenta praevia and a prior caesarean section. DESIGN: Prospective population-based study. SETTING: All 176 maternity hospitals of eight French regions. POPULATION: Two hundred and forty-nine women with PAS, from a source population of 520 114 deliveries. METHODS: Women with PAS were classified into two risk-profile groups, with or without the high-risk combination of placenta praevia (or an anterior low-lying placenta) and at least one prior caesarean. These two groups were described and compared. MAIN OUTCOME MEASURES: Population-based incidence of PAS, characteristics of women, pregnancies, deliveries and pregnancy outcomes. RESULTS: The PAS population-based incidence was 4.8/10 000 (95% CI 4.2-5.4/10 000). After exclusion of women lost to follow up from the analysis, the group with placenta praevia and a prior caesarean included 115 (48%) women and the group without this combination included 127 (52%). In the group with both factors, PAS was more often suspected antenatally (77% versus 17%; P < 0.001) and more often percreta (38% versus 5%; P < 0.001). This group also had more hysterectomies (53% versus 21%, P < 0.001) and higher rates of blood product transfusions, maternal complications, preterm births and neonatal intensive care unit admissions. Sensitivity analysis showed similar results after exclusion of women who delivered vaginally. CONCLUSION: More than half the cases of PAS occurred in women without the combination of placenta praevia and a prior caesarean delivery, and these women had better maternal and neonatal outcomes. We cannot completely rule out that some of the women who delivered vaginally had placental retention rather than PAS; however, we found similar results among women who delivered by caesarean. TWEETABLE ABSTRACT: Half the women with PAS do not have both placenta praevia and a prior caesarean delivery, and they have better maternal outcomes.

RESUMO

OBJECTIVE: The long-term morbidity associated with isolated left-sided congenital diaphragmatic hernia (CDH) has been described previously. However, antenatal criteria impacting gastrointestinal morbidity (GIM) are not yet defined. The objective of this study was to evaluate the effect of fetal stomach position on the risk of GIM at 2 years of age in children with left-sided CDH. METHODS: This was a retrospective, observational multicenter cohort study of data obtained from January 2010 to January 2014, that included patients whose fetus had isolated left-sided CDH, with or without fetal endoscopic tracheal occlusion (FETO). Prenatal maternal, fetal and pediatric data were collected. Fetal stomach position was evaluated a posteriori by two observers, using ultrasound images at the level of the four-chamber view of the heart that had been obtained to calculate the observed-to-expected lung-area-to-head-circumference ratio (O/E-LHR). Fetal stomach position was graded as follows: Grade 1, stomach not visualized; Grade 2, stomach visualized anteriorly, next to the apex of the heart, with no structure in between the stomach and the sternum; Grade 3, stomach visualized alongside the left ventricle of the heart, and abdominal structures anteriorly; or Grade 4, as Grade 3 but with stomach posterior to the level of the atrioventricular heart valves. The primary outcome was GIM at 2 years of age, assessed in a composite manner, including the occurrence of gastroesophageal reflux disease, need for gastrostomy, duration of parenteral and enteral nutrition and persistence of oral aversion. Regression analysis was performed in order to investigate the effect of O/E-LHR, stomach position and FETO on various GIM outcome variables. RESULTS: Forty-seven patients with fetal left-sided CDH were included in the analysis. Thirteen (27.7%) infants did not meet the criterion of exclusive oral feeding at 2 years of age. Fetal stomach position grade was associated significantly and independently with the duration of parenteral nutrition (odds ratio (OR), 19.86; P = 0.031) and persistence of oral aversion at 2 years (OR, 3.40; P = 0.006). On multivariate analysis, O/E-LHR was predictive of the need for prosthetic patch repair, but not for GIM. FETO did not seem to affect the risk of GIM at 2 years. CONCLUSION: In isolated left-sided CDH, fetal stomach position is the only factor that is predictive of GIM at 2 years of age. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMO

