Renal impairment of pure autonomic failure.

Vascular endothelial function and blood pressure regulation in afferent autonomic failure.

BACKGROUND Familial dysautonomia (FD) is a rare hereditary disease characterized by loss of afferent autonomic neural fiber signaling and consequent profound impairment of arterial baroreflex function and blood pressure regulation. Whether vascular endothelial dysfunction contributes to defective vasomotor control in this form of afferent autonomic failure is not known. METHODS We assessed bl...

Comment on Cisplatin-Induced Renal Impairment

[Autoimmune autonomic ganglionopathy and acute autonomic and sensory neuropathy].

Autonomic neuropathies may occur primarily or secondarily to various underlying diseases. Primary autonomic neuropathies are divided into pure autonomic neuropathy, autonomic neuropathy with sensory impairment, and autonomic neuropathy with sensory and motor impairment based on the concomitance or absence of sensory or motor dysfunctions. Autoimmune autonomic ganglionopathy refers to a pure aut...

Kidney Renal Impairment of Pure Autonomic Failure

Supine hypertension is difficult to manage in patients with pure autonomic failure (PAF), because treatment can worsen orthostatic hypotension. Supine hypertension in PAF has been associated with left ventricular hypertrophy, but end organ damage in the kidney has not been assessed. We reviewed hemodynamic and laboratory data of 64 male patients with PAF who were 69 11 (mean SD) years old. Syst...

Spectrum of autonomic cardiovascular neuropathy in diabetes.

OBJECTIVE Diabetic patients with incapacitating orthostatic hypotension can have either a "hyperadrenergic" or "hypoadrenergic" presentation. Although the latter is related to overt autonomic neuropathy, the former is proposed to be explained by appropriate autonomic responses. We hypothesize, however, that both conditions are part of a spectrum of autonomic dysfunction. RESEARCH DESIGN AND M...
