Sars-Cov-2 Vaccine Safety in Adolescents with Inflammatory Rheumatic and Musculoskeletal Diseases and Adults with Juvenile Idiopathic Arthritis: Data from the Eular Covax Physicianreported Registry

Introduction/Background: There is a lack of data on Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination safety in children and young people (CYP) with rheumatic and musculoskeletal diseases (RMDs) as they were excluded from initial vaccine trials. Vaccination guidance is based on data from adults with or CYP without RMDs. Description/Method: Our objective was to describe the safety of SARS-COV-2 vaccination in adolescents with inflammatory RMDs and adults with JIA. We described patient characteristics, flares, and adverse events in adolescent cases under 18 with inflammatory RMDs and adult cases aged 18 or above with JIA submitted to the European Alliance of Associations for Rheumatology (EULAR) COVAX registry. Discussion/Results: Thirty-six adolescent cases were reported from 4 countries, mostly female (58%) with JIA (42%: 28% non-systemic JIA, 14% systemic JIA) and a median age of 15 [IQR: 14.5, 17]. Most were in remission (64%) or had minimal (22%) disease activity at the time of vaccination. Over half of the adolescent group (56%) reported early reactogenic-like AEs. One mild polyarthralgia flare and one serious AE of special interest (malaise) were reported. No CYP reported SARS-CoV-2 infection post-vaccination. No cases of paediatric inflammatory multi-system syndrome or myocarditis adverse events were reported. Seventy-four adult JIA cases were reported from 11 countries;73% were female with a median age of 26 [IQR: 23, 31]. Eight-five percent had ns-JIA and 15% had s-JIA. Almost two thirds (62%) reported early reactogenic-like AEs and two flares were reported (mild polyarthralgia and moderate uveitis). No serious AEs of special interest were reported among adults with JIA. Three 20-30 year old females were diagnosed with SARS-CoV-2 post-vaccination;all fully recovered. Key learning points/Conclusion: In this observational registry dataset, SARS-CoV-2 vaccines appeared safe in adolescents with RMDs and adults with JIA, with a low frequency of disease flares, serious AEs, and SARS-CoV-2 re-infection seen in both populations.

SARS-COV-2 VACCINE SAFETY in ADOLESCENTS with INFLAMMATORY RHEUMATIC and MUSCULOSKELETAL DISEASES and ADULTS with JUVENILE IDIOPATHIC ARTHRITIS

Background: There is a lack of data on Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination safety in children and young people (CYP) with rheumatic and musculoskeletal diseases (RMDs). Current vaccination guidance is based on data from adults with RMDs or CYP without RMDs. Objectives: To describe the characteristics and outcomes of adolescents with infammatory RMDs and adults with juvenile idiopathic arthritis (JIA) vaccinated against SARS-CoV-2. Methods: We described patient characteristics, fares, and adverse events in adolescent cases under 18 with infammatory RMDs and adult cases aged 18 or above with JIA submitted to the European Alliance of Associations for Rheumatology (EULAR) COVAX registry. Results: Thirty-six adolescent cases were reported from 4 countries, the most frequent diagnosis was JIA (42%). Over half (56%) reported early reactogen-ic-like adverse events (AEs) experienced within 7 days of vaccination. One mild polyarthralgia fare and one serious AE (malaise) were reported. No CYP reported SARS-CoV-2 infection post-vaccination. In addition to the adolescent cases, eleven countries reported 74 adult JIA cases. Among these, 62% reported early reactogenic-like AEs and two fares were reported (mild polyarthralgia and moderate uveitis). No serious AEs of special interest were reported among adults with JIA. Three 20-30 year old females were diagnosed with SARS-CoV-2 post-vaccination;all fully recovered. Conclusion: In this observational registry dataset, SARS-CoV-2 vaccines appeared safe in adolescents with RMDs and adults with JIA, with a low frequency of disease fares, serious AEs, and SARS-CoV-2 re-infection seen in both populations.

