Abstract
The ductus arteriosus (DA) connects the aorta to the pulmonary artery (PA), directing placentally oxygenated blood away from the developing lungs. High pulmonary vascular resistance and low systemic vascular resistance facilitate shunting of blood in utero from the pulmonary to the systemic circulation through the widely patent DA, thereby optimizing fetal oxygen (O2) delivery. With the transition from fetal (hypoxia) to neonatal (normoxia) oxygen conditions, the DA constricts while the PA dilates. This process often fails in prematurity, promoting congenital heart disease. Impaired O2-responsivness in the DA promotes persistent ductus arteriosus (PDA), the most common form of congenital heart disease. Knowledge of DA oxygen sensing has greatly advanced in the past few decades, however we still lack a complete understanding of the sensing mechanism. The genomic revolution of the past two decades has facilitated unprecedented discovery in every biological system. This review will demonstrate how multiomic integration of data generated from the DA can breathe new life into our understanding of the DA's oxygen response.

Abstract
While cyclooxygenase inhibitors have been the most common medications used to facilitate earlier closure of patent ductus arteriosus in preterm infants, adverse effects and low efficacy in extremely low gestational age neonates (ELGANs) have highlighted a need for alternative options. Combination therapy with acetaminophen and ibuprofen is a novel strategy for PDA treatment in ELGANs, as it may facilitate higher ductal closure rates via additive action on two separate pathways inhibiting prostaglandin production. Initial small observational studies and pilot randomized clinical trials indicate potentially higher efficacy of the combination regime to induce ductal closure in comparison to treatment with ibuprofen alone. In this review, we examine the potential clinical impact of treatment failure in ELGANs with significant PDA, highlight the biological rationale in support of studying combination therapy, and review the randomized and non-randomized studies to date. With the rising number of ELGANs receiving neonatal intensive care, who are vulnerable to PDA-related morbidities, there is an urgent need for adequately powered clinical trials to systematically investigate the efficacy and safety of combination therapy for PDA treatment.

Dual medication therapy (acetaminophen and ibuprofen) for the management of patent ductus arteriosus in preterm infants: a systematic review and meta-analysis. J Perinatol 2022; 42:1654-1661. [PMID: 36008521 DOI: 10.1038/s41372-022-01500-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 08/04/2022] [Accepted: 08/17/2022] [Indexed: 01/19/2023]
Abstract
OBJECTIVE To examine the efficacy of dual medication therapy (intervention) (DMT: acetaminophen and ibuprofen) vs. single medication therapy (control) (SMT: ibuprofen) for medical management of PDA (outcomes) in preterm infants (population). STUDY DESIGN We systematically searched multiple sources to identify randomized controlled trials (RCT) and non-randomized studies (NRS) that compared DMT to SMT for management of hemodynamically significant PDA. RESULTS We identified two RCTs and four NRS. There were no differences in the rates of successful PDA closure following the first treatment course between DMT and SMT (RR = 1.23 [95% CI 0.89-1.70] for NRS and RR = 1.18 [95% CI 0.66-2.10] for RCTs), nor were there significant differences in secondary outcomes and adverse events including PDA ligation, bronchopulmonary dysplasia, and necrotizing enterocolitis etc. Markers of hepatic/renal function did not change significantly during treatment. CONCLUSION We found no evidence for superiority of DMT over SMT in PDA management.

Abstract
To evaluate the efficacy of dual patent ductus arteriosus (PDA) pharmacotherapy compared to monotherapy we searched Medline, Embase, Cochrane Library, and references of relevant articles through October 20, 2021 for randomized clinical trials (RCTs) and cohort studies comparing dual PDA treatment vs. monotherapy. Data were analyzed using a fixed effects model. The fixed effects model assumes that all studies included in a meta-analysis are estimating a single true underlying effect, that of ductal closure. Primary outcome was ductal closure; secondary outcome was surgical ligation. Of 170 articles retrieved, three cohort studies and two RCTs were included, totaling 470 patients: 384 babies received monotherapy and 86 dual therapy. Because of the small numbers, RCTs and cohort studies were pooled for analysis. Ductus closed in 67% of those who received combination compared with 58% those with monotherapy. Overall fixed effect shows an OR of 1.97 [1.10; 3.53; p = 0.023] favoring dual therapy. Dual pharmacologic treatment appears more effective than monotherapy. Future well-powered, high-quality, prospective RCTs are needed to further investigate this potential approach.

Eur J Pediatr 2022; 181:2459-2468. [PMID: 35305143 PMCID: PMC9110525 DOI: 10.1007/s00431-022-04441-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 03/08/2022] [Accepted: 03/09/2022] [Indexed: 02/02/2023]
Abstract
To gain insight in the availability of guidelines, diagnostic criteria, and treatment strategies and whether clinical equipoise regarding optimal treatment for patent ductus arteriosus (PDA) in prematurity is present. We hypothesized that (co-)authors of PDA-related papers were more likely to screen for a PDA and would treat earlier and more aggressively. An international internet-based survey between September 2019 and March 2020 in which we collected (1) baseline characteristics; (2) availability of guidelines; (3) screening strategy for PDA; (4) diagnostic criteria for hemodynamic significance; (5) treatment strategy; and (6) metrics of treatment efficacy. Finally, ten clinical equipoise statements were posed on a Likert scale. In total, 144 surveys were sent, of which 71/144 (49%) surveys could be analyzed with 56/71 (79%) fully completed surveys. The respondents, mainly neonatologists in a level III neonatal intensive care unit, of whom 36/71 (51%) had (co-)authored a publication on the PDA, highlighted a lack of national guidelines, heterogeneous approach to screening strategies, and marked variability in diagnostic criteria to assess hemodynamic significance, treatment strategies and effect measurement. No major significant differences were observed between respondents who did or did not (co-)author a publication on the PDA. Respondents who screened for PDA scored significantly higher on the need for screening, early and aggressive treatment. Remarkably, the scores of all statements regarding clinical equipoise varied widely. Conclusions: Our survey highlights the lack of guidelines and enormous heterogeneity in current practice. Current evidence is not robust enough to harmonize current treatment strategies into (inter)national guidelines. What is Known: • Patent ductus arteriosus (PDA) incidence is inversely related to gestational age. • Although early pharmacological treatment induces PDA closure, optimal treatment is debated due to the lack of beneficial effects on outcome. What is New: • In the absence of (inter)national guidelines, diagnostic and treatment strategies are heterogeneous and contradictory, even in a selected hemodynamically- interested group. • Different PDA screening strategies did, while PDA publication status did not, show significant differences in treatment strategy and responses to equipoise statements.
