Investigating hypercalcemia caused by paraffin oil injections
Official title: Hypercalcemia After Paraffin Oil Injection: Aetiology, Pathogenesis and Possible Treatment Options
Run by Copenhagen University Hospital, Rigshospitalet · NCT04292288 · Data updated 2026-11-12
This study is trying to understand the health risks of paraffin oil injections in young men, especially how they might cause high calcium levels in the blood.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are young men who have previously injected paraffin oil into their bodies.
✕Probably not a fit
Patients who are unable to walk or have incurable cancer may not benefit from this study.

What this trial studies
This observational study aims to understand the health risks associated with the injection of paraffin oil into skeletal muscles, particularly among young men seeking cosmetic enhancements. It will involve a large group of participants who have injected varying amounts of paraffin oil, focusing on identifying risk factors for developing hypercalcemia and exploring the underlying mechanisms of the condition. The study will also culture granuloma tissue from selected patients to investigate the production of activated vitamin D and parathyroid hormone-related peptide. The findings could provide insights into the pathogenesis of hypercalcemia linked to cosmetic procedures.
Why it matters
Potential benefit: If successful, this study could lead to better awareness and management of hypercalcemia in patients who have undergone paraffin oil injections.
How similar studies have gone: While there have been case reports on this issue, this study represents a novel approach to understanding the broader implications of paraffin oil injections and their health risks.
