Chronic arthritis (CA) is an unusual condition in childhood-onset systemic lupus erythematosus (cSLE) and data in children is very limited. The aim of the study is to assess CA in a large population of cSLE patients, in a multicenter cross-sectional study including 852 cSLE patients followed in ten Pediatric Rheumatology referral services in state of São Paulo, Brazil. CA was observed in 32/852 (3.7 %) cSLE patients mostly in hands and ankles. Chronic monoarthritis was diagnosed in four cSLE patients, oligoarthritis in nine and polyarthritis in 19. In the latter group, six had rhupus syndrome. Two oligoarticular patients had Jaccoud's arthropathy. CA was an isolated manifestation observed at disease onset in 13/32 (41 %) cSLE patients, and juvenile idiopathic arthritis (JIA) was the first diagnosis in 18/32 (56 %). The comparison of last visit of patients with CA and without this manifestation revealed higher frequency of splenomegaly (28 vs. 11 %, p = 0.002). The median of SLICC/ACR-DI score [1(0-9) vs. 0(0-7), p = 0.003] was significantly higher in CA patients compared to patients without this manifestation, likewise the frequency of musculoskeletal damage (31 vs. 9 % p = 0.001). Frequencies of treatment with nonsteroidal anti-inflammatory drugs (75 vs. 26 %, p < 0.0001), hydroxychloroquine sulfate (87 vs. 59 %, p = 0.001) and methotrexate (47 vs. 22 %, p = 0.001) were significantly higher in CA patients. This large multicenter study allowed us to characterize CA as a rare and early manifestation of cSLE, frequently mimicking JIA at disease onset. It is predominantly polyarticular, involving more often hands and ankles and it is associated with significant musculoskeletal accrual damage.

Objective: To develop, implement and evaluate an online virtual learning environment (VLE) on pediatric rheumatology, aimed at pediatric residents, analyzing its effectiveness and satisfaction rates. Methods: A total of 92 first and second year pediatric residents at two pediatric reference centers were invited to participate in the study. Residents were randomized into a case group (that answered the pre-course test, attended the six virtual pediatric rheumatology modules, and then responded to the post-course test and a satisfaction questionnaire) and a control group (that only answered the pre-course test and, after 4 weeks, the post-course test). Results: Forty-seven residents (51%) completed their participation. In the case group (n=24), the mean percentage of correct answers was 14% higher on the post-course test (p<0.001). The number of correct answers was larger in the case group than in the control one (n=23) in the post-course test (p=0.045). In the assessment of satisfaction with VLE use, residents considered the site easy to navigate (91%), suitable as a learning tool (91%), and attractive in design (79%). They reported poor prior knowledge in pediatric rheumatology (91%) and agreed that there was good learning with the methodology (75%). Conclusions: The virtual learning environment in pediatric rheumatology proved to be an effective teaching tool with high satisfaction rates, providing pediatrician residents with adequate knowledge regarding the initial assessment and management of children with rheumatic diseases.

In our study, more than half of the joints showed a good response to IIC. Younger patients at diagnosis and uveitis during the course of the disease had good response to IIC. Knees, wrists and elbows were the joints that best responded to IIC. IIC proved to be a safe procedure.
