Abstract
In preterm newborns with extremely low birth weights, patent ductus arteriosus (PDA), which is defined as a remnant connection between the aorta and pulmonary artery after 72 hours of birth, is frequently linked to substantial morbidity and mortality. If left untreated, a hemodynamically significant PDA (hsPDA) increases the risk for bronchopulmonary dysplasia, necrotizing enterocolitis, and intraventricular hemorrhage among other morbidities, and can even lead to death. While instances of patent ductus arteriosus (PDA) resolving on their own are frequent, the primary approach for managing PDA closure in premature infants involves pharmacological interventions, commonly utilizing indomethacin, ibuprofen, or paracetamol. However, with these pharmacological treatment options, there is an increased risk of renal toxicity, gastrointestinal bleeding, and reopening of PDA among other complications. If pharmacological interventions are not successful or contraindicated, PDA can be closed via transcatheter closure or surgical ligation. As with any medically invasive procedure, it is not without risks and can lead to long-term complications. This review explores the different management options and the benefits and outcomes of conservative management vs. active management in order to get one step closer to standardizing the treatment for PDA. With so much controversy surrounding the best management option, there is a lack of evidence to support one treatment method superior to the other in reducing overall mortality, and this needs to be explored further.

Pediatr Res 2023:10.1038/s41390-023-02754-4. [PMID: 37563451 DOI: 10.1038/s41390-023-02754-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/01/2023] [Accepted: 07/09/2023] [Indexed: 08/12/2023]
Abstract
The persistence of a patent ductus arteriosus (PDA) is a common condition in preterm infants with a prevalence inversely proportional to gestational age. PDA is associated with mild-to-severe gastrointestinal complications such as feeding intolerance, gastrointestinal perforation, and necrotizing enterocolitis, which represent a major challenge for the nutritional management in preterm infants. In this context, the Section on Nutrition, Gastroenterology and Metabolism and the Circulation Section of the European Society for Pediatric Research have joined forces to review the current knowledge on nutritional issues related to PDA in preterm infants. The aim of the narrative review is to discuss the clinical implications for nutritional practice. Because there is little literature on postnatal nutrition and PDA in preterm infants, further research with well-designed studies on this topic is urgently needed. Guidelines should also be developed to clearly define the implementation and course of enteral nutrition and the target nutritional intake before, during, and after pharmacologic or surgical treatment of PDA, when indicated. IMPACT: Persistent ductus arteriosus (PDA) is associated with gastrointestinal complications such as feeding intolerance, gastrointestinal perforation, and necrotizing enterocolitis, which pose a major challenge to the nutritional management of preterm infants. In PDA infants, fluid restriction may lead to inadequate nutrient intake, which may negatively affect postnatal growth and long-term health. The presence of PDA does not appear to significantly affect mesenteric blood flow and splanchnic oxygenation after enteral feedings. Initiation or maintenance of enteral nutrition can be recommended in infants with PDA.

Acetaminophen versus indomethacin for patent ductus arteriosus management in premature infants: systematic review and meta-analysis of randomized controlled trials. Paediatr Child Health 2023; 28:291-298. [PMID: 37484043 PMCID: PMC10362965 DOI: 10.1093/pch/pxac130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 12/16/2022] [Indexed: 07/25/2023] Open
Abstract
Objectives Acetaminophen has gained interest in the neonatal community for its use in the management of hemodynamically significant patent ductus arteriosus (HsPDA) in preterm infants. We conducted a systematic review of randomized controlled trials (RCTs) comparing the efficacy and safety of acetaminophen with indomethacin for the management of HsPDA in preterm infants. Methods We searched PROSPERO, OVID Medline, OVID EMBASE, Wiley Cochrane Library (CDSR and Central), EBSCO CINAHL, and SCOPUS from inception to June 15, 2021. Bibliographies of identified studies were searched for additional references. Data were analyzed with Review Manager (RevMan) Version 5.3. Results Four RCTs were identified, enrolling a total of 380 subjects. There was no difference between the interventions for the outcome of PDA closure after one course (RR 1.04 [95% CIs: 0.84, 1.29], P-value 0.70) or after two courses of treatment (RR 1.01 [95% CIs: 0.92, 1.12], P-value 0.77); and for the outcome of PDA ligation (RR 1.56 [95% CIs: 0.48, 5.12], P-value 0.46). However, patients who received acetaminophen had lower rates of necrotizing enterocolitis (RR 0.37 [95% CIs: 0.14, 0.95], P-value 0.04). There were no significant differences noted in the other clinical outcomes, that is, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity requiring treatment, and death. Two studies noted significant post-treatment elevation of serum creatinine and blood urea with indomethacin, as compared to none with acetaminophen use. Conclusions Acetaminophen has comparable efficacy to indomethacin for the outcome of HsPDA closure, with a better safety profile, that is, lesser rates of necrotizing enterocolitis and post-treatment azotemia noted with its use.

Abstract
OBJECTIVE An alternative therapy for preterm infants with a hemodynamically significant patent ductus arteriosus (hsPDA) is needed when cyclooxygenase inhibitors fail or where treatment is contraindicated due to coexisting renal failure, necrotizing enterocolitis, and/or intestinal perforation. No studies have evaluated the efficacy of per rectum (PR) acetaminophen. The study aimed to evaluate the efficacy of PR acetaminophen in modulating the risk of PDA ligation. STUDY DESIGN A retrospective matched case-control study was conducted to compare neonates born <29 weeks' gestation with evidence of hsDA, in an era when rescue rectal acetaminophen was used (January 2014-March 2018) as a treatment strategy, versus historical controls (July 2006-August 2012). All patients underwent comprehensive echocardiography assessment of ductal shunt volume according to a standardized protocol. Acetaminophen treated neonates were matched according to demographics, gestation, preintervention echocardiography features, and comorbidities. Control patients were selected when an echocardiography was performed at an equivalent postnatal age. Infants with a genetic syndrome, severe congenital malformation, or major forms of congenital heart disease excluding small atrial septal defect or ventricular septal defect, PDA, or patent formale ovale were excluded. The primary outcome was surgical ligation of the PDA. Secondary outcomes included echocardiography indices of hemodynamic significance, the composite of death, or severe BPD (defined by ventilator dependence at 36 weeks postmenstrual age). Descriptive statistics and univariate (t-tests, Fisher's exact test, and Mann-Whitney U test) analyses were used to evaluate clinical and echocardiography characteristics of the groups and compare outcomes. RESULTS Forty infants (20 cases and 20 controls), with similar demographic and echocardiography features, were compared. Cases received 6.8 ± 0.7 days (60 mg/kg/day) of PR acetaminophen. Responders (n = 12, 60%) had echocardiography evidence of reduced ductal diameter (2.2 mm [1.9-2.6] to 1.1 mm [0-1.7], p = 0.002), left ventricular output (363 ± 108-249 ± 61 mL/min/kg; p = 0.002) and left atrium to aortic root ratio (1.7 ± 0.3-1.3 ± 0.2; p = 0.002) following treatment. The rate of PDA ligation was 50% lower (p = 0.02) and composite outcome of death or severe bronchopulmonary dysplasia was reduced (p = 0.04) in the acetaminophen group. CONCLUSION Rectal acetaminophen was associated with improvement in echocardiography indices of PDA shunt volume, a 50% reduction in PDA ligation rates and a reduction in the composite outcome of death or severe BPD. Pharmacologic and further prospective clinical studies are needed. KEY POINTS · Many preterm infants encounter the clinical consequences of a hemodynamically significant PDA.. · The merits and optimal timing of PDA ligation remains an area of controversy amongst neonatologists.. · Cyclooxygenase inhibitors are associated with adverse events or are often contraindicated..

