Abstract:

The efficacy of histamine H2 receptor antagonist (H2RA) and proton pump inhibitor (PPI) therapies in healing reflux esophagitis was compared in a prospective randomized case-control comparative study. A total of 71 patients with grade A to D esophagitis (Los Angeles classification) were given either famotidine 20 mg twice a day (Fam; n = 35) or omeprazole 20 mg once daily (Ome; n = 36) for 8 weeks. Endoscopy was performed to assess healing in 57 patients. Healed patients were followed-up without H2RA or PPI therapy for 3 months. At the end of follow-up, endoscopy was able to be performed in 33 patients. Healing rates for patients in the Fam and Ome groups were 58.6% (17/29) and 97.4% (27/28), respectively (P < 0.001), and when limited to grade A to B, healing rates were 60.9% (14/23) and 100% (25/25), respectively (P < 0.001). Concerning Helicobacter pylori infection, healing rates for the Fam and Ome groups in H. pylori (+) patients were 90.0% (9/10) and 90.9% (10/11), respectively (P = 1.00). Remission rates in the Fam and Ome groups were 45.0% (9/20) and 33.3% (6/18), respectively (P > 0.4). In regard to alcohol drinking, remission rates of daily and social drinkers were 7.7% and 42.4%, respectively (P < 0.03). Thus, PPI should be the drug of choice even for healing lower-grade reflux esophagitis, especially in H. pylori (−) patients. Treatment with H2RA may be an alternative choice in H. pylori (+) patients. After healing, most patients cannot sustain remission without maintenance therapy.
