Multiple sclerosis among patients with rheumatoid arthritis: nationwide, pilot study from Poland based on healthcare claims (2009–2021)
Overall, RA was not associated with an increased overall MS risk, as compared with the general population. Young women with seronegative RA may be at a greater risk of MS, which warrants clarification of age, sex, and serotype‑ specific risk disparities in future prospective longitudinal studies. However, clinical vigilance for atypical MS symptoms in young women with RA should be maintained.
