Research summary
Stroke is the biggest cause of disability in the Western World, however treatments to reduce the immediate effects of stroke have met with limited success. Glucagon-like peptide-1 (GLP-1) is produced by the gut in response to gastric stimulation. It is partly responsible for stimulating the production of insulin to help deal with the sugar in a meal, but it also regulates the blood vessels of the heart, muscles and brain by acting on specific receptors. In animal models, artificially increasing levels of GLP-1 reduces the size of a stroke even when it is given after the stroke. In humans, however, this has never been tried, indeed after a serious stroke, because of weakness of the face and throat, patients are often put ??Nil by Mouth?Â, to protect the airway, meaning they do not receive any food oflud by mouth. This will actually decrease the levels of naturally occurring GLP-1. We plan to give a synthetic form of GLP-1 (Liraglutide) that is already available and licensed for use in patients with diabetes in the UK, to patients who have had an acute stroke and are put ??nil by mouth?Â, in order to determine whether increased levels protect the brain during its recovery, resulting in better recovery. As this form of GLP-1 is given by injection we will easily be able to give it to patients who have had a Stroke even if they have weakness of the face or throat. In the first instance, we will do this on a small number of participants (20 being treated with the active agent, 20 with standard care) to ensure the feasibility and safety of such a study. We will administer the drug as soon as possible after the stroke and for the subsequent 6 days. At the end of this period we will reassess participants in order to record their recovery (Using NIHSS scale) at day 7 and day 30, and we will perform a MRI scan (magnetic resonance imaging) that will measure the amount of damage to the brain left after the stroke. We will also assess microvascular function on day 1 of the treatment and repeat it on day 7 to determine the effect of Liraglutide on microvascular function and whether this have a detrimental effect on recovery from stroke.
