Impact of Rheumatoid Arthritis on Body Composition, Bone Marrow Adiposity and Bone Mineral Density: a Case-control Study
- Conditions
- Rheumatoid Arthritis
- Registration Number
- NCT05269069
- Lead Sponsor
- University Hospital, Lille
- Brief Summary
During rheumatoid arthritis (RA) (in comparison with control subjects), body composition is altered with a loss of lean body mass, bone mass and an accumulation of fat mass.
Determination of total body fat and particularly its abdominal distribution (visceral adiposity) is important because of the cardiovascular (excess cardiovascular risk), metabolic (insulin resistance, diabetes and dyslipidemia) and bone (increased fracture risk) risks associated with this endocrine organ. Moreover, we do not have data concerning medullary adiposity in RA.
This pilot case-control study will be compare body composition, bone marrow adiposity and bone mineral density in patients with RA versus healthy volunteers.
