P061 COVID vaccine made my joints hurt: effect of COVID vaccine on systemic rheumatic disease

Abstract

Abstract Background/Aims Vaccination against SARS-CoV-2 is crucial for patients with systemic rheumatic diseases (SRDs) who may be at increased risk of severe outcomes post-COVID-19. Sparse data suggests vaccines used for COVID -19 may be associated with SRD flares, possibly from molecular mimicry triggering immune activation or non-specific adjuvant effects. As SRD flares are associated with disease deterioration, increased flares could have serious clinical implications. We report the interim results of a survey evaluating SRD flare incidence post-SARS-CoV-2 vaccine. Methods We surveyed 200 patients of different age group with different SRDs via telephone or paper copy during their appointment in Rheumatology department at North Cumbria Integrated Care NHS Foundation Trust, from September 2022 to March 2022 who received at least one dose of Pfizer or Astra Zeneca vaccine. The results of the survey were recorded. Results The mean age of the patients was 62.5 years. 63% of the patients (N-126) were females. 53 (26.5 %) of these patients had Rheumatoid Arthritis (RA), 43 (21.5 %) had Psoriatic Arthritis, 37 (18.5%) had Sero-ve Spondyloarthropathy, 22 (11%) had Ankylosing Spondylitis, 16 (8 %) had CTD, 12 (6%) had PMR, 10 (5%) Vasculitis and 7 (3.5%) had Palindromic arthritis. 96 (48%) of these patients were on synthetic DMARDs, 56 (28%) on Biologic DMARDs and 41 (20.5%) were on combination. 7(3.5%) patients were on NSAIDS. The most common adverse effects from the vaccine were pain at the site of injection and generalized body aches in 90 % of patients followed by fatigue in 80%. 22% had fever. 21 (10.5 %) patients had flare up of their existing rheumatic disease after the first dose and 22 (11%) had a flare after 2nd dose and another 24 (12%) after the 3rd dose. 30 (15%) patients had some flare up after two doses. Out of these 26 had mild flare up and improved with Paracetamol/codeine. 30 had mild to moderate flare required different NSAIDs and 21 had severe requiring a course of prednisolone. 3 of these patients required step up of DMARDS. These flares were described as typical, suggesting these symptoms were not vaccine’s adverse effects being misreported as disease flares. Conclusion Interim data from our cohort demonstrates about 12% of patients had severe flare up, with some lasting for weeks requiring switching of DMARDs. Although SARS-CoV-2 vaccine might be associated with some flare up in SRD, but the morbidity and mortality of non-vaccinated patients with SRD can be very devastating signifying the importance of the vaccine. Further data is required for a wider cohort. Disclosure A. Munir: None. H. Awais: None.
