POCone-UBiT-IR300 Pediatric Comparison Study

The purpose of this study is to compare between the POCone® to the UBiT®-IR300 in measuring 13CO2/12CO2 ratio in breath samples when used together with the BreathTek® UBT (urea breath test) Kit and the pUHR-CA web-based software program in identifying H. pylori infection in pediatric subjects.

About this study

The same patients will be tested on both the POCone® and UBiT®-IR300. If the patients test positive for H. pylori, they will be given eradication medication and brought back in for a re-test.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male or female subject ages 3 to 1711/12 years.
  • Subject with upper gastrointestinal signs and symptoms (e.g., abdominal pain/discomfort, bloating, nausea, or vomiting, etc.)
  • Subject and/or parent/legal guardian is capable of giving assent or consent.
  • Subject is able to complete the urea breath test by investigator's assessment.

Exclusion criteria

  • Subject is hypersensitive to mannitol, citric acid and/or aspartame.
  • Previous diagnosis of phenylketonuria (PKU.
  • Subject with difficulty swallowing or who may be at high risk for aspiration due to medical or physical conditions.
  • Subjects with ongoing respiratory conditions or on bronchodilators that may compromise the collection of breath samples.
  • Subjects with severe chronic illness (e.g., Crohn's disease, leukemia, kidney diseases, etc.)
  • Administration of bismuth preparations (e.g., Pepto-Bismol®) at anytime within 14 days prior to the testing.
  • Administration of antibiotics (e.g., amoxicillin, tetracycline, metronidazole, clarithromycin, azithromycin, etc.) therapy at anytime within 14 days prior to the testing.
  • Administration of proton pump inhibitors (PPI; e.g., omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, pantoprazole, etc.) at anytime within 14 days prior to the testing.
  • Administration of Histamine H2 receptor antagonist (H2RA; e.g., ranitidine, cimetidine, famotidine, nizatidine, etc.) at anytime within 24 hours prior to the testing.
  • Treatment for eradication of H pylori within 28 days before testing or retesting.
  • Participation in a drug or device study within 30 days of testing

Treatment and study plan

Pranactin citric solution

Other

All patients were required to drink the pranactic citric solution to diagnose H.pylori.

Primary outcomes

  1. Agreement Between POCone and UBiT-IR300.

    Time frame: Baseline, Post Dose (15 min)

    The study end-points are UHR values derived from DOB (delta over baseline) values obtained from the POCone and UBiT-IR300 (UHRP and UHRU, respectively) at Baseline and Post-Dose. Same patients will be tested on both the POCone and UBiT-IR300.

    Subjects fasted for at least 1 hr prior test. Each patient provided breath samples in 3 blue (Baseline) breath bags-labeled "A" "B" "C". Subjects were given Pranactin-Citric solution (4oz) to drink, waited 15 min and collected 3 pink (post-dose) bags which were paired with the baseline bags in no particular order. Each pair was tested on both machines. The first two available pairs of UHR values were used for data analysis. The 3rd pair was used only if one of the first two samples did not produce a valid test result.

    DOB values were generated by the two instruments for each Baseline and Post Dose pair. UHR values were claculated based on the DOB values and the subject's anthropometric variables (age, gender, ehight and body weight).

Other outcomes

  1. Number of Participants Tested Positive/Negative for H. Pylori

    Time frame: Single Study Visit (1 hour of testing)

    Qualified subjects from clinical sites underwent a standard urea breath test using the BreathTek UBT Kit. Breath samples were analyzed using both the POCone and the UBiT-IR300. DOB values from these two infrared spectrophotometers were converted to respective UHR values using pUHR-CA. The paired UHR values from each subject were evaluated for agreement.

    UHR values of >10 µg/min were considered positive for H. pylori and UHR values of <10 µg/min were considered negative for H. pylori.
