Calcium-phosphate Complications Induced by IV Iron Supplementation in Patients With Rendu-Osler Disease

Overview

Hypophosphatemia induced by treatments with injectable iron is a frequent side effect already reported during marketing. Situations of osteomalacia secondary to these hypophosphatemias are rarer and reported in the form of case reports in the literature. Hypophosphatemia in this context is attributed to an excess of FGF-23 (defect of degradation linked to carbohydrates in martial preparations) with renal leakage of phosphate. Rendu-Osler disease (ROM) is an autosomal dominant genetic disease, favoring the formation of vascular malformations, including nasal and digestive telangiectasias causing repeated bleeding, even hemorrhages. Iron deficiency is frequent and profound there, and oral martial treatments are often insufficient to compensate for these losses. Regular iron infusions, to avoid transfusions, are often necessary.
