What this trial studies

This pilot study aims to evaluate the effects of intravenous oxytocin on chronic pain in female adult patients diagnosed with hypermobile Ehlers-Danlos syndrome (hEDS). The study will be conducted at a single site and will include two treatment periods: one with oxytocin and one with a placebo, with a one-month washout period in between. Participants will be blinded to the treatment order and will undergo daily pain evaluations using a questionnaire during each treatment phase. The study also includes assessments for anxiety and depression, and participants will wear a device to monitor heart rate.

Who should consider this trial

Good fit: Ideal candidates are premenopausal females over 18 years old with a clinical diagnosis of hypermobile EDS and chronic moderate to severe pain.

Not a fit: Patients with known allergies to oxytocin, those who are pregnant or lactating, or those with certain autoimmune disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for managing chronic pain in women with hypermobile Ehlers-Danlos syndrome.

How similar studies have performed: While the use of oxytocin for pain management is an emerging area, this specific approach in hypermobile EDS is novel and has not been extensively tested in previous studies.
