Theodore M. Bayless, Professor of Medicine and Director Emeritus of the Meyerhoff Inflammatory Bowel Disease Center at Johns Hopkins is the first Sherlock Hibbs Professor in Inflammatory Bowel Disease. A clinician, researcher and an educator, Dr. Bayless has been a member of faculty at Johns Hopkins since 1964 and has provided patient care for over 4000 patients with IBD.
Dr. Bayless received his undergraduate training at the University of Pennsylvania and at Bucknell University; his M.D. degree at Chicago Medical School; Internal Medicine training at the Cornell Division of Bellevue Hospital and Memorial Sloan-Kettering Cancer Center, New York; and Gastroenterology research training, with a focus on celiac disease, at the Johns Hopkins Hospital.
He was awarded the Franklin Institute Medal for his work showing that lactase activity was under genetic control and tested lactose hydrolyzed milk. Dr. Bayless co-authored 145 peer-reviewed research papers and was elected to the American Society for Clinical Investigation in 1975. In 1987, he received the first Distinguished Educator Award from the American Gastroenterological Association (AGA). In 2004, he received the Excellence in Teaching Award from the Johns Hopkins Alumni Association and he was again awarded by the AGA with a Distinguished Clinician Award.
As Director of the Meyerhoff Inflammatory Bowel Disease Center at Johns Hopkins he showed that within families with Crohn’s disease, the presentation of the illness was similar among multiple family members suggesting that there are separate types of Crohn’s disease. He and Dr. Steven R. Brant started the Meyerhoff IBD Family Study which showed that the strongest genetic linkage was in families with youthful onset and severe disease; and, most importantly, they collaborated on the first report of NOD2/CARD15 as a susceptibility gene in Crohn’s disease (Nature May, 2001). Patients with this gene change, as predicted by Dr. Bayless, show this type of youthful onset and complicated ileal disease. [Over 300 papers on NOD2/CARD15 have appeared since 2001]
Dr. Bayless served as Director of the AGA section on Immunology, Microbiology and Inflammatory Disorders and as National Chairman of the Crohn’s Colitis Foundation. Dr. Bayless, an active clinician himself, has edited 13 books for practicing physicians and patients. He has a newly published book available on Amazon.com since November 2011 entitled "Advanced Therapy in Inflammatory Bowel Disease Vol III".
