EULAR/PRES recommendations for vaccination of paediatric patients with autoimmune inflammatory rheumatic diseases: update 2021.

OBJECTIVES: Recent insights supporting the safety of live-attenuated vaccines and novel studies on the immunogenicity of vaccinations in the era of biological disease-modifying antirheumatic drugs in paediatric patients with autoimmune/inflammatory rheumatic diseases (pedAIIRD) necessitated updating the EULAR recommendations. METHODS: Recommendations were developed using the EULAR standard operating procedures. Two international expert committees were formed to update the vaccination recommendations for both paediatric and adult patients with AIIRD. After a systematic literature review, separate recommendations were formulated for paediatric and adult patients. For pedAIIRD, six overarching principles and seven recommendations were formulated and provided with the level of evidence, strength of recommendation and Task Force level of agreement. RESULTS: In general, the National Immunisation Programmes (NIP) should be followed and assessed yearly by the treating specialist. If possible, vaccinations should be administered prior to immunosuppressive drugs, but necessary treatment should never be postponed. Non-live vaccines can be safely given to immunosuppressed pedAIIRD patients. Mainly, seroprotection is preserved in patients receiving vaccinations on immunosuppression, except for high-dose glucocorticoids and B-cell depleting therapies. Live-attenuated vaccines should be avoided in immunosuppressed patients. However, it is safe to administer the measles-mumps-rubella booster and varicella zoster virus vaccine to immunosuppressed patients under specific conditions. In addition to the NIP, the non-live seasonal influenza vaccination should be strongly considered for immunosuppressed pedAIIRD patients. CONCLUSIONS: These recommendations are intended for paediatricians, paediatric rheumatologists, national immunisation agencies, general practitioners, patients and national rheumatology societies to attain safe and effective vaccination and optimal infection prevention in immunocompromised pedAIIRD patients.

Effectiveness of the BNT162b2 mRNA COVID-19 vaccine among adolescents with juvenile-onset inflammatory rheumatic diseases.

OBJECTIVES: The effectiveness of the BNT162b2 mRNA COVID-19 vaccine for adolescents with juvenile-onset inflammatory or immune rheumatic diseases (IRDs) is unknown. Several studies have suggested attenuated immunogenicity in patients with IRD. This study evaluated the effectiveness of the BNT162b2 mRNA COVID-19 vaccine in preventing COVID-19 infection in adolescents with juvenile-onset IRD compared with controls without immune rheumatic disease. METHODS: We used data from Clalit Health Services, the largest health-care organization in Israel, to conduct an observational cohort study from February to December 2021, involving 12-18 year-old adolescents diagnosed with IRD. Study outcomes included documented COVID-19 infection in relation to vaccination status and immunomodulatory therapy. We estimated vaccine effectiveness as one minus the risk ratio. Adolescents aged 12-18 years without immune rheumatic disease served as controls. RESULTS: A total of 1639 adolescents with IRD (juvenile idiopathic arthritis, SLE, or familial Mediterranean fever) were included and compared with 524 471 adolescents in the same age range without IRD. There was no difference in COVID-19 infection rates after the second dose of vaccine between those with IRD and controls (2.1% vs 2.1% respectively, P = 0.99). The estimated vaccine effectiveness for adolescents with IRD was 76.3% after the first dose, 94.8% after the second and 99.2% after the third dose. CONCLUSION: We found that the BNT162b2 mRNA vaccine was similarly effective against COVID-19 infection in adolescents with and without IRD. Immunomodulatory therapy did not affect its effectiveness. These results can encourage adolescents with IRD to get vaccinated against COVID-19.

Efficacy, Immunogenicity and Safety of Vaccination in Pediatric Patients With Autoimmune Inflammatory Rheumatic Diseases (pedAIIRD): A Systematic Literature Review for the 2021 Update of the EULAR/PRES Recommendations.

Background: In 2011, the first European League Against Rheumatism (EULAR) vaccination recommendations for pediatric patients with autoimmune inflammatory rheumatic diseases (pedAIIRD) were published. The past decade numerous new studies were performed to assess the safety, efficacy and immunogenicity of vaccinations in pedAIIRD. A systematic literature review (SLR) was therefore performed to serve as the basis for the updated 2021 EULAR/PRES recommendations. Methods: An SLR was performed according to the standard operating procedures for EULAR-endorsed recommendations. Primary outcomes were efficacy, immunogenicity and safety of vaccination in pedAIIRD. The search was performed in Medline, Embase and the Cochrane Library and included studies published from November 2010 until July 2020. Results: The SLR yielded 57 studies which were included for critical appraisal and data extraction. Only 8 studies described the occurrence of vaccine-preventable infections after vaccination (efficacy), none of these studies were powered to assess efficacy. The majority of studies assessed (humoral) immune responses as surrogate endpoint for vaccine efficacy. Studies on non-live vaccines showed that these were safe and in general immunogenic. Biologic disease-modifying antirheumatic drugs (bDMARDs) in general did not significantly reduce seroprotection rates, except for B-cell depleting therapies which severely hampered humoral responses. Four new studies on human papilloma virus vaccination showed that this vaccine was safe and immunogenic in pedAIIRD. Regarding live-attenuated vaccinations, level 1 evidence of the measles mumps rubella (MMR) booster vaccination became available which showed the safety of this booster for patients treated with methotrexate. In addition, level 3 evidence became available that suggested that the MMR and varicella zoster virus (VZV) vaccination for patients on low dose glucocorticosteroids and bDMARDs might be safe as well. Conclusions: The past decade, knowledge on the safety and immunogenicity of (live-attenuated) vaccines in pedAIIRD significantly increased. Data on efficacy (infection prevention) remains scarce. The results from this SLR are the basis for the updated EULAR/PRES vaccination recommendations in pedAIIRD.

