After 1 2 and 5 years large BMD losses were found and respectively. Elevated erythrocyte sedimentation rate and anti-cyclic citrullinated peptide levels were independent predictors of bone loss indicating that the largest amount of bone loss was found in patients with severe inflammation and high production of auto-antibodies who are known to be at the highest risk of developing radiological bone damage. Studies are needed about the spatial and time relationship between erosions and juxta-articular and metacarpal bone loss. The elegant study by Boyesen and colleagues 1 in the previous issue of Arthritis Research Therapy in which they observed the changes in hand bone mineral density BMD using digital x-ray radiogrammetry DXR in 163 patients with early rheumatoid arthritis RA is most welcome. DXR measures the cortical thickness width and porosity of the central parts of metacarpals 2 to 4. After 1 2 and 5 years of observation .
