Improvement in fetal pulmonary hypertension and maturity after reversal of ductal constriction: prospective cohort study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2021; 58:420-427. [PMID: 33502049 DOI: 10.1002/uog.23599] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 12/20/2020] [Accepted: 01/20/2021] [Indexed: 06/12/2023]
Abstract
OBJECTIVES To test the hypotheses that estimated mean pulmonary arterial pressure (MPAP) decreases and pulmonary vascular maturation, assessed by the ratio of pulmonary arterial flow acceleration time to ejection time (AT/ET ratio), increases after reversal of fetal ductus arteriosus constriction by reducing maternal intake of the causal agent (prostaglandin inhibitors, such as polyphenol-rich foods or non-steroidal anti-inflammatory drugs), and that these effects are independent of gestational age, which are inferences not yet demonstrated in the clinical setting. METHODS This was a prospective cohort study comparing Doppler echocardiographic ductal flow dynamics, MPAP and pulmonary arterial flow AT/ET ratio in third-trimester fetuses (≥ 28 weeks' gestation) with ductus arteriosus constriction, at the time of diagnosis and after 2 weeks of reduced maternal intake of prostaglandin inhibitors either by suspending the use of pharmacological agents with potential for prostaglandin inhibition or by restricting the consumption of polyphenol-rich foods. MPAP was estimated using the Dabestani equation (MPAP = 90 - (0.62 × AT)), and pulmonary vascular maturity was assessed using the AT/ET ratio, according to reported validation studies. Student's t-test was used for comparison of variables at diagnosis with those after reversal of ductal constriction. Change in MPAP and pulmonary AT/ET ratio between the two assessments was compared with the expected change in the same gestational period in normal fetuses based on reference curves of MPAP and pulmonary AT/ET ratio constructed in normal fetuses from healthy pregnant women at 19-37 weeks' gestation, encompassing the same gestational age range as the study group (28-37 weeks). RESULTS Seventy pregnancies with fetal ductus arteriosus constriction were included in the study. After 2 weeks of reduced maternal intake of prostaglandin inhibitors, normalization of mean systolic (change from 1.86 ± 0.34 m/s at diagnosis to 1.38 ± 0.41 m/s; P < 0.001) and diastolic (change from 0.41 ± 0.11 m/s to 0.21 ± 0.065 m/s; P < 0.001) ductal velocities and of mean pulsatility index (change from 1.99 ± 0.20 to 2.55 ± 0.42; P < 0.001) was demonstrated. MPAP decreased between the assessments (change from 66.7 ± 6.90 mmHg at diagnosis to 54.5 ± 6.70 mmHg after 2 weeks; P < 0.001) and mean pulmonary AT/ET ratio increased (change from 0.20 ± 0.06 to 0.33 ± 0.07; P < 0.001). Change in MPAP between diagnosis and after 2 weeks of reduced maternal intake of prostaglandin inhibitors was -12.2 ± 0.30 mmHg, which was 5.3-times higher than that in 305 normal fetuses over 2 weeks during the same gestational period (-2.3 ± 0.19 mmHg) (P < 0.001), and change in pulmonary AT/ET ratio between the two assessments was 0.13 ± 0.08, which was 8.7-times higher than that in normal fetuses in the same gestational period (0.015 ± 0.08) (P < 0.001). CONCLUSIONS Resolution of fetal ductal constriction is followed by a fall in MPAP and by an increase in pulmonary vascular maturity, to a significantly greater degree than is observed in normal fetuses in the same gestational-age period. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Failure of ductus arteriosus closure after preterm birth is associated with significant morbidities. Ductal closure requires and is regulated by a complex interplay of molecular and mechanical mechanisms with underlying genetic factors. In utero patency of the ductus is maintained by low oxygen tension, high levels of prostaglandins, nitric oxide and carbon monoxide. After birth, ductal closure occurs first by functional closure, followed by anatomical remodeling. High oxygen tension and decreased prostaglandin levels mediated by numerous factors including potassium channels, endothelin-1, isoprostanes lead to the contraction of the ductus. Bradykinin and corticosteroids also induce ductal constriction by attenuating the sensitivity of the ductus to PGE2. Smooth muscle cells of the ductus can sense oxygen through a mitochondrial network by the role of Rho-kinase pathway which ends up with increased intracellular calcium levels and contraction of myosin light chains. Anatomical closure of the ductus is also complex with various mechanisms such as migration and proliferation of smooth muscle cells, extracellular matrix production, endothelial cell proliferation which mediate cushion formation with the interaction of blood cells. Regulation of vessel walls is affected by retinoic acid, TGF-β1, notch signaling, hyaluronan, fibronectin, chondroitin sulfate, elastin, and vascular endothelial cell growth factor (VEGF). Formation of the platelet plug facilitates luminal remodeling by the obstruction of the constricted ductal lumen. Vasa vasorum are more pronounced in the term ductus but are less active in the preterm ductus. More than 100 genes are effective in the prostaglandin pathway or in vascular smooth muscle development and structure may affect the patency of ductus. Hemodynamic changes after birth including fluid load and flow characteristics as well as shear forces within the ductus also stimulate closure. Current pharmacological treatment for the closure of a patent ductus is based on the blockage of the prostaglandin pathway mainly through COX or POX inhibition, albeit with some limitations and side effects. Further research for new agents aiming ductal closure should focus on a clear understanding of vascular biology of the ductus.

