GastroBiom

Gastronintestinal Biomarkers for Optimal Management

The project aims to develop and validate biomarkers for diagnosis and treatment evaluation of gastroenterological diseases, including functional, inflammatory and infectious conditions– including tests for malabsorption (e.g., 13C-isotope-based breath tests), gut inflammation (e.g., fecal calprotectin) and microbiota metabolism (e.g., fecal short-chain fatty acids). 

Since the opening of Unger-Vetlesen Institute in 2011, the project has resulted in 10 completed PhD theses, and more than 400 publications (see below for details). The project strive to inspire and motivate aspiring and established health care workers to perform research and accordingly enable the hospital to reap the benefits of the ripple effects that this creates. The titles of the completed PhD theses gives an overview of the topics that have been covered over the years. Ongoing and future studies include establishing a 13C-based sucrose breath test for clinical use, explore a panel of biomarkers for fibrosis to predict the disease course of Crohn`s disease, and explore the use of a novel wireless motility capsule as an actionable biomarker in neurogastroenterological disorders and diseases.
