Brief Summary:
The purpose of this study is to define cut-off values of the most widely used composite scores and patient-reported outcomes, for levels corresponding to remission/low disease activity and for changes in levels corresponding to flares, in PsA, when remission/low disease activity and flare are defined from the patient and physician perspective. The ReFlaP (Remission/Flare in PsA) study is a prospective, multicentric international, longitudinal, observational study.

Primary Outcome Measures :
  1. To determine the cutoff value of PsAID corresponding to flare [ Time Frame: 6 months ]

    For flare, the gold standard will be decision of treatment intensification. The primary outcome will be to determine the cutoff value of PsAID corresponding flare.

    The PsAID is a questionnaire (paper CRF) that can be used to calculate a score reflecting the impact of psoriatic arthritis (PsA) from the patients' perspective. (Gossec L et al., A patient-derived and patient-reported outcome measure for assessing psoriatic arthritis: elaboration and preliminary validation of the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire, a 13-country EULAR initiative. Ann Rheum Dis. 2014;73(6):1012-9).

  2. To determine the cutoff value of PsAID corresponding to remission [ Time Frame: 6 months ]
    For remission, the gold standard will be Minimal Disease Activity. The primary outcome will be to determine the cutoff value of PsAID corresponding to remission. Patients are classified as achieving Minimal Disease Activity if they fulfill 5 of 7 outcome measures: tender joint count ≤1; swollen joint count ≤1; psoriasis activity and severity index ≤1 or body surface area ≤3; patient pain visual analog scale (VAS) score of ≤15; patient global disease activity VAS score of ≤20; Health Assessment Questionnaire (HAQ) score ≤0.5; and tender entheseal points ≤1. (L C Coates, J Fransen, P S Helliwell Defining minimal disease activity in psoriatic arthritis: a proposed objective target for treatment Clinical and epidemiological research Ann Rheum Dis 2010;69:48-53.)

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Over the 6 months recruitment period, all patients with definite PsA who satisfy the inclusion criteria, seen in outpatient visits in the participating centers by one of the investigators, will be asked to participate. It is planned to take place in 6 participating centres in France, 15 other European tertiary rheumatology centers (Germany, Hungary, Ireland, Italy, Norway, Romania, Spain, Turkey and the UK), 4 centers in the USA, 2 centers in Canada, 1 in Brazil, and 2 in Asia (Singapore and Russia).It is planned that in each center, 15-30 patients will be included. The first 15-30 consecutive patients will be selected in each center to reduce bias selection.

Inclusion Criteria:

  • Age>18 years
  • Definite PsA according to the ClASsification of Psoriatic ARthritis (CASPAR) criteria and diagnosis confirmed by a rheumatologist. (Taylor2006)
  • Willingness to participate and signed informed consent.
  • There are no inclusion criteria based on disease activity or treatment
  • Patients with more than 2 years of disease duration will be included in the study for more homogeneity.

Patient will be included consecutively. A registry will be kept locally to note the age and gender of patients who have been proposed the study but refused to participate.

Exclusion Criteria:

  • No definite PsA or less than 2 years of disease duration
  • Patients who don't speak or read the local language or are not comfortable filling in a paper CRF in the local language.
