Type 1 Diabetes Mellitus Clinical Trial
Official title:
Assessment of Endothelial Dysfunction in Retinal and Peripheral Retinal Vessels in Diabetes
The aim of the study is to progress in the understanding of the early retinal vascular and neural abnormalities in patients with diabetes, using a new device, the Dynamic Vessel Analyzer. The Dynamic Vessel Analyzer allows to measure the diameter of the retinal vessels and to assess how it varies in presence of various stimuli. Then, we will be able to assess if a vascular and/or a neural dysfunction is present early in patient with diabetes.
Twenty patients with type 1 diabetes without diabetic retinopathy and without arterial hypertension will be compared with 20 sex and aged-matched healthy control subjects. To assess the presence of retinal endothelial dysfunction, the variations of the diameters of the retinal vessels will be assessed using the Dynamic Vessel Analyzer, before and after flicker light stimulation, sublingual nitroglycerin, neosynephrine eyedrops, and isometric contraction. To assess the presence of peripheral endothelial dysfunction, the microcirculation of the forearm skin will be studied using iontophoresis with acetylcholine delivery, and heat delivery, both coupled with blood flow measurement using laser Doppler. An intravital capillaroscopy of the phalanx skin will be performed. The serum levels of CRP, ICAM-1, VCAM-1, VEGF, angiopoietin 2 and endostatin will also be measured. ;