OBJECTIVE: Morbidity in fetuses affected by gastroschisis is mainly the result of bowel ischaemic and inflammatory processes. Experimental studies on animal models show that clearing amniotic fluid from the digestive secretions by amnioexchange procedures reduces the inflammatory process. We evaluated the benefit of the amnioexchange procedure for fetal gastroschisis in humans. DESIGN: Prospective, interventional, randomised study. SETTING: Eight referral centres for fetal medicine. POPULATION: Pregnant women carrying a fetus with gastroschisis. METHODS: We compared, in utero, amnioexchange with a sham procedure. The protocol included, in both arms, steroid injections at 30 weeks of gestation and the use of postnatal minimal enteral feeding. MAIN OUTCOME MEASURES: The primary outcome was a composite variable based on the duration of ventilation and parenteral nutrition. Secondary outcomes were the effectiveness and safety of the amnioexchange procedure, including the rate of perinatal death, time to full enteral feeding, primary closure, and late feeding disorders. RESULTS: Sixty-four patients were randomised. There was no difference in the composite criteria between the amnioexchange and control groups. Based on an intention-to-treat analysis, there were no significant between-group differences in pregnancy outcome or complications. When studying the relationship between digestive compounds and amniotic fluid inflammatory markers, a clear correlation was found between bile acid and both ferritin and interleukin 1ß (IL1ß). CONCLUSIONS: In humans, amnioexchange, as described in our protocol, is not an option for fetal care; however, we provide supplementary proof of the involvement of inflammation in the pathogenicity of gastroschisis and suggest that future research should aim at reducing inflammation. ClinicalTrials.gov: NCT00127946. TWEETABLE ABSTRACT: A prospective, interventional, randomised study shows no benefit of amnioexchange for fetal gastroschisis in humans.

RESUMO

OBJECTIVE: To assess the efficacy and safety of in-utero aspiration (IUA) of anechoic fetal ovarian cysts. METHODS: This multicenter, prospective, randomized open trial in two parallel groups included women from nine outpatient fetal medicine departments with singleton pregnancy ≥ 28 weeks of gestation and a female fetus with an ultrasound-diagnosed simple ovarian cyst, defined as a single fully anechoic cystic structure measuring ≥ 30 mm. They were allocated randomly to IUA under ultrasound guidance or expectant management. All procedures were performed by trained senior obstetricians. Primary outcome was need for neonatal intervention, by laparoscopy, laparotomy or transabdominal aspiration. Secondary outcomes were in-utero involution of the cyst and oophorectomy at birth. Analyses were conducted according to the intention-to-treat principle. RESULTS: Of 61 participants, 34 were allocated to IUA and 27 to expectant management. Three IUA procedures (9%) could not be performed (one due to fetal position and two due to aspirations being dry). The remaining 31 IUA procedures were uneventful. The incidence of neonatal intervention did not differ significantly between the IUA and the expectant management groups (20.6% vs 37.0%; relative risk (RR), 0.55; 95% CI, 0.24-1.27). Nonetheless, IUA was associated with increased incidence of in-utero involution of the cyst (47.1% vs 18.5%; RR, 2.54; 95% CI, 1.07-6.05) and reduced rate of oophorectomy (3.0% vs 22.0%; RR, 0.13; 95% CI, 0.02-1.03) compared with expectant management. CONCLUSION: IUA of anechoic fetal ovarian cysts, compared with expectant management, was not associated with a reduction in overall neonatal interventions but was associated with a reduced oophorectomy rate.

RESUMO

OBJECTIVE: To analyze the anatomical relationship between the pubic symphysis and the ischial spines to determine reliable landmarks for the assessment of fetal head descent by intrapartum translabial ultrasound (ITU). METHODS: All computed tomography (CT) scans performed for breech presentation and for twin delivery between 2006 and 2014 in a tertiary university hospital were obtained for measurement and analysis by two operators. The symphysis-left ischial spine angle (SIA) and the symphysis-left ischial spine distance (SID) were measured on three-dimensional reconstructions from the CT volume dataset. We calculated intra- and interobserver agreements for SIA and SID with 95% prediction intervals, created Bland-Altman plots with 95% limits of agreement and estimated the intraclass correlation coefficient (ICC). A sagittal plane projection from the SIA enabled calculation of a sagittal angle, corresponding to the angle of progression (AoP) on ITU. RESULTS: SIA and SID were obtained from CT images from 458 women. Reproducibility was good for both SIA (intraobserver ICC, 0.94 (95% CI, 0.88-0.97) and interobserver ICC, 0.81 (95% CI, 0.66-0.92)) and SID (intraobserver ICC, 0.92 (95% CI, 0.82-0.97) and interobserver ICC, 0.83 (95% CI, 0.73-0.92)). The median SIA was 106° (interquartile range (IQR), 105-109°) and median SID was 26.1 (IQR, 23.4-29.5) mm. SIA and SID were not correlated with pelvic diameter or height. The 50th percentile of AoP was 110°. CONCLUSION: Knowledge of the anatomical relationship between the pubic symphysis and ischial spines makes it possible to establish a sonographic method for assesssing fetal head descent by taking into account the level of the ischial spines.

