Authors' conclusion

RA with JAKi users had a significant risk for hospitalisation, mortality or composite adverse outcomes, especially higher mortality among those without COVID-19 vaccination.

Study context

Population
Patients with RA using b/tsDMARDs, US Collaborative Network in TriNetX, 1 January 2018 to 31 December 2022Propensity score-matched (PSM) cohorts
Participants
2,676 / 2,676 / 967 / 967
Exposure
Janus-associated kinase inhibitors (JAKi) or IL-6i vs TNFi in RA
  • JAKin = 2,676
  • TNFi (vs JAKi)n = 2,676reference
  • IL-6in = 967
  • TNFi (vs IL-6i)n = 967reference
Outcome
COVID-19 incidence and adverse outcomes (hospitalisation, critical care services, mechanical ventilation and mortality)
