Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Bismuth agent quadruple therapy (including bismuth agent and proton pump inhibitor combined with two antibiotics) is the first-line strategy to eradicate Helicobacter pylori in China. However, it may cause a series of adverse reactions, such as nausea, diarrhea, abdominal pain, constipation, and abnormal taste, etc., which leads to a decrease in patient compliance, thereby affecting the treatment effect. Many studies have found that adding probiotics to traditional Helicobacter pylori eradication therapies increase eradication rates and reduce the side effects of the treatment. Bifidobacterium tetrad live bacteria tablet is a compound microecological preparation composed of bifidobacterium infantis, lactobacillus acidophilus, enterococcus faecalis and bacillus cereus. This study aims to observe the clinical efficacy of Bifidobacterium quadruple live bacteria tablets (Si Lian Kang) on reducing the incidence rate of adverse reactions in Helicobacter pylori quadruple eradication therapy and on the effects of gastrointestinal flora.
