The heterogeneous course and prognosis of early arthritis (EA) patients continues to be a major challenge for clinicians involved in the management of these patients. A variable proportion of EA patients can be classified under rheumatoid arthritis (RA) or another disease (e.g. spondylarthritis and lupus) during the follow-up, while others remain undifferentiated or resolve spontaneously. In cohort studies of EA, the cumulative prevalence of RA varied significantly and was reported between 7 and 42%, which indicates that selection factors may influence the outcome of such cohorts [1].
Identifying EA patients at risk for developing persistent and/or erosive arthritis is mandatory for selecting a treatment strategy according to the current early aggressive treatment approach [2]. It has been widely discussed that the current ACR 1987 classification criteria for RA is not an appropriate tool for treatment purposes in the very early phase of the disease mainly because