RESUMO

OBJECTIVE: In the first trimester of pregnancy, a biparietal diameter (BPD) below the 5(th) percentile is a simple marker that enables the prenatal detection of half of all cases of open spina bifida. We hypothesized that relating the BPD measurement to the transverse abdominal diameter (TAD) might be another simple and effective screening method. In this study we assessed the performance of using the BPD/TAD ratio during the first trimester of pregnancy in screening for open spina bifida. METHODS: A total of 20,551 first-trimester ultrasound scans (11-13 weeks' gestation), performed between 2000 and 2013, were analyzed retrospectively; there were 26 cases of open spina bifida and 17,665 unaffected pregnancies with a crown-rump length of 45-84 mm and a record of both BPD and TAD measurements. RESULTS: The mean (± SD) BPD/TAD ratio was 1.00 ± 0.06 for fetuses with spina bifida and 1.13 ± 0.06 for those without (P < 0.0001). A BPD ≤ 5(th) percentile enabled the prenatal detection of 46.2% of spina bifida cases, while a BPD/TAD ratio of ≤ 1.00 detected 69.2%. If we considered cases in which either BPD was ≤ 5(th) percentile or BPD/TAD ratio was ≤ 1, we identified 76.9% of cases. In the latter case, the false-positive rate was 5.1%, while that for using a combination of both BPD ≤ 5th percentile and BPD/TAD ratio ≤ 1 was 0.6%, with a sensitivity of 38.5%. The positive predictive value of using a combination of BPD ≤ 5th percentile and BPD/TAD ratio ≤ 1 for detecting spina bifida was 8.5%. CONCLUSIONS: Between 11 and 13 weeks' gestation, relating BPD to TAD improves considerably the diagnostic performance of using BPD measurement alone in screening for open spina bifida. Screening using this marker is simple and applicable to a large population.

RESUMO

Postpartum haemorrhage (PPH) is a major cause of maternal mortality, accounting for one-quarter of all maternal deaths worldwide. Uterotonics after birth are the only intervention that has been shown to be effective for PPH prevention. Tranexamic acid (TXA), an antifibrinolytic agent, has therefore been investigated as a potentially useful complement to this for both prevention and treatment because its hypothesized mechanism of action in PPH supplements that of uterotonics and because it has been proved to reduce blood loss in elective surgery, bleeding in trauma patients, and menstrual blood loss. This review covers evidence from randomized controlled trials (RCTs) for PPH prevention after caesarean (n=10) and vaginal (n=2) deliveries and for PPH treatment after vaginal delivery (n=1). It discusses its efficacy and side effects overall and in relation to the various doses studied for both indications. TXA appears to be a promising drug for the prevention and treatment of PPH after both vaginal and caesarean delivery. Nevertheless, the current level of evidence supporting its efficacy is insufficient, as are the data about its benefit:harm ratio. Large, adequately powered multicentre RCTs are required before its widespread use for preventing and treating PPH can be recommended.

RESUMO

In cases of placenta previa, the distance from the placental edge to the internal os is determinant in deciding on the mode of delivery that will minimize the risk of hemorrhage. The reproducibility and interobserver reliability of this measure are unknown. The internal os is not a point, as two-dimensional (2D) ultrasonography might suggest, but an oval patch that has a measurable width, which may be as wide as the distance separating it from the placenta. It is therefore difficult to determine the exact location of the os using a 2D sectional plane. We report the case of a nulliparous woman admitted for vaginal bleeding at 37 weeks' gestation in whom transvaginal ultrasound examination showed placenta previa, but for which two sonographers reported different measurements for the distance between the placental edge and the internal os. We describe a technique to measure this distance using multiplanar three-dimensional (3D) ultrasound imaging, which allows the smallest distance between the middle of the os and the edge of the placenta, which appears as a line, to be determined. In this case, measurement using 3D ultrasound showed a shorter distance than was suggested by 2D examination. This led us to schedule a Cesarean section delivery, during which there was minimal bleeding. Standardization of 3D measurements should make it possible to define more relevant cut-offs for determining the management of cases of placenta previa.

