Background One of the most salient features of psoriatic arthritis is the wide variety of clinical manifesta-tions it can exhibit. This facilitates interrelationships among its clinical forms and changes from one to another.
Objectives To evaluate the clinical manifestations of patients with psoriatic arthritis of initially oligo-articular form after a course of five years.
Methods An overall 32 patients with psoriatic arthritis of initially oligoarticular form (viz. with fewer than three joints affected in an unsymmetric form) were examined and the specific form prevailing after a course of five years was determined. Simultaneously, clinical activity was studied on the basis of the following criteria: (a) morning stiffness for less than 15 min; (b) absence of fatigue; (c) absence of articular pain; (d) absence of pain in response to pressure or movement; (e) absence of swollen joints; (f) VSG below 30. Those patients fulfilling at least five of the previous six criteria were considered to be in remission.
Results The following Table 1 classifies the patients according to status and clinical form of the disease.
Conclusion Our results confirm that oligoarticular forms of psoriatic arthritis are not static, but rather change during the course of the disease.
