The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide.
Achieving optimal eradication of H. pylori has proven difficult. Combination regimens that use two or three antibiotics with a proton pump inhibitor and/or bismuth are required to achieve adequate rates of eradication and to reduce the number of failures due to antibiotic resistance. In the United States, up to 50% of strains are resistant to ...
Vonoprazan, sold under the brand name Voquezna among others, is a first-in-class potassium-competitive acid blocker medication. [2] [1] Vonoprazan is used in form of the fumarate for the treatment of gastroduodenal ulcer (including some drug-induced peptic ulcers) and reflux esophagitis, and can be combined with antibiotics for the eradication of Helicobacter pylori.
Proton-pump inhibitors and antibiotics should be discontinued for at least 30 days prior to testing for H. pylori infection or eradication, as both agents inhibit H. pylori growth and may lead to false negative results. [135] Testing to confirm eradication is recommended 30 days or more after completion of treatment for H. pylori infection.
Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. [1] The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide .
The European Helicobacter Pylori Study Group published the Maastricht 2-2000 Consensus Report, suggesting a "test-and-treat" strategy for H. pylori in young patients without atypical symptoms. This strategy advocates the use of noninvasive testing to evaluate for H. pylori and simply treating if found, even in the absence of ulcer disease ...

Lansoprazole is used for treatment of: [3] Ulcers of the stomach and duodenum, and NSAID-induced ulcers; Helicobacter pylori infection, alongside antibiotics (adjunctive treatment), treatment to kill H. pylori causing ulcers or other problems involves using two other drugs besides lansoprazole known as "triple therapy", and involves taking twice daily for 10 or 14 days lansoprazole ...
