  • Research summary

    Type 1 diabetes (T1D) is associated with vascular complications that increase mortality risk, underpinned by extensive vascular disease coupled with an enhanced thrombotic environment. We have found that individuals with T1D have lower plasma magnesium concentrations than in age/sex-matched controls and that these reduced levels associate with impaired fibrin clot lysis. Hypofibrinolysis predicts cardiovascular outcomes in diabetes and targeting this pathway has the potential to reduce thrombosis risk. We hypothesise that adequate plasma magnesium concentrations are important for normal haemostasis. We propose to examine the role(s) of magnesium in regulating fibrinolysis using in vitro/in vivo approaches and employing a clinical study of magnesium supplementation in deficient T1D individuals. We will analyse the effects of magnesium on thrombotic/fibrinolytic potential, glycaemic and insulin resistance measures as well as patient well-being. We also will determine whether magnesium deficiency (and subsequent supplementation) induces molecular
    changes in coagulation factors that may influence fibrinolysis. This work will provide a mechanistic understanding of how magnesium controls fibrinolysis and will determine the usefulness of monitoring plasma magnesium in T1D and correcting abnormally low levels. In turn, this may pave the way to new T1D management strategies that reduce the mortality risk using a safe and affordable supplementary therapy.
