Systemic manifestations may develop with potentially severe organ damage including pulmonary, neurological, renal involvement and lymphoma.1 2 SS can be associated with rheumatoid arthritis (RA). Despite this frequent association, few studies have investigated differences between primary Sjögren syndrome (pSS) and SS associated with RA(SS/RA).3 4We have conducted a retrospective single-centre case-controls study. Patients were identified in the Paris-Saclay cohort, a prospectively collected database. Cases were patients fulfilling both ACR/EULAR 2016 criteria for SS and ACR 2010 criteria for RA and followed between 2000 and 2019. For each case, two controls from our local pSS cohort were randomly assigned and matched on disease duration. Disease activity was assessed using the EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI)5 and ESSDAI cumulative score (Cumulative ESSDAI). The latter was calculated considering for each domain, the highest value reached by the patient during his/her follow-up. SS/RA and pSS … ER -
