Brief Summary:

Sickle cell disease is the most common single-gene disease in the world. Its prevalence is increasing in France, with patients' life expectancy increasing into developed countries. It mainly affects populations originating from sub-Saharan Africa. Among the chronic bone complications associated with sickle cell disease, osteoporosis has previously been highlighted but remains a poorly known complication in this very particular context. A dedicated evaluation of osteoporosis and associated risk factors in sickle cell disease patients living in France may enable better bone management of these patients in the future, as this problem, specific to their disease, is likely to become more frequent as their life expectancy increases.

This is a prospective interventional and monocentric study whose objective is to describe the prevalence of osteoporosis in black patients with sickle cell disease in France

Group/Cohort Intervention/treatment
sickle cell disease patients
150 black patients with sickle cell disease living in France, 20 to 40 years old will be included in this study
 Other: Questionnaire
For each subject recruited, will be collected for the study a questionnaire looking for a history of low energy fracture, and the origins of the patient (or relatives), as well as medical history, lifestyle (alcohol and tobacco consumption), weight and height. This data will be used for the secondary outcomes.


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Bone mineral density [ Time Frame: Day 1 ]
    Bone mineral density is measured by systematic bone densitometry at 3 sites: lumbar spine, femoral neck and total hip. These data will be collected in the patient's medical record
