Biography of Bertus Eksteen

Bertus Eksteen’s path to medicine was driven by an innate curiosity about how the human body combats disease. Born and raised in South Africa, he completed his MBChB at the University of Pretoria in 1996. This began a medical career fueled by a passion for understanding complex diseases His drive to expand his knowledge led him to further his studies internationally In 1998, he earned his membership in the Royal College of Physicians (MRCP) in London and then completed a PhD in immunology at the University of Birmingham
Following his academic training, Bertus pursued a Certificate of Completion of Training (CCT) in Gastroenterology and Hepatology in 2008, which allowed him to develop deep expertise in these areas In late 2011, he earned a Fellowship (FRCP) with the Royal College of Physicians This combination of clinical knowledge and research training laid a solid foundation for a career dedicated to improving healthcare for patients with chronic, complex conditions, particularly those related to the liver
Building a Global Reputation in Calgary
Currently, Eksteen resides in Calgary, Alberta, where he leads a liver research program at the Aspen Woods Clinic Under his leadership, the clinic has become internationally recognized as one of the largest centers for conducting clinical trials on Primary Sclerosing Cholangitis (PSC) and Inflammatory Bowel Disease (IBD). The clinic serves patients from Southern Alberta, eastern British Columbia, and western Saskatchewan, and it works closely with several biotech companies to develop novel therapies for PSC
In addition to his work at Aspen Woods Clinic, Bertus plays an active role at the Southern Alberta Liver Transplant Clinic at the Foothills Hospital in Calgary. He is also a Clinical Associate Professor of Medicine at the University of Calgary, where he is dedicated to educating and mentoring the next generation of gastroenterologists and hepatologists His efforts ensure that students and young professionals are well-equipped to handle the challenges of treating complex diseases, perpetuating a legacy of knowledge and expertise in the field
Turning Science into Solutions
Eksteen’s scientific contributions have been groundbreaking, particularly in understanding autoimmune diseases that affect the liver. One of his early discoveries was related to how mucosal T-cells behave abnormally in diseases such as PSC and IBD His research demonstrated that these immune cells attack the liver, altering how the scientific community views autoimmune liver diseases. This discovery has provided valuable insights that have transformed therapeutic approaches for these conditions
Bertus also worked to establish a cohort of over 400 PSC patients, leading to the identification and publication of nine new genetic risk loci for PSC His collaboration with the International PSC Study Group was pivotal in this achievement. His research efforts have been supported by significant funding from the Medical Research Council in the UK and Canada He was the national co-lead Principal Investigator for the Canadian Institutes for Health Research (CIHR) SPOR program, which focused on investigating the role of the gut microbiome in IBD.
As a Principal Investigator for another CIHR Signature Initiative, Bertus has contributed to advancing research on chronic inflammatory diseases His work has also led to improvements in clinical endoscopic imaging, allowing for the early detection of dysplasia in patients with PSC and IBD. These advancements have revolutionized how doctors detect and manage pre-cancerous changes in these diseases, significantly improving patient care and outcomes
