Different clinical symptom patterns in patients with reflux micro-aspiration

Abstract

BackgroundPulmonary manifestation of gastro-oesophageal reflux disease (GORD) is a well-recognised entity, however little primary reported data exists on presenting symptoms of patients in whom reflux micro-aspiration is confirmed. The aim of this study is to report symptoms and presenting patterns of a large group of patients with confirmed reflux micro-aspiration.Patients and methodsData was extracted from a prospectively populated database of patients referred to a tertiary specialist centre with severe, refractory, or atypical reflux. Patients with reflux micro-aspiration on scintigraphy were included in this study. Separate group included patients with evidence of proximal reflux to the level of pharynx when supine and/or upright.ResultsInclusion criteria were met by 243 patients with confirmed reflux micro-aspiration (33% males; mean age 59). Most common symptoms amongst patients with micro-aspiration were regurgitation (72%), cough (67%), heartburn (66%), throat clearing (65%), and dysphonia (53%). The most common two-symptom combinations were heartburn/regurgitation, cough/throat clearing, regurgitation/throat clearing, cough/regurgitation and dysphonia/throat clearing. The most common three-symptom combinations were cough/heartburn/regurgitation, cough/regurgitation/throat clearing and dysphonia/regurgitation/throat clearing. Cluster analysis demonstrated two main symptom groupings, one suggestive of proximal volume reflux symptoms and the other with motility/inflammatory bowel syndrome (IBS)-like symptoms (bloat, constipation).ConclusionCombination of typical symptoms of GORD such as heartburn or regurgitation and a respiratory or upper aero-digestive complaint such as cough, throat clearing, or voice change should prompt consideration of reflux micro-aspiration.

Is There a Potential Link between Gastroesophageal Reflux Disease and Recurrent Respiratory Tract Infections in Children?

“…There were also patients that associated three symptoms; heartburn with regurgitation and throat clearing being present in most cases, followed by cough, regurgitation and throat clearing. These findings suggest that cough that appears in a patient with regurgitation or heartburn should guide us to investigate a possible reflux with subsequent micro-aspiration in order to prevent pulmonary damage and further bacterial infection [ 26 ].…”