Abstract
Background The aim of this systematic review was to describe the effects of drug exposure during pregnancy on fetal cardiac function. Methods We searched MEDLINE, Embase, Cochrane and SCOPUS for studies assessing fetal cardiac function in drug-exposed human pregnancies. Risk of bias was assessed by the Risk Of Bias In Non-randomized Studies of Interventions (ROBIN-I) tool. Results We included 32 studies on eight different drug groups. They included 51 outcome variables, which were all based on ultrasound techniques primarily assessing systolic function: pulsed wave Doppler, tissue Doppler imaging (TDI), and B- and M-mode. Overall, the risk of bias was moderate. β2 agonists increased the systolic velocity in the ductus arteriosus and the fetal heart rate. β-blockers caused unchanged or decreased systolic velocity of the pulmonary trunk. Corticosteroids increased the velocity in the ductus arteriosus. Furthermore, in growth-restricted fetuses with an increased myocardial performance index (MPI') on the right side, corticosteroids normalized this variable. Nonsteroidal anti-inflammatory drugs (NSAIDs), but not acetylsalicylic acid, increased the flow velocities in the ductus arteriosus, decreased the shortening fraction and increased the end-diastolic ventricular diameters. Metformin and insulin normalized the diastolic strain and global longitudinal strain in diabetic pregnancies. Highly active antiretroviral therapy (HAART) exposure increased the E/A ratio on the right side, prolonged the isovolumic relaxation time (IRT) and ejection time, shortened the isovolumic contraction time (ICT), and decreased left myocardial systolic peak velocities. Chemotherapy did not cause detectable changes. Conclusion Six of the eight drug groups caused detectable changes in fetal cardiac function. However, the evidence was hampered by only a few studies for some drugs.

