Outcome Measures

Primary Outcomes (2)

  • Effect of oxytocin compared to placebo in patients with AVP deficiency compared to healthy controls on recognition of facial emotions/body expression

    Differences between the placebo and oxytocin session will be assessed for each participant in correct recognition of facial emotions \& body expressions assessed with the EmBody (emotion from body expressions) /EmFace (emotion from facial expressions) task of 3 or more score points (score range: 20-80) The EmBody and EmFace subtasks comprise each of 42 stimuli showing body or facial expressions of angry, happy, or neutral affect (14 clips per emotion, half in front view and half in half-profile side view from the left). Stimuli last 1.5 seconds at 24 frames per second and are geometrically and optically standardized to prevent biases induced by ethnic cues (e.g., hair or skin tone) or clothing. Item order is pseudorandom to prevent sequence effects and was determined using the following constraints: the same emotion is shown no more than twice in a row; the same view per emotion is not shown consecutively (i.e., no angry-front, angry-front).

    up to 4 weeks

  • Effect of oxytocin compared to placebo in patients with AVP deficiency compared to healthy controls cortisol in response to acute stress

    Differences between the placebo and oxytocin session will be assessed for each participant in cortisol levels in response to acute psychosocial stress induced upon the TSST (Trier Social Stress Test) by 15% or more in the area under the cortisol response curve. Salivary cortisol will be measured (as a measure of unbound cortisol concentrations in plasma) before and upon the TSST. Blood cortisol will also be measured The TSST consists of an unprepared speech and mental arithmetic performed in front of an audience. Previous studies indicated that this stress protocol reliably induces a significant HPA (Hypothalamic-pituitary-adrenal)-axis activation, with 2- to 3-fold increases in free cortisol and subjective responses indicative of moderate stress in healthy individuals.

    up to 10 weeks

  • Subjective emotional response to acute stress

    up to 10 weeks

  • Heart rate (bpm)

EXPERIMENTAL

Part A will investigate the recognition of facial emotions \& body expressions in a cross-over design with a two-week wash-out period between both study visits. Part B will investigate the response of cortisol to acute psychosocial stress (TSST) with an eight-week wash-out period between both study visits. The order of group assignment is as follows: 1.

Interventions

Participants will be instructed on correctly applying the intranasal study medication and will self-administer a single dose of 24 IU oxytocin under the supervision of unblinded study personnel.
