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.

Increased COVID-19 mortality in patients with rheumatic diseases: results from the CONTROL-19 study by the Italian Society for Rheumatology

OBJECTIVES: To investigate differences in coronavirus disease 2019 (COVID-19) mortality between patients with rheumatic musculoskeletal diseases (RMD) and the general population in Italy. METHODS: We analysed the data from the national surveillance study promoted by the Italian Society for Rheumatology (CONTROL-19 database) including patients with RMD and COVID-19 between 26 March 2020 and 29 November 2020, compared with official data from the Italian population (within the same period) adjusted for age, sex and geographic location. The main outcome of the analyses was mortality. The relationship between RMD and mortality was analysed using adjusted logistic models and sensitivity analyses were conducted to support the robustness of our results. RESULTS: We included 668 RMD patients (62.7% with inflammatory arthritis, 28.6% with systemic autoimmune diseases), who had a mean age of 58.4 years and of which 66% were female. Compared to the general population, the RMD population showed an increased risk of death (OR 3.10 (95% CI 2.29-4.12)), independently from the differences in age and sex distribution. Even after considering the potential influence of surveillance bias, the OR was 2.08 (95% CI: 1.55-2.73). Such excess of risk was more evident in the subgroup of younger patients, and more consistent in women. Subjects with systemic autoimmune diseases showed a higher risk of death than patients with any other RMDs. CONCLUSIONS: Patients with RMD and COVID-19 infection evidenced a significant increase in mortality during the first pandemic phases in Italy. These findings support the need for strong SARS-CoV-2 prevention in patients with rheumatic diseases.

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.

Tolérance de la vaccination contre le SRAS-CoV-2 chez les patients atteints de maladies rhumatologiques inflammatoires/auto-immunes : résultats du registre EULAR-COVAX chez 5121 patients

Introduction Les patients atteints de maladies musculosquelettiques inflammatoires/auto-immunes (I-RMD) n’ont pas été inclus dans les études de tolérance des vaccins contre le SARS-CoV-2 et sont souvent inquiets quant à la tolérance de la vaccination. Notre objectif est d’étudier la tolérance des vaccins contre le SARS-CoV-2 chez les patients atteints de maladies musculosquelettiques inflammatoires/auto-immunes (I-RMD). Patients et méthodes Pour cela, nous avons créé avec l’EULAR un registre international de cas rapportés par les médecins rhumatologues et internistes de patients atteints d’I-RMD et de RMD non inflammatoire (NI-RMD) vaccinés contre le SARS-CoV-2. Du 5 février 2021 au 27 juillet 2021, nous avons recueilli des données sur la démographie, la vaccination, le diagnostic de RMD, l’activité de la maladie, les traitements immunomodulateurs/immunosuppresseurs, les poussées, les événements indésirables (EI) et les infections COVID-19 chez les patients vaccinés. Les données ont été analysées de manière descriptive. Résultats L’étude a inclus 5121 participants de 30 pays, la majorité de France (40 %), Italie (16 %) et Portugal (14 %), 90 % avec des I-RMD (n=4604, 68 % de femmes, âge moyen 60,5 ans) et 10 % avec des NI-RMD (n=517), 77 % de femmes, âge moyen 71,4 ans. La polyarthrite rhumatoïde (33 %), les connectivites (18 %), les spondyloarthrites (11 %), le rhumatisme psoriaqique (10 %) et les vascularites (12 %) étaient les diagnostics les plus fréquents ;54 % des patients ont reçu des traitements de fond synthétiques conventionnels (csDMARD), 42 % des DMARD biologiques ou ciblés et 35 % des immunosuppresseurs. La plupart des patients ont reçu le vaccin Pfizer/BioNTech (70 %), 17 % AstraZeneca/Oxford et 8 % Moderna. Une infection COVID post-vaccination a été signalée dans 0,7 à 1,1 % des cas, selon le statut vaccinal (entièrement/partiellement vacciné) et le groupe RMD. Des poussées d’I-RMD ont été signalées dans 4,4 % des cas (0,6 % de poussées sévères), dont 1,5 % ont entraîné des changements de médicaments. Des EI ont été signalés dans 37 % des cas (37 % I-RMD, 40 % NI-RMD), des EI sévères dans 0,4 % des cas, très divers et avec une fréquence comparable et même inférieure à celle observée chez les patients atteints de NI-RMD (1,1 %). Discussion La tolérance au vaccin n’était pas différente entre les groupes I-RMD et NI-RMD. Dans les essais cliniques de vaccins à ARN contre le SRAS-CoV-2 dans la population générale, les taux d’EI graves étaient très semblables à ceux de notre étude, allant de 0,4 % à 0,6 % dans le groupe vacciné et de 0,5 % à 0,6 % dans le groupe témoin, ce qui suggère que ces EI graves ne sont pas nécessairement liés au vaccin. Conclusion Il s’agit de la plus grande étude de la tolérance des vaccins anti-SRAS-CoV-2 chez près de 5000 patients atteints de maladies inflammatoires/auto-immunes rhumatologiques. Le profil de sécurité des vaccins contre le SRAS-CoV-2 chez les patients atteints d’I-RMD était rassurant, et comparable à celui des patients atteints de NI-RMD. La majorité des patients ont bien toléré leur vaccination, avec de rares poussée d’I-RMD et de très rares EI sévères probablement non liés à la vaccination. Ces résultats devraient rassurer les rhumatologues et les personnes vaccinées, et favoriser la confiance dans la sécurité du vaccin COVID-19 chez les patients atteints de I-RMD.

