title: Predictive factors of the long-term outcome in reflux esophagitis in a low-prevalence gastroesophageal reflux disease region.
abstract: BACKGROUND
  There are no data concerning the long-term outcome of patients with reflux esophagitis in Taiwan. In this study the outcome and the specific prognostic indicators associated with outcome in patients were assessed retrospectively, 7 years after diagnosis of esophagitis.
  
  
  METHODS
  The study comprised a total of 128 patients with endoscopic esophagitis, diagnosed between January and June 1995, at Taichung Veterans' General Hospital. The outcome at 7 years after diagnosis was assessed by outpatient or telephone interview. Factors associated with requiring long-term acid suppression therapy were analyzed.
  
  
  RESULTS
  In all, 105 patients were eligible for analysis: 61 patients (58.1%) with LA (Los Angeles classification) grade A, 29 patients (27.6%) with grade B, 11 patients (10.5%) with grade C and 4 patients (3.5%) with grade D esophagitis. Seven years after diagnosis, there were 52 patients (49.5%) with no or occasional reflux symptoms, 8 patients (7.6%) with occasional symptoms requiring treatment with histamine-2 receptor antagonists (H2RAs), 12 patients (11.4%) with occasional symptoms requiring treatment with proton pump inhibitors (PPIs), as needed, and 33 patients (31.3%) with sustained symptoms needing daily maintenance with PPIs.
  
  
  CONCLUSIONS
  Nearly 50% of patients in Taiwan with endoscopic esophagitis still required treatment 7 years after diagnosis. Approximately 31% of patients still required daily acid suppression therapy. Presence of hiatal hernia and the severity of esophagitis at initial endoscopy independently were predictive of those who would require long-term acid suppression therapy.
