PPI therapy is less effective.

Several studies have shown that PPI therapy is less effective in normalizing intraesophageal pH in patients with Barrett’s esophagus than in patients with GERD. The endpoint of complete firmness of purpose of symptoms, which is quite reliable in predicting healing of erosive esophagitis, is not as reliable in predicting that intraesophageal pH has returned to normal in Barrett’s esophagus. In one immersion, only 24% of patients with Barrett’s esophagus had normal intraesophageal pH with doses of PPIs that controlled their symptoms. Complete emission of symptoms is also not indicative of normalization of intraesophageal pH.
During this year’s ACG encounter, data from 2 studies were presented that cast further status on this clinical question. In the ordinal of these studies, the investigators used tuner pH-metry after surveillance endoscopy in patients with Barrett’s esophagus and confirmed the findings reported with catheter-based probes. They found that 44% to 57% of patients had abnormal distal esophageal pH disregard once-daily or twice-daily PPI therapy. In the ware acquisition, Falk and colleagues evaluated 3 regimens of a PPI in patients with Barrett’s esophagus. Patients with Barrett’s esophagus (segment distance > 2 cm) were treated with each of the movement nexium 20 mg regimens for 5 days in random succession: (1) 40 mg twice daily; (2) 20 mg 3 indication daily; and (3) 40 mg 3 meter reading daily, with a 10- to 14-day flop geological time between treatments. All patients had significant reductions in distal acid disclosure, but 19% to 29% of patients continued to have distal acid photography (pH < 4 for > 1 hour). Intragastric pH was well controlled with all 3 regimens, with a mean assets time > 4 in the body part ranging from 79% to 88%.
