AbstractObjectiveThe aim of this study was to identify inter-centre differences in persistent ductus arteriosus treatment and their related outcomes.Materials and methodsWe carried out a retrospective, multicentre study including infants between 24+0 and 27+6 weeks of gestation in the period between 2010 and 2011. In all centres, echocardiography was used as the standard procedure to diagnose a patent ductus arteriosus and to document ductal closure.ResultsIn total, 367 preterm infants were included. All four participating neonatal ICU had a comparable number of preterm infants; however, differences were observed in the incidence of treatment (33–63%), choice and dosing of medication (ibuprofen or indomethacin), number of pharmacological courses (1–4), and the need for surgical ligation after failure of pharmacological treatment (8–52%). Despite the differences in treatment, we found no difference in short-term morbidity between the centres. Adjusted mortality showed independent risk contribution of gestational age, birth weight, ductal ligation, and perinatal centre.ConclusionsUsing benchmarking as a tool identified inter-centre differences. In these four perinatal centres, the factors that explained the differences in patent ductus arteriosus treatment are quite complex. Timing, choice of medication, and dosing are probably important determinants for successful patent ductus arteriosus closure.

Abstract Background Controversy exists about the optimal management of a patent ductus arteriosus (PDA) in preterm infants. A persistent PDA is associated with neonatal mortality and morbidity, but causality remains unproven. Although both pharmacological and/or surgical treatment are effective in PDA closure, this has not resulted in an improved neonatal outcome. In most preterm infants, a PDA will eventually close spontaneously, hence PDA treatment potentially increases the risk of iatrogenic adverse effects. Therefore, expectant management is gaining interest, even in the absence of convincing evidence to support this strategy. Methods/design The BeNeDuctus trial is a multicentre, randomised, non-inferiority trial assessing early pharmacological treatment (24–72 h postnatal age) with ibuprofen versus expectant management of PDA in preterm infants in Europe. Preterm infants with a gestational age of less than 28 weeks and an echocardiographic-confirmed PDA with a transductal diameter of > 1.5 mm are randomly allocated to early pharmacological treatment with ibuprofen or expectant management after parental informed consent. The primary outcome measure is the composite outcome of mortality, and/or necrotizing enterocolitis Bell stage ≥ IIa, and/or bronchopulmonary dysplasia, all established at a postmenstrual age of 36 weeks. Secondary short-term outcomes are comorbidity and adverse events assessed during hospitalization and long-term neurodevelopmental outcome assessed at a corrected age of 2 years. This statistical analysis plan focusses on the short-term outcome and is written and submitted without knowledge of the data. Trial registration ClinicalTrials.gov NTR5479.

Abstract Background Patent ductus arteriosus (PDA), the most commonly diagnosed cardiovascular condition in preterm infants, is associated with increased mortality and harmful long-term outcomes (chronic lung disease, neurodevelopmental delay). Although pharmacologic and/or interventional treatments to close PDA likely benefit some infants, widespread routine treatment of all preterm infants with PDA may not improve outcomes. Most PDAs close spontaneously by 44-weeks postmenstrual age; treatment is increasingly controversial, varying markedly between institutions and providers. Because treatment detriments may outweigh benefits, especially in infants destined for early, spontaneous PDA closure, the relevant unanswered clinical question is not whether to treat all preterm infants with PDA, but whom to treat (and when). Clinicians cannot currently predict in the first month which infants are at highest risk for persistent PDA, nor which combination of clinical risk factors, echocardiographic measurements, and biomarkers best predict PDA-associated harm. Methods Prospective cohort of untreated infants with PDA (n=450) will be used to predict spontaneous ductal closure timing. Clinical measures, serum (brain natriuretic peptide, N-terminal pro-brain natriuretic peptide) and urine (neutrophil gelatinase-associated lipocalin, heart-type fatty acid-binding protein) biomarkers, and echocardiographic variables collected during each of first 4 postnatal weeks will be analyzed to identify those associated with long-term impairment. Myocardial deformation imaging and tissue Doppler imaging, innovative echocardiographic techniques, will facilitate quantitative evaluation of myocardial performance. Aim1 will estimate probability of spontaneous PDA closure and predict timing of ductal closure using echocardiographic, biomarker, and clinical predictors. Aim2 will specify which echocardiographic predictors and biomarkers are associated with mortality and respiratory illness severity at 36-weeks postmenstrual age. Aim3 will identify which echocardiographic predictors and biomarkers are associated with 22 to 26-month neurodevelopmental delay. Models will be validated in a separate cohort of infants (n=225) enrolled subsequent to primary study cohort. Discussion The current study will make significant contributions to scientific knowledge and effective PDA management. Study results will reduce unnecessary and harmful overtreatment of infants with a high probability of early spontaneous PDA closure and facilitate development of outcomes-focused trials to examine effectiveness of PDA closure in “high-risk” infants most likely to receive benefit.

Blood flow patterns in the anterior cerebral arteries were studied in eight preterm infants with patent ductus arteriosus and left-to-right shunts. A noninvasive Doppler technique was used to obtain the blood flow patterns and to calculate a pulsatility index. Advancing diastolic blood flow was decreased in all eight infants, and two demonstrated retrograde anterior cerebral artery flow during diastole. Following ductal closure, the diastolic flow in the anterior cerebral arteries increased significantly, reaching levels seen in normal infants. These observations demonstrate that infants with patent ductus arteriosus and left-to-right shunts may have abnormal cerebral hemodynamics which return to normal following ductal closure.

