Helicobacter Pylori Eradication With Berberine Quadruple Therapy Versus Clarithromycin Quadruple Therapy

Xijing Hospital of Digestive Diseases566 enrolled

Overview

This study aims at evaluating efficacy and safety of berberine-containing quadruple therapy(berberine, lansoprazole, bismuth and amoxicillin) versus clarithromycin-containing quadruple therapy (clarithromycin,lansoprazole, bismuth and amoxicillin) in H. pylori eradication. It is hypothesized that berberine-containing quadruple therapy is non-inferior to clarithromycin-containing quadruple therapy. Patients with confirmed H. pylori positive status will be randomized to one of the treatments described above. At week 2 and 6 follow-up visits, a urea breath test(UBT) will be performed to confirm eradication.

The study will include three phases: screening, treatment and follow-up. Screening: this phase will last a maximum of 28 days and subjects eligibility will be evaluated after informed consent signature. Endoscopy and Urea Breath test will be performed in addition to the baseline routine evaluations. Treatment: Subjects are randomly assigned to treatment and will be treated for 14 days. A randomization visit will take place on Day 0 and an end-of-treatment visit will take place between day 12 and 14. Follow-up: includes two visits. approximately 14 days of treatment and 28 days after the end of treatment. Eradication of H. Pylori will be confirmed through urea breath test(UBT).

Outcomes

Primary Outcomes

helicobacter pylori eradication

The primary end point of this study is H.pylori eradication,established by negative \[13C\] urea breath test 28 days after the end of eradication.

Time frame: 28 days after treatment

Secondary Outcomes

symptoms effective rates

Evaluation effective rate of symptoms 2 weeks of treatment and 4 weeks after the end of treatment. Symptom effective rate =（total score before treatment - total score after treatment）/total score before treatment x 100%. Total score = frequency + severity. Frequency score is calculated by all the frequency of heartburn, reflux, abdominal pain, and flatulence. Severity is accumulated by the degree of symptoms described above, which is divided to 4 degree as 0 presenting none, and 3 presenting most severe

Time frame: 14 days of treatment, and 28 days after treatment

adverse events

Participants with Adverse Events as a Measure of Safety and Tolerability.The common side effects of the study include headache, dizziness, skin rash, other gastrointestinal disorders, pyrexia, cough and back pain.
