Bone loss in patients with rheumatoid arthritis (RA) varies at different skeletal sites. The aim of the study was to evaluate whether bone mineral density (BMD) of the forearm is significantly different in patients with RA and controls and may correlate to BMD or other parameters of inflammation or bone resorption. We included 421 patients (357 women: mean age 58.

Osteoporosis occurs frequently in patients with AS and OPG represents a soluble decoy receptor that neutralizes receptor activator of nuclear factor-kB ligand (RANKL), an essential cytokine for osteoclast function.
Methods: Clinical data, radiographs of the spine, BMD of lumbar spine and the femur, biochemical markers of bone turnover, and serum levels of OPG were evaluated in 264 patients with AS (72% men) and 240 age-matched healthy controls (76% men).
Osteoporotic vertebral compression fractures (VCFs) are associated with a series of clinical consequences leading to increased morbidity and even mortality. Early diagnosis and therapeutic intervention is desirable in order to remobilise patients and prevent further bone loss. Not all fractures are, however, sufficiently treatable by conservative measures.