Abstract
OBJECTIVE To compare the efficacy of low dose-short course intravenous paracetamol with a conventional dose regimen for early targeted closure of patent ductus arteriosus (PDA). DESIGN Single-centre, double-blinded, active controlled, randomised non-inferiority trial. SETTING Level III neonatal intensive care unit in Western India. PATIENTS Preterm infants <30 weeks of gestation requiring mechanical ventilation, or continuous positive airway pressure with FiO2 ≥0.35 and diagnosed with a haemodynamically significant PDA (hsPDA) at 18-24 hours of postnatal age. INTERVENTIONS Low dose (10 mg/kg/dose 6 hourly for 72 hours) versus conventional dose (15 mg/kg/dose 6 hourly for 120 hours) intravenous paracetamol treatment. MAIN OUTCOME MEASURES Comparison of the rates of ductal closure at completion of sixth postnatal day, using a prespecified non-inferiority margin of 20%. RESULTS A total of 102 infants were enrolled. The median gestational age and birth weight of the included infants were 26.4 weeks and 830 g. At completion of the sixth postnatal day, closure of PDA was achieved in 92% of infants in the low dose group as compared with 94% of those in the standard dose group (risk difference: -1.6%, 95% CI: -11.6% to 8.5%, p=0.38). The rates of rescue therapies, adverse effects and other neonatal morbidities were comparable in both groups. CONCLUSION In very preterm infants on significant respiratory support, low dose-short course intravenous paracetamol treatment was non-inferior to a conventional dosing regime of paracetamol for closure of hsPDA in the first week of postnatal age. Larger studies with narrow margins of non-inferiority are required to confirm our findings. TRIAL REGISTRATION NUMBER CTRI/2017/10/010012.

Abstract
Patent ductus arteriosus (PDA) is a common cardiovascular complication that complicates clinical care in the intensive care of premature infants. Prenatal and postnatal infections and the inflammation process can contribute to PDA, and intrauterine inflammation is a known risk factor of PDA. A variety of inflammatory biomarkers have been reported to be associated with PDA. Chorioamnionitis induces the fetal inflammatory process via several cytokines that have been reported to be associated with the presence of PDA and may have a role in the vascular remodeling process or vessel dilation of the ductus. On the other hand, anti-inflammatory agents, such as antenatal steroids, decrease PDA incidence and severity in patients born to those with chorioamnionitis. Proinflammatory cytokines, which are expressed more significantly in preterm neonates and chorioamnionitis, are associated with the presence of PDA. In this review, we focus on the pathogenesis of PDA in preterm infants and the role of biomarkers associated with the perinatal inflammatory process.

Oral versus intravenous paracetamol for patent ductus arteriosus closure in preterm infants. Pediatr Res 2022; 92:1146-1152.

Abstract
BACKGROUND To examine whether oral administration of paracetamol as a first-line agent had a greater effect on the closure of a patent ductus arteriosus than the intravenous route. METHODS We performed a retrospective study of preterm infants (<37 weeks of gestation) between 2012 and 2020 treated with oral or intravenous paracetamol as the first line for patent ductus arteriosus (PDA) constriction and compared rates of ductal closure, course duration, cumulative dose, PDA characteristics, and serum levels. RESULTS Over the study period, 80 preterm infants received paracetamol, of which 50 received paracetamol as first-line treatment to augment constriction of the PDA. Closure rate was higher in the oral group (n = 15/19, 79%) compared to the intravenous group (n = 8/20, 40%, p < 0.01), and remained significant after adjusting for gestational age, length of treatment, and postnatal age (OR 0.14, 95% CI 0.03-0.67, p = 0.014, RR 0.51, 95% CI 0.28-0.91). Eleven preterm infants received a combination of both oral and intravenous paracetamol with a closure rate of 45% (n = 5). CONCLUSIONS Oral administration of paracetamol as a first-line agent is more efficacious to constrict the PDA than the intravenous route, irrespective of gestational age or course duration. IMPACT Our retrospective study comparing the use of oral versus intravenous paracetamol as the first line for patent ductus arteriosus (PDA) constriction in preterm infants demonstrates that oral administration of paracetamol is more efficacious to constrict the PDA than the intravenous route, irrespective of gestational age or course duration. To our knowledge, this is the first published study (prospective or retrospective) to compare the efficacy of oral versus intravenous paracetamol as a first-line treatment for PDA closure in preterm infants. Our finding may improve the rate of PDA closure when paracetamol is used as a first-line agent.

Abstract
Over the past decade, clinicians have increasingly prescribed acetaminophen (APAP) for patients in the neonatal intensive care unit (NICU). Acetaminophen has been shown to reduce postoperative opiate burden, and may provide similar efficacy for closure of the patent ductus arteriosus (PDA) as nonsteroidal anti-inflammatory drugs (NSAIDs). Despite these potential benefits, APAP exposures have spread to increasingly less mature infants, a highly vulnerable population for whom robust pharmacokinetic and pharmacodynamic data for APAP are lacking. Concerningly, preclinical studies suggest that perinatal APAP exposures may result in unanticipated adverse effects that are unique to the developing lung. In this review, we discuss the clinical observations linking APAP exposures to adverse respiratory outcomes and the preclinical data demonstrating a developmental susceptibility to APAP-induced lung injury. We show how clinical observations linking perinatal APAP exposures to pulmonary injury have been taken to the bench to produce important insights into the potential mechanisms underlying these findings. We argue that the available data support a more cautious approach to APAP use in the NICU until large randomized controlled trials provide appropriate safety and efficacy data.

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.

Abstract
Background and objective: Hemodynamically significant patent ductus arteriosus (hsPDA) can cause ductal steal and contribute to poor outcomes in preterm infants. Near-infrared spectroscopy (NIRS) allows us to continuously evaluate regional tissue oxygenation (rSpO2) and perfusion changes in underlying organs. The aim of this study was to evaluate the effect of medical treatment for hsPDA on cerebral and renal rSpO2 in infants less than 32 weeks of gestational age, and older than 72 h of life. Materials and methods: Infants with a gestational age of <32 weeks with hsPDA were prospectively studied before and during medical treatment. Two-site (cerebral and renal) rSpO2 monitoring by NIRS was performed 1 h before treatment (T0) and 24 h (T1), 24−48 h (T2), 48−72 h (T3) after the infusion of the first drug dose. Results: A total of 21 infants were studied. The mean day of life at treatment initiation was 8.2 (SD, 2.75). The DA diameter, LA/Ao ratio, and resistive index in the anterior cerebral artery (RI ACA) were significantly lower after treatment (p < 0.05). There were no significant differences in cerebral rSpO2, cerebral fractional tissue oxygen extraction (FTOE), and SpO2 comparing different time points. A significantly higher renal SpO2 value was recorded at T2 as compared with T0 (75.0%, SD 4.9%, vs. 69.4%, SD 7.6%; p < 0.013), while for renal FTOE, a tendency to lower values at T2 was observed (0.18, SD 0.05, vs. 0.24, SD 0.09; p = 0.068). Conclusions: Late (later than 7 days postpartum) hsPDA medical treatment with paracetamol or ibuprofen completely closed the duct only in a small proportion of preterm infants, despite a statistically significant reduction in the DA diameter, LA/Ao ratio, and RI ACA. Continuous renal, not cerebral, NIRS measurements can help to anticipate the efficacy of medical treatment of hsPDA in preterm infants. Large-scale prospective studies are needed to ascertain that renal and cerebral NIRS can be used as a reliable tool for evaluating the effectiveness of medical treatment for hsPDA.

