Oral Ibuprofen and the patent ductus arteriosus: a new approach to an old problem.

چکیده
Patent ductus arteriosus (PDA) is present in up to 75% of infants born before 28 weeks gestation, and issues concerning PDA remain a popular topic in neonatology. The large range of articles addressing the assessment and treatment of PDA demonstrates the continuing uncertainty regarding the best way to manage an infant with this complication of prematurity. PDA is associated with many of the adverse outcomes of prematurity; however, there are conflicting results on the benefits of PDA closure from the many randomised and observational studies targeting PDA treatment. Consequently, there are ongoing questions as to when to treat, what to treat, and how to treat. Complicating factors, such as efficacy, dosage issues, risk of side effects, and the large variation in cost of potential treatments are becoming increasingly important, as neonatologists try to optimize available therapies. Neonatology has a track record of introducing medications before the pharmacokinetics in our population are properly understood. Enteral or intravenous indomethacin was the mainstay of PDA treatment for many years, ever since its use was first described in 1976. More recently, ibuprofen, initially as an intravenous infusion, has been utilized and found to be of similar efficacy as intravenous indomethacin. There are, however, indications that the appropriate dose to maintain therapeutic ibuprofen levels is not being achieved with intravenous dosing, resulting in increased treatment failure rates. Oral medication, which is simple to administer and effective, with minimal side effects, would be likely to change the balance in favour of treatment in many preterm infants. In this issue of the Journal, Yang et al. describe their experience with the use of oral ibuprofen versus intravenous indomethacin in a group of extremely low birth weight infants. In this retrospective cohort study, oral ibuprofen syrup (10 mg/kg initial dose, followed by two doses of 5 mg/kg at 24-hour intervals) was found to be as efficacious as intravenous indomethacin. The closure rate on initial treatment was 81.8% for oral ibuprofen versus 88.5% for intravenous indomethacin (p = 0.40). Importantly, there were no differences in side effects or complications between the two approaches. These were small infants, all under 1,000 g, and treated on average at 5 days of age. Other studies have confirmed the high closure rates and favourable safety profile of oral ibuprofen. Most recently, Erdeve et al. performed a randomised controlled trial of oral versus intravenous ibuprofen in 80 preterm infants, and found a higher initial closure rate with oral ibuprofen, though there was a higher re-opening rate in infants who received this treatment. Interestingly, there was also a reduction in the incidence of chronic lung disease in the orally treated group. Other studies have

Background The function of ductus arteriosus closes within a few minutes to a few days after birth in term neonates. In some cases, the duct remains open after birth, a condition which is called patent ductus arteriosus (PDA). PDA is associated with high rates of neonatal mortality and morbidity. The present study aims to evaluate the effect of...

Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...

Patent ductus arteriosus (PDA) is a persistent patency of a vessel normally present in the fetus that connects the pulmonary arterial system to the aorta. The ductus arteriosus fails to close at birth when breathing commences and placental blood circulation is removed. Closure of the ductus arteriosus arises in response to decline pulmonary vascular resistance and increased systemic vascular re...
متن کاملDoes ibuprofen treatment in patent ductus arteriosus alter oxygen free radicals in premature infants?
Introduction Ibuprofen is used widely to close patent ductus arteriosus in preterm infants. The anti-inflammatory activity of ibuprofen may also be partly due to its ability to scavenge reactive oxygen species and reactive nitrogen species. We evaluated the interaction between oxidative status and the medical treatment of patent ductus arteriosus with two forms of ibuprofen. Materials and metho...
