Alterations in cardiovascular autonomic function tests in idiopathic hyperhidrosis.
Auton Neurosci. 2012 Apr 03; 167(1-2):34-8.AN

Abstract

We performed cardiovascular autonomic function tests to assess sympathetic and parasympathetic functions in patients with idiopathic hyperhidrosis. We studied 35 patients with idiopathic hyperhidrosis and 35 age- and sex-matched controls. A thermoregulatory sweat test (TST) was performed in all subjects. Sweating was qualitatively (Minor's test at 22°C) and quantitatively (skin conductance) evaluated. Orthostatism, tilt to 65°, cold pressor test, deep breathing, Valsalva maneuver and hyperventilation were performed in patients and controls. A greater fall in blood pressure values was observed in patients than in controls in the upright tests (p<0.05). In particular, postural hypotension was present in a subgroup of patients (34%), in whom changes in lying-to-standing blood pressure and heart rate were greater (p<0.001) than those of the remaining patients. The TST revealed that the total body sweat rate (ml/cm(2)/min) was more pronounced in patients with postural hypotension (p<0.001) than in the other patients and controls. The skin conductance values of patients with postural hypotension were higher (p<0.001) than those of the remaining patients. A positive correlation was found between skin conductance values and postural hypotension. Dehydration and poor water intake may play a role in postural hypotension in patients with severe hyperhidrosis and pronounced thermoregulatory sweating. A significantly marked increase in parasympathetic function was observed in patients. Responses to deep breathing, Valsalva maneuver and hyperventilation were significantly greater in patients (p<0.001) than in controls. Idiopathic hyperhidrosis seems to be a complex dysfunction that involves autonomic pathways other than those related to sweating.
