Brief Summary

Noisy breathing is commonly caused by a floppy voicebox which is a condition called laryngomalacia. The cause of laryngomalacia is not fully understood, but some studies have suggested that it could be due to acid escaping from the stomach and spreading up the swallowing passage to the throat (acid reflux). This affects about 1 in 100 newborns and is therefore one of the most common reasons for infants to see Otolaryngologists at BC Children's Hospital (BCCH). These infants can have a spectrum of distressing symptoms including squeaky breathing, choking, difficulty feeding, failure to gain weight, and episodes of turning blue (due to lack of oxygen). At present, Otolaryngologists at BCCH will sometimes give children with laryngomalacia medication to reduce the amount of acid they make in their stomachs, in the hope that this will reduce their symptoms of laryngomalacia. It has never been scientifically confirmed whether anti-reflux medication will benefit these children any more than doing nothing at all.

Outcome Measures

Primary Outcomes (1)

• Laryngomalacia Symptom Score

  This score is a disease-specific quality of life measure for laryngomalacia. Each of the symptoms that can occur in laryngomalacia are scored as present (1) or absent (0) as follows - inspiratory stridor, suprasternal retraction, substernal retraction, feeding difficulty, choking, post-feeding vomit, failure to thrive (i.e. poor weight gain with deviation from the normal growth curve), and cyanosis. Therefore for each patient, a total symptom score is calculated (8 = all symptoms, 0 = no symptoms).

  Change from baseline and at end of study (baseline and 8 weeks)

Secondary Outcomes (5)

• Caring For a Child with Laryngomalacia Family Impact Questionnaire

  Change from baseline and at end of study (baseline and 8 weeks)

• Revised Infant Gastro-Esophageal Reflux Questionnaire

  Change from baseline and at end of study (baseline and 8 weeks)

• Reflux Finding Score

  Change from baseline and at end of study (baseline and 8 weeks)

• End of treatment 24-hour double-probe pH monitoring

  Change from baseline and at end of study (baseline and 8 weeks)

• Weight

  Change from baseline, to half-way point and at end of study (baseline, 4 weeks and 8 weeks)

Study Arms (2)

Placebo

PLACEBO COMPARATOR

Two different placebo formulations will be created which will designed to be identical in appearance, taste, and consistency to the two study medications.

Drug: Placebo

Omeprazole

ACTIVE COMPARATOR

Omeprazole (a proton-pump inhibitor) is the most common treatment given to infants with laryngomalacia, in the hope that this will reduce their symptoms. Although this is an effective anti-reflux medication in this population, its use is off-label, and like any medication has potential risks, particularly in very young children. 2 mg/kg/day omeprazole.

Drug: Omeprazole

Interventions

Omeprazole DRUG

Omeprazole (a proton-pump inhibitor) is the most common treatment given to infants with laryngomalacia, in the hope that this will reduce their symptoms. Although this is an effective anti-reflux medication in this population, its use is off-label, and like any medication has potential risks, particularly in very young children. Side effects that have been described include abdominal pain, diarrhea, constipation, and cough. Although omeprazole is usually a safe medication, we do not currently know if it provides any benefit in laryngomalacia.