Abstract
BACKGROUND A number of case reports show various outcomes of premature closure of the ductus arteriosus in utero, including persistent pulmonary hypertension of the newborn and fetal or neonatal death; however, no study clarifies the clinical observations that are related to their prognoses. We aimed to clarify the prognostic factors of intrauterine ductal closure by a systematic literature review. Data sources We searched PubMed database (1975-2014) to identify case reports and studies on intrauterine closure of the ductus arteriosus, including maternal, fetal, and neonatal clinical information and their prognoses. RESULTS We analysed the data of 116 patients from 39 articles. Of these, 12 (10.3%) died after birth or in utero. Fetal or neonatal death was significantly correlated with fetal hydrops (odds ratio=39.6, 95% confidence interval=4.6-47.8) and complete closure of the ductus arteriosus (odds ratio=5.5, 95% confidence interval=1.2-15.1). Persistent pulmonary hypertension was observed in 33 cases (28.4%), and was also correlated with fetal hydrops (odds ratio=4.2, 95% confidence interval=1.3-4.6) and complete closure of the ductus arteriosus (odds ratio=5.5, 95% confidence interval=1.6-6.0). Interestingly, maternal drug administration was not correlated with the risk of death and persistent pulmonary hypertension. CONCLUSIONS Fetal hydrops and complete ductal closure are significant risk factors for both death and persistent pulmonary hypertension. Cardiac or neurological prognoses could be favourable if the patients overcome right heart failure during the perinatal period.

Abstract
We report 3 cases of prenatal diagnosis of premature constriction of the ductus arteriosus after maternal benzydamine hydrochloride therapy (3-mg lozenges) in third-trimester pregnancies. In each case, fetal echocardiography revealed a dilated, hypocontractile right ventricle with severe tricuspid regurgitation and constriction of the ductus arteriosus. Although the effect of indomethacin and other nonsteroidal anti-inflammatory drugs on prenatal ductal constriction is well known, readily available over-the-counter nonsteroidal anti-inflammatory drugs such as benzydamine can have an equally deleterious effect and are best avoided in the third trimester of pregnancy.

Abstract
This cross-sectional study in a sample of 887 primigravidae in Rio Branco, Acre State, Brazil aimed to analyze factors associated with the use of medicines during the first pregnancy. Information was obtained from interviews and prenatal cards. Medicines were classified according to the Anatomical Therapeutic Chemical (ATC) Classification System of the World Health Organization and risk categories according to the U.S. Food and Drug Administration. Mean age was 21 years and mean number of medicines used was 2.42. The most frequently consumed medicines were antianemics (47.5%), supplements and vitamins (18.7%), analgesics (13.8%), and antibiotics (10.5%). In the risk categorization, 69.3% belonged to category A, 22.3% to B, 7.6% to C, and 0.8% to D. The odds of having used risky medicines were higher among primigravidae in unit B (OR = 2.10; 95%CI: 1.26-3.50), in the 19 to 24-year age bracket (OR = 2.79; 95%CI: 1.58-4.93), and in the presence of a medical prescription (OR = 1.86; 95%CI: 1.18-2.95). Essential drugs were less used by women with higher family income (OR = 0.63; 95%CI: 0.42-0.96) and those who had received private prenatal care (OR = 0.53; 95%CI: 0.38-0.74).

Abstract
OBJECTIVE Because we have previously demonstrated the relation between polyphenol-rich foods (PRF) consumption and ductus arteriosus constriction, in this work, pregnant sheep were submitted to oral PRF intake for 14 days to understand how this process occurs. Fetal Doppler echocardiography, oxidative and inflammatory biomarkers and total polyphenol excretion were evaluated. RESULTS The high polyphenol intake induced ductus arteriosus constriction by 71.6% increase in systolic (P = 0.001) and 57.8% in diastolic velocities (P = 0.002), and 18.9% decrease in pulsatility index (P = 0.033), along with 1.7-fold increase in total polyphenol excretion, 2.3-fold decrease in inflammatory mediator nitric oxide and following redox status changes (mean ± standard deviation): higher protein carbonyls (1.09 ± 0.09 and 1.49 ± 0.31), catalase (0.69 ± 0.39 and 1.44 ± 0.33) and glutathione peroxidase (37.23 ± 11.19 and 62.96 ± 15.03) in addition to lower lipid damage (17.22 ± 2.05 and 12.53 ± 2.11) and nonprotein thiols (0.11 ± 0.04 and 0.04 ± 0.01) found before and after treatment, respectively. Ductal parameters correlated to NOx , catalase, glutathione peroxidase and protein carbonyl. CONCLUSION Our results highlight the need to reduce maternal PRF intake in late pregnancy to prevent fetal duct constriction through NO-mediated vasoconstrictive action of polyphenols.

