Low bone mass and hypovitaminosis D in haemophilia: A single‐centre study in patients with severe and moderate haemophilia A and B

Introduction Haemophilia (H) is frequently associated with a multifactorial reduction in bone mineral density (BDM), but little is known about possible differences between HA and HB according to their severity. Aim To evaluate the association between low bone mineral density (BMD), 25‐hydroxyvitamin D [25(OH)D] concentrations and bone turnover markers in patients with HA and HB younger or older than 50 years. Methods In 78 patients <50 years...
