“…Fifty-six preterm newborns at 48-72 h of life with echocardiograph evidence of a hemodynamically significant PDA were treated intravenously with IBU according to literature data [15]. The protocol provided a course of three doses of IBU (an initial dose of 10 mg/kg, followed by two 5 mg/kg doses after 24 and 48 h).…”
Patent ductus arteriosus (PDA) is the most common cardiovascular abnormality of the preterm infant usually treated with ibuprofen (IBU). PDA is strictly related to oxidative stress (OS) in neonates. This study tests the hypothesis that OS occurs in neonates with PDA and that IBU treatment reduces OS. Forty-three preterm babies with gestational age (GA) <33 weeks were studied prospectively. Three urine samples were collected: at time 0 (before starting treatment), time 1 (after pharmacological PDA closure), and time 2 (7 days after the end of treatment) in all patients. OS was studied by measuring urinary isoprostane (IPs) levels. The results showed significant changes in urinary IP levels from time 0 to time 2 (Kruskal-Wallis, p=0.047). Time trend showed a significant decrease in IPs from time 0 to time 1 after IBU therapy (p=0.0067). This decrease was followed by an increase in IPs levels 7 days after treatment. IBU therapy for PDA closure reduced the risk of OS related to free-radical (FR) generation. This antioxidant effect of IBU may be beneficial in preterm babies with PDA who are at high risk for OS.

“…Van Overmeire et al demonstrated significantly lower creatinine values (and greater urine output) in the ibuprofen group compared to indomethacin, when administered to preterm infants (24 to 32 weeks of gestation) [35]. Additionally, a recent Cochrane analysis [21] noted that ibuprofen was associated with a reduced risk of oliguria and lower serum creatinine levels following treatment.…”
Indomethacin was more efficacious for ductal closure although did not impact outcomes. Use of staging schema may help understand 'need to treat' and refine therapy.
“…The current recommended indication for non-steroidal anti-inflammatory drugs (NSAIDs) in the preterm neonatal period is the curative medical treatment of persistent ductus arteriosus [20]. Experimental data indicate that NSAIDs could be neuroprotective in the developing brain in the context of systemic inflammation, through a reduction in brain prostaglandin E 2 synthesis by cyclooxygenase-2 inhibition at the blood-brain barrier [21].…”

Background: Over the last decades, considerable progress has been made in the perinatal management of high-risk preterm neonates, changing the landscape of pathological conditions associated with neurological impairments. Major focal destructive lesions are now less common, and the predominant neuropathological lesion is diffuse white-matter damage in the most immature infants. Similarly, over the last few years, we have observed a trend towards a decrease in neurological impairment in the absence of treatments specifically aimed at neuroprotection. Objectives: We examined whether recent changes in treatment strategies in perinatal care during the perinatal period could have had an indirect beneficial impact on the occurrence of brain lesions and their consequences. Methods: Thus, we reviewed the effects of the most common treatments administered during the perinatal period to the mother or to very preterm infants on brain damage and neurocognitive follow-up. Results: Antenatal steroids and exogenous surfactant are the two main treatments capable of leading to neuroprotection in very preterm infants. Randomized controlled trials are currently investigating the effects of inhaled nitric oxide and erythropoietin, while antenatal magnesium sulphate and caffeine are also likely to provide some neuroprotection, but this needs to be further investigated. Finally, other common treatments against pain, haemodynamic failure and patent ductus arteriosus have conflicting or no effects on the developing brain. Conclusion: While specific neuroprotective drugs are still awaited, recent advances in perinatal care have been associated with an unexpected but significant decrease in the incidence of both severe brain lesions and neurological impairment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
