다국어 초록 (Multilingual Abstract)

Backgroud : Today, the eradication of H. pylori represents a generally accepted and beneficial therapeutic strategy for treatment and prevention of peptic ulcer relapse. Major factors that have affected H. pylori eradication are eradication rate of regimen, compliance of patients and complications of drugs. Recently, the combination of omeprazole, amoxicillin and clarithromycin has been accepted as one of the most effective treatment for the eradication of H. pylori. The primary aim of this study was to evaluate the efficacy of this therapeutic modality in Korean patients. Methods : Two hundred twenty three patients with peptic ulcer and H. pylori infection were taken two types of triple therapy. Group A were treated with omeprazole 20 mg bid, amoxicillin 500 mg tid, clarithromycin 500 mg tid daily for 14 days. Group B were treated with omeprazole 20 mg bid, amoxicillin 1g bid, clarithromycin 500 mg bid daily for 7 days. Endoscopy with H. pylori tests was repeated 4 weeks after the end of treatment and then biopsy specimens were taken in antrum and body. CLO test and Warthin Starry silver stain were conducted concordantly. Results : The H. pylori eradication rate was 92.5% in group A, 90.4% in group B. There was no significant difference in eradication rate. More than 50% of ulcer size reduction was observed 90.5% in group A, 86.3% in group B. There was no significant difference in ulcer healing(p > 0.05). The incidence of all side effects in both group were as follows; 22.6% in group A, 19.1% in group B. But major side effect was found only group A, of whom the symptom was too serious for the treatment to continue. Conclusion : We concluded that the seven days regimen was more favorable, because the eradication rate was almost the same as the 14 days regimen. And drug compliance and cost effectiveness were better than 14 days treatment regimen.(Korean J Med 58:626-631, 2000)
