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.

<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>

AbstractAimThe aim of this study was to determine the spontaneous closure rate of patent ductus arteriosus at a 2-year follow-up, following failed medical therapy and beyond initial hospital discharge, and to evaluate in-hospital spontaneous or pharmacological closure rates.Materials and methodsA retrospective evaluation was conducted in a cohort of preterm infants admitted to the Neonatal ICU of Ancona between January, 2004 and June, 2013. Inclusion criteria were gestational age between 24+0 and 29+6 weeks or birth weight <1250 g; admission within 48 hours from birth; and discharge alive from hospital. All infants received routine heart ultrasound between 48 and 72 hours of life. Haemodynamically significant patent ductus arteriosus was defined as a duct diameter >1.5 mm, a left atrium-to-aorta ratio >1.4, and/or reversal of end-diastolic flow in the aorta >30% of the anterograde. First-line treatment was intravenous ibuprofen. Intravenous indomethacin was used if ibuprofen failed. Surgical ligation was considered in haemodynamically significant patent ductus arteriosus after medical treatment.ResultsA total of 593 infants met the inclusion criteria, and patent ductus arteriosus was diagnosed in 317 (53.4%). Among them, 283 (89.3%) infants had haemodynamically significant patent ductus arteriosus, with pharmacological closure achieved in 228 (80.6%) infants and surgical ligation performed in 20 (7.1%). Follow-up at 24 months was available for 39 (81.3%) of 48 infants with patent ductus arteriosus at the hospital discharge: 36 (92.3%) underwent spontaneous closure, two (5.1%) underwent surgical ligation, and one (2.6%) had a patent ductus arteriosus.DiscussionA significant number of patent ductus arteriosus that fail pharmacological closure undergo spontaneous closure by the age of 2 years. This information should be taken into account when considering surgery or additional attempts of pharmacological closure.
