Initiation of Acid Suppression Therapy Prospective Outcomes for Laryngomalacia

Laryngomalacia (LM) is the most common cause of stridor in infants. Symptoms of gastroesophageal reflux (GER) are often seen in the setting of LM; therefore, acid suppression therapy (AST) has been empirically used in the management of this disorder. The investigators recently performed a retrospective chart review assessing improvement of airway and dysphagia symptoms, weight gain, and need for surgery with AST. It was found that there was a similar improvement between LM severity groups and most patients received AST (96.6%). It is unclear if these improvements are due to AST or natural resolution of the disease. With heightened concerns of side effects related to AST in infants, particularly among those born prematurely, judicious use of these medications is needed. The investigators are now performing a prospective study looking at the outcome differences in patients with laryngomalacia who are evaluated by speech language therapy (SLP) alone versus those with SLP evaluation and acid suppression therapy (famotidine).

Study Overview

• Status: Active, not recruiting
• Conditions: Gastro Esophageal Reflux; Laryngomalacia
• Intervention / Treatment: Other: Speech Language Therapy; Drug: Famotidine

Detailed Description

Purpose: To determine the outcome differences in patients 6 months and younger with laryngomalacia and dysphagia who are evaluated by speech language therapy (SLP) alone versus those with both SLP evaluation and acid suppression therapy (AST) (famotidine)

Hypothesis: There will be no differences in outcomes between those that had SLP alone versus those that had both SLP and AST.

Laryngomalacia (LM) is the most common cause of stridor in infants. Symptoms of gastroesophageal reflux (GER) are often seen in the setting of LM; therefore, acid suppression therapy (AST) has been empirically used in the management of this disorder. However, there is no gold standard in treating mild and moderate LM patients and therefore this study will help establish guidelines for treatment.

A medical chart review will be performed to assess airway and dysphagia symptom improvement from consult to the 3-month follow up appointment and then up to a year. The Pittsburgh Airway Symptom Score (PASS) questionnaire and the Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) will be given to families at the consult and at the 3-month follow up appointment for caregiver assessment. The physician will then perform the standard procedures at the clinic appointment. The Flexible Laryngoscopy Findings sheet will be filled out in conjunction with the clinic procedures for objective data. The surveys will then be scored to determine true GERD (score >=16) and severe laryngomalacia (LM) (RED questions on the PASS), which would further exclude these patients. There are 12 total questions on the I-GERQ-R. On the PASS, questions 1 & 2 are in the GREEN category and signifies mild LM, YELLOW signifies moderate LM, and RED is severe LM. On the PASS questionnaire, "Yes" to either #1 or #2 and nothing else is mild LM, "yes" to at least one #3-5 and none of #6-10 is moderate LM, and "yes" to any of the #6-10" indicates severe LM. There are 10 total questions on the PASS. Mild and moderate LM patients will be block randomized the day before the appointment to receive speech language therapy alone or speech language therapy with famotidine (Pepcid). Both treatments are standard of care in these patients. Speech language therapy (feeding therapy) is part of the normal clinic visit for LM patients. These patients will then be re-evaluated at their follow up appointment in 3 months (+/- 1 month). The families will take the PASS and I-GERQ-R surveys again to determine LM severity.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Speech Language Therapy Alone; Patients in this group will receive a routine swallowing evaluation by a speech language pathologist. Patient caregivers will fill out the Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) and the Pittsburgh Airway Symptom Score (PASS) the day of the appointment and at the 3-month follow up appointment.	Other: Speech Language Therapy; Speech Language Therapy (feeding therapy) will be provided by a speech language pathologist to assess feeding and swallowing.
Active Comparator: Speech Language Therapy and Acid Suppression Therapy; Patients in this group will receive a routine swallowing evaluation by a speech language pathologist and famotidine (acid suppression therapy). Patient caregivers will fill out the Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) and the Pittsburgh Airway Symptom Score (PASS) the day of the appointment and at the 3-month follow up appointment.	Other: Speech Language Therapy; Speech Language Therapy (feeding therapy) will be provided by a speech language pathologist to assess feeding and swallowing.; Drug: Famotidine; Famotidine will be prescribed based on patients' weight. Caregivers will purchase this medication and dosage will be given to families in easy-to-understand language.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Airway symptom score change from consult (baseline) to 3 month follow-up appointment	Score change from pre to post surveys on the Pittsburgh Airway Symptom Score (PASS) questionnaire. The PASS is on a scale from 0-10 with a higher score indicating a worse outcome. This outcome will be assessed at the consult and the 3 month follow-up appointment.	3 months
Dysphagia symptom score change from consult (baseline) to 3 month follow-up appointment	Score change from pre to post surveys on the Pittsburgh Airway Symptom Score (PASS) questionnaire. The PASS is on a scale from 0-10 with a higher score indicating a worse outcome. This outcome will be assessed at the consult and the 3 month follow-up appointment.	3 months
Change in incidence of airway symptoms from consult up to 1 year assessed via electronic medical chart review	Change in incidence of airway symptoms from consult up to 1 year assessed via electronic medical chart review. Notes from the Department of Otolaryngology will be reviewed which include reported symptoms from caregivers and symptoms seen upon exam. Airway symptoms included periods of apnea, chest wall retractions, cyanosis, stridor, noisy breathing, and increased respiratory rate.	1 year
Change in incidence of dysphagia symptoms from consult up to 1 year assessed via electronic medical chart	Change in incidence of dysphagia symptoms from consult up to 1 year assessed via electronic medical chart review. Notes from the Department of Otolaryngology will be reviewed which include reported symptoms from caregivers and symptoms seen upon exam.
