Investigating complications from IV iron in patients with Rendu-Osler disease

Study of Calcium-phosphate Complications Induced by the Administration of IV Iron Supplementation in Patients With Rendu-Osler Disease

Observational University Hospital, Strasbourg, France · NCT05544669

This study looks at the problems that might happen when people with Rendu-Osler disease get IV iron, especially focusing on low phosphate levels and bone health.

What this trial studies

This observational study examines the complications associated with intravenous iron supplementation in patients suffering from Rendu-Osler disease, particularly focusing on the occurrence of hypophosphatemia and its potential link to osteomalacia. The study aims to gather data on how these complications arise, especially in relation to the excess of FGF-23 and renal phosphate leakage. By analyzing the experiences of patients receiving IV iron, the study seeks to enhance understanding of the risks involved in their treatment.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older diagnosed with Rendu-Osler disease who are currently receiving intravenous iron supplementation.

Not a fit: Patients who are not receiving IV iron supplementation or those who have expressed opposition to participating in the study may not benefit.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients with Rendu-Osler disease receiving IV iron, minimizing complications.

How similar studies have performed: While there have been case reports regarding hypophosphatemia and osteomalacia in similar contexts, this specific observational approach appears to be novel.
