E057 A systematic review of new rheumatic immune-mediated inflammatory diseases (R-IMID) following SARS-CoV-2 vaccinations

Abstract

Background/Aims There are sporadic reports about the development of new rheumatic immune-mediated inflammatory diseases (R-IMIDs) in adults after receiving SARS-CoV-2 vaccines. This systematic review (SR) aimed to critically review and summarize the clinical profile, patient demographics, treatment, and prognosis of new-onset R-IMIDs following SARS-CoV-2 vaccination. Methods We retrieved English-language articles (Case reports and series and observational studies) on new-onset R-IMIDs following SARS-CoV-2 vaccination, published until June 2022, from standard databases (MEDLINE, Embase, Cochrane). The search strings used during the literature search incorporated ‘SARS-CoV-2 vaccination’ (along with related MeSH terms) and various key terms for R-IMIDs [which included (but was not limited to) inflammatory arthritis, connective tissue disease (CTD), vasculitis, systemic lupus erythematosus, Sjogren’s syndrome, sarcoidosis, systemic sclerosis, idiopathic inflammatory myositis, anti-synthetase syndrome, Adult-onset Stills disease (AOSD), giant cell arteritis (GCA), and polymyalgia rheumatica (PMR)]. The protocol was registered in PROSPERO (CRD42022318561). Results Of the total 2179 articles retrieved, 1986 articles were excluded following the title-abstract screening, and 107 articles that did not meet inclusion criteria. We included the remaining 86 articles (130 cases) upon full-text screening. Furthermore, we added four articles (six cases) based on a manual search, comprising 90 articles (136 cases) for final analysis. These 136 new R-IMID cases were reported from 27 different countries. Of these, more than one-third of the cases were reported from three countries (viz., Italy, Japan, and the USA). The patients had a mean age of 57 (range:17-90) years, and the majority were females (63.0%). Most patients developed R-IMIDs after receiving Pfizer-BioNTech vaccine (76; 55%), followed by Oxford AstraZeneca vaccine (35; 25%). The mean duration between SARS-CoV-2 vaccination and R-IMIDs development was 9.2 (range:1-90) days. The second dose of the vaccine resulted in more R-IMIDs (74;54%) than the first (53;39%). CTDs (34; 25%) and small vessel vasculitis (33; 24%) were the commonest R-IMID manifestations, followed by inflammatory arthritis and AOSD, each in 13 (9.5%) cases. Nearly half of the patients with CTDs had Idiopathic Inflammatory Myositis. PMR and GCA accounted for 16 (11.7%) and 5 (3.6%) cases, respectively. However, no cases of axial spondylarthritis were reported. Most (118; 86%) R-IMID patients were treated with corticosteroids, with a small number receiving steroid-sparing drugs, such as methotrexate, rituximab and cyclophosphamide. Most (125; 91%) went into either disease remission or improvement following the treatment. Only three patients were admitted to the intensive care unit (ICU) to manage their disease; One of them died due to fatal myositis and rhabdomyolysis; two surviving ICU patients had ANCA-associated vasculitis with lung involvement. Conclusion Although rare, this SR highlights the emergence of de novo R-IMIDs following SARS-CoV-2 vaccination. We cannot confirm the causality between the vaccination and the onset of R-IMID. However, further research is warranted in this area. Disclosure A. Nune: None. K. Bora: None. K.P. Iyengar: None. B. Barman: None. V. Durkowski: None. S. Venkatachalam: None. S. Bilgrami: None. L.
