Background/Purpose: Primary Sjögren’s syndrome (PSS) is a systemic disease primarily characterized by lymphocytic infiltration of exocrine glands, but lymphocytic infiltration, can also can affect extraglandular tissues. Recently, it has been validated the EULAR SS disease activity index (ESSDAI), that is a clinical index that measure disease activity in PSS. The ESSDAI, includes 12 domains (organ systems: cutaneous, respiratory, renal, articular, muscular, peripheral nervous system, central nervous system, haematological, glandular, constitutional, lymphadenopathic, biological). The ESSDAI is now in use as a gold standard to measure disease activity in clinical studies, and as an outcome measure. The purpose of this study is to evaluate the ESSDAI baseline characteristics in a large Spanish multicenter registry of PSS.
Methods: SJÖGRENSER, is a multicenter descriptive transversal study of a cohort of PSS patients fulfilling European/American consensus criteria 2012, collected from Rheumatology clinics all over Spain. Patients were included by randomisation from an anonymised list provided by every department. Two hundred and ninety eight variables were investigated: epidemiological, clinical, serological characteristics, treatments and complications. Specifically, ESSDAI domains were collected. The score may vary between 0-123. It is considered low activity an ESSDAI <5; moderate activity 5-13, and high activity if ESSDAI is ≥14. Variables were analysed by descriptive statistical methods, using means, medians, and rates, with their deviations and interquartile ranges (p25-p75).
Results: Of 437 patients included, 95% were women, with median age (p25-75): 58.63 years (50,02-67,98 years), and age at diagnosis of 50.24 years (42,99-58,29 years), with a disease evolution of disease of 10.4 years (6-16 years). The median of diagnosis criteria of SS was 5 (4-5). Minor salivary gland biopsy was positive in 69%. Rheumatoid factor, AAN, anti-Ro/SSA and anti-La/SSB and cryoglobulins, were positive in 64,76%, 62,23 %, 93,59%, 67,05%, 3% of patients respectively. Cytopenia was present in 27% of patients and Beta-2 microglobulin serum levels was increased in 22% and C3/C4 reduced in 23% of patients. The median of ESSDAI of our population at enter to the study was 2 (0-4). In 31% of patients, ESSDAI, was 0, in 49% was concordant with low activity, moderate activity in 15% and 5% of patients show high activity. In table, the domains of ESSDAI, at enter to SJÖGREN-SER are shown. Table. ESSDAI results at enter at SJÖGRENSER cohort.

Conclusion: 1. In SJÖGRENSER, 20% of patients show moderate-high ESSDAI results and haematological, biological and articular domains are present in more than 10% of patients. 2. ESSDAI is a suitable tool to define and compare cohorts of patients with PSS.
