This pilot study aims to estimate the prevalence of Helicobacter pylori (H. pylori) colonization in patients presenting with non-specific abdominal pain (NSAP) in an urban academic emergency department (ED) located in Washington, DC.

Condition Intervention
Peptic Ulcer
Peptic Ulcer Perforation
Stomach Ulcer
Other: Urea Breath Test (UBT) for H. pylori infection

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Pilot Study to Estimate the Prevalence of Helicobacter Pylori (H. Pylori) Infection in Patients Presenting With Non-specific Upper Abdominal Pain to the Emergency Department (ED.)

Further study details as provided by George Washington University:

Primary Outcome Measures:
  • Prevalence of H. pylori infection in ED patients with symptomatic abdominal pain [ Time Frame: 6 momths ]
    Prevalence of H. pylori infection diagnosed by UBT in patients with symptomatic upper abdominal pain treated in the ED.

Secondary Outcome Measures:
  • SES measures [ Time Frame: 6 months ]
    DoeS SES correlate with HP infection?

Enrollment: 212
Study Start Date: March 2011
Study Completion Date: March 2015
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Non specific upper abdominal pain
Cohort is patients who present to the Emergency Department with primary complaint of upper abdominal pain without obvious cause.
Other: Urea Breath Test (UBT) for H. pylori infection
13C UBT to detect H. pylori infection. Single bedside test that determines infection in about ten minutes. Test machine is a product of Exalenz bioscience.
Other Names:
  • 13C
  • UBT
  • H. pylori
  • helicobacter
  • gastric
  • ulcers
  • dyspepsia
  • emergency
  • abdominal pain
  • exalenz

Detailed Description:
The major goal is to study the prevalence of H. pylori using the 13C Urea Breath Test (UBT) in emergency department (ED) patients with non-specific abdominal pain. The investigators plan to enroll 250 patients during the pilot stage of this study. This T2 translational trial aims to apply recommended guidelines for the investigation and management of NSAP and dyspepsia into the practical arena of ED clinical care. The "test-and-treat" approach to symptomatic H. pylori infection has been endorsed by the American Gastroenterological Association (AGA). Patients who test positive for H. pylori by UBT will be treated with clarithromycin-based triple medication therapy as recommended by the American College of Gastroenterology (ACG) at the discretion of the treating physician. The rationale is that successful identification of H. pylori in the ED and initiation of treatment may reduce future risk of gastritis, gastric lymphoma, and gastric cancer, and is cost-effective through reduction of future healthcare costs and symptom severity. Study subjects will be followed for medication compliance, resolution of symptoms, and ability to obtain outpatient follow-up. As part of this study, the investigators will be collecting important information on the ED evaluation of abdominal pain.

  • Patient does NOT speak English NOR has reliable adult translator.
  • Patient does NOT have capacity to give consent? (confused/intoxicated/etc.)
  • The patient currently is on antibiotics.
  • The patient currently is on a PPI. (eg. Prilosec [omeprazole]), protonix [pantoprazole], prevacid [lansoprazole], aciphex [rabeprazole], nexium [esomeprazole]
  • The patient has taken bismuth or pepto-bismol today.

  • The patient UNABLE to walk to H.pylori Breath test.
  • The patient had "recent" negative H.pylori test for same symptoms.
  • There an "obvious alternative cause" for pain (per attending).
