Ibuprofen vs. Continuous Indomethacin in the Treatment of PDA
Summary
The purpose of this study is to determine whether closure of the PDA in premature neonates using IV ibuprofen vs continuous IV indomethacin has different side effects, eg. effects on renal function, on blood flow velocity in the superior mesenteric artery, the anterior cerebral artery, and the renal artery.
Description
Despite the fact that ibuprofen appears to minimize the renal side effects seen following bolus indomethacin, other concerns regarding both short and long-term safety remain. Indomethacin, on the other hand, has been used to treat premature neonates for many years. Other than transient vasoconstrictive effects, no significant toxicity has been noted. Thus, if we were to be able to eliminate the differential renal effects, indomethacin would remain, for many, the therapy of choice for the premature neonate with a persistent PDA. We hypothesized that continuous administration of indomethacin would provide this option. Ibuprofen therapy has not, to date, been compared with indomethacin administered by continuous infusion. Hence, in the current study we attempted to determine whether continuous indomethacin administration could potentially offer the same advantages as ibuprofen in treating PDA, specifically in terms of mitigation of renal side effects. Specifically, our primary objective was to show no differences in urine output and/or in serum creatinine between the treatment groups. As a secondary objective, we aimed to show no other potentially vascular-mediated clinical differences, eg. Necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), retinopathy of prematurity (ROP) and on bilirubin albumin binding between the groups.
B-type natriuretic peptide (BNP) is released by ventricular myocytes in response to ventricular volume load. It, in turn, mediates vasodilation, natriuresis and diuresis. Serum BNP levels have been shown to be clinically useful in differentiating between respiratory and cardiac disease, in monitoring heart failure therapies and in serving as early diagnostic biomarkers of ductal patency in premature neonates. As secondary objectives we intend to determine whether a decrease in BNP levels would be an equally reliable indicator of therapeutic efficacy in infants treated with ibuprofen as with indomethacin.In addition we will look at comparative effects on other vascular beds which might mediate long term side effects described above.

Medical and Biotech [MESH] Definitions
Ductus Arteriosus, Patent
A congenital heart defect characterized by the persistent opening of fetal DUCTUS ARTERIOSUS that connects the PULMONARY ARTERY to the descending aorta (AORTA, DESCENDING) allowing unoxygenated blood to bypass the lung and flow to the PLACENTA. Normally, the ductus is closed shortly after birth.
Persistent Fetal Circulation Syndrome
A syndrome of persistent PULMONARY HYPERTENSION in the newborn infant (INFANT, NEWBORN) without demonstrable HEART DISEASES. This neonatal condition can be caused by severe pulmonary vasoconstriction (reactive type), hypertrophy of pulmonary arterial muscle (hypertrophic type), or abnormally developed pulmonary arterioles (hypoplastic type). The newborn patient exhibits CYANOSIS and ACIDOSIS due to the persistence of fetal circulatory pattern of right-to-left shunting of blood through a patent ductus arteriosus (DUCTUS ARTERIOSUS, PATENT) and at times a patent foramen ovale (FORAMEN OVALE, PATENT).
Ductus Arteriosus
A fetal blood vessel connecting the pulmonary artery with the descending aorta.
Hypoplastic Left Heart Syndrome
A condition caused by underdevelopment of the whole left half of the heart. It is characterized by hypoplasia of the left cardiac chambers (HEART ATRIUM; HEART VENTRICLE), the AORTA, the AORTIC VALVE, and the MITRAL VALVE. Severe symptoms appear in early infancy when DUCTUS ARTERIOSUS closes.
Truncus Arteriosus, Persistent
A congenital anomaly caused by the failed development of TRUNCUS ARTERIOSUS into separate AORTA and PULMONARY ARTERY. It is characterized by a single arterial trunk that forms the outlet for both HEART VENTRICLES and gives rise to the systemic, pulmonary, and coronary arteries. It is always accompanied by a ventricular septal defect.
