[Vascular reactivity related to postural changes in diabetics].
Resting skin flow (RF) and the venoarteriolar response (VAR) were studied in 40 patients with diabetic microangiopathy and neuropathy, in 40 diabetes with microangiopathy and in 30 normal subjects using laser-Doppler flowmetry. In patients with microangiopathy and neuropathy RF was increased and the VAR was impaired to a greater extent than in patients without neuropathy. We evaluated the microangiopathy index (VAR/RF) that was lower in diabetics without neuropathy and even lower in those with neuropathy than in normals We also evaluated the VAR with different postural changes.