Abstract
Fetal circulation has characteristic features, being morphologically and functionally different from extrauterine circulation. The ductus arteriosus plays a fundamental role in directing the blood flow to fetal inferior body parts. Basically, the ductus arteriosus directs 80-85% of the right ventricular output arising from the superior vena cava, coronary sinus, and a small part from the inferior vena cava to descending aorta. Its histological structure is made up predominantly by a thick muscular layer, differently from the aorta and the pulmonary artery, which increases with gestational age. The fibers have a circumferential orientation, especially at the external layers, facilitating and making effective ductal constriction. These factors may generate lumen alterations which may cause fetal and neonatal complications, such as heart failure, hydrops, neonatal pulmonary hypertension, and even death. Classically, maternal administration of indomethacin and/or other antiinflammatory drugs interfere in prostaglandins metabolism, causing ductal constriction. However, many cases of fetal ductal constriction, as well as of persistent neonatal pulmonary artery hypertension, remain without an established etiology, being referred as "idiopathic." In recent years, a growing body of evidence has shown that herbs, fruits, nuts, and a wide diversity of substances commonly used in daily diets have definitive effects upon the metabolic pathway of inflammation, with consequent inhibition of prostaglandins synthesis. This antiinflammatory action, especially of polyphenols, when ingested during the third trimester of pregnancy, may influence the dynamics of fetal ductus arteriosus flow. The goal of this review is to present these new observations and findings, which may influence dietary orientation during pregnancy.

Abstract
Premature constriction or closure of the ductus arteriosus can occur during fetal life. It is a rare phenomenon and has been described secondary to medication or structural lesions or as idiopathic constriction. Premature closure of the ductus arteriosus can lead to progressive right heart dysfunction with tricuspid regurgitation, congestive heart failure, fetal hydrops, and intrauterine death. This series describes diagnosis of fetal ductus arteriosus constriction of unknown etiology in 3 cases, prenatal management, and outcomes. Constriction of the ductus arteriosus can be diagnosed prenatally with careful interrogation of the ductal arch using pulsed Doppler sonography and complete fetal echocardiography. Close monitoring is mandatory to rule out development of right heart failure and to determine the intervention time.

Abstract
A desire for children or the presence of pregnancy limits the drug therapy options for a woman with rheumatoid arthritis. Combination therapies that include methotrexate or new drugs that have not been studied or used in pregnant patients must be excluded, even though they might be highly efficacious. With few exceptions, the reason for this exclusion is not the proven teratogenicity of the drugs, but the absence of proven safety for the fetus. Whereas methotrexate, leflunomide, abatacept and rituximab must be withdrawn before a planned pregnancy, tumor necrosis factor inhibitors and bisphosphonates can be continued until conception. Antimalarial agents, sulfasalazine, azathioprine and ciclosporin are compatible with pregnancy, and so can be administered until birth. Corticosteroids and analgesics such as paracetamol (acetaminophen) can also be used throughout pregnancy. NSAIDs can be safely administered until gestational week 32. The most important consideration when managing rheumatoid arthritis medications during pregnancy is that therapy must be tailored for the individual patient according to disease activity.

Abstract
Prenatal ductal constriction and closure usually are related to maternal intake of prostaglandin receptor inhibitors during late gestation but may occur spontaneously. This report describes three live-born infants sharing echocardiographic features of spontaneous intrauterine ductal constriction, closure, or both, although only one had a prenatal diagnosis. Interestingly, in addition to severely hypertrophied right ventricles, all three had hyperechogenic tricuspid valve papillary muscles. Two also had mild ascending aorta dilation. These cases raise mechanistic questions because of intrauterine ductal occlusion, bright papillary muscles, and potential dilated ascending aortas.
