Condition(s) studied

Investigational drug(s) / intervention(s)

Bismuth: Bismuth-containing quadruple therapy: given for 14 days at a dose of bismuth 110 mg 2 capsules BID plus esomeprazole 20 mg 1 tablets BID#tetracycline 250mg 2 capsules TID and furazolidone 100mg 1 tablets BID

Esomeprazole: Bismuth-containing quadruple therapy: given for 14 days at a dose of esomeprazole 20mg 1 tablets BID plus bismuth 110 mg 2 capsules BID#tetracycline 250mg 2 capsules TID and furazolidone 100mg 1 tablets BID

Tetracycline: Bismuth-containing quadruple therapy:given for 14 days at a dose of tetracycline 250mg 2 capsules TID plus furazolidone 100mg 1 tablets BID#esomeprazole 20 mg 1 tablets BID and bismuth 110 mg 2 capsules BID

Furazolidone: Bismuth-containing quadruple therapy:given for 14 days at a dose of furazolidone 100mg 1 tablets BID plus tetracycline 250mg 2 capsules TID#esomeprazole 20 mg 1 tablets BID and bismuth 110 mg 2 capsules BID

Saccharomyces Boulardii Oral Powder: Saccharomyces boulardii combined with Bismuth-containing quadruple therapy:given for 14 days at a dose of Saccharomyces boulardii powder 250 mg 2 packets BID#bismuth 110 mg 2 capsules BID plus esomeprazole 20 mg 1 tablets BID#tetracycline 250mg 2 capsules TID and furazolidone 100mg 1 tablets BID

Study summary

This study aims at evaluating efficacy and safety of Saccharomyces boulardii combined with bismuth-containing quadruple Therapy versus bismuth-containing quadruple Therapy(bismuth#esomeprazole#tetracycline and furazolidone) in H. pylori rescue therapy. It is hypothesized that Saccharomyces boulardii combined with bismuth-containing quadruple Therapy is superior to bismuth-containing quadruple Therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. At week 6 follow-up visits, a urea breath test#rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.

Eligibility

Primary outcome measure(s)

• Helicobacter pylori eradication — 28 days after treatment
  The primary end point of this study is H.pylori eradication#established by negative \[13C\] urea breath test #DOB value below 3.9#28 days after the end of eradication