Abstract
Objective: To systematically review the efficacy and safety of oral Acetaminophen for premature infants with patent ductus arteriosus (PDA). Methods: Databases including Ovid, EMbase, Pubmed, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINHAL), China National Knowledge Infrastructure (CNKI), Chinese Biomedical Database (CBM), WanFang Data, China Science and Technology Journal Database were searched to collect the randomized controlled trials (RCTs) about Acetaminophen for premature infants with PDA from inception to January 1, 2021. Quality assessment was performed through bias risk evaluation according to the Cochrane Handbook 5.1.0, and then the homogeneous studies were analyzed using Revman 5.4 software. Results: A total of 16 RCTs were included, which were divided into for four subgroups: subgroup I (oral acetaminophen vs. oral ibuprofen, 13 RCTs), subgroup II (oral acetaminophen vs. intravenous indomethacin, 1 RCT), subgroup III (oral acetaminophen vs intravenous ibuprofen, 1 RCT), and subgroup IV (oral acetaminophen vs intravenous placebo, 1 RCT). In subgroup I, There was no significant difference in the ductal closure rate after the first course of drug administration [typical relative risk (RR) 0.97, 95% confidence interval (CI) 0.90 to 1.05], the accumulated ductal closure rate after two course of treatment (RR 0.96, 95% CI 0.91–1.02), and mortality (RR 1.06, 95% CI 0.75–1.49) between treatment with oral acetaminophen versus oral ibuprofen (p > 0.05); compared with oral ibuprofen, oral acetaminophen was associated with a significant reduction in the incidence of gastrointestinal bleeding/stool occult blood positive (RR 0.51, 95% CI 0.32 to 0.82)and oliguria (RR 0.62, 95% CI 0.42–0.91) (p < 0.05). Conclusion: The meta analysis approves the facts that there is no significant difference in the efficacity in premature infants with PDA between oral acetaminophen and buprofen or indometacin, but compared to ibuprofen, oral acetaminophen may decrease the incidence of oliguria and gastrointestinal bleeding. More reliable conclusions should be made through large-size, multi-center, well-designed RCTs.

Abstract
Background: Patent ductus arteriosus (PDA) is one of the more common congenital heart defects in preterm neonates. The closure of PDA can be done with ibuprofen; however, this drug is associated with many contraindications and potential side-effects. In the past years, paracetamol has been proposed for the treatment of PDA. This study was designed to evaluate the efficacy and gastrointestinal complications of paracetamol and ibuprofen for the pharmacological closure of PDA in preterm infants. Methods: In a clinical trial study, 40 preterm infants with echocardiographically confirmed PDA were randomly assigned to receive either paracetamol (n = 23; 15 mg/kg every 6 h for 2 days) or ibuprofen (n = 17; initial dose of 10 mg/kg, followed by 5 mg/kg every 12 h for 2 days). The neonates matched for gestational age and weight. We used t-test for parametric, Chi-square for categorial, and Wilcoxson for nonparametric variables. Significant level was considered less than 0.05. Results: Platelet count, BUN and creatinine levels, and closure of PDA had not significant difference between two groups (P > 0.05). Incidence and severity of GI bleeding, feeding intolerance, and NEC were significantly more in infants who received paracetamol than ibuprofen (P < 0.05). Conclusions: There were no differences in the rate of PDA closure between the two drugs, but with respect to complications, rate and severity of GI bleeding, feeding intolerance, and NEC were significantly more in infants who received paracetamol than ibuprofen. Therefore, paracetamol could not be used as a proper alternative agent for ibuprofen in the treatment of PDA in preterm infants.

Abstract
OBJECTIVE The purpose of the study was to quantify cost savings after promoting oral pharmacotherapy for the treatment of hemodynamically significant patent ductus arteriosus (hsPDA). METHODS This was a retrospective before-and-after time series quality improvement study. Oral ibuprofen and acetaminophen use criteria were developed and recommended, rather than the more costly intravenous equivalents. There were 24-month medication use reports generated for both the pre-criteria (Era-1) and the post-criteria (Era-2) implementation phases to identify neonates prescribed hsPDA medications in order to assess cost differences. RESULTS Era-1 had 190 treatment courses in 110 neonates for a total medication cost of $171,260.70. Era-2 had 210 courses in 109 patients for a total medication cost of $47,461.49, yielding savings of $123,799.21 ($61,899.61 annually) after criteria implementation. The reduction in intravenous ibuprofen use in Era-2 accounted for all the savings. CONCLUSION Preferentially prescribing lower-cost oral medications to treat hsPDA led to significant cost savings.

Abstract
Objectives The aim of this study was to collect consistent data on the efficacy and safety and evaluation hepatotoxicity of intravenous acetaminophen for the treatment of PDA in preterm infants. Methods This is an observational longitudinal prospective study on 46 preterm infants with PDA who treated with high dose of acetaminophen and evaluated with echocardiography and serum liver enzymes at Hafez and Zeinabiyeh hospitals from January 2016 to December 2019. Result Forty-six preterm infants with PDA treated with intravenous acetaminophen. Rate of closure of PDA was 82.6. There was no significant difference after treatment regarding AST, ALT, Albumin, total and direct bilirubin (P value > 0.05) and no adverse side effects were observed in association with intravenous acetaminophen. Conclusion High dose of acetaminophen is not more effective than that with standard doses although without hepatotoxic side effect for PDA closure.

Abstract
The patent ductus arteriosus (PDA) is the most commonly found cardiac condition in neonates. While there have been several studies and thousands of publications on the topic, the decision to treat the PDA is still strongly debated among cardiologists, surgeons, and neonatologists. This is in part due to the shortage of long-term benefits with the interventions studied. Practice variations still exist within sub-specialties and centers. This article briefly summarizes the history, embryology and histology of the PDA. It also succinctly discusses the hemodynamic significance of a PDA which builds the framework to review all the available literature on PDA closure in premature infants, though not a paradigm shift just yet; it introduces transcatheter PDA closure (TCPC) as a possible armament to the clinician for this age-old problem.

Abstract
INTRODUCTION Association between persistency of a patent ductus arteriosus (PDA) and morbidity in preterm newborns is still controversial. We aimed to investigate the relation between PDA and morbidity in a large retrospective study. METHODS A case-control study including neonates consecutively admitted to the Neonatal Intensive Care Unit (NICU), with gestational age (GA) < 32 weeks or body birth weight (BW) < 1500 g, over a 5-year period. Newborns were divided into Cases and Controls, according with the presence or absence of a hemodynamically significant PDA (hs-PDA). RESULTS We enrolled 85 Cases and 193 Controls. Subjects with hs-PDA had significantly (p < 0.001) lower GA (26.7 w, 95%CI 27.1-28.0 vs. 30.1 w, 95%CI 29.7-30.4), BW (1024 g, 95% CI 952-1097 vs. 1310 g 95%CI 1263-1358) and an increased morbidity (60.0% vs. 18.7%). In a sub-group of extremely preterm newborns (GA ≤ 28 weeks and BW ≤ 1000 g), the rate of bronchopulmonary dysplasia (BPD) was significantly increased in Cases (31.7%) compared with Controls (5.9%, p = 0.033). Multivariate analysis showed that morbidity significantly depended on hs-PDA, GA and BW, and that, in extremely preterms, the hs-PDA represented an independent risk factor for BPD. CONCLUSIONS Occurrence of the main morbidities of prematurity depended by hs-PDA, in association with GA, BW, and use of prenatal steroids. In extremely premature babies, hs-PDA is a risk factor for BPD, one of the most important morbidity of prematurity, independently by other confounding variables.

