Is this trial a fit for you?

Likely a good fit

Term neonates (gestational age ≥ 37 weeks) with signs of pulmonary hypertension and mean pulmonary artery pressure >25 mmHg, without major congenital cardiac anomalies or bleeding risk.

Probably not a fit

Neonates with duct-dependent systemic circulation, methemoglobinemia, or on other pulmonary vasodilators may not benefit and could be excluded.

What this trial studies

This interventional study compares two groups of term neonates with pulmonary hypertension: one receiving inhaled nitric oxide plus melatonin and the other receiving inhaled nitric oxide alone. Melatonin is given via nasogastric tube at 3 mg/kg every 8 hours during iNO therapy. The trial monitors oxygenation and cerebral perfusion, with iNO dosing adjusted by clinical response, and rescue milrinone allowed if needed. Primary goals include safety and potential improvement in oxygenation and stability; responders may be weaned from iNO as clinically indicated. The study is conducted at Ain Shams University and aims to see if melatonin provides added benefit when used with iNO in this population.

Why it matters

Potential benefit: If successful, melatonin could enhance response to inhaled nitric oxide and improve oxygenation and stability in term neonates with pulmonary hypertension.

How similar studies have gone: Prior work with melatonin or nitric oxide for neonatal pulmonary hypertension has been limited; this study tests a novel combination and its added benefit remains to be established.
