This was a cross-sectional multicenter study where the prevalence of more relevant comorbidities in 2 cohorts was compared. Patients under followup from SJOGRENSER (Spanish Rheumatology Society Registry of Primary SS) and RELESSER (Spanish Rheumatology Society Registry of SLE), and who fulfilled the 2002 American-European Consensus Group and 1997 American College of Rheumatology classification criteria, respectively, were included. A binomial logistic regression analysis was carried out to explore potential differences, making general adjustments for age, sex, and disease duration and specific adjustments for each variable, including CV risk factors and treatments, when appropriate. A total of 437 primary SS patients (95% female) and 2,926 SLE patients (89% female) were included. The mean age was 58.6 years (interquartile range [IQR] 50.0-69.9 years) for primary SS patients and 45.1 years (IQR 36.4-56.3 years) for SLE patients (P  Primary SS patients have a consistently less serious CV comorbidity burden and a lower prevalence of severe infection than those with SLE. In contrast, their risk of lymphoma is greater. YR 2016 FD 2016-11-21 LK http://hdl.handle.net/10668/10393 UL http://hdl.handle.net/10668/10393 LA en DS RISalud RD Feb 15, 2025
