Role of esophageal symptoms in the diagnosis of gastroesophageal reflux disease in children with recurrent and chronic respiratory diseases

Abstract

Introduction: Gastroesophageal reflux disease (GERD) is one of comorbid diseases, that worsen the course and outcomes of respiratory pathology. The study aimed to determine role of esophageal symptoms in the diagnosis of GERD in children with recurrent and chronic respiratory diseases (RCRD).

Methods: The study included 125 children (70 boys, 55 girls), median 3,75 years (interquartile range, IQR – 1,21-9,38 years), with RCRD, refractory to standard therapy. GERD was diagnosed on the basis of clinical and complex instrumental examination, including fluoroscopy esophagus with contrast, esophagogastroduodenoscopy (EGDS), 24-hour esophageal pH-monitoring, dual pH-multichannel intraluminal impedance (pH-MII).

Results: In children with RCRD, the frequency of GERD was 86,4%. Among children without esophageal manifestations of GERD, pathological reflux was confirmed by instrumental methods in 81% of patients; in children with esophageal manifestations - 92%, with no statistically significant differences (p = 0,0637). Nonacid reflux is more common in patients without esophageal manifestations of GERD.

Conclusions: The frequency of GERD in children with RCRD is very high. It is possible to screen GERD in children with RCRD, independent on the presence of clinical esophageal symptoms.