Abstract
Objective was to compare the rate of successful treatment of hsPDA based on echocardiogram criteria after use of IV acetaminophen or IV indomethacin in very low-birthweight infants. The study was a multi-center, randomized controlled trial. Infants born prior to 32 weeks with birthweight ≤ 1500 g were included if PDA treatment was indicated within the 21 days after birth. hsPDA was defined by strict echocardiogram criteria. Eligible infants were randomized to treatment with either IV acetaminophen or IV indomethacin. Of 86 eligible infants, 17 infants were randomized to acetaminophen and 20 to indomethacin. One (5.9%) hsPDA in the acetaminophen group had successful treatment compared to 11 (55%) in the indomethacin group (p = 0.002). Eight (47%) in the acetaminophen group and 3 (15%) in the indomethacin group received transcatheter PDA closure (p = 0.07). IV indomethacin was more effective than IV acetaminophen for treatment of hsPDAs. More infants in the acetaminophen group received transcatheter closure.

Abstract
Introduction: There are still uncertainties about the timing and indication for surgical ligation of patent ductus arteriosus (PDA) in pre-term infants, where lower gestational age (GA) usually is predictive for surgical treatment. Objective: Our aim was to assess differences in clinical characteristics and outcomes between surgically treated and matched non-surgically treated PDA in extremely pre-term infants. Methods: All extremely pre-term infants born 2010-2016 with surgically treated PDA (Ligated group; n = 44) were compared to non-surgically treated infants (Control group; n = 44) matched for gestational age (+/-1 week) and time of birth (+/-1 month). Perinatal parameters, echocardiographic variables, details of pharmacological PDA treatment, morbidity, and mortality were assessed. Result: Mean GA and birthweight were similar between the Ligated group (24+5 ± 1+3 weeks and 668 ± 170 g) and the Control group (24+5 ± 1+3 weeks and 704 ± 166 g; p = 1.000 and p = 0.319, respectively). Infants in the Ligated group had larger ductal diameters prior to pharmacological treatment, and lack of diameter decrease and PDA closure after treatment (p = 0.022, p = 0.043 and 0.006, respectively). Transfusions, post-natal steroids and invasive respiratory support were more common in the Ligated group. Except for a higher incidence of severe bronchopulmonary dysplasia (BPD) in the Ligated group there were no other differences in outcomes or mortality between the groups. Conclusion: Early large ductal diameter and reduced responsiveness to pharmacological treatment predicted the need for future surgical ligation in this matched cohort study of extremely pre-term infants where the effect of GA and differences in treatment strategies were excluded. Besides an increased incidence of severe BPD in the Ligated group, no other differences in morbidity or mortality were detected.

Abstract
OBJECTIVE In preterm infants, the standard pharmacologic treatment for a hemodynamically significant patent ductus arteriosus (hsPDA) is either ibuprofen or indomethacin. However, these medications may be less effective after 2 weeks of age. We investigated the use of acetaminophen in hsPDA closure beyond 2 weeks of age. METHODS An observational study of 11 infants, <30 weeks' gestation at birth and postnatal age > 2 weeks, who received acetaminophen treatment for their hsPDA. Echocardiograms (ECHOs), B-type natriuretic peptide (BNP) levels, and the fraction of inspired oxygen (FiO2) were obtained before and after treatment to analyze ductal characteristics. Renal and liver functions were monitored pretreatment and posttreatment to look for potential medication side effects. RESULTS Of the 10 infants with ECHO data for before and after acetaminophen treatments, 4/10 (40%) had a decrease in PDA size, with no infants having complete closure immediately posttreatment. Eight of 11 (73%) infants had a decreased FiO2 requirement after treatment. Of the 5 infants with pretreatment and posttreatment BNP data, 2/5 (40%) infants had a decrease in BNP level. One infant received an additional course of acetaminophen. Four infants underwent a surgical ligation. Two infants died. No medication side effects occurred with regard to hepatic and renal function. CONCLUSION Acetaminophen is a safe and effective pharmacologic treatment to reduce the significance of the hsPDA in some infants beyond 2 weeks of age, as shown by ECHO and BNP data.

Oral Paracetamol vs Oral Ibuprofen in Patent Ductus Arteriosus: A Randomized, Controlled, Noninferiority Trial. J Pediatr 2020; 222:79-84.e2. [PMID: 32336479 DOI: 10.1016/j.jpeds.2020.01.058] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 12/26/2019] [Accepted: 01/28/2020] [Indexed: 01/01/2023]
Abstract
OBJECTIVE To test the hypothesis that oral paracetamol is non-inferior to oral ibuprofen in closing hemodynamically significant patent ductus arteriosus (hsPDA) with an a priori noninferiority (NI) margin of 15%. STUDY DESIGN Multicenter, randomized, controlled, NI trial conducted in level III neonatal intensive care units. Consecutively inborn preterm neonates of <32 weeks of gestation with hsPDA were included. Those with structural heart disease, major malformations, and contraindications for enteral feeding or for administration of study drugs were excluded. Interventions included oral paracetamol in the experimental arm and oral ibuprofen in the active control arm. The primary outcome was closure of hsPDA by 24 hours from the last dose of the study drug. Secondary outcome measures included closure of hsPDA by 24 hours after the first course of the study drug, rate of reopening after the first course, and adverse events associated with the study drug. RESULTS Out of 1250 neonates screened, 161 were randomized. Oral paracetamol was noninferior to oral ibuprofen in closure of hsPDA by both per protocol analysis (62 [95.4%] vs 63 [94%]; relative risk [RR], 1.01 [95% CI, 0.94-1.1]; risk difference [RD], 1.4 [95% CI, -6 to 9]; P = .37) and intention-to-treat analysis (63 [89%] vs 65 [89%]; RR, 0.99 [95% CI, 0.89-1.12]; RD, -0.3 [95% CI, -11 to 10]; P = .47). All adverse events were comparable in the 2 study arms. CONCLUSIONS Oral paracetamol is noninferior to oral ibuprofen for the closure of hsPDA in preterm neonates of <32 weeks of gestation. No difference was observed in the adverse events studied.

Acetaminophen increases pulmonary and systemic vasomotor tone in the newborn rat. Pediatr Res 2020; 87:1171-1176.

Abstract
BACKGROUND Acetaminophen is widely prescribed to both neonates and young children for a variety of reasons. In adults, therapeutic usage of acetaminophen induces systemic arterial pressure changes and exposure to high doses promotes tissue toxicity. The pulmonary vascular effects of acetaminophen at any age are unknown. Hypothesizing that, early in life, it promotes vasomotor tone changes via oxidative stress, we tested the in vitro acetaminophen effects on intrapulmonary and carotid arteries from newborn and adult rats. METHOD We measured the acetaminophen dose-response in isometrically mounted arteries and pharmacologically evaluated the factors accounting for its vasomotor effects. RESULTS Acetaminophen induced concentration- and age-dependent vasomotor tone changes. Whereas a progressive increase in vasomotor tone was observed in the newborn, the adult arteries showed mostly vasorelaxation. Inhibition of endogenous nitric oxide generation with L-NAME and the use of the peroxynitrite decomposition catalyst FeTPPS (Fe(III)5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrinato chloride) mostly abolished the drug-induced increase in newborn pulmonary vasomotor tone CONCLUSIONS: In newborn rats, acetaminophen increases pulmonary vasomotor tone via peroxynitrite generation. Given its therapeutic usage, further clinical studies are warranted to assess the acetaminophen effects on the newborn pulmonary and systemic vascular resistance.

