THE MALABSORPTION BLOOD TEST TRIAL WILL HELP DETERMINE THE BENEFITS OF PANCREATIC ENZYME REPLACEMENT THERAPY IN PATIENTS WITH MILD TO MODERATE EXOCRINE PANCREATIC INSUFFICIENCY.

This project uses the Malabsorption Blood Test (MBT) to identify patients with recurrent acute or chronic pancreatitis who have mild to moderate exocrine pancreatic insufficiency. A subgroup of patients who have response to pancreatic enzyme replacement therapy will enter a randomized, placebo-controlled pilot clinical trial for 8 weeks to identify improvements in quality of life (QOL).

A Study Of Effect Of Secretin For In Injection (Chirostim) On Pancreatic Fluid Composition In Healthy Subjects

The purpose of this study is to collect pancreas fluid from the duodenum using the endoscopic pancreas function collection method in healthy participants after pancreatic stimulation with human secretin.

Evaluating the Utility of RELiZORB™ for Treating Feeding Intolerance in Critically Ill Adults With Multi-Organ Failure

The purpose of this research is to determine if the use of RELiZORB™ improves nutrition tolerance and helps critically ill patients meet their nutrition goals. RELiZORB™ is a digestive enzyme cartridge that contains lipase and works as a pancreatic enzyme replacement. It promotes breaking down fat and helps the body absorb it. The device connects with tube feedings to help the body with digestion. RELiZORB™ is approved by the U.S. Food and Drug Administration (FDA) for use with tube feedings in patients 5 years of age or older. While the use of RELiZORB™ in this study is consistent with the FDA approval, the use of RELiZORB™ in patients with multi organ failure is not in the current standard of care practice at Inova Health Care facilities.

Pancreatic Enzyme Replacement Therapy for Acute Pancreatitis-Associated Exocrine Pancreatic Insufficiency

This study aims to evaluate if a 6-month course of pancrelipase (CREON) treatment improves symptoms of exocrine pancreatic insufficiency (EPI) after an attack of acute pancreatitis. Diagnosis of EPI is measured by a fecal elastase value of \<200, and patients must have a qualifying symptom burden based on the EPI symptom tracker survey. Blood and stool will be analyzed as part of this study, and other surveys of health status will be used to track improvement of symptoms.

Exocrine Pancreatic Insufficiency and Functional Dyspepsia

The goal of this observational study is to learn about the prevalence of exocrine pancreatic insufficiency in patients with functional dyspepsia . . The main questions it aims to answer are: What is the prevalence of exocrine pancreatic insufficiency (EPI) in patients with functional dyspepsia? Wich are the clinical characteristics associated with (EPI) in patients with functional dyspepsia? Patients diagnosed with functional dyspepsia will undergo an evaluation of clinical symptoms and fecal elastase determination. In those with fecal elastase levels below 100 µg/g, an endoscopic ultrasound and other assessments will be performed to define the cause of exocrine pancreatic insufficiency (EPI).

Fatty Liver and Pancreatic Steatosis

The goal of this observational study is to determine the prevalence of pancreatic steatosis in patients with fatty liver and determine the prevalence of exocrine pancreatic insufficiency (EPI) in these patients. Participants with fatty liver and metabolic syndrome will undergo fecal elastase measurement and endoscopic ultrasound (EUS).

Shwachman-Diamond Syndrome Global Patient Survey and Partnering Platform

The Shwachman-Diamond Syndrome Global Patient Survey and Collaboration Program (SDS-GPS) is an opportunity for patients and their families - from anywhere in the world - to share their experience living with SDS via a safe, secure, and convenient online platform, to * expand the understanding of SDS * improve the lives of people with SDS, and * accelerate the development of new therapies and cures for SDS. By joining, participants will receive early access to relevant information about new clinical trials and other research opportunities (such as clinical registries) based on their profile, accelerating research and increasing clinical trial impact and recruitment success. The platform, consent forms, and surveys are available in five languages: English, Spanish, French, German, and Italian. More languages to come.

Investigating Predictive Factors of Diabetes Occurence After Duodenalpancreatectomy

Regeneration of mature cells that produce functional insulin represents a major focus of current diabetes research aimed at restoring beta cell mass in patients with most forms of diabetes. The capacity to adapt in response to diverse physiological conditions during life and the consequent ability to cope for increased metabolic demands is a distinctive feature of the endocrine pancreas in the regulation of glucose homeostasis. Both beta and alpha cells are dynamically regulated to continually maintain a balance between proliferation, neogenesis, and apoptosis. In this proposal, the investigators will focus on exploring key mechanism(s) that potentially regulate islet cell plasticity in altered glucose metabolic states. Investigators will explore in a unique cohort of individuals who undergo duodenal pancretectomy. Prior to their surgery will be performed in vivo studies (Hyperglycemic clamp, Euglycemic Hyperinsulinemic clamp and Mixed Meal Tests) to accurately assess glucose homeostasis parameters to classify each individual into metabolic phenotypes. Then exploit the opportunity to collect pancreas samples from these patients who will be evaluated again after surgery, the investigators will determine the ability of the remnant pancreas to compensate for the acute reduction in islet mass and perform correlations between ex vivo and in vivo parameters. Specifically, the patients will be subjected to incretin secretion (mixed meal), metabolic status (OGTT), insulin secretion characteristics (first and second phase responses), β-cell insulin content evaluation (arginine bolus). Subsequently, pancreas samples will be evaluated for morphometry, and proteomics and gene expression analyses of islet cell samples obtain by laser capture will allow a detailed investigation of mechanisms that contribute to islet plasticity. The overall goal of this project is to investigate key mechanisms driving the ability of islet mass to adapt to diverse metabolic states. We aim to explore modifications in gene expression and proteomics and correlate them with specific metabolic phenotypes, in order to determine key regulators of islet morphology.

The Effects of Pancreatic Enzyme Supplementation in Critically Ill Patients on Enteral Feeding

Determine the effect of high-dose pancreatic enzyme supplementation on nutritional indicators and clinical course in critically ill patients undergoing enteral nutrition.
