Background:Helicobacter pylori (H. pylori) infection is the main cause of most PUD;
therefore, the eradication of H. pylori is extremely important in the treatment of PUD. There are
several recommended treatment regimens suggested to eradicate this organismAim:This study compared the efficacy of three anti-Helicobacter pylori regimens in patients with
dyspepsia or peptic ulcer disease (PUD).Objective:The objective of this study was to assess the efficacy of three anti-H pylori treatments
in patients based on C14 urease breath test (C-UBT) results, drug compliance, and adverse effects.Methods:This randomized, open-label clinical trial included 136 H. pylori-infected patients without
prior treatment. Patients were randomly divided into three groups. The OAC group received
20 mg Omeprazole capsules twice a day, two 500 mg Amoxicillin capsules twice a day, and 500
mg Clarithromycin capsules twice a day for 14 days. The OAL group received 20 mg Omeprazole
capsules twice a day, two 500 mg Amoxicillin capsules twice a day, and Levofloxacin 500 mg capsules
twice a day for 14 days. The OAMB group received 20 mg Omeprazole capsules twice a
day, two 500 mg Amoxicillin capsules twice a day, Metronidazole 500 mg three times a day, and
Bismuth 240 mg twice a day for 14 days. Evaluation for compliance and drug-related adverse effects
were assessed at the end of two weeks. H. pylori eradication was evaluated eight weeks after
treatment using the C-UBT.Results:A total of 136 patients participated in this study, and their groups were matched based on
age and sex. The results of the C-UBT test showed that the eradication rate of H. Pylori was
82.2%, 91.3%, and 97.3% for the three-drug OAC, OAMB, and OAL treatment regimens, respectively.
Moreover, all the regimens showed high compliance among the patients. Only OAC and
OAL showed a significant difference in the H. Pylori eradication rate, and no superiority was
found between OAMB and OAL or OAC therapies.Conclusion:The regime of OAL achieved a satisfactory rate of H. pylori infection eradication
with good tolerance in patients with PUD, without any acute side effects.
