title: Can lansoprazole, amoxicillin, and clarithromycin combination still be used as a first-line therapy for eradication of helicobacter pylori?
abstract: OBJECTIVE
  To determine H. pylori eradication rate with lansoprazole-amoxicillin-clarithromycin treatment regimen, which is the most frequently used as first-line therapy, in the Kirikkale region.
  
  
  METHODS
  One hundred and five patients (44 male, 61 female) with H. pylori infection were included in the study. Patients were divided into two groups based on the endoscopic findings: non-ulcer dyspepsia (n=84, 31 male, 53 female) and acute gastric or duodenal ulcer (n=21, 13 male, 8 female) groups. The diagnosis of H. pylori infection was confirmed if both the urease test and histological examination, which were performed on endoscopic biopsies, were positive. Lansoprazole 30 mg, amoxicillin 1 g, and clarithromycin 500 mg were given twice daily for 14 days to all patients. Endoscopic biopsies were repeated for the evaluation of eradication three months after the treatment.
  
  
  RESULTS
  Ninety-six patients completed the study. Eradication rates were found to be 45.8% (44 of 96) in all patients, 42.1% (32 of 76 patients) in the non-ulcer dyspepsia group and 60% (12 of 20 patients) in the gastric or duodenal ulcer group for per protocol analysis, and the difference between non-ulcer dyspepsia and gastric or duodenal ulcer groups was not statistically significant (p=0.208).
  
  
  CONCLUSIONS
  Lansoprazole-amoxicillin-clarithromycin treatment regimen, the most frequently preferred regimen in H. pylori eradication, is ineffective in our region. The low eradication rates observed with lansoprazole-amoxicillin-clarithromycin, at least in our region, bring into question its use as a first-line therapy. The use of alternative treatment protocols or antibiotic susceptibility test before the treatment may be helpful in achieving successful eradication with first-line therapy.
