Helicobacter Pylori Infection
Conditions
Brief summary
Clinical Study to Confirm Safety and Accuracy in Detection of H. pylori with 13C-Urea Breath Test using the BreathID® Hp and BreathID® Hp Lab Systems in the Pediatric Population
Detailed description
Pediatric subjects with indication for H.pylori testing, will be tested with both stool antigen as a reference standard and a urea breath test using the BreathID® Hp and BreathID® Hp Lab Systems. The BreathID® Hp system continuously measures breath via a nasal cannula and the BreathID® Hp Lab System measures breath collection bags before and after ingestion of a solution with enriched carbon 13 urea and citric acid. The stool sample will be provided within a week of the breath tests and will be analyzed by a central laboratory. Safety and overall efficacy will be assessed.
Interventions
Breath will be analyzed for change in carbon 13 content in breath after ingestion of carbon 13 enriched urea
Breath will be analyzed for change in carbon 13 content in breath after ingestion of carbon 13 enriched urea
Each subject was asked to perform a stool test in parallel to the breath test.
Sponsors
Study design
Masking description
The investigator and treating physician will remain blinded to the breath test results until the end of the study. There is only one arm.
Intervention model description
A 13C labeled substrate is used as part of a combination product; a diagnostic breath test.
Eligibility
Inclusion criteria
* Be older than 3 and younger than 18 years of age * Present with a clinical indication compatible with H. pylori based on the judgement of the treating physician (such as abdominal pain, nausea, diarrhea, reflux, peptic ulcer, dyspepsia, etc., or following treatment for H.pylori) * Subject/Legal guardian (and subject whenever relevant) is willing to sign the Informed Consent/Assent Form * Naïve to H. pylori treatment in the past 6 weeks
Exclusion criteria
* Participation in other interventional trials * PPI or H2 blockers within two (2) weeks prior to breath test/stool antigen test * Pregnant or breastfeeding female * Allergy to test substrates * Antibiotics (not related to H. pylori eradication) and/or Bismuth preparations within four (4) weeks prior to breath test * Exposure to any type of anesthesia, analgesics or sedation 24 hours prior to the breath test. * Exposure to any 13C-enriched substance 24 hours prior to the breath test. * Children 12 years and older - to be excluded after a written notification from the sponsor is received at the site that the limit of 1/3 of the sample size was achieved for this group * Subjects outside US - to be excluded after a written notification from the sponsor is received at the site that the limit of 1/3 of the sample size was achieved for this group

Participant flow
Pre-assignment details
One subject (or parent) signed the consent, but before washout period was completed, decided to withdraw from trial. Therefore, from the 54 consented, only 53 started the study procedure.
