Abstract

Type 1 diabetes (T1D) is characterized by a progressive decline of insulin production due to a marked destruction of pancreatic B cells. Intensive insulin therapy is the pillar of T1D management. More recently, continuous glucose monitoring devices, closed-loop systems (CLS) and smarter connected insulin pen systems have all significantly helped individuals to improve glycemic control. Despite these advances, however, more than three-quarters of the adult T1D population does not achieve recommended glycemic targets. In addition, aggressive insulin intensification potentiates weight gain and the risk of recurrent hypoglycemic events. Recent significant increase in rates of obesity has also led to a sharp increase in T1D patients who concurrently have adiposity-based chronic disease, increasing their insulin resistance and predisposition for cardiovascular events. While insulin will remain the basis of T1D management, there is an unmet need for individualized adjunctive therapeutic approaches focusing on the prevention of diabetic complications in addition to glycemic control. One such adjunctive therapy currently being explored in T1D are the glucagon-like peptide-1 receptor agonists (GLP-1 RAs), a popular and robust approach in Type 2 diabetes (T2DM) to mimic the natural endogenous GLP-1 incretin. This brief review will focus on the rationale and existing evidence for the use of GLP-1 RAs in the management of T1D.

Author Biography

Michael A. Tsoukas, MD, FRCPC, Division of Endocrinology, McGill University Health Centre

Dr. Michael Tsoukas is an Associate Professor of Medicine, Division of Endocrinology at the McGill University Health Centre and Clinician Investigator of the Research Institute of McGill and Hygea Medical Clinic. He completed his residency training at Tuft’s University and subsequently trained in Endocrinology at McGill University. He later pursued a post-graduate research fellowship in diabetes and obesity at Harvard University (Beth Israel Deaconess Medical Center), with a focus on GLP-1 receptor pharmacotherapy, brain signaling, and enterohormone treatments. Further training involved pathophysiological regulation of novel molecules such as SGLT-2 inhibitors and GLP-1 receptor agonists important in energy homeostasis, diabetes, and obesity.

Dr. Tsoukas continues to conduct clinical interventional studies in humans, ranging from pre-clinical pharmacokinetic studies to large-scale placebo-controlled clinical trials. He has authored over 40 articles in peer-reviewed journals, chapters, and abstracts. He has recently been selected as an Executive Member of the Professional Section for Diabetes Canada. Concurrently, he is also involved in training future generations as the site Director for Endocrinology at the Montreal General Hospital.
