Helicobacter pylori Infection in Patients with Erosive Esophagitis Is Associated with Rapid Heartburn Relief and Lack of Relapse After Treatment with Pantoprazole

Previous studies have shown an increased effect of proton pump inhibitors on intragastric pH in Helicobacter pylori (HP)–infected patients suffering from gastroesophageal reflux disease (GERD). We evaluated the effect of HP infection on healing and symptom relief in GERD patients with erosive esophagitis treated with pantoprazole. Two hundred twenty-seven patients with endoscopically proven reflux esophagitis were treated for 8 weeks with pantoprazole, 40 mg daily. Patients achieving endoscopic healing at that time were treated for 16 weeks more with pantoprazole, 20 mg daily. Healing and symptom relief rates for HP infection were compared. We found complete relief of heartburn in 72.3% of the HP-positive versus 58.8% of the HP-negative group (P < 0.05). Overall prevalence of heartburn at 8 weeks was higher in the HP-negative group (40.3 vs. 25.8%; P < 0.05), with no significant differences in endoscopic healing (overall 80.4%). At 24 weeks of treatment, the symptomatic relapse rate was higher in the HP-negative group (25.9 vs. 10.2%; P < 0.020). At 8 weeks, patients with erosive esophagitis and HP infection exhibited a significantly better response to pantoprazole through complete heartburn relief, with no differences in endoscopic healing rates between the groups. After 24 weeks, the relapse rate was significantly higher in the HP-negative group.