<p><strong>ABSTRACT</strong></p><p><strong>Background: </strong>There is no injectable ibuprofen product marketed to treat patent ductus arteriosus (PDA) in newborns in Canada. The authors’ institution has used ibuprofen arginine in the past. In the absence of published evidence supporting use of this salt form of ibuprofen for neonatal PDA, a retrospective analysis was undertaken.</p><p><strong>Objective: </strong>To compare the effectiveness and adverse effects of ibuprofen arginine, ibuprofen tromethamine, and indomethacin in the treatment of PDA.</p><p><strong>Methods: </strong>This retrospective observational cohort study, for patients admitted between 2009 and 2015, included preterm infants with symptomatic PDA who received at least one dose of injectable indomethacin, ibuprofen tromethamine, or ibuprofen arginine. Three effectiveness end points were analyzed: closure after one course of treatment, repeat medical treatment, and surgical ligation. The secondary end points included acute kidney injury, necrotizing enterocolitis, chronic lung disease, and time to full enteral feeding.</p><p><strong>Results: </strong>A total of 179 infants were included. There were no differences among groups in terms of closure after one course of treatment (37/54 [69%] with indomethacin, 42/70 [60%] with ibuprofen tromethamine, and 28/55 [51%] with ibuprofen arginine; <em>p </em>= 0.21) or surgical ligation (10/54 [19%] with indomethacin, 13/70 [19%] with ibuprofen tromethamine, and 12/55 [22%] with ibuprofen arginine; <em>p </em>= 0.88). However, there was a difference regarding use of a repeat course of treatment, ibuprofen arginine having the highest rate (8/54 [15%] with indomethacin, 18/70 [26%] with ibuprofen tromethamine, and 20/55 [36%] with ibuprofen arginine; <em>p </em>= 0.04). After adjustment for gestational age, the association between ibuprofen arginine and increased use of a repeat course of treatment remained significant. The groups did not differ with respect to adverse effects.</p><p><strong>Conclusion: </strong>These results highlight the potential for differences in effectiveness among various salt forms of injectable ibuprofen and indomethacin. Because of the small sample size and retrospective methodology, confirmation of the present results through a larger prospective study is needed.</p><p><strong>RÉSUMÉ</strong></p><p><strong>Contexte : </strong>Il n’y a pas sur le marché de produit injectable à base d’ibuprofène pour traiter la persistance du canal artériel (PCA) chez le nouveau-né au Canada. L’ibuprofène arginine a été utilisé auparavant dans l’établissement de santé des auteurs. En l’absence de données publiées appuyant l’utilisation de ce médicament sous forme de ce sel pour traiter la PCA chez le nouveau-né, une analyse rétrospective a été réalisée.</p><p><strong>Objectif : </strong>Comparer l’efficacité et les effets indésirables de l’ibuprofène arginine, de l’ibuprofène trométhamine et de l’indométhacine dans le traitement de la PCA.</p><p><strong>Méthodes : </strong>Cette étude de cohorte observationnelle rétrospective, au sujet de patients hospitalisés entre 2009 et 2015, incluait des nourrissons prématurés atteints d’une PCA symptomatique ayant reçu par injection au moins une dose d’indométhacine, d’ibuprofène trométhamine ou d’ibuprofène arginine. Trois paramètres d’évaluation de l’efficacité ont été analysés : la fermeture après un seul traitement, la répétition du traitement médical et la ligature chirurgicale. Les paramètres d’évaluation secondaires étaient les cas d’insuffisance rénale aiguë, d’entérocolite nécrosante et de maladie pulmonaire chronique ainsi que le temps pour atteindre l’alimentation entérale complète.</p><p><strong>Résultats : </strong>Au total, 179 nourrissons ont été admis à l’étude. Aucune différence n’a été relevée entre les groupes en ce qui touche à la fermeture après un seul traitement (37/54 [69 %] pour l’indométhacine, 42/70 [60 %] pour l’ibuprofène trométhamine et 28/55 [51 %] pour l’ibuprofène arginine; <em>p </em>= 0,21) ou à la ligature chirurgicale (10/54 [19 %] pour l’indométhacine, 13/70 [19 %] pour l’ibuprofène trométhamine et 12/55 [22 %] pour l’ibuprofène arginine; <em>p </em>= 0,88). Cependant, une différence a été observée pour ce qui est de la répétition du traitement et l’ibuprofène arginine a obtenu le taux le plus élevé (8/54 [15 %] pour l’indométhacine, 18/70 [26 %] pour l’ibuprofène trométhamine et 20/55 [36 %] pour l’ibuprofène arginine; <em>p </em>= 0,04). Après ajustement pour l’âge gestationnel, l’association entre l’utilisation de l’ibuprofène arginine et une augmentation du recours à un second traitement demeurait significative. Il n’y avait pas de différence entre les groupes en ce qui touche aux effets indésirables.</p><p><strong>Conclusion : </strong>Ces résultats soulignent la possible différence d’efficacité parmi les divers sels d’ibuprofène injectable et l’indométhacine. Cependant, en raison de la petite taille de l’échantillon et de l’emploi d’une méthodologie rétrospective, une étude prospective plus importante doit être menée pour confirmer les résultats de la présente étude.</p>
