RESUMO

SARS-CoV-2 infection has unexpectedly arrived in our society. In pregnant women, the situation has been similar to general population. Some drugs have been used empirically, and obstetricians have to consider whether the same treatments used in the general population were valid for pregnant women with severe disease, according to their safety profile for both the mother and the fetus. There has been a wide experience with the use of hydroxychloroquine and lopinavir/ritonavir in pregnant women. Tocilizumab and interferon beta could be used if benefits exceed risks. There is no experience using remdesivir in pregnancy.


La infección por SARS-CoV-2 ha llegado a nuestra sociedad de forma inesperada. En las mujeres embarazadas, la situación ha sido similar a la de la población general. Algunos fármacos se han utilizado de forma empírica y los obstetras deben considerar si los mismos tratamientos utilizados en la población general son válidos para mujeres embarazadas con enfermedad grave, de acuerdo con su perfil de seguridad tanto para la madre como para el feto. Existe una amplia experiencia con el uso de hidroxicloroquina y lopinavir/ritonavir en mujeres embarazadas. Se podrían usar tocilizumab e interferón beta si los beneficios superan los riesgos. No hay experiencia en el embarazo con remdesivir.

RESUMO

During a pandemic, the three basic principles are. to prioritize medical resources, ensure patients' lockdown in order to avoid community transmission and prevent healthcare collapse, and keep the number of visits to an absolute minimum to avoid patient exposure and safeguard healthcare workers. Antenatal care must be maintained during a health crisis, regardless of the COVID-19 state of alert. Routine and specialist obstetric ultrasound scans are essential for clinical decision-making during pregnancy, as it has a direct impact on the management of mothers and fetuses and on the perinatal outcome. In an attempt to minimize in-person visits, these will be organized according to the established ultrasound schedule. Based on scientific evidence, and on existing main national and international guidelines, this document has been prepared, in which proposals and options are provided for managing pregnant women in the context of the SARS-CoV-2 pandemic. It includes how a Fetal Medicine Unit facing this health crisis should be restructured, what safety measures should be followed in the performance of obstetric scans and invasive procedures, and how ultrasound rooms, equipment and transducers should be cleaned and disinfected. These recommendations should be adapted to different units based on their resources and infrastructure.

RESUMO

AIM OF THE STUDY: The hemodynamic imbalance due to placental vascular anastomoses in TTTS but also vascular changes generated after intrauterine treatment may lead to hypoxic-ischemic complications. Different intestinal complications in TTTS are reviewed in this paper. METHODS: Retrospective review of TTTS cases treated by laser coagulation (LC) from 2012-2015. Demographic data, fetal therapy, prenatal diagnosis (US, MRI) and perinatal outcome were recorded. We describe cases with intestinal complications and their postnatal management. Results are expressed by median and range. RESULTS: 29 monochorionic pregnancies with TTTS were treated (23 LC, 4 cord occlusions and 2 cord occlusions after LC). The diagnosis was made at 19 (16-26) weeks and 86% presented stage of Quintero ≥ II. In 70% of mothers survived at least one fetus with a median of 31 (24-37) weeks at birth. Four patients had intestinal complications (1 jejunal atresia, 2 ileal atresia, 1 perforated necrotizing enterocolitis), half of them had prenatal diagnosis. Postnatal resections of the affected segments and ostomies were performed. Intestinal transit was restored and there were no severe digestive sequelae after 21 (8-38) months of follow up. CONCLUSIONS: Different types of intestinal complications were associated with TTTS and LC. US and MRI enable prenatal diagnosis of these complications and this allows prompt decisions after birth.


