Objective, To determine the frequency of remission in psoriatic arthritis (
PsA), to describe the characteristics of remission in PsA, and to identify
features associated with remission in PsA.
Methods. Patients with PsA are followed prospectively according to a standa
rd protocol. Only patients with greater than or equal to3 visits and those
with peripheral arthritis were included in this study. Patients who sustain
ed remission, defined as no actively inflamed joints on at least 3 consecut
ive visits, were compared to patients with persistent inflammation througho
ut the followup period (nonremission).
Results. Among 391 patients with peripheral arthritis and greater than or e
qual to3 visits, 69 patients sustained remission and 175 had persistent inf
lammatory activity. The frequency of remission was thus 17.6%. The average
duration of remission was 2.6 years. However, 52% of the patients experienc
ed flare after a mean of 1.8 years. Univariate analyses revealed that male
sex, fewer actively inflamed and damaged joints, and better functional clas
s at presentation to clinic were associated with remission.
Conclusion. Remission does occur in PsA and may be prolonged. There are cli
nical characteristics of patients at their first clinic Visit that are asso
ciated with future remission.
