Background/Aims: Gastro-esophageal reflux disease (GERD) is a chronic condition, with 50-80% of patients experiencing recurrence within one year following completion of initial treatment. The present study aimed to estimate recurrence rate and treatment response in GERD patients treated with proton pump inhibitor.
Methods: A total of 207 symptomatic GERD patients, which were confirmed by endoscopy from July 2008 till January 2009, were enrolled. They were divided into non-erosive reflux disease (NERD) group and erosive reflux disease (ERD) group by endoscopic findings. Patients were treated with lansoprazole 15 mg (NERD group) or 30 mg (ERD group) once daily for 8 weeks. The presence of symptoms was assessed in each patient at baseline and post-treatment using a questionnaire. Subsequent symptomatic recurrence on the cessation of therapy in each improved patients was checked by telephone survey or outpatient interview.
Results: Ninety-four patients and 113 patients were first diagnosed with NERD and ERD, respectively. The mean post-treatment follow-up period was 24.4+/-8.5 weeks. Recurrence rate was 40.0% (NERD, 43.8%; ERD, 37.1% (p=0.224)). Recurrence time was 10.1+/-weeks (NERD 9.6 weeks; ERD, 10.6 weeks (p=0.444)). Regarding the symptom improvement after 8 week therapy with lansoprazole, 89.4% (NERD, 85.1%; ERD, 92.9% (p=0.056)) of total patients were symptomatically improved.
Conclusions: Forty percentage of GERD patients recurred within 6 months following the completion of 8 week therapy with lansoprazole. Recurrence rate, recurrence time, and rate of symptom improvement were not significantly different between NERD group treated with half dose and ERD group treated with full dose lansoprazole.
