Abstract
INTRODUCTION The optimal management of a patent ductus arteriosus in a population of preterm infants is controversial. Traditionally, when the patent ductus arteriosus does not close either with conservative treatment or in response to pharmacological therapy, the only option is surgical closure. However, transcatheter occlusion might provide a therapeutic alternative. METHODS We searched PubMed, Embase, and Cochrane databases for non-randomised and randomised controlled trials that compared transcatheter percutaneous closure of patent ductus arteriosus with surgical ligation in low-birth-weight preterm infants (<2,500 g). A random-effects model was used for outcomes with high heterogeneity. RESULTS We included twelve studies comprising 4,668 low-birth-weight preterm infants, of whom 966 (20.7%) were in the transcatheter percutaneous closure group, and 3,702 (79.3%) patients were included in the surgical group. All-cause mortality (OR 0.28; 95% confidence interval 0.18-0.423; p < 0.00001; I2 = 0%) and haemodynamic instability (OR 0.10; 95% confidence interval 0.05-0.21; p < 0.001; I2 = 14%) were significantly lower in the transcatheter percutaneous closure group. There was no significant difference between transcatheter and surgical patent ductus arteriosus closure for the outcomes of bronchopulmonary dysplasia (0.93; 95% confidence interval 0.46-1.87; p = 0.83; I2 = 0%) and major complications (OR 0.76; 95% confidence interval 0.34-1.69; p = 0.51; I2 = 43%). CONCLUSION These findings suggest that transcatheter patent ductus arteriosus closure in preterm infants under 2,500 g is a safe and effective alternative to surgical treatment. There was a substantial reduction in all-cause mortality and haemodynamic instability with transcatheter intervention compared to surgical closure.

Abstract
OBJECTIVE This study aimed to determine the association between daily fluid intake and the duration of hemodynamically significant patent ductus arteriosus (hsPDA). STUDY DESIGN This is a retrospective cohort study of extremely preterm infants (<29 weeks) admitted in the Neonatal Intensive Care Unit of the Advent Health for Children from January 2013 to March 2016, if hsPDA was diagnosed in first week of life and serial echocardiograms were available. Diagnosis of hsPDA was based on a scoring system and its duration was estimated from serial echocardiograms. Cohort was divided into two groups based on duration of hsPDA (<1week, group A and ≥1 week, group B). Daily fluid intake was categorized as prescribed and actual. Prescribed volume was ordered by clinicians based on birth weight, not including trophic feeds, intravenous (IV) boluses or transfusions, etc. Actual intake was calculated by the electronic medical records based on daily weights and included all enteral or parenteral fluids. Multivariate analysis was performed to determine an association between total daily fluid intake over the first week of life and the duration of hsPDA. Two groups were compared to observe the difference between prescribed and actual daily fluid intakes. RESULTS We enrolled 50 infants in group A and 76 in group B. Infants in group B were of significantly lower gestation and required prolonged ventilation and hospitalization. An association between higher fluid intake in the first 2 days of life and prolonged duration of hsPDA was confirmed by multivariate analysis. Actual fluid intake was significantly higher than prescribed total fluid intake in first 4 days of life for infants in both groups. CONCLUSION In extremely preterm infants, higher fluid intake in first 2 days of life is associated with prolonged duration of hsPDA. Actual daily fluid intake can be significantly higher than prescribed daily fluids due to daily weight changes and additional fluid administration. KEY POINTS · In preterm infants, actual daily fluid intake may be higher than prescribed volume.. · Higher daily fluid intake in first week of life is associated with prolonged duration of PDA.. · PDA scoring system can be helpful for objective assessment of PDA in preterm infants..

Patent ductus arteriosus and spontaneous intestinal perforation in a cohort of preterm infants. J Perinatol 2022; 42:1649-1653. [PMID: 35589970 DOI: 10.1038/s41372-022-01403-8] [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: 10/04/2021] [Revised: 04/04/2022] [Accepted: 04/11/2022] [Indexed: 01/19/2023]
Abstract
OBJECTIVE To assess whether either duration and magnitude of ductal shunt or medical treatment for patent ductus arteriosus (PDA) are related to spontaneous intestinal perforation (SIP). STUDY DESIGN Clinical charts of infants <29 weeks' gestation born from 2006 to 2018 were reviewed. Echocardiographic examinations were evaluated according to McNamara and Sehgal's staging system. RESULTS A higher percentage of patients with SIP had a hemodynamically significant PDA (HSPDA) and was treated with either NSAIDs or paracetamol (79% vs 53% and 81% vs 54%, respectively). Among non-treated patients, we found a 1.32 increase in the odds of SIP per day of persistence of HSPDA. In the cohort of patients treated despite the absence of HSPDA, we found a 2.35 increase in the odds of SIP per dose of drug administered. CONCLUSION Both treating a non-HSPDA and leaving a HSPDA to its natural history seem to be associated with SIP.

Abstract
This study aimed to provide additional information on the influence of perinatal factors on fecal (f)-calprotectin values in preterm infants. Calprotectin was determined from the first spontaneous stool (analyzed on the Alegria device by using the enzyme-linked immunosorbent assay [ELISA] method) obtained from neonates at a mean age of 3.41 ± 2.44 days of life. We analyzed 114 subjects who had a body weight of 1847.67 ± 418.6 g and were born at a gestational age of 32.6 ± 2.43 weeks, without intestinal and other congenital anomalies or any diseases other than those related to premature birth. The values of f-calprotectin are in a positive correlation with female subjects, intrauterine growth restriction, significant ductus arteriosus, enteral feeding intolerance, postnatal prolonged use of broad-spectrum antibiotics, and values of bicarbonates (analyzed in a sample of capillary arterial blood). Measurement of f-calprotectin in the first 7 days after birth can help to early detect the intestinal distress or early staging of necrotizing enterocolitis in premature infants.

