This article outlines our case-control, prospective, 6-year followup study to evaluate the frequency of clinical remission and duration of remission episodes in patients with peripheral psoriatic arthritis (PsA). All case patients were consecutive new outpatients with peripheral PsA requiring second-line drugs. Controls were consecutive new outpatients with rheumatoid arthritis (RA). Modified American College of Rheumatology criteria for RA were used to assess the remission in patients with PsA. One or more episodes of remission occurred in 57/236 (24.1%) PsA patients and in 20/268 (7.5%) controls (p < 0.001). No significant difference was recorded for duration of remissions between the group receiving traditional disease modifying antirheumatic drug (DMARD) and the anti-tumor necrosis factor (TNF) group: 11 +/- 7.2 and 13.3 +/- 8.1 months, respectively (p = NS). The duration of remission after interruption of therapy was 12 +/- 2.4 months for the PsA group and 3 +/- 1.5 months for patients with RA (p < 0.001). No predictor of remission at diagnosis could be determined by multivariate analysis. Based on our findings, remission is possible in up to 24% of patients with peripheral PsA. It is significantly more frequent, but not longer, in patients receiving anti-TNF drugs compared to those treated with traditional DMARD.
