Abstract

The arginine-8-vasopressin (AVP) responses to osmotic and histamine stimuli were evaluated in 21 patients with central diabetes insipidus (CDI) and compared to those of 10 healthy controls. Plasma AVP was measured by radioimmunoassay. Following the infusion of 2.5% saline, the AVP responses of CDI patients fell into two distinct groups: CDI I gave no response at all, while CDI II responded subnormally. Histamine increased the plasma AVP level significantly in healthy volunteers. Patients with CDI II gave subnormal AVP responses to histamine. The AVP reactions of the patients with CDI I fell into two subgroups: CDI I/A had undetectable plasma AVP, while histamine evoked AVP release in CDI I/B. Histamine trial did not lead to any change in plasma osmolality. The authors conclude that patients with CD II suffer from a partial CDI, while those with CDI I/A represent a complete form of the disease. The remainder (CDI I/B) presumably have an osmoreceptor failure. Osmotic and non-osmotic stimulation may provide a useful tool in the differential diagnosis of CDI.
