title: Helicobacter treatment with quadruple therapy in primary health care for patients with a history of ulcer disease.
abstract: BACKGROUND
  Few patients with a history of peptic ulcer are treated by their GP for H. pylori infection, even though theoretical evidence supports such an approach.
  
  
  OBJECTIVE
  We aimed to determine the validity of this recommendation and to test the feasibility of quadruple therapy in primary health care.
  
  
  METHODS
  In this prospective, non-randomized intervention study, 51 unselected patients with a history of proven ulcer disease received a 7-day quadruple therapy (lansoprazole, colloidal bismuth subcitrate, tetracycline and metronidazole) from their GP. Main outcome measures were: (i) endoscopically confirmed cure of the infection; (ii) results of serology at entry and at 6 months follow-up; (iii) quality of life at entry, at 6 weeks and at 6 months follow-up; (iv) gastric symptoms at entry, at 6 weeks and at 6 months follow-up; and (v) medication at entry and at 6 months follow-up.
  
  
  RESULTS
  Quadruple therapy was well tolerated and there were no drop-outs with this regimen. Intention to treat cure rate was 48/51 (94%, 95% CI 87-100%), per protocol cure rate was 48/49 (98%, 95% CI 94-100%). 45/50 (90%) had positive serology at entry. IgG antibody titres decreased > 40% in 95.2% of patients. Quality of life improved significantly after treatment, gastric symptoms decreased and medication use decreased.
  
  
  CONCLUSIONS
  GPs should be encouraged to identify patients with a history of ulcer disease and chronic use of acid suppressants and offer them treatment for H. pylori infection. This approach will cure the infection in almost all patients, it will improve the quality of life and decrease costs. Quadruple therapy does not lose efficacy when employed in primary care. Pre-treatment serological testing is potentially useful for narrowing down the treatment group to those with actual infection, and serology is promising as an easy and cheap follow-up instrument in primary health care.