INTRODUCCION: El desequilibrio hemodinámico secundario a la presencia de anastomosis vasculares placentarias en el STFF así como los cambios hemodinámicos generados durante y tras su tratamiento mediante fotocoagulación con láser (FC) puede dar lugar a complicaciones hipóxico-isquémicas en distintos sistemas. Revisamos nuestra experiencia en el tratamiento del STFF con FC y presentamos las complicaciones intestinales encontradas. MATERIAL Y METODOS: Estudio retrospectivo de casos tratados intraútero entre 2012 y 2015. Recogimos datos sociodemográficos, terapia fetal, pruebas diagnósticas prenatales (ecografía, RM) y resultados perinatales. Expresamos las medidas en medianas y rangos. RESULTADOS: Se procedió al tratamiento intraútero de 29 gestaciones monocoriales complicadas con STFF (23 FC, 4 oclusiones de cordón y 2 FC seguidas de oclusión). La edad gestacional en el procedimiento fue 19 (16-26) semanas y en el 86% de los casos se trataba de un estadio de Quintero ≥ II. El 70% de las madres tuvieron al menos 1 recién nacido vivo, con mediana de edad gestacional al parto de 31 (24-37) semanas. Presentaron problemas intestinales 4 pacientes (1 atresia yeyunal, 2 atresias ileales, 1 enterocolitis necrotizante con perforación), con sospecha prenatal diagnóstica en 2 de ellos. Postnatalmente se realizó resección del segmento afecto y ostomía. Actualmente se ha restablecido el tránsito intestinal en todos sin secuelas digestivas graves tras 21(8-38) meses de seguimiento. CONCLUSIONES: Hemos descrito distintos tipos de complicaciones intestinales asociadas al STFF y/o su tratamiento con FC. Es posible hacer el diagnóstico prenatal de dichas complicaciones mediante ecografía y RM. Su conocimiento pone al cirujano en alerta y es importante en la toma de decisiones postnatales.

RESUMO

OBJECTIVE: To evaluate whether maintenance treatment with vaginal progesterone after an arrested preterm labour reduces the incidence of preterm delivery. DESIGN: Multicentre, randomised, double-blind, placebo-controlled trial. SETTING: Twelve tertiary care centres in Spain. POPULATION: A total of 265 women with singleton pregnancy, preterm labour successfully arrested with tocolytic treatment, and cervical length of <25 mm. METHODS: Randomisation was stratified by gestational age (from 24.0 to <31.0 weeks of gestation and from 31.0 to <34.0 weeks of gestation) and centre. Patients were randomly assigned, in a 1 : 1 ratio, to either daily vaginal capsules of 200 mg progesterone or placebo until delivery or 36.6 weeks of gestation, whichever occurred first. MAIN OUTCOME MEASURES: Primary outcome was delivery before 34.0 and 37.0 weeks of gestation. Secondary outcomes were discharge-to-delivery time, readmissions because of preterm labour, emergency service use, and neonatal morbidity and mortality. RESULTS: From June 2008 through June 2012, 1419 women were screened: 472 met the inclusion criteria and 265 were randomised. The final analysis included 258 women: 126 in the progesterone group and 132 in the placebo group. There were no significant differences between the progesterone and placebo groups in terms of delivery at <34 weeks of gestation [9/126 (7.1%) versus 10/132 (7.6%), P = 0.91] or <37 weeks of gestation [36/126 (28.6%) versus 29/132 (22.0%), P = 0.22]. There were no differences observed between groups when considering the two strata of gestational age at inclusion. CONCLUSIONS: A maintenance treatment of 200 mg of daily vaginal progesterone capsules in women discharged home after an episode of arrested preterm labour did not significantly reduce the rate of preterm delivery. TWEETABLE ABSTRACT: Maintenance progesterone in 258 women after arrested PTL showed no benefit.

RESUMO

OBJECTIVE: Previous studies have suggested that antiretroviral therapy in human immunodeficiency virus (HIV)-infected pregnant women can cause alterations in cardiac structure and function in fetuses or children, although the results are not very clear. The aim of this study is to assess whether or not these alterations are present in the heart of fetuses of HIV-infected pregnant women, undergoing treatment with highly active antiretroviral therapy (HAART). STUDY DESIGN: We performed a prospective study on 29 consecutive HIV-positive pregnant women treated with HAART and 70 consecutive HIV-negative pregnant women as controls. Fetal cardiac biometry and function was evaluated by echocardiography at 30-32 weeks of gestation. Fetal biometry, estimated fetal weight and umbilical artery Doppler were also measured. RESULTS: We found E/A tricuspid ratio values slightly increased (0.84 vs 0.80, p = 0.03) and diastolic length shortened (49.7 vs 51.7%, p = 0.03) in the HIV-infected group. The rest of the biometric and functional cardiac parameters were not different between both groups. There were no cases of vertical transmission of HIV infection. CONCLUSION: In HIV-infected pregnant women treated with HAART, no significant changes are showed in fetal cardiac parameters.

