To assess the bone mineral density (BMD) and the frequency of osteoporosis and clinical fractures in a large group of Spanish patients with psoriatic arthritis (PsA).


BMD was determined by DXA in all the patients who were willing to participate and had peripheral PsA regularly evaluated in a tertiary university hospital. All patients underwent a physical examination and general laboratory analysis. We gathered demographic and clinical variables related with BMD and risk of fractures. We also recorded the history of clinical low impact fractures. The population of reference to calculate T-score and Z-score came from a Spanish database.


One hundred and fifty-five patients were included (64 postmenopausal women, 26 premenopausal women and 65 men). The clinical forms of PsA were: 46% oligoarticular and 54% polyarticular. Mean disease duration was 13.7±9.4 years and mean ESR was 21.8±13.9mm/h; 66% of patients had received glucocorticoid treatment. We found no differences in BMD status between the patients and the Spanish general population, neither in the whole series nor in each defined subgroup. Frequency of osteoporosis was 16%; it was higher in postmenopausal women (28%) than in men (9%) or premenopausal women (4%). Frequency of clinical fractures was 13%; it accounted specially in postmenopausal women.


The magnitude of the problem of osteoporosis in PsA seems to be mild.