COVID-19 vaccine safety in patients with rheumatic and musculoskeletal disease

Background: The consequences of the COVID-19 outbreak are unprecedented and have been felt by everyone around the world, including people with rheumatic and musculoskeletal diseases (RMDs). With the development of vaccines, the future is becoming brighter. Vaccines are a key pillar of public health and have been proven to prevent many serious diseases. However, vaccination also raises questions, especially for patients with inflammatory RMDs and/or treated with drugs that influence their immune system. Objectives: Our aim was to collect safety data among RMD patients receiving COVID-19 vaccines. Methods: The EULAR COVID-19 Vaccination (COVAX) Registry is an observational registry launched on 5 February 2021. Data are entered voluntarily by clinicians or associated healthcare staff;patients are eligible for inclusion if they have an RMD and have been vaccinated against SARS-CoV-2. Descriptive statistics are presented. Results: As of 27 April 2021, 1519 patients were reported to the registry. The majority were female (68%) and above the age of 60 (57%). Mean age was 63 years (SD 16), ranging from 15 to 97 years. A total of 28 countries contributed to the registry, with France (60%) and Italy (13%) as the highest contributors. The majority (91%) had inflammatory RMDs. Inflammatory joint diseases accounted for 51% of cases, connective tissue diseases 19%, vasculitis 16%, other immune mediated inflammatory diseases 4%, and non-inflammatory/mechanical RMDs 9%. The most frequent individual diagnoses were rheumatoid arthritis (30%), axial spondyloarthritis (8%), psoriatic arthritis (8%), systemic lupus erythematosus (SLE, 7%) and polymyalgia rheumatica (6%). At the time of vaccination, 45% were taking conventional synthetic DMARDs, 36% biological DMARDs, 31% systemic glucocorticoids, 6% other immunosuppressants (azathioprine;mycophenolate;cyclosporine;cyclophosphamide;tacrolimus), and 3% targeted synthetic DMARDs. The most frequent individual DMARDs were methotrexate (29%), TNF-inhibitors (18%), antimalarials (10%) and rituximab (6%). The vaccines administered were: 78% Pfizer, 16% AstraZeneca, 5% Moderna and 1% other/unknown;66% of cases received two doses and 34% one dose. Mean time from 1st and 2nd dose to case report was 41 days (SD 26) and 26 days (SD 23), respectively. COVID-19 diagnosis after vaccination was reported in 1% (18/1519) of cases. Mean time from first vaccination until COVID-19 diagnosis was 24 days (SD 17). Disease flares were reported by 5% (73/1375) of patients with inflammatory RMDs, with 1.2% (17/1375) classified as severe flares. Mean time from closest vaccination date to inflammatory RMD flare was 5 days (SD 5). The most common flare types were arthritis (35/1375=2.5%), arthralgia (29/1375=2.1%), cutaneous flare (11/1375=0.8%) and increase in fatigue (11/1375=0.8%). Potential vaccine side effects were reported by 31% of patients (467/1519). The majority were typical early adverse events within 7 days of vaccination, namely pain at the site of injection (281/1519=19%), fatigue (171/1519=11%) and headache (103/1519=7%). Organ/system adverse events were reported by 2% (33/1519) but only 0.1% (2/1519) reported severe adverse events, namely a case of hemiparesis in a patient with systemic sclerosis/ SLE overlap syndrome (ongoing at the time of reporting), and a case of giant cell arteritis in a patient with osteoarthritis (recovered/resolved without sequelae). Conclusion: The safety profiles for COVID-19 vaccines in RMD patients was reassuring. Most adverse events were the same as in the general population, they were non-serious and involved short term local and systemic symptoms. The overwhelming majority of patients tolerated their vaccination well with rare reports of inflammatory RMD flare (5%;1.2% severe) and very rare reports of severe adverse events (0.1%). These initial findings should provide reassurance to rheumatologists and vaccine recipients, and promote confidence in COVID-19 vaccine safety in RMD patients, namely those with inflammatory RMDs and/or taking treatments that influence their immune system.