RESUMO

OBJECTIVE: To evaluate the hypothesis that intrapartum ultrasound (ITU) measurements, including the angle of progression (AOP), progression distance (PD) and head direction (HD), can predict complicated forceps delivery in non-occiput posterior deliveries. METHODS: In this prospective observational study, a single operator performed ITU on 30 patients with an indication for operative forceps delivery. Managing obstetricians were blinded to the results. ITU was performed just before blade application, between contractions and concurrently with contractions and active pushing. Forceps delivery was classified as complicated when one or more of the following situations occurred: three or more tractions; a subjective impression of a difficult or failed application; a third-degree or higher perineal tear; significant bleeding during the episiotomy repair; major tear; significant traumatic neonatal lesion. RESULTS: Twenty-one forceps deliveries were classified as uncomplicated and nine were complicated. The strongest predictor of a complicated forceps delivery, calculated using the area under the receiver-operating characteristics curve (AUC), was the AOP between contractions (AOP1) (AUC = 98.9%). The best cut-off for predicting a difficult forceps delivery was an AOP1 of 138° (sensitivity = 85.7%, specificity = 100%). The best predictive model included both the AOP1 and the HD during a contraction with active pushing (HD2). CONCLUSION: The sonographic parameters AOP and HD can be used to predict complicated operative forceps delivery in fetuses in non-occiput posterior position.

RESUMO

BACKGROUND: Prevalence ofanencephaly in dichorionic twins is higher than in singleton pregnancies. The authors report two cases with two different management strategies. CASE 1: Spontaneous dichorionic diamniotic twin pregnancy with the second twin diagnosed with anencephaly at 12 weeks gestation. Selective feticide was performed at the age of 13.2 weeks. Vaginal delivery occurred at 39 weeks, and birth weight was 2,850 g. CASE 2: Dichorionic diamniotic twin pregnancy discordant for anencephaly in the second twin was diagnosed at 13 weeks gestation. An expectant management was decided. Preterm delivery occurred at 35 weeks due to hydramnios of the affected fetus, delivering a healthy newborn weighing 2,300 g and an anencephalic neonate who died immediately after delivery. CONCLUSION: Anencephaly should be diagnosed as soon as possible, idealistically at 11-13+6 weeks ultrasound (US) scan, in order to offer the most appropriate counselling to the parents, ranging from selective feticide or expectant management. This short series suggests that selective early feticide may increase gestational age and birth weight.

RESUMO

OBJECTIVE: Premature births are a health problem arising in triplet pregnancies, resulting in high levels of morbidity and mortality. The objective of this study is to evaluate the utility of cervical pessaries in reducing prematurity (<34 weeks) in triplet pregnancies. METHODS: This is a single-center, retrospective case-control study regarding triplet pregnancies with follow-up at the La Paz University Hospital between 2000 and 2023. Maternal characteristics, obstetric and perinatal outcomes, and the use of cervical pessaries were examined. RESULTS: 165 triplet pregnancies were analyzed: 87 (52.7 %) in the case group (premature triplet pregnancies) and 78 in the control group (non-premature triplet pregnancies). A cervical pessary was inserted in 15 (17.2 %) triplet pregnancies in the case group and in 12 (16.7 %) triplet pregnancies in the control group (p = 0.92; OR = 1.04 (0.46-2.35)). A pessary was later inserted in the non-premature group (p = 0.01). The risk of preterm labor and the use of tocolytics ± glucocorticoids were found to be significantly more frequent in the premature group, with p = 0.01; OR = 2.30 (1.21-4.36) and p < 0.01; OR = 2.36 (1.23-4.44), respectively. Protocol-based cesarean sections were more frequent in the non-premature group (p < 0.01), while cesarean sections due to maternal complications (p < 0.01) and premature membrane rupture (p < 0.01) were more frequent in the premature group. CONCLUSION: The cervical pessary is not useful in preventing preterm births (< 34 weeks) in triplet pregnancies. It is likely that being pregnant with triplets is a powerful independent factor associated with prematurity, despite other pregnancy conditions. Women who are pregnant with triplets and at risk of preterm labor and those taking tocolytics ± glucocorticoids may benefit from pessary insertion.

