Ozdel S, Baglan E, Cakıcı EK, et al. - In the present study, the researchers sought to examine the frequency of juvenile idiopathic arthritis (JIA) subtypes, patient demographic and clinical characteristics, as well as the rates of macrophage activation syndrome, uveitis, and remission in Turkish JIA patients treated at a single center, and to compare the findings with those in the literature. The sample consisted of 305 patients (180 females) with a mean age at onset of 7.83 ± 4.62 years. Among all the JIA subtypes, the most frequent was oligoarthritis, followed by enthesitis‐related arthritis, rheumatoid factor (RF)‐negative polyarthritis systemic arthritis, RF‐positive polyarthritis, psoriatic arthritis, and undifferentiated arthritis. The available evidence suggests that JIA as a whole is a heterogeneous disease with significant variability in the course and long‐term outcome. As such, according to his/her disease subtype, each patient should be assessed.