RESUMO

OBJECTIVE: To identify strategies for reducing neonatal and maternal morbidity associated with intrahepatic cholestasis pregnancy (ICP). MATERIAL AND METHODS: The quality of evidence of the literature was assessed following the GRADE methodology with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS: Of the 14 questions (from 12 PICO questions and one definition question outside the PICO format), there was agreement between the working group and the external reviewers on 14 (100%). The level of evidence of the literature was insufficient to provide a recommendation on two questions. ICP is defined by the occurrence of suggestive pruritus (palmoplantar, nocturnal) associated with a total bile acid level>10µmol/L or an alanine transaminase level above 2N after ruling out differential diagnoses. In the absence of suggestive symptoms of a differential diagnosis, it is recommended not to carry out additional biological or ultrasound tests. In women with CIP, ursodeoxycholic acid is recommended to reduce the intensity of maternal pruritus (Strong recommendation. Quality of the evidence moderate) and to decrease the level of total bile acids and alanine transaminases. (Strong recommendation. Quality of the evidence moderate). S-adenosyl-methionine, dexamethasone, guar gum or activated charcoal should not be used to reduce the intensity of maternal pruritus (Strong recommendation. Quality of evidence low), and there is insufficient data to recommend the use of antihistamines (No recommendation. Quality of evidence low). Rifampicin (Weak recommendation. Very low quality of evidence) or plasma exchange (Strong recommendation. Very low quality of evidence) should not be used to reduce maternal pruritus and perinatal morbidity. Serum monitoring of bile acids is recommended to reduce perinatal morbidity and mortality (stillbirth, prematurity) (Low recommendation. Quality of the evidence low). The level of evidence is insufficient to determine whether fetal heart rate or fetal ultrasound monitoring are useful to reduce perinatal morbidity (No recommendation). Birth is recommended when bile acid level is above 99µmol/L from 36 weeks gestation to reduce perinatal morbidity, in particular stillbirth. When bile acid level is above 99µmol/L is below 100µmol/L, women should be informed that induction of labor could be considered 37 and 39 weeks gestation to reduce perinatal morbidity. (Strong recommendation. Quality of evidence low). In postpartum, total bile acids and alanine transaminases level should be checked and normalized before prescribing estrogen-progestin contraception, ideally with a low estrogen dose (risk of recurrence of pruritus and cytolysis) (Low recommendation. Quality of evidence very low). CONCLUSION: Although the quality of evidence regarding ICP gestational cholestasis remains low, there is a strong consensus in France, as shown by our Delphi study, on how to manage women with ICP. The reference first-line treatment is ursodeoxycholic acid.

RESUMO

CONTEXT: Crohn's disease (CD) and sphincter injury during childbirth are two risk factors for anal incontinence (AI). The long-term risk of developing AI in women with CD after childbirth has never been studied. GOAL: The main objective of the study is to assess the risk of developing severe AI after childbirth in women with CD. METHODS: A retrospective study was performed in women with CD who gave birth in a French "Level 3" maternity hospital between 2000 and 2015. The primary endpoint was severe AI as defined by a Wexner score≥9 or a St. Mark's score≥9, at least five years after childbirth. The association between delivery route and occurrence of severe AI was assessed by univariate and multivariate analyses. RESULTS: Forty-six women were included, 32 of whom were delivered vaginally and 14 by Caesarean section. Thirty-one percent of the women had severe AI according to the Wexner score, and 41% according to the St. Mark's score. Two factors were associated with severe AI: vaginal delivery and the occurrence of an obstetric perineal injury: (crude OR=8.89, 95% (CI: 1.03-76.57) and crude OR=4.16, 95% (CI: 1.06-16.27) respectively for AI defined by the Wexner score, and crude OR=6.8, 95% (CI: 1.30-35.41) and crude OR=4.3, 95% (CI: 1.23-15.2) for AI defined by the St. Mark's score). After adjusting for confounding factors, only vaginal delivery was associated with severe AI (adjusted OR=22.86, 95% CI: 1.52-931.28 for a Wexner score≥9 and adjusted OR=16. 11 (95% CI: 1.43-533.26) for a St Mark score≥9). CONCLUSION: Vaginal birth was associated with the development of severe long-term AI in women with CD.