RESUMO

OBJECTIVES: There have been significant advances in the medical management of severe postpartum hemorrhage (sPPH) over recent decades, which is reflected in numerous published guidelines. To date, many of the currently available national and international guidelines recommend recombinant factor VIIa (rFVIIa) to be used only at a very late stage in the course of sPPH, as a "last resort", before or after hysterectomy. Based on new safety data, rFVIIa has recently been approved by the European Medicines Agency (EMA) and Swissmedic for use in sPPH, if uterotonics are insufficient to achieve hemostasis, which in fact is significantly earlier in the course of postpartum hemorrhage (PPH). We therefore aimed to develop expert consensus guidance as a step toward standardizing care with the use of rFVIIa for clinicians managing women experiencing life-threatening sPPH. METHODS: The consensus process consisted of one face-to-face meeting with a group of nine experts, including eight obstetrician-gynecologists and a hematologist highly experienced in sPPH care in tertiary care perinatal centers. The panel was representative of multidisciplinary expertise in the European obstetrics community and provided consensus opinion in answer to pre-defined questions around clinical practice with rFVIIa in the management of sPPH. Recommendations have been based on current national and international guidelines, extensive clinical experience, and consensus opinion, as well as the availability of efficacy and new safety data. RESULTS: The expert panel developed 17 consensus statements in response to the 13 pre-defined questions on the use of rFVIIa in the management of sPPH including: available efficacy and safety data and the need for interdisciplinary expertise between obstetricians, anesthesiologists, and hematologists in the management of sPPH. Based on novel data, the experts recommend: (1) earlier administration of rFVIIa in patients with sPPH who do not respond to uterotonic administration to optimize the efficacy of rFVIIa; (2) the importance of hematological parameter prerequisites prior to the administration of rFVIIa to maximize efficacy; and (3) continued evaluation or initiation of further invasive procedures according to standard practice. Furthermore, recommendations on the timing of rFVIIa treatment within the sPPH management algorithm are outlined in a range of specified clinical scenarios and settings, including vaginal delivery, cesarean section, and smaller birthing units before transfer to a tertiary care center. The panel agreed that according to available, and new data, as well as real-world experience, there is no evidence that the use of rFVIIa in patients with sPPH increases the risk of thromboembolism. The authors acknowledge that there is still limited clinical effectiveness data, as well as pharmacoeconomic data, on the use of rFVIIa in sPPH, and recommend further clinical trials and efficacy investigation. CONCLUSIONS: This expert panel provides consensus guidance based on recently available data, clinical experience, and expert opinion, augmented by the recent approval of rFVIIa for use in sPPH by the EMA. These consensus statements are intended to support clinical care for sPPH and may help to provide the impetus and a starting point for updates to existing clinical practice guidelines.

