A short-term eradication therapy for Helicobacter pylori acute gastritis
Abstract
BACKGROUND AND AIMS: Acute gastritis, caused by an initial infection of Helicobacter pylori (H. pylori), may resolve spontaneously, but the infection sometimes becomes chronic. We examined the efficacy of a short-term H. pylori eradication therapy on acute gastritis.
METHODS: Among the 15 patients with hemorrhagic acute gastritis who were randomly allocated to group A (eradication therapy) or group B (Lansoprazole, LPZ), 10 of them started to receive treatment within 1 day after the disease onset. The other five patients began the eradication therapy 4-6 days after disease onset (group C). Eradication therapy consisted of a daily oral administration of each of 30 mg lansoprazole (LPZ), once a day; 400 mg clarithromycin, twice a day; 1000 mg amoxicillin, twice a day; and 300 mg rebamipide, three times a day, for one week. If the endoscopy was normal, medication was stopped for the following 4 weeks before gastric endoscopy was performed again in order to assess H. pylori eradication.
RESULTS: All group A patients were cured after the 1-week treatment and therefore, they became H. pylori negative. Group B and C patients had erosions or ulcers after the 1-week treatment and so received an additional 3-week administration of LPZ. Four weeks later, their gastritis was cured and except for one group B patient, they became H. pylori-negative.
CONCLUSION: In patients with acute gastritis, caused by an initial H. pylori infection, eradication therapy was efficacious in achieving…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 15 participants or records.
