Infant Nasal Nitric Oxide Levels in Congenital Heart Disease

Status Terminated

Clinical Trial Summary

This pilot study aims to measure nasal nitric oxide (nNO) in a group of neonates and infants (≤ 12 months) with congenital heart disease (CHD) and compare their nNO levels to age matched controls without CHD. CHD patients will be divided into subgroups, based on their cardiac anatomy, to try and identify a level of risk of ciliary dyskinesia within the subgroup of CHD. Each of these sub groups' nNO levels will be compared between groups and against age matched control infants without CHD.

Clinical Trial Description

Methods: Parents or legal guardians will be approached to provide written, informed consent. To allow for at least three sub groups of cardiac anomalies (with 20 patients per group), 60 children, less than one year of age, with CHD will be recruited from the Pediatric Cardiology inpatient ward at Stollery Children's Hospital. Sixty age matched controls, without acute respiratory illness, will be recruited from the General Pediatric inpatient ward. All subjects will be breathing room air at the time of nNO measurement.

Subjects: This is a pilot study to gather data to power future studies. The investigators aim to recruit 60 subjects with CHD and 60 normal controls without CHD. 60 subjects will allow for at least three sub groups of cardiac anomalies with 20 subjects per group.

Control group: The control group will consist of age matched infants, less than one year of age, without CHD or acute respiratory illness. They will also require written informed consent and will have to be breathing room air at the time of the nNO test.

Investigational device: For nNO assessment, an inert nitric oxide (NO) sampling line with a disposable foam olive (DirectMed Inc., Glen Cove, NY) will be placed into one of the subject's nostrils while the contralateral nostril is left open. Air will be then sampled at a constant rate of 0.3 Liters/min from the nose by a chemiluminescent analyzer which provides measurement of the nNO level in parts per billion (ppb). All nNO measurements will be performed with the subjects supine. Measurements will be obtained using a NO analyzer (CLD 88 SP, ECO PHYSICS AG, Duerten, Switzerland) available at Stollery Children's Hospital. The analyzer will be calibrated according to the manufacturer's specifications. Two samples will be taken five minutes apart, to assess for test-retest reproducibility, with results for each patient being averaged over the two samples. The test is not painful and each sample takes less than a minute. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
