First‐line Bismuth‐containing Five‐day Concomitant Quintuple Therapy for Helicobacter Pylori Eradication
2016
Background
Widespread use of antibiotics has resulted in increased rates of antibiotic resistance and decreased rates of Helicobacter pylori (H. pylori) eradication, leading to a search for newer therapeutic options. This study aimed to examine the efficacy, tolerability, and patient compliance of a first-line bismuth-containing 5-day concomitant quintuple therapy.
Materials and Methods
This prospective study included 144 eradication treatment naive H. pylori positive patients with dyspeptic complaints. Patients received the following concomitant quintuple therapy for 5 days: bismuth subcitrate 300 mg q.i.d, omeprazole 20 mg b.i.d, clarithromycin 500 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg t.i.d. Eradication was assessed with H. pylori stool antigen test or urea-breath test 6 weeks after the completion of therapy.
Results
Treatment compliance rate in this study was 97.2%. Intention to treat and per-protocol eradication rates were 134/144 (93.1%, 95% CI, 88.9–97.2) and 134/140 (95.7%, 95% CI, 92.2–98.6), respectively. Side effect was reported by 8.5% of the patients that attended follow-up visits, including epigastric pain (2.8%), nausea/vomiting (2.1%), diarrhea (1.4%), taste disturbance (1.4%), and fatigue (0.7%).
Conclusions
Bismuth-containing, short course, quintuple concomitant therapy appears to be an effective and safe therapeutic option for the first-line H. pylori eradication, particularly in populations with high resistance.
