Avascular Bone Necrosis in Sickle Cell Disease: a Pediatric Study.

Avascular necrosis (AVN) is a serious complication of sickle cell disease, especially in pediatric patients where the prevalence is between 3% and 8% and are more frequent in patients with multiple vaso-occlusive crisis (VOC). The prevalence of AVN is usually made by a study of the hip through radiography, whereas other possible sites of ischemic infarcts are evaluated only in case of specific symptoms. In addition, bone infarcts may be the trigger for additional VOC.

In this study, we want to investigate the presence of possible bone lesions even in asymptomatic or paucisymptomatic children.

This is a prospective interventional and monocentric study whose objective is to describe the prevalence of osteonecrosis in children with sickle cell disease in Italy

Female or male patients diagnosed with sickle cell anemia (HbSS, HbS/β0, HbS/β+, HbSC) with or without known avascular lesions
Age ≥ 7 and < 18 years at the moment of signed consent
Written informed consent/assent, according to local guidelines, signed by patient and/or guidelines, signed by the patient and/or at least one parent or legal guardian

Treatment and study plan

Primary outcomes

Calculate the prevalence of unknown osteonecrosis

Time frame: Day 1

Avascular necrosis of the bones are diagnosed by systematic MRI at sites: total spine, femurs, shoulders, humeri and total hip. These data will be collected in the patient's medical record in patients with sickle cell anemia regardless of the number and intensity of vaso-occlusive crisis
