Prevalence of Minimal Change Lesions in Patients with Non-Erosive Reflux Disease: A Case-Control Study
Digestion, 05/15/2012Kim JB et al.
Minimal changes (MCs) could be a useful marker to support clinical diagnosis of gastroesophageal reflux (GERD). White mucosal turbidity in particular might be a GERD–specific sign related to acid–induced mucosal damage.
Twelve endoscopic findings in the esophagogastric junction were prospectively compared between NERD (n = 64) and control (n = 104).
Overall frequency of MC (≥1 out of 12 criteria) was higher in the NERD group (71.9%) than in the HC group (45.2%).
In individual analysis, white mucosal turbidity, irregular Z-line, horizontal erosions, and mucosal protrusion of cardia were significantly more common in the NERD group compared to controls.
Among them, only white mucosal turbidity was independently associated with the NERD group (OR 3.97, 95% CI 1.72-9.13).
Individuals with male gender, reflux symptoms, higher height, current smoking, ethanol intake and hiatal hernia were more likely to have white mucosal turbidity compared to the group without white turbidity.