Abstract
BACKGROUND We previously reported in a randomised trial that early intravenous paracetamol accelerated contraction of ductus arteriosus in very preterm infants (<32 gestation weeks). AIMS To monitor sequentially paracetamol effects on the blood pressure and brain tissue oxygenation in the infants participating the trial. METHODS In a double-blind trial, intravenous paracetamol or placebo was infused to 48 very premature infants starting within 24 h of birth for four days. Besides the ductus arteriosus, we systematically measured blood pressure, peripheral (spO2) and regional cerebral oxygen saturation (rcSO2), and cerebral fractional tissue oxygen extraction (cFTOE) during the study period. RESULTS Compared to the placebo, the paracetamol loading dose transiently decreased the arterial blood pressure. During treatment, the paracetamol-treated infants had higher spO2 (p = .042) and rcSO2 (p = .036) values than the placebo group infants. Additionally, the cFTOE values were lower in the paracetamol group during the study without statistical significance. All infants with closed ductus had higher tissue oxygenation and a lower cFTOE than infants with open ductus. CONCLUSIONS Paracetamol caused modest haemodynamic effects and increased cerebral oxygenation. They were mostly due to early contraction of ductus. Additional direct drug-effects in brain are not ruled-out.

Abstract
Objective To compare effectiveness and safety of combination therapy (acetaminophen and ibuprofen) to monotherapy (ibuprofen, indomethacin, or acetaminophen alone) in treatment of the patent ductus arteriosus (PDA) in premature neonates. Methods This was a retrospective cohort study of neonates admitted to a tertiary-level neonatal intensive care unit. Included neonates were born at <32 weeks gestation and received pharmacotherapy for PDA closure. Based on the primary therapy received, our cohort was divided into the following four groups: indomethacin alone, ibuprofen alone, acetaminophen alone, and ibuprofen and acetaminophen (in combination). Baseline characteristics, effectiveness, safety, neonatal mortality, and morbidities rates between these groups were compared. Results One hundred and forty neonates were analyzed; 17 received combination therapy, and 123 neonates received monotherapy: 22 (17.9%) ibuprofen, 29 (23.6%) acetaminophen, and 72 (58.5%) indomethacin. The PDA closure rates were 41.7% for indomethacin, 41.2% for combination therapy, 37.9% for acetaminophen, and 31.8% for ibuprofen (P=0.100). Rates of adverse effects were comparable between the groups. Conclusion The rate of ductal closure was not different between combination therapy and monotherapy. The study did not demonstrate any increased adverse effects in the combination group. Future well-designed prospective clinical trials are needed to guide clinical practice.

Abstract
Background The optimal management of PDA in very low birth weight (VLBW) infants is still controversial. Aim of our study was to investigate the management of PDA in the Italian neonatal intensive care units (NICU). Methods We conducted an on-line survey study from June to September 2017. A 50-items questionnaire was developed by the Italian Neonatal Cardiology Study Group and was sent to Italian NICUs. Results The overall response rate was 72%. Diagnosis of PDA was done by neonatologists, cardiologists or both (62, 12 and 28% respectively). PDA significance was assessed by a comprehensive approach in all centers, although we found a heterogeneous combination of parameters and cut-offs used. None used prophylactic treatment. 19% of centers treated PDA in the first 24 h, 60% after the first 24 h, following screening echocardiography or clinical symptoms, 18% after the first 72 h and 2% after the first week. In the first course of treatment ibuprofen, indomethacin and paracetamol were used in 87, 6 and 7% of centers respectively. Median of surgical ligation was 3% (1–6%). Conclusions Significant variations exist in the management of PDA in Italy. Conservative strategy and targeted treatment to infants older than 24 h with echocardiographic signs of hemodynamic significance seemed to be the most adopted approach.

Abstract
BACKGROUND In preterm newborns, the ductus arteriosus frequently fails to close and the infants require medical or surgical closure of the patent ductus arteriosus (PDA). A PDA can be treated surgically; or medically with one of two prostaglandin inhibitors, indomethacin or ibuprofen. Case reports suggest that paracetamol may be an alternative for the closure of a PDA. An association between prenatal or postnatal exposure to paracetamol and later development of autism or autism spectrum disorder has been reported. OBJECTIVES To determine the effectiveness and safety of intravenous or oral paracetamol compared with placebo or no intervention, intravenous indomethacin, intravenous or oral ibuprofen, or with other cyclo-oxygenase inhibitors for treatment of an echocardiographically diagnosed PDA in preterm or low birth weight infants. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 10), MEDLINE via PubMed (1966 to 6 November 2017), Embase (1980 to 6 November 2017), and CINAHL (1982 to 6 November 2017). We searched clinical trial databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials (RCT) and quasi-randomised trials. SELECTION CRITERIA We included RCTs in which paracetamol was compared to no intervention, placebo or other agents used for closure of PDA irrespective of dose, duration and mode of administration in preterm (≤ 34 weeks' postmenstrual age) infants. We both reviewed the search results and made a final selection of potentially eligible articles by discussion. We included studies of both prophylactic and therapeutic use of paracetamol. DATA COLLECTION AND ANALYSIS We performed data collection and analyses in accordance with the methods of the Cochrane Neonatal Review Group. We used the GRADE approach to assess the quality of evidence for the following outcomes when data were available: failure of ductal closure after the first course of treatment; neurodevelopmental impairment; all-cause mortality during initial hospital stay (death); gastrointestinal bleed or stools positive for occult blood; and serum levels of creatinine after treatment (µmol/L). MAIN RESULTS We included eight studies that reported on 916 infants. One of these studies compared paracetamol to both ibuprofen and indomethacin. Five studies compared treatment of PDA with paracetamol versus ibuprofen and enrolled 559 infants. There was no significant difference between paracetamol and ibuprofen for failure of ductal closure after the first course of drug administration (typical risk ratio (RR) 0.95, 95% confidence interval (CI) 0.75 to 1.21; typical risk difference (RD) -0.02, 95% CI -0.09 to 0.09); I² = 0% for RR and RD; moderate quality of evidence. Four studies (n = 537) reported on gastrointestinal bleed which was lower in the paracetamol group versus the ibuprofen group (typical RR 0.28, 95% CI 0.12 to 0.69; typical RD -0.06, 95% CI -0.09 to -0.02); I² = 0% for RR and RD; number needed to treat for an additional beneficial outcome (NNTB) 17 (95% CI 11 to 50); moderate quality of evidence. The serum levels of creatinine were lower in the paracetamol group compared with the ibuprofen group in four studies (moderate quality of evidence), as were serum bilirubin levels following treatment in two studies (n = 290). Platelet counts and daily urine output were higher in the paracetamol group compared with the ibuprofen group. One study reported on long-term follow-up to 18 to 24 months of age following treatment with paracetamol versus ibuprofen. There were no significant differences in the neurological outcomes at 18 to 24 months (n = 61); (low quality of evidence). Two studies compared prophylactic administration of paracetamol for a PDA with placebo or no intervention in 80 infants. Paracetamol resulted in a lower rate of failure of ductal closure after 4 to 5 days of treatment compared to placebo or no intervention which was of borderline significance for typical RR 0.49 (95% CI 0.24 to 1.00; P = 0.05); but significant for typical RD -0.21 (95% CI -0.41 to -0.02); I² = 0 % for RR and RD; NNTB 5 (95% CI 2 to 50); (low quality of evidence). Two studies (n = 277) compared paracetamol with indomethacin. There was no significant difference in the failure to close a PDA (typical RR 0.96, 95% CI 0.55 to 1.65; I² = 11%; typical RD -0.01, 95% CI -0.09 to 0.08; I² = 17%) (low quality of evidence). Serum creatinine levels were significantly lower in the paracetamol group compared with the indomethacin group and platelet counts and daily urine output were significantly higher in the paracetamol group. AUTHORS' CONCLUSIONS Moderate-quality evidence according to GRADE suggests that paracetamol is as effective as ibuprofen; low-quality evidence suggests paracetamol to be more effective than placebo or no intervention; and low-quality evidence suggests paracetamol as effective as indomethacin in closing a PDA. There was no difference in neurodevelopmental outcome in children exposed to paracetamol compared to ibuprofen; however the quality of evidence is low and comes from only one study. In view of concerns raised regarding neurodevelopmental outcomes following prenatal and postnatal exposure to paracetamol, long-term follow-up to at least 18 to 24 months' postnatal age must be incorporated in any studies of paracetamol in the newborn population. At least 19 ongoing trials have been registered. Such trials are required before any recommendations for the possible routine use of paracetamol in the newborn population can be made.

