title: Autonomic dysfunction and peripheral vasodilatory response in diabetes.
abstract: Twenty three diabetes mellitus patients were investigated for peripheral vasodilatory response in relation to degree of autonomic dysfunction. The non-insulin dependent diabetes mellitus (NIDDM) patients had significant degree of autonomic dysfunction. Based on standard scoring system for evaluating autonomic dysfunction, diabetics were divided into 'borderline' (n = 12) and 'severe' (n = 11) diabetic autonomic neuropathy (DAN) groups. The severe DAN patients showed significantly lower pressor response when compared to borderline DAN patients. Severe DAN was also associated with significant peripheral vascular dysfunction. The severe DAN patients largely had no clinical manifestation of peripheral vascular dysfunction. Thus, at subclinical level patients with significant autonomic dysfunction do exhibit peripheral vascular dysfunction.
