About this study

Official title: Efficacy and Safety of Endovenous Sildenafil Early Management in Newborns Pulmonary Hypertension: a Clinical Trial

Sildenafil is currently approved for the management of pulmonary hypertension of the newborn, with the availability of intravenous presentation it has been seen that the severity condition has already established, many times these patients do not have the adequate clinical response and there are no studies to date that evaluate the efficacy and safety of the same when it is started early in these patients, therefore we plan a randomized clinical trial to determine the efficacy and safety of the administration of intravenous sildenafil for early management of newborns with persistent pulmonary hypertension of the newborn.

Read the detailed description

Persistent pulmonary hypertension of the newborn is a relatively common condition that occurs in 2 to 7/1000 live births, being higher in term and late preterm newborns, representing up to 4% of all admissions in some units neonatal intensive care and that results in a mortality that ranges between 4 and 33% in the world. In the United States, its incidence varies between 0.4 and 6.8 per 1000 live births, while in the United Kingdom it is between 0.43 and 6 per 1000 live births. Although there has been an important development in the treatment of persistent pulmonary hypertension of the newborn in the last time, its impact on early neonatal mortality continues to be important, reaching approximately 10%. Currently there are no mortality data in underdeveloped countries and in Latin America. This considerable mortality is most likely a consequence of the fact that 40% of newborns are resistant to inhaled nitric oxide, which, together with supportive therapies, is the basis of treatment. Furthermore, the increasing cost of administering Nitric oxide to infants with pulmonary hypertension of the newborn reduces its availability in developing countries. On the other hand, extracorporeal membrane oxygenation is another therapeutic option that is currently being systematically evaluated in clinical trials, even so, it is not available in all units. Therefore, there was a real need to evaluate novel approaches for the management of the disease, being necessary to create therapeutic strategies that allow improving the prognosis of these newborns. Sildenafil is currently approved for the management of persistent pulmonary hypertension of the newborn, with the availability of intravenous presentation it has been seen that once the severity picture has been established, many times these patients do not have the adequate clinical response and there are no studies to date that evaluate the efficacy and safety of the same when started early in these patients.

Primary outcome: To assess the efficacy in decreasing estimated pulmonary artery pressure by 20% and improving survival with early use of intravenous sildenafil at a loading dose of 0.4 mg / kg in 3 hours, followed of continuous infusion at 1.6 mg / kg / day versus conventional treatment plus placebo in neonates with persistent pulmonary hypertension of the newborn.

Materials and methods:

A total of 44 newborns with a gestational age ≥ 34 weeks of age and less than 10 days old who were admitted to the Neonatal Intensive Care Unit, High Complexity Medicine with a diagnosis of persistent pulmonary hypertension of the newborn in absentia, were evaluated. of congenital heart disease or oxygenation index greater than 15, attended between May 2021 and May 2022 in the city of Barranquilla, 22 were divided into two groups for the control group and 22 for the intervention group. the intervention group received intravenous sildenafil loading dose of 0.4 mg / kg in 3 hours and continued in continuous infusion at 1.6 mg / kg / day (0.067 mg / kg / h). The control group will receive placebo at the same loading dose and infusion with 0.9% saline solution plus standard management under the unit protocol immediately after the echocardiographic diagnosis. The measure of the primary outcome was given by the decrease of 20% in the estimated pressure of the pulmonary artery by echocardiography at 24 hours after the start of treatment, at 48 hours, between 96 - 168 hours and 48 hours after the drug discontinuation.

Results and conclusions: ongoing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 20% decrease in estimated pulmonary artery pressure

    Evaluate the efficacy in lowering the estimated pulmonary artery pressure by 20% and improved survival with early use of intravenous sildenafil at a loading dose of 0.4 mg / kg in 3 hours, followed by continuous infusion at 1.6 mg / kg / day versus conventional treatment plus placebo in neonates with persistent pulmonary hypertension of the newborn.

    Measured: 7 days

Secondary outcomes (3)
  1. Duration of mechanical ventilation

    Evaluate the duration of mechanical ventilation with early use of intravenous sildenafil at a loading dose of 0.4 mg / kg in 3 hours, followed by continuous infusion at 1.6 mg / kg / day versus conventional treatment plus placebo in neonates with persistent pulmonary hypertension of the newborn.

    Measured: 7 days

  2. Duration of inotropic therapy

    To assess the duration of inotropic therapy with early use of intravenous sildenafil at a loading dose of 0.4 mg / kg in 3 hours, followed by continuous infusion at 1.6 mg / kg / day versus conventional treatment. plus placebo in neonates with persistent pulmonary hypertension of the newborn.

    Measured: 7 days

  3. Adverse events

    Correlate the presence of adverse events such as arterial hypotension, the presence of bleeding and retinopathy of prematurity with the early use of intravenous sildenafil at a loading dose of 0.4 mg / kg in 3 hours, followed by continuous infusion at 1.6 mg / kg / day versus conventional treatment plus placebo in neonates with persistent pulmonary hypertension of the newborn.

    Measured: 7 days
