Helicobacter pylori eradication may prevent peptic ulcer bleeding among elderly on regular aspirin

Aspirin in low doses is a very useful preventative drug in people at high risk of strokes or heart attacks. However, on rare occasions, it can provoke internal ulcer bleeding.By thinning the blood, aspirin makes ulcers in the stomach bleed. These ulcers may be caused by a particular type of bacteria, helicobacter pylori.

Researchers have found in a new HEAT (Helicobacter pylori Eradication Aspirin) trial that Helicobacter pylori eradication may prevent peptic ulcer bleeding in older patients on regular aspirin.

The results of the trial are published in The Lancet.

The STAR (Simple Trials for Academic Research) team from the University of Nottingham investigated whether a short course of antibiotics to remove Helicobacter pylori bacteria would reduce the risk of bleeding in aspirin users.

The .HEAT (Helicobacter pylori Eradication Aspirin) Trial was a very large trial conducted in 1,208 UK general practices. It was a real-life study which used clinical data routinely stored in GP and hospital records, instead of bringing patients back for follow up trial visits.

The team wrote to 188,875 patients who were taking aspirin and 30,166 volunteered and took part in the study. Those who tested positive for H. pylori were randomised to receive antibiotics or placebos (dummy tablets) and were followed for up to 7 years.

Over the first two and a half years, those who had antibiotic treatment were less likely to be admitted to hospital because of ulcer bleeding than those who had dummy tablets (6 versus 17). Protection occurred rapidly: with those who received placebos (dummy treatment), the first hospitalisation for ulcer bleeding occurred after 6 days, compared to 525 days following antibiotic treatment.

Over a longer time period, protection appeared to wane. However, the overall rate of hospitalisation for ulcer bleeding was lower than expected and this in line with other evidence that ulcer disease is on the decline. Risks for people already on aspirin are low. Risks are higher when people first start aspirin, when searching for H. pylori and treating it is probably worthwhile.

Professor Chris Hawkey said: "Aspirin has many benefits in terms of reducing the risk of heart attacks and strokes in people at increased risk. There is also evidence that it is able to slow down certain cancers. The .HEAT trial is the largest UK-based study of its kind, and we are pleased that the findings have shown that ulcer bleeding can be significantly reduced following a one-week course of antibiotics. The long-term implications of the results are encouraging in terms of safe prescribing."

The results of the trial will be presented at the UEG (United European Gastroenterology) scientific meeting in Vienna where it has won a 10,000 Euro top abstract prize. The STAR team intend to use the prize to sponsor a competition to support a collaboration with a research team that would like to take advantage of STAR methodology.
