Clinical Trial Summary

This study is to evaluate oxytocin levels in response to MDMA administration as compared to placebo in patients with diabetes insipidus and healthy volunteers.

Description:

Disruption of the hypothalamic-pituitary axis due to congenital abnormalities, tumors or head trauma may cause anterior and/or posterior pituitary deficiency also known as partial or panhypopituitarism. Patients with hypopituitarism, especially those with panhypopituitarism (i.e., anterior and posterior insufficiency) often report residual symptoms and lower quality of life despite adequate substitution treatment of deficient pituitary hormones. A recent study identified a potential oxytocin deficient state in men with combined anterior and posterior deficiency. Due to the close proximity of vasopressin and oxytocin, disruption of the vasopressin system leading to diabetes insipidus could as well disturb the oxytocin system leading to low oxytocin levels. It is therefore possible that the increased psychopathology and reduced quality of life as observed in patients with central diabetes insipidus is caused by an oxytocin deficiency. Several studies documented marked acute increases in circulating oxytocin levels in response to 3,4-methylenedioxymethamphetamine (MDMA) administration as compared to placebo in healthy volunteers. MDMA could therefore be useful as a provocation test to detect an oxytocin deficiency in patients with central diabetes insipidus. This study is to investigate if oxytocin provocation following a single dose administration of MDMA is reduced in patients with central diabetes insipidus as compared to healthy volunteers.

Intervention

Diagnostic Test:
• study intervention: 3,4-methylenedioxymethamphetamine (MDMA, ecstasy)
single administration of MDMA (100mg): 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) will be prepared as gelatin capsules with mannitol as the filler. MDMA will be administered in a single absolute dose of 100 mg corresponding to a medium high dose of (mean ± SD) 1.3 ± 0.3 mg/kg body weight.
• Control intervention: Placebo
Identical placebo (only mannitol) capsules
