Clinical Trial Summary

Both hybrid and high-dose dual therapies developed by the scholars from Taiwan can achieve a high eradication rate for clarithromycin-resistant strains, and have a great potential to replace bismuth quadruple therapy in the treatment of H. pylori infection.

Description:

Bismuth quadruple therapy has been recommended as a choice of the first-line treatment for H. pylori infection in several important international consensuses. However, it is associated with a high frequency of adverse events. Both hybrid and high-dose dual therapies developed by the scholars from Taiwan can achieve a high eradication rate for clarithromycin-resistant strains, and have a great potential to replace bismuth quadruple therapy in the treatment of H. pylori infection. In the second-line treatment, tetracycline-levofloxacin quadruple therapy developed by our study group can achieve a higher eradication rate than levofloxacin triple therapy for salvage treatment of hybrid therapy. However, whether the new therapy can be a promising rescue treatment for bismuth quadruple or high-dose dual therapy remains unanswered.
