Recent advances in the treatment of GERD in the elderly: focus on proton pump inhibitors.

The prevalence of gastroesophageal reflux disease (GERD) increases with age, and older people are more likely to develop severe disease. Studies of elderly patients with GERD indicate differences in presentation and diagnosis, compared with GERD in younger adults. Indeed, an older patient with GERD may present with atypical symptoms such as dysphagia, vomiting, weight loss, anaemia and anorexia, and less frequently with typical symptoms such as heartburn or acid regurgitation. These findings are attributed to pathophysiological changes in esophageal function that occur with age. Therefore, GERD in elderly patients is more likely to be poorly diagnosed or undiagnosed. Although few studies have concentrated specifically on elderly patients, the proton pump inhibitors (PPIs) have been shown to be more effective than histamine receptor antagonists for healing reflux esophagitis and for preventing its recurrence when they are given as maintenance therapy. In addition, the PPIs seem to be safe both in short- and in long-term therapy of elderly patients with GERD.
