Objective:
To analyze the clinical and laboratory features of psoriatic arthritis (PsA) which antedates psoriasis.
Methods:
The clinical and laboratory data including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), immunoglobulins, antibodies of 113 patients with PsA were analyzed retrospectively and compared by order of the occurrence of arthritis.
Results:
The occurrence of psoriatic arthritis which antedates psoriasis was 22.1% in the study. The onset of arthritis was 2 months to 25 years earlier than psoriasis. Arthritis of distal interphalangeal (DIP) joints was frequently involved in this group and arthritis of hip joints was rare. Positive HLA-B27 and higher level of platelet (PLT), ESR, CRP, and IgA were common in patients with psoriatic arthritis which antedates psoriasis.
Conclusion:
Arthritis of DIP joints and elevated inflammatory markers are frequently involved in patients with psoriatic arthritis which antedates psoriasis, and somewhat they are associated with disease activity.
