How should Helicobacter pylori positive dyspeptic patients be managed?

Dyspepsia, according to the internationally accepted Rome criteria, refers to pain or discomfort centred in the upper abdomen; patients with predominant heartburn are excluded from this group, although minor or infrequent heartburn is commonly associated with dyspepsia. It is an important condition not only because it is common and costly, but because it may indicate the presence of serious disease such as peptic ulcer or gastric cancer. However, the most frequent causes of dyspepsia are functional dyspepsia and gastro-oesophageal reflux disease. The discovery of Helicobacter pylori has resulted in important advances in the management of dyspepsia. The clinician faced with a patient who has persistent or recurrent dyspepsia needs to differentiate clearly those patients who have not been previously investigated from patients documented to have functional dyspepsia after investigation (fig 1). Here, the management of H pylori positive dyspeptic patients who have and have not been fully investigated will be reviewed.