Establishing an international awareness day for paediatric rheumatic diseases: reflections from the inaugural World Young Rheumatic Diseases (WORD) Day 2019.

There is a lack of awareness of paediatric rheumatic diseases (PRDs), among the public, and certain groups of healthcare professionals (HCPs), including general practitioners. To help improve international awareness and understanding of PRDs, World yOung Rheumatic Diseases (WORD) Day was established on 18 March 2019. Its aim was to raise awareness of PRDs and the importance of timely referral plus early diagnosis and access to appropriate treatment and support. A steering committee was established, and an external agency provided digital support. A social media campaign was launched in December 2018 to promote it, and analytics were used to measure its impact. Face-to-face and virtual events took place globally on or around WORD Day 2019, with 34 countries reporting events. Examples included lectures, social gatherings and media appearances. A total of 2585 and 660 individuals followed the official Facebook and Twitter accounts respectively, up until WORD Day. The official #WORDDay2019 hashtag was seen by 533,955 unique accounts on 18 March 2019 alone, with 3.3 million impressions. WORD Day 2019 was the first international campaign focused solely on PRDs. It demonstrated that despite awareness events being often resource-light, they can be implemented across a range of diverse settings. WORD Day has now become an annual global awareness event, facilitated by a growing network of patient, parent and professional community supporters.

The European network for care of children with paediatric rheumatic diseases: care across borders.

OBJECTIVES: To provide an overview of the paediatric rheumatology (PR) services in Europe, describe current delivery of care and training, set standards for care, identify unmet needs and inform future specialist service provision. METHODS: An online survey was developed and presented to national coordinating centres of the Paediatric Rheumatology International Trials Organisation (PRINTO) (country survey) and to individual PR centres (centre and disease surveys) as a part of the European Union (EU) Single Hub and Access point for paediatric Rheumatology in Europe project. The survey contained components covering the organization of PR care, composition of teams, education, health care and research facilities and assessment of needs. RESULTS: Response rates were 29/35 (83%) for country surveys and 164/288 (57%) for centre surveys. Across the EU, approximately one paediatric rheumatologist is available per million population. In all EU member states there is good access to specialist care and medications, although biologic drug availability is worse in Eastern European countries. PR education is widely available for physicians but is insufficient for allied health professionals. The ability to participate in clinical trials is generally high. Important gaps were identified, including lack of standardized clinical guidelines/recommendations and insufficient adolescent transition management planning. CONCLUSION: This study provides a comprehensive description of current specialist PR service provision across Europe and did not reveal any major differences between EU member states. Rarity, chronicity and complexity of diseases are major challenges to PR care. Future work should facilitate the development, dissemination and implementation of standards of care, treatment and service recommendations to further improve patient-centred health care across Europe.

Patient's experiences with the care for juvenile idiopathic arthritis across Europe.

BACKGROUND: To assess the views of juvenile idiopathic arthritis (JIA) patients and their parents on the care and treatment they receive in referral pediatric rheumatology centers throughout Europe. METHODS: In a collaboration between physicians and patient associations, a questionnaire was developed, covering various domains of JIA care, including demographics, diagnosis, referrals to various health care professionals, access to pain and fatigue management and support groups, information they received about the disease and awareness of and participation in research. The questionnaire was translated and distributed by parent associations and pediatric rheumatologists in 25 countries, 22 of which were European. After completion the replies were entered on the PRINTO website. Replies could either be entered directly by parents on the website or on paper. In these cases, the replies were scanned and emailed by local hospital staff to Utrecht where they were entered by I.R. in the database. RESULTS: The survey was completed by 622 parents in 23 countries. The majority (66.7%) of patients were female, with median age 10-11 years at the completion of the questionnaire. Frequencies of self-reported JIA categories corresponded to literature. Some patients had never been referred to the ophthalmologist (22.8%) or physiotherapist (31.7%). Low rates of referral or access to fatigue (3.5%) or pain management teams (10.0%), age appropriate disease education (11.3%), special rehabilitation (13.7%) and support groups (20.1%) were observed. Many patients indicated they did not have contact details for urgent advice (35.9%) and did not receive information about immunizations (43.2%), research (55.6%) existence of transition of care clinics (89,2%) or financial support (89.7%). While on immunosuppressive drugs, about one half of patients did not receive information about immunizations, travelling, possible infections or how to deal with chickenpox or shingles. CONCLUSIONS: Low rates of referral to health care professionals may be due to children whose illness is well managed and who do not need additional support or information. Improvements are needed, especially in the areas of supportive care and information patients receive. It is also important to improve doctor patient communication between visits. Physicians can be instrumental in the setting up of support groups and increasing patients' awareness of existing support. Suggestions are given to convey crucial pieces of information structurally and repeatedly to ensure, among other things, compliance.
