Objective: The SARS-CoV-2 pandemic has induced an exceptional sanitary crisis, potentially having an impact on treatment continuation, for juvenile idiopathic arthritis (JIA) patients receiving immunosuppressive therapies. After national lockdowns, many patients were also concerned about their safety at school. We evaluated the impact of the pandemic on the optimal continuation of treatment and on the return to school in JIA patients.Methods: JIA patients under 18 years of age, usually treated with disease-modifying anti-rheumatic drugs (DMARDs) were prospectively included during their outpatient visit and completed a standardized questionnaire. The primary outcome was DMARD treatment modification in relation to the context of the pandemic but we also evaluated the pandemic's impact on the schooling.Results: One hundred and seventy three patients from 8 different expert centers were included between May and August 2020. Their mean age was 11.6 years (± 4.1 years), and most of them 31.2% (54/173) had a rheumatoid factor-negative polyarticular JIA. Fifty percent (86/172) were treated with methotrexate, and 72.5% (124/171) were treated with bDMARDs. DMARD treatment modification in relation to the pandemic was observed in 4.0% (7/173) of participants. 49.1% (81/165) of the patients did not return to school due to a personal/parental decision in 69.9% (55/81) of cases. Two patients were diagnosed positive for SARS-CoV-2 infection.Conclusion: This study suggests that JIA patients treated with DMARDs continued their treatment during the pandemic and were rarely affected by symptomatic COVID-19. In contrast, parents' reluctance was a major obstacle for returning to school. Therefore, more solidified school reopening strategies should be developed.

Background Surgeries for idiopathic uveitis and juvenile idiopathic arthritis-associated uveitis in children are complex because of the high risk of inflammatory postoperative complications. There is no consensus about treatment adaptation during the perioperative period. The objectives of this study are to report the therapeutic changes made in France and to determine whether maintaining or stopping immunosuppressive therapies is associated with an increased risk of surgical site infection or an increased risk of uveitis or arthritis flare-up. Methods We conducted a retrospective cohort study between January 1, 2006 and December 31, 2018 in six large University Hospitals in France. Inclusion criteria were chronic idiopathic uveitis or chronic uveitis associated with juvenile idiopathic arthritis under immunosuppressive therapies at the time of the surgical procedure, operated before the age of 16. Data on perioperative treatments, inflammatory relapses and post-operative infections were collected. Results A total of 76 surgeries (42% cataract surgeries, 30% glaucoma surgeries and 16% posterior capsule opacification surgeries) were performed on 37 children. Adaptation protocols were different in the six hospitals. Immunosuppressive therapies were discontinued in five cases (7%) before surgery. All the children in the discontinuation group had an inflammatory relapse within 3 months after surgery compared to only 25% in the other group. There were no postoperative infections. Conclusions The results of this study show varying practices between centres. The benefit-risk balance seems to favour maintaining immunosuppressive therapies during surgery. Further studies are needed to determine the optimal perioperative treatments required to limit post-operative inflammatory relapses.

Background:The SARS-CoV-2 pandemic has induced an exceptional sanitary crisis, potentially having an impact on treatment continuation, for juvenile idiopathic arthritis (JIA) patients receiving immunosuppressive therapies. In France, after the first lockdown from March to May 2020, many parents and children were then also concerned about whether reopening plans for school could ensure the safety of students, despite data concerning children with COVID-19 seem reassuring, and very few of them develop severe forms of the disease (1, 2, 3).Objectives:Our objectives were to evaluate the impact of the COVID-19 pandemic on the therapeutic management of JIA, the frequency of returning to school after the first lockdown period and the prevalence of SARS-CoV-2 infection at the time of the survey.Methods:JIA patients under 18 years of age, usually treated with disease-modifying anti-rheumatic drugs (DMARDs) were prospectively included during their outpatient visit and completed a standardized questionnaire. Data regarding the general characteristics of the participants, medical history, SARS-CoV-2 infection, characteristics of JIA subtypes and treatment modifications were collected.Results:A total of 173 patients from 8 different expert centers were included between May and August 2020. Their mean age was 11.6 years (± 4.1 years), and most of them 31.2% (54/173) had a rheumatoid factor-negative polyarticular JIA. Fifty percent (86/172) were treated with methotrexate, and 72.5% (124/171) were treated with bDMARDs. DMARD treatment modification in relation to the pandemic was observed in 4.0% (7/173) of participants, our results reflect good adherence of the patient/parents to their immunosuppressive treatments. 49.1% (81/165) of the patients did not return to school due to a personal/parental decision in 69.9% (55/81) of cases, due to anxiety of the patient/parents regarding COVID-19. Two patients were diagnosed positive for SARS-CoV-2 infection.Conclusion:This study suggests that JIA patients treated with DMARDs continued their treatment during the pandemic. In contrast, parents’ reluctance was a major obstacle for returning to school. Therefore, more solidified school reopening strategies should be developed.References:[1]Filocamo G, et al. “Absence of severe complications from SARS-CoV-2 infection in children with rheumatic diseases treated with biologic drugs.” J Rheumatol. 25 avr 2020;[2]Tagarro A, et al. “Screening and Severity of Coronavirus Disease 2019 (COVID-19) in Children in Madrid, Spain.” JAMA Pediatr. 8 avr 2020;[3]Lu X, et al. « SARS-CoV-2 Infection in Children”.

Background Systemic juvenile idiopathic arthritis (sJIA) is a serious disease with significant morbimortality. Management of sJIA has improved dramatically over the last decade, especially with IL-1 receptor antagonists (IL-1Ra), but treatment remains heterogeneous. In this study, we described the evolution of patients with sJIA treated with IL1Ra, mainly as first-line therapy. Methods In this single-center retrospective observational study, we included all patients with sJIA treated with anakinra (ANK) between 2006 and 2020. Results Twenty-four patients received ANK after a median delay of 28 days (range 0–2070 days) after the diagnosis of sJIA. The median follow-up time was 2.37 years (range 0.49–10.75 years). Only 7/24 (29%) patients received corticosteroids. Inactive disease was observed in 18/24 (75%) patients at 3 months. Remission was observed in 19/23 (83%) patients at 1 year. At last available follow-up, 16/24 (67%) patients were in remission attributable to ANK and treatment-free remission was observed in 12/24 (50%) patients. Remission attributable to ANK was obtained in 12/15 (80%) patients treated with ANK within the first 3 months of the disease versus 4/9 (44%) patients treated after 3 months (p = 0.1). An initial White Blood Count ≥ 20 G/L was associated with remission attributable to ANK (p = 0.03). The only death occurred in a patient with a long-standing disease before ANK initiation and was attributable to the disease. Adverse events observed included ear, nose and throat infections and one transient liver cytolysis. Conclusions ANK in sJIA allows rapid remission with few adverse events. Their early use, as a firts-line therapy would allow rapid remission while avoiding the side effects of corticosteroids. Trial registration: retrospectively registered.
