The aim of this study was to assess of bone mineral content (BMC) and bone mineral density (BMD) of the forearm using DXA technique (DTX-200) and to evaluate broadband ultrasound attenuation (BUA) and speed of sound (SOS) of the heel using QUS technique (DTU-ONE). We examined 83 RA patients: 73 women and 10 men, at average age (55.0 +/- 12.2 yrs), ranging from 29 to 85 yrs. Average disease duration was 112.6 +/- 98.1 months. Disease activity was assessed according to Mallya and Mace index and radiological stage of the disease according to Steinbrocker index. We found significant correlation between BMC, BMD and BUA (r = 0.6572, r = 0.6081, respectively) and between BMC, BMD and SOS (r = 0.4704, r = 0.4723, respectively).
In Conclusion:
quantitative ultrasound parameters (BUA and SOS) significant correlate with BMC and BMD values of the forearm assessed by DXA technique in rheumatoid arthritis patients.
