Abstract

BACKGROUND:

Two-thirds of proton pump inhibitor prescribing in the UK is for long-term therapy.

AIM:

To determine the impact of eradication in long-term proton pump inhibitor users infected with Helicobacter pylori.

METHODS:

A total of 184 H. pylori-positive patients were randomly assigned to true or placebo eradication therapy. The primary outcome was the change in proton pump inhibitor usage measured by prescriptions; secondary outcomes were changes of proton pump inhibitor doses, dyspepsia symptoms, general practitioner consultations and quality of life measures.

RESULTS:

In the year following H. pylori eradication proton pump inhibitor prescriptions fell compared with placebo (-1.7, 95% CI: -2.3 to -1.1, P < 0.001); when adjusted to full-dose equivalent prescriptions the reduction was more marked (-2.2, 95% CI: -3.0 to -1.4, P < 0.001). Both general practitioner consultations (-1.0, 95% CI: -1.8 to -0.1, P = 0.026) and symptoms measured on the Leeds Dyspepsia Questionnaire (-3.1, 95% CI: -5.3 to -0.9, P = 0.005) were reduced. Quality of life and self-rating measures also favoured eradication (EQ-5D: 0.09, P = 0.08 and VAS: 5.6, P = 0.002). The Carlsson and Dent Reflux Questionnaire found no difference between groups (-0.3, P = 0.65), possibly balancing decreased overall symptoms with increased prominence of heartburn in the eradication group.

CONCLUSIONS:

Helicobacter pylori eradication in infected, long-term proton pump inhibitor users in primary care reduced both the overall severity of symptoms and use of health care.
