Review article: Helicobacter pylori infection in peptic ulcer haemorrhage.

In this overview, medical advice for routine clinical practice regarding peptic ulcer haemorrhage (PUH) is given, based on the extensive literature about Helicobacter pylori and the controversial results about the interaction of H. pylori infection and nonsteriodal anti-inflammatory drug (NSAID) use. PUH remains an important emergency situation with an incidence between 32 and 51/100 000 persons per year. There is a high association between H. pylori infection and peptic ulcer disease. The association between H. pylori infection and PUH is less clear, but a strong argument for the aetiological role is the fact that eradication of H. pylori decreases recurrence of bleeding. NSAID use is another important risk factor for PUH. H. pylori infection and NSAID use seem to act independently, although some studies show a synergistic interaction while other studies report that H. pylori is protective against the development of PUH in NSAID users. All patients with PUH should be tested for H. pylori infection, regardless of the use of NSAIDs. Because invasive tests are less sensitive in PUH patients, negative tests in patients with no other risk factors should be confirmed by serology or urea breath test (UBT). Eradication therapy with a proton pump inhibitor or ranitidine bismuth citrate-based triple therapy should be given to all H. pylori-positive patients. Only for nonaspirin-NSAID users does the effect of eradication therapy on the healing of gastric ulcers remain controversial, but currently we also advise eradication of H. pylori in this subgroup. After eradication therapy, acid-suppressant therapy is advised to heal the ulcer. The success of eradication should always be confirmed because of the risk of recurrence of peptic ulcer disease and bleeding in H. pylori-infected patients.