Abstract
Background Although indomethacin and ibuprofen are the standard treatments for hemodynamically significant patent ductus arteriosus (hsPDA), they are associated with renal impairment and gastrointestinal complications. Paracetamol for hsPDA closure does not provoke a peripheral vasoconstrictive effect and seems to have effects similar to those of indomethacin and ibuprofen. We have previously reported the safety of low-dose (7.5 mg/kg) intravenous paracetamol for preterm infants with hsPDA, who were indomethacin-resistant or -contraindicated but did not affect the need for surgical PDA ligation. However, reports considering the use of higher-dose (15 mg/kg) paracetamol for hsPDA have not been published in Japan. Cases In 16 premature infants in whom indomethacin or ibuprofen was contraindicated or ineffective, 15 mg/kg of paracetamol was intravenously administered every 6 hours for 3 days after obtaining parental consent. hsPDA closure or narrowing was observed in 14 infants (88%), with the need for surgical closure totally avoided in nine cases (56%). High plasma paracetamol levels were observed in three cases. No paracetamol-related side effects or adverse events were reported. Conclusion The intravenous administration of higher dose paracetamol was safe and feasible in premature infants with hsPDA. Future clinical trials to explore the optimized dose and timing of administration are needed.

Abstract
Introduction: Echocardiography (ECHO) with color flow Doppler is considered as the gold standard to identify a hemodynamic patent ductus arteriosus (hs-PDA). However, the optimal diagnostic and therapeutic management for newborns with hs-PDA is still controversial. We aimed to investigate two clinical strategies: (1) targeted treatment based on ECHO criteria and (2) treatment based on ECHO criteria in addition to clinical signs and symptoms. Materials and Methods: This is a cohort study including all neonates consecutively admitted in the Neonatal Intensive Care Unit of University La Sapienza in Rome, with gestational age <32 weeks or body birth weight <1,500 g and with a diagnosis of hs-PDA as confirmed by ECHO evaluation performed within 72 h of life. We classified the babies in two cohorts: (A) pharmacological treatment immediately after ECHO screening and (B) pharmacological therapy for PDA was administered when the relevance of a hs-PDA was associated with clinical signs of hemodynamic instability. Results: We considered as primary outcome newborns who survived without any morbidities (A: 48.1% vs. B: 22.2%, p = 0.022). In particular, we found that the rate of intraventricular hemorrhage stage ≥2 was increased in cohort B (A: 3.7% vs. B 24.4%, p = 0.020). A multivariate analysis showed that assignment to cohort A independently influences the primary outcome. Conclusions: Adopting an hs-PDA management option based on ECHO-directed therapy regardless of symptoms may reduce the morbidity and improve the survival of very low birth weight infants.

Abstract
Background: Currently, the first line treatment of persistent ductus arteriosus (PDA) is either indomethacin or ibuprofen. However, the potentially life-threatening side effects associated to their use have prompted physicians to look for alternative options. The incorporation of paracetamol as an alternative to ibuprofen in the management of PDA is still based on insufficient clinical evidence. Hence, more clinical trials are needed to establish a therapeutic role for paracetamol in the management of PDA that take into consideration short- and long-term safety and efficacy outcomes. Study Design: This is a non-inferiority, randomized, multicenter, double-blinded study to evaluate the efficacy, and safety of intravenous (IV) paracetamol vs. IV ibuprofen (standard treatment) for PDA in preterm patients with a gestational age ≤ 30 weeks. At baseline, patients will be randomized (1:1) to treatment with paracetamol or ibuprofen. The primary endpoint is closure of the ductus after the first treatment course. Secondary endpoints are related to effectiveness (need for a second treatment course, rescue treatment, reopening rate, time to definitive closure, need for surgical ligation), safety (early and long-term complications), pharmacokinetics, and pharmacodynamics, pharmacogenetics, pharmacoeconomics, and genotoxicity. Long-term follow-up to 24 months of corrected postnatal age will be performed using Bayley III neurodevelopmental scale. Trial Registration: ClinicalTrials.gov Identifier: NCT04037514. EudraCT: 2015-003177-14.

To Feed or Not to Feed: A Critical Overview of Enteral Feeding Management and Gastrointestinal Complications in Preterm Neonates with a Patent Ductus Arteriosus. Nutrients 2019; 12:nu12010083. [PMID: 31892190 PMCID: PMC7019993 DOI: 10.3390/nu12010083] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 12/19/2019] [Accepted: 12/24/2019] [Indexed: 12/20/2022] Open
Abstract
The management of enteral feeds in preterm infants with a hemodynamically significant patent ductus arteriosus (hs-PDA) is a major challenge for neonatologists due to the fear of gastrointestinal (GI) complications. This review aims to analyze the available evidence on the complex relation between the presence and management of PDA, enteral feeding practices, and GI outcomes in the preterm population. There is limited evidence, based on small and heterogeneous trials, that hs-PDA may affect the splanchnic hemodynamic response to enteral feeds. While the presence of PDA seems a risk factor for adverse GI outcomes, the benefits of feeding withholding during pharmacological PDA treatment are controversial. The lack of robust evidence in support of or against a timely feeding introduction or feeding withholding during pharmacological PDA closure in preterm neonates does not allow to draw any related recommendation. While waiting for further data, the feeding management of this population should be carefully evaluated and possibly individualized on the basis of the infants’ hemodynamic and clinical characteristics. Large, multicentric trials would help to better clarify the physiological mechanisms underlying the development of gut hypoperfusion, and to evaluate the impact of enteral feeds on splanchnic hemodynamics in relation to PDA features and treatment.

