Brief summary
13C breath di-peptide tests are an effective non-invasive tool to detect pancreatic exocrine function in patients with Chronic Pancreatitis.
Detailed description
The aim of the study is to assess the pancreatic exocrine insufficiency using a 13C labeled di-peptide breath tests in patients with chronic pancreatitis(CP) and show correlation with secretin stimulated endoscopic Pancreatic Function Test (ePFT). Furthermore, a second purpose is to assess the ability to differentiate between non patients with chronic pancreatitis and those without. Approximately 30 subjects will be tested with both methods within two weeks of each other.
Interventions
DRUGbenzoyl-L-tyrosyl-[1-13C]alanine (Bz-Tyr-Ala)
300 mg of powder form dissolved in one cup of tap water prior to breath test

Able to perform the testing and procedures required for the study, as judged by the investigator 5. Willing and able to provide written informed consent
Exclusion criteria
* Failure to obtain consent * Patients with liver cirrhosis * Any co-morbid condition with expected survival \< 1 year * History of extensive bowel resection, multiple abdominal surgeries * Women who are pregnant, breastfeeding, or of childbearing potential and not willing to use methods of birth control * Uncontrolled diabetes * Patients currently receiving total parenteral nutrition (TPN) * Recipients of an organ transplant * Patients who have consumed \>20cc of alcohol or have taken acetaminophen in the past 24 hours * History of chronic obstructive pulmonary disease or symptomatic bronchial asthma * Patients taking drugs that can interfere with 13C di-peptide metabolization
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To assess the pancreatic exocrine insufficiency using a 13C labeled di-peptide breath tests in patients with chronic pancreatitis(CP) and show correlation with secretin stimulated endoscopic Pancreatic Function Test (ePFT). | 1 hour | This breath test substrate is new and is hypothesized, based on preliminary studies, that it may be the answer to a much needed non-invasive pancreatic function test. At first stage, it will be compared to the current invasive gold standard: secretin induced ePFT. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To assess the ability to differentiate between non patients with chronic pancreatitis and those without. | 1 hour | In order to establish the efficacy of this test, it is necessary to confirm that a difference is observed between healthy and non- healthy subjects |
