Research Interest
Dr. Papachristou’s research interests center on acute pancreatitis. Dr. Papachristou leads a number of institutional studies and multi-center collaborations. He is the principal investigator in the Post-Acute Pancreatitis Pancreatic Exocrine Insufficiency (PAPPEI) trial, a prospective, multicenter study, which evaluates the incidence of exocrine pancreatic insufficiency and long-term quality of life in subjects after an attack of acute pancreatitis. Dr. Papachristou is also the site principal investigator for a multicenter randomized trial entitled Stent versus Indomethacin (SVI), which compares different preventive treatments for post-ERCP acute pancreatitis. He also leads APPRENTICE (Acute Pancreatitis Patient Registry To Examine Novel Therapies In Clinical Experiences), an international consortium for acute pancreatitis care involving 22 centers throughout the world. Additionally, Dr. Papachristou directs a translational research laboratory focusing on the genetic basis, immunology, and inflammatory responses in acute pancreatitis. His current research funding is from the National Institute of Health, industry, and private donors. Dr. Papachristou has authored over 100 peer reviewed articles and book chapters.
