Effect of Oxytocin on Emotion Recognition and Acute Psychosocial Stress in Patients with Central Diabetes Insipidus (Vasopressin Deficiency) and Healthy Controls
Zusammenfassung der Studie
Patients with central diabetes insipidus suffer from a deficiency of the anti-diuretic hormone vasopressin. Patients with such a vasopressin deficiency produce a large amount of urine and must compensate for this fluid loss with a high fluid intake. Desmopressin, a medication similar to vasopressin, can be used to treat this condition. Despite treatment with desmopressin, patients often report symptoms such as general anxiety, social withdrawal, depressed mood, and have a reduced quality of life. A recent study has shown that these patients not only lack the hormone vasopressin but also the hormone oxytocin. In the brain, oxytocin is produced in the same area as vasopressin and released from the pituitary gland. The hormone is involved in important positive psychosocial aspects such as building trust, closeness, and love, has anxiolytic effects, positively influences sensations such as relaxation, and increases empathy; thus, this hormone is also referred to as the love and cuddle hormone. The observed psychological changes in patients may therefore be partially explained by this additional deficiency of oxytocin. In this study, we investigate whether a single administration of the study drug oxytocin in patients leads to an improvement in emotion perception or reduced stress reaction to psychological stress.

Untersuchte Intervention
This study is a so-called crossover study, meaning that all participants in the study receive a placebo on two study days and oxytocin as a nasal spray on two study days. After the preliminary examination, a total of four study days take place: • On two of these study days, a computer test for emotion perception is conducted – once with placebo and once with oxytocin as a nasal spray. • On the other two study days, a test of the stress reaction is conducted – once with placebo and once with oxytocin as a nasal spray.
