Abstract

Methods: Adult outpatients with Los Angeles grade C or D esophagitis were allocated to open-label 40 mg IR-OME once a day for 8 weeks in a prospective, randomized, parallel design, single center study. Esophagogastroduodenoscopy (EGD) and validated self-report symptom questionnaires were completed at baseline and follow-up. Intention-to-treat and per-protocol analyses were performed.

Results: Ninety-two of 128 (72 %) eligible subjects participated [64 (70 %) male, mean age 58 (range 19–86), median BMI 29 (range 21–51), 58 C:34 D]. Overall, 81 (88 %) subjects healed [n = 70 (76 %)] or improved [n = 11 (12 %)] erosions. There was no significant difference (morning vs. night) in mucosal healing [81 vs. 71 %, (p = 0.44)] or symptom resolution [heartburn (77 vs. 65 %, p = 0.12), acid regurgitation (82 vs. 73 %, p = 0.28)]. Prevalence of newly identified Barrett’s esophagus was 14 % with half diagnosed only after treatment.

Conclusions: Once-daily IR-OME (taken morning or night) effectively heals severe reflux esophagitis and improves GERD symptoms. Results support the clinical practice recommendation to repeat EGD after 8 weeks PPI therapy in severe esophagitis patients to assure healing and exclude Barrett’s esophagus.

Background: Morning dose or twice-daily proton pump inhibitor (PPI) use is often prescribed to heal severe reflux esophagitis.

Aim: Compare the effect of single dose morning (control arm) versus nighttime (experimental arm) omeprazole/sodium bicarbonate (Zegerid®) (IR-OME) on esophagitis and gastroesophageal reflux symptoms.
