What is H. pylori quadruple therapy?

Ten-day quadruple therapy comprising low-dose rabeprazole, bismuth, amoxicillin and tetracycline is an effective and safe first-line treatment for Helicobacter pylori infection in population with high antibiotic resistance: a prospective, multicenter, randomized, parallel-controlled clinical trial in China.

What is the gold standard test for H. pylori?

Use of Urea breath test (UBT) is often considered as the gold standard test in the diagnosis of H. pylori infection[114-116].

Is a breath test more accurate than a stool test for H. pylori?

Studies varied in the limit they used before saying a test was positive for H pylori infection and the type of stains used to examine the biopsy material. When we looked at all the data we found that urea breath tests were more accurate than blood and stool tests.

How effective is quadruple therapy for H. pylori?

A 7-d quadruple therapy consisting of rabeprazole (20 mg bid) amoxicillin (1.0 g, bid) levofloxacin (0.2 g, bid) and furazolidone (0.1 g, bid), has high efficacy in the treatment of H. pylori infection with an eradication rate of 86% by intention-to-treat analysis and 94% by per-protocol analysis.

What if urea breath test is positive?

If the urea breath test is positive and the isotope is detected in the breath, it means that H. pylori is present in the stomach. If the isotope is not found in the breath, the test results are negative for the infection.

How accurate is a stool test for H. pylori?

This implies that on average, given a specificity of 0.90 and prevalence of 53.7% (median specificity and prevalence in the studies), out of 1000 people tested for H pylori infection, there will be 46 false positives (people without H pylori infection who will be diagnosed as having H pylori infection).

How long is quadruple therapy?

Conclusions: Four days of quadruple therapy after omeprazole pre-treatment is a feasible, well tolerated, and effective treatment for H. pylori infection, especially in those carrying a metronidazole-sensitive strain. It seems that in quadruple therapy, cure rate and treatment duration have a non-linear relation.

Is Helicobacter pylori serious?

For most people the infection won’t cause them any problems. But in some, H. pylori can cause long-lasting irritation, swelling and pain in the stomach (known as ‘severe chronic atrophic gastritis’ or SCAG) and stomach ulcers. This can lead to cancer.

What is eradication of Helicobacter pylori?

Eradication is defined as the presence of negative tests for H pylori4 weeks or longer after the end of antimicrobial therapy. Clearance or suppression of H pylorimay occur during therapy, and failure to detect H pylorion tests done within 4 weeks of the end of therapy may give false-negative results.
