Enhanced cholinergic and dopaminergic controls of anterior pituitary function have been described in insulin-dependent diabetes mellitus (IDDM). In order to verify whether similar neurotransmitter alterations also affect the regulation of posterior pituitary hormone secretion, the arginine-vasopressin (AVP) responses to the dopaminergic agonist apomorphine and in a different occasion to physostigmine, an acetylcholinesterase inhibitor, were evaluated in normal (n = 10) and type I diabetics (n = 16). In addition, a control test with normal saline was performed in all subjects. None of the diabetic patients were affected by neuropathy or other diabetic complications. They were divided into two groups according to the duration of their disease (less than 10 years: group 1, n = 8; more than 10 years: group 2, n = 8). Physostigmine (12.5 micrograms kg-1) was infused intravenously over 10 min; apomorphine (60 micrograms kg-1) was injected subcutaneously. Basal AVP concentrations were similar in all groups and remained constant during the control test. In contrast, both drugs induced significant increments in plasma AVP levels in the normal controls and diabetic subjects. However, physostigmine- and apomorphine-induced AVP increments were twofold higher in diabetics than in control subjects. No significant differences were observed between diabetics of groups 1 and 2. No significant correlations between duration of diabetes and peak AVP responses to physostigmine or apomorphine were found within each group or when all diabetic subjects were considered together. These data indicate enhancement of both dopaminergic and cholinergic stimulatory regulations of AVP secretion in patients with uncomplicated IDDM, regardless of the duration of diabetes.
