Patients with rheumatoid arthritis in remission had a rate of flare following vaccination with the Pfizer/BioNtech COVID-19 vaccine that appears to be on par with rates seen with other vaccines in patients with RA, according to results from a small Italian cohort study.
“Our data show a very low flare rate [7.8% (6 of 77)] after the BNT162b2 COVID-19 vaccine in patients with RA in remission and are consistent with previous findings about varicella-zoster virus (6.7%) and hepatitis B virus (2.2%) vaccinations,” Riccardo Bixio, MD, and colleagues from University of Verona (Italy) Hospital Trust wrote in ACR Open Rheumatology. “Because remission is not commonly obtained in the real world, we are aware that our findings may not be generalizable to all patients with RA receiving COVID-19 vaccination.”
Other studies of flare rate after COVID-19 vaccination in patients with a variety of rheumatic and musculoskeletal diseases have reported rates ranging from 5% to 17%, they said.
The 77 consecutive patients from the University of Verona center that conducted the study were all in clinical remission in the 3 months before vaccination based on a 28-joint Disease Activity Score based on C-reactive protein (DAS28-CRP) of less than 2.6, and all had discontinued antirheumatic therapies according to American College of Rheumatology COVID-19 recommendations. The researchers defined flares as agreement between patient and rheumatologist assessments and a DAS28-CRP increase of more than 1.2.
Five of the six people with a flare had it occur after the second dose at a mean of 2.6 days later, and all flares were resolved within 2 weeks using glucocorticoids with or without anti-inflammatory drugs. One flare was called severe. The overall disease activity of the cohort after 3 months was not significantly changed after vaccination.
In noting that five out of the six patients with flares had withdrawn or delayed antirheumatic therapies around the time of vaccination according to ACR recommendations, the authors wrote that “Even if there is no direct evidence that holding therapies could occur in a higher proportion of disease flares, we suggest that clinicians consider this possibility when counseling patients about COVID-19 vaccination.”
The authors had no outside funding for the study and had no potential conflicts of interest to disclose.
