Trabecular but not cortical bone mass was significantly correlated to eosinophil counts and ECP levels in RA patients without glucocorticoids (r = 0.71, p = 0.0001; r = 0.55, p = 0.0039) and in healthy controls (r = 0.57, p = 0.0025; r = 0.57, p = 0.0027). This evidence concerns the gene RNASE3 and rheumatoid arthritis.
