Abstract:

Background.

A large proportion of patients in primary care are still being maintained on long-term acid suppression, without any attempts to identify Helicobacter pylori status and to treat those that test positive. Objectives.

To assess the prevalence and economic and symptomatic benefits of H. pylori eradication in patients maintained on long-term H₂ receptor antagonists (H₂RA) in primary care. Patients and Methods.

Patients on long-term (i.e. 6 months or longer) H₂RA were identified from the computerised records of six practices in north England. Helicobacter pylori status was identified using serology and H. pylori positive patients were then offered standard 7-day proton pump based triple therapy, followed by a urea breath test (UBT) to confirm H. pylori eradication. Those who had a positive UBT were offered a second line course of H. pylori eradication therapy. Follow up period was 1 year. The main outcome measures were improvement in dyspepsia symptom scores, amount of H₂RA being consumed, and economic benefits after H. pylori eradication. Results.

One thousand and seven patients (1.5%) were identified on long-term H₂RA, of whom 471 (46%) ultimately had their H. pylori serology assessed. Sixty-three (297) percent of the patients tested had a positive serology for H. pylori, the majority of whom (58%, 172) had prior evidence of peptic ulcer disease. The mean duration of therapy and mean time since endoscopy/barium studies was significantly longer in patients with peptic ulcer disease compared to their counterparts with nonulcer dyspepsia and gastro-oesophageal reflux disease, p= .0002 and .0001, respectively. After successful H. pylori eradication (which was possible in 84% of the patients), at the end of the 1-year study period, on an intention to treat basis 62% of the patients could either stop or significantly reduce dosage of their H₂RA. There was also significant reduction in the mean dose of H₂RA being consumed and severity of symptoms at the end of the study period (p < .00001). Conclusion.

Almost two-thirds of patients on long-term H₂RA in primary care will have a positive serology for H. pylori; the majority of these will have peptic ulcer disease. In over 60% of cases H. pylori eradication led to significant improvement in symptom scores and reduction in dosage of H₂RA being consumed. Cessation or reduction in long-term H₂RA prescribing is cost effective.