Abstract
Objective: The purpose of this review is to present the available literature on the use of nonopioid analgesics such as nonsteroidal anti-inflammatory drugs in postcardiac surgery pediatric patients, mainly to focus on patients <1 year of age, and to provide the foundation for future research. Materials and Methods: Published studies that address the use on nonopioid medications for postoperative sedation and analgesia in infants and children undergoing cardiac surgery were identified from online sources. Studies were reviewed by two authors independently to assess the quality of the data as well as the evidence. Due to limited availability of such studies, the review was then expanded to include use in noncardiac procedures as well as to expanded age groups. All studies that met the primary objective were included. Results/Data Synthesis: Majority of the studies in the population of interest were related to use of ketorolac. Five studies specifically addressed ketorolac use in cardiac patients. In addition, studies were reviewed for nonopioid analgesia in noncardiac patients and included as a part of the available evidence as in the case of acetaminophen use. Newer agents as well as agents with very limited information were also acknowledged. Conclusion: Nonopioid medications appear to show promise for analgesia in infants undergoing cardiac surgery, with ketorolac being the most potent agent as a potential substitute for opioids. These agents demonstrate a reasonable safety profile even in the very young. There continue to be significant gaps in knowledge before their adoption becomes routine. However, gives the awareness regarding short-term and long-term impact of opioid use in this vulnerable population, and studies of such agents are an urgent need.

Abstract
Background: Patent ductus arteriosus (PDA) is a common cause of morbidity in premature neonates. The purpose of this study was to compare the efficacy of oral ibuprofen and oral acetaminophen to closure of symptomatic PDA, in premature neonates with gestational age (GA) ≤32 weeks. Materials and Methods: This study was a randomized clinical trial with forty preterm neonates who were admitted in neonatal intensive care unit with symptomatic PDA and GA ≤32 weeks or birth body weight ≤1500 g. Twenty neonates received oral acetaminophen [Group A] and twenty neonates received oral ibuprofen [Group B] and compared with echocardiography finding each groups for closed PDA before and after treatment regiment. Results: Our results showed that the primary closure rate of PDA was 70% (95% confidence interval [CI]: 49.9%–90%) and 65% (95% CI: 54.3%–75.7%) in the acetaminophen and ibuprofen groups, respectively, and statistically no significant difference was observed between the two groups (P = 0.74). Conclusion: These findings suggest that there was no significant difference between the effectiveness of oral acetaminophen and oral ibuprofen on closing of PDA, but less adverse effects and contraindication for acetaminophen make it reasonable choice for the treatment of symptomatic PDA.

Patent ductus arteriosus in preterm infants: is early transcatheter closure a paradigm shift? J Perinatol 2019; 39:1449-1461.

Abstract
The optimal management approach of the patent ductus arteriosus (PDA) in premature infants remains uncertain owing the lack of evidence for long-term benefits and the limited analyses of the complications of medical and surgical interventions to date. In recent years, devices suitable to plug the PDA of premature infants (including extremely low birthweight, <1000 g) have become available and several trials have demonstrated successful and safe transcatheter PDA closure (TCPC) in this population. Whether TCPC represents a paradigm shift in PDA management that will result in improved short- and long-term outcomes, less bronchopulmonary dysplasia, improved neurodevelopment, or better long term renal function remains to be seen. Careful rigorous study of the potential benefits of TCPC in this highly vulnerable population in the context of well-designed adequately powered trials is needed prior to widespread adoption of this approach.

Abstract
INTRODUCTION The optimal management of patent ductus arteriosus (PDA) remains contentious. The medications used to treat PDA are often non-steroidal anti-inflammatory drugs, which are associated with a number of unwanted adverse effects. Paracetamol is a medication with an excellent safety profile in infants and has been suggested as a safe alternative medication in situations where other medications have failed or are contraindicated. There are limited data on the use of early, intravenous paracetamol in preterm infants. METHODS AND ANALYSIS This trial aims to address whether early treatment with paracetamol will reduce the number of infants requiring intervention for PDA. This is a randomised, double-blind, placebo-controlled trial in preterm infants <29 weeks' gestation. At 6 hours of life, infants with a ductus arteriosus >0.9 mm will be randomised to receive either (1) intravenous paracetamol at a dose of 15 mg/kg initially, followed by every 6 hours at a dose of 7.5 mg/kg for 5 days; or (2) intravenous 5% dextrose every 6 hours for 5 days. The primary outcome is the need for any intervention for management of PDA up to 5 days. Secondary outcomes include closure of the ductus arteriosus at 5 days, size of the ductus arteriosus, ductal reopening, systemic blood flow, mortality and significant morbidities. The target sample size of 100 infants yields >80% power, at the two-sided 5% level significance, to detect a 50% reduction in the need for intervention assuming that approximately 60% of infants in this study would otherwise have required intervention for PDA. ETHICS AND DISSEMINATION A report on the results of the planned analyses will be prepared. The results of the primary analysis of all end points will be presented at medical conferences and submitted for publication in peer-reviewed journals. Separate manuscripts pertaining to the second aim of the study may be written, and these will also be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER ACTRN12616001517460.

Recently Registered Midazolam Doses for Preterm Neonates Do Not Lead to Equal Exposure: A Population Pharmacokinetic Model. J Clin Pharmacol 2019; 59:1300-1308. [PMID: 31093992 PMCID: PMC6767398 DOI: 10.1002/jcph.1429] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Accepted: 04/04/2019] [Indexed: 11/11/2022]
Abstract
Although midazolam is a frequently used sedative in neonatal intensive care units, its use in preterm neonates has been off-label. Recently, a new dosing advice for midazolam for sedation on intensive care units has been included in the label (0.03 mg/[kg·h] for preterm neonates <32 weeks and 0.06 mg/[kg·h] for neonates >32 weeks). Concentration-time data of a prospective multicenter study (29 patients, median gestational age 26.7 [range 24.0-31.1 weeks]) were combined with previously published data (26 patients, median gestational age 28.1 [range 26.3-33.6 weeks]), and a population pharmacokinetic model describing the maturation of midazolam pharmacokinetics was developed in NONMEM 7.3. Clearance was 73.7 mL/h for a neonate weighing 1.1 kg and changed nonlinearly with body weight (exponent 1.69). Volume of distribution increased linearly with body weight and was 1.03 L for a neonate weighing 1.1 kg. Simulations of the newly registered dosing show considerable differences in steady-state concentrations in preterm neonates. To reach similar steady-state concentrations of 400 µg/mL (±100 µg/mL), a dose of 0.03 mg/(kg·h) is adequate for neonates ≥1 kg and ≤2 kg but would have to be reduced to 0.02 mg/(kg·h) (-33%) in neonates <1 kg and increased to 0.04 mg/(kg·h) (+33%) in neonates weighing >2 kg and ≤2.5 kg. The impact of the observed differences in exposure is difficult to assess because no target concentrations have yet been defined for midazolam, but the current analysis shows that one should be cautious in giving dosage advice based on historical data with a lack of reliable pharmacokinetic and effect data.

Abstract
OBJECTIVE To evaluate the effectiveness of drugs used to constrict patent ductus arteriosus (PDA) in newborns < 28 weeks. METHODS We performed a secondary analysis of the multi-center PDA-TOLERATE trial (NCT01958320). Infants with moderate-to-large PDAs were randomized 1:1 at 8.1 ± 2.1 days to either Drug treatment (n = 104) or Conservative management (n = 98). Drug treatments were assigned by center rather than within center (acetaminophen: 5 centers, 27 infants; ibuprofen: 7 centers, 38 infants; indomethacin: 7 centers, 39 infants). RESULTS Indomethacin produced the greatest constriction (compared with spontaneous constriction during Conservative management): RR (95% CI) = 3.21 (2.05-5.01)), followed by ibuprofen = 2.03 (1.05-3.91), and acetaminophen = 1.33 (0.55-3.24). The initial rate of acetaminophen-induced constriction was 27%. Infants with persistent moderate-to-large PDA after acetaminophen were treated with indomethacin. The final rate of constriction after acetaminophen ± indomethacin was 60% (similar to the rate in infants receiving indomethacin-alone (62%)). CONCLUSION Indomethacin was more effective than acetaminophen in producing ductus constriction.

