Brief Summary:
Oxytocin (OT) is a hypothalamic peptide that enters the peripheral circulation via the posterior pituitary gland. OT plays a key role in regulating appetite, psychopathology, prosocial behavior and sexual function. Hypopituitarism is associated with increased obesity, increased psychopathology, sexual and prosocial dysfunction despite appropriate hormone replacement. A few studies suggest the existence of a possible OT deficient state in hypopituitarism. In animal models, glucagon-like peptide 1 (GLP1) has shown to increase OT release.
This study is designed to evaluate OT values after administration of GLP1 in adults (healthy volunteers and patients with hypopituitarism).
The investigators hypothesize that OT response will be blunted following GLP1 receptor agonist (GLP1-RA) in patients with hypopituitarism compared to healthy controls.
Detailed Description:
This research is focused on two groups of participants: healthy controls (HC) and hypopituitary patients (HYPO) with at least one symptom of hypothalamic damage, presumably at highest risk for OT deficiency.
The aim is to improve knowledge on the physiology and patho-physiology of endogenous OT secretion in hypopituitary patients compared to healthy controls using a randomized, single-blind, crossover assignment (GLP1-RA vs placebo), placebo-control design.
Clinical implications of secretory OT dynamics and release under different stimuli using validated questionnaires to evaluate psychopathology, socio-emotional functioning, disordered eating behavior, impaired quality of life and sexual dysfunction, will be also evaluated.
