Juvenile idiopathic arthritis – risk factors and clinical forms
The aim of this article is to determine the JIA’s risk factors and the prevalence of clinical forms, poiting out the difficulties of situating them at onset as well as in evolution taking into consideration a significant number of patients (169 cases). The outlined clinical forms (in order of frequency) were: oligoarthritis (44,17%), RFnegative polyarthritis (33.13%), enthesitis (11.24%), systemic arthritis (5.91%), RF-positive polyarthritis (2, 95%) and psoriatic arthritis (2.36%), with the percentage values close to those of other studies, except the RF-negative polyarthritis subtype in which the frequency is higher. Individualized analysis of cases revealed real time from onset of disease to diagnosis and risk factors for JIA (in order of frequency): traumatic (9,46%), positive family history (5,32%) and infections (2,35%). Also, it emphasized the possibility of transforming a clinical form to another even under adequate treatment.
