Wysham and fellow researchers from UC San Francisco, who looked at patients with rheumatoid arthritis (RA), found a positive relationship between appendicular lean mass index (ALMI) and bone mineral density (BMD) and a negative relationship between anti–cyclic citrullinated peptide (anti-CCP) and BMD.1
Scroll through the slides for the details of the study and the take-home messages for clinicians.
Multivariate analysis was used to determine associations between the variables.
ALMI, appendicular lean mass index; anti-CCP, anti–cyclic citrullinated peptide; DXA, dual-energy x-ray absorptiometry; FMI, fat mass index; RF, rheumatoid factor.
Men had higher rates of obesity as defined by DXA total fat (80% of men were obese versus 44% of women; P < .0001) and higher rates of self-reported low physical activity (43% for men versus 27% for women; P = .050). Oral steroid dose had negative associations with BMD (P < 0.1, except RF P < .05).
A simple blood test can help physicians assess patients with RA for fracture risk.
