Abstract
Objective
To assess the impact of diet on the occurrence of proximal reflux episodes at the multichannel intraluminal impedance-pH monitoring (MII-pH) in patients with laryngopharyngeal reflux (LPR).
Methods
Patients with LPR symptoms and findings were recruited from three European hospitals. The LPR diagnostic was confirmed through MII-pH and patients were benefited from gastrointestinal (GI) endoscopy. Regarding the types of reflux at the MII-pH (acid, nonacid, mixed), patients received a 3 month-therapy based on the association of alkaline, low-fat and high-protein diet, proton pump inhibitors, alginate or magaldrate. Reflux symptom score (RSS) and reflux sign assessment (RSA) were used to evaluate laryngeal and extra-laryngeal symptoms and findings from pretreatment to posttreatment. The Global Refluxogenic Score (GRES) was used to assess the refluxogenic potential of the diet of the patients at baseline and posttreatment. The relationship between GRES severity; the MII-pH findings; GI endoscopy; and the therapeutic response was explored through multiple linear regression.
Results
Eighty-five LPR patients were included. The mean GRES significantly improved from pretreatment (50.7 ± 23.8) to posttreatment (27.3 ± 23.2; P = 0.001). Similarly, RSS and RSA significantly improved from baseline to posttreatment. The baseline GRES was significantly associated with the occurrence of proximal reflux episodes at the MII-pH (P = 0.001). Trends were found regarding the association between GRES and the occurrence of esophagitis (P = 0.06) and between hiatal hernia and DeMeester score (P = 0.06). There was a significant and strong association between the concomitant respect of diet and medication and the improvement of RSS (P = 0.001).
Conclusion
The consumption of high-fat, low-protein, high-sugar, acid foods, and beverages is associated with a higher number of proximal reflux episodes at the MII-pH, according to the global refluxogenic score of LPR patients.
