LID - 10.2174/1574886312666170310100209 [doi] AB - BACKGROUND: Standard triple therapy with the proton pump inhibitors, clarithromycin and amoxicillin for Helicobacter pylori infection is considered to be safe; however, the development of significant adverse events (AEs), such as skin rashes, has been reported. OBJECTIVE: To reconfirm the safety of this treatment. METHODS: This was a retrospective cohort study. After the exclusion of patients allergic to penicillin, 322 consecutive patients, consisting of 305 outpatients and 17 inpatients, had received the first-line eradication treatment with lansoprazole (30 mg), clarithromycin (200 mg), and amoxicillin (750 mg) twice daily for 7 days. Their medical charts were reviewed, and data were collected. RESULTS: Three patients discontinued the treatment because of the development of a skin rash, mild diarrhea, and heat sensation, respectively. The main AE observed was mild diarrhea in 50 patients. One patient had frequent diarrhea, but it was readily resolved by a probiotic treatment. On the second or third day after the conclusion of the treatment, a skin rash also occurred in six patients (2%). Two of these patients and one patient who discontinued the treatment were administered steroids as outpatients. They recovered within 1 month. CONCLUSION: Most AEs that developed were mild, except for some cases of a rash. Rashes developed in spite of the exclusion of penicillin-allergic patients and mainly after the completion of the one-week treatment. As a consequence of little previous exposure to penicillin in the Japanese population, the development of delayed rashes after this exclusion may represent first sensitization to penicillin.
