Children with severe heart failure need immediate appropriate care. New and better drugs are constantly being developed. As these drugs are approved for adult use, they are used off-label for children. The Food and Drug Administration (FDA) encourages clinical studies of drugs in children to further extend appropriate use of new medicines.

This study involves nesiritide, which was approved as a congestive heart failure treatment in adults in August 2001. The investigators' use of this drug in a pediatric population with severe heart failure has been encouraging. The investigators now wish to formally determine the pharmacokinetic and safety of Nesiritide in children.

The investigators will enroll 30 patients who are in the cardiac intensive care unit with severe heart failure. The data collected will include weights, vital signs, laboratory results, and echocardiography results. A research lab test called B-type natriuretic peptide (BNP) will be done several times during this study. If the patient still has an intravenous (IV) catheter, the blood sample will be taken from the IV. If the patient does not have an IV, the sample will be taken from a fingerstick.

The duration of the study will be the first 2 days of the patient's stay in the cardiac intensive care unit and thru discharge to evaluate the endpoint safety of Nesiritide. Additional information will also be collected if patient gets re-admitted within 30 days of discharge.

Arms Assigned Interventions
Experimental: Nesiritide Drug: Nesiritide
Standard dose of nesiritide which is a loading dose of 1 mcg/kg IV over 30 minutes followed by a nesiritide infusion at 0.01mcg/kg/min. All patients will be continually evaluated. At any time the attending physician may add or adjust treatment if deemed clinically indicated.

Detailed Description:

Nesiritide (human recombinant B-type natriuretic peptide) has been recently approved by the Food and Drug Administration for the intravenous treatment of patients with decompensated congestive heart failure. Nesiritide has been studied in a broad range of patients, including the elderly, women, and African Americans, and patients with a history of various cardiovascular conditions including hypertension, diabetes, post myocardial infarction, atrial fibrillation/flutter, nonsustained ventricular tachycardia, left ventricular diastolic dysfunction, and acute coronary syndrome. However, clinical experience in the pediatric population has been limited.

Nesiritide is a human B-type natriuretic peptide (BNP) produced by recombinant technology having the same amino acid sequence as the naturally occurring human BNP. BNP is predominantly secreted by the cardiac ventricles in response to increased cardiac volume and pressure overload. Its pharmacologic effects include hemodynamic, neurohormonal, and renal. In adult studies, hemodynamic effects are characterized by balanced venous and arterial dilation, resulting in decreased preload and afterload demonstrated by a reduction of pulmonary capillary wedge pressure, pulmonary arterial pressure, and systemic vascular resistance while neurohormonal effects of nesiritide favorably inhibit the renin-angiotension-aldosterone system, leading to decreased plasma aldosterone and norepinephrine levels. The renal effects most often seen with nesiritide use is increased urine output and lower diuretic utilization.

There are currently no published articles discussing the use, including pharmacokinetics, of nesiritide in children. However, there are several centers that are currently using the drug - Columbus, Missouri; San Diego, California; Charleston, South Carolina; Loma Linda, California. Our experience in the infant after cardiac surgery and the older child with heart failure is encouraging. In children receiving nesiritide therapy, we noted significant clinical improvement with no appreciable side effects. Based on our initial experience, further prospective studies need to be performed in order to determine the pharmacokinetics and safety of using this therapy in the pediatric cohort.
