U1RNP complex, Ro/SSA and La/SSB are major RNA-containing autoantigens associated with autoimmune disorders. Immune complexes (ICs) composed of RNA-containing autoantigens and autoantibodies are suspected to be involved in the pathogenesis of some systemic autoimmune diseases.

A large cohort study shows that severe non-adherence to hydroxychloroquine (HCQ) results in serious risks for SLE flares, damage, and mortality.

In 2018, Park et al showed optimal responses to influenza vaccination in RA patients was best achieved by holding methotrexate for 2 weeks following immunization, with improved humoral responses.