Abstract
Introducción. Por lo general, el manejo farmacológico del conducto arterioso permeable (CAP) comprende inhibidores no selectivos de la enzima ciclooxigenasa, en especial indometacina e ibuprofeno. En años recientes también se ha sugerido al acetaminofén como alternativa terapéutica.Objetivo. Realizar una revisión narrativa de la literatura acerca del manejo farmacológico del CAP.Materiales y métodos. Se realizó una búsqueda estructurada de la literatura en las bases de datos ProQuest, EBSCO, ScienceDirect, PubMed, LILACS, Embase, Trip Database, SciELO y Cochrane Library con los términos “Ductus Arteriosus, patent AND therapeutics”; “Ductus Arteriosus, patent AND indometacin”; “Ductus Arteriosus, Patent AND ibuprofen”, y “Ductus Arteriosus, patent AND acetaminophen”. La búsqueda se hizo en inglés con sus equivalentes en español.Resultados. Se encontraron 69 artículos con información relevante para llevar a cabo la presente revisión.Conclusiones. En neonatos prematuros, la base del tratamiento farmacológico del CAP continúa siendo los inhibidores no selectivos de la ciclooxigenasa, indometacina e ibuprofeno, ambos con perfiles similares de seguridad y eficacia. La evidencia disponible sugiere que el acetaminofén podría constituir una alternativa útil para el manejo, pero resulta insuficiente para realizar recomendaciones definitivas respecto a la eficacia y seguridad de este medicamento.

Abstract
OBJECTIVE To explore the efficacy and risks of oral paracetamol in later (>2 weeks old) treatment of patent ductus arteriosus (PDA). STUDY DESIGN A multicentre double-blind placebo-controlled randomised pilot trial in three neonatal intensive care units in Australia. Infants born <33 weeks with haemodynamically significant PDA were treated with a 5-day course of oral paracetamol or placebo. Cardiac ultrasounds were used to document haemodynamic parameters. The primary outcome analysed was ductal closure by 48 h after treatment completion. Secondary outcomes included reduction in ductal diameter >25% and safety. RESULTS Fifty-five infants were enrolled, of whom 27 received paracetamol and 28 placebo. Eighty percent had received previous non-steroidal anti-inflammatory drug. Mean postnatal age was 25 days. Four of the 27 ducts treated with paracetamol closed vs. 0/28 treated with placebo (p = 0.05). An additional 13/27 given paracetamol vs. 7/28 given placebo showed significant constriction (p = 0.008). No adverse effects were observed . CONCLUSIONS There was some evidence of increased closure with oral paracetamol at postnatal age >2 weeks; however, the overall efficacy was not high.

Abstract
Background: Indomethacin and ibuprofen, two commonly used prostaglandin inhibitors, are the drugs of choice for patent ductus arteriosus. However, paracetamol is an alternative choice when these drugs are ineffective or contraindicated. This study aimed to confirm paracetamol's efficacy and safety compared with those of other drugs or placebos for patent ductus arteriosus closure in premature infants. Methods: We conducted a literature search using the Cochrane Library, PubMed, CINAHL, and EMBASE databases for randomized controlled trials and quasi-randomized controlled trials. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to direct the process and PICO (P, population; I, intervention/interest; C, comparator; O, outcome) principle to constitute the theme. We combined the research data through qualitative summaries or meta-analyses. Results: The final analyses included 15 trials (N = 1,313). No significant differences were noted between paracetamol and ibuprofen except for shorter mean days needed for patent ductus arteriosus closure, lower risk of gastrointestinal bleeding, and hyperbilirubinemia. No significant difference existed between paracetamol and indomethacin. Oral paracetamol was more effective than placebo in infants weighing 1,501-2,500 g. Conclusions: Our study findings tentatively conclude that paracetamol can induce early patent ductus arteriosus closure without significant side effects but that its efficacy is not superior to that of indomethacin.

Quantitation of paracetamol by liquid chromatography-mass spectrometry in human plasma in support of clinical trial. Future Sci OA 2018; 4:FSO331. [PMID: 30271617 PMCID: PMC6153454 DOI: 10.4155/fsoa-2018-0039] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2018] [Accepted: 06/25/2018] [Indexed: 02/05/2023] Open
Abstract
Aim: Paracetamol is a well-tolerated antipyretic widely used in severe malaria management. The study aimed to develop and validate a rapid LC–MS/MS assay to quantify paracetamol in plasma from patients with severe malaria. Materials & methods: Plasma sample was precipitated by organic solvent containing isotope-labeled paracetamol internal standard. Supernatant was isolated, diluted with water, followed by LC–MS/MS analysis. Results: Plasma samples were extracted and assayed in less than 5.5 min. The assay response was linear (0.125–50 mg/l) with total intra- and interassay imprecision of <1.4%, which were considerably lower than most published reports. Conclusion: We developed, validated and applied a rapid and small volume LC–MS/MS assay with high precision and accuracy for plasma paracetamol quantitation in 989 samples from 62 patients with severe malaria. The simple and high-throughput quality could facilitate assay automation for future clinical studies. Paracetamol is a commonly prescribed antipyretic in severe malaria management. Here, a rapid quantitative assay was developed to measure the plasma level of paracetamol. The developed method required levels as low as 20 μl plasma, and was highly precise, with a short analysis time of 5.5 min. The developed method is particularly suitable for clinical trial application and potentially for clinical use.

Photoplethysmographic assessment of pulse transit time correlates with echocardiographic measurement of stroke volume in preterm infants with patent ductus arteriosus. J Perinatol 2018; 38:1220-1226. [PMID: 29961764 DOI: 10.1038/s41372-018-0165-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2018] [Revised: 05/25/2018] [Accepted: 06/11/2018] [Indexed: 11/09/2022]
Abstract
OBJECTIVE We aimed to correlate photoplethysmographic parameters with stroke volume in infants with PDA. Photoplethysmography constitutes the optical signal in pulse oximetry. STUDY DESIGN Stroke volume was determined echocardiographically. Pulse transit time, right hand to foot arrival time difference, and relative amplitude were measured from pulse oximeter and ECG waveforms. Photoplethysmographic parameters before and after PDA closure were compared with stroke volume. RESULTS After PDA closure, pulse transit time to the hand and to the foot were prolonged (54.7 ± 6.7 vs 65.5 ± 9.8 ms, p < 0.001, 82.5 ± 12.8 vs 88.6 ± 10.6 ms, p = 0.03), arrival time difference decreased (27.7 ± 7.6 vs 23.1 ± 5.6 ms, p = 0.021), and relative amplitude decreased (from 2.1 ± 0.7% to 1.5 ± 0.5%, p = 0.003). The time-based photoplethysmographic parameters correlated with stroke volume. CONCLUSIONS Photoplethysmographic waveform parameters are significantly different before and after PDA closure and the time-based parameters correlate well with stroke volume. Monitoring pulse transit time may assist in evaluation for spontaneous PDA closure or response to therapy.
