<h3>Background</h3> Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease characterized by the involvement of the exocrine glands, mainly salivary and lacrimal glands. Approximately half of patients will experience extraglandular complications throughout their evolution. <h3>Objectives</h3> To characterize the involvement of the nervous system (NS) in patients with pSS. <h3>Methods</h3> Multicenter cross-sectional study of a cohort of patients with pSS, constructed by random selection of pSS patients fulfilling the 2002 American-European Consensus Criteria for pSS<sup>1</sup> from 33 rheumatology units. Through review of clinical records and interview with patients, demographic, clinical, analytical, therapeutic data and disease activity indexes were collected. Univariate analysis was done by Chi square test, Mann-Whitney U test and Student's t test. Multivariate analysis was done by linear logistic regression. A p &lt;0.05 was considered significant. Patients signed an informed consent. The study was authorized by the ethics committees. <h3>Results</h3> 437 patients were included (95% women, median age of 58 years). 65 patients developed NS involvement: 26 patients central NS, 31 peripheral NS and 8 both. Multivariate analysis showed association between NS involvement and atherosclerotic stroke (OR 10.4, 95% CI 2.8-38.5), ear disease (OR 2.1, 95% CI 1.1-4.2) and myopathy (OR 6.5, 95% CI 1.3-31,6). Patients with NS involvement had higher probability of being treated with glucocorticoids (OR 3.3, 95%CI 1.5-7.2) and cyclophosphamide (OR 6.8, 95% CI 1.5-31). <h3>Conclusion</h3> 15% of patients with pSS develope NS involvement that is associated with atherosclerotic stroke, ear disease and myopathy. <h3>Reference</h3> [1] Vitali C. et al.