Abstract
A persistent patent ductus arteriosus (PDA) can have significant clinical consequences in preterm infants, depending on the degree of left-to-right shunting, its impact on cardiac performance, and associated perinatal risk factors that can mitigate or exacerbate the shunt. Although the best management strategy remains contentious, PDAs that have contraindications to, or have failed medical management have historically undergone surgical ligation. Recently smaller occluder devices and delivery systems have allowed for minimally invasive closure in the catheterization laboratory even in extremely premature infants. The present review summarizes the pathophysiologic manifestations, treatment options and management of hemodynamically significant PDA in preterm infants. Additionally, we review the available literature surrounding the respiratory support and outcomes of preterm infants following definitive PDA closure.

Abstract
BACKGROUND There remains controversy regarding the outcomes resulting from treatment versus conservative management of patent ductus arteriosus (PDA) among preterm infants. The effects of extreme prematurity, hemodynamic status of the PDA, and age at treatment remain poorly defined. STUDY DESIGN This retrospective case-control study including infants < 1250 gm who were categorized into 3 groups: Group 1: without PDA, Group 2: with untreated PDA, and Group 3: treated PDA. Diagnosis and treatment of PDA extracted from the medical records. Demographics, clinical characteristics, and outcomes compared using chi-square and analysis of variance. Logistic regression used to estimate adjusted odds ratios. RESULTS The study included 734 infants, with 141(19%) in Group 1, 329 (45%) in 2, and 264 (36%) in 3. Group 3 had higher incidence of bronchopulmonary dysplasia (BPD) (aOR, 2.9; 95%CI 1.7-4.8). Infant treated for hemodynamically significant PDA (HSPDA) had higher incidence of BPD (aOR, 1.9; 95%CI 1.0-3.8) and retinopathy of prematurity (ROP) (aOR, 3.4; 95%CI 1.6-6.9). There were no differences in outcome associated with treatment among≤26 weeks gestation and the age when treated. CONCLUSION Infants with PDA who were treated had higher incidence of BPD. Among those who were treated, those with HSPDA had a higher incidence of BPD and ROP.

Abstract
Hemodynamically significant patent ductus arteriosus (hsPDA) in premature newborns is associated with a risk of PDA-related morbidities. Classification into risk groups may have a clinical utility in cases of suspected hsPDA to decrease the need for echocardiograms and unnecessary treatment. This prospective observational study included 99 premature newborns with extremely low body weight, who had an echocardiogram performed within the first three days of life. Discriminant analysis was utilized to find the best combination of prognostic factors for evaluation of hsPDA. We used binary logistic regression analysis to predict the relationship between parameters and hsPDA. The cohort's mean and standard deviation gestational age was 27.6 ± 2.55 weeks, the mean birth weight was 1015 ± 274 g. Forty-six (46.4%) infants had a PDA with a mean diameter of 2.78 mm. Median NT-pro-BNP levels were 17,600 pg/mL for infants with a PDA and 2773 pg/mL in the non-hsPDA group. The combination of prognostic factors of hsPDA in newborns of extremely low body weight on the third day of life was determined: NT-pro-BNP, Apgar score, Silverman-Anderson score (Se = 82%, Sp = 88%). A cut-off value of NT-pro-BNP of more than 8500 pg/mL can predict hsPDA (Se = 84%, Sp = 86%).

Abstract
Objectives It has been shown that blood concentrations of NT-proBNP may be useful in identifying preterm infants at risk of hemodynamically significant patent ductus arteriosus and its complications. The aim of the study was to assess predictive value of serum NT-proBNP levels for early ductus arteriosus (DA) closure in very preterm newborns. Methods Fifty-two infants <32 weeks’ gestation aged <72 hours with patent ductus arteriosus (PDA) diameter >1.5 mm were involved in a randomized study. Twenty-seven (52%) of them were treated with ibuprofen or paracetamol starting within the first 3 days of life. Expectant management was applied to 25 (48%) infants. All patients underwent planned echocardiographic (daily) and two serum NT-proBNP measurements within the first 10 days after birth. Depending on the DA closure within the first 10 days of life, 2 groups of patients were formed retrospectively, with closed (n = 30) or patent (n = 22) DA by this age. Results In the first 10 days of life, DA closure occurred in 19 (70%) treated infants and in 11 (44%) infants managed expectantly (p > 0,05). Initial concentrations of NT-proBNP were significantly higher in infants that had patent ductus arteriosus (PDA) at 10 days of life. By the eighth day, median NT-proBNP values in both groups significantly decreased but remained considerably higher in newborns with PDA. NT-proBNP serum concentrations on the second day of life could reliably predict DA closure within the first 10 days after birth in treated babies (the AUC was significant 0.81 [95% CI: 0.58–1.03], p < 0.05) but not in infants who were managed expectantly. Conclusions Serum NT-proBNP concentrations on the second day of life could reliably predict early PDA closure in treated but not in expectantly managed very preterm infants.
