[Clinical management of psoriatic arthritis in Spain: the CALIPSO study].
OBJECTIVE
To describe the clinical management of psoriatic arthritis for patients being treated by dermatologists and rheumatologists in Spain.


METHODS
Multicenter, retrospective, naturalistic observational study in which demographic and clinical variables were recorded for patients diagnosed with psoriatic arthritis. Data referred to the previous 12 months and were collected during a single visit with the physician.


RESULTS
A total of 266 patients were enrolled; 78.1% were being treated by rheumatologists and 21.9% by dermatologists. The data covered 1138 visits. The main reason for consulting a physician was to monitor psoriatic arthritis (82.7% of the visits). The most widely used examination was to determine the tender- and swollen-joint count (73.1%). The tests most frequently ordered were acute-phase reactants: erythrocyte sedimentation rate (79.8%) and C reactive protein level (74.5%). Affected body surface area and the Psoriasis Area and Severity Index were the main assessments used by dermatologists. Rheumatologists tended to examine the joints and record biochemical markers. A disease-modifying antirheumatic drug was prescribed for 71.1% of the patients; 51.8% were prescribed a biologic agent (61.5% in combination with another treatment). Treatment approach differed by specialty and was modified if response was nil or partial (the rationale for 45.1% of all changes).


CONCLUSIONS
Differences in the management of psoriatic arthritis in dermatology and rheumatology were evident in both diagnostic and treatment approaches. These 2 specialties should cooperate to establish common practice guidelines for use in Spain.
