Identifying oxytocin deficiency in adults with pituitary disease

Characterizing Oxytocin Response to Oral Estrogen Administration in Adults With Arginine Vasopressin Deficiency

Early Phase 1 Interventional Massachusetts General Hospital · NCT06460948

This study is testing how a single dose of hormone therapy affects oxytocin levels in adults with a specific pituitary condition to see if it relates to their anxiety, depression, and overall quality of life compared to healthy individuals.

What this trial studies

This pilot study aims to evaluate the oxytocin response to a single dose of oral Estrogen-progestin in adults with arginine-vasopressin deficiency compared to healthy controls. It will measure salivary and blood oxytocin levels and assess their association with symptoms of anxiety, depression, and quality of life. The study hypothesizes that individuals with arginine-vasopressin deficiency will exhibit lower oxytocin responses and more severe psychological symptoms than healthy participants.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-65 with arginine-vasopressin deficiency who are on stable pituitary hormone replacement.

Not a fit: Patients with a history of significant cardiovascular or cancer-related conditions, or those who are pregnant or breastfeeding, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and treatment options for patients with pituitary disease and associated psychological conditions.

How similar studies have performed: While this approach is novel in its specific focus on oxytocin response in this patient population, similar studies have explored hormonal influences on psychological conditions with varying degrees of success.