RESUMO

Inflammation is an important component of the metabolic syndrome (MetS) which could be the link between the metabolic and the cardiovascular consequences of this condition. Gestational diabetes mellitus (GDM) has been recognized as a significant risk factor for MetS and an inflammation component has been described in this disease. The aim of the study was to evaluate the relationships between cytokine concentrations, components of MetS and cardiovascular risk markers in women with late-onset GDM. Women (n=63) with late-onset GDM and 63 controls were enrolled. Clinical variables, and obstetrics and perinatal outcomes were recorded. Relationships between cytokines (TNF-α, leptin, IL6, adiponectin) and endothelial injury markers (VCAM, ICAM and selectine) were analyzed. Control vs. patient data indicated: pre-gestational body mass index (BMI) 23.46±3.73 vs. 26.97±5.07kg/m(2) (p=0.001); TNF-α 2.2±0.8 vs. 3.1±1.5pg/mL (p=0.002); leptin 18714.78±8859.08 vs. 27365.79±16209.67pg/mL (p=0.001); adiponectin 162.42±34.19 vs. 141.54±41.33ng/mL (p=0.04). Multivariate analyses showed that adiponectin had a protective effect (OR=0.9; p=0.02) and BMI carried a significant risk (OR=8.4; p=0.01) for GDM. No differences were found in endothelial injury markers. In conclusion, the cytokine profile in women with late-onset GDM is characterized by high concentrations of TNF-α and leptin and low adiponectin. This profile is related, in large extent, to an increased pregravid BMI which, potentially, may be linked to the future development of both metabolic and cardiovascular disease.

RESUMO

OBJECTIVE: To evaluate the usefulness of first trimester fetal head and trunk volume (FHTV) in predicting growth disturbance in twin pregnancy. METHODS: We studied 46 twin pairs from 11 and 14 weeks to delivery. There were 35 dichorionic (76%) and 11 monochorionic (24%) pregnancies. FHTV was assessed by VOCALTM. An inter-twin discrepancy in FHTV, crown-rump length (CRL) and birthweight (BW) were defined by an inter-twin difference greater than 15%. Growth retardation was defined as BW of at least one twin below the 10th percentile. RESULTS: There were 17 cases (37%) of FHTV discrepancy. BW discrepancy and growth retardation were more significantly frequent in cases with FHTV discrepancy than without [11/17 (64.7%) vs 4/29 (13.8%), P = 0.0004 and 7/17 (41.2%) vs 3/29 (10.3%), P = 0.02, respectively]. The detection of BW discordance and growth retardation were significantly higher when using FHTV discordance than CRL discrepancy in the first trimester [11/15 (73%) vs 2/15 (13.3%), P = 0.00001 and 7/10 (70%) vs 1/10 (10%), P = 0.0001, respectively]. CONCLUSION: FHTV discrepancy is a predictor for growth disturbance in twins.

RESUMO

INTRODUCTION: Anti-Ro/SSA and anti-La/SSB antibodies are associated with neonatal lupus and congenital heart block. Controversial results regarding perinatal outcomes are found and less is known about aneuploidy screening. The hypothesis is that the presence of anti-Ro and/or anti-La antibodies influences the levels of PAPP-A and ß-HCG, thus interfering in the calculation of risk of aneuploidies. MATERIAL AND METHODS: Fifty-five anti-Ro/SSA positive pregnant women were included. The demographic characteristics and laboratory variables were studied. Data concerning chromosomopaties screening were also recorded. RESULTS: PAPP-A and ß-HCG levels were calculated (as well as NT and CRL) and compared with a healthy cohort of 12971 pregnant women. PAPP-A levels in mg/mL were lower significatively. In anti-La/SS-B cohort, significant differences were found in PAPP-A in mg/mL and in MoM. Combined risks for Down syndrome (DS) in both groups were higher but the differences were due to age. CONCLUSIONS: Serum levels of PAPP-A were significative lower but not confirmed when adjusted to MoM. This will have to be confirmed in studies with a larger number of patients and to check whether there is an impact in the calculation of DS risk or not. They could represent a group of pregnant women with significantly a higher risk of adverse perinatal outcome. Key Points • Pregnant patients with anti-Ro/SS-A ant/or anti-La/SS-B antibodies have low PAPP-A levels compared with pregnant women without antibodies. • PAPP-A levels are used in obstetrics for aneuploidies screening in the first trimester, so in these patients, there could be more false positive screening. • In these findings are verified in trials with a larger number of patients, a correction variable would have to be applied for the aneuploidies screening calculation. • Also, low PAPP-A levels are correlated with poor placentation, that is to say, more risk of miscarriages, small fetus for gestational age, and preeclampsia. This is another topic to take into consideration in this population.

