Core Tip

Core tip: The Helicobacter pylori eradication rate is decreasing worldwide, and there is a lack of recent data from China. The current study of 14-d quadruple regimens in Eastern China revealed an eradication rate of 76.6%. Amoxicillin-containing regimens had the highest eradication rate in primary therapy, and amoxicillin- and furazolidone-containing regimens showed superiority in rescue therapy. Age, prior therapy, and use of omeprazole or pantoprazole were independent risk factors for eradication failure. This study can improve the choice of antibiotics and proton pump inhibitors and indicates that in clinical practice, attention should be paid to elderly patients and rescue therapy.