Remote learning behavioral study: An observational study among students in the pre-k, elementary and middle school age groups

Researchers wanted to identify possible concerns and trends arising during COVID-19 remote learning. The problem is, many schools, students, and students' families were thrown into remote learning without much preparation for the sudden change in education made necessary by a pandemic. We sought to investigate non-academic areas in which the pandemic impacted the lives of children such as nutrition, socialization, and physical activity. Hopefully, this article raises questions about the phenomenon of remote learning. It is intended to be a tool of observation to ask questions, not answer them.

Outcomes of COVID-19 infection among children and young people with pre-existing rheumatic and musculoskeletal diseases

Introduction: It remains unknown whether children and young people with rheumatic and musculoskeletal diseases (RMD) who acquire COVID-19 infection have a more severe COVID-19 course, due to either underlying disease or immunosuppressive treatments. Objectives: To describe outcomes among children and young people with underlying RMD who acquire COVID-19 infection. Methods: All children and young people <19 years of age with COVID-19 (presumptive or confirmed) reported to the EULAR COVID- 19 Database, which collects details regarding RMD diagnosis and treatment, COVID infection and outcomes, between 27 March 2020 and 9 April 2021 (cut-off date for this analysis) were included. Patient characteristics and COVID-19 outcomes are presented. Results: A total of 364 children and young people (age range 2-18 years;table) have been reported to the database from 17 countries;mostly France (N=71), Germany (N=71), Czechia (N=59), Spain (N= 50), Israel (N=60), and UK (N=25). Most patients had a diagnosis of juvenile idiopathic arthritis (JIA;N=244;67%). There were 20 (5%) hospitalisations and 1 death reported due to COVID-19. The most commonly reported symptoms were fever (40%) and cough (30%). Only 42 (12%) patients reported glucocorticoid use. Any DMARD therapy was used by 251 (69%) patients;161 (44%) were on csDMARDs, 119 (33%) on anti-TNF. 40% were in remission at time of COVID-19 infection, 28% in low, and 9% in moderate/high disease activity. Among those with hospitalisation data [N=290], patients on any DMARD therapy (cs/b/tsDMARDs) had similar odds for hospitalisation compared with those not on therapy, adjusted for age, sex, rheumatic disease, and disease severity (odds ratio 1.3;95% CI 0.3, 4.6). Conclusion: These initial data on outcomes of COVID-19 infection in paediatric RMDs are very reassuring, only one-in-twenty patients were reported to be hospitalised. Due to the database design and inherent reporting bias, this is likely an overestimate, suggesting that overall outcomes among this population appear to be generally good, with mild infection. Increasing case reports to the database will allow further exploration of drug- and disease-specific outcomes.

Patient characteristics and COVID-19 outcomes are presented. Results: A total of 151 children and young people (age range 2-17 years;Table 1) have been reported to the database from 12 countries;mostly Spain (N=30), France (N=29), Israel (N=29), and Czechia (N=25). Most patients had a diagnosis of juvenile idiopathic arthritis (JIA;N=92;61%). Other diagnoses were autoinflammatory syndrome (including TRAPS, CAPS, FMF;12%), and systemic lupus erythematosus (4%). There were 14 (9%) hospitalisations and 1 (0.7%) death reported due to COVID-19. The most commonly reported symptoms were fever (46%), cough (34%), anosmia (19%), and headache (19%). Only 19 (13%) patients reported glucocorticoid use. DMARD therapy was used by 104 (69%) patients;67 (44%) were on csDMARDs (methotrexate [N=54], antimalarials [N=7]), 45 (30%) on anti-TNF, 9 (6%) on IL-6 inhibitors, and 7 (5%) on IL-1 inhibitors. Among the 145 patients with hospitalisation data, patients on any DMARD therapy (cs/b/tsDMARDs) had similar odds for hospitalisation compared with those not on therapy, adjusted for age (odds ratio 0.7;95% CI 0.2, 2.4). Conclusion: These initial data on outcomes of COVID-19 in paediatric RMDs are very reassuring, with less than 1 in 10 patients reporting hospitalisation. Due to the database design and inherent reporting bias, this is likely an overestimate, suggesting that overall outcomes among this population appear to be generally good, with mild infection. Increasing case reports to the database will allow further exploration of drug-and disease-specific outcomes.
