In females, salivary secretion was significantly lower in patients with severe reflux esophagitis than in healthy controls.
Background: The salivary secretion in patients with mild reflux esophagitis (RE) and non-erosive reflux disease is significantly lower in females, but not in males. However, sex differences in salivary secretion in patients with severe RE remain unknown. Therefore, the present study investigated sex differences in saliva secretion in patients with severe RE.
Methods: Subjects consisted of 23 male patients with severe RE, 24 male healthy controls (HCs), 26 female patients with severe RE, and 25 female HCs. Saliva secretion was assessed as follows: each patient chewed sugarless gum for 3 min prior to endoscopy, and the amount and pH of saliva secreted before and after acid loading as an index of the acid-buffering capacity were measured.
Results: In males, no significant differences were observed in the amount of saliva secretion, salivary pH, or the acid-buffering capacity between severe RE patients and HCs. In females, the amount of saliva secretion (severe RE: 2.4 [1.8-4.1], HCs: 5.3 [3.4-7.5], p = 0.0017), salivary pH (severe RE: 7.0 [6.7-7.3], HCs: 7.2 [7.1-7.3], p = 0.0455), and the acid-buffering capacity (severe RE: 5.9 [5.3-6.2], HCs: 6.2 [6.1-6.5], p = 0.0024) were significantly lower in severe RE patients than in HCs.
Conclusion: Among females, the salivary secretion was significantly lower in severe RE patients than in HCs. This reduction in salivary secretion may contribute to the pathophysiology of severe RE in females.
期刊介绍：
Esophagus, the official journal of the Japan Esophageal Society, introduces practitioners and researchers to significant studies in the fields of benign and malignant diseases of the esophagus. The journal welcomes original articles, review articles, and short articles including technical notes ( How I do it ), which will be peer-reviewed by the editorial board. Letters to the editor are also welcome. Special articles on esophageal diseases will be provided by the editorial board, and proceedings of symposia and workshops will be included in special issues for the Annual Congress of the Society.