RESUMO

Chronic histiocytic intervillositis (CHIV) is an uncommon condition, characterized by an infiltrate of mononuclear cells of maternal origin in the intervillous space that has been related to placenta insufficiency and poor perinatal outcomes. The aetiology is unclear, although maternal immunological aggression toward fetal tissues has been proposed. Dermatomyositis (DM) is a multisystem autoimmune inflammatory myopathy. Different autoantibodies have been associated with particular clinical phenotypes; presence of anti-melanoma differentiation-associated gen 5 (MDA5) antibody has been associated with rapidly progressive interstitial lung disease and severe skin lesions, none of which the woman had. Described here is a case of a woman diagnosed with amyopathic DM with positive anti-MDA5 antibodies after two intrauterine fetal deaths. Pathological examination of the placenta in both pregnancies showed CHIV. The presence of a potential relationship between both processes is discussed.

RESUMO

OBJECTIVE: To evaluate ultrasound parameters, including Doppler assessment, that may influence fetal growth and birth weight in cases of isolated single umbilical artery (SUA). METHODS: Sixty pregnant women with isolated SUA were studied. Doppler measurements of umbilical artery (UA), mean uterine artery (UtA) and fetal middle cerebral artery (MCA) pulsatility indices (PI) were recorded and the corresponding Z-scores were calculated according to gestational age at time of measurement. Additionally, the umbilical vein (UV) to UA diameter and perimeter ratios were calculated. The relationships between ultrasound parameters and customized birth-weight centiles according to sex and gestational age were analyzed. RESULTS: There were significant correlations between birth-weight centile and the Z-score of mean UtA-PI (r = - 0.417, P = 0.008) and the UV to UA perimeter ratio (r = 0.567, P = 0.001). A significant positive correlation between Z-scores of UA-PI and mean UtA-PI (r = 0.428, P = 0.007) was also found. When using stepwise linear regression analysis both mean UtA-PI Z-scores and UV to UA perimeter ratio were included in the predictive model of birth-weight centile (R(2) = 0.46, P < 0.001). CONCLUSIONS: Doppler assessment of mean UtA-PI and the UV to UA perimeter ratio may be useful in the clinical management of isolated SUA cases by identifying a subgroup at higher risk for fetal growth restriction.

RESUMO

OBJECTIVE: To evaluate whether maternal diabetes alters the habituation ability of fetuses and newborns. STUDY DESIGN: Two nonrandomized clinical trials were performed. First, we studied prenatal fetuses of women with pregestational diabetes, and control subjects matched for gestational age, and then we studied infants of diabetic mothers (IDM) and control subjects matched for gestational age and mode of delivery. Fetus and newborns were stimulated with vibroacoustic stimulus. RESULTS: In fetuses of diabetic mothers, the ability to habituate was lower, and the habituation rate was higher than in control subjects to all habituation tests. In the neonatal period, ability to habituate was lower (59% vs 100%; P< .001), and the habituation rate was higher (18 [14-21] vs 4 [1.2-6.8]; P< .001) in the IDM than in the control infants. We found a significant negative correlation between maternal glycosylated hemoglobin in each trimester of pregnancy and habituation ability in IDM.

RESUMO

BACKGROUND: Malignant tumours of the vulvar soft tissue are very uncommon. When localized in the Bartholin's gland area these tumours can be mistaken for benign lesions, leading to a delayed diagnosis. CASE: A 52-year-old woman presenting with a vulvar nodule, which was diagnosed as a Bartholin's gland cyst and was referred to the hospital for surgical excision of the lesion. Pathologist report informed of a 6 cm diameter leiomyosarcoma of the vulva with compromised resection margins; extension studies did not suggest any additional lesions and radical hemivulvectomy with ipsilateral inguinal lymphadenectomy was performed. The patient subsequently received radiotherapy and chemotherapy. Twelve months later, a local recurrence was diagnosed and was removed surgically. After 4 years of follow-up the patient remains disease free. CONCLUSION: Any vulvar lesion with unusual characteristics or insidious evolution in labia majora or Bartholin's glands area should be carefully and promptly studied. This is particularly important in order to perform an effective surgical treatment in cases of leiomyosarcoma.