RESUMO

AIM: To evaluate the nature and frequency of ATP-binding cassette subfamily B member 4 (ABCB4) gene variants in a series of French patients with intrahepatic cholestasis of pregnancy (ICP). METHODS: In this prospective study, the entire ABCB4 gene coding sequence was analysed by DNA sequencing in 50 unrelated women with ICP defined by pruritus and raised serum alanine aminotransferase activity or bile acid concentration, with recovery after delivery. Genomic variants detected in patients with ICP were sought in 107 control pregnant women. Patients with ICP and controls were of Caucasian origin. RESULTS: Eight genomic variants were observed. One nonsense mutation (p.Arg144Stop) and two missense mutations (p.Ser320Phe and p.Thr775Met) were revealed each in one heterozygous patient. A third missense mutation (p.Arg590Gln) was detected in three heterozygous patients and in two homozygous patients also homozygous for a particular haplotype of three single-nucleotide polymorphisms (c.175C>T, c.504T>C, c.711A>T). The chromosomal frequency of the p.Arg590Gln variant was significantly different between the ICP and control group (7.0% vs 0.5%; p = 0.0017; OR 16.03, 95% CI 1.94 to 132.16). An association was also found between allele T of the c.504T>C silent nucleotide polymorphism and ICP (68.0% vs 53.7%; p = 0.017; OR 1.83, 95% CI 1.08 to 3.11). The chromosomal frequency of the p.Arg652Gly variant did not differ between the ICP and control group (p = 0.40). CONCLUSIONS: This study shows that 16% of Caucasian patients with ICP bear ABCB4 gene mutations, and confirms the significant involvement of this gene in the pathogenesis of this complex disorder.

RESUMO

There are no guidelines for the anaesthetic management of caesarean section in women with long QT syndrome; the description of myocardial ventricular repolarisation in healthy women during caesarean delivery could be a first step. The aim of this study was to describe modification of the QT interval, corrected for heart rate, and the interval between the peak and the end of the T-wave (Tpeak-Tend interval) during caesarean section under spinal anaesthesia. We studied 40 patients scheduled for caesarean section under spinal anaesthesia. Patients were randomly assigned to receive either ephedrine or phenylephrine to prevent hypotension. We injected 5 IU oxytocin after delivery. Corrected QT and Tpeak-Tend intervals were unchanged from pre-operative values after induction of spinal anaesthesia, but increased significantly after oxytocin injection. The choice of vasopressor did not affect the Tpeak-Tend interval. The risk-benefit balance of oxytocin bolus during caesarean delivery should be discussed with women with a history of long QT syndrome.

RESUMO

OBJECTIVES: To describe and assess the sonographic findings, evolution and clinical implications of thrombosis of the fetal dural sinuses. METHODS: We compiled a multicenter report of the outcomes of five cases with a prenatal diagnosis of thrombosis of the dural sinuses, and one case in which thrombosis of the dural sinus was diagnosed at necroscopy after termination of pregnancy. Prognostic factors are discussed, and suggestions made for prenatal and postnatal management. RESULTS: The mean (range) gestational age at diagnosis of thrombosis of the dural sinuses in the five cases in which it was made prenatally was 25.2 (22-31) weeks. In these five cases, diagnosis was made by sonography and confirmed by magnetic resonance imaging (MRI), which showed a blood clot in the region of the torcular herophili. Three of the six cases delivered vaginally with favorable sonographic findings, and normal clinical neurological development. Two pregnancies were terminated at the request of the parents. In one of these cases the prognosis was poor, with signs of fetal decompensation or cardiac failure; the pregnancy was terminated and necropsy revealed thrombosis of the occipital dural sinuses associated with a hemangioma. One infant, in whom the thrombosis developed in conjunction with a dural sinus malformation, died at 4 months of age. CONCLUSIONS: Thrombosis of the cerebral venous circulation can occur antenatally and is detectable by fetal real-time and color Doppler ultrasound examination. A review of the literature supports targeted evaluation of the fetus by serial ultrasound imaging and MRI to help guide the diagnosis, and to improve the counseling and management of such cases. Partial or total regression, isolated abnormality, absence of fetal decompensation or signs of cardiac failure and favorable clinical evolution are suggestive of favorable prognosis. In such cases, non-interventional neonatal management is recommended.

RESUMO

Pregnancy in patients with portal hypertension is rare but worrying for the clinician. Although the effects of portal hypertension during pregnancy have not been fully elucidated, there is an evident increase in morbidity, especially associated with cirrhosis, which justifies the idea of at-risk pregnancy and requires management by a multidisciplinary team. The prevention and treatment of gastrointestinal haemorrhage is quite similar to that in nonpregnant patients. Investigation and management of portal hypertension before and at the beginning of pregnancy can reduce the risks of foetal loss, restricted intra-uterine growth, premature birth and maternal mortality, which are closely related to gastrointestinal haemorrhage. The risks related to the underlying disease, such as liver failure with cirrhosis and thromboembolic risk with vascular diseases associated with thrombophilia must be taken into consideration. Generally, vaginal delivery with early analgesics for the mother assisted by an extraction device should be preferred to caesarean section, which must be reserved for obstetrical indications.
