Dr Liza Phillips (MBBS (Hons), FRACP, PhD, MS (Epi)), is a consultant endocrinologist and post-doctoral research fellow at the Royal Adelaide Hospital and a Clinical Lecturer at the University of Adelaide. She has clinical interests in diabetes, pituitary disease and inborn errors of metabolism in adults and is the deputy director of physician education at the Royal Adelaide Hospital. She is an early career researcher with an interest in the epidemiology and physiology of type 2 diabetes, in particular, the interaction between the gut and glycaemia and the impact of glycaemic control/diabetes in critical care.
Research Project 1
Title: Effects of acute and sub-acute treatment with metformin on cardiovascular responses to a glucose challenge in type 2 diabetes
Project description: Type 2 diabetes (T2DM) is associated with a two-fold increased risk of cardiovascular disease, and despite targeted lifestyle and pharmacologic strategies that modify risk factors, myocardial infarction remains the leading cause of death in this population.
Improvements in glycaemic control have only a modest effect to optimise cardiovascular outcomes in contrast to their profound effect to diminish the risk of development and progression of microvascular disease. Moreover, studies with metformin, an established first-line medication for T2DM, and more recently, agents from the sodium glucose linked transporter 2 (SGLT-2) inhibitor and glucagon-like peptide-1 (GLP-1) agonist classes, have highlighted the importance of ‘non-glycaemia’ driven mechanisms, translating into impressive reductions in cardiovascular disease in T2DM.
Postprandial hyperglycaemia is an independent cardiovascular risk factor, makes a major contribution to overall glycaemic control as determined by HbA1c and thus is an important therapeutic target. Our recent work has established that metformin, at least in the acute setting, modulates cardiovascular responses, including blood pressure (BP) and heart rate (HR), to enteral nutrients in patients with T2DM. In this study we will investigate the acute and sub-acute effects of metformin on the cardiovascular responses to a 75g glucose challenge in T2DM.
