Key clinical point: Findings from this real-world study identified the protective and risk factors associated with SARS-CoV-2 breakthrough infections (BI) in patients with rheumatoid arthritis (RA) who had no COVID-19 infection and received the booster dose of anti-SARS-CoV-2 vaccine.
Major finding: Older patients who were age > 50 years (adjusted hazard ratio [aHR] 0.38; P = .004) and patients receiving conventional synthetic disease-modifying antirheumatic drugs (aHR 0.52; P = .021) had a significantly lower risk for BI, whereas patients receiving anti-interleukin 6 receptor (aHR 2.01; P = 0.039) and anti-CD20 (aHR 2.88; P = .011) treatments had ~2 and ~3 times higher risks for BI, respectively.
Study details: This prospective study included participants who had never been diagnosed with SARS-CoV-2 and had received three doses of the anti-SARS-CoV-2 vaccine, of whom 194 had RA and 1002 were control individuals.
Disclosures: This study was supported by the Italian Ministry of Health and other sources. The authors declared no conflicts of interest.
